The survey was conducted on rational use of antibiotics to observe that whether the antibiotics are used rationally or not, and if not to find out the factors, which are responsible most for irrational use of antibiotics. Since the irrational use ultimately lead to antibiotic resistance, which is considered as everybody’s problem, so it is very much important to find out the reasons behind resistance and take some necessary steps to solve the problems.
Rationale and Objective of the Work:
Antibiotics are agents which are used to kill or inhibit the growth of microorganism. This class of drugs should be used by counseling with the registered physicians; otherwise improper selection of antibiotic may develop resistance. Not only the improper selection but also some other factors, such as ignorance of patients about course of antibiotics, overuse, etc are responsible for antibiotic resistance.
In comparison to developed countries, the irrational use of antibiotics occurs more frequently in developing or least developed countries like Bangladesh, particularly at PHC level. That is why Muktagachhha Upazila Health Complex has randomly been selected for the survey on rational use of antibiotics.
General Health Matter of Bangladesh:
Bangladesh is considered a developing country with more than 75% of the total (150 million) population living in rural areas. About 36% of the population continue to live below the national poverty line (<US$1/day). Basic needs of living particularly health and education remain largely unmet and only less than 40% of the population has access to basic healthcare. Distribution of health workers (per 1000 population) in Bangladesh is physicians 0.26, nurses 0.14and pharmacist 0.06. Per capita total expenditure on health only US$ 2.84 in comparison to US$ 30-40 per capita, the minimum required for essential health interventions in low income countries. Though majority of the population live in rural areas, the government healthcare system remains a very minor source of health care there. Around 26% of professional posts in rural areas remain vacant and there is high rate of absenteeism (about 40%). Treatments in the rural areas are mainly (about 45%) provided by unqualified health personnel including medical assistants, mid-wives, village doctors, community health workers in comparison to that by qualified medical graduates (only 10-20%). Over-prescribing and inappropriate prescribing are very common in the country due to unethical practice of both health professionals and drug manufacturers. (Islam MS, 2006)
Primary Health Care:
Primary health care, often abbreviated as PHC, is “essential health care based on practical, scientifically sound and socially acceptable methods and technology made universally accessible to individuals and families in the community through their full participation and at a cost that the community and the country can afford to maintain at every stage of their development in the spirit of self-determination” (Alma Ata international conference definition).
It was a new approach to health care that came into existence following this international conference in Alma Ata in 1978 organized by the World Health Organization and the UNICEF.
The primary care in the public sector is organized around the Upazila Health Complex (UHC) at sub-district level which works as a health-care hub. These Units have both in- and out-patient services and care facilities. Most commonly, they have in-patient care support with 31 beds, while some UHC have over 50 beds. Many UHC Units have a package service called “comprehensive emergency obstetric care services” (EOC) available, with an expert gynaecologist, an anaesthetist and skilled support nurses on duty round-the-clock and basic laboratory facilities. At a lower tier, the Union Health and Family Welfare Centre (UHFWC) are operational, constituted with two or three sub centers at the lowest administrative level, and a network of field-based functionaries. The public sector field-level personnel are comprised of Health Assistants (HAs) in each union who supposedly make home visits every two months for preventive healthcare services, and Family Welfare Assistants (FWAs) who supply condoms and contraceptives pills during home visits. Recently some of the female HAs and FWAs have been trained as birth attendants (skilled birth attendants – SBAs), to provide skilled services within a household setting. The number of health assistants is determined according to the size of the population. The Health Assistants and Family Welfare Assistants are supervised by a Health Inspector (HI) and a Family Planning Inspector (FPI) respectively, posted at the union level. The UHC is staffed by ten qualified allopathic practitioners and supporting staff, while the UHFWCs are staffed by professionals such as a Medical Assistant (MA/SACMO) and mid-wife (Family Welfare Visitor), both trained in formal institutions. The Union Health and FamilyWelfareCenters (UHFWCs) provide out-patient care only.
Above the sub district are the district hospitals (100-250 beds) and medical colleges (serving a group of districts with around 650 beds) providing secondary care, and national tertiary level care facilities. A common tendency is observed in terms of utilization – a stark imbalance in service utilization at public health facilities. There is low utilization of most facilities at the primary level (Upazila and below) and overutilization of facilities at the secondary and tertiary levels. (Internet 1)
Present Status of PHC:
Eight Elements of PHC
Since the inception PHC services in Bangladesh have been rendered in terms of 8 elements: health education, nutrition, adequate and safe water and sanitation, maternal and child health, immunization, prevention and control of endemic diseases, treatment of common ailments and injuries and provision of essential drugs. In the 5th five year plan, Health and Population Sector Programme 1998-2003 (HPSP), these services were remodeled as the Essential Service Package with prioritization of the most of the PHC activities. Current, 2003-2010, Health, Nutrition and Population Sector Programme (HNPSP) includes nutrition with essential service package as the essential service delivery (ESD) programme.
Other Elements of PHC:
In addition to eight essential elements, PHC activities in Bangladesh cover prevention and management of non-communicable diseases (NCDs), interventions relating to arsenicosis, environmental and occupational health, health of the senior citizens, adolescents and young peoples, injury prevention and management and violence against women. Reduction of morbidity and premature mortality due to NCDs focuses on integrated preventive actions linked to reducing risk factors of major NCDs: cardiovascular disease, cancer, and diabetes. The interventions are carried out at different levels to limit tobacco use, an unhealthy diet, and physical inactivity. While at present, there is no comprehensive occupational health service in Bangladesh; health of large number of workers in the corporate industries is taken care of according to Factory Act of 1965. Proposed strategies to address the environmental health in the current HNPSP include strengthening the information base through prioritized studies on the extent of environmental and occupational hazards and creating advocacy and mass awareness about environment and occupational health hazards. (Internet 2).
Primary Healthcare Facilities Provided in Bangladesh:
‘Healthcare for All’ has been the catchphrase for many developing countries of the world, including Bangladesh. According to Article 15 and 18 (1) of the Constitution of Bangladesh access to health is ensured for every citizen of the country. In 1978 Bangladesh became a signatory to the Alma-Ata Declaration. But even after over three decades of such lofty declarations Bangladesh is far from being a nation that provides access to healthcare to all its people. True, in the last 37 years of our independence there have been significant successes in sanitation. With the majority of the population being poor, underfed and undernourished and an inefficient, inaccessible public health care system, health, or rather the threat to it, has become the biggest obstacle to development. Access to healthcare, seems to be the first and most important step towards achieving the ‘Health for All’ goal.
It is not as if we never had any National Health Policy. Three consecutive governments promulgated drafts of the National Health Policy in 2000, 2006 and in 2008. But health has never been given the importance in the national budget as it deserved. The government has spent around only US$ 4 per person per year, while the proposed National Health Policy 2000 set the requirement of minimum US$ 12 per person. According to the World Health Organization (WHO), however, the ideal figure is a minimum of US$ 34 per person per year in this field. This year’s proposed budget for the health sector had an allocation of only approximately 6000 crore taka including salaries and development works. Inefficiency in health governance, corruption, misuse, lack of transparency, incompetence in fund management, partition policy and favoritism result in funds not being allocated properly.
Health statistics are quite staggering. Only 40 percent of the population have access to health services provided by the government and private organizations, as well as, development agencies, 25 percent of the dying do not get the opportunity to see a doctor before death, 70 percent of pregnant women are deprived of getting prenatal check up, and 70 percent of women suffer from anemia. (Kamol E, 2009)
Bangladesh started with pilot projects in 6 Upazils in the year 1979-80 in the lights of which subsequently PHC Program started in Bangladesh in 1980. The basis of the policy of the government was to provide health care to the un-served and underserved population as far as possible, at their door steps, at a cost that the people can afford. Interventions of operationalizing PHC in Bangladesh were based on 3 important strategies:
- provision of basic essential equipments, and
- ensuring uninterrupted supply to facilitate effective preventive, curative, and rehabilitative services to the vulnerable, the disadvantaged and the poor.
In Bangladesh the Upazila, Union and Ward levels constitute the operational levels of PHC, while the district, divisional and national levels provide managerial support and technical backstopping to the operational levels. The first evaluation of the national HFA strategy in 1986 revealed that due to various constraints such as inadequacy in the managerial process, lack of adequate resources, bias towards curative medicine, lack of coordination and community involvement, the concept and principle of PHC could not be translated into action. As such, in 1988 the government initiated the program known as “Intensified PHC Program” which started in two upazilas in two districts and by present gradually extended to cover 237 upazilas in 20 districts, which is approximately half of all upazilas in the country. The Intensified PHC programme has demonstrated success in developing useful working mechanism at Upazila level and below by adopting functional integration of health and family planning services under the package of PHC; community mobilization through the involvement of Village Health Volunteers (VHV) and TBAs; inter-sectoral action through “action committees” at different levels; and strengthening of project management at union, Upazila and district levels.

An antibiotic is a drug that kills certain kinds of bacteria but which is generally harmless to the host and is used to treat infection. The term was originally used to describe only antibacterial formulations derived from living organisms but is now used in reference to synthetic antimicrobials such as the sulfonamides.
In general, the term can also apply to substances that affect prions, viruses, fungi, worms or any other intracellular or extracellular parasite, but the antibacterial kind are the most common. Generally, the antibiotics are not effective in viral infections.
History of Antibiotic Discovery:
The first antibiotic to be discovered was penicillin. Alexander Fleming had been culturing bacteria on an agar plate with an accidental fungal contamination, and noticed that the culture medium around the mould was free of bacteria. He had previously worked on the antibacterial properties of lysozyme, and so was predisposed to make the correct interpretation of what he saw: that the mold was secreting something that stopped bacterial growth. Though he was unable to produce the pure material (the beta-lactam ring in the penicillin molecule was not stable under the purification methods he tried), he reported it in the scientific literature. Since the mold was of the genus Penicillium, he named this compound penicillin. With the increased need for treating wound infections in World War II, resources were poured into investigating and purifying this compound, and a team led by Howard Florey succeeded in producing large quantities of the purified active ingredient. Antibiotics soon came into widespread use.
The discovery of antibiotics, along with anesthesia and the adoption of hygienic practices by physicians (for example, washing hands and using sterilized instruments) revolutionized medicine – it has been said that this is the greatest advance in health since modern sanitation. They are often called “magic bullets”: drugs which target bugs without greatly harming the host.
Classes of Antibiotics:
There are many way to classify antibiotics. Based on chemical structure antibiotics can be classified as:
- Beta-lactam ring antibiotics
- Cephalosporins and Cephamycins
- Monocyclic beta-lactams
- Glycopeptide Antibiotics
- Other important antibiotics:
- Fusidic acid
Based on mechanism of action (that is, the mechanism by which they selectively poison bacterial cells) antibiotics can be classified as:
- antibiotics which interfere with cell-wall synthesis
- beta-lactams, including penicillins and cephalosporins; mono-lactams, such as Imipenem; vancomycin, bacitracin
- antibiotics which interfere with bacerial protein synthesis
- antibiotics which bind to the 50S ribosomal unit
- Lincosamides/lincosides including clindamycin and lincomycin; chloramphenicol
- antibiotics which bind to the 50S ribosomal unit
- antibiotics which interfere the 30S ribosomal unit
- tetracyclines; aminoglycosides including gentamicin
- drugs with inhibit folate sytheisis
- sulfonamides and tirmethoprim
- drugs which interfere with DNA synthesis
- rifampin, metronidazole, quinolines, novobiocin
- drugs which interfere with cell membrane function
- polymyxin B, Gramicidin
Antibiotics can also be classified by the organisms against which they are effective, and by the type of infection in which they are useful, which depends on the sensitivities of the organisms that most commonly cause the infection and the concentration of antibiotic obtainable in the affected tissue. (Internet 3).
Antibiotic resistance is the ability of a microorganism to withstand the effects of antibiotics. It is a specific type of drug resistance. Antibiotic resistance evolves via natural selection acting upon random mutation, but it can also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange. If a bacterium carries several resistance genes, it is called multi-resistant or, informally, a superbug. The term antimicrobial resistance is sometimes used to explicitly encompass organisms other than bacteria.
Antibiotic resistance can also be introduced artificially into a microorganism through transformation protocols. This can aid in implanting artificial genes into the microorganism. If the resistance gene is linked with the gene to be implanted, the antibiotic can be used to kill off organisms that lack the new gene.
Types of Antibiotic Resistance:
Some bacteria are intrinsically resistant to certain of the antibiotics. Example: Gram-positive bacteria are much less susceptible to polymixins than Gram-negative bacteria. [The “Gram” designations refer to the behavior of the bacteria when stained with the Gram stain; this behavior is a reflection of the very different organization of their cell walls.]
Many bacteria acquire resistance to one or more of the antibiotics to which they were formerly susceptible.
Bacteria develop resistance by acquiring genes encoding proteins that protect them from the effects of the antibiotic. In some cases the genes arise by mutation; in others, they are acquired from other bacteria that are already resistant to the antibiotic. The genes are often found on plasmids which spread easily from one bacterium to another — even from one species of bacterium to another.
Mechanisms of Antibiotic Resistance:
The four main mechanisms by which microorganisms exhibit resistance to antimicrobials are:
- Drug Inactivation or Modification: e.g. enzymatic deactivation of Penicillin G in some penicillin-resistant bacteria through the production of β-lactamases.
- Alteration of Target Site: e.g. alteration of Penicillin Binding Protein (PBP) —the binding target site of penicillins—in Methicillin Resistance MRSA and other penicillin-resistant bacteria.
- Alteration of Metabolic Pathway: e.g. some sulfonamide-resistant bacteria do not require para-aminobenzoic acid (PABA), an important precursor for the synthesis of folic acid and nucleic acids in bacteria inhibited by sulfonamides. Instead, like mammalian cells, they turn to utilizing preformed folic acid.
- Reduced Drug Accumulation: by decreasing drug permeability and/or increasing active efflux (pumping out) of the drugs across the cell surface. (Internet 4)
Factors Contributing to Antibiotic Resistance:
Since their introduction, antimicrobials (antibiotics) have played an essential role in decreasing morbidity and mortality due to infectious diseases. However, infectious diseases remain the leading cause of death worldwide. In recent years, infections caused by resistant strains of microorganisms have been increasing worldwide. The alarm bells are sounding. Concern has been echoed by the world’s health community, with the adoption of a resolution on antimicrobial resistance at the World Health Assembly in 1998. (WHO/CDS/CSR/DRS/99.2)
Factors Contributing to Antibiotic Resistance are as follows:
a. Lack of knowledge
This lack of knowledge is assumed to play a role in irrational prescribing (Kunin 1987). In many countries, the dispensers of drugs also may not be formally trained as dispensers or as pharmacists.
b) Inadequate diagnosis
In areas where diagnostic facilities are not readily available (or are entirely absent), thus making differential diagnosis, organism identification, and knowledge of antimicrobial susceptibility patterns difficult, greater amounts of antimicrobials are often prescribed to ‘cover any possible infection’ (Bosu 1997). As resistance continues to become more prevalent, prescribers may be more likely to utilize broader spectrum antimicrobials for empiric therapy and prophylaxis of infections (Yu 1991; Goldmann 1997).
c) Incorrect drug selection for treatment or prophylaxis of infections
In Bangladesh, it was determined that 50% of all the prescriptions for antimicrobials in a hospital unit were considered inappropriate (Hossain 1982).
d) Dose/duration/route incorrectly prescribed
Long treatment duration and sub-therapeutic or sub-optimal dosages have been correlated with increases in selective resistance (Rice 1990; Guillermot 1998).
e) Prescriptions in response to patient pressures
Patient demand for antimicrobials has been shown to increase unnecessary antimicrobial prescriptions (Bauchner 1997; Bosu 1997; Macfarlane 1997). In a study by Macfarlane et al. (1997), patient pressure was the most common influence in the decision to prescribe antimicrobials even when the physician thought they were not indicated. This type of prescribing can lead to a ‘perpetual’ cycle if patients repeatedly receive antimicrobials even if they are not indicated, which then enhances their belief that antimicrobials are necessary and they continue to request them (Little 1997; Macfarlane 1997)
f) Fear of litigation
Fear of litigation has been suggested as one reason physicians over-prescribe antimicrobials (Fidler, 1998).
g) Financial gain
In countries where physicians are underpaid, pharmaceutical companies have been known to pay prescribers a commission for prescribing their products (Norrby 1996). In addition, pharmacists and dispensers gain financially from over-dispensing and through dispensing more expensive broad-spectrum agents when cheaper narrow spectrum agents would suffice.
h) Response to promotional pressure
It is recognized that often the main resources of drug information for prescribers are drug representatives and commercially oriented publications (Bosu, 1997).
i) Self medication
Self medication is often cited as a major contributing factor to drug resistance (Vuckovic 1997). In a Brazilian study, it was determined that the three most common types of medication used by villagers were antimicrobials, analgesics and vitamins with the majority being prescribed by a pharmacy attendant or purchased by the patient without prescription (Haak 1988).
j) Poor adherence
A lack of patient understanding and provider communication led to most instances of non-adherence (Sackett 1979; Buckalew 1986). This factor is critical as often patients who fail to complete therapy (such as in the case of tuberculosis) will relapse and require retreatment. Previous treatment is considered an important factor in the selection of resistant bacteria (Bloom 1992).
k) Poverty-associated undertreatment
A lack of access to drugs due to economic hardship has been described as a factor for impacting resistance as appropriate therapy can be interrupted. In many developing countries, for economic reasons antimicrobials are purchased in single doses and may be only taken for a couple of days until the patient ‘feels better’. This action has the potential for impacting the emergence of resistance (Couper 1997; UK Department of Health 1998).
National Drug Policy Promulgated in 1982 :
In response to WHO’s essential drugs concept such as access to essential medicines, quality of all medicines and rational use of drugs, Bangladesh pioneered a National Drug Policy (NDP) in 1982. Main objectives of this policy were to ensure easy accessibility to essential drugs with affordable price, standard quality of drugs and rational use of drugs through appropriate prescribing and dispensing the health care professionals. The Directorate of Drug Administration (DDA) under the Ministry of Health & Family Welfare, Government of the People’s Republic of Bangladesh, is the drug regulatory authority of the country. Mission of the DDA is to ensure that the common people have easy access to useful, effective, safe and good quality essential and other drugs at affordable price. All matters related to drugs and medicines are regulated in Bangladesh by the Drugs Act 1940 and the rules made there under. In addition to that, the Government adopted the NDP in 1982 and The Drugs (Control) Ordinance, 1982 was promulgated to implement it. The Ordinance controls manufacture, import, distribution, sale, pricing, and advertisement of all essential Allopathic drugs and medicines and for prohibiting production, sale and use of non-essential and unnecessary or less necessary drugs and medicines in the country. At present, the DDA has 33 district offices and all officers function as “Drug Inspector” pursuant to the drug laws. Besides, a number of Committees, such as Drug Control Committee (DCC) Standing Committee for procurement and import of raw materials and finished drugs, Pricing Committee and a number of other relevant Committees. To test the quality of pre-registration and post-marketed drugs and medicines, there are two government Drug Testing Laboratories in the country, one in Chittagong under the direct administrative control of the DDA and the other in Dhaka under the control of the Institute of Public Health (IPH) of the Directorate General of Health Services. (Islam MS, 2006).

Antibiotics at PHC Level

Source: Survey Report of Muktagaccha UHC, Mymensingh
According to National Drug Policy promulgated in 1982 essential antibiotics should be used at PHC level of Bangladesh, but only about 35 percent of essential antibiotics are used now at PHC level, which is irrational.
Since, the rural people are getting essential antibiotics free of cost, so there is a great chance of patient compliance, which ensures the rational use of antibiotics.
Rational Use of Antibiotics:
The Conference of Experts on the Rational Use of Drugs, convened by the World Health Organization in Nairobi in 1985 defined that
“Rational use of drugs requires that patients receive medications appropriate to their clinical needs, in doses that meet their own individual requirements for an adequate period of time, and the lowest cost to them and their community.”
The definition implies that rational use of drugs, especially rational prescribing should meet certain criteria as follows:
Appropriate indication: The decision to prescribe drug(s) is entirely based on medical rationale and that drug therapy is an effective and safe treatment
Appropriate drug: The selection of drugs is based on efficacy, safety, suitability and cost considerations.
Appropriate patient: No contra-indications exist and the likelihood of adverse reactions is minimal, and the drug is acceptable to the patient.
Appropriate information: Patients should be provided with relevant, accurate, important and clear information regarding his or her condition and the medication(s) that are prescribed.
Appropriate monitoring: The anticipated and unexpected effects of medications should be appropriately monitored. (Internet 5)
General Principles in the Use of Antibiotics:
Antibiotics are one of the most commonly prescribed drugs today. Rational use of antibiotics is extremely important as injudicious use can adversely affect the patient, cause emergence of antibiotic resistance and increase the cost of health care. Prescribing an antibiotic comprises several phases:
i) perception of need – is an antibiotic necessary?
ii) choice of antibiotic – what is the most appropriate antibiotic?
iii) choice of regimen : what dose, route, frequency and duration are needed?
iv) monitoring efficacy : is the treatment effective?
Is an antibiotic necessary?
Antibiotics are generally only useful for the treatment of bacterial infections. It is important to remember that not all fevers are due to infections and not all infections are caused by bacteria. The majority of infections seen in general practice are of viral origin and antibiotics can neither treat viral infections nor prevent secondary bacterial infections in these patients. Even where a bacterial aetiology is established, an antibiotic may not be always necessary. Many bacterial infections resolve spontaneously. Minor superficial skin infections may be more suitably treated with a local antiseptic. Collections of pus should be drained surgically and if drainage is adequate, antibiotics are often not required.
Choice of an antibiotic:
The successful outcome of therapy would depend very much on the choice of the antibacterial agent. In the process of selecting an antibiotic, three main factors need to be considered; the aetiological agent, the patient and the antibiotic.
The aetiological agent:
Determination of the aetiological agent depends on a combination of clinical acumen and laboratory support. In many instances an antibiotic prescription has to be made based on the clinical diagnosis (empirical therapy). Even where a bacteriology report is available it is necessary to interpret the report. Bacterial isolates from culture specimens may represent normal flora, colonisers or contaminants rather than true pathogens. Sensitivity results when available are at best only a guide to treatment. Laboratory reports should always be viewed in the light of clinical findings.
Several patient factors have to be considered in selecting an antibiotic. Age is an important factor. The very young and the very old tend to be more prone to the adverse effects of the antibiotics. Neonates have immature liver and renal functions which affect their ability to metabolise or excrete antibiotics. Antibiotics and their metabolites may adversely affect growing tissues and organs in children. Elderly patients are more likely to suffer from nephrotoxicity and allergic reactions. Dosage modifications would also have to be made in those patients with hepatic or renal impairment. Antibiotics can also give rise to severe toxic reactions in patients with certain genetic abnormalities eg sulphonamides in patients with glucose-6-phosphate dehydrogenase deficiency. Antibiotics should as far as possible be avoided in pregnancy and when it is necessary to use an antibiotic, betalactam antibiotics and erythromycin are probably the safest. A history of allergy to antibiotics should always be sought before administration. Routine intradermal test doses for penicillin allergy is of little value and may even be dangerous.
The clinician should have adequate knowledge of the pharmacokinetic properties of the antibiotic he uses. Antibiotics vary in their ability to be absorbed orally or to cross the blood brain barrier and these factors will affect their routes of administration. The ability of the antibiotic to achieve therapeutic concentrations at the site of infection is another important consideration thus antibiotics used for treating urinary infections should ideally be concentrated in urine. Some antibiotics have very severe toxic effects and are best avoided in certain conditions. The doctor should also be aware of drug-drug interactions since many antibiotics can interact with other non-antibiotic drugs. Finally the cost of the antibiotic is also of major concern. In calculating costs it is perhaps more reasonable to take into account the total cost of treatment rather than just the actual cost of antibiotic per dose. The route of administration, the necessity for monitoring antibiotic levels and the patient’s length of stay in hospital can affect the cost of treatment as well. The patient’s compliance to medication is an important factor for consideration in the choice of antibiotics.
Choice of regimen Parenteral or oral:
Whether the route of administration should be oral or parenteral would depend on whether the patient is able to take oral treatment reliably. In cases of severe sepsis where rigors, hyperthermia/hypothermia, tachycardia and hypotension are present, intravenous therapy should be instituted. When in doubt it would be safer to commence intravenous treatment and review the treatment daily.
Duration of treatment:
Except for a few conditions, the optimum duration of antibiotic treatment is unknown. Many antibiotics are often presribed for duration of 5-7 days. Nevertheless it is reasonable to discontinue therapy even after a shorter period if the patient’s symptoms have resolved. There are however certain infections where prolonged treatment is necessary (Table 1.3). In some conditions eg uncomplicated cystitis in women and gonococcal urethritis in males, single dose regimens have been shown to be effective.
Table 1.3: Conditions where a minimum duration of treatment has been established
|Infection||Minimum duration of treatment|
|Tuberculosis||4 -6 months|
|Empyema and lung abscess||4 – 6 weeks|
|Atypical pneumonia||2 – 3 weeks|
|Pneumococcal meningitis||7 days|
|Pneumococcal pneumonia||5 days|
Early review of Response
A routine early review (3 days after commencing treatment) of the patient’s response is important in order to ensure that the patient is receiving appropriate treatment. After review the doctor will have to decide whether to:
i) continue with the present regimen
ii) increase the level of treatment by changing from oral to parenteral; increasing the dose or changing to a broader spectrum antibiotic
iii) decrease the level of treatment by changing from parenteral to oral, decreasing the dose or changing to a more specific narrow spectrum antibiotic
iv) stopping the antibiotic if the infection has resolved; the objective of treatment is
v) achieved or the diagnosis has been changed.
Causes of non-response to antibiotics
A patient may fail to respond to an antibiotic for a number of reasons which include:
i) the aetiological agent is resistant to the antibiotic
ii) the diagnosis is incorrect
iii) the choice of antibiotic is correct but the dose and/or route of administration is wrong
iv) the antibiotic cannot reach the site of infection
v) there is a colletion of pus that should be drained surgically or a foreign body/devitalized tissue that should be removed
vi) there is secondary infection
vii) antibiotic fever
viii) non-compliance of the host (V K E Lim, et al, 1993)
Irrational use of Antibiotics:
Common patterns of irrational prescribing may be manifested in the following forms:
The use of drugs when no drug therapy is indicated, e.g., antibiotics for viral upper respiratory infections,
The use of the wrong drug for a specific condition requiring drug therapy, e.g., tetracycline in childhood diarrhea requiring ORS,
The use of drugs with doubtful/unproven efficacy, e.g., the use of antimotility agents in acute diarrhea,
The use of drugs of uncertain safety status, e.g., use of dipyrone (Baralgan, etc.),
Failure to provide available, safe, and effective drugs, e.g., failure to vaccinate against measles or tetanus, failure to prescribe ORS for acute diarrhea,
v The use of correct drugs with incorrect administration, dosages, and duration, e.g., the use of IV metronidazole when suppositories or oral formulations would be appropriate.
The use of unnecessarily expensive drugs, e.g. the use of a third generation, broad-spectrum antimicrobial when a first-line, narrow spectrum, agent is indicated.
Some examples of commonly encountered inappropriate prescribing practices in many health care settings include:
Overuse of antibiotics and antidiarrheals for non-specific childhood diarrhea,
Indiscriminate use of injections, e.g., in malaria treatment,
Multiple drug prescriptions,
Excessive use of antibiotics for treating minor ARI.
Minerals and tonics for malnutrition.
Factors Underlying Irrational Use of Drugs:
There are many different factors which affect the irrational use of drugs. In addition, different cultures view drugs in different ways, and this can affect the way drugs are used.
The major forces can be categorized as those deriving from patients, prescribers, the workplace, the supply system including industry influences, regulation, drug information and misinformation, and combinations of these factors.
Patients – drug misinformation
Prescribers – lack of education and training
inappropriate role models
lack of objective drug information
generalization of limited experience
misleading beliefs about drugs efficacy
Workplace – heavy patient load
– pressure to prescribe
– lack of adequate lab capacity
– insufficient staffing
Drug Supply System – unreliable suppliers
expired drugs supplied
Drug Regulation – non-essential drugs available
lack of regulation enforcement
Industry – promotional activities
All of these factors are affected by changes in national and global practices. For example, the frequent use of injections is declining in many African countries because of the fear of AIDS. In some countries, however, the use of injectibles remains high due to false assumption of prescribers that injections will improve patient satisfaction and that they are always expected by the patients.
Impact of Inappropriate Use of Antibiotics:
The impact of this irrational use of antibiotics can be seen in many ways:
Reduction in the quality of drug therapy leading to increased morbidity and mortality,
Waste of resources leading to reduced availability of other vital drugs and increased costs,
Increased risk of unwanted affects such as adverse drug reactions and the emergence of drug resistance, e.g., malaria or multiple drug resistant tuberculosis,
Psychosocial impacts, such as when patients come to believe that there is “a pill for every ill”. This may cause an apparent increased demand for drugs.
The study from which the data will be presented herein were gathered began in 2009. Around 2-Month period, this Survey is collecting data from a cross-sectional sample of 135 men and women in the Union level and interviewing 23 Doctors. An important point of significance in this study lies in the uniqueness of its subject pool.
First, the subjects are Physicians, who are responsible to prescribe the Antibiotics for the disease due to infection.
Second , the patients who are attached with the Antibiotic use due to the prescription from the physician.
All research subjects receive a Brief History Interview of Physician & the Patient using the Antibiotics..

what are the reason behind the antibiotics resistance?
In the rural level of Bangladesh, the patients are mainly concernment about the cure of their infection rather then adverse effect of the received treatment .Many reasons are plays important role in becoming resistant in certain generation of drug. Unfortunately, some of the reasons are delivered. As the educational status in ground level is almost one-fourth of educational status in urban area, the patients are likely very less concerned about their treatment strategy. Their dependency towards physicians & medical assistant’s have contributed largely in present situation.
In the ground level the following reasons are found to make a community resistant in certain class of drug.
- Tendency of patient to not stick to the therapy till completion of course
- Wrong selection of antibiotic
- Inadequate dose
- Random use(misuse)
- Irrational use of broad spectrum antibiotic specially in rural area by non-graduate village doctor
- Use of costly latest generation of antibiotic due to rapid recovery. (Soulsby EJ ,2005)

Whether the rural people are getting essential Antibiotics Free of cost?
About 25%rural people are getting essential antibiotics free of cost & the rest 75% people are purchase the antibiotics from outside like pharmacy or medical store.
In UHC of Chandina in comilla many essential drug are prescribed. But few of them are disperse free of cost among patients. Indoor patients receives this essential drug time to time from nurse. The prescription of the doctors shows that maximum preside drug are not available in the hospital pharmacy. Patients have to buy those drugs from the nearer pharmacy (private).
Drug that are given free of cost are maximum 1st generation of that class, of the found out of date. Moreover for proper diagnosis of disease the patient have to visit nearer diagnostic center (private).
This type of procedure of diagnostic are often & unaffordable for patients. In those case the patients are depending on other medicinal system such as Unani/ Aurvedic system medication. In severe, case, when the patient have to go for upazilla health complex.(National Health Accounts (2003).

Description of Upazila Health Complex:
Upazila Health Complex (UHC) consists of both in- and out-patient services and care facilities. Most commonly, they have in-patient care support with 31 beds, while some UHC have over 50 beds. Some UHCs have an additional in-patient department, named Mother & Child Ward.
120 patients (50 in patients & 70 out patients) were randomly selected from Muktagachha Upazila Health Complex, Mymensingh and also all the physicians (9) from that same health complex.
Data mainly collected from two groups: patients and physicians.
Interviews were taken during November (2008) to February (2009), using a structured questionnaire consisting of total of 20 questions for the patients regarding their problems for which they came to the health complex, the questions were-
Is it the first time you have come to the doctor?
Who advised you to come to the doctor?
Why you have come to the doctor? Which antibiotic do you take and why?
Do you get from the hospital?
Do you pay for it?
How frequently you get it?
If you don’t get it from the hospital then how do you get it?

Do you take the same brand always?
If not, how do you change the brand?
Do you buy the full course at a time or part by part?
When do you stop taking medicines?
Do you stop taking medicines?
Do you take Tab. /Cap. /Dry syrup /Inj. and why?
If you prefer Dry syrup how do you prepare it?
If you forget to take the next dose-what do you do?
Where do you store the medicines in your house?
When your required brand is not available who help you to get the alternative one?
Interviews were also taken from the physicians using 6 questions as follows:
When do you choose to prescribe an antibiotic?
Do you prescribe antibiotics in cold and fever before diagnostic tests?
Is there any correlation between antibiotic prescription and patient satisfaction?
Do patients complete the course of antibiotic therapy?
In case of empirical antibiotic therapy which group of antibiotic do you prefer most? Any reason behind your preference
What are the factors that play most significant role in antibiotic resistance?

Reasons behind Antibiotic Prescription:
One of the most important topic is when the physician are prescribing the antibiotics is it for the suspected infection, Confirmed infection or both.Among the 24 physicians 68% prescribed antibiotics for Suspected infection & 24% for Confirmed infection & 4% for both. Here is the Table & the Chart given the brief description.
Table 3.6. Reasons behind Antibiotic Prescription
|Suspected infection||Confirmed infection||Both|

Chart 3.6: Reasons behind Antibiotic Prescription
Antibiotics are the greatest contribution of the 20th century to therapeutics. Their advent changed the outlook of the Physician about the power drugs can have on diseases. They are one of the few curative drugs. Their importance is magnified in the developing countries, where infective disease predominate. As a class they are one of the most frequently used as well as misuses drugs. This study identified the pattern of treatment procedure, antibiotics resistance occurring in the patient treated with antibiotics.
From the statistical analysis & from bar diagram of the Physicians we can see that the use of antibiotics among the 25 practitioners 68% are prescribed antibiotics for suspected infection & 24% are prescribed antibiotics for confirmed infection & 4% of them prescribed for both. Again, from the statistical analysis & from the pie chart of the Patients we found that the percent of the patient complete the antibiotic course 95% among them maximum patients are in patient and educated one & course incomplete percent is 40%. Among the course completed person maximum patients are In patient and educated one & from the course incomplete percent maximum persons are Out patient & illiterate one Next, I have got a very real picture of the service upazilla health complex for giving the medicine from the hospital at free of cost. Where I found that only 40% of the patient are getting medicine from hospital & most of them are in patient & most of times they have to pay for it. Furthermore, the percent of purchasing antibiotics full course is only 30% rater than buying part by part. In terms of the disease the highest percentage goes to G.I.T. infection, R.I.T. infection & cold with fever respectively 51.85%, 40.74% & 40.74%.Bangladesh has made significant progress in recent times in many of its social development indicators particularly in health. So to continue this significant progress we need to use antibiotics rationally to stop antibiotics resistance & treatment failure.
The Role of the Public
It is ironical that in this age of information, many people in this country are unable to educate themselves about health matters. They are ill-informed about illnesses, about the fact that a common cold, for example, is caused by a virus and thus does not need to be treated with antibiotics. Children are frequently down with acute respiratory infections and many parents immediately think that their suffering child needs an antibiotic because they do not know that a majority of coughs and colds are viral in origin. Their ignorance is not just about the cause of the disease; it is also about the medicines that they consume. They may have heard of the term “antibiotic”, but often do not know that it is prescribed for an illness caused by bacteria; and they also do not know that it is meant to be taken for a fixed period of time. One may argue that only health professionals need to be educated about disease and medicines, but for health to be in truly preventive mode, a basic knowledge of diseases and drugs among patients would go a long way in ensuring appropriate treatment such as appropriate antibiotic use.
The Responsibility of Doctors
Doctors are often considered to be God and therefore when a doctor gives an antibiotic to a patient, it is taken without question. However, a doctor is often pressurised to give antibiotics for a variety of reasons. It could be due to the pressure of making a patient well as soon as possible, or the fear of losing patients to another doctor. Patients often demand powerful treatments, and then there is the industry pressure and incentive schemes, and, most importantly, the doctor`s own clinical judgment skills. To be fair, many doctors work with inadequate and unreliable investigational facilities. This may promote the use of combination antibiotics and defensive medicine.
Pharmacists` (C grade) and Chemists` Shops:
Chemists` shops, more popularly known as “medical shops”, are a dime a dozen in many towns and cities. Many of them are situated near doctors` clinics, but often, patients go directly to a chemist, narrate their symptoms and ask for medication. The pharmacist (C grade) gives his “diagnosis”, and most often prescribes antibiotics — without a doctor`s prescription, of course. The problem is further compounded by the fact that many shops are manned by people who may not have even passed secondary school. Business rather than science is their occupation and whatever a patient asks for is given.
The Pharmaceutical Industry:
Industry and medical representatives “push” irrational antibiotic use more than any other player. After all, money makes the world go round. It is common knowledge that health professionals get incentives for prescribing and dispensing particular brands of medicines. This is particularly true in the case of antibiotics, which are sold most widely in a country like Bangladesh that has multiple infectious diseases. The situation gets worse when more expensive and reserve antibiotics are promoted by medical representatives who pull out words and sentences from medical literature to convince the already beleaguered doctor that his patient deserves “the best”.
Games can also be played in other ways especially when companies want to avoid the patent trap. Molecules from the same class are promoted with the bait that they are better, less costly, and easily administered. Unfortunately this widespread use leads to cross-resistance with the older antibiotic which is often used as a reserve antibiotic for serious and life saving illnesses.
There are hardly any government regulations on antibiotic use in Bangladesh. Policies meant for implementation in hospitals are not strictly implemented. Neither are there sufficient penalties for irrationally prescribing an antibiotic. The Drug Controller`s office is understaffed and overworked with clinical trial approvals, quality assessments and documentation. Manpower for regulating misuse and overuse of drugs is thus minimal. Willpower, too, is negligible; it would be interesting to know how knowledgeable policy makers are about the consequences of inappropriate antibiotic use.
There are other players who may be contributing to a significant amount of inappropriate antibiotic use. Farmers overuse antibiotics for both animal and agricultural purposes. Though there are specific antibiotics for these uses, in practice, many antibiotics used for humans are used in animal husbandry and agriculture. This leads to cross-resistance for humans and consequently high resistance.
Complementary medicine specialists and quacks also use allopathic drugs, including antibiotics, although they have no expertise in their prescription. Though the law clearly states that properly trained professionals should use only the systems of medicine they are trained in, the reality is very different.
It is interesting to note the number of ethical issues tied in to inappropriate antibiotic use and rising antibiotic resistance. Unethical antibiotic use is a much bigger issue than AIDS and terrorism put together. The consequences can affect all of us and, in fact, we are already feeling its effects. To prevent this potentially disastrous situation, we can, as a society, ethically use antibiotics, thereby saving ourselves from total annihilation by bacteria and other microbes.
Finally, we can say that any kind of survey is beneficial for getting the real condition of any particular objective. In terms of health related survey it the most important matter because it is directly related to the life of the human being.
Here, from the above description we come to know a lot about the primary healthcare , primary healthcare facilities in Bangladesh ,antibiotics , antibiotics resistance , antibiotics recommended dose etc. which are very important matter our life.
The use of antibiotics is very common for any infectious disease caused by the microbs but it can be misused that can cause a severe consequence like antibiotics resistance & finally treat failure. So our objectives were to collect the information in what percentage antibiotics are misused & also create some awareness about the rational use of antibiotics in the people in the rural level.
It is rationale to use essential antibiotics at PHC level. But only 35% of patients received essential antibiotics, whereas 65% of patients used other antibiotics. The reason behind this statistics is that essential antibiotics are less efficient in comparison to other more efficacious antibiotics.
The essential antibiotics list was promulgated in 1982, which is not updated at all. As a result, more efficacious antibiotics are not included in this list. At UHC, the patients get essential antibiotics free of cost. Since 35% of patients received essential antibiotics without paying money, so there is a greater chance of course completion, which ensures the rational use of antibiotics. On the other hand, 65% of patients bought the other efficacious but costly antibiotics by themselves, so the patients have a tendency to leave the course as incomplete, which is irrational, and leads to antibiotics resistance. Some other factors are also responsible for irrational use which develop antibiotic resistance, such as lack of proper diagnostic facilities at UHC, which results in wrong selection of antibiotic, lack of trained health professional, ignorance of patient about antibiotics, pressure from the patients to prescribe broad spectrum antibiotics to get relief from disease promptly, drug seeking tendency of patients, which is responsible for overuse of antibiotics.
