Introduction:
The administration of primary healthcare by the Bangladesh
Government is carried out through a suprisingly extensive infrratructure of
facilities within each of the 64 districts. The districts are divided
into 460 papila(sub districts) which are subdivided into unions. Each union
consists of approximately 25,000 people & health services are
directed by the Ministry of Health & Family Welfare (MOHFW). Since July
1998 calls for providing an essential service package (ESP) or a
Community based healthcare scheme to the entire population at four different
levels of delivery.(www.photius .com)
The Ministry of Health and Family Planning was responsible
for developing, coordinating, and implementing the national health and
mother-and-child health care programs. Population control also was within the
purview of the ministry. The government’s policy objectives in the health care
sector were to provide a minimum level of health care services for all,
primarily through the construction of health facilities in rural areas and the
training of health care workers. The strategy of universal health care by the
year 2000 had become accepted, and government efforts toward infrastructure
development included the widespread construction of rural hospitals,
dispensaries, and clinics for outpatient care. Program implementation, however,
was limited by severe financial constraints, insufficient program management
and supervision, personnel shortages, inadequate staff performance, and
insufficient numbers of buildings, equipment, and supplies. .(www.photius

Primary Health Care (PHC) has been chosen by the Government
of Bangladesh as the strategy to achieve the goals of “Health for all” which is
now being implemented as Revitalized Primary Health Care. So we need to have a holistic
and balanced approach to health workforce education and give more attention to
ensuring quality of medical education, especially in the rapidly growing
private sector.
Primary health care (PHC):
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.
Primary health care was accepted by the member countries of
WHO as the key to achieving the goal of Health for all. (American Journal of Public Health, 1884-1893.)
Elements of PHC:
E – education for
health
L – locally endemic disease
control E – expanded program of
immunization
M – maternal and child
health E – essential
drugs
N –
nutrition T – treatment of communicable disease
s-safe water and sanitation. (American Journal of Public Health,
1884-1893.)
Essential components of primary
health care (PHC)
Equitable distribution:
Health services must be shared equally by all people
irrespective of their ability to pay and all (rich or poor, urban or rural)
must have access to health services. Primary health care aims to address the
current imbalance in health care by shifting the centre of gravity from cities
where a majority of the health budget is spent to rural areas where a majority
of people live in most countries. (American Journal of Public Health,
1884-1893.)
Community participation:
There must be a continuing effort to secure meaningful
involvement of the community in the planning, implementation and maintenance of
health services, beside maximum reliance on local resources such as manpower,
money and materials. (American Journal of Public Health,
November, 94(11): 1884-1893.)
Intersect oral coordination:
Primary health care involves in addition to the health
sector, all related sectors and aspects of national and community development,
in particular agriculture, animal husbandry, food, industry, education,
housing, public works, communication and other sectors. (American Journal of Public
Health,1884-1893.)
Four Cornerstones in primary health
care:
Active community participation
Intra and Inter-sectoral linkages
Use of appropriate Technology
Support Mechanism made Available
(American Journal of Public
Health,1884-1893.)
Primary healthcare in Bangladesh:
The administration of primary healthcare by the Bangladesh
government is carried out through a surprisingly extensive infrastructure of
facilities within each of the 64 districts. The districts are divided into 460
upazillas (sub-district) which are subdivided into unions. Each union consists
of approximately 25,000 people and health services are directed by the Ministry
of Health and Family Welfare (MOHFW).The levels are: community out-reaches,
health and family welfare centers/rural dispensaries, upazila health complexes
as first referral system and district hospital as second referral system.
(Bangladesh Demographic & Health Survey,
2004)
Primary health care in Union-level:
A union-level health and family welfare center provided the
first contact between the people and the health care system and was the nucleus
of primary health care delivery. As of 1985 there were 341 functional
subdistrict health centers, 1,275 rural dispensaries (to be converted to
union-level health and family welfare centers), and 1,054 union-level health
and family welfare centers. The total number of hospital beds at the
subdistrict level and below was 8,100. (Bangladesh Demographic & Health Survey,
2004)
Primary healthcare in District
level:
District hospitals and some infectious-disease and
specialized hospitals constituted the second level of referral for health care.
In the mid-1980s, there were 14 general hospitals (with capacities ranging from
100 to 150 beds), 43 general district hospitals (50 beds each), 12 tuberculosis
hospitals (20 to 120 beds each), and 1 mental hospital (400 beds). Besides
these, there were thirty-eight urban outpatient clinics, forty-four tuberculosis
clinics, and twenty-three school health clinics. Ten medical college hospitals
and eight postgraduate specialized institutes with attached hospitals
constituted the third level of health care. (Bangladesh Demographic & Health Survey,
2004)
Status of Healthcare in Bangladesh:
In Bangladesh, the status of healthcare is similar to the one
of many developing countries: medical practitioners in Bangladesh often operate
in relative isolation, dealing with diverse health care needs. Worldwide there
is difficulty in retaining specialists in non-urban areas. (Ministry of
Local Government, Rural Development & Cooperatives,2005)

The Public Sector:
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. (National Health Accounts, 2003)
The Private Sector:
In the private sector, there are traditional healers
(Kabiraj, totka, and faith healers like pir / fakirs), homeopathic
practitioners, village doctors (rural medical practitioners RMPs/ Palli
Chikitsoks-PCs), community health workers (CHWs) and finally, retail drugstores
that sell allopathic medicine on demand.To this is added an emerging cadre of
semi-qualified community health workers / volunteers, who are formally trained
by the NGOs (such as BRAC, Gonoshasthya Kendra etc); their numbers have been
increasing since the 1990’s with the expansion of PHC infrastructure in the
country. (National Health Accounts,2003)

Problems in the healthcare system:
It is noted that the highest number of problems (22%) in
health sector are related to inadequate number of physicians, wrong treatment,
negligence towards patients, absence from duty and unwillingness of doctors to
stay at rural areas and small towns. The other problems are related to
supplies, equipment, beds etc (21%). Some other major problems often discussed
also include lack of ambulance services as well as proper referral services. ( National Health Accounts 2003)
Antibiotics:
Antibiotics may be informally defined as the sub-group of
anti-infectives that are derived from bacterial sources and are used to treat
bacterial infections. Other classes of drugs, most notably the sulfonamides,
may be effective antibacterials. Similarly, some antibiotics may have secondary
uses, such as the use of demeclocycline (Declomycin, a tetracycline derivative)
to treat the syndrome of inappropriate antidiuretic hormone (SIADH) secretion.
Other antibiotics may be useful in treating protozoal infections. (Scott, Geoffrey, 2004.)
Microorganisms are very diverse. They include bacteria,
fungi, archaea, and protists; microscopic plants (called green algae); and
animals such as plankton, the planarian and the amoeba. Some also include
viruses, but others consider these as non-living. Most microorganisms are
unicellular (or single-celled), but this is not universal, since some
multicellular organisms are microscopic, while some unicellular protists and
bacteria, like Thiomargarita namibiensis, are macroscopic visible to the naked
eye. (Scott, Geoffrey,2004)

(Crueger, W. Biotechnology,1989.)
The main groups of antibiotics
briefly described below:
Although there are several classification schemes for
antibiotics, based on bacterial spectrum (broad versus narrow) or route of
administration (injectable versus oral versus topical), or type of activity
(bactericidal vs. bacteriostatic), the most useful is based on chemical
structure. Antibiotics within a structural class will generally show similar
patterns of effectiveness, toxicity, and allergic potential. (Crueger, W.Biotechnology,1989.)
Penicillins:
The penicillins are the oldest class of antibiotics, and have
a common chemical structure which they share with the cephalopsorins. The two
groups are classed as the beta-lactam antibiotics, and are generally
bacteriocidal—that is, they kill bacteria rather than inhibiting growth. The
penicillins can be further subdivided. The natural pencillins are based on the
original penicillin G structure; penicillinase-resistant penicillins, notably
methicillin and oxacillin, are active even in the presence of the bacterial enzyme
that inactivates most natural penicillins. (Crueger, W. Biotechnology,1989.)
Cephalosporins:
Cephalosporins and the closely related cephamycins and
carbapenems, like the pencillins, contain a beta-lactam chemical structure.
Consequently, there are patterns of cross-resistance and cross-allergenicity
among the drugs in these classes. The “cepha” drugs are among the most diverse
classes of antibiotics, and are themselves subgrouped into 1st, 2nd and 3rd
generations. Each generation has a broader spectrum of activity than the one
before. In addition, cefoxitin, a cephamycin, is highly active against
anaerobic bacteria, which offers utility in treatment of abdominal infections.
The 3rd generation drugs, cefotaxime, ceftizoxime, ceftriaxone and others, cross
the blood-brain barrier and may be used to treat meningitis and encephalitis.
Cephalopsorins are the usually preferred agents for surgical prophylaxis. (Crueger, W. Biotechnology,1989.)
Fluroquinolones:
The fluroquinolones are synthetic antibacterial agents, and
not derived from bacteria. They are included here because they can be readily
interchanged with traditional antibiotics. An earlier, related class of
antibacterial agents, the quinolones, were not well absorbed, and could be used
only to treat urinary tract infections. The fluroquinolones, which are based on
the older group, are broad-spectrum bacteriocidal drugs that are chemically
unrelated to the penicillins or the cephaloprosins. (Crueger, W. Biotechnology,1989.)
Tetracyclines:
Tetracyclines got their name because they share a chemical
structure that has four rings. They are derived from a species of Streptomyces
bacteria. Broad-spectrum bacteriostatic agents, the tetracyclines may be
effective against a wide variety of microorganisms, including rickettsia and
amebic parasites. (Crueger, W.Biotechnology,1989.)
Macrolide:
The macrolide antibiotics are derived from Streptomyces
bacteria, and got their name because they all have a macrocyclic lactone
chemical structure. Erythromycin, the prototype of this class, has a spectrum
and use similar to penicillin. Newer members of the group, azithromycin and
clarithyromycin, are particularly useful for their high level of lung
penetration. Clarithromycin has been widely used to treat Helicobacter pylori
infections, the cause of stomach ulcers. (Crueger, W. Biotechnology,1989.)
Others:
Other classes of antibiotics include the aminoglycosides,
which are particularly useful for their effectiveness in treating Pseudomonas
aeruginosa infections; the lincosamindes, clindamycin and lincomycin, which are
highly active against anaerobic pathogens. There are other, individual drugs
which may have utility in specific infections. (Crueger, W. Biotechnology,1989.)

Recommended Dosage:
Dosages of antibiotics depend on the individual, the
infection that is being treated, and the presence of other medical conditions. For
children, the dosage usually is based on body weight and is lower than the
adult dosage. To be effective, an entire treatment with antibiotics must be
completed, even if the symptoms of infection have disappeared. Furthermore, it
is important to keep the level of antibiotic in the body at a constant level
during treatment. Therefore, the drug should be taken on a regular schedule. If
a dose is missed, it should be taken as soon as possible. If it is almost time
for the next dose, the missed dose should be skipped. Doubling up doses is
generally not recommended.
(Encyclopedia of Public Health,
2002)
Average adult dosages of common
antibiotics for cancer patients are as follows:
Cefepime: 500 mg to 2 gm, injected into a
vein or muscle, every 8–12 hours for 7–10 days.
Ceftazidime: 250 mg to 2 gm, injected into a
vein or muscle, every 8–12 hours.
Ceftriaxone: 1–2 gm, injected into a vein or
muscle, every 24 hours.
Ciprofloxacin: 500–750 mg of the tablet or
suspension, every 12 hours, for 3–28 days, taken two hours after meals with 8
oz of water; bone and joint infections usually are treated for at least 4–6
weeks; 200–400 mg injected every 8–12 hours.
Metronidazole: for bacterial infections, 7.5 mg per
kg (3.4 mg per lb) of body weight up to a maximum of 1 gm, every six hours for
at least seven days (capsules or tablets); 15 mg per kg (6.8 mg per lb) for the
first dose, followed by half that dosage every six hours for at least seven
days (injected into a vein); for protozoal infections caused by amebas, 500–750
mg of oral medicine, three times per day for 5–10 days; for trichomoniasis, 2
gm for one day or 250 mg three times per day for seven days (oral medicine);
extended-release tablets for vaginal bacterial infections, 750 mg once a day
for seven days.

2002)
Side Effects:
Side effects related to particular
antibiotics
All antibiotics cause risk of overgrowth by non-susceptible
bacteria. Manufacturers list other major hazards by class; however, the health
care provider should review each drug individually to assess the degree of
risk.
Penicillins: Hypersensitivity may be common, and
cross allergenicity with cephalosporins has been reported. Penicillins are
classed as category B during pregnancy. ( Moellering, R. C., Jr.
“Linezolid.” 2003)
Cephalosporins: Several cephalosporins and related
compounds have been associated with seizures. Cefmetazole, cefoperazone,
cefotetan and ceftriaxone may be associated with a fall in prothrombin activity
and coagulation abnormalities. ( Moellering, R. C., Jr.
“Linezolid.” 2003)
Fluoroquinolones: Lomefloxacin has been associated
with increased photosensitivity. All drugs in this class have been associated
with convulsions. (Moellering, R. C., Jr. “Linezolid.” 2003)
Tetracyclines: Demeclocycline may cause increased
photosensitivity. Minocycline may cause dizziness. Children under the age of
eight should not use tetracyclines, and specifically during periods of tooth
development. Oral tetracyclines bind to anions such as calcium and iron. (Moellering, R. C., Jr. “Linezolid.”
2003)
Macrolides: Erythromycin may aggravate the
weakness of patients with myasthenia gravis. Azithromycin has, rarely, been
associated with allergic reactions, including angioedema, anaphylaxis, and
dermatologic reactions, including Stevens-Johnson syndrome and toxic epidermal
necrolysis. (Moellering, R. C., Jr. “Linezolid.” 2003)
Aminoglycosides: This class of drugs causes kidney
and hearing problems. These problems can occur even with normal doses. (Moellering, R. C., Jr. “Linezolid.”
2003)
Side Effects related to
indiduals:
Some individuals may have allergic reactions to antibiotics.
If symptoms of an allergic reaction (such as rash, shortness of breath,
swelling of the face and neck), severe diarrhea, or abdominal cramping occur,
the antibiotic should be stopped and the individual should seek medical advice.
Because antibiotics can affect bacteria that are beneficial,
as well as those that are harmful, women may become susceptible to infections
by fungi when taking antibiotics. Vaginal itching or discharge may be symptoms
of such infections. All patients may develop oral fungal infections of the
mouth, indicated by white plaques in the mouth.
Injected antibiotics may result in irritation, pain,
tenderness, or swelling in the vein used for injection. Antibiotics used in
cancer patients may have numerous side effects, both minor and severe; however,
most side effects are uncommon or rare. (Moellering, R. C., Jr. “Linezolid.”
2003)
Interactions:
Use of all antibiotics may temporarily reduce the
effectiveness of birth control pills; alternative birth control methods should
be used while taking these medications.
Antacids should be avoided while on tetracyclines as the
calcium can impair absorption of this antibiotic class. For this reason,
tetracyclines should not be taken just before or after consuming foods rich in
calcium or iron. Consult specialized references for additional interactions to
specific antibiotics. (Ronning M, et al,2003)
Rationale use of Antibiotics:
The Main basis is “SANE”
S Specificity
A Availability
N Need to the community
E Efficacy
Rationale drug use ( RDU ) is conventionally defined as the
use of an appropriate, efficacious, safe and cost-effective drug given for the
right indication in the right dose and formulation, at right intervals and for
the right duration of time. The promotion of rationale antibiotic use involves
a wide range of activities such as the adaptation of the essential drug
concept, training of health professionals about rationale antibiotic use and
development of evidence-based clinical guidelines. (Williams J D,1986)
The following guidelines will ensure that antibiotics are
used in a way which minimizes the emergence and spread of resistant organisms,
and which maximizes their efficacy and safety.Use antibiotics only when
indicated. Viral and self-limiting bacterial disease does not benefit from the
use of antibiotics .Appropriate, specimens for Gram stain, culture and
sensitivity testing should be obtained before commencing antibiotic therapy.
The choice of agent should be based on factors such as spectrum of activity in
relation to the known or suspected causative organism, safety, previous
clinical response, cost, ease of use and the potential for selection of
resistant organisms. An adequate dose and duration of treatment is essential
for all antibiotic therapy.A history of allergy or other adverse effect to the
drug under consideration should always be sought Prophylactic use of
antibiotics should be restricted. Empirical antibiotic therapy should be based
on local epidemiological data on potential pathogens and their patterns of
sensitivity. (Williams J D,1986)
Issues of Antibiotics Resistance:
The emergence and spread of antimicrobial resistance are
complex problems driven by numerous interconnected factors, many of which are
linked to the misuse of antimicrobials and thus amenable to change. In turn,
antimicrobial use is influenced by an interplay of the knowledge, expectations,
and interactions of prescribers and patients, economic incentives,
characteristics of a country’s health system, and the regulatory environment. (Soulsby EJ
,2005).
Factors that encourage the spread of
resistance are following :
Patient-related:
Patient-related factors are major drivers of inappropriate
antimicrobial use. For example, many patients believe that new and expensive
medications are more efficacious than older agents. In addition to causing
unnecessary health care expenditure, this perception encourages the selection
of resistance to these newer agents as well as to older agents in their class. (Soulsby EJ
,2005).
Self-medication:
Self-medication with antimicrobials is another major
factor contributing to resistance. Self-medicated antimicrobials may be
unnecessary, are often inadequately dosed, or may not contain adequate amounts
of active drug, especially if they are counterfeit drugs. (Soulsby EJ
,2005).
Prescribers’ perceptions:
Prescribers’ perceptions regarding patient expectations
and demands substantially influence prescribing practice. Physicians can be
pressured by patient expectations to prescribe antimicrobials even in the
absence of appropriate indications. (Soulsby EJ
,2005).
Patient compliance:
Patient compliance with recommended treatment is another
major problem. Patients forget to take medication, interrupt their treatment
when they begin to feel better, or may be unable to afford a full course,
thereby creating an ideal environment for microbes to adapt rather than be
killed. (Soulsby EJ ,2005).
Hospitals are a critical component:
Hospitals are a critical component the antimicrobial resistance
problem worldwide. The combination of highly susceptible patients, intensive
and prolonged antimicrobial use, and cross-infection has resulted in nosocomial
infections with highly resistant bacterial pathogens. Resistant
hospital-acquired infections are expensive to control and extremely difficult
to eradicate. (Soulsby EJ ,2005).
Aim / Rationale of the work:
The main aim of that survey is to see whether the antibiotics
are administered rationally or not in the upazilla level of Bangladesh. The purpose
of this study was to analyze a subset of data concerning Rational use of
Antibiotics in Bangladesh obtained from the currently ongoing research project.
First, a comprehensive review of the literature was
undertaken with the primary purpose of collecting literature pertinent to
education and prevention programmes focusing on Antibiotics abuses.
Second, the survey was administered through a series of
interviews which were part of the study to collect perceptions and
recommendations of mate Antibiotics users.
Thirdly, if we want to get an overview of the rational use of
antibiotics than at first we need to pick out the picture of the ground level
like the upazilla level of Bangladesh than we can get an idea about the level
of antibiotic use in Bangladesh.
Again, we can say that, there is a good relationship with the
common term Education & the Rational use of the antibiotics because
an educated person is more aware of his health & the severity of the
irrational use of antibiotics than the illiterate person & the ratio
of uneducated person is higher than the district & the division level.
This prospective, study necessary to determine the
feasibility of determining the risk of abuses of Antibiotics in
Bangladesh.
We can also said that the aim of this survey was to find out
the possible causes of antibiotic resistance & treatment failure due to
wrong prescription.

Group of Antibiotics Prescribed:
During this survey I collected this data, where I found
that 33.33% of the physician prescribed Fluroquinolone group is the
highest in percentage & the lowest in percentage is Chloramphenicol
is about 5.1851% & the other percentages are given in the table.

This is the very important factor in
the survey is whether the patient complete the course or not.Here I found that
95% were complet the course & 40% weren’t. Among the 95% maximum patient
were In Patient.

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 of it.

Reasons behind Antibiotic Prescription
Discussion:
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.
Conclusion:
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.
