Abstract
With a handsome sample, specialists, general practitioners and Quacks both male and female from Faisalabad district of the province of Punjab, Pakistan, were approached for the study. A self-administered questionnaire was designed for the purpose. Factors to prescribe an antibiotic and the reasons for the attitude to prescribe a broad-spectrum antibiotic were elicited. Suggestions regarding prudent use of antibiotics were also collected from the prescribers. According to the answers, the prescribers of City Area are more rational as compared to the Semi-Urban or Rural Area in all the specialties including, Infants, Pregnant/Lactating Mothers, Hepatic and Renal Impairment. This is perhaps due to lack of fresh knowledge and less experience in the respective field. On the other hand, as we go from highly educated prescribers to less qualified doctors or Non-doctors (Quacks), the use of antibiotic become less rational or irrational. It is obvious from the results that the use of antibiotics is irrational or less rational. It also means that antibiotics are misused by the prescribers, which results in the antibiotic resistant emergence of bacterial strains. So, the antibiotic use must be in accordance with the current guidelines by the leading health providing institutions. However, the highly qualified doctors are using antibiotics more rationally as compared to less qualified doctors or non- doctors eg., quacks and LHVs.

Introduction
Antibiotics are natural or synthetic substances that have ability either to destroy micro-organisms or to inhibit their growth. Antibiotics are extensively used to treat infectious diseases of humans, plants and animals [1].
While prescribing antibiotics, factors related to the patient which must be considered include history of allergy, renal and hepatic function, susceptibility to infection (i.e. whether immune-compromised), ability to tolerate drugs by mouth, severity of illness, ethnic origin, age, whether taking other medication and, if female, whether pregnant, breast-feeding or taking an oral contraceptive, renal and hepatic impairment. The known or likely organism and its antibacterial sensitivity, in association with the above factors, will suggest one or more antibiotics; the final choice is made depending on the microbiological, pharmacological, and toxicological properties of that / those antibiotic(s) [2].
The antibiotics when prescribed to the above mentioned criteria can say that they are used appropriately or rationally. Buetow defined appropriateness as "The outcome of a process of decision making that emphasizes/maximizes net individual health gains within society's available resources". It means, appropriateness is the outcome when the patient receives the "right" drug, regardless the grounds on which the prescribing decision is based. The outcome here means the immediate outcome of the prescribing decision, i.e. the prescription, rather than longer-term outcomes for the patient [3].
Emergence of drug-resistant pathogens is a growing issue to world’s population regardless of age, gender, or socioeconomic background. They endanger people not only in industrial societies like the United States, United Kingdom and other developed countries but in less developed nations as well [4].
Okeke et al. [5] depicted that there are multiple factors contributing to resistance problem in developing countries around the world.
These factors include:
o Chaotic and widespread use of antimicrobials for community-acquired infections,
o Self-medication [5]
o Over the counter availability of antibiotics [7]
In developing countries the situation of drug irrational use is particularly alarming. In Pakistan, the average number of drugs per prescription was 3.5; with antibiotics accounting for 76% of the prescribed drugs [8].
For this reason purpose of this study was to identify and evaluate factors influencing prevalent attitudes and practices of prescribers regarding antibiotic usage in Infants.
Materials and Methods
The questionnaire was designed keeping in view all these specialties regarding the antibiotic use by the prescribers. After getting the data by providing a self-administered, anonymous questionnaire to the health care providers, it was divided into two striatums;
o Area
o Qualification
In all the studies, questions from basically two aspects were asked from the participants;
o General Knowledge about the Antibiotic use in the respective field
o Situations where broad spectrum antibiotics are being used instead of narrow spectrum antibiotics
Another aspect which was kept in mind while designing questionnaire is that if the answer of a question is Yes or No, it will be rational or irrational depending on the type of question. In Infants questionnaire, the antibiotic use will be rational if the answer of the following questions is 'Yes'
o Do you agree with the opinion that in infants none of the antibiotic would be safest one?
o Do you think that Kernicterus is an important consideration while prescribing antibiotic in infants?
o To treat the infections in infants, a best approach is to use a narrow spectrum antibiotic with highest efficacy
o According to your opinion, in infants, use of antibiotics having wide therapeutic index should be encouraged
o Do you agree that culture and sensitivity report must be done before using antibiotics in infants?
o Do you agree that the development of antibiogram can be helpful to use antibiotics prudently in infants?
And the antibiotic use will be rational if the answer of the following questions is 'No'
o Do you think that sulphonamides (Trimethoprim, Sulfamethoxazole etc.) are the safest drugs to treat UTI in infants?
o In infants would you prefer tetracyclines as a group of broad spectrum antibiotics?
o Do you agree with the opinion that amino glycosides are the drugs of choice in infants?
o To treat the infections in infants, a best approach is to use a broad spectrum antibiotic with highest efficacy
o Usually Fluoroquinolones are used to treat LRTI in infants. Should their use be strongly recommended?
o Do you agree with the opinion that the use of more than one narrow spectrum antibiotics would be preferred over a single broad spectrum antibiotic?
The survey was done with a self-designed questionnaire eliciting the factors influencing the decision of the prescribers while prescribing antimicrobials. The participants included Non-Specialists, e.g. General Practitioners (having MBBS degree), quacks, Lady Health Visitors (LHVs) and Specialists, e.g Medical, surgical, obstetrics/gynecology, pediatricsetc having postgraduate degrees or diplomas in their field). The survey was carried out in Faisalabad districts, of the Province of Punjab, Pakistan (8 towns, both urban and semi-urban areas) and rural areas adjoining the Faisalabad). The whole city is covered by about 2500 registered medical practitioners. The study was conducted from September 2009 to September 2010. The sampling of the participants was a simple and determined by approaching the participants individually and requested them to answer the questionnaire. The study was approved by the Board of Scientific Studies, University of Sargodha, Sargodha. The questionnaire used, was the modified version of that used by the Alliance for the Prudent Use of Antibiotics in cooperation with the Massachusetts Infectious Disease Society and the Massachusetts Department of Public Health.
Questions in the questionnaire are basically designed keeping in view the factors which can help in deriving the results at the end of the study. It contains basic details like specialty based questions about the usage of antibiotics in Infants. Also include factors like (Educational status, and Area of practice place), questions pertaining to the factors involved in the decision making to prescribe an antibiotic (like fever, purulent discharge, patient request, colleague's opinion etc) and factors responsible for the attitude to prescribe a broad-spectrum antibiotic while a narrow spectrum would suffice. Apart from that, the three most common infections practitioners often treat, the three most common antibiotics they prescribe, and the conditions in which they use the antibiogram facility were also elicited. Finally, they were asked to give suggestions on ways and means to use antibiotics prudently in specialties like Infants.
Besides this, main factors which kept into focus while making the questionnaire in general were (Table 1):
Other factors, where broad spectrum antibiotic is used instead of narrow spectrum were as follows (Table 2):
The language of the questionnaire was English, and the time for answering it was approx 30 minutes. All the data were entered in a Microsoft Excel spreadsheet and rechecked by 2 independent persons for any errors.
There are four major groups upon which questionnaire were formulated to carry out the study. While making the questionnaire, questions were designed such that, if the answer of a particular question is Yes/No, it will be considered rational or irrational depending on the type of the question. The questionnaires are as follows:

Discussion
According to results obtained from the prescribers of City area and Semi-urban or Rural area (STRIATUM # 1, Group 1, Area Based Striatum), the prescribers of City Area are more rational as compared to Semi-Urban or Rural Area regarding general antibiotic use.
According to the answers of the questions of (STRIATUM#1, Group 2, Area Based Striatum), the prescribers of the city area are more rational as compared to the Semi-urban or rural area.
In the (STRIATUM # 2, Group 1, Qualification Based Striatum), as we go from highly educated and experienced prescribers to less educated prescribers or layman, the antibiotic use become injudicious i-e, irrational.
In the (STRIATUM # 2, Group 2, Qualification Based Striatum), same is the case as of group 1 answers, i.e., less educated prescribers and non-qualified doctors are using antibiotic irrationally than highly qualified specialist doctors.
The prescribers diagnose Diarrhoea, Pharyngitis and Pneumonia as most common infections prevalent in Infants. Besides these, according to some prescribers, Otitis media, Sinusitis and Urinary Tract Infections are also prevalent in Infants. The three most commonly used antibiotics in Infants are Ceftazidime, Amikacin and Ampicillin. Other antibiotics which are also used frequently to treat infection in Infants are Gentamicin, Cefixime, Amoxycillin, Ceftriaxone and Cefuroxime. Body Weight,is the best criteria for dose calculation in Infants [1].
Regarding safest broad spectrum antibiotic in infants, prescribers use Amoxycillin, Cefuroxime, Ceftriaxone and Cefixime. That is, they Consider penicillins and Cephalosporins to be safe in Infants. However, studies suggest that penicillins are safe for use in infants [9,10] whereas, cephalosporins have severe side effects especially when used with calcium and also cause Kernicterus in newborns so should be used with caution in neonates especially when used in combination with calcium e.g, concomitant therapy of Ceftriaxone and Calcium is contraindicated in infants [11].
Some suggestions from prescribers were also asked regarding prudent use of antibiotics. According to them, proper investigation and diagnosis [12], improved antibiotic knowledge and awareness, rapid culture and sensitivity test, crack down of Quacks, reduction in the nosocomial infection by improving sterilization in the hospitals and by restricting the over-the- counter sales of the antibiotics are important factors for the judicious and safe use of the antibiotics.
Conclusion
It is clear from the above discussion that lack of true diagnosis, antibiotic resistance and purulent discharge are the major influential factors to prescribe broad spectrum antibiotics instead of narrow spectrum. Moreover, lack of an antibiogram facility, patient pressure/satisfaction and lack of rapid culture and sensitivity test facility, lack of proper investigation and diagnosis, also contributes to prescribe broad spectrum antibiotics where narrow spectrum antibiotics can be used. Is was also come into notice that antibiotics, which are a special group of medicine and must be handled with extreme care, are being used by quacks and LHVs, who are not expert to prescribe medicine, especially antibiotics. There must be evidence based use of antibiotics. Almost all the prescribers are convinced on the fact that there must be improved sterilization in the hospital to avoid nosocomial infections. This would extremely helpful in reducing the antibiotic usage and also antibiotic resistance in the hospitals and would also reduce the stay of the patient in the hospital and also the medication cost and others costs. Improved antibiotic knowledge and patient awareness, ensuring complete cure while using an antibiotic is also necessary for prudent use of antibiotics.
