Objective: To explore seasonal patterns of antibiotic prescribing for selected infectious disease complaints for children up-to 5 years and adults (>18 years) reporting to out patient clinics of two hospitals in Ujjain.
Methods: This was cross sectional study; during 15 months period from 15th November 2007 to 15th February 2009. It covered 4 seasons, 2 winters, one summer and one rainy season. First consultations of all patients for suspected infectious aetiology at outpatients of two hospitals (one for profit and other academic) were included. A diagnosis prescribing form was filled by the treating consultant for each patient irrespective of whether an antibiotic was prescribed or not. An average of 70% of available consultants participated. Each prescribed antibiotic was coded according to the WHO Collaborating Centre for Drug Statistics Methodology, ATC classification index with DDDs 2009. All DDDs were calculated/1000 patients/diagnosis (DDD/TPD). Stata 10.0 was used for appropriate statistical tests.
Results: Out of a total of 5,733 patients antibiotics were prescribed in 3,732 (66.3%). These prescriptions contained 13 antibiotics, with a mean of 1.28 antibiotics per prescription. Indications were respiratory tract infections (32.2%), vaginal discharge (26.3%), urinary tract infections (16.3%), skin and soft tissue infections (15%), diarrhoea (9.2%) and prophylaxis (1%). Quinolones were the commonest group prescribed. Antibiotic prescribing was 37% less in academic hospital (P < 0.001). Prescribing peaked in rainy season with 70% of patients prescribed antibiotics. The independent predictors of antibiotic prescribing were seasons (2nd winter > 1st winter), facility (for profit > academic), age groups (adults > children), education level (illiterate > more educated), productive cough at presentation, ear discharge, pneumonia and dysentery. The number of patients per diagnosis, prescription rate with commonest prescribed antibiotic group with DDDs/ TPD per group is shown in table.
Conclusions: Statistically significant association between antibiotic prescribing and seasons, for profit hospital, age groups, education level, symptom of productive cough at presentation, ear discharge, pneumonia and dysentery was found. High use of quinolones is a cause of concern.
