Abstract

Introduction: Parenteral antibiotic (PA) prescription pattern in a hospital will directly influence the annual budget allocation, development of bacterial resistance and occurrence of unnecessary adverse drug reactions if it is done with poor adherence to the standard guidelines of prescription. As specialist in the field we understand the need of conducting economic studies in relation to the cost and utility of PA prescription pattern. It will be helpful to predict the drug procurement plan for the next year and also to prevent unnecessary complications mentioned above. Objective: Our main objective was to analyze the cost/utility relationship of PA drugs which were used in medical wards in this hospital according to the top ten of the cost (TTTC) and the top ten of the consumption (TTCS). Materials and method : Aggregate data from the pharmacy record books were collected for year 2010 from indoor pharmacy. Unit prize was obtained from medical supplies division. Total quantity consumed by each medical ward was considered for analysis of the cost /utility relationship. Two top ten lists were prepared according to the cost and the consumption respectively for medical wards and the correlation was analyzed using non parametric testing with spearman test. Results: Regarding PA drugs used in this hospital, 7/10 PA drugs in TTTC are not included in the TTCS. Out of the total cost for TTTC, 82.6% of the cost had been spent for the PA drugs which are not in the TTCS and 17.5% of the cost of TTTC was used to purchase only three drugs from the TTCS. But these three drugs had contributed only 28% of top ten consumption. 72% of the PA drugs in TTCS were not costly drugs and highly consumed in medical wards. Correlation was significantly positive between cost and utility of PA drugs. ( r=-0.91,p<0.001) Conclusion: Majority of the consumed PA drugs are non-costly and it indicates the prescriptions had been done according to the rational guidelines including cost, availability and affordability. Correlation further confirms that majority of the PA consumption was low costly drugs. As most of the money had been spent to purchase highly expensive PA drugs for medical wards we suggest to review the clinical indications for these drugs with the microbiological evidence to be compatible with the allocated health budget for the hospital. This further suggests conducting the cost effective economic studies to evaluate the suitable drug alternatives for such indications.
