Background And AimsCoronary heart disease (CHD) is the leading cause of death in India resulting in loss of young Indians. Statins have proved to reduce the CHD mortality in various clinical trials. The aim of the study is to find the cost-effectiveness ratio (CER) for each major coronary event averted and a coronary death avoided by use of statins in different clinical settings based on the data from the major clinical trials on statins.Materials And MethodsUsing electronic database and as per our inclusion and exclusion criteria we selected the West of Scotland Coronary Prevention Study (WOSCOPS), the Air Force Coronary Atherosclerosis Prevention Study (AFCAPS) and the Anglo-Scandinavian Cardiac Outcomes Trial--Lipid Lowering Arm (ASCOT-LLA) study for primary prevention; the Cholesterol and Recurrent Events Trial (CARE), the Long-term Intervention with Pravastatin in Ischemic Disease (LIPID) Study and the Scandinavian Simvastatin Survival Study (4S) for secondary prevention and two studies, the Heart Protection Study (HPS) and the Pravastatin in elderly individuals at risk of vascular disease (PROSPER) study for high-risk patients. The results of these studies were used for cost-effectiveness analysis of statins in different patient groups.Statistical AnalysisAbsolute risk reduction, Number Needed to Benefit (NNTB), NNTB/year for total sample and in subgroups of males, females and age >65 was derived. CER for branded and generic versions was calculated by using the prices of statins listed in Indian Drug Review Triple i.ResultsCost-effectiveness ratio (CER) in primary prevention studies i.e., the WOSCOPS, the AFCAPS and the ASCOT-LLA was Rs. 25.8 lacs, Rs. 23.8 lacs and Rs. 7.9 lacs per major coronary event averted respectively. CER in secondary prevention studies i.e., the CARE and the LIPID was approximately Rs. 20 lacs per major coronary event averted while it was Rs. 52.4 lacs and Rs. 37 lacs per coronary heart disease (CHD) death avoided. CER from the 4S was Rs. 6.9 lacs per major coronary event and Rs. 16.9 lacs per CHD death averted. CER in the HPS and the PROSPER study was Rs. 17.9 lacs and Rs. 27.1 lacs per major coronary event avoided in high-risk patients.ConclusionCost associated with the use of statins is higher in primary prevention as compared to secondary prevention. More studies are needed to confirm the cost-effectiveness of statins to make any decision for health policy.
