Objective: To determine the quality of prescribing in hypertension in primary and secondary health care settings using the Prescription Quality Index (PQI) tool and to assess the reliability of this tool. Materials and Methods: An observational cross-sectional study was carried out for 6 months in order to assess quality of prescribing of antihypertensive drugs using Prescription Quality Index (PQI) at four primary (PHC) and two secondary (SHC) health care facilities. Patients attending these facilities for at least 3 months were included. Complete medical history and prescriptions received were noted. Total and criteria wise PQI scores were derived for each prescription. Prescriptions were categorized as poor (score of ≤31), medium (score 32-33) and high quality (score 34-43) based on PQI total score. Psychometric analysis using factor analysis was carried out to assess reliability and validity. Results: Total 73 hypertensive patients were included. Mean age was 61.2 ± 11 years with 35 (48%) patients above 65 years of age. Total PQI score was 26 ± 11. There was a significant difference in PQI score between PHC and SHC (P < 0.05) Out of 73 prescriptions, 43 (59%) were of poor quality with PQI score <31. The value of Cronbach's α for the entire 22 criteria of PQI was 0.71 suggesting good reliability of PQI tool in our setting. Conclusions: Based on PQI scores, quality of prescribing in hypertensive patients was poor, somewhat better in primary as compared to secondary health care facility. PQI is reliable for measuring prescribing quality in hypertension in Indian set up.
