Impact assessment of pharmacist-supervised intervention on health-related quality of life of newly diagnosed diabetics: A pre-post design

Abstract

Introduction: Diabetics face a series of challenges that affect all aspects of their daily life. Diabetes related complications adversely affect patient's health-related quality of life (HRQoL). Knowledge and self-care skills of diabetics are corner stones to improve their HRQoL. Objective: To assess the impact of pharmacist-supervised intervention on HRQoL of newly diagnosed diabetics using an Audit of Diabetes-Dependent Quality of Life (ADDQoL) questionnaire. Materials and Methods: A pre-post comparison study was conducted among the control group (CG), test 1 group (T1G) and test 2 group (T2G) patients with three treatment arms to explore the impact of pharmacist-supervised intervention on HRQoL of newly diagnosed diabetics for 18 months. Patients' HRQoL scores were determined using ADDQoL questionnaire at baseline, 3, 6, 9 and 12-months. T1G patients received pharmacist's intervention whereas T2G patients received diabetic kit demonstration in addition to pharmacist's intervention. CG patients were deprived of pharmacist intervention and diabetic kit demonstration, and only received care from attending physician/nurses. Non-parametric tests were used to find the differences in an average weighted impact scores (AWIS) among the groups before and after the intervention at P ? 0.05. Results: Friedman test identified significant (P 0.001) improvement in AWIS among the test groups' patients. Differences in scores were significant between T1G and T2G at 6-months (P = 0.033), 9-months (P 0.001) and 12-months (P 0.001); between CG and T1G at 12-months (P 0.001) and between CG and T2G at 9-months (P 0.001) and 12-months (P 0.0010) on Mann.Whitney U test. Conclusion: Pharmacist's intervention improved AWIS of test groups' diabetics. Diabetic kit demonstration strengthened the disease understanding and selfcare skills of T2G patients. Disease and self-care awareness among diabetics should be increased in Nepali healthcare system by involving pharmacists for better patient's related outcomes.
