Managing comorbidities in Covid-19 patients: A drug utilization study in a COVID-dedicated hospital in Northern India

INTRODUCTION: In the prevailing COVID-19 pandemic, the Indian healthcare system has worked hard towards restricting the adverse outcomes to the least possible figures. The present study aims to share the experience of a COVID-dedicated tertiary care government hospital in Northern India of managing COVID-19 patients with comorbidities. METHODOLOGY: A retrospective, observational study was conducted in a COVID-dedicated tertiary health care government hospital in Northern India. Details on sociodemographic data, hospital admission data, and drug utilization pattern of all laboratory-confirmed COVID-19 patients of all age groups, either gender, having comorbidity (s), and admitted between April and September, 2020 were noted and evaluated. RESULTS: Among the total study participants (N = 406), 2868 drugs were prescribed. Out of these, 2336 were used for the management of symptoms of COVID-19 and 532 were used for the management of coexistent comorbidity (s). For COVID-19 symptoms, the most commonly prescribed class of drugs were antimicrobials (853, 36.52%), followed by nonsteroidal antiinflammatory drugs (374, 16.01%), proton pump inhibitors (299, 12.80%), antihistamines (232, 9.93%), immunosuppressant drugs (103, 4.41%), and others. For comorbidities most commonly prescribed were antihypertensive (310, 58.60%) drugs, followed by antidiabetic drugs (166, 31.38%), bronchodilators (34, 6.43%), thyroid hormones (11, 2.08%), immunosuppressant drugs (7, 1.32%). CONCLUSION: The most frequently prescribed antihypertensives were calcium channel blockers (CCBs) and least prescribed was beta blocker+CCB. Among the antidiabetic drugs, most frequently prescribed was insulin and least prescribed was DPP-4 inhibitors and Biguanide+DPP-4 inhibitor both.
