Retrospective Study on Prescription Pattern on the Management of Chronic Obstructive Pulmonary Disease (COPD)

Background: COPD is a disease caused by chronic bronchitis, emphysema, or combination of both conditions. As per the Global Burden of Disease 2017 prediction, COPD is the second leading cause of death in Nepal, the fourth leading cause of premature death and the third cause for disability-adjusted life years (DALYs) in Nepal. The prevalence of COPD in Nepal was 11.7%. If current situation prevails, the burden of COPD might increase continuously in the nation. Hence, the findings from this study might provide baseline information to medical and paramedical students and other researchers to conduct further study in similar area.

Objectives: The study was done to assess the prescription pattern for management of COPD in multispecialty hospital of Nepal.

Method: A retrospective study was conducted at 100 bedded multispecialty hospital located at Lalitpur, Nepal. A total of 200 inpatient records, from Baishak 2075 to Chaitra 2078 were reviewed and data was collected as per the objectives and analysed by using SPSS version 16 and MS Excel 2013.

Result: Out of 200 COPD patients studied, female patients (58%) were higher than male patients and maximum patients (42.5%) were from the age group 70-79. The most common symptom was shortness of breath (77.5%) followed by cough (50%) and fever (33.5%) Hypertension (38.5%) was the most frequent co morbidity seen among COPD patients followed by corpulmonale (20%) and diabetes mellitus type II (19%). Doxophylline was the most prescribed methylxanthines during hospitalization (47.5%) and discharge (51%) as well. Among inhalers, Tiotropium bromide and combination of Salbutamol and Fluticasone (52.5%) was prescribed most to the hospitalised patients. Hydrocortisone (68.5%) was the most prescribed corticosteroids during hospitalization where as Prednisolone (49.5%) was the most prescribed corticosteroids during discharge. 85.5% of patients were prescribed Ipratropium bromide for nebulisation in hospitalised patients. Pantoprazole (55.5%) was the most prescribed proton pump inhibitors followed by Rabeprazole (34%). Maximum patients (103) preferred Rotacap than metered dose inhaler (MDI) and dry powder inhaler (DPI). Azithromycin (52.5%) was most frequently prescribed antibiotics during hospitalization followed by ceftriaxone (85%), whereas among discharge patients, Cefpodoxime (35%) was most frequently prescribed antibiotics followed by Azithromycin (32%). The drugs prescribed with generic name were 31.31% and from essential drug list (EDL) was 37.72 %.

Conclusion: The prescription pattern of COPD was studied and found that Doxophylline, Tiotropium bromide, Hydrocortisone and Azithromycin were most prescribed methylxanthnes, antimuscarinic agents, corticosteroids and antibiotics respectively. The findings from the study showed that prescribing drugs with generic name and from EDL was low so prioritization on prescribing drugs by generic name and EDL needs to be encouraged.
