The Cost of Illness of Hypertension and Associated Factors at the University of Gondar Comprehensive Specialized Hospital Northwest Ethiopia, 2018

Abstract

Purpose: Non-communicable diseases impose a significant social, economic and health burden. Hypertension, the leading contributor to the global burden of disease and a growing public health problem worldwide, is one of the most serious non-communicable diseases. In Ethiopia, empirical evidence on the economic burden of hypertension is limited. Therefore, this study aimed to measure the cost of hypertension and associated factors at the University of Gondar comprehensive specialized hospital, northwest Ethiopia. Patients and Methods: An institution-based cross-sectional study was conducted on 442 adult hypertensive patients using a semi-structured questionnaire to estimate the direct and indirect costs of hypertension. The human capital approach was used to calculate indirect costs. A generalized linear model was fitted to identify factors associated with the cost of hypertension at a 95% confidence level and <0.05 p-value. Results: A total of 442, 56.3% female and 64.3% stage one hypertension patients were included. The total cost of hypertension was ETB 2510.32 ($91.72) ± 2152.80 (78.65) per patient per year; The direct medical and non-medical cost constituted 60.81% and 12.17% of the total cost of hypertension, respectively. Hospitalized (exp(b)=1.87, p<0.001), using multidrug (exp(b)=1.32, p<0.000), high socioeconomic status (exp(b)=1.41,p<0.000), college and above education(exp(b)= 1.35, p<0.016), government employment (exp(b)= 1.30, p<0.012), retirement (exp(b)= 0.71, p< 0.001) and co-morbidity (exp(b)= 1.20, p<0.004) were factors significantly associated with the cost of hypertension. Conclusion: The total cost of illness of hypertension is high, and direct medical cost has the highest component of the total cost of illness. Hospitalization, using multidrug, co-morbidity, attending college and above education, highest socioeconomic status and government employment were factors significantly associated with the high cost of hypertension. Therefore, prevention and early detection of complications and co-morbidity are essential to reduce hospitalization and the number of drugs to reduce the direct medical and indirect costs
