Burden of out-of-pocket payments among patients with cardiovascular disease in public and private hospitals in Ibadan, South West, Nigeria: a cross-sectional study

OBJECTIVE: Given that the mechanism for financial protection is underdeveloped in Nigeria, out-of-pocket (OOP) payment for treating cardiovascular disease could impose substantial financial burden on individuals and their families. This study estimated the burden of OOP expenditures incurred by a cohort of patients with cardiovascular disease (CVD) in Ibadan, Nigeria. DESIGN AND SETTINGS: This study used a descriptive cross-sectional study design. A standardised survey questionnaire originally developed by Initiative for Cardiovascular Health Research in Developing Countries was used to electronically collect data from all the 744 patients with CVD who accessed healthcare between 4 November 2019 and 31 January 2020 in the cardiology departments of private and public hospitals in Ibadan, Nigeria. Baseline characteristics of respondents were presented using percentages and proportions. The OOP payments were reported as means±SDs. Costs/OOP payments were in Nigerian Naira (NGN). The average US dollar to NGN at the time of data collection was ₦362.12 per $1. All quantitative data were analysed using STATA V.15. OUTCOME MEASURES: The burden of outpatient, inpatient and rehabilitative care OOP payments. RESULTS: Majority of the patients with CVD were within the age range of 45–74 years and 68.55% of them were women. The diagnostic conditions reported among patients with CVD were hypertensive heart failure (84.01%), dilated cardiomyopathy (4.44%), ischaemic heart disease (3.9%) and anaemic heart failure (2.15%). Across all the hospital facilities, the annual direct and indirect outpatient costs were ₦421 595.7±₦855 962.0 ($1164.2±$2363.8) and ₦19 146.5±₦53 610.1 ($52.87±$148.05). Similarly, the average direct and indirect OOP payments per hospitalisation across all facilities were ₦182 302.4±₦249 090.4 ($503.43±$687.87) and ₦14 700.8±₦ 69 297.1 ($40.60±$191.37), respectively. The average rehabilitative cost after discharge from index hospitalisation was ₦30 012.0 ($82.88). CONCLUSION: The burden of OOP payment among patients with CVD is enormous. There is a need to increase efforts to achieve universal health coverage in Nigeria.
