The out-of-pocket cost of breast cancer care in Nigeria: A prospective analysis

Abstract

Background: Most patients pay out-of-pocket for cancer care in Nigeria, which can result in a catastrophic health care expenditure (CHE). There is a paucity of economic data on the cost of care and the impact this may have on the household. This study provides a prospective analysis of direct and indirect out-of-pocket costs for breast cancer care at a single tertiary care institution in South West Nigeria.

Methods: Consecutive patients undergoing curative intent treatment for a new diagnosis of breast cancer between August 2019 and September 2022 were approached for enrollment. A novel questionnaire was delivered to patients during hospital admission and again during six-month follow-up. Patients self-reported annual household income, capacity-to-pay, and all direct and indirect expenditures associated with access care. A CHE was defined using three commonly used definitions, including total healthcare expenditure that exceeds 40 % of a household's capacity-to-pay, or exceeds the proportion of annual income set at thresholds of 10 % and 25 %.

Results: Data were collected from 71 eligible patients with a mean age of 49.5 years (SD 11.26). Sixty-six percent (47/71, 66.2 %) of patients had ≥ Stage III disease at presentation, and 95.8 % received systemic chemotherapy. Only 23.9 % received adjuvant radiotherapy. The mean annual capacity-to-pay for the cohort was $2866.93 (SD $2749.74). The mean cost of care was $5192.77 (SD $4567.71). Out of the 71 patients enrolled in the study, between 56 (78.9 %) and 71 (100 %) experienced a CHE, depending on the included costs (direct +/- indirect) and threshold used. Sixty-six percent of patients had no form of health insurance.

Conclusions: Over 70 % of breast cancer patients at a tertiary care facility in Nigeria experience a CHE because of out-of-pocket costs associated with accessing care.

Policy summary: A more effective and accessible health insurance mechanism is required in Nigeria to protect women with breast cancer from the cost of cancer care.
