Economic Cost of Schizophrenia in a Nigerian Teaching Hospital.

Objective: This study evaluated the economic cost of schizophrenia in Nigerian patients and identified factors that influence cost.

Methods: A total of 100 participants with schizophrenia were assessed using the modified economic cost questionnaire, the mini-international neuropsychiatric interview, the positive and negative syndrome scale, the Liverpool University Neuroleptic side-effect rating scale, and the global assessment of functioning scale. Associations between sociodemographic characteristics, illness-related variables and direct, indirect, and total costs of schizophrenia were assessed.

Results: The average annual total, direct, and indirect costs of the treatment were $818.48, $349.59, and $468.89, respectively, per patient. The direct cost constituted 42.7%, while the indirect cost was 57.3% of the total costs of treatment. Hospitalization was the leading contributor to the direct cost, while productivity loss was a major component of the indirect cost.

Conclusion: Schizophrenia is an expensive disease in Nigeria, measures to reduce hospitalization could significantly reduce the cost of illness to the patient and their relatives.
