Mental health care cascade performance and associated factors: longitudinal analyses of routine Ministry of Health services in Mozambique.

Abstract

Abstract:

Introduction: Mental, neurological and substance use (MNS) disorders are leading causes of disability worldwide. Nevertheless, limited research exists regarding MNS health system performance across the care cascade and associated patient characteristics in low-income and middle-income countries (LMICs) such as Mozambique.

Methods: We used baseline data from an ongoing randomised controlled trial, collected across 16 outpatient clinics on variables of sex, age, marital status, tuberculosis and HIV status, alcohol and drug use, suicidal ideation, pregnancy and MNS diagnosis. Mixed-effects multivariable regression was used to examine factors associated with patient functional improvement or low functional impairment measured by a standardised disability questionnaire.

Results: From February to September 2022, there were 4323 patient visits, of which 65.9% (n=2851) were attended on time (±5 days), 41.4% (n=1793) had medication adherence and 30.5% (n=1321) achieved a functional impairment score <10 or 50% improvement from baseline. Patients 15-18 years old had 60% lower odds of demonstrating functional improvement or low functional impairment during a follow-up visit compared with those 26-35 years old (95% CI: 0.19, 0.85). Compared with single persons, those in a domestic union had 3.3 times higher odds of demonstrating functional improvement or low functional impairment (95% CI: 1.8, 6.1). Individuals expressing suicidal ideation had 85% lower odds of demonstrating functional improvement than those without suicidal ideation (95% CI: 0.02, 0.91). For patients new to treatment, each additional visit was associated with a mean reduction in functional impairment of 0.62 points (95% CI: -0.76, -0.47).

Conclusions: This analysis revealed gaps in patients reaching functional improvement or low functional impairment in outpatient MNS care in Mozambique. Gaps were more pronounced for patients who are ≤18 years of age, single or expressing suicidal ideation. Implementation strategies to optimise patient outcomes are needed as nascent mental health systems are scaled-up in Mozambique and other similar LMICs.
