Estimating mental health service coverage is crucial for scaling up care. Few studies exist, but combining routine data with national surveys offers a low-cost solution for tracking progress.
Area of Science:
- Mental Health Services Research
- Public Health Policy
- Health Systems Strengthening
Background:
- Significant treatment gap exists for mental disorders globally.
- Initiatives aim to scale up mental health services to address this gap.
- Accurate programme coverage estimates are essential for monitoring progress.
Purpose of the Study:
- To systematically review methods for estimating mental health programme coverage.
- To assess available data on contact coverage and effective coverage.
- To identify feasible methods for coverage estimation in programme evaluations.
Main Methods:
- Systematic review of mental health programme evaluations up to March 2013.
- Searched electronic databases, grey literature, and contacted experts.
- Reviewed methods for estimating service utilization (numerator) and target population (denominator).
Main Results:
- Only seven studies met inclusion criteria out of 15,735 records.
- All studies reported contact coverage; effective coverage was estimated in only one.
- Service utilization was mostly estimated from routine clinical data; denominator estimation methods varied.
Conclusions:
- There is a scarcity of available mental health service coverage estimates.
- Low-cost estimation is possible by integrating routine programme data with national population prevalence.
- This approach can facilitate tracking progress in scaling up mental health services.
