A model for estimating mental health service needs in South Africa
Abstract
Objective. To develop a model for estimating the services and human resources needed. to care for people with severe psychiatric conditions in a hypothetical population of 100 000 people in South Africa.
Method. Annual mental health service needs were estimated. in terms of numbers of daily patient visits (DPV) in ambulatory care, the number of beds required, and staffing_ Developed within a spreadsheet format, the model allows for the adjustment of key service variables according.to estimated or existing service data.
Results. At 100% coverage, 87 DPV, 28 acute beds, and 10 medium-long stay beds are necessary for a population of 100 000 people. This would require 352 full-time equivalent mental health staff: 21.3 for inpatient care, 12.0 for ambulatory care, and 1.9 for management.
Conclusion. Because the model can produce a range of service recommendations, the assumptions that inform it should be clearly stated. and justified.. This method makes the assumptions on which services are planned. explicit and allows for a rational approach to decision making.
