This guide is concerned with productivity measurement and improvement in mental health centers, and focuses on the relationship between service outputs and available clinical staff, i.e., staff productivity. Staff productivity measures are described as useful in identifying existing levels of productivity, making comparisons to determine the adequacy of these levels, and monitoring changes over time. Other assessments which determine the nature of the workload are presented. The strategies designed to improve the productivity of the clinical staff focus on methods for increasing the amount of services provided, including: (1) making better use of clinical staff time; (2) increasing the demand for services and (3) improving ongoing management practices.
