The prevalence and care of mental disorders in Counties Manukau District Health Board from linked health data

Health datasets were linked to identify those people in CMDHB and other Northern DHBs that received care for a mental illness in 2007. This study has defined a new methodology for estimating the descriptive epidemiology of mental health disorders using linked anonymised health data. Although not formally validated it provides a view of mental health care not previously available for CMDHB, and reveals service use by different groups, relationships between services, and linkages between mental health and physical health.
