To test this we compared mental health clients MHCs with non-MHCs on potentially preventable hospitalisations PPHs as an indicator of the quality of primary care received. Methods Population-based retrospective cohort study of 139 208 MHCs and 294 180 matched non-MHCs in Western Australia from 1990 to 2006 using linked data from electoral roll registrations mental health registry MHR records hospital inpatient discharges and deaths. We used the electoral roll data as the sampling frame for both cohorts to enhance internal validity of the study and the MHR to separate MHCs from non-MHCs. Rates of PPHs overall and by PPH category and medical condition were compared between MHCs category of mental disorders and non-MHCs. Multivariate negative binomial regression analyses adjusted for socio-demographic factors case mix and the year at the start of follow up due to dynamic nature of study cohorts. Results PPHs accounted for more than 10 of all hospital admissions in MHCs with diabetes and its complications adverse drug events ADEs chronic obstructive pulmonary disease COPD convulsions and epilepsy and congestive heart failure being the most common causes. Compared with non-MHCs MHCs with any mental disorders were more likely to experience a PPH than non-MHCs overall adjusted rate ratio ARR 95 confidence interval CI . ARRs of PPHs were highest for convulsions and epilepsy nutritional deficiencies COPD and ADEs. The ARR of a PPH was highest in MHCs with alcohol drug disorders affective psychoses other psychoses and schizophrenia. .
