title: Using Avoidable Admissions to Measure Quality of Care for Cardiometabolic and Other Physical Comorbidities of Psychiatric Disorders: A Population-Based, Record-Linkage Analysis.
abstract: OBJECTIVE
  Quality of care for comorbid physical disorders in psychiatric patients can be assessed by the number of avoidable admissions for ambulatory care sensitive (ACS) conditions. These are admissions for physical conditions that, with appropriate primary care, should not require inpatient treatment. Avoidable admissions for ACS conditions feature prominently in Australia's National Health Performance Framework and have been used to assess health care provision for marginalized groups, such as Indigenous patients or those of lower socioeconomic status. They have not been applied to people with mental illness.
  
  
  METHODS
  A population-based, record-linkage analysis was used to measure ACS admissions for physical disorder in psychiatric patients of state-based facilities in Queensland, Australia, during 5 years.
  
  
  RESULTS
  There were 77 435 males (48.0%) and 83 783 females (52%) (total n = 161 218). Among these, 13 219 psychiatric patients (8.2%) had at least 1 ACS admission, the most common being for diabetes (n = 6086) and angina (n = 2620). Age-standardized rates were double those of the general population. Within the psychiatric group, and after adjusting for confounders, those who had ever been psychiatric inpatients experienced the highest rates of ACS admissions, especially for diabetes.
  
  
  CONCLUSIONS
  In common with other marginalized groups, psychiatric patients have increased ACS admissions. Therefore, this measure could be used as an indicator of difficulties in access to appropriate primary care in Canada, given the availability of similar administrative data.
