Study name Improving the cardio‐metabolic health of people with psychosis
Methods Setting: community‐based mental health service in a large metropolitan city in Australia
Allocation: randomised controlled trial; block randomisation stratified by age and gender
Masking: participants and outcome assessors will be masked until after baseline assessment. Team members conducting data analysis will not be involved in data collection. Treatment allocations will be masked until after data analysis.
Participants Diagnosis: diagnosed with a DSM‐V psychotic disorder
n = 160
Age: 18 to 65
Interventions Physical health nurse consultant (PHNC): will co‐ordinate physical health care including supported referral to appropriate programmes/services. The PHNC will manage risk using the positive cardiometabolic health treatment framework and will work in collaboration with consumers on self‐identified needs, goals and health priorities.
Control: usual care
Comparison: PHNC + usual care vs usual care
Outcomes Primary outcomes:
  • Burden of disease risk factors

  • Consumer experience ('access', 'acceptability' and 'shared decision‐making' dimensions of the Patient Experiences in Primary Healthcare Survey)

  • Quality of life (Assessment of Quality of Life ‐ AQoL‐8D)

  • Cost‐effectiveness (assessing cost‐effectiveness prevention methodology)

Starting date Late 2018
