Appendix D. Clinical data analysis methodology

Our clinical data analysis in this audit involved the five audited health services, which provided to us all community contacts and admissions for all clients aged 0–25 years across three years from 1 January 2015 to 31 December 2018.

The data that we received and analysed from CMI/ODS was:

  • 18 460 unique clients
  • 10 demographic fields that were used in the analysis were populated for 92 per cent of clients, though this included some 'unknown' responses
  • 28 191 program incidences (that is, admissions for inpatients or enrolment in a community program), which represented program-level information for 15 988 (87 per cent) clients
  • ICD 10 codes for diagnoses were available for 75 per cent of clients (93 per cent inpatients, 69 per cent community)
  • outcome measures—at least one was available for 61 per cent of clients, 46 per cent of clients had a HoNOSCA and 31 per cent had at least one SDQ score.

The data analysis sought to explore:

  • the current client group's demographics and clinical characteristics including levels of severity and complexity
  • the number of clients seen by CYMHS as a whole and each specific service within CYMHS, including emergency department presentations
  • the number, length and frequency of inpatient stays
  • the age and clinical characteristics of clients with longer inpatient stays.
