title: Case mix in paediatric rheumatology: implications for training in Australia.
abstract: BACKGROUND
  Despite a move towards the provision of specialist training in Australia in settings that extend beyond the public hospital system, formal comparisons of case mix between public and private specialty clinics have rarely been performed. It is therefore unclear for many specialties how well training in one setting prepares trainees for practice in the other.
  
  
  OBJECTIVE
  This study aims to compare the case mix of paediatric rheumatology patients seen in public and private settings and the referral sources of patients in each.
  
  
  METHODS
  An audit of all new patients seen in the public and private paediatric rheumatology clinics on campus at Royal Children's Hospital between June 2009 and January 2011. Data related to demographics, primary diagnosis, referral source and location seen were abstracted and compared.
  
  
  RESULTS
  Eight hundred and seventy-six new patients were seen during the period of interest. Of these, 429 patients (48.9%) were seen in private clinics. The commonest diagnostic categories for both type of clinics were non-inflammatory musculoskeletal pain/orthopaedic conditions (public 39.4%, private 33.6%) followed by juvenile idiopathic arthritis (public 16.6%, %, private 18.6%), other skin/soft tissue disorders (public 8.7%, private 9.6%) and pain syndromes (public 4.9%, private 11.4%). Patients with haematological and vasculitic disorders were predominantly seen in public clinics. The commonest source of referrals to both clinics was general practitioners (public 40.6%, private 53.1%).
  
  
  CONCLUSIONS
  The case mix in private paediatric rheumatology clinics closely mirrors that of public clinics at our centre. Training in either setting would provide sufficient case-mix exposure to prepare trainees for practice in the other.
