'Low-value' clinical care in general practice: associations of low value care in GP trainees' practice, including formative and summative examination performance - protocol for cross-sectional and retrospective cohort study analyses using the QUestionable In Training Clinical Activities (QUIT-CA) index.

'Low value' clinical care and overuse of medical services are 'questionable' clinical activities that entail provision of medical services that are more likely to cause harm than good or whose benefit is disproportionately low compared with its cost. This study will seek to establish clinical practice associations of a non-observed work-based assessment of general practitioner (GP) trainees' (registrars') questionable practice (the QUestionable In Training Clinical Activities (QUIT-CA) index). We will also explore association of the QUIT-CA index with a formative observed work-based assessment, and will establish if registrars' QUIT-CA indexes are associated with summative examination performance. We will conduct three analyses, all using data from the Registrar Clinical Encounters in Training (ReCEnT) study. ReCEnT is an ongoing (from 2010) cohort study in which Australian GP registrars record details of their in-consultation clinical and educational practice. The QUIT-CA index is compiled from ReCEnT consultation data. A cross-sectional analysis, using negative binomial regression, will establish clinical practice associations of the QUIT-CA index. A cross-sectional analysis using linear regression will be used to establish associations of QUIT-CA index with formative observed in-practice assessment (the General Practice Registrar-Competency Assessment Grid). A retrospective cohort study analysis using linear regression will be used to establish associations of the QUIT-CA index with summative examination performance (Royal Australian College of General Practice fellowship examinations results). The study has ethical approval from the University of Newcastle HREC(H-2009-0323). Findings will be disseminated in peer-reviewed journal articles and conference presentations.
