Background General practice registrars see fewer older patients with chronic disease than established general practitioners (GPs). Furthermore, registrars have fewer opportunities to be involved in continuity of care for older patients. Objective The aim of this study was to explore the experiences of general practice supervisors and registrars when providing in-practice care for older patients with chronic disease. Methods Three focus groups and 21 interviews (18 supervisors, 17 registrars) were conducted, recorded and transcribed. The main themes were derived using thematic analysis. Results Three main themes were reported: context influences registrars' exposure to older patients; opportunities for continuity of care need ongoing negotiation and communication; registrars are competent-trust and confidence follows. Discussion Developing tailored models of shared patient care that suit different practices and supervisors will require ongoing negotiation and communication. This study confirms the need to enhance exposure for general practice registrars in ways that build on the competence of registrars and the trust in registrars by older patients and supervisors. AN AGEING POPULATION with a higher prevalence of multimorbid chronic conditions is placing pressure on general practice to provide optimal care to older Australians. 1 Yet general practice registrars see fewer older patients with chronic disease than established general practitioners (GPs). 2,3 Furthermore, registrars have fewer opportunities to be involved in the continuity of care needed for older patients with chronic disease. 4 The Registrars' Clinical Encounters in Training (ReCEnT) project 5 demonstrated that general practice registrars have relatively limited exposure to older people, particularly older peple with chronic conditions. 2 Moreover, continuity of care in Australian registrars' training experience is modest, 4 yet older patients are willing to see a general practice registrar, 6 especially when given relevant information. 7 The challenge is how to increase exposure to aged care and chronic conditions by general practice registrars and, at the same time, maintain continuity of care by the patient's regular GP. Models for registrars' management of complex problems are needed to address gaps in aged care management and teaching in general practice. 8 The data in this article are drawn from a qualitative study that explored approaches to in-practice aged care teaching and exposure by registrars to older patients in general practice. This article presents findings from interviews and focus groups with supervisors and registrars regarding their experiences of registrars' exposure to, engagement with, and continuity of care for older patients with chronic disease, with the goal of eliciting ideas for shared patient care models. Methods We used purposive sampling of general practice supervisors and registrars in Tasmania to explore supervisors' and registrars' views across the state and at regional levels. We chose an interpretivist perspecti...
