Understanding patient experience is necessary to advance the patient-centred approach to health service delivery. Australia’s primary healthcare model, the ‘Health Care Home’, is based on the ‘Patient-Centered Medical Home’ (PCMH) model developed in the United States. Both these models aim to improve patient experience; however, the majority of existing PCMH model evaluations have focussed on funding, management and quality assurance measures. This review investigated the scope of evidence reported by adult patients using a PCMH. Using a systematic framework, the review identified 39 studies, sourced from 33 individual datasets, which used both quantitative and qualitative approaches. Patient experience was reported for model attributes, including the patient–physician and patient–practice relationships; care-coordination; access to care; and, patient engagement, goal setting and shared decision-making. Results were mixed, with the patient experience improving under the PCMH model for some attributes, and some studies indicating no difference in patient experience following PCMH implementation. The scope and quality of existing evidence does not demonstrate improvement in adult patient experience when using the PCMH. Better measures to evaluate patient experience in the Australian Health Care Home model are required.
