This study describes patient characteristics and presentations to community-based primary care medical services in the after-hours period. A cross-sectional survey completed by practitioners was voluntarily conducted over one weeknight and weekend in 2019 at 31 of 51 extended hours general practices (GP), three of three medical deputising services and three of three nurse-led walk-in clinics (WICs). Of 3371 community-based after-hours presentations, 934 consultation records were obtained (overall response: 28%). Emergency departments reported 524 triage code 4 and 5 patients within the study period. Problems managed in community-based after-hours services were most often rated as non-urgent (n = 482; 51.6%) and new (n = 606; 64.9%). The most common community-based after-hours presentations were diagnostic or disease related (e.g. infections or injury; n = 667; 59.5%). The most common body systems impacted were respiratory (n = 329; 29.6%), skin (n = 164; 16.4%) and general/unspecified (e.g. fever; n = 164; 16.4%). Community-based after-hours services reported different types of presentations, with medical deputising services reporting more urgent presentations, GPs reporting more procedural presentations and walk-in clinics reporting more skin-related issues (e.g. wound care). Community-based after-hours medical services contribute significantly to after-hours medical care in the ACT. Patients are self-selecting community-based after-hours medical services appropriately based on problems managed by practitioners.
