Estimated ORs with 95% CIs for one or more monthly GP consultations, out-of-hours service consultations, acute hospital admissions and hospital admissions for ACSC during (3-month period) and after (1–6 months after and 7–12 months after) a sudden discontinuity of GP care, compared with a 12-month stable control period before the discontinuity. GEE analyses based on repeated monthly measurements within patient within GP, with separate analyses for each patient age group and adjustment for month/time, calendar month, calendar year, patient age and sex (2007–2017)
