*Patient and GP characteristics were identified 12 months before the identified discontinuity, unless otherwise stated.
†Incidents of discontinuity of care. Some patient could experience several episodes of discontinuity during our observation time, and hence be counted more than once.
‡Educational level measured in 2016.
§Municipality in which the patient’s GP was registered. Municipality size per 2. quarter of 2019.
ACSC, ambulatory care sensitive conditions; GP, general practitioner.
