We describe the patterns of COPD-related visits in Sweden, both regular follow-up and post-exacerbation visits.Methods: Patients (> 40 years) with a first-time COPD diagnosis between 2006 and 2017 were identified in primary care medical records and linked to hospital contacts and administered drug data. The index date was defined as the first collection of inhaled COPD maintenance treatment after the diagnosis. Regular COPD visits within 15-months after the index, and post-exacerbation visits for COPD within six weeks and 15-months after an exacerbation were estimated using the cumulative incidence function adjusted for competing risk. Visits without a ICD code for COPD were not included in the analyses.Results: A total of 19,857 patients (mean age 69 years, 57% females) were included. The overall probability of having a regular follow-up
