Impact of the first wave of the COVID-19 pandemic on healthcare use in osteoarthritis : A population register-based study in Sweden

• Objective: To investigate whether the first wave of the COVID-19 pandemic impacted healthcare consultations (HCC) and hospitalization among people with and without osteoarthritis (OA).Methods: Using register data, we included individuals aged ≥35 years residing in Skåne region, Sweden, during 2009-2019 with (n ​= ​123,523) and without (n ​= ​552,412) a diagnosis of OA during January 1, 2009-December 31, 2019. We collected bi-weekly individual data on HCC/hospitalization between January and May for years 2017-2020. Treating the year 2020 as intervention and 2017-2019 as control as well as dividing data to pre- (January-February) and post-pandemic (March-May), we applied event study design to measure the dynamic effects of the COVID-19 pandemic on HCC/hospitalization. We used fixed-effect Poisson regressions for estimation and subgroup analyses by sex, age, and comorbidity were conducted among OA patients.Results: The impact of the pandemic on healthcare use was evident from mid-March 2020 (34-45%/12-25% reductions in in-person HCC/hospitalization) among people with OA relative to 2017-2019. Smaller reductions were seen in those without OA with 25-34%/8-16% reductions in in-person HCC/hospitalization. On contrary, there were increases in remote HCC following the pandemic (5-25% and 11-31% in people with and without OA, respectively). Among persons with OA, there were variations in the pandemic's effects by sex, age and comorbidity.Conclusion: Despite no lockdown in Sweden there were substantial reductions in in-person healthcare use during the first wave of COVID-19 pandemic with greater reductions among people with than without OA.
