ABSTRACT
Care of osteoporosis patients during COVID-19 pandemic is challenging. Due to lockdowns and restrictions, the management of osteoporosis has changed. Diagnosis of osteoporosis decreased and the influence of COVID-19 on drug prescriptions and dispensing is currently unclear. Therefore, the aim of the study was to assess the dispensing of anti-osteoporotic drugs during the Covid19 pandemic. Methods This study was a nationwide retrospective register-based observational study which included all patients in Austria aged >= 50 who received at least one prescription for anti-osteoporotic drug between January 2016 and November 2020. Pseudonymized individual-level patients' data were obtained from social insurance authorities and the Federal Ministry of Labour, Social Affairs, Health and Consumer Protection in Austria. Anti-osteoporotic agents were divided into (i) oral bisphosphonates, (ii) intravenous bisphosphonates, (iii) selective estrogen receptor modulators (SERMs), (iv) teriparatide (TPTD) and (v) Denosumab (DMAB). We used interrupted time series analysis with autoregressive integrated moving average models (ARIMA) for the prediction of drug dispensing. Results There were 2,884,627 dispensing of anti-osteoporotic drugs by 318,573 patients between 2016-2020. The mean monthly prescriptions for oral bisphosphonates (-14.5 %) and SERMs (-12.9 %) decreased during COVID-19 pandemic, compared to the non-COVID-19 period. The dispensing for intravenous bisphosphonates (1.7 %) and teriparatide (9.5 %) increased during COVID- 19. The prescriptions for DMAB decreased during the first lock-down in March and April 2020 (24 %), however increased by 29.1 % for the total observation time. The ARIMA model for alendronate showed, that the estimated step change was minus 1443 dispensing (95 % CI - 2870 to - 17), while the estimated change in slope was minus 29 dispensing per month (95 % CI - 327 to 270). Thus, there were 1472 (1443 + 29) fewer dispensing in March 2020 than predicted had the lockdown not occurred. Discussion The total number of prescriptions dispensed to patients treated with anti-osteoporotic medications declined rapidly during the first COVID-19 lockdown. The largest drops in absolute terms were observed for ibandronate, followed by alendronate, denosumab, zolendronic acid and risendronate. The observed decrease of DMAB during the first lockdown, was compensated in the following months. Current evidence suggests no need for discontinuation of anti-osteoporotic drugs during COVID-19 pandemic, nor because of vaccination. Taking into account the massive treatment gap for osteoporosis, and the related fracture risk, clinicians should continue treatment, even in times of pandemics.
