ABSTRACT
Background/Aims The impact of the pandemic on the incidence and management of inflammatory arthritis (IA) is not understood. Routinely-captured data in secure platforms, such as OpenSAFELY, offer unique opportunities to understand how IA was impacted upon by the pandemic. Our objective was to use OpenSAFELY to assess the effects of the pandemic on diagnostic incidence and care delivery for IA in England, and replicate key metrics from the National Early Inflammatory Arthritis Audit. Methods With the approval of NHS England, we used primary care and hospital data for 17 million adults registered with general practices using TPP health record software, to explore the following outcomes between 1 April 2019 and 31 March 2022: 1) incidence of IA diagnoses (rheumatoid arthritis, psoriatic arthritis, axial spondyloarthritis, undifferentiated IA) recorded in primary care;2) time to first rheumatology assessment;3) time to first prescription of a conventional synthetic DMARD (csDMARD) in primary care, and choice of first csDMARD. Results From 17,683,500 adults (representing 40% of the English population), there were 31,280 incident IA diagnoses recorded between April 2019 and March 2022. New IA diagnoses decreased by 39.7% in the early months of the pandemic. Overall, a 20.3% decrease in IA diagnoses was seen in the year commencing April 2020, relative to the preceding year (5.1 vs. 6.4 diagnoses per 10,000 adults, respectively). Further decreases coincided with rising COVID-19 numbers, before returning to pre-pandemic levels by the end of the study period. No rebound increase in IA incidence was observed as of April 2022. The median time from referral to first rheumatology assessment was shorter during the pandemic (18 days;IQR 8-35 days) than before (21 days;9-41 days). The proportion of patients prescribed csDMARDs in primary care was comparable to before the pandemic;however, fewer people were prescribed methotrexate or leflunomide, and more were prescribed sulfasalazine or hydroxychloroquine. Conclusion IA diagnoses decreased markedly during the early phase of the pandemic;however, the impact on rheumatology assessment times and DMARD prescribing was less marked than might have been anticipated. This study demonstrates the feasibility of using routinelycaptured, near real-time data in the secure OpenSAFELY platform to benchmark care quality on a national scale, without the need for manual data collection.
ABSTRACT
Surgical decision-making after SARS-CoV-2 infection is influenced by the presence of comorbidity, infection severity and whether the surgical problem is time-sensitive. Contemporary surgical policy to delay surgery is informed by highly heterogeneous country-specific guidance. We evaluated surgical provision in England during the COVID-19 pandemic to assess real-world practice and whether deferral remains necessary. Using the OpenSAFELY platform, we adapted the COVIDSurg protocol for a service evaluation of surgical procedures that took place within the English NHS from 17 March 2018 to 17 March 2022. We assessed whether hospitals adhered to guidance not to operate on patients within 7 weeks of an indication of SARS-CoV-2 infection. Additional outcomes were postoperative all-cause mortality (30 days, 6 months) and complications (pulmonary, cardiac, cerebrovascular). The exposure was the interval between the most recent indication of SARS-CoV-2 infection and subsequent surgery. In any 6-month window, < 3% of surgical procedures were conducted within 7 weeks of an indication of SARS-CoV-2 infection. Mortality for surgery conducted within 2 weeks of a positive test in the era since widespread SARS-CoV-2 vaccine availability was 1.1%, declining to 0.3% by 4 weeks. Compared with the COVIDSurg study cohort, outcomes for patients in the English NHS cohort were better during the COVIDSurg data collection period and the pandemic era before vaccines became available. Clinicians within the English NHS followed national guidance by operating on very few patients within 7 weeks of a positive indication of SARS-CoV-2 infection. In England, surgical patients' overall risk following an indication of SARS-CoV-2 infection is lower than previously thought.
