Evaluation of the prevalence of new-onset musculoskeletal symptoms in patients hospitalized for severe SARS-CoV-2 infection during the first two COVID waves in France: A descriptive analysis of the clinical data warehouse of 39 hospitals in France.

ABSTRACT

OBJECTIVE: To determine the prevalence of musculoskeletal (MSK) symptoms appearing after a SARS-CoV-2 infection. METHODS: This was an observational cohort based on data available at the Assistance publique-Hôpitaux de Paris (AP-HP) Clinical Data Warehouse (which includes data of more than 11 million patients treated in the 39 hospitals from AP-HP). The data collected included both ICD-10 codes in discharge summaries, and recurring wording expressions search on medical electronic documents. To be included in the analysis, patients had to have a positive RT-PCR for SARS-CoV-2 and be admitted in any department of AP-HP. Patients with previous history of any MSK condition were excluded. MSK conditions were considered if occurring up to 90days after the positive RT-PCR. Demographics and disease characteristics including treatment were compared in both groups (MSK yes/no) by t-test or Chi2 test, accordingly. RESULTS: In total, 17,771 patients had a positive SARS-CoV-2 RT-PCR at APHP and were admitted in any department of AP-HP. Among them, 15,601 had no previous history of MSK condition and among them, 1370 (8.8%) presented with MSK symptoms after the viral infection. The most prevalent MSK symptoms were back pain (32.9%), followed by arthralgia (29.9%), radicular pain (20.2%) and arthritis (22.8%). Patients with MSK symptoms (MSK+) were older (67 y vs. 64 y, P<0.01), more frequently obese (29% vs. 25%, P=0.03), hypertensive (34% vs. 30%, P<0.01) and with diabetes (21% vs. 18%, P<0.01). Treatment for SARS-CoV-2 was slightly different in both groups, with higher corticosteroids (40.7% vs. 29.0%, P<0.01), antivirals (21.5% vs. 15.3%, P<0.01) and immunosuppressors (8.5% vs. 4.5%, P<0.01) prescription rates in the MSK+ group. CONCLUSION: MSK symptoms occurred in almost 9% of patients admitted to the hospital after a SARS-CoV-2 infection, particularly in older and more comorbid patients. Further analysis evaluating whether these symptoms remain over time are needed.
