Systematic review and meta analysis of 20 studies on HCQ use in rheumatic disease patients, showing significantly lower mortality and hospitalization with HCQ prophylaxis.
Currently there are 90 HCQ pre-exposure prophylaxis studies and meta analysis shows:
OutcomeImprovement
Mortality30% lower [11‑45%]
Cases31% fewer [22‑38%]
risk of death, 24.0% lower, OR 0.76, p = 0.010, RR approximated with OR.
risk of hospitalization, 20.0% lower, OR 0.80, p = 0.04, RR approximated with OR.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

Therefore, we sought to assess the mortality in rheumatic patients with chronic HCQ/CQ use who developed a COVID-19 infection through a comparison between individuals chronically using HCQ/CQ with those not taking these drugs. We performed a systematic review and meta-analysis of studies on PubMed, Embase, and Cochrane Central. We included full-length reports, prospective observational cohorts, and clinical trials of adult patients (aged ≥ 18 years) who were diagnosed with a COVID-19 infection. Case studies, case series, letters, comments, and editorials were excluded. The main outcome was all-cause mortality. This study is registered with PROSPERO (CRD42022341678). We identified 541 studies, of which 20 studies were included, comprising 236,997 patients. All-cause mortality was significantly lower in patients with prior chronic use of HCQ/CQ compared to those with no previous usage (OR 0.76; 95% CI 0.62–0.94; p = 0.01). There was a considerably lower incidence of hospitalization among patients with chronic HCQ/CQ use compared to their counterparts without HCQ/CQ usage (OR 0.80; 95% CI 0.65–0.99; p = 0.04). All-cause mortality and hospitalization were significantly lower in rheumatic patients with chronic HCQ/CQ use who developed a COVID-19 infection.
