Hospital-Based Quasi-Experimental Study on Hydroxychloroquine Pre-Exposure Prophylaxis for COVID-19 in Healthcare Providers with Its Potential Side-Effects.

ABSTRACT: Considering that it has been more than 24 months since SARS-CoV-2 emerged, it is crucial to identify measures that prevent and control pathogen transmission in workplace settings. Our aim was to report results of a hospital-based program that delivered hydroxychloroquine (HCQ) tablets as COVID-19 prophylaxis to the frontline healthcare workers (HCW)s who cared for COVID-19 patients and to evaluate the efficacy of HCQ. Setting and participants: Quasi-experimental, controlled, single-center study. The included participants were doctors, nurses, health workers, cleaning staff, and non-healthcare supportive staff. The main outcome was contracting COVID-19 anytime during the period of taking the prophylaxis, confirmed by RT-PCR. A total of 336 participants, without any clinical evidence of COVID-19 and without any known contact with family members, were included in the trial; 230 were assigned to HCQ and 106 declined to take any drug. Results: Among the participants, 43 (18.7%) in the HCQ group and 11 (10.4%) participants in the control group developed COVID-19. For the evaluation of side effects, we evaluated 12-lead ECGs of both groups at the baseline and after 4 weeks to monitor QTc interval. A total of 91% (198 of 217) participants in the prophylaxis group and 92% (11 of 12) in the control group had a QTc < 45o msec, which is within normal limits. Conclusions: Although the number of symptomatic infections in health personnel was lower in the control group, the difference was not statistically significant. However, in the absence of any effective pre-exposure prophylaxis medicine for COVID-19, practicing proper infection prevention and control (IPC) and vaccination is the only way forward.

Project description:BackgroundSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a rapidly emerging virus causing the ongoing coronavirus disease 2019 (COVID-19) pandemic with no known effective prophylaxis. We investigated whether hydroxychloroquine could prevent SARS-CoV-2 in healthcare workers at high risk of exposure.MethodsWe conducted a randomized, double-blind, placebo-controlled clinical trial of healthcare workers with ongoing exposure to persons with SARS-CoV-2, including those working in emergency departments, intensive care units, COVID-19 hospital wards, and first responders. Participants across the United States and in the Canadian province of Manitoba were randomized to hydroxychloroquine loading dose then 400 mg once or twice weekly for 12 weeks. The primary endpoint was confirmed or probable COVID-19-compatible illness. We measured hydroxychloroquine whole-blood concentrations.ResultsWe enrolled 1483 healthcare workers, of whom 79% reported performing aerosol-generating procedures. The incidence of COVID-19 (laboratory-confirmed or symptomatic compatible illness) was 0.27 events/person-year with once-weekly and 0.28 events/person-year with twice-weekly hydroxychloroquine compared with 0.38 events/person-year with placebo. For once-weekly hydroxychloroquine prophylaxis, the hazard ratio was .72 (95% CI, .44-1.16; P = .18) and for twice-weekly was .74 (95% CI, .46-1.19; P = .22) compared with placebo. Median hydroxychloroquine concentrations in whole blood were 98 ng/mL (IQR, 82-120) with once-weekly and 200 ng/mL (IQR, 159-258) with twice-weekly dosing. Hydroxychloroquine concentrations did not differ between participants who developed COVID-19-compatible illness (154 ng/mL) versus participants without COVID-19 (133 ng/mL; P = .08).ConclusionsPre-exposure prophylaxis with hydroxychloroquine once or twice weekly did not significantly reduce laboratory-confirmed COVID-19 or COVID-19-compatible illness among healthcare workers.Clinical trials registrationClinicaltrials.gov NCT04328467.

Project description:ObjectivesAn effective clinical decision support system (CDSS) may address the current provider training barrier to offering preexposure prophylaxis (PrEP) to youth at risk for human immunodeficiency virus (HIV) infection. This study evaluated change in provider knowledge and the likelihood to initiate PrEP after exposure to a PrEP CDSS. A secondary objective explored perceived provider utility of the CDSS and suggestions for improving CDSS effectiveness.MethodsThis was a prospective study using survey responses from a convenience sample of pediatric providers who launched the interruptive PrEP CDSS when ordering an HIV test. McNemar's test evaluated change in provider PrEP knowledge and likelihood to initiate PrEP. Qualitative responses on CDSS utility and suggested improvements were analyzed using framework analysis and were connected to quantitative analysis elements using the merge approach.ResultsOf the 73 invited providers, 43 had available outcome data and were included in the analysis. Prior to using the CDSS, 86% of participants had never been prescribed PrEP. Compared to before CDSS exposure, there were significant increases in the proportion of providers who were knowledgeable about PrEP (p = 0.0001), likely to prescribe PrEP (p < 0.0001) and likely to refer their patient for PrEP (p < 0.0001). Suggestions for improving the CDSS included alternative "triggers" for the CDSS earlier in visit workflows, having a noninterruptive CDSS, additional provider educational materials, access to patient-facing PrEP materials, and additional CDSS support for adolescent confidentiality and navigating financial implications of PrEP.ConclusionOur findings suggest that an interruptive PrEP CDSS attached to HIV test orders can be an effective tool to increase knowledge and likelihood to initiate PrEP among pediatric providers. Continual improvement of the PrEP CDSS based on provider feedback is required to optimize usability, effectiveness, and adoption. A highly usable PrEP CDSS may be a powerful tool to close the gap in youth PrEP access and uptake.
