Background: Hydroxychloroquine (HC) § azithromycin (AZ) is widely used for Covid-19. The Qatar Prospective RCT of Expediting Coronavirus Tapering (Q-PROTECT) aimed to assess virologic cure rates of HC §AZ in cases of low-acuity Covid-19. Methods: Q-PROTECT employed a prospective, placebo-controlled design with blinded randomization to three parallel arms: placebo, oral HC (600 mg daily for one week), or oral HC plus oral AZ (500 mg day one, 250 mg daily on days two through five). At enrollment, non-hospitalized participants had mild or no symptoms and were within a day of Covid-19 positivity by polymerase chain reaction (PCR). After six days, intentto-treat (ITT) analysis of the primary endpoint of virologic cure was assessed using binomial exact 95% confidence intervals (CIs) and x 2 testing. (ClinicalTrials.gov NCT04349592, trial status closed to new participants.) Findings: The study enrolled 456 participants (152 in each of three groups: HC+AZ, HC, placebo) between 13 April and 1 August 2020. HC+AZ, HC, and placebo groups had 6 (3¢9%), 7 (4¢6%), and 9 (5¢9%) participants go off study medications before completing the medication course (p = 0¢716). Day six PCR results were available for all 152 HC+AZ participants, 149/152 (98¢0%) HC participants, and 147/152 (96¢7%) placebo participants. Day six ITT analysis found no difference (p = 0¢821) in groups' proportions achieving virologic cure: HC +AZ 16/152 (10¢5%), HC 19/149 (12¢8%), placebo 18/147 (12¢2%). Day 14 assessment also showed no association (p = 0¢072) between study group and viral cure: HC+AZ 30/149 (20¢1%,), HC 42/146 (28¢8%), placebo 45/ 143 (31¢5%). There were no serious adverse events. Interpretation: HC §AZ does not facilitate virologic cure in patients with mild or asymptomatic Covid-19. Funding: The study was supported by internal institutional funds of the Hamad Medical Corporation (government health service of the State of Qatar).

Background: There are scant data regarding the change in volume and acuity of patients presenting to emergency departments (EDs) after Coronavirus Disease 2019 (COVID-19), compared with the pre-COVID-19 era. Objective: To determine ED volumes and triage acuity prior to and after COVID-19. Methods: We determined the volume of patients presenting to four large EDs affiliated with general, cardiac, cancer, and obstetrics hospitals, and the acuity of presenting illness (using the Canadian Triage Acuity Scale [CTAS]) for March and April 2020 and compared them with the same months in 2019 and January 2020. Together, these facilities see over 80% of the ED visits in Qatar. The first COVID-19 patient in Qatar was diagnosed on February 29, 2020. Results: A total of 192,157 ED visits were recorded during the study period. There was a 20-43% overall drop in number of ED visits, with significant variability across hospitals. The Heart Hospital experienced the sharpest decline (33-89%), and the National Center for Cancer Care and Research experienced the least decline in volumes. The decline was observed across all CTAS levels, with the largest decline observed in individuals presenting with CTAS 1 and 2 (26-69% decline month by month). No increase in overall number of deaths or crude mortality rate was observed in the COVID-19 era, according to national statistics. Conclusions: Sharp declines in ED visits and the triage acuity seen in both general and specialty hospitals raise the concern that severely ill patients may not be seeking timely care, and a surge may be expected once current restrictions on movement are lifted.

Objectives The impact of COVID-19 upon acute care admission rates and patterns are unknown. We sought to determine the change in rates and types of admissions to tertiary and specialty care hospitals in the COVID-19 era compared with pre-COVID-19 era. Methods Acute care admissions to the largest tertiary care referral hospital, designated national referral centers for cardiac, cancer and maternity hospital in the State of Qatar during March 2020 (COVID-19 era) and January 2020 and March 2019 (pre-COVID-19 era) were compared. We calculated total admissions, admissions for eight specific acute care conditions, in-hospital mortality rate, and length of stay at each hospital. Results A total of 18,889 hospital admissions were recorded. A sharp decline ranging from 9% to 75% was observed in overall admissions. A decline in both elective and non-elective surgeries was observed. A decline of 9%–58% was observed in admissions for acute appendicitis, acute coronary syndrome, stroke, bone fractures, cancer, and live births, whereas an increase in admissions due to respiratory tract infections was observed. Overall length of stay was shorter in the COVID-19 period possibly suggesting lesser overall disease severity, with no significant change in in-hospital mortality. Unadjusted mortality rate for Qatar showed marginal increase in the COVID-19 period. Conclusions We observed a sharp decline in acute care hospital admissions, with a significant decline in admissions due to seven out of eight acute care conditions. This decline was associated with a shorter length of stay but not associated with a change in in-hospital mortality rate.
