Comparison of interventions/treatments used for patients in both hospitals
The majority of the patients (93%) were admitted to the ICU at some point and most of the patients (89%) required ventilation during their treatment course. There was no statistically significant difference between hospitals in the ICU admission (P -value= 0.644) or ventilation rates (P -value= 0.262) among the included patients. Regarding drugs administered, about two thirds (64%) of the patients were treated with hydroxychloroquine, and most of the patients (74%) were treated with heparin. . There was a statistically significant difference among the two hospitals in heparin usage rates (P -value< 0.001), while hydroxychloroquine usage rates were comparable (P -value= 0.811) (Table 5) .
