Compliance of healthcare workers to the proper use of personal protective equipment during the first wave of COVID-19 pandemic.

BACKGROUND: In limited resource settings, compliance to proper personal protective equipment (PPE) use is challenging. This study aims to characterize the pattern of PPE use among healthcare workers (HCWs) during the first wave of coronavirus diseases-2019 (COVID-19) in Egypt and to determine the factors associated with compliance to the proper use of PPE. METHODS: A cross-sectional study was conducted among Egyptian HCWs using an online self-administered questionnaire. Participants were classified as "Compliant" or "Non-compliant" according to their score. RESULTS: A total of 404 responses were analyzed, with a mean age of 36.6 ± 8.4 years, and 56.4% were females. Non-compliant HCWs represented 53.2% of participants. The majority reported shortage in N95 respirators (91.3%) and practiced extended PPE use (88.1%). Better compliance to proper PPE use was reported: females (51.3%, p = 0.05), Physicians (54.2 %, p = 0.005), medical specialities (34.7 %, p < 0.001), <10 years' work experience (42.9%, p = 0.05) and working > eight hours/day (71.3%, p < 0.001). The significant predictors for compliance were; receiving prior training on the proper use of PPE (OR: 4.59, CI: 2.22-9.47, p ≤ 0.001), exposure to COVID-19 patients (OR: 2.75, CI: 1.19-6.35, p = 0.02) and performing procedures that pose HCWs at a high risk of exposure to Severe Acute Respiratory Syndrome Coronavirus 2 (OR: 2.21, CI: 1.04-4.71, p = 0.04). The high percentage of non-compliant HCWs turns on a warning signal. Increase the availability of PPE, prioritize their use, provide more focus on training of HCWs and monitor their compliance is highly recommended.

Role of suPAR and Lactic Acid in Diagnosing Sepsis and Predicting Mortality in Elderly Patients.

This study investigated the diagnostic value of soluble urokinase plasminogen activator receptor (suPAR) and serum lactate in elderly patients with sepsis and evaluated their capacity to predict mortality and their correlation to Sequential Organ Failure Assessment (SOFA) score. The study included 80 participants, divided into two groups: 40 cases (mean age, 68.9 ± 5.9) admitted to the intensive care unit and 40 healthy controls (mean age, 67.1 ± 6.2). Elderly patients with sepsis had significantly higher levels of serum suPAR and lactic acid compared to healthy controls. Receiver operating characteristic (ROC) curve analysis showed that suPAR (cutoff value, ≥4.37 ng/ml) has higher area under the curve (AUC) than lactic acid (cutoff value, ≥1.95 mmol/l) for diagnosing sepsis. Serum lactate has superior prognostic value compared to suPAR with AUC of 0.82 (cutoff value, 2.2 mmol/l) and 0.72 (cutoff value, 6.3 ng/ml), respectively. The diagnostic power of combined usage of suPAR and lactate serum concentrations showed AUC of 0.988 (95% confidence interval 0.934 to 1.0). The combination of both biomarkers either together or with SOFA score may serve as a useful guide to patients who need more intensive resuscitation.
