RESUMEN
The Hajj is an annual mass gathering of people in Makkah, Saudi Arabia. Respiratory infections are common due to their potential for rapid spread in crowded settings. There is a lack of data regarding the effectiveness of face masks in preventing respiratory tract infections (RTIs), specifically during Hajj. We systematically searched PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials until July 3, 2023 for studies comparing the incidence or prevalence of RTIs in those who used any face mask during Hajj compared with no mask. Risk ratio (RRs) and 95% CIs were calculated using either a fixed or random-effect model, depending on the heterogeneity. A comprehensive analysis encompassed 10 studies involving 5007 participants. The overall RR favored wearing masks over not wearing masks regarding the incidence of RTIs; however, the difference was not statistically significant (RR = 0.78; 95% CI = 0.55-1.10; P = 0.16). A significantly lower incidence of RTIs was found in those wearing masks most of the time versus intermittently (RR = 0.59; 95% CI = [0.38-0.94; P = 0.02). In subgroup analyses, there was no difference between wearing masks and not wearing masks across different study designs (cohort/case-control), different groups (pilgrims/healthcare workers), and different years of Hajj, except from 2000 to 2008, when there was a significant difference favoring wearing face masks. This meta-analysis found wearing masks most of the time was associated with significantly lower risk of RTIs than wearing it intermittently.
RESUMEN
Corona virus disease 2019 is a global pandemic, which affects around 2million individuals with a high death rate that exceeds 90,000 death cases across the globe. The Saudi Heart Association and the national cardiopulmonary resuscitation committee developed a taskforce to discuss the magnitude of clinical situation and CPR management on COVID-19 patients in a prehospital and in-hospital settings. Meanwhile, the taskforce aims to develop a nation-wide clinical guidance to be used by health care workers and untrained laypersons to resuscitate COVID-19 suspected and diagnosed patients.
RESUMEN
BACKGROUND: Millions of Muslims from across the world gather annually to perform pilgrimage. This can import unusual communicable diseases such as Ebola. Communicable diseases with a high risk of mortality necessitate special training to master the required competency to avert transmission of infections. The efficacy of simulation-based training (SBT) has been shown in such circumstances. OBJECTIVE: We sought to develop an SBT program in Ebola Personal Protective Equipment (PPE) for all healthcare workers (HCWs). METHODS: We conducted a quasi-experimental study at the clinical skills and simulation center at the King Abdulaziz University. An interdisciplinary committee was formed to develop this program in three stages. Pre-intervention: Needs assessment "Diagnostic drill"; we conducted in-situ simulation in the emergency department (ED). High-fidelity simulator (HFS) was used as a suspected Ebola case to assess HCWs' competency of PPE. We used a checklist that was developed in accordance with the national and international guidelines. We then conducted "Train the Trainer in Ebola PPE" course to develop potential instructors. INTERVENTION: PPE competency SBT courses. This involved focusing on trainees to be skilled in Ebola PPE and becoming trained observers using skill stations and Ebola scenario with HFS, followed by debriefing. All courses gathered participants' evaluations, pre, and post-tests. Post-intervention: In-situ simulation in the ED two months later that was similar to the diagnostic drill. RESULTS: Pre-intervention: 7 HCWs were involved in the drill, the average score was 37% of the checklist items. For train the trainer, 19 potential PPE instructors attended the program; of them, 65% were female and 35% male, and 6 were physicians and 13 nurses. Average pre and post-tests scores were 72% and 86%, respectively. INTERVENTION: 10 PPE courses that were attended by 179 HCWs; of them, 67% were female and 33% male, and 52 were physicians, 112 nurses, and 15 others. Pre and posttests were 67% (57-75%) and 85% (81-91%), respectively, with a p-value<0.01. Post-intervention: Post Program drill's average score was 86% of the checklist items (37% in diagnostic drill). CONCLUSIONS: Using SBT could be an effective method of developing competent HCWs in Ebola PPE.
