Medical Masks Versus N95 Respirators for Preventing COVID-19 Among Health Care Workers : A Randomized Trial.

BACKGROUND: It is uncertain if medical masks offer similar protection against COVID-19 compared with N95 respirators. OBJECTIVE: To determine whether medical masks are noninferior to N95 respirators to prevent COVID-19 in health care workers providing routine care. DESIGN: Multicenter, randomized, noninferiority trial. (ClinicalTrials.gov: NCT04296643). SETTING: 29 health care facilities in Canada, Israel, Pakistan, and Egypt from 4 May 2020 to 29 March 2022. PARTICIPANTS: 1009 health care workers who provided direct care to patients with suspected or confirmed COVID-19. INTERVENTION: Use of medical masks versus fit-tested N95 respirators for 10 weeks, plus universal masking, which was the policy implemented at each site. MEASUREMENTS: The primary outcome was confirmed COVID-19 on reverse transcriptase polymerase chain reaction (RT-PCR) test. RESULTS: In the intention-to-treat analysis, RT-PCR-confirmed COVID-19 occurred in 52 of 497 (10.46%) participants in the medical mask group versus 47 of 507 (9.27%) in the N95 respirator group (hazard ratio [HR], 1.14 [95% CI, 0.77 to 1.69]). An unplanned subgroup analysis by country found that in the medical mask group versus the N95 respirator group RT-PCR-confirmed COVID-19 occurred in 8 of 131 (6.11%) versus 3 of 135 (2.22%) in Canada (HR, 2.83 [CI, 0.75 to 10.72]), 6 of 17 (35.29%) versus 4 of 17 (23.53%) in Israel (HR, 1.54 [CI, 0.43 to 5.49]), 3 of 92 (3.26%) versus 2 of 94 (2.13%) in Pakistan (HR, 1.50 [CI, 0.25 to 8.98]), and 35 of 257 (13.62%) versus 38 of 261 (14.56%) in Egypt (HR, 0.95 [CI, 0.60 to 1.50]). There were 47 (10.8%) adverse events related to the intervention reported in the medical mask group and 59 (13.6%) in the N95 respirator group. LIMITATION: Potential acquisition of SARS-CoV-2 through household and community exposure, heterogeneity between countries, uncertainty in the estimates of effect, differences in self-reported adherence, differences in baseline antibodies, and between-country differences in circulating variants and vaccination. CONCLUSION: Among health care workers who provided routine care to patients with COVID-19, the overall estimates rule out a doubling in hazard of RT-PCR-confirmed COVID-19 for medical masks when compared with HRs of RT-PCR-confirmed COVID-19 for N95 respirators. The subgroup results varied by country, and the overall estimates may not be applicable to individual countries because of treatment effect heterogeneity.

Telephone triage in midwifery practice: a mixed methods study

Childbearing women's concerns are evaluated by midwives during telephone triage to determine a need for advice or further assessment. Individual maternity services rather than general call centres manage these calls from women. This important practice contributes to the provision of timely and appropriate healthcare, further evidenced during the Covid-19 pandemic. Little is known about midwives' telephone triage practises. The aim of this study was to explore practising midwives' views, experiences, and practices of telephone triage. A two-phased sequential mixed method design was used encompassing an online survey and one-on-one interviews. Survey data underwent descriptive statistical analyses using SPSS V24. Transcribed verbatim interviews were analysed thematically. Survey respondents totalled (n =230) and interview participants (n =14). Integrated findings suggest telephone triage is an unacknowledged practice that increases midwives' workloads. Midwives reported they manage thousands of calls each year with competing workload interests, environmental distractions, and inconsistent workplace processes. The need for experience and time to develop specific skills to safeguard 'getting it right' and 'meeting expectations' was identified. Considerable time is needed to respond to calls and provide quality care to women. Workplace environments can impede information collected and decision-making. Telephone triage was perceived as 'risky business' with intrinsic clinical, legal and professional risk that for some may evoke anxiety. This study emphasises variations in service provision, midwives' practice, and management of telephone triage. Empathy, high-level interpersonal and communication skills are needed. Recommendations from midwives included training and support to develop skills in telephone triage. With evolving technologies and communication platforms, these findings establish a basis for midwives and health services when providing care from a distance. Providing quality, effective, and safe care to women during telephone triage, midwives need clear governance, support to develop skills, time to triage, and suitable work environments.

A new survey tool for evaluating pandemic preparedness in health services.

BACKGROUND: Rapid decision-making with limited resources and prior research to draw upon posed challenges for health service leaders globally when preparing for COVID-19. How do health services prepare for a pandemic and evaluate if the preparation has been effective? This study aimed to explore health workers' perceptions and knowledge regarding preparedness for COVID-19 at a regional health service in Australia. METHODS: A 32-item online survey was developed to evaluate preparedness across five scales: 1) Clinical, 2) Communication, 3) Environment, 4) Human Resources, and 5) General Preparedness. Data were analyzed using parametric and non-parametric statistics and qualitative content analysis. RESULTS: Ninety-three employees completed the survey, with most working in clinical roles (58.1%). Respondents largely felt the health service was well-prepared (84.0%) and they were personally prepared (74.4%) to respond to COVID-19. Clinical and communication scale scores varied by role type. Respondents faced personal risk and resource shortages impacted their sense of safety; others felt adequately supported. CONCLUSIONS: A coordinated "whole hospital response", accessible and inclusive communication, education, adequate resourcing, and employee wellbeing supports are necessary when preparing health services for sentinel events. This survey tool offers health services an approach to evaluating pandemic preparation. Continued advocacy for resources and wellbeing needs of health workers is paramount in future preparations.

Primary healthcare clinicians.

The objective of the study was to measure implementation of telehealth for client consultations from Allied Health and Community Health clinicians' perspectives during the COVID-19 pandemic. Purposeful sampling was used to invite allied and community health clinicians to complete the survey. An online survey design, underpinned by normalisation process theory, utilising the NoMAD tool, which consists of 19 implementation assessment items. Descriptive statistics are reported. A 66% (n=24) response rate was obtained. Fifty-two percent indicated they were using telehealth for the first time. Despite the rapid implementation of telehealth for client consultations due to the pandemic crisis, participants reported positive perceptions of the use of telehealth when measured using the NoMAD. Fifty-eight percent (n=14) of respondents agreed or strongly agreed that telehealth will become a normal part of their work. Despite unplanned and under-resourced implementation of telehealth, Allied Health and Community Health clinicians reported very positive perceptions. However, further education and training to ensure 'normalisation' of this model may be required.
