The effects of trained observers (dofficers) and audits during a facility-wide COVID-19 outbreak: A mixed-methods quality improvement analysis

Under Armour - Use of personal protective equipment for simulated CPR of COVID-19 patients: an observational study

BACKGROUND

Personal protective equipment (PPE) protects healthcare workers and patients. Data on guideline compliance on how to dress (donning) or remove (doffing) PPE and the assistance among multiple participants (buddying) are limited. This study assesses the quality of donning, doffing, and buddying of PPE in a simulated medical emergency.

METHOD

Physicians handling a simulated cardiac arrest of a COVID-19 patient. Adjacent to the victim, PPE was available. The appropriateness of PPE choice was assessed by using video recordings, with each individual participant being analyzed from the beginning of the simulation scenario from two perspectives regarding the selection of items during donning and doffing, hygiene aspects, time, and team support (buddying). The primary outcome was the number of participants being appropriately protected, defined as both wearing (a) all PPE items provided, and (b) all PPE items correctly at the time of first patient contact (FPC). Secondary outcomes included the timing of participants being appropriately protected. Statistical analysis was performed using SPSS (version 28). Mann-Whitney test, chi-square test, and linear regression analysis were performed as appropriate.

RESULTS

At first patient contact 21% (91/437) were correctly protected. One or more incorrect PPE items were found in 4% (19/437), whereas 61% (265/437) wore one or more PPE items incorrectly. In 14% (62/437), one or more PPE items were missing. The time interval between donning start and FPC was 66 (55-78) sec. Time to FPC was longer in correctly than in incorrectly protected participants 77 (66-87) vs. 64 (54-75) sec; p < 0.001) and decreased by 7 ± 2 s per PPE item omitted (P = 0.002). Correct doffing was observed in 192/345 (56%), while buddying occurred in 120 participants (27%), indicating that they either assisted other participants in some manner (verbally or physically) or received assistance themselves.

CONCLUSIONS

Our findings imply a need for education in correct and timely PPE donning and doffing. Donning PPE as intended delayed FPC. This and the influence of buddying needs further investigation (German study register number DRKS00023184).

Barriers to healthcare-worker adherence to infection prevention and control practices in British Columbia during the coronavirus disease 2019 (COVID-19) pandemic: A cross-sectional study

OBJECTIVE

The coronavirus disease 2019 (COVID-19) pandemic highlighted the importance of robust infection prevention and control (IPAC) practices to maintain patient and staff safety. However, healthcare workers (HCWs) face many barriers that affect their ability to follow these practices. We identified barriers affecting HCW adherence to IPAC practices during the pandemic in British Columbia, Canada.

DESIGN

Cross-sectional web-based survey.

SETTING

Acute care, long-term care or assisted living, outpatient, mental health, prehospital care, and home care.

PARTICIPANTS

Eligible respondents included direct-care providers and IPAC professionals working in these settings in all health authorities across British Columbia.

METHODS

We conducted a web-based survey from August to September 2021 to assess respondent knowledge and attitudes toward IPAC within the context of the COVID-19 pandemic. Respondents were asked to rate the extent to which various barriers affected their ability to follow IPAC practices throughout the pandemic and to make suggestions for improvement.

RESULTS

The final analysis included 2,488 responses; 36% of respondents worked in acute care. Overall, perceptions of IPAC practice among non-IPAC professionals were positive. The main self-perceived barriers to adherence included inadequate staffing to cover absences (58%), limited space in staff rooms (57%), multibed rooms (51%), and confusing messages about IPAC practices (51%). Common suggestions for improvement included receiving more support from IPAC leadership and clearer communication about required IPAC practices.

CONCLUSIONS

Our findings highlight frontline HCW perspectives regarding priority areas of improvement for IPAC practices. They will inform policy and guideline development to prevent transmission of COVID-19 and future emerging infections.

It provides practical, expert opinion and/or evidence-based answers to frequently asked questions about viral respiratory detection and prevention in the NICU. It was developed by a writing panel of pediatric and pathogen-specific experts who collaborated with members of the HICPAC systematic review writing panel and the SHEA Pediatric Leadership Council to identify questions that should be addressed. The document has been endorsed by SHEA, the American Hospital Association (AHA), The Joint Commission, the Pediatric Infectious Diseases Society (PIDS), the Association for Professionals in Infection Control and Epidemiology (APIC), the Infectious Diseases Society of America (IDSA), and the National Association of Neonatal Nurses (NANN).

Risk and protective factors for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection among healthcare workers: A test-negative case-control study in Québec, Canada

OBJECTIVES

In Québec, Canada, we evaluated the risk of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection associated with (1) the demographic and employment characteristics among healthcare workers (HCWs) and (2) the workplace and household exposures and the infection prevention and control (IPC) measures among patient-facing HCWs.

DESIGN

Test-negative case-control study.

SETTING

Provincial health system.

PARTICIPANTS

HCWs with PCR-confirmed coronavirus disease 2019 (COVID-19) diagnosed between November 15, 2020, and May 29, 2021 (ie, cases), were compared to HCWs with compatible symptoms who tested negative during the same period (ie, controls).

METHODS

Adjusted odds ratios (aORs) of infection were estimated using regression logistic models evaluating demographic and employment characteristics (all 4,919 cases and 4,803 controls) or household and workplace exposures and IPC measures (2,046 patient-facing cases and 1,362 controls).

RESULTS

COVID-19 risk was associated with working as housekeeping staff (aOR, 3.6), as a patient-support assistant (aOR, 1.9), and as nursing staff (aOR, 1.4), compared to administrative staff. Other risk factors included being unexperienced (aOR, 1.5) and working in private seniors' homes (aOR, 2.1) or long-term care facilities (aOR, 1.5), compared to acute-care hospitals. Among patient-facing HCWs, exposure to a household contact was reported by 9% of cases and was associated with the highest risk of infection (aOR, 7.8). Most infections were likely attributable to more frequent exposure to infected patients (aOR, 2.7) and coworkers (aOR, 2.2). Wearing an N95 respirator during contacts with COVID-19 patients (aOR, 0.7) and vaccination (aOR, 0.2) were the measures associated with risk reduction.

CONCLUSION

In the context of the everchanging SARS-CoV-2 virus with increasing transmissibility, measures to ensure HCW protection, including vaccination and respiratory protection, and patient safety will require ongoing evaluation.

Resilience and Protection of Health Care and Research Laboratory Workers During the SARS-CoV-2 Pandemic: Analysis and Case Study From an Austrian High Security Laboratory

The SARS-CoV-2 pandemic has highlighted the interdependency of healthcare systems and research organizations on manufacturers and suppliers of personnel protective equipment (PPE) and the need for well-trained personnel who can react quickly to changing working conditions. Reports on challenges faced by research laboratory workers (RLWs) are rare in contrast to the lived experience of hospital health care workers. We report on experiences gained by RLWs (e.g., molecular scientists, pathologists, autopsy assistants) who significantly contributed to combating the pandemic under particularly challenging conditions due to increased workload, sickness and interrupted PPE supply chains. RLWs perform a broad spectrum of work with SARS-CoV-2 such as autopsies, establishment of virus cultures and infection models, development and verification of diagnostics, performance of virus inactivation assays to investigate various antiviral agents including vaccines and evaluation of decontamination technologies in high containment biological laboratories (HCBL). Performance of autopsies and laboratory work increased substantially during the pandemic and thus led to highly demanding working conditions with working shifts of more than eight hours working in PPE that stressed individual limits and also the ergonomic and safety limits of PPE. We provide detailed insights into the challenges of the stressful daily laboratory routine since the pandemic began, lessons learned, and suggest solutions for better safety based on a case study of a newly established HCBL (i.e., BSL-3 laboratory) designed for autopsies and research laboratory work. Reduced personal risk, increased resilience, and stress resistance can be achieved by improved PPE components, better training, redundant safety measures, inculcating a culture of safety, and excellent teamwork.

Mask use among health care workers and feelings of safety at work pre- and post- COVID-19 vaccine

Background

Correct mask use can prevent the spread of COVID-19 and hospitals require correct mask use. Despite this, there is variation in mask use among health care workers (HCW). Incorrect mask use may lead to increased infections and decreased feelings of safety. The purpose of this study was to determine variation in mask use among HCW as well as feelings of safety from exposure to COVID-19 when around colleagues before and after COVID-19 vaccine roll out.

Methods

This study used direct observation to assess mask use in patient-facing areas before and after COVID-19 vaccine. A staff survey was used to assess feelings of safety.

Results

Over 1,600 mask observations showed increased compliance from 94.6% to 97.5% (P = .001). Three hundred survey responses showed significantly increased feelings of safety (P < .001) after vaccine roll out, and 203 free-text responses with respondant reasoning were categorized into 6 themes.

Discussion

Understanding mask use behaviors and safety attitudes of HCW can help improve policies, workplace culture, and reduce HCW to HCW infections.

Conclusions

Correct mask use was a highly adopted habit in patient-facing areas. The COVID-19 vaccine led to significantly increased feelings of safety among HCW, though the diverging narratives seen in the survey may be helpful to consider when crafting safety interventions.

SARS-CoV-2 outbreak in a Canadian suburban tertiary hospital necessitating full facility closure: a descriptive observational study

BACKGROUND

SARS-CoV-2 can cause outbreaks in community- and hospital-based settings. The aim of this study was to provide a detailed epidemiologic account of a hospital-wide SARS-CoV-2 outbreak and provide a description of case evaluations, transmission networks and the interventions implemented to stem the outbreak.

METHODS

We conducted a retrospective descriptive study of a hospital-wide SARS-CoV-2 outbreak at the Misericordia Community Hospital (Edmonton) from June 21 to Aug. 14, 2020. We reviewed hospital chart, public health and occupational health records to determine demographics, case type (community- or hospital-acquired), need for critical care and outcome for each case linked to the outbreak (patients, hospital staff, and community and patient visitors). We developed detailed transmission networks using epidemiologic data to determine what variables may have contributed to transmission.

RESULTS

Fifty-eight cases of SARS-CoV-2 infection were linked to this hospital outbreak (31 patients, 25 staff members and 2 visitors; 66% female, age range 19-97 years). One patient required critical care, and 11 deaths were recorded (all among inpatients). Most cases were hospital-acquired (91%), and 28% were asymptomatic at the time of diagnosis. The outbreak was composed of 2 clusters driven by protective equipment breaches, premature removal of precautions, transmission in small staff quarters and infection of a staff member after exposure to a wandering patient with dementia and asymptomatic, undetected SARS-CoV-2 infection.

INTERPRETATION

A detailed epidemiologic review of this hospital-wide outbreak shows that a SARS-CoV-2 outbreak can involve complex transmission chains and clusters. Multipronged bundled approaches, aggressive contact tracing, and patient and staff prevalence screening are important to help bring such outbreaks under control, along with ongoing vigilance in detecting delayed cases.

Building a personal protective equipment monitor team as part of a comprehensive COVID-19 prevention strategy

We instituted Personal Protective Equipment (PPE) Monitors as part of our care of COVID-19 patients in high-risk zones. PPE Monitors aided health care personnel (HCP) in donning and doffing, which contributed to nearly zero transmission of COVID-19 to HCP, despite their care of over 1400 COVID-19 patients.

[Infection prevention and control for COVID-19 in healthcare settings]

In healthcare facilities, the initial response to emerging and reemerging infectious diseases, including COVID-19, requires systematic management. The first step is to establish an initial risk assessment and subsequent response flow, using a combination of triage and clinical examination for patients. Screening tests are performed for the early diagnosis of asymptomatic patients who are judged to be at low risk in the initial assessment. However, regardless of the test results, subsequent patient care should be taken cautiously to avoid inadequate initial evaluation at the time of admission, follow-up of symptoms and infection control measures after admission. The basic principle is standard precautions, with particular emphasis on compliance with hand hygiene. Universal masking for preventing transmission from asymptomatic/pre-symptomatic patients and reducing droplet emission and inhalation become the new essential precaution. For suspected/confirmed patients with COVID-19, surgical mask or N95 mask, gloves, gown, eye protection, and cap are basically used. The policy for personal protective equipment is made based on the medical environment of each facility. A negative pressure room is not always required but should be considered in high-risk environments, if possible. While the risk of transmission from the surface environment in a standard healthcare delivery system is limited, a continuous review of the facility environment is expected, considering the importance of ventilation.
