How to rapidly design and operationalise PPE donning and doffing areas for a COVID-19 care facility: quality improvement initiative

Tools and methods for evaluating the change to health service delivery due to pandemics or other similar emergencies: A rapid evidence review

The novel coronavirus, SARS-CoV-2 and its associated disease COVID-19, were declared a pandemic in March 2020. Countries developed rapid response activities within their health services to prevent spread of the virus and protect their populations. Evaluating health service delivery change is vital to assess how adapted practices worked, particularly during times of crisis. This review examined tools and methods that are used to evaluate health service delivery change during pandemics and similar emergencies. Five databases were searched, including PubMed, CENTRAL, Embase, CINAHL, and PsycINFO. The SPIDER tool informed the inclusion criteria for the articles. Articles in English and published from 2002 to 2020 were included. Risk of bias was assessed using the Mixed-Methods Appraisal Tool (MMAT). A narrative synthesis approach was used to analyse the studies. Eleven articles met the inclusion criteria. Many evaluation tools, methods, and frameworks were identified in the literature. Only one established tool was specific to a particular disease outbreak. Others, including rapid-cycle improvement and PDSA cycles were implemented across various disease outbreaks. Novel evaluation strategies were common across the literature and included checklists, QI frameworks, questionnaires, and surveys. Adherence practices, experience with telehealth, patient/healthcare staff safety, and clinical competencies were some areas evaluated by the tools and methods. Several domains, including patient/practitioner safety and patient/practitioner experience with telemedicine were also identified in the studies.

Transmission and Risk Factors of COVID-19 among Health Care Workers

Coronavirus disease 2019 (COVID-19) poses a significant occupational risk factor to health care workers (HCWs). As in previous events, this occupational risk amplifies and compounds the adverse impact of the pandemic. We conducted a narrative review summarizing risk factors associated with severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) transmission in HCWs. We searched for original observational studies (including case-control, cross-sectional, prospective and retrospective cohorts) using PubMed, Scopus, and Google Scholar. A total of 22 articles were reviewed, including eligible English articles published between April 2020 and May 2022. Job category, work environment, personal protective equipment (PPE) noncompliance, lack of PPE awareness and training, unvaccinated status, and competing community and household exposures were identified as risk factors for SARS-CoV-2 transmission among HCWs. Effective measures to protect HCWs from SARS-CoV-2 need to account for the identified occupational risk factors. Identifying and understanding COVID-19 risk factors among HCWs must be considered a public health priority for policy makers to mitigate occupational and community transmission in current and future epidemics.

Assessing efficacy of instructor based orientation to donning doffing protocols and modifications to doffing area infrastructure in reducing SARS-CoV-2 infection among Doctors assigned to COVID-19 patient care

Background

We assess the efficacy of orientation programmes for doctors of proper donning, doffing techniques for personal protective equipment (PPE) and safe practices inside the COVID-19 hospital in reducing the COVID-19 infection rate among doctors.

Methods

A total of 767 resident doctors and 197 faculty visits on weekly rotation were recorded over a six month period. Doctors were guided through orientation sessions before their entry into the COVID-19 hospital from 1 August 2020.The infection rate among doctors was used to study the efficacy of the programme. McNemars Chi-square test was used to compare the infection rate in the two groups before and after orientation sessions were commenced.

Discussion

A statistically significant reduction in SARS-CoV-2 infection was seen among resident doctors after orientation programmes and infrastructure modification (3% vs 7.4%, p=0.03). Twenty-eight of 32 (87.5%) doctors who tested positive developed asymptomatic to mild infection. The infection rate was 3.65% and 2.1% among residents and faculty respectively. There was no mortality recorded.

Conclusion

Orientation programme for healthcare workers for PPE donning and doffing protocols with practical demonstration and trial of PPE usage can significantly reduce COVID-19infection. Such sessions should be mandatory for all workers on deputation in designated area for Infectious Diseases and in pandemic situations.

Doffing Corridor: Establishing Expedited High-Volume Doffing With Exposure Reduction to Contaminated Personal Protective Equipment (PPE) in a COVID-19 Hospital in India

Background Considering the virulent nature of the COVID-19, the safety of healthcare workers (HCW) became a challenge for hospital administrators. Wearing a personal protective equipment (PPE) kit, called donning, which can be easily done by the help of another staff. But correctly removing the infectious PPE kit (doffing) was a challenge. The increased number of HCWs for COVID-19 patient care raised the opportunity to develop an innovative method for the smooth doffing of PPEs. Objective We aimed to design and establish an innovative PPE doffing corridor in a tertiary care COVID-19 hospital during the pandemic in India with a heavy doffing rate and minimize the COVID-19 virus spread among healthcare workers. Methodology A prospective, observational cohort study at the COVID-19 hospital, Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India, was conducted from July 19, 2020, to March 30, 2021. The time taken for PPE doffing process of HCWs was observed and compared between the doffing room and doffing corridor. The data was collected by a public health nursing officer using Epicollect5 mobile software and Google forms. The following parameters, like grade of satisfaction, time and volume of doffing, the errors in the steps of doffing, rate of infection, were compared between the doffing corridor and the doffing room. The statistical analysis was done by the use of SPSS software. Result 'Doffing corridor' decreased the overall doffing time by 50% compared to the initial doffing room. The doffing corridor solved the purpose of accommodating more HCWs for PPE doffing and an overall saving of 50% time. Fifty-one percent of HCWs rated the satisfaction rate as Good in the grading scale. The errors in the steps of doffing that occurred in the doffing process were comparatively lesser in the doffing corridor. The HCWs who doffed in the doffing corridor were three times less likely to get self-infection than the conventional doffing room. Conclusion Since COVID-19 was a new pandemic, the healthcare organizations focused on innovations to combat the spread of virus. One of these was an innovative doffing corridor to expedite the doffing process and decrease the exposure time to the contaminated items. The doffing corridor process can be considered at a high-interest rate to any hospital dealing with infectious disease, with high working satisfaction, less exposure to the contagion, and less risk of infection.

Modelling the impacts of COVID-19 on nurse workload and quality of care using process simulation

Higher acuity levels in COVID-19 patients and increased infection prevention and control routines have increased the work demands on nurses. To understand and quantify these changes, discrete event simulation (DES) was used to quantify the effects of varying the number of COVID-19 patient assignments on nurse workload and quality of care. Model testing was based on the usual nurse-patient ratio of 1:5 while varying the number of COVID-19 positive patients from 0 to 5. The model was validated by comparing outcomes to a step counter field study test with eight nurses. The DES model showed that nurse workload increased, and the quality of care deteriorated as nurses were assigned more COVID-19 positive patients. With five COVID-19 positive patients, the most demanding condition, the simulant-nurse donned and doffed personal protective equipment (PPE) 106 times a shift, totaling 6.1 hours. Direct care time was reduced to 3.4 hours (-64% change from baseline pre-pandemic case). In addition, nurses walked 10.5km (+46% increase from base pre-pandemic conditions) per shift while 75 care tasks (+242%), on average, were in the task queue. This contributed to 143 missed care tasks (+353% increase from base pre-pandemic conditions), equivalent to 9.6 hours (+311%) of missed care time and care task waiting time increased to 1.2 hours (+70%), in comparison to baseline (pre-pandemic) conditions. This process simulation approach may be used as potential decision support tools in the design and management of hospitals in-patient care settings, including pandemic planning scenarios.

Compliance to donning and doffing of personal protective equipment among dental healthcare practitioners during the coronavirus pandemic: a quality improvement plan, do, study and act (PDSA) Initiative

Introduction

With the emergence of SARS-Cov-2, the Centers for Disease Control and Prevention (CDC) defined mandatory guidelines for donning and doffing personal protective equipment (PPE) among dental healthcare professionals. The study’s objective was to improve the compliance of the donning and doffing protocols for PPE among dental practitioners by the Plan, Do, Study, and Act (PDSA) cycle.

Materials and methods

A quasi-experimental study was conducted on a sample of dental healthcare professionals using the non-probability purposive technique. In the first planning stage, compliance with CDC-approved donning and doffing was assessed on the clinical premises. In the second stage, an educational session was arranged with all the healthcare professionals to explain stepwise guidelines of donning and doffing to improve the quality of donning and doffing compliance. In the third stage, improvement in the quality outcome was then assessed after the session. Data were normally distributed. Qualitative variables for all the steps of donning and doffing are reported as frequency and percentages. Pareto charts were made to assess the non-compliance rate for donning and doffing protocols among dental healthcare professionals.

Results

There was an improvement of 44.55% in the hand hygiene practices before wearing the PPE after the second step of the PDSA cycle. A percentage improvement of 7.4% was recorded for removing jewellery, wearing the gown and wearing a surgical cap. No improvement was seen in securing the mask/ respirator ties, washing hands after wearing the respirator, placing the goggles or face shield practices.

Conclusions

PDSA cycle improved the overall compliance to PPE donning and doffing practices. Most of the protocols were followed by the dental healthcare professionals; however, some of them remained the same or worsened due to ease in SARS-CoV 2 restrictions.

Creating a Safety Officer Program to Enhance Staff Safety During the Care of COVID-19 Patients

Staff safety is paramount when managing an infectious disease event. However, early data from the COVID-19 pandemic suggested that staff compliance with personal protective equipment and other safety protocols was poor. In response to patient surges, many hospitals created dedicated "biomode" units to provide care for patients infected with SARS-CoV-2, the virus that causes COVID-19. To enhance staff safety on biomode units and during patient transports, our hospital created a safety officer/transport safety officer (SO/TSO) program. The first SOs/TSOs were nurses, clinical technicians, and other support staff who were redeployed from their home units when the units closed during the initial surge. During subsequent COVID-19 surges, dedicated SOs/TSOs were hired to maintain the program. SOs/TSOs provided just-in-time personal protective equipment training and helped staff safely enter and exit COVID-19 clinical units. SOs/TSOs participated in the transport of over 1,000 COVID-19 patients with no safety incidents reported. SOs/TSOs conducted safety audits throughout the hospital and observed 86% compliance with COVID-19 precautions across 32,500 activities. During contact tracing of frontline staff who became infected with SARS-CoV-2, potential deviations from COVID-19 precautions were identified in only 7.7% of cases. The SO/TSO program contributed to a culture of safety in the biomode units and helped to enhance infection prevention throughout the hospital. This program can serve as a model for other health systems during the response to the current pandemic and during future infectious disease threats.

Impact of Face-to-Face Teaching in Addition to Electronic Learning on Personal Protective Equipment Doffing Proficiency in Student Paramedics: Randomized Controlled Trial

Personal protective equipment doffing is a complex procedure that needs to be adequately performed to prevent health care worker contamination. During the COVID-19 pandemic, junior health care workers and students of different health care professions who had not been trained to carry out such procedures were often called upon to take care of infected patients. To limit direct contact, distance teaching interventions were used, but different trials found that their impact was rather limited. We therefore designed and carried out a randomized controlled trial assessing the impact of adding a face-to-face intervention using Peyton's four-step approach to a gamified e-learning module. Sixty-five student paramedics participated in this study. The proportion of doffing sequences correctly performed was higher in the blended learning group (33.3% (95%CI 18.0 to 51.8) versus 9.7% (95%CI 2.0 to 25.8), p = 0.03). Moreover, knowledge and skill retention four to eight weeks after the teaching intervention were also higher in this group. Even though this study supports the use of a blended learning approach to teach doffing sequences, the low number of student paramedics able to adequately perform this procedure supports the need for iterative training sessions. Further studies should determine how often such sessions should be carried out.

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

Background

In response to a facility-wide COVID-19 outbreak, our tertiary acute care hospital implemented an evidence-based bundle of infection control practices including the use of audits and trained observers “dofficers” to provide real-time constructive feedback.

Methods

We trained furloughed staff to perform the role of dofficer. They offered support and corrective feedback on proper PPE use and completed 21-point audits during a 4-week intervention period. Audits tracked appropriate signage, placement and availability of supplies (equipment), correct PPE use, enhanced environmental cleaning, along with cohorting and social distancing rates. Audit data was used to provide weekly quality improvement reports to units.

Results

Nine hundred and sixty two separate audits recorded 36,948 observations, over 7,696 observer-hours. The most common errors were with environmental cleaning and PPE use; the least common were with regards to equipment availability and cohorting and social distancing. Mean error rates decreased from 9.81% to 2.88% (P < .001). The largest reduction, 22.57%, occurred in the category of PPE doffing errors.

Conclusions

Dofficer led audits effectively identified areas for improvement. Feedback through weekly reports and real-time correction of PPE errors by dofficers led to statistically significant improvements; however, error rates remained high. Further research is needed establish if these relationships are causal.

Efficiency and Teamwork in Emergency Departments: Perception of Staff on Design Interventions

OBJECTIVES

The goal of this study is twofold: (1) identifying design strategies that enhance efficiency and support teamwork in emergency departments (EDs) and (2) identifying design features that contribute to the spread of COVID-19, based on staff perception.

BACKGROUND

Due to increasing ED visits annually, an efficient work environment has become one of the main concerns in designing EDs. According to the literature, an efficient work environment and teamwork improve healthcare outcomes and positively impact staff satisfaction. During the COVID-19 pandemic, EDs faced various changes such as workflow and space usage. Few studies explored staff perceptions about the influence of design features on efficiency, teamwork, and the COVID-19 spread.

METHOD

An online survey with 14 open- and closed-ended questions was distributed among ED staff members to collect data about unit design features that impact efficiency, teamwork, and the COVID-19 spread.

RESULTS

The central nursing station was one of the preferred configurations that increased efficiency and teamwork in EDs. Decentralizing disposal rooms in small-size EDs and decentralizing the medication room in large-size EDs with more than 65 exam rooms can decrease staff walking steps. Flexibility to expand treatment spaces on demand, one-way track circulation path, and changing the air pressure in COVID-19 treatment areas were some of the staff suggestions for future EDs.

CONCLUSION

The findings of this study contribute to the body of knowledge that EDs' physical environments can impact efficiency and teamwork among staff and, consequently, healthcare outcomes. Compartmentalization of the ED layout can reduce the spread of COVID-19.

Impact of Face-to-Face Teaching in Addition to Electronic Learning on Personal Protective Equipment Doffing Proficiency in Student Paramedics: Protocol for a Randomized Controlled Trial

Background

The COVID-19 pandemic has brought attention to the importance of correctly using personal protective equipment (PPE). Doffing is a critical phase that increases the risk of contamination of health care workers. Although a gamified electronic learning (e-learning) module has been shown to increase the adequate choice of PPE among prehospital personnel, it failed to enhance knowledge regarding donning and doffing sequences. Adding other training modalities such as face-to-face training to these e-learning tools is therefore necessary to increase prehospital staff proficiency and thus help reduce the risk of contamination.

Objective

The aim of this study is to assess the impact of the Peyton 4-step approach in addition to a gamified e-learning module for teaching the PPE doffing sequence to first-year paramedic students.

Methods

Participants will first follow a gamified e-learning module before being randomized into one of two groups. In the control group, participants will be asked to perform a PPE doffing sequence, which will be video-recorded to allow for subsequent assessment. In the experimental group, participants will first undergo face-to-face training performed by third-year students using the Peyton 4-step approach before performing the doffing sequence themselves, which will also be video-recorded. All participants will then be asked to reconstruct the doffing sequence on an online platform. The recorded sequences will be assessed independently by two investigators: a prehospital emergency medicine expert and an infection prevention and control specialist. The assessors will be blinded to group allocation. Four to eight weeks after this first intervention, all participants will be asked to record the doffing sequence once again for a subsequent skill retention assessment and to reconstruct the sequence on the same online platform to assess knowledge retention. Finally, participants belonging to the control group will follow face-to-face training.

Results

The study protocol has been presented to the regional ethics committee (Req-2020-01340), which issued a declaration of no objection as such projects do not fall within the scope of the Swiss federal law on human research. Study sessions were performed in January and February 2021 in Geneva, and will be performed in April and June 2021 in Bern.

Conclusions

This study should help to determine whether face-to-face training using the Peyton 4-step approach improves the application and knowledge retention of a complex procedure when combined with an e-learning module.

Management of a Hospital-Wide COVID-19 Outbreak Affecting Patients and Healthcare Workers

To the best of our knowledge, here, we describe the first hospital-wide outbreak of SARS-CoV-2 that occurred in Germany in April 2020. We aim to share our experience in order to facilitate the management of nosocomial COVID-19 outbreaks in healthcare facilities. All patients and hospital workers were screened for SARS-CoV-2 repeatedly. An infection control team on the side was installed. Strict spatial separation of patients and intensified hygiene training of healthcare workers (HCW) were initiated. By the time of reporting, 26 patients and 21 hospital workers were infected with a cluster of cases in the geriatric department. Fourteen patients developed COVID-19 consistent symptoms and five patients with severe pre-existing medical conditions died. The outbreak was successfully contained after intensified infection control measures were implemented and no further cases among patients were detected over a period of 14 days. Strict application of standard infection control measures proved to be successful in the management of nosocomial SARS-CoV-2 outbreaks.
