Surgical helmet systems in total joint arthroplasty: assessment of hood sterility and donning technique

BACKGROUND

The incidence of prosthetic joint infection (PJI) is increasing, coincident with the rising volume of joint arthroplasty being performed. With recent controversy regarding the efficacy of surgical helmet systems (SHS) in preventing infection, the focus has turned to the correct donning techniques and usage of surgical hoods. The aim of this study was to compare the bacterial contamination of the operating surgeon's gloves after two common donning techniques of SHS hoods. We also evaluated the baseline sterility of the SHS hoods at the beginning of the procedure.

METHODS

The bacterial contamination rate was quantified using colony-forming units (CFUs), with 50 trials performed per donning technique. Samples were cultured on 5% Columbia blood agar in ambient air at 37 °C for 48 h and all subsequent bacterial growth was identified using a MALDI-TOF mass spectrometer. In Group 1, the operating surgeon donned their colleague's hood. In Group 2, the operating surgeon had their hood applied by a non-scrubbed colleague. After each trial, the operating surgeon immediately inoculated their gloves onto an agar plate. The immediate sterility of 50 SHS hoods was assessed at two separate zones-the screen (Zone 1) and the neckline (Zone 2).

RESULTS

There was no significant difference in contamination rates between the two techniques (3% vs. 2%, P = 0.99) or between right and left glove contamination rates. Immediately after donning, 6/50 (12%) of SHS hoods cultured an organism. Contamination rates at both the face shield and neckline zones were equivalent. The majority of bacteria cultured were Bacillus species.

DISCUSSION

We found no significant difference in the operating surgeon's glove contamination using two common SHS hood-donning techniques when they were performed under laminar airflow with late fan activation. We suggest the SHS hood should not be assumed to be completely sterile and that gloves are changed if it is touched intraoperatively.

Early Doffing among Frontline Healthcare Workers Working in the COVID Areas in Resource-Limited Settings: Lessons Learned and Interventions Taken

Background

In the fight against the pandemic, personal protective equipment (PPE) has played a vital role. However, working with PPE has its own difficulties and problems. The aim of this study was to find out the reasons of early doffing, that is, in doffing in emergency situations before the shift among healthcare workers (HCWs) working in PPE in the COVID areas in resource-limited settings.

Methods

This cross-sectional, survey-based study was carried out on healthcare workers involved in direct care of patients with COVID-19 in tertiary care COVID center, India. The questionnaire was sent as a Google form through email and social media platforms like WhatsApp and Facebook. The data was reported as the mean ± SD for continuous variables and as the percentage for categorical variables.

Findings

Among 252 healthcare workers who participated in the survey, 145 (57.5%) participants doffed early on 300 occasions. Out of these 145, 50% doffed early only once and rest doffed early multiple times. The most common reason of early doffing was found to be breach in PPE (15.33%) followed by fogging (14%) and headache (12%), and most commonly, breach was in mask or coverall/gown (32.6% each).

Conclusion

Although PPE decreases the risk of infection, it is challenging for HCWs to work in PPE leading to instances of early doffing. The most common reason for early doffing in our study was the breach in PPE and the most common component of breach was found to be mask and coverall/gown. Therefore, we suggest that the proper sizes of the PPE should be made available and proper training in donning should be imparted to HCWs working in PPE.

Can "YouTube" help healthcare workers for learning accurate donning and doffing of personal protective equipments?

INTRODUCTION

Healthcare workers have a high risk of cross-infection during the care of Covid-19 cases. Personal protective equipment can reduce the risk. However, healthcare workers must be trained for the proper use of personal protective equipment to decrease exposure risk. This study aimed to investigate whether videos available on YouTube, presenting procedures of donning and doffing personal protective equipment, can be a useful learning resource for healthcare workers.

METHODS

A search of YouTube was conducted using the keywords "Covid-19, personal protective equipment, donning, doffing". Two investigators reviewed each video and collected the basic video information. Total videos were assessed independently as educationally useful and non-useful categories using a valid tool. The relationship of each video's usefulness with viewers' preferences and the upload source were analyzed.

RESULTS

A total of 300 videos were assessed; 66 (22%) fulfilled the inclusion criteria. Total video scores of educationally useful videos were higher than non-useful ones; the differences were significant. Healthcare/government agencies and hospitals mostly created educationally useful videos, e-learning platforms, and individuals mainly created non-useful videos. Significant correlations were observed between the video's usefulness and the total view and views per day.

CONCLUSIONS

During a pandemic, YouTube might be a resource for learning donning and doffing of personal protective equipment for healthcare workers if an appropriate selection process applied for determining educationally useful videos.

Personal protective equipment in Covid-19: Evidence-based quality and analysis of YouTube videos after one year of pandemic

Background

The correct use of personal protective equipment (PPE) during the Covid-19 pandemic is mandatory to minimize the contagion risk. The current study aimed to evaluate quality information of YouTube videos on PPE use during the pandemic.

Methods

Using Google Trend tool, the frequency of worldwide YouTube and Google searches for “donning and doffing” was examined. We queried YouTube with terms related to donning and doffing of PPE. Validated quality information assessment tools were used.

Results

From the December 1, 2019 to the January 31, 2021, according to YouTube and Google searches, both peaks occurred in April 2020 (69.5% and 72.0%, respectively). Of all videos, 144 were eligible for the analyses. According to misinformation tool, 90 (62.5%) videos contained inaccuracies. The median DISCERN Section 1 ranged from 3 to 5. The median DISCERN Section 3 was 4. According to Global Quality Score, 8.3% (n = 12), 14.6% (n = 21), 22.9% (n = 33), 30.6% (n = 44) and 23.6% (n = 34) were classified as poor, partially poor, moderate, partially good and excellent quality videos, respectively.

Conclusions

Nowadays, YouTube may be recommended as a reliable source of information. Nevertheless, a not negligible number of videos contained inaccuracies. Future authors should improve videos contents to provide more complete information.

Knowledge and practice of Protective Personal Equipment (PPE) among healthcare providers in Saudi Arabia during the early stages of COVID-19 pandemic in 2020

Introduction

Healthcare providers are at high risk of becoming infected when taking care of patients who have COVID-19, especially while attending aerosol generating procedures. Protective personal equipment must be used in the correct manner to prevent transmission of the disease. Published protocols on protective personal equipment (PPE) donning and doffing have been issued by disease control agencies.

Methods

A questionnaire-based cross-sectional study was designed. An online anonymous questionnaire, which was validated and tested for reliability, focused on PPE related knowledge, donning and doffing practices of healthcare providers across the eastern region of Saudi Arabia.

Results

A total of 312 healthcare providers across the eastern region of Saudi Arabia participated in the study, 208 physicians (66.7%) and 104 non-physicians (33.3%). Results indicate poor practice regarding PPE donning (13.8% reported the correct sequence) and PPE doffing (3.5% reported the correct sequence) among participants. In addition, practice and confidence scores regarding other issues with PPE were analyzed. Based on questionnaire responses, being male (T = 2.825; p = 0.008), being a non-physician (T = -2.120; p = 0.014) and being an allied medical professional (F = 5.379; p = 0.003) were significantly associated with higher confidence levels. Also, being a consultant was significantly associated with higher practice scores (F = 4.774; p = 0.008).

Conclusion

The study demonstrates deficiencies among healthcare providers in following the recommended practices for correctly using PPE during the pandemic. Poor practice in PPE donning and doffing necessitates additional educational and training programs focused on infection control practices.

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.

The effects of chlorination, thickness, and moisture on glove donning efficiency

Changing gloves more frequently is encouraged, more now than ever given the COVID-19 pandemic. When the donning process has moisture introduced, however, complications can arise, which consumes vital time. Most commonly, gloves undergo a chlorination treatment to reduce glove tack, allowing easier donning. To assess the effects of different chlorination strengths and glove thicknesses on donning, acrylonitrile butadiene gloves were manufactured at two different thicknesses (0.05 and 0.10 mm) with 4 different chlorination treatments: 0, 500, 1000 and 2000 ppm. Six participants were used to assess the time taken to don each of the glove sets with dry and wet hands (16 tests in total). Overall, the thicker gloves took longer to don, due to differences in the material stiffness hindering the donning process. The quickest performance from the chlorinated gloves was noted in the 1000 and 2000 ppm concentrations. Wet conditions also showed significant increases in the donning time.Practitioners Summary: The study was conducted based on the gaps identified in previous literature reviews which revealed the requirement for a greater understanding of glove donning process. It was found a stronger chlorination was detrimental when the hands were wet, but better when dry. Thicker gloves were also found to be detrimental.

A novel method to teach and assess the sterility of donning sterile gloves

Sterility is of utmost importance during surgery, particularly orthopaedic surgery. The literature suggests sterility, when compromised, is frequently contaminated at the point of donning sterile gowns and gloves. We describe a novel method to assess the compliance of sterility whilst applying surgical gloves using an ultraviolet lightbox and an ultraviolet-sensitive 'Germ paint'. We carried out an audit of 'sterility' using this method with our surgical trainees. A subsequent educational programme described methods of glove-donning. Repeat assessment yielded significantly improved results. Educating staff using this method may improve sterility in theatre. We believe this is a novel method to teach and assess sterility during glove-donning. The equipment is readily accessible within each NHS hospital. Medical and theatre staff should use this as part of training and departmental induction programmes.
