Methodological and technical considerations for video-based auditing of hand hygiene compliance in clinical practice: an exploratory study

Impacts of intelligent monitoring technology installation and additional modalities on hand hygiene compliance in a burn center: A quasi-experimental longitudinal trial

BACKGROUND

The increasing development of intelligent technologies for hand hygiene (HH) compliance audit has the potential to create an alternative to direct observation (DO), which is still considered the gold standard but has disadvantages such as lack of standardized monitoring practices, Hawthorne effect, insufficient sample size, and time/resource consumption. We aimed to share our preliminary results on the impacts of intelligent monitoring technology installation (IMTI) and additional modalities on healthcare workers' (HCWs') HH compliance in a Burn Center, according to the "5 Moments of HH" concept defined by the World Health Organization (WHO).

METHODS

A quasi-experimental longitudinal trial was conducted over eleven months.The first phase of the three-stage study evaluated basic HH compliances obtained by DO. The system-defined HH performances, which IMTI recorded, were assessed in the second phase. Finally, the effect of IMTI and additional modalities was determined in the third stage.

RESULTS

15202 HH events were performed by 41 HCWs, and a total of 20095 HH opportunities were observed. Four hundred fifty-five opportunities were in the preinstallation phase, and 19640 were during the total post-installation period. IMTIdefined performance rates in both Phase 2 (71.2%) and Phase 3 (80.5%) were generally considerably higher than HH compliances obtained from DO (58.5%). Nurses, physical therapy /anesthesia technicians, and housekeeping personnel showed significant increases, which was insignificant in physicians in phase 2. Meanwhile, a sustained increase was observed regarding IMTI and additional modalities of HH compliance of all HCWs in Phase 3.

CONCLUSION

IMTI has significantly increased HH performance rates. Furthermore, combining the IMTI with additional modalities as components of a multimodal strategy recommended by WHO appears to affect the sustainability of the increasing trend of HCWs' HH compliance.

Current issues in hand hygiene

BACKGROUND

Multiple aspects of hand hygiene have changed in recent years.

METHODS

A PubMed search was conducted to identify recent articles about hand hygiene.

RESULTS

The COVID-19 pandemic caused temporary changes in hand hygiene compliance rates and shortages of alcohol-based hand sanitizers (ABHSs), and in marketing of some products that were ineffective or unsafe. Fortunately, ABHSs are effective against SARS-CoV-2 and other emerging pathogens including Candida auris and mpox. Proper placement, maintenance, and design of ABHS dispensers have gained additional attention. Current evidence suggests that if an adequate volume of ABHS has been applied to hands, personnel must rub their hands together for at least 15 seconds before hands feel dry (dry time), which is the primary driver of antimicrobial efficacy. Accordingly, practical methods of monitoring hand hygiene technique are needed. Direct observation of hand hygiene compliance remains a challenge in many healthcare facilities, generating increased interest in automated hand hygiene monitoring systems (AHHMSs). However, several barriers have hindered widespread adoption of AHHMSs. AHHMSs must be implemented as part of a multimodal improvement program to successfully improve hand hygiene performance rates.

CONCLUSIONS

Remaining gaps in our understanding of hand hygiene warrant continued research into factors impacting hand hygiene practices.

Health care workers' experiences of video-based monitoring of hand hygiene behaviors: a qualitative study

BACKGROUND

Hand hygiene is key to preventing health care-associated infections. Human observation is the gold standard for measuring compliance, but its utility is increasingly being questioned with calls for the use of video monitoring approaches. The utility of video-based systems to measure compliance according to the WHO 5 moments is largely unexamined, as is its acceptability amongst health care workers (HCW) and patients. This study examined HCW acceptability of video monitoring for hand hygiene auditing.

METHODS

Following trial of a video monitoring system (reported elsewhere), 5 participating HCW attended 2 in-depth group interviews where they reviewed the footage and explored responses to the approach. Transcripts were analyzed using thematic analysis.

RESULTS

Four themes were identified: 1) Fears; 2) Concerns for patients; 3) Changes to feedback; and 4) Behavioral responses to the cameras. HCWs expressed fears of punitive consequences, data security, and confidentiality. For patients, HCWs raised issues regarding invasion of privacy, ethics, and consent. HCWs suggested that video systems may result in less immediate feedback but also identified potential to use the footage for feedback. They also suggested that the Hawthorne Effect was less potent with video systems than human observation.

CONCLUSIONS

The acceptability of video monitoring systems for hand hygiene compliance is complex and has the potential to complicate practical implementation. Additionally, exploration of the acceptability to patients is warranted.

Using video-based surveillance for monitoring hand hygiene compliance according to the World Health Organization (WHO) Five Moments framework: A pragmatic trial

Objective:

To examine the utility of video-based monitoring systems (VMSs) for auditing hand hygiene compliance according to the World Health Organization (WHO) Five Moments.

Design:

Pragmatic quasi-experimental observation trial.

Setting:

The New South Wales Biocontainment Centre, Westmead, New South Wales, Australia.

Participants:

Volunteer healthcare workers (HCWs).

Method:

Six high-fidelity simulations were recorded and subsequently assessed for their ability to audit hand hygiene compliance according to the WHO Five Moments for hand hygiene criteria using tools provided by the National Hand Hygiene Initiative (NHHI).

Results:

In total, 206 minutes of recorded footage were reviewed in 120 minutes, yielding 111 moments. Overall HCW hand hygiene compliance was 88% according to the WHO Five Moments framework. The cost per moment was $0.91 AUD ($0.66 USD) and the time required per moment was 64 seconds.

Conclusions:

Auditing of hand hygiene compliance according to all 5 of the WHO Five Moments from recorded footage is not only possible but provides cost and time savings. In addition, the process may produce output that is less subject to the biases inherent in direct human observational auditing.

Rapid development and implementation of a behaviour change strategy to improve COVID-19 personal protective equipment use in a regional Australian emergency department

Objective

To identify barriers to, describe the development of and evaluate the implementation of a behavioural theory informed strategy to improve staff personal protective equipment (PPE) compliance during COVID-19 in a regional Australian Emergency Department.

Methods

Barriers to PPE use were identified through staff consultation then categorised using the Theoretical Domains Framework. The Behaviour Change Wheel was used to develop a strategy to address the barriers to PPE compliance. The strategy was refined and endorsed by the site COVID taskforce. Data were collected through direct observation. Descriptive statistics were used to summarise PPE compliance and inductive content analysis for free text data of staff behaviours.

Results

73 barriers were identified, mapped to 9 intervention functions and 42 behaviour change techniques. The predominant mechanisms were: (1) Executive communication reinforcing policy and consequences; (2) implementation of a PPE Marshal; (3) face to face reinforcement / modeling; (4) environmental restructuring including electronic medical record modifications. The PPE Marshal observed 281 PPE activities. PPE compliance varied between 47.9% (Buddy check) and 91.8% (Bare below elbow). The PPE Marshal intervened on 121 occasions, predominantly through buddying, explaining and demonstrating correct PPE use, most frequently with medical staff (72%).

Conclusion

We describe an evidence-based process to overcome barriers to PPE compliance that maximize safe work practice in a time critical situation. Staff require enabling, access to equipment and reinforcement to use PPE correctly.
