Current hand hygiene education is suboptimal

Determinants of compliance with infection prevention measures by physicians: a scoping review

Despite evidence that application of infection prevention measures can reduce healthcare-associated infections, compliance with these measures is low, especially among physicians. Intervention effects often do not sustain. An overview of determinants for physicians' infection prevention behaviour and successful behaviour change strategies is lacking. The aim of this review was to identify what determinants influence physicians' infection prevention behaviour, what strategies to improve compliance have been explored, and whether theories, models, and frameworks from implementation science have been used in these studies. A literature search was performed in PubMed, Embase, APA PsycInfo and Web of Science up to June 2nd, 2023, in collaboration with a medical information specialist. All study types focusing on infection prevention behaviour of physicians in high-income countries were included. Data on determinants and strategies was extracted; determinants were categorized into the Theoretical Domains Framework (TDF). Fifty-six articles were included. The TDF domains 'environmental context and resources', 'social influences', 'beliefs about consequences', 'memory, attention and decision-making', 'knowledge', and 'skills' were found most relevant. The prevailing determinant covers a theme outside the TDF: socio-demographic factors. Sustainable interventions are multimodal approaches that at least include feedback, education, and a champion. Theories, models, and frameworks have rarely been used to guide implementation strategy development. In conclusion, it was found that intervention studies rarely specify the determinants that they aim to address and they lack theoretical underpinning. Future initiatives should combine knowledge about determinants with implementation science to develop theory-based interventions tailored to determinants.

Reducing Carbapenem-Resistant Enterobacteriaceae Using the Targeted Solution Tool: A Quality Improvement Project

BACKGROUND

Carbapenem-resistant Enterobacteriaceae (CRE) is a worldwide urgent health problem. Hand hygiene (HH) is an effective intervention to reduce the spread of CRE.

LOCAL PROBLEM

In 2017, an increase in the rate of health care-associated (HA) CRE colonization was observed in a large multiorgan transplant center in Italy. This study aimed to reduce the HA-CRE colonization rates by improving HH compliance.

METHODS

A pre-/post-intervention project was conducted from November 2017 through December 2020.

INTERVENTIONS

The DMAIC (Define, Measure, Analyze, Improve, and Control) framework was used to implement the HH Targeted Solution Tool (TST).

RESULTS

Hand hygiene compliance increased from 49% to 76.9% after the Improve phase ( P = .0001), and to 81.9% after the second Control phase ( P = .0001). The rate of HA-CRE decreased from 24.9% to 5.6% ( P = .0001).

CONCLUSIONS

Using the DMAIC framework to implement the TST can result in significant improvements in HH compliance and HA-CRE colonization rates.

The impacts of self-expectation leadership and organizational commitment on hand hygiene behavior of medical staff based on the theory of implicit leadership

Hand hygiene behavior (HHB) in healthcare settings remains suboptimal globally. Self-expectation leadership and organizational commitment are emphasized as important factors influencing HHB. However, there are no studies to support any relationship between self-expectation leadership and organizational commitment to HHB. This study will fill the gap by applying implicit leadership theory (ILT) to support the further promote HHB among medical staff. A cross-sectional study of 23,426 medical staff was conducted in all second-level and third-level hospitals in Hubei province, China. Based on ILT, an online self-administered and anonymous questionnaire was designed for measuring the medical staff’s self-expectation leadership, organizational commitment, and HHB based on Offermann’s 8 dimensions scale, Chang’s 3 dimensions scale, and the specification of hand hygiene for healthcare workers, respectively, in which self-expectation leadership was divided into positive traits and negative traits parts. The structural equation model was used to examine the direct, indirect, and mediating effects of the variables. Positive traits of self-expectation leadership had a positive effect on organizational commitment (β = 0.617, p < 0.001) and HHB (β = 0.180, p < 0.001). Negative traits of self-expectation leadership had a negative effect on organizational commitment (β = –0.032, p < 0.001), while a positive effect on HHB (β = 0.048, p < 0.001). The organizational commitment had a positive effect on HHB (β = 0.419, p < 0.001). The mediating effect of the organizational commitment showed positively between positive traits of self-expectation leadership and HHB (β = 0.259, p < 0.001), while negatively between negative traits of self-expectation leadership and HHB (β = –0.013, p < 0.001). Positive traits of self-expectation leadership are important predictors of promoting organizational commitment and HHB, while negative traits of self-expectation leadership have a limited impact on organizational commitment and HHB in the field of healthcare-associated infection prevention and control. These findings suggest the need to focus on positive traits of self-expectation leadership; although negative traits of self-expectation leadership can also promote HHB to a lesser degree among medical staff, it will reduce their organizational commitment.

A survey of hand hygiene practices among Indian medical undergraduates

Background

Hand hygiene is the simplest and most effective method to prevent hospital acquired infections (HAI). Compliance with hand hygiene among health providers is, however, widely variable due to significant knowledge gaps and behavioral issues. The knowledge and practices of hand hygiene among medical undergraduate students, the future health workforce in the current COVID-19 pandemic will enable a reality check and ensure course correction at an early stage of their learning.

Methods

An online questionnaire-based survey based on a standard, validated WHO 25-point (multiple-choice question and Yes/No answers) hand hygiene survey was undertaken among medical undergraduate students in an urban city from April to June 2020. Each correct response was awarded 1 point, and an incorrect response was awarded 0 points. The maximum achievable score was 25, and the minimum score was 0.

Results

A total of 457 students with a mean age 20.24 ± 1.27 years completed the survey. A total of 415 (90.8%) students received hand hygiene training in the past three years. Overall 27.6% (n = 126) students had good knowledge, 65.4% (n = 299) had moderate and 7% (n = 32) had poor knowledge of hand hygiene practices.

Conclusions

There were significant knowledge gaps regarding hand hygiene among medical undergraduate students in the midst of the COVID-19 pandemic. There is a need to strengthen existing teaching methods to positively impact behavioral change and potentially translate into better hand hygiene compliance among the future health workforce of the country.

Supporting the Delivery of Infection Prevention and Control Training to Healthcare Workers: Insights from the Sector

Infection prevention and control (IPC) cannot be implemented without healthcare workers (HCWs) being properly trained and competent. The provision of training is essential, yet there is a gap in our understanding of the factors impacting the implementation of IPC training. This paper reports the results from in-depth interviews that explored the current landscape around IPC training delivered across low-, middle-, and high-income countries. Semi-structured interviews were conducted with the key stakeholders involved in policymaking or IPC implementation in Saudi Arabia, Pakistan, India, Indonesia, the Philippines, and Australia. Although the training was mandated for many HCWs, participants indicated that only some training elements were mandatory. Participants spoke about covering various topics, but those in low-resource settings spoke about the challenges of delivering training. Classroom-based training dominated, but online delivery modes were also used in some locations. Whilst HCW’s training was postulated to have improved during the COVID-19 pandemic, the capacity to deliver training did not improve in some settings. More research is needed to establish the essential elements that could underpin the development of training packages.

Tactile disgust: Post-contact can be more disgusting than contact

Several studies have examined if disgust can be evoked by contacting an object-yet none have examined if reported disgust changes when the hand leaves the object. This is surprising given that post-contact tactile disgust is probably a driver of hand hygiene. We examined contact and post-contact tactile disgust and its sensory origins. Participants were asked to touch several objects, making sensory, disgust, and desire-to-handwash evaluations. These ratings were made at three stages-of-contact: object-contact (just touch), post-contact (just touch), and visual post-contact (touch, vision). Disgust was typically highest at post-contact (when the hand left the object). Stickiness and wetness were uniquely predictive of object-contact disgust. Only stickiness drove post-contact disgust, and only wetness visual post-contact disgust. Hand-washing desire was primarily driven by quantity of residue perceived on the hand. These findings suggest that tactile disgust is a multisensory and iterative process relating to object- and residue-adhesiveness.

Deterioration in hygiene behavior among fifth-year medical students during the placement of intravenous catheters: a prospective cohort comparison of practical skills

BACKGROUND

The American Association of Medical Colleges has defined peripheral intravenous cannulation as one of the eight practical skills that a medical student should possess upon graduation. Since following a standard hygiene protocol can reduce the rate of complications such as bloodstream infections, the medical student's compliance to hygienic standards is highly relevant.

METHODS

This unicentric longitudinal cohort study included 177 medical students undergoing OSCE 1 in the winter semesters 2016/2017 and 2017/2018 as well as OSCE 2 during the winter semesters 2018/2019 and 2019/2020 at the University of Cologne. Their performance in peripheral intravenous cannulation was rated by trained student supervisors using a scaled 13-item questionnaire and compared between OSCE 1 and OSCE 2.

RESULTS

Overall, a decline in the correct placement of peripheral intravenous catheters was observed among advanced medical students during OSCE 2 (mean total score: 6.27 ± 1.84) in comparison to their results in OSCE 1 (mean total score: 7.67 ± 1.7). During OSCE 2, the students were more negligent in regard to hygienic behavior, such as disinfection of the puncture site as well as hand disinfection before and after venipuncture. Their patients were also less likely to be informed about the procedure as compared to OSCE 1.

CONCLUSIONS

An unsatisfying performance in regard to peripheral intravenous cannulation was observed in medical students with hygiene compliance deteriorating between the third and fifth year of their study. Thus, we promote an extension of practical hygiene and stress management training in medical school to reduce complications associated with intravenous catheters, such as bloodstream infections.
