Automated hand hygiene auditing with and without an intervention

Should automated electronic hand-hygiene monitoring systems be implemented in routine patient care? Systematic review and appraisal with Medical Research Council Framework for Complex Interventions

Manual hand-hygiene audit is time-consuming, labour-intensive and inaccurate. Automated hand-hygiene monitoring systems (AHHMSs) offer advantages (generation of standardized data, avoidance of the Hawthorne effect). World Health Organization Guidelines for Hand Hygiene published in 2009 suggest that AHHMSs are a possible alternative. The objective of this review was to assess the current state of the literature for AHHMSs and offer recommendations for use in real-world settings. This was a systematic literature review, and publications included were from the time that PubMed commenced until 19th November 2023. Forty-three publications met the criteria. Using the Medical Research Council's Framework for Developing and Evaluating Complex Interventions, two were categorized as intervention development studies. Thirty-nine were evaluations. Two described implementation in real-world settings. Most were small scale and short duration. AHHMSs in conjunction with additional intervention (visual or auditory cue, performance feedback) could increase hand hygiene compliance in the short term. Impact on infection rates was difficult to determine. In the few publications where costs and resources were considered, time devoted to improving hand hygiene compliance increased when an AHHMS was in use. Health workers' opinions about AHHMSs were mixed. In conclusion, at present too little is known about the longer-term advantages of AHHMSs to recommend uptake in routine patient care. Until more longer-term accounts of implementation (over 12 months) become available, efforts should be made to improve direct observation of hand hygiene compliance to improve its accuracy and credibility. The Medical Research Council Framework could be used to categorize other complex interventions involving use of technology to prevent infection to help establish readiness for implementation.

The effect of a prospective intervention program with automated monitoring of hand hygiene performance in long-term and acute-care units at a Veterans Affairs medical center

OBJECTIVE

To measure the impact of an automated hand hygiene monitoring system (AHHMS) and an intervention program of complementary strategies on hand hygiene (HH) performance in both acute-care and long-term care (LTC) units.

DESIGN

Prospective, nonrandomized, before-and-after intervention study.

SETTING

Single Veterans Affairs Medical Center (VAMC), with 2 acute-care units and 6 LTC units.

METHODS

An AHHMS that provides group HH performance rates was implemented on 8 units at a VAMC from March 2021 through April 2022. After a 4-week baseline period and 2.5-week washout period, the 52-week intervention period included multiple evidence-based components designed to improve HH compliance. Unit HH performance rates were expressed as the number of dispenses (events) divided by the number of patient room entries and exits (opportunities) × 100. Statistical analysis was performed with a Poisson general additive mixed model.

RESULTS

During the 4-week baseline period, the median HH performance rate was 18.6 (95% CI, 16.5-21.0) for all 8 units. During the intervention period, the median HH rate increased to 21.6 (95% CI, 19.1-24.4; P < .0001), and during the last 4 weeks of the intervention period (exactly 1 year after baseline), the 8 units exhibited a median HH rate of 25.1 (95% CI, 22.2-28.4; P < .0001). The median HH rate increased from 17.5 to 20.0 (P < .0001) in LTC units and from 22.9 to 27.2 (P < .0001) in acute-care units.

CONCLUSIONS

The intervention was associated with increased HH performance rates for all units. The performance of acute-care units was consistently higher than LTC units, which have more visitors and more mobile veterans.

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.

This expert guidance document is sponsored by the Society for Healthcare Epidemiology (SHEA). It is the product of a collaborative effort led by SHEA, the Infectious Diseases Society of America, the Association for Professionals in Infection Control and Epidemiology, the American Hospital Association, and The Joint Commission, with major contributions from representatives of a number of organizations and societies with content expertise.

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.

The impact of automated hand hygiene monitoring with and without complementary improvement strategies on performance rates

Objective:

To determine how engagement of the hospital and/or vendor with performance improvement strategies combined with an automated hand hygiene monitoring system (AHHMS) influence hand hygiene (HH) performance rates.

Design:

Prospective, before-and-after, controlled observational study.

Setting:

The study was conducted in 58 adult and pediatric inpatient units located in 10 hospitals.

Methods:

HH performance rates were estimated using an AHHMS. Rates were expressed as the number of soap and alcohol-based hand rub portions dispensed divided by the number of room entries and exits. Each hospital self-assigned to one of the following intervention groups: AHHMS alone (control group), AHHMS plus clinician-based vendor support (vendor-only group), AHHMS plus hospital-led unit-based initiatives (hospital-only group), or AHHMS plus clinician-based vendor support and hospital-led unit-based initiatives (vendor-plus-hospital group). Each hospital unit produced 1–2 months of baseline HH performance data immediately after AHHMS installation before implementing initiatives.

Results:

Hospital units in the vendor-plus-hospital group had a statistically significant increase of at least 46% in HH performance compared with units in the other 3 groups (P ≤ .006). Units in the hospital only group achieved a 1.3% increase in HH performance compared with units that had AHHMS alone (P = .950). Units with AHHMS plus other initiatives each had a larger change in HH performance rates over their baseline than those in the AHHMS-alone group (P < 0.001).

Conclusions:

AHHMS combined with clinician-based vendor support and hospital-led unit-based initiatives resulted in the greatest improvements in HH performance. These results illustrate the value of a collaborative partnership between the hospital and the AHHMS vendor.

Evaluating automatic hand hygiene monitoring systems: A scoping review

Objectives

To categorize the extant automatic hand hygiene monitoring systems (AHHMSs) and evaluate the capacity of each to provide information on compliance rates.

Study design

Scoping review.

Methods

Three international databases, PubMed, CINAHL, and EBSCO (between 1 January 2010 and 31 December 2020), were searched according to predetermined inclusion criteria for the scoping review. Two authors screened studies for eligibility independently. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR).

Results

Twenty-seven studies were included. Three types of AHHMSs were identified: Type I provides information about the aggregate hand hygiene events (HHEs) only, while Type II adds aggregate hand hygiene opportunities (HHOs), and Type III presents both HHEs and HHOs for individuals. Results suggested that improving the accuracy of recording HHEs and/or HHOs was critical for improving the accuracy of the compliance, which could increase the acceptability of the monitoring system. In addition, the studies found that the implementation of AHHMSs, especially with prompt reminders or additional interventions, could improve the compliance significantly.

Conclusions

The extant AHHMSs could be decomposed into components of 3Ps (product usage monitoring, position monitoring, and performance monitoring). By identifying devices and technology as well as the type of information provided for each component, our approach can aid healthcare facilities to choose a suitable AHHMS that meets their criteria.

A Positive Impact of an Observational Study on Breastfeeding Rates in Two Neonatal Intensive Care Units

We aimed to investigate whether the participation in an observational study on breastfeeding (Doal) modified breastfeeding outcomes in enrolling neonatal intensive care units (NICUs). This bi-centric before-and-after study included neonates who were admitted during a 4-month period before and a 4-month period after the implementation of Doal. Breastfeeding intention and breastfeeding rates at discharge were compared between the two periods. The association between inclusion in Doal and breastfeeding at discharge was assessed among the infants fulfilling the inclusion criteria of Doal. The present study included 655 neonates. After adjustments, both breastfeeding (aOR 1.21, 95%CI [1.1; 1.4], p = 0.001) and exclusive breastfeeding (aOR 1.8, 95%CI [1.4; 2.3], p < 0.001) at discharge increased in the period after. Breastfeeding intention was higher in one center in the period after (79%) compared to before (59%, p = 0.019). Compared to the period before, neonates who were not included in Doal in the period after had a lower chance to be breastfed at discharge, whereas those included were more frequently exclusively breastfed. The participation in an observational study on breastfeeding was associated with an increase in breastfeeding outcomes in enrolling neonatal intensive care units (NICUs). Patients who are not included deserve attention as they are at risk to be disadvantaged regarding breastfeeding success.

Hand Hygiene, an Update

Hand hygiene by health care personnel is an important measure for preventing health care-associated infections, but adherence rates and technique remain suboptimal. Alcohol-based hand rubs are the preferred method of hand hygiene in most clinical scenarios, are more effective and better tolerated than handwashing, and their use has facilitated improved adherence rates. Obtaining accurate estimates of hand hygiene adherence rates using direct observations of personnel is challenging. Combining automated hand hygiene monitoring systems with direct observations is a promising strategy, and is likely to yield the best estimates of adherence. Greater attention to hand hygiene technique is needed.

Information technology on hand hygiene compliance among health care professionals: A systematic review and meta-analysis

AIM

To determine the effectiveness of information technology interventions on hand hygiene compliance among health care professionals.

BACKGROUND

Performing hand hygiene is the optimal approach to prevent the transmission of health care-associated infections. However, results regarding the effectiveness of information technology interventions on hand hygiene compliance were inconsistent to date.

EVALUATION

A search for studies published up to May 2020 was undertaken. A meta-analysis was conducted using RevMan 5.3 software.

KEY ISSUES

The most commonly used information technology systems were as follows: automated training, electronic counting devices and remote monitoring, real-time hand hygiene reminders and feedback, and automated monitoring. These four types of technology systems can significantly improve hand hygiene compliance among health care professionals (odds ratio = 3.06, p < .001).

CONCLUSION

The four types of information technology can be effectively used to change the hand hygiene behaviour. Because the information systems can monitor personnel and conduct statistical analyses automatically, they save labour costs of human monitors, are more time efficient and eliminate accompanying human error.

IMPLICATIONS FOR NURSING MANAGEMENT

The use of the four types of information technology is convenient and could reduce health care-associated infections; thus, they could be widely used in the future as the key to increase hand hygiene compliance rate.

Impact of an automated hand hygiene monitoring system combined with a performance improvement intervention on hospital-acquired infections

OBJECTIVE

Hand hygiene adherence has been associated with reductions in nosocomial infection. We assessed the effect of improvements in electronically measured hand hygiene adherence on the incidence of hospital-acquired infections.

METHODS

This quasi-experimental study was conducted in a 555-bed urban safety-net level I trauma center. The preintervention period was January 2015 through June 2016. Baseline electronic hand hygiene data collection took place from April through June 2016. The intervention period was July 2016 through December 2017. An electronic hand hygiene system was installed in 4 locations in our hospital. Performance improvement strategies were implemented that included education, troubleshooting, data dissemination, and feedback. Adherence rates were tracked over time. Rates of hospital-acquired infections were evaluated in the intervention units and in control units selected for comparison. The intervention period was subdivided into the initial and subsequent 9-month periods and were compared to the baseline period.

RESULTS

Electronically measured hand hygiene rates improved significantly from baseline to intervention, from 47% 77% adherence. Rates >70% continued to be measured 18 months after the intervention. Interrupted time series analysis indicated a significant effect of hand hygiene on healthcare facility-onset Clostridioides difficile infection rates during the first 9 months of the intervention. This trend continued during the final 9 months of the intervention but was nonsignificant. No effects were observed for other hospital-acquired infection rates.

CONCLUSIONS

Implementation of electronic hand hygiene monitoring and performance improvement interventions resulted in reductions in hospital-onset Clostridioides difficile infection rates.

The impact of automatic video auditing with real-time feedback on the quality and quantity of handwash events in a hospital setting

BACKGROUND

Poor quality handwashing contributes to the spread of nosocomial infections. We investigate the impact of automatic video auditing (AVA) with feedback on the quality and quantity of handwashing in a hospital setting.

METHODS

AVA systems were mounted over all handwash sinks in a surgical unit. Phase 1 established baseline handwashing quality and quantity. Phase 2 examined the impact of real-time performance feedback, and phase 3 examined the incremental impact of weekly team performance reports. Phase 4 remeasured the baseline without feedback.

RESULTS

A total of 3,606 handwash events were audited. During phase 2 and 3, compliance with the World Health Organization technique improved from 15.7%-46% (P < .0001), and the average number of handwash events per patient per day increased from 0.91-2.25 (P < .0001). Performance returned to baseline in phase 4.

CONCLUSIONS

AVA with real-time feedback significantly improved the quality and quantity of handwashing. The combination of AVA with electronic monitoring will allow simultaneous auditing of hand hygiene quantity and quality. The impact of cognitive offloading onto the technology may have contributed to the return to baseline at the end of the study, and suggests further research is required in this area.

Hand hygiene compliance monitoring: Do video-based technologies offer opportunities for the future?

Hand hygiene is universally recognised as the primary measure to reduce healthcare-associated infections. Studies have convincingly demonstrated a link between increased hand hygiene compliance and reductions in rates of healthcare-associated infections. Direct observation is considered the gold standard method for monitoring hand hygiene compliance. Despite the acknowledged benefits of this approach, recent literature has highlighted a range of issues impacting on the reliability and validity of this data collection technique. The rise of technology in healthcare provides opportunity for alternative methods that promise advantages over direct human observation. There have been no published examples of systems that are able to capture data consistent with all the WHO '5 Moments for Hand Hygiene'. In this paper we explore current human-based auditing practises for monitoring hand hygiene compliance and raise for discussion and debate video-based technologies to monitor hand hygiene compliance. We raise questions regarding hybrid approaches that incorporate both direct human observation and indirect video-based surveillance, and the possible advantages and disadvantages therein for monitoring hand hygiene compliance. We suggest that such methods have the potential to ameliorate, or minimise, the inherent biases associated with direct observation, notably the Hawthorne Effect. Future research into the utility of a hybrid approach to auditing, including the technical specifications, efficacy, cost effectiveness and acceptability of such a model is warranted.

Challenges encountered and lessons learned during a trial of an electronic hand hygiene monitoring system

BACKGROUND

Automated hand hygiene monitoring systems (AHHMS) are being developed to supplement direct observations of hand hygiene (HH). We compared compliance rates generated by direct observations and by a badge-based AHHMS.

METHODS

Observations of HH compliance were conducted in a surgical intensive care unit (SICU) and a general medical ward (GMW) during a 7-month baseline period and a 13-week intervention period, when compliance was also estimated using an AHHMS. Compliance rates were analyzed using time-series analysis.

RESULTS

During the entire pre- and postintervention period, univariate analysis of observations revealed significant improvement in overall HH compliance in the SICU (P = .001) and the GMW (P = .03), beginning before implementation of the AHHMS. Initiation of the AHHMS was associated with a transient drop in entry and exit compliance on both units. During the intervention period, observations suggested that compliance on entry and exit continued to increase in the SICU, but not in the GMW. Time series analysis of AHHMS data revealed that entry and exit compliance did not change significantly in the SICU but decreased significantly in the GMW (P = .001). The average accuracy of the AHHMS was 60%.

CONCLUSIONS

Based on observations, HH compliance increased during the baseline period. Observations and the AHHMS yielded different trends in compliance. The AHHMS's accuracy of HH events and health care personnel location were suboptimal.

An in-room observation study of hand hygiene and contact precaution compliance for Clostridioides difficile patients

Using an innovative, covert, in-room observer method to evaluate infection control practices for patients with Clostridioides difficile infection, we found no difference between physician and nursing hand hygiene compliance and contact precaution usage. There was also no diurnal variation in hand hygiene practices, but decreased contact precaution usage at night. Conversely, hospital-wide data from overt observations collected over the same time period showed significantly higher hand hygiene compliance among nurses than physicians.

Modified glove use for contact precautions: Health care workers' perceptions and acceptance

BACKGROUND

Patients colonized or infected with methicillin-resistant Staphylococcus aureus and or vancomycin-resistant Enterococcus are placed under contact precautions. Contact precautions require patients to be placed in single rooms and their health care workers (HCWs) to wear gowns, aprons and gloves on entry and doffing on exit. Glove use is widely accepted to be associated with poor hand hygiene compliance. We trailed the removal of gloves for contact precautions for contacts not expected to involve body fluids to improve hand hygiene between multiple contacts of the patient and patient zone.

METHODS

We have conducted a 5 phase study of the removal of gloves for contacts without body fluids in 250 HCWs using pretrial focus groups (N = 12), hand microbiology (N = 40) (reported elsewhere), development of a modified contact precautions poster, trial of modified poster (n = 100), posttrial focus group discussion (n = 22), and a survey of HCWs postrollout in additional locations (n = 76).

RESULTS

Pretrial focus groups identified 4 themes, and the leading theme identified as the facilitator for glove use as self-protection. HCWs viewed current contact precaution guidelines as preventing them from making their own judgement regarding the need for gloving for patient contacts, leading continuous glove use without changing gloves between multiple contacts. Participants believed that the trial empowered them to make their own clinical judgment for gloves and to consciously use hand hygiene between dry (no body fluid) contacts. Four themes were discussed during the posttrial focus groups and although self-protection remained the central theme, hand hygiene replaced glove use. Participants spoke of an appreciation of and increased trust in hand hygiene during nonglove use for dry contacts. The survey responses from additional sites were mostly positive for the safety of nonglove use for dry contacts, it improved hand hygiene and that the adoption of the modified guidelines was empowering.

CONCLUSIONS

The trial of nonglove use for expected dry contact, while caring for patients under contact precautions for methicillin-resistant S aureus and or vancomycin-resistant Enterococcus, was successful in refocusing HCWs reliance on hand hygiene for self-protection. Mandatory glove use for contact precautions was believed to contribute to their failure to change gloves between procedures on the same patient and patient zone, with HCWs now recognizing multiple contacts with the same gloves as a risk for contamination.

Current issues in hand hygiene

Although substantial improvements in hand hygiene practices have occurred in recent years, many health care facilities continue to encounter challenges in achieving and maintaining high levels of hand hygiene compliance. Issues of current interest include the optimum dose of alcohol-based handrub (ABHR) that should be applied, the impact of hand size and alcohol-based handrub dry times have on efficacy, and ideal hand hygiene technique. There is a need to determine which additional promotional activities can augment improvements in hand hygiene that are achieved by implementing the multimodal improvement strategy recommended by the World Health Organization. Monitoring hand hygiene performance and providing personnel with feedback on their performance are essential elements of successful improvement programs. Further research is needed to establish the most effective methods of providing feedback. Additional studies are needed to optimize strategies for performing direct observation of hand hygiene compliance, and to determine the role of supplementing direct observations using automated monitoring systems.

Impact of an automated hand hygiene monitoring system and additional promotional activities on hand hygiene performance rates and healthcare-associated infections

OBJECTIVE

Determine the impact of an automated hand hygiene monitoring system (AHHMS) plus complementary strategies on hand hygiene performance rates and healthcare-associated infections (HAIs).

DESIGN

Retrospective, nonrandomized, observational, quasi-experimental study.

SETTING

Single, 93-bed nonprofit hospital.

METHODS

Hand hygiene compliance rates were estimated using direct observations. An AHHMS, installed on 4 nursing units in a sequential manner, determined hand hygiene performance rates, expressed as the number of hand hygiene events performed upon entering and exiting patient rooms divided by the number of room entries and exits. Additional strategies implemented to improve hand hygiene included goal setting, hospital leadership support, feeding AHHMS data back to healthcare personnel, and use of Toyota Kata performance improvement methods. HAIs were defined using National Healthcare Safety Network criteria.

RESULTS

Hand hygiene compliance rates generated by direct observation were substantially higher than performance rates generated by the AHHMS. Installation of the AHHMS without supplementary activities did not yield sustained improvement in hand hygiene performance rates. Implementing several supplementary strategies resulted in a statistically significant 85% increase in hand hygiene performance rates (P &lt; .0001). The incidence density of non-Clostridioies difficile HAIs decreased by 56% (P = .0841), while C. difficile infections increased by 60% (P = .0533) driven by 2 of the 4 study units.

CONCLUSION

Implementation of an AHHMS, when combined with several supplementary strategies as part of a multimodal program, resulted in significantly improved hand hygiene performance rates. Reductions in non-C. difficile HAIs occurred but were not statistically significant.

Improving hand hygiene compliance with patient zone demarcation: More than just lines on the floor

Background

Hand hygiene compliance can be difficult to improve as this prospective activity may not come to mind easily during busy clinical operations. Clinicians are often driven by clinical goals under time pressure, and the sudden recall to clean hands can either be disruptive or too late. Using patient zones as a reference has been known to be helpful. A low-tech solution of taping patient zones on the floor was introduced in a children’s intensive care unit. Coupled with this demarcation is a simplified protocol that uses patient zones for “just-in-time” reminders. Clinicians now clean their hands whenever they cross zone lines, namely “ before patient zone” and “ after patient zone”, along with “ before aseptic procedure” and “ after bodily fluids exposure”.

Methods

The mandatory national quarterly hand hygiene surveillance data for children’s intensive care unit and the entire hospital was tracked. Seven pre-intervention and seven post-intervention quarters were compared for improvement and sustainability.

Results

Overall, children’s intensive care unit hand hygiene compliance rose from an average of 77% to 90%, as well as physicians' hand hygiene compliance rates from 72% to 86%, and these differences are statistically significant. Hand Hygiene Moment 1 as defined by World Health Organization benefited the most from this intervention.

Discussion

Patient zone demarcation, along with more intuitive hand hygiene guidelines, is a cost-effective, operationally sensitive intervention that can improve hand hygiene compliance. The bundled solution taps on human factors science in understanding the cognitive challenges faced by clinicians. The positive effects are most profound in multi-bed cubicles where patient zones and infection control barriers are not clearly visible.

Transmission of Staphylococcus aureus from dry surface biofilm (DSB) via different types of gloves

Background

Pathogens can survive for extended periods when incorporated into biofilm on dry hospital surfaces (ie, dry-surface biofilm, DSB). Bacteria within biofilm are protected from desiccation and have increased tolerance to cleaning agents and disinfectants.

Objective

We hypothesized that gloved hands of healthcare personnel (HCP) become contaminated with DSB bacteria and hence may transmit bacteria associated with healthcare-associated infections (HAIs).

Method

Staphylococcus aureus DSB was grown in vitro on coupons in a bioreactor over 12 days with periodic nutrition interspersed with long periods of dehydration. Each coupon had ~107 DSB bacterial cells. Transmission was tested with nitrile, latex, and surgical gloves by gripping DSB-covered coupons then pressing finger tips onto a sterile horse blood agar surface for up to 19 consecutive touches and counting the number of colony-forming units (CFU) transferred. Coupons were immersed in 5% neutral detergent to simulate cleaning, and the experiment was repeated.

Results

Bacterial cells were readily transmitted by all 3 types of gloves commonly used by HCP. Surprisingly, sufficient S. aureus to cause infection were transferred from 1 DSB touch up to 19 consecutive touches. Also, 6 times more bacteria were transferred by nitrile and surgical gloves than to latex gloves (P <.001). Treating the DSB with 5% neutral detergent increased the transmission rate of DSB bacteria 10-fold.

Conclusion

Staphylococcus aureus incorporated into environmental DSB and covered by extracellular polymeric substances readily contaminates gloved hands and can be transferred to another surface. These results confirm the possibility that DSB contributes to HAI acquisition.

Hand hygiene compliance rates: Fact or fiction?

BACKGROUND

The mandatory national hand hygiene program requires Australian public hospitals to use direct human auditing to establish compliance rates. To establish the magnitude of the Hawthorne effect, we compared direct human audit rates with concurrent automated surveillance rates.

METHODS

A large tertiary Australian teaching hospital previously trialed automated surveillance while simultaneously performing mandatory human audits for 20 minutes daily on a medical and a surgical ward. Subtracting automated surveillance rates from human audit rates provided differences in percentage points (PPs) for each of the 3 quarterly reporting periods for 2014 and 2015.

RESULTS

Direct human audit rates for the medical ward were inflated by an average of 55 PPs in 2014 and 64 PPs in 2015, 2.8-3.1 times higher than automated surveillance rates. The rates for the surgical ward were inflated by an average of 32 PPs in 2014 and 31 PPs in 2015, 1.6 times higher than automated surveillance rates. Over the 6 mandatory reporting quarters, human audits collected an average of 255 opportunities, whereas automation collected 578 times more data, averaging 147,308 opportunities per quarter. The magnitude of the Hawthorne effect on direct human auditing was not trivial and produced highly inflated compliance rates.

CONCLUSIONS

Mandatory compliance necessitates accuracy that only automated surveillance can achieve, whereas daily hand hygiene ambassadors or reminder technology could harness clinicians' ability to hyperrespond to produce habitual compliance.

An Initiative to Reduce the Episiotomy Rate: Association of Feedback and the Hawthorne Effect With Leapfrog Goals

OBJECTIVE

To assess the association of education, performance feedback, and the Hawthorne effect with a reduction in the episiotomy rate in a large academic institution.

METHODS

We describe a prospective observational study of a project conducted between March 2012 and February 2017 to assist clinicians in meeting the Leapfrog Group (www.leapfroggroup.org) target rates for episiotomy. Phases of this project included preintervention (phase 1, March 2012 to April 2014), education and provision of collective department episiotomy rates (phase 2, May 2014 to December 2014), ongoing education with emphasis on a revised Leapfrog target rate (phase 3, January 2015 to February 2016), and provision of individual episiotomy rates to practitioners on a monthly basis (phase 4, March 2016 to February 2017). We analyzed the department episiotomy rates before, during, and after these efforts. Cases of shoulder dystocia were excluded from this analysis. Statistical analysis was performed using a two-tailed Student t test and χ test with P<.05 considered significant.

RESULTS

During the study period 1,176 episiotomies were performed in 16,441 vaginal deliveries (7.2%). In phase 2 (2,352 vaginal deliveries), there was a nonsignificant drop in the episiotomy rate with education alone (9.0-8.2%, P=.21). In phase 3 (4,379 vaginal deliveries), the episiotomy rate demonstrated an additional, significant drop to 5.9% (P<.001), but this reduction did not reach the new Leapfrog goal of 5%. In phase 4 (3,160 vaginal deliveries), the hospital episiotomy rate again dropped significantly from 5.9% to 4.37% (P=.007) and met the target rate of 5%. This reduction was sustained over a 12-month time period. During this same time period, the rate of operative vaginal delivery among vaginal births increased (4.5-5.4%, P=.003) and there was no significant change in the rates of third- and fourth-degree perineal laceration (3.8-3.3%, P=.19).

CONCLUSION

Education, performance feedback, and the Hawthorne effect were associated with a reduction in the episiotomy rate in a large academic institution without a reduction in the rate of operative vaginal delivery or an increase in the rate of third- and fourth-degree lacerations.

An automated hand hygiene compliance system is associated with improved monitoring of hand hygiene

BACKGROUND

Consistent hand hygiene is key to reducing health care-associated infections (HAIs) and assessing compliance with hand hygiene protocols is vital for hospital infection control staff. A new automated hand hygiene compliance system (HHCS) was trialed as an alternative to human observers in an intensive care unit and an intensive care stepdown unit at a hospital facility in the northeastern United States.

METHODS

Using a retrospective cohort design, researchers investigated whether implementation of the HHCS resulted in improved hand hygiene compliance and a reduction in common HAI rates. Pearson χ² tests were used to assess changes in compliance, and incidence rate ratios were used to test for significant differences in infection rates.

RESULTS

During the study period, the HHCS collected many more hand hygiene events compared with human observers (632,404 vs 480) and ensured that the hospital met its compliance goals (95%+). Although decreases in multidrug-resistant organisms, central line-associated bloodstream infections, and catheter-associated urinary tract infection rates were observed, they represented nonsignificant differences.

DISCUSSION AND CONCLUSIONS

Human hand hygiene observers may not report accurate measures of compliance. The HHCS is a promising new tool for fine-grained assessment of hand hygiene compliance. Further study is needed to examine the association between the HHCS and HAI rate reduction.

Social cohesion: The missing factor required for a successful hand hygiene program

BACKGROUND

There are limited explorations into hospital staff reactions to automated hand hygiene surveillance or hand hygiene interventions.

METHODS

An automated surveillance system with daily feedback and a behavioral intervention component was trialed in 2 wards in an Australian tertiary teaching hospital. After 9 months, 12 clinicians from each ward were interviewed prior to the completion of the trial to explore satisfaction with the system and behavioral component of nudging each other with a reminder to comply. Only on completion of the trial were transcripts analyzed for themes.

RESULTS

Staff from the ward with improved compliance described a socially cohesive team with a well-liked nurse unit manager who accessed daily compliance rates and worked with staff to set goals. This contrasted with the ward without improvement in compliance, whose staff described their great reluctance and discomfort to nudge each other to comply and distrust of the authenticity of the rates established from the automated system.

CONCLUSIONS

Interventions for improving compliance are more likely to be successful in a ward with a social cohesive team. Patient safety interventions, in the first instance, may benefit from purposeful selection of wards with cohesive teams and skilled leaders who can transform clinicians into early adopters of the program.
