The objective of this study was to evaluate the efficacy of dirt removal (bacteria and organic matter) of several hand-cleaning procedures. The results from the hand hygiene experiment indicated that washing hands with warm water and soap for 20 s is the most effective method investigated when hands are either dirty or greasy. Even if not proper washing, rinsing under running water for 5 s is a cleaning procedure that may significantly reduce the probability of cross-contamination, as it removes ...[more]

Project description:ObjectiveThe study sought to identify smartphone apps that support hand hygiene practice and to assess their content, technical and functional features, and quality. A secondary objective was to make design and research recommendations for future apps.Materials and methodsWe searched the UK Google Play and Apple App stores for hand hygiene smartphone apps aimed at adults. Information regarding content, technical and functional features was extracted and summarized. Two raters evaluated each app, using the IMS Institute for Healthcare Informatics functionality score and the Mobile App Rating Scale (MARS).ResultsA total of 668 apps were identified, with 90 meeting the inclusion criteria. Most (96%) were free to download. The majority (78%) intended to educate or inform or remind users to hand wash (69%), using behavior change techniques such as personalization and prompting practice. Only 20% and 4% named a best practice guideline or had expert involvement in development, respectively. Innovative means of engagement were used in 42% (eg, virtual or augmented reality or geolocation-based reminders). Apps included an average of 2.4 out of 10 of the IMS functionality criteria (range, 0-8). The mean MARS score was 3.2 ± 0.5 out of 5, and 68% had a minimum acceptability score of 3. Two had been tested or trialed.ConclusionsAlthough many hand hygiene apps exist, few provide content on best practice. Many did not meet the minimum acceptability criterion for quality or were formally trialed or tested. Research should assess the feasibility and effectiveness of hand hygiene apps (especially within healthcare settings), including when and how they "work." We recommend that future apps to support hand hygiene practice are developed with infection prevention and control experts and align with best practice. Robust research is needed to determine which innovative methods of engagement create "sticky" apps.

Project description:Hand hygiene (HH) is the most successful intervention for hospital infection control. HH rubs with residual action are desired. This study aimed to compare the efficacy of alcohol (A-HH) and lactic acid (LA-HH) rubs, with the latter being marketed as having residual activity. We investigated reductions in bacterial colony-forming units (CFUs), prevalence of antimicrobial-resistant (AMR) organisms, and risk factors for increased counts on the hands of veterinary staff. A randomized, crossover study (53 individuals) was performed in a referral veterinary teaching hospital. Hand plates were taken before, immediately after, and 6 hours after HH. A blinded investigator counted CFUs per plate. Methicillin-resistant Staphylococcus aureus/pseudintermedius (MRSA/MRSP), Enterobacteriaceae, and Pseudomonas species (spp.) were characterized. Gender, profession, time point, and HH product were included as variables within multivariable analyses. A significant reduction in bacterial CFU was seen immediately after A-HH rub application (p < 0.001); however, neither product showed any significant residual action. Veterinarians had higher bacterial CFUs than nurses (p = 0.005); contact with patients, rather than the environment, was also associated with higher counts (p < 0.001). MRSA, MRSP, Enterobacteriaceae spp., and Pseudomonas spp. were detected on 7%, 2%, 14%, and 2% of study participant's hands (n = 208 samples), respectively. Frequent HH administration using an A-HH rub was effective at reducing bacterial CFU on hands in vivo in this veterinary hospital setting, but its use needs further encouragement in veterinary staff. The high prevalence of antimicrobial bacteria on hands is of concern; they might act as reservoirs for patients, the environment, and in-contact people.

Project description:IntroductionHealthcare-acquired infections are infections that patients acquire while receiving treatment for a medical or surgical condition and can occur in all care facilities. Hospital-acquired infections and the spread of antimicrobial resistance can be reduced by implementing proper preventive measures, including hand hygiene.AimThis study aimed to assess nurses' knowledge and attitudes toward hand hygiene guidelines in Najran city, determine compliance levels, identify factors contributing to non-compliance, and provide recommendations for interventions to improve hand hygiene practices and reduce healthcare-associated infections risk.Subject and methodsThis cross-sectional study was conducted among nurses working in the selected government hospitals in Najran City, Saudi Arabia. A self-administered questionnaire was distributed among the targeted nurses using an online survey. The questionnaire includes socio-demographic characteristics such as age, gender, and marital status. The questionnaire had 25 items to measure knowledge, 10 to measure attitude, 6 to measure practices, and 4 to measure the impact of COVID-19 on hand hygiene practices.ResultsAmong the 386 nurses recruited, 88.3% were females, and 25.6% were aged between 31 to 35 years old. Overall, good knowledge, positive attitude, and good practice levels were found in 42.5, 48.4, and 94%, respectively. The common factor influencing hand hygiene practice was the prevention of cross-infection (88.1%). The total knowledge score mean was 18 ± 3.4 (highest possible score: 25). The total attitude score mean was 37.5 ± 6.1 (highest possible score: 50). The total practice score mean was 26.9 ± 2.8 (highest possible score: 30). A higher score indicates higher KAP of hand hygiene. Factors associated with increased KAP were being older in age (Z = 6.446; p < 0.001), gender female (Z = 9.869; p < 0.001), being a Filipino nurse (H = 117.8; p < 0.001), working in a surgery department (H = 28.37; p < 0.001), having more than 10 years of experience (Z = 6.903; p < 0.001), living in shared accommodation (H = 87.22; p < 0.001), having associated chronic disease (Z = 4.495; p < 0.001), and receiving formal training in hand hygiene (Z = 2.381; p = 0.017). There was a positive highly statistically significant correlation between knowledge score and attitude score (r = 0.556), between knowledge score and practices score (r = 0.303), and between attitude score and practices score (r = 0.481).ConclusionIn light of the results, we can say that the nurses' knowledge, attitude, and practice in regards to hand hygiene were deemed acceptable. We noticed that female nurses who were older and had more experience, as well as those who had received formal hand hygiene training, displayed better KAP compared to their counterparts. Moreover, we found a significant and positive correlation between the scores for knowledge, attitude, and practice. Nonetheless, additional research is necessary to establish the extent of KAP concerning hand hygiene.

Project description:The German "Clean Hands Campaign" (an adaptation of the WHO "Clean Care is Safer Care" programme) to promote hand hygiene among hospital personnel at Hannover Medical School (MHH, Medizinische Hochschule Hannover), known as Aktion Saubere Hände (ASH), met with initial success. By 2013, however, compliance rates with hygienic hand disinfection in the hospital's ten intensive care units (ICUs) and two hematopoietic stem cell transplantation units (HSCTUs) had relapsed to their initial levels (physicians: 48%; nurses: 56%). The cluster- randomized controlled trial PSYGIENE was conducted to investigate whether interventions tai - lored in ways suggested by research in behavioral psychology might bring about more sustainable improvements than the ASH.The "Health Action Process Approach" (HAPA) compliance model specifies key psychological determinants of compliance. These determinants were assessed among health care workers in the ICUs and HSCTUs of the MHH by questionnaire (response rates: physicians: 71%; nurses: 63%) and by interviews of the responsible ward physicians and head nurses (100%). In 2013, 29 tailored behavior change techniques were implemented in educational training sessions and feedback discussions in the six wards that constituted the intervention arm of the trial, while ASH training sessions were provided in the control arm. The compliance rates for 2014 and 2015 (the primary outcomes of the trial) were determined by nonparticipating observation of hygienic hand disinfection, in accordance with the World Health Organization's gold standard.The two groups did not differ in their baseline compliance rates in 2013 (intervention: 54%, control: 55%, p = 0.581). The tailored interventions led to increased compliance in each of the two follow-up years (2014: 64%, p<0.001; 2015: 70%, p = 0.001), while the compliance in the control arm increased to 68% in 2014 (p<0.001) but fell back to 64% in 2015 (p = 0.007). The compliance increases from 2013-2015 and the compliance rate in 2015 were higher in the intervention arm (p<0.005). This was mainly attributable to the nurses' behavior, as the corresponding parameters for physicians did not differ significantly between the two study arms in stratified analysis.Tailored interventions based on behavioral psychology principles led to more sustainable increases in compliance with hand hygiene guidelines than ASH training sessions did. This was true among nurses, and thus also for hospital ward personnel as a whole (i.e., nurses and physicians combined). Further studies are needed to identify more target group-specific interventions that may improve compliance among physicians.

Project description:BackgroundHand hygiene and aseptic techniques are essential preventives in combating hospital-acquired infections. However, implementation of these strategies in the operating room remains suboptimal. There is a paucity of intervention studies providing detailed information on effective methods for change. This study aimed to evaluate the process of implementing a theory-driven knowledge translation program for improved use of hand hygiene and aseptic techniques in the operating room.MethodsThe study was set in an operating department of a university hospital. The intervention was underpinned by theories on organizational learning, culture and person centeredness. Qualitative process data were collected via participant observations and analyzed using a thematic approach.ResultsDoubts that hand-hygiene practices are effective in preventing hospital acquired infections, strong boundaries and distrust between professional groups and a lack of psychological safety were identified as barriers towards change. Facilitated interprofessional dialogue and learning in "safe spaces" worked as mechanisms for motivation and engagement. Allowing for the free expression of different opinions, doubts and viewing resistance as a natural part of any change was effective in engaging all professional categories in co-creation of clinical relevant solutions to improve hand hygiene.ConclusionEnabling nurses and physicians to think and talk differently about hospital acquired infections and hand hygiene requires a shift from the concept of one-way directed compliance towards change and learning as the result of a participatory and meaning-making process. The present study is a part of the Safe Hands project, and is registered with ClinicalTrials.gov (ID: NCT02983136 ). Date of registration 2016/11/28, retrospectively registered.

Project description:BackgroundHand hygiene prescriptions are the most important measure in the prevention of hospital-acquired infections. Yet, compliance rates are generally below 50% of all opportunities for hand hygiene. This study aims at evaluating the short- and long-term effects of two different strategies for promoting hand hygiene in hospital nurses.Methods/designThis study is a cluster randomised controlled trial with inpatient wards as the unit of randomisation. Guidelines for hand hygiene will be implemented in this study. Two strategies will be used to improve the adherence to guidelines for hand hygiene. The state-of-the-art strategy is derived from the literature and includes education, reminders, feedback, and targeting adequate products and facilities. The extended strategy also contains activities aimed at influencing social influence in groups and enhancing leadership. The unique contribution of the extended strategy is built upon relevant behavioural science theories. The extended strategy includes all elements of the state-of-the-art strategy supplemented with gaining active commitment and initiative of ward management, modelling by informal leaders at the ward, and setting norms and targets within the team. Data will be collected at four points in time, with six-month intervals. An average of 3,000 opportunities for hand hygiene in approximately 900 nurses will be observed at each time point.DiscussionPerforming and evaluating an implementation strategy that also targets the social context of teams may considerably add to the general body of knowledge in this field. Results from our study will allow us to draw conclusions on the effects of different strategies for the implementation of hand hygiene guidelines, and based on these results we will be able to define a preferred implementation strategy for hospital based nursing.Trial registrationThe study is registered as a Clinical Trial in ClinicalTrials.gov, dossier number: NCT00548015.

Project description:Handwashing is one of the most effective and low-cost public health measures. However, it is often not practiced frequently enough or correctly by the public. Young adults in particular have poorer intentions to wash their hands, frequency of handwashing, and sanitizer use compared to other age groups. Therefore, there is a need to identify barriers and facilitators affecting hand hygiene within this group. The objective of this qualitative study was to apply the Theoretical Domains Framework to explore factors which influence hand hygiene among young adults aged 18 to 25 years old. An online questionnaire (n = 37) and thematic analysis were used to generate 3 overarching themes. The main findings indicated internal factors such as knowledge and intentions; interpersonal factors such as social norms; and environmental factors such as reminders, cues, accessibility, and cleanliness of handwashing facilities determined the level of hand hygiene practiced among young adults. The findings suggest that behavior change techniques such as social comparisons and tailored messaging to suit the needs of young adults may be more effective at increasing hand hygiene.

Project description:BackgroundHand hygiene (HH), a cornerstone in infection prevention and control, lacks quality in emergency medical services (EMS). HH improvement includes both individual and institutional aspects, but little is known about EMS providers' HH perception and motivations related to HH quality. Therefore, we aimed to investigate the HH perception and assess potential factors related to self-reported HH compliance among the EMS cohort.MethodsA cross-sectional, self-administered questionnaire consisting of 24 items (developed from the WHOs Perception Survey for Health-Care Workers) provided information on demographics, HH perceptions and self-reported HH compliance among EMS providers from Denmark.ResultsOverall, 457 questionnaires were answered (response rate 52%). Most respondents were advanced-care providers, males, had > 5 years of experience, and had received HH training < 3 years ago. HH was perceived a daily routine, and the majority rated their HH compliance rate ≥ 80%. Both infection severity and the preventive effect of HH were acknowledged. HH quality was perceived important to colleagues and patients, but not as much to managers. Access to supplies, simple instructions and having or being "a good example" were perceived most effective to improve HH compliance. Self-reported HH compliance was associated with years of experience and perceptions of HCAI's impact on patient outcome, HH's preventive effect, organizational priority, HH's importance to colleagues and patients, and the effort HH requires (p ≤ 0.05).ConclusionDanish EMS providers acknowledged the impact of infections and the preventive effect of HH, and perceived access to HH supplies at the point of care, having or being "a good example" and simple instructions effective to improve HH compliance. Moreover, several behavioral-, normative- and control beliefs were associated with self-reported HH compliance, and thus future improvement strategies should be multimodal.

Project description:BackgroundImproving hand hygiene in hospitals is the most efficient method to prevent healthcare-associated infections. The hand hygiene behavior of hospital patients and visitors is not well-researched, although they pose a risk for the transmission of pathogens. Therefore, the present study had three aims: (1) Finding a suitable theoretical model to explain patients' and visitors' hand hygiene practice; (2) Identifying important predictors for their hand hygiene behavior; and (3) Comparing the essential determinants of hand hygiene behavior between healthcare professionals from the literature to our non-professional sample.MethodsIn total N = 1,605 patients and visitors were surveyed on their hand hygiene practice in hospitals. The employed questionnaires were based on three theoretical models: a) the Theory of Planned Behavior (TPB); b) the Health Action Process Approach (HAPA); and c) the Theoretical Domains Framework (TDF). Structural equation modeling was used to analyze the data. To compare our results to the determinants of healthcare workers' hand hygiene behavior, we searched for studies that used one of the three theoretical models.ResultsAmong patients, 52% of the variance in the hand hygiene behavior was accounted for by the TDF domains, 44% by a modified HAPA model, and 40% by the TPB factors. Among visitors, these figures were 59%, 37%, and 55%, respectively. Two clusters of variables surfaced as being essential determinants of behavior: self-regulatory processes and social influence processes. The critical determinants for healthcare professionals' hand hygiene reported in the literature were similar to the findings from our non-professional sample.ConclusionsThe TDF was identified as the most suitable model to explain patients' and visitors' hand hygiene practices. Patients and visitors should be included in existing behavior change intervention strategies. Newly planned interventions should focus on targeting self-regulatory and social influence processes to improve effectiveness.
