Compliance with handwashing and barrier precautions

All Hands on Deck: Sustaining Improved Hand Hygiene Compliance in the Operating Room

Hand hygiene is an essential component of infection prevention in the health care setting. Despite diligent efforts, clinicians can be susceptible to hand hygiene misses in fast-paced, complex environments such as the operating room due to systemic factors such as the physical environment, workflow, and sporadic interactions with other personnel. Through the use of human factors and resilience engineering concepts, work-as-done were studied to identify barriers to hand hygiene compliance in the operating rooms of a pediatric hospital in an urban area. The saliency, effort, expectancy, value model was applied to design a multifaceted intervention that resulted in a sustained 95% hand hygiene compliance.

User-centred participatory design of visual cues for isolation precautions

Background

Isolation precautions are intended to prevent transmission of infectious agents, yet healthcare provider (HCP) adherence remains suboptimal. This may be due to ambiguity regarding the required precautions or to cognitive overload of HCPs. In response to the challenge of changing HCP behaviour, increasing attention should be paid to the role of engineering controls and facility design that incorporate human factors elements. In the current study, we aimed to develop an isolation precaution signage system that provides visual cues, serves as a cognitive aid at the point of care, and removes ambiguity regarding which precautions are necessary (e.g. masks, gowns, gloves, single rooms) when caring for isolated patients.

Methods

We employed a user-centred, participatory design approach in which HCPs were actively involved in generating an isolation precaution signage system based on human factors design principles. HCPs were purposefully sampled for each design phase to include a representative sample of potential system users. We conducted front-end analysis through interviews and observations to identify challenges related to the existing signage and to establish design requirements for new signage. This was followed by the creation of user personas, design thinking workshops, and prototyping, which then underwent iterative cycles of evaluation. Graphical symbols were developed and tested for comprehensibility.

Results

Front-end analysis revealed several barriers to use of the current signage system such as unclear target audience, low signal-to-noise ratio, and ambiguity regarding the applicable precautions. A comprehensive list of design requirements was generated. The project ultimately resulted in a collection of validated, comprehensible symbols and signs for contact, droplet, and airborne isolation, as well as the identification of several systems-level solutions for work re-organisation to improve compliance with isolation precautions.

Conclusions

The introduction of visual cues in the form of signage offers a promising opportunity to make guidelines available directly at the frontline. Anecdotal evidence based on observations and interviews with HCP have shown that the current solution is superior to previous isolation signage. User-centred participatory design was a useful approach that holds potential for further improving design in healthcare settings.

A qualitative evaluation of the role of simulation in policy development for service improvement

Objective

To evaluate the efficacy of simulation-based techniques to prospectively assess developing polices prior to implementation.

Methods

A self-selected sample of nursing staff from a local, acute hospital reviewed a draft intravenous drug administration policy before simulating drug administration of either an infusion or direct injection. The participants completed a postsimulation questionnaire regarding the new policy and simulation, took part in a semistructured interview and were observed during the simulation with their consent.

Results

10 staff attended the simulation. The emergent themes identified a wide range of factors relating to the everyday usability and practicalities of the policy. There were issues surrounding inconsistent language between different clinical teams and training requirements for the new policy.

Conclusion

Simulation, using simple scenarios, allows the safe evaluation of new policies before publication to ensure they are appropriate for front-line use. It engages staff in user-centred design in their own healthcare system.

Predicting and explaining behavioral intention and hand sanitizer use among US Army soldiers

BACKGROUND

Using hand sanitizers can reduce bacterial contamination and is an efficient and inexpensive method of preventing infections. The purpose of this study was to explore the behavioral intention (low and absolute), attitudes, subjective norms, and perceived behavioral control of hand sanitizer use among US Army soldiers.

METHODS

A questionnaire was developed following an expert panel (N = 5) review and 2 pilot studies (N = 35) to ensure questionnaire validity and clarity. Surveys were distributed among nontrainee soldiers during lunch periods. A total of 201 surveys were collected.

RESULTS

Results indicated that attitudes, subjective norms, and perceived behavioral controls explained 64% of the variance in behavioral intention. Attitude remained the strongest predictor of behavior (β = 0.70, P < .01), followed by subjective norms (β = 0.18; P < .01), with significant differences between low and absolute intenders.

CONCLUSIONS

Soldiers with absolute intention to use hand sanitizers hold significantly different behavioral and normative beliefs than low intenders. Other soldiers create negative social pressure about using hand sanitizers, indicating that if other soldiers use hand sanitizers, they will refuse to do so. Intervention to ensure use of hand sanitizer should focus on strengthening behavioral and normative beliefs among low intenders. This should increase the overall well being of the military.

Flowers in the clinical setting: Infection risk or workload issue?

Healthcare-associated infection has become a topic of interest to the general public in the United Kingdom, kindled by media accounts of poor hygiene and the risks of cross-infection. In the spring of 2003, one of the broadsheet newspapers published an article debating the hygiene and infection risks associated with cut flowers brought into clinical areas. There were reports that in many wards this practice is no longer allowed because flowers are considered dirty, trigger allergies and the water is regarded as harbouring bacteria, leading to infection.

Discussion with infection control experts revealed that questions concerning the risks associated with flowers are among those most frequently asked. A literature search was undertaken to establish the evidence base, and a questionnaire study was performed with a purposive sample of 39 nurses to document how they manage flowers in the clinical setting. Empirical research studies were difficult to obtain. Early work had been undertaken to explore the added workload associated with maintaining fresh flowers and ways of reducing it. Later studies revealed that the water in flower vases and cut plants both harbour large numbers of Gram-negative pathogens.

Cross-infection and cases of clinical infection have never been documented, thus flowers have not been considered a risk, except to severely immunocompromised patients. However, scrutiny of the more general literature relating to Gram-negative sepsis indicated that cross-infection has been documented from a wide range of environmental sources and it is possible that it may take place from flowers via the hands of staff if they are not properly decontaminated. Nevertheless, these risks can be reduced by scrupulous attention to hand hygiene and commonsense measures.

Over half the nurses (n = 26, 66.6%) thought that flowers constituted an infection risk and a number of other disadvantages were cited. Most nurses (n = 31, 80%) were not in favour of flowers in the clinical setting and there was some evidence that this attitude was related to the amount of work generated, with infection and other risks used to justify it. Interest in the topic was considerable and the results can be used to stimulate discussion and emphasise the importance of controlling health-related infection.

Antiseptic use in the neonatal intensive care unit - a dilemma in clinical practice: An evidence based review

Infants in the neonatal intensive care unit are highly susceptible to healthcare associated infections (HAI), with a substantial impact on mortality, morbidity and healthcare costs. Effective skin disinfection with topical antiseptic agents is an important intervention in the prevention or reduction of HAI. A wide array of antiseptic preparations in varying concentrations and combinations has been used in neonatal units worldwide. In this article we have reviewed the current evidence of a preferred antiseptic of choice over other agents for topical skin disinfection in neonates. Chlorhexidine (CHG) appears to be a promising antiseptic agent; however there exists a significant concern regarding the safety of all agents used including CHG especially in preterm and very low birth weight infants. There is substantial evidence to support the use of CHG for umbilical cord cleansing and some evidence to support the use of topical emollients in reducing the mortality in infants born in developing countries. Well-designed large multicentre randomized clinical trials are urgently needed to guide us on the most appropriate and safe antiseptic to use in neonates undergoing intensive care, especially preterm infants.

Implementation of an innovative hands-on training to improve adherence to hygiene rules: A feasibility Study

BACKGROUND

Hospital-acquired infections (HAI) still pose a major problem in inpatient care. The single most important measure for preventing HAIs is to improve adherence to hand hygiene among health care professionals.

OBJECTIVE

To assess the feasibility of an innovative hands-on training to improve adherence to hygiene rules under standardized and under real life conditions.

DESIGN

Before-after controlled cohort trial to assess the feasibility of implementing an innovative hands-on training to improve hand hygiene adherence.

SETTING

Large university hospital in Germany.

PARTICIPANTS

Fifty trained nurses from three wards with an average age of 32years (±10.22years) and an average vocational experience of 6.85years (±7.54years).

METHODS

The intervention consisted of a hands-on training in the skills lab of the University of Cologne complemented by a 12-week observation period before and after the training on participating wards. The training comprised important skills with respect to hand hygiene, venipuncture, dressing changes of central venous catheters, preparation of IV infusions, and donning of gloves using sterile technique. A communication training was included to enable nurses to enforce hygiene rules in their collaboration with peers and physicians. The intervention was taught in small groups with a wide array of interactive teaching methods. It was evaluated using the objective structured clinical examination (OSCE) format. Observations were conducted by a trained infection control nurse.

RESULTS

Before (after) the intervention 622 (612) occasions of hand hygiene were documented. A highly significant improvement in hygiene compliance was observed pre- and post-intervention (64.3% vs. 79.2%; p≤0.0001). The OSCE evaluation showed significant improvements in all subscales.

CONCLUSION

The developed and conducted hands-on training seems feasible and is successful in significantly improving adherence to hygiene rules under standardized and real life conditions. Whether the effect is stable over time is subject to further investigation.

Hand hygiene knowledge and perceptions among anesthesia providers

BACKGROUND

Health care worker compliance with hand hygiene guidelines is an important measure for health care-associated infection prevention, yet overall compliance across all health care arenas remains low. A correct answer to 4 of 4 structured questions pertaining to indications for hand decontamination (according to types of contact) has been associated with improved health care provider hand hygiene compliance when compared to those health care providers answering incorrectly for 1 or more questions. A better understanding of knowledge deficits among anesthesia providers may lead to hand hygiene improvement strategies. In this study, our primary aims were to characterize and identify predictors for hand hygiene knowledge deficits among anesthesia providers.

METHODS

We modified this previously tested survey instrument to measure anesthesia provider hand hygiene knowledge regarding the 5 moments of hand hygiene across national and multicenter groups. Complete knowledge was defined by correct answers to 5 questions addressing the 5 moments for hand hygiene and received a score of 1. Incomplete knowledge was defined by an incorrect answer to 1 or more of the 5 questions and received a score of 0. We used a multilevel random-effects XTMELOGIT logistic model clustering at the respondent and geographic location for insufficient knowledge and forward/backward stepwise logistic regression analysis to identify predictors for incomplete knowledge.

RESULTS

The survey response rates were 55.8% and 18.2% for the multicenter and national survey study groups, respectively. One or more knowledge deficits occurred with 81.6% of survey respondents, with the mean number of correct answers 2.89 (95% confidence interval, 2.78- 2.99). Failure of providers to recognize prior contact with the environment and prior contact with the patient as hand hygiene opportunities contributed to the low mean. Several cognitive factors were associated with a reduced risk of incomplete knowledge including providers responding positively to washing their hands after contact with the environment (odds ratio [OR] 0.23, 0.14-0.37, P < 0.001), disinfecting their environment during patient care (OR 0.54, 0.35-0.82, P = 0.004), believing that they can influence their colleagues (OR 0.43, 0.27-0.68, P < 0.001), and intending to adhere to guidelines (OR 0.56, 0.36-0.86, P = 0.008). These covariates were associated with an area under receiver operator characteristics curve of 0.79 (95% confidence interval, 0.74-0.83).

CONCLUSIONS

Anesthesia provider knowledge deficits around to hand hygiene guidelines occur frequently and are often due to failure to recognize opportunities for hand hygiene after prior contact with contaminated patient and environmental reservoirs. Intraoperative hand hygiene improvement programs should address these knowledge deficits. Predictors for incomplete knowledge as identified in this study should be validated in future studies.

Multicenter Intervention Program to Increase Adherence to Hand Hygiene Recommendations and Glove Use and to Reduce the Incidence of Antimicrobial Resistance

Objective.

To determine whether a multimodal intervention could improve adherence to hand hygiene and glove use recommendations and decrease the incidence of antimicrobial resistance in different types of healthcare facilities.

Design.

Prospective, observational study performed from October 1, 1999, through December 31, 2002. We monitored adherence to hand hygiene and glove use recommendations and the incidence of antimicrobial-resistant bacteria among isolates from clinical cultures. We evaluated trends in and predictors for adherence and preferential use of alcohol-based hand rubs, using multivariable analyses.

Setting.

Three intervention hospitals (a 660-bed acute and long-term care hospital, a 120-bed community hospital, and a 600-bed public teaching hospital) and a control hospital (a 700-bed university teaching hospital).

Intervention.

At the intervention hospitals, we introduced or increased the availability of alcohol-based hand rub, initiated an interactive education program, and developed a poster campaign; at the control hospital, we only increased the availability of alcohol-based hand rub.

Results.

We observed 6,948 hand hygiene opportunities. The frequency of hand hygiene performance or glove use significantly increased during the study period at the intervention hospitals but not at the control hospital; the maximum quarterly frequency of hand hygiene performance or glove use at intervention hospitals (74%, 80%, and 77%) was higher than that at the control hospital (59%). By multivariable analysis, preferential use of alcohol-based hand rubs rather than soap and water for hand hygiene was more likely among workers at intervention hospitals compared with nonintervention hospitals (adjusted odds ratio, 4.6 [95% confidence interval, 3.3-6.4]) and more likely among physicians (adjusted odds ratio, 1.4 [95% confidence interval, 1.2-1.8]) than among nurses at intervention hospitals. A significantly reduced incidence of antimicrobial-resistant bacteria among isolates from clinical culture was found at a single intervention hospital, which had the greatest increase in the frequency of hand hygiene performance.

Conclusions.

During a 3-year period, a multimodal intervention program increased adherence to hand hygiene recommendations, especially to the use of alcohol-based hand rubs. In one hospital, a concomitant reduction was found in the incidence of antimicrobial-resistant bacteria among isolates from clinical cultures.

Does the Architecture of Hospital Facilities Influence Nosocomial Infection Rates? A Systematic Review

Objective:

To review the evidence regarding the effects of interventions to improve hospital design and construction on the occurrence of nosocomial infections.

Methods:

Systematic review of experimental and non-experimental, architectural intervention studies in intensive care units (ICUs), surgical departments, isolation units, and hospitals in general. The studies dated from 1975, and were in English, French, German, Italian, and Spanish. Regardless of format, the studies were identified through seven medical databases, reference lists, and expert consultation.

Results:

One hundred seventy-eight scientific articles were identified; however, none of these described a meta-analy-sis, systematic review, or randomized, controlled trial. Most of the articles were categorized at the lowest level of evidence (expert judgment or consensus statements). Only 17 described completed concurrent or historical cohort studies matching the inclusion criteria (ICUs, 9; surgical departments, 4; isolation units, 2; hospitals in generai, 2). The interventions generally included a move to other premises or renovation. However, in many studies, the staff-to-patient ratio was also improved. Some studies showed lower infection rates after intervention, but this finding cannot be generalized because of confounding and fre-quently small study populations.

Conclusions:

The lack of stringent evidence linking hospital design and construction with the prevention of nosocomial infection is partly attributable to the multifactorial nature of these infections, and some improvement will be seen if basic conditions such as the availability of sufficient space, isolation capac-ity, and facilities for handwashing are met. However, to our knowledge, other factors, especially the improper hand hygiene of medical staff, have greater impact.

Factors Associated with Hand Hygiene Compliance at a Tertiary Care Teaching Hospital

Objective.

To identify factors associated with hand hygiene compliance during a multiyear period of intervention.

Design.

Observational study.

Setting.

A 719-bed tertiary care teaching hospital.

Participants.

Nursing, physician, technical, and support staff.

Methods.

Light-duty staff performed hand hygiene observations during the period July 2008-December 2012. Infection control implemented hospital-wide hand hygiene initiatives, including education modules; posters and table tents; feedback to units, medical directors and the executive board; and an increased number of automated alcohol hand hygiene product dispensers.

Results.

There were 161,526 unique observations; overall compliance was 83%. Significant differences in compliance were observed between physician staff (78%) and support staff (69%) compared with nursing staff (84%). Pediatric units (84%) and intensive care units (84%) had higher compliance than did medical (82%) and surgical units (81%). These findings persisted in the controlled multivariate model for noncompliance. Additional factors found to be significant in the model included greater compliance when healthcare workers were leaving patient rooms, when the patient was under contact precautions, and during the evening shift. The overall rate of compliance increased from 60% in the first year of observation to a peak of 96% in the fourth year, and it decreased to 89% in the final year, with significant improvements occurring in each of the 4 professional categories.

Conclusions.

A multipronged hand hygiene initiative is effective in increasing compliance rates among all categories of hospital workers. We identified a variety of factors associated with increased compliance. Additionally, we note the importance of continuous interventions in maintaining high compliance rates.

Multidrug-Resistant Bacteria Infection Control: Study of Compliance With Isolation Precautions in a Paris University Hospital

Isolation practices in a university hospital were analyzed for 137 patients with multidrug-resistant bacteria. Isolation was ordered in writing by physicians for 40% and instituted by nurses for 60%; 74% were isolated. Compliance depended on physician ordering in writing (odds ratio, 36.3; 95% confidence interval, 4.8-274.9). Nurses complied best with hand washing.

Handwashing Program for the Prevention of Nosocomial Infections in a Neonatal Intensive Care Unit

Objective:

To evaluate the effects of a hand hygiene program on compliance with hand hygiene and the rate of nosocomial infections in a neonatal intensive care unit (NICU).

Design:

Open trial.

Setting:

A level-III NICU in a teaching hospital.

Participants:

Nurses, physicians, and other healthcare workers in the NICU.

Interventions:

A multimodal campaign for hand hygiene promotion was conducted beginning in September 1998. This program consisted of formal lectures, written instructions and posted reminders regarding hand hygiene and proper handwashing techniques, covert observation, financial incentives, and regular group feedback on compliance. Surveillance of handwashing compliance and nosocomial infections before and during the program was analyzed.

Results:

Overall compliance with hand hygiene improved from 43% at baseline to 80% during the promotion program. The rate of nosocomial infections decreased from 15.13 to 10.69 per 1,000 patient-days (P= .003) with improved handwashing compliance. In particular, respiratory tract infections decreased from 3.35 to 1.06 per 1,000 patient-days during the handwashing campaign (P= .002). Furthermore, the correlation between nosocomial infection of the respiratory tract and handwashing compliance also reached statistical significance (r= -0.385;P= .014).

Conclusions:

Improved compliance with handwashing was associated with a significant decrease in overall rates of nosocomial infection and respiratory infections in particular. Washing hands is a simple, economical, and effective method for preventing nosocomial infections in the NICU

Prevention of Infections Associated With Permanent Cardiac Antiarrhythmic Devices by Implementation of a Comprehensive Infection Control Program

Objective:

To implement a comprehensive infection control (IC) program for prevention of cardiac device-associated infections (CDIs).

Design:

Prospective before-after trial with 2 years of follow-up.

Setting:

A tertiary-care, university-affiliated medical center.

Patients:

A consecutive sample of all adults undergoing cardiac device implantation between 1997 and 2002.

Intervention:

An IC program was implemented during late 2001 and included staff education, preoperative modification of patient risk factors, intraoperative control of strict aseptic technique, surgical scrubbing and attire, control of environmental risk factors, optimization of antibiotic prophylaxis, postoperative wound care, and active surveillance. The clinical endpoint was CDI rates.

Results:

Between 1997 and 2000, there were 7 CDIs among 725 procedures (mean annual CDI incidence, 1%). During the first 9 months of 2001, there were 7 CDIs among 167 procedures (4.2%; P = .007): CDIs increased from 7 among 576 to 3 among 124 following pacemaker implantation (P = .39) and from 0 among 149 to 4 among 43 following cardioverter-defibrillator implantation (P = .002). Of the 14 CDIs, 5 involved superficial wounds, 7 involved deep wounds, and 2 involved endocarditis. Following intervention, there were no cases of CDI among 316 procedures during 24 months of follow-up (4.2% reduction; P = .0005).

Conclusions:

We observed a high CDI rate associated with substantial morbidity. IC measures had an impact on CDI. Although the relative weight of each measure in the prevention of CDI remains unknown, our results suggest that implementation of a comprehensive IC program is feasible and efficacious in this setting.

Rapid Antibacterial Activity of 2 Novel Hand Soaps: Evaluation of the Risk of Development of Bacterial Resistance to the Antibacterial Agents

Objective.

To evaluate the antimicrobial efficacy of and risk of organisms developing resistance to 2 novel hand soaps: (1) a soap containing triclosan, polyhexamethylene biguanide, and benzethonium chloride added to a soap base (TPB soap); and (2) a soap containing farnesol, polyhexamethylene biguanide, and benzethonium chloride added to a soap base (FPB soap). Tests also included soaps containing only triclosan.

Design.

The risk of emergence of resistant bacterial mutants was investigated by determining the susceptibility changes after repeated exposure of bacteria to the drugs and soaps in vitro. The effectiveness of the soaps was evaluated using an in vitro tube dilution method, a volunteer method (the ASTM standard), and 2 pig skin methods.

Results.

The minimum inhibitory concentration and minimum bactericidal concentration of triclosan against Staphylococcus, aureus increased 8- to 62.5-fold, whereas those of TPB and FPB (both alone and in soap) were unchanged. In vitro, TPB and FPB soaps produced higher log10 reductions in colony-forming units of all tested organisms (4.95-8.58) than did soaps containing triclosan alone (0.29-4.86). In the test using the pig skin and volunteer methods, TPB soap produced a higher log10 reduction in colony-forming units (3.1-3.3) than did the soap containing triclosan alone (2.6-2.8).

Conclusion.

The results indicate that TPB and FPB soaps may provide superior rapid and broad-spectrum efficacy with a lower risk of organisms developing resistance than do soaps containing triclosan alone. Pig skin methods may be used to predict the efficacy of antibacterial soaps in the rapid disinfection of contaminated hands. Hand washing with TPB and FPB soaps by healthcare workers and the general population may reduce the transmission of pathogens, with a lower risk of promoting the emergence of resistant organisms.

Improving hand hygiene at eight hospitals in the United States by targeting specific causes of noncompliance

BACKGROUND

Hospitals and infection prevention specialists have attempted to achieve high levels of compliance with hand hygiene protocols for many decades. Despite these efforts, measured performance is disappointingly low.

METHODS

The Joint Commission Center for Transforming Healthcare convened teams of experts in performance improvement and infectious disease from eight hospitals for its hand hygiene quality improvement project, which was conducted from December 2008 through September 2010. Together, they used Lean, Six Sigma, and change management methods to measure the magnitude of hand hygiene noncompliance, assess specific causes of hand hygiene failures, develop and test interventions targeted to specific causes, and sustain improved levels of performance.

RESULTS

At baseline, hand hygiene compliance averaged 47.5% across all eight hospitals. Initial data revealed 41 different causes of hand hygiene noncompliance, which were condensed into 24 groups of causes. Key causes varied greatly among the hospitals. Each hospital developed and implemented specific interventions targeted to its most important causes of hand hygiene noncompliance. The improvements were associated with a 70.5% increase in compliance across the eight hospitals from 47.5% to 81.0% ( p < .001), a level of performance that was sustained for 11 months through the end of the project period.

CONCLUSION

Lean, Six Sigma, and change management tools were used to identify specific causes of hand hygiene noncompliance at individual hospitals and target specific interventions to remedy the most important causes. This approach allowed each hospital to customize its improvement efforts by focusing on the causes most prevalent at its own facility. Such a targeted approach may be more effective, efficient, and sustainable than "one-size-fits-all" strategies.

Success of a multimodal program to improve hand hygiene compliance

The purpose of this article was to describe the successful implementation of a quality improvement initiative focusing on a hand hygiene program that used the multimodal interventions of tailored education, monthly feedback, and reminders. Compliance rates improved from July 2011 to December 2012 by 57.4%. Efforts are continuing to ensure program sustainability.

Predictors of health care professionals' attitudes towards involvement in safety-relevant behaviours

BACKGROUND

Patients can make valuable contributions towards promoting the safety of their health care. Health care professionals (HCPs) could play an important role in encouraging patient involvement in safety-relevant behaviours. However, to date factors that determine HCPs' attitudes towards patient participation in this area remain largely unexplored.

OBJECTIVE

To investigate predictors of HCPs' attitudes towards patient involvement in safety-relevant behaviours.

DESIGN

A 22-item cross-sectional fractional factorial survey that assessed HCPs' attitudes towards patient involvement in relation to two error scenarios relating to hand hygiene and medication safety.

SETTING

Four hospitals in London

PARTICIPANTS

  Two hundred sixteen HCPs (116 doctors; 100 nurses) aged between 21 and 60 years (mean: 32): 129 female.

OUTCOME MEASURES

Approval of patient's behaviour, HCP response to the patient, anticipated effects on the patient-HCP relationship, support for being asked as a HCP, affective rating response to the vignettes.

RESULTS

HCPs elicited more favourable attitudes towards patients intervening about a medication error than about hand sanitation. Across vignettes and error scenarios, the strongest predictors of attitudes were how the patient intervened and how the HCP responded to the patient's behaviour. With regard to HCP characteristics, doctors viewed patients intervening less favourably than nurses.

CONCLUSIONS

HCPs perceive patients intervening about a potential error less favourably if the patient's behaviour is confrontational in nature or if the HCP responds to the patient intervening in a discouraging manner. In particular, if a HCP responds negatively to the patient (irrespective of whether an error actually occurred), this is perceived as having negative effects on the HCP-patient relationship.

Impact of health campaign on hand hygiene with alcohol-based hand rubs in a non-clinical setting

BACKGROUND

Hand hygiene has been acknowledged as the single most important measure to prevent nosocomial infections. Likewise, for non-clinical settings, hand hygiene is recognized as a key element to prevent the spread of infectious diseases, nevertheless poor compliance has been documented. The feasibility of hand hygiene interventions in open-community settings with adults is mostly unclear.

AIM

To investigate the acceptability and feasibility of a health campaign to promote hand hygiene with alcohol-based hand disinfectants at workplaces in a non-clinical setting.

METHODS

The surveys were conducted as part of a prospective, controlled intervention study with volunteers from the administration of the Ernst-Moritz-Arndt-University Greifswald, the municipality of Greifswald and the state of Mecklenburg-West Pomerania. Participants in the intervention group were provided with alcohol-based hand disinfection; the control group was unchanged. Eleven volunteers filled out an initial survey at the beginning of the intervention regarding demographic and health-related questions as well as questions about the type of work, and a survey after completion of the intervention to evaluate the study's impact on the participants' attitudes toward hand hygiene. Participants in the experimental group filled out a monthly questionnaire regarding their compliance with hand hygiene measures, feasibility of hand disinfection and possible side-effects.

FINDINGS

From 850 employees asked to participate, 134 were included in the study, and surveys from 129 participants (intervention: 64 vs control: 65) were accepted for analysis. Overall, datasets of 1230 person-months (79.46% of total possible follow-up surveys) were collected. Return rate and compliance remained high during the study period. Hand disinfection did not lead to skin problems in the majority of person-months. After the intervention, a majority of participants would favour a further use of hand disinfectants.

CONCLUSION

Campaigns that enforce the use of alcohol-based hand disinfectants can have a sustainable effect on the compliance with hand hygiene measures in non-clinical settings. Campaigns have been shown to be feasible and effective in the prevention of transmissible diseases, therefore employers should consider whether hand hygiene campaigns to introduce waterless hand rubs could be included in companies' health programmes.

Improvement of adherence to hand hygiene practice using a multimodal intervention program in a neonatal intensive care

Nosocomial infections are serious complications among preterm infants admitted to neonatal intensive care units (NICU). Hand hygiene is one of the most effective measures to prevent these infections. This study, performed in a tertiary level NICU, highlights the importance of a multimodal intervention program for adherence to hand hygiene. The compliance with hand hygiene among health care workers of the NICU increased significantly from 23% in the baseline assessment to 50% in the second assessment and the incidence of sepsis decreased from 13.4% to 11.3% after implementation of an intervention program.

Improving hand hygiene compliance in healthcare settings using behavior change theories: reflections

BACKGROUND

Although hand hygiene is the most effective method for preventing healthcare-associated infections, hand hygiene practice falls short in many healthcare facilities. The compliance rate is mostly linked to system design and easily accessible hand hygiene products. System change, healthcare worker motivation, and complex behavioral considerations seem to play a significant role.

SUMMARY

This article discusses the application of behavioral theories in hand hygiene promotion in a theoretical manner. The program relies on the transtheoretical model (TTM) of health behavior change, John Keller's (ARCS) Model of Motivational Design, and the theory of planned behavior (TPB). Thus, the program links attitudes and behavior to hand hygiene promotion.

CONCLUSIONS

The TTM of health behavior change helps to tailor interventions to predict and motivate individual movement across the pathway to change. A program could be based on this theory with multiple intercalations with John Keller's ARCS and the TPB. Such a program could be strengthened by linking attitudes and behavior to promote hand hygiene. The program could utilize different strategies such as organization cultural change that may increase the attention as well as fostering the movement in the ARCS stages. In addition, modeling TPB by creating peer pressure, ability to overcome obstacles, and increasing knowledge of the role of hand hygiene may lead to the desired outcome. The understanding and application of behavior change theories may result in an effective program to improve awareness and raise intention and thus may increase the potential for success of hand hygiene promotion programs.

Can a school-based hand hygiene program reduce asthma exacerbations among elementary school children?

BACKGROUND

Viral upper respiratory tract infections have been implicated as a major cause of asthma exacerbations among school-aged children. Regular hand washing is the most effective method to prevent the spread of viral respiratory tract infections, but effective hand-washing practices are difficult to establish in schools.

OBJECTIVES

This randomized controlled trial evaluated whether a standardized regimen of hand washing plus alcohol-based hand sanitizer could reduce asthma exacerbations more than schools' usual hand hygiene practices.

METHODS

This was a 2-year, community-based, randomized controlled crossover trial. Schools were randomized to usual care and then intervention (sequence 1) or intervention and then usual care (sequence 2). Intervention schools were provided with alcohol-based hand sanitizer, hand soap, and hand hygiene education. The primary outcome was the proportion of students experiencing an asthma exacerbation each month. Generalized estimating equations were used to model the difference in the marginal rate of exacerbations between sequences while controlling for individual demographic factors and the correlation within each student and between students within each school.

RESULTS

Five hundred twenty-seven students with asthma were enrolled among 31 schools. The hand hygiene intervention did not reduce the number of asthma exacerbations compared with the schools' usual hand hygiene practices (P = .132). There was a strong temporal trend because both sequences experienced fewer exacerbations during year 2 compared with year 1 (P < .001).

CONCLUSIONS

Although the intervention was not found to be effective, the results were confounded by the H1N1 influenza pandemic that resulted in substantially increased hand hygiene behaviors and resources in usual-care schools. Therefore these results should be viewed cautiously.

Self-reported reasons for hand hygiene in 3 groups of health care workers

BACKGROUND

The hands of health care workers continue to be the main vector for nosocomial infection in hospitals. The purpose of the current research was to capture the health beliefs and self-reported behaviors of US health care workers to better understand why workers avoid hand hygiene and what prompts them to wash.

METHODS

An online survey of health care workers assessed their reasons for washing their hands, reasons for not washing, and what cues prompted the decision to wash or not wash in a variety of locations.

RESULTS

The findings were that hand hygiene could be cued by an external situation but tended to be motivated internally. Hand hygiene was avoided because of situational barriers.

CONCLUSION

The reasons for performing hand hygiene can be situated in the internally motivated Theory of Planned Behavior; however, the reasons for not performing hand hygiene tend to be situational and affected by the environment. The results may be used to design programs, products, and systems that promote appropriate hand hygiene practices. Principles for design of these programs and products are provided.

Cluster randomized trial to evaluate the effect of a multimodal hand hygiene improvement strategy in primary care

OBJECTIVE

To evaluate the effectiveness of a multimodal intervention in primary care health professionals for improved compliance with hand hygiene practice, based on the World Health Organization's 5 Moments for Health Hygiene.

DESIGN

Cluster randomized trial, parallel 2-group study (intervention and control).

SETTING

Primary healthcare centers in Madrid, Spain.

PARTICIPANTS

Eleven healthcare centers with 198 healthcare workers (general practitioners, nurses, pediatricians, auxiliary nurses, midwives, odontostomatologists, and dental hygienists). Methods. The multimodal hand hygiene improvement strategy consisted of training of healthcare workers by teaching sessions, implementation of hydroalcoholic solutions, and installation of reminder posters. The hand hygiene compliance level was evaluated by observation during regular care activities in the office visit setting, at the baseline moment, and 6 months after the intervention, all by a single external observer.

RESULTS

The overall baseline compliance level was 8.1% (95% confidence interval [CI], 6.2-10.1), and the healthcare workers of the intervention group increased their hand hygiene compliance level by 21.6% (95% CI, 13.83-28.48) compared with the control group.

CONCLUSIONS

This study has demonstrated that hand hygiene compliance in primary healthcare workers can be improved with a multimodal hand hygiene improvement strategy.

Bundling hand hygiene interventions and measurement to decrease health care-associated infections

Proper performance of hand hygiene at key moments during patient care is the most important means of preventing health care-associated infections (HAIs). With increasing awareness of the cost and societal impact caused by HAIs has come the realization that hand hygiene improvement initiatives are crucial to reducing the burden of HAIs. Multimodal strategies have emerged as the best approach to improving hand hygiene compliance. These strategies use a variety of intervention components intended to address obstacles to complying with good hand hygiene practices, and to reinforce behavioral change. Although research has substantiated the effectiveness of the multimodal design, challenges remain in promoting widespread adoption and implementation of a coordinated approach. This article reviews elements of a multimodal approach to improve hand hygiene and advocates the use of a "bundled" strategy. Eight key components of this bundle are proposed as a cohesive program to enable the deployment of synergistic, coordinated efforts to promote good hand hygiene practice. A consistent, bundled methodology implemented at multiple study centers would standardize processes and allow comparison of outcomes, validation of the methodology, and benchmarking. Most important, a bundled approach can lead to sustained infection reduction.

Predictors of hospitalized patients' intentions to prevent healthcare harm: a cross sectional survey

BACKGROUND

Patients can play an important role in reducing healthcare harm but little is known about the factors that may affect patients' willingness to participate. In order to encourage the 'active' patient it is critical that we gain a deeper understanding of the antecedents of safety-relevant behaviours. Doing this will enable the implementation of effective interventions aimed at supporting patients to work with healthcare professionals in ensuring safe care.

OBJECTIVE

To examine predictors of patients' intentions to engage in two safety behaviours: (1) reminding healthcare staff to wash their hands and; (2) notifying healthcare staff if they are not wearing a hospital identification bracelet.

DESIGN

Cross-sectional survey study.

PARTICIPANTS

A purposive sampling method was employed to recruit 80 medical and surgical hospital inpatients aged 18-80 (mean 48) from one inner city London teaching hospital.

METHODS

A 42 item survey that measured the extent that patients' control beliefs, behavioural beliefs, normative beliefs and perceived susceptibility and severity towards a hospital-acquired infection or a misidentification error could predict their intentions to ask doctors/nurses about their hand washing compliance or notify doctors/nurses if they are not wearing a hospital identification bracelet. Data was analysed using multiple regression analysis.

RESULTS

Control beliefs, normative beliefs and perceived severity were the strongest predictors of patients' intentions to participate in both behaviours. The regression models accounted for a smaller percentage of the variance in patients' intentions to ask doctors/nurses if they have washed their hands (42%/37%) than notifying staff if they were not wearing an identification bracelet (54%/56%).

CONCLUSIONS

If patients understand why a behaviour is beneficial, they perceive it as acceptable to participate in and that they have control over the decision to engage in the behaviour, we hypothesise that more patients will intend to participate in that behaviour. When designing interventions aimed at encouraging the participation of patients in promoting their own safety, consideration should be given to the potential influence of patients' control beliefs, normative beliefs and perceived severity of errors on their intentions to participate.

Metrics and management: Two unresolved problems on the pathway to health care-associated infection elimination

Surveillance and management of health care-associated infections (HAIs) has traditionally relied on analyses of outcome data to elucidate trends in HAI incidence, discover host or treatment risk factors, and facilitate comparisons of HAI rates within and among licensed providers or facilities. This paper explores residual gaps and shortcomings associated with outcome reporting and possible sources of bias that may invalidate intra- and interfacility comparisons. As an alternative to outcome surveillance and reporting, real-time process monitoring and control is proposed. To address the need for uncompromising conformity with preventive measures, the concepts of social entropy, authority, responsibility, and accountability are explored and linked to process control at the bedside.

Reducing surgical nurses' aseptic practice-related stress

AIMS AND OBJECTIVES

This paper aims to explore aseptic practice-related stress in surgery. The objectives are to define stress-related factors and the means to reduce the stress.

BACKGROUND

Occupational stress is related to personal characteristics: job satisfaction and physiological and psychological well-being. The stress symptoms are often classified as part of a negative mood. Nurses have expressed stress when deadening their conscience to external demands with co-workers or internal working role-related demands. Surgery nurses expect fair division of work and compliance with rules. The hospital management, technology and the medical profession, instead of the needs of the patient, are recognised as a danger in the development of surgery nurses' role.

DESIGN

A qualitative stimulated recall interview was performed in the surgery of the university hospital.

METHODS

Thirty-one operations were videotaped, and 31 nurses interviewed during videotape stimulation. The 1306 text pages were transcripted and analysed by a qualitative membership categorisation device analysis.

RESULTS

The analysis revealed aseptic practice-related stress which constructed a sixteen level category. The membership categorisation identified connections between qualitatively attributed personnel and seven stress factors: working experience; time; equipment; person; patient; working morals and power. Final analysis revealed nurses reducing aseptic practice-related stress by safe, peaceful, competent and relative means.

CONCLUSIONS

The aseptic practice-related stress varied from positive motivating feelings to exhaustion. The stress was experienced by medical and nursing co-workers and reduced by means which varied according to expertise and co-workers.

RELEVANCE TO CLINICAL PRACTICE

This study showed needs for both the shared multiprofessional documentation of aseptic practice and better adherence to recommendations. Constructive means are useful when solving conflicts and replacing person-related aseptic practice with evidence-based. They may support nurses' professional growth, reduce their stress and increase the surgical patient's safety.

Impact of a multi-faceted training intervention on the improvement of hand hygiene and gloving practices in four healthcare settings including nursing homes, acute-care geriatric wards and physical rehabilitation units

AIMS

To assess the impact of a multi-faceted training program on the compliance with hand hygiene and gloving practices.

BACKGROUND

Hand hygiene is considered as the cornerstone of the prevention of hospital-acquired infections. Several studies have enhanced the poor effectiveness of training programs in improving hand hygiene compliance.

DESIGN

A before-after evaluation study.

METHODS

The study was conducted in four healthcare settings before and after an intervention program which included the performance feedback of the first evaluation phase, three six-h training sessions, the assessment of hand hygiene performance with teaching boxes and the organisation of one full-day session devoted to institutional communication around hand hygiene in each setting. Hand hygiene compliance and quality of hand rubbing were evaluated. Hand hygiene opportunities were differentiated into extra-series opportunities (before or after a single contact and before the first contact or after the last contact of a series of consecutive contacts) and intra-series opportunities (from the opportunity following the first contact to the opportunity preceding the last in the same series).

RESULTS

Overall, 969 contacts corresponding to 1,470 hand hygiene opportunities (760 during the first phase and 710 during the second) were observed. A significant improvement of observed practices was recorded for the hand hygiene compliance in intra-series opportunities (39·0% vs. 19·0%; p < 10(-5) ), the proportion of gloves worn if indicated (71·4% vs. 52·0%; p < 0·001) and the quality of hand rubbing (85·0% vs. 71·9%; p < 10(-5) ).

CONCLUSIONS

Some of the performances measured for both hand hygiene and gloving practices were improved. We plan to extend this investigation by performing a qualitative study with experts in behavioural sciences to try improving practices for which adherence was still weak after the training program such as hand hygiene in intra-series opportunities.

RELEVANCE TO CLINICAL PRACTICE

This study underscored the usefulness of implementing contextualised training programs, while more traditional courses have shown little impact.

Evaluating the impact of a hand hygiene campaign on improving adherence

We monitored compliance with hand hygiene (HH) by direct observation in 3 hospitals in Cantabria, Spain before and after implementation of an HH informational campaign, separately analyzing the effect of a training program. We report that training plus an informational campaign doubled the probability of HH, whereas the informational campaign without training decreased adherence, acting as a deleterious factor in HH adherence.

Hand disinfectant practice: the impact of an education intervention

The primary hypothesis of this study was that a lecture on basic hygiene routines could be associated with an increase in the use of disinfectant for hand hygiene. A secondary hypothesis was that the lecture could positively affect the staff's knowledge of and attitudes toward basic hygiene routines.A quasi-experimental design including one ward of the department of orthopedics in a Swedish university hospital was adopted.During the pre-intervention test period the consumption of hand disinfectant was measured for 30 days and a questionnaire was distributed to all staff. The hospital hygiene nurse subsequently provided a lecture on basic hygiene routines to all employees on the ward. During the post-intervention test period the hand disinfectant consumption was measured for another 30 days, and the questionnaire was distributed once again. A follow-up measurement was performed 9 months after the intervention.After the lecture on hygiene routines, the consumption of hand disinfectant increased by 93%. Nine months after the intervention, the consumption was still 21% higher than before the intervention. The result of the questionnaire showed that the employees considered themselves applying the disinfectant more thoroughly after the intervention. Some employees changed their perspective on basic hygiene routines after the lecture and stopped using watches and private clothes at work.Our findings suggest that a single education session, a hygiene lecture, could be a simple and cost-effective method to increase the use of hand disinfectant, thereby reducing the number of nosocomial infections on the wards.

[Hand hygiene: experience in two Spanish autonomous regions]

BACKGROUND AND OBJECTIVE

The Spanish Ministry of Health in accordance with WHO guidelines, promotes hand washing in hospitals, with the objective of reinforcing the commitment of health care workers to hand washing. In this study we described the results of the actions implemented in two communities, which were aimed at increasing hand-washing compliance among health care workers by means of a multimodal improvement programme.

MATERIAL AND METHOD

SETTING

Cantabrian and Murcian health services. The project was carried out in three phases. Phase I: analysis of preimplantation situation by means of an observational study in open care units, and a cross study of self-perceived compliance to hand hygiene with a questionnaire. Phase II: Implementing of training plan and promoting the use of alcohol-based solutions. Phase III: Reassessment of the results achieved by means of a post- intervention observational study.

RESULTS

There has been a significant increase in frequency of hand washing adherence in both communities. 40.5% 95% CI [38.2-42.4] vs. 46.2% 95% CI [44.0-48.4] (p < .001) in Cantabria, and 43% vs. 54% in Murcia.

CONCLUSIONS

The need to implement recommendations must continue to be emphasized and new interventions developed to increase health workers compliance, as well as promote educational policies and ease of access to alcohol-based solutions.

Nurses and physicians' perceptions of the importance and impact of healthcare-associated infections and hand hygiene: a multi-center exploratory study in Hong Kong

BACKGROUND

Hand hygiene promotion for patient safety is a challenge worldwide, and local data are critical to tailor strategies to the setting.

METHODS

This is a cross-sectional study of nurses and physicians providing direct patient care in four hospitals in Hong Kong using an anonymous questionnaire survey. Cognitive factors related to hand hygiene and the perception of effective interventions promoting hand hygiene were assessed.

RESULTS

The overall response rate was 59.3%. Among respondents, 70% of the nurses and 49% of the physicians perceived that over 15% of patients would suffer from healthcare-associated infections. A total of 79% of the nurses and 68% of the physicians believed that more than 5% of patients would die as a result of healthcare-associated infection. A total of 60% of the nurses and 46% of the physicians acknowledged that over 75% of healthcare-associated infections could be prevented by optimal hand hygiene practices, although 36% of the nurses and 23% of the physicians claimed that six to ten hand cleansing times per hour would be necessary. Bivariate analysis showed significant differences between professionals in self-reported performance. A multivariate regression model revealed that perceived behavioral control and subjective norms were the most important factors associated with the nurses and physicians' self-reported hand hygiene performance. However when gender was taken into account among professionals, subjective norms was the only consistent one.

CONCLUSION

These results could be used as a tool to create goal-specific strategies for motivating hand hygiene amongst nurses and physicians in Hong Kong, with appropriate promotional interventions delivered to the different professional groups and specialties.

What infection control measures will people carry out to reduce transmission of pandemic influenza? A focus group study

BACKGROUND

Pandemic influenza poses a future health threat against which infection control behaviours may be an important defence. However, there is little qualitative research examining perceptions of infection control measures in the context of pandemic influenza.

METHODS

Eight focus groups and one interview were conducted with a purposive sample of 31 participants. Participants were invited to discuss their perceptions of infection transmission and likely adherence to infection control measures in both non-pandemic and pandemic contexts. Infection control measures discussed included handwashing, social distancing and cough hygiene (e.g. covering mouth, disposing of tissues immediately etc.).

RESULTS

Thematic analysis revealed that although participants were knowledgeable about infection transmission, most expressed unfavourable attitudes toward control behaviours in non-pandemic situations. However, with the provision of adequate education about control measures and appropriate practical support (e.g. memory aids, access to facilities), most individuals report that they are likely to adhere to infection control protocols in the event of a pandemic. Of the behaviours likely to influence infection transmission, handwashing was regarded by our participants as more feasible than cough and sneeze hygiene and more acceptable than social distancing.

CONCLUSION

Handwashing could prove a useful target for health promotion, but interventions to promote infection control may need to address a number of factors identified within this study as potential barriers to carrying out infection control behaviours.

Psychological processes underlying nurses' handwashing behaviour

im/Background: Psychological models of behaviour A change have been found to be useful in predicting health-related behaviour in patients but have rarely been used in relation to the health behaviour of staff. This study explored the association between a range of psychological variables and self-reported handwashing in a sample of nurses who work in a large general hospital.

Method: A questionnaire-based cross-sectional, cor-relational study was used. Questionnaires examining demographics, self-efficacy, perceived importance of handwashing, perception of risk, occupational stress and training related to handwashing were administered to an opportunity sample ( n = 76) of nurses drawn from an acute hospital. ANOVAs, correlation and regression analyses were performed to determine significant covariates of handwashing behaviour.

Findings: There was a weak relationship between demographic variables and self-reported handwashing. The degree to which employees perceived their workplace to assist handwashing and the perceived importance of handwashing were related to self-reported handwashing. Accordingly further covariates of these variables were sought. Training received and occupational stress both covaried with nurses' perceptions of the degree to which their workplace assisted handwashing. Nurses' beliefs regarding the transmission of infections covaried with perceived importance of handwashing.

Conclusion: Occupational stress was observed to reduce the perception of having a supportive employer: organisations need to facilitate handwashing and protect staff from factors that have a detrimental impact, such as work-related stress. Nurses' perceived importance of the potential for poor handwashing practice to contribute to the transmission of infections should be highlighted in interventions.

Hand hygiene compliance by physicians: marked heterogeneity due to local culture?

BACKGROUND

Physician compliance with hand hygiene guidelines often has been reported as insufficient.

METHODS

The study was conducted in 2 hospitals (Hadassah Ein Kerem [EK] and Mt Scopus [MS]) in Jerusalem, Israel. Covert observations were conducted during morning rounds by trained observers. The data were recorded as the percentage of times that hand hygiene was applied out of the total contacts with patients. After the observational step, an intervention-providing an alcohol gel and encouraging its use-was instituted in several wards.

RESULTS

Physicians' compliance with hand hygiene averaged 77% at MS and 33% at EK (P < .001), and was characterized by a marked additional heterogeneity among wards. Rates of adherence ranged from as low as 4% in a gynecology ward to as high as 96% in a neonatal unit. Availability of a handwashing basin in the room and seniority status of the physician were associated with higher compliance rates but explained only a small part of the variation. Compliance improved significantly in 2 wards exposed to the intervention.

CONCLUSION

The remarkable heterogeneity in physicians' hand hygiene compliance among sites within the same institution is consistent with an important role of the local ward culture.

Hand hygiene adherence is influenced by the behavior of role models

OBJECTIVE

Proper hand hygiene (HH) reduces nosocomial infections. Therefore, factors that influence HH behavior of healthcare workers are of great interest. We hypothesized that strict HH adherence by supervisor role models would improve the HH behavior of junior staff.

DESIGN

Prospective observational study.

SETTING

Pediatric and cardiac intensive care units of a tertiary care children's hospital.

SUBJECTS

Two critical care fellows and four nurse orientees.

INTERVENTIONS

First, we observed and recorded HH adherence of the fellows and nurse orientees and their respective supervising attending physician or nurse preceptor during daily patient care. Subsequently, we paired the same fellows and nurse orientees with a different supervisor who maintained strict HH adherence, and again noted HH adherence. We used measures of HH opportunities and HH adherence consistent with guidelines set by the Centers for Disease Control and Prevention and Association for Professionals in Infection Control and Epidemiology.

MEASUREMENTS AND MAIN RESULTS

HH adherence by fellows and nurse orientees at baseline was 22% of 200 HH opportunities, and improved to 56% of 234 opportunities as a result of role modeling--an average increase of 34% points (95% confidence interval, 18.7-51; p < 0.01 by linear regression), representing a HH adherence rate greater than 1.5 times that of the baseline. The control senior practitioners' HH adherence rate was 20% of 180 opportunities compared with the study senior practitioners' HH adherence of 94% of 187 opportunities--an average difference of 72% points higher compared with the control senior practitioners (95% confidence interval, 56-88.3; p < 0.01 by linear regression).

CONCLUSIONS

HH adherence of junior practitioners improved under the supervision of adherent role models. These results suggest that HH behavior of senior practitioners plays a crucial influence on other staff. Senior healthcare practitioners should consider the important role they may play in reinforcing or weakening a culture of patient safety and proper HH.

[Impact of an educational intervention for promoting handwashing and the rational use of gloves in a hospital]

OBJECTIVE

To estimate the impact of educational intervention on hand washing and gloves use.

MATERIAL AND METHODS

The educational intervention consisted of a one-hour weekly workshop aimed at doctors and nurses, with a previous questionnaire on hand-washing, a presentation talk on three key points (hand washing, use of gloves, alcohol-based solutions). Adherence to hand washing and use of gloves was re-evaluated 6-9 months after the intervention.

RESULTS

We conducted 34 workshops for 296 health care workers, 239 (80.4%) women and 57 (19.6%) men, with an average age of 40.1 years (range, 18-62 years). Most were nurses (41.2%), nursing assistants (37.8%) and physicians (8.2%). Compliance to hand washing ranged between 29% and 87%. The gloves were used in maneuvers not indicated (19% before giving meals and a 27.7% when performing an ECG). Compliance with hand washing 6-9 months after the workshop improved significantly (p < 0.05) in three of the 5 items. The use of gloves was not significantly different. The intensity of the intervention was inversely related to the incidence of nosocomial infections (RR for every 100 workers intervened in the previous month = 0.89; 95% CI, 0.789-1.003; p = 0.057).

CONCLUSIONS

The training workshops had a positive impact on hand washing compliance, but there was no significant change in the use of gloves. The introduction of education has an inverse relationship to the incidence of nosocomial infections.

Avaliação da técnica de lavagem das mãos executada por alunos do Curso de Graduação em Enfermagem

O objetivo deste estudo foi comparar a execução e verificar a adesão à técnica de lavagem das mãos por alunos de um Curso de Graduação em Enfermagem. A pesquisa foi realizada com 113 alunos que estavam cumprindo estágio em instituições de saúde do município de São Paulo. Os dados foram coletados por observação direta utilizando um instrumento em forma de check-list com os passos da técnica. Os alunos do 2º e 3º ano obtiveram melhor desempenho na maioria dos passos na execução da técnica, com diferença estatisticamente significante, quando comparados ao 4º ano. A adesão aos passos da técnica pelos alunos foi muito baixa, pois apresentaram adesão menor que 50% em metade dos passos. A média de alunos que executou todos os passos da técnica corretamente foi muito baixa, 8,8%. Os alunos observados não realizaram a técnica de lavagem das mãos conforme recomendado.
