Dynamics of bacterial hand contamination during routine neonatal care

An observational study of the hand hygiene initiative: a comparison of preintervention and postintervention outcomes

OBJECTIVES

To evaluate the impact of implementing a simple, user-friendly eLearning module on hand hygiene (HH) compliance and infection rates.

DESIGN

Preintervention and postintervention observational study.

PARTICIPANTS

All neonates admitted to the neonatal intensive care unit (NICU) over the study period were eligible for participation and were included in the analyses. A total of 3422 patients were admitted over a 36-month span (July 2009 to June 2012).

INTERVENTIONS

In the preintervention and postintervention periods (phases I and II), all healthcare providers were trained on HH practices using an eLearning module. The principles of the '4 moments of HH' and definition of 'baby space' were incorporated using interactive tools. The intervention then extended into a long-term sustainability programme (phase III), including the requirement of an annual recertification of the module and introduction of posters and screensavers throughout the NICU.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome was HH compliance rates among healthcare providers in the three phases. The secondary outcome was healthcare-associated infection rates in the NICU.

RESULTS

HH compliance rates declined initially in phase II then improved in phase III with the addition of a long-term sustainability programme (76%, 67% and 76% in phases I, II and III, respectively (p<0.01). Infection rates showed an opposing, but concomitant trend in the overall population as well as in infants <1500 g and were 4%, 6% and 4% (p=0.02), and 11%, 21% and 16% (p<0.01), respectively, during the three phases.

CONCLUSIONS

Interventions to improve HH compliance are challenging to implement and sustain with the need for ongoing reinforcement and education.

Observance of hand washing procedures performed by the medical personnel after the patient contact. Part II

OBJECTIVES

The Centers for Disease Control and Prevention (CDC) as well as the World Health Organization (WHO) state that adequate hand hygiene maintained by medical personnel is an indispensable prerequisite for controlling nosocomial infections. The recommendations of CDC and WHO emphasize the obligation to wash hands after each contact with a patient, after the exposure to a potentially infectious material or upon the contact with objects surrounding the patient.

MATERIALS AND METHODS

The study was performed by quasi-observation among the group of 188 medical staff members (nurses and physicians) working in three selected hospitals of the Łódź Province. The procedure of hand washing/disinfection performed directly after the patient contact according to the recommendations of CDC and WHO was observed. The results were subject to statistical analysis (p < 0.05).

RESULTS

During 1544 h of observations, 4101 activities requiring hand washing were recorded. The medical personnel followed the hand hygiene procedures after the patient contact in 26.4% of the situations that require hygiene according to the guidelines. The level of observance of the hand washing procedures depended significantly on the type of performed activity, profession, degree of workload, index of activity, and time of duty hours. The mean time of hand washing after patient contact was 9.2 s for physicians and 6.7 s for nurses.

CONCLUSION

Both the level of observance of hygienic procedures after the contact with patients as well as the time of hand washing are insufficient. There is an urgent need to work out educational programs on maintaining proper hand hygiene for medical personnel.

Significant changes in the skin microbiome mediated by the sport of roller derby

Diverse bacterial communities live on and in human skin. These complex communities vary by skin location on the body, over time, between individuals, and between geographic regions. Culture-based studies have shown that human to human and human to surface contact mediates the dispersal of pathogens, yet little is currently known about the drivers of bacterial community assembly patterns on human skin. We hypothesized that participation in a sport involving skin to skin contact would result in detectable shifts in skin bacterial community composition. We conducted a study during a flat track roller derby tournament, and found that teammates shared distinct skin microbial communities before and after playing against another team, but that opposing teams’ bacterial communities converged during the course of a roller derby bout. Our results are consistent with the hypothesis that the human skin microbiome shifts in composition during activities involving human to human contact, and that contact sports provide an ideal setting in which to evaluate dispersal of microorganisms between people.

Hand hygiene after touching a patient's surroundings: the opportunities most commonly missed

BACKGROUND

Healthcare workers generally underestimate the role of environmental surfaces in the transmission of infection, and compliance with hand hygiene following contact with the environment is generally lower than following direct patient contact. To reduce the risk of onward transmission, healthcare workers must identify the need to wash hands with specific tasks or events.

AIM

To observe the movement of staff in critical care and general wards and determine the routes most commonly travelled and the surfaces most frequently touched with and without appropriate hand hygiene.

METHODS

Fifty-eight 90 min sessions of unobtrusive observation were made in open bays and isolation rooms. Link analysis was used to record staff movement from one location to another as well as the frequency of motion. Hand-hygiene audits were conducted using the World Health Organization 'five moments for hand hygiene' observational tool.

FINDINGS

In critical care, the majority of movement occurred within the bed space. The bedside computer and equipment trolley were the surfaces most commonly touched, often immediately after patient contact. In the general ward, movement between bed spaces was more common and observed hand hygiene ranged from 25% to 33%. Regardless of ward type, observed hand-hygiene compliance when touching the patient immediately on entering an isolation room was less than 30%.

CONCLUSIONS

Healthcare workers must be made aware that bacterial spread can occur even during activities of perceived low risk. Education and intervention programmes should focus on the potential contamination of ward computers, case notes and door handles.

Antibiotic timing in neonates with suspected hospital-acquired infections

There exists general agreement within neonatology that antibiotics should be administered promptly to neonates with possible bacterial sepsis and meningitis. We initiated a series of quality improvement cycles designed to reduce delays in the initiation of antibiotic therapy to less than 2 hours when hospital-acquired infection (HAI) was suspected. All infants in this study were in neonatal intensive care (level II or III) who were started on antibiotics for a suspected HAI (defined as an infection that occurred 72 hours after admission to the NICU) were audited. Through a series of quality improvement cycles, we analyzed sources of delays in the initiation of antibiotic therapy from the time the order was written through administration. In subsequent cycles, we intervened to reduce delays through education, standardize the evaluation process, and develop an online ordering system that streamlined the workflow patterns in the nurseries and pharmacy. Using a prospective cohort design, we compared antibiotic delivery times after each process improvement cycle. Antibiotic delivery time was reduced from a median of 137.5 minutes to 75 minutes and variation of practice was reduced in terms of standard deviation and range (P < .001). The use of computerized physician order entry significantly improved the writing of STAT orders (P < .0001). A systematic analysis of workflow patterns and efficiencies, coupled with improvement cycles targeting delays and development of a computerized physician order entry system, allowed us to improve antibiotic delivery time in neonates with suspected HAI in an intensive care nursery system.

An outbreak of Klebsiella pneumoniae late-onset sepsis in a neonatal intensive care unit in Guatemala

BACKGROUND

Gram-negative bloodstream infections are an important cause of neonatal mortality. In October 2009, we investigated a Klebsiella spp outbreak in a neonatal intensive care unit in Guatemala.

METHODS

Probable cases were defined as a Klebsiella spp isolated from blood in neonates aged <28 days in the neonatal intensive care unit between October 1 and November 10, 2009; confirmed cases were identified as Klebsiella pneumoniae. Clinical data were abstracted from medical charts. K pneumoniae isolates were genotyped by pulsed-field gel electrophoresis (PFGE) and tested for antimicrobial susceptibility. Infection control practices were inspected.

RESULTS

There were 14 confirmed cases. The median age at onset of infection was 3 days (range, 2-8 days). Nine patients died (64%). K pneumoniae isolates were resistant to multiple antimicrobials. PFGE revealed 2 distinct clusters. Breaches in infection control procedures included inappropriate intravenous solution use and inadequate hand hygiene and contact precautions.

CONCLUSIONS

We report a K pneumoniae outbreak with high neonatal mortality in Guatemala. PFGE clustering suggested a common source possibly related to reuse of a single-use intravenous medication or solution. The risk for K pneumoniae bloodstream infections in neonates in low-resource settings where sharing of solutions is common needs to be emphasized.

The World Health Organization '5 moments of hand hygiene': the scientific foundation

The World Health Organization (WHO) launched the first Global Patient Safety Challenge in 2005 and introduced the '5 moments of hand hygiene' in 2009 in an attempt to reduce the burden of health care associated infections. Many NHS trusts in England adopted this model of hand hygiene, which prompts health care workers to clean their hands at five distinct stages of caring for the patient. Our review analyses the scientific foundation for the five moments of hand hygiene and explores the evidence, as referenced by WHO, to support these recommendations. We found no strong scientific support for this regime of hand hygiene as a means of reducing health care associated infections. Consensus-based guidelines based on weak scientific foundations should be assessed carefully to prevent shifting the clinical focus from more important issues and to direct limited resources more effectively. We recommend caution in the universal adoption of the WHO '5 moments of hand hygiene' by orthopaedic surgeons and other health care workers and emphasise the need for evidence-based principles when adopting hospital guidelines aimed at promoting excellence in clinical practice.

Outbreak of neonatal infection by an endemic clone of Serratia marcescens

INTRODUCTION

The outbreak occurred between February and June 2006 and included identification of the cases, analysis of medical records, cultures from environmental sources, resistance analyses and genotyping profile of Serratia marcescens.

METHODS

The cultures were composed of 13 blood isolates, 17 rectal and hand swabs and air sampling.

RESULTS

The data obtained by pulsed-field gel electrophoresis exhibited three strains that contaminated 24 patients. Systemic infection was the most common in neonates with lower weight, long periods of hospitalization, premature delivery and the use of mechanical ventilation.

CONCLUSIONS

This investigation revealed the multifactorial nature of the outbreak. An endemic clone of S. marcescens was detected.

Parents--why it is now legal to put your child's nappy in the dustbin

BACKGROUND

Notifiable diseases in England and Wales include cholera, plague, relapsing fever, smallpox, typhus and food poisoning. S 26(1) of the Public Health (Control of Disease) Act 1984 Part II made it a criminal offence to place material which is known to have been exposed to infection from a notifiable disease or one of a number of additional diseases, and which has not been disinfected, in a dustbin. One such potential infection risk that is often placed in dustbins is the disposable nappy, particularly from children who are suffering from gastroenteritis.

METHOD

A literature review was undertaken using PubMed on the relationship between nappies and the transmission of infectious disease.

RESULTS

The literature review did not reveal any evidence of notifiable disease transmission through discarded nappies in dustbins.

CONCLUSIONS

As a result of a recent review, Part II of the Public Health (Control of Disease) Act 1984 has now been replaced by Part IIA by virtue of the Health and Social Care Act 2008, and so s 26(1) no longer applies. This is both an evidence-based decision and more importantly, decriminalizes thousands of parents who decide to discard their baby's nappy in the dustbin.

A review of hand-washing techniques in primary care and community settings

AIM

This review seeks to identify the most effective hand-washing and hand-cleansing practice that could be used in primary care.

BACKGROUND

Healthcare associated infection is a major problem in the UK causing 5000 deaths every year. Current guidelines indicate expert opinion is the level of evidence for hand washing as an activity to reduce infection.

DESIGN

Systematic review.

METHOD

Publications on hand-washing, hand-cleansing studies, policy and practice-based documents were sought by searching several databases. Terms used included hand washing, hand cleansing, hand hygiene, hand decontamination, infection control and primary care.

RESULTS

Few articles described the hand-washing technique in detail and some publications simply referred to either the European and British Standards or the Centre for Disease Control statement on hand washing. Major discrepancies in hand position and water flow direction were found. Several methodological problems were also identified and few studies were undertaken in primary care.

CONCLUSION

This review has found a lack of evidence for hand-washing techniques being undertaken in practice today. Findings from hand-washing technique studies were inconclusive and methodological issues exist resulting in sparse reliable evidence. There is an urgent need to undertake methodologically sound studies of hand-washing techniques for use in the ever expanding scope of primary care practice.

RELEVANCE TO CLINICAL PRACTICE

Evidence for hand-washing and hand-cleansing techniques will inform healthcare professional practice, and contribute to the overall management of infection control in primary care.

Prevention and control of health care-associated infections through improved hand hygiene

Determined actions are required to address the burden due to health care-associated infections worldwide and improve patient safety. Improving hand hygiene among health care workers is an essential intervention to achieve these goals. The World Health Organization (WHO) First Global Patient Safety Challenge, Clean Care is Safer Care, pledged to tackle the problem of health care-associated infection at its launch in 2005 and has elaborated a comprehensive set of guidelines for use in both developed and developing countries worldwide. The final version of the WHO Guidelines on Hand Hygiene in Health Care was issued in March 2009 and includes recommendations on indications, techniques, and products for hand hygiene. In this review, we discuss the role of hands in the transmission of health care-associated infection, the benefits of improved compliance with hand hygiene, and the recommendations, implementation strategies and tools recommended by WHO. We also stress the need for action to increase the pace with which these recommendations are implemented in facilities across India.

Recently tested strategies to reduce nosocomial infections in the neonatal intensive care unit

Recent years have witnessed a renewed interest in reducing hospital-acquired infections in critically ill patients. We review three recently tested strategies to decrease nosocomial infections specifically in the neonatal intensive care unit. These include improvement of hand hygiene, the incorporation of hand-hygiene practices into broader care bundles, and the prophylactic administration of antimicrobials, especially fluconazole, to infants at high risk prior to the onset of infection. The effectiveness of the first two interventions is well supported, particularly in older patient populations, while the effectiveness of the third is counterbalanced by the threat of the emergence of resistant-organism infections.

The World Health Organization Guidelines on Hand Hygiene in Health Care and their consensus recommendations

The World Health Organization's Guidelines on Hand Hygiene in Health Care have been issued by WHO Patient Safety on 5 May 2009 on the occasion of the launch of the Save Lives: Clean Your Hands initiative. The Guidelines represent the contribution of more than 100 international experts and provide a comprehensive overview of essential aspects of hand hygiene in health care, evidence- and consensus-based recommendations, and lessons learned from testing their Advanced Draft and related implementation tools.

Microbiological efficacy and tolerability of a new, non-alcohol-based hand disinfectant

OBJECTIVE

Alcohol-based hand disinfectants are widely used in hospitals. Occasionally, there is a need for non-alcohol-based products, but alternatives have been scarce. We studied the microbiological efficacy and tolerability of a water-based hand disinfectant for healthcare workers.

DESIGN

A water-based hand disinfectant was introduced as the only hand disinfectant in 5 wards in Turku University Hospital, Finland. Ninety-nine healthcare workers participated in fingerprint sampling during the 7-week study period. In another ward, 26 healthcare workers who were using alcohol-based hand disinfectant acted as control subjects for the skin reaction studies. The water-based product was tested in the laboratory according to the European standard EN 12791. We obtained 292 fingerprint samples before disinfection and 302 after disinfection. The opinions of healthcare workers were collected by use of a questionnaire, and skin reactions were assessed subjectively by use of questionnaires and objectively by measuring moisture and transepidermal water loss.

RESULTS

When tested in accordance with the European standard, the product met the requirements for short-term and long-term efficacy. The results of the fingerprint test showed that there was a statistically significant decrease in colonization of the fingertips before and after disinfection (P<.001). The users of the water-based hand disinfectant reported dry skin more often than did control subjects, but visual inspection and the results of the moisture measurement showed no difference between the users of the water-based hand disinfectant and the control subjects. Transepidermal water loss measurement also showed no deterioration of skin condition.

CONCLUSIONS

The water-based hand disinfectant was shown to be an effective hand disinfectant that caused relatively little skin irritation and can serve as a hand hygiene alternative in situations in which alcohol-based disinfectant cannot be used.

Contamination of portable radiograph equipment with resistant bacteria in the ICU

BACKGROUND

Approximately 15% of nosocomial infections in the ICU result from spread of bacteria on caregivers' hands. The routine chest radiograph provides an unexamined opportunity for bacterial spread: close contact with each patient and sequential examination of ICU patients. This study examined infection control procedures performed during routine chest radiographs, assessed whether resistant bacteria were transferred to the radiograph machine, and determined whether improved infection control practices by radiograph technicians could reduce bacterial transfer.

METHODS

Radiograph technicians were observed performing chest radiographs on all ICU patients. Culture specimens were taken from the radiograph machine. An educational intervention directed at technicians was instituted, and its effect on infection control and machine contamination was measured.

RESULTS

Surveillance of 173, 113, and 120 chest radiographs during observation, intervention, and follow-up periods was performed. Adequate infection control was practiced during the performance of 2 of 173 observation period radiographs (1%), 48 of 113 intervention period radiographs (42%; p < 0.001), and 12 of 120 follow-up period radiographs (10%; (p < 0.001) [follow-up vs intervention and observation periods]. Radiograph machine surface culture samples yielded resistant Gram-negative bacteria on 12 of 30 occasions (39%), 0 of 29 occasions, and 7 of 14 occasions (50%), respectively, for the observation, intervention, and follow-up periods (p < 0.001).

CONCLUSION

Multiresistant bacteria are frequently transferred from patients to the radiograph machine in the presence of poor infection control practices, and may be a source of cross-infection/colonization. Improved infection control practices decrease the occurrence of resistant organisms on the radiograph equipment. Radiograph technicians should be included in efforts to improve infection control measures.

Development of a method to measure bacterial transfer from hands

A method was developed to investigate the transfer of bacteria from the hands of healthcare workers (HCWs). The method involved standardised hand contact between the HCW and a recipient wearing sterile gloves, followed by sampling of the bare hands of the HCW and the gloved hands of the recipient by the glove juice method. The duration of contact, degree of friction and dryness of the hands could be varied. We investigated the applicability of the method for measuring transfer from hands artificially contaminated with Escherichia coli as well as from naturally contaminated hands following a 30s contact time with moderate friction and dry hands. Only a small proportion of bacteria on donor hands was recovered from the recipient: 0.15% for E. coli and 0.07% for natural hand flora. A smaller proportion of E. coli was recovered from bare skin compared with gloves, suggesting reduced survival of bacteria as a result of contact with natural skin. We suggest that these data are clinically relevant, and may indicate low transfer of bacteria during short contact with dry hands. This method is suitable to investigate the effect of potential risk factors for ineffective hand hygiene and the effect of hand hygiene procedures on contact transmission in clinical studies with large numbers of HCWs.

‘My five moments for hand hygiene’: a user-centred design approach to understand, train, monitor and report hand hygiene

Hand hygiene is a core element of patient safety for the prevention of healthcare-associated infections and the spread of antimicrobial resistance. Its promotion represents a challenge that requires a multi-modal strategy using a clear, robust and simple conceptual framework. The World Health Organization First Global Patient Safety Challenge 'Clean Care is Safer Care' has expanded educational and promotional tools developed initially for the Swiss national hand hygiene campaign for worldwide use. Development methodology involved a user-centred design approach incorporating strategies of human factors engineering, cognitive behaviour science and elements of social marketing, followed by an iterative prototype test phase within the target population. This research resulted in a concept called 'My five moments for hand hygiene'. It describes the fundamental reference points for healthcare workers (HCWs) in a time-space framework and designates the moments when hand hygiene is required to effectively interrupt microbial transmission during the care sequence. The concept applies to a wide range of patient care activities and healthcare settings. It proposes a unified vision for trainers, observers and HCWs that should facilitate education, minimize inter-individual variation and resource use, and increase adherence. 'My five moments for hand hygiene' bridges the gap between scientific evidence and daily health practice and provides a solid basis to understand, teach, monitor and report hand hygiene practices.

Reduction of health care associated infection risk in neonates by successful hand hygiene promotion

OBJECTIVES

Hand hygiene promotion interventions rarely result in sustained improvement, and an assessment of their impact on individual infection risk has been lacking. We sought to measure the impact of hand hygiene promotion on health care worker compliance and health care-associated infection risk among neonates.

METHODS

We conducted an intervention study with a 9-month follow-up among all of the health care workers at the neonatal unit of the Children's Hospital, University of Geneva Hospitals, between March 2001 and February 2004. A multifaceted hand hygiene education program was introduced with compliance assessed during successive observational surveys. Health care-associated infections were prospectively monitored, and genotypic relatedness of bloodstream pathogens was assessed by pulsed-field gel electrophoresis. A comparison of observed hand hygiene compliance and infection rates before, during, and after the intervention was conducted.

RESULTS

A total of 5325 opportunities for hand hygiene were observed. Overall compliance improved gradually from 42% to 55% across study phases. This trend remained significant after adjustment for possible confounders and paralleled the measured increase in hand-rub consumption (from 66.6 to 89.2 L per 1000 patient-days). A 9-month follow-up survey showed sustained improvement in compliance (54%), notably with direct patient contact (49% at baseline vs 64% at follow-up). Improved compliance was independently associated with infection risk reduction among very low birth weight neonates. Bacteremia caused by clonally related pathogens markedly decreased after the intervention.

CONCLUSIONS

Hand hygiene promotion, guided by health care workers' perceptions, identification of the dynamics of bacterial contamination of health care workers' hands, and performance feedback, is effective in sustaining compliance improvement and is independently associated with infection risk reduction among high-risk neonates.

epic2: National evidence-based guidelines for preventing healthcare-associated infections in NHS hospitals in England

National evidence-based guidelines for preventing healthcare-associated infections (HCAI) in National Health Service (NHS) hospitals in England were commissioned by the Department of Health (DH) and developed during 1998-2000 by a nurse-led multi-professional team of researchers and specialist clinicians. Following extensive consultation, they were published in January 2001. These guidelines describe the precautions healthcare workers should take in three areas: standard principles for preventing HCAI, which include hospital environmental hygiene, hand hygiene, the use of personal protective equipment, and the safe use and disposal of sharps; preventing infections associated with the use of short-term indwelling urethral catheters; and preventing infections associated with central venous catheters. The evidence for these guidelines was identified by multiple systematic reviews of experimental and non-experimental research and expert opinion as reflected in systematically identified professional, national and international guidelines, which were formally assessed by a validated appraisal process. In 2003, we developed complementary national guidelines for preventing HCAI in primary and community care on behalf of the National Collaborating Centre for Nursing and Supportive Care (National Institute for Healthand Clinical Excellence). A cardinal feature of evidence-based guidelines is that they are subject to timely review in order that new research evidence and technological advances can be identified, appraised and, if shown to be effective in preventing HCAI, incorporated into amended guidelines. Periodically updating the evidence base and guideline recommendations is essential in order to maintain their validity and authority. Consequently, the DH commissioned a review of new evidence published following the last systematic reviews. We have now updated the evidence base for making infection prevention and control recommendations. A critical assessment of the updated evidence indicated that the original epic guidelines published in 2001 remain robust, relevant and appropriate but that adjustments need to be made to some guideline recommendations following a synopsis of the evidence underpinning the guidelines. These updated national guidelines (epic2) provide comprehensive recommendations for preventing HCAI in hospitals and other acute care settings based on the best currently available evidence. Because this is not always the best possible evidence, we have included a suggested agenda for further research in each section of the guidelines. National evidence-based guidelines are broad principles of best practice which need to be integrated into local practice guidelines. To monitor implementation, we have suggested key audit criteria for each section of recommendations. Clinically effective infection prevention and control practice is an essential feature of protecting patients. By incorporating these guidelines into routine daily clinical practice, patient safety can be enhanced and the risk of patients acquiring an infection during episodes of healthcare in NHS hospitals in England can be minimised.

Behavioural considerations for hand hygiene practices: the basic building blocks

Hand hygiene is considered to be the most effective measure to prevent microbial pathogen cross-transmission and healthcare-associated infections. In October 2005, the World Health Organization (WHO) World Alliance for Patient Safety launched the first Global Patient Safety Challenge 2005-2006, 'Clean Care is Safer Care', to tackle healthcare-associated infection on a large scale. Within the Challenge framework, international infection control experts and consultative taskforces met to develop new WHO Guidelines on Hand Hygiene in Healthcare. The taskforce was asked to explore aspects underlying hand hygiene behaviour that may influence its promotion among healthcare workers. The dynamics of behavioural change are complex and multi-faceted, but are of vital importance when designing a strategy to improve hand hygiene compliance. A reflection on challenges to be met and areas for future research are also proposed.

Evidence-based model for hand transmission during patient care and the role of improved practices

Hand cleansing is the primary action to reduce health-care-associated infection and cross-transmission of antimicrobial-resistant pathogens. Patient-to-patient transmission of pathogens via health-care workers' hands requires five sequential steps: (1) organisms are present on the patient's skin or have been shed onto fomites in the patient's immediate environment; (2) organisms must be transferred to health-care workers' hands; (3) organisms must be capable of surviving on health-care workers' hands for at least several minutes; (4) handwashing or hand antisepsis by the health-care worker must be inadequate or omitted entirely, or the agent used for hand hygiene inappropriate; and (5) the caregiver's contaminated hand(s) must come into direct contact with another patient or with a fomite in direct contact with the patient. We review the evidence supporting each of these steps and propose a dynamic model for hand hygiene research and education strategies, together with corresponding indications for hand hygiene during patient care.

Bacterial contamination of nonsterile disposable gloves before use

BACKGROUND

After Bacillus cereus recovery in opened boxes of disposable gloves, the bacteriological contamination of disposable nonsterile gloves kept stored in native packages was investigated prospectively.

METHODS

Thirty-six commercially available nonsterile nonpowdered disposable gloves made of latex, vinyl, or nitrile were cultured.

RESULTS

A large variety of spore-forming and non-spore-forming bacteria was recovered, including Bacillus cereus and Clostridium perfringens.

CONCLUSION

This finding must be taken into consideration for care involving gloves in very immunocompromised patients.

Attitudes and perceptions toward hand hygiene among healthcare workers caring for critically ill neonates

BACKGROUND

Infectious complications are frequent among critically ill neonates. Hand hygiene is the leading measure to prevent healthcare-associated infections, but poor compliance has been repeatedly documented, including in the neonatal setting. Hand hygiene promotion requires a complex approach that should consider personal factors affecting healthcare workers' attitudes.

OBJECTIVE

To identify beliefs and perceptions associated with intention to comply with hand hygiene among neonatal healthcare workers.

METHODS

An anonymous, self-administered questionnaire (74 items) based on the theory of planned behavior was distributed to 80 neonatal healthcare workers to assess intention to comply, attitude toward hand hygiene, behavioral and subjective norm perceptions, and perception of difficulty to comply. Variables were assessed using multi-item measures and answers to 7-point bipolar scales. All multi-item scales had satisfactory internal consistency (alpha > 0.7). Multivariate logistic regression identified independent perceptions or beliefs associated with a positive intention to comply.

RESULTS

The response rate was 76% (61 of 80). Of the 49 nurses and 12 physicians responding, 75% believed that they could improve their compliance with hand hygiene. Intention to comply was associated with perceived control over the difficulty to perform hand hygiene (OR, 3.12; CI95, 1.12 to 8.70; P = .030) and a positive perception of how superiors valued hand hygiene (OR, 2.89; CI95, 1.08 to 7.77; P = .035).

CONCLUSION

Our data highlight the importance of the opinions of superiors and a strong perceived controllability over the difficulty to perform hand hygiene as possible internal factors that may influence hand hygiene compliance.
