Compliance with routine use of gowns by healthcare workers (HCWs) and non-HCW visitors on entry into the rooms of patients under contact precautions

A survey of healthcare workers on the acceptance and value of personal protective equipment for patient care

OBJECTIVE

Assess healthcare workers' (HCW) attitudes toward universal masking, and gowns and gloves used as part of transmission-based precautions.

DESIGN

Cross-sectional survey.

SETTING

Academic, tertiary care medical center in Baltimore, Maryland.

PARTICIPANTS

HCW who work in patient care areas and have contact with patients.

METHODS

In May 2023, a 15-question web-based survey was distributed by the hospital's communications team via email. The survey contained questions to assess HCW perceptions of universal masking policies prior to the availability of COVID-19 vaccines and at the time of the survey, and the use of gowns and gloves for transmission-based precautions. Descriptive statistics were used to summarize data. Differences in agreement with universal masking over time, level of agreement with gown and glove policies, and with all PPE types across respondent characteristics were assessed.

RESULTS

257 eligible respondents completed the survey. Nurses and patient care technicians (43%) and providers (17%) were the most commonly reported roles. Agreement with universal mask use decreased from 84% early in the pandemic to 55% at the time of the survey. 70% and 72% of HCW agreed masks protect themselves and others, respectively. 63% expressed any level of annoyance with mask wearing, the most often due to communication challenges or physical discomfort. 75% agreed with gown use for antibiotic-resistant bacteria compared with 90% for glove use.

CONCLUSIONS

The majority of HCW agree with the use of PPE to prevent pathogen transmission in the healthcare setting. Agreement with universal mask use for patient care shifted during the COVID-19 pandemic.

Compliance with infection prevention and control standard precautions and factors associated with noncompliance among healthcare workers working in public hospitals in Addis Ababa, Ethiopia

BACKGROUND

Standard Precautions (SPs) are the minimal infection prevention and control (IPC) measures that apply to all patient care activities at all times, regardless of whether the patient has a suspected or proven disease, in any place where healthcare service is provided. These evidence-based practices protect healthcare workers (HCWs) from infection while preventing the spread of infectious agents among patients, visitors, and the environment.

OBJECTIVES

Assessed compliance of HCWs working in public hospitals in Addis Ababa to infection prevention and control SPs, and factors associated with noncompliance.

METHODS

In a hospital-based cross-sectional study, 422 HCWs were recruited from nine public hospitals in Addis Ababa using a stratified random sampling technique. Data were collected using self-administered questionnaires, entered into a computer using Epi data, and analyzed using SPSS version 25. The association between the independent and the outcome variables was investigated using logistic regression. Odd ratios with corresponding 95% confidence intervals (CI) were used as measures of the strength of the association between the outcome and the explanatory variables. A p-value below 5% was considered an indicator of statistical significance.

RESULTS

The level of knowledge of HCWs about IPC and SPs was 51.9% and 36.49% of the respondents were compliant with SPs. Receiving IPC Training [Adjusted Odds Ratio (AOR) = 1.81, 95% CI 1.06, 3.09], knowing SPs [AOR = 3.46, 95% CI = 1.83, 6.54], presence of a mechanism in the hospital to enforce the IPC practices [AOR = 1.71 95% CI = 1.01, 2.89], and availability of cleaning and disinfection chemicals in the hospital [AOR = 2.18, 95%CI = 1.15, 4.13] were significantly associated with the HCWs' compliance with SPs.

CONCLUSION

Compliance with IPC standard precautions of HCWs in public hospitals of Addis Ababa is suboptimal. Working in medical units, less work experience, lack of training, poor knowledge, absence of a mechanism to enforce adherence, and inadequate resources are independent predictors for non-compliance of the HCWs.

Deconstructing the effects of stochasticity on transmission of hospital-acquired infections in ICUs

The inherent stochasticity in transmission of hospital-acquired infections (HAIs) has complicated our understanding of transmission pathways. It is particularly difficult to detect the impact of changes in the environment on acquisition rate due to stochasticity. In this study, we investigated the impact of uncertainty (epistemic and aleatory) on nosocomial transmission of HAIs by evaluating the effects of stochasticity on the detectability of seasonality of admission prevalence. For doing so, we developed an agent-based model of an ICU and simulated the acquisition of HAIs considering the uncertainties in the behaviour of the healthcare workers (HCWs) and transmission of pathogens between patients, HCWs, and the environment. Our results show that stochasticity in HAI transmission weakens our ability to detect the effects of a change, such as seasonality patterns, on acquisition rate, particularly when transmission is a low-probability event. In addition, our findings demonstrate that data compilation can address this issue, while the amount of required data depends on the size of the said change and the degree of uncertainty. Our methodology can be used as a framework to assess the impact of interventions and provide decision-makers with insight about the minimum required size and target of interventions in a healthcare facility.

Effectiveness of Video-Based Online Training for Health Care Workers to Prevent COVID-19 Infection: An Experience at a Tertiary Care Level Institute, Uttarakhand, India

Purpose Amidst the current COVID-19 pandemic, traditional teaching methodology took a back foot. However, an urgent need for training health care worker (HCW) on preventive measures for COVID-19 infection was the need of the hour. Keeping in mind the precautionary measures required to combat COVID-19 infection, the only promising option for training was by adopting an online learning method. This study was undertaken to determine the effectiveness of video-based training using online platforms for infection prevention and control (IPC) training during the COVID-19 pandemic. Methods A quasi-experimental study, with only one experimental group comprising of HCWs, was undertaken to assess the effect of intervention which included video-assisted teaching-learning regarding IPC measures with a special focus on COVID-19 at a tertiary care Institute in North India. Online sessions were conducted on Do's and Don'ts, Hand Hygiene, donning and doffing of personal protective equipment (PPE), cleaning and disinfection, and bio-medical waste (BMW) management with the help of pre-recorded videos which was pre-validated. The session was followed by online interaction with participants by a single resource person. Pre-test and post-test were conducted through google forms before commencement and at the end of the online session respectively. The data were analyzed in terms of descriptive frequencies and percentages of different domains to describe the pre- and post-test knowledge. Results A total of 576 participants were included in the study. There was a statistically significant gain in scores of all questions related to cleaning and disinfection; and BMW. No significant change was observed in knowledge regarding the sequence of doffing (p-value: 0.94). The result of pairwise comparisons pre-test and post-test scores showed that intervention through video-assisted teaching-learning resulted in improvement of knowledge which was found to be statistically significant (p-value < 0.001). Conclusion Video-assisted teaching-learning through virtual platforms effectively trained health personnel on infection prevention and control practices during the COVID-19 pandemic. Video-assisted training can successfully be handled by a single resource person to impart the knowledge and skill to the trainee. Virtual teaching and learning is a feasible and efficient method to deliver training to HCWs on infection control practices and this methodology may be adopted in the future for several other training in manpower crunch situations, similar restrictive circumstances as posed by the COVID-19 pandemic.

Are Stethoscopes, Coats, and Pagers Potential Sources of Healthcare Associated Infections?

We conducted a study to determine the rate of bacterial colonization of stethoscopes, coats, and pagers of residents at a pediatric residency training program as compared to that of badges, sleeves, and pagers of non-patient care staff (control group). Among 213 cultures obtained from 71 residents, 27 potential pathogens were isolated from 22 residents (27/213, 12.7%) as compared to 10 potential pathogens out of 162 samples obtained from 54 control participants (10/162, 6.2%) (P = .0375). The most common pathogen isolated from residents and control participants was methicillin sensitive Staphylococcus aureus (MSSA). The source of positive cultures among the residents was the stethoscope (8/22, 36.3%), pager (8/22, 36.3%), and coat sleeve (11/22, 50%). The rates of colonization with potential pathogens were higher among residents than control participants and about 12% of residents’ stethoscopes, coats and pagers were colonized with bacterial pathogens. These are potential sources of nosocomial transmission of pathogenic organisms.

Evaluation of the Cost-effectiveness of Infection Control Strategies to Reduce Hospital-Onset Clostridioides difficile Infection

Importance

Clostridioides difficile infection is the most common hospital-acquired infection in the United States, yet few studies have evaluated the cost-effectiveness of infection control initiatives targeting C difficile.

Objective

To compare the cost-effectiveness of 9 C difficile single intervention strategies and 8 multi-intervention bundles.

Design, Setting, and Participants

This economic evaluation was conducted in a simulated 200-bed tertiary, acute care, adult hospital. The study relied on clinical outcomes from a published agent-based simulation model of C difficile transmission. The model included 4 agent types (ie, patients, nurses, physicians, and visitors). Cost and utility estimates were derived from the literature.

Interventions

Daily sporicidal cleaning, terminal sporicidal cleaning, health care worker hand hygiene, patient hand hygiene, visitor hand hygiene, health care worker contact precautions, visitor contact precautions, C difficile screening at admission, and reduced intrahospital patient transfers.

Main Outcomes and Measures

Cost-effectiveness was evaluated from the hospital perspective and defined by 2 measures: cost per hospital-onset C difficile infection averted and cost per quality-adjusted life-year (QALY).

Results

In this agent-based model of a simulated 200-bed tertiary, acute care, adult hospital, 5 of 9 single intervention strategies were dominant, reducing cost, increasing QALYs, and averting hospital-onset C difficile infection compared with baseline standard hospital practices. They were daily cleaning (most cost-effective, saving $358 268 and 36.8 QALYs annually), health care worker hand hygiene, patient hand hygiene, terminal cleaning, and reducing intrahospital patient transfers. Screening at admission cost $1283/QALY, while health care worker contact precautions and visitor hand hygiene interventions cost $123 264/QALY and $5 730 987/QALY, respectively. Visitor contact precautions was dominated, with increased cost and decreased QALYs. Adding screening, health care worker hand hygiene, and patient hand hygiene sequentially to the daily cleaning intervention formed 2-pronged, 3-pronged, and 4-pronged multi-intervention bundles that cost an additional $29 616/QALY, $50 196/QALY, and $146 792/QALY, respectively.

Conclusions and Relevance

The findings of this study suggest that institutions should seek to streamline their infection control initiatives and prioritize a smaller number of highly cost-effective interventions. Daily sporicidal cleaning was among several cost-saving strategies that could be prioritized over minimally effective, costly strategies, such as visitor contact precautions.

A qualitative study of factors affecting personal protective equipment use among health care personnel

BACKGROUND

Health care personnel (HCP) use of personal protective equipment (PPE) reduces infectious disease transmission. However, PPE compliance remains low. The objective of this study was to better understand how HCP perceptions factor into PPE decision making as well as how organizational processes and the environment impact behavior.

METHODS

This qualitative study used observation and focus groups at 2 medical centers. Data were analyzed using thematic analysis.

RESULTS

The decision to use PPE and to follow precaution practices was influenced by risk perception as well as organizational and environmental factors. Perceived risk, related to certain organisms and work tasks, was considered by HCP when deciding to use PPE. Organizational processes, such as policies that were not applied uniformly, and environmental factors, such as clean versus contaminated space, also played a role in HCP PPE use.

DISCUSSION

Because HCP seemed focused on organisms and work tasks, education on specific organisms and helping HCP think through their workflow may be more effective in conveying the importance of PPE in reducing transmission. Additionally, isolation practices should be compared across disciplines to ensure they complement, rather than contradict, one another. Assessment of the environment may help protect HCP and patients from infectious organisms.

CONCLUSION

Preventing the spread of infectious organisms should not depend solely on PPE use, but should also be recognized as an organizational responsibility.

A comprehensive review of randomized clinical trials in three medical journals reveals 396 medical reversals

The ability to identify medical reversals and other low-value medical practices is an essential prerequisite for efforts to reduce spending on such practices. Through an analysis of more than 3000 randomized controlled trials (RCTs) published in three leading medical journals (the Journal of the American Medical Association, the Lancet, and the New England Journal of Medicine), we have identified 396 medical reversals. Most of the studies (92%) were conducted on populations in high-income counties, cardiovascular disease was the most common medical category (20%), and medication was the most common type of intervention (33%).

Background Information: Isolation Routines

The isolation of patients with suspected or documented infections—to not spread to others—has been discussed for hundreds of years. Guidelines are many, methods are different, attitudes show vide variations, routines and procedures are still changing, regulations by law may be absent, and some healthcare professionals may be afraid of adverse outcomes of isolation [1–44]. Microbes that are spread in the environment, on the hands and equipment are invisible. The invisible agent does not call on attention before the infection; clinical disease, hospital infection or nosocomial infection is a factum that can be registered [23, 28, 29, 35–37]. How to stop the transmission is often “to believe and not believe” in infection control.

Assessment of Environmental Contamination with Pathogenic Bacteria at a Hospital Laundry Facility

Little is known about exposure to pathogenic bacteria among industrial laundry workers who work with soiled clinical linen. To study worker exposures, an assessment of surface contamination was performed at an industrial laundry facility serving hospitals in Seattle, WA, USA. Surface swab samples (n = 240) from the environment were collected during four site visits at 3-month intervals. These samples were cultured for Clostridium difficile, methicillin-resistant Staphylococcus aureus (MRSA), and vancomycin-resistant enterococci (VRE). Voluntary participation of 23 employees consisted of nasal swabs for detection of MRSA, observations during work, and questionnaires. Contamination with all three pathogens was observed in both dirty (laundry handling prior to washing) and clean areas (subsequent to washing). The dirty area had higher odds of overall contamination (≥1 pathogen) than the clean area (odds ratio, OR = 18.0, 95% confidence interval 8.9-36.5, P < 0.001). The odds of contamination were high for each individual pathogen: C. difficile, OR = 15.5; MRSA, OR = 14.8; and VRE, OR = 12.6 (each, P < 0.001). The highest odds of finding surface contamination occurred in the primary and secondary sort areas where soiled linens were manually sorted by employees (OR = 63.0, P < 0.001). The study substantiates that the laundry facility environment can become contaminated by soiled linens. Workers who handle soiled linen may have a higher risk of exposure to C. difficile, MRSA, and VRE than those who handle clean linens. Improved protocols for prevention and reduction of environmental contamination were implemented because of this study.

Interventions to Reduce the Incidence of Hospital-Onset Clostridium difficile Infection: An Agent-Based Modeling Approach to Evaluate Clinical Effectiveness in Adult Acute Care Hospitals

Background

Despite intensified efforts to reduce hospital-onset Clostridium difficile infection (HO-CDI), its clinical and economic impacts continue to worsen. Many institutions have adopted bundled interventions that vary considerably in composition, strength of evidence, and effectiveness. Considerable gaps remain in our knowledge of intervention effectiveness and disease transmission, which hinders HO-CDI prevention.

Methods

We developed an agent-based model of C. difficile transmission in a 200-bed adult hospital using studies from the literature, supplemented with primary data collection. The model includes an environmental component and 4 distinct agent types: patients, visitors, nurses, and physicians. We used the model to evaluate the comparative clinical effectiveness of 9 single interventions and 8 multiple-intervention bundles at reducing HO-CDI and asymptomatic C. difficile colonization.

Results

Daily cleaning with sporicidal disinfectant and C. difficile screening at admission were the most effective single-intervention strategies, reducing HO-CDI by 68.9% and 35.7%, respectively (both P < .001). Combining these interventions into a 2-intervention bundle reduced HO-CDI by 82.3% and asymptomatic hospital-onset colonization by 90.6% (both, P < .001). Adding patient hand hygiene to healthcare worker hand hygiene reduced HO-CDI rates an additional 7.9%. Visitor hand hygiene and contact precaution interventions did not reduce HO-CDI, compared with baseline. Excluding those strategies, healthcare worker contact precautions were the least effective intervention at reducing hospital-onset colonization and infection.

Conclusions

Identifying and managing the vast hospital reservoir of asymptomatic C. difficile by screening and daily cleaning with sporicidal disinfectant are high-yield strategies. These findings provide much-needed data regarding which interventions to prioritize for optimal C. difficile control.

Adherence to contact precautions by different types of healthcare workers through video monitoring in a tertiary hospital

BACKGROUND

Contact precautions are required to prevent transmission of multi-drug-resistant organisms; however, reports on adherence rates vary. This study used video monitoring to evaluate adherence to the use of personal protective equipment (PPE) by different types of healthcare workers.

METHODS

This observational study was conducted in a 781-bed tertiary hospital from July 2016 to March 2017. Cameras were installed in areas where staff don PPE. Infection control teams observed the videos and assessed adherence rates.

RESULTS

In total, 1097 opportunities for donning PPE were observed. Most staff observed were nurses and nursing assistants (Ns/Nsas) (880/1097, 80.2%). Overall, the adherence rate to appropriate PPE use was 34.0%. The adherence rate among Ns/Nsas was lower (239/858, 27.9%) compared with infectious disease doctors (18/18, 100%) and cleaning staff (42/49, 85.7%). The adherence rate for PPE use for Clostridium difficile infection (CDI) with toxin detection was significantly higher than that for CDI without toxin detection and multi-drug-resistant organisms (P<0.001 for both). The adherence rate for patients with an independent functional status was higher than that for patients with a dependent functional status (P=0.018). The adherence rate was lower in the intensive care unit (ICU) than in non-ICU wards (27.6% vs 36.5%; P=0.006).

CONCLUSION

Video monitoring is a useful tool for monitoring adherence to PPE use, facilitating observation of more PPE opportunities than direct observation. Adherence to contact precautions varied by occupation; however, overall adherence was insufficient. The lower adherence rate in nurses might be due to more frequent care visits.

Isolation Precautions for Visitors to Healthcare Settings

Visitors may be involved in infection transmission within healthcare settings; however, there is currently limited published data on this subject. This chapter describes situations in which visitor-associated infection transmission occurred and highlights the potential role of visitors in the transmission of pathogenic organisms that can lead to outbreaks in healthcare settings. Infection prevention measures, including isolation precautions and visitor restriction, may be utilized and potentially adapted in order to protect patients and their visitors as well as healthcare personnel. The practical and ethical challenges regarding the use of isolation precautions among visitors to healthcare facilities are discussed.

Understanding the Impact of Interventions to Prevent Antimicrobial Resistant Infections in the Long-Term Care Facility: A Review and Practical Guide to Mathematical Modeling

OBJECTIVES (1) To systematically search for all dynamic mathematical models of infectious disease transmission in long-term care facilities (LTCFs); (2) to critically evaluate models of interventions against antimicrobial resistance (AMR) in this setting; and (3) to develop a checklist for hospital epidemiologists and policy makers by which to distinguish good quality models of AMR in LTCFs. METHODS The CINAHL, EMBASE, Global Health, MEDLINE, and Scopus databases were systematically searched for studies of dynamic mathematical models set in LTCFs. Models of interventions targeting methicillin-resistant Staphylococcus aureus in LTCFs were critically assessed. Using this analysis, we developed a checklist for good quality mathematical models of AMR in LTCFs. RESULTS AND DISCUSSION Overall, 18 papers described mathematical models that characterized the spread of infectious diseases in LTCFs, but no models of AMR in gram-negative bacteria in this setting were described. Future models of AMR in LTCFs require a more robust methodology (ie, formal model fitting to data and validation), greater transparency regarding model assumptions, setting-specific data, realistic and current setting-specific parameters, and inclusion of movement dynamics between LTCFs and hospitals. CONCLUSIONS Mathematical models of AMR in gram-negative bacteria in the LTCF setting, where these bacteria are increasingly becoming prevalent, are needed to help guide infection prevention and control. Improvements are required to develop outputs of sufficient quality to help guide interventions and policy in the future. We suggest a checklist of criteria to be used as a practical guide to determine whether a model is robust enough to test policy. Infect Control Hosp Epidemiol 2017;38:216-225.

Assessing patient and caregiver understanding of and satisfaction with the use of contact isolation

BACKGROUND

Contact isolation is a method used for limiting the spread of antimicrobial-resistant organisms when caring for patients. This policy has been linked to several adverse outcomes and less patient satisfaction. We assessed patient and caregiver understanding and satisfaction with the use of contact isolation.

METHODS

A prospective survey of >500 patients in contact isolation at our institution was performed during 2014. Participants responded to a series of statements relating to contact isolation, using a 5-point Likert scale. Responses were assessed for overall positivity or negativity and further compared according to floor type or designation.

RESULTS

Of the patients, 48.7% responded to the survey; 70 caregivers also responded. Patient and caregiver responses were similar and were positive overall. Most respondents felt safer because of the use of contact isolation and because it prevented infections. A smaller majority of respondents also thought the policy was adequately explained to them and adhered to by staff.

CONCLUSIONS

In the largest collection of respondents surveyed to date about contact isolation and its impact on them, the policy was viewed positively, both by patients and caregivers. There is still room for improvement in the area of patient education regarding the use of contact isolation.

Contact Precautions More Is Not Necessarily Better

Objective.

To determine whether increases in contact isolation precautions are associated with decreased adherence to isolation practices among healthcare workers (HCWs).

Design.

Prospective cohort study from February 2009 to October 2009.

Setting.

Eleven teaching hospitals.

Participants.

HCWs.

Methods.

One thousand thirteen observations conducted on HCWs. Additional data included the number of persons in isolation, types of HCWs, and hospital-specific contact precaution practices. Main outcome measures included compliance with individual components of contact isolation precautions (hand hygiene before and after patient encounter, donning of gown and glove upon entering a patient room, and doffing upon exiting) and overall compliance (all 5 measures together) during varying burdens of isolation.

Results.

Compliance with hand hygiene was as follows: prior to donning gowns/gloves, 37.2%; gowning, 74.3%; gloving, 80.1%; doffing of gowns/gloves, 80.1%; after gown/glove removal, 61%. Compliance with all components was 28.9%. As the burden of isolation increased (20% or less to greater than 60%), a decrease in compliance with hand hygiene (43.6%—4.9%) and with all 5 components (31.5%—6.5%) was observed. In multivariable analysis, there was an increase in noncompliance with all 5 components of the contact isolation precautions bundle (odds ratio [OR], 6.6 [95% confidence interval (CI), 1.15-37.44];P= .03) and in noncompliance with hand hygiene prior to donning gowns and gloves (OR, 10.1 [95% CI, 1.84—55.54];P= .008) associated with increasing burden of isolation.

Conclusions.

As the proportion of patients in contact isolation increases, compliance with contact isolation precautions decreases. Placing 40% of patients under contact precautions represents a tipping point for noncompliance with contact isolation precautions measures.

Isolation gowns in health care settings: Laboratory studies, regulations and standards, and potential barriers of gown selection and use

Although they play an important role in infection prevention and control, textile materials and personal protective equipment (PPE) used in health care settings are known to be one of the sources of cross-infection. Gowns are recommended to prevent transmission of infectious diseases in certain settings; however, laboratory and field studies have produced mixed results of their efficacy. PPE used in health care is regulated as either class I (low risk) or class II (intermediate risk) devices in the United States. Many organizations have published guidelines for the use of PPE, including isolation gowns, in health care settings. In addition, the Association for the Advancement of Medical Instrumentation published a guidance document on the selection of gowns and a classification standard on liquid barrier performance for both surgical and isolation gowns. However, there is currently no existing standard specific to isolation gowns that considers not only the barrier resistance but also a wide array of end user desired attributes. As a result, infection preventionists and purchasing agents face several difficulties in the selection process, and end users have limited or no information on the levels of protection provided by isolation gowns. Lack of knowledge about the performance of protective clothing used in health care became more apparent during the 2014 Ebola epidemic. This article reviews laboratory studies, regulations, guidelines and standards pertaining to isolation gowns, characterization problems, and other potential barriers of isolation gown selection and use.

Role of healthcare apparel and other healthcare textiles in the transmission of pathogens: a review of the literature

Healthcare workers (HCWs) wear uniforms, such as scrubs and lab coats, for several reasons: (1) to identify themselves as hospital personnel to their patients and employers; (2) to display professionalism; and (3) to provide barrier protection for street clothes from unexpected exposures during the work shift. A growing body of evidence suggests that HCWs' apparel is often contaminated with micro-organisms or pathogens that can cause infections or illnesses. While the majority of scrubs and lab coats are still made of the same traditional textiles used to make street clothes, new evidence suggests that current innovative textiles function as an engineering control, minimizing the acquisition, retention and transmission of infectious pathogens by reducing the levels of bioburden and microbial sustainability. This paper summarizes recent literature on the role of apparel worn in healthcare settings in the acquisition and transmission of healthcare-associated pathogens. It proposes solutions or technological interventions that can reduce the risk of transmission of micro-organisms that are associated with the healthcare environment. Healthcare apparel is the emerging frontier in epidemiologically important environmental surfaces.

Understanding the current state of infection prevention to prevent Clostridium difficile infection: a human factors and systems engineering approach

BACKGROUND

Achieving and sustaining high levels of health care worker (HCW) compliance with contact isolation precautions is challenging. The aim of this study was to determine HCW work system barriers to and facilitators of adherence to contact isolation for patients with suspected or confirmed Clostridium difficile infection (CDI) using a human factors and systems engineering approach.

METHODS

This prospective cohort study took place between September 2013 and November 2013 at a large academic medical center (hospital A) and an affiliated Veterans Administration hospital (hospital B). A human factors engineering (HFE) model for patient safety, the Systems Engineering Initiative for Patient Safety model, was used to guide work system analysis and direct observation data collection. There were 288 observations conducted. HCWs and visitors were assessed for compliance with all components of contact isolation precautions (hand hygiene, gowning, and gloving) before and after patient contact. Time required to complete contact isolation precautions was measured, and adequacy of contact isolation supplies was assessed.

RESULTS

Full compliance with contact isolation precautions was low at both hospitals A (7%) and B (22%). Lack of appropriate hand hygiene prior to room entry (compliance for hospital A: 18%; compliance for hospital B: 29%) was the most common reason for lack of full compliance. More time was required for full compliance compared with compliance with no components of contact isolation precautions before patient room entry, inside patient room, and after patient room exit (59.9 vs 3.2 seconds, P < .001; 507.3 vs 149.7 seconds, P = .006; 15.2 vs 1.3 seconds, P < .001, respectively). Compliance was lower when contact isolation supplies were inadequate (4% vs 16%, P = .005).

CONCLUSIONS

Adherence to contact isolation precautions for CDI is a complex, time-consuming process. HFE analysis indicates that multiple work system components serve as barriers and facilitators to full compliance with contact isolation precautions and should be addressed further to prevent CDI.

Knowledge, perceptions, and practices of methicillin-resistant Staphylococcus aureus transmission prevention among health care workers in acute-care settings

BACKGROUND

Health care workers (HCWs) play a critical role in prevention of health care-associated infections such as methicillin-resistant Staphylococcus aureus (MRSA), but glove and gown contact precautions and hand hygiene may not be consistently used with vulnerable patients.

METHODS

A cross-sectional survey of MRSA knowledge, attitudes/perceptions, and practices among 276 medical, nursing, allied health, and support services staff at an acute-care hospital in the eastern United States was completed in 2012. Additionally, blinded observations of hand hygiene behaviors of 104 HCWs were conducted.

RESULTS

HCWs strongly agreed that preventive behaviors reduce the spread of MRSA. The vast majority reported that they almost always engage in preventive practices, but observations of hand hygiene found lower rates of adherence among nearly all HCW groups. HCWs who reported greater comfort with telling others to take action to prevent MRSA transmission were significantly more likely to self-report adherence to recommended practices.

CONCLUSIONS

It is important to reduce barriers to adherence with preventive behaviors and to help all HCWs, including support staff who do not have direct patient care responsibilities, to translate knowledge about MRSA transmission prevention methods into consistent adherence of themselves and their coworkers to prevention guidelines.

Survey of North Carolina hospital policies regarding visitor use of personal protective equipment for entering the rooms of patients under isolation precautions

OBJECTIVE

To explore the range of hospital policies for visitor use of personal protective equipment (PPE) when entering the room of patients under isolation precautions.

DESIGN

Survey using an online questionnaire.

SETTING

Acute care hospitals registered in the North Carolina Statewide Program for Infection Control and Epidemiology (SPICE).

METHODS

A total of 136 North Carolina hospitals were invited to participate in an online survey. The survey questionnaire was developed, reviewed, and pilot tested, and then it was distributed through SPICE listserv registered e-mail addresses. The survey was conducted from February 6 to March 30, 2012.

RESULTS

Among 93 respondent hospitals (response rate, 68.4%), 82 acute care hospitals (60.3%) were included in the analyses. Substantial variation was observed with regard to hospital policies for visitor PPE use when visiting patients under isolation precautions. A total of 71% of hospitals had a hospital visitor policy, and 96% of respondents agreed that hospitals should have a visitor policy. Only 14% of hospitals monitored visitor compliance with PPE. Reported compliance rates varied from "very low" to 97%. Many hospitals (28%) reported difficulties related to visitor compliance with isolation precautions, including hostility and refusal to comply.

CONCLUSIONS

Our study results illuminated hospital policy variations for visitor isolation precautions. Reported problems with hospital visitor policies (eg, different policies across departments or facilities) suggest the need for standard guidelines and for enhanced public awareness about the importance of visitor compliance with isolation precautions.

Is evidence guiding practice? Reported versus observed adherence to contact precautions: a pilot study

BACKGROUND

Hospital-acquired infections are a major patient safety issue. We examined staff members' knowledge, attitudes, reported and observed adherence to guidelines, and perceptions of barriers to use of contact precautions.

METHODS

A survey and nonparticipant observation study was used to examine knowledge, attitudes, perceptions, and actual behavior of staff on 3 medical/surgical units at a 600-bed Magnet-designated academic medical center (MDAMC) and a 110-bed community medical center (CMC) in the southeastern United States.

RESULTS

Correct knowledge answers ranged from 75% (CMC) to 100% (MDAMC). CMC participants were less likely to perceive time as a barrier (5% vs 25%; P = .050); more MDAMC participants were motivated by supervisors' recognition (87% vs 33%; P = .001). No statistically significant differences existed between groups on reported behaviors. Upon observation, fewer CMC participants demonstrated 4 of 5 evidence-based contact precaution behaviors compared with MDMC participants (P < .001). Hand hygiene before glove application was similarly low at both sites.

CONCLUSIONS

Despite a decade of focus on improving patient safety, low adherence to evidence-based practice guidelines for implementation of contact precautions remains. Ongoing efforts are needed both at the system and practitioner level to improve practice adherence.

Hand hygiene compliance in patients under contact precautions and in the general hospital population

INTRODUCTION

Hand hygiene (HH) is the single most important intervention for preventing hospital-acquired infections. Contact precautions are a series of actions that infection control units take to reduce the transmission of nosocomial pathogens.

METHODS

We conducted an observational study of HH compliance. Observations were stratified as opportunities in patients under contact precautions and in the general hospital population. Trained infection control personnel performed all direct evaluations.

RESULTS

A total of 3,270 opportunities were recorded. HH compliance was statistically higher in patients on contact precautions than in the overall population (70.3% vs 60.4%; P = .0001). Critical care areas had higher HH compliance when patients were isolated by contact precautions. Medical wards were statistically lower in HH when patients were under contact precautions. Respiratory technicians had the highest HH compliance in both overall performance and in patients under contact precautions. Medical students had a lower HH compliance in both evaluations (P < .001).

CONCLUSIONS

We noted greater compliance with HH practices when patients were under contact precaution in comparison with the overall hospital population. The difference was stronger in intensive care areas and lower among medical students.

Implementation of hospital-wide enhanced terminal cleaning of targeted patient rooms and its impact on endemic Clostridium difficile infection rates

BACKGROUND

Implementation of a hospital-wide program of terminal cleaning of patient rooms revolving around hydrogen peroxide vapor (HPV) technology and evaluation of its impact on endemic nosocomial Clostridium difficile-associated diarrhea (CDAD) have not been previously reported.

METHODS

This was a retrospective quasiexperimental study involving a 900-bed community hospital. During the preintervention period (January 2007-November 2008), rooms vacated by patients with CDAD or on contact precautions for other targeted pathogens underwent 1 or more rounds of cleaning with bleach. During the intervention period (January-December 2009), targeted newly evacuated rooms underwent "enhanced cleaning" consisting of use of bleach followed by HPV decontamination utilizing a priority scale based on the pathogen and room location. Rooms vacated by patients with CDAD but for which HPV decontamination was not possible the same day underwent 4 rounds of cleaning with bleach instead.

RESULTS

During the intervention period, 1,123 HPV decontamination rounds were performed involving 96.7% of hospital rooms. Of 334 rooms vacated by patients with CDAD (May-December 2009), 180 (54%) underwent HPV decontamination. The rate of nosocomial CDAD rate dropped significantly from 0.88 cases/1,000 patient-days to 0.55 cases/1,000 patient-days (rate ratio, 0.63; 95% confidence interval: 0.50-0.79, P < .0001).

CONCLUSION

A hospital-wide program of enhanced terminal cleaning of targeted patient rooms revolving around HPV technology was practical and was associated with a significant reduction in CDAD rates.

Are health care workers protected? An observational study of selection and removal of personal protective equipment in Canadian acute care hospitals

BACKGROUND

The proper use of personal protective equipment (PPE) by health care workers (HCWs) is vital in preventing the spread of infection and has implications for HCW safety.

METHODS

An observational study was performed in 11 hospitals participating in the Canadian Nosocomial Infection Surveillance Program between January 7 and March 30, 2011. Using a standardized data collection tool, observers recorded HCWs selecting and removing PPE and performing hand hygiene on entry into the rooms of febrile respiratory illness patients.

RESULTS

The majority of HCWs put on gloves (88%, n = 390), gown (83%, n = 368), and mask (88%, n = 386). Only 37% (n = 163) were observed to have put on eye protection. Working in a pediatric unit was significantly associated with not wearing eye protection (7%), gown (70%), gloves (77%), or mask (79%). Half of the observed HCWs (54%, n = 206) removed their PPE in the correct sequence. Twenty-six percent performed hand hygiene after removing their gloves, 46% after removing their gown, and 57% after removing their mask and/or eye protection.

CONCLUSION

Overall adherence with appropriate PPE use in health care settings involving febrile respiratory illness patients was modest, particularly on pediatric units. Interventions to improve PPE use should be targeted toward the use of recommended precautions (eg, eye protection), HCWs working in pediatric units, the correct sequence of PPE removal, and performing hand hygiene.

Infection prevention practices in adult intensive care units in a large community hospital system after implementing strategies to reduce health care-associated, methicillin-resistant Staphylococcus aureus infections

BACKGROUND

A range of strategies and approaches have been developed for preventing health care-associated infections. Understanding the variation in practices among facilities is necessary to improve compliance with existing programs and aid the implementation of new interventions.

METHODS

In 2009, HCA Inc administered an electronic survey to measure compliance with evidence-based infection prevention practices as well as identify variation in products or methods, such as use of special approach technology for central vascular catheters and ventilator care. Responding adult intensive care units (ICUs) were those considering participation in a clinical trial to reduce health care-associated infections.

RESULTS

Responses from 99 ICUs in 55 hospitals indicated that many evidenced-based practices were used consistently, including methicillin-resistant Staphylococcus aureus (MRSA) screening and use of contact precautions for MRSA-positive patients. Other practices exhibited wide variability including discontinuation of precautions and use of antimicrobial technology or chlorhexidine patches for central vascular catheters. MRSA decolonization was not a predominant practice in ICUs.

CONCLUSION

In this large, community-based health care system, there was substantial variation in the products and methods to reduce health care-associated infections. Despite system-wide emphasis on basic practices as a precursor to adding special approach technologies, this survey showed that these technologies were commonplace, including in facilities where improvement in basic practices was needed.

Improving staff compliance with isolation precautions through use of an educational intervention and behavioral contract

Hospital-acquired infections negatively impact patient outcomes, length of stay, and the economy. Health care systems must find ways to decrease the spread of infection and the development of infection with the use of isolation precautions in an acute care setting. All staff members must be aware of ways to decrease or prevent the spread of infection by the appropriate use of isolation precautions. This article describes a successful program that improved the use of isolation precautions among nursing personnel through the implementation of an educational intervention and behavioral contract.

Nurses' uniforms: How many bacteria do they carry after one shift?

This pilot study investigated the pathogens that nurses are potentially bringing into the public and their home when they wear work uniforms outside of the work environment. To achieve this, sterilized uniforms were distributed to 10 nurses at a local hospital in Washington State at the beginning of their shift. Worn uniforms were collected at the end of the shifts and sent to a laboratory for analysis. Four tests were conducted: 1) a heterotrophic growth plate count, 2) methicillin-resistant Staphylococcus aureus (MRSA) growth, 3) vancomycin-resistant Enterococci (VRE), and 4) identification of the heterotrophic plate counts. Each participant completed a questionnaire and a survey. The results showed that the average bacteria colony growth per square inch was 1,246 and 5,795 for day and night shift, respectively. After 48 h, MRSA positives were present on 4 of the day shift and 3 of the night shift uniforms. Additional bacteria identified include: Bacillus sp., Micrococcus luteus, Staphylococcus aureus, Staphylococcus epidermidis, and Micrococcus roseus. The significant presence of bacteria on the uniforms 48 h after the shift ended necessitates further study, discussions and policy consideration regarding wearing health care uniforms outside of the work environment.

The potential regional impact of contact precaution use in nursing homes to control methicillin-resistant Staphylococcus aureus

OBJECTIVE

Implementation of contact precautions in nursing homes to prevent methicillin-resistant Staphylococcus aureus (MRSA) transmission could cost time and effort and may have wide-ranging effects throughout multiple health facilities. Computational modeling could forecast the potential effects and guide policy making.

DESIGN

Our multihospital computational agent-based model, Regional Healthcare Ecosystem Analyst (RHEA).

SETTING

All hospitals and nursing homes in Orange County, California.

METHODS

Our simulation model compared the following 3 contact precaution strategies: (1) no contact precautions applied to any nursing home residents, (2) contact precautions applied to those with clinically apparent MRSA infections, and (3) contact precautions applied to all known MRSA carriers as determined by MRSA screening performed by hospitals.

RESULTS

Our model demonstrated that contact precautions for patients with clinically apparent MRSA infections in nursing homes resulted in a median 0.4% (range, 0%-1.6%) relative decrease in MRSA prevalence in nursing homes (with 50% adherence) but had no effect on hospital MRSA prevalence, even 5 years after initiation. Implementation of contact precautions (with 50% adherence) in nursing homes for all known MRSA carriers was associated with a median 14.2% (range, 2.1%-21.8%) relative decrease in MRSA prevalence in nursing homes and a 2.3% decrease (range, 0%-7.1%) in hospitals 1 year after implementation. Benefits accrued over time and increased with increasing compliance.

CONCLUSIONS

Our modeling study demonstrated the substantial benefits of extending contact precautions in nursing homes from just those residents with clinically apparent infection to all MRSA carriers, which suggests the benefits of hospitals and nursing homes sharing and coordinating information on MRSA surveillance and carriage status.

Impact of the 2009 influenza A (H1N1) pandemic on Canadian health care workers: a survey on vaccination, illness, absenteeism, and personal protective equipment

BACKGROUND

Data are limited on the impact of the 2009 H1N1 influenza A pandemic on health care worker (HCW) vaccination, illness, absenteeism, and personal protective equipment (PPE) use.

METHODS

A survey was completed by HCWs from 14 hospitals participating in the Canadian Nosocomial Infection Surveillance Program who provided direct care to patients with pH1N1 influenza in high-risk units between September and December 2009.

RESULTS

Surveys were returned from 986 HCWs (80% nurses, 14% respiratory therapists, and 6% physicians). HCWs working in an intensive care unit (78%) or a designated influenza ward (67%) were more compliant with wearing an N95 respirator for aerosol-generating medical procedures than those working in an emergency department (47%; P < .001). HCWs who worked in health care for >11 years were more compliant with wearing protective eyewear than those who worked for ≤11 years (69% vs 54%; P < .001). A total of 815 HCWs (83%) reported having received the pH1N1 influenza vaccine, and 372 (38%) reported having received the 2009-2010 seasonal influenza vaccine. Influenza-like illness was reported by 236 (24%) HCWs, 170 of whom (72%) reported missing work.

CONCLUSIONS

Experience working in health care improves PPE use and HCWs in emergency departments should be targeted for interventions to improve PPE compliance. pH1N1 influenza vaccine coverage was high, but seasonal influenza vaccine coverage was low, and significant HCW illness and absenteeism were reported.

Laboratory-acquired brucellosis in Turkey

BACKGROUND

Laboratory healthcare workers (HCWs) are at risk of laboratory-acquired brucellosis (LAB).

AIM

To describe the risk factors of LAB among HCWs.

METHODS

A multicentre survey study was conducted by face-to-face interview in 38 hospitals from 17 provinces of Turkey. A structured survey was administered to the HCWs, working in infectious diseases clinics and microbiology departments, who were at risk of brucella infection.

FINDINGS

The survey response rate was 100%. Of the 667 laboratory workers, 38 (5.8%) had a history of LAB. In multivariate analysis, factors independently associated with an increased risk of LAB included working with the brucella bacteria (odds ratio: 5.12; 95% confidence interval: 2.28-11.52; P < 0.001) and male gender (2.14; 1.02-4.45; P = 0.042). Using a biosafety cabinet level 2 (0.13; 0.03-0.60; P = 0.009), full adherence to glove use (0.27; 0.11-0.65; P = 0.004) and longer duration of professional life (0.86; 0.80-0.92; P < 0.001) were found to be protective.

CONCLUSIONS

Working with the brucella bacteria, being male, a lack of compliance with personal protective equipment and biosafety cabinets were the independent risk factors for the development of LAB in our series. Increased adherence to personal protective equipment and use of biosafety cabinets should be priority targets to prevent LAB.

Measuring compliance with transmission-based isolation precautions: comparison of paper-based and electronic data collection

Background

Decreasing the transmission of resistant organisms in hospitals is a key goal of infection prevention plans. Studies have consistently shown inadequate health care worker (HCW) compliance with isolation precautions. Evaluating adherence through direct observation of HCW behavior is considered the “gold standard” but is labor-intensive, requiring the collection and analysis of a large volume of observations.

Methods

Two methods of data collection to assess HCW compliance were evaluated: a manual method using a paper form (PF), with subsequent data entry into a database, and an electronic method using a Web-based form (WBF) with real-time data recording. Observations were conducted at 4 hospitals (a total of 2,065 beds) to assess the availability of gloves, gowns, and masks; isolation sign postings; and HCW isolation practices.

Results

A total of 13,878 isolation rooms were observed in 2009. The median number of rooms observed per day was 61 for PF and 60 for WBF, and the respective mean observation times per room were 149 seconds and 60 seconds. Thus, use of the WBF provided a time savings of 89 seconds per room.

Conclusion

Simple electronic forms can significantly decrease the required resources for monitoring HCW adherence to hospital policies. Use of the WBF decreased the observation time by 60%, allowing for increases in the frequency and intensity of surveillance activities.

Use of adherence monitors as part of a team approach to control clonal spread of multidrug-resistant Acinetobacter baumannii in a research hospital

BACKGROUND

Multidrug-resistant Acinetobacter baumannii (MDRAB) is difficult to treat and eradicate. Several reports describe isolation and environmental cleaning strategies that controlled hospital MDRAB outbreaks. Such interventions were insufficient to interrupt MDRAB transmission in 2 intensive care unit-based outbreaks in our hospital. We describe strategies that were associated with termination of MDRAB outbreaks at the National Institutes of Health Clinical Center.

METHODS

In response to MDRAB outbreaks in 2007 and 2009, we implemented multiple interventions, including stakeholder meetings, enhanced isolation precautions, active microbial surveillance, cohorting, and extensive environmental cleaning. We conducted a case-control study to analyze risk factors for acquiring MDRAB. In each outbreak, infection control adherence monitors were placed in MDRAB cohort areas to observe and correct staff infection control behavior.

RESULTS

Between May 2007 and December 2009, 63 patients acquired nosocomial MDRAB; 57 (90%) acquired 1 or more of 4 outbreak strains. Of 347 environmental cultures, only 2 grew outbreak strains of MDRAB from areas other than MDRAB patient rooms. Adherence monitors recorded 1,330 isolation room entries in 2007, of which 8% required interventions. In 2009, around-the-clock monitors recorded 4,892 staff observations, including 127 (2.6%) instances of nonadherence with precautions, requiring 68 interventions (1.4%). Physicians were responsible for more violations than other staff (58% of hand hygiene violations and 37% of violations relating to gown and glove use). Each outbreak terminated in temporal association with initiation of adherence monitoring.

CONCLUSIONS

Although labor intensive, adherence monitoring may be useful as part of a multifaceted strategy to limit nosocomial transmission of MDRAB.

Contact precautions for multidrug-resistant organisms: Current recommendations and actual practice

BACKGROUND

Contact precautions are recommended for interactions with patients colonized/infected with multidrug-resistant organisms; however, actual rates of implementation of contact precautions are unknown.

METHODS

Observers recorded the availability of supplies and staff/visitor adherence to contact precautions at rooms of patients indicated for contact precautions. Data were collected at 3 sites in a New York City hospital network.

RESULTS

Contact precautions signs were present for 85.4% of indicated patients. The largest proportions were indicated for isolation for vancomycin-resistant enterococci and methicillin-resistant Staphylococcus aureus cultures. Isolation carts were available outside 93.7% to 96.7% of rooms displaying signs, and personal protective equipment was available at rates of 49.4% to 72.1% for gloves (all sizes: small, medium, and large) and 91.7% to 95.2% for gowns. Overall adherence rates on room entry and exit, respectively, were 19.4% and 48.4% for hand hygiene, 67.5% and 63.5% for gloves, and 67.9% and 77.1% for gowns. Adherence was significantly better in intensive care units (P < .05) and by patient care staff (P < .05), and patient care staff compliance with one contact precautions behavior was predictive of adherence to additional behaviors (P < .001).

CONCLUSIONS

Our findings support the recommendation that methods to monitor contact precautions and identify and correct nonadherent practices should be a standard component of infection prevention and control programs.

Assessing the role of undetected colonization and isolation precautions in reducing methicillin-resistant Staphylococcus aureus transmission in intensive care units

Background

Screening and isolation are central components of hospital methicillin-resistant Staphylococcus aureus (MRSA) control policies. Their prevention of patient-to-patient spread depends on minimizing undetected and unisolated MRSA-positive patient days. Estimating these MRSA-positive patient days and the reduction in transmission due to isolation presents a major methodological challenge, but is essential for assessing both the value of existing control policies and the potential benefit of new rapid MRSA detection technologies. Recent methodological developments have made it possible to estimate these quantities using routine surveillance data.

Methods

Colonization data from admission and weekly nares cultures were collected from eight single-bed adult intensive care units (ICUs) over 17 months. Detected MRSA-positive patients were isolated using single rooms and barrier precautions. Data were analyzed using stochastic transmission models and model fitting was performed within a Bayesian framework using a Markov chain Monte Carlo algorithm, imputing unobserved MRSA carriage events.

Results

Models estimated the mean percent of colonized-patient-days attributed to undetected carriers as 14.1% (95% CI (11.7, 16.5)) averaged across ICUs. The percent of colonized-patient-days attributed to patients awaiting results averaged 7.8% (6.2, 9.2). Overall, the ratio of estimated transmission rates from unisolated MRSA-positive patients and those under barrier precautions was 1.34 (0.45, 3.97), but varied widely across ICUs.

Conclusions

Screening consistently detected >80% of colonized-patient-days. Estimates of the effectiveness of barrier precautions showed considerable uncertainty, but in all units except burns/general surgery and one cardiac surgery ICU, the best estimates were consistent with reductions in transmission associated with barrier precautions.

Aspectos de biossegurança relacionados ao uso do jaleco pelos profissionais de saúde: uma revisão da literatura

O estudo objetivou analisar a literatura publicada a respeito dos aspectos da biossegurança relacionados ao uso do jaleco pelos profissionais da saúde. Trata-se de uma revisão narrativa da literatura publicada no período de 1991 a 2008. Utilizou-se as bases de dados MEDLINE, LILACS e SciELO, sendo selecionados 22 artigos que foram agrupados para análise considerando os enfoques priorizados em: infecções cruzadas causadas por jalecos; jalecos contaminados; flora bacteriana em jalecos dos profissionais de saúde. O jaleco foi abordado como fonte de contaminação e como equipamento de proteção individual na prevenção das infecções. Portanto, são necessárias campanhas educativas no sentido de orientar os profissionais de saúde sobre o uso de jaleco.

Prevention of hospital-acquired infections: review of non-pharmacological interventions

Hospital-acquired (nosocomial) infections (HAIs) increase morbidity, mortality and medical costs. In the USA alone, nosocomial infections cause about 1.7 million infections and 99 000 deaths per year. HAIs are spread by numerous routes including surfaces (especially hands), air, water, intravenous routes, oral routes and through surgery. Interventions such as proper hand and surface cleaning, better nutrition, sufficient numbers of nurses, better ventilator management, use of coated urinary and central venous catheters and use of high-efficiency particulate air (HEPA) filters have all been associated with significantly lower nosocomial infection rates. Multiple infection control techniques and strategies simultaneously ('bundling') may offer the best opportunity to reduce the morbidity and mortality toll of HAIs. Most of these infection control strategies will more than pay for themselves by saving the medical costs associated with nosocomial infections. Many non-pharmacological interventions to prevent many HAIs will also reduce the need for long or multiple-drug antibiotic courses for patients. Lower antibiotic drug usage will reduce risk of antibiotic-resistant organisms and should improve efficacy of antibiotics given to patients who do acquire infections.

Review of personal protection equipment used in practice

Standard precautions offer a consistent approach to infection control that does not rely on knowledge or suspicion of infection, and contributes to staff and patient safety by reducing the risk of exposure to potentially infectious material. One of the cornerstones of standard precautions is the appropriate use of personal protective equipment (PPE) whenever contact with blood or body fluids is anticipated. However, evidence suggests that compliance with standard precautions including correct use of PPE is inadequate. Demographic and epidemiological changes in the U.K., and the drive to provide more complex patient care outside acute hospitals may lead to increased infection risks for both patients and community healthcare workers. This review examines the importance and use of PPE by community nurses and discusses the implications for practice of poor compliance with standard precautions. Recommendations for practice will be made aimed at improving compliance with this important element of standard precautions.
