Hand hygiene in emergency medical services

Prevalence of methicillin sensitive and resistant Staphylococcus aureus carriage among German emergency medical providers

Background

Health care workers (HCW) in Emergency Medical Services (EMS) frequently come into contact with carriers of methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA) strains and may acquire and transmit them to patients. However, there is little data on MSSA and MRSA colonization of medical personnel in the emergency services. Additionally, few studies have analyzed the association between personal hygiene of staff and colonization. Therefore, we examined the prevalence of MSSA and MRSA in EMS staff of two German regions and evaluated their personal hygiene behavior.

Method

Throat and nasal swabs from 300 EMS workers were analyzed. Both direct and pre-enriched cultures of the swabs were cultivated on culture media to identify MSSA and MRSA. Results were analyzed together with questionnaires about sociodemographic data and a self-assessment of hygiene behavior. Statistical analysis was done using the R statistical software.

Results

Of the total 300 swabs, 55% were from paramedics, 39% were from emergency medical technicians (EMT) and 5% were from emergency physicians. With 1%, the MRSA prevalence was comparable to that of the German population, while the MSSA rate - 43.7% - was higher than expected. Colonization with MSSA was significantly associated with poor hand hygiene and male sex, and was inversely correlated to time on the job in EMS.

Conclusion

The sample size of 300 and a MRSA prevalence of 1% made a meaningful analysis of potential influencing factors on the prevalence of MRSA infeasible. The comparatively high prevalence of MSSA and the association with decreasing frequency of hand antisepsis suggests an influence of personal hygiene on MSSA colonization. HCW in EMS should be encouraged to make use of their personal protective equipment and practice frequent hand hygiene. The implementation of diagnostic tools such as the Hand Hygiene Self-Assessment Framework of the WHO could be utilized to reveal problems in organizations, followed by an individual program to promote hand hygiene.

Hand hygiene in emergencies: Multiprofessional perceptions from a mixed methods based online survey in Germany

Introduction

Despite high vulnerability to infection, hand disinfection compliance in emergencies is low. This is regularly justified as the disinfection procedure delays life support, and instead, wearing disposable gloves is preferred. Simulation studies showed higher achievable compliance than detected in real-life situations. This study aimed to explore healthcare providers' attitudes toward hand disinfection and using gloves in emergencies.

Methods

We conducted an anonymous online survey in Germany on the attitude and subjective behavior in the five moments of hand hygiene in a closed environment and an open convenience sampling survey. Statistics included paired student's t-tests corrected for multiple testing. For qualitative analysis, we employed a single-coder approach.

Results

In 400 participants, we detected low priority of WHO-1 (before touching a patient) and WHO-2 (before clean/aseptic procedure) hand hygiene moments, despite knowing the risks of omission of hand disinfection. For all moments, self-assessment exceeded the assessment of colleagues (p < 0.001). For WHO-3, we detected a lower disinfection priority for wearing gloves compared to contaminated bare hands. Qualitative analyses revealed five themes: basic conditions, didactic implementations, cognitive load, and uncertainty about feasibility and efficacy.

Discussion

Considering bias, the study's subjective nature, the unknown role of emergency-related infections contributing to hospital-acquired infections, and different experiences of healthcare providers, we conclude that hand disinfection before emergencies is de-prioritized and justified by the emergency situation regardless of the objective feasibility.

Conclusion

This study reveals subjective and objective barriers to implementation of WHO-1 and WHO-2 moments of hand disinfection to be further evaluated and addressed in educational programs.

SARS-CoV-2 Contamination of Ambulance Surfaces and Effectiveness of Routine Decontamination Procedure: A Classic Hygiene Lesson for A Novel Pathogen

The efficacy of standard operating procedures (SOPs) for the decontamination of ambulances against SARS-CoV-2 has been debated. In Italy, the differential use of ambulances was implemented by regional health authorities, with selected vehicles being used exclusively for transporting COVID-19 patients. We investigated the presence of SARS-CoV-2 on high-touch surfaces in ambulances to assess contamination dynamics and the effectiveness of decontamination SOPs. Four high-touch surfaces were sampled before and after decontamination (T0; T1). The gloves of the EMS crew chief were also sampled. RNA extraction was performed with a commercial kit, followed by RT-qPCR molecular detection of SARS-CoV-2. A total of 11 transports were considered. Seven transports had at least one positive sample; all were related to a COVID-19 patient. Three of the negative transports had dealt with COVID-19 case, and one had dealt with a COVID-19-negative patient. One door handle and one oxygen knob were positive at T0, with negative T1 swabs. The monitors were positive in 5 transports at T0, yet they were never positive at T1. Three stretcher handles tested positive at T0, and two of them also at T1, possibly having bypassed decontamination during personnel dismounting. Gloves were contaminated in five transports, in which 1 to 3 additional samples (monitor, knob, stretcher) resulted as positive. Overall, the efficacy of decontamination SOPs was confirmed under the unprecedented conditions of the COVID-19 emergency. However, the importance of correct hand-hygiene and glove-disposal should be further emphasized through the dedicated training of EMS personnel.

Do we need a pandemic to improve hygiene routines in the ambulance service? A cross-sectional study

Background

We know that ambulance staff may have sparse knowledge on how to comply with care approaches that ensure appropriate hygiene in the ambulance, but we do not know if and how the COVID-19 pandemic has affected ambulance staff’s perceived compliance with hygiene routines.

Aim

To investigate ambulance staff’s self-reported hand hygiene (HH) perceptions and compliance; and to explore if and how the COVID-19 pandemic has affected ambulance staff’s perceived compliance with hygiene routines.

Methods

A cross-sectional study design using the WHO-validated Perception Survey for Healthcare Workers regarding hygiene. Thematic analysis and descriptive statistics were used for analysis.

Results

204 surveys were analysed, 92% of participants stated that their hygiene routine compliance had improved during the COVID-19 pandemic, and some participants also described that their colleagues’ practice had improved. These improvements were reportedly driven by the need to acquire new knowledge to deal with the pandemic and sometimes with fear.

Conclusions

Experience acquired during the pandemic needs to be sustainable if we are to increase HH and hygiene routine compliance in ambulance services. Interventions aimed at changing ambulance staff’s perceived behaviour are warranted, and stakeholders should try and identify the personal motivations that lead these staff to seek self-betterment regarding HH and hygiene routine compliance. Otherwise, the risk of patients suffering from healthcare-associated infection may not decrease as wished.

Bacteria Associated with Healthcare-Associated Infections on Environmental Samples Obtained from Two Fire Departments

(1) Background: Firefighters spend about 64% of their time responding to medical emergencies and providing medical care without a patient history, which can render them vulnerable to healthcare-associated infections (HAI). Infection prevention, control, and surveillance systems have been instituted at hospitals. However, the prevalence of firefighters’ exposure to HAI is unknown. The objective of this study was to document evidence of HAI on surfaces in fire stations and engines to inform disinfection procedures and identify which pathogens might contribute to occupational exposures. (2) Methods: High-touch or high-use surfaces of two fire departments were sampled during five separate occasions. One fire station from one fire department was sampled over a 4-week period, whereas four fire stations were sampled from a different fire department only once. Sampled surfaces included: entryway floor, washing machine, medical bag, back seat of engine, keyboard of reporting computer, engine console, and uniform pants. (3) Results: Multiple statistical models determined that bacterial contamination was similar between the two fire departments and their stations. Keyboards were the most contaminated surface for all fire stations and departments, E. coli was the most common bacteria detected, and C. difficile was the least detected bacteria. Adjustments for rates of contamination found that contamination rates varied between fire stations. (4) Conclusions: Comprehensive environmental sampling and clinical studies are needed to better understand occupational exposures of firefighters to HAI.

Risk of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) acquisition during ambulance transport: A retrospective propensity-score-matched cohort analysis

OBJECTIVE

To estimate the relative risk (RR) of developing methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) colonization or infection within 30 days of ambulance transport.

METHODS

We performed a retrospective cohort study of patients with a principal diagnosis of chest pain presenting to our emergency department (ED) over a 4-year period. Patients were included if they presented from and were discharged to nonhealthcare locations without being admitted. Encounters were stratified by arrival mechanism: ambulance versus private vehicle. We performed propensity score matching and multivariable logistic regression to estimate the RR for the primary outcome.

RESULTS

In total, 321,229 patients had ED encounters during the study period. After applying inclusion criteria and propensity score matching, there were 11,324 patients: 3,903 in the ambulance group and 7,421 in the unexposed group. Among them, 12 patients (0.11%) had the outcome of interest, including 9 (0.08%) with MRSA and 3 (0.03%) with VRE. The 30-day prevalence of MRSA or VRE was larger in the ambulance group than in the unexposed group: 8 (0.20%) and 4 (0.05%), respectively (P = .02). Patients who presented to the ED via ambulance were almost 4 times more likely to have MRSA or VRE within 30 days of their encounter (RR, 3.72; 95% CI, 1.09-12.71; P = .04).

CONCLUSIONS

Our cohort study is the first to demonstrate an association between ambulance exposure and pathogen incidence, representing the first step in evaluating medical-transport-associated infection burden to eventually develop interventions to address it.

Medical transport-associated infection: Review and commentary making a case for its legitimacy

The purpose of this article is to summarize existing literature about healthcare-associated infection (HAI) in the medical transport environment and to define the term medical transport-associated infection (MTAI) to unify all previous work under a single umbrella with the objective of providing a standardized definition for future research. A review of the literature yielded 34 relevant articles. These studies show that there are pathogens in the ambulance environment, that emergency medical services (EMS) personnel do not regularly comply with hygiene practices, and that patients are potentially affected by HAI as a direct result of ambulance exposure. Prospective studies must be conducted to truly understand the impact that ambulance exposure has on HAIs. MTAI is a subset of HAI and is defined as any infection acquired as a direct effect of exposure in a medical transport setting.

Effect of an E-Learning Module on Personal Protective Equipment Proficiency Among Prehospital Personnel: Web-Based Randomized Controlled Trial

Background

To avoid misuse of personal protective equipment (PPE), ensure health care workers’ safety, and avoid shortages, effective communication of up-to-date infection control guidelines is essential. As prehospital teams are particularly at risk of contamination given their challenging work environment, a specific gamified electronic learning (e-learning) module targeting this audience might provide significant advantages as it requires neither the presence of learners nor the repetitive use of equipment for demonstration.

Objective

The aim of this study was to evaluate whether a gamified e-learning module could improve the rate of adequate PPE choice by prehospital personnel in the context of the coronavirus disease (COVID-19) pandemic.

Methods

This was an individual-level randomized, controlled, quadruple-blind (investigators, participants, outcome assessors, and data analysts) closed web-based trial. All emergency prehospital personnel working in Geneva, Switzerland, were eligible for inclusion, and were invited to participate by email in April 2020. Participants were informed that the study aim was to assess their knowledge regarding PPE, and that they would be presented with both the guidelines and the e-learning module, though they were unaware that there were two different study paths. All participants first answered a preintervention quiz designed to establish their profile and baseline knowledge. The control group then accessed the guidelines before answering a second set of questions, and were then granted access to the e-learning module. The e-learning group was shown the e-learning module right after the guidelines and before answering the second set of questions.

Results

Of the 291 randomized participants, 176 (60.5%) completed the trial. There was no significant difference in baseline knowledge between groups. Though the baseline proportion of adequate PPE choice was high (75%, IQR 50%-75%), participants’ description of the donning sequence was in most cases incorrect. After either intervention, adequate choice of PPE increased significantly in both groups (P<.001). Though the median of the difference in the proportion of correct answers was slightly higher in the e-learning group (17%, IQR 8%-33% versus 8%, IQR 8%-33%), the difference was not statistically significant (P=.27). Confidence in the ability to use PPE was maintained in the e-learning group (P=.27) but significantly decreased in the control group (P=.04).

Conclusions

Among prehospital personnel with an already relatively high knowledge of and experience with PPE use, both web-based study paths increased the rate of adequate choice of PPE. There was no major added value of the gamified e-learning module apart from preserving participants' confidence in their ability to correctly use PPE.

Interhospital Transfer of Critically Ill Patients Because of Coronavirus Disease 19-Related Respiratory Failure

•

Given the prevalence and severity of illness associated with coronavirus disease 2019 (COVID-19)–related acute respiratory failure, it is very likely that community hospitals will need to transfer such patients to regional centers capable of providing advanced care, such as extracorporeal membrane oxygenation support.

•

The critical care transport team must be familiar with transporting these patients in the prone position because this position has been shown to improve oxygenation in COVID-19–positive patients with respiratory failure.

•

Critical care transport teams must be familiar with advanced modes of ventilation, such as airway pressure release ventilation, and blood gas interpretation in order to optimize safety during the transport of COVID-19–positive patients with respiratory failure.

•

Decontamination procedures must be followed closely, even if this results in prolonged downtime for the transport team, in order to ensure both crew and subsequent patient safety.

Objective

Interfacility transfer of patients with coronavirus disease 2019–related acute respiratory failure is high risk because of the severity of respiratory failure and potential for crew exposure. This article describes a hospital-based transport team's experience with interfacility transport of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)–positive patients.

Methods

A retrospective study of transports for respiratory failure caused by SARS-CoV-2 was performed. All transports were performed by a single critical care transport team. The team was already trained in advanced mechanical ventilation, blood gas interpretation, and management of shock. Guidance from the Centers for Disease Control and Prevention was followed regarding the use of personal protective equipment.

Results

Twenty patients were enrolled. The average patient age was 47 years (standard deviation [SD] = 12 years). The average Acute Physiology and Chronic Health Evaluation and Sequential Organ Failure Assessment scores were 10 (SD = 4) and 24 (SD = 7), respectively. The average transport distance and time were 18 miles (SD = 9 miles) and 25 minutes (SD = 11 minutes), respectively. Nineteen patients were intubated, 9 of whom required advanced ventilation. Two patients were transported prone. One patient experienced unintentional extubation upon transfer from the stretcher to the destination facility bed. The patient was reintubated without event. No crewmembers contracted SARS-CoV-2 infection.

Conclusion

Interfacility transfer of severely ill SARS-CoV-2–positive patients is safe and feasible.

Teaching Adequate Prehospital Use of Personal Protective Equipment During the COVID-19 Pandemic: Development of a Gamified e-Learning Module

BACKGROUND

The coronavirus disease (COVID-19) pandemic has led to increased use of personal protective equipment (PPE). Adequate use of this equipment is more critical than ever because the risk of shortages must be balanced against the need to effectively protect health care workers, including prehospital personnel. Specific training is therefore necessary; however, the need for social distancing has markedly disrupted the delivery of continuing education courses. Electronic learning (e-learning) may provide significant advantages because it requires neither the physical presence of learners nor the repetitive use of equipment for demonstration.

OBJECTIVE

Inclusion of game mechanics, or "gamification," has been shown to increase knowledge and skill acquisition. The objective of this research was to develop a gamified e-learning module to interactively deliver concepts and information regarding the correct choice and handling of PPE.

METHODS

The SERES framework was used to define and describe the development process, including scientific and design foundations. After we defined the target audience and learning objectives by interviewing the stakeholders, we searched the scientific literature to establish relevant theoretical bases. The learning contents were validated by infection control and prehospital experts. Learning mechanics were then determined according to the learning objectives, and the content that could benefit from the inclusion of game mechanics was identified.

RESULTS

The literature search resulted in the selection and inclusion of 12 articles. In addition to gamification, pretesting, feedback, avoiding content skipping, and demonstrations using embedded videos were used as learning mechanics. Gamification was used to enhance the interactivity of the PPE donning and doffing sequences, which presented the greatest learning challenges. The module was developed with Articulate Storyline 3 to ensure that it would be compatible with a wide array of devices, as this software generates HTML5-compatible output that can be accessed on smartphones, tablets, and regular computers as long as a recent browser is available.

CONCLUSIONS

A gamified e-learning module designed to promote better knowledge and understanding of PPE use among prehospital health care workers was created by following the SERES framework. The impact of this module should now be assessed by means of a randomized controlled trial.

EMS Disease Exposure, Transmission, and Prevention: a Review Article

Purpose of Review

This article aims to review recent literature regarding the risks of disease exposure to pre-hospital providers and the patients they serve, as well as the challenges they face in minimizing transmission and exposure.

Recent Findings

Many studies continue to show poor compliance with consistent universal precautions, as well as proper hand hygiene. Vaccination rates are suboptimal despite attempts to encourage compliance. With the spread of multi-drug resistant organisms, new techniques of decontamination need to be investigated.

Summary

There remains a general lack of information and studies regarding the risks of disease exposure and transmission to EMS providers despite the significance hazards their profession can pose. However, there remains a continued theme throughout the majority of EMS and pre-hospital studies, demonstrating that hand washing and consistent use of personal protective equipment remains a persistent, preventable means of disease exposure and transmission.

Compliance with hand hygiene in emergency medical services: an international observational study

INTRODUCTION

Healthcare-associated infection caused by insufficient hygiene is associated with mortality, economic burden, and suffering for the patient. Emergency medical service (EMS) providers encounter many patients in different surroundings and are thus at risk of posing a source of microbial transmission. Hand hygiene (HH), a proven infection control intervention, has rarely been studied in the EMS.

METHODS

A multicentre prospective observational study was conducted from December 2016 to May 2017 in ambulance services from Finland, Sweden, Australia and Denmark. Two observers recorded the following parameters: HH compliance according to WHO guidelines (before patient contact, before clean/aseptic procedures, after risk of body fluids, after patient contact and after contact with patient surroundings). Glove use and basic parameters such as nails, hair and use of jewellery were also recorded.

RESULTS

Sixty hours of observation occurred in each country, for a total of 87 patient encounters. In total, there were 1344 indications for HH. Use of hand rub or hand wash was observed: before patient contact, 3%; before clean/aseptic procedures, 2%; after the risk of body fluids, 8%; after patient contact, 29%; and after contact with patient-related surroundings, 38%. Gloves were worn in 54% of all HH indications. Adherence to short or up done hair, short, clean nails without polish and no jewellery was 99%, 84% and 62%, respectively. HH compliance was associated with wearing gloves (OR 45; 95% CI 10.8 to 187.8; p=0.000) and provider level (OR 1.7; 95% CI 1.1 to 2.4; p=0.007), but not associated with gender (OR 1.3; 95% CI 0.9 to 1.9; p=0.107).

CONCLUSION

HH compliance among EMS providers was remarkably low, with higher compliance after patient contacts compared with before patient contacts, and an over-reliance on gloves. We recommend further research on contextual challenges and hygiene perceptions among EMS providers to clarify future improvement strategies.

"Hand hygiene perception and self-reported hand hygiene compliance among emergency medical service providers: a Danish survey"

Background

Hand hygiene (HH), a cornerstone in infection prevention and control, lacks quality in emergency medical services (EMS). HH improvement includes both individual and institutional aspects, but little is known about EMS providers’ HH perception and motivations related to HH quality. Therefore, we aimed to investigate the HH perception and assess potential factors related to self-reported HH compliance among the EMS cohort.

Methods

A cross-sectional, self-administered questionnaire consisting of 24 items (developed from the WHOs Perception Survey for Health-Care Workers) provided information on demographics, HH perceptions and self-reported HH compliance among EMS providers from Denmark.

Results

Overall, 457 questionnaires were answered (response rate 52%). Most respondents were advanced-care providers, males, had > 5 years of experience, and had received HH training < 3 years ago. HH was perceived a daily routine, and the majority rated their HH compliance rate ≥ 80%. Both infection severity and the preventive effect of HH were acknowledged. HH quality was perceived important to colleagues and patients, but not as much to managers. Access to supplies, simple instructions and having or being “a good example” were perceived most effective to improve HH compliance. Self-reported HH compliance was associated with years of experience and perceptions of HCAI’s impact on patient outcome, HH’s preventive effect, organizational priority, HH’s importance to colleagues and patients, and the effort HH requires (p ≤ 0.05).

Conclusion

Danish EMS providers acknowledged the impact of infections and the preventive effect of HH, and perceived access to HH supplies at the point of care, having or being “a good example” and simple instructions effective to improve HH compliance. Moreover, several behavioral-, normative- and control beliefs were associated with self-reported HH compliance, and thus future improvement strategies should be multimodal.

High nursing workload is a main associated factor of poor hand hygiene adherence in Beijing, China: An observational study

AIM

The aim of the study was to explore the impact of nurse workloads on adherence to hand hygiene.

BACKGROUND

Adherence to hand hygiene and nursing workloads have been linked to quality of patient care. Therefore, it was important to understand the relationship to safe patient care.

DESIGN

This cross-sectional study was performed from January 2016 to June 2016.

METHODS

Workloads and adherence to hand hygiene for nurses on 3-day shifts in a tertiary hospital were investigated in 2016. Actual hours worked per shift were timed using a stopwatch to assess nursing workloads. Descriptive and inferential statistics and multiple variable regression analysis were used to analyse the data.

RESULTS

Sixty-four nurses from four wards were observed. The average adherence rate of hand hygiene was 26.6% and the average nursing workload per shift was 6.7 hours. Multiple regression revealed that nursing workload was negatively related to adherence rate of hand hygiene.

CONCLUSION

Nurses in this study that had a low rate of adherence with hand hygiene frequently had high workloads. Adherence to hand hygiene was independently associated with actual hours worked per shift.

Prehospital infection control and prevention in Denmark: a cross-sectional study on guideline adherence and microbial contamination of surfaces

Background

Prehospital acute care and treatment have become more complex, and while invasive procedures are standard procedures, focus on infection control and prevention is scarce. We aimed to evaluate guideline adherence, microbial contamination, and associated risk factors.

Methods

In a nationwide cross-sectional study, we evaluated guideline adherence to thorough cleaning (TC) once a day, and moderate cleaning (MC) in-between patient courses. Microbial contamination on hand-touch sites (HTS) and provider-related sites (PRS) was assessed by total aerobic colony forming units (CFU) and presence of selected pathogens, using swab and agar imprints. Also, microbial contamination was assessed in relation to potential risk factors.

Results

80 ambulances and emergency medical service (EMS) providers were enrolled. Adherence to guidelines regarding TC was 35%, but regarding MC it was 100%. In total, 129 (27%) of 480 HTS presented a total CFU > 2.5/cm² and/or pathogenic growth, indicating hygiene failures. The prevalence of selected pathogens on HTS was: S. aureus 7%; Enterococcus 3% and Enterobacteriaceae 1%. Total CFU on the PRS ranged from 0 to 250/cm², and the prevalence of pathogens was 18% (S. aureus 15%, Enterococcus 3% and Enterobacteriaceae 0.3%). Methicillin-resistant S. aureus was found in one sample, and Vancomycin-resistant Enterococcus in two. No Enterobacteriaceae with extended-spectrum beta-lactamases were recorded.

Conclusion

Guideline adherence was suboptimal, and many HTS did not comply fully with proposed standards for cleanliness. Pathogens were demonstrated on both HTS and PRS, indicating that the EMS may be a source of infection in hospitalized patients. Moreover, cleaning effort and time appears associated with microbial contamination, but a comprehensive investigation of risk factors is needed.

Impact of active surveillance and infection control measures on carbapenem-resistant Gram-negative bacterial colonization and infections in intensive care

BACKGROUND

Carbapenem-resistant Gram-negative bacteria (CRGNB) infections constitute a global threat for critically ill patients and the outcome of their hospitalization. Early identification of CRGNB through rectal surveillance cultures and routine infection control measures including contact precautions, use of appropriate disinfectants, staff education on cleaning, and hand hygiene may reduce the dissemination of CRGNB.

AIM

To assess the impact of enhanced infection control measures on CRGNB infections in a nine-bed polyvalent intensive care unit in a tertiary level hospital in an endemic area.

METHODS

A quasi-experimental study, which included patients with CRGNB infection retrospectively for six months and those participating in an active surveillance programme prospectively for the subsequent 22 months. Active surveillance programme (weekly rectal swabs) was implemented including two sub-periods with infection control measures and enhanced infection control measures. CRGNB incidence, prevalence, colonization pressure, infections and compliance with infection control measures and enhanced infection control measures were recorded. Analysis was performed through time-series and interrupted time-series.

FINDINGS

During the active surveillance programme, enhanced infection control measures led to a steeper downwards trend in incidence, prevalence, and colonization pressure for CRGNB compared to the infection control measures sub-period. The linear trend was for carbapenem-resistant Klebsiella pneumoniae (CRKP) and Pseudomonas aeruginosa (CRPA) infections to decrease from 19.6 to 8.1 infections per 1000 bed-days (IBD) (P = 0.001) and from 5.1 to 1.79 IBD (P = 0.043), respectively. By contrast, carbapenem-resistant Acinetobacter baumannii infections increased from 5.2 to 15.3 IBD (P = 0.001).

CONCLUSION

Enhanced infection control measures including enhanced hand hygiene, active surveillance combined with contact precautions, education, audits and feedback policies and interventions could reduce CRKP and CRPA in endemic areas.

Self-reported behaviors and perceptions of Australian paramedics in relation to hand hygiene and gloving practices in paramedic-led health care

BACKGROUND

Noncompliance with recommended hand hygiene and gloving practices by workers in the emergency medical services may contribute to the transmission of health care-associated infections and lead to poor patient outcomes. The aim of this study was to explore the self-reported behaviors and perceptions of Australian paramedics in relation to their hand hygiene and gloving practices in paramedic-led health care.

METHODS

A national online survey (n = 417; 17% response rate) and 2 semistructured focus groups (6 per group) were conducted with members of Paramedics Australasia.

RESULTS

Although most of the study participants perceived hand hygiene and gloving to be important, the findings suggest poor compliance with both practices, particularly during emergency cases. All participants reported wearing gloves throughout a clinical case, changing them either at the completion of patient care or when visibly soiled or broken. Hand hygiene was missed at defined moments during patient care, possibly from the misuse of gloves.

CONCLUSIONS

Paramedic hand hygiene and gloving practices require substantial improvement to lower potential transmission of pathogens and improve patient safety and clinical care. Further research is recommended to explore how to alleviate the barriers to performing in-field hand hygiene and the misuse of gloves during paramedic-led health care.

Methicillin-resistant Staphylococcus aureus in Ohio EMS Providers: A Statewide Cross-sectional Study

The objective was to determine the nasal carriage prevalence of methicillin-resistant Staphylococcus aureus (MRSA) among emergency medical service (EMS) personnel and the associated risk factors. A cross-sectional study was conducted among Ohio EMS personnel randomly sampled from 84 urban and rural agencies. Surveys assessing demographics, occupational history, health, cohabitation status, and hygiene practice were collected with nasal swabs from those who enrolled. Survey weight adjusted analysis was performed (1) to estimate MRSA nasal carriage prevalence of Ohio EMS providers, and (2) to identify variables associated with MRSA. MRSA was detected in 4.6% (13/280) EMS personnel sampled. After employing a survey-weighted analysis the following risk factors associated with MRSA carriage were identified: those who did not practice frequent hand hygiene after glove use (OR, 10.51; 95% CI, 2.54-43.45; P = 0.0012), living with someone with a recent staphylococcal infection (OR, 9.02; 95% CI, 1.03-78.98; P = 0.0470), and individuals with low frequency of hand washing (< 8 times per shift) (OR, 4.20; 95% CI 1.02-17.27; P = 0.0468). An additional risk factor identified through the logistic regression analysis on the study population was EMS workers with an open wound or skin infection (OR, 6.75; 95% CI, 1.25-36.36; P = 0.0262). However, this was not significant in the survey-weighted analysis. The high prevalence of MRSA in Ohio EMS personnel is both an occupational hazard and patient safety concern. Implementing methods to reinforce CDC guidelines for proper hygiene could decrease MRSA found in the EMS setting. Previous literature suggests that a reduction in MRSA colonization can lead to decreases in transmission and improved health for both patients and personnel.
