Effect of Long-Term Use of Alcohol-Containing Handwashing Gels on the Biofilm-Forming Capacity of Staphylococcus epidermidis.

The spread of coronavirus disease 2019 (COVID-19) has promoted the use of hand sanitizers among the general population as recommended by health authorities. Alcohols, which are used in many hand sanitizers, have been shown to promotes the formation of biofilms by certain bacteria and to increase bacterial resistance to disinfection. We investigated the effect of continued use of alcohol-based gel hand sanitizer on biofilm formation by the Staphylococcus epidermidis resident strain isolated from the hands of health science students. Hand microbes were counted before and after handwashing, and the ability to produce biofilms was investigated. We found that 179 (84.8%) strains of S. epidermidis isolated from hands had the ability to form biofilm (biofilm-positive strains) in an alcohol-free culture medium. Furthermore, the presence of alcohol in the culture medium induced biofilm formation in 13 (40.6%) of the biofilm-negative strains and increased biofilm production in 111 (76.6%) strains, which were classified as low-grade biofilm-producing. Based on our findings, there is no clear evidence that the continued use of alcohol-based gels results in the selection of strains with the capacity to form biofilms. However, other disinfectant formulations that are more commonly used in clinical settings, such as alcohol-based hand-rub solutions, should be tested for their long-term effects.

Adequacy of alcohol-based handrub solution production practice in response to COVID-19 in public hospitals found in Addis Ababa, Ethiopia: a multicentered cross-sectional study

BackgroundProper hand hygiene using alcohol-based handrub (ABHR) is an effective preventive approach for the current Coronavirus Disease 2019 (COVID-19) pandemic and other infections. World Health Organization recommends local production of ABHR solution in healthcare settings which provides a feasible alternative to the use of relatively expensive commercially produced hand sanitizers. The aim of this study was to explore the adequacy of ABHR solution production practice in response to COVID-19 in public hospitals of Addis Ababa, Ethiopia.MethodsA cross-sectional observational study was applied using assessment checklist for evaluation of the adequacy of ABHR production practice in compounding units of public hospitals. The evaluation was done with regard to the standard requirements as per the checklist. Statistical Package for Social Sciences (SPSS) version 23 was used for data entry and analysis. Descriptive statistics was employed for analyses of data and categorical variables were described by frequencies and percentages.ResultsOut of the 13 public hospitals observed in the study, 11 facilities had dedicated premises for compounding of ABHR solution. Seven facilities determined the concentration of ethanol in ABHR solution using alcoholmeters. Only one health facility had a titration kit and performed a strength test for the hydrogen peroxide raw material. Thermal and chemical disinfection processes were practiced for cleaning of recycled dispensing bottles only in 3 and 2 hospitals, respectively. Most of the hospitals (11 facilities) had standard operating procedures (SOPs) for production, but the majority lack SOPs for beyond-use-date assignment (11 facilities), premise and equipment cleaning (12 facilities), and disinfection of recycled bottles (12 facilities).ConclusionMost hospitals have fulfilled the majority requirements of premises required for compounding of ABHR solution in their facilities. Five hospitals did not verify the concentration of ethanol in the ABHR solution which might affect the effectiveness of the product. Generally, lower compliance of the majority studied hospitals to good compounding practice was observed during ABHR solution production especially for product preparation, quality control, and documentation.

Perspectives of compounding pharmacists on alcohol-based hand sanitizer production and utilization for COVID-19 prevention in Addis Ababa, Ethiopia: A descriptive phenomenology study.

Globally, the safety of patients and healthcare providers is at risk due to health care-associated infections (HCAIs). World Health Organization and the Centers for Disease Control and Prevention recommend using alcohol-based hand rub (ABHR) for hand hygiene in healthcare settings to prevent HCAIs. Irrational use of ABHR will have undesirable consequences including wastage of products, exposure of healthcare providers to infections and emergence of microbial resistance to the alcohol in hand sanitizers. This study aimed to explore the perspective and experiences of compounding pharmacists on production and utilization of ABHR solution for coronavirus disease in 2019 (COVID-19) prevention in public hospitals of Addis Ababa, Ethiopia. A descriptive qualitative study using in-depth interview of 13 key-informants serving as compounding pharmacists in public hospitals of Addis Ababa, Ethiopia, was conducted. The study participants were identified and selected by purposive sampling. All transcribed interviews were subjected to thematic analysis and transcripts were analyzed manually. The compounding pharmacists in this study had a mean age of 30.6 (±3.1) years and nine of the thirteen participants were men. Ten participants believed that the compounding practice in their respective sites followed the principles of good compounding practice. More than half of the participants did not believe that ABHR products were used rationally in health facilities. They argued that users did not have enough awareness when and how to use sanitizers. Most of the interviewees reported that compounding personnel had no formal training on ABHR solution production. Study participants suggested incentive mechanisms and reimbursements for experts involved in the compounding of ABHR solutions. Three of the compounding pharmacists indicated that ABHR production in their setting lack compliance to good compounding practice due to inadequate compounding room, quality control tests, manpower and equipment. Despite this, most study participants preferred the in-house ABHR products than the commercially available ones. Thus, training, regular monitoring and follow-up of the hospital compounding services can further build staff confidence.

Alcohol-Based Handrub Utilization Practice for COVID-19 Prevention Among Pharmacy Professionals in Ethiopian Public Hospitals: A Cross-Sectional Study.

PurposeRubbing the hands with alcohol-based handrub (ABHR) is globally recommended as the preferred approach to prevent healthcare-associated infections in most routine encounters with patients, except in cases handwashing with soap and water is advised. Inappropriate utilization of ABHR could have detrimental effects, most importantly during the coronavirus disease (COVID-19) pandemic, which include exposure of healthcare professionals to healthcare-associated infections and the development of resistant microorganisms. In a hospital setting, the utilization of ABHR among frontline healthcare workers including pharmacy professionals is low. Therefore, the purpose of this study was to explore the current practice of hand rubbing among pharmacy professionals in public hospitals of Addis Ababa during the pandemic of COVID-19.MethodsThe study was a cross-sectional study using a self-reported questionnaire conducted among pharmacy professionals in public hospitals found in Addis Ababa from 10th May to 9th June, 2020 to recognize ABHR utilization rate. Data were collected on a sample of 384 pharmacy professional by a self-administered questionnaire. Data analysis was done using software for the statistical package for social science version 25.0. To identify the significant predictors of ABHR utilization practice bivariable and multivariable logistic regressions were carried out. Crude odds ratio and adjusted odds ratio with 95% confidence interval were calculated to determine the predictors.ResultsOut of 384 participants, three hundred and four participants were included in the final analyses after the exclusion of incomplete responses. Female participants represented 41.4% of the study participants. More than half (58.9%) of the pharmacy professionals had sufficient knowledge on ABHR utilization for COVID-19 prevention. Similarly, 56.6% of pharmacy professionals had positive attitude towards ABHR for COVID-19 prevention. But only 35.9% of the study participants had good ABHR utilization practice.ConclusionDespite the modest level of knowledge and attitude towards ABHR, pharmacy professionals’ utilization practice of ABHR for COVID-19 prevention was found to be suboptimal. Provision of ABHR solutions through hospitals and increasing the awareness of pharmacy professionals on ABHR needs to be encouraged.

Increased Production of Alcohol-Based Hand Rub Solution in Response to COVID-19 and Fire Hazard Potential: Preparedness of Public Hospitals in Addis Ababa, Ethiopia.

BackgroundAccording to the World Health Organization (WHO), alcohol-based hand rubs (ABHRs) are regarded as the “gold standard” for hand disinfection in healthcare facilities. Local production of ABHRs in health facilities is recommended by WHO due to its availability and affordability reasons. However, fire hazard is a concern in health facilities during ABHRs production, storage, or use from dispensers.ObjectiveTo evaluate the preparedness of public hospitals found in Addis Ababa, Ethiopia towards potential fire hazards during ABHR production and storage practices.MethodsA cross-sectional observational study was applied. An assessment checklist was used for evaluating public hospitals’ measures taken for the potential fire hazards during ABHR production and storage practice. Statistical Package for Social Sciences (SPSS) version 23 was used for data entry and analysis.ResultsOut of the 13 public hospitals observed in the study, fire extinguishers were not available in more than half of the hospitals’ (7 hospitals) compounding premises. Also, 57.1% of the hospitals without fire extinguishers were manufacturing beyond the WHO 50 liters limit of ABHR solution at once under such unfavorable conditions. Moreover, ethanol and the oxidizing agent hydrogen peroxide were not stored separately in eight hospitals.ConclusionNone of the hospitals were found to be well prepared for the potential risk of fire associated with ABHR solution production and storage practice. Generally, the practices taken by the studied hospitals for preventing the fire risk and minimizing the damage if fire hazards occurred during ABHR production and storage were not satisfactory. On the safety and precautions measures taken for the risk of fire, Tikur Anbessa Specialized Hospital (TASH), Amanuel Mental Specialized Hospital (AMSH), and Eka Kotebe General Hospital (EKGH) showed a relatively better preparedness compared to others. ABHR solutions should be manufactured and stored in a way that limits the risk of ignition and follows standard fire safety measures.

What is new with hand hygiene?

Healthcare-associated infections (HAIs) challenge healthcare systems worldwide. As healthcare workers' hands are considered the main vector for transmission of pathogens, effective hand hygiene is the single most important action to prevent HAIs. We sought to highlight new developments and advances in hand hygiene. Hand hygiene compliance averages at 38%. A sustained increase of compliance with a subsequent decrease of HAIs may be achieved by national, systematic and rigorous education, and auditing programs. Periodically deployed self-operating hand hygiene surveillance systems coupled with personalized reminders could facilitate such efforts. Alcohol-based hand-rub (ABHR) solutions remain the hand hygiene gold standard, but are modified in texture and composition to better meet healthcare workers' preferences. Modifications of the hand hygiene procedure have been proposed targeting both time and technique of hand rub application. Reducing rub-time from 30 to 15 s and simplifying the technique to consist of three rather than six steps yielded encouraging results in terms of microbiological efficacy and higher compliance. Implementation and promotion of compliance are the major concerns of today's research on hand hygiene. Developments towards better surveillance and systematic education, improved ABHR formulation and streamlining of hand hygiene actions are paving the way ahead.

COVID casualty: Bilateral blindness due to ingestion of spurious sanitizer

Intentional ingestion of alcohol-based handrub (ABHR) or sanitizer solution is uncommon. The coronavirus disease-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 has led to lockdowns being put in place in many countries across the globe and resulted in a surge in ABHR usage to maintain hand hygiene. In this communication, we report the case of a 56-year-old male, a chronic alcoholic who presented during the lockdown period, with acute bilateral loss of vision following ingestion of ABHR. The handrub was found to be a nonstandardized sanitizer with no labels mentioning its constituents. Typically, the ingestion of ABHR solutions results in isopropanol or ethanol poisoning, both of which have low toxicity. Based on the clinical history and findings in our patient, a diagnosis of optic neuropathy due to accidental ingestion of sanitizer containing methyl alcohol as an unlisted ingredient was made. Our report underscores the need for strict guidelines, toxicovigilance, and surveillance systems to be in place to prevent such adulterated ABHRs from being commercially available.

Building Local Capacity in Hand-Rub Solution Production during the 2014-2016 Ebola Outbreak Disaster: The Case of Liberia and Guinea.

During the 2014-2015 Ebola outbreak in West Africa, the lack of infection prevention and control (IPC) measures in health care facilities amplified human-to-human transmission and contributed to the magnitude of this humanitarian disaster.Case ReportIn the summer of 2014, the Geneva University Hospitals (HUG; Geneva, Switzerland) conducted an IPC assessment and developed a project based on the local needs and their expertise with the support of the Swiss Agency for Development and Cooperation and the Humanitarian Aid Unit (SDC/HA; Bern, Switzerland). The project consisted of building local capacity in the production of alcohol-based hand-rub solution (ABHRS) based on the World Health Organization (WHO; Geneva, Switzerland) formula in non-Ebola health facilities at the peak of the outbreak in Liberia (Fall 2014) and during recovery in Guinea (September 2015) to promote safer care. Twenty-one pharmacists in Liberia and 22 in Guinea were trained and one years' worth of laboratory equipment, chemical products, containers for personal use, and bioethanol were delivered to 10 hospitals per country with more than 8,000 100 ml bottles of solution produced at the end of the project.DiscussionHand hygiene using hand-rub solution is a critical component of safer care, especially in health care settings lacking runnable water. Throughout the Ebola outbreak, it was a timely moment to promote hand-rub solution and to reinforce IPC measures in non-Ebola health facilities. During the project implementation, a substantial challenge was the unavailability of bioethanol in Liberia and Guinea. In the long run, sustainability of the production can become an issue as it depends heavily on the local government's financial and political commitment, the capacity to create an on-going demand for hand-rub solution in health facilities, the local purchase and replacement of the materials and chemical products, as well as the availability of continuous local partners' support. The project demonstrated that it was feasible to build local capacity in ABHRS production during an emergency and in limited-resource settings when materials and training are provided. Future programs in similar contexts should identify and address the factors of sustainability during the implementation phase and provide regular, long-term technical support.

Local production of alcohol based handrub solution (ABHS) in Liberia during the Ebola outbreak

The hands transmit the major part of the infection. In addition of a low level of awareness of the Infection Prevention and Control (IPC), the lack of availability of the ABHS is usual.

Skin side effects of chlorine solutions used for hand hygiene: a systematic review

Chlorine solutions (CS), mostly containing sodium hypochlorite (SH), have been widely used for hand hygiene (HH) in the West African countries affected by the Ebola outbreak due to unavailability of alcohol-based handrub solutions and soap, easiness of use and “fear” factors leading to (false) sense of safety given by using an easily available disinfectant. However, no HH guidelines recommend the use of CS and concerns have been raised about skin tolerability among users.

Alcohol Based Handrub versus Traditional Hand Scrub as Surgical Hand Disinfection in a Tertiary Eye Teaching Hospital in Iraq

Aim of the study: To compare alcohol-based handrub solutions and standard surgical scrub in preoperative hand disinfection.Methods: Single center, blinded, controlled study performed over a period of 4 weeks in the Ibn Al Haithem hospital. Surgeons, seniors and residents (with more than 2 years of experience) volunteered for inclusion in this study by taking their fingerprints on blood agar before and after hand disinfection.The two methods of disinfection were the following:A: Alcohol-based handrub with sterillium. The solution is applied to the hands for 1.5 min and then left to dry. The fingertips and thumb prints are then taken on blood agar plates.B: The hands are washed with soap and water using a gentle brush for 5 min and then left to dry.The fingertips and thumbprints are then taken on blood agar plates.Results: One hundred samples were collected twice. Fifty volunteers were in each group, and samples were collected before and after washing the hands.The mean reduction in colony counts was 104.6 (P 0.001) in the standard scrub group.Conclusion: In preoperative hand disinfection, alcohol-based handrub significantly reduces the bacterial colony counts compared with standard surgical scrub.

Assessment of exposure to ethanol vapors released during use of Alcohol-Based Hand Rubs by healthcare workers

Despite the increasing use of Alcohol-Based Hand Rub solutions, few studies have quantified the concentrations of inhaled ethanol. The aim of this study was to assess ethanol exposure during hygienic and surgical hand disinfection practices. Ethanol concentrations were measured at the nose level of a wooden dummy and human volunteers. Two systems were used in parallel to determine short-term ethanol vapor exposures: activated charcoal tubes followed by gas chromatography analysis and direct reading on a photoionization detector (PID). Exposure was assessed for 4 different sequences (N=10) reproducing hand rubs for simple surgery, nursing care, intensive care and surgical scrub. The ethanol concentrations measured were of a similar order between the dummy and volunteers. The concentrations obtained by PID were higher than the gas chromatography values for the simple care (45%) and nursing care (27%) sequences and reflected specific exposure peaks of ethanol, whereas ethanol concentrations were continuously high for intensive care (440 mg m(-3)) or surgical scrub (650 mg m(-3)). Ethanol concentrations were similar for these two exposure assessment methods and demonstrated a relationship between handled doses and inhaled doses. However, the ethanol vapors released during hand disinfection were safe for the healthcare workers.

Twenty years of antimicrobial resistance control programme in a regional multi hospital institution, with focus on emerging bacteria (VRE and CPE)

BackgroundAssistance Publique-Hôpitaux de Paris (APHP), the largest public health care institution in France (38 hospitals, 23,000 beds, serving 11.6 millions inhabitants) launched in 1993 a long term programme to control and survey multidrug resistant bacteria (MDR).FindingsAP-HP MDR programme consisted in successive waves of actions: bundle measures to survey and control cross transmission of MRSA and extended-spectrum betalactamase producing enterobacteria (ESBL) in 1993, large campaign to promote the use of alcohol-based hand rub solution (ABHRS) in 2001, specific strategy to quickly control the spread of emerging MDR (vancomycin resistant Enterococcus, VRE; carbapenemase producing enterobacteria, CPE) in 2006, large campaign to decrease antibiotics consumption in 2006.Following this programme, the ABHRS consumption dramatically increased, the antibiotic consumption decreased by 10%, the incidence of MRSA, including MRSA bacteraemia, decreased by 2/3, all VRE and CPE events were rapidly controlled. However, the incidence of ESBL, mainly Klebsiella pneumoniae and Escherichia coli, that remained low and stable until 2003 increased markedly afterwards, justifying adapting our programme in the future.ConclusionA sustained and coordinated strategy can lead to control multidrug resistant bacteria at the level of a large multihospital institution.

Economic Implications of the Dynamic Relationship between Antibiotic Use and Hospital-Acquired Infections

ObjectivesThe emergence and spread of antimicrobial resistance is still an unresolved problem worldwide. Recent evidence shows correlations between the volume of broad-spectrum antibiotics used in the hospital setting and the incidence of multidrug-resistant bacteria. According to this dynamic relationship, loss of antibiotic activity can be modeled as a negative externality of antibiotic consumption. MethodsThe present study proposes to present an economic model describing the probability of antibiotic treatment failure as a function of antimicrobial use and alcohol-based hand-rub use. Furthermore, the results of recently conducted time-series analyses and cost-of-illness studies are applied to the model to determine the externalities of antibiotic consumption and alcohol-based hand-rub use with respect to the costs of hospital-acquired infections. ResultsAccording to our calculations, the consumption of third-generation cephalosporins and fluoroquinolones is associated with the highest negative externalities (€143 and €101, respectively) because their use has been shown to be associated with most types of hospital-acquired infections. In contrast, the use of alcohol-based hand-rub solution for hand disinfection is associated with a positive externality of 41 cents per single disinfection of the hands. ConclusionsThe externalities presented in this work represent a possible application of cost-of-illness data to quantify the impact of antibiotic use on antimicrobial resistance. In addition, the results indicate that most economic research on the topic is biased in assuming the overall use of antibiotics to be responsible for the spread of antimicrobial resistance.

Prospective observational study to assess hand skin condition after application of alcohol-based hand rub solutions

The use of alcohol-based hand rub solutions (ABHRSs) in health care settings has been associated with increased hand hygiene compliance and reduced rates of nosocomial infection. Deterioration in hand skin condition leads to impaired barrier function, changes in skin flora, and increased bacterial shedding. Thus, poor skin condition can increase the risk of infection. This study evaluated the hand skin condition and dermal tolerance among health care workers (HCWs) after ABHRS application. The study group comprised 231 HCWs (34% nurses, 22% nurse assistants, and 15% hospital cleaners). The mean participant age was 40 years. Stratum corneum hydration and superficial sebum content and surface pH of the skin were measured on the back and palm of each participant's dominant hand before and after ABHRS use. A self-assessment questionnaire was administered to collect information about the participants, their skin problems, and their perception of the ABHRS. The study group was 83% females. Skin hydration at the 2 assessment sites was markedly increased after ABHRS use (P < .0001). The mean pH value did not change significantly on the back of the hand, but did change significantly on the palm (P = .012). The superficial sebum content decreased significantly on the palm (P < .0001), but not on the back of the hand. HCWs reported excellent or good skin tolerance of ABHRS in 73% of cases. ABHRSs are well tolerated and do not dry the skin. pH and superficial sebum values decreased slightly, but these decreases did not affect skin barrier function. Values remained within the physiological range.

Prospective observational study to assess hand skin condition after application of alcohol-based hand rubs solutions

Deterioration in skin condition leads to reduced barrier function, changes in skin flora, and increased bacterial shedding. Thus, poor skin condition can increase the risk of infection transmission. The aim of this study was to assess the hand skin condition and dermal tolerance, among Health Care Workers (HCWs) after application of Alcohol-based hand rub solution (ABHRS).

Control of a regional outbreak of vanA glycopeptide-resistant Enterococcus faecium, Eastern France, 2004–2009

At the end of 2004, an outbreak of glycopeptide-resistant enterococci (GRE) spread from the Nancy Teaching Hospital to more than 40 facilities in the Lorraine region. Because this outbreak appeared to be uninhibited, a regional task force was set up to organize and co-ordinate the management of the outbreak, visiting the affected facilities to publicize the existing recommendations and take stock of the problems encountered in the field. The task force then proposed control measures specific to the region. The proposed measures included promoting the use of alcohol-based hand-rub solutions, isolation measures, enhanced screening policies, cohorting GRE-colonized patients and contacts in special wards with dedicated staff where possible, or failing that, isolating them in single rooms with additional "contact" precautions, maintaining these precautions for GRE-colonized patients until a negative stool sample was obtained after antibiotic treatment (which is a more restrictive definition of "cleared" than usually employed), regional co-ordination of the follow-up of GRE-colonized patients with the weekly publication of a list of institutions that were or had been affected to allow isolation measures to be adopted as soon as known-GRE-colonized patient were readmitted. It was not possible to determine the efficacy of each individual measure on the course of the outbreak. Nevertheless, we observed that the number of new GRE-colonized patients started to decrease following their implementation. Ultimately, 1077 GRE colonizations were recorded in Lorraine, and the outbreak is now under control.

The role of general quality improvement measures in decreasing the burden of endemic MRSA in a medical–surgical intensive care unit

To determine whether any of several quality improvement interventions with none specifically targeting methicillin-resistant Staphylococcus aureus (MRSA) were associated with a decline in endemic MRSA prevalence in an intensive care unit (ICU) where active screening and contact isolation precautions for known MRSA colonised patients are not practised. Medical-surgical ICU with 2,000 admissions/year. 8.5-year retrospective time-series analysis. ICU re-location, antibiotic stewardship utilising computerised decision-support and infectious-diseases physician rounds, dedicated ICU infection control practitioners, alcohol-based hand rub solution (ABHRS). Regression modelling was used to evaluate trends in S. aureus prevalence density (monthly clinical isolates per 1,000 patient-days), antibiotic consumption, infection control consumables, ABHRS and their temporal relationship with MRSA prevalence. Methicillin-resistant S. aureus prevalence density decreased by 83% [95% confidence interval (CI) -68% to -91%, p < 0.001]. Rates of MRSA bacteraemia decreased 89% (95% CI -79% to -94%, p = 0.001) with no statistically significant change in methicillin-sensitive S. aureus bacteraemia. Hospital MRSA prevalence density decreased 17% (95% CI -5% to -27%, p = 0.005), suggesting that ICU was not shifting MRSA elsewhere. In ICU, broad-spectrum antibiotic use decreased by 26% (95% CI -12% to -38%, p = 0.008), coinciding with a decrease in MRSA, but time-series analysis did not show a significant association. On multivariate analysis, only ABHRS was significantly associated with a decrease in MRSA, but it was formally introduced late in the study period when MRSA was already in decline. General quality improvement measures were associated with a decrease in endemic MRSA in a high-risk setting without use of resource-intensive active surveillance and isolation practices.

Curbing Methicillin-Resistant Staphylococcus aureus in 38 French Hospitals Through a 15-Year Institutional Control Program

The Assistance Publique-Hôpitaux de Paris (AP-HP) institution administers 38 teaching hospitals (23 acute care and 15 rehabilitation and long-term care hospitals; total, 23 000 beds) scattered across Paris and surrounding suburbs in France. In the late 1980s, the proportion of methicillin resistance among clinical strains of Staphylococcus aureus (MRSA) reached approximately 40% at AP-HP. A program aimed at curbing the MRSA burden was launched in 1993, based on passive and active surveillance, barrier precautions, training, and feedback. This program, supported by the strong commitment of the institution, was reinforced in 2001 by a campaign promoting the use of alcohol-based hand-rub solutions. An observational study on MRSA rate was prospectively carried out from 1993 onwards. There was a significant progressive decrease in MRSA burden (-35%) from 1993 to 2007, whether recorded as the proportion (expressed as percentage) of MRSA among S aureus strains (41.0% down to 26.6% overall; 45.3% to 24.2% in blood cultures) or incidence of MRSA cases (0.86 down to 0.56 per 1000 hospital days). The MRSA burden decreased more markedly in intensive care units (-59%) than in surgical (-44%) and medical (-32%) wards. The use of ABHR solutions (in liters per 1000 hospital days) increased steadily from 2 L to 21 L (to 26 L in acute care hospitals and to 10 L in rehabilitation and long-term care hospitals) following the campaign. A sustained reduction of MRSA burden can be obtained at the scale of a large hospital institution with high endemic MRSA rates, providing that an intensive program is maintained for a long period.
