Boyce JM, Pittet D. Rinse, gel, and foam - is there any evidence for a difference in their effectiveness in preventing infections? Antimicrob Resist Infect Control 2024; 13:49. [PMID: 38730473 PMCID: PMC11084031 DOI: 10.1186/s13756-024-01405-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Accepted: 05/01/2024] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND Following publication of the 2009 World Health Organizations Guidelines for Hand Hygiene in Health Care, a debate has emerged regarding the relative antimicrobial efficacy of the different formats (rinse, gel, foam) of ABHRs and their ability to contribute to reduction of healthcare-associated infections (HAIs). METHODS Data regarding the in-vivo antimicrobial efficacy of ABHRs and other factors that likely affect their effectiveness in reducing HAIs were reviewed, and a comprehensive review of studies that reported the effectiveness of each of the three ABHR formats to improve hand hygiene compliance and reduce HAIs was conducted. RESULTS The amount of rubbing time it takes for hands to feel dry (dry time) is the major driver of ABHR antimicrobial efficacy. ABHR format is not a major factor, and several studies found that rinse, gel, and foam ABHRs have comparable in-vivo antimicrobial efficacy. Other factors that likely impact the ability of ABHRs to reduce transmission of healthcare-associated pathogens and HAIs include ABHR formulation, the volume applied to hands, aesthetic characteristics, skin tolerance, acceptance by healthcare personnel, and hand hygiene compliance rates. When accompanied by complementary strategies, promoting the use of each of the three ABHR formats has been associated with improvements in hand hygiene compliance rates. A review of 67 studies failed to identify an ABHR format that was significantly more effective in yielding statistically significant reductions in transmission of healthcare-associated pathogens or HAIs. CONCLUSIONS Current evidence is insufficient to definitively determine if one ABHR format is more effective in reducing transmission of healthcare-associated pathogens and HAIs. More rigorous studies such as multicenter randomized controlled trials comparing the different formats are needed to establish if one format is significantly more effective in reducing HAIs.

Abstract
Introduction Hand cleansing and disinfection is the most efficient method for reducing the rates of hospital-acquired infections which are a serious medical and economic problem. Striving to ensure the maximum safety of the therapeutic process, we decided to promote hand hygiene by implementing the educational program titled "Clean Care is a Safer Care". The occurrence of the COVID-19 pandemic affected the compliance with procedures related to the sanitary regime, including the frequency and accuracy of hand decontamination by medical personnel. Objective The objective of the study was to assess the usefulness of the educational program titled "Clean Care is a Safer Care" as a tool for increasing compliance with hand hygiene principles. Methods We monitored the compliance with the hygiene procedure before implementation of the program as well as during the hand hygiene campaign by means of direct observation as well as the disinfectant consumption rates. Results In the initial self-assessment survey, the hospital had scored 270/500 points (54%). Preliminary audit revealed the hygiene compliance rate at the level of 49%. After broad-scaled educational efforts, the semi-annual audit revealed an increase in hand hygiene compliance rate up to 81% (hospital average) while the final audit carried out after one year of campaigning revealed a compliance rate of 77%. The final score for the hospital increased to 435/500 points. Conclusions COVID-19 pandemic dramatically increased accuracy of proper hand hygiene procedures and consumption of disinfectant agents. The educational program has succeeded to reach its goal; however, long-term educational efforts are required to maintain and improve the quality of provided services.

Abstract
Pyrazolo[3,4-d]pyrimidines represent an important class of heterocyclic compounds well-known for their anticancer activity exerted by the inhibition of eukaryotic protein kinases. Recently, pyrazolo[3,4-d]pyrimidines have become increasingly attractive for their potential antimicrobial properties. Here, we explored the activity of a library of in-house pyrazolo[3,4-d]pyrimidines, targeting human protein kinases, against Staphylococcus aureus and Escherichia coli and their interaction with ampicillin and kanamycin, representing important classes of clinically used antibiotics. Our results represent a first step towards the potential application of dual active pyrazolo[3,4-d]pyrimidine kinase inhibitors in the prevention and treatment of bacterial infections in cancer patients.

Abstract
Estimates of the number of deaths from antimicrobial-resistant (AMR) infections are important data for clinicians and public health officials advocating for resources to prevent and treat these infections. The aims of this article are to describe the various approaches to calculating deaths from AMR infections, to compare the tally of deaths by each approach, and to explain how to interpret the results. Currently, none of the 3 methods employed by vital statistics systems to count deaths from specific causes (underlying cause of deaths, multiple causes of death, and avoidable deaths) count deaths from AMR infections. These deaths can be estimated by 4 approaches: case-fatality rate, infection-related mortality, and excess mortality using controls with antibiotic-susceptible infections or controls without antibiotic-resistant infections. When encountering discrepant estimates of AMR-related deaths, it is important to consider which method was used and whether it was the right method to answer the question being asked.

Abstract
BACKGROUND Health care facility-onset methicillin-resistant Staphylococcus aureus (HO-MRSA) colonization or infection is a major cause of health care-associated infection (HAI) worldwide. HAIs are preventable and considered a health care quality outcome indicator. A quality improvement project to eliminate HO-MRSA transmission was conducted in a tertiary care neonatal unit over a 9-month period, and sustainability data were monitored. The primary aim of this project was to achieve zero transmission of MRSA among all neonatal unit admissions, and secondary aims were to improve hand hygiene (HH) and environmental hygiene compliance to 100%. METHODS Existing inpatient admission processes, staff HH, and environmental hygiene practices were critically analyzed. Sequential interventions were implemented, including reinforcing staff awareness on infection control practices through regular education and updates, providing "just in time" feedback, ensuring easy availability of cleaning equipment, individualizing items for all patients, keeping personal belongings away from clinical areas, and revising admission work flow for ex-utero transferred babies from other hospitals. RESULTS The neonatal unit achieved zero MRSA transmission to previously noninfected and noncolonized patients over the 9-month period, and HH and environmental hygiene compliance improved from a preintervention median of 87.1% and 82.2%, respectively, to 100%, which has been sustained to date. CONCLUSIONS Intensive reinforcement of infection control practices, strict cohorting of ex-utero transfers, universal surveillance on admission, and improvement in HH and environmental hygiene compliance were key to infection prevention and control measures, resulting in elimination of MRSA transmission in our neonatal unit.

Abstract
SummaryObjectives: Use of Shewhart control charts in quality improvement (QI) initiatives is increasing. These charts are typically used in one or more phases of the Plan Do Study Act (PDSA) cycle to monitor summaries of process and outcome data, abstracted from clinical information systems, over time. We summarize methodological criteria of Shewhart control charts and investigate adherence of published QI studies to these criteria.Methods: We searched Medline, Embase and CINAHL for studies using Shewhart control charts in QI processes in direct patient care. We extracted methodological criteria for Shewhart control charts, and for the use of these charts in PDSA cycles, from textbooks and methodological literature.Results: We included 34 studies, presenting 64 control charts of which 40 control charts plotted two phases of the PDSA cycle. The criterion to use 10–35 data points in a control chart was least adhered to (48.4% non-adherence). Other criteria were: transformation of the data in case of a skewed distribution (43.7% non adherence), when comparing data from two phases of the PDSA cycle the Plan phase (the first phase) needs to be stable (40.0% non-adherence), using a maximum of four different rules to detect special cause variation (14.1% non-adherence), and setting control limits at three standard deviations from the mean (all control charts adhered).Conclusion: There is room for improvement with regard to the methodological construction of Shewhart control charts used in QI processes. Higher adherence to all methodological criteria will decrease the risk of incorrect conclusions about the process being monitored.

Abstract
OBJECTIVES Health care-associated infections (HAIs) pose a significant health care and cost burden. This study estimates annual HAI hospital costs in the US avoided through use of health care antiseptics (health care personnel hand washes and rubs; surgical hand scrubs and rubs; patient preoperative and preinjection skin preparations). METHODS A spreadsheet model was developed with base case inputs derived from the published literature, supplemented with assumptions when data were insufficient. Five HAIs of interest were identified: catheter-associated urinary tract infections, central line-associated bloodstream infections, gastrointestinal infections caused by Clostridium difficile, hospital- or ventilator-associated pneumonia, and surgical site infections. A national estimate of the annual potential lost benefits from elimination of these products is calculated based on the number of HAIs, the proportion of HAIs that are preventable, the proportion of preventable HAIs associated with health care antiseptics, and HAI hospital costs. The model is designed to be user friendly and to allow assumptions about prevention across all infections to vary or stay the same. Sensitivity analyses provide low- and high-end estimates of costs avoided. RESULTS Low- and high-end estimates of national, annual HAIs in hospitals avoided through use of health care antiseptics are 12,100 and 223,000, respectively, with associated hospital costs avoided of US$142 million and US$4.25 billion, respectively. CONCLUSION The model presents a novel approach to estimating the economic impact of health care antiseptic use for HAI avoidance, with the ability to vary model parameters to reflect specific scenarios. While not all HAIs are avoidable, removing or limiting access to an effective preventive tool would have a substantial impact on patient well-being and infection costs. HAI avoidance through use of health care antiseptics has a demonstrable and substantial impact on health care expenditures; the costs here are exclusive of administrative penalties or long-term outcomes for patients and caregivers such as lost productivity or indirect costs.

Abstract
BACKGROUND Statistical process control (SPC) is a visually appealing and statistically rigorous methodology very suitable to the analysis of emergency department (ED) operations. OBJECTIVE We demonstrate that the control chart is the primary tool of SPC; it is constructed by plotting data measuring the key quality indicators of operational processes in rationally ordered subgroups such as units of time. Control limits are calculated using formulas reflecting the variation in the data points from one another and from the mean. SPC allows managers to determine whether operational processes are controlled and predictable. We review why the moving range chart is most appropriate for use in the complex ED milieu, how to apply SPC to ED operations, and how to determine when performance improvement is needed. DISCUSSION SPC is an excellent tool for operational analysis and quality improvement for these reasons: 1) control charts make large data sets intuitively coherent by integrating statistical and visual descriptions; 2) SPC provides analysis of process stability and capability rather than simple comparison with a benchmark; 3) SPC allows distinction between special cause variation (signal), indicating an unstable process requiring action, and common cause variation (noise), reflecting a stable process; and 4) SPC keeps the focus of quality improvement on process rather than individual performance. CONCLUSION Because data have no meaning apart from their context, and every process generates information that can be used to improve it, we contend that SPC should be seriously considered for driving quality improvement in emergency medicine.

Abstract
The reasoning that improved hand hygiene compliance contributes to the prevention of health care-associated infections is widely accepted. It is also accepted that high hand hygiene alone cannot impact formidable risk factors, such as older age, immunosuppression, admission to the intensive care unit, longer length of stay, and indwelling devices. When hand hygiene interventions are concurrently undertaken with other routine or special preventive strategies, there is a potential for these concurrent strategies to confound the effect of the hand hygiene program. The result may be an overestimation of the hand hygiene intervention unless the design of the intervention or analysis controls the effect of the potential confounders. Other epidemiologic principles that may also impact the result of a hand hygiene program include failure to consider measurement error of the content of the hand hygiene program and the measurement error of compliance. Some epidemiological errors in hand hygiene programs aimed at reducing health care-associated infections are inherent and not easily controlled. Nevertheless, the inadvertent omission by authors to report these common epidemiological errors, including concurrent infection prevention strategies, suggests to readers that the effect of hand hygiene is greater than the sum of all infection prevention strategies. Worse still, this omission does not assist evidence-based practice.

Abstract
Monitoring hand hygiene compliance and providing healthcare workers with feedback regarding their performance are considered integral parts of multidisciplinary hand hygiene improvement programs. Observational surveys conducted by trained personnel are currently considered the “gold standard” method for establishing compliance rates, but they are time-consuming and have a number of shortcomings. Monitoring hand hygiene product consumption is less time-consuming and can provide useful information regarding the frequency of hand hygiene that can be used to give caregivers feedback. Electronic counting devices placed in hand hygiene product dispensers provide detailed information about hand hygiene frequency over time, by unit and during interventions. Electronic hand hygiene monitoring systems that utilize wireless systems to monitor room entry and exit of healthcare workers and their use of hand hygiene product dispensers can provide individual and unit-based data on compliance with the most common hand hygiene indications. Some systems include badges (tags) that can provide healthcare workers with real-time reminders to clean their hands upon entering and exiting patient rooms. Preliminary studies suggest that use of electronic monitoring systems is associated with increased hand hygiene compliance rates and that such systems may be acceptable to care givers. Although there are many questions remaining about the practicality, accuracy, cost, and long-term impact of electronic monitoring systems on compliance rates, they appear to have considerable promise for improving our efforts to monitor and improve hand hygiene practices among healthcare workers.

Abstract
Hand hygiene is acknowledged as the single most important measure to prevent nosocomial infections in the healthcare setting. Similarly, in non-clinical settings, hand hygiene is recognised as a key element in helping prevent the spread of infectious diseases. The aim of this study was to evaluate the efficacy of three different disinfectant hand sanitizers in reducing the burden of bacterial hand contamination in 60 healthy volunteers in a community setting, both before and after education about the correct use of hand sanitizers. The study is the first to evaluate the efficacy and ease of use of different formulations of hand rubs used by the general population. The products tested were: Sterillium (perfumed, liquid), desderman pure gel (odorless, gel) and Lavit (perfumed, spray). Sterillium and desderman are EN1500 (hygienic hand rub) certified products (available in pharmacy) and Lavit is non EN1500 certified and available in supermarkets. The two EN1500 certified products were found to be significantly superior in terms of reducing bacterial load. desderman pure gel, Sterillium and Lavit reduced the bacterial count to 6.4%, 8.2% and 28.0% respectively. After education in the correct use of each hand rub, the bacterial load was reduced even further, demonstrating the value of education in improving hand hygiene. Information about the testers' perceptions of the three sanitizers, together with their expectations of a hand sanitizer was obtained through a questionnaire. Efficacy, followed by skin compatibility were found to be the two most important attributes of a hand disinfectant in our target group.

Abstract
BACKGROUND The health care quality improvement movement is a complex enterprise. Implementing clinical quality initiatives requires attitude and behaviour change on the part of clinicians, but this has proven to be difficult. In an attempt to solve this kind of behavioural challenge, the theoretical domains framework (TDF) has been developed. The TDF consists of 14 domains from psychological and organisational theory said to influence behaviour change. No systematic research has been conducted into the ways in which clinical quality initiatives map on to the domains of the framework. We therefore conducted a qualitative mapping experiment to determine to what extent, and in what ways, the TDF is relevant to the implementation of clinical quality interventions. METHODS We conducted a thematic synthesis of the qualitative literature exploring clinicians' perceptions of various clinical quality interventions. We analysed and synthesised 50 studies in total, in five domains of clinical quality interventions: clinical quality interventions in general, structural interventions, audit-type interventions, interventions aimed at making practice more evidence-based, and risk management interventions. Data were analysed thematically, followed by synthesis of these themes into categories and concepts, which were then mapped to the domains of the TDF. RESULTS Our results suggest that the TDF is highly relevant to the implementation of clinical quality interventions. It can be used to map most, if not all, of the attitudinal and behavioural barriers and facilitators of uptake of clinical quality interventions. Each of these 14 domains appeared to be relevant to many different types of clinical quality interventions. One possible additional domain might relate to perceived trustworthiness of those instituting clinical quality interventions. CONCLUSIONS The TDF can be usefully applied to a wide range of clinical quality interventions. Because all 14 of the domains emerged as relevant, and we did not identify any obvious differences between different kinds of clinical quality interventions, our findings support an initially broad approach to identifying barriers and facilitators, followed by a "drilling down" to what is most contextually salient. In future, it may be possible to establish a model of clinical quality policy implementation using the TDF.

Abstract
BACKGROUND Hand hygiene has been acknowledged as the single most important measure to prevent nosocomial infections. Likewise, for non-clinical settings, hand hygiene is recognized as a key element to prevent the spread of infectious diseases, nevertheless poor compliance has been documented. The feasibility of hand hygiene interventions in open-community settings with adults is mostly unclear. AIM To investigate the acceptability and feasibility of a health campaign to promote hand hygiene with alcohol-based hand disinfectants at workplaces in a non-clinical setting. METHODS The surveys were conducted as part of a prospective, controlled intervention study with volunteers from the administration of the Ernst-Moritz-Arndt-University Greifswald, the municipality of Greifswald and the state of Mecklenburg-West Pomerania. Participants in the intervention group were provided with alcohol-based hand disinfection; the control group was unchanged. Eleven volunteers filled out an initial survey at the beginning of the intervention regarding demographic and health-related questions as well as questions about the type of work, and a survey after completion of the intervention to evaluate the study's impact on the participants' attitudes toward hand hygiene. Participants in the experimental group filled out a monthly questionnaire regarding their compliance with hand hygiene measures, feasibility of hand disinfection and possible side-effects. FINDINGS From 850 employees asked to participate, 134 were included in the study, and surveys from 129 participants (intervention: 64 vs control: 65) were accepted for analysis. Overall, datasets of 1230 person-months (79.46% of total possible follow-up surveys) were collected. Return rate and compliance remained high during the study period. Hand disinfection did not lead to skin problems in the majority of person-months. After the intervention, a majority of participants would favour a further use of hand disinfectants. CONCLUSION Campaigns that enforce the use of alcohol-based hand disinfectants can have a sustainable effect on the compliance with hand hygiene measures in non-clinical settings. Campaigns have been shown to be feasible and effective in the prevention of transmissible diseases, therefore employers should consider whether hand hygiene campaigns to introduce waterless hand rubs could be included in companies' health programmes.

Abstract
BACKGROUND Approximately 15 700 invasive methicillin-resistant Staphylococcus aureus (MRSA) infections occurred in US dialysis patients in 2010. Frequent hospital visits and prolonged bloodstream access, especially via central venous catheters (CVCs), are risk factors among hemodialysis patients. We describe the epidemiology of and recent trends in invasive MRSA infections among dialysis patients. METHODS We analyzed population-based data from 9 US metropolitan areas from 2005 to 2011. Cases were defined as MRSA isolated from a normally sterile body site in a surveillance area resident who received dialysis, and were classified as hospital-onset (HO; culture collected >3 days after hospital admission) or healthcare-associated community-onset (HACO; all others). Incidence was calculated using denominators from the US Renal Data System. Temporal trends in incidence and national estimates were calculated controlling for age, sex, and race. RESULTS From 2005 to 2011, 7489 cases were identified; 85.7% were HACO infections, and 93.2% were bloodstream infections. Incidence of invasive MRSA infections decreased from 6.5 to 4.2 per 100 dialysis patients (annual decrease, 7.3%) with annual decreases of 6.7% for HACO and 10.5% for HO cases. Among cases identified during 2009-2011, 70% of patients were hospitalized in the year prior to infection. Among hemodialysis cases, 60.4% of patients were dialyzed through a CVC. The 2011 national estimated number of MRSA infections was 15 169. CONCLUSIONS There has been a substantial decrease in invasive MRSA infection incidence among dialysis patients. Most cases had previous hospitalizations, suggesting that efforts to control MRSA in hospitals might have contributed to the declines. Infection prevention measures should include improved vascular access and CVC care.

Abstract
Background Consensus for methicillin-resistant Staphylococcus aureus (MRSA) control has still not been reached. We hypothesised that use of rapid MRSA detection followed by contact precautions and single room isolation would reduce MRSA acquisition. Methods This study was a pre-planned prospective interrupted time series comparing rapid PCR detection and use of long sleeved gowns and gloves (contact precautions) plus single room isolation or cohorting of MRSA colonised patients with a control group. The study took place in a medical-surgical intensive care unit of a tertiary adult hospital between May 21st 2007 and September 21st 2009. The primary outcome was the rate of MRSA acquisition. A segmented regression analysis was performed to determine the trend in MRSA acquisition rates before and after the intervention. Findings The rate of MRSA acquisition was 18.5 per 1000 at risk patient days in the control phase and 7.9 per 1000 at-risk patient days in the intervention phase, with an adjusted hazard ratio 0.39 (95% CI 0.24 to 0.62). Segmented regression analysis showed a decline in MRSA acquisition of 7% per month in the intervention phase, (95%CI 1.9% to 12.8% reduction) which was a significant change in slope compared with the control phase. Secondary analysis found prior exposure to anaerobically active antibiotics and colonization pressure were associated with increased acquisition risk. Conclusion Contact precautions with single room isolation or cohorting were associated with a 60% reduction in MRSA acquisition. While this study was a quasi-experimental design, many measures were taken to strengthen the study, such as accounting for differences in colonisation pressure, hand hygiene compliance and individual risk factors across the groups, and confining the study to one centre to reduce variation in transmission. Use of two research nurses may limit its generalisability to units in which this level of support is available.

Abstract
Hand hygiene is regarded as the most effective means of preventing healthcare associated infection. However, systematic reviews provide limited evidence of effectiveness, a finding that is attributed to the poor quality of research designs, dubious outcome measures and flawed approaches to audit. The ability of interventions to improve hand hygiene compliance has not previously been questioned. This review categorises the types of interventions used to promote hand hygiene and discusses their plausibility, taking selected examples from previous systematic searches. Opinion leaders have emphasised the need for interventions to be underpinned by theory. This is an ambitious endeavour for infection control personnel based in National Health Service trusts. However, it is possible to offer pragmatic suggestions to promote compliance. Initiatives are most likely to be successful if needs analysis is undertaken at the outset to address local barriers and identify enablers to compliance, and if interventions are clearly justified by existing evidence, customised according to occupational group, consider health workers’ needs and preferences for training and updating, and avoid punishment.

Abstract
BACKGROUND The objective of the study was to investigate the effectiveness of non-pharmacological interventions in preventing cases of influenza requiring hospitalization. METHODS We performed a multicenter case-control study in 36 hospitals, in 2010 in Spain. Hospitalized influenza cases confirmed by reverse-transcription polymerase chain reaction and three matched controls (two hospital and one community control) per case were selected. The use of non-pharmacological measures seven days before the onset of symptoms (frequency of hand washing, use of alcohol-based hand sanitizers and handwashing after touching contaminated surfaces) was collected. RESULTS We studied 813 cases hospitalized for influenza and 2274 controls. The frequency of hand washing 5-10 times (adjusted odds ratio [aOR]=0.65) and >10 times (aOR=0.59) and handwashing after contact with contaminated surfaces (aOR=0.65) were protective factors and were dose-responsive (p<0.001). Alcohol-based hand sanitizers were associated with marginal benefits (aOR=0.82). CONCLUSIONS Frequent handwashing should be recommended to prevent influenza cases requiring hospitalization.

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

Abstract
BACKGROUND Catheter-associated bloodstream infections (CA-BSIs) are associated with increased morbidity and mortality. Previous investigations have reported outbreaks of CA-BSI temporally associated with the use of needleless connector valves or similar devices. METHODS We observed an unexpected increase in the rate of CA-BSI at our institution during August 2009. We used statistical process control and quality improvement methodology to identify the factor(s) associated with this increased rate of CA-BSI. RESULTS We reviewed the overall hospital Shewhart U chart for CA-BSI, which indicated special cause variation with an unexpected cluster (6/9; 67%) of CA-BSIs localized to the oncology ward and the bone marrow transplant unit. An event-cause analysis review showed that 5 of these 9 infections were caused by Staphylococcus aureus. We discovered that the Spiros Closed Male Connector (ICU Medical, San Clemente, CA) had been introduced in these 2 units around the same time as the cluster of infections occurred. Based on this information, we discontinued the use of this device, and the CA-BSI rate and distribution of causative microorganisms returned to previous baseline values. CONCLUSION This case study highlights the utility of statistical process control in the surveillance and investigation of CA-BSI.

Abstract
BACKGROUND The infection rates of multidrug-resistant organisms (MDRO) are increasing in Canada and the United States. The prevention and control of MDRO infections remain an important issue in acute care hospitals. Although comprehensive infection prevention and control programs have been recommended, there is little evidence to date of their effectiveness or of what aspects are most important. OBJECTIVES Our objectives were to review and critique the literature on the relationship between an MDRO infection and control program and MDRO rates in acute care hospitals. METHODS Studies including original research published between January 1, 1998, and May 14, 2009, were identified through MEDLINE, CINAHL, EMBASE, PUBMED, The Cochrane Library, and expert consultation. A comprehensive search strategy was developed with a librarian to find studies that covered the main subject areas of this integrative review. RESULTS Of the 1,382 papers retrieved, 47 were reviewed, and 32 studies met the inclusion criteria. The interventions in the included studies were assessed using the tier 1/tier 2 framework. A total of 18 (56.25%) studies had an administrative measure as an intervention; 20 (62.5%) studies had education and training of health care personnel; 8 (25.0%) studies had judicious use of antimicrobial agents; 17 (53.1%) studies used surveillance; 24 (75.0%) studies had infection control precautions to prevent transmission; 7 studies (21.9%) introduced environmental measures; and 9 (28.1%) studies used patient decolonization. Although all the 32 studies were quasiexperimental studies, only 2 (5.9%) studies provided sample size calculations, and only 5 studies reported confounding factors. Whereas 27 used an interrupted time series design and 2 were controlled pre- and post-intervention designs, 3 were pre- and post-intervention without control groups. CONCLUSION This integrative review demonstrated that the evidence of the relationship between MDRO infection prevention and control programs and the rates of MDRO is weak. Although major methodologic weaknesses exist in the published literature making it not possible to exclude other plausible explanations for the reduction of the acquisition of MDRO, the overall evidence does support the use of multiple interventions to reduce the rates of MDRO in acute care hospitals. Whereas it is unclear which bundles of interventions are effective, there is a clear suggestion that multiple simultaneous interventions can be effective in reducing MDRO infections. In addition, despite the limitations of interrupted time series, multiple studies employing active surveillance cultures were associated with reduced MDRO infections. Future individual reports of outbreaks and intervention studies should be written in a standardized manner using the recommended Outbreak Reports and Intervention Studies of Nosocomial Infection (ORION) guidelines. Further research is needed on the proposed tier 1/tier 2 framework clearly indicating all the interventions implemented.

Abstract
Infections in skilled nursing facilities (SNFs) are common and result in frequent hospital transfers, functional decline, and death. Colonization with multidrug-resistant organisms (MDROs) - including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and multidrug-resistant gram-negative bacilli (R-GNB) - is also increasingly prevalent in SNFs. Antimicrobial resistance among common bacteria can adversely affect clinical outcomes and increase health care costs. Recognizing a need for action, legislators, policy-makers, and consumer groups are advocating for surveillance cultures to identify asymptomatic patients with MDROs, particularly MRSA in hospitals and SNFs. Implementing this policy for all SNF residents may be costly, impractical, and ineffective. Such a policy may result in a large increase in the number of SNF residents placed in isolation precautions with the potential for reduced attention by health care workers, isolation, and functional decline. Detection of colonization and subsequent attempts to eradicate selected MDROs can also lead to more strains with drug resistance. We propose an alternative strategy that uses a focused multicomponent bundle approach that targets residents at a higher risk of colonization and infection with MDROs, specifically those who have an indwelling device. If this strategy is effective, similar strategies can be studied and implemented for other high-risk groups.

Abstract
Research on hygiene has been relatively limited in the current era of rigorous observational studies and clinical trials. We set out to investigate the perception and practices of genital hygiene among fishermen working on the beaches along Lake Victoria, targeted for a topical male microbicide hygiene intervention. We conducted 12 focus group discussions involving fishermen (n = 130), recording the discussions in Dholuo (the local language) and transcribing them verbatim before translating into English. Transcripts were double-coded and analysed using constant comparative analysis. Despite easy access to lake water and recognition of a link that may exist between poor genital hygiene and the risk of penile infection and poor sexual relationships, few fishermen regularly washed their genitalia due to fear/embarrassment from cleaning their genitalia in public, traditional Luo beliefs such as that washing with soap would reduce the fish catch, lack of time because of their busy schedules, laziness and lack of responsibility, and excessive consumption of alcohol and illicit drugs. Hygiene practices of the fishermen were poor and could contribute to genital infections including sexually transmitted infections. Given the fishermen's poor genital hygiene practices, they may benefit from hygiene intervention, including that provided by penile microbicides, which can be applied in the privacy of their bedrooms.

Abstract
BACKGROUND Health care-associated infection is a major cause of morbidity and mortality. Hand hygiene is regarded as an effective preventive measure. OBJECTIVES To update the review done in 2007, to assess the short and longer-term success of strategies to improve hand hygiene compliance and to determine whether a sustained increase in hand hygiene compliance can reduce rates of health care-associated infection. SEARCH STRATEGY We conducted electronic searches of: the Cochrane Central Register of Controlled Trials; the Cochrane Effective Practice and Organisation of Care Group specialised register of trials; MEDLINE; PubMed; EMBASE; CINAHL; and the BNI. Originally searched to July 2006, for the update databases were searched from August 2006 until November 2009. SELECTION CRITERIA Randomised controlled trials, controlled clinical trials, controlled before and after studies, and interrupted time series analyses meeting explicit entry and quality criteria used by the Cochrane Effective Practice and Organisation of Care Group were eligible for inclusion. Studies reporting indicators of hand hygiene compliance and proxy indicators such as product use were considered. Self-reported data were not considered a valid measure of compliance. Studies to promote hand hygiene compliance as part of a care bundle approach were included, providing data relating specifically to hand hygiene were presented separately. Studies were excluded if hand hygiene was assessed in simulations, non-clinical settings or the operating theatre setting. DATA COLLECTION AND ANALYSIS Two reviewers independently extracted data and assessed data quality. MAIN RESULTS Four studies met the criteria for the review: two from the original review and two from the update. Two studies evaluated simple education initiatives, one using a randomized clinical trial design and the other a controlled before and after design. Both measured hand hygiene compliance by direct observation. The other two studies were both interrupted times series studies. One study presented three separate interventions within the same paper: simple substitutions of product and two multifaceted campaigns, one of which included involving practitioners in making decisions about choice of hand hygiene products and the components of the hand hygiene program. The other study also presented two separate multifaceted campaigns, one of which involved application of social marketing theory. In these two studies follow-up data collection continued beyond twelve months, and a proxy measure of hand hygiene compliance (product use) was recorded. Microbiological data were recorded in one study. Hand hygiene compliance increased for one of the studies where it was measured by direct observation, but the results from the other study were not conclusive. Product use increased in the two studies in which it was reported, with inconsistent results reported for one initiative. MRSA incidence decreased in the one study reporting microbiological data. AUTHORS' CONCLUSIONS The quality of intervention studies intended to increase hand hygiene compliance remains disappointing. Although multifaceted campaigns with social marketing or staff involvement appear to have an effect, there is insufficient evidence to draw a firm conclusion. There remains an urgent need to undertake methodologically robust research to explore the effectiveness of soundly designed and implemented interventions to increase hand hygiene compliance.

Sequential introduction of single room isolation and hand hygiene campaign in the control of methicillin-resistant Staphylococcus aureus in intensive care unit. BMC Infect Dis 2010; 10:263. [PMID: 20822509 PMCID: PMC2944349 DOI: 10.1186/1471-2334-10-263] [Citation(s) in RCA: 49] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2010] [Accepted: 09/07/2010] [Indexed: 02/04/2023] Open
Abstract
Background After renovation of the adult intensive care unit (ICU) with installation of ten single rooms, an enhanced infection control program was conducted to control the spread of methicillin-resistant Staphylococcus aureus (MRSA) in our hospital. Methods Since the ICU renovation, all patients colonized or infected with MRSA were nursed in single rooms with contact precautions. The incidence of MRSA infection in the ICU was monitored during 3 different phases: the baseline period (phase 1); after ICU renovation (phase 2) and after implementation of a hand hygiene campaign with alcohol-based hand rub (phase 3). Patients infected with extended spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella species were chosen as controls because they were managed in open cubicles with standard precautions. Results Without a major change in bed occupancy rate, nursing workforce, or the protocol of environmental cleansing throughout the study period, a stepwise reduction in ICU onset nonbacteraemic MRSA infection was observed: from 3.54 (phase 1) to 2.26 (phase 2, p = 0.042) and 1.02 (phase 3, p = 0.006) per 1000-patient-days. ICU onset bacteraemic MRSA infection was significantly reduced from 1.94 (phase 1) to 0.9 (phase 2, p = 0.005) and 0.28 (phase 3, p = 0.021) per 1000-patient-days. Infection due to ESBL-producing organisms did not show a corresponding reduction. The usage density of broad-spectrum antibiotics and fluoroquinolones increased from phase 1 to 3. However a significant trend improvement of ICU onset MRSA infection by segmented regression analysis can only be demonstrated when comparison was made before and after the severe acute respiratory syndrome (SARS) epidemic. This suggests that the deaths of fellow healthcare workers from an occupational acquired infection had an overwhelming effect on their compliance with infection control measures. Conclusion Provision of single room isolation facilities and promotion of hand hygiene practice are important. However compliance with infection control measures relies largely on a personal commitment, which may increase when personal safety is threatened.

Abstract
Background The economical impact of absenteeism and reduced productivity due to acute infectious respiratory and gastrointestinal disease is normally not in the focus of surveillance systems and may therefore be underestimated. However, large community studies in Europe and USA have shown that communicable diseases have a great impact on morbidity and lead to millions of lost days at work, school and university each year. Hand disinfection is acknowledged as key element for infection control, but its effect in open, work place settings is unclear. Methods Our study involved a prospective, controlled, intervention-control group design to assess the epidemiological and economical impact of alcohol-based hand disinfectants use at work place. Volunteers in public administrations in the municipality of the city of Greifswald were randomized in two groups. Participants in the intervention group were provided with alcoholic hand disinfection, the control group was unchanged. Respiratory and gastrointestinal symptoms and days of work were recorded based on a monthly questionnaire over one year. On the whole, 1230 person months were evaluated. Results Hand disinfection reduced the number of episodes of illness for the majority of the registered symptoms. This effect became statistically significant for common cold (OR = 0.35 [0.17 - 0.71], p = 0.003), fever (OR = 0.38 [0.14-0.99], p = 0.035) and coughing (OR = 0.45 [0.22 - 0.91], p = 0.02). Participants in the intervention group reported less days ill for most symptoms assessed, e.g. colds (2.07 vs. 2.78%, p = 0.008), fever (0.25 vs. 0.31%, p = 0.037) and cough (1.85 vs. 2.00%, p = 0.024). For diarrhoea, the odds ratio for being absent became statistically significant too (0.11 (CI 0.01 - 0.93). Conclusion Hand disinfection can easily be introduced and maintained outside clinical settings as part of the daily hand hygiene. Therefore it appears as an interesting, cost-efficient method within the scope of company health support programmes. Trial registration number ISRCTN96340690

Abstract
PURPOSE 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. SETTING Medical-surgical ICU with 2,000 admissions/year. DESIGN 8.5-year retrospective time-series analysis. INTERVENTIONS 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). METHOD 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. RESULTS 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. CONCLUSION 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.

Abstract
OBJECTIVE To assess the feasibility and effectiveness of the World Health Organization hand hygiene improvement strategy in a low-income African country. DESIGN A before-and-after study from December 2006 through June 2008, with a 6-month baseline evaluation period and a follow-up period of 8 months from the beginning of the intervention. SETTING University Hospital, Bamako, Mali. Participants. Two hundred twenty-four healthcare workers. METHODS The intervention consisted of introducing a locally produced, alcohol-based handrub; monitoring hand hygiene compliance; providing performance feedback; educating staff; posting reminders in the workplace; and promoting an institutional safety climate according to the World Health Organization multimodal hand hygiene improvement strategy. Hand hygiene infrastructure, compliance, healthcare workers' knowledge and perceptions, and handrub consumption were evaluated at baseline and at follow-up. RESULTS Severe deficiencies in the infrastructure for hand hygiene were identified before the intervention. Local handrub production and quality control proved to be feasible, affordable, and satisfactory. At follow-up, handrubbing was the quasi-exclusive hand hygiene technique (93.3%). Compliance increased from 8.0% at baseline to 21.8% at follow-up (P < .001). Improvement was observed across all professional categories and medical specialities and was independently associated with the intervention (odds ratio, 2.50; 95% confidence interval, 1.8-3.5). Knowledge enhanced significantly (P < .05), and perception surveys showed a high appreciation of each strategy component by staff. CONCLUSIONS Multimodal hand hygiene promotion is feasible and effective in a low-income country. Access to handrub was critical for its success. These findings motivated the government of Mali to expand the intervention nationwide. This experience represents a significant advancement for patient safety in developing countries.

Abstract
Many countries have national guidelines for the prevention and control of methicillin-resistant Staphylococcus aureus (MRSA) that are similar in approach. The evidence base for many recommendations is variable, and often, in the drafting of such guidelines, the evidence is either not analysed or not specifically reviewed. Guidelines usually recommend screening and early detection, hand hygiene, patient isolation or cohorting, and decolonization. Although many components of a prevention and control programme appear to be self-evident, e.g. patient isolation, the scientific base underpinning these is poor, and scientifically rigorous studies are required. Nonetheless, where measures, based on what evidence there is and on common sense, are implemented, and where the necessary resources are provided, MRSA can be controlled. In The Netherlands and in other low-prevalence countries, these measures have largely kept healthcare facilities MRSA-free. In MRSA-endemic countries, such as Spain and Ireland, national guidelines are often not fully implemented, owing to apparently inadequate resources or a lack of will. However, recent studies from France and Australia demonstrate what is possible in high-prevalence countries when best practice is effectively implemented, with potentially major benefits for patients, the respective health services, and society.

Abstract
There are few more compelling questions in clinical microbiology today than the issue of whether or not to screen for the presence of methicillin-resistant Staphylococcus aureus (MRSA), with the results being used to institute infection control interventions aimed at preventing transmission of MRSA in health care environments. Numerous different matters must be addressed when considering a screening program. Who is to be screened, what method is to be employed to detect MRSA, and what sites should be sampled? When and how often should the screening be performed? Who is going to pay for the screening, and, finally and perhaps most importantly, how are screening results to be communicated to health care providers and what kind of interventions are best undertaken based on the results? Numerous governmental agencies have mandated MRSA screening programs, and yet several authorities in infection control organizations have questioned the appropriateness of mandated screening. In this Point-Counterpoint feature, Dr. Lance Peterson of Evanston Hospital (Evanston, IL) offers his perspective on why screening for MRSA is to be encouraged. Dr. Daniel Diekema of the University of Iowa Carver College of Medicine (Iowa City, IA) offers an opposing view.

Abstract
Health care-associated infections (HAIs) are a major clinical and economic problem in Australian hospitals, and a significant proportion are preventable. HAIs are the result of complex environmental, microbiological, pathological, behavioural and organisational factors, and prevention requires a multifaceted ("bundled") approach, including appropriate policies, educational programs for health care workers, and adequate resources to implement them effectively. Failure to protect patients from avoidable harm, including HAIs, has significant ethical implications; it often reflects both organisational systems failure and non-compliance of health care workers with evidence-based policies, including hand hygiene. If implemented with appropriate safeguards, infection control "bundles" that include sanctions for poor compliance with hand hygiene and other infection control policies, will achieve sustained improvements where previous approaches have failed.

Abstract
Hand washing was rightly considered a measure of personal hygiene for centuries. Today there is enough scientific evidence showing that a simple and inexpensive measure can help significantly reduce clinical infections. In spite of this, published studies show that hand hygiene only takes place between 15% and 50% of the instances in which it should be done. In order to support countries in setting priorities to deal with infections related to health care, the World Health Organization has developed a campaign to improve compliance with hand hygiene. Fundamental elements of the campaign include staff training, change of habits, motivating health professionals, and enabling access to effective products at the point of patient care. At institutional level, healthcare managers need to make a firm commitment, and make hand hygiene one of the quality assurance objectives of their organisations.

Abstract
OBJECTIVE To determine the impact of antibiotic consumption and alcohol-based hand disinfection on the incidences of nosocomial methicillin-resistant Staphylococcus aureus (MRSA) infection and Clostridium difficile infection (CDI). METHODS Two multivariate time-series analyses were performed that used as dependent variables the monthly incidences of nosocomial MRSA infection and CDI at the Freiburg University Medical Center during the period January 2003 through October 2007. The volume of alcohol-based hand rub solution used per month was quantified in liters per 1,000 patient-days. Antibiotic consumption was calculated in terms of the number of defined daily doses per 1,000 patient-days per month. RESULTS The use of alcohol-based hand rub was found to have a significant impact on the incidence of nosocomial MRSA infection (P< .001). The multivariate analysis (R2=0.66) showed that a higher volume of use of alcohol-based hand rub was associated with a lower incidence of nosocomial MRSA infection. Conversely, a higher level of consumption of selected antimicrobial agents was associated with a higher incidence of nosocomial MRSA infection. This analysis showed this relationship was the same for the use of second-generation cephalosporins (P= .023), third-generation cephalosporins (P= .05), fluoroquinolones (P= .01), and lincosamides (P= .05). The multivariate analysis (R2=0.55) showed that a higher level of consumption of third-generation cephalosporins (P= .008), fluoroquinolones (P= .084), and/or macrolides (P= .007) was associated with a higher incidence of CDI. A correlation with use of alcohol-based hand rub was not detected. CONCLUSION In 2 multivariate time-series analyses, we were able to show the impact of hand hygiene and antibiotic use on the incidence of nosocomial MRSA infection, but we found no association between hand hygiene and incidence of CDI.

Abstract
OBJECTIVE To implement a system for monitoring of rare events based on statistical process control charts. DESIGN Statistical process control plotting by g chart of clinical microbiology laboratory data. SETTING Primary and secondary care Norwegian hospital with a 9-bed intensive care unit. RESULTS During the winter of 2001-2002 in Norway, there was a national monoclonal nosocomial outbreak of Pseudomonas aeruginosa infection mainly affecting patients in intensive care units. In the present work, we demonstrate how the use of SPC at one of the affected hospitals would have detected this outbreak several weeks before the alert from the Norwegian National Public Health Institute (NIPH). By plotting the monthly incidence rate of P. aeruginosa infection (with a c chart), we found that the hospital would have been alerted in February; by plotting the number of days between events (with a g chart), we found that the hospital would have detected a process already out of control in early January 2002. Not until 9 weeks later (ie, mid-March) did the NIPH declare the P. aeruginosa outbreak to be national, and a commercially produced mouth swab contaminated during the manufacturing process was found to be the source. CONCLUSION The plotting of rare events, such as an outbreak of nosocomial infection, with a g chart may be used for early detection of a process out of control.

Abstract
BACKGROUND Hand hygiene (HH) compliance among health care workers (HCWs) has been historically low and hampered by poor surveillance methods. This study evaluated the use of an electronic device to measure and impact HH compliance. METHODS The study is a prospective, interventional study in a 30-bed academic medical center hematology unit. Phase I of the study monitored baseline HH compliance, and phase II monitored HH compliance using automatic alerts. The primary outcome measure was HH compliance, and the secondary end point was nosocomial transmission of vancomycin-resistant Enterococcus (VRE). RESULTS Eight thousand two hundred thirty-five HH opportunities were measured during the study, with HH compliance improvement from 36.3% at baseline to 70.1% during phase II. The use of audible alerts improved HH compliance for both the day shift (odds ratio [OR], 3.6) and the night shift (OR, 5.9), as well as across rooms with higher HCW traffic (OR, 1.6) and lower HCW traffic (OR, 3.2). CONCLUSION Electronic devices can effectively monitor HH compliance among HCWs and facilitate improved adherence to guidelines. Electronic devices improve HH compliance regardless of time of day or room location. The development of innovative devices to improve HH is required to validate the long-term implications of this methodology.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) is prevalent in many hospitals, but many of its most serious clinical manifestations, such as bloodstream infection and ventilator-associated pneumonia, are seen in the intensive care unit (ICU). Many interventions to prevent and control MRSA were initially pioneered in the ICU and subsequently extended to the rest of the hospital. Recent studies confirm how many of these are effective. Active surveillance reveals higher numbers of cases when compared with the sole use of clinical specimens to identify MRSA-positive patients. Although one recent study from the UK has suggested that isolation has no impact on MRSA transmission in the ICU, current recommendations include isolation or cohorting, combined with decolonisation (e.g., mupirocin to the nose and chlorhexidine baths) as major control measures. However, the excessive use of mupirocin for nasal MRSA decolonisation leads to resistance. Improved compliance with hand hygiene recommendations and better antibiotic stewardship are also important. Rapid diagnosis such as PCR may utilise isolation facilities more effectively by identifying MRSA patients earlier. However, all these measures must be combined with adequate numbers of staff and suitable space and facilities, e.g., single rooms, to be maximally effective. Finally, while much can be done within the ICU itself, MRSA in the ICU often reflects the difficulties elsewhere in the acute hospital and the health service generally, in terms of the control and prevention of healthcare-associated infection.
