Impact of the ventilator bundle on ventilator-associated pneumonia in intensive care unit.

OBJECTIVE: The ventilator bundle is being promoted to prevent adverse events in ventilated patients including ventilator-associated pneumonia (VAP). We aimed to: (i) examine adoption of the ventilator bundle elements; (ii) determine effectiveness of individual elements and setting characteristics in reducing VAP; (iii) determine effectiveness of two infection-specific elements on reducing VAP; and, (iv) assess crossover effects of complying with VAP elements on central line-associated bloodstream infections. DESIGN: Cross-sectional survey. SETTING: Four hundred and fifteen ICUs from 250 US hospitals. PARTICIPANTS: Managers/directors of infection prevention and control departments. INTERVENTIONS: Adoption and compliance with ventilator bundle elements. MAIN OUTCOME MEASURES: VAP rates. RESULTS: The mean VAP rate was 2.7/1000 ventilator days. Two-thirds (n = 284) reported presence of the full ventilator bundle policy. However, only 66% (n = 188/284) monitored implementation; of those, 39% (n = 73/188) reported high compliance. Only when an intensive care unit (ICU) had a policy, monitored compliance and achieved high compliance were VAP rates lower. Compliance with individual elements or just one of two infection-related element had no impact on VAP (ß = -0.79, P= 0.15). There was an association between complying with two infection elements and lower rates (ß = -1.81, P< 0.01). There were no crossover effects. Presence of a full-time hospital epidemiologist (HE) was significantly associated with lower VAP rates (ß = -3.62, P< 0.01). CONCLUSIONS: The ventilator bundle was frequently present but not well implemented. Individual elements did not appear effective; strict compliance with infection elements was needed. Efforts to prevent VAP may be successful in settings of high levels of compliance with all infection-specific elements and in settings with full-time HEs.

Relationship between systems-level factors and hand hygiene adherence.

This study was a cross-sectional descriptive survey of acute care hospitals in California to describe staff hand hygiene compliance and related predictors and explore the relationship between hand hygiene adherence and health care-associated infections. Although there was a relatively small sample size, institutions with morning huddles reported a significantly higher proportion of 95% or more hand hygiene compliance. Huddles are an organizational tool to improve teamwork and communication and may offer promise to influence hand hygiene adherence.

California hospitals response to state and federal policies related to health care-associated infections.

In October 2008, the Centers for Medicare and Medicaid Services (CMS) denied payment for ten selected health care-associated infections (HAI). In January 2009, California enacted mandatory reporting of infection prevention processes and HAI rates. This longitudinal mixed-methods study examined the impact of federal and state policy changes on California hospitals. Data on structures, processes, and outcomes of care were collected pre- and post-policy changes. In-depth interviews with hospital personnel were performed after policy implementation. More than 200 hospitals participated with 25 personnel interviewed. We found significant increases in adoption of and adherence to evidence-based practices and decreased HAI rates (p < .05). Infection preventionists (IP) spent more time on surveillance and in their offices and less time on education and in other locations (p < .05). Qualitative data confirmed mandatory reporting had intended and unintended consequences and highlighted the importance of technology and organizational climate in preventing infections and the changing IPs' role. This is especially relevant because the California Department of Public Health has since mandated hospitals to report data on 29 different for surgical site infections and a lawsuit has been filed to delay the implementation of these requirements.

Exploring infection prevention: policy implications from a qualitative study.

Health care-associated infections (HAIs) are common and costly patient safety problems that are largely preventable. As a result, numerous policy changes have recently taken place including mandatory reporting and lack of reimbursement for HAIs. A qualitative approach was used to obtain dense description and gain insights about the current practice of infection prevention in California. Twenty-three in-depth, semistructured interviews were conducted at six acute care hospitals. Content analysis revealed 4 major interconnected themes: (a) impacts of mandatory reporting; (b) impacts of technology on HAI surveillance; (c) infection preventionists' role expansion; and (d) impacts of organizational climate. Personnel reported that interdisciplinary collaboration was a major facilitator for implementing effective infection prevention, and organizational climate promoting a shared accountability is urgently needed. Mandatory reporting requirements are having both intended and unintended consequences on HAI prevention. More research is needed to measure the long-term effects of these important changes in policy.

Changes in the institutional review board submission process for multicenter research over 6 years.

Although collaborative research across sites is essential to increase the statistical power and generalizability of research findings, the need to undergo multiple institutional review board (IRB) reviews is a challenge. The purposes of this paper are to describe changes in the IRB submission process in 2 national multisite studies before and after the implementation of the Health Information Portability and Accountability Act (HIPAA) Privacy rule (2002 and 2008) and to discuss implications for policy and practice related to human subjects research. In the second study, there was a shorter mean approval time and reduced variability in the decision about the level of review, the mean number of pages per application doubled, and an increased proportion of IRBs required conflict of interest and data use agreements. Possible approaches to further enhance the efficiency and streamlining of the research review process are suggested.

Mutations in the Drosophila mitochondrial tRNA amidotransferase, bene/gatA, cause growth defects in mitotic and endoreplicating tissues.

Rapid larval growth is essential in the development of most metazoans. In this article, we show that bene, a gene previously identified on the basis of its oogenesis defects, is also required for larval growth and viability. We show that all bene alleles disrupt gatA, which encodes the Drosophila homolog of glutamyl-tRNA(Gln) amidotransferase subunit A (GatA). bene alleles are now referred to as gatA. GatA proteins are highly conserved throughout eukaryotes and many prokaryotes. These enzymes are required for proper translation of the proteins encoded by the mitochondrial genome and by many eubacterial genomes. Mitotic and endoreplicating tissues in Drosophila gatA loss-of-function mutants grow slowly and never achieve wild-type size, and gatA larvae die before pupariation. gatA mutant eye clones exhibit growth and differentiation defects, indicating that gatA expression is required cell autonomously for normal growth. The gatA gene is widely expressed in mitotic and endoreplicating tissues.

Hospital staffing and health care-associated infections: a systematic review of the literature.

In the past 10 years, many researchers have examined relationships between hospital staffing and patients' risk of health care-associated infection (HAI). To gain understanding of this evidence base, a systematic review was conducted, and 42 articles were audited. The most common infection studied was bloodstream infection (n=18; 43%). The majority of researchers examined nurse staffing (n=38; 90%); of these, only 7 (18%) did not find a statistically significant association between nurse staffing variable(s) and HAI rates. Use of nonpermanent staff was associated with increased rates of HAI in 4 studies (P<.05). Three studies addressed infection control professional staffing with mixed results. Physician staffing was not found to be associated with patients' HAI risk (n=2). The methods employed and operational definitions used for both staffing and HAI varied; despite this variability, trends were apparent. Research characterizing effective staffing for infection control departments is needed.

Assessment of attitudes of intensive care unit staff toward clinical practice guidelines.

Although studies on the implementation and adherence to specific practice guidelines have been proliferating, research examining the attitude of healthcare workers toward practice guidelines in general has been lacking. This study is a secondary analysis of data collected from 39 volunteer hospitals participating in the National Nosocomial Infection Surveillance System on attitudes of intensive care unit staff regarding practice guidelines in general. Age, profession, type of intensive care unit, and race were identified as significant predictors of attitude scores in this study. Understanding the differences in perceived barriers is important for the adherence to practice guidelines.

Non-hospital based registered nurses and the risk of bloodborne pathogen exposure.

The aim of this study was to assess the risk of blood and body fluid exposure among non-hospital based registered nurses (RNs) employed in New York State. The study population was mainly unionized public sector workers, employed in state institutions. A self-administered questionnaire was completed by a random stratified sample of members of the New York State Nurses Association and registered nurse members of the New York State Public Employees Federation. Results were reviewed by participatory action research (PAR) teams to identify opportunities for improvement. Nine percent of respondents reported at least one needlestick injury in the 12-month period prior to the study. The percutaneous injury (PI) rate was 13.8 per 100 person years. Under-reporting was common; 49% of all PIs were never formally reported and 70% never received any post-exposure care. Primary reasons for not reporting included: time constraints, fear, and lack of information on reporting. Significant correlates of needlestick injuries included tenure, patient load, hours worked, lack of compliance with standard precautions, handling needles and other sharps, poor safety climate, and inadequate training and availability of safety devices (p<0.05). PAR teams identified several risk reduction strategies, with an emphasis on safety devices. Non-hospital based RNs are at risk for bloodborne exposure at rates comparable to hospital based RNs; underreporting is an important obstacle to infection prevention, and primary and secondary risk management strategies appeared to be poorly implemented. Intervention research is warranted to evaluate improved risk reduction practices tailored to this population of RNs.

Certification in infection control matters: Impact of infection control department characteristics and policies on rates of multidrug-resistant infections.

BACKGROUND: The study objective is to describe infection control policies aimed at multidrug-resistant organisms (MDRO) in California hospitals and assess the relationship among these policies, structural characteristics, and rates of methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) bloodstream infections and Clostridium difficile infections. METHODS: Data on infection control policies, structural characteristics, and MDRO rates were collected through a 2010 survey of California infection control departments. Bivariate and multivariable Poisson and negative binomial regressions were conducted. RESULTS: One hundred eighty hospitals provided data (response rate, 54%). Targeted MRSA screening upon admission was reported by the majority of hospitals (87%). The majority of hospitals implemented contact precautions for confirmed MDRO and C difficile patients; presumptive isolation/contact precautions for patients with pending screens were less frequently implemented. Few infection control policies were associated with lower MDRO rates. Hospitals with a certified infection control director had significantly lower rates of MRSA bloodstream infections (P < .05). CONCLUSION: Although most California hospitals are involved in activities to decrease MDRO, there is variation in specific activities utilized with the most focus placed on MRSA. This study highlights the importance of certification and its significant impact on infection rates. Additional research is needed to confirm these findings.

Wide variation in adoption of screening and infection control interventions for multidrug-resistant organisms: a national study.

BACKGROUND: We performed a survey of National Healthcare Safety Network hospitals in 2008 to describe adoption of screening and infection control policies aimed at multidrug-resistant organisms (MDRO) in intensive care units (ICUs) and identify predictors of their presence, monitoring, and implementation. METHODS: Four hundred forty-one infection control directors were surveyed using a modified Dillman technique. To explore differences in screening and infection control policies by setting characteristics, bivariate and multivariable logistic regression models were constructed. RESULTS: In total, 250 hospitals participated (57% response rate). Study ICUs (n = 413) routinely screened for methicillin-resistant Staphylococcus aureus (59%); vancomycin-resistant Enterococcus (22%); multidrug-resistant, gram-negative rods (12%); and Clostridium difficile (11%). Directors reported ICU policies to screen all admissions for any MDRO (40%), screen periodically (27%), utilize presumptive isolation/contact precautions pending a screen (31%), and cohort colonized patients (42%). Several independent predictors of the presence and implementation of different interventions including mandatory reporting and teaching status were identified. CONCLUSION: This study found wide variation in adoption of MDRO screening and infection control interventions, which may reflect differences in published recommendations or their interpretation. Further research is needed to provide additional insight on effective strategies and how best to promote compliance.

Adoption of policies to prevent catheter-associated urinary tract infections in United States intensive care units.

BACKGROUND: Little is known about whether recommended strategies to prevent catheter-associated urinary tract infection (CAUTI) are being implemented in intensive care units (ICU) in the United States. OBJECTIVES: Our objectives were to describe the presence of and adherence to CAUTI prevention policies in ICUs, to identify variations in policies based on organizational characteristics, and to determine whether a relationship exists between prevention policies and CAUTI incidence rates. METHODS: Four hundred forty-one hospitals that participate in the National Healthcare Safety Network were surveyed in spring 2008. RESULTS: Two hundred fifty hospitals provided information for 415 ICUs (response rate, 57%). A small proportion of ICUs surveyed had policies supporting bladder ultrasound (26%, n = 106), condom catheters (20%, n = 82), catheter removal reminders (12%, n = 51), or nurse-initiated catheter discontinuation (10%, n = 39). ICUs in hospitals with ≥ 500 beds were half as likely as those in smaller hospitals to have adopted at least 1 CAUTI prevention policy (odds ratio, 0.52; 95% confidence interval: 0.33-0.86), and ICUs in hospitals where the infection control director reported always having access to key decision makers for planning were more than twice as likely as those with less access to have adopted a policy (odds ratio, 2.41; 95% confidence interval: 1.56-3.72). CONCLUSION: Little attention is currently placed on CAUTI prevention in ICUs in the United States. Further research is needed to elucidate relationships between adherence to CAUTI prevention recommendations and CAUTI incidence rates.

The APIC research agenda: results from a national survey.

BACKGROUND: Research is an integral component of the Association for Professionals in Infection Control and Epidemiology (APIC) Strategic Plan 2020. As the role of the infection preventionist (IP) has evolved toward consumers and implementers of research, it becomes increasingly necessary to assess which topics require further evidence and how best APIC can assist IPs. In 2010, APIC determined that the research priorities first described in 2000 needed to be re-evaluated. METHODS: A 33-question Web-based survey was developed and distributed via e-mail to APIC members in March 2011. The survey contained sections inquiring about respondents' demographics, familiarity with implementation science, and infection prevention research priorities. Priorities identified by a Delphi study 10 years ago were re-ranked, and open-ended items were used to identify new research priorities and understand how APIC could best serve its members in relation to research. RESULTS: Seven hundred one members responded. Behavioral management science, surveillance standards, and infection prevention resource optimization were the highest ranked priorities and relatively unchanged from 2000. Proposed additional research topics focused on achieving standardization in infection prevention practices and program resource allocation. The majority of respondents described APIC's role in the field of research as a disseminator of low-cost, highly accessible education to its members. CONCLUSION: This report should be used as a roadmap for APIC leadership as it provides suggestions on how APIC may best direct the association's research program. The major research priorities described and ranked in 2000 continue to challenge IPs. APIC can best serve its members by disseminating research findings in a cost-effective and easily accessed manner. Recurrent assessments of research priorities can help guide researchers and policy makers and help determine which topics will best support successful infection prevention processes and outcomes.

Central line bundle implementation in US intensive care units and impact on bloodstream infections.

BACKGROUND: Central line-associated bloodstream infections (CLABSI) represent a serious patient safety issue. To prevent these infections, bundled interventions are increasingly recommended. We examine the extent of adoption of Central Line (CL) Bundle elements throughout US intensive care units (ICU) and determine their effectiveness in preventing CLABSIs. METHODOLOGY/PRINCIPAL FINDINGS: In this cross-sectional study, National Healthcare Safety Network (NHSN) hospitals provided the following: ICU-specific NHSN-reported rates of CLABSI/1,000 central line days; policies and compliance rates regarding bundle components; and other setting characteristics. In 250 hospitals the mean CLABSI rate was 2.1 per 1000 central line days and 49% reported having a written CL Bundle policy. However, of those that monitored compliance, only 38% reported very high compliance with the CL Bundle. Only when an ICU had a policy, monitored compliance, and had ≥ 95% compliance did CLABSI rates decrease. Complying with any one of three CL Bundle elements resulted in decreased CLABSI rates (ß = -1.029, p = 0.015). If an ICU without good bundle compliance achieved high compliance with any one bundle element, we estimated that its CLABSI rate would decrease by 38%. CONCLUSIONS/SIGNIFICANCE: In NHSN hospitals across the US, the CL Bundle is associated with lower infection rates only when compliance is high. Hospitals must target improving bundle implementation and compliance as opposed to simply instituting policies.

Patient safety climate: variation in perceptions by infection preventionists and quality directors.

Background. Healthcare-associated infections (HAIs) are an important patient safety issue, and safety climate is an important organizational factor. This study explores perceptions of infection preventionists (IPs) and quality directors (QDs) regarding two safety microclimates, Senior Management Engagement (SME) and Leadership on Patient Safety (LOPS), across California hospitals. Methods. This was an analysis of two cross-sectional surveys. We conducted Wilcoxon signed-rank test, univariate analyses, and a multivariate ordinary least square regression. Results. There were 322 eligible hospitals; 149 hospitals (46.3%) responded to both surveys. The IP response rate was 59%, and the QD response rate was 79.5%. We found IPs perceived SME more positively than did QDs (21.4 vs. 20.4, P < 0.01). No setting characteristics predicted variation in perceptions. Presence of an independent budget predicted more positive perceptions of microclimates across personnel types (P < 0.01). Conclusions. Differences in perceptions continue to exist between essential leaders in acute health care settings which could have critical effects on outcomes such as HAIs. Having an independent budget for the infection prevention and control department may enhance the overall safety climate and in turn patient care.

Electronic surveillance systems in infection prevention: organizational support, program characteristics, and user satisfaction.

BACKGROUND: The use of electronic surveillance systems (ESSs) is gradually increasing in infection prevention and control programs. Little is known about the characteristics of hospitals that have a ESS, user satisfaction with ESSs, and organizational support for implementation of ESSs. METHODS: A total of 350 acute care hospitals in California were invited to participate in a Web-based survey; 207 hospitals (59%) agreed to participate. The survey included a description of infection prevention and control department staff, where and how they spent their time, a measure of organizational support for infection prevention and control, and reported experience with ESSs. RESULTS: Only 23% (44/192) of responding infection prevention and control departments had an ESS. No statistically significant difference was seen in how and where infection preventionists (IPs) who used an ESS and those who did not spend their time. The 2 significant predictors of whether an ESS was present were score on the Organizational Support Scale (odds ratio [OR], 1.10; 95% confidence interval [CI], 1.02-1.18) and hospital bed size (OR, 1.004; 95% CI, 1.00-1.007). Organizational support also was positively correlated with IP satisfaction with the ESS, as measured on the Computer Usability Scale (P = .02). CONCLUSION: Despite evidence that such systems may improve efficiency of data collection and potentially improve patient outcomes, ESSs remain relatively uncommon in infection prevention and control programs. Based on our findings, organizational support appears to be a major predictor of the presence, use, and satisfaction with ESSs in infection prevention and control programs.

Staffing and structure of infection prevention and control programs.

BACKGROUND: The nature of infection prevention and control is changing; however, little is known about current staffing and structure of infection prevention and control programs. METHODS: Our objectives were to provide a snapshot of the staffing and structure of hospital-based infection prevention and control programs in the United States. A Web-based survey was sent to 441 hospitals that participate in the National Healthcare Safety Network. RESULTS: The response rate was 66% (n = 289); data were examined on 821 professionals. Infection preventionist (IP) staffing was significantly negatively related to bed size, with higher staffing in smaller hospitals (P < .001). Median staffing was 1 IP per 167 beds. Forty-seven percent of IPs were certified, and 24 percent had less than 2 years of experience. Most directors or hospital epidemiologists were reported to have authority to close beds for outbreaks always or most of the time (n = 225, 78%). Only 32% (n = 92) reported using an electronic surveillance system to track infections. CONCLUSION: This study is the first to provide a comprehensive description of current infection prevention and control staffing, organization, and support in a select group of hospitals across the nation. Further research is needed to identify effective staffing levels for various hospital types as well as examine how the IP role is changing over time.

Home health care registered nurses and the risk of percutaneous injuries: a pilot study.

BACKGROUND: Home health care is the fastest-growing sector in the health care industry, expected to grow 66% over the next 10 years. Yet data on occupational health hazards, including the potential risk of exposure to blood and body fluids, associated with the home care setting remain very limited. As part of a larger study of bloodborne pathogen risk in non-hospital-based registered nurses (RNs), data from 72 home health care nurses were separately analyzed to identify risk of blood/body fluid exposure. METHODS: A 152-item self-administered mailed risk assessment questionnaire was completed by RNs employed in home health care agencies in New York State. RESULTS: Nine (13%) of the home health care nurses experienced 10 needlesticks in the 12-month period before the study. Only 4 of the needlesticks were formally reported to the nurse's employer. The devices most frequently associated with needlesticks were hollow-bore and phlebotomy needles, and included 3 needles with safety features. Exposure was most commonly attributed to patient actions, followed by disposal-related activities. CONCLUSIONS: These data suggest that home health care nurses may be at potential occupational risk for bloodborne pathogen exposure. Risk management strategies tailored to the home health care setting may be most effective in reducing this risk.
