The preventability of ventilator-associated events. The CDC Prevention Epicenters Wake Up and Breathe Collaborative.

RATIONALE: The CDC introduced ventilator-associated event (VAE) definitions in January 2013. Little is known about VAE prevention. We hypothesized that daily, coordinated spontaneous awakening trials (SATs) and spontaneous breathing trials (SBTs) might prevent VAEs. OBJECTIVES: To assess the preventability of VAEs. METHODS: We nested a multicenter quality improvement collaborative within a prospective study of VAE surveillance among 20 intensive care units between November 2011 and May 2013. Twelve units joined the collaborative and implemented an opt-out protocol for nurses and respiratory therapists to perform paired daily SATs and SBTs. The remaining eight units conducted surveillance alone. We measured temporal trends in VAEs using generalized mixed effects regression models adjusted for patient-level unit, age, sex, reason for intubation, Sequential Organ Failure Assessment score, and comorbidity index. MEASUREMENTS AND MAIN RESULTS: We tracked 5,164 consecutive episodes of mechanical ventilation: 3,425 in collaborative units and 1,739 in surveillance-only units. Within collaborative units, significant increases in SATs, SBTs, and percentage of SBTs performed without sedation were mirrored by significant decreases in duration of mechanical ventilation and hospital length-of-stay. There was no change in VAE risk per ventilator day but significant decreases in VAE risk per episode of mechanical ventilation (odds ratio [OR], 0.63; 95% confidence interval [CI], 0.42-0.97) and infection-related ventilator-associated complications (OR, 0.35; 95% CI, 0.17-0.71) but not pneumonias (OR, 0.51; 95% CI, 0.19-1.3). Within surveillance-only units, there were no significant changes in SAT, SBT, or VAE rates. CONCLUSIONS: Enhanced performance of paired, daily SATs and SBTs is associated with lower VAE rates. Clinical trial registered with www.clinicaltrials.gov (NCT 01583413).

Intervention to reduce transmission of resistant bacteria in intensive care.

BACKGROUND: Intensive care units (ICUs) are high-risk settings for the transmission of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococcus (VRE). METHODS: In a cluster-randomized trial, we evaluated the effect of surveillance for MRSA and VRE colonization and of the expanded use of barrier precautions (intervention) as compared with existing practice (control) on the incidence of MRSA or VRE colonization or infection in adult ICUs. Surveillance cultures were obtained from patients in all participating ICUs; the results were reported only to ICUs assigned to the intervention. In intervention ICUs, patients who were colonized or infected with MRSA or VRE were assigned to care with contact precautions; all the other patients were assigned to care with universal gloving until their discharge or until surveillance cultures obtained at admission were reported to be negative. RESULTS: During a 6-month intervention period, there were 5434 admissions to 10 intervention ICUs, and 3705 admissions to 8 control ICUs. Patients who were colonized or infected with MRSA or VRE were assigned to barrier precautions more frequently in intervention ICUs than in control ICUs (a median of 92% of ICU days with either contact precautions or universal gloving [51% with contact precautions and 43% with universal gloving] in intervention ICUs vs. a median of 38% of ICU days with contact precautions in control ICUs, P<0.001). In intervention ICUs, health care providers used clean gloves, gowns, and hand hygiene less frequently than required for contacts with patients assigned to barrier precautions; when contact precautions were specified, gloves were used for a median of 82% of contacts, gowns for 77% of contacts, and hand hygiene after 69% of contacts, and when universal gloving was specified, gloves were used for a median of 72% of contacts and hand hygiene after 62% of contacts. The mean (±SE) ICU-level incidence of events of colonization or infection with MRSA or VRE per 1000 patient-days at risk, adjusted for baseline incidence, did not differ significantly between the intervention and control ICUs (40.4±3.3 and 35.6±3.7 in the two groups, respectively; P=0.35). CONCLUSIONS: The intervention was not effective in reducing the transmission of MRSA or VRE, although the use of barrier precautions by providers was less than what was required.

The role of the public health analyst in the delivery of technical assistance to state health departments for healthcare-associated infection prevention.

INTRODUCTION: Aligned with the goals of the DHHS Action Plan to Prevent Healthcare Associated Infections (HAIs), in 2009 the Centers for Disease Control and Prevention (CDC) awarded cooperative agreements to 51 state and territorial health departments for purposes of developing and implementing strategies to reduce HAIs. These cooperative agreements through the Epidemiology and Laboratory Capacity for Infectious Diseases (ELC) were supported by the American Recovery and Reinvestment Act (ARRA). OBJECTIVES: To systematically describe the perceptions of CDC public health analysts who delivered technical assistance (TA) to state health departments as part of the ELC cooperative agreement supported by ARRA to develop, implement, and/or expand HAI prevention programs. RESEARCH DESIGN: Eight semistructured interviews using a standardized script were administered. Interviews were audio recorded; responses were transcribed, thematically coded, and analyzed using a qualitative immersion approach. SUBJECTS: This study included CDC staff who provided TA to grantees of the ELC cooperative agreement supported by ARRA from September 2009 to December 2011. RESULTS: Four convergent themes were identified, creating a framework of activities for the delivery of TA: acting as a liaison, facilitating training, providing administrative and program management support, and sharing/disseminating information to states. Having a liaison and providing informational resources to states were perceived as critical components of TA for HAI program sustainability. CONCLUSIONS: Findings provide a framework of core TA activities required to build and sustain capacity in state HAI prevention programs through the cooperative agreement structure. This categorization of themes can be used to assist other agencies and entities in planning for and provision of TA when utilizing cooperative agreements.

Enhancement of health department capacity for health care-associated infection prevention through Recovery Act-funded programs.

OBJECTIVES: We evaluated capacity built and outcomes achieved from September 1, 2009, to December 31, 2011, by 51 health departments (HDs) funded through the American Recovery and Reinvestment Act (ARRA) for health care-associated infection (HAI) program development. METHODS: We defined capacity for HAI prevention at HDs by 25 indicators of activity in 6 categories: staffing, partnerships, training, technical assistance, surveillance, and prevention. We assessed state-level infection outcomes by modeling quarterly standardized infection ratios (SIRs) for device- and procedure-associated infections with longitudinal regression models. RESULTS: With ARRA funds, HDs created 188 HAI-related positions and supported 1042 training programs, 53 surveillance data validation projects, and 60 prevention collaboratives. All states demonstrated significant declines in central line-associated bloodstream and surgical site infections. States that implemented ARRA-funded catheter-associated urinary tract infection prevention collaboratives showed significantly greater SIR reductions over time than states that did not (P = .02). CONCLUSIONS: ARRA-HAI funding substantially improved HD capacity to reduce HAIs not targeted by other national efforts, suggesting that HDs can play a critical role in addressing emerging or neglected HAIs.

Infection control and bloodstream infection prevention: the perspective of patients receiving hemodialysis.

Patients on hemodialysis, particularly those dialyzed through central lines, are at risk of acquiring bloodstream infections. Strategies to prevent bloodstream infections in patients on dialysis include educating patients about infection prevention, although patients' perspectives on this topic are not known. During focus groups conducted to explore these issues, patients reported that education on infection prevention should begin early in the process of dialysis, and that patients should be actively engaged as partners in infection prevention.

CDC's Hospital-Onset Clostridioides difficile Prevention Framework in a Regional Hospital Network.

Importance: Despite modest reductions in the incidence of hospital-onset Clostridioides difficile infection (HO-CDI), CDI remains a leading cause of health care-associated infection. As no single intervention has proven highly effective on its own, a multifaceted approach to controlling HO-CDI is needed. Objective: To assess the effectiveness of the Centers for Disease Control and Prevention's Strategies to Prevent Clostridioides difficile Infection in Acute Care Facilities Framework (hereafter, the Framework) in reducing HO-CDI incidence. Design, Setting, and Participants: This quality improvement study was performed within the Duke Infection Control Outreach Network from July 1, 2019, through March 31, 2022. In all, 20 hospitals in the network participated in an implementation study of the Framework recommendations, and 26 hospitals did not participate and served as controls. The Framework has 39 discrete intervention categories organized into 5 focal areas for CDI prevention: (1) isolation and contact precautions, (2) CDI confirmation, (3) environmental cleaning, (4) infrastructure development, and (5) antimicrobial stewardship engagement. Exposures: Monthly teleconferences supporting Framework implementation for the participating hospitals. Main Outcomes and Measures: Primary outcomes were HO-CDI incidence trends at participating hospitals compared with controls and postintervention HO-CDI incidence at intervention sites compared with rates during the 24 months before the intervention. Results: The study sample included a total of 2184 HO-CDI cases and 7 269 429 patient-days. In the intervention cohort of 20 participating hospitals, there were 1403 HO-CDI cases and 3 513 755 patient-days, with a median (IQR) HO-CDI incidence of 2.8 (2.0-4.3) cases per 10 000 patient-days. The first analysis included an additional 3 755 674 patient-days and 781 HO-CDI cases among the 26 controls, with a median (IQR) HO-CDI incidence of 1.1 (0.7-2.7) case per 10 000 patient-days. The second analysis included an additional 2 538 874 patient-days and 1751 HO-CDI cases, with a median (IQR) HO-CDI incidence of 5.9 (2.7-8.9) cases per 10 000 patient-days, from participating hospitals 24 months before the intervention. In the first analysis, intervention sites had a steeper decline in HO-CDI incidence over time relative to controls (yearly incidence rate ratio [IRR], 0.79 [95% CI, 0.67-0.94]; P = .01), but the decline was not temporally associated with study participation. In the second analysis, HO-CDI incidence was declining in participating hospitals before the intervention, and the rate of decline did not change during the intervention. The degree to which hospitals implemented the Framework was associated with steeper declines in HO-CDI incidence (yearly IRR, 0.95 [95% CI, 0.90-0.99]; P = .03). Conclusions and Relevance: In this quality improvement study of a regional hospital network, implementation of the Framework was not temporally associated with declining HO-CDI incidence. Further study of the effectiveness of multimodal prevention measures for controlling HO-CDI is warranted.

Survey Design: To Ask or Not to Ask? That is the Question...

Surveys are one of the most frequent modes of observation and measurement. Survey research can be exploratory, descriptive, and/or explanatory. Modes of survey administration vary and include face-to-face, telephone, mail, and Internet. There are numerous considerations that that must be taken into account when designing and conducting a survey. Deciding what information is needed and why is important when developing questions for a survey; it is essential to define the purpose of the survey and to be as specific as possible in terms of the data to be collected. Response rate varies by target audience and is influenced by a number of factors such as incentives, survey length, and perceived burden. From question development to survey construction, the goal is to minimize measurement error with systematic planning and execution.

Medical students' perceptions and knowledge about antimicrobial stewardship: how are we educating our future prescribers?

BACKGROUND: Better understanding of medical students' perceptions, attitudes, and knowledge about antimicrobial prescribing practices could facilitate more effective education of these future prescribers. METHODS: A 24-item electronic survey on antimicrobial prescribing and education was administered to fourth-year medical students at the University of Miami, the Johns Hopkins University, and the University of Washington (January-March 2012). RESULTS: Three hundred seventeen of 519 (61%) students completed the survey; 92% of respondents agreed that strong knowledge of antimicrobials is important in their careers, and 90% said that they would like more education on appropriate use of antimicrobials. Mean correct knowledge score (11 items) was 51%, with statistically significant differences between study sites and sources of information used to learn about antimicrobials. Only 15% had completed a clinical infectious diseases rotation during medical school; those who had done so rated the quality of their antimicrobial education significantly higher compared to those who had not (mean, 3.93 vs 3.44, on a 5-point scale; P = .0003). There were no statistically significant associations between knowledge scores and having had an infectious diseases clinical elective. Only one-third of respondents perceived their preparedness to be adequate in some fundamental principles of antimicrobial use. CONCLUSIONS: Differences exist between medical schools in educational resources used, perceived preparedness, and knowledge about antimicrobial use. Variability in formative education could frame behaviors and prescribing practices in future patient care. To help address the growing problem of antimicrobial resistance, efforts should be undertaken to ensure that our future doctors are well educated in the principles and practices of appropriate use of antibiotics and antimicrobial stewardship.

Assessment of public health perspectives on responding to an emerging pathogen: carbapenem-resistant Enterobacteriaceae.

CONTEXT: Public health has an important and critical role in responding to emerging multidrug-resistant organisms, such as carbapenem-resistant Enterobacteriaceae. The Centers for Disease Control and Prevention developed a survey as a tool for state health departments to determine carbapenem-resistant Enterobacteriaceae prevalence within their region. OBJECTIVE: This report summarizes an assessment of the health department experience with the survey, their perceived roles and responsibilities in responding to an emerging health care-associated pathogen, and potential barriers to public health engagement of acute care facilities in response activities. DESIGN: Key informant interviews consisting of open-ended and 5-point Likert scale questions were conducted. PARTICIPANTS: Interviewees represented state health departments that administered the survey and select states that did not. RESULTS: Of 11 states interviewed, 7 (64%) had administered the survey to acute care facilities. Despite similar competing priorities and concerns about administering the survey, different perspectives emerged among the 11 states; those that administered the survey regarded it as a learning opportunity, whereas other states emphasized concerns about survey logistics and other public health demands. All 11 states perceived the prevention of an emerging pathogen to be a public health priority, but the degree of their action depended on availability of resources and existing relationships with infection preventionists. Health departments had less interaction with other hospital personnel (eg, facility leadership) and limited knowledge of the roles and associated responsibilities of other health care partners (eg, Quality Improvement Organizations). CONCLUSIONS: Although considered a public health priority, response efforts to emerging pathogens were reported to vary among state health departments. A better understanding is needed of the factors that motivate and facilitate state health departments to engage in a public health activity despite the challenges of competing priorities and limited resources. Efforts should also focus on improving the relationship between health departments and hospital leadership and other health care partners.

A Review of Pediatric Central Line-Associated Bloodstream Infections Reported to the National Healthcare Safety Network: United States, 2016-2022.

Central line-associated bloodstream infections (CLABSIs) are common healthcare-associated infections in pediatrics. Children's hospital CLABSI standardized infection ratios decreased when comparing 2016-2019 (-26%, 95% CI [-31%, -20%]), and increased from 2019 to 2022 (18%, 95% CI [9%, 26%]). Resilient pediatric CLABSI prevention initiatives are needed.

A modified Delphi approach to develop a trial protocol for antibiotic de-escalation in patients with suspected sepsis.

Background: Early administration of antibiotics in sepsis is associated with improved patient outcomes, but safe and generalizable approaches to de-escalate or discontinue antibiotics after suspected sepsis events are unknown. Methods: We used a modified Delphi approach to identify safety criteria for an opt-out protocol to guide de-escalation or discontinuation of antibiotic therapy after 72 hours in non-ICU patients with suspected sepsis. An expert panel with expertise in antimicrobial stewardship and hospital epidemiology rated 48 unique criteria across 3 electronic survey rating tools. Criteria were rated primarily based on their impact on patient safety and feasibility for extraction from electronic health record review. The 48 unique criteria were rated by anonymous electronic survey tools, and the results were fed back to the expert panel participants. Consensus was achieved to either retain or remove each criterion. Results: After 3 rounds, 22 unique criteria remained as part of the opt-out safety checklist. These criteria included high-risk comorbidities, signs of severe illness, lack of cultures during sepsis work-up or antibiotic use prior to blood cultures, or ongoing signs and symptoms of infection. Conclusions: The modified Delphi approach is a useful method to achieve expert-level consensus in the absence of evidence suifficient to provide validated guidance. The Delphi approach allowed for flexibility in development of an opt-out trial protocol for sepsis antibiotic de-escalation. The utility of this protocol should be evaluated in a randomized controlled trial.

A qualitative assessment of factors affecting nursing home caregiving staff experiences during the COVID-19 pandemic.

BACKGROUND: A large portion of COVID-19 cases and deaths in the United States have occurred in nursing homes; however, current literature including the frontline perspective of staff working in nursing homes is limited. The objective of this qualitative assessment was to better understand what individual and facility level factors may have contributed to the impact of COVID-19 on Certified Nursing Assistants (CNAs) and Environmental Services (EVS) staff working in nursing homes. METHODS: Based on a simple random sample from the National Healthcare Safety Network (NHSN), 7,520 facilities were emailed invitations requesting one CNA and/or one EVS staff member for participation in a voluntary focus group over Zoom. Facility characteristics were obtained via NHSN and publicly available sources; participant demographics were collected via SurveyMonkey during registration and polling during focus groups. Qualitative information was coded using NVIVO and Excel. RESULTS: Throughout April 2021, 23 focus groups including 110 participants from 84 facilities were conducted homogenous by participant role. Staffing problems were a recurring theme reported. Participants often cited the toll the pandemic took on their emotional well-being, describing increased stress, responsibilities, and time needed to complete their jobs. The lack of consistent and systematic guidance resulting in frequently changing infection prevention protocols was also reported across focus groups. CONCLUSIONS: Addressing concerns of low wages and lack of financial incentives may have the potential to attract and retain employees to help alleviate nursing home staff shortages. Additionally, access to mental health resources could help nursing home staff cope with the emotional burden of the COVID-19 pandemic. These frontline staff members provided invaluable insight and should be included in improvement efforts to support nursing homes recovering from the impact of COVID-19 as well as future pandemic planning.

Infection control assessment of ambulatory surgical centers.

CONTEXT: More than 5000 ambulatory surgical centers (ASCs) in the United States participate in the Medicare program. Little is known about infection control practices in ASCs. The Centers for Medicare & Medicaid Services (CMS) piloted an infection control audit tool in a sample of ASC inspections to assess facility adherence to recommended practices. OBJECTIVE: To describe infection control practices in a sample of ASCs. DESIGN, SETTING, AND PARTICIPANTS: All State Survey Agencies were invited to participate. Seven states volunteered; 3 were selected based on geographic dispersion, number of ASCs each state committed to inspect, and relative cost per inspection. A stratified random sample of ASCs was selected from each state. Sample size was based on the number of inspections each state estimated it could complete between June and October 2008. Sixty-eight ASCs were assessed; 32 in Maryland, 16 in North Carolina, and 20 in Oklahoma. Surveyors from CMS, trained in use of the audit tool, assessed compliance with specific infection control practices. Assessments focused on 5 areas of infection control: hand hygiene, injection safety and medication handling, equipment reprocessing, environmental cleaning, and handling of blood glucose monitoring equipment. MAIN OUTCOME MEASURES: Proportion of facilities with lapses in each infection control category. RESULTS: Overall, 46 of 68 ASCs (67.6%; 95% confidence interval [CI], 55.9%-77.9%) had at least 1 lapse in infection control; 12 of 68 ASCs (17.6%; 95% CI, 9.9%-28.1%) had lapses identified in 3 or more of the 5 infection control categories. Common lapses included using single-dose medication vials for more than 1 patient (18/64; 28.1%; 95% CI, 18.2%-40.0%), failing to adhere to recommended practices regarding reprocessing of equipment (19/67; 28.4%; 95% CI, 18.6%-40.0%), and lapses in handling of blood glucose monitoring equipment (25/54; 46.3%; 95% CI, 33.4%-59.6%). CONCLUSION: Among a sample of US ASCs in 3 states, lapses in infection control were common.

Prevention of community-associated methicillin-resistant Staphylococcus aureus infection among Asian/Pacific Islanders: a qualitative assessment.

BACKGROUND: Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has been increasingly reported over the past decade, including in Asian/Pacific Islanders (A/PIs). METHODS: We conducted ethnographic interviews in O'ahu and Kaua'i, Hawai'i, with 10 Asian/Pacific Islanders identified as having a history of CA-MRSA infections. RESULTS: Most (7/10) thought skin infections were not a new problem in Hawai'i. Most (8/9) attempted to self-treat the infection prior to seeking medical care with a range of home remedies and store- bought solutions. Most respondents did not initially comprehend the severity of their infection and only sought medical treatment after concern from family, unbearable pain, and/or other symptoms of illness. CONCLUSION: Clinicians should be aware of the reportedly frequent use of home remedies by this population, as it may potentially contribute to interactions when treatments are combined. If clinicians and public health professionals do not address perceptions and misperceptions of how MRSA is acquired, it will be very difficult to prevent infection, and may also delay individuals from seeking treatment.

Pathogens causing central-line-associated bloodstream infections in acute-care hospitals-United States, 2011-2017.

OBJECTIVE: To describe pathogen distribution and rates for central-line-associated bloodstream infections (CLABSIs) from different acute-care locations during 2011-2017 to inform prevention efforts. METHODS: CLABSI data from the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) were analyzed. Percentages and pooled mean incidence density rates were calculated for a variety of pathogens and stratified by acute-care location groups (adult intensive care units [ICUs], pediatric ICUs [PICUs], adult wards, pediatric wards, and oncology wards). RESULTS: From 2011 to 2017, 136,264 CLABSIs were reported to the NHSN by adult and pediatric acute-care locations; adult ICUs and wards reported the most CLABSIs: 59,461 (44%) and 40,763 (30%), respectively. In 2017, the most common pathogens were Candida spp/yeast in adult ICUs (27%) and Enterobacteriaceae in adult wards, pediatric wards, oncology wards, and PICUs (23%-31%). Most pathogen-specific CLABSI rates decreased over time, excepting Candida spp/yeast in adult ICUs and Enterobacteriaceae in oncology wards, which increased, and Staphylococcus aureus rates in pediatric locations, which did not change. CONCLUSIONS: The pathogens associated with CLABSIs differ across acute-care location groups. Learning how pathogen-targeted prevention efforts could augment current prevention strategies, such as strategies aimed at preventing Candida spp/yeast and Enterobacteriaceae CLABSIs, might further reduce national rates.

A national survey of testing and management of asymptomatic carriage of C. difficile.

A nationwide survey indicated that screening for asymptomatic carriers of C. difficile is an uncommon practice in US healthcare settings. Better understanding of the role of asymptomatic carriage in C. difficile transmission, and of the measures available to reduce that risk, are needed to inform best practices regarding the management of carriers.

Evaluation of a program to improve hand hygiene in Kenyan hospitals through production and promotion of alcohol-based Handrub - 2012-2014.

Although critical to prevent healthcare-associated infections, hand hygiene (HH) compliance is poor in resource-limited settings. In 2012, three Kenyan hospitals began onsite production of alcohol-based handrub (ABHR) and HH promotion. Our aim is to determine the impact of local production of ABHR on HH compliance and perceptions of ABHR. We observed 25,738 HH compliance opportunities and conducted 15 baseline and post-intervention focus group discussions. Hand Hygiene compliance increased from 28% (baseline) to 38% (post-intervention, p = 0.0003). Healthcare workers liked the increased accessibility of ABHR, but disliked its smell, feel, and sporadic availability. Onsite production and promotion of ABHR resulted in modest HH improvement. Enhancing the quality of ABHR and addressing logistical barriers could improve program impact.

Hand hygiene practices after brief encounters with patients: an important opportunity for prevention.

OBJECTIVE: To identify characteristics of encounters between healthcare workers (HCWs) and patients that correlated with hand hygiene adherence among HCWs. DESIGN: Observational study. SETTING: Intensive care unit in a Veterans Affairs hospital. PARTICIPANTS: HCWs. RESULTS: There were 767 patient encounters observed (48.6% involved nurses, 20.6% involved physicians, and 30.8% involved other HCWs); 39.8% of encounters involved patients placed under contact precautions. HCW contact with either the patient or surfaces in the patient's environment occurred during all encounters; direct patient contact occurred during 439 encounters (57.4%), and contact with environmental surfaces occurred during 710 encounters (92.6%). The median duration of encounters was 2 minutes (range, <1 to 51 minutes); 33.6% of encounters lasted 1 minute or less, with no significant occupation-associated differences in the median duration of encounters. Adherence with hand hygiene practices was correlated with the duration of the encounter, with overall adherences of 30.0% after encounters of < or =1 minute, 43.4% after encounters of >1 to < or =2 minutes, 51.1% after encounters of >3 to < or =5 minutes, and 64.9% after encounters of >5 minutes (P<.001 by the chi (2) for trend). In multivariate analyses, longer encounter duration, contact precautions status, patient contact, and nursing occupation were independently associated with adherence to hand hygiene recommendations. CONCLUSIONS: In this study, adherence to hand hygiene practices was lowest after brief patient encounters (i.e., < 2 minutes). Brief encounters accounted for a substantial proportion of all observed encounters, and opportunities for hand contamination occurred during all brief encounters. Therefore, improving adherence after brief encounters may have an important overall impact on the transmission of healthcare-associated pathogens and may deserve special emphasis in the design of programs to promote adherence to hand hygiene practices.

Impact of different methods of feedback to clinicians after postprescription antimicrobial review based on the Centers For Disease Control and Prevention's 12 Steps to Prevent Antimicrobial Resistance Among Hospitalized Adults.

OBJECTIVES: To evaluate (1) the framework of the 12 Steps to Prevent Antimicrobial Resistance Among Hospitalized Adults that is part of the Centers for Disease Control and Prevention (CDC) Campaign to Prevent Antimicrobial Resistance in Healthcare Settings, with regard to steps addressing antimicrobial use; and (2) methods of feedback to clinicians regarding antimicrobial use after postprescription review. DESIGN: Prospective intervention to identify and modify inappropriate antimicrobial therapy. SETTING: A 1,000-bed, tertiary care teaching hospital. PATIENTS: Inpatients in selected medicine and surgery units receiving broad-spectrum antimicrobials for 48-72 hours. INTERVENTIONS: We created a computer-based clinical-event detection system that automatically identified inpatients taking broad-spectrum and "reserve" antimicrobials for 48-72 hours. Although prior approval was required for initial administration of broad-spectrum and reserve antimicrobials, once approval was obtained, therapy with the antimicrobials could be continued indefinitely at the discretion of the treating clinician. Therapy that was ongoing at 48-72 hours was reviewed by an infectious diseases pharmacist or physician, and when indicated feedback was provided to clinicians to modify or discontinue therapy. Feedback was provided via a direct telephone call, a note on the front of the medical record, or text message sent to the clinician's pager. The acceptance rate of feedback was recorded and recommendations were categorized according to the 12 steps recommended by the CDC. RESULTS: Interventions were recommended for 334 (30%) of 1,104 courses of antimicrobial therapy reviewed. A total of 87% of interventions fit into one of the CDC's 12 steps of prevention: 39% into step 3 ("target the pathogen"), 1% into step 4 ("access experts"), 3% into steps 7 and 8 ("treat infection, not colonization or contamination"), 18% into step 9 ("say ;no' to vancomycin"), and 26% into step 10 ("stop treatment when no infection"). The rate of compliance with recommendations to improve antimicrobial use was 72%. No differences in compliance were seen with the different methods of feedback. CONCLUSIONS: Nearly one-third of antimicrobial courses did not follow the CDC's recommended 12 steps for prevention of antimicrobial resistance. Clinicians demonstrated high compliance with following suggestions made after postprescription review, suggesting that it is a useful approach to decreasing and improving antimicrobial use among inpatients.

Infectious diseases physicians' preferences for continuing medical education on antimicrobial resistance and other general topics.

A 19-item survey instrument was designed and mailed by the Infectious Diseases Society of America to its membership to determine the media preferred by infectious diseases physicians for continuing medical education on general topics and on antimicrobial resistance. The objective of the survey was to offer the developers of educational programs knowledge on which to base more-effective ways to deliver educational materials to physicians in this specialty.
