This document introduces and explains common implementation concepts and frameworks relevant to healthcare epidemiology and infection prevention and control and can serve as a stand-alone guide or be paired with the "SHEA/IDSA/APIC Compendium of Strategies to Prevent Healthcare-Associated Infections in Acute Care Hospitals: 2022 Updates," which contain technical implementation guidance for specific healthcare-associated infections. This Compendium article focuses on broad behavioral and socio-adaptive concepts and suggests ways that infection prevention and control teams, healthcare epidemiologists, infection preventionists, and specialty groups may utilize them to deliver high-quality care. Implementation concepts, frameworks, and models can help bridge the "knowing-doing" gap, a term used to describe why practices in healthcare may diverge from those recommended according to evidence. It aims to guide the reader to think about implementation and to find resources suited for a specific setting and circumstances by describing strategies for implementation, including determinants and measurement, as well as the conceptual models and frameworks: 4Es, Behavior Change Wheel, CUSP, European and Mixed Methods, Getting to Outcomes, Model for Improvement, RE-AIM, REP, and Theoretical Domains.

Introduction: Podcasts have become popular among medical trainees. However, it is unclear how well learners retain information from podcasts compared to traditional educational modalities, and whether multitasking affects the learner's ability to pay attention and learn. This study attempted to examine the effectiveness of podcast learning by using electroencephalography (EEG) to measure learner attention, in addition to test performance, task load, and preferences., Methods: The study used a repeated measures design with three conditions: podcast listening on a treadmill, podcast listening seated, and textbook reading seated. Participants were anesthesiology residents and medical students at a large United States academic medical center. Three topics were chosen: allergic response, liver physiology, and statistics. Each participant studied all three topics that were randomly assigned to one of three learning conditions - in random order. Participants completed a knowledge test at baseline, after each condition, and at four-week follow-up, and reported preferred learning modality and task load under each modality. Activation levels in alerting, orienting, and executive attentional networks were examined using EEG.  Results: Sixty-one participants (11 anesthesiology residents and 50 medical students) were included in the study. Of the 61, six were excluded from the EEG analyses due to corrupted recordings. EEG results showed that mean attention network activation scores did not differ between the study conditions. Trainees preferred podcast learning over reading for all three topics. When compared to textbook reading, podcast learning (seated or on a treadmill) produced significantly better learning gain, and equivalent retention for two of the three topics., Conclusions: Our study is the first to use neurocognitive data, self-reported satisfaction, and knowledge test performance to demonstrate that podcasts are at least equivalent to textbooks for maintaining attention, immediate learning, and retention - even while exercising., Competing Interests: Jed Wolpaw is the founder and host of the Anesthesia and Critical Care Reviews and Commentary (ACCRAC) podcast but receives no financial compensation for the work which is provided free of charge to listeners.

Background: Formative events during training help shape professional identity and may impact well-being. This study sought to identify formative experiences during anesthesia residency and measure their perceived impact on well-being., Methods: A 24-item survey exploring the frequency and perceived impact of formative events was developed through a rigorous process involving a literature search, consultation with medical education experts, resident focus groups, graduate interviews, and pilot testing. All 80 anesthesiology residents at Johns Hopkins University were invited to participate. We measured the frequency of event exposure and perceived impact on well-being., Results: Seventy-six residents (95%) completed the survey. Event exposure rate ranged from 56.6% to 100%. Events with greatest relative impact (RI) overall included leaving work earlier than expected (RIoverall = 85.8), a patient expresses genuine gratitude (RIoverall = 80.2), identifying a faculty role model (RIoverall = 75.7), and having a patient die under my care (RIoverall = 75.6). There was no statistically significant difference on RI for positive versus negative events. The perceived impact of events on well-being varied by gender., Conclusions: This work provides clarity for residency program leaders and educators about the commonly experienced formative events that have the greatest perceived impact on resident well-being. These results may inform curricular planning and can suggest times when trainees may need attention or support. Future research should evaluate the direct impact of formative events on well-being and the success of related interventions., Competing Interests: Conflicts of interest: None, (© 2019 Society for Education in Anesthesia.)

Background: A Surgical Unit-based Safety Programme (SUSP) has been shown to improve perioperative prevention practices and to reduce surgical site infections (SSI). It is critical to understand the factors influencing the successful implementation of the SUSP approach in low- and middle-income settings. We undertook a qualitative study to assess viability, and understand facilitators and barriers to implementing the SUSP approach in 5 African hospitals., Methods: Qualitative study based on interviews with individuals from all hospitals participating in a WHO-coordinated before-after SUSP study. The SUSP intervention consisted of a multimodal strategy including multiple SSI prevention measures combined with an adaptive approach aimed at improving teamwork and safety culture., Results: Thirteen interviews (5 head surgeons, 3 surgeons, 5 nurses) were conducted with staff from five hospital sites. Identified facilitators included influential individuals (intrinsic motivation of local SUSP teams, boundary spanners, multidisciplinary engagement, active leadership support), peer-to-peer learning (hospital networking and positive deviance, benchmarking), implementation fitness (enabling infrastructures, momentum from previous projects), and timely feedback of infection rates and process indicators. Barriers (organisational 'constipators', workload, mistrust, turnover) and local solutions to these were also identified., Conclusions: Participating hospitals benefitted from the SUSP programme structures (e.g. surveillance, hospital networks, formation of multidisciplinary teams) and adaptive tools (e.g. learning from defects, executive rounds guide) to change perceptions around patient safety and improve behaviours to prevent SSI. The combination of technical and adaptive elements represents a promising approach to facilitate the introduction of evidence-based best practices and to improve safety culture through local team engagement in resource-limited settings., Competing Interests: Competing interestsThe authors report no competing interests.

Background: Evidence-based guidelines from the World Health Organization (WHO) have recommended a high (80%) fraction of inspired oxygen (FiO 2 ) to reduce surgical site infection in adult surgical patients undergoing general anaesthesia with tracheal intubation. However, there is ongoing debate over the safety of high FiO 2 . We performed a systematic review to define the relative risk of clinically relevant adverse events (AE) associated with high FiO 2 ., Methods: We reviewed potentially relevant articles from the WHO review supporting the recommendation, including an updated (July 2018) search of EMBASE and PubMed for randomised and non-randomised controlled studies reporting AE in surgical patients receiving 80% FiO 2 compared with 30-35% FiO 2 . We assessed study quality and performed meta-analyses of risk ratios (RR) comparing 80% FiO 2 against 30-35% for major complications, mortality, and intensive care admission., Results: We included 17 moderate-good quality trials and two non-randomised studies with serious-critical risk of bias. No evidence of harm with high FiO 2 was found for major AE in the meta-analysis of randomised trials: atelectasis RR 0.91 [95% confidence interval (CI) 0.59-1.42); cardiovascular events RR 0.90 (95% CI 0.32-2.54); intensive care admission RR 0.93 (95% CI 0.7-1.12); and death during the trial RR 0.49 (95% CI 0.17-1.37). One non-randomised study reported that high FiO 2 was associated with major respiratory AE [RR 1.99 (95% CI 1.72-2.31)]., Conclusions: No definite signal of harm with 80% FiO 2 in adult surgical patients undergoing general anaesthesia was demonstrated and there is little evidence on safety-related issues to discourage its use in this population., (Copyright © 2018 World Health Organization.

Background: Surgical site infections (SSIs) portend high patient morbidity and mortality. Although evidence-based clinical interventions can reduce SSIs, they are not reliably delivered in practice, and data are limited on the best approach to improve adherence., Objective: To summarize implementation strategies aimed at improving adherence to evidence-based interventions that reduce SSIs., Design: Systematic reviewMethods:We searched PubMed, Embase, CINAHL, the Cochrane Library, the WHO Regional databases, AFROLIB, and Africa-Wide for studies published between January 1990 and December 2015. The Effective Practice and Organization Care (EPOC) criteria were used to identify an acceptable-quality study design. We used structured forms to extract data on implementation strategies and grouped them into an implementation model called the "Four Es" framework (ie, engage, educate, execute, and evaluate)., Results: In total, 125 studies met our inclusion criteria, but only 8 studies met the EPOC criteria, which limited our ability to identify best practices. Most studies used multifaceted strategies to improve adherence with evidence-based interventions. Engagement strategies included multidisciplinary work and strong leadership involvement. Education strategies included various approaches to introduce evidence-based practices to clinicians and patients. Execution strategies standardized the interventions into simple tasks to facilitate uptake. Evaluation strategies assessed adherence with evidence-based interventions and patient outcomes, providing feedback of performance to providers., Conclusions: Multifaceted implementation strategies represent the most common approach to facilitating the adoption of evidence-based practices. We believe that this summary of implementation strategies complements existing clinical guidelines and may accelerate efforts to reduce SSIs.

BACKGROUND Measuring processes of care performance rates is an invaluable tool for quality improvement; however, collecting daily process measure data is time-consuming and burdensome. OBJECTIVE To evaluate the accuracy of sampling strategies to estimate monthly compliance rates with ventilator-associated pneumonia prevention measures. SETTING AND PARTICIPANTS A total of 37 intensive care units affiliated with 29 hospitals participating in a 2-state 35-month ventilator-associated pneumonia prevention collaborative. Analysis was limited to 325 unit-months with complete data entry rates. METHODS We calculated unit-month level actual and sample monthly compliance rates for 6 ventilator-associated pneumonia prevention measures, using 4 sampling strategies: sample 1 day per month, sample 1 day per week, sample 7 consecutive days per month, and sample 7 consecutive days per month plus additional consecutive days as necessary to obtain at least 30 ventilator-days for that month whenever possible. We compared sample versus actual rates using paired t test and χ2 test. RESULTS Mean sampling accuracy ranged 84%-97% for 1 day per month, 91%-98% for 1 day per week, 92%-98% for 7 consecutive days per month, and 96%-99% for 7 consecutive days with at least 30 days per month if possible. The most accurate sampling strategy was to sample 7 consecutive days with at least 30 ventilator-days per month if possible. With this strategy, sample rates were within 10% of actual rates in 88%-99% of unit-months and within 5% of actual rates in 74%-97% of unit-months. CONCLUSION Sampling process measures intermittently rather than continually can yield accurate estimates of process measure performance rates. Infect Control Hosp Epidemiol 2016;37:1037-1043.

Background: Ventilator-associated pneumonia (VAP) is among the most common type of health care-associated infection in the intensive care unit and is associated with significant morbidity and mortality. Existing VAP prevention intervention bundles vary widely on the interventions included and in the approaches used to develop these bundles. The objective of this study was to develop a new VAP prevention bundle using a systematic approach that elicits clinician perceptions on which interventions are most important and feasible to implement., Methods: We identified potential interventions to include through a review of current guidelines and literature. We implemented a 2-step modified Delphi method to gain consensus on the final list of interventions. An interdisciplinary group of clinical experts participated in the Delphi process, which was guided by a technical expert panel., Results: We identified 65 possible interventions. Through the Delphi method, we narrowed that list to 19 interventions that included 5 process and 14 structural measures., Conclusions: We described a structured approach for developing a new VAP prevention bundle. Obtaining clinician input on what interventions to include increases the likelihood that providers will adhere to the bundle., (Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc.

Immunization for influenza and pneumococcal pneumonia were incorporated into The Joint Commission "global immunization" core measure January 1, 2012. The authors' hospital chose to adhere strictly to guidelines to avoid overvaccination. An immunization order set was created to aid appropriate ordering practices. In spite of this effort, compliance rates remained below the goal. The objective was to improve compliance with inpatient vaccination core measures to >96%. An educational slide set was created and distributed by the Housestaff Patient Safety and Quality Council (HPSQC). A competition was established among departments. Finally, the HPSQC partnered with quality improvement staff to improve communication and optimize concurrent review processes. The average compliance prior to the HPSQC vaccination initiative was 78% for pneumococcal pneumonia and 84% for influenza; average compliance in the months following the intervention was 96% and 97.5%, respectively. This project yielded significant improvement in compliance with vaccination core measures., (© The Author(s) 2014.)
