Changes in medical errors after implementation of a handoff program.

BACKGROUND: Miscommunications are a leading cause of serious medical errors. Data from multicenter studies assessing programs designed to improve handoff of information about patient care are lacking. METHODS: We conducted a prospective intervention study of a resident handoff-improvement program in nine hospitals, measuring rates of medical errors, preventable adverse events, and miscommunications, as well as resident workflow. The intervention included a mnemonic to standardize oral and written handoffs, handoff and communication training, a faculty development and observation program, and a sustainability campaign. Error rates were measured through active surveillance. Handoffs were assessed by means of evaluation of printed handoff documents and audio recordings. Workflow was assessed through time-motion observations. The primary outcome had two components: medical errors and preventable adverse events. RESULTS: In 10,740 patient admissions, the medical-error rate decreased by 23% from the preintervention period to the postintervention period (24.5 vs. 18.8 per 100 admissions, P<0.001), and the rate of preventable adverse events decreased by 30% (4.7 vs. 3.3 events per 100 admissions, P<0.001). The rate of nonpreventable adverse events did not change significantly (3.0 and 2.8 events per 100 admissions, P=0.79). Site-level analyses showed significant error reductions at six of nine sites. Across sites, significant increases were observed in the inclusion of all prespecified key elements in written documents and oral communication during handoff (nine written and five oral elements; P<0.001 for all 14 comparisons). There were no significant changes from the preintervention period to the postintervention period in the duration of oral handoffs (2.4 and 2.5 minutes per patient, respectively; P=0.55) or in resident workflow, including patient-family contact and computer time. CONCLUSIONS: Implementation of the handoff program was associated with reductions in medical errors and in preventable adverse events and with improvements in communication, without a negative effect on workflow.

Integrating Research, Quality Improvement, and Medical Education for Better Handoffs and Safer Care: Disseminating, Adapting, and Implementing the I-PASS Program.

BACKGROUND: In 2009 the I-PASS Study Group was formed by patient safety, medical education, health services research, and clinical experts from multiple institutions in the United States and Canada. When the I-PASS Handoff Program, which was developed by the I-PASS Study Group, was implemented in nine hospitals, it was associated with a 30% reduction in injuries due to medical errors and significant improvements in handoff processes, without any adverse effects on provider work flow. METHODS: To effectively disseminate and adapt I-PASS for use across specialties and disciplines, a series of federally and privately funded dissemination and implementation projects were carried out following the publication of the initial study. The results of these efforts have informed ongoing initiatives intended to continue adapting and scaling the program. RESULTS: As of this writing, I-PASS Study Group members have directly worked with more than 50 hospitals to facilitate implementation of I-PASS. To further disseminate I-PASS, Study Group members delivered hundreds of academic presentations, including plenaries at scientific meetings, workshops, and institutional Grand Rounds. Some 3,563 individuals, representing more than 500 institutions in the 50 states in the United States, the District of Columbia, Puerto Rico, and 57 other countries, have requested access to I-PASS materials. Most recently, the I-PASSSM Patient Safety Institute has developed a virtual immersion training platform, mobile handoff observational tools, and processes to facilitate further spread of I-PASS. CONCLUSION: Implementation of I-PASS has been associated with substantial improvements in patient safety and can be applied to a variety of disciplines and types of patient handoffs. Widespread implementation of I-PASS has the potential to substantially improve patient safety in the United States and beyond.

Implementing a Family-Centered Rounds Intervention Using Novel Mentor-Trios.

BACKGROUND AND OBJECTIVES: Patient and Family Centered I-PASS (PFC I-PASS) emphasizes family and nurse engagement, health literacy, and structured communication on family-centered rounds organized around the I-PASS framework (Illness severity-Patient summary-Action items-Situational awareness-Synthesis by receiver). We assessed adherence, safety, and experience after implementing PFC I-PASS using a novel "Mentor-Trio" implementation approach with multidisciplinary parent-nurse-physician teams coaching sites. METHODS: Hybrid Type II effectiveness-implementation study from 2/29/19-3/13/22 with ≥3 months of baseline and 12 months of postimplementation data collection/site across 21 US community and tertiary pediatric teaching hospitals. We conducted rounds observations and surveyed nurses, physicians, and Arabic/Chinese/English/Spanish-speaking patients/parents. RESULTS: We conducted 4557 rounds observations and received 2285 patient/family, 1240 resident, 819 nurse, and 378 attending surveys. Adherence to all I-PASS components, bedside rounding, written rounds summaries, family and nurse engagement, and plain language improved post-implementation (13.0%-60.8% absolute increase by item), all P < .05. Except for written summary, improvements sustained 12 months post-implementation. Resident-reported harms/1000-resident-days were unchanged overall but decreased in larger hospitals (116.9 to 86.3 to 72.3 pre versus early- versus late-implementation, P = .006), hospitals with greater nurse engagement on rounds (110.6 to 73.3 to 65.3, P < .001), and greater adherence to I-PASS structure (95.3 to 73.6 to 72.3, P < .05). Twelve of 12 measures of staff safety climate improved (eg, "excellent"/"very good" safety grade improved from 80.4% to 86.3% to 88.0%), all P < .05. Patient/family experience and teaching were unchanged. CONCLUSIONS: Hospitals successfully used Mentor-Trios to implement PFC I-PASS. Family/nurse engagement, safety climate, and harms improved in larger hospitals and hospitals with better nurse engagement and intervention adherence. Patient/family experience and teaching were not affected.

Rates of medical errors and preventable adverse events among hospitalized children following implementation of a resident handoff bundle.

IMPORTANCE: Handoff miscommunications are a leading cause of medical errors. Studies comprehensively assessing handoff improvement programs are lacking. OBJECTIVE: To determine whether introduction of a multifaceted handoff program was associated with reduced rates of medical errors and preventable adverse events, fewer omissions of key data in written handoffs, improved verbal handoffs, and changes in resident-physician workflow. DESIGN, SETTING, AND PARTICIPANTS: Prospective intervention study of 1255 patient admissions (642 before and 613 after the intervention) involving 84 resident physicians (42 before and 42 after the intervention) from July-September 2009 and November 2009-January 2010 on 2 inpatient units at Boston Children's Hospital. INTERVENTIONS: Resident handoff bundle, consisting of standardized communication and handoff training, a verbal mnemonic, and a new team handoff structure. On one unit, a computerized handoff tool linked to the electronic medical record was introduced. MAIN OUTCOMES AND MEASURES: The primary outcomes were the rates of medical errors and preventable adverse events measured by daily systematic surveillance. The secondary outcomes were omissions in the printed handoff document and resident time-motion activity. RESULTS: Medical errors decreased from 33.8 per 100 admissions (95% CI, 27.3-40.3) to 18.3 per 100 admissions (95% CI, 14.7-21.9; P < .001), and preventable adverse events decreased from 3.3 per 100 admissions (95% CI, 1.7-4.8) to 1.5 (95% CI, 0.51-2.4) per 100 admissions (P = .04) following the intervention. There were fewer omissions of key handoff elements on printed handoff documents, especially on the unit that received the computerized handoff tool (significant reductions of omissions in 11 of 14 categories with computerized tool; significant reductions in 2 of 14 categories without computerized tool). Physicians spent a greater percentage of time in a 24-hour period at the patient bedside after the intervention (8.3%; 95% CI 7.1%-9.8%) vs 10.6% (95% CI, 9.2%-12.2%; P = .03). The average duration of verbal handoffs per patient did not change. Verbal handoffs were more likely to occur in a quiet location (33.3%; 95% CI, 14.5%-52.2% vs 67.9%; 95% CI, 50.6%-85.2%; P = .03) and private location (50.0%; 95% CI, 30%-70% vs 85.7%; 95% CI, 72.8%-98.7%; P = .007) after the intervention. CONCLUSIONS AND RELEVANCE: Implementation of a handoff bundle was associated with a significant reduction in medical errors and preventable adverse events among hospitalized children. Improvements in verbal and written handoff processes occurred, and resident workflow did not change adversely.

Implementation of the I-PASS handoff program in diverse clinical environments: A multicenter prospective effectiveness implementation study.

BACKGROUND: Handoff miscommunications are a leading source of medical errors. Harmful medical errors decreased in pediatric academic hospitals following implementation of the I-PASS handoff improvement program. However, implementation across specialties has not been assessed. OBJECTIVE: To determine if I-PASS implementation across diverse settings would be associated with improvements in patient safety and communication. DESIGN: Prospective Type 2 Hybrid effectiveness implementation study. SETTINGS AND PARTICIPANTS: Residents from diverse specialties across 32 hospitals (12 community, 20 academic). INTERVENTION: External teams provided longitudinal coaching over 18 months to facilitate implementation of an enhanced I-PASS program and monthly metric reviews. MAIN OUTCOME AND MEASURES: Systematic surveillance surveys assessed rates of resident-reported adverse events. Validated direct observation tools measured verbal and written handoff quality. RESULTS: 2735 resident physicians and 760 faculty champions from multiple specialties (16 internal medicine, 13 pediatric, 3 other) participated. 1942 error surveillance reports were collected. Major and minor handoff-related reported adverse events decreased 47% following implementation, from 1.7 to 0.9 major events/person-year (p < .05) and 17.5 to 9.3 minor events/person-year (p < .001). Implementation was associated with increased inclusion of all five key handoff data elements in verbal (20% vs. 66%, p < .001, n = 4812) and written (10% vs. 74%, p < .001, n = 1787) handoffs, as well as increased frequency of handoffs with high quality verbal (39% vs. 81% p < .001) and written (29% vs. 78%, p < .001) patient summaries, verbal (29% vs. 78%, p < .001) and written (24% vs. 73%, p < .001) contingency plans, and verbal receiver syntheses (31% vs. 83%, p < .001). Improvement was similar across provider types (adult vs. pediatric) and settings (community vs. academic).

Patient and Family-Centered I-PASS SCORE Program: Resident and Advanced Care Provider Training Materials.

Introduction: Patient and family-centered rounds (PFCRs) are an important element of family-centered care often used in the inpatient pediatric setting. However, techniques and best practices vary, and faculty, trainees, nurses, and advanced care providers may not receive formal education in strategies that specifically enhance communication on PFCRs. Methods: Harnessing the use of structured communication, we developed the Patient and Family-Centered I-PASS Safer Communication on Rounds Every Time (SCORE) Program. The program uses a standardized framework for rounds communication via the I-PASS mnemonic, principles of health literacy, and techniques for patient/family engagement and bidirectional communication. The resident and advanced care provider training materials, a component of the larger SCORE Program, incorporate a flipped classroom approach as well as interactive exercises, simulations, and virtual learning options to optimize learning and retention via a 90-minute workshop. Results: Two hundred forty-six residents completed the training and were evaluated on their knowledge and confidence regarding key elements of the curriculum. Eighty-eight percent of residents agreed/strongly agreed that after training they could activate and engage families and all members of the interprofessional team to create a shared mental model; 90% agreed/strongly agreed that they could discuss the roles/responsibilities of various team members during PFCRs. Discussion: The Patient and Family-Centered I-PASS SCORE Program provides a structured framework for teaching advanced communication techniques that can improve provider knowledge of and confidence with engaging and communicating with patients/families and other members of the interprofessional team during PFCRs.

Association of Patient and Family Reports of Hospital Safety Climate With Language Proficiency in the US.

Importance: Patients with language barriers have a higher risk of experiencing hospital safety events. This study hypothesized that language barriers would be associated with poorer perceptions of hospital safety climate relating to communication openness. Objective: To examine disparities in reported hospital safety climate by language proficiency in a cohort of hospitalized children and their families. Design, Setting, and Participants: This cohort study conducted from April 29, 2019, through March 1, 2020, included pediatric patients and parents or caregivers of hospitalized children at general and subspecialty units at 21 US hospitals. Randomly selected Arabic-, Chinese-, English-, and Spanish-speaking hospitalized patients and families were approached before hospital discharge and were included in the analysis if they provided both language proficiency and health literacy data. Participants self-rated language proficiency via surveys. Limited English proficiency was defined as an answer of anything other than "very well" to the question "how well do you speak English?" Main Outcomes and Measures: Primary outcomes were top-box (top most; eg, strongly agree) 5-point Likert scale ratings for 3 Children's Hospital Safety Climate Questionnaire communication openness items: (1) freely speaking up if you see something that may negatively affect care (top-box response: strongly agree), (2) questioning decisions or actions of health care providers (top-box response: strongly agree), and (3) being afraid to ask questions when something does not seem right (top-box response: strongly disagree [reverse-coded item]). Covariates included health literacy and sociodemographic characteristics. Logistic regression was used with generalized estimating equations to control for clustering by site to model associations between openness items and language proficiency, adjusting for health literacy and sociodemographic characteristics. Results: Of 813 patients, parents, and caregivers who were approached to participate in the study, 608 completed surveys (74.8% response rate). A total of 87.7% (533 of 608) of participants (434 [82.0%] female individuals) completed language proficiency and health literacy items and were included in the analyses; of these, 14.1% (75) had limited English proficiency. Participants with limited English proficiency had lower odds of freely speaking up if they see something that may negatively affect care (adjusted odds ratio [aOR], 0.26; 95% CI, 0.15-0.43), questioning decisions or actions of health care providers (aOR, 0.19; 95% CI, 0.09-0.41), and being unafraid to ask questions when something does not seem right (aOR, 0.44; 95% CI, 0.27-0.71). Individuals with limited health literacy (aOR, 0.66; 95% CI, 0.48-0.91) and a lower level of educational attainment (aOR, 0.59; 95% CI, 0.36-0.95) were also less likely to question decisions or actions. Conclusions and Relevance: This cohort study found that limited English proficiency was associated with lower odds of speaking up, questioning decisions or actions of providers, and being unafraid to ask questions when something does not seem right. This disparity may contribute to higher hospital safety risk for patients with limited English proficiency. Dedicated efforts to improve communication with patients and families with limited English proficiency are necessary to improve hospital safety and reduce disparities.

Leadership Training in Pediatric Residency Programs: Identifying Content, Characterizing Practice, and Planning for the Future.

OBJECTIVE: Physicians serve as leaders in varying roles, but often with minimal dedicated training. Existing pediatric residency competencies may not completely describe all leadership skills that should be valued. We sought to identify a set of high-value leadership skills and evaluate current training in these skills in pediatric residency programs. METHODS: A modified Delphi process was used to inform a national survey of pediatric residency program directors. Programs were asked to rate the perceived importance of identified leadership skills and the presence of dedicated teaching. Skills identified as extremely or quite important by ≥90% of respondents were classified as high-value. RESULTS: Our modified Delphi process generated 16 core leadership skills to evaluate. A total of 67/204 residency programs responded. Six skills were identified as high-value: managing time effectively, receiving feedback, communicating effectively through speaking, embodying professionalism, demonstrating emotional intelligence, and addressing conflict. Only 19% of responding programs reported providing dedicated teaching time for all high-value skills. CONCLUSIONS: Despite a high degree of national agreement among program directors about the importance of specific leadership skills, few pediatric residency programs dedicate time to teaching residents about these skills. The identified high-value leadership skills could help to inform future educational efforts.

I-PASS Mentored Implementation Handoff Curriculum: Frontline Provider Training Materials.

Introduction: The I-PASS Handoff Program is a comprehensive handoff curriculum that has been shown to decrease rates of medical errors and adverse events during patient handoffs. Frontline providers are the key individuals participating in handoffs of patient care. It is important they receive robust handoff training. Methods: The I-PASS Mentored Implementation Handoff Curriculum frontline provider training materials were created as part of the original I-PASS Study and adapted for the Society of Hospital Medicine (SHM) I-PASS Mentored Implementation Program. The adapted materials embrace a flipped classroom approach with an emphasis on adult learning theory principles. The training includes an overview of I-PASS handoff techniques, TeamSTEPPS team communication strategies, verbal handoff simulation scenarios, and a printed handoff document exercise. Results: As part of the SHM I-PASS Mentored Implementation Program, 2,735 frontline providers were trained at 32 study sites (16 adult and 16 pediatric) across North America. At the end of their training, 1,762 frontline providers completed the workshop evaluation form (64% response rate). After receiving the training, over 90% agreed/strongly agreed that they were able to distinguish a good- from a poor-quality handoff, articulate the elements of the I-PASS mnemonic, construct a high-quality patient summary, advocate for an appropriate environment for handoffs, and participate in handoff simulations. Universally, the training provided them with knowledge and skills relevant to their patient care activities. Discussion: The I-PASS frontline training materials were rated highly by those trained and are an integral part of a successful I-PASS Handoff Program implementation.

Changes in attendance at deliveries by pediatric residents 2000 to 2005.

We sought to determine if pediatric resident attendance at deliveries for newborn assessment and resuscitation had changed over the years at a training hospital. Data were abstracted from medical records of newborns discharged during the same 6-week periods for 5 consecutive academic years spanning a period before and after resident duty hour regulation changes were implemented. Names of personnel attending deliveries were noted in delivery records. The proportions of deliveries attended by any practitioner were compared by year, as well as the proportion of deliveries attended by practitioner type and training level. A total of 2666 delivery records were reviewed. The proportions of deliveries attended by any practitioner over the 5 years were similar, ranging from 43 to 49%. The proportion of deliveries attended by pediatric residents was highest at 51 to 57% from 2000 to 2002, declined to a low of 5% during 2002 to 2003, and rose to 20 to 23% during 2003 to 2005 ( P < 0.0001). The decrease in attendance by residents was compensated by an increase in attendance by hospitalists. At this training institution, pediatric resident attendance at deliveries declined substantially over recent years, likely due in part to resident duty hour regulations and increased use of hospitalists in roles previously held by residents.

Pediatric Hospital Medicine: Where We Are, Where We Are Headed: State of the Specialty, Looking Forward.

Although pediatric hospital medicine (PHM) is in its adolescence, it is already having a major impact on patient care, quality, safety, and education. Pediatric hospitalists have been front-and-center in the safety and quality movement, driving change as clinicians, applying evidence-based medicine to standardize practice and promulgate evidence-based guidelines, and playing a central role in optimizing the function of inter-professional teams. Pediatric hospitalists have championed the importance of patient-and family-centeredness of care and the need to incorporate principles of health literacy into all aspects of clinical care and research. Beyond delivering care, pediatric hospitalists have prominent roles as hospital leaders, educators, and researchers and have played a critical role in promoting improvements in health and health care outcomes. In its continued evolution, clinical care will undoubtedly remain the major focus, though with subspecialty status, the field will be expected to accelerate innovations in systems-based practice, advance clinical learning environments, and drive further improvements in quality of care.

Association of Pediatric Resident Physician Depression and Burnout With Harmful Medical Errors on Inpatient Services.

PURPOSE: To determine whether higher rates of medical errors were associated with positive screenings for depression or burnout among resident physicians. METHOD: The authors conducted a prospective cohort study from 2011 to 2013 in seven pediatric academic medical centers in the United States and Canada. Resident physicians were screened for burnout and depression using the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) and Harvard Department of Psychiatry/National Depression Screening Day Scale (HANDS). A two-step surveillance methodology, involving a research nurse and two physician reviewers, was used to measure and categorize errors. Bivariate and mixed-effects regression models were used to evaluate the relationship between burnout, depression, and rates of harmful, nonharmful, and total errors. RESULTS: A total of 388/537 (72%) resident physicians completed the MBI-HSS and HANDS surveys. Seventy-six (20%) and 178 (46%) resident physicians screened positive for depression and burnout, respectively. Screening positive for depression was associated with a 3.0-fold higher rate of harmful errors (incidence rate ratio = 2.99 [95% CI 1.40-6.36], P = .005). However, there was no statistically significant association between depression and total or nonharmful errors or between burnout and harmful, nonharmful, or total errors. CONCLUSIONS: Resident physicians with a positive depression screen were three times more likely than those who screened negative to make harmful errors. This association suggests resident physician mental health could be an important component of patient safety. If further research confirms resident physician depression increases the risk of harmful errors, it will become imperative to determine what interventions might mitigate this risk.

I-PASS Mentored Implementation Handoff Curriculum: Champion Training Materials.

Introduction: The I-PASS Handoff Program is a comprehensive handoff curriculum that has been shown to decrease rates of medical errors and adverse events during patient handoffs. I-PASS champions are a critical part of the implementation and sustainment of this curriculum, and therefore, a rigorous program to support their training is necessary. Methods: The I-PASS Handoff champion training materials were created for the original I-PASS Study and adapted for the Society of Hospital Medicine (SHM) I-PASS Mentored Implementation Program. The adapted materials embrace a flipped classroom approach and adult learning theory. The training includes an overview of I-PASS handoff techniques, an opportunity to practice evaluating handoffs with the I-PASS observation tools using a handoff video vignette, and other key implementation principles. Results: As part of the SHM I-PASS Mentored Implementation Program, 366 champions were trained at 32 sites across North America and participated in a total of 3,491 handoff observations. A total of 346 champions completed the I-PASS Champion Workshop evaluation form at the end of their training (response rate: 94.5%). After receiving the training, over 90% agreed/strongly agreed that it provided them with knowledge or skills critical to their patient care activities and that they were able to distinguish the difference between high- and poor-quality handoffs, competently use the I-PASS handoff assessment tools, and articulate the importance of handoff observations. Conclusion: The I-PASS champion training materials were rated highly by those trained and are an integral part of a successful I-PASS Handoff Program implementation.

Introduction of a pediatric palliative care curriculum for pediatric residents.

INTRODUCTION: The Pediatric Palliative Care Curriculum (PPCC) was introduced as a pilot study in response to the published need for increased pediatric education in end-of-life (EOL) care. The PPCC was designed to better train residents in EOL issues so they could become more comfortable and knowledgeable in caring for children and adolescents with life-threatening illnesses. METHOD: The PPCC consisted of six hour-long sessions run by a clinical psychologist, a licensed social worker, and faculty with experience in EOL care. The curriculum repeated every 6 weeks for 1 year. Residents in the training program at Stanford University rotating through oncology, pulmonology, and pediatric intensive care unit (PICU) were invited to attend. Session topics included: (1) personal coping skills, (2) being a caring professional, (3) recognizing cultural and familial differences, (4) pain management, (5) practical issues, and (6) meeting a bereaved parent. Pretest and posttest surveys with five-point Likert scale questions were used to measure curricular impact. RESULTS: Statistically significant improvement was found in resident self-report of: feeling prepared to initiate do-not-resuscitate discussions (p

Global health training for pediatric residents.

The FOPO Global Health Working Group concludes that global health experiences are important for pediatric residency training and offers five recommendations: 1) There is a need to articulate clearly the rationale supporting the creation of global health experiences in pediatric residency programs. 2) A core curriculum needs to be established for a consistent and meaningful educational experience. The curriculum should include the underlying principles discussed above and should engage representatives from potential host countries in the development of the curriculum. 3) Promoting the opportunity for a global health experience in all residency programs will require a collaborative effort across programs, perhaps at the national level through the Association of Pediatric Program Directors or through the already established Global Health Education Consortium (GHEC).34 A clearinghouse for curricula and for host organizations/institutions both abroad and within the United States and Canada should be established. 4) Global health training needs to be studied rigorously, and lessons learned should be shared. 5) Pediatric residency programs should respect the rights, autonomy, and confidentiality of patients and families in clinical care, research, and operational programs. The FOPO Global Health Working Group looks forward to serving as a focal point to promote discussion on this important issue to the health of our world's children.

I-PASS Handoff Program: Use of a Campaign to Effect Transformational Change.

BACKGROUND: Behavior change is notoriously difficult to achieve within health care systems. Successful implementation of the I-PASS handoff bundle with subsequent decreases in medical errors and preventable adverse events represents an example of successful transformational change within academic medical centers. OBJECTIVE: We designed a campaign to support and enhance uptake of the I-PASS handoff bundle at 9 study sites from 2011 to 2013. METHODS: Following Kotter's model of transformational change, we established urgency using local data and institutional mandates, and site leaders built local guiding coalitions with institutional leaders, key faculty, and Chief Residents. We created and communicated our vision using a branded campaign and empowered others to act by soliciting and acting on feedback and supporting systems changes. Site leaders planned for and created short-term wins by recognizing residents who engaged with I-PASS, consolidated improvements, and institutionalized new approaches. RESULTS: Implementation of I-PASS was successful, with achievement of substantial improvements in rates of medical errors and preventable adverse events. Data from the initial I-PASS study have continued to drive a national campaign that has included national recognition by leaders in the field of patient safety and pediatrics. Momentum has increased significantly to support mentored implementation of the I-PASS handoff program at over 35 academic medical centers across North America. CONCLUSIONS: I-PASS provides an example of transformational change achieved through a combination of educational interventions and change management to address resistance/barriers, supported by a robust campaign. We encourage others in academic medicine to consider using change models, including campaigns, to support health care improvement programs.
