Blood Conservation and Hemostasis in Cardiac Surgery: A Survey of Practice Variation and Adoption of Evidence-Based Guidelines.

BACKGROUND: Blood conservation and hemostasis are integral parts of reducing avoidable blood transfusions and the associated morbidity and mortality. Despite the publication of blood conservation guidelines for cardiac surgery, evidence suggests persistent variability in practice patterns. Members of the Society of Cardiovascular Anesthesiologists (SCA) created a survey to audit conformance to existing guidelines and use the results to help narrow the evidence-to-practice gap. METHODS: Members of the SCA and its Continuous Practice Improvement (CPI)- Blood Conservation Work Group developed a 48-item Blood Conservation and Hemostasis in Cardiac Surgery (BCHCS) survey. The questionnaire included the components of the Anesthesia Quality Institute's (AQI) composite measure AQI49. The survey was distributed to the entire SCA membership by e-mail via the Research Electronic Data Capture (REDCap) Consortium between the fall of 2017 and early 2018. RESULTS: Of 3152 SCA members, 536 returned surveys for a response rate of 17%. Most responders worked at academic institutions. The median transfusion trigger after cardiopulmonary bypass was hemoglobin (Hgb) 7.0 to 8.0 g/dL. There are 4 components to AQI49, and the composite conformance to all of them was low due to 1 specific component: the use of transfusion algorithms supplemented with point-of-care (POC) testing. There was good conformance to the other 3 components of AQI49: use of antifibrinolytics, minimization of hemodilution and use of red cell salvage. Overall, practices with a multidisciplinary patient blood management (PBM) team were the most successful in meeting all 4 AQI49 criteria. CONCLUSIONS: The survey demonstrated widespread adoption of several best practices, including the tolerance of lower hemoglobin transfusion triggers, use of antifibrinolytics, minimization of hemodilution, and use of red cell salvage. The survey also confirms that gaps remain in preoperative anemia management and the use of transfusion algorithms supplemented with POC hemostasis testing. Serial use of this survey can be used to identify barriers to implementation and audit the effectiveness of interventions described in this article. This instrument could also help harmonize local, regional, and national efforts and become an essential component of an implementation strategy for PBM in cardiac surgery.

Improving handover competency in preclinical medical and health professions students: establishing the reliability and construct validity of an assessment instrument.

BACKGROUND: As part of the worldwide call to enhance the safety of patient handovers of care, the Association of American Medical Colleges (AAMC) requires that all graduating students "give or receive a patient handover to transition care responsibly" as one of its Core Entrustable Professional Activities (EPAs) for Entering Residency. Students therefore require educational activities that build the necessary teamwork skills to perform structured handovers. To date, a reliable instrument designed to assess teamwork competencies, like structured communication, throughout their preclinical and clinical years does not exist. METHOD: Our team developed an assessment instrument that evaluates both the use of structured communication and two additional teamwork competencies necessary to perform safe patient handovers. This instrument was utilized to assess 192 handovers that were recorded from a sample of 229 preclinical medical students and 25 health professions students who participated in a virtual course on safe patient handovers. Five raters were trained on utilization of the assessment instrument, and consensus was established. Each handover was reviewed independently by two separate raters. RESULTS: The raters achieved 72.22 % agreement across items in the reviewed handovers. Krippendorff's alpha coefficient to assess inter-rater reliability was 0.6245, indicating substantial agreement among the raters. A confirmatory factor analysis (CFA) demonstrated the orthogonal characteristics of items in this instrument with rotated item loadings onto three distinct factors providing preliminary evidence of construct validity. CONCLUSIONS: We present an assessment instrument with substantial reliability and preliminary evidence of construct validity designed to evaluate both use of structured handover format as well as two team competencies necessary for safe patient handovers. Our assessment instrument can be used by educators to evaluate learners' handoff performance as early as their preclinical years and is broadly applicable in the clinical context in which it is utilized. In the journey to optimize safe patient care through improved teamwork during handovers, our instrument achieves a critical step in the process of developing a validated assessment instrument to evaluate learners as they seek to accomplish this goal.

Society of Cardiovascular Anesthesiologists Clinical Practice Improvement Advisory for Management of Perioperative Bleeding and Hemostasis in Cardiac Surgery Patients.

Bleeding after cardiac surgery is a common and serious complication leading to transfusion of multiple blood products and resulting in increased morbidity and mortality. Despite the publication of numerous guidelines and consensus statements for patient blood management in cardiac surgery, research has revealed that adherence to these guidelines is poor, and as a result, a significant variability in patient transfusion practices among practitioners still remains. In addition, although utilization of point-of-care (POC) coagulation monitors and the use of novel therapeutic strategies for perioperative hemostasis, such as the use of coagulation factor concentrates, have increased significantly over the last decade, they are still not widely available in every institution. Therefore, despite continuous efforts, blood transfusion in cardiac surgery has only modestly declined over the last decade, remaining at ≥50% in high-risk patients. Given these limitations, and in response to new regulatory and legislature requirements, the Society of Cardiovascular Anesthesiologists (SCA) has formed the Blood Conservation in Cardiac Surgery Working Group to organize, summarize, and disseminate the available best-practice knowledge in patient blood management in cardiac surgery. The current publication includes the summary statements and algorithms designed by the working group, after collection and review of the existing guidelines, consensus statements, and recommendations for patient blood management practices in cardiac surgery patients. The overall goal is creating a dynamic resource of easily accessible educational material that will help to increase and improve compliance with the existing evidence-based best practices of patient blood management by cardiac surgery care teams.

Effects of red-cell storage duration on patients undergoing cardiac surgery.

BACKGROUND: Some observational studies have reported that transfusion of red-cell units that have been stored for more than 2 to 3 weeks is associated with serious, even fatal, adverse events. Patients undergoing cardiac surgery may be especially vulnerable to the adverse effects of transfusion. METHODS: We conducted a randomized trial at multiple sites from 2010 to 2014. Participants 12 years of age or older who were undergoing complex cardiac surgery and were likely to undergo transfusion of red cells were randomly assigned to receive leukocyte-reduced red cells stored for 10 days or less (shorter-term storage group) or for 21 days or more (longer-term storage group) for all intraoperative and postoperative transfusions. The primary outcome was the change in Multiple Organ Dysfunction Score (MODS; range, 0 to 24, with higher scores indicating more severe organ dysfunction) from the preoperative score to the highest composite score through day 7 or the time of death or discharge. RESULTS: The median storage time of red-cell units provided to the 1098 participants who received red-cell transfusion was 7 days in the shorter-term storage group and 28 days in the longer-term storage group. The mean change in MODS was an increase of 8.5 and 8.7 points, respectively (95% confidence interval for the difference, -0.6 to 0.3; P=0.44). The 7-day mortality was 2.8% in the shorter-term storage group and 2.0% in the longer-term storage group (P=0.43); 28-day mortality was 4.4% and 5.3%, respectively (P=0.57). Adverse events did not differ significantly between groups except that hyperbilirubinemia was more common in the longer-term storage group. CONCLUSIONS: The duration of red-cell storage was not associated with significant differences in the change in MODS. We did not find that the transfusion of red cells stored for 10 days or less was superior to the transfusion of red cells stored for 21 days or more among patients 12 years of age or older who were undergoing complex cardiac surgery.

The Society of Thoracic Surgeons, The Society of Cardiovascular Anesthesiologists, and The American Society of ExtraCorporeal Technology: Clinical Practice Guidelines-Anticoagulation During Cardiopulmonary Bypass.

Despite more than a half century of "safe" cardiopulmonary bypass (CPB), the evidence base surrounding the conduct of anticoagulation therapy for CPB has not been organized into a succinct guideline. For this and other reasons, there is enormous practice variability relating to the use and dosing of heparin, monitoring heparin anticoagulation, reversal of anticoagulation, and the use of alternative anticoagulants. To address this and other gaps, The Society of Thoracic Surgeons, the Society of Cardiovascular Anesthesiologists, and the American Society of Extracorporeal Technology developed an Evidence Based Workgroup. This was a group of interdisciplinary professionals gathered to summarize the evidence and create practice recommendations for various aspects of CPB. To date, anticoagulation practices in CPB have not been standardized in accordance with the evidence base. This clinical practice guideline was written with the intent to fill the evidence gap and to establish best practices in anticoagulation therapy for CPB using the available evidence. To identify relevant evidence, a systematic review was outlined and literature searches were conducted in PubMed using standardized medical subject heading (MeSH) terms from the National Library of Medicine list of search terms. Search dates were inclusive of January 2000 to December 2015. The search yielded 833 abstracts, which were reviewed by two independent reviewers. Once accepted into the full manuscript review stage, two members of the writing group evaluated each of 286 full papers for inclusion eligibility into the guideline document. Ninety-six manuscripts were included in the final review. In addition, 17 manuscripts published before 2000 were included to provide method, context, or additional supporting evidence for the recommendations as these papers were considered sentinel publications. Members of the writing group wrote and developed recommendations based on review of the articles obtained and achieved more than two thirds agreement on each recommendation. The quality of information for a given recommendation allowed assessment of the level of evidence as recommended by the American College of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines. Recommendations were written in the three following areas: (1) heparin dosing and monitoring for initiation and maintenance of CPB; (2) heparin contraindications and heparin alternatives; and (3) reversal of anticoagulation during cardiac operations. It is hoped that this guideline will serve as a resource and will stimulate investigators to conduct more research and to expand on the evidence base on the topic of anticoagulation therapy for CPB.

Protocol adherence when managing massive bleeding following complex cardiac surgery: a study design pilot.

OBJECTIVE: High-quality prospective trials of hemostatic "rescue" therapy to control massive bleeding in cardiac surgery are lacking. Wide variability in the care of patients with severe bleeding following cardiopulmonary bypass has precluded accurate comparison of treatment groups in previous studies. This study identified the use of a management protocol for early identification and uniform treatment of patients with massive bleeding for application in future trials of hemostatic rescue agents. DESIGN: A prospective, nonblinded, interventional feasibility study. SETTING: A university teaching hospital. PARTICIPANTS: Forty-three adult patients undergoing complex cardiac surgery. INTERVENTIONS: Study participants undergoing high-risk cardiac surgery received standardized treatment in accordance with a bleeding management protocol. MEASUREMENTS AND MAIN RESULTS: Twenty-seven patients (63%) had severe bleeding following heparin reversal and received conventional hemostatic resuscitation per protocol. Six patients had massive refractory bleeding. Compliance with protocol tasks was≥90% in 4 of 5 categories (anticoagulation, hemostasis scoring, recording blood loss, protocol transfusion) with the exception being submission of laboratory samples (76%). Measured bleeding rates (mL/h) following heparin reversal were clearly differentiated in those with hemostasis scores≥3 compared to those with scores≤2 (1,420±957 v 147±96; p<0.001). CONCLUSIONS: Adherence to a management protocol for massive bleeding is feasible and allows for homogenous treatment of patients before study arm randomization in future "rescue" therapy trials. The authors' protocol allowed for prompt and accurate identification of patients with severe bleeding refractory to conventional therapy. This review resolved several key barriers in the design of severe bleeding management trials.

An evidence synthesis on perioperative Handoffs: A call for balanced sociotechnical solutions.

SIGNIFICANCE: Perioperative handoffs interconnect the preoperative, intraoperative, and postoperative phases underlying surgical care to maintain care continuity -yet are prone to coordination and communication failures. OBJECTIVE: To synthesize evidence on factors affecting the safety and quality of perioperative handoff conduct and process. MATERIALS AND METHODS: A search of PubMed, EMBASE, and CINAHL was conducted to include observational, descriptive studies of preoperative, intraoperative, and postoperative handoffs published in English language, peer-reviewed journals. Data analysis was informed by the Systems Engineering Initiative for Patient Safety (SEIPS) framework describing the relationship between the work-system, work processes, and outcomes. Study quality was assessed using the Quality Scoring System. RESULTS: Twenty-three studies were included. Eighteen studies focused on postoperative handoffs, with one on preoperative, three on intraoperative and only one that looked at preoperative/postoperative handoffs combined. The SEIPS framework elucidated the complex inter-related factors (enablers and barriers) related to perioperative handoff safety. While some studies found that the use of standardized handoff tools and protocols and interdisciplinary teamwork were frequently-reported enablers, other studies identified the lack of structured handoff tools and protocols, poor teamwork and communication, and improper use of documentation tools were top-cited barriers affecting handoff quality. Suggestions to ensure handoff safety and quality included implementing structured handoff checklists and protocols and building interprofessional teamwork competencies for effective communication. DISCUSSION AND CONCLUSION: Our review highlights an urgency to develop more holistic sociotechnical solutions that can create and sustain a balance between technical innovations in tools and technologies and the non-technical interventions/training needed to improve interpersonal relations and teamwork competencies - taken together, can improve the quality and safety of perioperative handoff practice.

Opportunities to apply systems engineering to healthcare interprofessional education.

In medical settings, interprofessional education (IPE) plays an important role by bringing students from multiple disciplines together to learn how to collaborate effectively and coordinate safe patient care. Yet developing effective IPE is complex, considering that stakeholders from different schools and programs are involved, each with varying curriculum requirements and interests. Given its critical importance and inherent complexity, innovative approaches to address these challenges are needed to effectively develop and sustain effective IPE programs. Systems engineering (SE) combines a lifecycle perspective with established interdisciplinary processes to develop and sustain large complex systems. The need for SE approaches to manage healthcare complexity has been recognized, but the application of SE to IPE programs has been limited. We believe that there is a significant opportunity for IPE programs to benefit from the application of SE. The common themes running through SE and IPE led us to ask if SE can be used to address IPE complexity and achieve desired IPE outcomes. We believe that SE could facilitate further development and sustainability of a recently developed healthcare curriculum. We also propose to use SE to accelerate and manage future IPE curriculum development, while better understanding the states of vital IPE-related components. We discuss a framework that considers transitions of key IPE elements. We believe that use of interdisciplinary SE processes and holistic perspectives and methods such as system thinking will improve the management of system challenges while addressing IPE's inherent complexity and leading to better patient outcomes and more effective interprofessional collaboration.

Handoffs and the challenges to implementing teamwork training in the perioperative environment.

Perioperative handoffs are high-risk events for miscommunications and poor care coordination, which cause patient harm. Extensive research and several interventions have sought to overcome the challenges to perioperative handoff quality and safety, but few efforts have focused on teamwork training. Evidence shows that team training decreases surgical morbidity and mortality, and there remains a significant opportunity to implement teamwork training in the perioperative environment. Current perioperative handoff interventions face significant difficulty with adherence which raises concerns about the sustainability of their impact. In this perspective article, we explain why teamwork is critical to safe and reliable perioperative handoffs and discuss implementation challenges to the five core components of teamwork training programs in the perioperative environment. We outline evidence-based best practices imperative for training success and acknowledge the obstacles to implementing those best practices. Explicitly identifying and discussing these obstacles is critical to designing and implementing teamwork training programs fit for the perioperative environment. Teamwork training will equip providers with the foundational teamwork competencies needed to effectively participate in handoffs and utilize handoff interventions. This will improve team effectiveness, adherence to current perioperative handoff interventions, and ultimately, patient safety.

Holistic strategy for promoting effective handoffs.

BACKGROUND: Handoffs are ubiquitous in modern healthcare practice, and they can be a point of resilience and care continuity. However, they are prone to a variety of issues. Handoffs are linked to 80% of serious medical errors and are implicated in one of three malpractice suits. Furthermore, poorly performed handoffs can lead to information loss, duplication of efforts, diagnosis changes and increased mortality. METHODS: This article proposes a holistic approach for healthcare organisations to achieve effective handoffs within their units and departments. RESULTS: We examine the organisational considerations (ie, the facets controlled by higher-level leadership) and local drivers (ie, the aspects controlled by the individuals working in the units and providing patient care). CONCLUSION: We propose advice for leaders to best enact the processes and cultural change necessary to see positive outcomes associated with handoffs and care transitions within their units and hospitals.

Team FIRST framework: Identifying core teamwork competencies critical to interprofessional healthcare curricula.

Interprofessional healthcare team function is critical to the effective delivery of patient care. Team members must possess teamwork competencies, as team function impacts patient, staff, team, and healthcare organizational outcomes. There is evidence that team training is beneficial; however, consensus on the optimal training content, methods, and evaluation is lacking. This manuscript will focus on training content. Team science and training research indicates that an effective team training program must be founded upon teamwork competencies. The Team FIRST framework asserts there are 10 teamwork competencies essential for healthcare providers: recognizing criticality of teamwork, creating a psychologically safe environment, structured communication, closed-loop communication, asking clarifying questions, sharing unique information, optimizing team mental models, mutual trust, mutual performance monitoring, and reflection/debriefing. The Team FIRST framework was conceptualized to instill these evidence-based teamwork competencies in healthcare professionals to improve interprofessional collaboration. This framework is founded in validated team science research and serves future efforts to develop and pilot educational strategies that educate healthcare workers on these competencies.

Leveraging the Science of Teamwork to Sustain Handoff Improvements in Cardiovascular Surgery.

BACKGROUND: Improving the reliability of handoffs and care transitions is an important goal for many health care organizations. Increasing evidence shows that human-centered design and improved teamwork can lead to sustainable care transition improvements and better patient outcomes. This study was conducted within a cardiovascular service line at an academic medical center that performs more than 600 surgical procedures annually. A handoff process previously implemented at the center was poorly adopted. This work aimed to improve cardiovascular handoffs by applying human factors and the science of teamwork. METHODS: The study's quality improvement method used Plan-Do-Study-Act cycles and participatory design and ergonomics to develop, implement, and assess a new handoff process and bundle. Trained observers analyzed video-recorded and live handoffs to assess teamwork, leadership, communication, coordination, cooperation, and sustainability of unit-defined handoff best practices. The intervention included a teamwork-focused redesign process and handoff bundle with supporting cognitive aids and assessment metrics. RESULTS: The study assessed 153 handoffs in multiple phases over 3 years (2016-2019). Quantitative and qualitative assessments of clinician (teamwork) and implementation outcomes were performed. Compared with the baseline, the observed handoffs demonstrated improved team leadership (p < 0.0001), communication (p < 0.0001), coordination (p = 0.0018), and cooperation (p = 0.007) following the deployment of the handoff bundle. Sustained improvements in fidelity to unit-defined handoff best practices continued 2.3 years post-deployment of the handoff bundle. CONCLUSION: Participatory design and ergonomics, combined with implementation and safety science principles, can provide an evidence-based approach for sustaining complex sociotechnical change and making handoffs more reliable.

Handoffs and Teamwork: A Framework for Care Transition Communication.

BACKGROUND: Handoffs occur frequently in the medical domain and are associated with up to 80% of medical errors. Although research has progressed, handoffs largely remain inadequate. The absence of an appropriate conceptual model for handoffs hinders the purposeful design and evaluation of handoff procedures. This article presents a theoretical model of the major input, team process, and output variables that should be considered during a handoff. THEORETICAL MODEL BACKGROUND: The model integrates three theoretical frameworks that capture the various inputs, processes, and outputs surrounding handoff events through the lens of teamwork. OVERVIEW OF THE MODEL: Specifically, the model describes the environment, organization, people, and tools as inputs. Communication, leadership, coordination, and decision making serve as the processes, and the outputs are the organization, teams, providers, and patients.

A Collaborative Partnership between the Multicenter Handoff Collaborative and an Electronic Health Record Vendor.

OBJECTIVES: The operating room is a specialized, complex environment with many factors that can impede effective communication during transitions of care between anesthesia clinicians. We postulated that an efficient, accessible, standardized tool for intraoperative handoffs built into standard workflow would improve communication and handoff safety. Most institutions now use an electronic health record (EHR) system for patient care and have independently designed intraoperative handoff tools, but these home-grown tools are not scalable to other organizations and lack vendor-supported features. The goal of this project was to create a standardized, intraoperative handoff tool supported by EHR functionality. METHODS: The Multicenter Handoff Collaborative, with support from the Anesthesia Patient Safety Foundation, created a working group of frontline anesthesia experts to collaborate with a development team from the EHR vendor (Epic Systems) to design a standardized intraoperative handoff tool. Over 2 years, the working group identified the critical elements for the tool and software usability, and the EHR team designed a standardized intraoperative handoff tool that is accessible to any institution using this EHR. RESULTS: The first iteration of the intraoperative handoff tool was released in August 2019, with a second version in February 2020. The tool is standardized but customizable by individual institutions. CONCLUSION: We demonstrate that work on complex health care processes critical to patient safety, such as handoffs, can be performed on a national scale through cross-industry collaboration. Frontline experts can partner with health care industry vendors to design, build, and release a product on an accelerated timeline.
