Evolution of an Evidence Collaboration: From Initial Goals to Current Initiatives.

Best practices based on evidence are needed by every clinician to provide safe, effective, patient-centered care. Determining best practice for a given situation can be difficult. Ideally, the clinician understands how to critically appraise the relevant research, and integrates high-quality research with interdisciplinary clinical expertise and patient and family values and preferences to choose best care for an individual or family. At our organization, we are taking the integration of research, clinical expertise, and patient/family preferences and values to the next level by aligning the evidence work of multiple functional areas and disciplines to improve the safety and effectiveness of clinical practice. The Evidence Collaboration, an interdisciplinary community of practice, has evolved to meet the challenges of helping novices and experts of all disciplines identify, critically appraise, synthesize, and disseminate evidence to inform best practices for patients and families, staff, and institutional processes. By creating a common language for evidence work, resources such as the Let Evidence Guide Every New Decision system, and templates for dissemination, the Evidence Collaboration has moved the organizational culture toward one that encourages the use of evidence in all decisions. Our progress continues as we strive to include patients and families in the decisions about best practices based on evidence.

Venous thromboembolism in hospitalized adolescents: an approach to risk assessment and prophylaxis.

BACKGROUND: Pediatric hospital-acquired venous thromboembolism (VTE) is an increasingly prevalent and morbid disease. A multidisciplinary team at a tertiary children's hospital sought to answer the following clinical question: "Among hospitalized adolescents, does risk assessment and stratified VTE prophylaxis compared with no prophylaxis reduce VTE occurrence without an increase in significant adverse effects?" METHODS: Serial literature searches using key terms were performed in the following databases: Medline, Cochrane Database, CINAHL (Cumulative Index to Nursing and Allied Health), Scopus, EBMR (Evidence Based Medicine Reviews). Pediatric studies were sought preferentially; when pediatric evidence was sparse, adult studies were included. Abstracts and titles were screened, and relevant full articles were reviewed. Studies were rated for quality using a standard rating system. RESULTS: Moderate evidence exists to support VTE risk assessment in adolescents. This evidence comes from pediatric studies that are primarily retrospective in design. The results of the studies are consistent and cite prominent factors such as immobilization and central venous access. There is insufficient evidence to support specific prophylactic strategies in pediatric patients because available pediatric evidence for thromboprophylaxis efficacy and safety is minimal. There is, however, high-quality, consistent evidence demonstrating efficacy and safety of thromboprophylaxis in adults. CONCLUSIONS: On the basis of the best available evidence, we propose a strategy for risk assessment and stratified VTE prophylaxis for hospitalized adolescents. This strategy involves assessing risk factors and considering prophylactic measures based on level of risk. We believe this strategy may reduce risk of VTE and appropriately balances the adverse effect profile of mechanical and pharmacologic prophylactic methods.

Reducing risk of harm from extravasation: a 3-tiered evidence-based list of pediatric peripheral intravenous infusates.

Extravasation of medications during peripheral intravenous (PIV) therapy can result in harm to pediatric patients. These medications have physical and/or biologic factors that cause tissue damage. To assist in clinical decisions when using these infusates, an evidence-based table of medications stratified by their relative risk of causing harm if extravasated was developed. Local data and experience, a systematic review of the pediatric literature, and measured pH and osmolality of common pediatric preparations of PIV infusates were used to create a 3-tiered table of PIV infusates categorized by relative risk of causing harm if extravasated.

The development of evidence-based care recommendations to improve the safe use of anticoagulants in children.

Evidence-based care recommendations and standardized protocols improve outcomes. In addition, anticoagulant management has been recognized by The Joint Commission (TJC) as an opportunity for improving patient safety. A National Patient Safety Goal requiring a standardized process for patients receiving anticoagulants was established by TJC. This requirement provided an opportunity to apply evidence-based care recommendations to the issue of safe anticoagulant use. To meet TJC requirement, the following searchable clinical question was drafted: "In children receiving anticoagulation therapy, what are the appropriate dosing, laboratory monitoring, timing, and dosing adjustments for warfarin, unfractionated heparin, and low-molecular-weight heparin to prevent coagulation-related complications?" The team used the Appraisal of Guidelines Research and Evaluation Collaboration (AGREE) instrument to evaluate the quality and relevance of identified guidelines in answering the clinical question. Best Evidence Statements (BESts) were developed for each of the medications (warfarin, low-molecular-weight heparin, and unfractionated heparin). BESts provide the format for the presentation of recommendations, discussion, and methods for point-of-care providers seeking synthesized evidence to guide care decisions. The primary goal of developing and implementing these statements was to standardize the use of anticoagulants and to prevent unsafe practices. A secondary goal was to ensure accessibility of the BESts throughout our organization, including the electronic medical record, various internal division home pages, and our organization's external website. The anticoagulant BESts developed at our organization show how an interprofessional approach to patient care results in the development of evidence-based care recommendations. The BESts were developed to standardize care associated with the use of anticoagulants and to provide dosing and monitoring parameters to ensure safe care to all patients receiving these medications. The development of evidence-based care recommendations can be accomplished with a focused interprofessional team dedicated to providing the safest possible care to patients.

Let Evidence Guide Every New Decision (LEGEND): an evidence evaluation system for point-of-care clinicians and guideline development teams.

OBJECTIVE: To develop tools for use by teams of point-of-care clinicians to improve access to evidence evaluation. METHOD: A search of the literature was conducted to review available evidence evaluation systems for their applicability to the project. Fourteen systems were reviewed in depth for strengths and limitations of the systems to meet the objective. Using these strengths and addressing the limitations, tools were developed and pilot-tested among an interprofessional team of clinicians. Results Five principles were drawn from the review of the literature and from our experience to guide development of six tools. The tools form a comprehensive evidence evaluation system known as Let Evidence Guide Every New Decision (LEGEND). LEGEND included a glossary, a table of evidence levels, an algorithm, a set of evidence appraisal forms, and worksheets to guide grading a body of evidence and judging the strength of a recommendation. CONCLUSION: LEGEND provides tools for point-of-care clinicians that assist them in synthesizing evidence from published studies. The tools provide a balance between quality processes and simplicity, use terminology friendly to multiple disciplines, assist comprehensively with the evidence evaluation process, incorporate factors familiar to the user, and provide flexibility for a diverse range of evidence evaluation projects and users.
