Transparency matters: Kaiser Permanente's National Guideline Program methodological processes.

INTRODUCTION: The practice-guideline process of collecting, critically appraising, and synthesizing available evidence, then developing expert panel recommendations based on appraised evidence, makes it possible to provide high-quality care for patients. Unwanted variability in the quality and rigor of evidence summaries and Clinical Practice Guidelines has been a long-standing challenge for clinicians seeking evidence-based guidance to support patient care decisions. METHODS: A multidisciplinary group of stakeholders, with representation from all eight Kaiser Permanente Regions, is responsible for creating National Guidelines. Conducting high-quality systematic reviews and creating clinical guidelines are time-, labor-, and resource-intensive processes, which raises challenges for an organization striving to balance rigor with efficiency. For these reasons, the National Guideline Program elected to allow for the identification, assessment, and possible adoption of existing evidence-based guidelines and systematic reviews using the ADAPTE; Appraisal of Guidelines Research and Evaluation; Assessment of Multiple Systematic Reviews (AMSTAR); and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) frameworks. If no acceptable external guidelines are identified, the Guideline Development Team then systematically searches for relevant high-quality systematic reviews, meta-analyses, and original studies. Existing systematic reviews are assessed for quality using a measurement tool to assess systematic reviews (the AMSTAR systematic review checklist). STUDY APPRAISAL: Following the screening and selection process, the included studies (the "body of evidence") are critically appraised for quality, using the GRADE methodology, which focuses on four key factors that must be considered when assigning strength to a recommendation: balance between desirable and undesirable effects, quality of evidence, values and preferences, and cost. The evidence is then used to create preliminary clinical recommendations. The strength of these recommendations is graded to reflect the extent to which a guideline panel is confident that the desirable effects of an intervention outweigh undesirable effects (or vice versa) across the range of patients for whom the recommendation is intended. DISSEMINATION: The Care Management Institute disseminates all KP national guidelines to its eight Regions via postings on its Clinical Library Intranet site, a Web-based internal information resource.

Health care delivery performance: service, outcomes, and resource stewardship.

As competition intensifies within the health care industry, patient satisfaction and service quality are providing the evidentiary basis for patient outcomes. We propose a conceptual model of three interrelated areas, service, health outcomes, and resource stewardship, all affected by the clinician-patient relationship. Our model considers the perspectives of the health care organization, the clinician, and the patient to define a more comprehensive measure of health care delivery performance. Research and managerial aspects, including implementation, are discussed.

Integrating herbs and supplements in managed care: a pharmacy perspective.

Herbal and other dietary supplements are popular among patients. Whether and how to establish and manage an herbal formulary remains a challenge for conventional managed-care organizations. Pharmacists and clinicians depend on evidence-based guidelines to help determine which products (whether pharmaceutical or herbal) to make available to patients. Evidence from randomized controlled trials that supports the use of most herbal supplements is scarce, yet for some supplements, credible evidence supports the possibility of efficacy. Quality control remains of concern for the supplement industry and for patients and clinicians considering the use of supplements.Clinicians may improve care by both disseminating educational materials and making available to patients popular quality-controlled herbal supplements deemed safe and effective. Kaiser Permanente Northwest (KPNW) has adopted a comprehensive and systematic approach to managing and stocking herbal supplements that can serve as a model for other conventional and managed care organizations.KPNW's dedicated Natural Products Advisory Committee (NPAC) has made considerable progress toward developing a constructive response to KPNW patients' herbal supplement use. Making supplements available at pharmacies can improve clinical outcomes, patient convenience, and quality control. NPAC currently limits its reviews to randomized, controlled trials and data from meta-analyses and systematic reviews for single-ingredient supplements. As interest in this area maintains steady growth, NPAC will continue to study how best to meet patients' needs.
