Standardized protocols Goal: optimize care Emerging Evidence – Pathways work: –CHAMP –Guidelines Applied in Practice (GAP) –AHA “Get with the Guidelines” program

National Heart Attack Alert Program (NHAAP) CRITICAL PATHWAYS FOR THE TREATMENT OF PATIENTS WITH ACUTE CORONARY SYNDROMES

18 Critical Pathways - Definitions Standardized protocols for care Strict definition –Full list of all tasks, tracks variances Broader definition –Includes clinical protocols (NHAAP 4D’s) Diagnostic pathways - Chest Pain Centers Treatment pathways - Thrombolysis

19 Goals of Critical Pathways Increase use of recommended medical therapies (e.g., aspirin) Decrease use of unnecessary tests. Decrease hospital length of stay Increase participation in clinical research Improve patient care and decrease costs.

20 Need and Rationale for Critical Pathways Underutilization of recommended medications (e.g. Aspirin) Overutilization of procedures Length of stay, # ICU days Quality of care measures (door-to-drug, door-to-balloon times)

21 Development And Implementation Of Critical Pathways Identify problems ( practice variation) Identify working committee/task force to develop path Distribute draft Critical Pathway to all personnel and departments involved. Revise based on approach. Implement pathway Collect and monitor data on pathway performance. Modify the pathway as needed to further improve performance.

22 Methods of Implementation of Pathways Specific case manager for each Pt –High compliance, high cost Standardized order sheets, Pocket guides “Championing” - Grand rounds Recent study -> similar improvements in care with either formal or simpler pathways (Holmboe, ES et al. Am J Med 1999;107: )

27 Guidelines Applied in Practice (GAP) Launched by ACC in February 2000 to: –Bridge gap between ideal therapy and treatment practice –Create/implement guideline tools/processes Initial project: –Michigan hospitals –Implemented 1999 ACC/AHA AMI Guideline –Determine whether quality of care can be improved via guideline tools –Status: pilot completed, expansion now in progress Mehta R, et al.

31 Importance of Data-Collection Registries Track adherence to guidelines Support local quality-improvement programs Compare practice patterns/outcomes with benchmarks Comply with regulatory requirements Provide research data Major Data-Collection Registries –NRMI –AHA Get With the Guidelines –ACC NCDR –GRACE –CRUSADE –VA transformation

32 VA Transformation - Methods 1995, VA launched a major reengineering of its health care system with aims that included: –Better use of information technology, –measurement and reporting of performance, –and integration of services –and realigned payment policies.

VA Transformation - Results

34 Conclusions Critical pathways hold great promise to improve –Quality of care, –Clinical outcomes –Cost-effectiveness Initial studies show better quality of care and suggest improved outcomes
