2 AHA/ASA Guidelines for Adult Stroke Rehabilitation and Recovery were also reviewed.18 In addition, other documents of existing performance measures or quality metrics were reviewed to assess whether there were current performance measures developed for ischemic stroke or ICH that should be considered for inclusion and harmonization. The AHA/ASA Metrics for Measuring Quality of Care in Comprehensive Stroke Centers and Clinical Performance Measures for Adults Hospitalized With Acute Ischemic Stroke were reviewed for potential measures that would apply to ICH and should be considered for inclusion.10,19 Currently active per- formance measures from other organizations, including TJC, the CDC s Paul Coverdell National Acute Stroke Program, NQF, AHA s Get With The Guidelines Stroke, the American Medical Association-convened Physician Consortium for Performance Improvement, the Centers for Medicare & Medicaid Services Hospital Inpatient Quality Reporting Program, and NQF, were reviewed specifically in terms of whether measures analogous to those proposed here existed in other performance measurement sets currently in use and, if so, to consider harmonization across them when appropriate. Selection and Development of Performance Measures The process for the selection and development of these ICH performance measures used an approach from the AHA/ASA Stroke Performance Oversight Committee similar to that used for the 2014 AHA/ASA ischemic stroke performance mea- Only Class I (high consensus for benefit) and Class III (high consensus for harm) recommendations according to the AHA/ASA criteria for recommendations and classification of Levels of Evidence were considered candidates for develop- ment into performance measures (Supplemental Tables 2 and correspondence to review all Class I and III recommendations from the 2015 AHA/ASA ICH guidelines for suitability to develop into performance measures.
