Intracerebral hemorrhage (ICH) is a subtype of stroke that results from spontaneous nontraumatic bleeding into the parenchyma of the brain. ICH accounts for 10% to 15% of all strokes and carries a disproportionately high risk of early death and long-term disability.1 Evidence for optimal treatment of ICH has lagged behind that for ischemic stroke, and con- sequently, metrics specific to ICH care have not been widely promulgated. However, numerous more recent studies and clinical trials of various medical and surgical interventions for ICH have been published and form the basis of evidence-based guidelines for the management of ICH that have been devel- oped by the American Heart Association (AHA)/American Stroke Association (ASA) and other international organiza- Thus, the translation of these guidelines into action- able performance measures is a priority to improve the delivery of care and to improve outcomes for patients with ICH. A clinical performance measure is defined by the Agency for Healthcare Research and Quality as a mechanism for assessing the degree to which a provider competently and safely delivers the appropriate clinical services to the patient within the optimal time period. 5 Performance measures are being increasingly used for quality improvement, exter- nal reporting, regulatory oversight by hospital and program accreditation groups, and possibly pay-for-performance pro- Performance measures differ from guidelines in that most rigorous guidelines describe a desirable treatment or pro- cess of care that is derived from a review of existing medical evidence using standardized criteria and levels of evidence.7 However, guidelines traditionally do not take the next step of describing specifically how their implementation will be assessed in a quantitative way in order to assess compliance.
