As with acute ischemic stroke, it is recognized that there are multiple dimensions of care for ICH, including the prehospital setting, the emergency depart- ment, rehabilitation, and outpatient care directed at primary and secondary prevention. Most other stroke-related performance measures (such as those from TJC,13 AHA s Get With The the the CDC s Paul Coverdell National Acute Stroke Program,15 and the AHA/ASA ischemic stroke ) have used the inpatient setting for this purpose because it represents a well-identified period of care that generally has good documentation of patient parameters and administered treatments as part of the medical record.16 However, it is recognized that there are elements relevant to the care of patients with ICH that are not sufficiently captured by the use of the inpatient setting such as administration of longer- term rehabilitation and interventions focusing on prevention such as long-term blood pressure control. The writing group discussed the feasibility of assessment of performance measures in various settings and felt that restricting the dimension of care to the acute inpatient setting was a reasonable compromise for this first set of ICH performance measures. It was felt important that all hospitals involved in the acute care of patients with ICH should be considered under these performance measures; thus, they apply to hospitals that might transfer a patient with ICH after initial assessment or receive that patient in transfer after initial stabilization at another acute care hospital. In addition, it would be most desirable for performance measures to be directly linked to patient-specific outcomes as opposed to processes of care.17 Outcomes can be intermediate- term or acute outcomes (eg, development of pneumonia during the inpatient setting) or long-term outcomes (eg, functional out- come at 6 months after ICH or recurrence of ICH in the years after the initial event).
