Specific guideline rec- ommendations selected were then converted into performance measures by specifying eligible patients through specific inclu- sion and exclusion criteria and the measure numerator and denominator that would allow quantitative reporting of aggre- gate data. Previously existing performance measures that might apply to ICH that were already developed or endorsed by the National Quality Forum (NQF) or other groups such as the Centers for Disease Control and Prevention (CDC) or The Joint Commission (TJC) were also reviewed, and when possible, an attempt was made to harmonize these new AHA/ASA ICH performance measures with those already endorsed. Draft ICH performance measures were released for public comment.After the close of the public comment period, these comments were reviewed by the writing group, and the performance measures were revised as deemed appropriate. New measures deserve pilot testing before widespread adoption. Structure and Membership of the Writing Group The writing group was selected by the AHA/ASA Stroke Performance Oversight Committee and was designed to include a diverse set of experienced clinicians with expertise in both the guideline-concordant management of ICH and performance measure development. Represented specialties included vascular neurology, neurosurgery, neurocritical care, neuroendovascular care, physical medicine and rehabilitation, cardiology, hematology, emergency medicine, public health, and nursing. AHA staff members provided administrative assistance and direction for the process but were not involved directly in selecting the specific performance measures. Work was conducted via multiple confidential conference calls and e-mail; in-person writing group meetings did not occur. Disclosure of Relationships With Industry All members of the writing group were volunteers who donated their time and efforts without monetary or other com- pensation. Writing group members were required to disclose in writing all financial relationships with industry relevant to this topic according to standard AHA reporting policies.
