Text: the authors confirm that, for approved reasons, some access restrictions apply to the data underlying the findings. the ahrq sid is available to the public through the ahrq healthcare cost utilization project central distributor (http://www.hcup-us.ahrq.gov/tech_assist/centdist.jsp). however, this analysis uses the ahrq sid intramural database which provides access to additional states and years of data. hcup state inpatient data intramural versions are restricted access, confidential, record-level data that can only be made available to authorized ahrq staff, their contractors, and authorized on-site guest researchers. the data are made available to the agency for healthcare research and quality (ahrq) through a collaboration with state data organizations; the data access are governed by a memorandum of agreement (moa) negotiated between the state data organizations and the agency for healthcare research and quality (ahrq). the intramural version of the database was available for this analysis through an interagency agreement between the national institutes of health and ahrq. researchers must therefore contact each state to request access to the state inpatient data: http://www.hcup-us.ahrq.gov/partners.jsp.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
