Section 5.07 - Requests for Summarized Data Reports

(1) Applicants may request a report generated by CHIA that is derived from Data (Summarized Data Reports). In determining whether to compile such a report, CHIA will consider the public interest served, the availability of its resources, the complexity of the request, and privacy concerns, i.e., that there is no more than a minimal risk to individual privacy in the public release of the report.

(2) Summarized Data Reports will contain only aggregate data (data summaries) and De-identified Data. Examples of Summarized Data Reports include: counts; totals; rates per thousand; index values; and other standardized metrics. Summarized Data Reports will be subject to CHIA's cell suppression policy and accordingly no cell (e.g., admittances, discharges, patients, services, etc.) less than 11 will be displayed, nor will percentages or other mathematical formulas allowing calculation of a cell less than 11.

(3) The Executive Director or his or her designee will approve or deny such requests. Such approval/denial is final and not subject to further review or appeal.
