Archived Measure Specifications

Imaging Efficiency Measures

The Outpatient Imaging Efficiency (OIE) measures’ technical specifications are subject to periodic review that can result in changes reflecting advancements in clinical decision-making and technology. Specification changes may occur in a measure's numerator, denominator, and/or exclusions. Specifications are updated in response to Technical Expert Panel (convened annually) feedback and other stakeholder input, as well as from results found in annual literature reviews.

This measure specification archive is intended to support analysis and interpretation of Hospital Compare public reporting results across years. This page provides the measure specifications for each measure in public reporting from 2011 through 2017. If a measure’s specifications do not appear in the archives for a certain year, its specifications are unchanged. For example, archived specifications with a date of 2013 reflect the specifications used to calculate measure results in 2013 and 2014.

Consult this archive to obtain accurate specifications for the calendar year of measure values in which you have interest.
