We identified two functionalities existing software could address: o Ability to drill down from summaries to increasing levels of detail. o Ability to slice and dice the data into subgroups corresponding to specific interests. • To use such tools, the EPCs will need staff with informatics skills, and the Agency for Healthcare Research and Quality will need to verify Web strategies for public access. • Alternate formats may improve utility of EPC report data to guideline committees in learning health systems. • The recommended pilot extension could confirm usefulness of prototypes and resources needed. iii This report is based on research conducted by the Pacific Northwest Evidence-based Practice Center (EPC) under contract to the Agency for Healthcare Research and Quality (AHRQ), Rockville, MD (Contract No. 290-2015-00009-I).
