This rule was revised, and the final version published in December 2015. Revisions were conducted in partnership with representatives from the hospitals and ambulatory care centers. The revisions updated the list of reported events to be consistent with National Standards, to reduce duplication, and to improve transparency and outcome improvement. Comments were captured through the monthly users group which is comprised of hospital quality managers and include expanding to skilled nursing facilities, expanding concept of root cause analysis to causal analysis to give more flexibility to reporting facilities, adding a harm scale, and instituting annual reporting requirements. The last revision conducted in 2015 expanded reporting to be consistent with the National Quality Forum list of serious reportable events and to include Skilled Nursing Facilities.
