The potential for workplace violence degrades patient and staff safety. AHRQ is developing a survey item set that will help nursing homes identify and improve factors associated with workplace safety. The Workplace Safety Supplemental Item Set will assess the extent to which nursing homes’ organizational culture supports workplace safety. The new supplemental item set can be administered optionally at the end of the SOPS Nursing Home Survey. AHRQ will build this new measure of workplace safety upon its existing and highly successful SOPS program. Results are available from of a pilot study that tested the application of the supplemental item set in the field.
