Acuity-Based Staffing


All Oregon Community-Based Care facilities must adopt an Acuity-Based Staffing Tool (ABST) to determine the appropriate number of direct-care staff necessary to provide care services to residents based on individual resident acuity.

Assisted living and residential care facilities may choose to use the ABST provided by the Oregon Department of Human Services or another ABST.
