Clearly defined and tracked outcome measures are necessary for evaluation of health services. In the hospital setting, clinical deterioration as a nurse-sensitive outcome (NSO) measure is widely recognized and clearly defined, yet there is a lack of clarity around NSO in out-of-hospital settings. This review identified 34 studies and reviews of clinical deterioration in community settings, such as ambulatory or home care. Contributing factors were similar to those identified in hospitals, including workload, staff mix, and education.
