Outcome research focuses on evaluating the effects of nursing care and interventions on patients, groups, or organizations. It is used to establish evidence-based practice. Outcomes can be measured in the short, intermediate, and long term. Short term outcomes are achieved quickly, like increasing knowledge, while long term outcomes reflect behavioral changes. Measuring outcomes helps improve care but can be time consuming as conclusions change constantly. Various organizations fund outcome research to inform healthcare decisions and make care safer, higher quality, and more accessible. The Collaborative Alliance for Nursing Outcomes collects nursing measurements to help organizations evaluate outcomes.
