Outcome research in nursing focuses on understanding the results of health care practices and interventions. It aims to evaluate how effective these practices are in improving patient outcomes. This type of research is crucial for ensuring that the care provided is evidence-based and leads to the best possible health results for patients.

For example, if a new wound care protocol is introduced, outcome research would measure whether patients heal faster or have fewer infections compared to the previous method. This helps in determining the effectiveness of the new protocol.
