Outcomes research seeks to understand the end results of healthcare practices and interventions in order to improve quality of care. It studies the effects of management on individuals and populations. Key aspects measured include mortality, physiological measures, clinical events, patient experiences, and functional status. However, outcomes research requires significant time and funding to conduct rigorous methodology, which can be difficult to sustain over the long term. As healthcare is constantly evolving, outcomes research is an ongoing process to discover solutions to problems.
