Patient outcomes research is a field of study that focuses on evaluating the effectiveness of healthcare interventions and systems by measuring the outcomes that matter most to patients. These outcomes may include factors such as survival rates, quality of life, functional status, symptom relief, and patient satisfaction. Researchers in this area aim to assess the impact of different treatments, interventions, and healthcare practices on patient outcomes in order to improve the quality and effectiveness of care delivery. This research helps healthcare providers make evidence-based decisions and recommendations that prioritize patient well-being and health outcomes.
