Patient outcome research focuses on assessing the impact of healthcare interventions on patients' health and well-being. This area of research aims to evaluate the effectiveness and quality of healthcare services by measuring various outcomes, such as mortality rates, disease progression, functional status, and quality of life. Researchers in this field may use a variety of methodologies, including clinical trials, observational studies, and patient surveys, to analyze and interpret the data gathered from patients receiving different treatments or interventions. The ultimate goal of patient outcome research is to improve healthcare delivery and patient care by identifying the most effective and beneficial interventions for patients.
