Health Services Research is a field that examines how people access healthcare, the costs of care, and the outcomes of various health interventions. It aims to improve the quality and efficiency of healthcare services by studying factors like patient behavior, healthcare policies, and the organization of health systems. Researchers in this field use various methods, including surveys and data analysis, to gather information. Their findings help policymakers, healthcare providers, and patients make informed decisions, ultimately leading to better health outcomes and more effective use of resources in the healthcare system.
