Healthcare quality refers to the degree to which health services for individuals and populations increase the likelihood of desired health outcomes. It encompasses various factors, including the effectiveness, safety, and patient-centeredness of care provided by healthcare professionals and institutions. High-quality healthcare aims to meet patients' needs while minimizing risks and maximizing benefits. Key components of healthcare quality include access to services, timely care, and the use of evidence-based practices. Organizations like the World Health Organization (WHO) and Centers for Medicare & Medicaid Services (CMS) set standards and guidelines to help improve healthcare quality across different settings and populations.
