Clinical Quality, Patient Safety and Outcomes

Every healthcare company claims to improve quality. Few can show it. Quality is hard to measure, slow to change, confounded by who the patients are, and paid for only indirectly. Yet quality measures now move real money: Medicare Advantage star ratings shift billions of dollars of bonus payments, hospital penalty programmes adjust Medicare payments by up to several percent, and outcome claims decide whether employers, payers and health systems buy digital-health and value-based-care products. This section explains how quality is defined and measured (HEDIS, CAHPS, star ratings, safety indicators), the patient-safety movement since To Err Is Human, how evidence is ranked (RCTs, observational studies, real-world evidence), and, most practically, how to judge an outcomes claim.
