Researchers in this field often study patient outcomes, adherence to clinical guidelines, patient satisfaction, communication between healthcare providers and patients, and the overall delivery of healthcare services. The goal of quality of care research is to identify best practices and strategies to ensure that patients receive high-quality, evidence-based care.
