A medical registry is a systematic collection of data on patients who have a specific medical condition or who have undergone a particular procedure or treatment. These registries are often used to track outcomes, monitor trends, and evaluate the effectiveness of treatments or interventions in real-world clinical settings. Medical registries can provide valuable information for healthcare providers, researchers, policymakers, and patients to help improve the quality of care and outcomes for patients with various medical conditions. These registries can be used to identify best practices, monitor safety and effectiveness of treatments, and facilitate research on rare diseases or long-term outcomes.
