Medical registries are organized systems that collect, store, and manage data about patients with specific health conditions or treatments. They help track patient outcomes, monitor disease trends, and evaluate the effectiveness of medical interventions. This information is crucial for researchers, healthcare providers, and policymakers to improve patient care and public health. These registries can focus on various areas, such as cancer, diabetes, or cardiovascular diseases. By analyzing the data, medical professionals can identify best practices, develop new treatments, and enhance overall healthcare quality. Additionally, registries often support clinical trials and contribute to advancing medical knowledge.
