Clinical information systems are digital platforms used in healthcare to manage patient data and support clinical decision-making. These systems help healthcare providers access and share important information, such as medical histories, lab results, and treatment plans, improving the quality of care. By integrating various functions like electronic health records (EHRs) and patient management, clinical information systems streamline workflows and enhance communication among healthcare professionals. This leads to more efficient patient care and better outcomes, as providers can make informed decisions based on accurate and up-to-date information.
