Which of the following is an example of a component of CDS?

Clinical Decision Support (CDS) systems are designed to enhance healthcare delivery by providing clinicians with clinically relevant knowledge and patient-specific information to assist in making decisions about patient care. Diagnostic support is a critical component of CDS as it aids healthcare professionals by suggesting potential diagnoses based on the patient's symptoms, medical history, and other relevant data. This type of support helps ensure more accurate and efficient clinical decisions, ultimately improving patient outcomes and reducing the likelihood of errors.

Other components listed, such as medical billing software, physical examination tools, and patient scheduling software, serve different functions within the healthcare system. They may support administrative tasks and patient management but do not directly assist in the clinical decision-making process like diagnostic support does.
