Which of the following is an example of clinical data?

An admitting diagnosis is an example of clinical data because it directly relates to patient care and clinical decision-making. Clinical data refers to information that is generated during the course of patient care and treatment, including diagnostic information, treatment details, and clinical observations. The admitting diagnosis provides a foundational understanding of the patient’s condition upon entry into a healthcare facility, making it essential for clinicians in the formulation of a treatment plan.

The other options represent various types of data that, while important in healthcare settings, do not fall under the category of clinical data. The date and time of admission pertain to administrative and operational aspects of patient management rather than the clinical evaluation of the patient's health. Insurance information is primarily financial and administrative, focused on billing and payment processes rather than the clinical aspects of care. The health record number serves as an identifier for the patient's medical records, which is vital for record-keeping and information retrieval but does not convey any clinical content related to the patient's health status.
