What is one example of an occurrence-based screening event?

For the question regarding an occurrence-based screening event, the best answer is the discharge counseling session. This type of session occurs as a specific response to a patient's recent hospitalization or medical treatment. It involves assessing the patient’s understanding of their condition, medication management, and ongoing care needs immediately after discharge. This focused interaction typically aims to ensure a smooth transition from hospital care to home, making it an occurrence-based event centered around a significant healthcare milestone for the patient.

In contrast, a routine health check-up and an annual physical exam are generally scheduled at regular intervals and do not rely on specific medical occurrences. They are preventive measures designed to maintain health rather than respond to a specific incident. The vaccination clinic visit also fits a preventive model focused on immunization, rather than an event triggered by a recent occurrence in the patient's health status. These distinctions highlight why the discharge counseling session is the clear example of an occurrence-based screening event.
