How long since the patient was last seen (dismissed from an appointment).

Logic: Patients without any visit history receive 80 points. The longer the absence, the higher the risk.

Number of no-show appointments in the past 12 months.

Logic: Each no-show adds 10 points. Patients who miss appointments repeatedly are at compounding risk of dropping out entirely.

Whether the patient has any scheduled future appointment.

Logic: If a future appointment exists, the patient is excluded from the alert board entirely (score = 0). A scheduled appointment means the patient is still engaged.
