When a patient must cancel an appointment, it is appropriate to express regret and immediately schedule another appointment. This approach maintains a professional and empathetic relationship with the patient, ensuring continuity of care. Reprimanding the patient or refusing to re-book another appointment can damage the patient-provider relationship and is not considered professional behavior. Instead, expressing regret acknowledges the inconvenience while rescheduling ensures the patient's medical needs are still met.
