These problems are recorded in the Diagnosis table. ( For example, a patient might be admitted following an accident could have sustained a Broken Right Arm, Broken Right Leg and Head Injuries)

* A Diagnosis can only be made following an appointment, and the Date and Time is recorded as the Date and Time of the appointment.
