Medical Appointments System
More than patients are registered with a local health centre. The centre employs a number of general practitioners ie doctors and a few receptionists. Patients are officially registered with one doctor but can arrange appointments with any available one. These appointments may subsequently be cancelled. Some appointments result in one or more prescriptions.
New patients are registered by a receptionist. When a patient is registered heshe provides hisher details such as name, date of birth, address, etc., and receives a unique patient number. To book an appointment a patient should contact a receptionist. The patient provides hisher number or date of birth and the receptionist provides a list of available time slots for appointments. The appointment is booked with the patients doctor or if the patients doctor is not available with any available doctor. The date and time of the booked appointment are given to the patient as a confirmation.
Patients can cancel booked appointments by contacting a receptionist who will cancel appointments on behalf of patients. A patient who attends an appointment should check in first using a special terminal located in the waiting area of the Health Centre. The patient inputs hisher number or date of birth The system checks the details and confirms that the patient has been checked in Doctors record appointment outcomes and details of prescriptions if any during the appointments ie all prescriptions issued by doctors are recorded on the patients record. Patients who leave the area where the Health Centre is located are deregistered by receptionists
