Patient Record and Scheduling System (PRS System)
A patient record and scheduling system in a doctor’s office is used by the
receptionists, nurses, and doctors. The receptionists use the system when a
patient calls for an appointment. The receptionist will use the system to
schedule the appointment and enters new patient information when first-time
patients visit the doctor. The doctor will first view the patient’s information
before prescribing medication or multiple medications. The doctor may enter
treatment information, but most frequently they let the nurses enter this
information. The nurses use the system to keep track of the results of each
visit including diagnosis and medications. The nurses can also access the
information to print out a history of patient visits. For each visit, free form text
fields are used captures information on diagnosis and treatment. Usually a
patient belongs to or is part of a family, and the head of the family is
responsible, as he provides the primary medical coverage. Patients are
classified are either patients with medical cover or out-patients. Out-patients
must pay with cash after the visit. Information about doctors is maintained
since a family has a primary care physician, but different doctors may be the
ones seeing the patient during the visit.

Q6 (cont.)
Patient history usually reflects the visit to the doctor, and the
doctor’s diagnoses and medication prescribed. The problem
is where to store this information: do you store it with the
visit, to with the doctor? To solve this, we suggest you create
an association class named Patient-History.
(Type of association?)
 Patients can be classified as follows: A patient is either an
out-patient or an insured patient
(Type of association?)
