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 doctor’s

to the doctor, and the 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?) 15 Systems Analysis and Design in a Changing World, 6th Edition
