HealthCare System (HCS)

Problem Description

A hospital plans to build a healthcare system, which manages patient information. A hospital has a CEO, doctors, nurses and staff. A patient can make an appointment, change, or cancel the appointment by calling a staff in the hospital. When a patient makes an appointment, she/he tells a doctor name to a staff who checks if the doctor is available from 9 am to 5 pm on a half hourly basis. The appointment is recorded in the system, and it is updated whenever the patient changes or cancels the appointment. Each appointment will be cleared after a patient visits a doctor in the hospital. In case of no-show appointments, the system clears the appointments automatically at 8 pm on a daily basis and charges a penalty $25 to each no-show patient. The hospital does not accept walk-in patients.

When a new patient arrives at the hospital, the staff enters the patient information to the system for check-in, which includes patient name, address, phone number, social security number, and health insurance information. The patients doctor visit request is sent to the health insurance company, which approves or denies the request. If the health insurance company approves the patients doctor visit request, the patient name is added to a list of patients being served by a doctor. If the health insurance company denies the patients doctor visit request, the patient should cancel his/her doctor visit or pay all the cost of doctor visit without the health insurance coverage. If the patient wants to cancel, the staff terminates the registration of a patient. If the patient desires to pay all the cost out of his pocket, the patient name is added to a list of patients being served by each doctor. For a returning patient, the staff updates the patient information and the patients doctor visit request is sent to the health insurance company. The remaining process is the same as a new patients doctor visit depending on the health insurances approval or denial.

The nurse measures a patients weight, height, and blood pressure each time a patient visits a doctor, updating the patient record with the measurements. The nurse also adds the reason of patients visit to the doctor to the patient record. After treating a patient, a doctor updates a patient record with his treatment content and, if any, prescription.

A patient pays for the copay or all the cost of the doctor visit to the staff just when checking out. A patient can pay it by credit/debit/cash. In cases of credit or debit card payment, the payment is validated by the card company, and, if approved, the company sends a reference number to the hospital, which is stored with the patients payment information. A patient receives a receipt for the payment.

The system generates a daily summary report at 9 pm every business day and a monthly report at the end of each month. The report shows the information on doctors performance for each day 2 and each month. The daily report contains each doctor name, the number of patients served by a doctor, and health service income. The monthly report is a summary of daily reports for a month. The daily and monthly reports are stored in the system so that the CEO looks at them any time.
