Question

I ned some clues to solve this question from my CIS course:

Hospital Management System

Overview

As the systems analyst hired by a local hospital, you have been asked to analyze the procedures used in both the Emergency room of the hospital, as well as the general admissions desk at this same facility

Findings

During your analysis, you have found that there are many similarities between the admittance desk and the emergency room admittance functions and data requirements. The only real difference is that emergency medical attention may be needed when a patient is admitted into the emergency room and that if the emergency-room admitted patient has no insurance, different arrangements must be made for the patient to pay for their treatment, or if other financial requirements are needed.

Your Job

As the systems analyst with these findings, you are now responsible to:

1. List all data stores that will keep track of the following data to support the automation of this system:

• Patient personal information

• Patient health condition information

• Physician orders for treatment

• Payment details (how will the hospital be paid)

2. Create a Context Diagram showing how Admittance, Patient Diagnosis and Payment will be processed (high level) by the hospital

3. Create a Data Flow Diagram (DFD 0) that shows the external data stores which will keep track of everything in #1 above, and how this data will get into the processes/functions as described in the FDD.

Answer 1

1. Data Stores

• Patient personal information :- Patient
• Patient health condition information :- Patient Reports (Results from Laboratory)
• Physician orders for treatment :- Hospital (Order signed by Physician)
• Payment details (how will the hospital be paid) :- Patient / Patient Accounts

2. Context Diagram

• Admittance :- Blocks (1) & (2)
• Patient Diagnosis :- Blocks (3) & (4)
• Payment :- Block (5)

3. DFD

Below is the list of Data/Info that is shown flowing in the above DFD.

• (a) Patient Info
• (b) Order for treatment
• (c) Patient Reports
• (d) Patient Data & Tests

Explanation for :-

• `(a)` comes from `Patient`
• Stored in Hospital Database
• Shared with `Patient Accounts` module

FDD is the diagram which defines a module at functional level. It shows/describes all the functions/sub-functions of a given module. For example, the FDD for LABORATORY module will show functions :-

• Take as Input `Patient Data & Tests to be done`
• Generate Patient Reports
• Send Reports to `Patient Reports Module`

The question asks about the data that will be used in FDD; not an actual FDD.
