Advisor: G. Manimaran Client: Iowa Health Systems, Des Moines

Problem Statement

Difficult to track patients Knowing location of patients Patient data

A need for Real-time patient information Electronic system Enhance communication between staff

Solution

Design and Implement a Digital System that allows the CCU staff to quickly and efficiently keep track of patients status as well as the CCU status as a whole.

Components in the System Patient Status Display Board Web Client Mobile Client Sever and Database

Functional Requirements

Event Entry and Display Laptop workstations Mobile devices

Track Performance Manage Users Interactions

Database

Non-Functional Requirements

Quick interaction 10 seconds or 7 keystrokes

Easy to learn 1 or 2 uses to familiarize

Privacy/Security Improve overall patient flow Extensible and dynamic

Assumptions/ Limitation

Users will be hospital personal within the CCU unit and associated doctors

The network will be reliable Display board will be viewable by personal

within the CCU only

Market Survey

Current Display within the CCU unit at Methodist West Lacking electronic way to display and record

information about current patients Other departments within Hospital are receiving

electronic systems while the CCU is not Old “System”

Marker and Dry erase board Hand-written notes

Risks and Mitigations

Availability of client, or lack thereof. Increased flexibility with meeting times

Privacy/Security issues Coordinating with HIPPA privacy officer

Scope – Requirements creep Sticking to the project schedule

Shelved software (Not used by intended users) Usability testing

ImplementationDisplay Board & Web

ClientLog-in Page• Controlled

Access

Main Page and Display• CCU Map• Patient Table

• Status• Room number• Doctors• Notes• In Restraints• On Ventilator

Add/Edit Patient

Add Patient• Select Empty

room from map• Click add new

patient button

Edit Patient• Click edit button

at end of patient row

• Select desired room from map• Having limited number of fields for

patients allows for quick and easy system maintenance

CCU Map

Visually shows current status of entire CCU

Color Coated statuses • White: Empty room• Red: Critical (not going

anywhere)• Yellow: Stable• Green: Ready to transferAccess to viewing / adding/ editing patient information by clicking a room from the map

Web Client Testing

Unit Testing Firefox/Chrome/IE

Integration Testing Usability Testing

Client feedback / survey Field Testing

Unsuccessful due to client

Web Client Evaluation

Initial Limitations / Issues Familiarizing self with technology Lining up communication Limited feedback from visit

Client Evaluation Easy to use Quick interactions Easy to see status of CCU

Implementation Mobile Client

Tools Xcode IDE iOS simulator

Learning Experience Database Communication Mobile Interface Design Objective C

Implementation Mobile Client

Offers an alternate way of viewing and updating system

Offers same functionality as Web Client• Mange Users• Logs• Manage Patients

Mobile Client Testing

Tested using Apple’s iPhone Simulator Manual Testing on both simulator and iPod

touch device

Mobile Client Evaluation

Issues Client feedback from visit

Limitations User’s willing to learn and use the application Willingness of client to buy devices

ImplementationSever / Database

Automated Unit Testing Edge case Testing UI testing Usability Testing

Testing Results

By implementing system in iterations we were able to find and fix bugs quicker

Able to fix bugs without creating new ones Stronger, more robust system since system

built in iterations allowing code to be tested multiple times with new functionality

Conclusion / Future Work

Over all the project was a success System follows all requirements Client excited to use system

Integrate System with their legacy system Load patient information from their system into

ours
