Overview Many sources of inefficiencies in management
of clinics• Increase in spreading of disease• Create bottlenecks
Registering Finding folders Receiving treatment Getting medications
Objective
Incorporate RFID technology into patient management in South African Community Health Centers (CHCs) in order to increase
overall efficiency of the clinic and decrease the spread of infectious diseases.
The Status QuoTypical progression throughout CHC: Blueprint of typical CHC:
Step 1: The Entrance and Registration
Alternatives Current situation Requirements
• Reduce bottleneck• Decrease spread of disease
Specifications • 1.6 patients/minute plus companions• All patients with TB and RFID tags sent to TB area
Alternatives Possible alternatives
• Patient with an RFID tag TB patient Not TB patient
• Patient without an RFID tag TB patient Not a TB patient
Waiting-Registration Area Current Situation
No separate waiting area Wandering Tuberculosis
Waiting-Registration Area Requirements
Increase transparency Specifications
Notify status - up to 300 patients at a time Alternatives Using RFID
Electronic wait list Name, wait time Text messaging
Waiting-Registration Area Requirements
Contain infectious diseases Specifications
5 ft buffer space between wait area Alternatives Using RFID
Locked doors (barrier) Decrease in buffer
Warning system
Finding the Folders Currently: Shelves and files sorted by number Find patient number Go to bookshelf where file should be Sift through folders to find file
• May or may not be in order Time is wasted finding the right bookshelf,
section, and the file
Specifications Requirement
• Find folders more quickly• Match up with rate of patients seeing practitioners
Specifications• Be able to accommodate 4 registration booths• Capable of handling 20 patients per hr per
practitioner
Alternative 1: LED on Shelves Individual folders have RFID tag LEDs are mounted on every shelf Each shelf has RFID reader that is wired to
LEDs and barcode scanners at window
Alternative 1: LED on Shelves Window worker scans patient barcode and
name goes in queue System takes names from queue Readers find detect the file and activate
corresponding LED Worker goes to shelf and finds the folder
manually
Alternative 1: LED on Shelves
Alternative 2: Handheld Reader Each worker assigned an RFID reader Will be programmed to look for particular
tag/folder Will beep or blink when brought near the
proper tag.
Alternative 2: Handheld Reader
Treatment Area to Pharmacy
Treatment Area to Pharmacy Requirement: To decrease patient waiting
time in the pharmacy Specification: A patient should wait no more
than 15min to receive medication• Alternative 1: RFID automatically registers patient at
pharmacy• Alternative 2: RFID automatically adds to patients to a
wait list when entering the pharmacy waiting area.
Summary Specifications- System must:
• Be able to accommodate 4 registration booths• Be capable of handling 20 patients per hr per
practitioner• Process entering patients at 1.6 patients/minute• Notify patient of their status up to 300 patients at a
time• Allow a 5 ft buffer space between TB and non-TB
patients• Ensure that wait time to receive medication does not
exceed 15 min
