  1. 1. RFID in South African Community Health Centers<br />Lindsay Janes<br />Stella Cho<br />Byron Cheng<br />Jason Kim<br />
  2. 2. Overview<br />Many sources of inefficiencies in management of clinics<br />Increase in spreading of disease<br />Create bottlenecks<br />Registering<br />Finding folders<br />Receiving treatment<br />Getting medications<br />
  3. 3. Objective<br />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.<br />
  4. 4. The Status Quo<br />Typical progression throughout CHC: Blueprint of typical CHC: <br />
  5. 5. Step 1: The Entrance and Registration<br />
  6. 6. Alternatives<br />Current situation<br />Requirements <br />Reduce bottleneck<br />Decrease spread of disease<br />Specifications <br />1.6 patients/minute plus companions<br />All patients with TB and RFID tags sent to TB area<br />
  7. 7. Alternatives<br />Possible alternatives<br />Patient with an RFID tag<br />TB patient<br />Not TB patient<br />Patient without an RFID tag<br />TB patient<br />Not a TB patient<br />

  23. 23. Locked doors (barrier)
  24. 24. Decrease in buffer
  25. 25. Warning system</li></li></ul><li>Finding the Folders<br />Currently: Shelves and files sorted by number<br />Find patient number<br />Go to bookshelf where file should be<br />Sift through folders to find file<br />May or may not be in order<br />Time is wasted finding the right bookshelf, section, and the file<br />
  26. 26. Specifications<br />Requirement<br />Find folders more quickly<br />Match up with rate of patients seeing practitioners<br />Specifications<br />Be able to accommodate 4 registration booths<br />Capable of handling 20 patients per hr per practitioner<br />
  27. 27. Alternative 1: LED on Shelves<br />Individual folders have RFID tag<br />LEDs are mounted on every shelf<br />Each shelf has RFID reader that is wired to LEDs and barcode scanners at window<br />
  28. 28. Alternative 1: LED on Shelves<br />Window worker scans patient barcode and name goes in queue<br />System takes names from queue<br />Readers find detect the file and activate corresponding LED<br />Worker goes to shelf and finds the folder manually<br />
  29. 29. Alternative 1: LED on Shelves<br />
  30. 30. Alternative 2: Handheld Reader<br />Each worker assigned an RFID reader<br />Will be programmed to look for particular tag/folder<br />Will beep or blink when brought near the proper tag.<br />
  31. 31. Alternative 2: Handheld Reader<br />
  32. 32. Treatment Area to Pharmacy<br />
  33. 33. Treatment Area to Pharmacy<br />Requirement: To decrease patient waiting time in the pharmacy<br />Specification: A patient should wait no more than 15min to receive medication<br />Alternative 1: RFID automatically registers patient at pharmacy<br />Alternative 2: RFID automatically adds to patients to a wait list when entering the pharmacy waiting area.<br />
  34. 34. Summary<br />Specifications- System must:<br />Be able to accommodate 4 registration booths<br />Be capable of handling 20 patients per hr per practitioner<br />Process entering patients at 1.6 patients/minute<br />Notify patient of their status up to 300 patients at a time<br />Allow a 5 ft buffer space between TB and non-TB patients<br />Ensure that wait time to receive medication does not exceed 15 min<br />
