A) Optimal Medication Monitor(s) and Method of Retrieving Adherence Record.
B) Other Dose Removal Monitors.
While not a medication monitor, we thought it would best to mention the development of a DOT system based on having the patient come to a treatment station that utilizes a biometric fingerprinting terminal to provide transparent and tamper proof records of which doses of TB medication are administered to a patient under supervision of a health worker. The system includes daily uploads to the clinic in charge of the patient by mobile phones with a laptop computer, GMS modem, and SMS server.
It is being evaluated in high-density slum areas in Dehli, India. Although not without problems the initial evaluation looks promising. (1)
The cost of the system would probably make it impractical in areas with less population density, especially rural areas.
