Summary

Four million people in the US are taking warfarin (Coumadin) anticoagulation medication for a variety of medical conditions that place them at risk for intravascular blood clot formation including hypercoagulable states, deep venous thrombosis, and atrial fibrillation. Frequent adjustments of warfarin dosing is required in patients starting and often throughout the course of the anticoagulation. Such adjustments are based on the INR measured by a blood test that is usually performed weekly or biweekly for the first several months after anticoagulation is started. In most cases, on the day after the blood test, the physician or the physician's nurse contacts the patient by phone to make dosing adjustments. If a new pill size is required, then the physician (or physician surrogate) must also contact the pharmacy with a new prescription.

Warfarin is available in 9 different milligram sizes: 1, 2, 2.5, 3, 4, 5. 6, 7.5, and 10. The warfarin automatic home medication dispenser will provide a one month supply of medication of any unitary dose in the usual range (1 to 15mg dosed once per day.) It will also provide for 0.5 mg increments above 2.5 mg in the same range.

The objective of this project is to create a prototype home medication dispensing device that will supply a one month course of warfarin administration. The prototype will have 4 medication compartments designed to contain the following dose/number of pills combinations (1 mg/31 pills, 2 mg/62 pills, 2.5 mg/32 pills, 5 mg/62 pills) which can be combined to provide unitary doses from 1 to 15 mg per day.

Project Readiness Package

The Project Readiness Page documents customer needs and expectations, project deliverables (including time frame), budget, and personnel / organizations affiliated with the project. It will serve as the primary source of information for students necessary during Phase 0 (Planning) to develop a SD I plan and schedule including specific deliverables and due dates. The Project Readiness Package will also support Faculty evaluation of project suitability in terms of depth, scope, and student / faculty resources by discipline.
