Article Abstract

One part of treating diabetes involves accurate and regular blood glucose measurement. The author describes redesigning a diabetes care system, including using Quality Function Deployment (QFD) to determine the best monitoring device for purchase.

After assembling, a multidisciplianry team found themselves confounded by the number of issues surrounding the redesign. After consulting with the hospital's quality engineer, they chose QFD as their tool. Since blood monitoring is crucial to diabetes treatment, they chose that as their first project. They created a house of quality delineating the patient's and hospital's requirements for a monitoring device. They then evaluated several monitors against these criteria, using a five-point Likert response scale. After fitting the device information into the house of quality, they analyzed the data using the Kruskal-Wallis Nonparametric Analysis of Variance and the Mann-Whitney U Test.

This approach yielded positive results. Patient satisfaction with the new device increased to 90%. The new device included all the necessary technical characteristics. Several disciplines cooperated to form a functioning team. The team established and continued a quality-oriented relationship with the device vendor. More importantly, the success of this effort inspired additional quality achievements.
