Use of a matrix to select home-based technology for HeartCare II.

Access to consumer health informatics innovations requires availability of certain technical resources. We discuss the use of a decision analysis matrix in selecting technology for home use by participants in the HeartCare II project, a web-based resource for patients managing congestive heart failure. The matrix provided the structure for collecting, displaying, and comparing data about the requisite criteria for the technology. Its utility for a variety of decision problems with dissimilar data elements is posited.
