Personal health record systems (PHR) have great potential to improve both health documentation and patient care. The introduction and adoption of these systems, however, have been relatively slow. In this work, through usability evaluations and clinician interviews, we evaluated the usability of, usefulness of, and the ability to communicate and share information through PHR. We describe the re...

BACKGROUND There has been recent interest in using the discrete choice experiment (DCE) method to derive health state utilities for use in quality-adjusted life year (QALY) calculations, but challenges remain. OBJECTIVES We set out to develop a risk-based DCE approach to derive utility values for health states that allowed 1) utility values to be anchored directly to normal health and death a...

A utility function is an important tool for representing a DM’s preference. We adjoin utility functions to multi-objective optimization problems. In current studies, usually one utility function is used for each objective function. Situations may arise for a goal to have multiple utility functions. Here, we consider a constrained multi-objective problem with each objective having multiple utili...
