Evaluating the Effectiveness of Home Health as a Disease Management Strategy.

Home health (HH) is considered by many to be complementary to existing disease management (DM) programs, or even suitable as a stand-alone DM intervention. The advantage is thought to be with the face-to-face interaction, in contrast to the standard DM telephonic interview. However, much of the literature appears to indicate that telecommunication is as successful as face-to-face contact (typically referred to as "usual care") for administering health surveys, providing counseling, changing health behaviors, and monitoring physiologic functioning. Given the desire to expand into the area of DM, HH agencies will need to identify and demonstrate areas in which they have a clinical and competitive edge over traditional DM models. This article describes and provides examples of three research designs that may assist the HH industry in evaluating their effectiveness in delivering DM services: the randomized controlled trial, the regression-discontinuity design, and case-control matching on the propensity score.
