The study demonstrates that perceived usefulness, perceived ease of use, subjective norm, and healthcare knowledge together predict most of the variance in patients' acceptance and self-reported use of the web-based self-management technology.

Objective-This 3-year field experiment engaged 60 nurses and 282 patients in the design and evaluation of an innovative home care nursing model, technology enhanced practice (TEP).Method-Nurses in the TEP conditions augmented usual care with a web-based resource (HeartCareII) that provided patients with self-management information, self-monitoring tools, and messaging services.Results-Patients exposed to TEP demonstrated better quality of life and self-management of chronic heart disease during the first four weeks and were no more likely than patients in usual care to make unplanned visits to a clinician or the hospital. Both groups demonstrated the same long term symptom management and health status achievements.Conclusion-This project provides new evidence that it is possible to purposefully create patient-tailored web resources within a hospital portal; that it is hard for nurses to modify their practice routines even with a highly-tailored web resource, and that the benefits of this intervention are more discernable in the early post-discharge stages of care.
