Health Partner Evaluation at Princeton


This is a prospective, single-center, randomized, comparative, controlled study. Princeton HealthCare System will enroll a total of 296 subjects (18 years or older) who are electing to have total knee or hip replacement surgery. Subjects will be randomized to either the treatment group (Health Partner alongside standard care) or the control group (standard care alone). Health Partner is a combination of an iPhone or iPod Touch Operating System mobile application and a health care provider portal. The primary objective is to compare care plan adherence (pre- and post-surgery) for Health Partner vs. control subjects. Secondary objectives include evaluating all-cause medical resource utilization, communication with health care provider, well-being, fear of surgery, confidence in recovery from surgery, sleep, and patient satisfaction for 90 days post-surgery. The total planned study duration is approximately 1 year and 7 months.
