Improvement of Patient Satisfaction and Overall Outcomes Using HealthLoop

The purpose of this study is to assess the usefulness and results of orthopedic patients
having access to a cell phone App called HealthLoop to utilize during the postoperative time
period, compared to patients who have the usual postoperative management. The researchers
want to investigate whether there any differences in outcomes and satisfaction in patients
and providers.

HealthLoop is a mobile-device application (cell phone App) that allows physicians to monitor
for signs and symptoms of potential adverse events, and communicate with patients during the
postoperative recovery process. The platform enables doctors to identify patients at risk of
decline in the follow up period. Patients are engaged through mobile and web-based surveys,
reminders, and information personalized to the patient's specific condition or treatment
plan. Alerts are sent to physicians about patients who are at risk of treatment failures,
complications, or hospital readmissions. Physicians are informed if patients are trending
toward an adverse outcome based on the patient's responses.

Patients who choose to participate in this Research Study will be randomly assigned (like a
flip of a coin) to one of two groups. Group A will receive standard, routine medical care.
Group B will be asked to use the HealthLoop application on their mobile device during the
post-operative period in addition to standard, routine medical care. Patients will not be
able to choose which group they will be in.
