AViKA Care Navigator Intervention Randomized Control “Proof of Concept” Study

We began recruitment in July 2011 for a prospective cohort study evaluating the impact of motivational interviewing on surgical outcomes.  Our enrollment period has now ended with a final cohort of 309 subjects whom we will continue following through their five-year follow-up.

AViKA Observational Cohort Study

Between August 2009 and June 2011, 116 subjects who had undergone total knee replacement surgery were enrolled in the study.  Since completing enrollment and conducting 3- and 6-month follow-up evaluations of our cohort, data analysis has been performed and results have been presented in the form of abstracts and posters.  In 2012, we presented results at the annual conference for the American Academy of Orthopaedic Surgeons (AAOS) as well as at the Osteoarthritis Research Society International (OARSI) World Congress on Osteoarthritis. In November 2012, Jamie Collins presented results at the annual conference for the American College of Rheumatology (ACR), where she discussed patient self-reported Range of Motion as an outcome measure for total knee replacement. We are now in the process of drafting a peer reviewed manuscripts that will further describe observations and conclusions from this prospective cohort study.

AViKA Focus Group Study

We assembled the following four focus groups in 2009 to evaluate patient experiences and surgical outcomes after total knee replacement: (1) 50-64 year old Females; (2) 65-80 year old Females; (3) 50-64 year old Males; and (4) 65-80 year old Males.

In 2010, we created an extensive report for Health Resources in Action summarizing the results from these focus groups.  In this report, we identified aspects of the care process that potentially lead to confusion, miscommunication, and non-adherence to medications, physical therapy, or activity recommendations.  These findings also helped inform our design of the Care Navigator “Proof of Concept” study described above by providing a basis for care navigation and motivational interviewing as methods that might improve patient outcomes following surgery.
