Patient-centered registries offer efficient, effective infrastructure for real world evidence generation to guide clinical practice and device assessment.

FORCE-TJR merges patient-generated data with administrative and clinical data to serve clinical and policy evaluations of devices, surgical practice, and timing and use of orthopedic interventions. For example, we have established the infrastructure for collection and review of clinical records and radiologic studies. In addition, the University of Massachusetts Medical School has new facilities to support gait evaluations and collection and storage of biological samples. Ancillary research is ongoing using each of these resources with patients from select FORCE-TJR sites. Together with patient-reported data, these refined clinical information allow FORCE to support randomized clinical trials, prospective device surveillance studies, and translational research.

Our methods assure consistent measurement of key risk factors before, during, and after treatment to support precision medicine and outcome prediction analyses. FORCE-TJR practices engage patients to assure patient values and outcome assessments are included in analyses and to monitor long-term patient outcomes- beyond data captured in any one healthcare system electronic record or payer database.

FORCE-TJR illustrates Learning Healthcare System Principles

FORCE-TJR was highlighted in a discussion paper ‘Clinician Engagement for Continuous Learning’ published by the National Academy of Medicine, as an example of learning healthcare system. At the conclusion of the original cohort in late 2015, FORCE-TJR and its methods (patient enrollment, reporting, and benchmarking system) opened to all US surgeons through enrollment into QI-FORCE. QI-FORCE supports the ongoing shared data for comparative effectiveness and outcomes research while simultaneously providing point of care information, periodic risk-adjusted, comparative outcome reports, and data to support success in the bundled payment environment. Interested hospitals and physicians, including those participating in the new CMS value-based payment models for TJR, are joining. Pre-operative and post-surgical data collection follows the same timeline and metrics of the initial FORCE-TJR cohort. The risk-adjusted outcome data returned to member sites foster quality improvement activities and allow clinical systems to anticipate outcomes to be reported on CMS public sites (e.g., and in value payment programs. In addition, participation meets maintenance of certification requirements of the American Board of Orthopedic Surgeons. Thus, the FORCE-TJR system is one model for implementing the learning healthcare system.

Framework for Patient-reported data capture; Lessons learned

As the value of measuring and collecting patient reported outcomes is consistently recognized, lessons learned from the FORCE-TJR experience, in particular, served to guide a much needed framework to PRO implementation. The proposed PRO implementation model stemmed from a recent workshop including experts from various background, who analyzed how PROs are valuable to different stakeholders (i.e., clinicians, hospital leaders, insurers, and researchers), as well as optimal timing, measures selection, costs, and other considerations.

Defining an international outcome measure set for Total Joint Replacement

FORCE-TJR leaders chaired (Franklin) and participated (Ayers) in the international consensus panel to define an outcome measure set to support international outcomes research. Of note, the FORCE-TJR measure set parallels the final recommendation assuring that FORCE-TJR data will contribute to future international comparison efforts.

Development and implementation of web reporting system to return data to surgeons

FORCE-TJR provides quarterly reports to enrolled surgeons that include summaries of their patients outcomes and national benchmarks to improve care and decision-making. Lessons learned from the development and implementation of this web reporting are depicted in a couple of publications.

Patient-reported adverse events improve postdischarge surveillance

Reinforcing the value of patient-reported outcomes, including adverse events within the FORCE-TJR cohort, we reported that almost one-third of patients sought care from facilities others than the hospital where the TJR occurred. We were able to confirm the validity of the self-reports, which improved postdischarge surveillance and decreased missing data.
