My primary interest is setting up integrated data repositories that can be used to assess and report quality of care outcomes to condition/procedure specific registries. The goal of this activity is to minimize the effort required for registry reporting by utilizing existing data streams and developing methods for capturing data while improving the delivery of clinical care. Working closely with the medical center Orthopaedic surgery service line administrator we developed an integrated data repository (IDR) where an ontology derives terms used by physicians and patients to describe risk factors, surgical parameters and outcomes from diagnosis and procedure codes routinely generated in hospital and physician claims. We recently used data derived from this IDR to respond to Blue-Cross Blue Shield Center of Excellence surveys for hip and knee replacement and spine surgery. We are currently in the process of overcoming regulatory barriers to replicate this IDR at other medical school campuses.
Working with a mobile health startup, Pipette, we were recently awarded a REAC mobile health research award to pilot a mobile phone application that sends patients 10 questions daily for the 14 days after they receive a hip or knee replacement. These questions will help Orthopaedic surgery residents to assess whether patients are experiencing infectious, thrombotic, pain or gastrointestinal complications, and provide data that will be helpful for assessing the clinical success of the operation.
We have applied the ontology to Medicare, private payer and the national inpatient sample to describe trends in Orthopaedic surgery and have developed algorithms that distinguish planned from unplanned readmissions.
