Current Projects Algorithm

Algorithm to Identify Clinically Significant Arthritis with Functional Limitation

Funding number:

CDC/200-2006-M-6444

Project description

The project goal is to explore using available administrative data to identify patients with clinically significant arthritis and functional limitation in a managed care setting and target them for possible intervention. This group with limitation is of particular interest because they are most likely to be receptive to interventions to improve their situation. Because there may be many patients with mild disease who may be getting by with self-medication and not feel ready or motivated to engage in any further interventions, identifying those who may more readily adopt any interventions because of more severe disease (pain, dysfunction, limitations, inability to engage in valued activities) would help target intervention outreach and make a more useful algorithm to health care systems and HMOs.

This project is a follow-up to a completed case definition validation study done at Fallon Clinic between November 2001 and October 2002. The studied classified 389 patients as having clinically significant arthritis or not and functional limitation. This effort uses the study data to evaluate the performance of newly developed algorithms using data from computerized administrative records at Fallon Clinic to identify patients with clinically significant arthritis and functional limitation.

Project objective

The program objectives is to develop an algorithm to easily and accurately identify patients with clinically significant arthritis and functional limitation in managed care settings using administrative data.
