Patient-Reported Outcome-Based Performance Measures for Older Adults with Multiple Chronic Conditions.

As measures of health care quality have become more sophisticated, the goals of patient care have expanded into helping patients optimize their functional status and well-being. Patient-reported outcome (PRO) based performance measures (PMs) can measure how well these aspects of care are being delivered and compare the performance of health care systems and different provider groups. Most PMs focus on technical quality of care or such outcomes as survival. For older adults, especially those over age 80 with multiple chronic conditions (MCC), it might be equally important or even more important to have a good quality of life. Therefore, policymakers and researchers have been particularly interested in designing PMs that reflect these patients' goals. To date, no PRO-based PMs have been formally developed or validated specifically for use in older adults with MCC. RAND analysts tested PMs that were based on two prominent instruments for assessing health-related quality of life: the Veterans RAND 36 Item Health Survey (VR-36) and the Patient-Reported Outcomes Measurement Information System 29-item (PROMIS-29) profile instrument. The PROMIS-29 is in widespread use but has undergone limited validation in a geriatric population with MCC. The study had two main aims: first, to validate the PROMIS-29 in this population, and second, to develop a better understanding of the practical use of PRO-based PMs in a geriatric population. To this end, the analysts assessed PM performance based on serial administration of the VR-36 or PROMIS-29, specifically in the MCC population studied.
