Haley SM, Ni P, Coster WJ, Black-Schaffer R, Siebens H, Tao W. Agreement in functional assessment: graphic approaches to displaying respondent effects. Am J Phys Med Rehabil. 2006; 85(9):747-55. The objective of this study was to examine the agreement between respondents of summary scores from items representing three functional content areas (physical and mobility, personal care and instrumental, applied cognition) within the Activity Measure for Post-Acute Care (AM-PAC). We compare proxy vs. patient report in both hospital and community settings as represented by intraclass correlation coefficients and two graphic approaches.

J Clin Epidemiol. 2006; 59: 1174-1182. Measuring physical functioning (PF) within and across post-acute settings is critical for monitoring outcomes of rehabilitation; however, most current instruments lack sufficient breadth and feasibility for widespread use. Computer adaptive testing (CAT), in which item selection is tailored to the individual patient, holds promise for reducing response burden, yet maintaining measurement precision. We calibrated a PF item bank via item response theory (IRT), administered items with a post hoc CAT design, and determined whether CAT would improve accuracy and precision of score estimates over random item selection.

Frequency and impact of active clinical issues and new impairments on hospital discharge in patients with hip fracture. Arch Intern Med. 2003; 163(1):108-13. Hip fracture is associated with significant mortality and disability. Patients who are discharged from the hospital with active clinical problems may have worse outcomes than those patients without active clinical problems. The objective of this study was to assess the frequency and impact of clinical problems at discharge on clinical and functional hip fracture outcomes.
Jette A, Haley S, Ni P: A Comparison of Functional Status Tools used in Post-Acute Care. Health Care Fin Review. 2003; 24(3). There is a growing health policy mandate for comprehensive monitoring of functional outcomes across post-acute care (PAC) settings. This article presents an empirical comparison of four functional outcome instruments used in PAC with respect to their content, breadth of coverage, and measurement precision. Results illustrate limitations in the range of content, breadth of coverage, and measurement precision in each outcome instrument. None appears well equipped to meet the challenge of monitoring quality and functional outcomes across settings where PAC is provided. Limitations in existing assessment methodology has stimulated the development of more comprehensive outcome assessment systems specifically for monitoring the quality of services provided to PAC patients.
