Measuring functional status changes in various patient subgroups is important in stratifying risk, assessing disease severity, and predicting and defining clinically relevant outcomes.
Data from a multicentered study of 980 primary care patients presenting with nonspecific abdominal complaints were studied to demonstrate the importance of such an assessment procedure.
Patients were prospectively followed for 6 months.
Five diagnostic categories based on illness duration and seriousness were derived from the clinical course of these patients.
The functional status of each patient was determined at baseline, 1 month, and 6 months using the Sickness Impact Profile (SIP).
Intraclass correlation coefficients accounted for two aspects of the reliability of the SIP regarding the measurement of change over time : differences between patients which are stable over time (reproducibility) and different effects of treatment between subsets (responsiveness).
A priori formulated expectations about the degree of health status change in patient subgroups were evaluated with the help of effect-size calculations.
Patient impairment only partially depended on the final diagnosis and was also influenced by the presence of co-morbidity, psycho-social determinants, and other complaints.
The health status change in the patient subgroups agreed with a priori formulated expectations.
Standardized effect-size calculations revealed that the degree of change over time in SIP scores w...
