Association of Patient-Centered Outcomes With Patient-Reported and ICD-9-Based Morbidity Measures
Elizabeth A. Bayliss , and colleagues
Background Evaluating patient-centered care for complex patients requires the ability to approriately measure morbidity (illness) for a variety of clinical outcomes. This study compares the contributions of self-reported morbidity and morbidity measured using administrative diagnosis data for both patient-reported outcomes and utilization outcomes.
What This Study Found A comprehensive assessment of a patient�s morbidity requires both subjective and objective measurement of diseases and disease burden, as well as an assessment of emotional symptoms. Comparing two different approaches to gauging morbidity - (1) objective measurement using ICD-9 diagnosis codes and (2) subjective measurement using patient-reported disease burden and emotional symptoms - researchers conclude both are needed. In data on 961 older adults with three or more medical conditions, morbidity measured by diagnosis code is more strongly associated with higher utilization, whereas self-reported disease burden and emotional symptoms are more strongly associated with patient-reported outcomes.
Implications
- Accurate measurement strategies to account for morbidity burden will become increasingly important in developing new methods for evaluating patient-centered care delivery for complex patients.
