Defining medication complexity and its effect on outcomes in community dwelling elders receiving home care.

Complexity of medication regimens in community dwelling elders is examined in relationship to emergent care use, hospitalization and self management of medications in this secondary data analysis of OASIS data and medication data from all 2004 open admissions to 15 home health care agencies. Preliminary findings and the use of innovative techniques are discussed highlighting the predictive potential for medication complexity in other settings, risk stratification, and design implications for both clinical tools and databases.
