Apples and Oranges: Four Definitions of Multiple Chronic Conditions and their Relationship to 30-Day Hospital Readmission.

ABSTRACT:

Objectives

To determine the extent of agreement between four commonly used definitions of multiple chronic conditions (MCCs) and compare each definition's ability to predict 30-day hospital readmissions.

Design

Retrospective cohort study.

Setting

National Medicare claims data.

Participants

Random sample of Medicare beneficiaries discharged from the hospital from 2005 to 2009 (n = 710,609).

Measurements

Baseline chronic conditions were determined for each participant using four definitions of MCC. The primary outcome was all-cause 30-day hospital readmission. Agreement between MCC definitions was measured, and sensitivities and specificities for each definition's ability to identify patients experiencing a future readmission were calculated.
