Development and Validation of the Summary Elixhauser Comorbidity Score for Use With ICD-10-CM-Coded Data Among Older Adults.

ABSTRACT:

Background

Older adults have many comorbidities contributing to mortality.

Objective

To develop a summary Elixhauser (S-Elixhauser) comorbidity score to predict 30-day, in-hospital, and 1-year mortality in older adults using the 38 comorbidities operationalized by the Agency for Healthcare Research and Quality (AHRQ).

Design

Retrospective cohort study.

Setting

Medicare beneficiaries from 2017 to 2019.

Patients

Persons hospitalized in 2018 (n = 899 844) and 3 disease-specific hospitalized cohorts.

Measurements

Weights were derived for 38 comorbidities to predict 30-day, in-hospital, and 1-year mortality. The S-Elixhauser score was internally validated and calibrated. Individual Elixhauser comorbidity indicators (38 comorbidities), the modifi
