Algorithms identifying low-acuity emergency department visits: A review and validation study.

ABSTRACT:

Objective

To characterize and validate the landscape of algorithms that use International Classification of Disease (ICD) codes to identify low-acuity emergency department (ED) visits.

Data sources

Publicly available ED data from the National Hospital Ambulatory Medical Care Survey (NHAMCS).

Study design

We systematically searched for studies that specify algorithms consisting of ICD codes that identify preventable or low-acuity ED visits. We classified ED visits in NHAMCS according to these algorithms and compared agreements using the Jaccard index. We then evaluated the performance of each algorithm using positive predictive value (PPV) and sensitivity, with the reference group specified using low-acuity composite (LAC) criteria consisting of both triage and clinica
