A risk model to identify Legionella among patients admitted with community-acquired pneumonia: A retrospective cohort study.

ABSTRACT:

Background

Guidelines recommend testing hospitalized patients with community-acquired pneumonia (CAP) for Legionella pneumophila only if the infection is severe or risk factors are present. There are no validated models for predicting Legionella.

Objective

To derive and externally validate a model to predict a positive Legionella test.

Design, setting and participants

Diagnostic study of adult inpatients with pneumonia using data from 177 US hospitals in the Premier Healthcare Database (training and hold-out validation sets) and 12 Cleveland Clinic Health System (CCHS) hospitals (external validation set). We used multiple logistic regression to predict positive Legionella tests in the training set, and evaluated performance in both validation sets.
