Risk factors for Lyme disease stage and manifestation using electronic health records.

ABSTRACT:

Background

Little is known about risk factors for early (e.g., erythema migrans) and disseminated Lyme disease manifestations, such as arthritis, neurological complications, and carditis. No study has used both diagnoses and free text to classify Lyme disease by disease stage and manifestation.

Methods

We identified Lyme disease cases in 2012-2016 in the electronic health record (EHR) of a large, integrated health system in Pennsylvania. We developed a rule-based text-matching algorithm using regular expressions to extract clinical data from free text.

Among cases classified by stage, we evaluated individual, community, and health care variables as predictors of d
