Analysis of Patients With Bed Bugs in the Emergency Department.

The objective was to evaluate the clinical characteristics, triage information, diagnostic evaluation, and disposition for emergency department patients with and without bed bug infestation. A retrospective case-control study of patients with and without bed bugs was performed from February 1, 2011, through February 1, 2017. Cases (n = 332) and controls (n = 4,952) were matched by age, sex, and emergency department location. Patient characteristics and clinical information were compared between groups. On univariable and multivariable analysis, patients with bed bugs had higher heart rate, lower systolic blood pressure, higher pain scores, and more frequent tobacco use in the past year. They were also more likely to screen positive in triage for an unsafe home; require an abuse consultation; be diagnosed in the emergency department or inpatient setting with malnutrition, marasmus, and/or cachexia; have more emergency department and hospital visits; and have longer hospital encounter lengths of stay (all p ≤ 0.02). On univariable analysis, patients with bed bugs were also more likely than uninfested controls to be single, be Black, come to the emergency department from home, arrive to the emergency department by ambulance, and not be discharged back to their homes from the hospital.
