Characteristics of Bed Bug Infested Patients in the Emergency Department

Abstract EN

Cimex lectularius L., the common bed bug, is a hematophagous human ectoparasite that has undergone a global resurgence in the past two decades.

We surveyed 706 active emergency department (ED) patients about their experiences with bed bugs.

We found that 2% of ED patients reported having a current bed bug infestation, significantly more than the historical number of ED patients upon which we find bed bug; 37% of ED patients report previously having been fed on by a bed bug; 15% currently know someone with an active infestation; and 59% know someone that has had an infestation within ≤ 5 years.

Only 18% of bed bug infested patients reported their infestation to emergency medicine providers and only 21% were put in isolation precautions.

We found that 25% of patients with bed bugs worried about receiving worse healthcare because of their infestation.

Persons with bed bugs were more likely compared to those without bed bugs to be older (52 vs.

41 years) and arrive by ambulance (57% vs.

14%) (p < 0.05), but not reporting insomnia (50% vs.

49%) (p = 1.0).

Bed bug infested patients can be common in the ED.

Most bed bug infested patients are older, arrive to the ED by ambulance, do not report their infestation to healthcare providers, and are not adequately placed into isolation precautions, potentially putting other patients and providers at risk for acquiring the infestation.
