Characteristics of Bed Bug Infested Patients in the Emergency Department

Area of Science:

• Public Health
• Infectious Disease Epidemiology
• Medical Entomology

Background:

• The common bed bug (Cimex lectularius) is a hematophagous ectoparasite experiencing a global resurgence.
• Bed bug infestations pose a significant public health concern, particularly in shared environments like healthcare facilities.

Purpose of the Study:

• To assess the prevalence of bed bug experiences among emergency department (ED) patients.
• To evaluate patient reporting of infestations and healthcare provider implementation of isolation precautions.
• To identify characteristics of ED patients with bed bug infestations.

Main Methods:

• A survey was conducted among 706 active emergency department patients regarding their experiences with bed bugs.
• Data collected included current infestations, previous exposure, knowledge of others with infestations, reporting to providers, and isolation precaution status.
• Demographic and clinical data were compared between patients with and without bed bug infestations.

Main Results:

• 2% of ED patients reported a current bed bug infestation, while 37% reported previous feeding.
• Only 18% of infested patients reported their condition to healthcare providers, and 21% were placed in isolation precautions.
• Patients with bed bugs were more likely to be older and arrive by ambulance.

Conclusions:

• Bed bug infestations are prevalent among emergency department patients, with many unaware of or not reporting their condition.
• Inadequate reporting and isolation precautions for infested patients pose a risk of transmission to other patients and healthcare providers.
• Public health strategies are needed to address bed bug infestations in healthcare settings and prevent further spread.
