Assessing current capabilities and barriers to performing routine laboratory tests on patients with suspected high consequence infectious disease at frontline acute care hospitals.

Abstract

Introduction: Patients with a suspected high-consequence infectious disease (HCID), such as Ebola virus disease, may require routine laboratory testing to guide management. We assessed the capabilities of frontline hospitals and the barriers they face performing laboratory testing for patients with a suspected HCID.

Methods: A one-time confidential REDCap survey querying capabilities to safely perform laboratory tests that the Centers for Disease Control and Prevention considers critical for patients with a suspected HCID was sent to 95 institutions in Baltimore, MD, Boston, MA, New York City, NY, and Washington, DC, from January to May 2025.

Results: Fifty (53%) institutions responded, mostly teaching hospitals (96%), with 24% reporting prior experience evaluating a patient with suspected Ebola virus disease. While many hospitals could perform on-site blood gas (70%), hemoglobin/hematocrit (68%), and lactate (68%) tests on a suspected HCID patient, fewer could safely perform a chemistry panel (64%), a urinalysis (60%), a complete blood count with differential (56%), and a malaria rapid diagnostic test (RDT) (48%) on a suspected HCID patient. The five tests respondents most often considered extremely or very important were hemoglobin/hematocrit (91%), chemistry panel (90%), CBC with differential and platelet count (89%), malaria RDT (88%), and blood gas (88%). Reported barriers to performing routine laboratory testing included issues related to patient and staff safety, infection control, lack of appropriate space, and funding.

Conclusions: Our survey identified several barriers to implementing safe laboratory testing. The inability to conduct these laboratory tests may result in delays in care when an HCID is suspected.
