Michael Klompas, Shangyuan Ye, Vineeta Vaidya, Aileen Ochoa, Meghan A Baker, Karen Hopcia, Dean Hashimoto, Rui Wang, Chanu Rhee,

We compared healthcare worker SARS-CoV-2 infection rates between March-August 2020 in two similar hospitals with high versus low airborne infection isolation room utilization rates but otherwise identical infection control policies. We found no difference in healthcare worker infection rates between the two hospitals nor between patient-facing vs non-patient-facing providers. ... Read more >>

Wenjing Ji, Caroline McKenna, Aileen Ochoa, Haiyan Ramirez Batlle, Jessica Young, Zilu Zhang, Chanu Rhee, Roger Clark, Erica S Shenoy, David Hooper, Michael Klompas, ,

Importance:Hospital-acquired pneumonia is the most common health care-associated infection in the United States. Most cases occur in nonventilated patients, but many hospitals track hospital-acquired pneumonia only in ventilated patients because of the complexity and subjectivity of conducting surveillance for large numbers of nonventilated patients. Objective:To propose and assess potentially objective, ... Read more >>
