Some Health Care Workers Are Wary Of Getting COVID-19 Vaccines
Some health care workers have voiced concerns about safety and potential side effects from COVID-19 vaccines. They want to see clear data on safety and efficacy before they sign on to get a new vaccine, Mahon says. "It's a minority of people that are saying absolutely no way [to getting a COVID-19 vaccine]," says Dr. Marci Drees, hospital epidemiologist for ChristianaCare and a liaison to the CDC's federal vaccine advisory committee. "I think the majority of people really just want to know more."

Antibiotic prescribing by telephone in primary carePharmacoepidemiology & Drug Safety
Edward Ewen, Vincent J. Willey, Paul Kolm, William F. McGhan, Marci Drees
Little is known about the contribution of telephone‐based prescribing on overall antibiotic utilization. The objective of this study was to determine the extent and characteristics of telephone‐based antibiotic prescribing in teaching and non‐teaching primary care practices.
The Evolving Landscape of Healthcare-Associated Infections: Recent Advances in Prevention and a Road Map for ResearchInfection Control & Hospital Epidemiology
Nasia Safdar, Marci Drees, et al
This white paper identifies knowledge gaps and new challenges in healthcare epidemiology research, assesses the progress made toward addressing research priorities, provides the Society for Healthcare Epidemiology of America (SHEA) Research Committee's recommendations for high-priority research topics, and proposes a road map for making progress toward these goals.
Universal Glove and Gown Use and Acquisition of Antibiotic-Resistant Bacteria in the ICUJAMA
Harris, A.D., Pineles, L., Belton, B., Johnson, J.K., Shardell, M., Loeb, M., Newhouse, R., Dembry, L., Braun, B., Perencevich, E.N. and Hall, K.K.
Antibiotic-resistant bacteria are associated with increased patient morbidity and mortality. It is unknown whether wearing gloves and gowns for all patient contact in the intensive care unit (ICU) decreases acquisition of antibiotic-resistant bacteria.
Carrots and sticks: achieving high healthcare personnel influenza vaccination rates without a mandateNational Library of Medicine
Marci Drees, Kathleen Wroten, Mary Smedley, Tabe Mase, J Sanford Schwartz
Objective: Achieving high healthcare personnel (HCP) influenza vaccination rates has typically required mandating vaccination, which is often challenging to implement. Our objective was to achieve >90% employee influenza vaccination without a mandate.
Research Methods in Healthcare Epidemiology and Antimicrobial Stewardship: Use of Administrative and Surveillance DatabasesNational Library of Medicine
Marci Drees, Jeffrey S Gerber, Daniel J Morgan, Grace M Lee
Administrative and surveillance data are used frequently in healthcare epidemiology and antimicrobial stewardship (HE&AS) research because of their wide availability and efficiency. However, data quality issues exist, requiring careful consideration and potential validation of data. This methods paper presents key considerations for using administrative and surveillance data in HE&AS, including types of data available and potential use, data limitations, and the importance of validation. After discussing these issues, we review examples of HE&AS research using administrative data with a focus on scenarios when their use may be advantageous. A checklist is provided to help aid study development in HE&AS using administrative data. Infect Control Hosp Epidemiol 2016;1-10.
