Using Cross-Classified Multilevel
Models To Estimate The Impact Of Patient-Level Risk Factors And Time-Varying
Hospital Until On Healthcare-Associated Clostridioides Difficile Infection
Thursday November 7, 2024 from 12:00-1:00pm
Virtual Teams Presentation
The use of multilevel modeling in epidemiology allows health researchers to examine how a person’s physical or socially constructed environment may influence their health exposures or disease occurrence. This TechTalk will provide an overview of how multilevel modeling can be used in epidemiologic research in a clinical setting. A traditional example of a multilevel data structure considers how a person’s health may be influenced by their neighborhood or place of residence. In an inpatient setting, we can consider how a patient’s health status may be influenced by their physical environment, such as their room, unit, or hospital. We will walk through an example of this method using data from a case-control study of ChristianaCare patients, evaluating patient-level risk factors for Clostridioides difficile infection, accounting for the patient’s physical environment throughout their hospitalization. Challenges in conducting research in this setting will be discussed and analytic solutions proposed.
