Inflammation and Medical Provider Attitudes, Cognition, and Treatment Decisions Study
Sponsor: University of Arkansas, Fayetteville
Summary
This is a randomized, double-blind clinical trial involving emergency medicine and internal medicine healthcare providers as participants. The intervention involves the administration of the seasonal influenza vaccine or a saline placebo; this protocol is used in psychoneuro-immunology to simulate a state of mild illness. The primary aim is to examine whether acute inflammation induced by receiving the vaccine affects decision-making on standardized psychological reaction time tasks and questionnaires. Participants attend two laboratory sessions on consecutive days, receive either a seasonal influenza vaccine or a saline placebo at the first session, provide blood samples to measure inflammatory cytokines, and complete a series of standardized assessments of medical decision-making and social attitudes. Participants who received the placebo during the first session will receive the vaccine during the second session. Overall, the study is designed to examine how adverse provider conditions particularly acute inflammation, burnout, and concerns about one's own health affect provider judgments and healthcare-related decision-making. The primary hypothesis is that providers experiencing greater adverse conditions at the time of research participation would have altered decision-making compared to those experiencing fewer adverse conditions.
