The exercises also were a fitting way for Elmhurst’s Sim patients to make the move from campus to their new home, the Elmhurst College Simulation Center at Elmhurst Memorial Hospital. Construction is nearly complete on the Simulation Center, a 4,600-square-foot laboratory and classroom space located in the hospital’s lower level. The result of an innovative collaboration between Elmhurst College and Elmhurst Memorial Healthcare, the Simulation Center is the only such center in the region to have been established through this kind of health care/higher education collaboration. Set to open next month, in time for the start of the new academic year, the facility will give students the opportunity to practice protocols and procedures, and run through the most intense medical scenarios, with no risk to patient health. Staff members at Elmhurst Memorial Hospital—and, potentially, first responders and other outside medical-service providers—also will be able to use the Simulation Center for additional training and professional development.
