Multidisciplinary Acute Care Research Organization


The Multidisciplinary Acute Care Research Organization (MACRO) provides support services to principal investigators seeking to maximize the productivity and efficiency of acute care research, from the pre-hospital setting to the ICU and inpatient wards. MACRO offers a wide range of services, including 24/7 screening and enrollment into clinical trials and assistance in the conduct of prospective, observational, patient-oriented acute care research. Our mission is to advance medicine and science, through excellence in execution of screening and enrollment day-and-night, local and national coordination, and stakeholder education of multidisciplinary clinical research. Our vision is to be the national role model for academic multidisciplinary clinical research organizations.
