What does the literature tell us about the elements of the organizational culture—or micro culture—in emergency departments that may impact the care provided to the older adult who presents in the emergency department with what is perceived by staff as a non-acute condition or complaint? In the U.S. and Canada, the population 65 years of age or older accounts for between 15% to 20% of all emergency admissions. Older adults stay in the emergency department longer than younger adults, and therefore potentially consume more of one of the limited resources in emergency departments—time. The older adult is also more at risk for adverse effects from admissions to emergency departments, and this can impact length of stay in hospital and levels of functioning at discharge. The aim of this scoping study is to map the presence of the three levels of culture (artifacts, values and beliefs, and assumptions) in Schein’s (2010) organizational culture assessment framework in the literature on organizational culture in emergency departments. The methodology used was the Arksey and O’Malley framework for scoping studies. The main finding on the artifact level was that emergency departments are not designed with the older adult in mind. The main findings on the values and beliefs level were that emergency departments are for urgent cases, that older adults do not receive the care and respect they should be given, that there is not enough time in the department, that teams are important, and that emergency nurses feel competent providing emergency nursing but were not focused on good nursing care, particularly not traditional bedside nursing care. The main assumptions underlying these values and beliefs were that older adults did not belong in the emergency department, most visitors to the department were not really critically ill and therefore could wait, and that staff needed to be available for acute cases at all times. A systematic review of a variety of literature on this topic is warranted in order to bring the findings from separate research efforts up to the evidence level of a summary. This review could then support changes to improve care provided to older adults in the emergency department through evidence.
