The goal of this observational study is to learn about sensory loss in hospital patients with delirium. The main questions it aims to answer are: * Are hearing and vision loss related to increased risk of having delirium? * Do hearing and vision loss contribute to more severe delirium? * Do sensory loss and/or delirium affect patient satisfaction with hospital care? Participants will be asked to: * answer delirium screening questions, * undergo hearing \& vision screenings, and * complete questionnaires about the hospital stay. The second part of this study is a clinical trial. Researchers will compare different hospital units to see if changing communication affects the number of patients with delirium. The main questions it aims to answer are: • Does sharing information about communication and/or providing hearing devices change the number of hospital patients with delirium? Participants in the study will be asked to complete delirium screenings and answer questions about their hearing and communication.
