Variables and Outcomes in Patient Room Design: A Study of Design Hypotheses
Objective: Research was conducted to evaluate the correlation between design hypotheses and performance outcomes in single-occupancy patient rooms. Background: Health environments host complex interactions between patients and clinicians, and patient rooms offer a unique lens to understanding the impact of design on interactions and outcomes. This places importance on articulating, measuring, and assessing design hypotheses. This study of documented strategies and measured outcomes in patient room design investigates the relationship between design variables and clinical interactions. Methods: Design hypotheses were identified for the strategic approach to four key elements of patient room design: the room configuration, charting location, personal protective equipment (PPE) supply, and mobile supply cart. Researchers collected observational data from existing and newly constructed patient rooms in order to evaluate performance outcomes related to design hypotheses. Results: Observation data supported hypotheses behind three of the four design components and revealed greater insight into how design variables impacted interactions in patient rooms. Conclusions: The study identified a distinction between “fixed” design elements, such as the configuration of the patient room, and “dynamic” elements such as the design of the mobile cart. This was more prevalent in evaluating the use of supply carts and PPE cabinets, which may be more influenced by training, while the room configuration and charting location require little training to benefit both clinicians and patients. This study points to the value of research that evaluates correlations between design hypotheses and outcomes in healthcare design.
