Background. Nurses have an opportunity to improve services and enhance patient care. The purpose of this research is to highlight the missing voice of the frontline nurses and their experience in implementing a quality improvement (QI) initiative called comfort rounds. Comfort rounds are an Elder-Friendly QI initiative that involves purposive rounding conducted at regular intervals on patient care units. Objectives. 1) To understand the experiences of nurses that participated in comfort rounds. 2) To describe the facilitators and barriers to the participation of nurses in the introduction of comfort rounds. Methods. A single case study design, using multiple data sources, was used to explore and collect detailed descriptions of comfort round implementation on an acute medical unit. Findings. Frontline staff can help identify barriers and facilitators for comfort rounds. Engaging frontline nurses throughout the entire QI initiative process (i.e. from planning stages to sustainability) is essential for implementing practice change.
