Problem: The hospital soundscape contains noise that can negatively affect patient well-being and healing. Creating a quiet environment in an inpatient setting is challenging due to numerous barriers. Before the implementation of this quality improvement (QI) project, there was no daytime rest period for patients on the cardiac surgery progressive care unit (CSPCU). Purpose: This QI project aims to reduce daytime noise to improve rest among adult inpatients by implementing a structured daytime quiet time hour with specific noise reduction strategies to create a more therapeutic healing environment. Methods: This 15-week quality improvement project was conducted on a CSPCU in a large urban academic medical center in the Fall of 2024. A daily "Quiet Time" (QT) hour was implemented on the unit after providing in-person education to staff on its importance and implementation measures. Noise reduction strategies included dimming the lights, closing patient doors if appropriate, limiting overhead announcements, and encouragement of low voices near patient rooms and nursing stations, and minimizing non-essential patient interruptions. Noise levels were measured before and during QT using the SW-525B decibel readers. Patients and families were informed about QT verbally by staff and informational flyers in patient rooms. Patients discharged home were surveyed on their QT experience. Results: Among the 154 patients who discharged home, 137 patients participated in the QT survey. Of these respondents, 62% (n=85) perceived experiencing QT hour during their stay and 72.3% (n=99) perceived QT helped promote rest and healing. QT successfully decreased noise levels to approximately 7.9 decibels from the initial baseline of 63 decibels. Conclusion: The implementation of a structured daytime "Quiet Time" hour successfully decreased unit noise and promoted a restful, healing environment for patients.
