Relationship Between Sleep-Wake Quality and Nocturnal Medical Orders

The goal of this randomized controlled clinical trial is to evaluate if the implementation of an adjusted nighttime medical order protocol can improve sleep quality and stabilize physiologic parameters in hospitalized adult patients admitted to general wards. The main questions it aims to answer are: Does reducing non-urgent nocturnal medical interruptions increase total sleep time and REM duration? Does improving sleep continuity enhance subjective sleep quality and physiologic stability (heart rate, blood pressure)? Researchers will compare the intervention group (patients under an adjusted nighttime order protocol) with the control group (standard hospital care) to determine whether reorganizing nighttime medical routines improves objective and perceived sleep outcomes. Participants will: Wear a Fitbit Sense® device to continuously monitor objective sleep parameters across three hospital nights. Complete the Pittsburgh Sleep Quality Index (PSQI) at admission and discharge to assess subjective sleep quality. Undergo standard nighttime vital sign evaluations according to their assigned study protocol.
