Reorganizing nighttime medical routines significantly improves objective and subjective sleep quality in hospitalized adults
In a randomized controlled trial, an intervention protocol that rescheduled non-essential nocturnal procedures (vital sign checks, medication administration, laboratory sampling) led to longer total sleep time (geometric mean 398 vs. 301 min, p=.015) and longer REM sleep duration (79.2 vs. 58.0 min, p=.010) compared to standard care. Subjective sleep quality also improved, with lower PSQI scores at study completion (4.6 vs. 8.7, p=.040).

Reorganizing nighttime medical routines significantly improves objective and subjective sleep quality in hospitalized adults The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 44/100 (low).
The Claim
Reorganizing nighttime medical routines significantly improves objective and subjective sleep quality in hospitalized adults
This conclusion is most relevant to: Hospitalized adults (mean age 41.2 years, 56.9% female) in general hospital wards in Latin America.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Effect of a nighttime medical order adjustment protocol on objective and subjective sleep quality in hospitalized adults: a randomized controlled trial. (Sleep advances : a journal of the Sleep Research Society, 2026) —
How It Works
The proposed biological pathway:
- ▸Non-essential nighttime medical activities disrupt sleep
- ▸Rescheduling these activities to daytime reduces nighttime interruptions
- ▸Patients experience longer uninterrupted sleep, including REM sleep
- ▸Improved objective and subjective sleep quality
Who Might Benefit
Evidence fit by population:
- ▸Hospitalized adults (mean age 41.2 years, 56.9% female) in general hospital wards in Latin America
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Small sample size (n=51) limits generalizability
- ▸Objective sleep measured with consumer wearable (Fitbit Sense) rather than polysomnography
- ▸Single-center study in Latin America may not generalize to other settings
- ▸Only two intervention nights, short-term effects unknown
Frequently Asked Questions
What was the intervention in this study?▼
The intervention was a nighttime medical order adjustment protocol that rescheduled non-essential nocturnal procedures (routine vital sign checks, medication administration, laboratory sampling) to daytime hours.
How was sleep quality measured?▼
Objective sleep parameters (total sleep time, REM sleep duration, awakenings) were monitored using Fitbit Sense over three nights. Subjective sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) at baseline and study completion.
What were the main results?▼
The intervention group had significantly longer total sleep time (398 vs. 301 min) and REM sleep duration (79.2 vs. 58.0 min) compared to controls. PSQI scores were also lower (4.6 vs. 8.7), indicating better subjective sleep quality.
Who were the participants?▼
The study included 51 hospitalized adults (mean age 41.2 years, 56.9% female) in general hospital wards in Latin America.
