Postoperative sleep disturbance is highly prevalent (89.5%) and is associated with increased opioid consumption and prolonged hospital length of stay.
In a prospective cohort of 143 adult surgical patients, 89.5% experienced poor sleep quality on the first postoperative morning. Poor sleepers had significantly higher 24-hour opioid consumption (r=0.41, P<0.001) and longer median hospital stay (4 days vs 3 days, P=0.018).
This article is automatically generated from the structured evidence profile behind the claim above. Scores reflect the quality and quantity of available research, not clinical advice.
Postoperative sleep disturbance is highly prevalent (89.5%) and is associated with increased opioid consumption and prolonged hospital length of stay. The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 34/100 (low).
The Claim
Postoperative sleep disturbance is highly prevalent (89.5%) and is associated with increased opioid consumption and prolonged hospital length of stay.
This conclusion is most relevant to: 143 adult patients undergoing elective surgery under general anesthesia at a tertiary care center..
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸The prevalence, predictors, and clinical impact of postoperative sleep disturbance: A prospective cohort study. (Saudi journal of anaesthesia, 2026) —
How It Works
The proposed biological pathway:
- ▸Surgery and anesthesia disrupt normal sleep architecture
- ▸Environmental factors (noise, light, nursing interventions) in hospital contribute to poor sleep
- ▸Poor sleep leads to increased pain perception and opioid requirements
- ▸Increased opioid use and poor sleep prolong recovery and hospital stay
Who Might Benefit
Evidence fit by population:
- ▸143 adult patients undergoing elective surgery under general anesthesia at a tertiary care center.
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Observational design cannot establish causality
- ▸Single-center study with relatively small sample size (n=143)
- ▸Sleep quality assessed only on first postoperative morning, not over full hospital stay
- ▸Modified PSQI not validated for postoperative setting
Frequently Asked Questions
What is the prevalence of postoperative sleep disturbance?▼
89.5% of patients (128 out of 143) had poor sleep quality on the first postoperative morning.
Is postoperative sleep disturbance associated with opioid use?▼
Yes, higher global PSQI scores were significantly correlated with higher 24-hour opioid consumption (r=0.41, P<0.001).
Does poor sleep after surgery affect hospital length of stay?▼
Yes, patients with poor sleep had a median LOS of 4 days compared to 3 days for good sleepers (P=0.018).
What are the main predictors of sleep duration after surgery?▼
Sleep disturbance (β=0.702), sleep efficiency (β=0.288), and sleep latency (β=0.224) were significant predictors, explaining 34.8% of variance.
