Key Associations Found in the Struggle With Sleep in Lung Transplant Recipients.
Jane Simanovski, Jody Ralph, Sherry Morrell
PMID 39403772WHAT IT FOUND
Over half of lung transplant recipients reported poor sleep.
Anxiety symptoms were the only independent predictor of poor sleep in this group. Recent hospitalization and acute rejection treatment were linked to poor sleep in initial checks but lost significance when other factors were considered.
Key findings
0152.5% of participants reported poor sleep quality based on the Pittsburgh Sleep Quality Index.
02Higher anxiety scores were the only significant independent predictor of poor sleep in the multivariate model.
03Recent hospitalization and treatment for acute rejection were associated with poor sleep in bivariate analysis but not in the final model.

What it does not show
The study was conducted at a single center with a small sample size (61 participants), which limits generalizability. Sleep quality was assessed at a single point in time, so it cannot capture how sleep changes over the course of recovery. The survey did not collect data on pretransplant diagnoses or specific immunosuppressive medication doses, which are known to affect sleep. Self-reported data are subject to recall bias and social desirability bias. The study did not objectively measure sleep (e.g., via actigraphy or polysomnography), relying entirely on subjective perception.
Declared interests
The authors declared no conflicts of interest and received no external funding for this study.
The easy way to misread this
Do not assume that recent hospitalization or acute rejection treatment are the primary causes of poor sleep in lung transplant recipients. While these factors were associated with poor sleep in initial analyses, they were not significant in the multivariate model, where anxiety symptoms emerged as the only independent predictor.
