Risk factors for delirium occurring after deep brain stimulation surgery in patients with Parkinson's disease.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivePostoperative delirium (POD) may cause cognitive morbidities and prolonged hospital stay. This study aimed to evaluate the risk factors associated with postoperative delirium in patients undergoing deep brain stimulation (DBS) for Parkinson's disease (PD).
methodWe retrospectively reviewed 83 patients with idiopathic PD who underwent bilateral DBS between 2016 and 2023. The target of DBS was the globus pallidus interna (Gpi) or the subthalamic nucleus (STN) in 84.3% and 15.7% of patients, respectively. Patients were evaluated using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and categorized into two groups: those with delirium and those without. Demographic features, disease duration, preoperative cognitive status (Mini-Mental State Examination) and silent ischemia, brain atrophy rates, DBS target location, surgical type and duration, Unified PD Rating Scale-3 scores, Hoehn and Yahr scores, postoperative perilead edema, and electrolyte imbalance were compared between patients with and without post-DBS delirium. Apart from univariate analysis, receiver operating characteristic (ROC) curve analysis for disease duration and multivariate logistic regression analyses were used to determine independent risk factors for post-DBS delirium.
resultsFive out of the 83 patients (6%) developed post-DBS delirium. Age (> 68 years), disease duration, preoperative cerebral atrophy rates, and postoperative perilead edema were significantly higher in patients who developed delirium (p < 0.05 each). The ROC curve analysis revealed disease duration of ≥ 11 years as a risk factor for delirium (p = 0.001; odds ratio, OR: 58.4, 95% confidence interval, CI: 5.45-625.49). Age and disease duration were independent risk factors for post-DBS delirium (OR: 1.243, 95% CI: 1.070-1.592 and OR: 22.52, 95% CI: 1.21-383.96, respectively).
conclusionsOlder age and longer disease duration are independent risk factors for postoperative delirium in patients with PD. This study highlights the need to identify high-risk patients when undertaking DBS to facilitate early diagnosis and timely management.
