Racial and Socioeconomic Disparities in Palliative Care Utilization Among Patients with In-Hospital Mortality After Mechanical Thrombectomy for Stroke.

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
background and purposeDespite advances in mechanical thrombectomy (MT), in-hospital mortality remains approximately 10-15%. Palliative care (PC) improves end-of-life quality, yet limited research has been conducted on PC disparities specifically among patients with in-hospital mortality after MT. We examined racial and socioeconomic disparities in PC utilization among patients who died following MT for acute ischemic stroke.
methodsThis retrospective cohort study used the National Inpatient Sample (2016-2022). We included adults ≥ 18 years who underwent MT for acute ischemic stroke and died during hospitalization. Primary exposures were race/ethnicity and median household income quartile for patient ZIP code. The primary outcome was receipt of PC, identified by ICD-10-CM code Z51.5. Survey-weighted multivariable logistic regression adjusted for age, sex, insurance, income and calendar year.
resultsAmong 4495 patients who died after MT (weighted N ~ 22,000; mean age 72.5 years; 49.3% female), overall PC utilization was 63.5%. PC rates varied by race: white 66.8%, Black 51.9%, and Hispanic 55.1%. In adjusted analyses, Black patients (adjusted odds ratio [aOR] 0.59, 95% CI 0.48-0.74) and Hispanic patients (aOR 0.64, 95% CI 0.49-0.82) had significantly lower odds of receiving PC compared with white patients. Lower neighborhood income was associated with decreased PC utilization (Low vs. High income: aOR 0.82, 95% CI 0.70-0.95). In intersectional analyses, low-income Black/Hispanic patients had the lowest PC receipt (aOR 0.50, 95% CI 0.40-0.62). Results were robust in sensitivity analyses.
conclusionsAmong adults with in-hospital mortality after MT for acute ischemic stroke, Black and Hispanic race/ethnicity and residence in lower-income neighborhoods were independently associated with lower odds of receiving a palliative care encounter. These associations persisted across multiple sensitivity analyses and were most pronounced among low-income minoritized patients. The administrative nature of the data limits causal interpretation, but these findings support further investigation into modifiable contributors to inequitable palliative care access after stroke intervention.
