Patients With Dementia Undergoing High-Risk Inpatient Surgery Have Poor Outcomes.
Article in Journal of the American Geriatrics Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSurgery is common among patients living with dementia, and understanding outcomes may help decision-making. We compared patients' and utilization outcomes after high-risk surgery among patients with and without dementia.
methodsIn this retrospective national cohort study, we compared outcomes of Medicare fee-for-service beneficiaries 66 years or older who underwent high-risk inpatient surgery (i.e., with an inpatient mortality of at least 1%) from January 1, 2017 to September 30, 2018. We examined 90- and 30-day all-cause mortality, major complications, discharge to a higher level of care, intensive end-of-life interventions, and prolonged skilled nursing facility (SNF) stay. We used generalized estimating equations regression modeling and competing risks analysis.
resultsAmong 19,998,187 beneficiaries, we identified 859,570 who had fee-for-service coverage and were 66 years or older at the time of a high-risk surgery. Of these, 124,822 (14.5%) had a diagnosis of dementia. Female sex accounted for 81,252 (65.1%) of the dementia cohort. Four of five of the most common procedures were related to femur fracture and cardiac surgery in the dementia and non-dementia cohorts. Ninety-day mortality was worse among patients with dementia: 22.8% versus 9.3% (adjusted odds ratio [aOR] 1.82, 95% confidence interval [CI] 1.78-1.85). Patients with dementia were also more likely to have major complications (51.6% vs. 38.5%, aOR 1.19, 95% CI 1.17-1.20), be discharged to a higher level of care (75.1% vs. 41.3%, aOR 1.49, 95% CI 1.44-1.53), and have a prolonged SNF stay (3.7% vs. 1.4%, aOR 1.80, 95% CI 1.69-1.91). Although patients with ADRD were overall less likely to receive intensive interventions during the index admission and at 90 days, they were more likely to receive feeding tubes (aOR 1.22, 95% CI 1.17-1.28).
conclusionPersons living with dementia experience a broad range of worse outcomes after high-risk surgery compared to those without dementia. These data may be used for decision-making.
