Impact of pre-existing dementia on neurosurgical intervention and outcomes in older patients with head injury: an analysis of a nationwide trauma registry in Japan.
Observational study in Acta neurochirurgica, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDementia is a common comorbidity in older patients with traumatic brain injury (TBI), potentially affecting their care processes and outcomes. However, the impact of pre-existing dementia on TBI remains unclear as research on TBI often excludes older adults with comorbidities. This study aimed to investigate the association between pre-existing dementia and outcomes in older patients admitted to hospitals after TBI.
methodsThis observational study included patients aged ≥ 65 years with TBI who were identified from the Japan Trauma Data Bank between January 1, 2019, and December 31, 2021. Associations between pre-existing dementia and outcomes were assessed using multivariable logistic regression analysis. The primary outcome was survival at discharge. Secondary outcomes were neurosurgical interventions and discharge to home.
resultsIn total, 16,270 patients from 175 hospitals were analyzed. Of these, 1,750 (10.8%) had pre-existing dementia, and 13,520 (83.1%) survived to discharge. No significant association was observed between pre-existing dementia and neurosurgical interventions and survival at discharge. In contrast, pre-existing dementia was associated with a significantly lower likelihood of being discharged to home. Subgroup analysis revealed interactions between pre-existing dementia and the subgroups, showing adverse impact in relatively younger patients and those without severe head injury.
conclusionsPatients with pre-existing dementia had similar chances for neurosurgical intervention and survival at discharge than their counterparts without dementia. However, pre-existing dementia was associated with a significantly lower likelihood of being discharged to home, especially in relatively younger patients and those without severe head injury. Therefore, recognizing the risks within this population and taking measures to facilitate social reintegration is necessary.
