Prevalence of dementia and BPSD in community-dwelling older adults with advanced care needs: a nationwide survey in Taiwan.
Article in The journal of prevention of Alzheimer's disease, 2026. 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
backgroundCaring for people with both dementia and advanced care needs is complex. This study aimed to elucidate the prevalence of dementia and behavioral and psychological symptoms of dementia (BPSD) in patients receiving advanced care, including tube feeding, respiratory care, subcutaneous injection, urinary catheter, stoma care or enema, wound care, pain care, or dialysis.
methodsThis study was a nationwide, population-based, cross-sectional survey. A total of 11,297 participants were enrolled between September 2020 and June 2022 using a multistage stratified systematic sampling design. Dementia diagnosis was made by subspecialists during in-home visit or by expert consensus. The presence of BPSD and the use of specific advanced care services were collected by trained interviewers.
resultsOverall, 732 (6.5%) participants received at least one item of advanced care and 975 (8.6%) were diagnosed with dementia. Participants receiving advanced care had a higher prevalence of dementia (18.0%vs. 8.0%, p < 0.0001). Subjects receiving stoma or enema care (OR=4.92, 95% CI=2.29-10.59, p < 0.0001), tube feeding (OR=3.20, 95%CI=1.99-5.15, p < 0.0001), dialysis (OR=2.97, 95% CI=1.80-4.92, p < 0.0001), urinary catheterization or intermittent catheterization (OR=2.20, 95% CI=1.32-3.67, p = 0.003), and respiratory care (OR=2.01, 95% CI=1.14-3.57, p = 0.017) had a significantly higher risk of dementia. For BPSD, day-night confusion (42.0%vs. 27.9%, p = 0.002) and care-resistant behaviors (19.8%vs. 12.0%, p = 0.019) were significantly more prevalent in participants receiving advanced care.
conclusionsThis study found that patients receiving advanced care had a significantly higher prevalence of dementia and BPSD in Taiwanese population. Healthcare professionals should be vigilant regarding potential comorbid dementia in patients receiving advanced care and provide more patient-centered approaches or non-pharmacological interventions to alleviate BPSD and reduce care partner's loading.
