Impact of Cognitive Status at Skilled Nursing Facility Admission on Days Spent at Home Over the Year Following Traumatic Brain Injury Among Older Adults.
Article in Journal of the American Medical Directors Association, 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
objectivesOlder adults have the highest rates of traumatic brain injury (TBI)-related hospitalizations and deaths. Cognitive impairment is an acute consequence of TBI and may limit participation in rehabilitation. Older adults discharged to skilled nursing facilities (SNFs) after TBI may be particularly vulnerable to poor recovery. We examined whether cognitive status at SNF admission was associated with recovery in days spent at home (DAH) during the year following TBI hospitalization.
designRetrospective cohort study. SETTING AND
participantsA 20% sample of Medicare beneficiaries aged 65 and older hospitalized with TBI from 2017 to 2020 and discharged to an SNF linked to assessment data from the Minimum Data Set.
methodsCognitive status was evaluated using the Brief Interview for Mental Status (BIMS), present in the Minimum Data Set. BIMS 13 to 15 was categorized as not impaired, BIMS 8 to 12 as moderate impairment, and BIMS 0 to 7 as severe cognitive impairment. DAH were defined as days not spent in a facility or deceased. Negative binomial regression was used to model the adjusted association between BIMS category and DAH.
resultsOf 14,395 adults aged ≥65 years hospitalized with TBI and discharged to an SNF, 47.1% were cognitively intact, 30.2% had moderate cognitive impairment, and 22.7% had severe impairment. In adjusted models, compared with cognitively intact individuals, those with moderate [rate ratio, 0.82; 95% CI, 0.78-0.87] and severe (rate ratio, 0.64; 95% CI, 0.60-0.68) cognitive impairment had significantly fewer days at home during the year following TBI. CONCLUSIONS AND IMPLICATIONS: Cognitive impairment at SNF admission was associated with fewer DAH following TBI hospitalization, with a dose-response relationship across levels of impairment. Cognitive status at SNF admission appears to be an important marker of recovery trajectory following TBI. Future studies should investigate whether targeted rehabilitation interventions based on BIMS at SNF admission could improve recovery following TBI.
