Topic: Risk, prevention and care in population studies

Objectives To examine the association between persistent delirium and 1-year mortality in newly admitted postacute care (PAC) facility patients with delirium who were followed regardless of residence. Design Observational cohort study. Setting Eight greater-Boston skilled nursing facilities specializing in PAC. Participants Four hundred twelve PAC patients with delirium at admission after an acute hospitalization. Measurements Assessments were done at baseline and four follow-up times: 2, 4, 12, and 26 weeks. Delirium, defined using the Confusion Assessment Method, was assessed, as were factors used as covariates in analyses: age, sex, comorbidity, functional status, and dementia. The outcome was 1-year mortality determined according to the National Death Index and corroborated using medical record and proxy telephone interview. Results Nearly one-third of subjects remained delirious at 6 months. Cumulative 1-year mortality was 39%. Independent of age, sex, comorbidity, functional status, and dementia, subjects with persistent delirium were 2.9 (95% confidence interval 51.9-4.4) times as likely to die during the 1-year follow-up as subjects whose delirium resolved. This association remained strong and significant in groups with and without dementia. Additionally, when delirium resolved, the risk of death diminished thereafter. Conclusion In patients who were delirious at the time of PAC admission, persistent delirium was a significant independent predictor of 1-year mortality.

Published in a peer-reviewed journal, and it is a cohort study following people over time. Scored zero for sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 30 of the 58 points we could judge it on, which is 52 out of 100.
