Delirium is common in medical in-patients and has serious adverse effects on mortality, functional outcomes, LOS and institutionalisation. The development of appropriate strategies to improve its management should be a clinical and research priority. As delirium prevalent at hospital admission is a significant problem, research is also needed into preventative measures that could be applied in community settings.
Background. Hip fracture is common in the elderly. Previous studies suggest that psychiatric illness
is common and predicts poor outcome, but have methodological weaknesses. Further studies are
required to address this important issue.Methods. We prospectively recruited 731 elderly participants with hip fracture in two Leeds
hospitals. Psychiatric diagnosis was made within 5 days of surgery using the Geriatric Mental State
schedule and other standardized instruments, and data on confounding factors was collected. Main
study outcomes were length of hospital stay, and mortality over 6 months after fracture.Results. Fifty-five per cent of participants had cognitive impairment (dementia in 40% and
delirium in 15%), 13% had a depressive disorder, 2% had alcohol misuse and 2% had other
psychiatric diagnoses. Participants were likely to remain in hospital longer if they suffered from
dementia, delirium or depression. The relative risks of mortality over 6 months after hip fracture
were increased in dementia and delirium, but not in depression.Conclusions. Psychiatric illness is common after hip fracture, and has significant effects on
important outcomes. This suggests a need for randomized, controlled trials of psychiatric
interventions in the elderly hip fracture population.
IMPORTANCE There is little evidence to guide management of depressive symptoms in older people. OBJECTIVE To evaluate whether a collaborative care intervention can reduce depressive symptoms and prevent more severe depression in older people. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial conducted from May 24, 2011, to November 14, 2014, in 32 primary care centers in the United Kingdom among 705 participants aged 65 years or older with Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) subthreshold depression; participants were followed up for 12 months. INTERVENTIONS Collaborative care (n=344) was coordinated by a case manager who assessed functional impairments relating to mood symptoms. Participants were offered behavioral activation and completed an average of 6 weekly sessions. The control group received usual primary care (n=361). MAIN OUTCOMES AND MEASURES The primary outcome was self-reported depression severity at 4-month follow-up on the 9-item Patient Health Questionnaire (PHQ-9; score range, 0-27). Included among 10 prespecified secondary outcomes were the PHQ-9 score at 12-month follow-up and the proportion meeting criteria for depressive disorder (PHQ-9 score Ն10) at 4-and 12-month follow-up. RESULTS The 705 participants were 58% female with a mean age of 77 (SD, 7.1) years. Four-month retention was 83%, with higher loss to follow-up in collaborative care (82/344 [24%]) vs usual care (37/361 [10%]). Collaborative care resulted in lower PHQ-9 scores vs usual care at 4-month follow-up. The proportions of participants meeting criteria for depression at 4-month follow-up were 17.2% (45/262) vs 23.5% (76/324), respectively (difference, −6.3% [95% CI, −12.8% to 0.2%]; relative risk, 0.83 [95% CI, 0.61-1.27]; P = .25) and at 12-month follow-up were 15.7% (37/235) vs 27.8% (79/284) (difference, −12.1% [95% CI, −19.1% to −5.1%]; relative risk, 0.65 [95% CI, 0.46-0.91]; P = .01). Collaborative Care Usual Care Difference (95% CI) P Value PHQ-9 score, mean At 4 mo (primary outcome) 5.36 6.67 −1.31 (−1.95 to −0.67) <.001 At 12 mo 5.93 7.25 −1.33 (−2.10 to −0.55) .001 CONCLUSIONS AND RELEVANCE Among older adults with subthreshold depression, collaborative care compared with usual care resulted in a statistically significant difference in depressive symptoms at 4-month follow-up, of uncertain clinical importance. Although differences persisted through 12 months, findings are limited by attrition, and further research is needed to assess longer-term efficacy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
