To estimate and compare the prevalence and incidence of delirium and its risk factors in residents of Dutch nursing homes and residential care homes.
Data were extracted from the Long-Term Care Facility (inter RAI-LTCF) version of the Resident Assessment Instrument, which was filled in a routine care cohort for a total of 3627 residents. 828 residents of six nursing homes and 1365 residents of 23 residential homes were included in the analyses. Delirium was defined as a positive score on the adjusted Nursing Home-CAM.
The prevalence of delirium was 8.9% in the nursing homes and 8.2% in the residential homes. The incidence was highest in the nursing homes with 20.7 versus 14.6 per 100 person-years. Multivariate tests of risk factors for developing delirium included chair restraints (OR 2.3; 95% CI 1.27-4.28), dementia (odds ratio (OR) 3.3; 95% confidence interval (CI) 2.03-5.24) and Parkinson's disease (OR 2.3; 95% CI 0.96-5.63) for residents in nursing homes, and dementia (OR 1.8; 95% CI 1.31-2.55) and fall incidents (OR 1.7; 95% CI 1.20-2.48) for residents in residential care homes.
The prevalence and incidence of delirium was high in both nursing homes and residential care homes. More focus on modifiable risk factors such as the use of restraints in nursing homes and fall incidents in residential care homes may help to prevent delirium.

    ABSTRACT: Aims: This study aimed to clarify the accuracy of the Palliative Prognostic Index (PPI) for advanced cancer patients in home care settings. Method: The study included 65 advanced cancer patients who received home visiting services between April 2007 and June 2009, and who died at home or in the hospital. Using the medical records from initial home visits, we retrospectively calculated PPI scores along with sensitivity and specificity. Results: For 3- and 6-week survival, prognostic prediction demonstrated respective sensitivities of 55% and 63%, and specificities of 79% and 77%. Conclusion: The sensitivity of the PPI for advanced cancer patients in home care settings was lower than reported for those in palliative care units. Development of prognostic tools suitable for home care settings is needed.

    ABSTRACT: Delirium ("acute confusional state"), characterized by an acute decline in attention and cognition, is a common clinical syndrome in elderly patients. The prevalence of delirium increases with age, and is highest among hospitalized older patients. A systematic literature search of MEDLINE, EMBASE, and the Cochrane Library limited to the period 2000-2012 was conducted. The antecedent of delirium is often multifactorial, the development involving a complex interrelationship between a vulnerable patient with predisposing factors and exposure to precipitating events. Important predisposing factors include high age, cognitive impairment, comorbidity, sensory impairment, and low Body Mass Index (BMI). Infections, cardiovascular events, trauma/fracture, surgery, stroke, metabolic abnormalities, and dehydration, are all recognized as precipitating factors. Delirium is associated with negative outcomes like cognitive decline, increased morbidity and mortality, and should be prevented. Prevention and treatment of delirium is multifactorial and multidisiplinary, focusing on the treatment of factors precipitating and maintaining the delirium. No pharmacological treatment has so far demonstrated significant efficacy. The knowledge of risk factors and the underlying patho physiological mechanisms involved remains scarce, and further research is warranted to explore the mechanisms and thereby develop targeted prevention and treatment strategies.
