Excess mortality among elderly psychiatric in-patients with organic mental disorder

Psychiatric symptoms and mortality in older adults with major psychiatric disorders: results from a multicenter study

Prior research suggests that certain psychiatric symptoms could be associated with increased risk of death. However, it remains unclear whether this association could rely on all or specific symptoms. In this report, we used data from a multicenter 5-year prospective study (N = 641) of older adults with an ICD-10 diagnosis of schizophrenia, bipolar disorder or major depressive disorder, recruited from French community psychiatric departments. We used a latent variable approach to disentangle the effects shared by all psychiatric symptoms (i.e., general psychopathology factor) and those specific to individual psychiatric symptoms, while adjusting for sociodemographic and clinical factors. Psychiatric symptoms were assessed face-to-face by psychiatrists trained to semi-structured interviews using the Brief Psychiatric Rating Scale (BPRS). Among older adults with major psychiatric disorders, we found that all psychiatric symptoms were associated with increased mortality, and that their effect on the 5-year mortality were exerted mostly through a general psychopathology dimension (β = 0.13, SE = 0.05, p < 0.05). No BPRS item or lower order factor had a significant effect on mortality beyond and above the effect of the general psychopathology factor. Greater number of medical conditions, older age, male sex, and being hospitalized or institutionalized at baseline were significantly associated with this risk beyond the effect of the general psychopathology factor. Since psychiatric symptoms may affect mortality mainly through a general psychopathology dimension, biological and psychological mechanisms underlying this dimension should be considered as promising targets for interventions to decrease excess mortality of older individuals with psychiatric disorders.

Excess mortality and risk factors for mortality among patients with severe mental disorders receiving home care case management

AIM

Home care case management (CM) is the main intervention for patients with severe mental disorders (SMDs) requiring outreach care. This study investigated the long-term mortality outcome and associated risk factors in patients who received home care CM.

METHODS

This nationwide study enrolled patients who received home care CM (n = 10,255) between 1 January 1999 and 31 December 2010. Each patient was followed up from the baseline (when patients underwent home case CM for the first time during the study period) to the censor (i.e. mortality or the end of the study). We calculated the standardized mortality ratio (SMR) and presented by age and diagnosis. Multivariate regression was performed to assess independent risk factors for mortality.

RESULTS

Among 10,255 patients who received home care CM, 1409 died during the study period; the overall SMR was 3.13. Specifically, patients with organic mental disorder had the highest SMR (4.98), followed by those with schizophrenia (3.89), major depression (2.98), and bipolar disorder (1.97). In the multivariate analysis, patients with organic mental disorder or dementia had the highest risk, whereas the mortality risk in patients with schizophrenia was comparable to that in patients with bipolar disorder or major depression. Deceased patients had a significantly higher proportion of acute or chronic physical illnesses, including cancer, chronic hepatic disease, pneumonia, diabetes mellitus, cardiovascular disease, and asthma.

CONCLUSION

This study presented the gap of mortality in patients with SMDs receiving home care CM in Taiwan. We highlight the need for effective strategies to improve medical care for this specified population.

Mortality After Ischemic Stroke in Patients with Alzheimer's Disease Dementia and Other Dementia Disorders

BACKGROUND

Stroke and dementia are interrelated diseases and risk for both increases with age. Even though stroke incidence and age-standardized death rates have decreased due to prevention of stroke risk factors, increased utilization of reperfusion therapies, and other changes in healthcare, the absolute numbers are increasing due to population growth and aging.

OBJECTIVE

To analyze predictors of death after stroke in patients with dementia and investigate possible time and treatment trends.

METHODS

A national longitudinal cohort study 2007-2017 using Swedish national registries. We compared 12,629 ischemic stroke events in patients with dementia with matched 57,954 stroke events in non-dementia controls in different aspects of patient care and mortality. Relationship between dementia status and dementia type (Alzheimer's disease and mixed dementia, vascular dementia, other dementias) and death was analyzed using Cox regressions.

RESULTS

Differences in receiving intravenous thrombolysis between patients with and without dementia disappeared after the year 2015 (administered to 11.1% dementia versus 12.3% non-dementia patients, p = 0.117). One year after stroke, nearly 50% dementia and 30% non-dementia patients had died. After adjustment for demographics, mobility, nursing home placement, and comorbidity index, dementia was an independent predictor of death compared with non-dementia patients (HR 1.26 [1.23-1.29]).

CONCLUSION

Dementia before ischemic stroke is an independent predictor of death. Over time, early and delayed mortality in patients with dementia remained increased, regardless of dementia type. Patients with≤80 years with prior Alzheimer's disease or mixed dementia had higher mortality rates after stroke compared to patients with prior vascular dementia.

Mortalidade em pacientes psiquiátricos: revisão bibliográfica

OBJETIVO: Avaliar as informações referentes às taxas de mortalidade em pacientes psiquiátricos publicadas na literatura científica. MÉTODOS: Nesta revisão bibliográfica (bases de dados, sites e periódicos especializados) foram selecionados estudos descritivos e interpretativos que avaliaram as seguintes dimensões: caracterização sociodemográfica, co-morbidades clínicas, tempo de tratamento e diagnósticos relacionados à mortalidade psiquiátrica. As bases de dados avaliadas foram Medline, SciELO e LILACS. RESULTADOS: Os estudos selecionados sobre o tema sugerem que indivíduos com transtornos mentais maiores têm menor tempo de sobrevida em relação à população geral, e há diferenças significativas de mortalidade entre pacientes institucionalizados e aqueles que freqüentam serviços extra-hospitalares. A política de desinstitucionalização do paciente psiquiátrico, que se iniciou no último século, tem causado redução dos leitos psiquiátricos em todos os países; seus efeitos para a saúde geral dos doentes mentais ainda não estão muito claros e necessitam de mais investigações. CONCLUSÃO: É necessária a implantação de intervenções preventivas e terapêuticas que visem à saúde geral dos pacientes psiquiátricos em todos os níveis de assistência de saúde mental.

Total mortality in people admitted to a psychiatric hospital

BACKGROUND

The aim was to document the mortality of psychiatric patients within a service system characterised by a low beds-to-population ratio.

METHOD

All patients admitted to one psychiatric hospital were followed from date of first admission after 31 July 1980 until 31 December 1992 with regard to death, by linkage to the Norwegian Central Register of Persons. Age-adjusted total mortality rates and standardised mortality ratios (SMRs) compared with the general population were computed.

RESULTS

Mortality rates were highest in men, and increased with age in both sexes. SMRs were highest in the younger age-groups, and the overall SMR was significantly higher for men than for women. Mortality was highest during the first year after admission for both sexes and was higher than in the general population in all diagnostic groups.

CONCLUSIONS

The mortality of psychiatric patients is still unsatisfactorily high, and men constitute a special high-risk group.
