Psychiatric rehospitalization among elderly persons in the United States
ABSTRACT This study examined predictors of psychiatric rehospitalization among elderly persons.
Readmission within six months of an index hospitalization was modeled by using Medicare data on all hospitalizations with a primary psychiatric diagnosis in the first half of 2002 (N=41,839). Data were linked with state and community-level information from the U.S. census.
Twenty-two percent of beneficiaries were rehospitalized for psychiatric reasons within six months of discharge. After the analyses adjusted for sociodemographic factors, readmission was most likely among persons with a primary diagnosis of schizophrenia (hazard ratio [HR]=2.63), followed by bipolar disorder (HR=2.51), depression (HR=1.75), and substance abuse (HR=1.38) (reference group was "other" psychiatric conditions). A baseline hospital stay of five or more days for an affective disorder was associated with a reduced readmission hazard (HR=.68, relative to shorter stays), yet the opposite was true for a nonaffective disorder (HR=1.26). For persons with nonaffective disorders, an elevated hazard of readmission was associated with comorbid alcohol dependence (HR=1.32), panic disorder (HR=1.76), borderline personality disorder (HR=2.33), and drug dependence (HR=1.17). However, for persons with affective disorders, having a personality disorder other than borderline personality disorder or dependent personality disorder (HR=1.27) and having an "other" anxiety disorder (HR=1.15) were significantly associated with an increased risk of rehospitalization. Obsessive-compulsive disorder increased the readmission hazard in both groups.
Readmission risk factors may differ for affective disorders and nonaffective disorders. Very short hospitalizations were associated with increased risk of rehospitalization among persons with an affective disorder, which underscores the need for adequate stabilization of this group of patients during hospitalization. Results also highlight the specific types of comorbidities associated most strongly with rehospitalization risk.

ABSTRACT: Objectives. Readmission has a major role in the reduction of the quality of life and the increase in the years of lost life. The main objectives of this study were to answer to the following research questions. (a) What was the readmission rate? (b) What were the social, demographic, and clinical characteristics of patients admitted to the Psychiatric Emergency Service at Nour University Hospital, affiliated to Isfahan University of Medical Sciences, Isfahan, Iran? (c) What were the effective factors on readmission? Method. This cross-sectional study was conducted on a total number of 3935 patients who were admitted to Isfahan University Hospital Psychiatric Ward in Isfahan, Iran, from 2004 to 2010. Gender, age, marital status, education, self-report history of previous admission, type of psychiatric disorder, substance misuse, suicide, and the length of the current psychiatric disorder were collected from the registered medical files of patients. The data were analysed using the negative binomial regression model. Results. We found that factors such as psychiatric anxiety disorder, bipolar I, bipolar II, psychotic disorder, depression, and self report history of previous admission were statistically significant in the number of readmissions using the negative binomial model. Conclusion. Readmission to the psychiatric ward is mainly predictable by the type of diagnosis and psychosocial supports.03/2013; 2013:685625. DOI:10.1155/2013/685625

ABSTRACT: To explore the risks and rates of readmission and their predictors 14 days, one year, and five years after discharge for the psychiatric population in Taiwan. This was a prospective study based on claims from 44,237 first-time hospitalized psychiatric patients discharged in 2000, who were followed for up to five years after discharge. The cumulative incidence and incidence density of readmission were calculated for various follow-up periods after discharge, and Cox proportional hazard models were generated to identify the significant predictors for psychiatric readmission. The less than 14-day, one-year, and five-year cumulative incidences were estimated at 6.1%, 22.3%, and 37.8%, respectively. The corresponding figures for incidence density were 4.58, 1.04, and 0.69 per 1,000 person-days, respectively. Certain factors were significantly associated with increased risk of readmission irrespective of the length of follow-up, including male gender, length of hospital stay >15 days, economic poverty, a leading discharge diagnosis of schizophrenia/affective disorders, and residence in less-urbanized regions. Compared to children/adolescents, young adults (20-39 years) were significantly associated with increased risks of <one-year and <five-year readmissions, but not <14-day readmission. Additionally, hospital characteristics were significantly associated with increased risk of <14-day and <one-year readmission, but not with risk of <five-year readmission. This study found that the significant predictors for psychiatric readmission 14 days to five years after discharge were essentially the same except for patient's age and hospital accreditation level. This study also highlighted the importance of socioeconomic factors in the prediction of readmission.Clinics (São Paulo, Brazil) 05/2010; 65(5):481-9.

ABSTRACT: To evaluate the extent to which preexisting mental disorders influence diagnosis, treatment, and survival in older adults with colon cancer. Retrospective cohort study. The Surveillance, Epidemiology and End Results (SEER)-Medicare linked database. Eighty thousand six hundred seventy participants, aged 67 and older with a diagnosis of colon cancer. The association between the presence of a preexisting mental disorder and the stage of colon cancer at diagnosis, receipt of cancer treatment, and overall and colon cancer-specific mortality were assessed using Cox proportional hazards regression and logistic regression. Participants with mental disorders were more likely to have been diagnosed with colon cancer at autopsy (4.4% vs 1.1%; P<.001) and at an unknown stage of cancer (14.6% vs 6.2%; P<.001); to have received no surgery, chemotherapy, or radiation therapy (adjusted risk ratio (ARR)=2.09, 95% confidence interval (CI)=1.86-2.35); and to have received no chemotherapy for Stage 3 cancer (ARR=1.63, 95% CI=1.49-1.79). The rate of overall mortality (hazard ratio (HR)=1.33, 95% CI=1.31-1.36) and colon cancer-specific mortality (HR=1.23, 95% CI=1.19-1.27) was substantially higher in participants with a preexisting mental disorder than in their counterparts. All of these associations were particularly pronounced in participants with psychotic disorders and those with dementia. Public health initiatives are needed to improve colon cancer detection and treatment in older adults with mental disorders.Journal of the American Geriatrics Society 07/2011; 59(7):1268-73.
