Geriatric Patients Improve as Much as Younger Patients from Hospitalization on General Psychiatric Units

Pre-discharge factors predicting readmissions of psychiatric patients: a systematic review of the literature

BACKGROUND

Readmission rate is considered an indicator of the mental health care quality. Previous studies have examined a number of factors that are likely to influence readmission. The main objective of this systematic review is to identify the studied pre-discharge variables and describe their relevance to readmission among psychiatric patients.

METHODS

Studies on the association between pre-discharge variables and readmission after discharge with a main psychiatric diagnosis were searched in the bibliographic databases Ovid Medline, PsycINFO, ProQuest Health Management and OpenGrey. Relevant publications published between January 1990 and June 2014 were included. For each variable, the number of papers that considered it as a predictor of readmission and that found a significant association was recorded, together with the association direction and whether it was found respectively in bivariate and in multivariate analyses.

RESULTS

Of the 734 articles identified in the search, 58 papers were included in this review, mainly from the USA and concerning patients with severe mental disorders. Analysed variables were classified according to the following categories: patients' demographic, social and economic characteristics; patients' clinical characteristics; patients' clinical history; patients' attitude and perception; environmental, social and hospital characteristics; and admission and discharge characteristics. The most consistently significant predictor of readmission was previous hospitalisations. Many socio-demographic variables resulted as influencing readmission, but the results were not always homogeneous. Among other patients' clinical characteristics, diagnosis and measures of functional status were the most often used variables. Among admission characteristics, length of stay was the main factor studied; however, the results were not very consistent. Other relevant aspects resulted associated with readmission, including the presence of social support, but they have been considered only in few papers. Results of quality assessment are also reported in the review. The majority of papers were not representative of the general psychiatric population discharged from an inpatient service. Almost all studies used multivariate analytical methods, i.e., confounders were controlled for, but only around 60% adjusted for previous hospitalisation, the variable most consistently considered associated to readmission in the literature.

CONCLUSIONS

The results contribute to increase knowledge on pre-discharge factors that could be considered by researchers as well as by clinicians to predict and prevent readmissions of psychiatric patients. Associations are not always straightforward and interactions between factors have to be considered.

A population-based comparison of the use of acute healthcare services by older adults with and without mental illness diagnoses

Older adults with mental illness (MI) are a highly vulnerable population and need to be provided healthcare services in a timely and thorough way. Compared with older adults without MI, older adults with MI spend a great deal of time being hospitalized and hence costing millions of dollars because the care they need is often overlooked and/or not provided. While they end up spending too much time in hospital, in the emergency department and getting readmitted to hospital because of their MI, this could have been prevented or lessened if an adequate assessment and treatment regime was done by clinicians who were well informed on the topic of older adults' mental health. Older adults with MI are also more likely to leave hospital for long-term care settings, to die and to have more sickness compared with older adults who do not have MI. Further, they are also more likely to be admitted to hospital on an urgent, unplanned basis. How older adults with MI use acute hospitals is important for psychiatric nurses to know and understand, as they can help to provide the care needed so they do not have to be in hospital for long periods of time. Psychiatric nurses can share much support and information on making sure older adults with MI are accurately care for when needed. To explore and compare predictors of hospital length of stay (LOS), acute LOS (ALOS), emergency room (ER) wait times, rate of readmission (ROR) and costs of inpatient hospital care for older adults with and without mental illness (MI) diagnoses in the province of Newfoundland and Labrador (NL). This descriptive-comparative study used aggregate population level data of 12,283 people aged 65 years and older admitted to an acute care hospital in the province of NL. A total of 8.3% of hospitalized older adults had MI diagnoses. Older adults with MI diagnoses had a significantly longer LOS, ALOS, ROR, ER wait time and costs compared with older adults without MI diagnoses, after controlling for medical co-morbidities. Key variables such as patient demographics, admission indicators, discharge indicators and other medical co-morbidities had differential impacts on observed service use. While only a small percentage of hospitalized older adults had MI diagnoses, the use and cost of acute hospitalizations was significantly greater than that of older adults without MI diagnoses.

Two years' outcome of acute mania in bipolar disorder: different effects of age and age of onset

BACKGROUND

Information about differences between younger and older patients with bipolar disorder and between older patients with early and late age of onset of illness during long-term treatment is scarce.

OBJECTIVES

This study aimed to investigate the differences in treatment and treatment outcome between older and younger manic bipolar patients and between early-onset bipolar (EOB) and late-onset bipolar (LOB) older patients.

METHOD

The European Mania in Bipolar Longitudinal Evaluation of Medication study was a 2-year prospective, observational study in 3459 bipolar patients on the treatment and outcome of patients with an acute manic or mixed episode. Patients were assessed at 6, 12, 18, and 24 months post-baseline. We calculated the number of patients with a remission, recovery, relapse, and recurrence and the mean time to achieve this.

RESULTS

Older patients did not differ from younger bipolar patients in achieving remission and recovery or suffering a relapse and in the time to achieve this. However, more older patients recurred and in shorter time. Older patients used less atypical antipsychotics and more antidepressants and other concomitant psychiatric medication. Older EOB and LOB patients did not differ in treatment, but more older LOB patients tended to recover than older EOB patients.

CONCLUSION

Older bipolar manic patients did not differ from younger bipolar patients in short-term treatment outcome (remission and recovery), but in the long term, this may be more difficult to maintain. Distinguishing age groups in bipolar study populations may be useful when considering treatment and treatment outcome and warrants further study.

Associations among fluid intake, cognitive function, and length of stay in psychogeriatric inpatients

PURPOSE

The purpose of this study was to examine differences, interactions, and associations among cognition, fluid intake, and demographic variables that may affect length of stay (LOS) for psychogeriatric inpatients aged 65 years or older.

DESIGN AND METHODS

Descriptive, comparative, correlational secondary analysis of data from a primary study of 202 inpatients.

FINDINGS

Older adults with and without cognitive impairment had different fluid intake over time (F = 3.50; p = .03), but had no difference in LOS in relation to cognitive functioning (p = .23); additional factors may predict LOS.

PRACTICE IMPLICATIONS

Care providers must monitor the fluid intake of elderly patients with and without cognitive impairment throughout their hospitalization.

Characteristics of older adults hospitalized in acute psychiatric units in ontario: a population-based study

OBJECTIVE

As the numbers of older adults in Canada increases, there will be a growing need for mental health services for this population. Acute psychiatric units (APUs) provide inpatient psychiatric services for the management of serious mental illness. Understanding the characteristics of older adults in APUs is necessary to determine the range of inpatient services required for this population.

METHOD

We conducted a population-based study of all adults discharged from APUs in Ontario in a 2-year period, 2008-2010, using administrative databases. We compared the characteristics of older adults (aged 66 years and older) in APUs to those of younger adults (aged 18 to 65 years), including sociodemographics, psychiatric and medical diagnoses, and measures of cognition and functioning.

RESULTS

There were a total of 79 352 discharges from APUs, with older adults accounting for 8.8% of all discharges. Depressive disorder was the most common diagnosis, both in older and in younger populations (32.1% and 29.9%, respectively), while dementia accounted for 19.5% of discharges for older adults. Older adults, compared with younger adults, were more likely to have 2 or more chronic medical conditions (83.8% and 20.5%, respectively), significant cognitive impairment (47.0% and 14.5%, respectively), and moderate-to-severe functional impairment (21.8% and 3.3%, respectively).

CONCLUSIONS

Older adults in APUs are a complex group, with mental health and medical care needs that differ from younger adults. APUs must be able to provide adequate psychiatric, medical, and interprofessional services to achieve optimal outcomes. Future studies are required to understand the quality of care and outcomes for older adults in APUs.

Determinants of length of stay for psychiatric inpatients: analysis of a national database covering the entire Korean elderly population

OBJECTIVE

In a rapidly aging society, inappropriately long geropsychiatric inpatient hospitalization is a challenging concern for mental health policy-makers and researchers. This study aimed to investigate patient and institutional factors affecting geropsychiatric inpatient length of stay (LOS), providing an overview of current geropsychiatric health care system in South Korea.

METHODS

This retrospective, population-based, cross-sectional study analysed nationwide reimbursement claim databases covering the entire elderly population of Korea between January 2005 and June 2006. Given the nested structure of the data, a multivariate multilevel regression analysis was performed.

RESULTS

The average LOS was 128 days. Males, patients with schizophrenia, and those enrolled in a National Medical Care Aid program tended to have longer hospital stays. Patient age was negatively related to LOS. Institutional variables related to longer hospitalizations included a psychiatric hospital, a higher number of beds, fewer human resource employees, a higher proportion of male, oldest old, and patients with dementia.

CONCLUSIONS

Our results suggest that policies targeting geropsychiatric patients diagnosed with schizophrenia, enrolled in National Medical Care Aid programs, and admitted to psychiatric hospitals could reduce LOS. Additionally, the impact of the patient composition of a medical institution on LOS needs to be closely investigated.
