The coming of age of a joint elderly medicine-psychiatric ward: 18 years' experience

Organization and Outcomes of Integrated Inpatient Medical and Psychiatric Care Units: A Systematic Review

OBJECTIVE

The goal of this review was to assess the relationships among aims, designs, and outcomes of integrated inpatient medical and psychiatric care units (IMPUs) and gather the evidence base on the effectiveness of these units.

METHODS

Using online searches of Embase, Medline, Web of Science, PsycINFO, Scopus, CINAHL, Cochrane, and Google Scholar, the authors identified and reviewed literature describing the aims and outcomes of specific IMPU designs.

RESULTS

The search yielded 55 studies, in which the authors identified 39 IMPUs that focused on patients with mood, psychotic, somatic symptom, substance use, organic, and personality disorders and a broad array of medical diagnoses. Most units were psychiatric-medical units and had medium medical and psychiatric acuity capabilities. The studies reviewed provided little information on the cost-effectiveness of various IMPU designs. Although some comparative studies indicated reductions in hospital length of stay (LOS), these studies were generally of low quality and rarely reported other intended outcomes.

CONCLUSIONS

IMPUs may help shorten LOS. IMPUs should focus care on patients with complex conditions and high acuity to maximize health system value. Implementing compulsory admission facilities; qualified psychiatric, medical, and nursing staff involvement; and cross-disciplinary training may improve IMPUs' capacity to treat high-acuity patients. Future research should relate IMPU designs to intended outcomes.

[Trends in psychiatric admissions in adults over 65 years old]

BACKGROUND

The aim of this study was to analyse the trend in the percentages of elderly patients admitted to hospital for psychiatric reasons. An additional aim was to analyse the characteristics of the elderly population admitted to a psychiatric hospitalisation unit.

MATERIAL AN METHODS

An analysis was made of the trends in the percentages of discharges in elderly population at the national level and in the Mental Health Hospitalisation Unit (MHHU) of the Regional University Hospital of Malaga for a period of at least 18years using segmented regression. For the study of the characteristics of the elderly population, all patients (N=5,925) and consecutive episodes of admission (N=15,418) were compared between 1999 and 2017 in the MHHU.

RESULTS

At the national level, there was an increase in hospital discharges in elderly patients with a significant mean annual percent change of 2.0%. In the study unit, the elderly population were more frequently female, involuntarily admitted, and had a longer hospital stay. They had been diagnosed more frequently with organic and depressive mental disorders, and less frequently with schizophrenia, substance use, and personality disorders.

CONCLUSIONS

There was a growing trend in the percentage of elderly psychiatric patients admitted to hospitals during the study period. These results point to the increase in elderly psychiatric admissions and thus the need to adapt psychiatric units to the characteristics of this population.

The scientific evidence for a potential link between confusion and urinary tract infection in the elderly is still confusing - a systematic literature review

Background

Non-specific symptoms, such as confusion, are often suspected to be caused by urinary tract infection (UTI) and continues to be the most common reason for suspecting a UTI despite many other potential causes. This leads to significant overdiagnosis of UTI, inappropriate antibiotic use and potential harmful outcomes. This problem is particularly prevalent in nursing home settings.

Methods

A systematic review of the literature was conducted assessing the association between confusion and UTI in the elderly. PubMed, Scopus and PsychInfo were searched with the following terms: confusion, delirium, altered mental status, acute confusional state, urinary tract infection, urine infection, urinary infection and bacteriuria. Inclusion criteria and methods were specified in advance and documented in the protocol, which was published with PROSPERO (registration ID: CRD42015025804). Quality assessment was conducted independently by two authors. Data were extracted using a standardised extraction tool and a qualitative synthesis of evidence was made.

Results

One thousand seven hunderd two original records were identified, of which 22 were included in the final analysis. The quality of these included studies varied, with frequent poor case definitions for UTI or confusion contributing to large variation in results and limiting their validity. Eight studies defined confusion using valid criteria; however, no studies defined UTI in accordance with established criteria. As no study used an acceptable definition of confusion and UTI, an association could not be reliably established. Only one study had acceptable definitions of confusion and bacteriuria, reporting an association with the relative risk being 1.4 (95% CI 1.0–1.7, p = 0.034).

Conclusions

Current evidence appears insufficient to accurately determine if UTI and confusion are associated, with estimates varying widely. This was often attributable to poor case definitions for UTI or confusion, or inadequate control of confounding factors. Future well-designed studies, using validated criteria for UTI and confusion are required to examine the relationship between UTI and acute confusion in the elderly. The optimal solution to clarify this clinical issue would be a randomized controlled trial comparing the effect of antibiotics versus placebo in patients with new onset or worsening confusion and presence of bacteriuria while lacking specific urinary tract symptoms.

Joint geriatric and psychiatric wards: a review of the literature

Joint geriatric/psychiatric wards are a potential solution to improving care of older patients with both psychiatric and medical illnesses in acute hospitals. A literature search using Medline, PsycINFO, Embase and CINAHL between 1980 and 2010 was carried out for information about joint wards for older people. Thirteen relevant papers were identified. These wards share common characteristics and there is evidence that they may reduce length of stay and be cost-effective, but there are no high-quality randomised controlled trials. Further research is needed, particularly regarding cost-effectiveness.
