Impact of dementia on hospitalization

In-Hospital Mortality in Patients with and without Dementia across Age Groups, Clinical Departments, and Primary Admission Diagnoses

BACKGROUND

Studies have reported higher in-hospital mortality rates in patients living with dementia (PlwD) with limited evidence across age groups, clinical departments, and admission diagnoses. The aim of this study was to compare the in-hospital mortality rate of PlwD with patients without dementia across groups, clinical departments, and admission diagnoses.

METHODS

This case-control study included patients aged ≥ 60 years hospitalized in 1 of 14 German hospitals between January 2019 and July 2023. PlwD were matched to patients without dementia. The associations between dementia and in-hospital mortality across groups were assessed using univariable logistic regression analyses.

RESULTS

15,956 patients with and 15,956 without dementia were included (mean age: 83.9 years, 60.7% female). PlwD had a significantly higher in-hospital mortality rate (14.0% vs. 11.7%; OR 1.24, 95% CI: 1.16-1.32) than non-dementia controls. The highest excess mortality rate was observed in the youngest age group (60-70 years: 10.9% vs. 5.7%; OR: 2.05, 95% CI: 1.30-3.24), decreased with age, and became non-significant in the oldest age group (≥90 years: 16.2% vs. 17.3%; OR: 0.93, 95% CI: 0.80-1.08). Significant differences were found for digestive system disorders (OR: 1.59; 95% CI: 1.15-1.89), cardiovascular and cerebrovascular disorders (OR: 1.51; 95% CI: 1.30-1.75), endocrine, nutritional, and metabolic diseases (OR: 1.42; 95% CI: 1.06-1.90), and pneumonia (OR: 1.20; 95% CI: 1.04-1.37), as well as for all clinic departments except for geriatric departments.

CONCLUSION

The excess mortality rate was highest in younger age groups, where the general mortality and complication rate is relatively low in the general population. Appropriate approaches are needed, especially in non-geriatric wards.

Mortality in the Oldest-Old Adults After Discharge From Acute Geriatric Ward

Aim: To examine risk factors for post-discharge mortality in the oldest-old patients. Methods: We have assessed the risk factors for mortality after discharge from acute geriatric ward in 448 patients aged ≥90. Results: Low albumin, high urea, and full dependence were risk factors for mortality within 1 month and within 1 year after discharge from hospital. Age-adjusted Charlson Comorbidity Index score, neuroleptic drug treatments and frailty were specific risk factors for post-discharge mortality within 1 year. By Cox regression analysis, the risk factors associated with higher hazard ratios for post-discharge mortality within 14 years follow-up were age-adjusted Charlson Comorbidity Index score, poor functional status, anemia and dementia as comorbidities, neuroleptic drug treatments, low albumin, high urea, and high vitamin B12. Conclusion: Optimal treatment of the condition due to which the patient has been hospitalized and of the medical complications that occurred during hospitalization, while preventing functional decline, might secure longer post-discharge survival.

[Reasons for hospitalization of people with dementia-A scoping review]

BACKGROUND

Hospitalization represents a high burden for people with dementia, which can accelerate the decline of cognitive and motor skills. Behavioral changes and orientation problems may be increased in people with dementia during hospitalization. Some hospitalizations are potentially preventable by improved outpatient care.

OBJECTIVE

To provide an up to date overview of the most common reasons for hospitalization of people with dementia or mild cognitive impairment.

MATERIAL AND METHODS

A systematic literature search was conducted in the databases PubMed®, CINAHL and PsycINFO® in May 2020 to conduct the scoping review. Studies in German and English published between July 2010 and May 2020 were included.

RESULTS

The most common reasons for hospitalization, which were named in the 14 included studies, were infectious diseases, especially respiratory infections and urinary tract infections, cardiovascular diseases (in general or specific, e.g. heart failure) and injuries, poisoning, fractures and falls, and gastrointestinal diseases.

CONCLUSION

Most of the most common reasons for hospitalization are ambulatory care-sensitive hospital cases. Strengthening outpatient care for people with dementia may help prevent hospitalizations.

A nomogram for predicting risk of death during hospitalization in elderly patients with Alzheimer's disease at the time of admission

Background and objectives

Elderly patients with Alzheimer's disease (AD) often have multiple underlying disorders that lead to frequent hospital admissions and are associated with adverse outcomes such as in-hospital mortality. The aim of our study was to develop a nomogram to be used at hospital admission for predicting the risk of death in patients with AD during hospitalization.

Methods

We established a prediction model based on a dataset of 328 patients hospitalized with AD -who were admitted and discharged from January 2015 to December 2020. A multivariate logistic regression analysis method combined with a minimum absolute contraction and selection operator regression model was used to establish the prediction model. The identification, calibration, and clinical usefulness of the predictive model were evaluated using the C-index, calibration diagram, and decision curve analysis. Internal validation was evaluated using bootstrapping.

Results

The independent risk factors included in our nomogram were diabetes, coronary heart disease (CHD), heart failure, hypotension, chronic obstructive pulmonary disease (COPD), cerebral infarction, chronic kidney disease (CKD), anemia, activities of daily living (ADL) and systolic blood pressure (SBP). The C-index and AUC of the model were both 0.954 (95% CI: 0.929-0.978), suggesting that the model had accurate discrimination ability and calibration. Internal validation achieved a good C-index of 0.940.

Conclusion

The nomogram including the comorbidities (i.e., diabetes, CHD, heart failure, hypotension, COPD, cerebral infarction, anemia and CKD), ADL and SBP can be conveniently used to facilitate individualized identification of risk of death during hospitalization in patients with AD.

Analyses of hospitalization in Alzheimer's disease and Parkinson's disease in a tertiary hospital

Background

To characterize the pattern of hospitalization in patients with Alzheimer's disease (AD) or Parkinson's disease (PD), and compare the differences to see whether AD patients and PD patients have a different picture of hospitalization.

Methods

The clinical features of all consecutive patients from January 2017 to December 2020 were reviewed. We identified AD patients and PD patients from an electronic database in a tertiary medical center.

Results

The study group comprised 995 AD patients and 2,298 PD patients who were admitted to the hospital for the first time, and re-hospitalized 231 AD patients and 371 PD patients were also included. AD patients were older than PD patients when they were hospitalized (p < 0.001). AD patients had longer lengths of stay, higher re-hospitalization rates, and higher intrahospital mortality rates than PD patients during hospitalization even after adjusting age and gender. PD patients had higher levels of total cost than AD patients due to the cost of the deep brain stimulation (DBS) insertion. Hospitalizations for AD patients occurred most often in the department of geriatrics, while most PD patients were admitted to the department of neurology. Hospitalization due to the presence of comorbid conditions was much higher in AD patients, but a larger proportion of PD patients were hospitalized due to PD disease itself.

Conclusions

The present study found that AD patients and PD patients have a significantly different picture of hospitalization. It is important to implement different management for hospitalized AD and PD, and different emphasis should be given when establishing primary prevention strategies, informing care needs, and guiding healthcare resource planning.

What is the impact of ongoing statin use on cognitive decline and dementia progression in older adults with mild-moderate Alzheimer disease?

BACKGROUND

In addition to the clear cardiovascular benefit, there has been renewed interest in the potential of statins in the prevention of cognitive impairment and dementia in older adults. However, whether ongoing statin use can delay cognitive decline or dementia progression in those with established Alzheimer dementia, is unclear.

METHODS

Using data from NILVAD, we analysed the association between ongoing statin use and cognitive decline (Alzheimer Disease Assessment Scale-Cognitive Subsection [ADAS-Cog])/dementia progression (Clinical Dementia Rating Scale [CDR-Sb]/Disability Assessment for Dementia [DAD]) over 18 months in older adults with mild-moderate AD. Additionally, we assessed the association between ongoing statin use and adverse events in mild-moderate AD.

RESULTS

Over one-third (34.9%) of 510 older adults with mild-moderate AD (aged: 72.9 years; 61.9% female) used a statin for the 18-month study duration. Statin use was not associated with the rate of cognitive decline (β: -0.67; 95% CI: -1.71, 0.36, p = 0.20) or dementia progression (β: -0.34; 95% CI -0.71, 0.02; p = 0.07 for CDR-Sb/ β: -2.00; -5.70, 1.70; p = 0.29 for DAD). Further, ongoing statin use was not associated with adverse events, serious adverse events, unscheduled GP visits, or unscheduled hospitalisation.

CONCLUSION

Ongoing statin use was not associated with cognitive decline or dementia progression in mild-moderate AD. Similarly, use was not associated with adverse events including abnormal liver function tests or falls. Whilst safe in those with AD, the current results suggest ongoing statin use does not delay cognitive decline or clinical progression in established AD.

Dementia and Related Comorbidity: Analysis of 2 Years of Admissions to Italian Hospitals

BACKGROUND

The aim of the present study was to examine the prevalence of dementia, related comorbidities, and mortality rates in hospitalized elderly patients in Italy.

METHODS

Data were obtained from the Italian Ministry of Health and included all discharge records from Italian hospitals concerning subjects aged 65 years or above admitted to acute Internal Medicine during 2 years (n=3,695,278 admissions). Discharge diagnoses were re-classified into 24 clusters, each including homogeneous diseases by the ICD-9-CM code classification. Dementia was identified by the presence of ICD-9-CM codes 290, 294, or 331 series.

RESULTS

Patients with dementia represented 7.5% of the sample; compared with those without dementia, they were older and more often female, had a greater length of hospital stay and higher mortality rate. Besides delirium [odds ratio (OR): 54.20], enthesopaties (OR: 2.19), diseases of fluids and electrolytes (OR:1.96), diseases of arteries (OR: 1.69), skin diseases (OR: 1.64), and pneumonia and pleurisy (OR: 1.53) were the diseases more strongly associated with the diagnosis of dementia, independent of other clusters, age, sex, and length of stay.

CONCLUSIONS

Some comorbidities are specifically associated with the diagnosis of dementia among hospitalized elderly patients. Overall, these comorbidities describe the typical clinical profile of the patient with advanced dementia and could be treated in the context of the primary care, since they do not require specific skills belonging to hospital settings.

Risk factors for in-hospital death in elderly patients over 65 years of age with dementia: A retrospective cross-sectional study

As the population continues to age, dementia is becoming a huge social, economic, and healthcare burden. However, the risk factors for in-hospital death in elderly patients over 65 years of age with dementia are not well understood. Identifying factors that affect their prognosis could help clinicians with scientific decision-making. To examine the risk factors for in-hospital death in elderly patients over 65 years of age with dementia in the Geriatric Department of West China Hospital. In this retrospective, cross-sectional study, we analyzed inpatients aged ≥65 years with dementia between 2010 and 2016 using electronic medical records from the Information Center of West China Hospital. The risk factors for death were assessed using multivariable logistic regression. Out of a total of 2986 inpatients with dementia, 3.4% died. Patient deaths were related to digestive diseases, respiratory diseases, circulatory diseases, urinary diseases, and chronic obstructive pulmonary disease, whereas patient survival was associated with osteoporosis and Parkinson disease. Patients with a mean length of hospital stay of ≥60 days had an increased risk of death (all P <.05). In the multiple logistic regression analysis, age ≥80 years, digestive diseases, respiratory diseases, urinary diseases, diabetes, chronic obstructive pulmonary disease, and ≥7 comorbidities were risk factors for death. Mortality in hospitalized older patients with dementia is low, but some risk factors may be easily ignored. These findings could raise awareness among clinicians and caregivers about risk factors in hospitalized older patients, particularly hospitalized elderly patients with multiple comorbidities. Therefore, to reduce mortality, early prevention and management of potential risks are necessary.

Dementia and in-hospital mortality: retrospective analysis of a nationwide administrative database of elderly subjects in Italy

AIMS

 To evaluate the relationship between comorbidity and in-hospital mortality in elderly patients affected by dementia.

METHODS

Data were obtained from the Italian Ministry of Health and included all discharge records from Italian hospitals concerning subjects aged ≥ 65 years admitted to acute Internal Medicine or Geriatrics wards between January 2015 and December 2016 (3.695.278 admissions). The variables analyzed included age, sex, and in-hospital death. Twenty-five homogeneous clusters of diseases were identified in discharge codes according to the ICD-9-CM classification.

RESULTS

Patients with dementia represented 7.5% of the sample (n. 278.149); they were older, more often males (51.9%), and had a higher in-hospital mortality (24.3%) compared to patients without dementia (9.7%). Dementia per se doubled the odds of death (OR 1.98; 95% CI 1.95-2.00), independent of age, sex, and comorbidities. Seven clusters of disease (pneumonia, heart failure, kidneys disease, cancer, infectious diseases, diseases of fluids/electrolytes and general symptoms) were associated with increased in-hospital mortality, independent of the presence/absence of dementia. Among patients with dementia, heart failure, pneumonia and kidney disease on their own substantially doubled/tripled mortality risk. The risk increased from 10.1% (none of selected conditions), up to 28.9% when only one of selected comorbidities was present, rising to 52.3% (OR: 9.34; p < 0.001) when two or more comorbidities were simultaneously diagnosed, besides general symptoms.

CONCLUSIONS

Our study confirmed an important increase of in-hospital mortality in older subjects with dementia. Despite a different comorbidity, the conditions associated with in-hospital mortality were substantially the same in patients with or without dementia. Heart failure, pneumonia, and kidney disease identified a high risk of in-hospital mortality among subjects with dementia.

The co-occurrence of dementia in those with epilepsy is associated with 30-day readmission - A population-based study

OBJECTIVE

Dementia and epilepsy often co-occur and are associated with poor health outcomes and increased healthcare utilization. The literature on the association between readmission and co-occurrence of dementia and epilepsy is scant. Our objective was to determine if dementia in patients with epilepsy >40 years old is associated with 30-day hospital readmission, in-hospital mortality, discharge disposition, and length-of-stay.

METHODS

This retrospective cohort study used the 2014 Nationwide Readmissions Database, containing data from hospital discharges across the US and readmissions. Epilepsy and dementia were identified using previously validated ICD-9-CM codes. Primary outcome was 30-day readmission, analyzed with univariable and multivariable logistic regressions. Secondary outcomes were discharge disposition, in-hospital mortality, and length-of-stay, analyzed with univariable multinomial logistic, univariable logistic, and univariable ordinary least squared regressions, respectively. The top ten causes of readmission in each group were compared as well. All analyses accounted for survey weights, cluster, and stratum.

RESULTS

Patients with epilepsy with dementia (n = 15,588) had longer hospital stays [15% (95%CI 10-20%)], and higher odds of readmission [OR 1.11 (95%CI 1.05-1.17)], transfer to another facility [OR 2.18 (95%CI 1.93-2.46)], and in-hospital mortality [OR 1.50 (95%CI 1.25-1.79)] compared to those without dementia (n = 186,289).The top two causes of readmission were septicemia (dementia: 14.81%; no dementia: 9.45%) and epilepsy/convulsions (dementia: 5.91%; no dementia: 6.25%). Other top 10 causes of readmissions in those with epilepsy and dementia which were not present in those without dementia included delirium (5.21%), urinary tract infections (4.98%), and aspiration pneumonitis (4.29%).

SIGNIFICANCE

Dementia in epilepsy is associated with worse outcomes, including higher in-hospital mortality and higher readmissions. Potentially preventable causes of readmission in those with epilepsy and dementia were identified, including septicemia, delirium, urinary tract infection, and aspiration pneumonitis. Future studies are needed to inform interventions aimed at decreasing premature mortality and reducing potentially preventable readmissions in this vulnerable population.

Factors influencing length of hospital stay in an acute psychogeriatric unit

BACKGROUND

Dementia patients represent a significant volume of hospital admissions and impose a high cost on the health system. There is a significantly higher length of hospital stay (LOHS) for elderly demented patients.

METHODS

This study was carried out in an acute psychogeriatric unit specialising in behavioural and psychological symptoms in dementia. Socio-demographic, cognitive and nutritional variables were taken into account. We first compared the patients returning home (group 1) after hospital discharge with those transferred to the rehabilitation psychogeriatric unit (group 2). We secondarily explored the correlation of LOHS with the variables described above for the two groups.

RESULTS

We retained 92 patients (of 375 admitted) for our study, mean age 83.9 ± 6.6, Mini-Mental State Examination 12.8 ± 9.6, initial weight 61.7 ± 13.2 kg and body mass index 24.8 ± 4.7. We noticed significant differences in cognitive status but not in nutritional variables or in socio-demographic characteristics between the two groups. Only weight in nutritional variables was significantly associated with LOHS in the acute psychogeriatric unit.

CONCLUSIONS

Our main finding underlined the key role of cognitive factors in patient discharge home. And only initial weigh seems have an influence in LOHS instead of cognitive status or socio-demographic characteristics.

Cognitive Impairment and Length of Stay in Acute Care Hospitals: A Scoping Review of the Literature

Older persons experiencing a longer length of stay (LOS) or delayed discharge (DD) may see a decline in their health and well-being, generating significant costs. This review aimed to identify evidence on the impact of cognitive impairment (CI) on acute care hospital LOS/DD. A scoping review of studies examining the association between CI and LOS/DD was performed. We searched six databases; two reviewers independently screened references until November 2019. A narrative synthesis was used to answer the research question; 58 studies were included of which 33 found a positive association between CI and LOS or DD, 8 studies had mixed results, 3 found an inverse relationship, and 14 showed an indirect link between CI-related syndromes and LOS/DD. Thus, cognitive impairment seemed to be frequently associated with increased LOS/DD. Future research should consider CI together with other risks for LOS/DD and also focus on explaining the association between the two.

Dementia identified as a risk factor for infection-related hospital contacts in a national, population-based and longitudinal matched-cohort study

The aim of this study was to investigate the association between incident dementia and rates of infection-related hospital contacts. We conducted a registry- and population-based matched-cohort study of all Danish residents who were born in or before 1950, included from 1 January 2000 or their 65th birthday (whichever came later), who were alive and resided in Denmark at the start of the study, excluding those who had received a dementia diagnosis before 1 January 2000 or their 65th birthday (n = 1,712,100). A total of 129,660 people (403,744 person years) with incident dementia were matched with 297,476 people (1,918,784 person years) without dementia. Incidence rate ratios (IRRs) of infection-related hospital contacts were calculated using Poisson regression, by infection type, sex and age. The IRR for any infection-related contact in dementia was 1.5, was highest for nervous and urinary system infections and sepsis, decreased with increasing age and was higher in men. More people with than without dementia had contacts five years before the index date. Our findings show that dementia is a risk factor for infection-related hospital contacts and infections might be an early sign of dementia.

Length of hospital stay among oldest-old patients in acute geriatric ward

PURPOSE

To examine risk factors for prolonged hospital length of stay (LOS) in the oldest-old inpatients aged ≥ 90.

METHODS

This retrospective cross-sectional study was performed in acute Geriatrics Department at Kaplan Medical Center. The target population was the oldest-old inpatients aged ≥ 90 hospitalized with acute illness. In total 1536 admissions of 987 patients admitted between January 2007 and December 2010 from the emergency room were included in the study. We retrieved from the electronic hospital records the following data: demographics, admission diagnosis, comorbidities, laboratory tests, drugs, functional and cognitive status, Charlson Comorbidity Index (CCI) score and age-adjusted CCI score.

RESULTS

The risk factors for a prolonged LOS were tube-feeding, consumption of ≥ 5 drugs, non-independent functional status, diagnosis of urinary tract infection (UTI), pneumonia and malignancy on admission, and comorbidities of congestive heart failure (CHF) and hypoalbuminemia. Multiple linear regression analysis found that UTI, hypoalbuminemia, elevated troponin, pneumonia, number of drugs, malignancy, CHF and number of comorbidities explain a higher risk for a longer LOS.

CONCLUSION

Hospital LOS in the oldest-old patients in acute geriatric ward was associated with admission diagnosis and comorbidities. Awareness of the risk factors for a longer LOS might contribute to reducing hospitalization stay and its related negative consequences. Accurate prediction of prolonged LOS in this age group of patients may be more challenging and require variables that were not included in our study. Future research is warranted.

Can Continuity of Care Reduce Hospitalization Among Community-dwelling Older Adult Veterans Living With Dementia?

BACKGROUND

Hospitalization is a difficult experience, especially for patients with dementia. Understanding whether better continuity of care (COC) reduces hospitalizations can indicate interventions that might help curb hospitalizations.

OBJECTIVE

To estimate the causal impact of COC on hospitalizations and different reasons for hospitalization among community-dwelling older veterans with dementia.

RESEARCH DESIGN

Population-based observational study using nationwide Veterans Health Administration data linked to Medicare claims in Fiscal Years (FYs) 2014-2015. To account for unobserved confounders we used an instrumental variable for COC-whether veteran changed residence by more than 10 miles.

SUBJECTS

Community-dwelling veterans with dementia aged 66 and older, enrolled in Traditional Medicare (n=105,528).

MEASURES

Bice-Boxerman Continuity of Care (BBC) index (0-worst to 1-best COC); binary indicators of any hospitalization for all causes, for ambulatory care sensitive conditions (ACSCs) and for reasons grouped by major diagnostic category.

RESULTS

The mean BBC in FY 2014 was 0.32 (SD, 0.23). In FY 2015 43.3% of the cohort veterans were hospitalized. A 0.1 higher BBC resulted in 2.4% (95% confidence interval, 0.5%-4.4%) lower probability of hospitalization for all causes. BBC was not associated with hospitalization for ACSCs. Grouped by major diagnostic category, a 0.1 higher BBC resulted in 3.8% (95% confidence interval, 2.1%-5.4%) lower probability of hospitalization for neuropsychiatric diseases/disorders, with no impact on hospitalizations for circulatory, respiratory, infectious, kidney and urinary, digestive, musculoskeletal, and endocrine-metabolic diseases/disorders.

CONCLUSIONS

Among community-dwelling older veterans with dementia, better COC resulted in less hospitalizations, and this effect was primarily due to less hospitalization for neuropsychiatric diseases/disorders but not hospitalization for ACSCs, or other hospitalization reasons.

Hospitalization and Socio-Health Care for Dementia in Spain

Dementias are brain diseases that affect long-term cognitive and behavioral functions and cause a decrease in the ability to think and remember that is severe enough to disturb daily functioning. In Spain, the number of people suffering from dementia is rising due to population ageing. Reducing admissions, many of them avoidable, would be advantageous for patients and care-providers. Understanding the correlation of admission of people with dementia and its trends in hospitalization would help us to understand the factors leading to admission. We conducted a cross-sectional study of the hospital discharge database of Castilla y León from 2005 to 2015, selecting hospitalizations for dementia. Trends in hospitalizations by year and age quartiles were studied by joinpoint regression analysis. 2807 out of 2,717,192 total hospitalizations (0.10%) were due to dementias; the main groups were degenerative dementia (1907) followed by vascular dementia (607). Dementias are not a major cause of hospitalization, but the average stay and cost are high, and many of them seem avoidable. Decreasing trends were detected in hospitalization rates for all dementias except for the group of mild cognitive impairment, which grew. An increasing–decreasing joinpoint detected in 2007 for vascular dementia and the general downward hospitalization trends for most dementias suggest that socio-health measures established since 2007 in Spain might play a key role in reducing hospitalizations.

Diagnosis of Rapidly Progressive Dementia in a Referral Center in Argentina

INTRODUCTION

Rapidly progressive dementia (RPD) is a broadly defined clinical syndrome. Our aim was to describe clinical and ancillary study findings in patients with RPD and evaluate their diagnostic performance for the identification of nonchronic neurodegenerative rapidly progressive dementia (ncnRPD).

METHODS

We reviewed clinical records and ancillary methods of patients evaluated for RPD at our institution in Buenos Aires, Argentina from 2011 to 2017. We compared findings between chronic neurodegenerative RPD and ncnRPD and evaluated the diagnostic metrics using receiver operating characteristic curves.

RESULTS

We included 104 patients with RPD, 29 of whom were chronic neurodegenerative RPD and 75 of whom were ncnRPD. The 6-month time to dementia cutpoint had a sensitivity of 89% and specificity of 100% for ncnRPD, with an area under the receiver operating characteristic curve of 0.965 (95% confidence interval=0.935-0.99; P<0.001). A decision tree that included time to dementia, brain magnetic resonance imaging, and cerebrospinal fluid analysis identified ncnRPD patients with a sensitivity of 100%, specificity of 79%, positive predictive value of 93%, and negative predictive value of 100% overall.

DISCUSSION

RPD is a clinical syndrome that comprises different diagnoses, many of them for treatable diseases. Using the time to dementia, brain magnetic resonance imaging, and cerebrospinal fluid analysis when triaging these patients could help identify those diseases that need to be studied more aggressively.

Drug related problems in older adults living with dementia

BACKGROUND

Compared with those without dementia, older patients with dementia admitted to acute care settings are at higher risk for triad combination of polypharmacy (PP), potentially inappropriate medication (PIM), and drug-drug interaction (DDI), which may consequently result in detrimental health. The aims of this research were to assess risk factors associated with triad combination of PP, PIM and DDI among hospitalized older patients with dementia, and to assess prevalence and characteristics of PP, PIM and DDI in this population.

METHODS

In this retrospective cross-sectional study, 416 older inpatients diagnosed with dementia and referred for specialist geriatric consultation at a tertiary hospital in Brisbane, Australia during 2006-2016 were enrolled. Patients were categorized into two groups according to their exposure to the combination of PP, PIM and DDI: 'triad combination' and 'non-triad combination'. Data were collected using the interRAI Acute Care (AC) assessment instrument. Independent risk factors of exposure to the triad combination were evaluated using bivariate and multivariate logistic regression analyses.

RESULTS

Overall, 181 (43.5%) were classified as triad combination group. The majority of the population took at least 1 PIM (56%) or experienced at least one potential DDI (76%). Over 75% of the participants were exposed to polypharmacy. The most common prescribed PIMs were antipsychotics, followed by benzodiazepines. The independent risk factors of the triad combination were the presence of atrial fibrillation diagnosis and higher medications use in cardiac therapy, psycholeptics and psychoanaleptics.

CONCLUSIONS

The exposure to triad combination of PP, PIM and DDI are common among people with dementia as a result of their vulnerable conditions and the greater risks of adverse events from medications use. This study identified the use of cardiac therapy, psycholeptics and psychoanaleptics as predictors of exposure to PP, PIM and DDI. Therefore, use of these medications should be carefully considered and closely monitored. Furthermore, comprehensive medication reviews to optimize medication prescribing should be initiated and continually implemented for this vulnerable population.

Changing needs in advanced dementia

This is the first article in a six-part series in Nursing Older People exploring the nursing care of people living with advanced dementia. This article discusses the changes that may occur as dementia progresses, from the perspective of the individual, their family and other carers. A person living with advanced dementia is likely to experience physical, cognitive and social changes that can be profound and debilitating. Healthcare needs intensify as new and co-existing issues result in increasing dependency on others for support with activities of daily living. These activities can include eating, drinking, mobility and personal care. Consequently, family carers may find their role has to develop and change to provide increasing support in response to these complex needs. These increasing needs can result in care transitions to hospitals or care homes. Careful and collaborative management of care is crucial to maintain quality of life for the person with dementia and family carers.

The association between dementia severity and hospitalisation profile in a newly assessed clinical cohort: the South London and Maudsley case register

OBJECTIVES

To evaluate the risk and common causes of hospitalisation in patients with newly diagnosed dementia and variation by severity of cognitive impairment.

SETTING

We used data from a large London mental healthcare case register linked to a national hospitalisation database.

PARTICIPANTS

Individuals aged ≥65 years with newly diagnosed dementia with recorded cognitive function and the catchment population within the same geography.

OUTCOME MEASURES

We evaluated the risk and duration of hospitalisation in the year following a dementia diagnosis. In addition we identified the most common causes of hospitalisation and calculated age-standardised and gender-standardised admission ratios by dementia severity (mild/moderate/severe) relative to the catchment population.

RESULTS

Of the 5218 patients with dementia, 2596 (49.8%) were hospitalised in the year following diagnosis. The proportion of individuals with mild, moderate and severe dementia who had a hospital admission was 47.9%, 50.8% and 51.7%, respectively (p= 0.097). Duration of hospital stay increased with dementia severity (median 2 days in mild to 4 days in severe dementia, p 0.0001). After excluding readmissions for the same cause, the most common primary hospitalisation discharge diagnoses among patients with dementia were urinary system disorders, pneumonia and fracture of femur, accounting for 15%, 10% and 6% of admissions, respectively. Overall, patients with dementia were hospitalised 30% more than the catchment population, and this trend was observed for most of the discharge diagnoses evaluated. Standardised admission ratios for urinary and respiratory disorders were higher in those with more severe dementia at diagnosis.

CONCLUSIONS

Individuals with a dementia diagnosis were more likely to be hospitalised than individuals in the catchment population. The length of hospital stay increased with dementia severity. Most of the common causes of hospitalisation were more common than expected relative to the catchment population, but standardised admission ratios only varied by dementia stage for certain groups of conditions.

Health outcomes of patients with dementia in acute care settings-A systematic review

BACKGROUND

An ageing population has resulted in increased numbers of people with dementia attending acute care services; however, the impact of hospitalisation on this population is uncertain.

PURPOSE

This systematic review aimed to synthesise the available evidence on adverse health outcomes for people with dementia in acute care settings.

METHODS

A systematic search of CINAHL, PubMed, MEDLINE, EMBASE and Scopus databases for primary research articles in English language, published from 2000 to 2017, was conducted. A protocol for the review was registered on the PROSPERO database.

RESULTS

The initial search identified 5,520 records. Following removal of duplicates and assessment against inclusion criteria, 13 studies were included in the final review. Findings identify associations between patients with dementia, longer length of hospital stay and higher mortality in some situations. Heterogeneity across studies in data reporting and outcomes prevented meta-analysis; therefore, results are presented narratively.

CONCLUSIONS

Certainty of findings from this review is impacted by variation in patient condition and data reporting. Additional rigorous studies on health outcomes for people with dementia during acute hospitalisation will contribute to the evidence.

IMPLICATIONS FOR PRACTICE

These findings along with further research examining outcomes for patients with dementia in acute care settings will inform provision of safer, quality care and optimal health outcomes for this vulnerable population.

Primary diagnoses and outcomes of emergency department visits in older people with dementia: a hospital-based retrospective study in Taiwan

OBJECTIVES

The objectives of this study were to investigate the primary diagnoses and outcomes of emergency department visits in older people with dementia and to compare these parameters with those in older adults without dementia.

DESIGN AND SETTING

This hospital-based retrospective study retrieved patient records from a hospital research database, which included the outpatient and inpatient claims of two hospitals.

PARTICIPANTS

The patient records were retrieved from the two hospitals in an urban setting. The inclusion criteria were all patients aged 65 and older who had attended the two hospitals as an outpatient or inpatient between January 1, 2009, and December 31, 2016. Patients with dementia were identified to have at least three reports of diagnostic codes, either during outpatient visits, during emergency department visits, or in hospitalized database records. The other patients were categorized as patients without dementia.

MEASUREMENTS

The primary diagnosis during the emergency department visit, cost of emergency department treatment, cost of hospital admission, length of hospital stay, and diagnosis of death were collected.

RESULTS

A total of 149,203 outpatients and inpatients aged 65 and older who were admitted to the two hospitals were retrieved. The rate of emergency department visits in patients with dementia (23.2%) was lower than that in those without dementia (48.6%). The most frequent primary reason for emergency department visits and the main cause of patient death was pneumonia. Patients with dementia in the emergency department had higher hospital admission rates and longer hospital stays; however, the cost of treatment did not show a significant difference between the two groups.

CONCLUSIONS

Future large and prospective studies should explore the severity of disease in older people with dementia and compare results with older adults without dementia in the emergency department.

["Memory acute"-treatment concept for inpatient remobilization of acutely ill patients with dementia]

BACKGROUND

Acute hospitals are generally not designed for people with dementia. Behavioral issues pose the greatest challenge. This article reports on the results of a prospective controlled study designed to assess whether dementia patients benefit from a remobilization strategy in a memory clinic (IG-MA) following hospital discharge.

METHODS

Between January and September 2018 patients with moderate to severe dementia discharged from hospital following acute episodes were admitted to an IG-MA for remobilization. The IG-MA unit provides specially qualified personnel and an adapted environment. Control groups were formed from the standard remobilization unit (KG1-AGR) and four care homes (KG2-PWH).

RESULTS

Patients in the IG-MA (n = 22) had a worse functional status at admission according to the Barthel index (BI), the timed "up and go" test (TUG) and the Esslinger transfer scale (ETS) than patients in the KG1-AGR (n = 59). Outcomes significantly improved in both groups (IG-MA and KG1-AGR) without a clear difference between groups: IG-MA (BI from 35 to 57.8 points, TUG from 30.8 s to 23 s, ETS from 2.1 to 1.1 points) vs. KG1-AGR (BI from 44.7 to 62.4 points, TUG from 28.6 s to 20.2 s, ETS from 1.7 to 0.9 points). There were differences in cognitive ability at admission (mini mental state examination, MMSE: IG-MA 13.6 points vs. KG1-AGR 20 points). The length of stay in the IG-MA was on average 5 days longer. Early discharge was mostly the result of complications and transfer to acute hospitals in the IG-MA group (22.7%) and in the KG1-AGR group this was mostly due to care issues (27.1%). The KG2-PWH group did not show any significant functional improvements in the first 4 weeks as measured by the BI.

CONCLUSION

Moderate to severely affected dementia patients with behavioral problems benefited from treatment in a specially designed remobilization unit following hospital discharge after an acute event.

Can non-pharmacological interventions reduce hospital admissions in people with dementia? A systematic review

Background

People with dementia who are admitted to hospital have worse outcomes than those without dementia. Identifying interventions that could reduce the risk of hospitalisation in people with dementia has the potential to positively impact on lives of people with dementia. This review aimed to investigate whether there are non-pharmacological interventions that successfully reduce hospitalisation risk, length of stay and mortality in people with dementia.

Methods

7 electronic databases and trial registries were searched from inception to October 2018. We included randomised controlled trials that evaluated non-pharmacological interventions in out of hospital settings and targeted people with any type of dementia. All stages of the review process were performed by two reviewers. Risk of bias was assessed using the Cochrane Risk of Bias tool. We grouped studies based on intervention: care management, counselling/self-help, enhanced GP services or memory clinics, and physiotherapy or occupational therapy. Data were pooled within intervention categories using random effects meta-analysis.

Results

There was no evidence that any of the intervention categories were associated with reduced hospital admission or mortality. There was very weak evidence to suggest that care management interventions (mean difference, MD, -0.16, 95% CI -0.32, 0.01), physiotherapy/occupational therapy (MD -0.16, 95% CI -0.36, 0.03) and enhanced GP/memory clinics (MD -0.14, 95% CI -0.31, 0.03) were associated with small reductions in hospital stay. There was no evidence for an effect of counselling/self-help interventions on length of hospital stay.

Conclusions

Current evidence from randomised trials suggests no clear benefit or harm associated with any of interventions on risks of hospitalisation, duration of hospitalisation or death. Further research with the primary aim to reduce hospitalisation in people with dementia is required.

Risk factors for in-hospital mortality in patients with dementia

OBJECTIVE

To examine the in-hospital mortality rate, and its risk factors, for patients with dementia admitted to hospital.

STUDY DESIGN

We constructed an observational cohort study through data linkage of three Dutch national registers: the hospital discharge register (HDR), the population register (PR) and the national cause of death register. Patients with dementia in the HDR aged between 60 and 100 years registered between 1 January 2000 and 31 December 2010 were included.

MAIN OUTCOME MEASURES

Risk factors for in-hospital mortality were investigated using multivariable Cox proportional hazard regression models that included sex, age, marital status, ethnicity, somatic comorbidity, type of dementia and urgency of admission.

RESULTS

40,500 patients were included in the cohort. The overall in-hospital mortality rate was 11.1%. Factors that significantly increased the mortality risk were: male sex (adjusted hazard ratio (HR) 1.52, 95%-confidence interval (95%-CI) 1.43-1.63), higher age (adjusted HR 1.03, 95%-CI 1.03-1.04), living with a partner (adjusted HR 1.39, 95%-CI 1.30-1.49), acute admission (adjusted HR 2.16, 95%-CI 1.97-2.36) and Alzheimer's disease (adjusted HR 1.21, 95%-CI 1.13-1.29). Cardiovascular disease was the most common cause of in-hospital mortality.

CONCLUSIONS

This nationwide study found several independent risk factors for the in-hospital mortality of patients with dementia, including male sex, higher age, living with a partner, acute admission, and Alzheimer's disease. These risk factors should be taken into account by clinicians and caregivers as they will indicate whether patients are at risk of a more unfavourable outcome during hospital admission.

Hospitalization after Oral Antibiotic Initiation in Finnish Community Dwellers with and without Alzheimer's Disease: Retrospective Register-Based Cohort Study

BACKGROUND

Persons with Alzheimer's disease (AD) are frequently hospitalized from infection-related causes. There are no previous studies investigating hospitalization associated with antibiotic initiation in persons with AD.

OBJECTIVE

To investigate the frequency and risk of hospitalization associated with oral antibiotic initiation among community dwellers with and without AD.

METHODS

We performed a retrospective register-based study utilizing register-based Medication Use and Alzheimer's disease (MEDALZ) cohort. It includes all community dwellers diagnosed with AD during 2005-2011 in Finland and their matched comparison persons without AD. Antibiotic use was initiated by 34,785 persons with and 36,428 without AD. Drug use data were collected from Prescription Register and comorbidities from Special Reimbursement and Hospital Care Registers. Infection diagnoses were collected from the Hospital Care Register. Factors associated with hospitalization were estimated utilizing logistic regression models.

RESULTS

Risk of hospitalization following antibiotic initiation was higher among antibiotic initiators with AD than without AD (adjusted odds ratio, aOR, 1.37, 95% Cl 1.28-1.46).Strongest association with hospitalization was found for oral glucocorticoid use, aOR 1.41 (1.25-1.59); epilepsy, aOR 1.33 (1.10-1.63); and active cancer, aOR 1.30 (1.14-1.49). Among initiators of cephalexin, pivmecillinam, amoxicillin/amoxicillin, and enzyme inhibitor and doxycycline, persons with AD were more frequently hospitalized than persons without AD. A quarter of hospitalized antibiotic initiators had infection diagnosis in their hospital care records.

CONCLUSIONS

Persons with AD initiating an antibiotic had a higher risk for hospitalization than antibiotic initiators without AD. Further research is needed to determine whether infection-related hospitalization could be reduced.

Dementia in elderly patients undergoing early cholecystectomy for acute cholecystitis: a retrospective observational study

Background

Dementia often adversely affects postoperative outcomes in surgical patients. This study evaluated postoperative outcomes among elderly patients with and without dementia undergoing early cholecystectomy for acute cholecystitis (AC).

Methods

A total of 182 patients over 85 years of age who were diagnosed with AC and treated from January 2005 to March 2018 were reviewed retrospectively; 59 patients who underwent early cholecystectomy were enrolled. The complication rates, length of postoperative hospital stay, and rates of routine discharge (i.e., returning to their preoperative living location) were compared between two groups of patients with and without dementia.

Results

The overall complication rate after early cholecystectomy for AC in 59 patients was 11.9%, and there was no mortality in this series. The median postoperative hospital stay was 9.0 days, and the routine discharge rate was 89.8%. Of the 59 patients, 22 patients (37.3%) had a history of dementia. Complication rates were comparable between the groups, despite the rate of delirium development being significantly higher in the dementia group. The median length of postoperative hospital stay and routine discharge rates did not significantly differ between groups.

Conclusions

Early cholecystectomy for patients with AC over 85 years of age was performed safely, and elderly patients with dementia had similar postoperative outcomes as compared with patients without dementia.

The impact of dementia on hospital outcomes for elderly patients with sepsis: A population-based study

BACKGROUND

Prior studies have suggested that dementia adversely influences clinical outcomes and increases resource utilization in patients hospitalized for acute diseases. However, there is limited population-data information on the impact of dementia among elderly hospitalized patients with sepsis.

METHODS

From the 2009-2011 National Hospital Discharge Database we identified hospitalizations in adults aged ≥65 years. Using ICD9-CM codes, we selected sepsis cases, divided them into two cohorts (with and without dementia) and compared both groups with respect to organ dysfunction, in-hospital mortality and the use of hospital resources. We estimated the impact of dementia on these primary endpoints through multivariate regression models.

RESULTS

Of the 148 293 episodes of sepsis identified, 16 829 (11.3%) had diagnoses of dementia. Compared to their dementia-free counterparts, they were more predominantly female and older, had a lower burden of comorbidities and were more frequently admitted due to a principal diagnosis of sepsis. The dementia cohort showed a lower risk of organ dysfunction (adjusted OR: 0.84, 95% Confidence Interval [CI]: 0.81, 0.87) but higher in-hospital mortality (adjusted OR: 1.32, 95% [CI]: 1.27, 1.37). The impact of dementia on mortality was higher in the cases of younger age, without comorbidities and without organ dysfunction. The cases with dementia also had a lower length of stay (-3.87 days, 95% [CI]: -4.21, -3.54) and lower mean hospital costs (-3040€, 95% [CI]: -3279, -2800).

CONCLUSIONS

This nationwide population-based study shows that dementia is present in a substantial proportion of adults ≥65s hospitalized with sepsis, and while the condition does seem to come with a lower risk of organ dysfunction, it exerts a negative influence on in-hospital mortality and acts as an independent mortality predictor. Furthermore, it is significantly associated with shorter length of stay and lower hospital costs.

Length of hospital stay and dementia: A systematic review of observational studies

OBJECTIVE

Hospitalizations of people with dementia (PWD) are often accompanied by complications or functional loss and can lead to adverse outcomes. Unsystematic findings suggest an influence of comorbidities on the extent of differences in the length of hospital stay (LOS). This systematic review aimed to identify and evaluate all studies reporting LOS in PWD as compared to PwoD in general hospitals.

METHODS

A systematic review of observational studies using PubMed and ISI Web of Knowledge. Inclusion criteria comprised original studies written in English or German, assessment of diagnosis of dementia, measurement of LOS, and comparison of people with and without dementia.

RESULTS

Fifty-two of 60 studies reported a longer hospitalization time for PWD compared to PwoD. The extent of the difference in LOS varied between and within countries as well as by type of primary morbidity (eg, injuries, cardiovascular diseases). The range of the LOS difference for studies without restriction to a primary morbidity was -2 to +22 days after matching or adjustment for a variable number and selection of potentially relevant covariates. For studies with injuries/fractures/medical procedures and infectious/vascular disease as the primary morbidity, the range was -2.9 to +12.4 and -11.2 to +21.8 days, respectively.

CONCLUSIONS

The majority of studies reported a longer hospitalization of PWD compared to PwoD. Length of hospital stay seems to be influenced by a variety of medical, social, organizational factors, including reasons for hospital admission, whose role should be explored in detail in further research.

Dementia in older people admitted to hospital: An analysis of length of stay and associated costs

OBJECTIVES

Patients with dementia in the acute setting are generally considered to impose higher costs on the health system compared to those without the disease largely due to longer length of stay (LOS). Many studies exploring the economic impact of the disease extrapolate estimates based on the costs of patients diagnosed using routinely collected hospital discharge data only. However, much dementia is undiagnosed, and therefore in limiting the analysis to this cohort, we believe that LOS and the associated costs of dementia may be overestimated. We examined LOS and associated costs in a cohort of patients specifically screened for dementia in the hospital setting.

METHODS

Using primary data collected from a prospective observational study of patients aged ≥70 years, we conducted a comparative analysis of LOS and associated hospital costs for patients with and without a diagnosis of dementia.

RESULTS

There was no significant difference in overall length of stay and total costs between those with (μ = 9.9 days, μ = € 8246) and without (μ = 8.25 days, μ = € 6855) dementia. Categorical data analysis of LOS and costs between the two groups provided mixed results.

CONCLUSIONS

The results challenge the basis for estimating the costs of dementia in the acute setting using LOS data from only those patients with a formal dementia diagnosis identified by routinely collected hospital discharge data. Accurate disease prevalence data, encompassing all stages of disease severity, are required to enable an estimation of the true costs of dementia in the acute setting based on LOS.

Trends in Hospital Morbidity From Alzheimer's Disease in the European Union, 2000 to 2014

BACKGROUND

Alzheimer's disease (AD) has become a concerning public health issue. We aimed to analyze the trends of hospital morbidity from AD in the European Union (EU) in the period 2000 to 2014.

METHODS

Data from hospital discharges of men and women over 50 years old hospitalized due to AD in the EU were extracted from Eurostat database. We tested for secular trends computing anual percent change, and identified significant changes in the linear slope of the trend.

RESULTS

Hospital morbidity from AD showed a 0.8% (95% confidence intervals -2.2 to 0.6) slight declining trend in the EU. In men and women, we recorded a -0.5% and -1.0% decrease in hospital morbidity rates, respectively. Several countries showed changing trends during the study period.

CONCLUSION

Alzheimer's disease hospital morbidity has slightly declined in the entire EU in the past years. Eastern European countries showed steadily increasing trends, whereas in western and Mediterranean countries the rates decreased or leveled off.

Clinical characteristics of patients with dementia in a local emergency clinic in Japan

AIM

The present study aimed to clarify the clinical characteristics of patients with dementia in an emergency clinic.

METHODS

We retrospectively examined patients with dementia who visited the emergency clinic at Kurashiki Heisei Hospital, Okayama, Japan. Among 16 764 patients who visited our emergency clinic in the 3 years from 2014 to 2017, we focused on 2574 (15.4%) patients with dementia.

RESULTS

The mean age of patients with dementia was 84.9 ± 0.1 years, which was much older than the age of the total emergency patients (58.1 ± 0.2 years). The hospitalization rate was 54.9% for patients with dementia, which was more than double that of patients without dementia (23.3%; P <0.01), and was higher than that (44.3%) of patients who were aged ≥75 years without dementia. Infection (42.4%) and falls (20.9%) were the most common causes for emergency visits and hospitalization in the present study. Hospitalized patients with dementia spent a longer time in hospital for stroke (64.0 ± 5.3 days) and falls (51.9 ± 2.1 days) than those with infection, epilepsy, syncope, loss of consciousness, other causes (all P <0.01) or dehydration (P ≤ 0.05).

CONCLUSIONS

Patients with dementia commonly attend our emergency clinic. These patients are older in age, have a higher hospitalization rate and have a longer hospitalization, especially due to stroke and falls, than patients without dementia. Geriatr Gerontol Int 2018; 18: 1383-1387.

Hospital outcomes of older people with cognitive impairment: An integrative review

OBJECTIVES

To summarise existing knowledge of outcomes of older hospital patients with cognitive impairment, including the type and frequency of outcomes reported, and the additional risk experienced by this patient group.

METHODS

Integrative literature review. Health care literature databases, reports, and policy documents on key websites were systematically searched. Papers describing the outcomes of older people with cognitive impairment during hospitalisation and at discharge were analysed and summarised using integrative methods.

RESULTS

One hundred four articles were included. A range of outcomes were identified, including those occurring during hospitalisation and at discharge. Older people with a dementia diagnosis were at higher risk from death in hospital, nursing home admission, long lengths of stay, as well as intermediate outcomes such as delirium, falls, dehydration, reduction in nutritional status, decline in physical and cognitive function, and new infections in hospital. Fewer studies examined the relationship of all-cause cognitive impairment with outcomes. Patient and carer experiences of hospital admission were often poor. Few studies collected data relating to hospital environment, eg, ward type or staffing levels, and acuity of illness was rarely described.

CONCLUSIONS

Older people with cognitive impairment have a higher risk of a variety of negative outcomes in hospital. Prevalent intermediate outcomes suggest that changes in care processes are required to ensure maintenance of fundamental care provision and greater attention to patient safety in this vulnerable group. More research is required to understand the most appropriate ways of doing this and how changes in these care processes are best implemented to improve hospital outcomes.

Hospital admissions 2000-2014: A retrospective analysis of 288 096 events in patients with dementia

INTRODUCTION

Dementia is a leading cause of disability worldwide. It is associated with an increased risk of hospitalization, imposing a significant burden on healthcare systems. The evidence on the long-term evolution of this issue and broadly on healthcare systems is currently limited. This study aims to describe the hospitalizations of people who received a diagnosis of dementia admitted to public general hospitals in a western European country with universal health coverage, over more than a decade.

METHODS

This retrospective observational study analyzed all inpatient episodes from 2000 to 2014 with a primary or secondary diagnosis of dementia using a national hospitalization database from mainland Portuguese public hospitals.

RESULTS

A total of 288 096 hospital admissions were registered. Hospitalization rates increased 4.7 times throughout the study period. Pneumonia and urinary tract infections were the most frequent main diagnoses, while dementia itself was the cause of admission in a minority (6.8%) of cases. Cerebrovascular disease, diabetes without chronic complications, and congestive heart failure were the most prevalent comorbidities; 5.9% of patients with dementia admitted to hospital underwent a surgical procedure, orthopedic surgeries being the most frequent. The median length of hospital stay was 8.0 days, and in-hospital mortality rate was 16.1%.

CONCLUSIONS

Dementia patients represent a significant amount of hospital admissions. Most leading causes of hospital admissions are preventable if timely diagnosed and could be effectively managed in the outpatient setting. These findings may be useful for healthcare resource planning and allocation. Further research should drive evidence-based reorganization of health care systems.

Frequency of dementia among elderly admitted to a Geriatrics Inpatients Sector of a Brazilian public hospital

Patients with dementia are commonly admitted to inpatient sectors. The aim of this study was to describe the frequency of dementia among elderly inpatients admitted to the Geriatrics Sector of a Brazilian Tertiary University Hospital, and to identify associations between dementia and clinical and sociodemographic factors.

METHODS

All patients admitted to the Geriatrics Sector of a public Brazilian university-hospital from March 1st 2014 to January 31st 2015 were assessed by geriatricians. The patients were divided into groups "with or without diagnosis of dementia". Univariate analysis was performed between these two groups using the Chi-Square Test, Student's t-test or the Mann-Whitney Test.

RESULTS

One hundred and three elderly inpatients, with a mean age of 82 (±7.9) years, were assessed. Overall, 74.7% had low educational level (<4 years), 66% used polypharmacy, 57.2% developed delirium during hospitalization and 59% were totally dependent for basic activities of daily living. The diagnosis of dementia was observed in 59 (57%) subjects.

CONCLUSION

The frequency of dementia was high among the elderly inpatients evaluated. The association between dementia and certain clinical conditions, such as incontinence, delirium and use of psychoactive drugs, was in line with the medical literature.

Report by the Spanish Foundation of the Brain on the social impact of Alzheimer disease and other types of dementia

INTRODUCTION

Knowledge of the socioeconomic impact of dementia-related disorders is essential for appropriate management of healthcare resources and for raising social awareness.

METHODS

We performed a literature review of the published evidence on the epidemiology, morbidity, mortality, associated disability and dependence, and economic impact of dementia and Alzheimer disease (AD) in Spain.

CONCLUSIONS

Most population studies of patients older than 65 report prevalence rates ranging from 4% to 9%. Prevalence of dementia and AD is higher in women for nearly every age group. AD is the most common cause of dementia (50%-70% of all cases). Dementia is associated with increased morbidity, mortality, disability, and dependence, and results in a considerable decrease in quality of life and survival. Around 80% of all patients with dementia are cared for by their families, which cover a mean of 87% of the total economic cost, resulting in considerable economic and health burden on caregivers and loss of quality of life. The economic impact of dementia is huge and difficult to evaluate due to the combination of direct and indirect costs. More comprehensive programmes should be developed and resources dedicated to research, prevention, early diagnosis, multidimensional treatment, and multidisciplinary management of these patients in order to reduce the health, social, and economic burden of dementia.

Antipsychotic prescription and mortality in hospitalized older persons

BACKGROUND

Recent scientific reports have shown that older persons treated with antipsychotics for dementia-related behavioural symptoms have increased mortality. However, the impact of these drugs prescribed during hospitalization has rarely been assessed. We aimed to investigate whether antipsychotics are associated with an increased risk of mortality during hospitalization and at 3-month follow-up in elderly inpatients.

METHODS

We analyzed data gathered during two waves (2010 and 2012) by the REPOSI (Registro Politerapie Società Italiana Medicina Interna). All new prescriptions of antipsychotic drugs during hospitalization, whether maintained or discontinued at discharge, were collected, and logistic regression models were used to analyze their association with in-hospital and 3-month mortality. Covariates were age, sex, the Short Blessed Test (SBT) score, and the Cumulative Illness Rating Scale.

RESULTS

Among 2703 patients included in the study, 135 (5%) received new prescriptions for antipsychotic drugs. The most frequently prescribed antipsychotic during hospitalization and eventually maintained at discharge was haloperidol (38% and 36% of cases, respectively). Patients newly prescribed with antipsychotics were older and had a higher Cumulative Illness Rating Scale comorbidity index both at admission and at discharge compared to those who did not receive a prescription. Of those prescribed antipsychotics, 71% had an SBT score ≥10 (indicative of dementia), 12% had an SBT score of 5-9 (indicative of questionable dementia); and 17% had an SBT score <5 (indicative of normal cognition). In-hospital mortality was slightly higher in patients prescribed antipsychotic drugs (14.3% vs 9.4%; P = 0.109), but in multivariate analysis only male sex, older age, and higher SBT scores were significantly related to mortality during hospitalization. At 3-month follow-up, only male sex, older age, and higher SBT scores were associated with mortality.

CONCLUSION

We found that the prescription of antipsychotic drugs during hospitalization was not associated with in-hospital or follow-up mortality. Short-term antipsychotic prescriptions (for acutely ill patients) may have a different effect than long-term, repeated prescriptions.

Association between dementia and discharge status in patients hospitalized with pneumonia

Background

Pneumonia is the most common cause of death in patients with dementia, but the outcomes of patients with dementia hospitalized with pneumonia are poorly understood. We sought to illuminate the association between dementia and in-hospital mortality and discharge status in patients hospitalized with pneumonia.

Methods

We used the Diagnosis Procedure Combination database, a national inpatient database in Japan, to identify retrospectively patients aged ≥60 years admitted to hospital with pneumonia during the study period of May 1, 2010 to March 31, 2014. We recorded their sex, age, body mass index, severity of pneumonia and comorbidities (including dementia). The outcomes were in-hospital mortality and discharge home. Multivariable Cox regression analysis was performed to analyze factors influencing discharge home.

Results

We identified 470,829 patients hospitalized with pneumonia; 45,031 were recorded as having dementia (9.6%). In-hospital mortality was 13.1% and 13.4% in patients with and without dementia, respectively (P = 0.63). The proportions of patients discharged home were 52.9% and 71.3% in patients with and without dementia, respectively (P < 0.001). The adjusted hazard ratio for discharge home for patients with dementia was 0.68 (95% confidence interval, 0.67–0.69; P < 0.001).

Conclusions

In-hospital mortality from pneumonia did not differ significantly between patients with and without dementia; however, those with dementia were less likely to be discharged home.

Validity and reliability of the Patient Centred Assessment Method for patient complexity and relationship with hospital length of stay: a prospective cohort study

OBJECTIVES

Several instruments for evaluating patient complexity have been developed from a biopsychosocial perspective. Although relationships between the results obtained by these instruments and the length of stay in hospital have been examined, many instruments are complicated and not easy to use. The Patient Centred Assessment Method (PCAM) is a candidate for practical use. This study aimed to test the validity and reliability of the PCAM and examine the correlations between length of hospital stay and PCAM scores in a regional secondary care hospital in Japan.

DESIGN

Prospective cohort study.

PARTICIPANTS AND SETTING

Two hundred and one patients admitted to Ouji Coop Hospital between July 2014 and September 2014.

MAIN PREDICTOR

PCAM total score in initial phase of hospital admission.

MAIN OUTCOME

Length of stay in hospital.

RESULTS

Among 201 patients (Female/Male=98/103) with mean (SD) age of 77.4±11.9 years, the mean PCAM score was 25±7.3 and mean (SD) length of stay in hospital (LOS) 34.1±40.9 days. Using exploratory factor analysis to examine construct validity, PCAM evidently has a two-factor structure, comprising medicine-oriented and patient-oriented complexity. The Spearman rank correlation coefficient for evaluating criterion-based validity between PCAM and INTERMED was 0.90. For reliability, Cronbach's alpha was 0.85. According to negative binomial regression analyses, PCAM scores are a statistically significant predictor (p<0.001) of LOS after adjusting for age, gender, Mini Nutritional Assessment Short-Form, Charlson Comorbidity Index, serum sodium concentration, total number of medications and whether public assistance was required. In another model, each factor in PCAM was independently correlated with length of stay in hospital after adjustment (medicine-oriented complexity: p=0.001, patient-oriented complexity: p=0.014).

CONCLUSION

PCAM is a reliable and valid measurement of patient complexity and PCAM scores have a significant correlation with hospital length of stay.

Acute hospital dementia care: results from a national audit

BACKGROUND

Admission to an acute hospital can be distressing and disorientating for a person with dementia, and is associated with decline in cognitive and functional ability. The objective of this audit was to assess the quality of dementia care in acute hospitals in the Republic of Ireland.

METHODS

Across all 35 acute public hospitals, data was collected on care from admission through discharge using a retrospective chart review (n = 660), hospital organisation interview with senior management (n = 35), and ward level organisation interview with ward managers (n = 76). Inclusion criteria included a diagnosis of dementia, and a length of stay greater than 5 days.

RESULTS

Most patients received physical assessments, including mobility (89 %), continence (84 %) and pressure sore risk (87 %); however assessment of pain (75 %), and particularly functioning (36 %) was poor. Assessment for cognition (43 %) and delirium (30 %) was inadequate. Most wards have access at least 5 days per week to Liaison Psychiatry (93 %), Geriatric Medicine (84 %), Occupational Therapy (79 %), Speech & Language (81 %), Physiotherapy (99 %), and Palliative Care (89 %) Access to Psychology (9 %), Social Work (53 %), and Continence services (34 %) is limited. Dementia awareness training is provided on induction in only 2 hospitals, and almost half of hospitals did not offer dementia training to doctors (45 %) or nurses (48 %) in the previous 12 months. Staff cover could not be provided on 62 % of wards for attending dementia training. Most wards (84 %) had no dementia champion to guide best practice in care. Discharge planning was not initiated within 24 h of admission in 72 % of cases, less than 40 % had a single plan for discharge recorded, and 33 % of carers received no needs assessment prior to discharge. Length of stay was significantly greater for new discharges to residential care (p < .001).

CONCLUSION

Dementia care relating to assessment, access to certain specialist services, staffing levels, training and support, and discharge planning is sub-optimal, which may increase the risk of adverse patient outcomes and the cost of acute care. Areas of good practice are also highlighted.

[Impact of dementia on length of stay and costs in acute care hospitals]

BACKGROUND

The treatment of patients with dementia in acute care hospitals is becoming increasingly more important. The aim of this study was to investigate and demonstrate aspects of the healthcare situation and resource consumption of dementia patients during their hospital stay in a ward for internal medicine.

MATERIAL AND METHODS

Secondary data from a ward of internal medicine were analyzed on a retrospective and case-related basis. For 100 patients a diagnosis of dementia by a general practitioner before hospitalization was identified. The control group was selected by age and sex from the other patients in the ward (n = 100). The costs were calculated on the basis of the German diagnosis-related groups (G-DRG) flat rate case classification. The relationship between dementia, deviation from the average length of stay and costs was investigated under the control of comorbidities using multivariate regression analysis.

RESULTS

Patients with dementia had poorer health at admission with respect to functionality and orientation and a higher risk of falls and pressure ulcers. During hospitalization patients with dementia fell more frequently than patients without dementia (12 % versus 3 %, p = 0.029). Regarding the average length of stay, according to the G‑DRG catalogue patients with dementia stayed 1.4 days longer in hospital than patients without dementia and caused excess costs of 19 %.

CONCLUSION

Patients with dementia are a highly vulnerable patient group with a higher consumption of resources than patients without dementia. The results demonstrate the care-related and economic consequences, which the increasing number of patients with dementia could have in the future.

Comorbidity and dementia: a mixed-method study on improving health care for people with dementia (CoDem)

Background

Among people living with dementia (PLWD) there is a high prevalence of comorbid medical conditions but little is known about the effects of comorbidity on processes and quality of care and patient needs or how services are adapting to address the particular needs of this population.

Objectives

To explore the impact of dementia on access to non-dementia services and identify ways of improving the integration of services for this population.

Design

We undertook a scoping review, cross-sectional analysis of a population cohort database, interviews with PLWD and comorbidity and their family carers and focus groups or interviews with health-care professionals (HCPs). We focused specifically on three conditions: diabetes, stroke and vision impairment (VI). The analysis was informed by theories of continuity of care and access to care.

Participants

The study included 28 community-dwelling PLWD with one of our target comorbidities, 33 family carers and 56 HCPs specialising in diabetes, stroke, VI or primary care.

Results

The scoping review (n = 76 studies or reports) found a lack of continuity in health-care systems for PLWD and comorbidity, with little integration or communication between different teams and specialities. PLWD had poorer access to services than those without dementia. Analysis of a population cohort database found that 17% of PLWD had diabetes, 18% had had a stroke and 17% had some form of VI. There has been an increase in the use of unpaid care for PLWD and comorbidity over the last decade. Our qualitative data supported the findings of the scoping review: communication was often poor, with an absence of a standardised approach to sharing information about a person’s dementia and how it might affect the management of other conditions. Although HCPs acknowledged the vital role that family carers play in managing health-care conditions of PLWD and facilitating continuity and access to care, this recognition did not translate into their routine involvement in appointments or decision-making about their family member. Although we found examples of good practice, these tended to be about the behaviour of individual practitioners rather than system-based approaches; current systems may unintentionally block access to care for PLWD. Pathways and guidelines for our three target conditions do not address the possibility of a dementia diagnosis or provide decision-making support for practitioners trying to weigh up the risks and benefits of treatment for PLWD.

Conclusions

Significant numbers of PLWD have comorbid conditions such as stroke, diabetes and VI. The presence of dementia complicates the delivery of health and social care and magnifies the difficulties that people with long-term conditions experience. Key elements of good care for PLWD and comorbidity include having the PLWD and family carer at the centre, flexibility around processes and good communication which ensures that all services are aware when someone has a diagnosis of dementia. The impact of a diagnosis of dementia on pre-existing conditions should be incorporated into guidelines and care planning. Future work needs to focus on the development and evaluation of interventions to improve continuity of care and access to services for PLWD with comorbidity.

Cognitive Impairment in Hospitalized Seniors

Cognitive disorders are highly prevalent in hospitalized seniors, and can be due to delirium, dementia, as well as other disorders. Hospitalization can have adverse cognitive effects, and cognitive dysfunction adversely affects hospital outcomes. In this article, the literature is reviewed on how hospitalization affects cognitive function and how cognitive impairment affects hospital outcomes. Possible interventions in cognitively impaired hospitalized seniors are reviewed.
