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

Preventable adverse events and related outcomes among people with dementia in hospital settings: scoping review

OBJECTIVES

To explore the hospital-related adverse events endured by people with dementia and assess their association with negative outcomes related to hospital care.

METHOD

A scoping review was undertaken in October 2023. Primary studies published in peer-reviewed journals in English, Spanish, or Portuguese were included. The databases PubMed, Web of Science, CINAHL, and Scopus were searched.

RESULTS

Of the 1976 retrieved studies, 16 were included. Adverse events were more frequent among people with dementia compared to people without dementia. In studies with non-surgical and surgical patients, the most frequently reported were falls, delirium, and infections, while in studies exclusively conducted with surgical patients, these were postoperative delirium, infections, and other complications. The link between adverse events and negative outcomes was explored in only three studies and indicated that those who experienced adverse events had longer hospital stays, higher risk of mortality, and higher readmission rates within 90 days.

CONCLUSION

Although we were unable to establish a direct link between adverse events and hospital outcomes due to the exploratory nature of this review, the findings suggest that mitigating such events could help improve outcomes among hospitalized people with dementia. Hospital safety measures appear to be insufficient to protect this group.

Inpatient Palliative Care and Healthcare Utilization Among Older Patients With Alzheimer's Disease and Related Dementia (ADRD) and High Risk of Mortality in U.S. Hospitals

Background. Despite the potential of palliative care (PC) to enhance the quality of life for patients with advanced dementia, there is limited knowledge of its inpatient utilization patterns. This study investigated inpatient PC consultation utilization patterns and evaluated its impact on hospital length of stay (LOS) and medical costs among older patients diagnosed with Alzheimer's Disease and Related Dementia who were at a high risk of mortality (ADRD-HRM). Methods. Using the 2016-2019 National Inpatient Sample database, we conducted multivariable logistic regression analyses to identify individual and hospital characteristics influencing PC consultation utilization. We subsequently performed generalized linear models to estimate LOS (using Poisson distribution) and hospital charges (via log-transformation). Results. Our sample encompassed 965,644 hospital discharges (weighted n = 4,828,219) of patients aged 65 years and above with ADRD-HRM. Among them, 14.6% received inpatient PC. There was a notable uptrend in PC consultation utilization from 13.3% in 2016 to 16.3% in 2019 (p trend<.001). Factors positively influencing and associated with PC utilization included patients that are older, non-Hispanic White, with higher income, receiving care from teaching hospitals, and facilitated with greater bed capacity (all P < .05). Although patients who received PC were more likely to have 3.0% longer LOS (P < .001), they had 19.2% lower hospital charges (P < .001). Conclusions. PC substantially reduced hospital expenditures for older patients with ADRD-HRM, but the prevalence remained low at 14.6% in the study period. Future studies should explore the unmet needs of patients with lower sociodemographic status and those in rural hospitals to further increase their PC consultation utilization.

Frailty, malnutrition, healthcare utilization, and mortality in patients with dementia and cognitive impairment obtained from hospital administrative data

Introduction

With aging populations, the prevalence of dementia, frailty and malnutrition will increase. The aim of this study is twofold (a) to determine the demographic data, including frailty and malnutrition prevalence in older patients with diagnosis of dementia and/or cognitive impairment and (b) to determine its impact on outcomes such as length of stay (LOS), readmission and mortality stratified by frailty status.

Methods

Retrospective single-center cohort study conducted using hospital database on older patients ≥65 yrs. admitted to a tertiary hospital between March 2022 and Dec 2023 and discharged with either primary or secondary diagnosis of dementia or cognitive impairment. Data on age, gender, ethnicity, comorbidities, discharge diagnoses, Hospital Frailty Risk Score (HFRS), Clinical Frailty Scale (CFS), activity of daily living (ADL), 3-Minute Nutrition Screening and outcomes such as LOS, readmission, mortality and cost of hospitalization were extracted. Those aged between 65 to 74 years old were categorized as "young-old," and ≥75 years old as "old-old."

Results

Dementia or cognitive impairment diagnosis was prevalent in 8.6% (3090) older patients, and 33.7% were malnourished. 54.5% were female with a mean age of 82.0 years. Almost one fourth were dependent on ADL. Based on frailty defined by (i) HFRS-26.0% had intermediate and 18.2% high frailty (ii) CFS-41.0% were mild/moderately frail, and 32.2% severely frail. Median LOS was 8 days. 30 and 90-days readmission rates were 23.2 and 35.4%, respectively. In-hospital mortality was 7.8% and 30-day mortality 14.0%. High HFRS (aOR 1.511, 95% CI: 1.089-2.097; p = 0.013), severe frailty (aOR 4.325, 95% CI: 0.960-2.684; p < 0.001) and terminal frailty (aOR 39.762, 95% CI: 18.311-86.344; p < 0.001) were significantly associated with inpatient mortality. Intermediate HFRS (aOR 1.682, 95% CI: 1.380-2.050; p < 0.001), mild/moderate frailty (1.609, 95% CI: 1.254-2.065; p < 0.01), high HFRS (aOR 2.178, 95% CI: 1.756-2.702; p < 0.001) and severe frailty (2.333, 95% CI: 1.804-3.017; p < 0.01) were significantly associated with 30-days readmission. The impact of malnutrition on healthcare utilization was highest in the old-old with high HFRS and severe frailty.

Conclusion

Frailty and malnutrition have significant impact on healthcare utilization, readmission rates, and mortality among older adults with dementia and/or cognitive impairment.

Post-operative periprosthetic femoral fractures in England: Patient profiles and short-term outcomes

BACKGROUND AND OBJECTIVE

Post-operative periprosthetic femoral fractures (POPFF) present a growing challenge for healthcare services, but there are limited national data on patient profiles, short-term outcomes, and post-discharge follow-up. We aimed to fill these gaps.

METHODS

Using Hospital Episode Statistics (HES), we identified POPFF discharges from hospitals in England for patients aged 18 and above between April 2016 and December 2022. We flagged prior admissions for hip fracture and elective hip or knee replacement surgery (primary, revision or re-revision) between April 2000 and the day of the POPFF admission date. We extracted information on patient factors, treatment modes for POPFF (nonoperative, fixation, revision), and outcomes (in-hospital mortality, length of stay, unplanned readmission). We used outpatient data to summarise post-hospitalisation follow-up.

RESULTS

Of 39,035 cases, 65.9 % were female; the median age was 82 years. HES data identified that 34.0 % had previously undergone elective hip replacement, 26.2 % elective knee replacement, and 22.8 % surgery for hip fracture. Those with a prior hip fracture were more likely to have delirium during the index POPFF admission, and, compared with those with a prior elective hip or knee replacement, they faced higher in-hospital mortality (5.1 % vs 3.2 % and 3.6 %, respectively), rates of readmission (15.4 % vs 13.1 % and 12.8 %, respectively), and hip re-fracture after POPFF (2.9 % vs 1.2 % and 1.6 %, respectively). Their median length of stay was longer (16 vs 14 days, p < 0.001). The most common reason for hospital readmission following POPFF was another fracture (11.3 % of all readmissions). Overall, 74 % of patients were discharged from outpatient follow-up within 12 months.

CONCLUSION

This is the first national description of the burden of adverse outcomes for people with POPFF in England, of whom a large proportion require ongoing specialist support. Fewer POPFF cases follow prior hip fracture surgery than elective joint replacement, but these patients face higher risks of worse outcomes. With an expected increasing incidence of POPFF, this may have considerable health service implications.

Insights into young-onset dementia hospitalizations: An 8-year nationwide study using administrative data

OBJECTIVE

To characterize all Portuguese public hospitalizations of patients aged < 65 years with a primary or secondary diagnosis of dementia, based on ICD-9-CM coding.

METHODS

A retrospective observational study was conducted using a nationwide database encompassing all hospitalizations occurred in Portuguese mainland public hospitals with discharge from 2008 to 2015. Hospitalizations of patients aged 35-64 years with primary or secondary diagnoses of dementia were selected based on ICD-9-CM codes 290.1X-290.4X, 291.2, 292.82, 294.1X, 294.2X, 331.0, 331.1X, 331.82, 333.4 and 046.1, excluding diagnostic codes 317-319, 330.X, 343, 758.0-758.3 and 759.3. Information on age, sex, primary diagnosis, comorbidities (secondary diagnosis), type of admission, length of stay (LoS), in-hospital mortality, suicide attempts, discharge destination, readmissions and dementia etiology was collected.

RESULTS

From 7971 hospitalizations, for 5682 inpatients, the median age was 57.3 years (SD±6.5) and 61.8% were of male patients. Vascular dementia was the most prevalent etiology, followed by Alzheimer's disease. Most admissions were urgent and had a primary diagnosis of 'Delirium, dementia and other cognitive disorders', followed by pneumonia and alcohol-related disorders. Dementia, cerebrovascular disease and diabetes were the most common comorbidities. Overall, 55.4% of admissions were first-time admissions during the study period and the median LoS was 10.0 days (Q1;Q3: 5.0;20.0). Suicide attempts were recorded in 0.6% of the episodes. The in-hospital mortality rate was 9.2% and most patients were discharged home (80.2%).

CONCLUSIONS

This study describes the complexity and strain of young-onset dementia hospitalizations providing a detailed overview and recommendations for further research and tailored interventions.

No Place to Go: The Relationship Between Care Partner Inclusion Practices and the Hospital Environment

OBJECTIVE

The objective of this was to explore how the physical environment in a hospital contributes to care partner inclusion practices.

BACKGROUND

Despite their vital efforts in caring for people living with dementia (PLWD), care partners of PLWD often report feeling not included in their loved ones' hospitalizations. This phenomenon goes against research, policy initiatives, and hospital design frameworks that underscore the importance of including care partners in hospital care. To ensure that care partners are systematically included in hospital care, health systems must create an environment that prioritizes care partners' presence.

METHODS

This descriptive qualitative design employs a multimethod approach to data collection. Our team conducted direct observations in a large academic hospital and interviewed 23 clinicians/administrators and 15 care partners of PLWD to understand the relationship between hospital environments and care partner inclusion. Observational data were analyzed using a framework analysis, and interview data were analyzed through thematic analysis.

RESULTS

Direct observations revealed an underutilization of environmental resources such as family-centered spaces and environmental communication tools. Interview data revealed that adequate space for care partners, the layout of patient rooms, parking accessibility, room personalization, and comfort level of the hospital space all impact care partner inclusion.

CONCLUSION

Our findings highlight opportunities for health systems to create hospital environments that support PLWD and their care partners. In pursuit of systematic care partner inclusion, health systems can make adequate space for care partners, allocate dementia-friendly parking spaces, increase utilization of environmental communication tools, and increase comfort level of the environment.

Hospitalization outcomes among older adults living undiagnosed or unaware of dementia

INTRODUCTION

Many persons with dementia are undiagnosed or unaware of dementia, which may affect hospitalization outcomes.

METHODS

We evaluated differences in length of stay, days not at home, discharge destination, and 30-day readmissions over 1 year in 6296 older adults in the National Health and Aging Trends Study with linked Medicare claims. Multivariable-adjusted models compared outcomes across no dementia, undiagnosed dementia, unaware but diagnosed with dementia, and aware and diagnosed with dementia.

RESULTS

Persons with undiagnosed dementia had longer length of stay and were more likely to be discharged to a facility (44.8% vs. 19.3%) compared to no dementia; differences persisted in multivariable models. Persons undiagnosed or unaware experienced outcomes similar to persons aware and diagnosed except for more 30-day readmissions in the undiagnosed (adjusted odds ratio [95% confidence interval] 2.05 [1.01, 4.16]).

DISCUSSION

Persons undiagnosed or unaware of dementia experience worse hospitalization outcomes, suggesting potential clinically significant implications of unrecognized dementia.

Highlights

Persons with undiagnosed versus no dementia have worse hospitalization outcomes.Persons with undiagnosed dementia have more 30-day readmissions compared to persons diagnosed.Lack of clinician or family recognition of dementia may adversely affect hospitalization outcomes.

The Impact of Comorbid Dementia and Diabetes Mellitus on Hospital Patients' Outcomes: A Systematic Review and Meta-analysis

INTRODUCTION

Previous reviews have demonstrated that dementia and diabetes mellitus, separately, can worsen the hospital outcomes of patients. Unfortunately, there are no systematic evaluations regarding the hospital outcomes of patients with dementia and diabetes mellitus as a comorbidity. Therefore, our review aimed to determine any differences in hospital length of stay, hospital mortality, and hospital readmission between patients with the comorbidity and patients without.

METHODS

Searches were conducted of Medline, CINHAL, EMBASE, PsychINFO, Web of Science and Google Scholar for original studies. All studies were quality assessed using the Joanna Briggs Institute critical appraisal tools. Where possible, studies were pooled in a meta-analysis to generate odds ratios (OR) with 95% confidence intervals (CI).

RESULTS

Sixteen studies were included in this review. When comparing patients with the comorbidity to patients with dementia, the difference in length of stay was inconclusive, and there was no difference in the odds of hospital mortality (OR = 0.98, 95% CI 0.91-1.06). However, patients with the comorbidity had increased odds of 30-day readmission compared to patients with dementia alone (OR = 1.20, 95% CI 1.14-1.26). When comparing patients with the comorbidity to patients with diabetes, those with the comorbidity had a longer length of stay and but no difference in the odds of hospital mortality (OR = 1.48, 95% CI 0.84-2.62). Additionally, those with the comorbidity may have worse readmission outcomes than those with diabetes alone.

CONCLUSIONS

Our findings suggest that patients with comorbid dementia and diabetes mellitus may have worse hospital outcomes. Therefore, we recommend further research to assess these patients' hospital outcomes to resolve the discrepancies found.

The association of comorbid dementia with length of stay, cost and mortality among older adults in US acute hospitals: An observational study

BACKGROUND

Although overall health and social care expenditures among persons with dementia are larger than for other diseases, the resource and cost implications of a comorbid diagnosis of dementia in acute hospitals in the U.S. are largely unknown. We estimate the difference in inpatient outcomes between similar hospital admissions for patients with and without comorbid dementia (CD).

METHODS

Inpatient admissions, from the U.S. National Inpatient Sample (2016-2019), were stratified according to hospital characteristics and primary diagnosis (using ICD-10-CM codes), and entropy balanced within strata according to patient and hospital characteristics to create two comparable groups of admissions for patients (aged 65 years or older) with and without CD (a non-primary diagnosis of dementia). Generalized linear regression modeling was then used to estimate differences in length of stay (LOS), cost, absolute mortality risk and number of procedures between these two groups.

RESULTS

The final sample consisted of 8,776,417 admissions, comprised of 1,013,879 admissions with and 7,762,538 without CD. CD was associated with on average 0.25 (95 % CI: 0.24-0.25) days longer LOS, 0.4 percentage points (CI: 0.37-0.42) higher absolute mortality risk, $1187 (CI: -1202 to -1171) lower inpatient costs and 0.21 (CI: -0.214 to -0.210) fewer procedures compared to similar patients without CD.

CONCLUSION

Comorbid dementia is associated with longer LOS and higher mortality in acute hospitals but lower inpatient costs and fewer procedures. This highlights potential communication issues between dementia patients and hospital staff, with patients struggling to express their needs and staff lacking sufficient dementia training to address communication challenges.

Proactive integrated consultation-liaison psychiatry and time spent in hospital by older medical inpatients in England (The HOME Study): a multicentre, parallel-group, randomised controlled trial

BACKGROUND

Older people admitted to hospital in an emergency often have prolonged inpatient stays that worsen their outcomes, increase health-care costs, and reduce bed availability. Growing evidence suggests that the biopsychosocial complexity of their problems, which include cognitive impairment, depression, anxiety, multiple medical illnesses, and care needs resulting from functional dependency, prolongs hospital stays by making medical treatment less efficient and the planning of post-discharge care more difficult. We aimed to assess the effects of enhancing older inpatients' care with Proactive Integrated Consultation-Liaison Psychiatry (PICLP) in The HOME Study. We have previously described the benefits of PICLP reported by patients and clinicians. In this Article, we report the effectiveness and cost-effectiveness of PICLP-enhanced care, compared with usual care alone, in reducing time in hospital.

METHODS

We did a parallel-group, multicentre, randomised controlled trial in 24 medical wards of three English acute general hospitals. Patients were eligible to take part if they were 65 years or older, had been admitted in an emergency, and were expected to remain in hospital for at least 2 days from the time of enrolment. Participants were randomly allocated to PICLP or usual care in a 1:1 ratio by a database software algorithm that used stratification by hospital, sex, and age, and randomly selected block sizes to ensure allocation concealment. PICLP clinicians (consultation-liaison psychiatrists supported by assisting clinicians) made proactive biopsychosocial assessments of patients' problems, then delivered discharge-focused care as integrated members of ward teams. The primary outcome was time spent as an inpatient (during the index admission and any emergency readmissions) in the 30 days post-randomisation. Secondary outcomes were the rate of discharge from hospital for the total length of the index admission; discharge destination; the length of the index admission after random allocation truncated at 30 days; the number of emergency readmissions to hospital, the number of days spent as an inpatient in an acute general hospital, and the rate of death in the year after random allocation; the patient's experience of the hospital stay; their view on the length of the hospital stay; anxiety (Generalized Anxiety Disorder-2); depression (Patient Health Questionnaire-2); cognitive function (Montreal Cognitive Assessment-Telephone version); independent functioning (Barthel Index of Activities of Daily Living); health-related quality of life (five-level EuroQol five-dimension questionnaire); and overall quality of life. Statisticians and data collectors were masked to treatment allocation; participants and ward staff could not be. Analyses were intention-to-treat. The trial had a patient and public involvement panel and was registered with ISRTCN (ISRCTN86120296).

FINDINGS

2744 participants (1399 [51·0%] male and 1345 [49·0%] female) were enrolled between May 2, 2018, and March 5, 2020; 1373 were allocated to PICLP and 1371 to usual care. Participants' mean age was 82·3 years (SD 8·2) and 2565 (93·5%) participants were White. The mean time spent in hospital in the 30 days post-randomisation (analysed for 2710 [98·8%] participants) was 11·37 days (SD 8·74) with PICLP and 11·85 days (SD 9·00) with usual care; adjusted mean difference -0·45 (95% CI -1·11 to 0·21; p=0·18). The only statistically and clinically significant difference in secondary outcomes was the rate of discharge, which was 8.5% higher (rate ratio 1·09 [95% CI 1·00 to 1·17]; p=0·042) with PICLP-a difference most apparent in patients who stayed for more than 2 weeks. Compared with usual care, PICLP was estimated to be modestly cost-saving and cost-effective over 1 and 3, but not 12, months. No intervention-related serious adverse events occurred.

INTERPRETATION

This is the first randomised controlled trial of PICLP. PICLP is experienced by older medical inpatients and ward staff as enhancing medical care. It is also likely to be cost-saving in the short-term. Although the trial does not provide strong evidence that PICLP reduces time in hospital, it does support and inform its future development and evaluation.

COVID-19 outcomes among patients with dementia and age-matched controls who were hospitalized in 21 US health-care systems

INTRODUCTION

COVID-19 had devastating impacts worldwide. However, most research examining the impact of dementia on COVID-19 outcomes has been conducted in Europe and Asia and has not examined dementia subtypes.

METHODS

A retrospective analysis of electronic health record data from 21 US health-care systems examined relationships of all-cause dementia, Alzheimer's disease (AD), and vascular dementia with in-hospital mortality, intensive care unit (ICU) admission, and hospital stay duration.

RESULTS

All-cause dementia, but not AD or vascular dementia independently, was associated with increased mortality risk, the inclusion of discharge to hospice as a mortality equivalent increased risk for mortality for all-cause dementia, and AD and vascular dementia. Patients with all-cause dementia and AD were less likely to be admitted to the ICU than patients without. Patients with any form of dementia had longer hospital stays than patients without.

DISCUSSION

Dementia was associated with increased mortality or hospice discharge, decreased ICU admissions, and longer hospital stays.

HIGHLIGHTS

Only all-cause dementia was associated with increased mortality risk. This risk was lower than what has been published in previous research. Combining mortality and hospice discharge increased risk for all dementia subtypes. All-cause and Alzheimer's disease (AD) dementia were associated with decreased intensive care unit admissions. All-cause, vascular, and AD dementia were associated with longer hospital stays.

The Clinical Impact of Hospital-Acquired Adverse Drug Reactions in Older Adults: An Australian Cohort Study

INTRODUCTION

Hospital-acquired adverse drug reactions (HA-ADRs) are common in older adults. However, there is limited knowledge regarding the association between HA-ADRs and adverse clinical outcomes.

OBJECTIVE

To investigate the incidence and characteristics of HA-ADRs in older adults, and any association with mortality, length of stay, and readmissions.

DESIGN

Prospective cohort study.

SETTING AND PARTICIPANTS

Flinders Medical Centre, a large tertiary referral hospital in Adelaide, South Australia. Older adults admitted under the General Medicine and Acute Care of the Elderly units with no previous diagnosis of dementia.

METHODS

All patients had a Multidimensional Prognostic Index (MPI) assessment performed within 3 days of the admission. Data collected included age, gender, estimated glomerular filtration rate (eGFR), length of stay, readmissions, and mortality. HA-ADRs were identified by review of individual discharge summaries. Univariate and multivariate analyses were performed to investigate associations with clinical outcomes including mortality, length of stay, and readmissions. Exploratory analyses were performed for HA-ADR groups based on Medical Dictionary for Regulatory Activities System Organ Class and World Health Organization Anatomical Therapeutic Chemical classifications that accounted for ≥10% of all HA-ADRs.

RESULTS

There were 737 patients in the cohort with 72 having experienced a HA-ADRs (incidence = 9.8%). Patients with an HA-ADR had increased length of stay and 30-day readmissions compared with those without an HA-ADR. In multivariate analysis, the number of HA-ADRs was associated with in-hospital mortality and length of stay but not post-discharge mortality or readmissions within 30 days. In exploratory analyses, patients with an HA-ADR to antibacterial drugs had significantly higher rates of in-hospital mortality compared with those without these reactions.

CONCLUSIONS AND IMPLICATIONS

The number of HA-ADRs are associated with in-hospital mortality and length of stay in older Australian inpatients. The occurrence of HA-ADRs may be a trigger to offer advice to prescribers to prevent future ADRs to similar agents and proactively manage disease to improve health outcomes.

A Scoping Review on Nurse's Pain Management of Older Patients with Dementia in a Hospital Environment

OBJECTIVES

Hospitalized persons living with dementia often experience unrelieved pain. Unmanaged pain during hospitalization has a significant negative effect on quality of life for persons living with dementia. Despite the central role of nurses in pain management, little is known about how nurses manage pain in this patient population in the hospital environment.

DESIGN

A scoping review explored the nurses' pain management practices when caring for persons living with dementia in a hospital setting.

DATA SOURCES AND REVIEW/ANALYSIS METHODS

After an extensive search for all available evidence on how nurses manage pain in hospitalized persons living with dementia, data were extracted on pain management methods that included assessment, intervention, effectiveness of pain management, and the barriers nurses encountered when managing pain. A descriptive content analysis was used to extract data from qualitative studies.

RESULTS

Six articles published between 2016 and 2021 met the inclusion criteria; four utilized qualitative methods, and the others used mixed-methods and quantitative study designs. A narrative description of the findings was summarized after data were categorized into pain management data elements and barriers nurses encountered when managing pain. Barriers were grouped into the subcategories of communication challenges (nurse to patient), information sharing (nurse to nurse), lack of knowledge, time constraints, and nursing stressors.

CONCLUSION

We identified six articles that met our inclusion criteria, highlighting a noticeable gap in the literature. Managing pain in this population is complex and lacks organizational support. Review findings indicate that pain management methods lack consistency and standardization, making it difficult to assess their effectiveness. Nurses also described knowledge deficits resulting in practice gaps that, when combined with barriers and challenges, result in underrecognized and undermanaged pain.

Feasibility of Identifying Factors Related to Alzheimer's Disease and Related Dementia in Real-World Data

A comprehensive view of factors associated with AD/ADRD will significantly aid in studies to develop new treatments for AD/ADRD and identify high-risk populations and patients for prevention efforts. In our study, we summarized the risk factors for AD/ADRD by reviewing existing meta-analyses and review articles on risk and preventive factors for AD/ADRD. In total, we extracted 477 risk factors in 10 categories from 537 studies. We constructed an interactive knowledge map to disseminate our study results. Most of the risk factors are accessible from structured Electronic Health Records (EHRs), and clinical narratives show promise as information sources. However, evaluating genomic risk factors using RWD remains a challenge, as genetic testing for AD/ADRD is still not a common practice and is poorly documented in both structured and unstructured EHRs. Considering the constantly evolving research on AD/ADRD risk factors, literature mining via NLP methods offers a solution to automatically update our knowledge map.

Mortality Among the Dementia Population in Not-For-Profit Hospitals with Better Nursing Resources

The dementia population has higher rates of mortality during hospital stays than those without dementia. The aim of this study is to examine the relationship between ownership status (i.e. for-profit vs. not-for-profit) and nursing resources (i.e. nurse work environment, nurse-to-patient staffing, and nurse education) on 30-day mortality among post-surgical older adults with dementia. A cross-sectional analysis of linked American Hospital Association, Medicare claims, and nurse survey data was conducted using multi-level logistic regression models. We examined these models to assess the relationship between ownership status and 30-day mortality after adjusting patient and hospital characteristics. We also analyzed the relationship between the hospital ownership status and the 30-day mortality, after considering the three nursing resources. Older adults with dementia who received care in hospitals with not-for-profit status were less likely to die within 30 days of admission following surgery compared to those treated in hospitals with for-profit hospital status (i.e. odds ratio 0.82, 95% confidence interval 0.73-0.92, p = <.001). In addition, the odds ratios estimating the association between ownership and mortality were similar across the different models of the three nursing resources with and without those controls (i.e. 0.88 vs. 0.83 vs. 0.82). Surgical patients with dementia had better outcomes when cared for in not-for-profit hospitals, particularly with greater levels of nurse education and nurse staffing. The relationship between profit status and mortality was partly explained by the lower levels of nurse staffing and education in for-profit vs. not-for-profit hospitals.

Proactive and integrated consultation-liaison psychiatry for older medical inpatients: A mixed methods description of training, care provided and clinician experience in the HOME study

OBJECTIVES

To describe the practical experience of delivering a proactive and integrated consultation-liaison (C-L) psychiatry service model (PICLP). PICLP is designed for older medical inpatients and is explicitly biopsychosocial and discharge-focused. In this paper we report: (a) observations on the training of 15 clinicians (seven senior C-L psychiatrists and eight assisting clinicians) to deliver PICLP; (b) the care they provided to 1359 patients; (c) their experiences of working in this new way.

METHOD

A mixed methods observational study using quantitative and qualitative data, collected prospectively over two years as part of The HOME Study (a randomized trial comparing PICLP with usual care).

RESULTS

The clinicians were successfully trained to deliver PICLP according to the service manual. They proactively assessed all patients and found that most had multiple biopsychosocial problems impeding their timely discharge from hospital. They integrated with ward teams to provide a range of interventions aimed at addressing these problems. Delivering PICLP took a modest amount of clinical time, and the clinicians experienced it as both clinically valuable and professionally rewarding.

CONCLUSION

The experience of delivering PICLP highlights the special role that C-L psychiatry clinicians, working in a proactive and integrated way, can play in medical care.

Impact of Dementia on Incidence and Severity of Postoperative Pulmonary Complications Following Hip Fracture Surgery Among Older Patients

Postoperative pulmonary complications (PPCs) are the leading cause of death following hip fracture surgery. Dementia has been identified as a PPC risk factor that complicates the clinical course. By leveraging electronic health records, this retrospective observational study evaluated the impact of dementia on the incidence and severity of PPCs, hospital length of stay, and postoperative 30-day mortality among 875 older patients (≥65 years) who underwent hip fracture surgery between October 1, 2015 and December 31, 2018 at a health system in the southeastern United States. Inverse probability of treatment weighting using propensity scores was utilized to balance confounders between patients with and without dementia to isolate the impact of dementia on PPCs. Regression analyses revealed that dementia did not have a statistically significant impact on the incidence and severity of PPCs or postoperative 30-day mortality. However, dementia significantly extended the hospital length of stay by an average of 1.37 days.

Factors associated with longer hospital admission in elderly patients with major neurocognitive disorder

Background

Major neurocognitive disorder presents many challenges to patients, families and healthcare systems, especially when a patient requires admission to a psychiatric hospital.

Aim

To identify characteristics of older patients with major neurocognitive disorder at risk of prolonged admission in a psychiatric hospital.

Setting

A tertiary psychiatric hospital in Gauteng province, South Africa.

Methods

The authors conducted a retrospective review of the hospital database and clinical files. Clinical and demographic data were collected from the files of 50 inpatients, 60 years and older, who were diagnosed with major neurocognitive disorder and admitted between 2015 and 2019. Anonymised data from patient records were captured on an electronic spreadsheet and analysed using T-tests and analysis of variance (ANOVA) to investigate the relationship between patient characteristics and length of hospital admission.

Results

The mean duration of admission was 18.29 months. Involuntary admission status (β = 0.239, p = 0.049), level of assistance required (moderate level of assistance [β = 0.378, p = 0.005]; high level of assistance [β = 0.336, p = 0.015]), availability of social support (β = -0.319, p = 0.016) and the presence of behavioural or psychological problems (β = 0.437, p = 0.002) were significantly correlated with longer admission. Using a stepwise regression model, the only significant variable associated with a shorter length of stay was the presence of social support (β = -0.512, p = 0.009). Age, type of major neurocognitive disorder and number of comorbidities were not correlated with the duration of admission (p > 0.005).

Conclusion and contribution

Social support plays an important role in the management of patients with major neurocognitive disorder. The findings in this study highlight healthcare shortages and a need for adequate placement facilities in South Africa for patients who have no other form of support.

Visual identifiers for people with dementia in hospitals: a qualitative study to unravel mechanisms of action for improving quality of care

BACKGROUND

Hospitalised people with dementia (PwD) experience worse care and more patient safety incidents than non-dementia patients. Visual identifiers are commonly used to identify patients who have a diagnosis of dementia, with the aim of promoting more personalised care. However, little is known about how they work in practice, nor about the potential unintended consequences that might arise from their use. We aim to identify the mechanisms through which visual identifiers could support good care for PwD, how and why their use may have negative consequences and the conditions for their effective use.

METHODS

We conducted interviews with 21 dementia leads and healthcare professionals, 19 carers and two PwD, and produced case studies of visual identification systems in four UK acute hospital trusts between 2019 and 2021. Analysis drew on the concept of classification to identify and explore mechanisms of action.

RESULTS

We identified four mechanisms through which visual identifiers could help towards providing good care for PwD: enabling coordination of care at organisational level; signalling eligibility for dementia-specific interventions; informing prioritisation of resources on wards; and acting as a quick reference cue for staff. But identifier effectiveness could be undermined by: lack of standardisation and consistency; a lack of closely coupled information about individual needs; and stigma associated with a dementia diagnosis. Identifier effectiveness was dependent on their implementation being supported through staff training, resources directed and efforts to develop a supportive culture for caring for this patient group.

CONCLUSION

Our research highlights the potential mechanisms of action of visual identifiers and their possible negative consequences. Optimising the use of identifiers requires consensus on the rules of classification and the symbols used, and closely coupled patient information. Organisations need to provide support, offer the right resources and training and engage meaningfully with carers and patients about the use of identifiers.

Structural capabilities in primary care practices where nurse practitioners care for persons living with dementia

BACKGROUND

Primary care structural capabilities (i.e., electronic health records, care coordination, community integration, and reminder systems) can address the multiple needs of persons living with dementia (PLWD).

OBJECTIVES

This study describes structural capabilities in primary care practices where nurse practitioners (NPs) provide care to PLWD and compares the presence of structural capabilities in practices with a high and low volume of PLWD.

METHODS

We conducted a secondary analysis of cross-sectional data from 293 NPs in 259 practices in California. Logistic regression models were used to determine the association between the volume of PLWD and the presence of structural capabilities.

RESULTS

NPs reported that 96% of practices had electronic health records, 61% had community integration, 55% had reminder systems and 35% had care coordination capabilities. Practices with a high volume of PLWD were less likely to have community integration compared to practices with a low volume of PLWD.

CONCLUSION

Many PLWD-serving practices do not have the essential infrastructure for providing optimal dementia care. Practice managers should focus on implementing the essential structural capabilities to address the complex needs of PLWD.

IMPLICATIONS FOR PRACTICE

Clinicians and practice administrations can use the findings of this study to improve the delivery of care in practices that provide care to PLWD.

Mapping implementation strategies of evidence-based interventions for three preselected phenomena in people with dementia-a scoping review

BACKGROUND

Caring for people with dementia is complex, and there are various evidence-based interventions. However, a gap exists between the available interventions and how to implement them. The objectives of our review are to identify implementation strategies, implementation outcomes, and influencing factors for the implementation of evidence-based interventions that focus on three preselected phenomena in people with dementia: (A) behavior that challenges supporting a person with dementia in long-term care, (B) delirium in acute care, and (C) postacute care needs.

METHODS

We conducted a scoping review according to the description of the Joanna Briggs Institute. We searched MEDLINE, CINAHL, and PsycINFO. For the data analysis, we conducted deductive content analysis. For this analysis, we used the Expert Recommendations for Implementation Change (ERIC), implementation outcomes according to Proctor and colleagues, and the Consolidated Framework for Implementation Research (CFIR).

RESULTS

We identified 362 (A), 544 (B), and 714 records (C) on the three phenomena and included 7 (A), 3 (B), and 3 (C) studies. Among the studies, nine reported on the implementation strategies they used. Clusters with the most reported strategies were adapt and tailor to context and train and educate stakeholders. We identified one study that tested the effectiveness of the applied implementation strategy, while ten studies reported implementation outcomes (mostly fidelity). Regarding factors that influence implementation, all identified studies reported between 1 and 19 factors. The most reported factors were available resources and the adaptability of the intervention. To address dementia-specific influencing factors, we enhanced the CFIR construct of patient needs and resources to include family needs and resources.

CONCLUSIONS

We found a high degree of homogeneity across the different dementia phenomena, the evidence-based interventions, and the care settings in terms of the implementation strategies used, implementation outcomes measured, and influencing factors identified. However, it remains unclear to what extent implementation strategies themselves are evidence-based and which intervention strategy can be used by practitioners when either the implementation outcomes are not adjusted to the implementation strategy and/or the effects of implementation strategies are mostly unknown. Future research needs to focus on investigating the effectiveness of implementation strategies for evidence-based interventions for dementia care.

Electronic Health Record Usability and Postsurgical Outcomes Among Older Adults With Dementia

INTRODUCTION

Electronic health record (EHR) usability, defined as the extent to which the system can be used to complete tasks, can influence patient outcomes. The aim of this study is to assess the relationship between EHR usability and postsurgical outcomes of older adults with dementia including 30-day readmission, 30-day mortality, and length of stay (LOS).

METHODS

A cross-sectional analysis of linked American Hospital Association, Medicare claims data, and nurse survey data was conducted using logistic regression and negative binominal models.

RESULTS

The dementia population who received care in hospitals with better EHR usability were less likely to die within 30 days of their admission following surgery compared to hospitals with poorer EHR usability (OR: 0.79, 95% CI: 0.68-0.91, p = 0.001). EHR usability was not associated with readmission or LOS.

DISCUSSION

Better nurse reported EHR usability has the potential to reduce mortality rates among older adults with dementia in hospitals.

Adapting and Testing the Care Partner Hospital Assessment Tool for Use in Dementia Care: Protocol for a 2 Sequential Phase Study

BACKGROUND

Research and policy demonstrate the value of and need for systematically identifying and preparing care partners for their caregiving responsibilities while their family member or friend living with dementia is hospitalized. The Care Partner Hospital Assessment Tool (CHAT) has undergone content and face validation and has been endorsed as appropriate by clinicians to facilitate the timely identification and preparation of care partners of older adult patients during their hospitalization. However, the CHAT has not yet been adapted or prospectively evaluated for use with care partners of hospitalized people living with dementia. Adapting and testing the CHAT via a pilot study will provide the necessary evidence to optimize feasibility and enable future efficacy trials.

OBJECTIVE

The purpose of this paper is to describe the study protocol for the adaptation and testing of the CHAT for use among care partners of hospitalized people living with dementia to better prepare them for their caregiving responsibilities after hospital discharge.

METHODS

Our protocol is based on the National Institutes of Health Stage Model and consists of 2 sequential phases, including formative research and the main trial. In phase 1, we will use a participatory human-centered design process that incorporates people living with dementia and their care partners, health care administrators, and clinicians to adapt the CHAT for dementia care (ie, the Dementia CHAT [D-CHAT]; stage IA). In phase 2, we will partner with a large academic medical system to complete a pilot randomized controlled trial to examine the feasibility and estimate the size of the effect of the D-CHAT on care partners' preparedness for caregiving (stage IB). We anticipate this study to take approximately 60 months to complete, from study start-up procedures to dissemination. The 2 phases will take place between December 1, 2022, and November 30, 2027.

RESULTS

The study protocol will yield (1) a converged-upon, ready-for-feasibility testing D-CHAT; (2) descriptive and feasibility characteristics of delivering the D-CHAT; and (3) effect size estimates of the D-CHAT on care partner preparedness. We anticipate that the resultant D-CHAT will provide clinicians with guidance on how to identify and better prepare care partners for hospitalized people living with dementia. In turn, care partners will feel equipped to fulfill caregiving roles for their family members or friends living with dementia.

CONCLUSIONS

The expected results of this study are to favorably impact hospital-based care processes and outcomes for people living with dementia and their care partners and to elucidate the essential caregiving role that so many care partners of people living with dementia assume.

Care Partner Inclusion of People Hospitalized With Alzheimer Disease and Related Dementias: Protocol for a Mixed Methods Systems Engineering Approach to Designing a Health Care System Toolkit

BACKGROUND

Research and policy demonstrate the value and need for the systematic inclusion of care partners in hospital care delivery of people living with Alzheimer disease and related dementias (ADRD). Support provided to care partners through information and training regarding caregiving responsibilities is important to facilitating their active inclusion and ultimately improving hospital outcomes of people living with ADRD. To promote care partners' active inclusion, a toolkit that guides health systems in the identification, assessment, and training of care partners is needed. User-centered approaches can address this gap in practice by creating toolkits that are practical and responsive to the needs of care partners and their hospitalized family members and friends living with ADRD.

OBJECTIVE

This paper describes the study protocol for the development and refinement of the ADRD Systematic Hospital Inclusion Family Toolkit (A-SHIFT). A-SHIFT will provide health care systems with guidance on how to effectively identify, assess, and train care partners of hospitalized persons living with ADRD.

METHODS

The A-SHIFT study protocol will use a 3-aimed, convergent mixed method approach to iteratively develop and refine the toolkit. In Aim 1, we will use a systems-engineering approach to characterize patterns of care partner inclusion in hospital care for people living with ADRD. In Aim 2, we will partner with stakeholders to identify and prioritize health care system facilitators and barriers to the inclusion for care partners of hospitalized people living with ADRD. In Aim 3, we will work with stakeholders to co-design an adaptable toolkit to be used by health systems to facilitate the identification, assessment, and training of care partners of hospitalized people living with ADRD. Our convergent mixed method approach will facilitate triangulation across all 3 aims to increase the credibility and transferability of results. We anticipate this study to take 24 months between September 1, 2022, and August 31, 2024.

RESULTS

The A-SHIFT study protocol will yield (1) optimal points in the hospital workflow for care partner inclusion, (2) a prioritized list of potentially modifiable barriers and facilitators to including care partners in the hospitalization of people living with ADRD, and (3) a converged-upon, ready for feasibility testing of the toolkit to guide the inclusion of care partners of people living with ADRD in hospital care.

CONCLUSIONS

We anticipate that the resultant A-SHIFT will provide health systems with a readiness checklist, implementation plan, and resources for identifying, assessing, and training care partners on how to fulfill their caregiving roles for people living with ADRD after hospital discharge. A-SHIFT has the potential to not only improve care partner preparedness but also help reduce health and service use outcomes for people living with ADRD after hospital discharge.

Dementia-related agitation: a 6-year nationwide characterization and analysis of hospitalization outcomes

OBJECTIVES

To characterize all hospitalizations held in mainland Portugal (2010-2015) with dementia-related agitation based on International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) coding, and to investigate whether there is a relationship between agitation and hospitalization outcomes.

METHODS

A retrospective observational study was conducted using an administrative dataset containing data from all mainland Portuguese public hospitals. Only hospitalization episodes for patients aged over 65 years who have received a dementia diagnosis ascertained by an ICD-9-CM code of dementia with behavioral disturbance (294.11 and 294.21) and dementia without behavioral disturbance (294.10 and 294.20) were selected. Episodes were further grouped according to the presence of an agitation code. For each episode, demographic data and hospitalization outcomes, including length of stay (LoS), in-hospital mortality, discharge destination and all-cause hospital readmissions, were sourced from the dataset. Comparative analyses were performed and multivariable logistic methods were used to estimate the adjusted associations between agitation (exposure) and outcomes.

RESULTS

Overall, 53,156 episodes were selected, of which 6,586 had an agitation code. These were mostly related to male, younger inpatients (mean 81.19 vs. 83.29 years, p < 0.001), had a higher comorbidity burden, stayed longer at the hospital (median 9.00 vs. 8.00 days, p < 0.001) and frequently ended being transferred to another facility with inpatient care. Agitation was shown to independently increase LoS (aOR = 1.385; 95%CI:1.314-1.461), but not the risk of a fatal outcome (aOR = 0.648; 95%CI:0.600-0.700).

CONCLUSION

These results support the importance of detecting and managing agitation early on admission, since its prompt management may prevent lengthy disruptive hospitalizations.

Clinical Quality Indicators for Monitoring Hospitalizations Among Older People with Dementia Accessing Aged Care Services

BACKGROUND

There is a need for clinical quality indicators (CQIs) that can be applied to dementia quality registries to monitor care outcomes for people with Alzheimer's disease and other forms of dementia.

OBJECTIVE

To develop tertiary and primary care-based dementia CQIs for application to clinical registries for individuals with dementia accessing aged care services and determine 1) annual trends in CQI incidence between 2011-2012 and 2015-2016, 2) associated factors, and 3) geographic and facility variation in CQI incidence.

METHODS

This retrospective repeated cross-sectional study included non-Indigenous individuals aged 65-105 years who lived with dementia between July 2008-June 2016, were assessed for government-funded aged care services, and resided in New South Wales or Victoria (n = 180,675). Poisson or negative binomial regression models estimated trends in annual CQI incidence and associated factors. Funnel plots examined CQI variation.

RESULTS

Between 2011-2012 and 2015-2016, CQI incidence increased for falls (11.0% to 13.9%, adjusted incidence rate ratio (aIRR) 1.05 (95% CI 1.01-1.06)) and delirium (4.7% to 6.7%, aIRR 1.09 (95% CI 1.07-1.10)), decreased for unplanned hospitalizations (28.7% to 27.9%, aIRR 0.99 (95% CI 0.98-0.99)) and remained steady for fracture (6.2% to 6.5%, aIRR 1.01 (95% CI 0.99-1.01)) and pressure injuries (0.5% to 0.4%, aIRR 0.99 (95% CI 0.96-1.02)). Being male, older, having more comorbidities and living in a major city were associated with higher CQI incidence. Considerable geographical and facility variation was observed for unplanned hospitalizations and delirium CQIs.

CONCLUSIONS

The CQI results highlighted considerable morbidity. The CQIs tested should be considered for application in clinical quality registries to monitor dementia care quality.

Retrospective study of more than 5 million emergency admissions to hospitals in England: Epidemiology and outcomes for people with dementia

INTRODUCTION

People living with dementia (PwD) admitted in emergency to an acute hospital may be at higher risk of inappropriate care and poorer outcomes including longer hospitalisations and higher risk of emergency re-admission or death. Since 2009 numerous national and local initiatives in England have sought to improve hospital care for PwD. We compared outcomes of emergency admissions for cohorts of patients aged 65+ with and without dementia at three points in time.

METHODS

We analysed emergency admissions (EAs) from the Hospital Episodes Statistics datasets for England 2010/11, 2012/13 and 2016/17. Dementia upon admission was based on a diagnosis in the patient's hospital records within the last five years. Outcomes were length of hospital stays (LoS), long stays (> = 15 days), emergency re-admissions (ERAs) and death in hospital or within 30 days post-discharge. A wide range of covariates were taken into account, including patient demographics, pre-existing health and reasons for admission. Hierarchical multivariable regression analysis, applied separately for males and females, estimated group differences adjusted for covariates.

RESULTS

We included 178 acute hospitals and 5,580,106 EAs, of which 356,992 (13.9%) were male PwD and 561,349 (18.6%) female PwD. Uncontrolled differences in outcomes between the patient groups were substantial but were considerably reduced after control for covariates. Covariate-adjusted differences in LoS were similar at all time-points and in 2016/17 were 17% (95%CI 15%-18%) and 12% (10%-14%) longer for male and female PwD respectively compared to patients without dementia. Adjusted excess risk of an ERA for PwD reduced over time to 17% (15%-18%) for males and 17% (16%-19%) for females, but principally due to increased ERA rates amongst patients without dementia. Adjusted overall mortality was 30% to 40% higher for PwD of both sexes throughout the time-period; however, adjusted in-hospital rates of mortality differed only slightly between the patient groups, whereas PwD had around double the risk of dying within 30 days of being discharged.

CONCLUSION

Over the six-year period, covariate-adjusted hospital LoS, ERA rates and in-hospital mortality rates for PwD were only slightly elevated compared to similar patients without dementia and remaining differences potentially reflect uncontrolled confounding. PwD however, were around twice as likely to die shortly after discharge, the reasons for which require further investigation. Despite being widely used for service evaluation, LoS, ERA and mortality may lack sensitivity to changes in hospital care and support to PwD.

Factors influencing length of hospital stay among veterans admitted to an inpatient psychiatric unit

It is well established that Veterans are at increased risk for mental health problems and associated hospitalization. While hospitalization is appropriate for acute stabilization, prolonged stays can contribute to reduced quality of life, increased healthcare expenditures, and trauma exposure with associated trauma-related symptoms. To reduce inpatient psychiatric length of stay and to improve patient outcomes, it is imperative that risk factors for prolonged length of stay are elucidated. The purpose of this retrospective chart review was to examine demographic and clinical characteristics and their association with inpatient psychiatric length of stay in a sample of Veterans. Demographic information collected included age and race. Clinical characteristics collected included primary admitting psychiatric diagnosis, number of psychiatric emergencies during hospitalization, utilization of restraint or seclusion, observation status, 30-day readmission status, adherence to psychiatric follow-up appointments post-discharge, and presence of suicidality. A total of 820 Veterans were included in the analysis. Age, primary psychiatric diagnosis, occurrence of a psychiatric emergency, and observation status were significant predictors of length of stay (F = 24.39, p < .001). There were significant differences in the average length of stay between Veterans with substance use disorders and those with psychotic disorders (B = 0.576, p < .001). Likewise, Veterans with neurocognitive disorders also had longer lengths of stay than those without neurocognitive disorders, respectively (B = 0.014, p < .001). In summary, quality of mental health care can be improved by reducing length of stay, but additional understanding related to risk factors is first needed.

Two factors that can increase the length of hospital stay of patients with dementia

OBJECTIVES

Patients with dementia are at greater risk of a long hospital stay and this is associated with adverse outcomes. The aim of this service evaluation was to identify variables most predictive of increased length of hospital stay amongst patients with dementia.

METHODS/DESIGN

We conducted a retrospective analysis on a cross-sectional hospital dataset for the period January-December 2016. Excluding length of stay less than 24h and readmissions, the sample comprised of 1133 patients who had a dementia diagnosis on record.

RESULTS

The highest incidence rate ratio for length of stay in the dementia sample was: (a) discharge to a care home (IRR: 2.443, 95% CI 1.778-3.357), (b) falls without harm (IRR: 2.486, 95% CI 2.029-3.045).

CONCLUSIONS

Based on this dataset, we conclude that improvements made to falls prevention strategies in hospitals and discharge planning procedures can help to reduce the length of stay for patients with dementia.

Effect of COVID-19 inpatients with cognitive decline on discharge after the quarantine period: A retrospective cohort study

Background

A new SARS-CoV-2 variant, Omicron, was reported on November 14, 2021, and it altered the COVID-19 epidemic with a different peak timing by region in Japan. Residents in the Hiroshima prefecture, especially the vulnerable elderly, were threatened by this wave in advance of many other prefectures. We evaluated the effect of cognitive decline on discharge extension after the quarantine period.

Methods

Participants of this retrospective cohort study were patients who were admitted to the care unit for COVID-19 treatment at Hiroshima University Hospital between January 1, 2022, and March 1, 2022 (60 days). Our primary outcome was the extended length of stay (LOS) in the hospital after the quarantine period (10 days after onset). A negative binomial regression analysis was performed to assess the extended LOS of patients with cognitive decline, adjusting for age classification, gender, and severity of COVID-19.

Results

The total number of participants was 74. Per the level of cognitive function, there were 56 independent participants, 5 mild declines, and 13 severe declines. For the negative binomial regression analysis, the exponentiated coefficient of mild cognitive decline was 3.05 (95% confidential interval [CI]: 1.43-6.49) and that of severe cognitive decline was 1.95 (95% CI: 1.09-3.53).

Conclusions

Mild cognitive decline and severe cognitive decline elevated the risk of extended LOS after COVID-19 patients finished the quarantine period.

Nurses' perceptions in caring for people with dementia in Dutch acute hospitals

AIMS AND OBJECTIVES

Overall, this study aimed to describe nursing care for patients with dementia in acute hospitals, with the objectives of describing the provided nursing care (a), nurses' attitudes and perceptions in caring for patients with dementia (b), and exploring how nurses deal with challenging behaviour (c). Additionally, we determined background variables associated with caring for people with dementia.

BACKGROUND

Due to comorbidities, people with dementia are frequently admitted to acute care hospitals. Here, they are at high risk of complications. Nurses strive for good care but regularly experience insufficient knowledge and skills regarding caring for people with dementia.

DESIGN

A cross-sectional survey study design.

METHODS

Data were collected in seven Dutch acute hospitals and through social media. In total, 229 hospital nurses completed the questionnaire. We used the Geriatric In-Hospital Nursing Care Questionnaire and two subscales of Hynninen on managing challenging behaviour. This report followed the STROBE checklist.

RESULTS

Nurses express that they often apply general preventive interventions not explicitly related to dementia care. In general, nurses have mixed feelings about the nursing care provided in their department. For challenging behaviour, a variety of approaches, including restrictive measures and medication, is applied. The nurses' attitudes and perceptions are influenced by the type of hospital where the nurses work, the level of education, the number of hours nurses work, and if the nurses completed a course on dementia in the last year.

CONCLUSIONS

Despite a positive attitude, nurses do not have the specific knowledge and skills needed to provide proper care. Nurses who recently completed a course on dementia had more positive attitudes and perceptions towards caring for patients with dementia.

RELEVANCE TO CLINICAL PRACTICE

The results of this research can be used to improve the quality of nursing care for patients with dementia in acute hospitals.

Creating 'Partnership in iSupport program' to optimise family carers' impact on dementia care: a randomised controlled trial protocol

Background

The majority of people with dementia are cared for by their family members. However, family carers are often unprepared for their caring roles, receiving less education and support compared with professional carers. The consequences are their reduced mental and physical health and wellbeing, and that of care recipients. This study protocol introduces the ‘Partnership in iSupport program’ that includes five interventional components: managing transitions, managing dementia progression, psychoeducation, carer support group and feedback on services. This health services research is built on family carer and dementia care service provider partnerships. The aims of the study are to evaluate the effectiveness, cost-effectiveness and family carers’ experiences in the program.

Methods

A multicentre randomised controlled trial will be conducted with family carers of people living with dementia from two tertiary hospitals and two community aged care providers across three Australian states. The estimated sample size is 185 family carers. They will be randomly assigned to either the intervention group or the usual care group. Outcomes are measurable improvements in quality of life for carers and people with dementia, caregiving self-efficacy, social support, dementia related symptoms, and health service use for carers and their care recipients. Data will be collected at three time points: baseline, 6 months and 12 months post-initiation of the intervention.

Discussion

This is the first large randomised controlled trial of a complex intervention on health and social care services with carers of people living with dementia in real-world practice across hospital and community aged care settings in three Australian states to ascertain the effectiveness, cost-effectiveness and carers’ experiences of the innovative program. We expect that this study will address gaps in supporting dementia carers in health and social care systems while generating new knowledge of the mechanisms of change in the systems. Findings will strengthen proactive health management for both people living with dementia and their carers by embedding, scaling up and sustaining the ‘Partnership in iSupport program’ in the health and social care systems.

Extended length of stay and related costs associated with dementia in acute care hospitals in Ireland

OBJECTIVE

To estimate the additional impact of dementia on in-patient length of stay (LOS) and related costs in Irish acute hospitals. Both principal and secondary diagnosis effects are estimated and valued.

METHODS

This is a cross-sectional study based on administrative data collected on all public hospital in-patient discharges in Ireland for people aged 65 years and older in 2019. Coarsened exact matching (CEM) was undertaken to account for observed confounders between dementia and non-dementia groups, while generalised linear modelling (GLM) was used to compare differences in LOS.

RESULTS

Patients with a principal diagnosis of dementia spent on average 17.5 (CI: 15.42, 19.56; p < .01) d longer in hospital than similar patients with no principal diagnosis of dementia. LOS was 6.7 (CI: 6.31, 7.14; p < .01) d longer for patients with a secondary diagnosis of dementia compared to similar patients with no secondary diagnosis of dementia. The additional annual cost of care for patients in hospitals with a secondary (principal) diagnosis of dementia was €62.0 million (€13.2 million).

CONCLUSIONS

This study highlights the economic impact of extended LOS for patients with dementia in Irish acute hospitals. Addressing specific dementia-related needs of people in hospital is likely to optimise resource use and decrease health care costs in acute care settings.

Development of a multi-component intervention to promote sleep in older persons with dementia transitioning from hospital to home

BACKGROUND

Hospitalised older persons with dementia are commonly discharged with intensified sleep disturbances. These disturbances can impede the recovery process. Nurses are well-positioned to assist persons with dementia and their family caregivers in managing sleep disturbances during the transition from hospital to home.

OBJECTIVES

To describe the development of a multi-component intervention to promote sleep.

METHODS

We applied three stages of the intervention mapping method to develop a non-pharmacological, multi-component sleep intervention. The first stage involved a review of the literature to generate an understanding of the determinants of sleep disturbances experienced by persons with dementia in hospital and home settings. The second stage consisted of a literature review to identify therapies for managing commonly reported determinants of sleep disturbances. The third stage entailed delineation of the intervention components.

RESULTS

The most common determinants of sleep disturbances experienced by persons with dementia in hospital and home settings were: physiological changes associated with ageing, sleep environments non-conducive to sleep, limited exposure to light and engagement in physical activity, stress and sleep-related beliefs and behaviours. Therapies found effective included: light therapy, physical activity therapy, sleep hygiene, and stimulus control therapy. These therapies were integrated into a multi-component sleep intervention to be provided using the teach-back technique, during and following hospitalisation.

DISCUSSION

Consistent with the principles of patient engagement, the multi-component sleep intervention will be evaluated for its acceptability and feasibility.

IMPLICATIONS FOR PRACTICE

The intervention has potentials to improve sleep during the transition from hospital to home.

Dementia-friendly intervention for hospitalized older adults with cognitive impairments: results of the Italian Dementia-Friendly Hospital Trial (IDENTITÀ)

Objective: To evaluate whether a short training focused on improving dementia care practices of the hospital staff was able to counteract functional loss and to decrease negative outcomes at discharge among hospitalized older adults with cognitive impairment.Method: Sixty-eight hospitalized participants aged 65 and over with cognitive impairment were included in the study, allocated in the control group (n = 34) and intervention group (n = 34). The intervention consisted of a short training of the hospital staff aimed at improving the management of patients with cognitive impairment. Participants were evaluated within 48 h of hospital admission and at discharge using a battery of tests including Barthel Index, Mini-Mental State Examination, and Hospital Anxiety and Depression Scale.Results: The intervention group demonstrated shorter hospital length of stay and a maintenance of the functional status at discharge compared to the control group. We observed no differences in cognitive ability between the two groups, and a trend towards a decrease of anxious symptoms in the intervention group compared to the control group.Conclusion: The results suggest that an intervention, focused on improving dementia care practices in healthcare staff, has the potential to improve the outcomes for hospitalized older adults with cognitive impairment.

Impact of Coexisting Dementia on Inpatient Outcomes for Patients Admitted with a COPD Exacerbation

Purpose

People with COPD are at a higher risk of cognitive dysfunction than the general population. However, the additional impact of dementia amongst such patients is not well understood, particularly in those admitted with a COPD exacerbation. We assessed the impact of coexisting dementia on inpatient mortality and length of stay (LOS) in patients admitted to hospital with a COPD exacerbation, using the United States based National Inpatient Sample database.

Patients and Methods

Patients aged over 40 years and hospitalised with a primary diagnosis of COPD exacerbation from 2011 to 2015 were included. Cases were grouped into patients with and without dementia. Multivariable logistic regression analysis, stratified by age, was used to assess risk of inpatient deaths. Cox regression was carried out to compare death rates and competing risk analysis gave estimates of discharge rates with time to death a competing variable.

Results

A total of 576,381 patients were included into the analysis, of which 35,372 (6.1%) had co-existent dementia. There were 6413 (1.1%) deaths recorded. The odds of inpatient death were significantly greater in younger patients with dementia (41–64 years) [OR (95% CI) dementia vs without: 1.75 (1.04–2.92), p=0.03]. Cases with dementia also had a higher inpatient mortality rate in the first 4 days [HR (95% CI) dementia vs without: 1.23 (1.08–1.41), p=0.002] and a longer LOS [sub-hazard ratio (95% CI) dementia vs without: 0.93 (0.92–0.94), p<0.001].

Conclusion

Dementia as a comorbidity is associated with worse outcomes based on inpatient deaths and LOS in patients admitted with COPD exacerbations.

The association of dementia on perioperative complications following primary total hip arthroplasty for femoral neck fractures

INTRODUCTION

Studies evaluating the association of dementia in patients undergoing total hip arthroplasty (THA) for femoral neck fractures are limited. The aim was to investigate whether patients who have dementia undergoing THA for femoral neck fractures have higher rates of (1) in-hospital lengths of stay (LOS); 2) complications (medical and prostheses-related); and 3) healthcare expenditures.

METHODS

A retrospective query using the PearlDiver database from January 1st, 2005 to March 31st, 2014 to identify patients with dementia undergoing primary total hip arthroplasty for the treatment of femoral neck fractures was performed. Dementia patients were 1:5 ratio matched to controls which yielded 22,758 patients in the study with (n = 3,798) and without (n = 18,960) dementia. Primary outcomes included comparing LOS, complications, and costs. A logistic regression was constructed to calculate the odds-ratios (OR) of dementia on complications. A p-value less than 0.004 was significant.

RESULTS

Dementia patients had longer LOS (7-days vs. 6-days, p < 0.0001) and higher incidence and odds of medical complications (41.52 vs. 17.77%; OR 3.76, p < 0.0001), including cerebrovascular events (5.66 vs. 1.64%; OR 2.35, p < 0.0001), pneumoniae (9.98 vs. 3.82%; OR 1.82, p < 0.0001), and acute kidney injury (8.37 vs. 3.27%; OR 1.62, p < 0.0001). Study group patients had higher frequency of prostheses-related complications (9.53 vs. 8.31%; OR: 1.16, p = 0.012). The study group had greater total healthcare expenditures ($28,879.57 vs. $26,234.10, p < 0.0001) when analyzing ninety-day episode of care charges.

CONCLUSION

Patients with dementia undergoing THA due to femoral neck fracture have increased LOS, medical and prostheses-related complications, and cost of care compared to their counterparts.

Dementia diagnosis in the hospital and outcomes among patients with advanced dementia documented in the Minimum Data Set

BACKGROUND

Individuals with dementia do not always have a diagnosis of dementia noted on their hospital claims. Whether this lack of documentation is associated with patient outcomes is unknown. We examined the association between a dementia diagnosis listed on a hospital claim and patient outcomes among individuals with a Minimum Data Set (MDS) assessment.

METHODS

A retrospective cohort study was conducted using administrative claims data and nursing home MDS assessments. Hospitalized patients aged 66 and older with advanced dementia noted on an MDS assessment completed within 120 days prior to their first hospitalization in 2017 were included. Advanced dementia was defined based on an MDS diagnosis of dementia, dependency in four or more activities of daily living, and a Cognitive Function Scale score indicative of moderate to severe impairment. Multilevel regression with a random intercept at the hospital level was used to examine the relationship between documentation of dementia in inpatient hospital Medicare claims and the following patient outcomes after adjusting for patient and hospital characteristics: invasive mechanical ventilation (IMV) use, intensive care unit or coronary care unit (ICU/CCU) use, 30-day mortality, and hospital length of stay (LOS).

RESULTS

In 2017, among 120,989 patients with advanced dementia and a nursing home stay, 90.57% had a dementia diagnosis on their hospital claims. In adjusted models, documentation of a dementia diagnosis was associated with lower use of the ICU/CCU (adjusted odds ratio [AOR]: 0.78 [95% confidence interval 0.74, 0.81]), use of IMV (AOR: 0.50 [0.47, 0.54]), and 30-day mortality (AOR: 0.81 [0.77, 0.85]). Patients with a dementia diagnosis had a shorter LOS.

CONCLUSIONS

Among patients with advanced dementia, those whose dementia diagnosis was documented on their inpatient hospital Medicare claim experienced lower use of ICU/CCU, use of IMV, lower 30-day mortality, and shorter LOS than those whose diagnosis was not documented.

Performing One-Session Cognitive Stimulation to Interact with Patients with Dementia in a Hospital for Mood Improvement: A Retrospective Single-Arm Cohort Study

Developing support and an environment for patients with dementia in hospitals is important. This study aims to assess the immediate effect of one-session cognitive stimulation intervention on the mood of patients with dementia in a hospital as preliminary evidence. This study included 33 female patients. The cognitive stimulation intervention was conducted in the day room of the hospital ward by two occupational therapists. The patients participated in one or more sessions. The cognitive stimulation intervention was designed to discuss current affairs that implicitly stimulate memory, executive function, and language skills, according to the cognitive stimulation definition. Outcomes were evaluated using a two-dimensional mood scale. The primary outcome was pleasure. The before and after session scores for the first session and the average score before and after each session at multiple times were compared. The patients' pleasure showed significant improvements in both analyses. These results may indicate that one-session Cognitive stimulation intervention in a hospital effectively improves a mood of pleasure immediately. This study is the first report to provide preliminary evidence on the beneficial alterations of mood after one-session cognitive stimulation intervention for patients with dementia in hospitals. Cognitive stimulation intervention may be an effective non-pharmacotherapy for these patients.

Testing the sensitivity of two dementia knowledge instruments in dementia workforce education

BACKGROUND

The importance of dementia education in improving the care and support that people living with dementia is well established. Previous research has shown ceiling effects in pre and post educational intervention measures of dementia knowledge using Knowledge in Dementia Scale (KIDE) on post-registered health and social care staff in Scotland. The aim was to test the sensitivity of two dementia knowledge instruments, namely the (KIDE) and the Dementia Knowledge Assessment Scale (DKAS).

DESIGN

A pre and post evaluation comparison of two dementia knowledge scales.

SETTING

The tenth cohort of Scotland's National Dementia Champions Education Programme, September 2019-March 2020.

PARTICIPANTS

Post-registered Health and Social Care staff (n = 117).

METHODS

Both the DKAS and KIDE scales were administered pre and post programme delivery. Wilcoxon signed-rank tests were performed to examine T1 - T2 differences in dementia knowledge for both validated measures.

RESULTS

Ceiling effects continued to be present for the KIDE scale at T1 and T2. The DKAS responses showed a different score distribution than that achieved by the KIDE. Ceiling effects noted for KIDE at T1 were not present for the DKAS. Further, at T2, only 6% of respondents scored the maximum on the DKAS.

CONCLUSIONS

The DKAS appears to be a more useful instrument for measuring knowledge in post-registered health and social care staff; however, there was some evidence of ceiling effects post-intervention. There is a need for both scales to be tested in more educationally diverse populations, so educators and researchers can make informed decisions about the instrument's target range. Additionally, further research is needed to develop new sets of dementia knowledge items suitable for use in trained health and social care staff.

Person-Centred Dementia Care in an Acute Hospital: Experiences from Nurses Working in a Specialized Dementia Unit

BACKGROUND

Person-centred care (PCC) is synonymous with best practice in the care of persons with dementia. However, the research focus has been in long-term care settings with less attention in acute hospitals. We aimed to study the perspectives and experiences of nurses implementing PCC in an acute hospital dementia unit (Care for Acute Mentally Infirm Elders [CAMIE]).

METHOD

This was an exploratory qualitative study involving individual, face-to-face, semi-structured in-depth interviews. A purposive sample of 10 nurses participated in the interview. We employed an inductive thematic analysis approach to analyse the qualitative data.

RESULTS

The findings highlighted the positive experiences, for example, meaningful connection with patients and the challenges, for example, managing challenging behaviour in providing PCC. The initial challenges were due to a lack of prior knowledge and experience. Through formal and informal learning, the nurses built confidence and competence, and also provided support to one other. They emphasized the importance of teamwork and camaraderie in the CAMIE team but raised concerns about the negative perceptions of non-CAMIE nurses on the value of their work.

CONCLUSION

Despite the challenges, adequate knowledge and robust organizational level support are the key support for nurses to embrace PCC as their care ethos in the acute care setting.

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.

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.

Time of referral to older adult liaison psychiatry service and other factors affecting length of stay in the general hospital

OBJECTIVES

To explore the relationship between social and clinical factors with (1) Time to referral to an older adult liaison psychiatry service, and (2) Length of stay (LOS), in a sample of older adults admitted to an acute general medical hospital receiving liaison psychiatry intervention, in London, United Kingdom, over a 3-year period.

METHODS

Information on patients referred to liaison psychiatry for older adults between January 2013 and December 2015 was collected using structured forms, with clinical diagnoses determined according to International Classification of Mental Disorders-10. The association of social and clinical factors with the time taken to refer to liaison psychiatry and LOS was assessed using Cox proportional hazards regression and zero-truncated Poisson regression, respectively.

RESULTS

Compared with people who were diagnosed with depression, older adults with psychotic and alcohol use disorders had higher rates of referral to liaison psychiatry (adjusted hazard ratios [aHRs] 1.83 [95% CI: 1.30, 2.59] and aHR 1.69 [95% CI: 1.01, 2.83]) respectively. In adjusted models, LOS was increased in older adults with delusional disorders and shorter in people with alcohol use disorders, personality disorders and learning disabilities, compared to people with depressive diagnoses. Within this cohort, a new definite dementia diagnosis and longer time to refer to liaison psychiatry were both associated with a longer length of general hospital in-patient stay.

CONCLUSIONS

In older adults admitted to general medical hospitals, and needing liaison psychiatry input, timely referral may be associated with a shorter LOS.

Length of Hospital Stay for Hip Fracture and 30-Day Mortality in People With Alzheimer's Disease: A Cohort Study in Finland

Background

Persons with Alzheimer’s disease (AD) are at higher risk of hip fractures (HFs) than general older population and have worse prognosis after HF. Hospital stays after HF have shortened along time. We investigated the association between length of hospital stay after HF and mortality after discharge among persons with AD.

Method

The MEDALZ cohort includes all Finnish community dwellers who received clinically verified AD diagnosis in 2005–2011 (N = 70 718). Patients who experienced first HF after AD diagnosis in 2005‒2015 (n = 6999) were selected. Length of hospital stay for HF was measured as a sum of the consecutive days spent in hospital after HF until discharge. Outcome was defined as death within 30 days after hospital discharge.

Results

Mean of overall length of hospital stay after a HF decreased from 52.6 (SD 62.9) days in 2005 to 19.6 (SD 23.1) days in 2015. Shortest treatment decile (1‒4 days) had the highest risk of death within 30 days after discharge (adjusted hazard ratio [aHR] 2.76; 95% confidence interval [CI] 1.66–4.60) in addition to second (5‒6 days; aHR 2.52; 95% CI 1.50–4.23) and third (7‒10 days; aHR 2.22; 95% CI 1.34–3.69) deciles when compared to the sixth decile of length of stays (21‒26 days).

Conclusions

Among persons with AD, shorter length of hospital stay after HF was associated with an increased risk of death after discharge. After acute HF treatment, inpatient rehabilitation or proper care and services in home need to be organized to older persons with AD.

Understanding and improving experiences of care in hospital for people living with dementia, their carers and staff: three systematic reviews

Background

Being in hospital can be particularly confusing and challenging not only for people living with dementia, but also for their carers and the staff who care for them. Improving the experience of care for people living with dementia in hospital has been recognised as a priority.

Objectives

To understand the experience of care in hospital for people living with dementia, their carers and the staff who care for them and to assess what we know about improving the experience of care.

Review methods

We undertook three systematic reviews: (1) the experience of care in hospital, (2) the experience of interventions to improve care in hospital and (3) the effectiveness and cost-effectiveness of interventions to improve the experience of care. Reviews 1 and 2 sought primary qualitative studies and were analysed using meta-ethnography. Review 3 sought comparative studies and economic evaluations of interventions to improve experience of care. An interweaving approach to overarching synthesis was used to integrate the findings across the reviews.

Data sources

Sixteen electronic databases were searched. Forwards and backwards citation chasing, author contact and grey literature searches were undertaken. Screening of title and abstracts and full texts was performed by two reviewers independently. A quality appraisal of all included studies was undertaken.

Results

Sixty-three studies (reported in 82 papers) were included in review 1, 14 studies (reported in 16 papers) were included in review 2, and 25 studies (reported in 26 papers) were included in review 3. A synthesis of review 1 studies found that when staff were delivering more person-centred care, people living with dementia, carers and staff all experienced this as better care. The line of argument, which represents the conceptual findings as a whole, was that ‘a change of hospital culture is needed before person-centred care can become routine’. From reviews 2 and 3, there was some evidence of improvements in experience of care from activities, staff training, added capacity and inclusion of carers. In consultation with internal and external stakeholders, the findings from the three reviews and overarching synthesis were developed into 12 DEMENTIA CARE pointers for service change: key institutional and environmental practices and processes that could help improve experience of care for people living with dementia in hospital.

Limitations

Few of the studies explored experience from the perspectives of people living with dementia. The measurement of experience of care across the studies was not consistent. Methodological variability and the small number of intervention studies limited the ability to draw conclusions on effectiveness.

Conclusions

The evidence suggests that, to improve the experience of care in hospital for people living with dementia, a transformation of organisational and ward cultures is needed that supports person-centred care and values the status of dementia care. Changes need to cut across hierarchies and training systems to facilitate working patterns and interactions that enable both physical and emotional care of people living with dementia in hospital. Future research needs to identify how such changes can be implemented, and how they can be maintained in the long term. To do this, well-designed controlled studies with improved reporting of methods and intervention details to elevate the quality of available evidence and facilitate comparisons across different interventions are required.

Length of hospital stay after hip fracture and readmission rates of persons with and without Alzheimer's disease: a matched cohort study

BACKGROUND

Hospital length of stays (LOS) for incident of hip fracture are decreasing, but it is unknown if these changes have negative impacts on vulnerable older patient populations, like those with Alzheimer's disease (AD). We aimed to assess if persons with and without AD have different hospital LOS for hip fracture, and is the LOS associated with hospital readmissions.

METHODS

Utilizing register-based data for a matched cohort study nested in the Medication use and Alzheimer's disease study (MEDALZ), we collected all community-dwelling persons in Finland diagnosed with AD during 2005-2012, had incident of first hip fracture between 2005 and 2015 after AD diagnosis, and were discharged alive from an acute care hospital. Hospital LOS and hospital readmissions within 30-days and 90-days were compared between those with and without AD and risk of readmission was assessed using binary logistic regression analysis.

RESULTS

In this matched cohort study of 12,532 persons (mean age 84.6 years (95% CI: 84.5-84.7), 76.8% women), the median LOS in an acute care hospital was 1 day shorter for those with AD (median 4 days, IQR 3-7) than those without AD (median 5 days, IQR 3-7) (P < 0.001). However, the AD cohort had respectively 6 days and 5 days longer median LOS in a community hospital, and total hospital stay compared to the non-AD cohort (P < 0.001 for all comparisons). Those with AD had fewer readmissions within 30-days (10.7%) and 90-days (16.9%) compared to those without AD (13.3% 30-days and 20.7% 90-days) (P < 0.001 for all comparisons). Both cohorts had a reduced readmission risk within 30-days when the LOS in an acute care hospital was 4-14 days, compared to a LOS less than 4 days.

CONCLUSIONS

Persons with AD had shorter acute care hospital LOS, but had longer LOS in a community hospital setting compared to those without AD, which is similar to other findings when comparing total hospital LOS. These findings imply that short LOS in acute care hospitals may be associated with poor health outcomes for vulnerable older populations after hip fracture.

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.

Activity interventions to improve the experience of care in hospital for people living with dementia: a systematic review

Background

An increasingly high number of patients admitted to hospital have dementia. Hospital environments can be particularly confusing and challenging for people living with dementia (Plwd) impacting their wellbeing and the ability to optimize their care. Improving the experience of care in hospital has been recognized as a priority, and non-pharmacological interventions including activity interventions have been associated with improved wellbeing and behavioral outcomes for Plwd in other settings. This systematic review aimed at evaluating the effectiveness of activity interventions to improve experience of care for Plwd in hospital.

Methods

Systematic searches were conducted in 16 electronic databases up to October 2019. Reference lists of included studies and forward citation searching were also conducted. Quantitative studies reporting comparative data for activity interventions delivered to Plwd aiming to improve their experience of care in hospital were included. Screening for inclusion, data extraction and quality appraisal were performed independently by two reviewers with discrepancies resolved by discussion with a third where necessary. Standardized mean differences (SMDs) were calculated where possible to support narrative statements and aid interpretation.

Results

Six studies met the inclusion criteria (one randomized and five non-randomized uncontrolled studies) including 216 Plwd. Activity interventions evaluated music, art, social, psychotherapeutic, and combinations of tailored activities in relation to wellbeing outcomes. Although studies were generally underpowered, findings indicated beneficial effects of activity interventions with improved mood and engagement of Plwd while in hospital, and reduced levels of responsive behaviors. Calculated SMDs ranged from very small to large but were mostly statistically non-significant.

Conclusions

The small number of identified studies indicate that activity-based interventions implemented in hospitals may be effective in improving aspects of the care experience for Plwd. Larger well-conducted studies are needed to fully evaluate the potential of this type of non-pharmacological intervention to improve experience of care in hospital settings, and whether any benefits extend to staff wellbeing and the wider ward environment.

Healthcare utilization of Mexican-American Medicare beneficiaries with and without Alzheimer's disease and related dementias

Background

Older adults with Alzheimer’s disease and related dementias (ADRD) are high-risk to experience hospitalizations and emergency room (ER) admissions. Mexican-Americans have a high prevalence of ADRD, but there is limited information on the healthcare use of older Mexican-Americans with ADRD. We used data from a cohort of older Mexican-Americans that has been linked with Medicare files to investigate differences in hospitalizations, ER admissions, and physician visits according to ADRD diagnosis. We also identify sociodemographic, health, and functional characteristics that may contribute to differences in healthcare utilization between Mexican-American Medicare beneficiaries with and without an ADRD diagnosis.

Methods and findings

Data came from the Hispanic Established Populations for the Epidemiological Study of the Elderly that has been linked with Medicare Master Beneficiary Summary Files, Medicare Provider Analysis and Review files, Outpatient Standard Analytic files, and Carrier files. The final analytic sample included 1048 participants. Participants were followed for two years (eight quarters) after their survey interview. Generalized estimating equations were used to estimate the probability for one or more hospitalizations, ER admissions, and physician visits at each quarter. ADRD was associated with higher odds for hospitalizations (OR = 1.65, 95%CI = 1.29–2.11) and ER admissions (OR = 1.57, 95%CI = 1.23–1.94) but not physician visits (OR = 1.23, 95%CI = 0.91–1.67). The odds for hospitalizations (OR = 1.24, 95%CI = 0.97–1.60) and ER admissions (OR = 1.27, 95%CI = 1.01–1.59) were reduced after controlling for limitations in activities of daily living and comorbidities.

Conclusions

Mexican-American Medicare beneficiaries with ADRD had significantly higher odds for one or more hospitalizations and ER admissions but similar physician visits compared to beneficiaries without ADRD. Functional limitations and comorbidities contributed to the higher hospitalizations and ER admissions for older Mexican-Americans with ADRD.
