Evaluating hospital care for individuals with Alzheimer's disease using inpatient quality indicators

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

Dementia and Hip Fractures: A Comprehensive Review of Management Approaches

» The elderly population is the fastest growing demographic, and the number of dementia cases in the United States is expected to double to 10 million by 2050.» Patients with dementia are at 3× higher risk of hip fractures and have higher morbidity and mortality after hip fractures.» Hip fracture patients with dementia benefit from early analgesia and timely surgical fixation of fracture.» Early and intensive inpatient rehabilitation is associated with improved postoperative outcomes in patients with dementia.» Coordination of care within a "orthogeriatric" team decreases mortality, and fracture liaison services show potential for improving long-term outcomes in hip fracture patients with dementia.

Mortality and Discharge Location of Intensive Care Patients With Alzheimer Disease and Related Dementia

BACKGROUND

Intensive care unit (ICU) utilization has increased among patients with Alzheimer disease and related dementia (ADRD), although outcomes are poor.

OBJECTIVES

To compare ICU discharge location and subsequent mortality between patients with and patients without ADRD enrolled in Medicare Advantage.

METHODS

This observational study used Optum's Clinformatics Data Mart Database from years 2016 to 2019 and included adults aged >67 years with continuous Medicare Advantage coverage and a first ICU admission in 2018. Alzheimer disease and related dementia and comorbid conditions were identified from claims. Outcomes included discharge location (home vs other facilities) and mortality (within the same calendar month of discharge and within 12 months after discharge).

RESULTS

A total of 145 342 adults met inclusion criteria; 10.5% had ADRD and were likely to be older, female, and have more comorbid conditions. Only 37.6% of patients with ADRD were discharged home versus 68.6% of patients who did not have ADRD (odds ratio [OR], 0.40; 95% CI, 0.38-0.41). Both death in the same month as discharge (19.9% vs 10.3%; OR, 1.54; 95% CI, 1.47-1.62) and death in the 12 months after discharge (50.8% vs 26.2%; OR, 1.95; 95% CI, 1.88-2.02) were twice as common among patients with ADRD.

CONCLUSIONS

Patients with ADRD have lower home discharge rates and greater mortality after an ICU stay than patients without ADRD.

Patients Lacking the Capacity to Consent to Hip Fracture Surgery May Be Undergoing Major Operations Without Their Next of Kin Being Involved in Best-Interests Decisions: A Quality Improvement Report

Background Cognitively impaired patients with a hip fracture may be undergoing major operations without attempts being made to involve their next of kin (NoK) in best-interest decisions. Methods We used the Plan-Do-Study-Act (PDSA) methodology to guide our quality improvement (QI) project. Cognitively impaired hip fracture patients were identified retrospectively by searching the hip fracture database of a medium-sized district general hospital (DGH). Their medical notes were reviewed for documented attempts at contacting their NoK prior to surgery as well as on completion of the NoK section of the Consent Form Four. Intervention A simple feedback intervention was delivered in the form of a mixed verbal and visual presentation to the orthopaedic registrars responsible for obtaining consent from these patients. Results Post-intervention, there were documented attempts at contacting the NoK before surgery for all patients, a significant improvement from only 80%. There was also a significant increase in completion of the NoK section of the consent form, from 30% to 64.3%. Conclusions Simple audit and feedback interventions can produce significant positive changes in communication between clinicians and the NoK of cognitively impaired patients with hip fractures. Further interventions have been implemented to sustain these improvements.

Dementia and the Critically Ill Older Adult

Dementia is a terminal illness that leads to progressive cognitive and functional decline. As the elderly population grows, the incidence of dementia in hospitalized older adults increases and is associated with poor short-term and long-term outcomes. Delirium is associated with an accelerated cognitive decline in hospitalized patients with dementia. The first step in the management of dementia is accurate and early diagnosis. Evidence-based management guidelines in the setting of critical illness and dementia are lacking. The cornerstone of management is defining goals of care early in the course of hospitalization and using palliative care and hospice when deemed appropriate.

Risk factors for in-hospital mortality in patients with dementia

OBJECTIVE

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

STUDY DESIGN

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

MAIN OUTCOME MEASURES

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

RESULTS

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

CONCLUSIONS

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

Pneumonia-associated death in patients with dementia: A systematic review and meta-analysis

BACKGROUND

Pneumonia is a serious disease associated with mortality among patients with dementia. However, the reported frequency of pneumonia as a cause of death in patients with dementia varies, the reason for which has not been fully elucidated.

METHODS

We conducted a systematic search in PubMed and the Cochrane Database of Systematic Reviews (inception to December 2016). Two authors independently determined the suitability of studies and potential bias and extracted the data. The primary outcome was frequency of pneumonia-associated death in patients with dementia. Stratified subgroup analysis was conducted among studies grouped according to type of mortality cause (immediate or underlying), information source of mortality cause (autopsy or death certificate), and study setting (clinic, hospital, or nursing home).

RESULTS

We included 7 studies reporting the cause of death among patients with dementia and 12 studies comparing the cause of death among patients with and without dementia. The frequency of pneumonia-associated death among 19 eligible studies was 29.69% (95% confidence interval [CI], 25.86-33.53). Those frequencies differed according to whether the source for information about cause of death was an autopsy confirmation (49.98%; 95% CI, 43.75-56.71) or death certificate (19.65%; 95% CI, 15.48-23.83) and according to whether the type of mortality cause was an indirect cause of death (13.96%; 95% CI, 9.42-18.51) or direct cause of death (44.45%; 95% CI, 29.81-50.10). The risk of pneumonia-associated death in patients with dementia was twice as high as among those without dementia (odds ratio, 2.15; 95% CI, 1.63-2.83; p < 0.001).

CONCLUSION

The various frequencies of pneumonia-associated death in patients with dementia were associated with the information source, type of mortality cause, and study setting. Patients with dementia in the terminal stages urgently require careful clinical management of pneumonia, to maximize patient life expectancy and quality.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Freedom of Information Act: scalpel or just a sharp knife?

The concluding statement of the Burns Commission, established to evaluate whether changes are needed to the Freedom of Information Act (FOIA), ruled no major legislative changes were required. As such Freedom of Information (FOI) legislation still enables anyone to obtain information from public authorities. In this brief report article we explore arguments regarding FOI as an instrument for healthcare research using an international research programme as a case study.

Hip fractures and dementia: clinical decisions for the future

Severe dementia is a life-limiting condition; hip fractures are more common in patients who have dementia. This study outlines the case of a 92-year-old female with severe dementia who sustained a hip fracture. Despite having a terminal diagnosis (severe dementia and hip fracture) and poor premorbid quality of life, she had a life-prolonging surgery. The report outlines issues around treatment options in such circumstances, informed consent and substitute decision-making. The authors propose a 'goals of care' approach to manage patients in whom the best treatment is unclear, during their attendance to the emergency department. It is suggested that utilization of such a model may help with substitute decision-making and true informed consent.

Predictors of Gaps in Patient Safety and Quality in U.S. Hospitals

OBJECTIVE

To explore predictors of gaps between observed and best possible Hospital Compare scores in U.S. hospitals.

DATA SOURCES

American Hospital Association Annual Survey; Area Resource Files; Centers for Medicare and Medicaid Services Medicare Provider and Analysis Review; and Hospital Compare data.

STUDY DESIGN

Using Stochastic Frontier Analysis and secondary cross-sectional data, gaps between the best possible and actual scores of Hospital Compare quality measures were estimated. Poisson regressions were used to ascertain financial, organizational, and market predictors of those gaps.

DATA EXTRACTION

Data were cleaned and matched based on hospital Medicare IDs. All U.S. hospitals that matched on analysis variables in 2007 were in the study (1,823-2,747, depending upon gap variable).

PRINCIPAL FINDINGS

Most hospitals have a greater than 10 percent gap in quality indicators. Payer mix, registered nurse staffing, size, case mix index, accreditation, being a teaching hospital, market competition, urban location, and region were strong predictors of gaps, although the direction of the association with gaps was not uniform across outcomes.

CONCLUSIONS

A significant percentage of hospitals have gaps between their best possible and observed quality scores. It may be better to use gap scores than observed scores in payments systems. More SFA research is needed to know how to lower gaps through changes in hospital and market characteristics.

A systematic review and meta-analysis examining pneumonia-associated mortality in dementia

BACKGROUND

Although it is generally accepted that deaths associated with pneumonia are more common in patients with dementia, no comprehensive reviews on the subject have previously been published.

SUMMARY

Relevant studies were identified through a literature search of the PubMed, EMBASE, Scopus, and ISI Web of Science databases for publications up to August 2013. Studies were included if (1) a group of adult subjects with dementia and a (comparison) group composed of subjects without dementia were included, (2) the cause(s) of death was/were reported, and (3) pneumonia was identified as one of the possible causes of death. The occurrence of death due to pneumonia associated with dementia was expressed as an odds ratio (OR) with 95% confidence interval (CI). Thirteen studies were included. The odds of death resulting from pneumonia were significantly increased for persons with any form of dementia compared with those without dementia (OR = 2.22, 95% CI 1.44-3.42, p < 0.001). In a subgroup analysis, using the results from 8 studies that restricted inclusion to persons with Alzheimer's disease, the odds of death resulting from pneumonia were also significantly higher (OR = 1.70, 95% CI 1.12-2.58, p = 0.013). Key Messages: The odds of pneumonia-associated mortality were increased more than 2-fold for patients with dementia.

Health care experiences of people with dementia and their caregivers: a meta-ethnographic analysis of qualitative studies

BACKGROUND

Understanding the health care experience of people with dementia and their caregivers is becoming increasingly important given the growing number of affected individuals. We conducted a systematic review of qualitative studies that examined aspects of the health care experience of people with dementia and their caregivers to better understand ways to improve care for this population.

METHODS

We searched the electronic databases MEDLINE, Embase, PsychINFO and CINAHL to identify relevant articles. We extracted key study characteristics and methods from the included studies. We also extracted direct quotes from the primary studies, along with the interpretations provided by authors of the studies. We used meta-ethnography to synthesize the extracted information into an overall framework. We evaluated the quality of the primary studies using the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist.

RESULTS

In total, 46 studies met our inclusion criteria; these involved 1866 people with dementia and their caregivers. We identified 5 major themes: seeking a diagnosis; accessing supports and services; addressing information needs; disease management; and communication and attitudes of health care providers. We conceptualized the health care experience as progressing through phases of seeking understanding and information, identifying the problem, role transitions following diagnosis and living with change.

INTERPRETATION

The health care experience of people with dementia and their caregivers is a complex and dynamic process, which could be improved for many people. Understanding these experiences provides insight into potential gaps in existing health services. Modifying existing services or implementing new models of care to address these gaps may lead to improved outcomes for people with dementia and their caregivers.

Prevention and clinical management of hip fractures in patients with dementia

Hip fractures and dementia increase exponentially with age, and patients who are afflicted by both conditions suffer significant morbidity and mortality. The aging of our population heightens the need to recognize the interaction of these conditions in order to improve our efforts to prevent hip fractures, provide acute care that improves outcomes, and provide secondary prevention and rehabilitation that returns patients to their previous level of functioning. Identification and treatment of vitamin D deficiency and osteoporosis and assessment and interventions to reduce falls in patients with dementia can significantly impact the incidence of first and subsequent hip fractures. Acute management of hip fractures that focuses on comanagement by orthopedic surgeons and geriatricians and uses protocol-driven geriatric-focused care has been shown to decrease mortality, length of hospitalization, readmission rates, and complications including delirium. Patients with mild-to-moderate dementia benefit from intensive geriatric rehabilitation to avoid nursing home placement. Recognizing the need to optimize primary and secondary prevention of hip fractures in patients with dementia and educating providers and families will lead to improved quality of life for patients affected by dementia and hip fractures.

Improving hip fracture care: striving for excellence

Hip fracture is a common and potentially devastating injury that occurs mainly in older people. The incidence is predicted to rise by 30% in the next 10 years alone. Many of those who recover suffer a loss of mobility and independence. There is growing emphasis to improve the care of patients sustaining hip fracture, especially in those with concurrent cognitive impairment. This review focuses on current best practice as well as several key areas of management, including analgesia, anaemia and nutrition. In doing so, we hope to identify interventions that may form the basis of a future Enhanced Recovery Pathway dedicated to hip fracture care.

Dementia increases the risks of acute organ dysfunction, severe sepsis and mortality in hospitalized older patients: a national population-based study

Background

Dementia increases the risk of death in older patients hospitalized for acute illnesses. However, the effect of dementia on the risks of developing acute organ dysfunction and severe sepsis as well as on the risk of hospital mortality in hospitalized older patients remains unknown, especially when treatments for these life-threatening situations are considered.

Methods

In this population-based cohort study, we analyzed 41,672 older (≥65 years) patients, including 3,487 (8.4%) with dementia, from the first-time admission claim data between 2005 and 2007 for a nationally representative sample of one million beneficiaries enrolled in the Taiwan National Health Insurance Research Database. Outcomes included acute organ dysfunction, severe sepsis, and hospital mortality. The effect of dementia on outcomes was assessed using multivariable logistic regression.

Results

Dementia was associated with a 32% higher risk of acute organ dysfunction (adjusted odds ratio [aOR] 1.32, 95% confidence interval [CI] 1.19–1.46), a 50% higher risk of severe sepsis (aOR 1.50, 95% CI 1.32–1.69) and a 28% higher risk of hospital mortality (aOR 1.28, 95% CI 1.10–1.48) after controlling age, sex, surgical condition, comorbidity, principal diagnosis, infection status, hospital level, and length of hospital stay. However, the significant adverse effect of dementia on hospital mortality disappeared when life-support treatments, including vasopressor use, hemodialysis, mechanical ventilation, and intensive care, were also controlled.

Conclusions

In hospitalized older patients, the presence of dementia increased the risks of acute organ dysfunction, severe sepsis and hospital mortality. However, after intervention using life-support treatments, dementia only exhibited a minor role on short-term mortality.

Prevalence of dementia and cognitive impairment among older adults with hip fractures

BACKGROUND

Dementia and cognitive impairment are known to be risk factors for hip fractures and are associated with increased postoperative morbidity and mortality. Little is known of the prevalence of dementia and cognitive impairment among older adults with hip fractures.

METHODS

We completed searches of the electronic databases for observational studies and report the prevalence of either dementia or cognitive impairment among individuals with hip fractures. We included studies that reported the prevalence of dementia using standard diagnostic criteria or cognitive impairment as measured on cognitive screening tests. We used random-effects meta-analysis to arrive at pooled estimates of the prevalence of dementia and cognitive impairment.

RESULTS

Five studies reported the prevalence of dementia and 34 studies reported the prevalence of cognitive impairment in older adults with hip fractures. The estimated prevalence of dementia among older adults with hip fractures was 19.2% (95% confidence interval [CI]: 11.4% to 30.6%), whereas the prevalence of cognitive impairment was 41.8% (95% CI: 37.0% to 46.8%). In subgroup analyses, individuals admitted from long-term care were more likely to have dementia when compared with individuals admitted from the community, whereas there were no significant differences in the prevalence of cognitive impairment according to gender or study setting.

CONCLUSIONS

We conclude that dementia and cognitive impairment are common among older adults with hip fractures. Clinicians providing care for individuals with hip fractures should be aware of the high prevalence of cognitive impairment in this population. Effective strategies to prevent hip fractures and improve postoperative outcomes for older adults with dementia are needed.

Protecting Personhood and Achieving Quality of Life for Older Adults With Dementia in the U.S. Health Care System

Objective: As the numbers of persons diagnosed with Alzheimer's disease and related dementias increase, many questions arise pertaining to the quality of life of those diagnosed and the health care system as it relates to the provision of quality care for this population. This article examines the health disparities among older adults with dementia, emphasizing the protection of personhood and quality of life, along with a review of the barriers to health care access and utilization of persons living with dementia. Method: This literature review utilized electronic databases and other documents. Results: The findings suggest that while progress has been realized toward protecting personhood and achieving an improved quality of life among older adults with dementia in the U.S. health care system challenges still exist. Discussion: The implications of current and future public policy, avenues for further research, and strategies by which the health care community may better serve persons with dementia are outlined.
