Rehabilitation strategy for hip fracture, focused on behavioral psychological symptoms of dementia for older people with cognitive impairment: A nationwide Japan rehabilitation database

Factors Associated with Improvement in Activities of Daily Living during Hospitalization: A Retrospective Study of Older Patients with Hip Fractures

BACKGROUND

In this study, we aimed to examine the changes in delirium during hospitalization of patients and its association with behavioral and psychological symptoms of dementia (BPSD), as well as improvements in activities of daily living (ADL).

METHODS

A longitudinal, retrospective cohort study was conducted involving 83 older adults (≥65 years) with hip fractures. We collected Mini-Mental State Examination (MMSE) and Functional Independence Measure-motor domain (m-FIM) assessment results from the medical charts at two time points: baseline (first week of hospitalization) and pre-discharge (final week before discharge). Additionally, we collected data on delirium and BPSD at three points: baseline, week 2 post-admission, and pre-discharge. We performed univariate logistic regression analysis using changes in m-FIM scores as the dependent variable and MMSE and m-FIM scores at baseline and pre-discharge, along with delirium and BPSD subtypes at baseline, week 2 post-admission, and pre-discharge, as the explanatory variables. Finally, we performed a multivariate logistic regression analysis incorporating the significant variables from the univariate analysis to identify factors associated with ADL improvement during hospitalization.

RESULTS

We observed significant correlations between ADL improvement during hospitalization and baseline m-FIM and MMSE scores, hypoactive delirium state, and BPSD subtype pre-discharge. Notably, all participants with hypoactive symptoms before discharge exhibited some subtype of delirium and BPSD at baseline.

CONCLUSION

Besides ADL ability and cognitive function at admission, the presence of hypoactive delirium and BPSD subtype before discharge may hinder ADL improvement during hospitalization.

Rehabilitation after Hip Fracture Surgery Improves Physical and Cognitive Function in Patients with or Without Sarcopenia

Introduction

Sarcopenia is a prevalent risk factor for falls and fractures, and it affects the physical function and mortality of older people. The present study was performed to assess the prevalence of sarcopenia in patients who underwent rehabilitation after hip fracture surgery and to examine the association of sarcopenia with physical and cognitive function outcomes.

Methods

This case-control study involved 132 patients who were admitted to a convalescent rehabilitation ward at a single hospital after surgical treatment of hip fractures from April 2018 to March 2020. The skeletal muscle mass index was examined using whole-body dual-energy X-ray absorptiometry. The Asian Working Group for Sarcopenia 2019 diagnostic criteria were applied on admission. We compared the walking speed, Mini-Mental State Examination (MMSE) score, and Functional Independence Measure (FIM) score between the sarcopenia group and non-sarcopenia group on admission and on discharge.

Results

The prevalence of sarcopenia was 59.8%. In the non-sarcopenia group, the walking speed, MMSE score, FIM total score, FIM motor score, and FIM cognitive score were significantly lower on admission than those on discharge (P < .05). In the sarcopenia group, the walking speed, MMSE score, FIM total score, and FIM motor score were significantly lower on admission than those on discharge (P < .05); there was no significant difference in the FIM cognitive score between admission and discharge. On both admission and discharge, the MMSE score, FIM total score, FIM motor score, and FIM cognitive score were significantly better in the non-sarcopenia group than those in the sarcopenia group.

Conclusions

After postoperative rehabilitation of hip fractures in patients with and without sarcopenia, physical and cognitive function outcomes on discharge were significantly better than those on admission. Patients with sarcopenia had significantly worse physical and cognitive function outcomes than patients without sarcopenia both on admission and on discharge.

Relation between number of teeth, malnutrition, and 3-year mortality in elderly individuals ≥85 years

OBJECTIVE

The number of teeth has been shown to affect mortality. However, it is unclear why the number of teeth is associated with mortality. We focused on the number of teeth and malnutrition and examined whether these differences affect 3-year all-cause mortality among very elderly individuals.

METHODS

This analysis was conducted using data from the Tokyo Oldest Old Survey on Total Health study. Altogether 513 participants ≥85 years were categorized based on remaining teeth (0, 1-7, 8-18, ≥19). All-cause mortality was determined by calculating the cumulative 3-year survival rate according to the remaining number of teeth and the presence/absence of malnutrition. Further, hazard ratios (HRs) were analyzed using Cox regression analyses.

RESULTS

No difference was observed according to the number of teeth (p = 0.638), but the presence/absence of malnutrition was significantly associated with mortality (p < 0.001). Malnutrition was independently associated with higher HRs, even after adjusting for confounding factors associated with mortality. (HR: 2.315, 95% CI: 1.431-3.746). Additionally, adjusting for the number of teeth, HR remained significant (HR: 2.365, 95% CI: 1.449-3.853).

CONCLUSION

In the very elderly, malnutrition-but not the number of teeth-was independently associated with 3-year all-cause mortality after adjusting for various health issues.

Indicators of Improvement in Performing Activities of Daily Living Among Older Patients Undergoing Rehabilitation Following Hip Fractures

This study aimed to evaluate the relationship between improvement in activities of daily living (ADL) and cognitive status during rehabilitation and assess factors associated with ADL improvement among older patients undergoing rehabilitation after hip fractures. This retrospective cohort study comprised 306 patients aged ≥80 years who underwent hip fracture rehabilitation. The functional independence measure gain during rehabilitation was significantly lower in the group with abnormal cognition than in the group with normal cognition. Mini-Mental State Examination, Charlson Comorbidity Index, daily duration of rehabilitation, and length of hospitalization for rehabilitation were independent factors associated with functional independence measure gain during rehabilitation in the multivariate regression analysis. Although older patients with cognitive impairment had lower ADL improvements during hip fracture rehabilitation, such patients may be able to improve their ADL by undergoing intensive and long rehabilitation programs. They should not refrain from such rehabilitation programs due to older age, fracture, and cognitive impairment.

What is the subtype of dementia in patients with fragility hip fracture?

Introduction

Cognitive function is an important factor that affects functional recovery after hip fracture (HipFx) surgery. The literature on the pathophysiology of dementia in HipFx patients is scarce. We performed a differential diagnosis of dementia in HipFx patients using clinical and brain MRI findings.

Methods

This is a prospective study in which brain MRI was evaluated for patients with HipFx for research purposes. One-hundred-and-five HipFx patients (85 females and 20 males) who underwent surgery and were subsequently able to undergo brain MRI at our hospital were evaluated. The mean age was 84 years. The presence of dementia was determined based on clinical findings and whether the patient meets its diagnostic criteria according to the International Classification of Diseases 10th Edition (ICD-10). The differential diagnosis of dementia was made based on brain MRI findings and the dementia diagnostic flow chart published in the Clinical Practice Guideline for Dementia 2017 (Japanese Society of Neurology). The Voxel-based Specific Regional Analysis System for Alzheimer’s Disease (VSRAD) advance 2 diagnostic software was used to evaluate atrophy of the para-hippocampal gyrus.

Results

Fifty-six (53%) patients were clinically diagnosed with dementia according to the ICD-10 criteria. The MRI findings were diverse: Alzheimer’s disease (AD)-type, asymptomatic multiple ischemic cerebral lesions, past symptomatic cerebral infarction or cerebral hemorrhage, Binswanger’s disease (BW)-type, chronic subdural hematoma, disproportionately enlarged subarachnoidal hydrocephalus (DESH), and their combinations thereof. A combination of MRI and clinical findings of dementia patients demonstrated the following distribution of dementia subtypes: AD (n = 20), vascular dementia (n = 33), AD and BW vascular dementia (n = 3).

Conclusion

This study revealed that the brain MRI findings of HipFx patients were diverse. Although vascular dementia is found to be common in this particular population, this could be an incidental finding. Further study is warranted to clarify the specificity of our findings by increasing the number of patients, setting the control, and investigating whether dementia subtypes affect postoperative gait acquisition and fall risk.

Influence of Cognitive Impairment on Rehabilitation Received and Its Mediating Effect on Functional Recovery

BACKGROUND

Cognitive impairment (CI) has been reported to negatively impact rehabilitation outcomes. Knowledge about differences in rehabilitation received in dependence of CI as a potential mediating factor is limited.

OBJECTIVE

To analyze whether CI affects amount and frequency of rehabilitation received and if associations between CI and rehabilitation outcome are mediated by the provided amount of therapy.

METHODS

Observational cohort study in ward-based geriatric rehabilitation consecutively including 373 patients (mean age 82.0±6.69 years, mean MMSE 23.66±5.31). Outcome measures were amount, frequency, and type of multi-professional therapy sessions and rehabilitation outcome assessed with the Barthel Index (BI). Cognitive status was measured with the Mini-Mental-State Examination (MMSE) classifying three patient subgroups according to cognitive status.

RESULTS

Patients with more severe CI received least total therapy hours (TTH) (MMSE < 17, 13.67±6.58 versus MMSE 17-26, 16.12±7.19 and MMSE > 26, 17.79±8.88 h, p = 0.014) and were less often included in occupational therapy (MMSE < 17, 48.9%versus MMSE 17-26, 65.5%and MMSE > 26, 71.4%, p = 0.019) and group-based physiotherapy (MMSE < 17, 73.3%versus MMSE 17-26, 88.5%and MMSE > 26, 81.2%, p = 0.027). Regression models showed that CI negatively impacted TTH (β= 0.24, p = 0.003) and rehabilitation outcome (β= 0.41, p = 0.008). In the mediation model, TTH accounted for 23.18%(p < 0.001) of the relationship between CI and rehabilitation outcome.

CONCLUSION

Cognitive impairment negatively impacted rehabilitation received. The lower TTH partly mediated the negative association between CI and rehabilitation outcome. Future research should identify specific barriers to therapy provision and optimal length, intensity, and dosage of rehabilitation programs to optimize rehabilitation outcomes in CI.

Sex Differences in Recovery Across Multiple Domains Among Older Adults With Hip Fracture

BACKGROUND

Hip fractures are a public health problem among older adults, but most research on recovery after hip fracture has been limited to females. With growing numbers of hip fractures among males, it is important to determine how recovery outcomes may differ between the sexes.

METHODS

168 males and 171 females were enrolled within 15 days of hospitalization with follow-up visits at 2, 6, and 12 months postadmission to assess changes in disability, physical performance, cognition, depressive symptoms, body composition, and strength, and all-cause mortality. Generalized estimating equations examined whether males and females followed identical outcome recovery assessed by the change in each outcome.

RESULTS

The mean age at fracture was similar for males (80.4) and females (81.4), and males had more comorbidities (2.5 vs 1.6) than females. Males were significantly more likely to die over 12 months (hazard ratio 2.89, 95% confidence interval: 1.56-5.34). Changes in outcomes were significantly different between males and females for disability, gait speed, and depressive symptoms (p < .05). Both sexes improved from baseline to 6 months for these measures, but only males continued to improve between 6 and 12 months. There were baseline differences for most body composition measures and strength; however, there were no significant differences in change by sex.

CONCLUSIONS

Findings confirm that males have higher mortality but suggest that male survivors have continued functional recovery over the 12 months compared to females. Research is needed to determine the underlying causes of these sex differences for developing future prognostic information and rehabilitative interventions.

Environmental factors related to sleep latency among inpatients in rehabilitation wards according to functional independence measure cognitive scores

BACKGROUND

No study has investigated sleep-related environmental factors in patients according to their functional independence measure (FIM) cognitive scores.

AIMS

The aim of this study is to examine the associations between environmental factors such as noise and sleep latency according to the FIM cognitive scores among inpatients in rehabilitation wards.

DESIGN

This is a prospective longitudinal study.

METHODS

This study measured the sleep state using a bed-based actigraphy, environmental data from Environmental Sensor®, and medical record information of 33 inpatients in the rehabilitation wards during 2018. A linear mixed-effect model was used to analyse the associations between sleep latency and environmental factors. Participants were grouped according to high or low FIM cognitive scores.

RESULTS

The average patient age was 77.2 ± 10.9 years, and 48.5% were male. In the high FIM cognitive score group, the loudness and frequency of noise exceeding 40 dB during sleep latency were significantly associated with sleep latency. In the low FIM cognitive score group, only the noise frequency was associated with sleep latency, and intra-individual variance was larger than that of the high group.

CONCLUSION

These findings suggest that providing night care with attention to subdued noise is important, particularly for patients with low cognitive functional independence levels measured by the FIM cognitive score.

Orthogeriatric Management: Improvements in Outcomes during Hospital Admission Due to Hip Fracture

Hip fractures are an important socio-economic problem in western countries. Over the past 60 years orthogeriatric care has improved the management of older patients admitted to hospital after suffering hip fractures. Quality of care in orthogeriatric co-management units has increased, reducing adverse events during acute admission, length of stay, both in-hospital and mid-term mortality, as well as healthcare and social costs. Nevertheless, a large number of areas of controversy regarding the clinical management of older adults admitted due to hip fracture remain to be clarified. This narrative review, centered in the last 5 years, combined the search terms "hip fracture", "geriatric assessment", "second hip fracture", "surgery", "perioperative management" and "orthogeriatric care", in order to summarise the state of the art of some questions such as the optimum analgesic protocol, the best approach for treating anemia, the surgical options recommendable for each type of fracture and the efficiency of orthogeriatric co-management and functional recovery.

Potential prescribing omissions of anti-osteoporosis drugs is associated with rehabilitation outcomes after fragility fracture: Retrospective cohort study

AIM

We investigated the association between rehabilitation outcomes and polypharmacy, potentially inappropriate medications and potential prescribing omissions in older adults with fragility fractures.

METHODS

In total, we registered 217 older adults with fragility fractures (hip or vertebral) retrospectively and examined the association between rehabilitation outcome and polypharmacy, potentially inappropriate medications and potential prescribing omissions. Polypharmacy was defined as five or more drugs. Potentially inappropriate medications and potential prescribing omissions were defined by the Beers criteria (2015) and the screening tool to alert to treatment criteria version 2, respectively. The outcome was functional independence measure gain (functional independence measure at discharge - functional independence measure at admission).

RESULTS

Multiple regression analyses revealed no association between functional independence measure gain and polypharmacy (crude: β = 0.058, P = 0.858; adjusted model: β = 0.013, P = 0.869) or potentially inappropriate medications (crude: β = 0.100, P = 0.144; adjusted model: β = 0.084, P = 0.260). However, there was a significant association between functional independence measure gain and potential prescribing omissions (crude: β = 0.167, P = 0.014; adjusted model: β = 0.180, P = 0.016). Participants without potential prescribing omissions (in other words, participants who were prescribed anti-osteoporosis drugs) had a greater functional independence measure gain than participants with potential prescribing omissions (in other words, those that were not prescribed anti-osteoporosis drugs).

CONCLUSION

To the best of our knowledge, this study is the first to report that participants without potential prescribing omissions had significantly improved rehabilitation outcomes. Geriatr Gerontol Int 2021; 21: 386-391.

Prevalence of depression in older people with hip fracture: A systematic review and meta-analysis

INTRODUCTION

Hip fracture disrupts general health and is one of the most common physical injuries in the elderly. Depression is the most common mood disorder in older people and one of the main complications of hip fractures.

AIM AND METHODS

We conducted a meta-analysis to estimate the prevalence of depression in older people with hip fractures. Relevant literature published until July 2019 was obtained and screened according to established inclusion criteria. Two researchers independently carried out quality assessment and data extraction before the meta-analysis. We calculated proportions with 95% confidence intervals (CI). To investigate the sources of heterogeneity, we performed subgroup analyses based on study design, follow-up duration, type of fracture, and gender.

RESULTS

Twenty-seven studies with a combined sample size of 11958 were included. The overall prevalence of depression in older people with hip fracture was 23% (95% CI: 0.18 to 0.29). The lowest and highest prevalence of depression was in Asia (0.19) and America (0.27) respectively.

CONCLUSION

In this systematic review and meta-analysis the estimated prevalence of depression among older hip fracture patients was 23%. Further research is needed to identify strategies for preventing and treating mood disorders in this population.

Socioeconomic and clinical risk factors of hip fracture among the elderly: a case-control study

Background/Aims

The aim of the study was to investigate the socioeconomic and clinical risk factors for hip fracture among a community-dwelling elderly population in Greece. It also aimed to identify characteristics associated with reducing mobility.

Methods

A case-control study was conducted on 202 patients who had a hip fracture and on 202 other members of the elderly population who did not have a hip fracture as the control group.

Results

In the multivariate analysis, the variables related to an increased risk of hip fracture were: gender (odds ration [OR]=10.88; 95%confidence Interval [CI]=2.28–51.98), income (OR=32.50; 95%CI=2.96–356.43), income adequacy (OR=129,34; 95%CI=7,09–2360,88), inability to pay expenses/medication (OR=0.02; 95%CI=0.003–0.09), depression (OR=0.03; 95%CI=0.002–0.35), multimorbidity (OR=0.01; 95%CI=0.001–0.97), number of medication (OR=0.02; 95%CI=0.001–0.28) and history of falls (OR=0.08; 95%CI=0.01–0.40). Factors related to deterioration of mobility were: age (OR=28.43; 95%CI:5.45–148.32), dementia (OR=15.60; 95%CI:1.80–135.27), walking ability (OR=0.20; 95%CI:0.07–0.56), balance (OR=9.10; 95%CI:1.89–43.75), use of walking aid (OR=7.42; 95%CI:2.70–20.39), and length of hospitalisation (OR=3.01; 95%CI:1.27–7.14).

Conclusions

Socioeconomic and clinical factors that lead to an increased risk of hip fracture were identified, as well as factors affecting post-operative functional ability that could guide prevention programmes.
