Association of swallowing problems with frailty in Chinese hospitalized older patients

Association between dysphagia and activities of daily living in older adults: a systematic review and meta-analysis

PURPOSE

Numerous epidemiological studies have suggested a possible association between dysphagia and the risk of decline in Activities of daily living (ADL) among older adults. This systematic review and meta-analysis aimed to elucidate the relationship between dysphagia and ADL in older adults.

METHODS

PubMed, Web of Science, Cochrane Library, Embase, Ebsco, MEDLINE, Wiley, CINAHL, and Ovid databases were comprehensively examined for relevant studies published up to October 31, 2022. Quantitative studies published in English were included to explore the relationship between dysphagia and ADL in people aged 65 years and older. The NIH Quality Assessment Tool was used to assess the study quality. R software was used to draw forest plots and I2 was employed to indicate study heterogeneity. Sensitivity analysis was performed using the one-by-one exclusion method. Publication bias was measured using funnel plots and Egger's test.

RESULTS

A total of 3,498 studies were retrieved from the database, 22 of which were eventually included in the systematic evaluation, and 14 of which were subjected to meta-analysis. Data from nine studies were categorical variables, and meta-analysis results showed that swallowing disorders in older adults were associated with a lower ability to perform ADL (OR = 3.39, 95% CI: 2.55-4.50, p < 0.001), with moderate heterogeneity (I2 = 62%, p = 0.006). Data from seven studies were continuous variables, resulting in a negative association between the prevalence of dysphagia and ADLs in older adults (SMD = -0.80, 95% CI: -1.08 to -0.51, p < 0.001), with high heterogeneity (I2 = 94%, p < 0.001). Sensitivity analysis showed robust results, funnel plots and Egger's test indicated no publication bias.

CONCLUSION

Dysphagia is significantly associated with the capacity to perform ADL. Prevention and screening of dysphagia in older patients dependent on others for daily care are needed. Further long-term studies are needed in the future to prove causality.

The prevalence of presbyphagia in older adults: a systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

Presbyphagia is defined as structural, physiological and innervational alterations in the swallowing process as a result of aging and is considered to be involved in the etiology of dysphagia. This systematic review and meta-analysis aimed to estimate the prevalence of presbyphagia in older adults without disease-related dysphagia.

METHODS

In this study five databases were searched in October 2023 with no time limitation. Combined effect sizes of presbyphagia prevalence were calculated using random effect models. Meta-regression and subgroup analyses were conducted to identify sources of heterogeneity. Egger's test and a funnel plot were employed to examine publication bias.

RESULTS

A total of 19 studies were selected for analysis. Overall, the prevalence of presbyphagia in older adults was 30.8% (95% confidence interval [CI] 24.8-36.7%). Publication bias was adjusted for using the fill-and-trim method and the corrected pooled prevalence of presbyphagia was 17.3% (95% CI 11.0-23.6%). In addition, the meta-regression findings revealed that the assessment tool had significant effects upon heterogeneity.

CONCLUSION

Although the pooled prevalence of presbyphagia in older adults was 17.3%, the lack of large representative studies limited the interpretation of these findings. In the future, further large studies that diagnose presbyphagia using standardized assessment tools would facilitate new avenues to reduce the risk of dysphagia in older adults.

The Prevalence of Oropharyngeal Dysphagia in Adults: A Systematic Review and Meta-analysis

To determine the global prevalence of oropharyngeal dysphagia (OD) in adults. Six electronic databases (Embase, LILACS, LIVIVO, PubMed/Medline, Scopus, and Web of Science) were searched, in addition to gray literature (ASHA, Google Scholar, ProQuest Dissertation, and Theses). A random-effects model for meta-analysis of proportions was conducted, and heterogeneity was evaluated according to the moderator variable through subgroup analysis and meta-regression. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist and the certainty of the evidence was assessed using the GRADE tool. Thirty papers were included for qualitative and quantitative synthesis. The combined prevalence estimate was 60% [CI 95% = 50%-70%; I2 = 95%], accounting for different baseline conditions. However, the wide variation that exists between the different baseline conditions (underlying disease or risk factor) tended to overestimate this prevalence when considering the general population. Only one study evaluated healthy individuals, which showed a prevalence of 31% [CI95% = 27%-36%]. The risk of bias was considered low for all studies. None of the variables were considered predictors for the observed variance between the effect sizes of the included studies. For the prevalence of OD, the GRADE rating was considered very low. Despite the high prevalence observed, with over half of the individuals affected, the evidence regarding this outcome remains uncertain due to an overestimation of the generated estimates caused by the baseline condition of the sample.

Study on predictive models for swallowing risk in patients with AECOPD

BACKGROUND

Dysphagia is considered a complication in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). However, AECOPD may have risk factors for dysphagia.

METHODS

Through a cross-sectional study, which included 100 patients with AECOPD. General information, Pulmonary function, COPD assessment test (CAT) and modified Medical Research Council (mMRC) were collected by questionnaire. The questionnaires were administered by uniform-trained investigators using standard and neutral language, and swallowing risk was assessed by using a water swallow test (WST) on the day of patient admission.

RESULTS

Among the 100 included patients, 50(50%) were at risk of swallowing. Multivariate analysis using logistic regression analysis showed that age ≥ 74 years old, mMRC ≥ level 2, hospitalization days ≥ 7 days and the use of BIPAP assisted ventilation were important influencing factors for swallowing risk in patients with AECOPD.

CONCLUSION

Patients with AECOPD are at risk for dysphagia, assessing age, mMRC, hospitalization days and the use of BIPAP assisted ventilation can be used to screen for swallowing risk, thus contributing to the implementation of early prevention measures.

The Clinical Frailty Scale as a Risk Assessment Tool for Dysphagia in Older Inpatients: A Cross-Sectional Study

BACKGROUND

Dysphagia is a common problem with potentially serious consequences including malnutrition, dehydration, pneumonia, and death. However, there are challenges in screening for dysphagia in older adults. We assessed the feasibility of using the Clinical Frailty Scale (CFS) as a risk assessment tool for dysphagia.

METHODS

This cross-sectional study was conducted at a tertiary teaching hospital from November 2021 to May 2022 and included 131 older patients (age ≥65 years) admitted to acute wards. We used the Eating Assessment Tool-10 (EAT-10), which is a simple measure for identifying individuals at risk of dysphagia, to assess the relationship between EAT-10 score and frailty status as measured using the CFS.

RESULTS

The mean age of the participants was 74.3±6.7 years, and 44.3% were male. Twenty-nine (22.1%) participants had an EAT-10 score ≥3. The CFS was significantly associated with an EAT-10 score ≥3 after adjusting for age and sex (odds ratio=1.48; 95% confidence interval [CI], 1.09-2.02). The CFS was able to classify the presence of an EAT-10 score ≥3 (area under the receiver operating characteristic [ROC] curve=0.650; 95% CI, 0. 544-0.756). The cutoff point for predicting an EAT-10 score ≥3 was a CFS of 5 according to the highest Youden index, with a sensitivity of 82.8% and a specificity of 46.1%. The positive and negative predictive values were 30.4% and 90.4%, respectively.

CONCLUSION

The CFS can be used as a tool to screen for the risk of swallowing difficulty in older inpatients to determine clinical management encompassing drug administration routes, nutritional support, prevention of dehydration, and further evaluation of dysphagia.

Dysphagia screening and pneumonia after subarachnoid hemorrhage: Findings from the Chinese stroke center alliance

BACKGROUND AND PURPOSE

Dysphagia is common and is associated with aspiration pneumonia. However, little is known about the prevalence of and factors influencing dysphagia screening (DS) and pneumonia after subarachnoid hemorrhage (SAH).

METHODS

We used data on SAH patients admitted to 1476 hospitals from the China Stroke Center Alliance (CSCA) from August 2015 to July 2019 to analyze the rates of DS and pneumonia. We then conducted univariate and multivariable analyses to examine the relationship between DS and pneumonia.

RESULTS

Among 4877 SAH patients who were eligible for DS and had complete data on pneumonia status, 3527 (72.3%) underwent DS, and 1006 (20.6%) developed pneumonia. Compared with patients without pneumonia, patients with pneumonia were older (mean: 63.4 vs. 57.8 years of age), had lower Glasgow Coma Scale (GCS) scores at admission (mean: 13.5 vs. 14.3), were more likely to have dysphagia (15.2% vs. 3.3%), and were more likely to have undergone aneurysm isolation (19.1% vs. 10.0%). In multivariable analyses, factors independently associated with a higher risk of pneumonia were dysphagia [odds ratio (OR), 3.77; 95% confidence interval (CI), 2.85-4.98], age (OR, 1.50 per 10-year increase; 95% CI, 1.40-1.60), male sex (OR, 1.23; 95% CI, 1.02-1.49), arrival at the hospital by emergency medical services (OR, 1.36; 95% CI, 1.16-1.58), nimodipine treatment (OR, 1.42; 95% CI, 1.11-1.81), endovascular embolization of aneurysms (OR, 1.23; 95% CI, 1.03-1.47), cerebral ventricular shunt placement (OR, 2.24; 95% CI, 1.41-3.54), and treatment at a higher grade hospital (OR, 1.44; 95% CI, 1.21-1.71).

CONCLUSION

More than a quarter of patients with SAH did not have documented DS, while one-fifth developed pneumonia. DS performance was associated with a lower risk of pneumonia. Randomized controlled trials may be needed to determine the effectiveness of DS.

Prevalence and Methods for Assessment of Oropharyngeal Dysphagia in Older Adults: A Systematic Review and Meta-Analysis

BACKGROUND

This systematic review and meta-analysis aimed to estimate the pooled prevalence of dysphagia in older adults, subgrouping by recruitment settings and varying dysphagia assessment methods.

METHODS

Five major databases were systematically searched through January 2022. A random-effects model for meta-analysis was conducted to obtain the pooled prevalence.

RESULTS

Prevalence of dysphagia in the community-dwelling elderly screened by water swallow test was 12.14% (95% CI: 6.48% to 19.25%, I2 = 0%), which was significantly lower than the combined prevalence of 30.52% (95% CI: 21.75% to 40.07%, I2 = 68%) assessed by Standardized Swallowing Assessment (SSA) and volume-viscosity swallow test (V-VST). The dysphagia prevalence among elderly nursing home residents evaluated by SSA was 58.69% (95% CI: 47.71% to 69.25%, I2 = 0%) and by the Gugging Swallowing Screen test (GUSS) test was 53.60% (95% CI: 41.20% to 65.79%, I2 = 0%). The prevalence of dysphagia in hospitalized older adults screened by the 10-item Eating Assessment Tool was 24.10% (95% CI: 16.64% to 32.44%, I2 = 0%), which was significantly lower than those assessed by V-VST or GUSS tests of 47.18% (95% CI: 38.30% to 56.14%, I2 = 0%).

CONCLUSIONS

Dysphagia is prevalent in the elderly, affecting approximately one in three community-dwelling elderly, almost half of the geriatric patients, and even more than half of elderly nursing home residents. The use of non-validated screening tools to report dysphagia underestimates its actual prevalence.

Association between Dysphagia and Frailty in Older Adults: A Systematic Review and Meta-Analysis

BACKGROUND

Increasing bodies of epidemiological evidence indicate potential associations between dysphagia and the risk of frailty in older adults. We hypothesized that older adults with symptoms of dysphagia might have a higher prevalence of frailty or prefrailty than those without dysphagia.

METHODS

We systematically searched the PubMed, Embase, and Cochrane Library databases for relevant studies published through 20 April 2022. Cross-sectional and longitudinal studies that examined the associations between dysphagia and the existence of frailty or prefrailty in community-dwelling, facility-dwelling, or hospitalized adults aged 50 years or older were synthesized. The Newcastle-Ottawa Scale was used to evaluate study quality.

RESULTS

The meta-analysis comprised 12 cohorts, including 5,503,543 non-frailty participants and 735,303 cases of frailty or prefrailty. Random-effect meta-analysis demonstrated a significant association between dysphagia and the risk of frailty and prefrailty (OR, 3.24; 95% CI, 2.51-4.20). In addition, we observed consistent results across the subgroups and heterogeneity assessments.

CONCLUSIONS

We propose including dysphagia assessment as a critical factor in the cumulative deficit model for identifying frailty in older adults. Understanding dysphagia and the potential role of nutritional supplements in older adults may lead to improved strategies for preventing, delaying, or mitigating frailty.

Usefulness of the Modified Videofluoroscopic Dysphagia Scale in Determining the Allowance of Oral Feeding in Patients with Dysphagia Due to Deconditioning or Frailty

Introduction: In patients with dysphagia due to deconditioning or frailty, as with other disorders that cause swallowing disorders, the videofluoroscopic swallowing study (VFSS) is the gold standard for dysphagia evaluation. However, the interpretation of VFSS results is somewhat complicated and requires considerable experience in the field. Therefore, in this study we evaluated the usefulness of the modified videofluoroscopic dysphagia scale (mVDS) in determining whether to allow oral feeding in patients with dysphagia due to deconditioning or frailty. Methods: Data from the VFSS of 50 patients with dysphagia due to deconditioning or frailty were retrospectively collected. We evaluated the association between mVDS and the selected feeding method based on VFSS findings, and between mVDS and the presence of aspiration pneumonia. Results: Multivariate logistic analysis showed that the mVDS total score had a significant association with oral feeding methods based on VFSS findings in patients with dysphagia due to deconditioning or frailty (p < 0.05). In the receiver operating characteristic (ROC) curve analysis, the area under the ROC curve for the selected feeding method was 0.862 (95% confidence interval, 0.747−0.978; p < 0.0001). Conclusions: mVDS seems a valid scale for determining the allowance of oral feeding, and it can be a useful tool in the clinical setting and in studies that aim to interpret VFSS findings in patients with dysphagia due to deconditioning or frailty. However, studies involving a more general population of patients with dysphagia due to deconditioning or frailty are needed.

Association between Oral Frailty and Physical Frailty among Rural Middle-Old Community-Dwelling People with Cognitive Decline in Taiwan: A Cross-Sectional Study

This cross-sectional study was conducted to clarify the association between oral frailty (OF) and physical frailty (PF). In total, 308 Taiwanese middle-old (75−84 years) community-dwelling people with cognitive decline were recruited from random rural community health care centers. Eight items were considered for the evaluation of their OF status. The Study of Osteoporotic Fracture index was used for frailty assessment, which revealed that 22% of the participants had PF. In an adjusted model, PF was significantly associated with the OF subdomains of difficult to eat hard food (p = 0.009), choking (p = 0.008), denture use (p = 0.008), and inability to chew hard food (p = 0.001); and high risk of OF (OR = 3.03; p = 0.002). After eight steps with elimination of the least significant independent variable, age (p= 0.008), self-reported health status of fair (p = 0.000) and poor (p = 0.000), mild cognitive impairment (p < 0.001) and denture use (p = 0.011) were found to be the indispensable predictors for PF. The logistic regression model with 5 indispensable variables had a predictive value of 78.2%. Longitudinal analyses are needed to examine whether OF is a risk factor for PF onset.

Prevalence of Oropharyngeal Dysphagia and Risk of Pneumonia, Malnutrition, and Mortality in Adults Aged 60 Years and Older: A Meta-Analysis

INTRODUCTION

Oropharyngeal dysphagia (OD) is a serious health condition associated with poor survival and quality of life in adults aged 60 years and older. Comprehensive assessment and management of OD could lead to better and improved health outcomes for older adults. Therefore, we performed the first meta-analysis to determine the pooled prevalence of OD and risk of pneumonia, malnutrition, and mortality.

METHODS

Databases including Ovid-MEDLINE, Web of Science, Embase, PubMed, Cochrane, and CINAHL were searched up to January 2021. Data analysis was conducted using logistic-normal for prevalence rate and DerSimonian-Lard random-effects models for outcomes and associated factors of OD, providing odds ratio (OR) and corresponding 95% confidence interval (CI).

RESULTS

The pooled prevalence of OD in 39 studies with 31,488 participants was 46% associated with higher pooled OR for risk of pneumonia 2.07 (95% CI, 1.58-2.72), malnutrition 2.21 (95% CI, 1.43-3.41), and mortality 2.73 (95% CI, 1.62-4.60). Geriatric syndromes including fecal incontinence 6.84 (4.955-9.44), immobility syndrome 6.06 (5.28-6.96), pressure ulcers 4.02 (2.46-6.56), sarcopenia 3.10 (1.89-5.09), urinary incontinence 2.75 (1.81-4.19), frailty 2.66 (1.16-6.13), delirium 2.23 (1.73-2.87), and falls 1.47 (1.19-1.81) and comorbidities including dementia 3.69 (2.36-5.78) and stroke 1.92 (1.47-2.52) were associated with OD.

CONCLUSION

Early identification and management of OD should consider geriatric syndromes and neurogenic comorbidities to prevent malnutrition and pneumonia and reduce mortality in adults aged 60 years and older.

Videofluoroscopic Swallowing Study Findings Associated With Subsequent Pneumonia in Patients With Dysphagia Due to Frailty

Dysphagia in frailty or deconditioning without specific diagnosis that may cause dysphagia such as stroke, traumatic brain injury, or laryngeal pathology, has been reported in previous studies; however, little is known about which findings of the videofluoroscopic swallowing study (VFSS) are associated with subsequent pneumonia and how many patients actually develop subsequent pneumonia in this population. In this study, we followed 190 patients with dysphagia due to frailty or deconditioning without specific diagnosis that may cause dysphagia for 3 months after VFSS and analyzed VFSS findings for the risk of developing pneumonia. During the study period, the incidence of subsequent pneumonia was 24.74%; regarding the VFSS findings, (1) airway penetration (PAS 3) and aspiration (PAS 7 and 8) were associated with increased risk of developing pneumonia, and (2) the functional dysphagia scale (FDS) scores of the patients who developed subsequent pneumonia were higher than those of the patients who did not develop subsequent pneumonia. Our study findings might assist clinicians in making clinical decisions based on the VFSS findings in this population.

Synergistic Effects of Aldehyde Dehydrogenase 2 Polymorphisms and Alcohol Consumption on Cognitive Impairment after Ischemic Stroke in Han Chinese

Aldehyde dehydrogenase 2 (ALDH2) polymorphisms are related to both stroke risk and alcohol consumption. However, the influence of ALDH2 polymorphisms and alcohol consumption on cognitive impairment after ischemic stroke remains unknown, as do the possible mechanisms. We enrolled 180 Han Chinese ischemic stroke patients from four community health centers in Bengbu, China. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), and two different MoCA cutoff scores were used to define cognitive impairment in ischemic stroke patients. The ALDH2 genotypes were determined using polymerase chain reaction and direct sequencing. To assess the associations of ALDH2 polymorphisms and alcohol consumption with cognitive impairment after ischemic stroke, we performed binary logistic regression analysis with odds ratios. We revealed that individuals with the ALDH2 wild-type genotype were more likely to have high MoCA scores than those with the mutant and heterozygous types (p = 0.034). In addition, using two MoCA cutoff scores, the percentage of moderate to excessive alcohol consumption in the cognitive impairment group was higher than that in the nonimpairment group (p = 0.001). The levels of 4-hydroxy-2-nonenal (p = 0.001) and swallowing function (p = 0.001) were also higher in the cognitive impairment group than in the nonimpairment group. Moreover, after adjusting for other potential risk factors, ALDH2 polymorphisms and alcohol consumption had a significant synergistic effect on cognitive impairment (p = 0.022). Specifically, the ALDH2∗2 mutant allele and higher alcohol consumption were associated with cognitive impairment and swallowing ability after ischemic stroke. Targeting ALDH2 may be a useful biomarker for cognitive rehabilitation following ischemic stroke.
