Dysphagia screening in residential care settings: A scoping review

Development and Validation of a Prediction Model for Dysphagia in Community-Dwelling Older Adults

Objectives. Dysphagia is a geriatric syndrome, which may lead to complications such as dehydration, malnutrition, aspiration, pneumonia, and a significant reduction in quality of life. The purpose of this study was to construct and validate a prediction model for dysphagia in community-dwelling older adults and provide an assessment tool for the prevention and control of dysphagia. Design. Cross-sectional study. Setting. The community-dwelling Chinese older adults. Participants. 3655 participants aged 65 years and older were involved, who were randomly divided into the training set and the validation set. Methods. Data were collected and analyzed from June 2022 to September 2022. Univariate and multivariate logistic regression analysis were used to identify independent risk factors for dysphagia. We applied R software to develop a nomogram model to predict dysphagia in community-dwelling older adults. The predictive value of the model was assessed by the area under the ROC curve (AUC), the calibration curve was used to evaluate the reliability of the nomogram model for predicting dysphagia in community-dwelling older adults. The model's clinical utility was further evaluated using a Decision Curve Analysis (DCA). Results. The incidence of dysphagia was 11.8% (320/3655). Maximum tongue pressure, number of molars, pneumonia, ADL, sarcopenia, age, neurological diseases, and rheumatic immune diseases were selected as risk predictors for dysphagia. The prediction model demonstrated fair discriminative ability with the AUC was 0.709 (95%CI: 0.679-0.739) in the training set and 0.693 (95%Cl: 0.640-0.747) in the validation set, the calibration is adequate, and the Hosmer and Lemeshow test showed p values of 0.163 and 0.415, respectively. The DCA curve of our model shows a positive clinical net benefit. Conclusions. The prediction model established in this study was of a certain predictive value for the risk of dysphagia in community-dwelling older adults. By estimating the likelihood of future outcomes or the onset of certain diseases, it can assist medical personnel in formulating preventive strategies, lessening the workload of nurses, and also diminishing the financial burden on patients, thereby enhancing their overall quality of life.

Association of dysphagia and loneliness and their interaction with sleep quality among older adults in nursing homes: A cross-sectional study

OBJECTIVE

Poor sleep quality is a risk factor for many adverse health outcomes and has become a widespread and serious public health problem, especially among older adults. This study aimed to explore the association between dysphagia, loneliness, and their interaction with sleep quality among older Chinese adults living in nursing homes.

METHODS

This cross-sectional study used multistage cluster random sampling to select 56 nursing homes in Hunan Province, China. Data on sociodemographic characteristics, health-related status, lifestyle, and behavioral and social psychological factors were collected. The Pittsburgh Sleep Quality Index was used to evaluate sleep quality. The 30 mL Water Swallowing Test and Eating Assessment Tool-10 items were used to screen for dysphagia, and the 14th item of the Center for Epidemiologic Studies Depression Scale was used to measure loneliness. Binary logistic regression models were used to analyze the relationship between poor sleep quality, dysphagia, and loneliness. The interaction between these variables was evaluated using multiplicative and additive interaction models.

RESULTS

This study included 3,356 older adults aged 60 and above. The mean Pittsburgh Sleep Quality Index score was 6.31 ± 3.11, and the incidence of poor sleep quality was 30.8%. A total of 642 (19.1%) older adults had dysphagia, and 1,358 (40.5%) experienced loneliness. After adjusting for all covariates, dysphagia and loneliness were associated with an increased risk of poor sleep quality. The interaction analysis demonstrated that the risk of poor sleep quality among older adults with dysphagia and loneliness was 3.476 times higher than that in those without dysphagia and loneliness. Dysphagia and loneliness had an additive interaction effect on poor sleep quality in older adults living in nursing homes.

CONCLUSIONS

Poor sleep quality can be effectively prevented by focusing on older adults in nursing homes experiencing dysphagia, loneliness, or both and implementing targeted health interventions.

Dysphagia in schizophrenia: pathological mechanisms and treatment recommendations

Schizophrenia is a chronic, severe, and disabling mental disorder that significantly impacts individuals' lives. Long-term treatment with antipsychotic drugs, coupled with the complications of the disease itself, increases the risk of dysphagia in patients. These disorders further heighten the likelihood of choking and asphyxia death among this population. This project aims to comprehensively review the pathological mechanisms behind dysphagia in schizophrenia, alongside proposing early screening and evaluation methods. It also suggests treatment recommendations to mitigate the risks and complications associated with dysphagia in these patients.

Tackling unmanaged oropharyngeal dysphagia in primary care: a behavioural science realist review of interventions

INTRODUCTION

Oropharyngeal dysphagia (OD) is difficulty manipulating a food bolus from the mouth to the throat. Up to 70% of older adults develop OD; however, it is unmanaged in primary care, leading to avoidable hospitalisation.

OBJECTIVE

This behavioural science realist review aimed to develop programme theories to describe how interventions facilitate primary care healthcare professionals (HCPs) to proactively manage OD.

METHODS

We developed initial programme theories (IPTs) inductively using the expertise of stakeholders and deductively using the theoretical domains framework (TDF). Databases were searched to identify evidence regarding contexts, behavioural mechanisms and outcomes related to proactive management of OD and comparative behaviours which offer transferrable learning. IPTs were tested with the evidence to confirm, refine or refute, to produce final programme theories.

RESULTS

36 sources of evidence were included. Five final programme theories were generated explaining how primary care HCPs can be facilitated to proactively manage OD: (1) OD education and training, (2) checklists with OD signs and symptoms, (3) incorporating OD identification into existing workflow, (4) making HCPs aware that older adults and carers expect them to manage OD and (5) raising awareness of the adverse outcomes of OD.

CONCLUSION

The five programme theories provide the behavioural mechanisms by which an intervention may facilitate primary care HCPs to proactively manage OD. Through the programme theories' linkage to the TDF, behaviour change techniques (BCTs) mapped to the relevant TDF domain can be selected for an intervention. Operationalisation of selected BCTs into a coherent intervention package should be undertaken using codesign methodology.

Aspiration pneumonia in nursing literature-a mapping review

Introduction

Aspiration pneumonia (AP) is an infection of the lungs caused by inhalation of material. The reported incidences vary across literature and clinical populations and is associated with high morbidity and mortality. Management of AP is best carried out by a multidisciplinary team.

Methods

This aim of this review was to collate and describe the available evidence on AP to develop a greater understanding of the concept of AP as it is represented in the nursing literature. As a collaborative team, we undertook the six stages of a systematic mapping review. We searched for the term aspiration pneumonia in 200 peer reviewed nursing journals across 10 databases, over a ten-year period (2013-2023).

Results

In this review, 293 papers were coded. Dysphagia, oral health and tube feeding emerged as the most frequent risk factors for AP, and the most reported factors for preventing this condition. Mortality was the most commonly described consequence of AP, followed by hospitalisations and morbidity. Multiple management approaches were reported including dysphagia assessment, risk evaluation, oral care and texture modification of food and fluids. The role of nurses and interprofessional collaborations were described.

Discussion

Despite limited evidence related to the topic of AP in the nursing literature, the complexity of the causes, prevention, management and consequences of AP emerged. Certain factors, such as dysphagia, oral health, and tube feeding, were described under prevention, cause and management of AP. The importance of multidisciplinary approach in the management and prevention of AP was presented.

The development, feasibility and credibility of intra-abdominal pressure measurement techniques: A scoping review

AIM

To provide a comprehensive overview on emerging direct and alternative methods for intra-abdominal pressure (IAP) measurement techniques.

METHODS

This was a scoping review study following Arksey and Malley's framework. The PubMed, EMBASE, Web of Science, EBSCO, Scopus and ProQuest databases were searched, and we only considered studies published from 2000 as we have extended the data from two previous reviews. Original studies that reported on the development, feasibility and credibility of IAP measurement techniques were included.

RESULTS

Forty-two of 9954 screened articles were included. IAP measurement techniques include three major categories: direct, indirect and less invasive measurement techniques. Agreement analyses were performed in most studies, and some explored the safety, time expenditure and reproducibility of IAP measurement techniques.

CONCLUSIONS

Clinical data assessing the validation of new IAP measurement techniques or the reliability of established measurement techniques remain lacking. Considering the cost and invasiveness, direct measurement is not recommended as a routine method for IAP measurement and should be preserved for critically ill patients where standard techniques are contraindicated or could be inaccurate. The measurement accuracy, reliability and sensitivity of the transrectal and transfemoral vein methods remain insufficient and cannot be recommended as surrogate IAP measures. Transvesical measurement is the most widely used method, which is the potentially most easy applicable technique and can be used as a reliable method for continuous and intermittent IAP measurement. Wireless transvaginal method facilitates the quantitative IAP measurement during exercise and activity, which laying the foundations for monitoring IAP outside of the clinic environment, but the accuracy of this technique in measuring absolute IAP cannot be determined at present. Less invasive technology will become a new trend to measure IAP and has substantial potential to replace traditional IAP measurement technologies, but further validation and standardization are still needed. Medical professionals should choose appropriate measurement tools based on the advantages and disadvantages of each IAP technique in combination with assessing specific clinical situations.

The prevalence of dysphagia at risk among older adults in nursing homes: a meta-analysis

To estimate the prevalence of dysphagia at risk among older adults in nursing homes. Electronic databases of PubMed, Web of Science, CINAHL and Embase for English language, WanFang, VIP and CNKI for Chinese language were systematically searched to identify relevant observational studies published not later than July 4, 2021. Studies conducted in nursing homes and reported dysphagia screening or assessment methods were included. In total, 43 studies involving 56 746 participants were included in this meta-analysis. The overall pooled crude prevalence of dysphagia at risk was 35.9% (95% CI: 29.0-43.4%), with high heterogeneity (I2  = 99.5%). There was a statistically significant difference in prevalence estimates with respect to study locations, dysphagia assessment staff and representativeness of samples. The prevalence of dysphagia among older adults in nursing homes is relatively high. Routine screening strategy for dysphagia is necessary for older adults in nursing homes.

Clinical practice patterns of speech-language pathologists for screening and identifying dysphagia

PURPOSE

To identify how speech-language pathologists (SLPs) in the United States are screening for and identifying dysphagia. To do this, we examined the approaches most often used to screen for dysphagia and the influence of contextual factors such as setting, continuing education and means of staying up to date with the most current literature on screening approaches.

METHOD

A web-based survey composed of 32 questions was developed and field tested for content, relevance and workflow. The survey was distributed online, via social media, online SLP forums and through the American Speech-Language-Hearing Association's Special Interest Group 13 (swallowing disorders). One hundred and thirty-seven clinicians from the United States completed the survey and were included for analysis using descriptive statistics and linear regression modelling to assess associations of continuing education and years practicing with screening protocols and consumption of evidence.

RESULTS

Respondents worked in a variety of settings, including acute care, skilled nursing facilities, and inpatient rehabilitation. Most respondents worked with adult populations (88%). The most common screening protocols reported were a volume-dependent water swallow test (74%), subjective patient report (66%), and trials of solids/liquids (49%). Twenty-four percent (24%) reported using a questionnaire, the Eating Assessment Tool (80%) being most common. How clinicians consume their evidence was significantly associated with the types of screening approaches used. Continuing education hours were significantly associated with dysphagia screening protocol choice (p < 0.001) and how clinicians stayed up to date with evidence (p < 0.001).

CONCLUSIONS

Results from this study provide an in-depth look at the choices clinicians are making in the field regarding how to effectively screen patients for the presence of dysphagia. Contextual factors such as evidence base consumption patterns should serve researchers to continue seeking alternative ways to share evidence with clinicians, accessibly. Associations between continuing education and protocol choice show the need for continued evidence-based and high-quality continuing education opportunities.

WHAT THIS PAPER ADDS

This study provides an in-depth look at the choices clinicians are making in the field regarding effective dysphagia screening practices. Clinician screening choices are examined with contextual factors such as evidence base consumption patterns and continuing education. This paper increases knowledge of the most used dysphagia screening practices and context for clinicians and researchers to improve use, evidence and dissemination of best practices.

Cross-sectional study on dysphagia evaluation in community-dwelling older adults using the Eating Assessment Tool (EAT) -10, EAT-2, and Water Swallow Test

BACKGROUND

Dysphagia is a health concern that causes severe complications and affects the life quality of the older population. This study aimed to determine the diagnostic performance of the Eating Assessment Tool (EAT)-2 compared with the EAT-10 and the Water Swallow Test (WST) in screening for dysphagia.

METHODS

A cross-sectional study was conducted among 5,090 community-dwelling older adults. Dysphagia was evaluated using both a subjective measure, the 10-item EAT (EAT-10) and an objective measure, the WST. The kappa index in pairs were analyzed. The validity and reliability of EAT-2 were also assessed.

RESULTS

The sensitivity and specificity of the EAT-2 were 96.3 % and 94.8 %, respectively. The kappa index between the EAT-2 and EAT-10 was 0.64, whereas it was 0.11 between the EAT-10 and WST.

CONCLUSIONS

The EAT-2 was a simpler screening tool for dysphagia. Combining the subjective questionnaire (EAT-10 or EAT-2) and the objective test (WST) is recommended.

Association between health literacy and dysphagia in the community-dwelling older population: a cross-sectional study

BACKGROUND

Dysphagia, or swallowing disorders, has become a growing concern due to the aging population, and health literacy plays a crucial role in active aging. However, the relationship between them remains unclear.

AIMS

To investigate the association between health literacy and dysphagia among community-dwelling older adults in China.

METHODS

A survey was conducted on 4462 older adults aged 65 and above in a community in Yiwu City, China, from May 2021 to January 2022. Swallowing problems were assessed using a 30 ml water swallowing test (WST) and the Eating Assessment Tool-10 questionnaire (EAT-10). The participants' health literacy was evaluated using the Chinese Health Literacy Scale (CHLS). Logistic regression and t tests were employed to measure the association between them.

RESULTS

The prevalence of dysphagia was 5.70% and 7.85% as determined by EAT-10 and 30 ml-WST, respectively. The health literacy level of community-dwelling older adults was 24.4 ± 4.93 (9-45). Participants with dysphagia exhibited lower levels of health literacy (p < 0.05). The logistic regression model demonstrated an inverse association between health literacy and dysphagia (OR = 0.94, 95%CI = 0.91-0.96 for EAT-10, and OR = 0.93, 95%CI = 0.92-0.95 for WST). Moreover, this association remained significant even after adjusting for covariates.

DISCUSSION

Older adults with dysphagia have lower levels of health literacy, particularly in terms of their ability to seek medical advice, acquire and evaluate medical information, and access social support resources.

CONCLUSIONS

Health literacy is associated with dysphagia among community-dwelling older adults. Effective interventions should be implemented to provide support in terms of both medical services and social support for this population.

Validation of a Geriatric Bedside Swallowing Screen (GEBS): Protocol of a Prospective Cohort Study

BACKGROUND

Demographic changes will raise the need for specialized care of older patients. Oropharyngeal dysphagia has recently been declared a geriatric syndrome reflecting its multifactorial background. Alongside multimorbidity, sarcopenia, frailty, and disability, swallowing disorders increase with advancing age, with prevalence rates reported to be as high as 44% in acute geriatric hospital settings and 80% in long-term care facilities. Hence, systematic screening of older patients to diagnose dysphagia and initiate treatment is of paramount importance to prevent bolus death, aspiration pneumonia, and malnutrition and improve quality of life. Several screening tools have been evaluated in emergency and stroke units. However, no published dysphagia screening tool has been validated in the hospitalized, older adult population using a gold standard in dysphagia diagnostics as a reference test. The validation of the proposed test is a first step.

OBJECTIVE

The Geriatric Bedside Swallowing Screen (GEBS) study aims to validate a new screening tool developed specifically for older inpatients against an instrumental swallowing evaluation, the flexible endoscopic evaluation of swallowing (FEES), which is considered a gold standard. Primary outcomes to be evaluated are sensitivity and specificity for the GEBS in the detection of dysphagia in a mixed older adult population. The presence of dysphagia will be defined by an instrumental swallowing evaluation (FEES), analyzed by the standardized penetration-aspiration scale.

METHODS

To validate the GEBS, a prospective cohort study will be carried out. Two institutions, an acute geriatric department and a long-term care facility, will aim to recruit a total of 100 patients aged ≥75 years. After giving their informed consent, patients will undergo the full screening protocol described in the GEBS as well as an evaluation of swallowing function using the FEES. Investigators will be blinded to the results of the respective other testing. The analysis of pseudonymized data sets will be done by a third investigator. Outcomes to be considered are sensitivity, specificity, diagnostic odds ratio, positive and negative likelihood quotient, and the reliability of the proposed dysphagia screening tool using the κ coefficient.

RESULTS

Recruitment started in October 2022 and will end in April 2024. Data publication is planned for early 2025.

CONCLUSIONS

If proven to be a valid screening tool for the early detection of dysphagia, further studies including different older adult populations as well as studies to determine the impact of systematic dysphagia screening on parameters, such as rates of aspiration pneumonia or nutritional status, should be planned. Effective screening of dysphagia will lead to earlier detection of patients with impaired swallowing. Those who fail the screening will be referred to speech language pathology for further diagnosis, thus optimizing care while streamlining personnel resources.

Gustatory stimulus interventions for older adults with dysphagia: a scoping review

BACKGROUND

Gustatory stimulus interventions have been shown to improve swallowing function in older adults with dysphagia. However, the optimal intervention strategies as well as their effects and safety remain unclear.

AIMS

To explore current evidence regarding gustatory stimulus interventions for dysphagia in older adults.

METHODS

Nine electronic databases (PubMed, Web of Science, Embase, CINAHL, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database, China Science and Technology Journal Database, and Sinomed) were searched from their inception to August 2022.

RESULTS

This review identified 263 articles, and 15 met the inclusion criteria. The types of gustatory stimulus interventions included spicy (n = 10), sour (n = 3), and mixed (sour-sweet) stimuli (n = 2), with most studies focusing on spicy stimuli. The most frequently reported spicy stimulus was capsaicin. Further, the most commonly reported intervention frequency was thrice a day before meals for 1-4 weeks. The stimuli concentrations and dosages could not be standardized due to the among-study heterogeneity. These studies reported 16 assessment tools and 42 outcomes, which mainly included videofluoroscopy and swallowing response time respectively. More than half of the included studies reported no adverse effects of gustatory stimulus interventions.

CONCLUSION AND DISCUSSIONS

Gustatory stimulus interventions improved swallowing function in older adults with dysphagia. However, assessment tools and outcomes for dysphagia should be standardized in the future, and explore personalized interventions based on different diseases and their stages, to determine the most cost-effective interventions, and to prevent its complications.

Instrumental swallowing assessment in adults in residential aged care homes: Practice patterns and opportunities

OBJECTIVE

To describe practice patterns in the use of instrumental swallowing assessment (ISA) for older adults in residential aged care homes (RACHs).

METHODS

A retrospective audit of medical records of residents living in RACHs in Melbourne, Australia to extract data on speech-language pathologist (SLP) involvement, indications for ISA and ISA practice patterns.

RESULTS

Medical files of 323 residents across four Melbourne facilities were reviewed. 36% (n = 115) of residents were referred to SLP for swallowing assessment. Referral to SLP was related to length of stay (U = 7393.00, p < 0.001), dementia status (χ2 [1] = 7.06, p = 0.008), texture modification (χ2 [1] = 93.34, p < 0.001) and an existing dysphagia diagnosis (χ2 [1] = 112.89, p < 0.001). There were no referrals for ISA and no instances of ISA being used. Among 115 residents who were referred to SLP for swallowing assessment, there were 33 instances where ISA might be clinically relevant according to ISA indicators.

CONCLUSIONS

Instrumental swallowing assessment is not being used for the management of swallowing in RACHs in Australia despite a clinical need for ISA and a potential role for ISA to improve swallowing care quality. Lack of timely ISA may fail to meet the complex health-care needs of older adults living with dysphagia in RACHs, increasing their vulnerability to complications of dysphagia and its management.

A scoping review of the evidence for the use of screening tools in people with intellectual disabilities with dysphagia

BACKGROUND

Dysphagia can have serious health implications including choking and respiratory infection leading to poorer quality of life. People with intellectual disabilities are at higher risk of dysphagia related health complications and early death. Robust dysphagia screening tools are vital for this population.

METHOD

A scoping review and appraisal of the evidence for dysphagia and feeding screening tools for use with people with intellectual disabilities was undertaken.

RESULTS

Seven studies (using six screening tools) met the review inclusion criteria. Mostly studies were limited by no defined dysphagia criteria, no verification of tools with a gold reference standard (e.g., videofluoroscopic examination) and lack of participant diversity (small samples, narrow age range, severity of intellectual disability or limited settings).

CONCLUSIONS

There is urgent need for development and rigorous appraisal of existing dysphagia screening tools to meet the needs of a wider range of people with intellectual disabilities (particularly mild-to-moderate severity) and in wider settings.

Diagnostic Accuracy of the Eating Assessment Tool-10 (EAT-10) in Screening Dysphagia: A Systematic Review and Meta-Analysis

The Eating Assessment Tool-10 (EAT-10) is used worldwide to screen people quickly and easily at high risk for swallowing disorders. However, the best EAT-10 cutoff value is still controversial. In this systematic review and meta-analysis, we estimated and compared the diagnostic accuracy of EAT-10 cutoff values of 2 and 3 for screening dysphagia. We searched the PubMed, Web of Science, EMBASE, Cochrane Library, CNKI, WANFANG, and VIP databases from May 2008 to March 2022. The meta-analysis included 7 studies involving 1064 subjects from 7 different countries. Two studies were classified as high quality and five studies as medium quality. With an EAT-10 cutoff value of 2, using flexible endoscopic evaluation of swallowing or video fluoroscopic swallowing study as the gold standard, the pooled sensitivity, specificity, positive and negative likelihood ratios, and diagnostic odds ratio were 0.89 (95% confidence interval [CI] 0.82-0.93), 0.59 (95% CI 0.39-0.77), 2.17 (95% CI 1.38-3.42), 0.19 (95% CI 0.13-0.29), and 11.49 (95% CI 5.86-22.53), respectively. When a cutoff of 3 was used, these values were 0.85 (95% CI 0.68-0.94), 0.82 (95% CI 0.65-0.92), 4.84 (95% CI 1.72-13.50), 0.18 (95% CI 0.07-0.46), and 26.24 (95% CI 5.06-135.95), respectively. Using EAT-10 cutoff values of 2 and 3, the areas under the curve were 0.873 (95% CI 0.82-0.93) and 0.903 (95% CI 0.88-0.93), respectively, showing good diagnostic performance. EAT-10 can be used as a preliminary screening tool for dysphagia. However, a cutoff of 3 is recommended for EAT-10 due to better diagnostic accuracy.

Physiological Mechanisms and Associated Pathophysiology of Dysphagia in Older Adults

Dysphagia can be a common secondary sequela of neurological and neurodegenerative disorders in older adults. Early screening, identification, and management of dysphagia is essential to avoid serious complications, including malnutrition, dehydration, aspiration pneumonia; and promote quality of life. Although individuals of all ages may experience swallowing difficulties, dysphagia and its complications are more common in older adults. This literature review aims to provide an overview of the physiological mechanisms of normal swallowing in healthy individuals and age-related changes to swallowing function, the pathophysiology of dysphagia associated with three common neurological disorders affecting older adults (stroke, Parkinson's disease, and dementia), and implications for interdisciplinary clinical practice. Increased awareness of these issues may contribute to a more timely and efficient identification of older adults with dysphagia and to improve overall dysphagia management.

Study on dysphagia from 2012 to 2021: A bibliometric analysis via CiteSpace

Objectives

This study aims to review the documents on dysphagia, summarize the research direction, analyze the research hot spots and frontiers, report the research trends, and provide new ideas for future development in the field via CiteSpace.

Methods

We retrieved articles on dysphagia published between 2012 and 2021 from the Web of Science Core Collection database. We downloaded the entire data and utilized CiteSpace version 5.8.R3 (64-bit) to analyze the number of publications annually, cited journals, countries, institutions, authors, cited authors, cited references, and keywords. We visualized the data with a knowledge map, collaborative network analysis, cluster analysis, and strongest citation burst analysis.

Results

We obtained 14,007 papers with a continually increasing trend over time. The most productive country and institute in this field were the United States (4,308) and Northwestern University (236), respectively. Dysphagia (5,062) and Laryngoscope (2,812) were the most productive journals, Elizabeth Ward had the highest number of publications (84), and Logeman et al.'s article (centrality: 0.02) was the most referenced. The most common keywords were dysphagia, management, quality of life, deglutition disorder, diagnosis, aspiration, prevalence, children, outcome, and oropharyngeal dysphagia.

Conclusion

This study analyzed the current literature on dysphagia via CiteSpace and identified its research hot spots and frontiers. The prevalent global trends in dysphagia research and the growing public awareness about healthcare and quality of life suggest that research on dysphagia will gain popularity with further breakthroughs.

Association between timing of speech and language therapy initiation and outcomes among post-extubation dysphagia patients: a multicenter retrospective cohort study

Background

Post-extubation dysphagia (PED) is recognized as a common complication in the intensive care unit (ICU). Speech and language therapy (SLT) can potentially help improve PED; however, the impact of the timing of SLT initiation on persistent PED has not been well investigated. This study aimed to examine the timing of SLT initiation and its effect on patient outcomes after extubation in the ICU.

Methods

We conducted this multicenter, retrospective, cohort study, collecting data from eight ICUs in Japan. Patients aged ≥ 20 years with orotracheal intubation and mechanical ventilation for longer than 48 h, and those who received SLT due to PED, defined as patients with modified water swallowing test scores of 3 or lower, were included. The primary outcome was dysphagia at hospital discharge, defined as functional oral intake scale score < 5 or death after extubation. Secondary outcomes included dysphagia or death at the seventh, 14th, or 28th day after extubation, aspiration pneumonia, and in-hospital mortality. Associations between the timing of SLT initiation and outcomes were determined using multivariable logistic regression.

Results

A total of 272 patients were included. Of them, 82 (30.1%) patients exhibited dysphagia or death at hospital discharge, and their time spans from extubation to SLT initiation were 1.0 days. The primary outcome revealed that every day of delay in SLT initiation post-extubation was associated with dysphagia or death at hospital discharge (adjusted odds ratio (AOR), 1.09; 95% CI, 1.02–1.18). Similarly, secondary outcomes showed associations between this per day delay in SLT initiation and dysphagia or death at the seventh day (AOR, 1.28; 95% CI, 1.05–1.55), 14th day (AOR, 1.34; 95% CI, 1.13–1.58), or 28th day (AOR, 1.21; 95% CI, 1.07–1.36) after extubation and occurrence of aspiration pneumonia (AOR, 1.09; 95% CI, 1.02–1.17), while per day delay in post-extubation SLT initiation did not affect in-hospital mortality (AOR, 1.04; 95% CI, 0.97–1.12).

Conclusions

Delayed initiation of SLT in PED patients was associated with persistent dysphagia or death. Early initiation of SLT may prevent this complication post-extubation. A randomized controlled study is needed to validate these results.

AIMS

The study aimed to present a broad overview of the research conducted and to synthesize evidence of the utility of nonpharmacological interventions for pain management in medical and surgical abortions.

BACKGROUND

High-quality care for medical and surgical abortion requires pain to be managed effectively. However, women reported low satisfaction with pain management in abortion care.

DESIGN

A scoping review design was employed.

DATA SOURCES

No date limit was set. PubMed, Cochrane Library, EMBASE, Web of Science, CINAHL, PsycINFO, ProQuest and Scopus were searched in April 2021.

REVIEW METHODS

Arksey and O'Malley's framework was used. The Preferred Reporting Items for Systematic reviews and Meta-analysis extension-Scoping Reviews was followed.

RESULTS

Fifteen studies were included. The results revealed that support interventions, music therapy, acupoint stimulation and hypnotic analgesia were nonpharmacological interventions used to decrease abortion pain.

CONCLUSIONS

Clinical nurses, nurse managers and policymakers should attach full importance to the pain management in abortion and may use the study findings to guide the pain management practice.

Interventions to reduce post-traumatic stress disorder symptoms in health care professionals from 2011 to 2021: a scoping review

OBJECTIVES

This scoping review aimed to describe available interventions for decreasing (post-traumatic stress disorder) PTSD symptoms among healthcare professionals in hospital care.

METHOD

A scoping review was conducted following Arksey and O'Malley's framework. PubMed, EMBASE, Cochrane Library, CINAHL, PsycINFO, Web of Science, Scopus and ProQuest were searched for original research published in English from 2011 to 2021, on 8 July 2021. We included studies that described interventions that focused on reducing the PTSD symptoms of healthcare professionals. A narrative synthesis was adopted to synthesise the data.

RESULTS

A total of eight studies out of 2558 articles were identified. Six used a quantitative study design and two adopted qualitative methods. cognitive behavioural therapy and mindfulness-based interventions were the most commonly adopted. Most studies used a combination of different intervention strategies. Trauma-related knowledge, emotion regulation and relaxation skill training, and psychological support from peers and psychologists were three core intervention components. The duration ranged from 2 weeks to 6 months. Healthcare professionals who participated in training programmes reported both positive experiences and suggestions for the improvement of PTSD-reducing interventions in their qualitative feedback.

CONCLUSIONS

The scoping review provides a practical summary of the intervention characteristics for reducing the PTSD symptoms of healthcare professionals. Hospitals and managers could use the overview of interventions to assist healthcare professionals with PTSD symptoms. More research investigating the effects of PTSD symptom-reducing interventions for healthcare professionals with appropriate follow-up assessments is needed in the future.

Are Oropharyngeal Dysphagia Screening Tests Effective in Preventing Pneumonia?

Oropharyngeal dysphagia, a clinical condition that indicates difficulty in moving food and liquid from the oral cavity to the esophagus, has a markedly high prevalence in the elderly. The number of elderly people with oropharyngeal dysphagia is expected to increase due to the aging of the world's population. Understanding the current situation of dysphagia screening is crucial when considering future countermeasures. We report findings from a literature review including citations on current objective dysphagia screening tests: the Water Swallowing Test, Mann Assessment of Swallowing Ability, and the Gugging Swallowing Screen. Pneumonia can be predicted using the results of the screening tests discussed in this review, and the response after the screening tests is important for prevention. In addition, although interdisciplinary team approaches prevent and reduce aspiration, optimal treatment is a challenging. Intervention studies with multiple factors focusing on the elderly are needed.

Institutionalized elderly are able to detect small viscosity variations in thickened water with gum-based thickeners: should texture classifications be reviewed?

BACKGROUND

The prevalence of dysphagia is very high in institutionalized elderly. Knowledge of the rheological and sensory characteristics of the various thickeners in elderly is limited, although it has been seen that there are differences between the rheological behaviors of gum-based thickeners with different composition. Moreover, we have not found sensory studies of viscosity in institutionalized elderly. Our hypothesis was that viscosity ranges established by the scientific societies, such as the National Dysphagia Diet Task Force (NDD), seem to be very wide and individuals might be able to detect small differences within the same texture range. The objectives of our study were 1) comparing the rheological characteristics of two commercial gum-based thickeners with different composition, dissolved in water under standard conditions, and 2) perform a sensory analysis (with both adults and institutionalized elderly) to detect different viscosities within the same texture (nectar and honey).

METHODS

Two commercial thickeners based on gums (NC and RC) were studied analyzing their viscosity in water with different concentrations (shear rate: 50 s^- 1; temperature: 22-25 °C). A sensory analysis involving 26 elderly and 29 adult controls was carried out to evaluate whether differences within nectar and honey textures among gum-based thickeners could be distinguished.

RESULTS

As the shear rate increases, viscosity decreases (non-Newtonian and pseudoplastic behavior). At the same concentration, each thickener produces a different viscosity (p < 0.05). Institutionalized elderly detected viscosity differences in nectar range of 49.9 (2.5) mPa·s (p < 0.05) and 102.2 (4.7) mPa·s (p < 0.0001). They also detected viscosity differences in honey texture range of 134.6 (9.7) mPa·s (p < 0.05) y 199.3 (9.2) mPa·s (p < 0.0001). Their caregivers also detected viscosity differences in both viscosity ranges (p < 0.0001) and with greater intensity than the elderly in honey texture (p: 0.016).

CONCLUSIONS

Our results suggest that the accepted viscosity ranges by NDD for the different textures might be too wide because institutionalized elderly and their caregivers are able to discern small differences in viscosity in nectar and honey textures. Gum-based thickeners with different composition showed differences in viscosity capacity, so they are not interchangeable.

A Machine Learning-Based Screening Test for Sarcopenic Dysphagia Using Image Recognition

Background: Sarcopenic dysphagia, a swallowing disorder caused by sarcopenia, is prevalent in older patients and can cause malnutrition and aspiration pneumonia. This study aimed to develop a simple screening test using image recognition with a low risk of droplet transmission for sarcopenic dysphagia. Methods: Older patients admitted to a post-acute care hospital were enrolled in this cross-sectional study. As a main variable for the development of a screening test, we photographed the anterior neck to analyze the image features of sarcopenic dysphagia. The studied image features included the pixel values and the number of feature points. We constructed screening models using the image features, age, sex, and body mass index. The prediction performance of each model was investigated. Results: A total of 308 patients participated, including 175 (56.82%) patients without dysphagia and 133 (43.18%) with sarcopenic dysphagia. The area under the receiver operating characteristic curve (ROC-AUC), sensitivity, specificity, positive predictive value, negative predictive value, and area under the precision-recall curve (PR-AUC) values of the best model were 0.877, 87.50%, 76.67%, 66.67%, 92.00%, and 0.838, respectively. The model with image features alone showed an ROC-AUC of 0.814 and PR-AUC of 0.726. Conclusions: The screening test for sarcopenic dysphagia using image recognition of neck appearance had high prediction performance.

Preparing nurses and midwives to provide perinatal bereavement care: A systematic scoping review

OBJECTIVES

To provide a comprehensive cross-sectional overview of published studies on perinatal bereavement care education programmes developed and tested with nurses and midwives.

DESIGN

A scoping review following the Arksey and Malley's framework.

DATA SOURCES

Eight electronic databases were searched in December 2020 without restriction on language and publication date: PubMed, EMBASE, Cochrane Library, CINAHL, PsycINFO, Web of Science, Scopus and ProQuest.

REVIEW METHODS

All identified studies were reviewed by two reviewers based on the article title and abstract screening. Full-text articles were assessed according to the inclusion criteria. Original studies that reported on perinatal bereavement care education for nursing and midwifery students or clinical nurses and midwives were included.

RESULTS

Eighteen studies out of 817 articles were included. Perinatal bereavement care knowledge and skills, improvement in clinical skills in abortion care and psychological support for nurses and midwives are three core elements of the education content. Workshops and debriefing are the most frequently used formats. The duration mostly ranges from a half day to 3 days. Knowledge, confidence, satisfaction and relevant psychological variables such as posttraumatic stress symptoms are frequently used to evaluate the education programme's effectiveness. Most studies chose to use self-designed questionnaires as measurement tools. Nurses and midwives reported both positive experiences and improvement suggestions for perinatal bereavement care education programmes.

CONCLUSIONS

This scoping review highlights the benefits of implementing education programmes for preparing nurses and midwives for perinatal bereavement care in the context of universities and hospitals. Longitudinal randomized controlled trials or quasi-experiments could further investigate the effectiveness of a more enhanced perinatal bereavement care education programme with a longer intervention time using valid and reliable evaluation tools.
