OBJECTIVES: To investigate the prevalence of impaired swallowing in residents at long‐term care facilities (LTCFs) in Taiwan.

Evaluating swallowing dysfunction using a 100-ml water swallowing test.

This study used comparison with videofluoroscopic examination of swallowing (VFES) to examine the validity of a 100-ml water swallowing test (WST) in assessing swallowing dysfunction. Fifty-nine consecutive outpatients (15 females, 44 males) with clinically suspected dysphagia were enrolled in this study. Each subject underwent a 100-ml WST followed by VFES. Data was obtained on swallowing speed and signs of choking (coughing and a wet-hoarse voice). The analytical results revealed that 49 subjects had abnormal swallowing speeds (< 10 ml/s) in the 100-ml WST, and 47 of them were identified as having dysphagia by VFES. Among the ten participants with normal swallowing speed (> 10 ml/s), eight were diagnosed with dysphagia by VFES. Notably, 14 participants choked in the 100-ml WST, 11 of whom exhibited aspiration or penetration in VFES. Among the 45 participants without choking in WST, 12 displayed aspiration or penetration in VFES. The sensitivity of swallowing speed in detecting the swallowing dysfunction was 85.5%, and the specificity was 50%. Moreover, the sensitivity of using choking or wet-horse voice in the 100-ml WST as the sole factor for predicting the presence of aspiration was 47.8%, while the specificity was 91.7%. Therefore, this study concluded that swallowing speed is a sensitive indicator for identifying patients at risk for swallowing dysfunction. Moreover, choking in the 100-ml WST may be a potential specific indicator for followup aspiration.

Edinburgh Feeding Evaluation in Dementia (EdFED) scale: cross-cultural validation of the Chinese version

AIM This paper is a report of an assessment of the construct validity of the Chinese version of the Edinburgh Feeding Evaluation in Dementia scale. BACKGROUND The Edinburgh Feeding Evaluation in Dementia scale has previously been translated and back-translated and to determine the equality of the Chinese and English versions. However, the construct validity of the Chinese version has not been investigated. METHODS Participants (n = 477) were selected from residents with dementia in licensed long-term care facilities in Taiwan in 2006-2007. Data collectors received training before observing feeding for 2 days during lunch and dinner. Data were analysed using principal component analysis, Mokken scaling and correlation. FINDINGS A two-factor structure was demonstrated for the 11 items of the Chinese version of the scale and six items conformed to a Mokken scale. The Chinese version of the scale correlated with external constructs such as weight and body mass index, as predicted by the unmet needs model. CONCLUSION A confirmatory factor analysis is needed to confirm that the Chinese version measures the same qualities, in the same proportions, and with the same factor structure as the original Edinburgh Feeding Evaluation in Dementia scale.

Effectiveness of a self-care program in improving symptom distress and quality of life in congestive heart failure patients: a preliminary study.

Background:Prevalence of heart failure is increasing among older adults. Most heart failure patients experience distressing symptoms that lead to decreased physical functioning, poor quality of life, and a high incidence of rehospitalization. Health education about heart failure self-care (HFSC) is very important during hospitalization for these patients. However, lack of ongoing follow-up after discharge makes evaluation and disease management difficult. This is a significant problem in Taiwan. Purpose:This study was undertaken to determine if participants with heart failure who were managed under the HFSC program had fewer distressing symptoms, better functional status, improved quality of life, and reduced hospital and emergency readmission rates compared with control group participants. Methods:This study used a quasi-experimental design with a control group that received usual care and an intervention group that received usual care plus the HFSC program. Twenty-seven participants were recruited from 2 cardiac general wards at 1 medical center in Taipei City, Taiwan, and were randomized into intervention (n = 14) and control (n = 13) groups. Results:After 3 months, there were significant differences in symptom distress (p < .01), 6-minute walk test results (p < .01), and quality of life (using Short Form 36, Taiwan version, p < .05) between the HFSC and control groups but no significant differences in hospital readmission and emergency department visits. Conclusions/Implications for Practice:The HFSC program for patients with heart failure improved their heart failure symptoms and resulted in increased functional status and better quality of life. HFSC is a workable program in the clinical environment. Advanced nurse practitioners can use HFSC methods and principles to provide improved education and follow-up to heart failure patients.

Comparison of the efficacy of aroma-acupressure and aromatherapy for the treatment of dementia-associated agitation

BackgroundOne of the most common symptoms observed in patients with dementia is agitation, and several non-pharmacological treatments have been used to control this symptom. However, because of limitations in research design, the benefit of non-pharmacological treatments has only been demonstrated in certain cases. The purpose of this study was to compare aroma-acupressure and aromatherapy with respect to their effects on agitation in patients with dementia.MethodsIn this experimental study, the participants were randomly assigned to three groups: 56 patients were included in the aroma-acupressure group, 73 patients in the aromatherapy group, and 57 patients in the control group who received daily routine as usual without intervention. The Cohen-Mansfield Agitation Inventory (CMAI) scale and the heart rate variability (HRV) index were used to assess differences in agitation. The CMAI was used in the pre-test, post-test and post-three-week test, and the HRV was used in the pre-test, the post-test and the post-three-week test as well as every week during the four-week interventions.ResultsThe CMAI scores were significantly lower in the aroma-acupressure and aromatherapy groups compared with the control group in the post-test and post-three-week assessments. Sympathetic nervous activity was significantly lower in the fourth week in the aroma-acupressure group and in the second week in the aromatherapy group, whereas parasympathetic nervous activity increased from the second week to the fourth week in the aroma-acupressure group and in the fourth week in the aromatherapy group.ConclusionsAroma-acupressure had a greater effect than aromatherapy on agitation in patients with dementia. However, agitation was improved in both of the groups, which allowed the patients with dementia to become more relaxed. Future studies should continue to assess the benefits of aroma-acupressure and aromatherapy for the treatment of agitation in dementia patients.Trial registrationChiCTR-TRC-14004810; Date of registration: 2014/6/12

Evaluation of the psychometric properties and the clinical feasibility of a Chinese version of the Doloplus-2 scale among cognitively impaired older people with communication difficulty

BACKGROUND Several behaviourally observed tools have been developed to assess pain among cognitively impaired older people with communication difficulty. However, no adequate pain observation instrument is available for this group in Taiwan. OBJECTIVE The study was undertaken to translate the French version of the Doloplus-2 scale into Chinese and to evaluate the psychometric properties and the clinical feasibility of the translated instrument. DESIGN A prospective, descriptive design was used. SETTINGS Five dementia special care units in the Northern Taiwan were used. PARTICIPANTS Two hundred and forty-one residents with dementia and 14 registered nurses in charge of these residents were recruited. METHODS The Doloplus-2 scale was translated into Chinese using the back-translation technique and pilot testing was performed to determine the comprehensibility and the initial psychometric characteristics. Internal consistency and inter-rater reliability were evaluated by Cronbachs alpha and intra-class correlation coefficient, respectively. Based on the known correlated validity model, the association between C-Doloplus-2 and empirically supported correlates of pain such as the past pain history, the presence of pain related condition, functional disability, agitation and depression were examined using Pearsons correlation coefficient for validating the construct validity. Furthermore, factor structure was investigated using Principal Components Analysis. RESULTS The internal consistency was adequate for the total scale (alpha 0.74) and the subscales (alpha range 0.67-0.87). The intra-class correlation coefficient of the total scale was 0.81 and of the subscales ranged from 0.60 to 0.81. The association between pain latent variable and disability or depression was demonstrated, partially supporting the construct validity. Three factors were extracted to confirm the original three-dimensional structure perfectly, accounting 65% of the total variance. CONCLUSIONS The psychometric qualities of Chinese Doloplus-2 were supported. Further research is needed to assess the clinical value of the translated scale performed in the institutions.

Effects of primary caregiver participation in vestibular rehabilitation for unilateral neglect patients with right hemispheric stroke: a randomized controlled trial.

Introduction The current study aims to investigate the effects of primary caregiver participation in vestibular rehabilitation (VR) on improving the measures of neglect, activities of daily living (ADL), balance, and falls of unilateral neglect (UN) patients. Methods This study is a single-blind randomized controlled trial. Both experimental (n = 24) and control groups (n = 24) received conventional rehabilitation. The experimental group undertook VR for a month. During the first and second weeks, a registered nurse trained the experimental group in VR. The primary caregivers in the experimental group supervised and guided their patients in VR during the third and fourth weeks. The outcome measures were neglect, ADL, balance, and falls. Results The two groups of UN patients showed a significant improvement in neglect, ADL, and balance over time. Based on the generalized estimating equations model, an interaction was observed between groups and times. Significant interactions were observed between the VR group at days 14 and 28 in the areas of neglect, ADL, and balance. No significant difference was observed between the two groups in the number of falls. Conclusion Neglect, ADL, and balance among UN patients with right hemispheric stroke can be improved through the participation of primary caregivers in VR. Trained informal caregivers were recommended to provide VR guidance and supervision to patients who suffer from UN.

Single ability among activities of daily living as a predictor of agitation

AIMS The aims of this study were to investigate whether the interaction effect between restraint and functional ability, and single ability during activities of daily living can predict agitation among residents with dementia. BACKGROUND Agitated behaviour is one of the most common symptoms of dementia and might endanger the patients themselves, caregivers and institutions. However, the prevalence of problem behaviours and its associated factors at long-term care facilities in Taiwan are less understood. DESIGN A direct observation was used to observe the agitated behaviours of residents with dementia in special care units. METHODS Residents of dementia special care units who were diagnosed with dementia in eight long-term care facilities were recruited. Measurements included: demographic data, the Barthel Index, the Mini-Mental State Examination and the Cohen-Mansfield Agitation Inventory. RESULTS The number of subjects who were identified with problem behaviours was 163 (43.5%). Significant differences in sex, being restrained, restrained time, age, family visits, functional status and mental status were found between the agitated and non-agitated groups. However, mental status, family visits, walking ability, being restrained and getting in and off toilet were five independent factors associated with agitated behaviours after controlling for all other factors. CONCLUSIONS It is recommended that strategies be constructed to encourage the family to periodically visit older residents and to develop restraint-free environments in long-term care facilities. RELEVANCE TO CLINICAL PRACTICE Residents with dementia require significant daily living support and behaviour management as their illness progress.
