The effect of touch on nutritional intake of chronic organic brain syndrome patients

A systematic review and multivariate meta-analysis of the physical and mental health benefits of touch interventions

Receiving touch is of critical importance, as many studies have shown that touch promotes mental and physical well-being. We conducted a pre-registered (PROSPERO: CRD42022304281) systematic review and multilevel meta-analysis encompassing 137 studies in the meta-analysis and 75 additional studies in the systematic review (n = 12,966 individuals, search via Google Scholar, PubMed and Web of Science until 1 October 2022) to identify critical factors moderating touch intervention efficacy. Included studies always featured a touch versus no touch control intervention with diverse health outcomes as dependent variables. Risk of bias was assessed via small study, randomization, sequencing, performance and attrition bias. Touch interventions were especially effective in regulating cortisol levels (Hedges' g = 0.78, 95% confidence interval (CI) 0.24 to 1.31) and increasing weight (0.65, 95% CI 0.37 to 0.94) in newborns as well as in reducing pain (0.69, 95% CI 0.48 to 0.89), feelings of depression (0.59, 95% CI 0.40 to 0.78) and state (0.64, 95% CI 0.44 to 0.84) or trait anxiety (0.59, 95% CI 0.40 to 0.77) for adults. Comparing touch interventions involving objects or robots resulted in similar physical (0.56, 95% CI 0.24 to 0.88 versus 0.51, 95% CI 0.38 to 0.64) but lower mental health benefits (0.34, 95% CI 0.19 to 0.49 versus 0.58, 95% CI 0.43 to 0.73). Adult clinical cohorts profited more strongly in mental health domains compared with healthy individuals (0.63, 95% CI 0.46 to 0.80 versus 0.37, 95% CI 0.20 to 0.55). We found no difference in health benefits in adults when comparing touch applied by a familiar person or a health care professional (0.51, 95% CI 0.29 to 0.73 versus 0.50, 95% CI 0.38 to 0.61), but parental touch was more beneficial in newborns (0.69, 95% CI 0.50 to 0.88 versus 0.39, 95% CI 0.18 to 0.61). Small but significant small study bias and the impossibility to blind experimental conditions need to be considered. Leveraging factors that influence touch intervention efficacy will help maximize the benefits of future interventions and focus research in this field.

Self-feeding dependence incidence and predictors among nursing home residents: Findings from a 5 year retrospective regional study

The aim of this regionally-based, retrospective study was to describe the incidence of self-feeding dependence and predictors among elderly patients admitted from 2008 to 2013 to 105 Italian nursing homes. Data reported in a regional database collected at the time of nursing home admission and every 6 months up to the resident's death were accessed. The self-feeding degree of dependence was the dependent variable; at the individual and nursing home levels, explanatory variables were those collected at nursing home admission and every 6 months. The structural equation model and the ordinal polynomial logit regression analysis were performed. A total of 13 175 records of residents when admitted to the nursing home and their following 69 341 records, were included. At the time of nursing home admission, 6496 residents (49.3%) reported a certain degree of dependence in self-feeding and showed slight worsening in their dependence every 6 months. At the individual level, the increased functional dependence raised the proportional odds ratios of approximately 4.36 times of an increased dependence in self-feeding; the degree of cognitive impairment, the lack of social interactions, the occurrence of pressure sores, comorbidities, as well as the clinical instability and time all raised the risk of self-feeding dependence progression. At the nursing home level, an increased number of beds emerged as a factor also increasing the proportional odds of dependence in self-feeding. Factors affecting self-feeding dependence are multi-faceted at the individual and at the nursing home levels.

Validation and psychometric properties of the Russian version of the Touch Experiences and Attitudes Questionnaire (TEAQ-37 Rus)

It has been demonstrated that nurturing and affiliative touch is essential for human emotional and physical well-being throughout our entire life. Within the last 30 years a system of low-threshold mechanosensitive C fibers innervating the hairy skin was discovered and described; this system is hypothesized to represent the neurobiological substrate for the affective and rewarding properties of touch. This discovery opens new perspectives for multidisciplinary research of the role of affiliative social touch in health and disease, and calls for establishing novel psychometric tools assessing individual differences in the domain of affective touch. The main objective of the study was to construct and validate a Russian version of the Touch Experiences and Attitudes Questionnaire (TEAQ), a self-report measure recently developed to quantify individual experience and attitude to social and affective touch. A pool of 117 items was translated into Russian and all the items were assessed for appropriateness for Russian culture (232 participants). After exploring the factor structure (468 participants), we composed a 37-item questionnaire (TEAQ-37 Rus) characterized by good reliability and a clear 5-factor structure, covering the aspects of attitude to intimate touch, attitude to friendly touch, attitude to self-care, current intimate touch experiences, and childhood touch experiences. Confirmatory factor analysis (551 participants) has demonstrated good consistency and reliability of the 5-factor structure of the TEAQ-37 Rus. Cross-validation research demonstrated moderate positive correlations between predisposition to social touch and emotional intelligence; positive correlations with extraversion and openness facets of the Big Five personality model were also found. As predicted, participants with higher TEAQ-37 Rus scores rated all observed kinds of touch as more pleasant, with a particular preference for slow touch. We anticipate that this questionnaire will be a valuable tool for researchers of social touch, touch perception abnormalities, and the importance of touch experiences for emotional and mental health.

Interventions maintaining eating Independence in nursing home residents: a multicentre qualitative study

Background

Despite 32 years of research and 13 reviews published in the field, no intervention can be considered a gold standard for maintaining eating performance among residents with dementia. The study aim was to highlight the interventions derived from tacit knowledge and offered daily in assisting eating by healthcare professionals (HCPs) in nursing homes (NHs).

Method

A multicentre descriptive qualitative study was performed in 2017. Thirteen NHs admitting residents with moderate/severe functional dependence in eating mainly due to dementia, were approached. A purposeful sample of 54 HCPs involved on a daily basis in assisting residents during mealtime were interviewed in 13 focus groups. Data analysis was conducted via qualitative content analysis.

Results

The promotion and maintenance of eating performance for as long as possible is ensured by a set of interventions targeting three levels: (a) environmental, by ‘Ritualising the mealtime experience by creating a controlled stimulated environment’; (b) social, by ‘Structuring effective mealtime social interactions’; and (c) individual, by ‘Individualising eating care’ for each resident.

Conclusions

In NHs, the eating decline is juxtaposed with complex interventions regulated on a daily basis and targeting the environment, the social interactions, and the residents’ needs. Several interventions that emerged as effective, according to the experience of participants, have never been documented before; while others are in contrast to the evidence documented. This suggests the need for further studies in the field; as no conclusions regarding the best interventions have been established to date.

Construction and Validation of the Touch Experiences and Attitudes Questionnaire (TEAQ): A Self-report Measure to Determine Attitudes Toward and Experiences of Positive Touch

Despite growing interest in the beneficial effects of positive touch experiences throughout our lives, and individual differences in how these experiences are perceived, there is not yet available a contemporary self-report measure of touch experiences and attitudes, for which the factor structure has been validated. This article describes four studies carried out during the construction and validation of the Touch Experiences and Attitudes Questionnaire (TEAQ). The original TEAQ, containing 117 items relating to positive touch experiences was systematically constructed. Principal component analysis reduced this measure to 57 items and identified six components relating to touch experiences during childhood and adult experiences relating to current intimate touch and touch with friends and family. Three attitudinal components were identified relating to attitude to intimate touch, touch with unfamiliar people, and self-care. The structure of this questionnaire was confirmed through confirmatory factor analysis carried out on data obtained from a second sample. Good concurrent and predictive validity of the TEAQ compared to other physical touch measures currently available was identified. Known-group validity in terms of gender, marital status and age was determined, with expected group differences identified. This study demonstrates the TEAQ to have good face validity, internal consistency, construct validity in terms of discriminant validity, known-group validity and convergent validity, and criterion-related validity in terms of predictive validity and concurrent validity. We anticipate this questionnaire will be a valuable tool for the field of physical touch research.

Environmental and behavioural modifications for improving food and fluid intake in people with dementia

BACKGROUND

Weight loss, malnutrition and dehydration are common problems for people with dementia. Environmental modifications such as, change of routine, context or ambience at mealtimes, or behavioural modifications, such as education or training of people with dementia or caregivers, may be considered to try to improve food and fluid intake and nutritional status of people with dementia.

OBJECTIVES

Primary: To assess the effects of environmental or behavioural modifications on food and fluid intake and nutritional status in people with dementia. Secondary: To assess the effects of environmental or behavioural modifications in connection with nutrition on mealtime behaviour, cognitive and functional outcomes and quality of life, in specific settings (i.e. home care, residential care and nursing home care) for different stages of dementia. To assess the adverse consequences or effects of the included interventions.

SEARCH METHODS

We searched the Specialized Register of Cochrane Dementia and Cognitive Improvement (ALOIS), MEDLINE, Eembase, PsycINFO, CINAHL, ClinicalTrials.gov and the World Health Organization (WHO) portal/ICTRP on 17 January 2018. We scanned reference lists of other reviews and of included articles.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) investigating interventions designed to modify the mealtime environment of people with dementia, to modify the mealtime behaviour of people with dementia or their caregivers, or both, with the intention of improving food and fluid intake. We included people with any common dementia subtype.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, extracted data and assessed the risk of bias of included trials. We assessed the quality of evidence for each outcome using the GRADE approach.

MAIN RESULTS

We included nine studies, investigating 1502 people. Three studies explicitly investigated participants with Alzheimer's disease; six did not specify the type of dementia. Five studies provided clear measures to identify the severity of dementia at baseline, and overall very mild to severe stages were covered. The interventions and outcome measures were diverse. The overall quality of evidence was mainly low to very low.One study implemented environmental as well as behavioural modifications by providing additional food items between meals and personal encouragement to consume them. The control group received no intervention. Differences between groups were very small and the quality of the evidence from this study was very low, so we are very uncertain of any effect of this intervention.The remaining eight studies implemented behavioural modifications.Three studies provided nutritional education and nutrition promotion programmes. Control groups did not receive these programmes. After 12 months, the intervention group showed slightly higher protein intake per day (mean difference (MD) 0.11 g/kg, 95% confidence interval (CI) -0.01 to 0.23; n = 78, 1 study; low-quality evidence), but there was no clear evidence of a difference in nutritional status assessed with body mass index (BMI) (MD -0.26 kg/m² favouring control, 95% CI -0.70 to 0.19; n = 734, 2 studies; moderate-quality evidence), body weight (MD -1.60 kg favouring control, 95% CI -3.47 to 0.27; n = 656, 1 study; moderate-quality evidence), or score on Mini Nutritional Assessment (MNA) (MD -0.10 favouring control, 95% CI -0.67 to 0.47; n = 656, 1 study; low-quality evidence). After six months, the intervention group in one study had slightly lower BMI (MD -1.79 kg/m² favouring control, 95% CI -1.28 to -2.30; n = 52, 1 study; moderate-quality evidence) and body weight (MD -8.11 kg favouring control, 95% CI -2.06 to -12.56; n = 52, 1 study; moderate-quality evidence). This type of intervention may have a small positive effect on food intake, but little or no effect, or a negative effect, on nutritional status.Two studies compared self-feeding skills training programmes. In one study, the control group received no training and in the other study the control group received a different self-feeding skills training programme. For both comparisons the quality of the evidence was very low and we are very uncertain whether these interventions have any effect.One study investigated general training of nurses to impart knowledge on how to feed people with dementia and improve attitudes towards people with dementia. Again, the quality of the evidence was very low so that we cannot be certain of any effect.Two studies investigated vocal or tactile positive feedback provided by caregivers while feeding participants. After three weeks, the intervention group showed an increase in calories consumed per meal (MD 200 kcal, 95% CI 119.81 to 280.19; n = 42, 1 study; low-quality evidence) and protein consumed per meal (MD 15g, 95% CI 7.74 to 22.26; n = 42, 1 study; low-quality evidence). This intervention may increase the intake of food and liquids slightly; nutritional status was not assessed.

AUTHORS' CONCLUSIONS

Due to the quantity and quality of the evidence currently available, we cannot identify any specific environmental or behavioural modifications for improving food and fluid intake in people with dementia.

Social Touch Technology: A Survey of Haptic Technology for Social Touch

This survey provides an overview of work on haptic technology for social touch. Social touch has been studied extensively in psychology and neuroscience. With the development of new technologies, it is now possible to engage in social touch at a distance or engage in social touch with artificial social agents. Social touch research has inspired research into technology mediated social touch, and this line of research has found effects similar to actual social touch. The importance of haptic stimulus qualities, multimodal cues, and contextual factors in technology mediated social touch is discussed. This survey is concluded by reflecting on the current state of research into social touch technology, and providing suggestions for future research and applications.

Effectiveness of interventions to indirectly support food and drink intake in people with dementia: Eating and Drinking Well IN dementiA (EDWINA) systematic review

Background

Risks and prevalence of malnutrition and dehydration are high in older people but even higher in older people with dementia. In the EDWINA (Eating and Drinking Well IN dementiA) systematic review we aimed to assess effectiveness of interventions aiming to improve, maintain or facilitate food/drink intake indirectly, through food service or dining environment modification, education, exercise or behavioural interventions in people with cognitive impairment or dementia (across all settings, levels of care and support, types and degrees of dementia).

Methods

We comprehensively searched Medline and twelve further databases, plus bibliographies, for intervention studies with ≥3 cognitively impaired adult participants (any type/stage). The review was conducted with service user input in accordance with Cochrane Collaboration’s guidelines. We duplicated assessment of inclusion, data extraction, and validity assessment, tabulating data. Meta-analysis (statistical pooling) was not appropriate so data were tabulated and synthesised narratively.

Results

We included 56 interventions (reported in 51 studies). Studies were small and there were no clearly effective, or clearly ineffective, interventions. Promising interventions included: eating meals with care-givers, family style meals, soothing mealtime music, constantly accessible snacks and longer mealtimes, education and support for formal and informal care-givers, spaced retrieval and Montessori activities, facilitated breakfast clubs, multisensory exercise and multicomponent interventions.

Conclusions

We found no definitive evidence on effectiveness, or lack of effectiveness, of specific interventions but studies were small and short term. A variety of promising indirect interventions need to be tested in large, high-quality RCTs, and may be approaches that people with dementia and their formal or informal care-givers would wish to try.

Trial registration

The systematic review protocol was registered (CRD42014007611) and is published, with the full MEDLINE search strategy, on Prospero (http://www.crd.york.ac.uk/PROSPERO/display_record.asp?ID=CRD42014007611).

The Neurobiology Shaping Affective Touch: Expectation, Motivation, and Meaning in the Multisensory Context

Inter-individual touch can be a desirable reward that can both relieve negative affect and evoke strong feelings of pleasure. However, if other sensory cues indicate it is undesirable to interact with the toucher, the affective experience of the same touch may be flipped to disgust. While a broad literature has addressed, on one hand the neurophysiological basis of ascending touch pathways, and on the other hand the central neurochemistry involved in touch behaviors, investigations of how external context and internal state shapes the hedonic value of touch have only recently emerged. Here, we review the psychological and neurobiological mechanisms responsible for the integration of tactile “bottom–up” stimuli and “top–down” information into affective touch experiences. We highlight the reciprocal influences between gentle touch and contextual information, and consider how, and at which levels of neural processing, top-down influences may modulate ascending touch signals. Finally, we discuss the central neurochemistry, specifically the μ-opioids and oxytocin systems, involved in affective touch processing, and how the functions of these neurotransmitters largely depend on the context and motivational state of the individual.

Somatosensory pleasure circuit: from skin to brain and back

The skin senses serve a discriminative function, allowing us to manipulate objects and detect touch and temperature, and an affective/emotional function, manifested as itch or pain when the skin is damaged. Two different classes of nerve fibre mediate these dissociable aspects of cutaneous somatosensation: (i) myelinated A-beta and A-delta afferents that provide rapid information about the location and physical characteristics of skin contact; and (ii) unmyelinated, slow-conducting C-fibre afferents that are typically associated with coding the emotional properties of pain and itch. However, recent research has identified a third class of C-fibre afferents that code for the pleasurable properties of touch - c-tactile afferents or CTs. Clinical application of treatments that target pleasant, CT-mediated touch (such as massage therapy) could, in the future, provide a complementary, non-pharmacological means of treating both the physical and psychological aspects of chronic skin conditions such as itch and eczema.

Effect of a brief seated massage on nursing student attitudes toward touch for comfort care

BACKGROUND

While massage has been removed from nursing curricula, studies have reported massage as safe and effective for stress reduction, relaxation, pain relief, fatigue, and quality of life.

OBJECTIVE

To compare the efficacy of two intensities of touch administered during two seated massages on the attitudes of nursing students toward touch for their self-care and patient care.

PARTICIPANTS

Nursing students who volunteered gave institutional review board-approved written informed consent to undergo massage by a licensed massage therapist.

SETTINGS/LOCATION

A private room adjacent to the nursing lab in a school of nursing.

INTERVENTION

Brief seated massages of differing intensities. Each participant received low-intensity and high-intensity touch in a two-block, randomized order, within-subjects design. Linear mixed models nested within subject and random intercept analyses were used to test hypotheses in this two-treatment, two-sequence, two-period crossover design.

OUTCOME MEASURES

Health questionnaires/visual analogue scales pertaining to physical/affective/and attitudinal status were completed before and after each massage.

RESULTS

Twenty-nine participants (93% female, 83% single) completed the study. Before massage, the optimal intensity of touch anticipated for self-comfort was 6.6 (0=no pressure;10=most intense pressure imaginable). The mean touch intensities were 6.7 for high-intensity massage and 0.5 for low-intensity (p<0.001). The overall percentage differences (feeling better or worse) following massage were as follows: low intensity, 37.5% better; high intensity, 62.7% better (p<0.001). Significantly more improvement was reported for energy, pain, stress, and feeling physically uptight after high-intensity compared with low-intensity (p<0.03). Participants were more likely to both receive touch for self-care and provide touch for patient care after experiencing high- versus low-intensity massage (p<0.01).

CONCLUSIONS

High-intensity seated massage was more efficacious than low-intensity massage and positively influenced nursing student attitudes toward the inclusion of massage in self-care/patient care. The role of touch for self-care/patient care in the nursing curricula merits reconsideration.

Improving medication adherence by using practitioner nonverbal techniques: a field experiment on the effect of touch

Though the positive effect of touch on compliance has been widely reported in the social psychology literature, a new evaluation has been made in a health setting. Six general practitioners were instructed to touch (or not) their patients on the forearm for 1-2 s. Patients who suffered from mild pharyngitis were solicited by the practitioners at the end of the consultation for a verbal promise to take the antibiotic medication as prescribed. One week later, patients were contacted at home to determine the number of pills that had been taken and to evaluate the practitioner. Touch increased medication adherence in both male and female patients, but was associated with a greater increase in male patients. It was also found that practitioners were perceived to be more concerned about their patients by those in the touch condition. Practitioner competence appeared to be slightly higher in the touch condition. The theoretical implications of this positive effect of tactile contact are discussed and the practical interest for practitioners is highlighted, showing how this nonverbal technique could help them to increase the medication adherence of their patients.

The effect of a practitioner's touch on a patient's medication compliance

Although the positive effect of touch on compliance has been widely found in the literature, a new evaluation has been carried out in a health setting. Four general practitioners were instructed to slightly touch (or not) their adult patients who suffered from a pharyngitis when they asked them for a verbal promise to take the prescribed antibiotic medication. One week later, patients were solicited at home to evaluate the number of tablets that were taken. Greater medication compliance was found in the touch condition.

Teaching Massage to Nursing Students of Geriatrics Through Active Learning

The use of massage in nursing practice has declined through the years in favor of high-tech interventions. This article describes a project using active learning to teach nursing students massage with dementia residents in assisted living. Students participated in a workshop to practice basic relaxation massage techniques with the guidance of their clinical instructor and then provided massages to resident volunteers. Afterward, students discussed their experience and completed a resident assessment form. The students requested more such activities, and the residents and facility management invited the students to return for another session. The instructor observed growth in the students' assessment skills and in their confidence. Use of massage to teach nursing students how to care for and relate to older adults with cognitive impairment is recommended. Further research is needed on the use of massage as an active learning method for nursing students in long-term care.

The science of interpersonal touch: an overview

Surprisingly little scientific research has been conducted on the topic of interpersonal touch over the years, despite the importance of touch in our everyday social interactions from birth through to adulthood and old age. In this review, we critically evaluate the results of the research on this topic that have emerged from disciplines, such as cognitive and social psychology, neuroscience, and cultural anthropology. We highlight some of the most important advances to have been made in our understanding of this topic: For example, research has shown that interpersonal tactile stimulation provides an effective means of influencing people's social behaviors (such as modulating their tendency to comply with requests, in affecting people's attitudes toward specific services, in creating bonds between couples or groups, and in strengthening romantic relationships), regardless of whether or not the tactile contact itself can be remembered explicitly. What is more, interpersonal touch can be used to communicate emotion in a manner similar to that demonstrated previously in vision and audition. The recent growth of studies investigating the potential introduction of tactile sensations to long-distance communication technologies (by means of mediated or 'virtual' touch) are also reviewed briefly. Finally, we highlight the synergistic effort that will be needed by researchers in different disciplines if we are to develop a more complete understanding of interpersonal touch in the years to come.

Feeding difficulty in older adults with dementia

AIMS AND OBJECTIVES

To use concept analysis to identify characteristics of feeding difficulty and its antecedents and consequences that provide direction for assessment and management.

BACKGROUND

Feeding difficulty is often recognised as a common problem for older adults and is associated with weight loss, poor nutrition and risk for aspiration pneumonia. The cognitive impairment found in persons with dementia impairs the ability of these adults to complete motor and perceptual tasks required for eating and often prevent the older adult from accepting help with feeding from caregivers.

DESIGN

Systematic review.

METHODS

In 2006, literature searches using keywords (feeding, eating, nutrition, malnutrition, feeding assessment, dementia, ageing and concept analysis, dementia and feeding and excluding enteral feeding, tube feedings, PEG and enteral nutrition) were done in Medline, CINHAL, AGELINE and Social Science Full Text. Seventy relevant articles in English were found. After a review of the relevant articles, concept analysis was used to develop a definition of feeding difficulty, its defining characteristics and to delineate feeding difficulty from its antecedents and consequences.

RESULTS

Feeding difficulties arise at the interface between the caregiver strategies to assist the older adult with getting food into the mouth and chewing and swallowing food. A model of feeding difficulty delineates the antecedents and consequences of feeding difficulties.

CONCLUSIONS

The conceptual model of feeding difficulties provides a strong and clear organising structure for research that can be used to developed evidence based guidelines for practice.

RELEVANCE TO CLINICAL PRACTICE

The conceptual model provides directions for assessment of feeding difficulties and their antecedents. The model can be used to identify interventions that address antecedents of feeding difficulty (risk factors) and different types of feeding difficulties.

Massage and touch for dementia

BACKGROUND

Massage and touch have been suggested as a non-pharmacological alternative or supplement to other treatments offered in order to reduce or manage a range of conditions associated with dementia such as anxiety, agitated behaviour and depression. It has also been suggested that massage and touch may counteract cognitive decline.

OBJECTIVES

To assess the effects of a range of massage and touch therapies on conditions associated with dementia, such as anxiety, agitated behaviour and depression, identify any adverse effects, and provide recommendations about future trials.

SEARCH STRATEGY

We identified trials from a search of the Specialized Register of the Cochrane Dementia and Cognitive Improvement Group on 12 July 2005 using the terms massage, reflexology, touch and shiatsu. This Register contains records from all major healthcare databases and many ongoing trials databases and is updated regularly. In addition, general and specific literature databases were searched and patient and therapist organizations contacted.

SELECTION CRITERIA

Randomized controlled trials (RCTs) in which a massage or touch intervention was given to persons suffering from dementia of any type, compared with other treatments or no treatment, and in which effect parameters included measures of behavioural problems, caregiver burden, emotional distress or cognitive abilities, were eligible for inclusion. Furthermore, we employed a set of minimal methodological quality criteria as a selection filter.

DATA COLLECTION AND ANALYSIS

We identified 34 references in the initial searches. Of these, seven were actual or possible RCTs, but only two were found to meet the requirements of the set of minimal methodological criteria.

MAIN RESULTS

The very limited amount of reliable evidence available is in favour of massage and touch interventions for problems associated with dementia. However, this evidence addresses only two specific applications: hand massage for the immediate or short-term reduction of agitated behaviour, and the addition of touch to verbal encouragement to eat for the normalization of nutritional intake. The existing evidence does not support general conclusions about the effect or possible side effects of such interventions. No severe side effects were identified.

AUTHORS' CONCLUSIONS

Massage and touch may serve as alternatives or complements to other therapies for the management of behavioural, emotional and perhaps other conditions associated with dementia. More research is needed, however, to provide definitive evidence about the benefits of these interventions.

The Effect of A Feeding Skills Training Program for Nursing Assistants Who Feed Dementia Patients in Taiwanese Nursing Homes

A quasi-experimental 2-group repeated-measures design was used to test the impact of a feeding skills training program on 67 nursing assistants (treatment group n = 31; control group n = 36) regarding their knowledge, attitudes, perceived behavior control, intentions, and behaviors in feeding dementia patients. The treatment group received a feeding skills training program. Nursing assistants' knowledge, attitudes, perceived behavior control, and intentions were measured before (Pretest) and after the program (Posttest 1), and again 4 weeks later (Posttest 2). Nursing assistants (treatment group n = 20; control group n = 16) and the same number of dementia patients were measured on feeding behaviors during mealtimes before and after the training. The treatment group had significantly more knowledge (P < .001), greater intention to feed (P = .05), and better behaviors toward feeding dementia patients (P = .009) than the control group. There were no significant differences between the groups in attitude (P = .85), intention beliefs (P = .11) or perceived behavior control (P = .99). Thus, the intervention was effective at changing knowledge, intention, and behaviors among nursing assistants.

Feeding and hydration issues for older adults with dementia

All cultures dictate the need to feed the hungry and create rituals for almost every life passage around the consumption of food and beverage. Yet, in old age and among those who cannot advocate for themselves, mealtime is medicalized and demoted to an insignificant event without dignity or regard for individualized needs. Attention must be paid to not only what people eat, but how they eat, and how they are supported in that process. Kayser-Jones summarized the extensive findings of several ethnographic studies in nursing homes by noting the multi-factorial issues involved in delivering excellent care to all residents, especially those lacking an advocate. Her findings exposed how lack of staff education, inadequate staffing and supervision, disregard for personal and cultural preferences, lack of assessment for comorbid health problems, intake of food and fluids, dysphagia, and oral health problems all contributed to malnutrition and dehydration among the residents studied. This seminal set of studies, along with Dr. Kayser-Jones' testimony in US Congressional hearings directly affected the design of federal regulatory protocols to address malnutrition and dehydration. In an attempt to increase the number of staff available to assist at meals, the Centers for Medicare and Medicaid issued a change in regulations on Sept. 26, 2003, allowing reimbursement for staff trained for a total of 8 hours to act as feeding assistants. This change is intended to, "provide more residents with help in eating and drinking and reduce the incidence of unplanned weight loss and dehydration". Although seen as answering some of the staffing ratio issues at meal times,this rule change has been criticized for not addressing the complexities of resident needs at meal times. Although offering food and fluid is time-consuming and requires special knowledge of physiological changes and empathy for persons whose behavior might be objectionable at times, it may be one of the few times during the day that the individual with dementia receives normalized social interaction. Thus, as in the care of all vulnerable persons with dementia, whether at home or in an institution, perhaps the greatest challenge and need is for nurses and other caregivers to provide a social environment that promotes individual dignity and comfort.

A blueprint-based case study analysis of nutrition services provided in a midterm care facility for the elderly

Ensuring nutritionally adequate food intake in institutions is a complex and important challenge for dietitians. To tackle this problem, we argue that dietitians need to adopt a systematic, integrative, and patient-centered approach to identify and manage more effectively organizational determinants of the quality of food intake under their control. In this study, we introduce such an approach, the blueprint-based case study, that we applied in the context of a midterm care facility for elderly patients. Data gathered through interviews and field observations were used to develop, from the perspective of key patient encounters, detailed representations of the food, nutrition, and nursing activities necessary to ensure adequate food intake. These service "blueprints" were developed to illustrate all activities that might potentially impact on the nutritional, sensory, functional, and social quality of patients' meals. They were also used as roadmaps to develop a case study analysis in which critical areas were identified and opportunities for improvement put forth, while considering services' resources and priorities. By providing a precise, objective, yet comprehensive mapping of the service operations and management, the blueprint-based case study approach represents a valuable tool to determine the optimal allocation of resources to insure nutritionally adequate food intake to patients.

Direct and indirect effects of everyday emotions on food intake of elderly patients in institutions

BACKGROUND

Decreased food intake is an important risk factor for malnutrition, which is highly prevalent among geriatric patients. The emotional nature of the hospitalization experience and the complex organizational setting involved in meal production and delivery services in institutions increase the risk for decreased food intake. Everyday emotions are known to have a particularly strong influence on decision-making and behavior in the elderly, and have also been shown, in younger populations, to influence food intake and its psychological antecedents, such as quality perception and satisfaction judgments. The objective of this paper is to study the direct impact of elderly patients' everyday emotions on food intake and their indirect effects mediated by quality perceptions and satisfaction judgments.

METHODS

Thirty patients (20 women, 10 men, 65-92 age range) in a geriatric rehabilitation unit were observed on repeated meal episodes (average of 46 care episodes per patient) where they provided self-reports for emotions (positive emotions, anger, anxiety, and mild depressed feelings), perceived meal quality, and satisfaction. Food intake was measured in terms of energy and protein content.

RESULTS

The impact on food intake was favorable, and both direct and indirect for positive emotions, direct and negative for anxiety, direct and positive for mild depressed feelings, and indirect and negative for anger. Indirect effects were mediated by quality perception judgments but not by satisfaction, which was not significantly related to food intake.

CONCLUSION

Results suggest that, given their impact on food intake, measuring and monitoring patients' everyday emotions may be an important innovative strategy to improve food intake of elderly patients in institutions.

Non-Pharmacological Interventions in Cognitively Impaired and Demented Patients - A Comparison with Cholinesterase Inhibitors

The present paper reviews studies examining the effects of non-pharmacological stimulation, i.e. bright light, physical activity and tactile stimulation (touch), on cognition, affective behaviour, and the sleep-wake rhythm of impaired and demented elderly, both in a qualitative (narrative) and quantitative (meta-analytic) manner. An extensive search through eight bibliographic data bases (PubMed, Web of Science, ERIC, PsychINFO, Psyndex, Cinahl, Biological Abstracts and Rehabdata) was performed up to August 2002. The primary criterion for inclusion in this review was that studies provided sufficient data to calculate effect-sizes. In the qualitative analysis, all three types of stimulation appeared to improve cognitive functioning. Disturbances in behaviour react positively to bright light and tactile stimulation. Bright light was also beneficial to sleep. Tactile stimulation had, moreover, a beneficial influence on the patient-caretaker relationship. A comparison was made with several representative papers published since 1991 on the effects of acetylcholinesterase inhibitors on cognition and behaviour with representative papers on non-pharmacological stimulation interventions. Data indicated that improvements in cognition and affective behaviour by non-pharmacological interventions (d' = 0.32) and by cholinesterase inhibitors (d' = 0.31) were of similar effect-size. Possible mechanisms underlying the non-pharmacological stimulation effects are discussed and suggestions offered for future research.

Physical touch in nursing studies: a literature review

In nursing contexts a distinction is made between two types of touch: physical touch and therapeutic touch. Physical touch may be experienced as therapeutic, but that is not its explicit purpose in the same way as with therapeutic touch. Most of the touch studies reviewed in this article are from the United States of America, Canada and the United Kingdom and thus represent the culture of modern western society. The area covered by these studies is far from coherent, and even the results are to some extent contradictory. It follows that it is difficult to draw any firm conclusions from this review of the concepts, methods and main results of touch studies.

Caregiver distress. Related to disruptive behaviors on special care units versus traditional long-term care units

The link between staff stress and exposure to disruptive behaviors is an important issue in long-term care settings. This study compared the perceptions of two groups of formal caregivers (staff) regarding their distress from the behaviors of residents in their care. Staff on special care units for dementia were less distressed with disruptive behaviors than comparable staff on traditional units, although they reported higher exposure to these behaviors. These results were related to different perceptions of intent to harm and expectations of physical aggression as "part of the job." Implications for nursing include education and support for staff to enhance the quality of life for residents and staff on units where disruptive behaviors occur.

Intimacy--meeting needs and respecting privacy in the care of elderly people: what is a good moral attitude on the part of the nurse/carer?

This article explores notions of intimacy in the caring context. The aspects discussed are: privacy and intimacy; intimacy as emotional and/or physical closeness; intimacy as touch; sexual intimacy and normal ageing; sexual intimacy and patients suffering from dementia; and intimacy as trust. Examples are given and problems are identified, with reflection on the attitude and behaviour of the carer. It is suggested that when trying to make moral decisions in concrete situations it is imperative that the carer is aware of the values upon which his or her own thinking is based. It is argued that the guiding principle should be the moral assumption that the carer's responsibility can never be interpreted as a right to disregard the wishes of the patient. Hence, the key word in daily care is 'respect'.

Assessment and management of eating and feeding difficulties for older people: a NICHE protocol

Adequate nutritional intake is critical to preserving the health of older people. When an elderly person requires assistance with eating, the most social of all activities of daily living, the assessment of nutritional issues becomes multidimensional and interdisciplinary. Management strategies should involve the professional nurse's attention to dietary needs, as well as the social, cultural, and interactive components of mealtime. Additionally, special strategies need to be developed for people with cognitive and physical disabilities.

Use of a content methodology process to enhance feeding abilities threatened by ideational apraxia in people with Alzheimer's-type dementia

Self-feeding behavior is often the first of a chain of self-maintenance skills to deteriorate in people with Alzheimer's-type dementia and is a major determinant of institutionalization. Moreover, nurses working in geriatric settings report the feeding of patients as a most difficult management problem. Of the various features of Alzheimer's-type dementia that can affect a person's ability to feed him- or herself, ideational apraxia can explain the loss of ability to conceptualize, plan, and execute the complex sequence of motor actions involving the use of tools or objects necessary for feeding. In this article, a systematic process is used to review the research literature to develop substantive content for nurses caring for people with feeding problems related to ideational apraxia. Ideational apraxia is a condition in which an individual is unable to plan movement related to an object because he or she has lost the perception of the object's purpose. The specific abilities necessary for feeding that are threatened by ideational apraxia are identified. A tool to assess these abilities is described, and nursing interventions aimed at enhancing or preserving existing abilities, preventing excess disability, or compensating for lost abilities are presented.

Refusal to eat in the elderly

Refusal to eat by the elderly, and subsequent malnutrition, occurs in both institutional and community settings. Causes include physiologic changes associated with aging, mental disorders such as dementia and depression, and medical, social, and environmental factors. Treatment approaches call for management of these causes while considering the roles that medicine, ethics, and culture play in the process.

Improving eating behaviors in dementia using behavioral strategies

The purpose of this experimental pilot study was to determine the short- and long-term efficacy of directed verbal prompts and positive reinforcement on the level of eating independence (LEI) of elderly nursing home patients with dementia. Twenty-four subjects from a dementia unit were randomly selected and randomly assigned to three experimental groups and three control groups. The LEI scale was used to measure eating frequency and task performance at six consecutive meals during pretest and posttests, T2 and T3. During the treatment phase, which consisted of nine consecutive meals, prompts were administered to each experimental group and positive reinforcement was given when a subject completed eating tasks. Short-term effects were assessed on 2 consecutive days following treatment (T2) and long-term effects on 2 consecutive days, 7 days following treatment. Significant differences were found in eating performance but not in frequency. Experimental groups retained treatment at both posttests. The dementia diagnosis should not preclude the possibility that eating skills may be reacquired.

Good nutritional oral intake is associated with equal survival in demented and nondemented very old patients

OBJECTIVE

To evaluate the association of oral food intake with survival in very old demented nursing home patients.

DESIGN

A prospective cohort study.

SETTING

A nursing home in northern Italy.

MEASUREMENTS

Anthropometric and laboratory nutritional indicators and nutrient intake were assessed in 33 demented (age 85.7 +/- 5.7 years) and 25 nondemented (age 84.9 +/- 5.7 years) patients. Mortality data were collected over a 28-month follow-up period. Association of survival with dementia was estimated by Kaplan-Meyer analysis and multivariate Cox proportional hazard models.

RESULTS

Nutrient intake and nutritional status were good compared with data in the literature and were similar in demented and nondemented patients, except for smaller triceps skinfold thickness in the demented. The cumulative annual death rate was 0.23 deaths per subject per year, similar in the demented (0.23) and the nondemented (0.22). Unadjusted survival by Kaplan-Meyer analysis was similar in the two groups, and correction for-age, gender, cognition, triceps skinfold thickness, and number of drugs in a Cox model did not alter the relationship.

CONCLUSIONS

Dementia developing in very old age is not necessarily associated with malnutrition and decreased life expectancy.

Developing an instrument for the observation of touching

This article describes the development of an instrument for the observation of nonnecessary touching and its purposes in interaction between nursing staff and elderly patients in long-term care. The work took place on three wards of a nursing home. The instrument is based on three main concepts: verbal communication, touch as a form of nonverbal communication, and nursing care situation. In its finalized form, the instrument consists of a single sheet of paper with the human body pictured from the front and from the back.

Nutritional intake. Use of touch and verbal cuing

1. Many hospitalized elderly patients have inadequate nutritional intake. 2. Inexpensive, practical means of improving the nutritional status of elderly patients are needed. 3. Touch, verbal cuing, and the combination of touch and verbal cuing may be effective methods for increasing the nutritional intake of hospitalized elderly patients without severe cognitive dysfunction.

Factors influencing the perception of touch by elderly nursing home residents and their health caregivers

The purpose of this study was to examine which factors influence the perceptions of touch by elderly nursing home residents and their health caregivers. A random sample of residents (n = 100) and a convenience sample of health caregivers (n = 100) were selected from two nursing homes. The five variables of interest were as follows: staff status; type of touch; area of the body touched; resident's locus of control; and resident's functional level. Vignettes were developed from combinations of variables which described a touch interaction between a resident and caregiver. To determine the main effects of the five variables of interest, fractional factorial analyses of variance were performed. Resident's locus of control appeared to be the most influential factor affecting residents' and caregivers' perceptions of touch. Touch was experienced as positive when it was appropriate to the situation, did not impose greater intimacy than desired, and did not impart a condescending message. Negative touch situations often involved some procedure used in a manner considered "intimate" or when discrepant with the needs of the individual. A conceptual model of interpersonal touch is described and recommendations for further study are discussed.

Maximizing therapist effectiveness with geriatric hand patients

The "graying of America" is resulting in higher proportions of older persons utilizing the health care system. Current trends indicate that the geriatric population represents a growing portion of the hand therapy patient population. Appreciating the unique needs of the geriatric hand patient and developing an appropriate treatment program require special interventions that may seem unappealing due to the likelihood of prolonged initial treatment time. However, such steps can strongly enhance therapist effectiveness, patient compliance, and ultimate outcome. The purposes of this paper are: (1) to address frustrations that may be encountered in the treatment of some elderly hand patients; (2) to introduce the reader to the phenomenon of age bias; (3) to present a well-accepted and effective assessment tool of memory, orientation, and ability to follow commands as these competencies pertain to hand therapy; (4) to address concepts in the gerontology literature that can be applied clinically as treatment guidelines to boost treatment effectiveness; and, finally, (5) to suggest communication techniques to use with the elderly hand patient. Maximizing therapist effectiveness with geriatric hand patients will serve to reinforce the dignity and value of this unique population.

Self-feeding performance in nursing home residents

In a study of cognitively impaired nursing home residents, excess disability was found in the specific mealtime task of drinking liquids and among those eating a puréed diet. Nursing home staff tended to rely on spoonfeeding, a process in which the resident is a passive recipient of care rather than an active participant in it, as an intervention among residents who were partially able to feed themselves. Feeding techniques other than spoonfeeding--including verbal and nonverbal prompts, and physical guiding--can support residents' participation in feeding even when independence is no longer possible.

Measuring feeding difficulty in patients with dementia: perspectives and problems

The feeding problems of demented elderly people are well documented and the need for research into the assessment of feeding difficulty and intervention by nurses has been raised. The present paper reviews the literature in this area of care and outlines the problems which exist in attempting to investigate the feeding difficulty of demented patients. Demented elderly people display a range of behaviours related to feeding including excessive eating in the early stages of dementia and then difficulty with feeding, refusal to eat and, finally, inability to self-feed at all. The problems with research in this area revolve around the issue of measurement of feeding difficulty. There are problems in deciding what to measure and in how measurements should be made which are clinically meaningful. A possible strategy for investigating the feeding difficulty of demented elderly patients is suggested which includes the design of a tool for measurement and the application of single-case studies. Any tool which is used for measurement should enable researchers, in the first instance, and then clinicians to categorize the feeding difficulty of individual patients. Moreover, such a tool should also be sufficiently sensitive to respond to change in feeding ability. The single-case methodology is considered to be the most ethically and statistically appropriate for research with this particular group of patients.

Agitation and touch in the nursing home

The relationship between manifestations of agitated behaviors and interpersonal distance was examined in 24 nursing home residents with high agitation and severe cognitive impairment. Analysis indicated that agitated residents displayed divergent responses to touch: touch was related to an increase in aggressive behaviors and to a decrease in physically nonaggressive behaviors (e.g., strange movements). The positive relationship between aggressiveness and touching suggests that residents may interpret touching as a violation of their personal space. The finding that residents exhibited fewer strange movements when touched suggests that touching can act as a quieting and comforting form of communication. The implications of these findings for caregivers are discussed.
