An intervention to increase fluid intake in nursing home residents: prompting and preference compliance

Low-intake dehydration prevalence in non-hospitalised older adults: Systematic review and meta-analysis

BACKGROUND & AIMS

Low-intake dehydration amongst older people, caused by insufficient fluid intake, is associated with mortality, multiple long-term health conditions and hospitalisation. The prevalence of low-intake dehydration in older adults, and which groups are most at-risk, is unclear. We conducted a high-quality systematic review and meta-analysis, implementing an innovative methodology, to establish the prevalence of low-intake dehydration in older people (PROSPERO registration: CRD42021241252).

METHOD

We systematically searched Medline (Ovid), Cochrane CENTRAL, Embase (Ovid), CINAHL and Proquest from inception until April 2023 and Nutrition and Food Sciences until March 2021. We included studies that assessed hydration status for non-hospitalised participants aged ≥65 years, by directly-measured serum/plasma osmolality, calculated serum/plasma osmolarity and/or 24-h oral fluid intake. Inclusion, data extraction and risk of bias assessment was carried out independently in duplicate.

RESULTS

From 11,077 titles and abstracts, we included 61 (22,398 participants), including 44 in quality-effects meta-analysis. Meta-analysis suggested that 24% (95% CI: 0.07, 0.46) of older people were dehydrated (assessed using directly-measured osmolality >300 mOsm/kg, the most reliable measure). Subgroup analyses indicated that both long-term care residents (34%, 95% CI: 0.09, 0.61) and community-dwelling older adults (19%, 95% CI: 0.00, 0.48) were highly likely to be dehydrated. Those with more pre-existing illnesses (37%, 95% CI: 0.14, 0.62) had higher low-intake dehydration prevalence than others (15%, 95% CI: 0.00, 0.43), and there was a non-significant suggestion that those with renal impairment (42%, 95% CI: 0.23, 0.61) were more likely to be dehydrated than others (23%, 95% CI: 0.03, 0.47), but there were no clear differences in prevalence by age, sex, functional, cognitive or diabetic status. GRADE quality of evidence was low as to the exact prevalence due to high levels of heterogeneity between studies.

CONCLUSION

Quality-effects meta-analysis estimated that a quarter of non-hospitalised older people were dehydrated. Widely varying prevalence rates in individual studies, from both long-term care and community groups, highlight that dehydration is preventable amongst older people.

IMPLICATIONS

One in every 4 older adults has low-intake dehydration. As dehydration is serious and prevalent, research is needed to better understand drinking behaviour and assess effectiveness of drinking interventions for older people.

Effect of an Audible Alarm on the Fluid Consumption of Older Adults Living in a Nursing Home: A Randomized Controlled Trial

The aim of the current study was to investigate the effect of an audible alarm on fluid consumption among older adults living in a nursing home. This single-blind, randomized controlled, prospective experimental study was performed between July 27, 2017, and February 1, 2018. This study comprised 100 participants (intervention group, n = 50; control group, n = 50). The amount of fluid consumed by older adults in the intervention group in relation to the audible alarm increased significantly compared to the control group, and the deficiency of fluid consumption decreased. It was determined that the wristwatch with audible alarm was effective when used as a reminder to increase fluid consumption among older adults with fluid deficiency. [Journal of Gerontological Nursing, 48(9), 39-46.].

Feasibility and Acceptability Testing of Evidence-Based Hydration Strategies for Residential Care

The current study examined stakeholder perspectives on the perceived effectiveness, feasibility, and acceptability of 20 evidence-based strategies appropriate for residential care via an online survey (N = 162). Most participants worked in long-term care (83%), were direct care providers (62%), worked in food/nutrition roles (55%), and identified as female (94%). Strategies that were rated as effective, feasible, and likely to be used in the future were social drinking events, increased drink options at meals, and pre-thickened drinks. Participants also listed their top strategies for inclusion in a multicomponent intervention. Responses to open-ended questions provided insight on implementation, compliance, and budget constraints. Participant perspectives provide insight into developing a multicomponent intervention. Strategies prioritized for such an intervention include: staff education, social drinking opportunities, drinks trolley, volunteer support, improved beverage availability, hydration reminders, offering preferred beverages, and prompting residents to drink using various cues. [Research in Gerontological Nursing, 15(1), 27-38.].

Interventions to Improve Hydration in Older Adults: A Systematic Review and Meta-Analysis

Dehydration is common in the elderly, especially when hospitalised. This study investigated the impact of interventions to improve hydration in acutely unwell or institutionalised older adults for hydration and hydration linked events (constipation, falls, urinary tract infections) as well as patient satisfaction. Four databases were searched from inception to 13 May 2020 for studies of interventions to improve hydration. Nineteen studies (978 participants) were included and two studies (165 participants) were meta-analysed. Behavioural interventions were associated with a significant improvement in hydration. Environmental, multifaceted and nutritional interventions had mixed success. Meta-analysis indicated that groups receiving interventions to improve hydration consumed 300.93 mL more fluid per day than those in the usual care groups (95% CI: 289.27 mL, 312.59 mL; I² = 0%, p < 0.00001). Overall, there is limited evidence describing interventions to improve hydration in acutely unwell or institutionalised older adults. Behavioural interventions appear promising. High-quality studies using validated rather than subjective methods of assessing hydration are needed to determine effective interventions.

Strategies to prevent dehydration in older people with dementia: a literature review

Dehydration is prevalent in hospitalised older people and residents in care homes, and older people with dementia are particularly at risk. A literature review was conducted to determine the evidence-based interventions used to prevent and manage dehydration in older people with dementia. Three databases were searched for relevant literature: Applied Social Sciences Index and Abstracts, Cumulative Index to Nursing and Allied Health Literature, and MEDLINE, alongside hand-searching. In-depth reading of the 12 studies included in this literature review was undertaken. Five themes were identified in relation to the hydration of older people: physical and social environment; staff communication strategies; access to drinks; drinking vessels; and individual preferences. The evidence suggests that dehydration in older people with dementia is an ongoing concern that needs to be addressed. There is evidence supporting the use of essential nursing interventions to improve hydration, such as coloured cups and verbal prompts, but less is known about the barriers preventing nurses from implementing these evidence-based interventions.

A multidisciplinary consensus on dehydration: definitions, diagnostic methods and clinical implications

Background: Dehydration appears prevalent, costly and associated with adverse outcomes. We sought to generate consensus on such key issues and elucidate need for further scientific enquiry. Materials and methods: A modified Delphi process combined expert opinion and evidence appraisal. Twelve relevant experts addressed dehydration's definition, objective markers and impact on physiology and outcome. Results: Fifteen consensus statements and seven research recommendations were generated. Key findings, evidenced in detail, were that there is no universally accepted definition for dehydration; hydration assessment is complex and requires combining physiological and laboratory variables; "dehydration" and "hypovolaemia" are incorrectly used interchangeably; abnormal hydration status includes relative and/or absolute abnormalities in body water and serum/plasma osmolality (pOsm); raised pOsm usually indicates dehydration; direct measurement of pOsm is the gold standard for determining dehydration; pOsm >300 and ≤280 mOsm/kg classifies a person as hyper or hypo-osmolar; outside extremes, signs of adult dehydration are subtle and unreliable; dehydration is common in hospitals and care homes and associated with poorer outcomes. Discussion: Dehydration poses risk to public health. Dehydration is under-recognized and poorly managed in hospital and community-based care. Further research is required to improve assessment and management of dehydration and the authors have made recommendations to focus academic endeavours. Key messages Dehydration assessment is a major clinical challenge due to a complex, varying pathophysiology, non-specific clinical presentations and the lack of international consensus on definition and diagnosis. Plasma osmolality represents a valuable, objective surrogate marker of hypertonic dehydration which is underutilized in clinical practice. Dehydration is prevalent within the healthcare setting and in the community, and appears associated with increased morbidity and mortality.

An Innovative Approach to Adequate Oral Hydration in an Inpatient Geriatric Psychiatry Unit

Suboptimal hydration status and dehydration are problems that often exacerbate comorbid conditions in geriatric patients. At a Veterans Administration Hospital, it was observed that suboptimal hydration status in Veterans hospitalized in the geriatric psychiatry unit was a contributing factor in the worsening of their psychiatric and medical conditions. A quality improvement project was chartered to improve hydration in this group of patients. Using a three-pronged intervention approach (i.e., providing flavored water, providing larger cups, and increasing the prompting by nurses for patients to drink more), the project was successful. The goal was to increase average daily fluid intake by 125 mL; the result was an increase of 700 mL. This project has been sustained and the interventions have also benefitted non-geriatric psychiatry in-patients. [Journal of Psychosocial Nursing and Mental Health Services, 57(4), 15-20.].

Negative prompts aimed at maintaining eating independence

Background:

Psychological abuse of older people is difficult to recognise; specifically, nursing home residents have been documented to be at higher risk of psychological abuse during daily care, such as during feeding. Healthcare professionals adopt positive and negative verbal prompts to maintain residents’ eating independence; however, negative prompts’ purposes and implications have never been discussed to date.

Research aims:

To critically analyse negative verbal prompts given during mealtimes as forms of abuse of older individuals and violation of ethical principles.

Research design:

This is a secondary analysis of three cases of negative prompts that emerged in a large descriptive study based upon focus group methodology and involving 13 nursing homes and 54 healthcare professionals.

Participants and research context:

This study included 3 out of 13 nursing homes caring for residents with moderate/severe functional dependence in self-feeding mainly due to dementia; in these nursing homes, we conducted three focus groups and 13 healthcare professionals participated.

Ethical considerations:

This study was conducted in accordance with the Human Subject Research Ethics Committee guidelines after being approved by the Review Board of the Trust.

Findings:

With the intent of maintaining self-feeding independence, negative verbal prompts have been reported as being used by nursing home teams. By critically analysing these negative prompts, it turned out they could trigger intimidation, depression and anxiety and thus could be considered as forms of abuse; moreover, negative prompts can threaten the ethical principles of (1) autonomy using a paternalist approach, (2) beneficence and non-maleficence as with the intent to act in the best interests of residents (to maintain self-feeding independence) they are harmed in their dignity and (3) justice, given that residents who received negative prompts are treated differently from those who received positive prompts.

Discussion:

Eating should be a pleasant experience with a positive impact on physiological, psychological and social well-being. However, negative prompting can lead to abuse and violation of basic ethical principles, destroying the healthcare professional resident and relative relationships strongly dependent on trust.

Conclusion:

Negative verbal prompting must be avoided.

Drinking vessel preferences in older nursing home residents: optimal design and potential for increasing fluid intake

BACKGROUND:

residents in nursing and residential care homes are at risk of dehydration due to both resident and institutional factors. Previous studies have focused on improving fluid intakes by concentrating on types of fluids offered and assisting residents to drink.

AIM:

to determine resident opinion of the optimal features of drinking vessels and evaluate the impact of improving vessel design on fluid consumption.

METHODS:

residents from two units (25-bed and 21-bed) in one nursing home evaluated a range of drinking vessels. Vessels with preferred features were introduced on a 25-bed unit. The effect was tested by observing residents' fluid consumption during breakfast on three consecutive days and comparing with baseline intakes.

FINDINGS:

vessels that received the highest ratings were lightweight, had large handles and held 200-300 ml of fluid. Following the introduction of the new drinking vessels, mean fluid intakes at breakfast increased from 139 ml (±84 ml) to 205 ml (±12 ml, n=65), p=0.003.

CONCLUSION:

some drinking vessels used in nursing homes may be difficult for residents to handle. Making improvements to the design of drinking vessels has the potential to increase fluid intakes without increasing staff workload.

Hydration practices in residential and nursing care homes for older people

AIM

To scope and explore hydration practices in care homes.

BACKGROUND

Older residents do not regularly consume adequate fluids to support health. Achieving this is difficult with residents who have coexisting health, sensory and functional problems, as well as challenging hydration habits.

DESIGN

This project used a sequential exploratory mixed method design to scope and explore existing hydration practices.

METHODS

Data were collected via two stages. First was a survey of hydration practices. Twenty-nine responses were received from 81 care homes (response rate: 35.8%). Second was the exploration of practitioners' experiences and perceptions of hydration practice via semi-structured interviews (54 staff: 43 interviews). Descriptive statistics summarised the survey findings. Open coding and thematic analysis were applied to the qualitative data, and details of the methods are reported in adherence to COREQ criteria.

RESULTS

It is important to provide hydration support in addition to regularly offering drinks to residents. Hydration practices include the following: use of social interaction to encourage drinking; verbal and nonverbal prompts to drink; giving fluids with routine practices and social activities; providing drinks-related activity, use of aids and equipment to support drinking; and creating a drink-friendly environment. Practices are implemented in care homes; however, no one care home implements all these hydration strategies at any one time.

CONCLUSIONS

Older care home residents need support and encouragement to drink adequate fluids which can be difficult to achieve with residents who have complex needs and challenging drinking habits. In addition to the routine offer of drinks, hydration support should be used to facilitate residents to drink sufficient amounts of fluid.

RELEVANCE TO CLINICAL PRACTICE

Staff working in care homes have an important role in assessing the hydration needs of residents and using multiple hydration practices to support residents to achieve their hydration requirements.

Prevalence and Risk Factors Associated With Low Fluid Intake in Institutionalized Older Residents

OBJECTIVE

The aim of this study was to determine the prevalence of low fluid intake in institutionalized older residents and the associated factors.

DESIGN

This was a cross-sectional study.

SETTING AND PARTICIPANTS

The study was carried out at a nursing home with a capacity for 156 residents, all of whom were older than 65 years.

MEASURES

Data were collected on the fluids consumed by each resident over a period of 1 week. Information relating to sociodemographic variables and to residents' health, nutrition, and hydration status was also collected.

RESULTS

Of 53 residents, 34% ingested less than 1500 mL/d. The factors with the greatest correlation associated with low fluid intake were cognitive and functional impairment, the risk of suffering pressure ulcers, being undernourished, a texture-modified diet, dysphagia, impaired swallowing safety, and BUN:creatinine ratio.

CONCLUSIONS/IMPLICATIONS

The results obtained highlight the scale of low fluid intake in nursing homes and also aid to identify and understand the factors associated with this problem. The findings could help us to develop specific strategies to promote the intake of liquids and thereby reduce the incidence of dehydration in nursing homes.

Best intentions or best practice? A case study of the nutritional needs and outcomes of a person with dementia living in a residential aged care home

AIMS

To evaluate the nutritional status and needs of a person with dementia living in an aged care home, including identification of barriers to, and effective strategies for, the provision of person-centred care.

BACKGROUND

Nutrition and hydration care are integral to quality of life for adults with dementia, but there is little research on whether staff knowledge around effective care strategies for residents is translated into optimal care.

DESIGN

Focused ethnographic single-case design.

METHODS

The perspectives of the resident, her prime family member, and six care staff were triangulated through interviews, observation, document audit, and medical file review to investigate the resident's nutrition and hydration status and needs (October 2014-April 2015).

RESULTS

During 3 years in care, this resident had lost weight steadily. Staff appeared attentive but did not maintain a systematic record of body mass index. At meals, staff encouraged eating but used ineffective strategies. Food was not served in ways that facilitated active participation. Eating and drinking were structured as tasks to be completed rather than activities to be enjoyed.

CONCLUSION

This instrumental case study identified a task-oriented, rather than person-centred, approach to nutrition and hydration care, adversely affecting the resident's nutritional health and capability to participate actively.

Improving hydration of care home residents by increasing choice and opportunity to drink: A quality improvement study

BACKGROUND & AIMS

Dehydration is recognised as an important problem among care home residents and can be associated with severe consequences. Insufficient provision of fluids to meet resident preferences and lack of assistance to drink have been identified as key factors driving under-hydration of care home residents. Using targeted interventions, this study aimed to optimise hydration care for frail older people in a care home setting.

METHODS

The study used quality improvement methods to develop and test interventions to extend drinking opportunities and choice in two care homes. Changes were made and evaluated using Plan-Do-Study-Act (PDSA) cycles. Data were captured on the amount of fluids served and consumed, and staff and resident feedback. The long-term impact of the interventions was assessed by measuring daily laxative and antibiotic consumption, weekly incidence of adverse health events, and average fluid intake of a random sample of six residents captured monthly.

RESULTS

The interventions were associated with an increase in the amount and range of fluids consumed, in one home mean fluid intakes exceeded 1500 ml for three consecutive months. Laxative use decreased significantly in both homes. A number of practical and organisational barriers affected the sustainability of interventions.

CONCLUSIONS

Interventions to optimise the hydration of care home residents can be effective. Plan-Do-Study-Act cycles provide an effective methodology to implement new interventions into existing practice in care homes. Sustainable change requires strong leadership, organisational support and teamwork.

A qualitative study exploring staff attitudes to maintaining hydration in neurosurgery patients

AIMS

To explore staff perceptions of the processes and influences on maintaining patients' hydration on a busy neurosurgery ward.

BACKGROUND

Dehydration continues to be a major concern in the NHS where its avoidance is hindered by complications arising from clinical conditions, poor assessment and documentation of hydration and a lack of staff time to monitor fluid intake. Recent work has explored patient perceptions of hydration care but there has been little conducted recently that has explored those of staff.

METHODS

Semi-structured interviews were conducted with staff working on a neurosurgery ward during 2016. We used open-ended questions to elicit experiences of hydration care and explore factors that influenced the maintenance of hydration in patients.

RESULTS

We found that staff were aware of the importance of hydration and saw it as a central aspect of the care they provided. A range of staff are involved in the assessment of patients' hydration requirements and their ability to meet them. Similarly all staff were expected to provide oral fluids for patients able to drink independently. Competing priorities inhibited the time staff could spend providing hydration care which had an impact on the timely and accurate completion of fluid balance charts and meant that relatives were relied on to support patients requiring assistance in drinking.

Methods of Assessment of Hydration Status and their Usefulness in Detecting Dehydration in the Elderly

Assessment of hydration status is complex and difficult to achieve. Few assessment methods have been validated to accurately measure the fluid compartments in the body, but they have little application in practice. Different techniques have been developed to determine hydration status for the use in clinical settings, but their diagnostic accuracy remains questionable. Since many experts argue that there is no 'gold-standard' technique and one can never be achieved, this paper describes both, the benefits and limitations of the available methods and their usability in assessing hydration status of the elderly.

Elevated Serum Osmolality and Total Water Deficit Indicate Impaired Hydration Status in Residents of Long-Term Care Facilities Regardless of Low or High Body Mass Index

BACKGROUND

Dehydration is typically associated with underweight and malnutrition in long-term care (LTC) settings. Evidence is lacking regarding the influence of the rising prevalence of overweight and obesity on risk factors, prevalence, and presentation of dehydration.

OBJECTIVE

The aim of this study was to objectively assess hydration status and the adequacy of total water intake, and determine relationships between hydration status, total water intake, and body mass index (BMI) in LTC residents.

DESIGN

A cross-sectional analysis of baseline data was performed.

PARTICIPANTS AND SETTING

Baseline data from 247 subjects recruited from eight community-based LTC facilities participating in two randomized trials comparing nutrient and cost-efficacy of between-meal snacks vs oral nutrition supplements (ONS).

MAIN OUTCOMES

Hydration status was assessed by serum osmolality concentration and total water intakes were quantified by weighed food, beverage, water, and ONS intake.

STATISTICAL ANALYSES

Simple and multiple linear regression methods were applied.

RESULTS

Forty-nine (38.3%) subjects were dehydrated (>300 mOsm/kg) and another 39 (30.5%) had impending dehydration (295 to 300 mOsm/kg). The variance in serum osmolality was significantly accounted for by blood urea nitrogen level, mental status score, and having diabetes (R(2)=0.46; P<0.001). Total water intake averaged 1,147.2±433.1 mL/day. Thus, 96% to 100% of subjects did not meet estimated requirements, with a deficit range of 700 to 1,800 mL/day. The variance in total water intake was significantly accounted for by type of liquid beverages (thin vs thick), type of ONS, total energy intake, total activities of daily living dependence, sex, and BMI (R(2)=0.56; P<0.001).

CONCLUSIONS

Dehydration and inadequate total water intake is prevalent in LTC residents across all BMI categories. Type of liquid beverages, type of ONS, and type of between-meal snacks are factors that could be targeted for nutrition interventions designed to prevent or reverse dehydration.

Clinical assessments and care interventions to promote oral hydration amongst older patients: a narrative systematic review

BACKGROUND

Older patients in hospital may be unable to maintain hydration by drinking, leading to intravenous fluid replacement, complications and a longer length of stay. We undertook a systematic review to describe clinical assessment tools which identify patients at risk of insufficient oral fluid intake and the impact of simple interventions to promote drinking, in hospital and care home settings.

METHOD

MEDLINE, CINAHL, and EMBASE databases and two internet search engines (Google and Google Scholar) were examined. Articles were included when the main focus was use of a hydration/dehydration risk assessment in an adult population with/without a care intervention to promote oral hydration in hospitals or care homes. Reviews which used findings to develop new assessments were also included. Single case reports, laboratory results only, single technology assessments or non-oral fluid replacement in patients who were already dehydrated were excluded. Interventions where nutritional intake was the primary focus with a hydration component were also excluded. Identified articles were screened for relevance and quality before a narrative synthesis. No statistical analysis was planned.

RESULTS

From 3973 citations, 23 articles were included. Rather than prevention of poor oral intake, most focused upon identification of patients already in negative fluid balance using information from the history, patient inspection and urinalysis. Nine formal hydration assessments were identified, five of which had an accompanying intervention/ care protocol, and there were no RCT or large observational studies. Interventions to provide extra opportunities to drink such as prompts, preference elicitation and routine beverage carts appeared to support hydration maintenance, further research is required. Despite a lack of knowledge of fluid requirements and dehydration risk factors amongst staff, there was no strong evidence that increasing awareness alone would be beneficial for patients.

CONCLUSION

Despite descriptions of features associated with dehydration, there is insufficient evidence to recommend a specific clinical assessment which could identify older persons at risk of poor oral fluid intake; however there is evidence to support simple care interventions which promote drinking particularly for individuals with cognitive impairment.

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).

Effectiveness of interventions to directly support food and drink intake in people with dementia: systematic review and meta-analysis

BACKGROUND

Eating and drinking difficulties are recognised sources of ill health in people with dementia. In the EDWINA (Eating and Drinking Well IN dementiA) systematic review we aimed to assess effectiveness of interventions to directly improve, maintain or facilitate oral food and drink intake, nutrition and hydration status, in people with cognitive impairment or dementia (across all settings, levels of care and support, types and degrees of dementia). Interventions included oral nutrition supplementation, food modification, dysphagia management, eating assistance and supporting the social element of eating and drinking.

METHODS

We comprehensively searched 13 databases for relevant intervention studies. 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, carrying out random effects meta-analysis and narrative synthesis.

RESULTS

Forty-three controlled interventions were included, disappointingly none were judged at low risk of bias. Oral nutritional supplementation studies suggested small positive short term but unclear long term effects on nutritional status. Food modification or dysphagia management studies were smaller and of low quality, providing little evidence of an improved nutritional status. Eating assistance studies provided inconsistent evidence, but studies with a strong social element around eating/drinking, although small and of low quality provided consistent suggestion of improvements in aspects of quality of life. There were few data to address stakeholders' questions.

CONCLUSIONS

We found no definitive evidence on effectiveness, or lack of effectiveness, of specific interventions but studies were small and short term. People with cognitive impairment and their carers have to tackle eating problems despite this lack of evidence, so promising interventions are listed. The need remains for high quality trials tailored for people with cognitive impairment assessing robust outcomes.

Clinical symptoms, signs and tests for identification of impending and current water-loss dehydration in older people

BACKGROUND

There is evidence that water-loss dehydration is common in older people and associated with many causes of morbidity and mortality. However, it is unclear what clinical symptoms, signs and tests may be used to identify early dehydration in older people, so that support can be mobilised to improve hydration before health and well-being are compromised.

OBJECTIVES

To determine the diagnostic accuracy of state (one time), minimally invasive clinical symptoms, signs and tests to be used as screening tests for detecting water-loss dehydration in older people by systematically reviewing studies that have measured a reference standard and at least one index test in people aged 65 years and over. Water-loss dehydration was defined primarily as including everyone with either impending or current water-loss dehydration (including all those with serum osmolality ≥ 295 mOsm/kg as being dehydrated).

SEARCH METHODS

Structured search strategies were developed for MEDLINE (OvidSP), EMBASE (OvidSP), CINAHL, LILACS, DARE and HTA databases (The Cochrane Library), and the International Clinical Trials Registry Platform (ICTRP). Reference lists of included studies and identified relevant reviews were checked. Authors of included studies were contacted for details of further studies.

SELECTION CRITERIA

Titles and abstracts were scanned and all potentially relevant studies obtained in full text. Inclusion of full text studies was assessed independently in duplicate, and disagreements resolved by a third author. We wrote to authors of all studies that appeared to have collected data on at least one reference standard and at least one index test, and in at least 10 people aged ≥ 65 years, even where no comparative analysis has been published, requesting original dataset so we could create 2 x 2 tables.

DATA COLLECTION AND ANALYSIS

Diagnostic accuracy of each test was assessed against the best available reference standard for water-loss dehydration (serum or plasma osmolality cut-off ≥ 295 mOsm/kg, serum osmolarity or weight change) within each study. For each index test study data were presented in forest plots of sensitivity and specificity. The primary target condition was water-loss dehydration (including either impending or current water-loss dehydration). Secondary target conditions were intended as current (> 300 mOsm/kg) and impending (295 to 300 mOsm/kg) water-loss dehydration, but restricted to current dehydration in the final review.We conducted bivariate random-effects meta-analyses (Stata/IC, StataCorp) for index tests where there were at least four studies and study datasets could be pooled to construct sensitivity and specificity summary estimates. We assigned the same approach for index tests with continuous outcome data for each of three pre-specified cut-off points investigated.Pre-set minimum sensitivity of a useful test was 60%, minimum specificity 75%. As pre-specifying three cut-offs for each continuous test may have led to missing a cut-off with useful sensitivity and specificity, we conducted post-hoc exploratory analyses to create receiver operating characteristic (ROC) curves where there appeared some possibility of a useful cut-off missed by the original three. These analyses enabled assessment of which tests may be worth assessing in further research. A further exploratory analysis assessed the value of combining the best two index tests where each had some individual predictive ability.

MAIN RESULTS

There were few published studies of the diagnostic accuracy of state (one time), minimally invasive clinical symptoms, signs or tests to be used as screening tests for detecting water-loss dehydration in older people. Therefore, to complete this review we sought, analysed and included raw datasets that included a reference standard and an index test in people aged ≥ 65 years.We included three studies with published diagnostic accuracy data and a further 21 studies provided datasets that we analysed. We assessed 67 tests (at three cut-offs for each continuous outcome) for diagnostic accuracy of water-loss dehydration (primary target condition) and of current dehydration (secondary target condition).Only three tests showed any ability to diagnose water-loss dehydration (including both impending and current water-loss dehydration) as stand-alone tests: expressing fatigue (sensitivity 0.71 (95% CI 0.29 to 0.96), specificity 0.75 (95% CI 0.63 to 0.85), in one study with 71 participants, but two additional studies had lower sensitivity); missing drinks between meals (sensitivity 1.00 (95% CI 0.59 to 1.00), specificity 0.77 (95% CI 0.64 to 0.86), in one study with 71 participants) and BIA resistance at 50 kHz (sensitivities 1.00 (95% CI 0.48 to 1.00) and 0.71 (95% CI 0.44 to 0.90) and specificities of 1.00 (95% CI 0.69 to 1.00) and 0.80 (95% CI 0.28 to 0.99) in 15 and 22 people respectively for two studies, but with sensitivities of 0.54 (95% CI 0.25 to 0.81) and 0.69 (95% CI 0.56 to 0.79) and specificities of 0.50 (95% CI 0.16 to 0.84) and 0.19 (95% CI 0.17 to 0.21) in 21 and 1947 people respectively in two other studies). In post-hoc ROC plots drinks intake, urine osmolality and axillial moisture also showed limited diagnostic accuracy. No test was consistently useful in more than one study.Combining two tests so that an individual both missed some drinks between meals and expressed fatigue was sensitive at 0.71 (95% CI 0.29 to 0.96) and specific at 0.92 (95% CI 0.83 to 0.97).There was sufficient evidence to suggest that several stand-alone tests often used to assess dehydration in older people (including fluid intake, urine specific gravity, urine colour, urine volume, heart rate, dry mouth, feeling thirsty and BIA assessment of intracellular water or extracellular water) are not useful, and should not be relied on individually as ways of assessing presence or absence of dehydration in older people.No tests were found consistently useful in diagnosing current water-loss dehydration.

AUTHORS' CONCLUSIONS

There is limited evidence of the diagnostic utility of any individual clinical symptom, sign or test or combination of tests to indicate water-loss dehydration in older people. Individual tests should not be used in this population to indicate dehydration; they miss a high proportion of people with dehydration, and wrongly label those who are adequately hydrated.Promising tests identified by this review need to be further assessed, as do new methods in development. Combining several tests may improve diagnostic accuracy.

Increasing fluid intake and reducing dehydration risk in older people living in long-term care: a systematic review

OBJECTIVE

To assess the efficacy of interventions and environmental factors on increasing fluid intake or reducing dehydration risk in older people living in long-term care facilities.

DESIGN

Systematic review of intervention and observational studies.

DATA SOURCES

Thirteen electronic databases were searched from inception until September 2013 in all languages. References of included papers and reviews were checked.

ELIGIBILITY CRITERIA

Intervention and observational studies investigating modifiable factors to increase fluid intake and/or reduce dehydration risk in older people (≥65 years) living in long-term care facilities who could drink orally.

REVIEW METHODS

Two reviewers independently screened, selected, abstracted data, and assessed risk of bias from included studies; narrative synthesis was performed.

RESULTS

A total of 4328 titles and abstracts were identified, 325 full-text articles were obtained and 23 were included in the review. Nineteen intervention and 4 observational studies from 7 countries investigated factors at the resident, institutional, or policy level. Overall, the studies were at high risk of bias due to selection and attrition bias and lack of valid outcome measures of fluid intake and dehydration assessment. Reported findings from 6 of the 9 intervention studies investigating the effect of multicomponent strategies on fluid intake or dehydration described a positive effect. Components included greater choice and availability of beverages, increased staff awareness, and increased staff assistance with drinking and toileting. Implementation of the US Resident Assessment Instrument reduced dehydration prevalence from 3% to 1%, P = .01. Two smaller studies reported positive effects: one on fluid intake in 9 men with Alzheimer disease using high-contrast red cups, the other involved supplementing 13 mildly dehydrated residents with oral hydration solution over 5 days to reduce dehydration. Modifications to the dining environment, advice to residents, presentation of beverages, and mode of delivery (straw vs beaker; prethickened drinks vs those thickened at the bedside) were inconclusive. Two large observational studies with good internal validity investigated effects of ownership; in Canada, for-profit ownership was associated with increased hospital admissions for dehydration; no difference was seen in dehydration prevalence between US for-profit and not-for-profit homes, although chain facilities were associated with lower odds of dehydration. This US study did not suggest any effect of staffing levels on dehydration prevalence.

CONCLUSIONS

A wide range of interventions and exposures were identified, but the efficacy of many strategies remains unproven due to the high risk of bias present in many studies. Reducing dehydration prevalence in long-term care facilities is likely to require multiple strategies involving policymakers, management, and care staff, but these require further investigation using more robust study methodologies. The review protocol was registered with the International Prospective Register of Systematic Reviews (http://www.crd.york.ac.uk/PROSPERO/display_record.asp?ID=CRD42012003100).

Interventions for enhancing medication adherence

BACKGROUND

People who are prescribed self administered medications typically take only about half their prescribed doses. Efforts to assist patients with adherence to medications might improve the benefits of prescribed medications.

OBJECTIVES

The primary objective of this review is to assess the effects of interventions intended to enhance patient adherence to prescribed medications for medical conditions, on both medication adherence and clinical outcomes.

SEARCH METHODS

We updated searches of The Cochrane Library, including CENTRAL (via http://onlinelibrary.wiley.com/cochranelibrary/search/), MEDLINE, EMBASE, PsycINFO (all via Ovid), CINAHL (via EBSCO), and Sociological Abstracts (via ProQuest) on 11 January 2013 with no language restriction. We also reviewed bibliographies in articles on patient adherence, and contacted authors of relevant original and review articles.

SELECTION CRITERIA

We included unconfounded RCTs of interventions to improve adherence with prescribed medications, measuring both medication adherence and clinical outcome, with at least 80% follow-up of each group studied and, for long-term treatments, at least six months follow-up for studies with positive findings at earlier time points.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted all data and a third author resolved disagreements. The studies differed widely according to medical condition, patient population, intervention, measures of adherence, and clinical outcomes. Pooling results according to one of these characteristics still leaves highly heterogeneous groups, and we could not justify meta-analysis. Instead, we conducted a qualitative analysis with a focus on the RCTs with the lowest risk of bias for study design and the primary clinical outcome.

MAIN RESULTS

The present update included 109 new RCTs published since the previous update in January 2007, bringing the total number of RCTs to 182; we found five RCTs from the previous update to be ineligible and excluded them. Studies were heterogeneous for patients, medical problems, treatment regimens, adherence interventions, and adherence and clinical outcome measurements, and most had high risk of bias. The main changes in comparison with the previous update include that we now: 1) report a lack of convincing evidence also specifically among the studies with the lowest risk of bias; 2) do not try to classify studies according to intervention type any more, due to the large heterogeneity; 3) make our database available for collaboration on sub-analyses, in acknowledgement of the need to make collective advancement in this difficult field of research. Of all 182 RCTs, 17 had the lowest risk of bias for study design features and their primary clinical outcome, 11 from the present update and six from the previous update. The RCTs at lowest risk of bias generally involved complex interventions with multiple components, trying to overcome barriers to adherence by means of tailored ongoing support from allied health professionals such as pharmacists, who often delivered intense education, counseling (including motivational interviewing or cognitive behavioral therapy by professionals) or daily treatment support (or both), and sometimes additional support from family or peers. Only five of these RCTs reported improvements in both adherence and clinical outcomes, and no common intervention characteristics were apparent. Even the most effective interventions did not lead to large improvements in adherence or clinical outcomes.

AUTHORS' CONCLUSIONS

Across the body of evidence, effects were inconsistent from study to study, and only a minority of lowest risk of bias RCTs improved both adherence and clinical outcomes. Current methods of improving medication adherence for chronic health problems are mostly complex and not very effective, so that the full benefits of treatment cannot be realized. The research in this field needs advances, including improved design of feasible long-term interventions, objective adherence measures, and sufficient study power to detect improvements in patient-important clinical outcomes. By making our comprehensive database available for sharing we hope to contribute to achieving these advances.

Focus on Feeding! Evaluation of a framework for maximizing mealtime in aged care facilities

Unintentional weight loss is a health risk for residents of aged care facilities, a concern for families and places demands on nursing staff. An existing weight loss framework to assess and manage residents' weight developed by a multidisciplinary team was implemented and evaluated with nurses and residents in aged care facilities within an area health service of Sydney, Australia. Thematic analysis generated seven binary concepts relating to relational, procedural, behavioural, physical, psychological, environmental and temporal aspects of feeding assistance provided by nurses to residents. Theoretical sampling was applied to the literature confirming those concepts which were organized as a model of feeding assistance labelled the Focus on Feeding! Decision Model. Nurses can play a pivotal role in the assessment of feeding difficulty and implementation of innovative mealtime programs. The Model aims to promote nurses' critical thinking and decision-making to improve nutritional intake of residents and avoid preventable weight loss.

Water-loss dehydration and aging

This review defines water-loss and salt-loss dehydration. For older people serum osmolality appears the most appropriate gold standard for diagnosis of water-loss dehydration, but clear signs of early dehydration have not been developed. In older adults, lower muscle mass, reduced kidney function, physical and cognitive disabilities, blunted thirst, and polypharmacy all increase dehydration risk. Cross-sectional studies suggest a water-loss dehydration prevalence of 20-30% in this population. Water-loss dehydration is associated with higher mortality, morbidity and disability in older people, but evidence is still needed that this relationship is causal. There are a variety of ways we may be able to help older people reduce their risk of dehydration by recognising that they are not drinking enough, and being helped to drink more. Strategies to increase fluid intake in residential care homes include identifying and overcoming individual and institutional barriers to drinking, such as being worried about not reaching the toilet in time, physical inability to make or to reach drinks, and reduced social drinking and drinking pleasure. Research needs are discussed, some of which will be addressed by the FP7-funded NU-AGE (New dietary strategies addressing the specific needs of elderly population for a healthy ageing in Europe) trial.

Consuming two additional serves of dairy food a day significantly improves energy and nutrient intakes in ambulatory aged care residents: a feasibility study

OBJECTIVES

[corrected] Low-level aged-care residents are at risk of malnutrition. Oral supplements and fortified foods used to treat malnutrition in the elderly require special preparation and administration by staff. Therefore we aimed to determine if increasing dairy food intake in residents by two serves per day would improve energy and nutrient intakes and prevent malnutrition in residents.

DESIGN

Prospective intervention study.

SETTING

2 intervention and 2 control low-level aged-care facilities in Melbourne, Australia.

PARTICIPANTS

130 residents (n = 68 intervention, 78% female, mean age 86.5 years).

INTERVENTION

This feasibility study was a 4-week intervention where menus were modified to include at least two additional serves of dairy food/day. Control facilities consumed from their regular menus.

MEASUREMENTS

Mean macro- and micro-nutrient intakes before and after intervention and over the same time period in controls were recorded using observed intake (food served minus waste) and changes over time determined using paired t-tests. Comparison in proportion of residents meeting nutritional requirements was determined using Chi-square distribution test.

RESULTS

Following intervention, daily increases in mean energy intake (900kJ, P<0.001), protein intake (+25g, P<0.0001), proportion of energy from protein (+4%, P<0.0001) and proportion of estimated energy requirements (EER) (+18%, P<0.0001) were observed, while proportion of energy from fat decreased (-3%, P<0.0001). In controls mean energy intake remained below the EER, and protein intake remained unchanged. Increases in mean daily micronutrient intakes were observed for numerous nutrients including calcium (+679mg, P<0.0001), vitamin D (+1.4μg, P<0.0001), phosphorus (+550mg, P<0.0001), and zinc (+2.8mg, P<0.0001), which remained unchanged in control residents. Calcium and zinc intakes achieved recommended intake levels on the higher dairy diet, but were below recommended levels in controls. Mean sodium intakes remained unchanged. During intervention a greater proportion of residents achieved the EER for energy and the RDI for protein and calcium compared to controls.

CONCLUSION

Two additional serves of dairy food can significantly improve nutrient intake in aged-care residents and its ease of provision makes it a viable option to potentially prevent malnutrition.

Meeting the nutritional needs of elderly residents in aged-care: are we doing enough?

OBJECTIVES

[corrected] Institutionalized elderly are at high risk of malnutrition, including those residing in low-level aged-care and able to self-feed. We used comprehensive dietary intake assessments to determine the nutritional adequacy of food served to residents and if food waste contributed to insufficient nutrient intakes.

DESIGN

Cross sectional.

SETTING

18 low-level aged care facilities.

PARTICIPANTS

199 residents (mean age 86.7 yrs, 76% females).

MEASUREMENTS

Dietary data using 3-6 day weighed food records. Foods were categorized into main food groups (grains, fruit, vegetables, meats, dairy and 'extra') and quantified based on recommended serving sizes. Chi squared test was used to determine sex differences in proportion of residents below recommended intake levels.

RESULTS

Residents were provided with sufficient serves of fruit (>2) and meats (>1), but not dairy (<3), vegetables (<5) and grain foods (women only, <4), and excess serves of 'extra' foods (>2). Mean dietary intakes did not meet recommendations for calcium, zinc, magnesium, potassium, folate and dietary fibre with many residents not meeting energy and protein requirements. Sodium intake was up to 3 times higher than recommended, and sugars consumed in excess. Food waste was 0-15% and resulted in men not consuming recommended serves of grain foods. 'Extra' foods contributed substantially to energy intake but provided few of the required nutrients.

CONCLUSION

Substituting some 'extra' foods for serves of dairy, vegetables and wholegrain foods would improve the nutritional quality of foods, without altering food volume, so is feasible to improve nutritional status in elderly aged-care residents.

A systematic mapping review of randomized controlled trials (RCTs) in care homes

Background

A thorough understanding of the literature generated from research in care homes is required to support evidence-based commissioning and delivery of healthcare. So far this research has not been compiled or described. We set out to describe the extent of the evidence base derived from randomized controlled trials conducted in care homes.

Methods

A systematic mapping review was conducted of the randomized controlled trials (RCTs) conducted in care homes. Medline was searched for “Nursing Home”, “Residential Facilities” and “Homes for the Aged”; CINAHL for “nursing homes”, “residential facilities” and “skilled nursing facilities”; AMED for “Nursing homes”, “Long term care”, “Residential facilities” and “Randomized controlled trial”; and BNI for “Nursing Homes”, “Residential Care” and “Long-term care”. Articles were classified against a keywording strategy describing: year and country of publication; randomization, stratification and blinding methodology; target of intervention; intervention and control treatments; number of subjects and/or clusters; outcome measures; and results.

Results

3226 abstracts were identified and 291 articles reviewed in full. Most were recent (median age 6 years) and from the United States. A wide range of targets and interventions were identified. Studies were mostly functional (44 behaviour, 20 prescribing and 20 malnutrition studies) rather than disease-based. Over a quarter focussed on mental health.

Conclusions

This study is the first to collate data from all RCTs conducted in care homes and represents an important resource for those providing and commissioning healthcare for this sector. The evidence-base is rapidly developing. Several areas - influenza, falls, mobility, fractures, osteoporosis – are appropriate for systematic review. For other topics, researchers need to focus on outcome measures that can be compared and collated.

An exploration of the hydration care of older people: a qualitative study

BACKGROUND

Older adults are more susceptible to water imbalance and ensuring they drink sufficiently is a complex and challenging issue for nurses. The factors that promote adequate hydration and the barriers which prevent older people from drinking are not well understood.

OBJECTIVE

This study aimed to understand the complexity of issues associated with the hydration and hydration care of older people.

DESIGN

A qualitative study using multiple methods.

SETTINGS

Two healthcare sites providing care for older people in the South West of England: a hospital ward in a major hospital and a care home providing personal and nursing care.

PARTICIPANTS

Twenty-one older people aged 68-96 years, were recruited to the study from the hospital ward and care home. The inclusion criteria for older people to participate were men or women aged 65 years and over and the exclusion criteria were being unable to provide informed consent, or being too ill or distressed to take part in the study. The staff participants of nurses and health care assistants totalled 21. The inclusion criterion for staff was any nurse or health care assistant providing hydration care. Seven friends or relatives participated by making anonymous comments via a suggestion box available to all friends and relatives.

METHODS

Data were collected via interviews with older people, focus group discussions involving staff, suggestion box comments made by friends and relatives and twelve hours observation of hydration practice. The data were analysed using thematic analysis.

RESULTS

Health professionals successfully employed several strategies to promote drinking including verbal prompting, offering choice, placing drinks in older people's hands and assisting with drinking. Older people revealed their experience of drinking was diminished by a variety of factors including a limited aesthetic experience and a focus on fluid consumption rather than on drinking as a pleasurable and social experience.

CONCLUSION

The rich and varied dimensions usually associated with drinking were lacking and the role of drinking beverages to promote social interaction was underplayed in both settings. Hydration practice which supports the individual needs of older people is complex and goes beyond simply ensuring the consumption of adequate fluids.

A theoretically based Behavioral Nutrition Intervention for Community Elders at high risk: the B-NICE randomized controlled clinical trial

We conducted a study designed to evaluate the efficacy and feasibility of a multilevel self-management intervention to improve nutritional intake in a group of older adults receiving Medicare home health services who were at especially high risk for experiencing undernutrition. The Behavioral Nutrition Intervention for Community Elders (B-NICE) trial used a prospective randomized controlled design to determine whether individually tailored counseling focused on social and behavioral aspects of eating resulted in increased caloric intake and improved nutrition-related health outcomes in a high-risk population of older adults. The study was guided by the theoretical approaches of the Ecological Model and Social Cognitive Theory. The development and implementation of the B-NICE protocol, including the theoretical framework, methodology, specific elements of the behavioral intervention, and assurances of the treatment fidelity, as well as the health policy implications of the trial results, are presented in this article.

Randomized multilevel intervention to improve outcomes of residents in nursing homes in need of improvement

OBJECTIVES

A comprehensive multilevel intervention was tested to build organizational capacity to create and sustain improvement in quality of care and subsequently improve resident outcomes in nursing homes in need of improvement.

DESIGN/SETTING/PARTICIPANTS

Intervention facilities (N = 29) received a 2-year multilevel intervention with monthly on-site consultation from expert nurses with graduate education in gerontological nursing. Attention control facilities (N = 29) that also needed to improve resident outcomes received monthly information about aging and physical assessment of elders.

INTERVENTION

The authors conducted a randomized clinical trial of nursing homes in need of improving resident outcomes of bladder and bowel incontinence, weight loss, pressure ulcers, and decline in activities of daily living. It was hypothesized that following the intervention, experimental facilities would have higher quality of care, better resident outcomes, more organizational attributes of improved working conditions than control facilities, higher staff retention, similar staffing and staff mix, and lower total and direct care costs.

RESULTS

The intervention did improve quality of care (P = .02); there were improvements in pressure ulcers (P = .05) and weight loss (P = .05). Organizational working conditions, staff retention, staffing, and staff mix and most costs were not affected by the intervention. Leadership turnover was surprisingly excessive in both intervention and control groups.

CONCLUSION AND IMPLICATIONS

Some facilities that are in need of improving quality of care and resident outcomes are able to build the organizational capacity to improve while not increasing staffing or costs of care. Improvement requires continuous supportive consultation and leadership willing to involve staff and work together to build the systematic improvements in care delivery needed. Medical directors in collaborative practice with advanced practice nurses are ideally positioned to implement this low-cost, effective intervention nationwide.

[Risk factors contributing to insufficient water intake in elderly living in nursing homes and long-term care units: a review of the literature]

Elderly living in nursing homes and long-term care units are well-known to be vulnerable to dehydration. Insufficient water intake contributes to suboptimal hydration status and leads to decreased quality of life and global health status. Based on published studies, 32 to 96% of nursing home residents had insufficient water intake and more than 50% drank less than 1.5L per day. Risk factors contributing to decreased water intake in nursing home residents can be divided into two categories, depending whether they apply to the individuals per se (individual factors) or their social and institutional environment (environmental factors). Water intake is associated with meals and medication administration frequency. Diminished thirst sensation, intentional fluid restriction, dysphagia and functional dependency are individual factors recognized as most contributing to decreased water intake. Lack of familial support and insufficient staff are also important since they can contribute to decreased patients' assistance. Dietitians can play a fundamental role in preventing suboptimal hydration status by identifying risk factors that are known to compromise individual's water intake and by implementing corrective measures.

A controlled trial of an intervention to improve urinary and fecal incontinence and constipation

OBJECTIVES

To evaluate effects of a multicomponent intervention on fecal incontinence (FI) and urinary incontinence (UI) outcomes.

DESIGN

Randomized controlled trial.

SETTING

Six nursing homes (NHs).

PARTICIPANTS

One hundred twelve NH residents.

INTERVENTION

Intervention subjects were offered toileting assistance, exercise, and choice of food and fluid snacks every 2 hours for 8 hours per day over 3 months.

MEASUREMENTS

Frequency of UI and FI and rate of appropriate toileting as determined by direct checks from research staff. Anorectal assessments were completed on a subset of 29 residents.

RESULTS

The intervention significantly increased physical activity, frequency of toileting, and food and fluid intake. UI improved (P=.049), as did frequency of bowel movements (P<.001) and percentage of bowel movements (P<.001) in the toilet. The frequency of FI did not change. Eighty-nine percent of subjects who underwent anorectal testing showed a dyssynergic voiding pattern, which could explain the lack of efficacy of this intervention program alone on FI.

CONCLUSION

This multicomponent intervention significantly changed multiple risk factors associated with FI and increased bowel movements without decreasing FI. The dyssynergic voiding pattern and rectal hyposensitivity suggest that future interventions may have to be supplemented with bulking agents (fiber), biofeedback therapy, or both to improve bowel function.

Cost-effectiveness of nutrition interventions in nursing home residents: a pilot intervention

OBJECTIVES

Unintentional weight loss is a prevalent and costly clinical problem among nursing home (NH) residents. One of the most common nutrition interventions for residents at risk for weight loss is oral liquid nutrition supplementation. The purpose of this study was to determine the cost effectiveness of supplements relative to offering residents' snack foods and fluids between meals to increase caloric intake.

DESIGN

Randomized, controlled trial.

SETTING

Three long-term care facilities.

PARTICIPANTS

Sixty-three long-stay residents who had an order for nutrition supplementation.

INTERVENTION

Participants were randomized into one of three groups: (1) usual NH care control; (2) supplement, or (3) between-meal snacks. For groups two and three, trained research staff provided supplements or snacks twice daily between meals, five days per week, for six weeks with assistance and encouragement to promote consumption.

MEASUREMENTS

Research staff observed residents during and between meals for two days at baseline, weekly, and post six weeks to estimate total daily caloric intake. For both intervention groups, research staff documented residents' caloric intake between meals from supplements or snack items, refusal rates and the amount of staff time required to provide each intervention.

RESULTS

Both interventions increased between meal caloric intake significantly relative to the control group and required more staff time than usual NH care. The snack intervention was slightly less expensive and more effective than the supplement intervention.

CONCLUSIONS

Offering residents a choice among a variety of foods and fluids twice per day may be a more effective nutrition intervention than oral liquid nutrition supplementation.
