Risk factors associated with dehydration in older people living in nursing homes: Scoping review

The methodological challenges faced when conducting hydration research in UK care homes

BACKGROUND

The evidence base for hydration practice in care homes is underdeveloped. High-quality research is therefore needed to determine what practices support older people with dementia in drinking sufficient fluid. However, methodological developments are needed to be able to do this.

AIM

To highlight the methodological issues researchers encountered during a feasibility cluster, randomised controlled trial of ThinkDrink, a hydration care guide for people with dementia living in UK care homes.

DISCUSSION

This is a challenging area because of the complexity of recruitment, participation and data collection in care homes. Researchers must pay extra attention to rigour and quality in the design of their studies. There may be multiple challenges, so various strategies may be required.

CONCLUSION

It is important that researchers continue to reflect on rigorous approaches to develop evidence in a crucial area of care, despite these challenges.

IMPLICATIONS FOR PRACTICE

Researchers working in complex environments face a variety of challenges to complete methodologically rigorous research. It is important for researchers to be critical of research processes and data, to mitigate and overcome these challenges.

Integration of a new technology into a work system: a case study of a smart drinking glass in French nursing homes

PURPOSE

To reduce the risk of dehydration in older adults, the French company Auxivia has developed a smart drinking glass (SDG) that can measure the amount of water drunk. The present study looked at the various work systems (WSs) designed for use of the SDG in a nursing home. The study's objectives were to (i) determine the WSs' impact on the staff's ability to comply with the device's prerequisites and ensure the device's effective use and (ii) draw up guidelines on designing work systems.

MATERIALS AND METHODS

At three nursing homes in France, two independent observers performed 9 h of observations at each site and a total of 29 interviews.

RESULTS

Decisions concerning implementation and the resulting WSs have an impact on the tasks to be performed, the tasks' inherent constraints and the use of the SDG. It is essential to take account of the sociotechnical system as a whole before integrating a technology. Ideally, the introduction of an SDG will go unnoticed by staff and residents; however, our results emphasize the value of highlighting work constraints via a human factors analysis.

CONCLUSIONS

It is essential to take account of sociotechnical WSs as a whole when integrating a technology.

Factors associated with pressure ulcer and dehydration in long-term care settings in Ontario, Canada

Pressure ulcers and dehydration are common conditions among residents of long-term care facilities that result in negative health effects. They have been associated with signs of neglect and increased 30-day mortality among LTC residents. However, they are both preventable and with proper care can be effectively managed and treated. We conducted a retrospective cohort study to examine factors associated with pressure ulcers and dehydration among long-term care residents in the province of Ontario, Canada. Results indicated that close to one-fifth of residents were dehydrated (17.3%) or had a pressure ulcer (18.9%) during the study period. Advanced age was significantly associated with the presence of pressure ulcers and dehydration for both men and women. However, men were more likely to present with a pressure ulcer while women were more likely to exhibit symptoms of dehydration. Study findings also demonstrate the presence of both conditions being higher in municipal and not-for-profit homes compared to for-profit homes. The significant differences observed in relation to home ownership which require further investigation to identify the most relevant factors in explaining these differences. Overall, pressure ulcers and dehydration are preventable conditions that warrant attention from policymakers to ensure quality of care and resident safety are prioritized.

Intergenerational Programming Increases Solid Food Consumption for Adult Day Center Attendees

We examined whether participation in intergenerational programming would impact daily food and liquid intake for adult day service center (ADSC) participants, many of whom are at risk for malnutrition and dehydration. Data came from 75 ADSC participants who, on average, attended the center for 472.32 days between 2007 and 2018. We analyzed daily data using multilevel modeling, nesting attending days within ADSC participants. On days when participants joined intergenerational programming, they consumed significantly more solid food (β = 1.54, SD = .37, p < .001), but no different liquid (β = -.16, SD = .09, p = .06), than their own average across all days they attended the ADSC. Intergenerational programming may be an effective way to support ADSCs participants' nutrition. Future research is needed to determine the longer-term health benefits of daily increases in food consumption and to explore why intergenerational programming may differentially impact eating and drinking.

Urinary Hydration Biomarkers and Water Sources in Older Adults with Neurocognitive Disorder

The risk of dehydration in older adults with neurocognitive disorder (NCD) is controversial. The purpose of this study was to assess hydration status, its determinants, and water intake sources in older adults with NCD. A sample of 30 participants (≥60 years) was included. Sociodemographic, clinical data and one 24-h urine sample were collected. Urinary osmolality, sodium, potassium, volume, and creatinine were quantified. Inadequate hydration status corresponded to urine osmolality > 500 mOsm/Kg, or a negative Free Water Reserve (FWR). Two 24-h food recalls were used to assess dietary intake and water sources. The adequacy of total water intake (TWI) was estimated according to EFSA. The contribution of food and beverages to TWI was calculated, and their associations with the urinary osmolality median were tested. Of the total number of participants, 30% were classified as having inadequate hydration status, with no differences between sexes. Regarding TWI, 68.4% of women and 77.8% of men did not reach the reference values. Water (23%), followed by soup (17%), contributed the most to TWI, while vegetables (2%) and alcoholic/other beverages (3%) contributed the least. According to the median urinary osmolality, there was no significant difference in sociodemographic/clinical characteristics. It is critical not to overlook hydration in this vulnerable population.

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.

The Effect of EMG Features on the Classification of Swallowing Events and the Estimation of Fluid Intake Volume

Nowadays, society is experiencing an increase in the number of adults aged 65 and over, and it is projected that the older adult population will triple in the coming decades. As older adults are prone to becoming dehydrated, which can significantly impact healthcare costs and staff, it is necessary to advance healthcare technologies to cater to such needs. However, there has not been an extensive research effort to implement a device that can autonomously track fluid intake. In particular, the ability of surface electromyographic sensors (sEMG) to monitor fluid intake has not been investigated in depth. Our previous study demonstrated a reasonable classification and estimation ability of sEMG using four features. This study aimed to examine if classification and estimation could be potentiated by combining an optimal subset of features from a library of forty-six time and frequency-domain features extracted from the data recorded using eleven subjects. Results demonstrated a classification accuracy of 95.94 ± 2.76% and an f-score of 94.93 ± 3.51% in differentiating between liquid swallows from non-liquid swallowing events using five features only, and a volume estimation RMSE of 2.80 ± 1.22 mL per sip and an average estimation error of 15.43 ± 8.64% using two features only. These results are encouraging and prove that sEMG could be a potential candidate for monitoring fluid intake.

Qualitative analysis of a virtual research meeting summarises expert-based strategies to promote hydration in residential care during COVID-19 and beyond

OBJECTIVES

Poor fluid intake is a complex and long-standing issue in residential care, further exacerbated by COVID-19 infection control procedures. There is no consensus on how best to prevent dehydration in residents who vary in their primary reasons for insufficient fluid intake for a variety of reasons. The objectives of this research were to determine expert and provider perspectives on: (1) how COVID-19 procedures impacted hydration in residential care and potential solutions to mitigate these challenges and (2) strategies that could target five types of residents based on an oral hydration typology focused on root causes of low fluid intake.

DESIGN

Qualitative study based on virtual group discussion. The discussion was audiorecorded with supplementary field notes. Qualitative content analysis was completed.

SETTING

Residential care.

PARTICIPANTS

27 invited researcher and provider experts.

RESULTS

Challenges that have potentially impacted hydration of residents because of COVID-19 procedures were categorised as resident (eg, apathy), staff (eg, new staff) and home-related (eg, physical distancing in dining rooms). Potential solutions were offered, such as fun opportunities (eg, popsicle) for distanced interactions; training new staff on how to approach specific residents and encourage drinking; and automatically providing water at meals. Several strategies were mapped to the typology of five types of residents with low intake (eg, sipper) and categorised as: supplies (eg, vessels with graduated markings), timing (eg, identify best time of day for drinking), facility context (eg, identify preferred beverages), socialisation (eg, promote drinking as a social activity) and education (eg, educate cognitively well on water consumption goals).

CONCLUSIONS

COVID-19 has necessitated new procedures and routines in residential care, some of which can be optimised to promote hydration. A variety of strategies to meet the hydration needs of different subgroups of residents can be compiled into multicomponent interventions for future research.

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.

[Analysis of dehydration in older people in a nursing home in Spain: prevalence and associated factors]

Introduction

Background: dehydration in institutionalized elderly people has not been extensively studied. There are not clear data on the Spanish context. Aim: to estimate the prevalence of dehydration and to identify the associated factors in institutionalized older people in a nursing home. Methods: a cross-sectional study was carried out. Dehydration was measured through the colour of urine. For the identification of the associated factors, sociodemographic, clinical, functional, and mental variables were selected. Results: the total sample studied was comprised of 96 individuals with a mean age of 86.6 years (± 7.1), of whom 80.2 % were women. The prevalence of dehydration was 31.3% (95 % CI, 22.0 to 40.6). The factors that were independently associated with dehydration were the presence of sunken eyes (OR = 8.67; p = 0.004), low fluid intake (OR = 3.96; p = 0.041), and both functional (OR = 0.97; p = 0.012) and cognitive (OR = 1.10; p = 0.009) impairment. Conclusions: this study highlights the problem of dehydration in institutionalized older people in Spain. An urine colour table may be used routinely, non-invasively, and cheaply. So, it may well be the best simple method for detecting dehydration in this population. Taking into account that chronic dehydration is most prevalent in elderly people, the identification of associated factors is a key factor for a successful approach.

Chronic Dehydration in Nursing Home Residents

Chronic dehydration mainly occurs due to insufficient fluid intake over a lengthy period of time, and nursing home residents are thought to be at high risk for chronic dehydration. However, few studies have investigated chronic dehydration, and new diagnostic methods are needed. Therefore, in this study, we aimed to identify risk factors for chronic dehydration by measuring serum osmolality in nursing home residents and also to evaluate whether examining the inferior vena cava (IVC) and determining the IVC collapsibility index (IVC-CI) by ultrasound can be helpful in the diagnosis of chronic dehydration. A total of 108 Japanese nursing home residents aged ≥65 years were recruited. IVC measurement was performed using a portable handheld ultrasound device. Fifteen residents (16.9%) were classified as having chronic dehydration (serum osmolality ≥295 mOsm/kg). Multivariate logistic regression analysis showed that chronic dehydration was associated with dementia (odds ratio (OR), 6.290; 95% confidential interval (CI), 1.270–31.154) and higher BMI (OR, 1.471; 95% CI, 1.105–1.958) but not with IVC or IVC-CI. Cognitive function and body weight of residents should be considered when establishing a strategy for preventing chronic dehydration in nursing homes.

Fluid Intake Recommendation Considering the Physiological Adaptations of Adults Over 65 Years: A Critical Review

The aim of this critical review was to clarify recommended fluid intake for older people. A literature search of published articles and guidelines on fluid intake recommendations until April 2020 was carried out using PUBMED, Scopus, Cochrane, and Google Scholar. In this review, we focused on people over 65 years old at different care levels. The results show that the mean fluid intake ranges between 311 and 2390 mL/day. However, it is difficult to know whether this corresponds to the real pattern of fluid intake, due to the variability of data collection methods. With respect to the recommendations, most international organizations do not take into consideration the physiology of ageing or the health problems associated with an older population. In conclusions, we recommend to follow the guideline of the European Society for Clinical Nutrition and Metabolism (ESPEN) and the European Food Safety Authority (EFSA). ESPEN is the only guideline which takes into account age. It is also based on EFSA recommendations. This authority takes into consideration all fluids consumed (ranging from food to fluids). If it is known that around 20% of all fluids consumed come from food, the result would effectively be that the EFSA recommends the same as the ESPEN guidelines: 1.6 L/day for females and 2.0 L/day for males. The findings could help raise the awareness of professionals in the sector with respect to the required fluid intake of the elderly and, in this way, contribute to avoiding the consequences of dehydration.

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.
