Prevalence and Risk Factors of Dehydration Among Nursing Home Residents: A Systematic Review

Prevalence and risk factors associated with dehydration of patients with dysphagia in eastern China: A cross-sectional study

AIMS

Dehydration is one of the common complications of dysphagia and poses significant risks including hospitalization and mortality, but the relationship between dysphagia and dehydration has received little attention. This study aims to determine the prevalence and risk factors for dehydration of patients with dysphagia in eastern China, and to provide reference for early identification and prevention of dehydration.

METHODS

A descriptive, cross-sectional design was conducted. Three hundred and thirty-seven (n = 337) patients with dysphagia participated in the study between August and December 2022. Information relating to participants' demographic variables, nutrition, cognition, functional, hydration status and fluid intake was collected. Univariate analysis was used to examine related impact factors, and then binary logistic regression analysis was conducted to determine reliable impact factors.

RESULTS

Among 337 patients with dysphagia, the average age was 63.47 ± 16.96, most participants were male (72.1%) and married (91.7%). The prevalence of dehydration was calculated to be 43.9%, the mean plasma osmolality score was 293.53 mmol/L. Diseases with the highest prevalence were stroke (78.3%), followed by hypertension (63.5%). The risk for dehydration increased with older age, usage of more medicines such as diuretics and beta-blockers, worse functional status and lower fluid intake.

CONCLUSION

This study found a high percentage of dehydration in patients with dysphagia. Findings can provide a basis for targeted nursing interventions for clinical prevention and treatment of dehydration.

Associations Between Eating, Mobility, and Toileting Functional Dependence and COVID-19 Symptoms

OBJECTIVES

The first goal of this study was to explore associations between functional dependence levels during activities of daily living (eg, functional mobility, eating, and toileting) before COVID-19 and presence of COVID-19 symptoms (eg, fever, dehydration, lethargy, and shortness of breath) during illness. The second goal of this study was to explore associations between presence of specific COVID-19 symptoms and level of functional decline from before to after illness.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

A total of 375 residents at a single skilled nursing facility in New York City.

METHODS

Data were extracted from the Minimum Data Set 3.0 and chart reviews. Multiple linear regressions analyzed relationships between baseline functional dependence in eating, functional mobility, and toileting and presence of dehydration, lethargy, shortness of breath, and fever. Ordinal linear regressions analyzed associations between COVID-19 symptom presence and changes in functional dependence from before to after illness.

RESULTS

Pre-COVID-19 eating dependence was significantly associated with dehydration during COVID-19. Dehydration during COVID-19 was significantly associated with greater functional declines in functional mobility from before to after illness. Shortness of breath was significantly associated with increased functional declines in eating and functional mobility.

CONCLUSIONS AND IMPLICATIONS

Patients with COVID-19 should be monitored for shortness of breath and dehydration, as these symptoms are associated with functional decline. Individuals experiencing functional decline before COVID-19 onset are especially vulnerable to these symptoms. Future research should further explore the relationship between functional status and COVID-19 symptoms.

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.

Palliative Care in Nursing Home Residents with Young-Onset Dementia: Professional and Family Caregiver Perspectives

BACKGROUND

The evidence underpinning palliative care in dementia is mostly based on research in older populations. Little is known about the palliative care needs of people with young-onset dementia (YOD).

OBJECTIVE

To describe palliative care practices including advance care planning (ACP) in people with YOD residing in Dutch nursing homes.

METHODS

The study presents baseline questionnaire data from an observational cohort study. Physicians, family caregivers, and nursing staff completed questionnaires about 185 residents with YOD. The questionnaires included items on sociodemographics, quality of life measured with the quality of life in late-stage dementia (QUALID) scale, dementia-related somatic health problems, symptoms, pain medication, psychotropic drugs, and ACP.

RESULTS

The mean age was 63.9 (SD 5.8) years. Half (50.3%) of them were female. Alzheimer's disease dementia (42.2%) was the most prevalent subtype. The mean QUALID score was 24.0 (SD 7.9) as assessed by family caregivers, and 25.3 (SD 8.6) as assessed by the nursing staff. Swallowing problems were the most prevalent dementia-related health problem (11.4%). Agitation was often reported by physicians (42.0%) and nursing staff (40.5%). Psychotropics were prescribed frequently (72.3%). A minority had written advance directives (5.4%) or documentation on treatment preferences by the former general practitioner (27.2%). Global care goals most often focused on comfort (73.9%). Proportions of do-not-treat orders were higher than do-treat orders for all interventions except for hospitalization and antibiotics.

CONCLUSIONS

ACP must be initiated earlier, before nursing home admission. A palliative approach seems appropriate even though residents are relatively young and experience few dementia-related health problems.

The prevalence of chronic dehydration and associated with cardiometabolic risks among agriculture and aquaculture workers

Background

Chronic dehydration is associated with complications and mortality in acute ischemic stroke patients. Prior literature indicates that farmers and fishery workers are commonly affected by cardiometabolic diseases and there is a need for early prevention of stroke. This study explores the prevalence of dehydration and the association of cardiometabolic risk profiles in agricultural and aquaculture workers.

Methods

We conducted a community-based, cross-sectional study of agriculture and aquaculture workers in Yunlin County of Taiwan between August 1 and December 31, 2021. Data on demographic characteristics and health-related lifestyles were collected through one-on-one interviews using a questionnaire. The threshold for dehydration is defined as serum osmolality ≥295 mOsm/kg, and physiological biomarkers were collected from a collaborating hospital. Multivariable logistic regression analyses adjusted for demographic characteristics were performed to investigate the association between dehydration levels, cardiometabolic risks, and health-related behaviors.

Results

A total of 962 Taiwanese agriculture and aquaculture workers who were predominantly women (65%) with a mean age of 64 years (SD = 13.8) were enrolled. The findings showed a high prevalence of dehydration (36%), metabolic syndrome (44.5%), abnormal waist circumference (64.4%), and abnormal blood pressure (68.5%). Multivariate logistic regression demonstrated that dehydration was significantly associated with metabolic syndrome (p < 0.001), 10-year stroke risk prediction (p < 0.001), and an unhealthy lifestyle (p < 0.001).

Conclusion

The prevalence of chronic dehydration was higher in Taiwanese agriculture and aquaculture workers, which was significantly associated with cardiometabolic risks and unhealthy lifestyles.

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.

Prevalence and Risk Score for Hypertonic Dehydration among Community-Dwelling Older Adults: An Analysis of the Bangkok Falls Study

INTRODUCTION

Dehydration is associated with morbidity, and many factors affect dehydration in older adults including age and medication use. This study determined the prevalence of hypertonic dehydration (HD) and factors affecting HD in older adults and developed a risk score (a set of consistent weights that assign a numerical value to each risk factor) which is potentially useful in predicting HD among community-dwelling Thai older adults.

METHODS

Data were obtained from a cohort study of community-dwelling older adults aged ≥60 years in Bangkok, Thailand, between October 1, 2019, and September 30, 2021. Current HD was defined as a serum osmolality >300 mOsm/kg. Univariate and multivariate logistic regression analyses were used to identify factors associated with current and impending HD. The risk score for current HD was developed based on the final multiple logistic regression model.

RESULTS

A total of 704 participants were included in the final analysis. In this study, 59 (8.4%) participants had current HD and 152 (21.6%) had impending HD. We identified three risk factors for HD in older adults: age ≥75 years (adjusted odds ratio [aORs] 2.0, 95% confidence interval [CI]: 1.16-3.46), underlying diabetes mellitus (aORs 3.07, 95% CI: 1.77-5.31), and use of β-blocker medication (aORs 1.98, 95% CI: 1.04-3.78). The increasing risks of current HD with increasing risk scores were 7.4% for a score of 1, 13.8% for a score of 2, 19.8% for a score of 3, and 32.8% for a score of 4.

CONCLUSION

One-third of the older adults in this study had current or impending HD. We identified risk factors for HD and created a risk score for HD in one group of community-dwelling older adults. Older adults with risk scores of 1-4 were at 7.4%-32.8% risk for current HD. The clinical utility of this risk score requires further study and external validation.

Malnutrition in older adults

Malnutrition is a highly prevalent condition in older adults, and poses a substantial burden on health, social, and aged-care systems. Older adults are vulnerable to malnutrition due to age-related physiological decline, reduced access to nutritious food, and comorbidity. Clinical guidelines recommend routine screening for malnutrition in all older adults, together with nutritional assessment and individually tailored nutritional support for older adults with a positive screening test. Nutritional support includes offering individualised nutritional advice and counselling; oral nutritional supplements; fortified foods; and enteral or parenteral nutrition as required. However, in clinical practice, the incorporation of nutritional guidelines is inadequate and low-value care is commonplace. This Review discusses the current evidence on identification and treatment of malnutrition in older adults, identifies gaps between evidence and practice in clinical care, and offers practical strategies to translate evidence-based knowledge into improved nutritional care. We also provide an overview of the prevalence, causes, and risk factors of malnutrition in older adults across health-care settings.

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.

Dehydration and hospital-associated disability in acute hospitalized older adults

PURPOSE

Dehydration is highly prevalent in hospitalized older adults and has been linked to poor outcomes. It is considered a modifiable factor, so early identification and intervention may avoid adverse events and improve quality of life after discharge. Hospital-associated disability (HAD) is known to be a poor prognostic factor and can be categorized into mobility impairment and self-care impairment in setting goals for management. Few studies have directly examined the association between dehydration and HAD and therefore here we examined whether dehydration is a predictor of HAD categorized into mobility and self-care impairment among acute hospitalized older adults.

METHODS

Patients aged 65 years or older who were admitted to the geriatric ward of an acute hospital were recruited for this prospective cohort study. Estimated serum osmolarity > 300 mOsm/kg was defined as current dehydration. HAD was assessed between baseline and discharge and at 3 months after discharge, and was evaluated separately for mobility and self-care impairments.

RESULTS

In total, 192 patients (mean age, 84.7 years; male, 41.1%; dehydration, 31.3%) were analyzed. The occurrence of HAD was significantly higher in the dehydrated group than in the non-dehydrated group (42.4% vs 26.5%) from baseline to 3 months after discharge. In multiple logistic regression analysis, dehydration was significantly associated with HAD in self-care from baseline to 3 months after discharge (odds ratio, 2.25; 95% confidence interval, 1.03-4.94).

CONCLUSIONS

Dehydration could predict the occurrence of HAD in acute hospitalized older adults. A multifaceted approach may be necessary to improve the management of dehydration in these patients.

Dehydration in geriatrics: consequences and practical guidelines

PURPOSE OF REVIEW

Geriatric dehydration is a widespread and under recognized problem. The purpose of this review was to examine the latest evidence regarding geriatric dehydration and provide practical guidance for health professionals.

RECENT FINDINGS

This review covers evidence from the past 2 years and shows that geriatric dehydration is not benign and is associated with significant personal distress, as well as negative economic and health system consequences. New guidance on nutrition and hydration in the elderly recommend against the use of skin turgor, dry mouth, urine colour or specific gravity to determine hydration status in the elderly. Instead, serum osmolality is considered the gold standard.

SUMMARY

Strategies to prevent and manage geriatric dehydration should differ depending on aetiology (low intake, volume depletion or both). Widespread dissemination and implementation of innovative strategies that target improved access to fluids, and systems change to enable rapid and accurate identification and treatment are required.

Dehydration risk factors and outcomes in older people in rural areas

Objective: To determine the risk factors for dehydration in elderly people in one of Elbehira Governorate’s villages.

Methods: A descriptive correlational design was utilized in this study. The study was conducted at Elnemaria village, Markaz Abo Elmatamir, Elbehira Governorate, Egypt. Data were collected using 3 tools: a structured interviewing questionnaire, a dehydration knowledge questionnaire, and a dehydration risk appraisal checklist.

Results: The study found that 29.5% of the participants were aged between 65 and 70. Males constituted 51% of the study participants. The majority of the study participants regularly took anti-acids, anti-inflammatory drugs, and diuretics. Among the elderlies comprising the respondents, 40% had a low level of knowledge regarding dehydration. More than half of the study subjects were at moderate risk for dehydration.

Conclusions: The study showed that half of the participants had diabetes and a medium level of information about dehydration. The study also showed in general that the elderly in the village are exposed to a moderate dehydration rate, and there is also a strong relationship between taking different types of medication and the occurrence of dehydration.

Detecting low-intake dehydration using bioelectrical impedance analysis in older adults in acute care settings: a systematic review

BACKGROUND

Dehydration is a frequent cause of excess morbidity and poor health outcomes, particularly in older adults who have an increased risk of fluid loss due to renal senescence, comorbidities, and polypharmacy. Detecting dehydration is key to instigating treatment to resolve the problem and prevent further adverse consequences; however, current approaches to diagnosis are unreliable and, as a result, under-detection remains a widespread problem. This systematic review sought to explore the value of bioelectrical impedance in detecting low-intake dehydration among older adults admitted to acute care settings.

METHODS

A literature search using MEDLINE, EMBASE, CINAHL, Web of Science, and the Cochrane Library was undertaken from inception till May 2022 and led to the eventual evaluation of four studies. Risk of bias was assessed using the Cochrane tool for observational studies; three studies had a high risk of bias, and one had a low risk. Data were extracted using systematic proofs. Due to insufficient reporting, the data were analysed using narrative synthesis.

RESULTS

One study showed that the sensitivity and specificity of bioelectrical impedance in detecting low-intake dehydration varied considerably depending on the total body water percentage threshold used to ascertain dehydration status. Other included studies supported the technique's utility when compared to conventional measures of hydration status.

CONCLUSIONS

Given the scarcity of literature and inconsistency between findings, it is not possible to ascertain the value of bioelectrical impedance for detecting low-intake dehydration in older inpatients.

Learning from complaints to the Health and Disability Commission Office: A case study into indicators of deterioration in aged residential care organisations in New Zealand

OBJECTIVE

To identify trends in complaints received by the Health and Disability Commissioner (HDC) about aged residential care (ARC) facilities in order to learn from and implement positive changes in care.

METHODS

A case study of 24 deidentified publicly available HDC cases across three large New Zealand ARC organisations was completed. Cross-case analysis first involved analysis of each case individually and then compared all cases using inductive thematic analysis with the intention of drawing a single set of conclusions.

RESULTS

The speed at which the events occurred was contributory to the complaint, with 58% of the cases being rapid in nature and with sepsis being the predominant contributing factor to rapid decline and death. Six main diagnoses were indicators of deterioration: nutrition/hydration was indicated in 22% of the cases, followed by sepsis 17%, wounds 17%, UTI/renal issues 15%, falls 15% and respiratory issues 15%.

CONCLUSIONS

Trends in Health and Disability complaints across multiple organisations can become a powerful tool for widespread quality improvement. This review highlights that the speed of deterioration triggered many complaints, especially in cases of sepsis which is possibly overlooked as a contributing problem. Also, that nutrition/hydration was indicated in many complaints and is an important condition-indicator. Trends in complaints are not generalisable to all large organisations; however, they can be applied to individual facilities.

Reimagining Nutrition Care and Mealtimes in Long-Term Care

Poor food and fluid intake and subsequent malnutrition and dehydration of residents are common, longstanding challenges in long-term care (LTC; eg, nursing homes, care homes, skilled nursing facilities). Institutional factors like inadequate nutrition care processes, food quality, eating assistance, and mealtime experiences, such as staff and resident interactions (ie, relationship-centered care) are partially responsible and are all modifiable. Evidence-based guidelines on nutrition and hydration for older adults, including those living with dementia, outline best practices. However, these guidelines are not sector-specific, and implementation in LTC requires consideration of feasibility in this setting, including the impact of government, LTC home characteristics, and other systems and structures that affect how care is delivered. It is increasingly acknowledged that interconnected relationships among residents, family members, and staff influence care activities and can offer opportunities for improving resident nutrition. In this special article, we reimagine LTC nutrition by reframing the evidence-based recommendations into relationship-centered care practices for nutrition care processes, food and menus, eating assistance, and mealtime experience. We then expand this evidence into actions for implementation, rating these on their feasibility and identifying the entities that are accountable. A few of the recommended activities were rated as highly feasible (6 of 27), whereas almost half were rated moderate (12/27) and the remainder low (9/27) owing to the need for additional staff and/or expert staff (including funding), or infrastructure or material (eg, food ingredients) investment. Government funding, policy, and standards are needed to improve nutrition care. LTC home leadership needs to designate roles, initiate training, and support best practices. Accountability will result from enforcement of policies through auditing of practice. Further evidence on these desirable nutrition care and mealtime actions and their benefit to residents' nutrition and well-being is required.

Admission Dehydration Status Portends Adverse Short-Term Mortality in Patients with Spontaneous Intracerebral Hemorrhage

The impact of dehydration at admission of patients with spontaneous intracerebral hemorrhage (ICH) on short-term mortality remains ambiguous due to scarce data. All of the consecutive patients with spontaneous ICH, who were referred to our neurovascular center in 2018/19, were assessed for hydration status on admission. Dehydration was defined by a blood urea-to-creatinine ratio > 80. In a cohort of 249 patients, 76 patients (31%) were dehydrated at the time of admission. The following factors were significantly and independently associated with increased 30-day mortality in multivariate analysis: “signs of cerebral herniation” (p = 0.008), “initial midline shift > 5 mm” (p < 0.001), “ICH score > 3” (p = 0.007), and “admission dehydration status” (p = 0.007). The results of the present study suggest that an admission dehydration status might constitute a significant and independent predictor of short-term mortality in patients with spontaneous ICH.

Narrative Review of Low-Intake Dehydration in Older Adults

Low-intake dehydration is a common and often chronic condition in older adults. Adverse health outcomes associated with low-intake dehydration in older adults include poorer cognitive performance, reduced quality of life, worsened course of illness and recovery, and a high number of unplanned hospital admissions and increased mortality. The subjective methods to assess (risk of) dehydration are not reliable, and the evidence about preventive measures are also limited. So is the knowledge about the optimal intake of beverages per day. This narrative review presents the state of the science on the role of low intake hydration in older adults. Despite its simple cause—the inadequate intake of beverages—low-intake dehydration appears to be a very complex problem to address and much more research is needed in the area. Based on the existing evidence, it seems necessary to take setting specific differences and individual problems and needs into account to tackle dehydration in older adults. Further, it is necessary to increase awareness of the prevalence and severity of low-intake dehydration among older adults and in nursing staff in care homes and hospitals as well as among caregivers of older adults living at home.

Dehydration in the nursing home: Recognition and interventions taken by Dutch nursing staff

Aims

To examine which signs/symptoms registered nurses (RNs) and certified nurse assistants (CNAs) (nursing staff) in Dutch nursing homes associate with dehydration, if they observe these signs/symptoms themselves and what they do after observing them.

Design

A cross‐sectional study.

Methods

In February 2020, using an online questionnaire based on a diagnostic strategy to diagnose dehydration, nursing staff was asked: (1) which signs/symptoms they associate with dehydration; (2) if they observe these signs/symptoms themselves; and (3) which actions they take after observing these signs/symptoms in a resident. Descriptive statistics and Chi‐square statistics were used to describe the answers and explore significant differences between groups.

Results

In total, 250 RNs and 226 CNAs participated. Among RNs, 67%–99% associated the signs/symptoms of the strategy to dehydration compared with 45%–98% of the CNAs. RNs and CNAs often indicated to observe signs/symptoms from the strategy themselves (80.1% and 92.6%), but they also often relied on information given by other care professionals and the informal caregiver. Interventions taken were mainly focused on communicating findings to colleagues.

Conclusion

Many signs/symptoms from the diagnostic strategy trigger nursing staff to think of dehydration. Results also show that a variety of formal and informal caregivers are involved in dehydration care. As RNs and CNAs did often not receive dehydration training after entering workforce, this could have limited their ability to recognize signs/symptoms related to dehydration. To ensure timely recognition of dehydration, a clear description of roles and responsibilities about dehydration care in, and between, formal and informal caregivers is essential with structurally embedded dehydration training in the nursing home.

Impact

Tackling dehydration in the nursing home requires interdisciplinary collaboration and communication with family members. Without clear roles and responsibilities, a risk of dehydration can be left unattended.

Optimizing mealtime care for people with dementia from the perspective of formal caregivers: A systematic review of qualitative research

BACKGROUND

As dementia progresses, people with dementia experience many problems during mealtimes that seriously affect their physical, psychological, and social health and quality of life. Formal caregivers play an important role in optimizing mealtime care.

OBJECTIVE

To systematically review and synthesise relevant qualitative studies exploring the experience and perceptions of formal caregivers regarding optimizing mealtime care for people with dementia.

DESIGN

A systematic review of qualitative research.

DATA SOURCES

The PubMed, Web of Science, Cochrane Library, Embase, CINAHL, CNKI, WanFang and Vip databases were systematically searched.

REVIEW METHODS

Two reviewers independently screened the titles and abstracts, extracted the data and performed critical appraisals of each included study. The data synthesis was conducted using thematic analysis.

FINDINGS

A total of 10 studies were included. The formal caregivers included nursing assistants, nurses, speech and language therapists, nursing students, dietitians, a social worker, a professional educator, physiotherapists, health care aides, kitchen staff, diversional therapy assistants and other unidentified care staff. The findings were synthesised into the following 3 analytical themes: (1) tailored rather than standardized; (2) emotional nurturance; and (3) beyond the individual level.

CONCLUSIONS

Mealtimes involve complex physiological and psychological processes. Formal caregivers should develop tailored care practices based on individual patients' preferences and needs. Emotional connection plays a key role and has a positive impact on the mealtime experience. Further research is needed to explore the specific effects of emotional connections on optimizing mealtime care.

Mortality of older acutely admitted medical patients after early discharge from emergency departments: a nationwide cohort study

Background

The mortality of older patients after early discharge from hospitals is sparsely described. Information on factors associated with mortality can help identify high-risk patients who may benefit from preventive interventions. The aim of this study was to examine whether demographic factors, comorbidity and admission diagnoses are predictors of 30-day mortality among acutely admitted older patients discharged within 24 h after admission.

Methods

All medical patients aged ≥65 years admitted acutely to Danish hospitals between 1 January 2013 and 30 June 2014 surviving a hospital stay of ≤24 h were included. Demographic factors, comorbidity, discharge diagnoses and mortality within 30 days were described using data from the Danish National Patient Registry and the Civil Registration System. Cox regression was used to estimate adjusted hazard ratios (aHR) with 95% confidence intervals (CI) for all-cause mortality.

Results

A total of 93,295 patients (49.4% men) with a median age of 75 years (interquartile range: 69–82 years), were included. Out of these, 2775 patients (3.0%; 95% CI 2.9–3.1%) died within 30 days after discharge. The 30-day mortality was increased in patients with age 76–85 years (aHR 1.59; 1.45–1.75) and 86+ years (aHR 3.35; 3.04–3.70), male gender (aHR 1.22; 1.11–1.33), a Charlson Comorbidity Index of 1–2 (aHR 2.15; 1.92–2.40) and 3+ (aHR 4.07; 3.65–4.54), and unmarried status (aHR 1.17; 1.08–1.27). Discharge diagnoses associated with 30-day mortality were heart failure (aHR 1.52; 1.17–1.95), respiratory failure (aHR 3.18; 2.46–4.11), dehydration (aHR 2.87; 2.51–3.29), constipation (aHR 1.31; 1.02–1.67), anemia (aHR 1.45; 1.27–1.66), pneumonia (aHR 2.24; 1.94–2.59), urinary tract infection (aHR 1.33; 1.14–1.55), dyspnea (aHR 1.57; 1.32–1.87) and suspicion of malignancy (aHR 2.06; 1.64–2.59).

Conclusions

Three percent had died within 30 days. High age, male gender, the comorbidity burden, unmarried status and several primary discharge diagnoses were identified as independent prognostic factors of 30-day all-cause mortality.

A framework for delivering nursing care to older adults with COVID-19 in nursing homes

Public health emergencies threaten the lives of U.S. citizens, often in disproportionate ways. Hardest hit are vulnerable populations of older adults (OAs) residing in nursing homes (NHs), who comprised nearly 43% of all deaths from COVID‐19 in NHs in 2020. New Jersey (NJ) ranks #2 nationally behind New York with the highest numbers of resident deaths; more than 50% of all COVID‐19‐related deaths in NJ have occurred in NHs. This public health emergency has prompted investigators to evaluate existing structural, resident, process of care, regulatory, and policy characteristics that have impacted the delivery of nursing care within NJ NHs. In this manuscript, we discuss data from NJ NHs during COVID‐19, drawing from publicly available data, state reports, and the geriatric literature to offer recommendations. Based on evidence‐based practices (EBPs), we present a series of recommendations to modify existing contextual factors in NHs to best prepare for the next health disaster.

[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.

Informal dementia caregivers' experiences and perceptions about mealtime care: A qualitative evidence synthesis

AIMS

To systematically identify, evaluate and synthesize the available qualitative evidence on the mealtime care experiences of informal caregivers of people with dementia.

DESIGN

A qualitative evidence synthesis using the Thomas and Harden method.

DATA SOURCES

All qualitative and mixed-method studies in English and Chinese were retrieved from PubMed, Web of Science, Embase, Cochrane, CINAHL, CNKI, WanFang, and Vip from the inception of each database until November 2019.

REVIEW METHODS

Two researchers independently selected the studies using qualitative assessment and review instruments for quality evaluation and thematic synthesis for the data analysis.

RESULTS

Ten studies were chosen for this review. The analytical themes identified included injecting a new element, moving forward in the challenge and external supports facilitating better coping.

CONCLUSION

Community nurses should effectively use resources to provide food-related information and services to families with dementia. Future research should combine informal caregiver experiences and clinical skills to develop high-quality interventions to improve the quality of mealtimes.

IMPACT

The findings established that informal caregivers experienced not only changes in their roles and concerns but also emotional changes. Informal caregivers develop different coping strategies to adapt to feeding issues without professional support. Although informal caregivers attach great importance to mealtimes and nutrition issues, they experience a lack of information and support services. Community nurses can provide more economical, practical, and accessible information resources based on informal caregivers' perceptions of mealtime care. Future interventions need to be more aware of the importance of dyad or family-centred support services.

Diagnosing dehydration in the nursing home: international consensus based on a modified Delphi study

Aim

To assess which method (or combination of methods) are relevant and feasible to diagnose dehydration in nursing home residents.

Findings

International experts agreed on the relevance and feasibility of 9 anamnestic items, 8 physical symptoms and 3 blood tests to diagnose dehydration. This resulted in a diagnostic strategy consisting of a suspicion phase (including anamnestic items and physical symptoms) and a confirmation phase (including blood tests).

Message

This is the first study reaching international consensus about a strategy to diagnose dehydration in the nursing home.

Purpose

Even though dehydration is a big problem among nursing home residents, a universally agreed method to diagnose dehydration among nursing home residents is missing. Therefore, this study aimed to establish consensus on a method to diagnose dehydration in this population.

Methods

Using an international Delphi study, 53 experts (physicians and advanced nurse practitioners) were asked to judge various methods to diagnose dehydration on relevance and feasibility in the nursing home. Based on the methods that gained consensus in the first and second round (≥ 75% consensus), a step-by-step diagnostic strategy was developed which was presented to, and judged by, the experts in round three.

Results

After the first and second round, consensus was reached on nine anamnestic items, eight physical symptoms and three blood tests. In the third round, 24 experts agreed with the developed step-by-step diagnostic strategy as a standard to diagnose dehydration in nursing home residents.

Conclusion

This is the first study reaching international consensus on a strategy to diagnose dehydration in the nursing home. This strategy comprehends a presumption phase, where anamnestic items and physical symptoms are examined, followed by a confirmation phase with blood tests to confirm the diagnosis of dehydration. Using this strategy, it is important to take the individual characteristics (e.g. co-morbidity) of the resident and its care environment (e.g. ambient temperature) into account.

Signs and Symptoms of Low-Intake Dehydration Do Not Work in Older Care Home Residents-DRIE Diagnostic Accuracy Study

OBJECTIVES

To assess the diagnostic accuracy of commonly used signs and symptoms of low-intake dehydration in older care home residents.

DESIGN

Prospective diagnostic accuracy study.

SETTING

56 care homes offering residential, nursing, and/or dementia care to older adults in Norfolk and Suffolk, United Kingdom.

PARTICIPANTS

188 consecutively recruited care home residents aged ≥65 years, without cardiac or renal failure and not receiving palliative care. Overall, 66% were female, the mean age was 85.7 years (standard deviation 7.8), and the median Mini-Mental State Examination MMSE score was 23 (interquartile range 18-26).

INDEX TESTS

Over 2 hours, participants underwent double-blind assessment of 49 signs and symptoms of dehydration and measurement of serum osmolality from a venous blood sample. Signs and symptoms included skin turgor; mouth, skin, and axillary dryness; capillary refill; sunken eyes; blood pressure on resting and after standing; body temperature; pulse rate; and self-reported feelings of thirst and well-being.

REFERENCE STANDARD

Serum osmolality, with current dehydration defined as >300 mOsm/kg, and impending dehydration ≥295 mOsm/kg.

OUTCOME MEASURES

For dichotomous tests, we aimed for sensitivity and specificity >70%, and for continuous tests, an area under the curve in receiver operating characteristic plots of >0.7.

RESULTS

Although 20% of residents had current low-intake dehydration and a further 28% impending dehydration, none of the commonly used clinical signs and symptoms usefully discriminated between participants with or without low-intake dehydration at either cut-off.

CONCLUSIONS/IMPLICATIONS

This study consolidates evidence that commonly used signs and symptoms of dehydration lack even basic levels of diagnostic accuracy in older adults, implying that many who are dehydrated are not being identified, thus compromising their health and well-being. We suggest that these tests be withdrawn from practice and replaced with a 2-stage screening process that includes serum osmolarity, calculated from sodium, potassium, urea, and glucose levels (assessed routinely using the Khajuria and Krahn equation), followed by serum osmolality measurement for those identified as high risk (calculated serum osmolarity >295 mmol/L).

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.

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.
