Rehabilitation of the Geriatric Dialysis Patient

More Frequent On-Site Dialysis May Hasten Return to Home for Nursing Home Patients with End-Stage Kidney Disease

Key Points

Prior efficacy study—established that more frequent dialysis achieved better outcomes than CONVENTIONAL dialysis in outpatients. We undertook an effectiveness observational on-site nursing home study (N =195) comparing on-site more frequent dialysis with CONVENTIONAL dialysis. More frequent dialysis patients, despite being sicker at baseline, returned home faster than CONVENTIONALLY dialyzed patients without worsened death or hospitalization.

Background

A direct outcome comparison between skilled nursing facility (SNF) patients receiving on-site more frequent dialysis (MFD) targeting 14 hours of treatment over five sessions weekly compared with on-site CONVENTIONAL dialysis for death, hospitalization, and speed of returning home has not been reported.

Methods

From January 1, 2022, to July 1, 2023, in a retrospective prospective observational design, using an intention-to-treat and competing risk strategy, all new admissions for an on-site SNF dialysis service done to nursing homes with on-site MFD were compared with admissions to nursing homes providing on-site CONVENTIONAL dialysis for the outcome goal of 90-day cumulative incidence of discharge to home, while monitoring safety issues represented by the competing risks of hospitalization and death.

Results

In total, 10,246 MFD dialytic episodes and 3451 CONVENTIONAL dialytic episodes were studied in 195 nursing homes in 12 states. At baseline, the MFD population was consistently sicker than CONVENTIONAL dialysis population with a first systolic BP of <100 mm Hg in 13% versus 7.6% (P < 0.001), lower mean hemoglobin (9.3 versus 10.4 g/dl; P < 0.001), lower iron saturation (25.7% versus 26.6%; P = 0.02), higher Charlson score (3.5 versus 3.0; P < 0.001), higher mean age (67.6 versus 66.7; P < 0.001), more complicated diabetes (31% versus 24%; P < 0.001), cerebrovascular disease (12.6% versus 6.8%; P <0.001), and congestive heart failure (24% versus 18%). At 42 days, discharge to home was 25% greater in the MFD than CONVENTIONAL dialysis group (17.5% versus 14%) without worsened hospitalization or death.

Conclusions

Despite a handicap of sicker patients at baseline, real-world application of MFD appears to hasten return to home from SNFs compared with CONVENTIONAL dialysis. The findings suggest that MFD allows for SNF acceptance of sicker patients, presumably permitting earlier discharge from hospital, without safety compromise as measured by death or rehospitalization, benefitting hospitals, patients, and payers.

Health-Related Quality of Life and Disability Among Older New Zealanders With Kidney Failure: A Prospective Study

Background:

Disability is prevalent in individuals with kidney failure and can contribute to significantly reduced quality of life and survival. In older individuals with kidney failure, disability can be caused by a combination of factors, including issues directly related to their kidney disease and/or treatment, including weakness, low energy, and low activity. Few studies have investigated health-related quality of life (HRQoL) as a possible predictor of disability among older individuals experiencing kidney failure.

Objective:

This study aimed to determine if patient-reported HRQoL, and/or other factors at baseline, predicts disability in people with kidney failure, aged ≥65 years, after 12 months of follow-up.

Design:

The DOS65+ study was an accelerated longitudinal cohort design comprising of both cross-sectional and longitudinal components. Participants were eligible if they were aged ≥65 years, had chronic kidney disease stage 5G (CKD 5G) (estimated glomerular filtration rate (eGFR) <15 ml/min/1.73 m²), and had: commenced kidney replacement education, or were on an active conservative pathway, or were newly incident dialysis patients commencing dialysis therapy or prevalent on dialysis.

Setting:

Three New Zealand District Health Board (DHB) nephrology units (Counties Manukau, Hawke’s Bay, and Southern DHB) were involved in the study.

Participants:

Participants were eligible if they were aged ≥65 years, had CKD 5G (eGFR <15 ml/min/1.73 m²), and had: commenced kidney replacement education, or were on an active conservative pathway, or were newly incident dialysis patients commencing dialysis therapy or prevalent on dialysis.

Measurements:

Disability and HRQoL were measured by EQ-5D-3L, a WHO Disability Assessment Schedule (WHODAS) 2.0.

Methods:

Baseline and 12-month data from our longitudinal dialysis outcomes in older New Zealanders’ study were analyzed to determine if HRQoL at baseline predicted disability outcomes 12 months later.

Results:

Of the 223 participants at baseline, 157 participants completed a follow-up interview 12 months later. Individuals with “considerable disability” at baseline had a significantly (86%) higher risk of experiencing “considerable disability” at 12 months compared with those with “lesser/no disability” at baseline. Two thirds of those with  ≥3 comorbidities were experiencing “considerable disability.” In addition, those with problems with EQ-5D-3L self-care, EQ-5D-3L usual activities, and EQ-5D-3L anxiety/depression reported higher rates of disability.

Limitations:

Selection bias is likely to have been an issue in this study as participants were excluded from the follow-up interview if they had an intercurrent illness requiring hospitalization within 2 weeks of the survey interview or if the treating nephrologist judged that the individual’s ability to take part was significantly impaired. Sample size meant there were a limited number of explanatory/confounding variables that could be investigated in the multivariable model.

Conclusions:

EQ-5D-3L mobility and self-care may be useful in predicting subsequent disability for individuals with CKD 5G. Although individuals with kidney failure often experience disability, previous studies have not clearly identified HRQoL or disability as predictors of later disability for individuals with kidney failure. Therefore, we would recommend the assessment of mobility and self-care, in conjunction with existing disabilities in the clinical review and pre-dialysis education of individuals with kidney failure as they approach the need for kidney replacement therapy.

Quality improvement outcomes from the introduction of a geriatrician into a rehabilitation setting

OBJECTIVES

Geriatrician impact on patient and system outcomes in formal rehabilitation settings has not been well described to date. We studied the effect of adding a geriatric medicine consultation service to a geriatric focused rehabilitation setting providing care to dialysis and non-dialysis patients.

DESIGN/SETTING/PARTICIPANTS

A pre- and post-retrospective observational cohort study from January 1, 2009 to June 30, 2019 on all consecutively admitted adults aged 65 and older to general rehabilitation program, and adults aged 60 and older to specialized dialysis rehabilitation program, within a 25 bed general rehabilitation unit in a large urban academic rehabilitation center in Toronto, Ontario. Data were analyzed with quality improvement methodology including Statistical Process Control charts (XmR and U charts).

INTERVENTION

Addition of a geriatric medicine service providing automatic comprehensive geriatric assessment and co-management consultative services for all admitted patients from admission onwards who met criteria for the intervention. The intervention commenced on August 1, 2013.

MEASUREMENTS

Outcome measures were length of stay (days), service interruption frequency, and average functional independence measure (FIM) change (discharge FIM minus admission FIM) which uses the validated FIM score, a marker of functional ability. A 22 point change in FIM score is clinically relevant.

RESULTS

Patient characteristics: general rehabilitation patients (n = 1395, mean age = 79.7, 50.1% female) and dialysis rehabilitation patients (n = 838, mean age = 72.8, 41.8% female). The average FIM change following intervention improved from 20.8 to 29.3 in the general rehabilitation cohort (40.6% improvement, SD = 5.51) and from 22.1 to 30.6 in the dialysis rehabilitation cohort (38.6% improvement, SD = 5.88). Changes in length of stay (24.9%-28.1% reduction) and service interruption frequency (34.3%-49.7% reduction) were also observed.

CONCLUSION

Introduction of a geriatric medicine service for rehabilitation inpatients was associated with significant FIM score improvements. Our results suggest this intervention contributes to important gains in functional independence in reduced time for older adults receiving inpatient rehabilitative care.

The efficacy of rehabilitation for elderly hemodialysis patients: a retrospective, single center study

INTRODUCTION

Chronic kidney disease is associated with an increased risk of vascular events and bone fractures, and its prevalence is increasing. Despite the high frequency of strokes and bone fractures in the hemodialysis (HD) population, the few studies on rehabilitation outcomes in this population are controversial. The current study assessed the efficacy of inpatient rehabilitation for hemodialysis patients.

METHODS

This is a retrospective, observational review of medical records of all chronic HD patients who underwent rehabilitation in Meir Medical Center, from 2008 to 2018. The primary endpoint was functional independence measure (FIM) score at discharge. Secondary endpoints were all-cause mortality, efficiency of rehabilitation and discharge destination from rehabilitation.

RESULTS

During the study period, 162 patients were included in the analysis. 76/81 (93.8%) hemodialysis patients had improvement FIM scores. There were no significant differences in FIM scores at discharge between hemodialysis patients and controls. However, the efficiency of rehabilitation expressed by FIM efficiency (progress measured as FIM gain/length of stay in rehabilitation) was higher in hemodialysis vs. controls. 73% of hemodialysis patients were discharged home. There was no significant difference in discharge destinations between groups. Both 30-day and 1-year mortality after admission to rehabilitation was higher in HD vs. controls (OR 4.97, 95% CI 1.4-18.2, p = 0.008 and OR 4.98, 95% CI 1.8-14.1, p value = 0.001, respectively).

CONCLUSION

Hemodialysis patients may benefit from inpatient rehabilitation. Although mortality was higher, efficacy of rehabilitation for hemodialysis patients is comparable to non-dialysis patients and is no less effective.

Variabilidad intramétodo en medidas del flujo del acceso vascular con termodilución: ¿Un enemigo en los programas de seguimiento?

Objetivo: Analizar el impacto de la variabilidad intramétodo de la Termodilución (TD) en las medidas prospectivas de flujo de acceso (QA) y su relación con los parámetros de seguimiento de primera generación. Método: Estudio prospectivo. Se realizaron 2 mediciones consecutivas de QA (M1 y M2) y un seguimiento (M3) en 6 meses. Se recogieron datos demográficos y parámetros de seguimiento de primera generación. Resultado: Se analizaron 112 fistulas arteriovenosas(FAV). La mediana de la variabilidad generada entre M1 y M2 no difiere del porcentaje de variación de QA a los 6 meses (p=0,123). En el 16,8% (14) de los pacientes el QA ha disminuido más del 25% y en un 28,9% (24) aumentó más del 25%. Se evidenció una ligera tendencia a aumentar el porcentaje de descenso de QA a medida que el flujo de las fístulas es mayor (r=-0,229; p=0,006). Por otra parte, un descenso de QA superior al 25% no se asoció a menor dosis de diálisis (p=0,183), ni ha aumento significativo de la presión venosa dinámica (p=0,823) ni al aumento de incidencias durante la punción (p=0,823). Conclusiones: La presencia de pacientes con aumento de flujo superior a la variabilidad intramétodo y la no asociación entre un descenso superior al 25% y cambios en otros parámetros de seguimiento, hace sospechar la presencia de errores de medición de QA. Frente a ello es conveniente el uso combinado con métodos de primera generación, tanto para establecer el QA basal como para interpretar los descensos en el seguimiento.

Análisis de la calidad de vida del paciente en prediálisis y su relación con la dependencia para las actividades instrumentales de la vida diaria

la salud de los pacientes con enfermedad renal crónica avanzada y determinar su relación con la dependencia para las actividades instrumentales de la vida diaria. Material y Método: Se realizó un estudio descriptivo transversal en el Servicio de Nefrología del Hospital Universitario Reina Sofía de Córdoba, en el que se incluyeron pacientes con enfermedad renal crónica avanzada en estadios 4-5. Se utilizaron los siguientes cuestionarios: KDQOL-SF, para analizar la calidad de vida relacionada con la salud; Lawton y Brody, para dependencia para las actividades instrumentales de la vida diaria. Resultados: Se estudiaron 105 pacientes con una edad de 67,8±15,7 años; 35 mujeres (33,3%). En el KDQOL-SF, las dimensiones más afectadas fueron los Cambios en el estado de salud, Situación laboral, Carga de la enfermedad renal, Salud general, Vitalidad y Rol físico. El 57,1% de la muestra tenían algún grado de dependencia para las actividades instrumentales de la vida diaria. Los pacientes con mayor grado de dependencia presentaron peores puntuaciones en las dimensiones Efectos de la enfermedad renal, Situación laboral, Función cognitiva, Sueño, Función física, Rol físico, Dolor, Función social y Vitalidad. Conclusiones: Los pacientes en prediálisis tienen disminuida la calidad de vida relacionada con la salud en las dimensiones Cambios en el estado de salud, Situación laboral, Carga de la enfermedad renal, Salud general, Vitalidad y Rol físico. Más de la mitad de la muestra presentan algún tipo grado de dependencia para la realización de las actividades instrumentales de la vida diaria.

Evidence supporting the use of a subjective staff evaluation to assess the benefit of rehabilitation in hemodialysis patients undergoing inpatient rehabilitation

Background

We questioned whether the introduction of a subjective evaluation of patient-specific goals, could be used as a valid method to assess the effectiveness of inpatient rehabilitation.

Methods

In this prospective cohort study, all admissions to the UHN hemodialysis rehabilitation service between April 2013 and August 2016 were included. We introduced a system of subjective assessment, performed by the team at the time of admission and discharge. We evaluated Functional Independence Measure (FIM®) score and KDQoL for objective measures of physical function and patient-reported quality of life.

Results

A total of 201 patients were included. The median FIM score at discharge correlated well with the subjective staff evaluation. FIM score changes for those with evaluations for Success, Partial success, and Not Successful were 28 [interquartile range (IQR) 20–34], 24 [IQR18–31], 16 [IQR 11–34] respectively. The median PCS at discharge for those deemed to have Success was 37.4 [IQR31.0, 44.7], and for those with Partial success & Not Successful 28.8 [IQR 22.4, 39.2]. There was no correlation with MCS scores (55.2 [IQR 51.2, 60.2], 58.4 [IQR 50.1, 63.1] respectively).

Conclusions

These results suggest the subjective staff evaluation is a brief but valid assessment of patient outcome for dialysis patients undergoing inpatient rehabilitation.

Disability of Dialysis Patients and the Condition of Blood Vessels

The number of elderly hemodialysis patients is constantly increasing worldwide. This population has a high burden of comorbid conditions, which impair daily activities. The aim of the study was to analyze problems of disability in hemodialysis patients in the context of cardiovascular (CV) complications and vascular condition. In this cross-sectional study, 129 patients (mean age 64.5) were enrolled. The degree of disability in Barthel index (Bi) and 10-year cardiovascular risk (QRISK®3) were assessed. A Mobil-O-Graph monitor was used for measuring hemodynamic parameters. Only 6.2% of patients were professionally active, 19% used a wheelchair for transport, and 16% used crutches. More than half (51%) were independent in everyday activities reaching 80-100 points on Bi. The rest, with Bi < 80, were considered as dependent. The most common causes of disability were CV complications. The independent group (80-100 points) was characterized by significantly lower pulse wave velocity (PWV) and lower QRISK®3 compared to dependent patients. The degree of disability negatively correlated with age, PWV, and QRISK®3. Multivariate logistic regression revealed that disability (Bi < 80) was independently associated with CV events in the past adjusted odds ratio (adj.OR) 4.83 (95% confidence interval (95% CI): 1.74-13.41) and higher PWV adj.OR 1.45 (95% CI: 1.15-1.82). Our results indicate that CV diseases are the most important cause of functional impairment.

Geriatric Assessment and the Relation with Mortality and Hospitalizations in Older Patients Starting Dialysis

BACKGROUND AND OBJECTIVES

A geriatric assessment (GA) is a structural method for identifying frail patients. The relation of GA findings and risk of death in end-stage kidney disease (ESKD) is not known. The objective of the GA in OLder patients starting Dialysis Study was to assess the association of GA at dialysis initiation with early mortality and hospitalization.

DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS

Patients ≥65 years old were included just prior to dialysis initiation. All participants underwent a GA, including assessment of (instrumental) activities of daily living (ADL), mobility, cognition, mood, nutrition, and comorbidity. In addition, a frailty screening (Fried Frailty Index, [FFI]) was applied. Outcome measures were 6- and 12-month mortality, and 6-month hospitalization. Associations with mortality were assessed with cox-regression adjusting for age, sex, comorbidity burden, smoking, residual kidney function and dialysis modality. Associations with hospitalization were assessed with logistic regression, adjusting for relevant confounders.

RESULTS

In all, 192 patients were included, mean age 75 ± 7 years, of whom 48% had ≥3 geriatric impairments and were considered frail. The FFI screening resulted in 46% frail patients. Mortality rate was 8 and 15% at 6- and 12-months after enrolment, and transplantation rate was 2 and 4% respectively. Twelve-month mortality risk was higher in patients with ≥3 impairments (hazard ratio [HR] 2.97 [95% CI 1.19-7.45]) compared to less impaired patients. FFI frail patients had a higher risk of 12-month mortality (HR 7.22 [95% CI 2.47-21.13]) and hospitalization (OR 1.93 [95% CI 1.00-3.72]) compared to fit patients. Malnutrition was associated with 12-month mortality, while impaired ADL and depressive symptoms were associated with 12-month mortality and hospitalization.

CONCLUSIONS

Frailty as assessed by a GA is related to mortality in elderly patients with ESKD. Individual components of the GA are related to both mortality and hospitalization. As the GA allows for distinguishing between frail and fit patients initiating dialysis, it is potentially of added value in the decision-making process concerning dialysis initiation.

Disability in instrumental activities of daily living in hemodialysis patients: Influence on quality of life related to health

INTRODUCTION

Instrumental Activities of Daily Life (IADL) requires a higher level of personal autonomy and interaction with the environment than the basic activities of daily life (BADL). Few studies analyze the deficit on IADL. Early detection is important because an early action can delay the evolution of the dependency process.

AIM

to know the prevalence of functional deficit in IADL of hemodialysis patients, its relationship with the functional deficit in the BADL and its influence on the health related quality of life (HRQoL).

METHODS

Cross-sectional study in 66 patients on HD. Different scales were used: Lawton and Brody (AIVD dependency), Delta (BADL dependency), and COOP-WONCA (HRQOL). Clinical data were collected (age, sex, CKD etiology, months in HD, marital status, employment situation).

RESULTS

80.3% of the patients had some degree of dependence for the IADL (57.5% in moderate/severe degree) and 40.8% for the BADL (9% in moderate/severe degree). There was a correlation between dependence to the BADL and AIVD. Age and employment status influence the dependence on IADL and BADL. Patients with greater dependence on IADL had worse HRQoL (P<.000). The dimensions in which they showed greater differences were "Daily activities", "Social activities" and "Social support".

CONCLUSIONS

HD patients are more dependent on IADL than on ADL and with a higher degree of severity and the level of dependence in both types of activities has important influence on HRQoL. Early detection of the occurrence of disability in the realization of IADL can be used to initiate intervention programs that help to prevent, reverse or delay the progression.

Pilot Intervention Addressing Social Support and Functioning of Low Socioeconomic Status Older Adults With ESRD: The Seniors Optimizing Community Integration to Advance Better Living with ESRD (SOCIABLE) Study

RATIONALE & OBJECTIVE

Older adults with end-stage kidney disease have increased morbidity, fatigue, and decreased physical function, which can inhibit self-care and social engagement. We pilot tested a home-based program to improve physical and social functioning of low socioeconomic status older adults treated with hemodialysis (HD).

STUDY DESIGN

Qualitative study and randomized waitlist control intervention.

SETTING & PARTICIPANTS

Older adult HD patients in Baltimore, MD.

INTERVENTIONS

We identified functional needs and home environmental barriers to social engagement through focus groups; mapped findings onto aspects of an established program, which includes home visits with an occupational therapist, nurse, and handyman to provide ≤$1,300 worth of repairs, modifications, and devices; and piloted the program (Seniors Optimizing Community Integration to Advance Better Living with ESRD [SOCIABLE]) among 12 older adult HD patients. We delivered the services over 5 months in a staggered fashion.

OUTCOMES

Feasibility and acceptability of the intervention and change in disability scores.

RESULTS

Focus group themes included fatigue, lack of social support, and desire to live independently. SOCIABLE pilot participants were recruited from 2 dialysis units and all were African American (50% men); mean age was 69 years. At baseline, the mean disability score for activities of daily living (ADLs) was 4.4 and for instrumental ADLs (IADLs) was 6.3 (both out of a possible 16). Among the 9 participants alive at follow-up, there was 100% intervention completion and outcomes assessment. All treated participants improved a mean score of 2.3 for ADL and 2.6 for IADL disability, and social support and social network scores improved by 4.8 and 4.6, respectively.

LIMITATIONS

Small sample size; all participants were African American.

CONCLUSIONS

A home-based intervention addressing physical and social functioning of low socioeconomic status older adults on HD therapy was feasible and acceptable.

Geriatric Assessment in Elderly Patients with End-Stage Kidney Disease

BACKGROUND/AIMS

Decision-making in elderly patients considering dialysis is highly complex. With the increasing number of elderly with end-stage kidney disease (ESKD), it may be important to assess geriatric impairments in this population. The aim of the Geriatric assessment in OLder patients starting Dialysis (GOLD) study was to assess the prevalence of geriatric impairments and frailty in the elderly ESKD population by means of a geriatric assessment (GA), which is a comprehensive tool for overall health assessment.

METHODS

This study included 285 patients ≥65 years: 196 patients at the time of dialysis initiation and 89 patients who chose maximal conservative management (MCM). The GA assessed cognition, mood, nutritional status, (instrumental) activities of daily living (ADL), mobility, comorbidity burden, quality of life and overall frailty.

RESULTS

The mean age of the participants was 78 years and 36% were women. Of the incident dialysis patients, 77% started haemodialysis and 23% started peritoneal dialysis. Geriatric impairments were highly prevalent in both dialysis and MCM patients. Most frequently impaired geriatric domains in the dialysis group were functional performance (ADL 29%, instrumental ADL (iADL) 79%), cognition (67%) and comorbidity (41%). According to the GA, 77% in the dialysis group and 88% in the MCM group had 2 or more geriatric impairments. In the MCM group, functional impairment (ADL 45%, iADL 85%) was highly prevalent.

CONCLUSIONS

Geriatric impairments are highly prevalent in the elderly ESKD population. Since impairments can be missed when not searched for in regular (pre)dialysis care, the first step of improving nephrologic care is awareness of the extensiveness of geriatric impairment.

Functional impairment and risk of mortality in patients on chronic hemodialysis: results of the Lazio Dialysis Registry

BACKGROUND

Functional impairment is associated with adverse outcomes in older people, as well as in patients on chronic hemodialysis. The aim of this study was to evaluate if functional impairment represents a risk factor for reduced survival in patients on chronic hemodialysis.

METHODS

All incident chronic hemodialysis patients of Lazio, a large region of central Italy, registered in the Dialysis and Transplant Lazio Region Registry (DTLRR) in the period 2008-2013 were considered eligible. Inclusion criteria were: age > 18 years, resident in Lazio, still doing dialysis after 90 days from incidence date, doing hemodialysis or hemodiafiltration treatment for > 9 h/week. Patients were stratified into three classes of functional activity: total autonomy, autonomy in some activities, and not self-sufficient. Functional activity was assessed for each patient by the referring physician for the DTLRR from the ~ 90 hemodialysis units of the Lazio region. Each patient was followed from date of first dialysis treatment to the end of the study (31/12/2015) or death or renal transplant, whichever occurred first. Cox proportional hazard models were performed to obtain mortality hazard ratios (HR), 95% confidence intervals (CI), for each class of functional activity adjusting for sex, age, country of birth, city of residence, body mass index (BMI), type of nephropathy, vascular access, previous nephrology counselling, weekly hours of hemodialysis, serum albumin, hemoglobin, and presence of comorbidities (e.g. vascular diseases, coronary disease, and diabetes).

RESULTS

A total of 3356 patients were studied. In the whole follow-up period, 1622 deaths occurred (48%). Functional impairment was associated with the risk of mortality: compared to 'total autonomy', the HR for 'autonomy in some activities' was 1.30 [95% CI: 1.14-1.49] and for 'not self-sufficient' 1.71 [1.47-1.99] (p for trend < 0.05). The number of evitable deaths attributable to reduced functional activity was 237.

CONCLUSION

Functional impairment represents a risk factor for reduced survival in chronic hemodialysis patients. There is a need for early identification of patients who might benefit from interventions aimed at preventing, reversing or delaying the functional impairment.

Consequences of CKD on Functioning

Chronic kidney disease (CKD) is highly prevalent in the United States and throughout the world,(1) with approximately 13% of adults affected.(2) In addition, according to recent estimates, almost half of patients with CKD stages 3 to 5 are 70 years of age and older.(2) In the United States, the number of prevalent end-stage renal disease cases continues to increase in patients older than age 65. In light of the demographic characteristics of patients with CKD and ESRD, there has been considerable focus on associations between CKD and cardiovascular outcomes.(3) Until recently, less attention had been paid to other consequences of CKD in general and among older individuals with CKD in particular, but there is now solid evidence linking CKD with impairments of physical function, cognitive function, and emotional function and quality of life. This review summarizes available literature on these topics, focusing specifically on physical functioning and frailty, cognitive function, emotional health, including depression and anxiety, and health-related quality of life.

A closer look at the trajectory of physical functioning in chronic hemodialysis

Background

in chronic hemodialysis, physical functioning (PF) is known to be poor. We set out to assess to what extent chronic dialysis patients are able to maintain a good physical condition over time and what the influence of age is on the trajectory of PF.

Methods

we used data form 714 prevalent hemodialysis patients, enrolled in the CONvective TRAnsport STudy (CONTRAST). The PF subscale of the KDQOL SF-36 was assessed at baseline (n = 679) and during 2 years of follow-up (n = 298). Baseline PF score (0-100) was categorized into tertiles (good, intermediate and low). Change of PF of ≥ 5 points was considered clinically relevant. A regression model was applied to assess factors related to 'decline of PF (≥5 points)/low PF (0-33) at follow-up'.

Results

during follow-up, only 15.3 % (1 out of 6) of patients succeeded in maintaining a good physical condition, the remainder deteriorated or died. Of the older patients (≥75) only 3.6% remained in a good physical condition. Factors related to decline/low PF were increasing age (odds ratio [OR] = 1.96 [95% CI: 1.03-3.72] for 65-74 years and OR = 2.38 [95%CI: 1.17-4.84] for ≥75 years compared to <65 years) and albumin (OR = 1.10 [95%CI: 1.01-1.18] per g/L decrease).

Conclusion

very few hemodialysis patients maintain a good physical condition over a 2-year time span. Especially in older patients, physical performance is poor and decline is faster than in the healthy population. These findings should be taken into account when considering dialysis in older patients and more emphasis should be placed to attempts for improving physical condition.

Functional impairment is associated with an increased risk of mortality in patients on chronic hemodialysis

BACKGROUND

Functional impairment is associated with adverse outcomes in older people, as well as in patients on chronic hemodialysis. The aim of the present study was to determine the characteristics associated with functional impairment in chronic hemodialysis, and to evaluate if functional impairment represents a risk factor for reduced survival in chronic hemodialysis.

METHODS

All 132 chronic hemodialysis referring to the Hemodialysis Service of the Catholic University, Rome, Italy between November 2007 and May 2015 were included. All patients underwent comprehensive geriatric assessment; functional ability was estimated using two questionnaires exploring independency in bathing, dressing, toileting, transferring, continence, feeding (ADLs), and independency in using the telephone, shopping, food preparation, housekeeping, laundering, traveling, taking medications, and handling finances (IADLs). Functional impairment was diagnosed in presence of dependence in one or more ADLs/IADLs. Mood was assessed using the 30-item Geriatric Depression Scale. Logistic regression was used to evaluate factors associated with functional impairment. The association between functional impairment and survival was assessed by Cox regression.

RESULTS

ADLs impairment was present in 34 (26 %) participants, while IADLs impairment was detected in 64 (48 %) subjects. After a follow up of 90 months, 55 (42 %) patients died. In logistic regression, depressive symptoms were associated with ADLs and IADLs impairment (OR 1.12; 95 % CI = 1.02-1.23; OR 1.16; 95 % CI = 1.02-1.33; respectively). In Cox regression, ADLs impairment was associated with mortality (HR 2.47; 95 % CI-1.07-5.67) while IADLs impairment was not associated with reduced survival (HR .80; 95 % CI-.36-1.76).

CONCLUSIONS

Functional impairment is associated with depressive symptoms; also, impairment in the ADLs represents a risk factor of reduced survival in chronic hemodialysis. These associations and their potential implication should be assessed in dedicated studies.

Geriatric Assessment, Falls and Rehabilitation in Patients Starting or Established on Peritoneal Dialysis

Individuals aged over 70 years at the time of starting dialysis have a varied and often challenging existence on dialysis. Canadian data suggest those starting dialysis between the ages of 75 and 79 years will have an average life expectancy of 3.2 years, while based on US data, patients can expect an average life expectancy of 25 months. A substantial proportion of these patients will, however, experience transient or permanent loss of personal independence within the first few months to years on dialysis. Preliminary data from patients recently started on peritoneal dialysis (PD) suggest patients and families adapt, but that the adaptation often involves limiting activities and altering the social role the patient has within the family. As data emerge, it will be possible to hypothesize whether this adaptation is beneficial in the long term, or whether these adaptations are permissive, allowing the patient to play a sick role leading to an accelerated transition to frailty and possibly death. Future research will hopefully inform us whether the functional dependency can be identified early and whether it is preventable. In the interim, repair rather than prevention is possible through rehabilitation. We therefore advocate that programs providing PD care consider the integration of protocols whereby patients may undergo formal evaluation to identify those who would benefit from walking or personal care aids, rehabilitation interventions, and, when needed, personal support.

Functional Dependence and Mortality in the International Dialysis Outcomes and Practice Patterns Study (DOPPS)

BACKGROUND

Patients receiving long-term dialysis have among the highest mortality and hospitalization rates. In the nonrenal literature, functional dependence is recognized as a contributor to subsequent disability, recurrent hospitalization, and increased mortality. A higher burden of functional dependence with progressive worsening of kidney function has been observed in several studies, suggesting that functional dependence may contribute to both morbidity and mortality in dialysis patients.

STUDY DESIGN

Prospective cohort study.

SETTING & PARTICIPANTS

7,226 hemodialysis patients from 12 countries in the DOPPS (Dialysis Outcomes and Practice Patterns Study) phase 4 (2009-2011) with self-reported data for functional status.

PREDICTOR

Patients' ability to perform 13 basic and instrumental activities of daily living was summarized to create an overall functional status score (range, 1.25 [most dependent] to 13 [functionally independent]).

OUTCOME

Cox regression was used to estimate the association between functional status and all-cause mortality, adjusting for several demographic and clinical risk factors for mortality. Median follow-up was 17.2 months.

RESULTS

The proportion of patients who could perform each activity of daily living task without assistance ranged from 97% (eating) to 47% (doing housework). 36% of patients could perform all 13 tasks without assistance (functional status = 13), and 14% of patients had high functional dependence (functional status < 8). Functionally independent patients were younger and had many indicators of better health status, including higher quality of life. Compared with functionally independent patients, the adjusted HR for mortality was 2.37 (95% CI, 1.92-2.94) for patients with functional status < 8.

LIMITATIONS

Possible nonresponse bias and residual confounding.

CONCLUSIONS

We found a high burden of functional dependence across all age groups and across all DOPPS countries. When adjusting for several known mortality risk factors, including age, access type, cachexia, and multimorbidity, functional dependence was a strong consistent predictor of mortality.

Ageing Renal Patients: We Need More Collaboration between Geriatric Services and Nephrology Departments

There has been a significant increase in the number of frail older patients diagnosed with advanced chronic kidney disease (CKD) over the past thirty years. These elderly patients have high levels of comorbidity, and as a consequence the face of renal medicine is changing—There is an increasing need to focus on traditionally geriatric areas of expertise such as falls prevention and rehabilitation, and to shift our emphasis onto improving patient well-being rather than longevity. Over the past decade, many nephrologists have found that they are already acting as de facto “amateur geriatricians”. This denies patients both the benefits of specialist geriatric assessment, and equally importantly denies them access to the wider geriatric multidisciplinary team. This article describes the prevalence and underlying causes of the so-called “Geriatric Giants” in patients with advanced CKD, and discusses possible improvements in care that closer working with geriatricians could bring.

The impact of multidisciplinary rehabilitation on the quality of life of hemodialysis patients in Iran

BACKGROUND/PURPOSE

Hemodialysis contributes to changes in lifestyle and the health status of patients. The aim of this study was to evaluate the impact of participatory rehabilitation on the quality of life of patients.

METHODS

This quasi-experimental before and after study was conducted on 30 patients in the hemodialysis center at Hazrat-e-Rasoul Hospital in Javanrood during 2013. The rehabilitation program was executed with participation of experts in the fields of nursing, physiotherapy, and clinical psychology for 8 weeks. The instrument used for data collection was the hemodialysis version of Ferrans and Powers Quality of Life Index (QLI) which was completed by the research assistant by interview before and after the rehabilitation program.

RESULTS

The mean age of patients was 55.8 ± 14.3 years, 60% were male, and 93.3% were married. The average duration of hemodialysis was 3 ± 2.4 years. The quality of life score of all patients before the intervention was between 10 and 19 (moderate level), which after intervention, improved to a good level in half of the patients (p < 0.001).

CONCLUSION

Rehabilitation programs improve the quality of life of hemodialysis patients. By this finding, implementation of rehabilitation programs is recommended in hemodialysis centers with participation of experts from different fields including nurses, physiotherapists, and clinical psychologists.

Dialysis therapies in older patients with end-stage renal disease

Each year a large number of older individuals with advanced renal disease are started on chronic dialysis therapy. Life expectancy is estimated at between 2 and 4 years depending on age, comorbidity, and intensity of medical care required in the weeks around the dialysis start time. Survivors remain at high risk of ongoing morbidity. Regarding quality of life, many older patients express regret over having opted for chronic dialysis therapy and subsequently choose to withdraw from treatment, whereas many others maintain a quality of life similar to that of age-matched peers. Early assessment and ongoing comprehensive geriatric assessment is recommended.

End-stage renal disease in nursing homes: a systematic review

OBJECTIVES/INTRODUCTION

Demand for nursing home (NH) care by patients with end-stage renal disease (ESRD) is likely to increase with growing numbers of older adults initiating chronic dialysis. We completed a systematic review to summarize the literature on NH residents with ESRD.

METHODS

MEDLINE, CINAHL, EMBASE, and relevant conference proceedings were searched to identify articles using the following MESH terms or related key words in the title or abstract: "residential facilities", "renal dialysis", "renal replacement therapy", and "chronic kidney failure". We selected case control, cohort studies, and clinical trials that included older adults with ESRD (defined as those receiving chronic dialysis or those with stage 5 chronic kidney disease) living in residential care facilities. We abstracted information on study design, quality, and results.

RESULTS

Of 198 unique citations identified by the search strategy, 14 articles met eligibility criteria. Most articles were multicenter studies that were conducted in the 1990 s. One study focused on patients with stage 5 chronic kidney disease, and the remaining 13 studies focused on patients receiving chronic dialysis, of which eight studies included only those receiving peritoneal dialysis, four studies included patients receiving both peritoneal dialysis and hemodialysis, and one study included only patients receiving hemodialysis. All studies were observational, no clinical trials were identified, and study design limitations and heterogeneity within study populations were common. Summarizing results across these studies suggests that NH residents with ESRD have limited survival, particularly early after dialysis initiation. Functional impairment is highly prevalent in this population and independently associated with poor outcomes.

CONCLUSIONS

NH residents with ESRD appear to be a particularly vulnerable population, but current information on their prevalence, characteristics, and outcomes is limited. Further research is needed to provide a better understanding of modifiable predictors of survival and functional decline in this population.
