Survival and quality of life in elderly patients in conservative management

Dependency and frailty in the older haemodialysis patient

BACKGROUND

Frailty among older adults undergoing hemodialysis is increasingly prevalent, significantly impacting cognitive function, mobility, and social engagement. This study focuses on the clinical profiles of very older adults in hemodialysis, particularly examining the interplay of dependency and frailty, and their influence on dialysis regimens.

METHODS

In this observational, descriptive study, 107 patients aged over 75 from four outpatient centers and one hospital unit were examined over a year. Patient data encompassed sociodemographic factors, dialysis specifics, analytical outcomes, lifestyle elements, and self-reported post-treatment fatigue. Malnutrition-inflammation scale was used to measure the Nutritional status; MIS scale for malnutrition-inflammation, Barthel index for dependency, Charlson comorbidity index; FRIED scale for frailty and the SF12 quality of life measure.

RESULTS

The study unveiled that a substantial number of older adults on hemodialysis faced malnutrition (55%), dependency (21%), frailty (46%), and diminished quality of life (57%). Patients with dependency were distinctively marked by higher comorbidity, severe malnutrition, enhanced frailty, nursing home residency, dependency on ambulance transportation, and significantly limited mobility, with 77% unable to walk. Notably, 56% of participants experienced considerable post-dialysis fatigue, correlating with higher comorbidity, increased dependency, and poorer quality of life. Despite varying clinical conditions, dialysis patterns were consistent across the patient cohort.

CONCLUSIONS

The older adult cohort, averaging over four years on hemodialysis, exhibited high rates of comorbidity, frailty, and dependency, necessitating substantial support in transport and living arrangements. A third of these patients lacked residual urine output, yet their dialysis regimen mirrored those with preserved output. The study underscores the imperative for tailored therapeutic strategies to mitigate dependency, preserve residual renal function, and alleviate post-dialysis fatigue, ultimately enhancing the physical quality of life for these patients.

Análisis del tratamiento conservador en el paciente con enfermedad renal crónica terminal. Revisión sistemática

Introducción: Desde hace unos años, debido a la inclusión de pacientes con enfermedad renal crónica cada vez más mayores en tratamiento renal sustitutivo, se viene ofreciendo como otra opción, tratamiento renal conservador, con resultados similares en algunas series al tratamiento dialítico.Objetivo: Revisar la literatura científica existente sobre el tratamiento renal conservador en pacientes con enfermedad renal crónica, su supervivencia y calidad de vida.Metodología: Se ha llevado a cabo una revisión sistemática. Se realizó una búsqueda en las bases de datos PubMed, ProQuest, Scielo y Scopus. Se incluyeron artículos científicos en español e inglés, y texto completo disponible. Se analizaron aquellos artículos que trataban sobre pacientes renales en estadío final de la enfermedad renal crónica terminal, tratados con tratamiento paliativo únicamente o en comparación con el tratamiento renal sustitutivo.Resultados: Se han incluido 15 artículos publicados entre los años 2010 y 2020. La enfermedad renal crónica es un problema de alta prevalencia en nuestra población, lo cual condiciona los tratamientos sustitutivos de la función renal. El tratamiento renal conservador surge como opción al sustitutivo, en aquellos pacientes mayores o con una corta expectativa de vida. Como factores más importantes a tener en cuenta surgen la supervivencia y la calidad de vida.Conclusiones: En el paciente con enfermedad renal crónica en tratamiento renal sustitutivo la supervivencia es mayor, aunque con peor calidad de vida, mientras que en el caso del tratamiento renal conservador suele ser al contrario. En pacientes mayores de 75-80 años la supervivencia se iguala, siendo necesario potenciar la calidad de vida y paliar los síntomas de la enfermedad

Clasificación funcional del paciente anciano en hemodiálisis y su influencia en la individualización del tratamiento

Introducción: La edad de los pacientes en hemodiálisis está aumentando, presentando mayor deterioro. Objetivos: Conocer la situación del paciente ancia­no en hemodiálisis categorizando nuestra población. Ana­lizar la relación entre las escalas de funcio­nalidad, desnutrición y comorbilidad. Material y Método: Estudio descriptivo transversal, pacien­tes 75-95 años. Se midieron: a) Comorbilidad-CHARLSON: alta (>6 puntos). b) Nutrición-MISS: extremadamente des­nutrido (<10 puntos.); desnutrición muy severa (>7-10 puntos); moderada-severa (>5-7 puntos); leve-moderada (>2-5 puntos); normonutrido (<2 puntos); c) Dependencia-BAR­THEL, independiente (100 puntos); dependencia leve (91-99 puntos); moderada (61-90 puntos.); severa (21-60 puntos.); total (<20 puntos). d) Fragilidad-FRAIL, no fragilidad (0 puntos); prefrágil (1-2 puntos); frágil (>3 puntos). Resultados: 60 pacientes, 68%(41) hom­bres, edad media 81,85±5,58 años y tiempo HD 49,88±40,29 meses. Etiología más prevalente, diabe­tes mellitus (28%). MIS: 6,01±3,80 puntos. clasificándose 8(13%) normonu­tridos, 24(40%) desnutrición leve-moderada, 10(17%) desnutrición moderada-severa, 13(22%) desnutrición muy severa y 5(8%) extremadamente desnutridos. BARTHEL: 88,16±18,59 puntos, clasificó 32(53%) independientes, 6(10%) dependencia leve, 17(28%) dependencia modera­da, 4(7%) dependencia severa, 1(2%) dependencia total. FRAIL: 1,98±1,32 puntos, clasificó 10(17%) no frágiles, 31(51%) prefrágiles y 19(32%) frágiles. CHARLSON: 10,01±2,20 puntos. Presentando 60(100%) alta comorbilidad. CHARLSON presentó diferencias entre sexo, mayor en hombres (p=0,002). Se encontró alta correlación entre Barthel y Frail (r=0,647,p<0,001), moderada entre MIS y Barthel (r=0,556, p<0,001) y MIS y Frail (r=0,455,p<0,001). Charlson obtuvo peor correlación. Conclusiones: Se evidenció gran deterioro ge­neral del paciente añoso en diálisis, alertando sobre la nece­sidad de realizar tratamientos individualizados enfocados en su recuperación, incluida la propia diálisis.

Health-related quality of life associated with risk of death in Brazilian dialysis patients: an eight-year cohort

PURPOSE

Despite the advancements in renal replacement therapy, patients with end-stage renal disease face several limitations, with significant impacts on health-related quality of life (HRQoL) and mortality. This study aims to examine associations between quality of life and risk of death in Brazilian patients who underwent dialysis therapy between 2007 and 2015.

METHODS

Observational, prospective, non-concurrent cohort study of patients who underwent dialysis therapy at the Brazilian Public Health System (SUS) and were followed up for 8 years. Semi-structured questionnaires interrogating socioeconomic and demographic characteristics, as well as HRQoL measures (36 Item Short-Form Health Survey, SF-36), were employed. The Cox proportional risk model was used to investigate associations between HRQoL and risk of death.

RESULTS

Our sample comprised 1162 patients; of these, 884 were on hemodialysis (HD) and 278 on peritoneal dialysis (PD). Among the HD patients, death was associated with the physical (HR: 0.993; 95% CI: 0.989-0.997) and physical summary component (HR: 0.994; 95% CI: 0.989-0.999) domains of HRQoL. Regarding the PD patients, death was associated with the bodily pain (HR: 0.994; 95% CI: 0.990-0.998), mental health (HR: 0.094; 95% CI: 0.990-0.998), emotional problems (HR: 0.993; 95% CI: 0.987-0.998), social functioning (HR: 1.012; 95% CI: 1.002-1.023), physical problems (HR: 0.992; 95% CI: 0.986-0.998) and mental summary component (HR: 0.989; 95% CI: 0.981-0.997) domains of HRQoL.

CONCLUSIONS

Our data suggest that early and timely intervention measures aiming to enhance the HRQoL of dialysis patients are an essential component of professional practice and may contribute to improving the management of factors associated with dialysis patients' mortality.

Use of a Supportive Kidney Care Video Decision Aid in Older Patients: A Randomized Controlled Trial

BACKGROUND

There are few studies of patient-facing decision aids that include supportive kidney care as an option. We tested the efficacy of a video decision aid on knowledge of supportive kidney care among older patients with advanced CKD.

METHODS

Participants (age ≥ 65 years with advanced CKD) were randomized to receive verbal or video education. Primary outcome was knowledge of supportive kidney care (score range 0-3). Secondary outcomes included preference for supportive kidney care, and satisfaction and acceptability of the video.

RESULTS

Among all participants (n = 100), knowledge of supportive kidney care increased significantly after receiving education (p < 0.01); however, there was no difference between study arms (p = 0.68). There was no difference in preference for supportive kidney care between study arms (p = 0.49). In adjusted analyses, total health literacy score (aOR 1.08 [95% CI: 1.003-1.165]) and nephrologists' answer of "No" to the Surprise Question (aOR 4.87 [95% CI: 1.22-19.43]) were associated with preference for supportive kidney care. Most felt comfortable watching the video (96%), felt the content was helpful (96%), and would recommend the video to others (96%).

CONCLUSIONS

Among older patients with advanced CKD, we did not detect a significant difference between an educational verbal script and a video decision aid in improving knowledge of supportive kidney care or preferences. However, patients who received video education reported high satisfaction and acceptability ratings. Future research will determine the effectiveness of a supportive kidney care video decision aid on real-world patient outcomes.
