Frailty in hemodialysis patients: results of a screening program and multidisciplinary interventions

Background

The number of frail patients of advanced age with end-stage kidney disease (ESKD) undergoing hemodialysis is increasing globally. Here we evaluated a frailty screening program of ESKD patients starting hemodialysis, and subsequent multidisciplinary interventions.

Methods

This was a prospective observational study of ESKD patients in a hemodialysis program. Patients were evaluated for frailty (Fried frail phenotype) before and after a 12-month period. Patients followed standard clinical practice at our hospital, which included assessment and multidisciplinary interventions for nutritional (malnutrition-inflammation score, protein-energy wasting), physical [short physical performance battery (SPPB)] and psychological status.

Results

A total of 167 patients (mean ± standard deviation age 67.8 ± 15.4 years) were screened for frailty, and 108 completed the program. At screening, 27.9% of the patients were frail, 40.0% pre-frail and 32.1% non-frail. Nutritional interventions (enrichment, oral nutritional supplements, intradialytic parenteral nutrition) resulted in stable nutritional status for most frail and pre-frail patients after 12 months. Patients following recommendations for intradialytic, home-based or combined physical exercise presented improved or stable in SPPB scores after 12 months, compared with those that did not follow recommendations, especially in the frail and pre-frail population (P = .025). A rate of 0.05 falls/patient/year was observed. More than 60% of frail patients presented high scores of sadness and anxiety.

Conclusions

Frailty screening, together with coordinated interventions by nutritionists, physiotherapists, psychologists and nurses, preserved the health status of ESKD patients starting hemodialysis. Frailty assessment helped in advising patients on individual nutritional, physical or psychological needs.

Impact and safety outcomes of an intradialytic physical exercise program

INTRODUCTION

Patients undergoing hemodialysis (HD) are characterized by a poor physical condition and a substantial sedentary profile. The implementation of physical exercise programs in the hemodialysis units is usually limited by the inherent safeness and the lack of appropriate resources.

OBJECTIVES

We aimed to evaluate the impact and safety outcomes of the implementation of an intradialytic physical exercise program (IPE) by a multidisciplinary team (physiotherapist and nursing assistant) in the physical condition of the patients.

MATERIAL AND METHODS

This six months single-centre and experimental pre-post prospective study was carried out in 34 patients. A two day-week combined IPE intervention was implemented. The cardiopulmonary capacity (6MWT), muscular strength (HG, leg dynamometry and 10STS), body composition (bioimpedance) and coordination capacity (Timed Up and Go test) was assessed at the beginning and at the end of the study. Safety was evaluated by means of the number of issues regarding the vascular access, the hemodynamic stability as well as the vascular refilling profile (RBV) in each session. The adhesion to the program was also registered. Additionally, analytical parameters were recorded.

RESULTS

The adhesion to an IPE program was high (70.8%). A significant improvement of the cardiopulmonary capacity (6MWT average increase 47 m; p < 0.001), superior limbs (HG average increase of 1.6 kg; p = 0.007) as well as the lower extremities (10STS; p = 0.003; dynamometry p < 0.05). Regarding safeness, there were no incidences neither significant difference in the RBV.

CONCLUSIONS

A combined IPE may contribute to the improvement of the physical condition of the patients as well as ensures a safe development of the HD treatment. We suggest a multidisciplinary team in order to efficiently establish an IPE program.
