Introduction: Labeling a patient as "frail" may be useful in assessing the prognosis and therapeutic approach.
Objective: The aim of the study is to define a pattern of frailty among our dialysis population, to analyse the incidence and clinical evolution of these patients.
Materials and methods: We analysed a total of 320 patients with stage V chronic kidney disease (CKD) who were on hemodialysis between September 2014 and September 2015. To define a patient as frail we used the Fried phenotype model, and we added a new criteria-dialysis session length longer than 12 hours/week.
Results: 5.6% of the 320 patients were frail. We found statistically significant differences regarding body mass index (BMI), hemoglobin (Hgb), and serum albumin, as well as the ability to perform the basic activities of daily living (p < 0.005), ability to ambulate (p = 0.01) and perform transfers (p < 0.005). We found statistically significant differences between the two groups in terms of hospital admissions (p = 0.005) and mortality (p < 0.005).
Conclusion: 5.6% of the study population were frail, with lower BMI, serum albumin and hemoglobin, lower capacity for basic activities of daily living, ambulation, and transference, as well as higher morbidity and mortality.
