Practice Patterns and Adequacy of Maintenance Hemodialysis in Rio Grande, RS, Brazil

摘要

Introduction: Hemodialysis is the most common end-stage renal disease treatment worldwide. Several factors may influence treatment outcomes. Adequacy (dose) of hemodialysis remains controversial; however, investigations on the effectiveness rate (Kt/V ≥ 1.2), which could reflect morbimortality, are preferred. Objective: This study aimed to describe the level of adequacy of hemodialysis among patients undergoing treatment in the city of Rio Grande (RS), Brazil. Method: In this prospective cohort study, 156 patients undergoing hemodialysis treatment between July 2016 and June 2017 in the two hemodialysis centers in the city of Rio Grande (RS), Brazil, were included. Frequency distribution as per Kt/V stratification was analyzed. Chi-square test was used to compare proportions. Results: Adequate hemodialysis (Kt/V ≥ 1.2) was observed in 105 patients (67%), 88% were from the municipality (mean age, 59 years), and 43% had visited the hospital before knowing about their kidney disease. Most of them were referred to a nephrologist (70%). Of the 156 patients, 114 patients (73%) remained in dialysis treatment, 10 (6%) underwent transplantation, 9 (6%) were transferred, and 23 (15%) died at the end of 12 months. Conclusion: Primary care should be expanded for early diagnosis of chronic kidney disease, improved venous access preparation, and increased number of patients with hemodialysis adequacy. Hemodialysis adequacy in patients undergoing treatment in the city of Rio Grande (RS), Brazil, needs to be improved.
