Abstract
Background
Hemodialysis usually lasts until the end of life or until kidney transplantation.
Objective
to verify the factors related to clinical outcomes and survival of chronic renal patients in hemodialysis at a clinic in the south of Santa Catarina
Method
A retrospective cohort study. Survival was assessed by Kaplan-Meier curves and outcome-related factors were assessed using Cox regression, with comparisons using Hazard Ratio (HR) and 95% confidence intervals.
Results
Among the 120 patients, the mean age was 61.8 (± 13.9) years. The main sector of referral for hemodialysis was the nephrologist (33.3%). The main underlying diseases identified were hypertension (60.8%) and Diabetes Mellitus (29.2%). Death was recorded in 44.2% of the patients, and seven (5.8%) performed a transplant. Survival decreased from 76.1% in one month to 49.3% in one year of treatment. Referral by intensive care unit (HR 18.1 95% CI 4.49-72.8) and Basic Health Unit (HR 9.27 95% CI 1.48-58.2) were associated with death, besides of higher values of initial calcium (HR 2.36 95%CI 1.21-4.62) and lower final creatinine (HR 0.69 95%CI 0.55-0.87).
Conclusion
The main outcome was death, being the patient´s survival, evaluated in a short term, lower than expected, suggesting late referral to the substitutive treatment.
