SURVIVAL COX PROPORTIONAL HAZARD IN CHRONIC KIDNEY DISEASE WITH HEMODIALYSIS AT HAJI GENERAL HOSPITAL, SURABAYA
Background: Patients with chronic kidney disease should have dialysis therapy throughout their life (usually 1-3 times a week) or until they get a new kidney through a kidney transplant surgery to maintain the existing kidney function. A survival analysis was needed to determine the survival time of hemodialysis patients. The purpose of this study was to analyze the survival of hemodialysis patients with cox proportional hazard at Haji General Hospital, Surabaya.
Material and Method: This research was an observational analytic study with retrospective cohort design through CPH survival analysis. This study was conducted at Haji General Hospital, Surabaya, in Mei 2018. Samples were taken as many as 55 new hemodialysis patients, which registered in 2012. The data used was secondary data from 2012 until March 2018.
Result: The median survival estimate for hemodialysis patients was 581 days. In cox regression analysis simultaneously obtained sex (p=0.057), marital status (p=0.016), employment status (p=0.164), comorbidities (p=0.0001). In the further analysis of the cox regression partially obtained marital status (p=0.043), comorbidities (p=0.0001). Cox regression analysis model was obtained " h (t) = h0 (t) exp (0.638 marital status + 1.531 comorbidities)".
Conclusion: Cox regression analysis showed marital status and comorbidities had significant effect on survival of hemodialysis patient at RSU Haji Surabaya
