Estimating the Loss in Expectation of Life and Relative Survival Rate amongHemodialysis Patients in Iran

Background: information regarding the prognosis and burden of diseases can be used bypolicymakers to determine competing health priorities. we aimed to assess the relative survivalrate (rsr) and loss of expectation of life (lel) to evaluate the prognosis and burden of diseasesin hemodialysis (hd) patients.study design: a retrospective cohort study.methods: we recruited 648 hd patients referred to three referral centers in kerman city, iran, from2008 to 2019. rsr, was defined as the ratio of the observed and the expected survival rates ofgeneral population for persons of the same age and sex as patients in the current study. lel wasdetermined as the difference between corresponding life expectancies (le). the extended coxproportional hazard model was used to identify variables associated with the outcome.results: variables associated with outcome were diabetic status and age. in the 5th year of thefollow-up study, the overall rsr was 0.57. in general, for hd patients, the estimation of le andlel was 22.6 and 12.36 year, respectively.conclusion: hd patients, especially older patients, showed a very poor prognosis, with a largeamount of lost life expectancy. therefore, they need more care and attention from healthauthorities. it is suggested to estimate the cost of eliminating the risk factors causing kidneydiseases.
