Aims : Identifying and modifying factors such as inadequate dialysis and consequently disability and mortality that may influence hemodialysis patients' quality of life can cause more appropriate level of health in these patients. This study is done with the aim of "determining relationship of quality of life with dialysis adequacy and laboratory parameters in hemodialysis patients".

  Methods: In this cross-sectional study, 99 hemodialysis patients were investigated through convenient sampling in 2013. The tools of the study included: quality of life questionnaire specialized to dialysis patients, KT/V for determining dialysis adequacy and albumin, Hemoglobin, Fasting Blood Sugar (FBS), creatinine, Bilirubin, Potassium, Sodium , Calcium and Phosphorus laboratory parameters. After collecting data, the relationship between them was determined. SPSS16 software, Pearson correlation and ANOVA statistical tests were used for data analysis.

  Results : quality of life and dialysis adequacy of the subjects of the study were not in an appropriate level. There was a significant difference (p<0.05) between quality of life and dialysis adequacy. Also there was a significant statistical correlation between the score of quality of life and albumin, hemoglobin , bilirubin, creatinine, potassium, calcium and phosphorus parameters (p<0.05). But there was no significant correlation between FBS and Sodium with the score of quality of life.

  Conclusion : more appropriate level of quality of life can be achieved for these patients through planning and implementing nursing interventions regarding increase of dialysis adequacy and improvement of some parameters.
