Abstract
Background: Since hemodialysis (HD) patients are prone to various complications and high mortality, they need to be treated in HD units with professional personnel, proper equipment, and facilities. The Korean Society of Nephrology has been conducting an HD unit accreditation program since 2016. This study was performed to evaluate whether a qualified dialysis center (QDC) reduced the mortality of HD patients.
Methods: This longitudinal, observational cohort study included 31,227 HD from 832 facilities. HD units were classified into two groups: the hospitals that have been certified as QDC between 2016 and 2018 (n = 219) and hospitals that have never been certified as QDC (non-QDC, n = 613). Baseline characteristics and patient mortality were compared between QDC vs. non-QDC groups using Korean HD quality assessment data from 2018. Multivariate logistic regression and the Cox proportional hazards model were used to compare patient mortality between the two groups.
Results: Among study subjects, 30.6% of patients were treated at QDC and 69.4% were treated at non-QDC. The patients in the QDC were younger and had a longer dialysis duration, lower serum phosphorus and calcium levels, and higher hemoglobin and single-pool Kt/V levels compared to the patients from the non-QDC group. After adjusting for demographic and clinical parameters, QCD independently reduced mortality risk (hazard ratio, 0.897; 95% confidence interval, 0.847-0.950; p < 0.001).
Conclusion: The HD unit accreditation program may reduce the risk of death among patients undergoing HD.
期刊介绍：
Kidney Research and Clinical Practice (formerly The Korean Journal of Nephrology; ISSN 1975-9460, launched in 1982), the official journal of the Korean Society of Nephrology, is an international, peer-reviewed journal published in English. Its ISO abbreviation is Kidney Res Clin Pract. To provide an efficient venue for dissemination of knowledge and discussion of topics related to basic renal science and clinical practice, the journal offers open access (free submission and free access) and considers articles on all aspects of clinical nephrology and hypertension as well as related molecular genetics, anatomy, pathology, physiology, pharmacology, and immunology. In particular, the journal focuses on translational renal research that helps bridging laboratory discovery with the diagnosis and treatment of human kidney disease. Topics covered include basic science with possible clinical applicability and papers on the pathophysiological basis of disease processes of the kidney. Original researches from areas of intervention nephrology or dialysis access are also welcomed. Major article types considered for publication include original research and reviews on current topics of interest. Accepted manuscripts are granted free online open-access immediately after publication, which permits its users to read, download, copy, distribute, print, search, or link to the full texts of its articles to facilitate access to a broad readership. Circulation number of print copies is 1,600.
