“…With a continuous method as the UV absorbance spent dialyzate monitoring, the immediate recognition of low clearances can trigger prompt interventions correcting or mitigating possible issues arising during treatment. 40 It can be applied not only in double but also in single needle hemodialysis as opposed to the ionic dialysance method. 41 This study has strengths and limitations.…”

Introduction: Patients’ session-to-session variation has been shown to influence outcomes, making critical the monitoring of dialysis dose in each session. The aim of this study was to detect the intra-patient variability of blood single pool Kt/V as measured from pre-post dialysis blood urea and from the online tool Adimea®, which measures the ultraviolet absorbance of spent dialyzate. Methods: This open, one-armed, prospective non-interventional study, evaluates patients on bicarbonate hemodialysis or/and on hemodiafiltration. Dialysis was performed with B. Braun Dialog+ machines equipped with Adimea®. In the course of the prospective observation, online monitoring with Adimea® in each session was established without the target warning function being activated. A sample size of 97 patients was estimated. Results: A total of 120 patients were enrolled in six centers in China (mean age 51.5 ± 12.2 years, 86.7% males, 24.2% diabetics). All had an AV-fistula. The proportion of patients with blood Kt/V < 1.20 at baseline was 48.3%. During follow-up with Adimea®, the subgroup with Kt/V > 1.20 at baseline remains at the same adequacy level for more than 90% of the patients. Those with a Kt/V < 1.20 at baseline, showed a significant increase of Kt/V to 60% of the patients reaching the adequacy level >1.20. The coefficient of variation for spKt/V as evaluated by Adimea® was 9.6 ± 3.4%, not significantly different from the 9.6 ± 8.6% as blood Kt/V taken at the same time. Conclusion: Online monitoring of dialysis dose by Adimea® improves and maintains dialysis adequacy. Implementing online monitoring by Adimea into daily practice moves the quality of dialysis patient care a significant step forward.
