The rate of SA-BSIs in pts who start in-center HD with a CVC is estimated to be ~1 cases per 100-person months (PMID: 28663227), with higher rates observed in CVC-HD pts with SA-NC and DM. This study estimated the yearly outcomes and costs attributable to CVC-related SA-BSIs in adult CVC-HD pts with SA-NC and DM who start in-center HD.


A probabilistic model from the US Healthcare Perspective (1-year time horizon) was developed. The study population consisted of ~45,000 pts with DM as primary cause of ESRD who start in-center CVC-HD each year. Markov modeling (4 12-week cycles) was used to simulate the transitions between the different health-related dynamic states of CVC-HD pts with SA-NC and DM and estimate the yearly CVC-related SA-BSI-related outcomes and costs. Time on CVC, prevalence of SA-NC, CVC-related SA-BSI rates, CVC-related SA-BSI re-infection rates, 12-week SA-BSI costs (first episode and re-infections), and CVC-related SA-BSI death rates were identified in comprehensive literature review (Figure 1).


Data indicate that 18,000 of the 45,000 annual incident CVC-HD pts with DM have SA-NC. Among CVC-HD pts with SA-NC and DM, the model estimates that there are 3,690 CVC-related SA-BSIs, 720 SA-BSI-related re-infections, and 900 SA-BSI-related deaths annually. Attributable yearly mean (SD) costs are projected to be 229 (51) million USD.


The estimated annual incidence of CVC-related SA-BSIs in CVC-HD pts with DM who start in-center HD that is attributable to SA-NC is high, resulting in considerable morbidity, mortality, and healthcare costs. New technologies are needed to prevent CVC-related SA-BSIs in this population.
