<i>Background:</i> Hemodialysis (HD) patients have high hospitalization rates. This nonrandomized trial tested the effect of a bundle of renal-specific “Right TraC™” strategies on 30-day all-cause readmission rates and, secondarily, 90-day readmissions and overall admissions among HD patients. <i>Methods:</i> Twenty-six Fresenius clinics in West Virginia, Ohio, and Kentucky participated in the interventions. Eighteen matched clinics served as controls; intervention clinics also served as their own controls. We deployed the intervention in 3 incremental phases focused on patient information exchange, post-hospital follow-up, and telephonic case management. Thirty-day hospital readmissions per patient year (ppy) were calculated by dividing the total number of readmissions within 30 days of index admission by the total number of patient-years in baseline (2012) and remeasurement (2014) periods. We also compared readmission rates from 2010 to 2015. We used repeated measures Poisson regression to compare outcomes between groups and time periods. <i>Results:</i> From 2012 to 2014, 30-day all-cause readmissions ppy declined for Right TraC clinics (from 0.88 to 0.66 [<i>p</i> < 0.001]; for controls, from 0.73 to 0.61 [<i>p</i> = 0.16]). Difference in change between groups was nonsignificant (<i>p</i> = 0.26). Overall admissions ppy declined: for Right TraC clinics from 2.51 to 1.97 (<i>p</i> < 0.001); for controls from 2.14 to1.92 (<i>p</i> = 0.21); difference in change between groups was significant (<i>p</i> = 0.01). For 2010, 2011, and 2012, Right TraC clinic 30-day readmissions ppy were unchanged: 0.89, 1.00, 0.88 (<i>p</i> = 0.61 and <i>p</i> = 0.49); they declined to 0.66 (<i>p</i> < 0.001) in 2014 (intervention year); rose to 0.70 (<i>p</i> = 0.06) in 2015 (interventions discontinued). <i>Conclusion:</i> We conclude that Right TraC interventions may have been helpful in reducing hospital readmission rates.
