ObjectivesTo assess the association between optimal end-stage renal disease (ESRD) starts and clinical and utilization outcomes in an integrated healthcare delivery system.Study DesignRetrospective observational cohort study in 6 regions of an integrated healthcare delivery system, 2011-2013.MethodsPropensity score techniques were used to match 1826 patients who experienced an optimal start of renal replacement therapy (initial therapy of hemodialysis via an arteriovenous fistula or graft, peritoneal dialysis, or pre-emptive transplant) to 1826 patients who experienced a nonoptimal start (hemodialysis via a central venous catheter). Outcomes included 12-month rates of sepsis, mortality, and utilization (inpatient stays, total inpatient days, emergency department visits, and outpatient visits to primary care and specialty care).ResultsOptimal starts were associated with a 65% reduction in sepsis (odds ratio, 0.35; 95% CI, 0.29-0.42) and a 56% reduction in 12-month mortality (hazard ratio, 0.44; 95% CI, 0.36-0.53). Optimal starts were also associated with lower utilization, except for nephrology visits. Large utilization differences were observed for total inpatient days (9.4 for optimal starts vs 27.5 for nonoptimal starts; relative rate [RR], 0.45; 95% CI, 0.38-0.52) and outpatient visits for specialty care other than nephrology or vascular surgery (12.5 vs 18.3, respectively; RR, 0.62; 95% CI, 0.53-0.74).ConclusionsCompared with patients with nonoptimal starts, patients with optimal ESRD starts have lower morbidity and mortality and less use of inpatient and outpatient care. Late-stage chronic kidney disease and ESRD care in an integrated system may be associated with greater benefits than those previously reported in the literature.
