Background
We investigated whether implementation of the end-stage renal disease prospective payment system (ESRD PPS) was associated with changes in thrombolytic therapy use and other aspects of catheter management in hemodialysis (HD) patients.
Methods
Using quarterly, period prevalent cohorts of patients undergoing maintenance HD with a catheter in the US Renal Data System (2008–2015), we studied rates of claims for within- and outside-HD-unit thrombolytic use, and thrombus/fibrin sheath removal, and rates of delayed HD treatment after ESRD PPS implementation, January 1, 2011. Associations between PPS implementation and change in trend of rates of each outcome were assessed using covariate-adjusted Poisson regression, using a piecewise linear function for quarter-time (with breakpoint at PPS implementation).
Results
Among an average of 69,428 quarterly catheter users, rates of claims for within-HD-unit thrombolytic use declined from 236.6 (Q1–2008) to 81.4 (Q4–2012) per 100 person-years (P < 0.0001, PPS association with change in trend); rates of claims for thrombus/fibrin sheath removal procedures increased from 3.9 (Q1–2008) to 8.8 (Q3–2015) per 100 person-years (P = 0.0001, PPS association with change in trend). Rates of delayed HD treatment increased from 1.6 (Q2–2008) to 2.3 (Q3–2015) per patient-quarter, although PPS implementation was associated with a decrease in this rising trend (1.6% increase per quarter pre-PPS, 1.2% post-PPS; P < 0.0001, change in trend).
Conclusions
After PPS implementation, thrombolytic use decreased and thrombus/fibrin sheath removal increased. The increasing trend in delayed HD treatment appeared to slow after PPS implementation, but delayed sessions continued to increase year over year for unclear reasons.
