Background
While BB have demonstrated benefit in CHF, there is uncertainty among HD pts. Comparative BB outcomes (beta selective, dialyzability, lipophilic) in the ESRD transition period are lacking; while studies on newly initiated BB after ESRD are conflicting and overall sparse. Among CHF patients on BB at ESRD transition, we evaluated BB use patterns and 1-year mortality.
Methods
A retrospective cohort study (1/1/2007-6/30/2016) within Kaiser Permanente Southern California (an integrated health system) of CKD patients with CHF who transitioned to HD while on BB. BB use and type [dialyzable (D) vs non dialyzable (ND)] were evaluated. Multivariable regressions were used to estimate 1-year mortality HR based on post ESRD transition BB use and type.
Results
A total of 2756 pts w CHF on BB transitioned to HD (age 68 yrs, 57% males, 31% whites, 23% blacks, and 34% Hispanics). Within 120 days post transition, 25% of pts discontinued BB, 38% were on D BB, and 24% were on ND BB. Post ESRD transition, 6.5% switched their BB dialyzable types (similar both directions). Mean blood pressure w/in 120days post transition was 130/65mmHg but lowest among ND BB pts. Mortality rates were 126.5 (per 1000 person-yrs), 205.7, and 223.2 for D BB, ND BB, and pts off BB, respectively. 1-yr mortality HR’s were 1.37 (1.07-1.74) and 1.66 (1.32-2.09) for ND BB and off BB compared to D BB pts. Carvedilol (ND) pts had a mortality HR of 1.32 (1.00-1.73) vs metoprolol (D).
Conclusion
Among CHF pts on BB who transitioned to HD, 25% discontinued BB while 6.5% switched BB dialyzability types. The highest short-term mortality were observed in pts off BB followed by ND BB compared to D BB. Given the vulnerable state of ESRD transition and the high-risk CHF ESRD population, BB use may be an area of focus to help improve ESRD transition outcomes.
