| Popis: | Patients receiving long-term hemodialysis have a yearly mortality rate of 15% to 20%.To determine whether attaining clinical performance measures for hemodialysis care is associated with favorable 12-month mortality and hospitalization rates.Cohort study.Outpatient hemodialysis centers in the United States.15 287 patients who were selected from a 5% random sample of patients receiving long-term hemodialysis.The authors used data from the Centers for MedicareMedicaid Services End-Stage Renal Disease Clinical Performance Measures Project from 1999 and 2000. The clinical performance measure targets were hemoglobin value of 110 g/L or greater; serum albumin value of 40 g/L or greater or 37 g/L or greater (bromcresol green and bromcresol purple laboratory methods, respectively); use of a fistula for vascular access; and measured single-pool Kt/V urea value of 1.2 or greater. The outcome measures were death or hospitalization during 1-year follow-up.8364 patients (54.7%) were hospitalized and 3062 (20.0%) died during the 12-month follow-up period. Six percent of patients did not meet any clinical measure targets, 24% met 1 target, 39% met 2 targets, 24% met 3 targets, and 7% met all 4 targets. The unadjusted 12-month hospitalization and mortality rates for these 5 groups were 60%, 60%, 56%, 49%, and 43% (P0.001) and 29%, 25%, 21%, 14%, and 7% (P0.001), respectively. The risk for death increased for each additional guideline indicator that was not met: Adjusted hazard ratios were 4.6 (95% CI, 3.3 to 6.4), 3.5 (CI, 2.6 to 4.7), 2.6 (CI, 1.9 to 3.5), and 1.9 (CI, 1.4 to 2.6) for 0, 1, 2, or 3 targets met, respectively, compared with meeting 4 targets (referent). Similarly, the risk for hospitalization increased for each additional guideline indicator that was not met: Adjusted hazard ratios were 1.6 (CI, 1.4 to 1.9), 1.5 (CI, 1.3 to 1.7), 1.3 (CI, 1.1 to 1.5), and 1.1 (CI, 0.98 to 1.3), respectively.It was not possible to determine the roles of severity of illness, other patient factors, or suboptimal care in failure to meet performance measures.In patients receiving long-term hemodialysis, meeting multiple clinical measure targets is associated with a decrease in hospitalization and mortality rates. |
