Comparative Study
Improving the care of patients treated with hemodialysis: a report from the Health Care Financing Administration's ESRD Core Indicators Project.
To determine the impact of a quality improvement intervention on dialysis care delivered to hemodialysis patients, we studied 213 hemodialysis facilities in North Carolina, South Carolina, and Georgia. Dialysis adequacy measurements made on two random samples of 30 patients per treatment center, or all patients if fewer than 30 were treated, selected in October 1994 (preintervention) and October 1995 (postintervention) were used to estimate the facility mean urea reduction ratio (URR) and the proportion of patients with a mean URR less than 50%. The 10% of facilities (n = 22) with the highest proportion of patients with a mean URR less than 50% in the facility at preintervention were selected for an intervention that included feedback of facility-specific mean URR, educational programs, a quality improvement workshop, and monitoring until improvement was attained. ⋯ Comparable reductions in the proportion of patients with a mean URR of less than 60% were 16.2% in intervention centers and 2.0% in comparison facilities (P < 0.001). After controlling for facility case mix and other characteristics, the intervention was independently associated with an absolute 2.4% increase in facility-specific mean URR. We conclude that the intervention was associated with improvement in hemodialysis care.
