Abstract: | OBJECTIVE: To examine whether the frequency of physician contact is associated with accepted quality of care measures reflecting clinical performance in chronic kidney disease patients. DESIGN: Prospective cohort study of end-stage renal disease patients begun in 1995, followed for 2.5 years. SETTING: 76 not-for-profit US dialysis clinics. STUDY PARTICIPANTS: 678 incident hemodialysis patients for whom we had information on average frequency of patient-physician contact at each clinic (low, monthly or less frequent; intermediate, between monthly and weekly; high, more than weekly), determined by clinic survey. MAIN OUTCOME MEASURES: Achievement of accepted 6 month clinical performance targets of albumin (> or =3.5 g/dl), calcium-phosphate (Ca-P) product (<60 mg(2)/dl(2)), dialysis dose (Kt/V > or = 1.2), vascular access type (fistula), and hemoglobin (> or =11 g/dl). RESULTS: By logistic regression, patients treated at clinics reporting less frequent physician contact had lower odds of achieving most targets, statistically significantly for albumin low, adjusted odds ratio (OR) = 0.83, 95% confidence interval (CI), 0.55-1.25; intermediate, adjusted OR = 0.62, 95% CI, 0.42-0.93; reference, high] and dialysis dose (low, adjusted OR = 0.26, 95% CI, 0.08-0.89; intermediate, adjusted OR = 0.67, 95% CI, 0.20-2.27); however, they had greater odds of achieving the hemoglobin target (low, adjusted OR = 1.94, 95% CI, 1.24-3.04; intermediate, adjusted OR = 1.89, 95% CI, 1.27-2.83). Additionally, the number of targets reached was statistically significantly lower in the monthly or less group (adjusted OR = 0.43, 95% CI, 0.20-0.94). CONCLUSIONS: More frequent patient-physician contact is positively associated with the achievement of clinical performance targets in chronic kidney disease care. |
