Prognostic stratification in older adults commencing dialysis.
Prognostic stratification in older adults commencing dialysis. journals of gerontology. Series A, Biological sciences and medical sciences Cheung, K. L., Montez-Rath, M. E., Chertow, G. M., Winkelmayer, W. C., Periyakoil, V. S., Kurella Tamura, M. 2014; 69 (8): 1033-1039Abstract
Accurate prognostic models could inform treatment decisions for older adults with end-stage renal disease who are considering dialysis and might identify patients more appropriate for conservative care or hospice.In a cohort of patients aged =67 years commencing dialysis in the United States between January 1, 2008 and June 30, 2009, we compared the discrimination of three existing instruments (the Liu index; the French Renal Epidemiology and Information Network score; and hospice eligibility criteria) for the prediction of 6-month mortality. We estimated the odds of death associated with each prognostic index using logistic regression with and without adjustment for age. Predictive indices were compared using the concordance ("c")-statistic.Of 44,109 eligible patients, 10,289 (23.3%) died within 6 months of dialysis initiation. The c-statistic for the Liu, Renal Epidemiology and Information Network, hospice eligibility criteria, and combined Liu/hospice eligibility criteria scores without and with age were 0.62/0.65, 0.63/0.66, 0.65/0.68, and 0.68/0.70, respectively. Discrimination was poorer at older ages, especially for the Liu and Renal Epidemiology and Information Network scores. Although sensitivity was poor, a Renal Epidemiology and Information Network score =9 or an hospice eligibility criteria =3 had relatively high specificity.Existing prognostic indices based on administrative data perform poorly with respect to prediction of 6-month mortality in older patients with end-stage renal disease commencing dialysis.
