Abstract
OBJECTIVE: Since 2007, the use of erythropoiesis-stimulating agents (ESAs) to treat anemia in cancer patients receiving chemotherapy has been increasingly restricted in the USA. This study assessed hemoglobin (Hb) decline over time among chemotherapy patients. METHODS: Episodes of chemotherapy care were identified in a large US-oncology electronic medical record database; weekly Hb levels were computed in the first 8 weeks. Unadjusted and adjusted proportions of patient-weeks with Hb decline > 1 g/dl (i.e. representing clinically significant decline) within 1 or 2 weeks were analyzed. RESULTS: Between 2006 and 2009, unadjusted proportions of patient-weeks with Hb decline > 1 g/dl increased (1-week, from 12.7% to 14.9%; 2-week, from 19.3% to 26.3%). Adjusted 1-week proportions in 2007 were similar to 2006, but increased in 2008 (odds ratio [OR] 1.135; 95% confidence intervals [CI] 1.067, 1.208) and in 2009 (OR 1.235; 95% CI 1.094, 1.395). Adjusted 2-week proportions had the same pattern. CONCLUSIONS: Since restrictions on ESA use were introduced in the USA, more patients have experienced a clinically significant Hb decline after chemotherapy initiation. Initiating anemia therapy at the earliest indicated opportunity may help reduce the risk of such declines.
