Potentially avoidable hospitalizations in older patients with acute myeloid leukemia (AML).
206 Background: Many older adults ( ≥ 60) with AML have a poor prognosis and spend a significant portion of their life from diagnosis until death in the hospital. We examined the reasons for hospitalizations and identified potentially avoidable hospitalizations. Methods: We conducted a retrospective analysis of 200 patients ( ≥ 60) diagnosed with AML between 1/1/2006 and 10/30/2011 at two hospitals in Boston to examine the reasons for hospitalizations during treatment. Practicing physicians used a consensus-driven medical record review process to identify primary reason for each hospitalization and categorize it as “potentially avoidable” or “not avoidable” based on a novel adaptation of the Graham’s criteria for potentially avoidable hospital admissions. We compared the rate of potentially avoidable hospitalization between older patients receiving intensive chemotherapy (n = 124) versus non-intensive chemotherapy (n = 76) using Fisher’s Exact test. Results: We evaluated 627 hospitalizations after the diagnosis of AML in 200 unique patients. The median age was 69 years [range 60-90] and the median number of hospitalizations was 4.0 [range 0-18]. 33.2% of patients underwent stem cell transplantation. The most common primary reasons for hospitalizations were: fever/infection (38.3%), planned hospitalizations for chemotherapy or transplantation (35.9%), and uncontrolled symptoms (10.5%). We identified 108/627 hospitalizations (17.2%) as potentially avoidable. Among potentially avoidable hospitalizations, 40.7% were due to premature hospital discharge, 22.2% could have been managed in the outpatient setting, 13.9% failed to have timely outpatient follow-up, and 13% were due to patients’ medication non-adherence. There were no differences in potentially avoidable hospitalizations between patients receiving intensive vs. non-intensive chemotherapy (16.9% vs. 17.8%, P = 0.83). Conclusions: Most hospitalizations in older patients with AML are unavoidable and driven by the illness course and its treatments. However, a minority of hospitalizations is potentially avoidable and should be the focus of future interventions to reduce health care utilization and the burden of AML on this population.
