Practice patterns and outcomes for adults with acute myeloid leukemia receiving care in community vs academic settings

Abstract

Consistent with observations in other disease settings, retrospective studies have indicated that treatment outcomes for adults with acute myeloid leukemia (AML) are better in higher- vs lower-volume hospitals and academic vs nonacademic centers, with greatest benefits noted in acute promyelocytic leukemia. Younger age, more frequent receipt of chemotherapy and hematopoietic cell transplantation, and differences in comorbidities and socioeconomic factors may partially account for these differences. With new therapeutic options including oral small molecule inhibitors and parenteral drugs suitable for outpatient administration, there is increasing interest from patients and physicians in treating AML in the community setting and avoiding referral to academic centers. This may be particularly true for older adults, for whom treatment rates in the community have historically been low, and for those with comorbidities, because treatment benefits are estimated to be low, and thus travel to academic centers is perceived as especially burdensome. How the volume-outcome relationship is affected by the shift of the treatment landscape in AML over the last few years is unknown. Additionally, improvements in supportive care (transfusion support, broad-spectrum oral antimicrobials), resulting in gradually decreasing early death rates over time, and the growing focus on the impact of AML therapy on quality of life and treatment cost concerns further fuel the larger trend toward an increasing proportion of care delivered in the outpatient setting. Here, we examine whether the current shift of administering chemotherapy and supportive care to the outpatient setting can be translated to the community setting without compromising patient outcomes.
