title: Practice gaps and barriers to optimal care of hematologic malignancies in the United States.
abstract: BACKGROUND
  Treating patients with hematologic malignancies can be challenging for physicians because of the rapidly evolving standards of care and relatively low incidence of these diseases.
  
  
  OBJECTIVE
  To identify clinical challenges among hematologists and medical oncologists regarding the provision of care to patients with chronic myeloid leukemia (CML), acute lymphoblastic leukemia (ALL), or B-cell lymphomas. Methods Hematologists and medical oncologists in active practice in the United States and who have a case load of ≥ 1 patient a year with CML, ALL, or B-cell lymphoma were recruited. The initial qualitative phase consisted of an online case-based survey followed by an interview exploring the contextual and behavioral factors that influence treatment decisions (n = 27). The analysis of qualitative data then informed a quantitative phase, in which 121 participants completed an online survey composed of case vignettes, multiple choice, and semantic differential rating scale questions. The respondents' answers were compared with recommendations from treatment guidelines and faculty experts.
  
  
  RESULTS
  A higher frequency of bone marrow biopsies was reported compared with expert faculty recommendations by 74% of oncologists. Many respondents failed to recognize the clinical relevance of BCR-ABL mutations other than T315I. Respondents reported perceiving difficulties in individualizing treatment and interpreting response to treatment in patients with ALL and B-cell lymphomas. Fewer than 30% of respondents recognized the mechanisms of action of 5 of the 9 promising investigational agents presented.
  
  
  CONCLUSIONS
  Participant self-selection bias is a possibility because participation was voluntary. Practice gaps are not based on clinical data, but hypothetical case situations and self-report.
  
  
  CONCLUSIONS
  Findings from this study can guide education to address the identified challenges in caring for patients with hematologic malignancies and improving patient care.
