Results of the study found that in Europe, the HDI was associated with both rates and results of HSCT for acute leukemia, with the strongest association related to the few countries in the highest HDI group (eight countries). With regard to rates of HSCT procedures, the team found significant correlations between HDI and total HSCTs performed for AML patients. The strongest associations were found between transplant rates and scores related specifically to LEI and GDPI, suggesting that not only purely economic conditions, but also the organization of the health-care and educational systems likely translate into availability of HSCT.
With regard to patient outcomes, transplants performed in countries in the highest HDI group were associated with significantly higher LFS (68%), which resulted mainly from reduced risk of relapse, as compared with the other four HDI groups (56%, 59%, 63%, and 58%, respectively, in order of increasing HDI score).
"We believe there is still room for improvement in most European states to reach the outcomes achieved by the highest-HDI states, and identifying the factors that contribute to these differences is critical," said Dr. Giebel. "Our study was retrospective in nature, so we would encourage further prospective studies with detailed patient and procedural characteristics to help understand the true differences and design interventions
