Physicians' experience in blood supply shortages and the top factors that impact the clinical, economic, and humanistic outcomes of patients with myelodysplastic syndromes in five European countries.

OBJECTIVE
Blood supply shortages may create unnecessary burden, including treatment delay, worsened quality of life, or increased healthcare resource utilization in patients with myelodysplastic syndromes (MDS). This study examined physicians' experience with blood supply shortages in the MDS population. Additionally, physicians' perspectives on the factors that impact clinical, economic, and humanistic outcomes of patients with MDS were investigated.


METHODS
A total of 378 physicians primarily specializing in hematology/oncology across the UK, France, Germany, Italy, and Spain completed the survey (n ≈ 75 in each country). Physicians answered questions regarding adequacy of blood supply for patients with MDS who require red blood cell (RBC) transfusions and identified factors impacting the clinical, economic, and humanistic outcomes in the MDS population.


RESULTS
Over 65% of physicians reported that their patients with MDS requiring RBC transfusions encountered RBC transfusion delays due to blood supply shortage. Among physicians who reported delays, 13.8% of patients were impacted, ranging from 11.0% in Spain to 19.4% in Italy. On average, patients experienced a 4.2-day delay in receiving RBC transfusions due to blood supply shortages, and 16.7% of patients required additional healthcare provider visits. Eastern Cooperative Oncology Group performance status (ECOG PS), threshold hemoglobin levels, and age were the top factors reported by more than two-thirds of physicians that impact outcomes of patients with MDS.


CONCLUSION
Our findings support the need for new treatments in MDS that reduce transfusions and thus blood supply needs, and that would have a beneficial effect on clinical, humanistic, and economic outcomes.
