Limited access to transcranial Doppler screening and stroke prevention for children with sickle cell disease in Europe: Results of a multinational EuroBloodNet survey

Abstract

AbstractBackgroundEnsuring equitable access to adequate standard of care for patients with rare hematological disease is one of the aims of the European Reference Network (ERN) EuroBloodNet. Stroke is one of the most devastating complications for children with sickle cell disease (SCD). For effective prevention of stroke risk, annual transcranial Doppler (TCD) according to a defined protocol is recommended for patients aged 2–16 years, with red blood cell transfusion therapy for those at risk. There is no information regarding screening for stroke risk and stroke prevention programs in Europe.MethodsSeven SCD experts of five healthcare providers (HCPs) of ERN EuroBloodNet developed an online survey to assess the access to TCD screening and stroke prevention programs for children with SCD in Europe.ResultsEighty‐one experts in 77 HCPs from 16 European countries responded to 16 online questions. Thirty‐two of 77 (51%) HCPs were EuroBloodNet reference centers, and 36% physicians reported not having a dedicated TCD/TCD imaging service for children with SCD. Only 30% of physicians provided estimates that all their patients received annual TCD according to the standard protocol due to lack of trained staff (43%), lack of TCD instruments (11%), refusal of patients due to logistical difficulties (22%), and lack of funds for dedicated staff or equipment (11%).ConclusionsThis multinational European survey provides the first comprehensive picture of access to TCD screening and stroke prevention in European countries. Identifying the potential underlying causes of the lack of effective standardized screening, this survey also addresses possible dedicated actions to cover these needs.
