Using a low\u2010resolution HLA, a preliminary query (PQ) was performed in all cases with assignment of good or poor score if more or less than 10 MUDs were identified in Bone Marrow Donors Worldwide. Herein we assessed the utility of PQ and of high\u2010resolution (HR) HLA from the start of the search. Moreover, we compared the donor identification and the transplant efficiency between IBMDR and RTN.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>At RTN 79% of 417 patients met a good PQ with a 50% MUD identification versus 12.5% with poor PQ. Our policy led to 78 and 74% of alternative donor identification and transplant efficiency, respectively, higher than IBMDR data equal to 71% (p\u2009=\u20090.007) and 62% (p\u2009&lt;\u20090.0001). The timing for donor identification was significantly reduced using HR HLA at the start of the search from 88 to 66 days at IBMDR (p\u2009&lt;\u20090.001) and from 61 to 41 days at RTN (p\u2009&lt;\u20090.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>Both PQ and HR HLA at the start of the process represents a useful tool to address the search towards the best and timely donor choice.
