According to Edward Blakeney's professional profile, he states that in his capacity as a Blood Conservation Coordinator for Tenet Healthcare, he " Facilitated contract with Jehovah's Witnesses Headquarters".
Does anybody know what kind of 'contract' would be required from the Society for the administration of bloodless medicine?
