We evaluated the impact of electronic medical record (EMR)-guided pooled cryoprecipitate dosing vs our previous practice of requiring transfusion medicine (TM) resident approval for every cryoprecipitate transfusion.
At our hospital, cryoprecipitate pooled from five donors is dosed for adult patients, while single-donor cryoprecipitate is dosed for pediatric patients (defined as patients <50 kg in weight). EMR-based dosing guidance replaced a previously required TM consultation when cryoprecipitate pools were ordered, but a consultation remained required for single-unit orders. Usage was defined as thawed cryoprecipitate; wastage was defined as cryoprecipitate that expired prior to transfusion.
In the 6 months prior to intervention, 178 ± 13 doses of pooled cryoprecipitate were used per month vs 187 ± 15 doses after the intervention (P = .68). Wastage of pooled cryoprecipitate increased from 7.7% ± 1.5% to 12.7% ± 1.4% (P = .038). There was no change in wastage of pediatric cryoprecipitate doses during the study period. These trends remained unchanged for a full year postimplementation.
Electronic dosing guidance resulted in similar cryoprecipitate usage as TM auditing. Increased wastage may result from reduced TM oversight. Product wastage should be balanced against the possibility that real-time audits could delay a lifesaving therapy.
我们评估了电子病历(EMR)指导的混合冷沉淀剂量与我们之前要求每袋冷沉淀输血都需经过输血医学(TM)住院医师批准的实践之间的影响。
在我院,从五名供体中混合的冷沉淀用于成人患者,而单供体冷沉淀用于儿科患者(定义为体重<50kg 的患者)。当订购冷沉淀时,基于 EMR 的剂量指导取代了之前需要的 TM 咨询,但仍需要对单个单位的订单进行咨询。使用定义为解冻的冷沉淀;浪费定义为在输血前过期的冷沉淀。
干预前的 6 个月,每月使用混合冷沉淀 178±13 剂量,干预后每月使用 187±15 剂量(P=0.68)。混合冷沉淀的浪费率从 7.7%±1.5%增加到 12.7%±1.4%(P=0.038)。在研究期间,儿科冷沉淀剂量的浪费率没有变化。实施后整整一年,这些趋势保持不变。
电子剂量指导导致冷沉淀的使用与 TM 审核相似。浪费增加可能是由于 TM 监督减少所致。产品浪费应与实时审核可能延迟救生治疗的可能性相平衡。
