An online educational module on transfusion safety and appropriateness for resident physicians: a controlled...

Several professional societies have made value-based statements in support of restrictive transfusion strategies. The aim of this study was to determine whether completion of an accredited online training program in transfusion safety could improve transfusion knowledge among medical residents and increase transfusion appropriateness.

We performed a controlled before-after evaluation of a mandatory accredited self-directed training program (Bloody Easy Lite for Physicians) that provides education about transfusion medicine on a 47-bed medical clinical teaching unit at a university-affiliated hospital centre in Montréal. The program consists of 2 modules and takes about 30 minutes to complete. We used the 45-bed medical teaching unit at another Montréal hospital as a contemporary control. We compared resident physicians' pre- and posttest scores and evaluated the impact on transfusion appropriateness by comparing the proportion occurring below a hemoglobin concentration of 80 g/L before (April 2013-June 2015) and after (July 2015-January 2016) the intervention.

Of the 55 residents on the intervention unit, 53 (96%) completed the training. The median pretest score was 50% (inter-quartile range [IQR] 40%-60%). The median posttest score was 90% (IQR 80%-90%) for module 1 and 80% (IQR 80%-90%) for module 2 (p < 0.001 for both pre-post comparisons). The proportion of transfusions below 80 g/L increased from 80.1% to 86.9% (p = 0.04) on the intervention unit and remained relatively unchanged on the control unit (75.6% v. 71.1%, p = 0.4). Although there was no statistically significant difference between the units in the proportion of transfusions below 80 g/L before the intervention (p = 0.07), a significant difference was observed after the intervention (p = 0.002).

Mandatory training in transfusion safety via an online program resulted in improved transfusion knowledge among residents and an increase in the proportion of transfusions occurring at a hemoglobin concentration below 80 g/L. This low-cost educational initiative may improve transfusion appropriateness.
