Safety gaps in medical team communication: Results of quality improvement efforts in a cardiac catheterization laboratory

Abstract

To assess closed-loop communications (readback), a fundamental aspect of effective communication, among cardiovascular teams and assess improvement efforts. Effective communication within teams is essential to assure safety and optimal outcomes. Readback of verbal physician orders is a hospital and national requirement. Single-center observational study, where the readback responses to physician verbal orders in the catheterization laboratory were characterized over three distinct time intervals from 2015 to 2017. Performance feedback and focused education on the value of readbacks was provided to the teams in two waves, with subsequent remeasurement. Responses to verbal orders were characterized as complete (all important parameters of the order repeated for verification), partial, acknowledgement only, or no response. Changes in readback performance after quality interventions were assessed. During the first-observational period of 101 cases, complete readback occurred in 195 of 515 (38%) medication orders and 136 of 235 (58%) equipment orders. After initial quality improvement efforts, 102 cases were observed. In these, 298 of 480 (62%) medication orders had complete readback, and 210 of 420 (50%) equipment orders had complete readback. After additional quality improvement efforts, 168 cases were observed. In these, 506 of 723 (70%) medication orders had complete readback, and 630 of 1,061 (59%) equipment orders had complete readback. Overall, medication order readback improved over time (correlation = 0.26 [-0.30, -0.21]; p < 0.001), but equipment order readback did not (correlation = 0.02 [-0.07, 0.03]; p = 0.44). Closed-loop communication of physician verbal orders was used infrequently in this medical team setting and proved difficult to fully improve. This is an important safety gap.
