Background: Telemedicine provides access to specialty care to critically ill patients from a geographic distance. The effects of using telemedicine on (1) teamwork and communication (TC), (2) task workload during resuscitation, and (3) the processes of critical care have not been well described.
Objectives: To evaluate the impact of telemedicine on (1) TC, (2) task workload during a resuscitation, and (3) the processes of critical care during a simulated pediatric resuscitation.
Methods: Prospective single-center randomized trial. Teams of two physicians (senior and junior resident) and two standardized confederate nurses were randomized to either telemedicine (telepresent senior physician team leader) or usual care (both physicians in the room) during a simulated infant resuscitation. Simulations were video recorded and assessed for teamwork, workload, and processes of care using the Simulated Team Assessment Tool (STAT), the NASA Task Load Index (NASA-TLX) tool, and time between onset of ventricular fibrillation and defibrillation, respectively.
Results: Twenty teams participated. There was no difference in teamwork between the groups (mean STAT score 72% vs. 69%;
p = 0.383); however, there was a significantly greater workload in the telemedicine group (mean TLX score 56% vs. 48%, p = 0.020). Using linear regression, no difference was found in time-to-defibrillation between groups (p = 0.671), but higher teamwork scores predicted faster time to defibrillation (p = 0.020).
Conclusions: In this simulation-based study, a telepresent team leader was associated with increased team workload compared to usual care. However, no differences were noted in teamwork and processes of care metrics.
