Inefficiencies in procedure room management can delay patient care and waste resources. Rapid room turnaround time (RTT) requires multiple tasks be completed in a brief window of opportunity. We examine the effect of dedicated radiology transporters and a clinical nurse coordinator on room utilization metrics in the interventional radiology (IR) department. A prospective database of event times related to room workflow was created for all cases performed in a 4-angiosuite IR department at a 900-bed tertiary care hospital. Cases with incomplete data were excluded. Log-linear gamma regression models were used to assess the impact of radiology-specific transporters and, 11 weeks later, charge nurse implementation, on RTT and case start delay. Covariates were included in each model to control for possible patient-level and procedure-level effects. All analyses were performed in SAS 9.4 (SAS Institute, Inc., Cary NC). In total, 5837 and 1018 cases were included in the RTT and case start delay analyses, respectively, from October 2017 to March 2020. The mean RTT and case delay times were 67.3 and 25.8 minutes, respectively. The effect of radiology transporters were not independently significant using a 5% confidence interval, associated with an estimated 5.2% (-0.5%,11.2%) increase in RTT (P = 0.062) and a 2.0% (-22.5%,21.6%) reduction in case start delay (P = 0.861) on average. Subsequent IR charge nurse implementation was associated with an estimated 7.6% (3.1%,11.8%,) reduction in RTT (P < 0.001) and 22.0% (8.3%,33.7%) reduction in case start delay (P = 0.003) on average. Increase in transporters alone did not independently improve room utilization metrics. Addition of a clinical coordinator role yielded significantly improved RTT and case start delay times.
