Background Delays in delivering endovascular stroke therapy adversely affect outcomes. Time-sensitive treatments such as stroke interventions benefit from methodically developed protocols. Clearly defined roles in these protocols allow for parallel processing of tasks, resulting in consistent delivery of care. Objective To present the outcomes of a quality-improvement (QI) process directed at reducing stroke treatment times in a tertiary level academic medical center. Methods A Six-Sigma-based QI process was developed over a 3-month period. After an initial analysis, procedures were implemented and fine-tuned to identify and address rate-limiting steps in the endovascular care pathway. Prospectively recorded treatment times were then compared in two groups of patients who were treated before' (n=64) or after' (n=30) the QI process. Three time intervals were measured: emergency room (ER) to arrival for CT scan (ER-CT), CT scan to interventional laboratory arrival (CT-Lab), and interventional laboratory arrival to groin puncture (Lab-puncture). Results The ER-CT time was 40 (29)min in the before' and 26 (+/- 15)min in the after' group (p=0.008). The CT-Lab time was 87 (+/- 47)min in the before' and 51 (+/- 33)min in the after' group (p=0.0002). The Lab-puncture time was 24 (+/- 11)min in the before' and 15 (+/- 4)min in the after' group (p<0.0001). The overall ER-arrival to groin-puncture time was reduced from 2h, 31min (+/- 51) min in the before' to 1h, 33min (+/- 37) min in the after' group, (p<0.0001). The improved times were seen for both working hours and off-hours interventions. Conclusions A protocol-driven process can significantly improve efficiency of care in time-sensitive stroke interventions.
