BACKGROUND

In May 2012, an updated stroke algorithm was implemented at Vanderbilt University Medical Center. The current study objectives were to: (1) describe the process of implementing a new stroke algorithm and (2) compare pre- and post-algorithm quality improvement (QI) metrics, specificaly door to computed tomography time (DTCT), door to neurology time (DTN), and door to tPA administration time (DTT).

METHODS

Our institutional stroke algorithm underwent extensive revision, with a focus on removing variability, streamlining care, and improving time delays. The updated stroke algorithm was implemented in May 2012. Three primary stroke QI metrics were evaluated over four separate 3-month time points, one pre- and three post-algorithm periods.

RESULTS

The following data points improved after algorithm implementation: average DTCT decreased from 39.9 to 12.8 min ( < 0.001); average DTN decreased from 34.1 to 8.2 min ( ≤ 0.001), and average DTT decreased from 62.5 to 43.5 min ( = 0.17).

CONCLUSION

A new stroke protocol that prioritized neurointervention at our institution resulted in significant lowering in the DTCT and DTN, with a nonsignificant improvement in DTT.
