Abstract
BACKGROUND: Although stroke rates in Canada are expected to increase dramatically over the next decade, time-driven hyperacute stroke care with thrombolysis increases the likelihood of a good clinical outcome. Following a period of suboptimal performance results for stroke care, our tertiary care center undertook a door-to-needle (DTN) quality improvement initiative. The purpose of our study was to determine if the resulting improved median DTN times and greater proportion of patients treated within 60 minutes of arrival at our emergency department were associated with improved clinical outcomes. METHODS: Guided by the Donabedian quality framework, we retrospectively reviewed charts of consecutive patients (n = 324) who received thrombolysis pre- and post-quality improvement initiative. Data on patient characteristics, and process and outcome measures were collected. Primary study outcomes included mortality, adverse events, discharge location, and independence at discharge. Data analysis compared proportions with Chi Square and means using the two-tailed t-test and a 0.05 level of significance. RESULTS: Median DTN times and the percentage of cases with a DTN ≤60 minutes improved significantly post-intervention (p < 0.001). In-hospital mortality decreased (p = 0.013), and the proportion of favorable versus unfavorable discharge locations improved (p = 0.005). Mortality rates for all study patients with DTN ≤60 versus >60 minutes were also significantly lower (p = 0.044) post-intervention. CONCLUSIONS: Our quality improvement initiative resulted in timelier care and positively influenced clinical outcomes. This study highlights the need for ongoing, innovative investment strategies to ensure timely hyperacute stroke care and optimal patient outcomes.
