We sought to determine if IV tPA use for acute ischemic stroke (AIS) increased in Massachusetts in association with the Primary Stroke Service (PSS) program, a statewide stroke center designation and quality improvement (QI) initiative. We analyzed prospectively acquired data from the Massachusetts Department of Public Health (DPH) between October 2004 and June 2008 including 10,045 consecutive ED-based AIS encounters arriving ≤3 hrs after stroke onset at 69 participating Massachusetts PSS hospitals. The overall rate of IV tPA use was 854/3866 (22.1%) of patients arriving ≤2 hours of symptom onset. IV tPA use increased steadily from 2005 (the first full year of the program) to 2008 (18.4%, 21.9%, 22.6%, 25.5%, p=0.001). Patients treated with IV tPA were more likely to be younger (72.3±14.1 vs. 74.7±14.0, p<0.005) and to have presented after EMS re-routing in July 2005 (96% vs. 94%, p=0.009). Patients who arrived at hospitals with a performance achievement award from the Get With The Guidelines-Stroke program were more likely to receive IV tPA after vs. before award recognition (28.1% vs. 22.3%, p<0.001). In this nearly complete capture of statewide data, rates of IV tPA improved significantly in Massachusetts from 2005 to 2008 in association with a state PSS designation program. Further studies are needed to confirm that treatment disparities exist for older AIS patients, and that the rates of thrombolysis have increased above and beyond secular trends.
