Was due largely to gains at the non-teaching hospitals But both groups showed improvements Demonstrates that experience matters!! Perhaps diversion of acute patients to specific facilities leads to improved care efficiency, comfort levels, and program development Limitations Much of the data obtained from databases Much of the data generated by self-reporting Few audited results We did not analyze nor control for many confounding factors: Risk stratification SES Reasons for exclusion from treatment Ascertainment biases Conclusions TPA utilization at certified PSCs is associated with the duration of time a hospital has been a Stroke Center While TPA utilization is higher initially at teaching hospitals, over time the non-teaching hospitals are able to achieve high levels of TPA use Experienced teaching hospitals have the highest rate of TPA utilization Conclusions These data further support the importance of PSCs and how time and experience improve some aspects of acute stroke care The vast majority of patients at a PSC do not receive TPA, but still benefit from other aspects of organized care at these facilities
