Stroke Center Certification and Performance: A Longitudinal Analysis of the Northeast Cerebrovascular Consortium Region

Background: The NorthEast Cerebrovascular Consortium (NECC) was established in 2006 to improve stroke-systems-of-care models. Methods: This study evaluates the increase in stroke quality over time in NECC and Non-NECC regions, defined as the change in proportion of hospitals over time who received State or National Primary/Comprehensive Stroke Center (PSC/CSC) certification, participated in a national quality program (Get-With-The-Guidelines-Stroke (GWTG-S)), or received GWTG-S Performance Achievement Awards (PAA) from 2005-2013. Analysis of trends was performed (Cochran-Armitage/Cochran-Mantel-Haenszel tests; Generalized-Estimating Equations). As an exploratory analysis eight NECC region Departments of Health (DOH) were surveyed regarding perceptions of the NECC. Results: During the study period, there were 433.1 ± 10.2 vs 3986.4 ± 187.7 hospitals per year in the NECC vs non-NECC regions. Rate of growth per year increased in both groups for each measure but to a greater degree in the NECC vs Non-NECC regions: PSC/CSC (5.4%/yr vs 3.2%/yr), GWTG-S participation (5.0%/yr vs 2.9%/yr), and PAAs (5.2%/yr vs 2.1%/yr), with state-based certification growth also being higher in the NECC region (4.2%/yr vs 0.4%/yr; all comparisons p < 0.0001). After adjusting for year, significantly more NECC hospitals had PSC/CSC certification, GWTG-S participation, and GWTG-S PAAs than non-NECC sites (all analyses p < 0.0001). One hundred percent of NECC region DOHs were aware of the NECC and involved in functions, 87.5% indicated the NECC provided beneficial assistance. Conclusions: There has been a higher rate of growth of state certification contrasted to national PSC/CSC certification, and a higher rate of growth of participation and achievement in GWTG-S in the northeast region compared to other US regions.
