Figure 1 Mean scale scores for the 9 survey factors stratified by ED patient visit volume. The mean scores for physical environment, staffing, equipment and supplies, nursing, and inpatient coordination differed significantly between EDs, with <60,000 visits/year and those with >=60,000 visits/year. Because more than 1 statistical test was performed in analyzing the data, we adjusted the criterion used for statistical significance according to the number of comparisons made. Only those tests that had an α level less than 0.003 were considered to be significant.

Figure 2 Mean scale scores for the 9 survey factors stratified by emergency medicine residency affiliation. EDs were classified as residency affiliated if they served as either a primary or secondary site for an emergency medicine residency program. The mean scores for physical environment, staffing, triage and monitoring, and inpatient coordination were significantly different between residency-affiliated and non–residency-affiliated EDs. Because more than 1 statistical test was performed in analyzing the data, we adjusted the criterion used for statistical significance according to the number of comparisons made. Only those tests that had an α level less than 0.003 were considered to be significant.
