During the study period, there were 946 patient visits identified as having an EAI prescribed from the ED. Fivevisits were excluded because the EAI was not prescribed on ED discharge. Two of these patients were admitted to the hospital and 3 additional patients were either prescribed EAIs from the ED during a non-visit encounter or were prescribed in error and discontinued prior to ED discharge. An additional 224 visits were excluded because we could not determine if the prescriptions were filled inSureScripts. The final analysis included 717 patients.(Figure 1)
The mean age of included patients was 8.1 years (SD=5.7 years). Approximately half of the patients were male, 71% were NH-blackand 60% had either in-state Medicaid or out-of-state Medicaid. Fifty-fourpercent(95% CI 51.1, 58.5) ofEAI prescriptions were filled. (Table 1)
There were no significant associations between EAI fill rates and patient age (mean difference =0.99 years, (95% CI 0.96, 1.01) or sex(p=0.82).In the bivariate analysis, NH-white patientswere more likely to fill EAI prescriptions when compared to NH-blackpatients (OR 1.89, 95% CI 1.11, 3.20) and patients with in-state Medicaid were significantly less likely to fill EAI prescriptions when compared to those patients with commercial or Tricare insurance (OR 0.69, 95% CI 0.48, 0.98). However, when adjusting for covariables there was no significant difference in filling by insurance status or race/ethnicity. (Table 2)
