Key result
Among Medicare beneficiaries aged ≥65 years, adjusted 30-day mortality following an ED visit declined by 0.198% per year from 2009 to 2016 (95% CI, -0.204% to -0.193%; P<.001).
Why the study?
Emergency department visits are common and increasing, but whether outcomes associated with emergency department care are improving over time was largely unknown.
Does 30-day mortality associated with emergency department care among Medicare beneficiaries aged 65 years or older improve over time from 2009 to 2016?

Among US Medicare beneficiaries aged 65 or older, 30-day mortality following an emergency department visit significantly declined from 2009 to 2016, particularly among patients with high illness severity.
Burke et al. (2019) conducted a cross-sectional in Emergency department visits (n=15,416,385). Time (year) was evaluated on 30-day mortality (Trend -0.198% per year, 95% CI -0.204 to -0.193, p=< .001). Among Medicare beneficiaries aged ≥65 years, adjusted 30-day mortality following an ED visit declined by 0.198% per year from 2009 to 2016 (95% CI, -0.204% to -0.193%; P<.001).
