Literature regarding trends for incidence and mortality of scleroderma renal crisis (SRC) in systemic sclerosis (SSc) within the United States (US) emergency departments (EDs) is limited.To study the mortality of SRC among SSc patient encounters within the US EDs.Data from the National Emergency Department Sample (NEDS) constitutes 20% sample of hospital-owned EDs and inpatient sample in the US were analyzed for SSc with and without SRC using ICD-9 codes. A linear p-trend was used to assess the trends.Of the total 180,435 encounters with the diagnosis of SSc in NEDS for the years 2009 2014, 771 or 4.27/1000 patients (mean age 59.6 ± 15.5 years, 75.4% females) were recorded with SRC. The numerical differences in mortality among SRC (32 or 4.1%) and non-SRC subgroups (5487 or 3.1%) did not reach statistical significance (p = 0.3). Major complications among SRC in comparison to non-SRC subgroup include ischemic stroke (5.6% vs 0.98%, p = 0.001), new-onset AF (8% vs 6.9%, p = 0.001), new-onset congestive heart failure (24.1% vs 8.8%, p = 0.001), pulmonary arterial hypertension (15.8% vs 10.9%, p = 0.001), respiratory failure (27.5% vs 10.5%, p = 0.001), and deep vein thrombosis (4.7% vs 4.6%, p = 0.001). Congestive heart failure (CHF) was strongly associated with SRC among SSc (OR 4.3 95%CI 2.7-6.7; p0.001). The absolute yearly rate of SRC had increased over the study years from 2.11/1000 to 5.79/1000 (linear p-trend 0.002) while the mortality trend remained steady.SRC is a relatively rare medical emergency. Although there has been a significant rise in the rate of SRC among SSc patients over the study years, mortality rates had remained steady. SSc patients with CHF should be considered to have low threshold for admission to inpatient services from EDs.
