Objective Few studies have estimated the healthcare resource usage of patients with systemic sclerosis (SSc). The purpose of this study was to compare hospitalization among incident cases of SSc vs age- and sex-matched comparators. Methods A retrospective, population-based cohort of patients with SSc in Olmsted County, MN from Jan 1, 1980 to Dec 31, 2016 was assembled. A 2:1 cohort of age- and sex-matched patients without SSc from the same population was randomly selected for comparison. All hospitalizations in the geographic area from Jan. 1, 1987 to Sept. 30, 2018 were obtained. Rates of hospitalization, lengths of stay, and readmissions were compared between groups. Results 76 incident SSc cases and 155 non-SSc comparators (mean age of 56 ± 16 years at diagnosis/index, 91% female) were included. Rates of hospitalization among cases and comparators were 31.9 and 17.9 per 100 person-years, respectively (rate ratio [RR]:1.78; 95% confidence interval (CI):1.52-2.08). Hospitalization rates were higher in patients with SSc than comparators during the first 5 years after SSc diagnosis (RR: 2.16; 95%CI: 1.70-2.74). This difference decreased over time and was no longer significant at ≥15 years after SSc incidence/index. Lengths of stay (median (IQR) 4 (2-6) vs 3(2-6); p=0.52) and readmission rates (25% vs 23%; p=0.51) were similar between groups. Conclusion Patients with SSc were hospitalized more frequently than comparators, indicating high inpatient care needs in this population. Hospitalization rates were highest during the first 5 years following SSc diagnosis.

Background:Systemic sclerosis (SSc) is a complex immune-mediated disease with heterogeneous manifestations, which is characterized by vasculopathy and fibrosis of the skin and visceral organs. Mortality associated with SSc exceeds that of other rheumatic diseases, though population-based studies assessing recent trends in survival are lacking.Objectives:We aimed to determine the incidence and prevalence of physician-diagnosed SSc in a population-based cohort over a 39-year time period, and assess for trends in survival over time.Methods:Medical records of patients with a diagnosis or suspicion of SSc in a geographically well-defined area from Jan 1, 1980 to Dec 31, 2018 were reviewed to identify incident cases of SSc. Cases were defined by physician diagnosis of SSc, and fulfillment of the 2013 ACR/EULAR classification criteria was ascertained. Prevalent cases of SSc on Jan 1, 2015 were also identified. Incidence and prevalence rates were age- and sex-adjusted to the 2010 U.S. white population. Survival rates were compared with expected rates in the general population.Results:85 incident cases of SSc (91% female, mean age 55.4 ± 16 y) and 49 prevalent cases on Jan 1, 2015 were identified. Patients had a mean 11.7 (SD 9.4) years of follow-up available. The overall age and sex adjusted annual incidence for 1980-2018 was 2.5 (95% CI: 2.0-3.1) per 100,000 population, with no change in incidence over time (p=0.32). The age-adjusted incidence was 4.4 (95% CI: 3.4-5.4) for females, and 0.56 (95% CI: 0.16-0.96) for males per 100,000 population. The age- and sex-adjusted prevalence on Jan 1, 2015 was 43.6 (95% CI: 31.3-55.8) per 100,000 population.77 (91%) patients fulfilled the 2013 classification criteria; 38 (45%) fulfilled 1980 criteria. 70 (82%) had limited cutaneous involvement, 12 (14%) had diffuse cutaneous involvement, and 3 (4%) had sine scleroderma. At SSc diagnosis, 80 (94%) patients had Raynaud’s, 43 (51%) had sclerodactyly, 39 (46%) had telangiectasias, 14/48 (29%) had abnormal nailfold capillaries, 16/35 (46%) had digital ulcers or fingertip scarring, 8 (9%) had interstitial lung disease (ILD), and 7 (8%) had pulmonary arterial hypertension (PAH). 77/82 patients (91%) had a positive antinuclear antibody. 44 (52%) had a known SSc-related autoantibody: 32 (73%) with anti-centromere, 9 (20%) with anti-Scl-70, and 4 (9%) with anti-RNA-polymerase III.Survival was 77% (95% CI: 69-87) at 5 years, 66% (95% CI: 56-78) at 10 years, and 42% (95% CI: 30-57) at 20 years, with no evidence of improved survival over time (p=0.46). Age (Hazard ratio [HR]: 1.49 per 10 year increase; 95% CI 1.19-1.88), smoking at time of diagnosis (HR: 2.37; 95% CI: 1.05-5.34), digital ischemia (HR: 2.54; 95% CI: 1.33-4.87), ILD (HR: 4.00; 95% CI: 2.11-7.59), and PAH (HR: 4.30; 95% CI: 2.24-8.25) had significant associations with mortality. Survival of patients with SSc was poorer than the general population (standardized mortality ratio: 2.48; 95% CI: 1.76-3.39).Conclusion:The average incidence of SSc in this population-based cohort spanning 39 years was 2.5 per 100,000 population, with no change in incidence over time. Age, smoking, digital ischemia, ILD and PAH were risk factors for poorer survival. Overall survival for patients with SSc is worse than that of the general population and shows no improvement over time, suggesting continued need for improved diagnostic and treatment measures.Figure 1.Survival of 85 Olmsted County residents with SSc compared with expected survival rates from Minnesota lifetables (observed: solid line, expected: dashed line).Disclosure of Interests:None declared

Background/Purpose: To update the epidemiology of systemic sclerosis and evaluate the performance of the American College of Rheumatology/European League Against Rheumatism 2013 versus 1980 American Rheumatism Association classification criteria in a US population-based cohort. Methods: An inception cohort of patients with incident systemic sclerosis from 1 January 1980 through 31 December 2018, in Olmsted County, Minnesota, was identified based on comprehensive individual medical record review. Incidence and prevalence rates were age- and sex-adjusted to the 2010 US white population. Survival rates were compared with expected rates in the general population. Fulfillment of 1980 and 2013 classification criteria was ascertained. Results: A total of 85 incident cases of systemic sclerosis (91% female, mean age = 55.4 ± 16 years) and 49 prevalent cases on 1 January 2015 were identified. The overall age- and sex-adjusted annual incidence was 25 (95% confidence interval = 20–31) per million population, with no change in incidence over time. The age- and sex-adjusted prevalence was 436 (95% confidence interval = 313–558) per 1,000,000 population. 77 (91%) patients fulfilled the 2013 classification criteria, and 38 (45%) fulfilled the 1980 criteria. Mortality among patients with systemic sclerosis was significantly higher in comparison to the general population, with a standardized mortality ratio of 2.48 (95% confidence interval = 1.76–3.39) and no evidence of improvement over time. Conclusion: Systemic sclerosis developed in 25 persons/million/year with no change over the 39-year study period. The 2013 classification criteria perform significantly better than the 1980 criteria but failed to classify 9% of patients. Systemic sclerosis portends a 2.5-fold higher risk of mortality than the general population, with no evidence of improved survival over time.

Background: Recent population-based studies have revealed declining ischemic stroke hospitalization rates in the US, particularly among whites, but no study has assessed recent nationwide trends in race/ethnic-, age- and sex-specific stroke hospitalization rates in the US. Aims: To assess temporal trends in race/ethnic-, age-, and sex-specific rates of hospitalization for ischemic stroke in the US. Methods: Temporal trends in hospitalization for ischemic stroke (ICD-9 codes 433.x1, 434, 436) from 2000 to 2010 were assessed among adults ≥25 years using the Nationwide Inpatient Sample. Age-, sex-, and race/ethnic-specific stroke hospitalization rates were calculated using the weighted number of hospitalizations as the numerator and the US civilian population as the denominator. Age-adjusted rates were standardized to the 2000 US Census population. Results: From 2000 to 2010, age-adjusted stroke hospitalization rates decreased from 169 to 138 per 100,000 (overall rate reduction 18.3%). The decline in stroke hospitalizations was driven by the ≥65 age group, with the sharpest decline among 65-84 year olds (Figure). Sex-specific rates showed higher age-adjusted rates in women, with a steeper reduction in women than in men (from 228 to 180 vs. 183 to 157 per 100,000). Race/ethnic-specific trends revealed that hospitalizations decreased for whites and Hispanics but increased for blacks (from 144 to 193 per 100,000 in black men and from 191 to 211 per 100,000 in black women). Discussion: Although overall stroke hospitalizations have decreased in the US, the reduction has been more pronounced among older individuals, whites and Hispanics. Renewed efforts at targeting risk factor control among blacks and middle-aged individuals may be warranted. Figure 1.

Abstract Abstract 1774 Poster Board I-800 Background Population-based data on myelodysplastic syndromes (MDS) are scarce. Since its inception in 1982, the Düsseldorf MDS Registry has captured 3598 patients with MDS, of whom 21 % live in the town district of Düsseldorf. Between 1996-2005 we are confident that all MDS patients residing in the town district of Düsseldorf were entered and followed in the registry through regular follow-ups. As yearly age- and sex-specific population counts are also available for Düsseldorf, the Registry provides a unique opportunity to estimate MDS disease frequency. Here we aim to quantify the incidence and prevalence of MDS disease subtypes. Methods Patients were identified from the MDS Registry. Age- and sex-specific yearly population counts were obtained from the Statistical Office of North-Rhine Westphalia. The number of residents in Düsseldorf minimally increased during the study period from 1996 to 2005 (mean: 571,000 residents). The number of patients with a first-time MDS diagnosis in a given calendar year (incident cases) was divided by the total Düsseldorf population in that year to estimate incidence. Prevalence was estimated by dividing the number of existing plus incident MDS patients in a given year by the total population of Düsseldorf that year. Incidence (per 100,000 person-years (PY) and prevalence per 100,000 persons are presented with corresponding 95% confidence intervals (CI) calculated using the delta and Wilson methods, respectively. Low-risk MDS was defined as WHO subtypes RA, RCMD or MDS with del(5q). High-risk included subtypes RAEB-I and RAEB-II. Results 344 MDS patients were included in our analyses (279 incident patients). Incidence and prevalence of low-risk MDS was 2.87 (95%CI 2.46–3.35) per 100,000PY and 12.4 (95%CI 11.5–13.4) per 100,000 persons, respectively, with no difference between men and women (Table). High-risk disease was less common. The incidence of high-risk disease in men appeared to be higher (1.22 (95%CI 0.87–1.72) per 100,000PY) than in women (0.63 (95%CI 0.40–0.99) per 100,000PY). Prevalence of high-risk disease among men was statistically significantly higher in men compared to women (2.93 (95%CI 2.35 – 3.65) per 100,000 persons) and 1.56 (95%CI 1.17 – 2.08) per 100,000 persons), respectively (Table). Conclusion In this population-based study we found that MDS more common in men than in women. The majority of MDS cases had low-risk disease. Incidence and prevalence of high risk disease (but not low risk) is higher in men compared to women. Financial disclosures: This study was supported by Amgen Inc.

Background:Systemic sclerosis (SSc) can impact multiple areas of the heart through fibrotic and vascular processes; leading to variable cardiac involvement including electrocardiogram (ECG) abnormalities. Conduction and rhythm disorders are associated with worse prognosis in patients with SSc. (1, 2)Objectives:To study the incidence, risk factors and outcomes of conduction and rhythm disorders in a US population-based cohort of patients with SSc and non-SSc comparators from the same geographic area.Methods:A previously identified incident cohort of SSc patients (1980-2016) in a well-defined geographic area was compared to a randomly selected 2:1 cohort of age- and sex-matched non-SSc subjects from the same population base. Demographics, disease characteristics, cardiovascular risk factors and laboratory tests were abstracted by manual record review. ECGs and Holter ECGs were reviewed to determine the occurrence of any conduction or rhythm abnormalities. The need for cardiac interventions was also abstracted.Results:78 incident SSc cases and 156 non-SSc comparators were identified [age 56 years± 15.7, 91% female]. Prevalence of any conduction disorders before SSc diagnosis compared to non-SSc comparators was 15% vs. 7% (p=0.06), and any rhythm disorder was 18% vs. 13% (p=0.33). During a median follow up of 10.5 years in patients with SSc and 13.0 years in non-SSc comparators, conduction disorders developed in 25 SSc patients with a cumulative incidence (ci) of 20.5% (95% CI: 12.4-34.1%) compared to 28 non-SSc patients with ci of 10.4% (95% CI: 6.2-17.4%) (HR: 2.57; 95% CI: 1.48-4.45), while rhythm disorders developed in 27 SSc patients with ci of 27.3% (95% CI: 17.9-41.6%) vs 43 non-SSc patients with ci of 18.0% (95% CI: 12.3-26.4%) (HR: 1.62; 95% CI: 1.00-2.64). (Figure 1).Conduction disorders in patients with SSc during follow up included: 1st-degree atrioventricular block (AVB) (n=12), 2nd-degree AVB (n=1), 3rd-degree AVB (n=1), right bundle branch block (n=10), left bundle branch block (n=4), bifascicular block (n=6), and prolonged-QT (n=13). Rhythm disorders included: atrial fibrillation (n=10), atrial flutter (n=4), supraventricular tachycardia (n=4), ventricular tachycardia (n=1), and premature ventricular contractions (n=16).Pulmonary hypertension (PHT) was the only significant risk factor identified for development of both conduction and rhythm disorders (HR=8.38, 95% CI: 1.32-53.40 and HR=8.07, 95% CI: 1.60-40.74, respectively). Current smoking significantly increased the risk for development of rhythm disorders (HR=2.91, 95% CI: 1.19-7.12). Conduction and rhythm disorders were associated with increased mortality among patients with SSc (HR=7.60, 95% CI: 3.49-16.55 and HR=4.87, 95% CI: 2.28-10.42, respectively, after adjusting for age, sex and calendar year of diagnosis).Conclusion:Patients with SSc have a significantly higher prevalence of conduction disorders at disease onset than non-SSc comparators. During the course of their disease, their risk of developing conduction disorders is 2.6-fold, and risk of rhythm disorders is 1.6-fold increased, compared to non-SSc subjects.PHT was significantly associated with increased risk of developing conduction and rhythm disorders among patients with SSc, a finding that should warrant increased vigilance and screening for ECG abnormalities in this population.References:[1]Tyndall A.J. et al.

<b><i>Background:</i></b> Patients with epilepsy have a higher mortality rate than the general population. Up-to-date estimates of epilepsy incidence, prevalence, and medication use are critical to assist policymaking. <b><i>Methods:</i></b> Using the National Taiwan Insurance Research Database, the standardized incidence and prevalence of epilepsy were estimated in each calendar year from 2007 to 2015. We used the incident cases of epilepsy to analyze the change in prescribing patterns from 2007 to 2015. Joinpoint regression was used to estimate secular trends. <b><i>Results:</i></b> From 2007 to 2015, the age- and sex-standardized incidence decreased from 0.72 (95% confidence interval [CI] 0.70–0.73) to 0.54 (95% CI 0.53–0.55) per 1,000 person-years, giving an annual percentage change (APC) of −2.73 (<i>p</i> &#x3c; 0.05). Among patients younger than 20 years, the incidence did not change significantly. The age- and sex-standardized prevalence decreased from 6.94 (95% CI 6.90–6.98) to 6.86 (95% CI, 6.82–6.89) per 1,000 people, giving an APC of −0.31 (<i>p</i> &#x3c; 0.05). However, the prevalence increased in the 35- to 49- and 50- to 64-year age-groups. The most common first-line anticonvulsant was phenytoin in 2007 and valproate in 2015. The use of levetiracetam, clobazam, and valproate increased during the study period, with APCs of 25.48% (95% CI 19.97–31.24), 6.41 (3.09–9.85), and 2.83 (1.51–4.16), respectively. The use of carbamazepine, phenytoin, and topiramate decreased; the APCs were −23.86% (95% CI −25.25 to −22.44), −6.61 (−8.40 to −4.79), and −4.29% (−7.87 to −0.57), respectively. <b><i>Conclusions:</i></b> The overall prevalence and incidence of epilepsy decreased slightly from 2007 to 2015. The prescribed first-line anticonvulsant also changed over time.

Background: Self-poisoning (overdose) is the commonest form of self-harm cases presenting to acute secondary care services in the UK, where there has been limited investigation of self-harm in black and minority ethnic communities. London has the UK’s most ethnically diverse areas but presents challenges in resident-based data collection due to the large number of hospitals. Aims: To investigate the rates and characteristics of self-poisoning presentations in two central London boroughs. Method: All incident cases of self-poisoning presentations of residents of Lambeth and Southwark were identified over a 12-month period through comprehensive acute and mental health trust data collection systems at multiple hospitals. Analysis was done using STATA 12.1. Results: A rate of 121.4/100,000 was recorded across a population of more than half a million residents. Women exceeded men in all measured ethnic groups. Black women presented 1.5 times more than white women. Gender ratios within ethnicities were marked. Among those aged younger than 24 years, black women were almost 7 times more likely to present than black men were. Conclusion: Self-poisoning is the commonest form of self-harm presentation to UK hospitals but population-based rates are rare. These results have implications for formulating and managing risk in clinical services for both minority ethnic women and men.
