Meningococcal vaccination is recommended for patients with complement component deficiencies (CDs) in the United States. In this retrospective database study, only 4.6% and 2.2% of patients received MenACWY and MenB vaccination, respectively, within 3 years of CD diagnosis. Thus, meningococcal vaccination rates among patients with CDs need to be improved.

Dear Editor, Staphylococcal scalded skin syndrome (SSSS) is a rare dermatologic disease caused by toxigenic strains of Staphylococcus aureus. Adult SSSS is less common than pediatric cases of the disease, likely due to the development of immunity early in life, but has a higher fatality rate 1-3 . These facts hint at the different clinical nature of SSSS between patients of different ages.

Background The European Society of Cardiology (ESC) guidelines suggest that greater absolute reduction in low-density lipoprotein cholesterol (LDL-C) leads to greater cardiovascular risk reduction. Several lipid-lowering treatments (LLTs) are available in Germany; however, the research on treatment patterns and LDL-C outcomes among patients (pts) receiving LLTs in real-world setting is limited. Purpose To characterize the pts characteristics, treatment patterns and LDL-C outcomes of pts with atherosclerotic cardiovascular disease (ASCVD) with hypercholesterolemia (ASCVD-H) in Germany. Methods This is a descriptive, non-interventional, retrospective cohort study of ASCVD-H pts identified from general physician (GP) practices available in the electronic medical record (EMR) database Disease Analyzer (January 1992-June 2020) in Germany. ASCVD-H pts were included if they had a recorded diagnosis, were prescribed LLTs or had LDL-C levels of ≥55 mg/dL anytime within 6 months before and 3 months after the index date (ID), as per the data recorded by the participating physician. The first encounter of ASCVD after hypercholesterolemia during the identification period (1/07/2015–30/06/2019) was considered as the ID. Persistence was measured as the duration (in days) with allowed gap of 60 days and adherence as proportion of days covered (PDC) within 12 and 24 months after ID. Results We included 147,905 pts with ASCVD-H (57.2% male; mean age: 70.6 yrs; ≥75 yrs-old: 43.3%; mean BMI: 29.0 kg/m2). Coronary artery disease was the most common index diagnosis (73.2%), followed by cerebrovascular disease (31.7%) and peripheral vascular disease (21.5%). Hypertension (83.5%) and diabetes (27.6%) were the most common comorbidities among these pts. At ID, statin monotherapy (58.6%) was the most commonly prescribed LLT, with simvastatin being the most common drug (36.4%). The use of PCSK9 inhibitors, ezetimibe and fibrates was very limited ( Conclusions Pts with ASCVD-H in Germany treated by GPs are elderly pts with multiple cardiovascular comorbidities. LDL-C was measured in nearly half of the pts, and almost all had LDL-C ≥55 mg/dL at ID. Findings indicate low prescription of LLTs in GP setting, particularly non-statin LLTs. The mean adherence (PDC) to statin monotherapy was 72% within the 24-month after ID. Data suggest the need for newer therapies with potential to control LDL-C levels.

Background and Aims Anaemia is a common complication in patients with NDD-CKD, and its prevalence increases with advancing CKD stage.1,2 It is a risk factor for both CKD progression and other adverse outcomes, including major adverse cardiac events, hospitalisation and all-cause mortality.1 We aim to report the prevalence of NDD-CKD stage 3a–5 in Italy, and to evaluate the prevalence and incidence of anaemia among patients with NDD-CKD. Of those patients with anaemia, we seek to establish the size of the patient pool eligible for ESAs, and consequently, the proportion of patients treated with ESAs. Method Patients ≥18 years of age with a record of NDD-CKD stage 3a–5 between 1 January 2014 and 31 December 2016 were identified from databases of five Local Health Units (LHUs) across Italy. NDD-CKD stage 3a–5 in our study was defined as either ≥1 hospitalisation record with discharge diagnosis of CKD (ICD-9-CM 585.x, where x = 3, 4, or 5) or ≥1 record of estimated glomerular filtration rate (eGFR) Results For 2016, the prevalence of NDD-CKD stage 3a–5 in the population aged ≥18 years was 5.6% (83,625/1,507,391): CKD stage 3a was the most common (4.2%; 62,683/1,507,391), while the prevalence of each of the stages 3b–5 was ≤1.0% (Table). The prevalence and incidence of anaemia among patients with NDD-CKD stage 3a–5 in 2016 was 33.8% and 11.4%, respectively. The prevalence of anaemia increased with CKD stage: from 28.2% among patients with stage 3a to 78.9% among those with stage 5. A similar trend was observed for incidence, which increased from 9.3% for stage 3a to 32.8% for stage 5. The proportion of patients with NDD-CKD stage 3a–5 and anaemia who were eligible for ESA treatment from 2014–2016 ranged from 51.9% to 75.6% across the CKD stages. In 2016, the proportion of patients with incident NDD-CKD anaemia who were eligible for ESAs but not treated was 42.3%. This proportion was similar across the CKD stages, except for stage 5, for which the proportion of patients who were eligible but not ESA treated was 51.1%. Conclusion In Italy, we found that higher CKD stages are associated with increased prevalence and incidence of anaemia in NDD-CKD, a finding which is supported by previous research in other countries worldwide.1,2 Despite this, almost half of patients with anaemia of NDD-CKD stage 3a–5 were eligible for ESA treatment but did not receive ESAs. This suggests that anaemia may not be adequately controlled in patients with NDD-CKD stage 3a–5, and may need further attention and treatment.

Background IPD and pneumonia are associated with high mortality and healthcare resource utilization (HCRU). This analysis assessed incidence, HCRU and costs of IPD and pneumonia following PCV13 introduction in 2010 in Veneto. Methods IPD, unspecified invasive disease episodes, outpatient pneumococcal and unspecified pneumonia episodes were identified in Pedianet, a pediatric primary care database from 2010-2017. HCRU includes primary care and specialist visits, antibiotic prescriptions, diagnostics, ER visits and hospitalizations. Incidence rates (IRs) were numbers of episodes/1,000 person-years. Standardized regional incidence rates (SRIRs) were calculated by standardizing IRs with regional population data by age and year. Regional expenditures (€/1,000 person-years) were calculated by multiplying SRIRs with average costs per episode. Interrupted time series (ITS) analyses assessed trends in annual IRs in the early and late PCV13 (2010-2013, 2014-2017) periods. Results During 2010-2017, IPD and unspecified invasive disease incidence decreased from 0.40 to 0.31/1,000 person-years. While incidence was numerically lower in 2017 than in 2010, ITS analysis did not detect a significant trend in the early (coef=1.97; p = 0.63) or late PCV13 (coef=0.50; p = 0.90) periods. Average cost per episode was €4206 and average regional expenditure was €171/1,000 person-year. SRIR for outpatient pneumonia decreased from 13.35 to 5.48/1,000 person-year during 2010 to 2017. Pneumonia episodes were associated with 0.29 ER visits and 0.15 short stay and 0.06 long stay hospitalization. Average cost per episode was €345, majority of which was associated with ER visits (€50.8) and hospitalizations (€243.9). Regional expenditures decreased from €12852.31 to €5351.98/1,000 person-year. Conclusions IPD and unspecified invasive disease burden did not change significantly following PCV13 introduction, while disease burden declined for outpatient pneumococcal and unspecified pneumonia. Key messages IPD and unspecified invasive disease burden did not change significantly following PCV13 introduction. Disease burden declined for outpatient pneumococcal and unspecified pneumonia following PCV13.

Background Acute Otitis Media (AOM) causes substantial healthcare resource utilization (HCRU) in children. This analysis assessed AOM HCRU and costs following PCV13 introduction in 2010 in Veneto. Methods AOM episodes in children Results Simple AOM episodes were associated with 1.03 primary care visits and 1.52 antibiotic prescriptions on average. Only 2.4% and 0.18% of simple AOM episodes included an ER visit, and a hospitalization respectively. Recurrent AOM episodes were associated with 1.06 primary care visits and 1.62 antibiotic prescriptions. Annual costs per episode were €50 for simple AOM and €54.2 for recurrent AOM, majority of which were associated with primary care visits and antibiotic prescriptions. Average antibiotic prescription costs were €14.2 for simple AOM and €16 for recurrent AOM. During 2010 and 2017, SRIRs declined from 100 to 72/1000 person-year for simple AOM and from 13 to 11/1,000 person-year for recurrent AOM. Regional expenditures decreased from €4702.7 to €3358.5/1,000 person-year for simple AOM and from €672.4 to €572.6/1000 person-year for recurrent AOM. Conclusions SRIRs and regional expenditures declined for simple and recurrent AOM after PCV13 introduction. Primary care visits and antibiotic prescriptions account for the majority of expenditures. Key messages SRIRs and regional expenditures declined for simple and recurrent AOM after PCV13 introduction. Primary care visits and antibiotic prescriptions account for the majority of expenditures.

Background This study reports the incidence and prevalence of axial spondyloarthritis (axSpA) in the UK, and describes the baseline characteristics and comorbidities associated with the condition. Methods This study was conducted using the Clinical Practice Research Datalink, a large routine primary care database in the UK. Approximately 60% of contributing English primary care practices are linked to Hospital Episode Statistics (HES) secondary care data. AxSpA and relevant comorbidities were identified from Read or International Statistical Classification of Diseases and Related Health Problems-10 codes in primary care or HES datasets, respectively. The date of first axSpA diagnosis defined the index date. Patients with ≥90 days between practice registration and first axSpA diagnosis were classified as incident cases. The incidence and prevalence of axSpA were calculated annually from 2003-2017 for the UK as a whole, each constituent nation and English practices linked to HES data, to maximise case ascertainment. Comorbidities occurring prior to the index date (inclusive) were reported and compared with non-axSpA patients matched for age, sex, primary care practice and concurrent practice registration. Results Overall, 20,199 axSpA patients were identified, of whom 8,387 (41.5%) were classified as incident cases. Of the incident cases, 2,600 (31.0%) were female. Mean age at first diagnosis was 45.5 years (standard deviation [SD]: 17.2), mean body mass index was 27.2 kg/m2 (SD: 5.9) and 2,481 (29.6%) patients were current smokers. In 2017, the incidence of axSpA was 8.0 per 100,000 person-years and the prevalence was 15.8 per 10,000 population, an increase from 12.7 per 10,000 population in 2003. For patients from English practices linked to HES data, the incidence was 10.8 per 100,000 person-years and the prevalence was 17.5 per 10,000 population. 8,385 (∼100.0%) axSpA patients could be matched to non-axSpA controls. At baseline, all selected comorbidities were significantly increased in axSpA cases vs controls (Table). Conclusion This study reports an increasing prevalence of axSpA over the study period and higher rates of specific comorbidities in patients with axSpA vs matched controls. Caveats related to routine database studies, including secular changes in case ascertainment and observation bias, should be considered when interpreting these results. Disclosures C.L.I.

Background Pertussis affects people of all ages and can lead to severe complications in adults, including hospitalization. Pertussis immunity, whether vaccine-induced or from natural infection, wanes over time. Therefore, despite extensive pediatric vaccination against pertussis, adults remain susceptible to the disease. Here we present the reported incidence of pertussis in people ≥ 50 years old (≥ 50yo) in England and the United Kingdom (UK). Methods We performed an observational, retrospective database analysis using the UK Clinical Practice Research Datalink GOLD and Aurum primary care databases, and Hospital Episode Statistics database when available for English subjects (HES-Eng), 2009-2018. Occurrence of pertussis was identified by diagnostic codes recorded in primary care only for the UK subset, and primary care and/or secondary care for HES-Eng. Results In the ≥ 50yo UK population, a total of 47.1 million (m) person-years of follow-up (PYFU) including 28.5m PYFU for HES-Eng, were included. In the UK, the pertussis Incidence Rate (IR) across all years was 5.44 per 100,000 PYFU. Yearly IRs ranged from 0.79 – 11.40 per 100,000 PYFU and reflected the cyclic epidemiology of pertussis. A peak of IR was observed in 2012, known to be an outbreak year, and observed IRs were higher in 2013-2018 (4.75 – 9.73 per 100,000 PYFU) than 2009-2011 (0.79 – 1.48 per 100,000 PYFU). In the HES-Eng population, overall IR was 5.76 per 100,000 PYFU. IRs were highest in the younger age groups (HES-Eng: 8.88 in 50-54 yo; 1.42 in ≥ 85 yo) (see table 1 and 2). Table 1 Table 2 Conclusion The observed reported IR of pertussis was similar in the UK and HES-Eng populations, noting the inclusion of secondary care diagnoses in the latter. The dynamics of IRs across years are consistent with estimated IRs from Public Health England data. Considering the burden of pertussis established elsewhere in older adults, and their non-negligible contribution to the whole population incidence, strategies for the prevention of pertussis should include this age group.

Objectives To assess realized access and equity of access to three components of diabetes care – daily self-monitoring of blood glucose (SMBG), annual dilated eye examination and biannual glycosylated haemoglobin (HbA1c) testing – and to find the factors affecting adherence to these. Methods In this retrospective database analysis, data was obtained from the Behavioral Risk Factor Surveillance System survey. Andersen's behavioural model of health was used to determine the factors that might affect the utilization of the three components of diabetes care. Hierarchical logistic regression was used to determine equity of access to recommended diabetes care. Data analysis was performed using SAS version 9.2. Key findings Realized access was highest for biannual HbA1c testing, followed by annual dilated eye examination and daily SMBG. Enabling resources drove access to daily SMBG and annual HbA1c testing, while access to annual eye exams was driven by predisposing characteristics. Uninsured individuals and those who did not receive diabetes education were less likely to adhere to diabetes care. Conclusions Measures are needed to increase realized access and equity of access to recommended diabetes care.

Aims: To determine whether day and time of admission influences the practice patterns of the admitting general surgeon and subsequent outcomes for patients diagnosed with small bowel obstruction. Methods: A retrospective database review was carried out, covering patients admitted with the presumed diagnosis of partial small bowel obstruction from 2004–2011. Results: A total of 404 patients met the inclusion criteria. One hundred and thirty-nine were admitted during the day, 93 at night and 172 on the weekend. Overall 30.2% of the patients were managed operatively with no significant difference between the groups (P = 0.89); however, of patients taken to the operating room, patients admitted during the day received operative intervention over 24 hours earlier than those admitted at a weekend, 0.79 days vs 1.90 days, respectively (P = 0.05). Overall mortality was low at 1.7%, with no difference noted between the groups (P = 0.35). Likewise there was no difference in morbidity rates between the three groups (P = 0.90). Conclusions: Despite a faster time to operative intervention in those patients admitted during the day, our study revealed that time of admission does not appear to correlate to patient outcome or mortality.

BACKGROUND Glioblastoma (GBM) represents 14.9% of all primary brain tumors in the US with ≥12,000 new cases expected in 2017. Current management lacks any curative therapies and remains palliative through the use of surgery, postoperative radiotherapy and concurrent and adjuvant chemotherapy. This study compares guideline-recommended-care to current practice patterns in GBM patients treated in the community, which is largely unknown.
