RESUMEN
Chronic spontaneous urticaria is defined as migratory evanescent pruritic blanching wheals that occur with variable frequency for 6 weeks or more, with or without accompanying angioedema. This condition affects approximately 0.1% to 1.4% of persons worldwide. Second-generation H1 antihistamines are the mainstay of management, with refractory cases often managed with an array of options, including H2 antihistamines, leukotriene receptor antagonists, glucocorticosteroids, immunosuppressive agents, and omalizumab. However, the degree of practice variation as to what treatments are prescribed is poorly understood, given that clinical care could be driven by patient preferences or lack of clarity as to best practices for refractory cases. We conducted a small, exploratory study of the role of race, ethnicity, and regional geographic distance to specialist care on chronic spontaneous urticaria prescribing practices. A small-area geographic variation in chronic spontaneous urticaria management in a large Chicago-area health care system was identified. Rates of omalizumab use varied by patient zip code, with more omalizumab prescriptions being associated with zip codes closer to the main office of an academic medical center-affiliated allergist-immunologist practice. Higher rates of omalizumab use were associated with White race in regional and patient-level analyses, though the reasons for this race-based finding are not clear.

CONTEXT: Birth cohort ("baby boomer") screening represents a well-validated strategy for the identification of asymptomatic hepatitis C-infected patients. However, successful linkage of newly diagnosed patients to antiviral therapy has been more difficult to accomplish. OBJECTIVE: To analyze the results of a systemwide birth cohort screening program in a US community health care system. DESIGN: We analyzed the data from an ongoing hepatitis C virus (HCV) screening and treatment program that was established at NorthShore University Health System in 2015. Hepatitis C virus screening by primary care providers was prompted through automated Best Practice and Health Maintenance alerts. Patient visits and screening orders were tracked using a customized HCV dashboard. Virologic, demographic, and treatment data were assessed and compared with those of a cohort of patients with previously established HCV infection. RESULTS: Since program inception, 61 8161 (64.3%) of the entire NorthShore baby boomer population of 96 001 patients have completed HCV antibody testing, and 160 patients (0.26%) were antibody positive. Of 152 antibody-positive patients who underwent HCV RNA testing, 53 (34.2%) were viremic. A total of 39 of 53 patients (73.6%) underwent antiviral therapy and achieved a sustained virologic response. Compared with patients identified through screening, a comparison cohort of patients with previously established HCV had more advanced fibrosis and significantly lower dropout rates. The COVID-19 pandemic was associated with a decrease in the number of outpatient visits of screening-eligible patients and with a reduction in HCV screening rates. CONCLUSION: Our data demonstrate the electronic medical records-assisted systemwide implementation of HCV birth cohort screening and successful linkage to antiviral therapy in a community-based US multihospital system.

The study aimed to assess the effect of an electronic medical record-embedded best practice alert (BPA) on HCV age cohort screening in primary care clinics. HCV testing by primary care physicians was monitored prior and subsequent to the implantation of the BPA. Four intervals of 9 months duration were analysed in detail, including a pre-BPA baseline analysis and three annual post-BPA assessments. Pre- and post-BPA orders consistently followed a power law distribution, characterized by small groups of physicians placing the majority of test orders. Significant correlations were present between the numbers of tests orders by each physician, suggesting that 'high' and 'low' screening performances tended to be physician-specific. Testing rates increased markedly in response to the BPA, resulting in completion of screening in 56.8% (50,468 of 88,914%) of the entire age cohort within less than 3 years. In conclusion, HCV age cohort testing by primary care physicians follows a power-law distribution, with high-performing physicians contributing disproportionately to the overall effort. A simple BPA resulted in a sufficient increase in testing to allow testing of the entire target population within a reasonable time frame.

BACKGROUND: Single nucleotide polymorphism (SNP)-based polygenic risk scoring is predictive of colorectal cancer (CRC) risk. However, few studies have investigated the association of genetic risk score (GRS) with detection of adenomatous polyps at screening colonoscopy. METHODS: We randomly selected 1769 Caucasian subjects who underwent screening colonoscopy from the Genomic Health Initiative (GHI), a biobank of NorthShore University HealthSystem. Outcomes from initial screening colonoscopy were recorded. Twenty-two CRC risk-associated SNPs were obtained from the Affymetrix™ SNP array and used to calculate an odds ratio (OR)-weighted and population-standardized GRS. Subjects with GRS of < 0.5, 0.5-1.5, and > 1.5 were categorized as low, average and elevated risk. RESULTS: Among 1,769 subjects, 520 (29%) had 1 or more adenomatous polyps. GRS was significantly higher in subjects with adenomatous polyps than those without; mean (95% confidence interval) was 1.02 (1.00-1.05) and 0.97 (0.95-0.99), respectively, p < 0.001. The association remained significant after adjusting for age, gender, body mass index, and family history, p < 0.001. The detection rate of adenomatous polyps was 10.8%, 29.0% and 39.7% in subjects with low, average and elevated GRS, respectively, p-trend < 0.001. Higher GRS was also associated with early age diagnosis of adenomatous polyps, p < 0.001. In contrast, positive family history was not associated with risk and age of adenomatous polyps. CONCLUSIONS: GRS was significantly associated with adenomatous polyps in subjects undergoing screening colonoscopy. This result may help in stratifying average risk patients and facilitating personalized colonoscopy screening strategies.

ST-segment elevation myocardial infarction (STEMI) is a significant source of morbidity and mortality. Despite guideline-driven management and increased awareness of social determinants of health, there are persistent disparities in diagnosis, management, and outcomes. The coronavirus disease 2019 (COVID-19) pandemic has greatly affected emergency department visitation, conditions and throughput. The aim of this study was to find any potential health disparities in patients who presented with STEMI during the COVID-19 pandemic by reviewing STEMI care data from April to September 2019 (pre-pandemic) and April to September 2020 (during the pandemic) for our hospital system. Patients with STEMI within 12 h of presentation were included in this study, and subdivided by age, gender, and race/ethnicity. We compared the turnaround times between emergency department arrival to intervention (electrocardiogram or catheterization) within the patient subgroups to find any notable differences. No statistically significant changes in turnaround times during either study period were found based on age, gender, or race/ethnicity for the STEMI interventions despite shifts in emergency department resources during the pandemic. This study helped assess the status quo in STEMI intervention for our health system and serves as a baseline for us to monitor gaps in care or areas of improvement. As healthcare systems institute new measures to promote equitable care, such as improving the accuracy of demographic data capture, establishing a baseline is an essential first step in evaluating the impact of these measures.
RESUMEN
INTRODUCTION: We assessed the influence of a best practice alert (BPA) embedded within the electronic medical record on improving hepatitis C virus (HCV) birth-cohort screening by primary care physicians (PCPs). METHODS: Screening by 155 PCPs was monitored during 2 consecutive 9-month periods before and after implementation of the BPA. All tests were reviewed to differentiate true screening from other testing indications. RESULTS: Of 155 PCPs, 131 placed screening orders before and after BPA. Twenty-two PCPs started testing after BPA (P = 0.02). The number of tests placed and screening rates per PCP increased from 16 to 84 and from 3.3% to 13.2%, respectively (P < 0.0001). Before BPA, most PCPs rarely ordered screening HCV tests, whereas a small group of physicians generated most tests, indicative of an underlying power-law distribution. After the BPA, a new group of high-performing PCPs emerged, whose screening patterns were again characterized by a power-law distribution. However, pre-BPA test rates of individual PCPs were not predictive of their post-BPA rates. Overall, the introduction of the BPA narrowed the gap between low- and high-performing testers, indicating that modest increases in testing by a large number of low-performing PCPs could drive substantial improvement in program implementation. DISCUSSION: HCV birth-cohort screening by PCPs was shaped by an underlying power-law distribution. This distribution was preserved after the implementation of a BPA, although pre-BPA test rates were not predictive of post-BPA rates. Increases in test rates by high- and low-performing PCPs both contributed to the overall success of the BPA.
