OBJECTIVE:To examine the effect of autoimmune (AI) disease on the composite outcome of intensive care unit (ICU) admission, intubation, or death from COVID-19 in hospitalized patients. METHODS:Retrospective cohort study of 186 patients hospitalized with COVID-19 between March 1, 2020, and April 15, 2020 at NewYork-Presbyterian Hospital/Columbia University Irving Medical Center. The cohort included 62 patients with AI disease and 124 age- and sex-matched controls. The primary outcome was a composite of ICU admission, intubation, and death, with secondary outcome as time to in-hospital death. Baseline demographics, comorbidities, medications, vital signs, and laboratory values were collected. Conditional logistic regression and Cox proportional hazards regression were used to assess the association between AI disease and clinical outcomes. RESULTS:0.73, 95% CI 0.33-1.63). CONCLUSION:Among patients hospitalized with COVID-19, individuals with AI disease did not have an increased risk of a composite outcome of ICU admission, intubation, or death.

OBJECTIVE:To examine associations between sociodemographic and mental health characteristics with household risk for food insecurity during the COVID-19 outbreak. DESIGN/METHODS:Cross-sectional online survey analysed using univariable tests and a multivariable logistic regression model. SETTING/METHODS:The United States during the week of 30 March 2020. PARTICIPANTS/METHODS:A convenience sample of 1965 American adults using Amazon's Mechanical Turk platform. Participants reporting household food insecurity prior to the pandemic were excluded from analyses. RESULTS:One thousand two hundred and fifty participants reported household food security before the COVID-19 outbreak. Among this subset, 41 % were identified as at risk for food insecurity after COVID-19, 55 % were women and 73 % were white. On a multivariable analysis, race, income, relationship status, living situation, anxiety and depression were significantly associated with an incident risk for food insecurity. Black, Asian and Hispanic/Latino respondents, respondents with an annual income <$100 000 and those living with children or others were significantly more likely to be newly at risk for food insecurity. Individuals at risk for food insecurity were 2·60 (95 % CI 1·91, 3·55) times more likely to screen positively for anxiety and 1·71 (95 % CI 1·21, 2·42) times more likely to screen positively for depression. CONCLUSIONS:An increased risk for food insecurity during the COVID-19 pandemic is common, and certain populations are particularly vulnerable. There are strong associations between being at risk for food insecurity and anxiety/depression. Interventions to increase access to healthful foods, especially among minority and low-income individuals, and ease the socioemotional effects of the outbreak are crucial to relieving the economic stress of this pandemic.

OBJECTIVES:The Coronavirus disease 2019 (COVID-19) pandemic disrupted medical student education, particularly in New York City (NYC). We aimed to assess the impact of the COVID-19 pandemic on medical students' residency choices. METHODS:The authors conducted a cross-sectional survey of medical students in all years of study at four NYC medical schools (Columbia, Cornell, NYU, and SUNY Downstate). The survey was fielded from 19 Aug 2020 to 21 Sep 2020. Survey questions included items assessing COVID-19 impact on residency choices, personal impact of COVID-19, residency/specialty choices, and factors influencing these choices. RESULTS:A total of 2310 students received the survey, with 547 (23.7%) providing partial responses and 212 (9.2%) providing valid responses for our primary analysis. 59.0% of participants thought that COVID-19 influenced their choice of residency/specialty, with 0.9% saying the influence was to a great extent, 22.2% to some extent, and 35.8% very little. On multivariable analysis, factors that were independently associated with COVID-19 impacting residency choice included low debt ($1 to $99,999: adjOR 2.23, 95%CI 1.02-5.03) compared with no debt and Other race/ethnicity (adjOR 0.26, 95%CI 0.10-0.63) compared with White race/ethnicity. On secondary analysis of all participants answering survey items for logistic regression regardless of survey completion, direct personal impact of COVID-19 was significantly associated with COVID-19 impacting specialty choice (adjOR 1.90, 95%CI 1.04-3.52). Moreover, 24 students (11.6%) reported a change in their top residency choice from before to during/after COVID-19, citing concerns about frontline work, work-life balance, and risk of harm. CONCLUSIONS:Our study found that 3 in 5 (59.0%) participants felt that COVID-19 impacted their residency choice, with 11.6% of respondents explicitly changing their top specialty choice. Investigating the impact of the pandemic on medical student residency considerations is crucial to understand how medical career outlooks may change in the future.

BACKGROUND:Ileal pouch-anal anastomosis (IPAA) is the mainstay of surgical treatment for patients with ulcerative colitis (UC) but is associated with an increased risk of infertility. We developed a simulation model examining the impact of initial surgical procedure on quality-adjusted life-years (QALYs) and fertility end points. METHODS:A patient-level state transition model was used to analyze outcomes by surgical approach strategy for females of childbearing age. Initial surgical options included IPAA, rectal-sparing colectomy with end ileostomy (RCEI), and ileorectal anastomosis (IRA). The primary outcome examined was QALYs, whereas secondary outcomes included UC and fertility-associated end points. RESULTS:IPAA resulted in higher QALYs for patients aged 20-30 years, as compared with RCEI. For patients aged 35 years, RCEI resulted in higher QALYs (7.54 RCEI vs 7.53 IPAA) and was associated with a 28% higher rate of childbirth, a 14-month decrease in time to childbirth, and a 77% reduction in in vitro fertilization utilization. When accounting for the decreased infertility risk associated with laparoscopic IPAA, IPAA resulted in higher QALYs (7.57) even for patients aged 35 years. CONCLUSIONS:Despite an increased risk of infertility, our model results suggest that IPAA may be the optimal surgical strategy for female UC patients aged 20-30 years who desire children. For patients aged 35 years, RCEI should additionally be considered, as QALYs for RCEI and IPAA were similar. These quantitative data can be used by patients and providers to help develop an individualized approach to surgical management choice.

BACKGROUND:Despite increased risk of venous thromboembolism (VTE) among hospitalized patients with inflammatory bowel disease (IBD), pharmacologic prophylaxis rates remain low. We sought to understand the reasons for this by assessing factors associated with VTE prophylaxis in patients with IBD and the safety of its use. METHODS:This was a retrospective cohort study conducted among patients hospitalized between January 2013 and August 2018. The primary outcome was VTE prophylaxis, and exposures of interest included acute and chronic bleeding. Medical records were parsed electronically for covariables, and logistic regression was used to assess factors associated with VTE prophylaxis. RESULTS:There were 22,499 patients studied, including 474 (2%) with IBD. Patients with IBD were less likely to be placed on VTE prophylaxis (79% with IBD, 87% without IBD), particularly if hematochezia was present (57% with hematochezia, 86% without hematochezia). Among patients with IBD, admission to a medical service and hematochezia (adjusted odds ratio 0.27; 95% CI, 0.16-0.46) were among the strongest independent predictors of decreased VTE prophylaxis use. Neither hematochezia nor VTE prophylaxis was associated with increased blood transfusion rates or with a clinically significant decline in hemoglobin level during hospitalization. CONCLUSION:Hospitalized patients are less likely to be placed on VTE prophylaxis if they have IBD, and hematochezia may drive this. Hematochezia appeared to be minor and was unaffected by VTE prophylaxis. Education related to the safety of VTE prophylaxis in the setting of minor hematochezia may be a high-yield way to increase VTE prophylaxis rates in patients with IBD.

BACKGROUND & AIMS/OBJECTIVE:Guidelines recommend testing patients with peptic ulcer disease for Helicobacter pylori infection. We sought to identify factors associated with adherence to testing for H pylori in patients hospitalized for bleeding ulcers and to evaluate whether performing these tests affect risk for rebleeding. METHODS:We performed a retrospective study of 830 inpatients who underwent endoscopy from 2011 through 2016 for gastrointestinal bleeding from gastric or duodenal ulcers. We searched electronic medical records for evidence of tests to detect H pylori by biopsy, serologic, or stool antigen analyses. We used multivariable models to identify clinical, demographic, and endoscopic factors associated with testing for H pylori. Kaplan-Meier analysis was performed to determine whether H pylori testing altered risk for the composite outcome of rebleeding or death within 1 year of admission. RESULTS:Among the patients hospitalized for bleeding peptic ulcer disease during the 6-year period, 19% were not tested for H pylori within 60 days of index endoscopy. Hospitalization in the intensive care unit (ICU) was the factor most frequently associated with nonadherence to H pylori testing guidelines (only 66% of patients in the ICU were tested vs 90% of patients not in the ICU; P < .01), even after we adjusted for ulcer severity, coagulation status, extent of blood loss, and additional factors (adjusted odds ratio, 0.42; 95% CI, 0.27-0.66). Testing for H pylori was associated with a 51% decreased risk of rebleeding or death during the year after admission (adjusted hazard ratio 0.49; 95% CI, 0.36-0.67). CONCLUSIONS:In an analysis of hospitalized patients who underwent endoscopy for gastrointestinal bleeding from gastric or duodenal ulcers, we found admission to the ICU to be associated with failure to test for H pylori infection. Failure to test for H pylori was independently associated with increased risk of rebleeding or death within 1 year of hospital admission. We need strategies to increase testing for H pylori among inpatients with bleeding ulcers.

BACKGROUND & AIMS:Patients with inflammatory bowel diseases (IBDs) have a high risk of venous thromboembolism (VTE). We assessed the timing and risk factors associated with readmission to the hospital for VTE among patients with IBD. METHODS:We collected data from the Nationwide Readmissions Database on IBD index admissions resulting in readmission to the hospital for VTE within 60 days, from 2010 through 2014. We used univariable and multivariable regression to assess risk factors associated with VTE readmission with unadjusted risk ratio (RR) and adjusted RR (aRR) as measures of effect. Time to VTE readmission was assessed in 10-day intervals, for up to 90 days. RESULTS:We identified 872,122 index admissions of patients with IBD; 1160 resulted in readmission with VTE. More than 90% of readmissions occurred within 60 days of discharge from the index admission. Factors associated with hospital readmission with VTE included prior VTE, longer length of hospital stay, comorbidities, having a flexible sigmoidoscopy or colonoscopy at index admission, and age older than 18 years. Additional risk factors included Clostridium difficile infection at index admission (aRR, 1.47; 95% CI, 1.17-1.85) and discharge to a skilled nursing facility or intermediate care facility (aRR, 1.39; 95% CI, 1.14-1.70) or discharge with home health services (aRR, 1.65; 95% CI, 1.41-1.94). CONCLUSIONS:Among patients admitted to the hospital with IBD, most readmissions with VTE occur within 60 days of discharge. Readmission with VTE is associated with C difficile infection and discharge to a skilled nursing facility, intermediate care facility, or with home health services. Studies are needed to evaluate the potential benefit of extending VTE prophylaxis for patients admitted to the hospital with IBD for up to 2 months after discharge, to minimize risk.
