Background: Identifying patients at risk for mortality from COVID-19 is crucial to triage, clinical decision-making, and the allocation of scarce hospital resources. The 4C Mortality Score effectively predicts COVID-19 mortality, but it has not been validated in a United States (U.S.) population. The purpose of this study is to determine whether the 4C Mortality Score accurately predicts COVID-19 mortality in an urban U.S. adult inpatient population., Methods: This retrospective cohort study included adult patients admitted to a single-center, tertiary care hospital (Philadelphia, PA) with a positive SARS-CoV-2 PCR from 3/01/2020 to 6/06/2020. Variables were extracted through a combination of automated export and manual chart review. The outcome of interest was mortality during hospital admission or within 30 days of discharge., Results: This study included 426 patients; mean age was 64.4 years, 43.4% were female, and 54.5% self-identified as Black or African American. All-cause mortality was observed in 71 patients (16.7%). The area under the receiver operator characteristic curve of the 4C Mortality Score was 0.85 (95% confidence interval, 0.79-0.89)., Conclusions: Clinicians may use the 4C Mortality Score in an urban, majority Black, U.S. inpatient population. The derivation and validation cohorts were treated in the pre-vaccine era so the 4C Score may over-predict mortality in current patient populations. With stubbornly high inpatient mortality rates, however, the 4C Score remains one of the best tools available to date to inform thoughtful triage and treatment allocation., Competing Interests: Conflicts of Interest The authors have no conflicts of interest to disclose., (Copyright © 2022 Southern Society for Clinical Investigation.

Background: Patients with depression frequently seek care in the emergency department (ED), especially in the context of suicidal ideation (SI) and self-harm (SH). However, the prevalence and trends in the United States (US) of ED visits for depression have not yet been characterized using a nationally representative sample. This study evaluates ED trends for depression in the US from 2006 to 2014., Methods: Data was obtained from the Nationwide Emergency Department Sample (NEDS) in 2006 and 2014 using a primary ICD-9 diagnosis of depression or a primary diagnosis of suicidal ideation (SI) and a secondary diagnosis of depression., Results: Between 2006 and 2014, there was a 25.9% increase in visits to the ED for depression, which was higher than the 14.8% increase in total ED visits during this time period. The mean inflation adjusted charges associated with depression-related ED visits increased by 107.7%, which was higher than the increase in mean charges for all ED visits in the same time period (40.47%). Visit rates were bimodally distributed with respect to age, with peaks in adolescence and middle age. Notably there was a 61.3% increase in ED visits for depression in individuals younger than 20 between 2006 and 2014. Over half of patients were admitted for inpatient care with a mean length of stay of 5.6 days in both years. Inpatient charges increased 71.8% between 2006 and 2014., Conclusions: ED visits for depression in the United States rose 25.9% between 2006 and 2014, which was higher than the 14.8% increase in total ED visits during this time period. Over half of ED depression visits were admitted to inpatient stay (mean 5.6 days both years)., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Introduction: Diabetic individuals commonly report disordered bowel habits. This study aims to report the prevalence and associated factors of chronic diarrhea (CD) and chronic constipation (CC) in diabetics using a nationally representative sample of US adults., Methods: Analyses were performed using data from subjects in the 2009-2010 National Health and Nutrition Examination Survey (NHANES) dataset who completed the Bowel Health Questionnaire. The NHANES dataset provides medical comorbidities, demographics, and dietary habits of a nationally representative group of adult survey participants in the United States. CC and CD were defined by Bristol Stool Form Scale (BSFS) Types 1 & 2 and BSFS Types 6 & 7 as the "usual or most common stool type," respectively, and frequent laxative users were also defined as having CC. Co-variables for all subjects included demographic and lifestyle factors, and co-variables evaluated only in diabetics included treatment and severity markers for diabetes., Results: We identified 661 diabetic subjects and 4488 non-diabetic subjects. Diabetic subjects (25.8%) reported disordered bowel habits. In unadjusted analysis, CD was more prevalent in diabetics than in non-diabetics (11.2% vs. 6.0%; p < 0.0001); however, the prevalence of CC was not significantly different between groups (14.6% vs. 11.2%; p = 0.126). When adjusting for covariates (e.g., BMI, gender, age, race/ethnicity, education level, etc.), diabetes itself remained associated with CD. Diabetic individuals with CD more frequently used drugs to lower blood sugar, and diabetic subjects with CC more frequently had poor kidney function., Conclusions: CD is significantly more prevalent in diabetics than in non-diabetics, whereas CC is not, and the association between CD and diabetes remains significant when adjusting for covariates. Use of medications that lower blood sugar is associated with CD in diabetic individuals, whereas poor kidney function is associated with CC in diabetics.

Background & Aims: Fecal urgency is a common symptom among patients with gastrointestinal disorders, but can also occur in healthy individuals with normal bowel habits. There have been few studies of fecal urgency in the general population. We performed a cross-sectional analysis of data from the National Health and Nutrition Examination Survey (NHANES) to analyze the prevalence of and risk factors for this symptom., Methods: We analyzed data from 4676 persons who completed the Bowel Health Questionnaire from the NHANES, from 2009 through 2010. The NHANES sampled a nationally representative group of adults in the United States and provides information on demographics, medical comorbidities, and dietary habits of survey participants. The Bowel Health Questionnaire provided additional information about bowel symptoms such as urgency, incontinence, constipation, and diarrhea. We identified individuals with fecal urgency and calculated differences in fecal urgency among subgroups using chi-squared analysis. We used logistic regression to identify factors associated with urgency., Results: In our study population, the prevalence of fecal urgency was 3.3%; 29.5% of individuals with fecal urgency had diarrhea. The prevalence of fecal urgency was significantly higher in individuals who had diarrhea (14.8%) than in individuals without diarrhea (3.1%). Older age, female sex, poverty, urinary urge incontinence, diarrhea, and increased stool frequency were all associated with fecal urgency on multivariable analysis. Decreased fiber intake and increased carbohydrate intake were associated with urgency among individuals with diarrhea., Conclusions: In an analysis of data from 4676 individuals who completed a Bowel Health Questionnaire from the NHANES, we found a significantly higher proportion of individuals with diarrhea to have fecal urgency. However, most individuals with fecal urgency do not have diarrhea. Factors associated with fecal urgency vary among individuals with and without diarrhea., (Copyright © 2018 AGA Institute.

Objectives: No studies to date estimate the prevalence of chronic diarrhea in the United States using the Bristol stool form scale (BSFS). This study aims to report the prevalence and associated factors of chronic diarrhea using BSFS scores in a nationally representative sample of US adults., Methods: We identified 5,246 adult participants (age ≥20 years) who completed the bowel health questionnaire in the National Health and Nutrition Examination Survey 2009-2010 data set. Chronic diarrhea was defined as type 6 or 7 rating on the BSFS (mushy or liquid consistency) as the "usual or the most common stool type." Co-variables included age, race, education, poverty income ratio, body mass index, number of medications, feeling depressed, physical activity, and dietary intake. Prevalence estimates and prevalence odds ratios (PORs) were analyzed in adjusted multivariable models using appropriate sampling weights., Results: We found a prevalence of chronic diarrhea of 6.6% (95% confidence interval (CI) 5.8, 7.4) in the nationally representative data set. High daily carbohydrate intake (POR 1.56, 95% CI 1.02, 2.40), obesity (POR 2.04, 95% CI 1.44, 2.89), feeling depressed (POR 1.84, 95% CI 1.21, 2.80), older age (POR 1.02, 95% CI 1.01, 1.02), and female sex (POR 1.68, 95% CI 1.28, 2.21) were positively correlated with chronic diarrhea. Non-Hispanic White race (POR 0.49, 95% CI 0.29, 0.81) and higher education (POR 0.60, 95% CI 0.43, 0.83) were negatively correlated with chronic diarrhea., Conclusions: In a nationally representative sample of the US adults, the prevalence of chronic diarrhea was 6.6%. We identified demographic, lifestyle, and dietary factors associated with chronic diarrhea.

Objectives: Our current understanding of normal bowel patterns in the United States (US) is limited. Available studies have included individuals with both normal and abnormal bowel patterns, making it difficult to characterize normal bowel patterns in the US. The current study aims to (1) examine frequency and consistency in individuals with self-reported normal bowel habits and (2) determine demographic factors associated with self-reported normalcy., Methods: This study used data from adult participants who completed bowel health questions as part of the National Health and Nutrition Examination Survey (NHANES) in 2009-2010 and who reported normal bowel patterns (N=4,775). Data regarding self-perceived bowel health; stool frequency; stool consistency (using the Bristol Stool Form Scale (BSFS)); and demographic factors were analyzed., Results: 95.9% of the sample reported between 3 and 21 BMs per week. Among men, 90% reported a BSFS between 3 and 5, while for women it was 2-6. After controlling for age, the following demographic variables were associated with normalcy: male sex, higher education, higher income, <2 daily medications, and high daily fiber intake. Hispanic ethnicity was significantly associated with abnormal self-reported bowel habits., Conclusions: This is the first study to evaluate normal bowel frequency and consistency in a representative sample of adults in the US. The current findings bolster the common "3 and 3" metric of normal frequency (3 BMs/day to 3 BMs/week) while also suggesting different criteria for normal consistency for men and women. Finally, this study provides novel information about demographic factors associated with normal frequency and consistency.
