    Identification of Bias in Ordering Further Imaging in Ethnic Groups With Indeterminate Ultrasound for Appendicitis
    (Springer Nature, 2022-08-17) Desai, Puja; Haut, Lindsey; Wagers, Brian; Coffee, R. Lane, Jr.; Kelker, Heather; Wyderko, Michael; Sarmiento, Elisa J.; Kanis, Jessica; Emergency Medicine, School of Medicine
    Background: Recent studies have shown a higher incidence of complications from acute appendicitis in Hispanic populations. Hispanic ethnicity alone has been shown to be a risk factor. In contrast, one study found little evidence of racial disparities in complication rates. The objective of this study was to identify physician bias regarding whether ethnicity drives further testing after initial radiologic imaging has been obtained in the evaluation of appendicitis in our pediatric emergency department (PED). The use of computed tomography (CT) scan in the diagnosis of appendicitis was compared between Hispanic versus non-Hispanic populations when ultrasound (US) was indeterminate. Methodology: This is a retrospective cohort study of Hispanic and non-Hispanic patients aged 2-18 who presented to the PED with right lower quadrant abdominal pain over a one-year period (January 1, 2017 to December 29, 2017). Both groups were subdivided into positive, negative, or indeterminate US findings for appendicitis. Each subgroup was analyzed based on those who had CT imaging done. Results: A total of 471 ultrasounds were performed, 162 Hispanic and 309 non-Hispanic patients. Indeterminate US scans were documented in 90/162 (56%) Hispanic versus 155/309 (50%) non-Hispanic patients. Of those with indeterminate US scans, 30% Hispanic versus 32% non-Hispanic patients received CT scans. Negative US scans were documented in 54/162 (33%) Hispanic versus 102/309 (33%) non-Hispanic patients. Of those with negative US scans, 7% Hispanic versus 5% non-Hispanic patients received CT scans. Chi-square analysis comparing both the proportion of CT scans received for indeterminate US scans (p=0.71) and negative US scans (p=0.52) showed no statistical significance. Conclusions: There was no significant difference in the number of CT scans ordered for indeterminate US scans between Hispanic and non-Hispanic patients. One can infer that there is no inherent bias toward ordering advanced imaging in Hispanic children based on ethnicity alone.

    Non-response Bias in Social Risk Factor Screening Among Adult Emergency Department Patients
    (Springer, 2023-07-22) Vest, Joshua R.; Mazurenko, Olena; Health Policy and Management, Richard M. Fairbanks School of Public Health
    Healthcare organizations increasingly use screening questionnaires to assess patients' social factors, but non-response may contribute to selection bias. This study assessed differences between respondents and those refusing participation in a social factor screening. We used a cross-sectional approach with logistic regression models to measure the association between subject characteristics and social factor screening questionnaire participation. The study subjects were patients from a mid-western state safety-net hospital's emergency department. Subjects' inclusion criteria were: (1) ≥ 18 years old, (2) spoke English or Spanish, and (3) able to complete a self-administered questionnaire. We classified subjects that consented and answered the screening questionnaire in full as respondents. All others were non-respondents. Using natural language processing, we linked all subjects' participation status to demographic characteristics, clinical data, an area-level deprivation measure, and social risk factors extracted from clinical notes. We found that nearly 6 out of every 10 subjects approached (59.9%), consented, and completed the questionnaire. Subjects with prior documentation of financial insecurity were 22% less likely to respond to the screening questionnaire (marginal effect = -22.40; 95% confidence interval (CI) = -41.16, -3.63; p = 0.019). No other factors were significantly associated with response. This study uniquely contributes to the growing social determinants of health literature by confirming that selection bias may exist within social factor screening practices and research studies.

    Parents of healthy children assign lower quality of life measure to scenarios labeled as cancer than to identical scenarios not labeled as cancer
    (BMC, 2019-02-21) McElderry, Brenna M.; Mueller, Emily L.; Garcia, Abigail; Carroll, Aaron E.; Bennett, William E., Jr.; Medicine, School of Medicine
    BACKGROUND: While it is commonly understood that a cancer diagnosis evokes feelings of fear, the effect of labeling a child's illness as "cancer" remains unstudied. We hypothesized that lower health utility scores would be assigned to disease states labeled as cancer compared to identical disease states without the mention of cancer. METHODS: In this randomized study, caregivers of healthy children were asked to assign health utility values to different scenarios written as improving, stable, or worsening. Participants from general pediatric clinics at Eskenazi Health were randomly assigned to either the scenarios labeled as "cancer" or "a serious illness". Participants then rated the scenarios using the Standard Gamble, with laddering of health utilities between 0 (a painless death) and 1 (perfect health). We also gathered subject demographics and assessed the subject's numeracy. RESULTS: We approached 319 subjects and 167 completed the study. Overall median health utilities of "cancer" scenarios were lower than "serious illness" scenarios (0.61 vs. 0.72, p = 0.018). Multivariate regression (with an outcome of having a utility above the 75th percentile) showed no significant effects by race, ethnicity, numeracy, or income level. "Cancer" scenarios remained significantly lower after adjustment for confounders using logistic regression, but only for the more serious scenarios (OR 0.92, p = 0.048). CONCLUSIONS: On average, caregivers with healthy children were shown to take more risk with their treatment options and view their child as having a worse quality of life when they knew the disease was cancer. Awareness of this bias is important when discussing treatments with families, particularly when a risk of cancer is present.

    Race and Gender-Based Perceptions of Older Septuagenarian Adults
    (Mary Ann Liebert, 2022-11-14) Melton, Forest; Palmer, Kelly; Solola, Sade; Luy, Luis; Herrera-Theut, Kathryn; Zabala, Leanne; Knapp, Shannon M.; Yee, Ryan; Yee, Erika; Calhoun, Elizabeth; Thomas Hebdon, Megan C.; Pool, Natalie; Sweitzer, Nancy; Breathett, Khadijah; Medicine, School of Medicine
    Objectives: Older adults face racism, sexism, and ageism. As the U.S. population ages, it is important to understand how the current population views older adults. Methods: Participants recruited through Amazon's Mechanical Turk provided perceptions of older Black and White models' photographs. Using mixed-effect models, we assessed interactions between race and gender of participants and models. Results: Among Participants of Color and White participants (n = 712, 70% non-Hispanic White, 70% women, mean 37.81 years), Black models were perceived as more attractive, less threatening, and sadder than White models, but differences were greater for White participants (race-by-race interaction: attractive p = 0.003, threatening p = 0.009, sad p = 0.016). Each gender perceived their respective gender as more attractive (gender-by-gender interaction p < 0.0001). Male and female participants perceived male models as happier than female models, but differences were greater for male participants (p = 0.026). Irrespective of participant age group, women were perceived as more threatening (p = 0.012). Other perceptions were not significant. Discussion: Participants had few biases toward older Black and White models, while gender biases favored men.

    A Survey of Internal Medicine Residents: Their Learning Environments, Bias and Discrimination Experiences, and Their Support Structures
    (Dovepress, 2021-06-23) Sotto-Santiago, Sylk; Mac, Jacqueline; Slaven, James; Maldonado, Maria; Medicine, School of Medicine
    Purpose: While there is an emerging body of literature that demonstrates how racism and bias negatively impact the experiences of physicians and trainees from underrepresented groups in medicine in the US, little is known about the experiences of internal medicine trainees and their learning environments. The purpose of this study was to examine these learning environments and explore trainees' perceptions of race/ethnicity-related topics. Methods: A 35-item confidential electronic survey was disseminated to trainees from 11 internal medicine training programs in the US. A total of 142 trainees participated. Purposive sampling ensured alignment with 2018 IM trainee demographics by sex, race and ethnicity. Analyses were performed including chi-square, Fisher's exact tests, and logistic regression. Results: Key findings reveal 63% of respondents perceived disparities in the care provided to diverse patients. Two in three respondents were confident that their institution would respond to discrimination, but only 1/3 of respondents perceived appropriate reporting mechanisms. Black/African American trainees reported needing to minimize aspects of their race and were less likely to perceive their institutions as being supportive to people of color. Conclusion: Access to timely information about trainees' experiences with discrimination and bias in graduate medical education is imperative to disrupt systemic racism and health inequities. Findings suggest a perceived difference in health care provided to minoritized groups, a gap in formal mechanisms for reporting racism and discrimination experienced by trainees, and environments that challenge a sense of belonging. Findings add to current literature exposing the experience of underrepresented trainees in the US.
