RESUMO
OBJECTIVES: A major strategy to reduce the impact of breast cancer (BC) among African Americans (AA) is patient navigation, defined here as individualized assistance for reducing barriers to healthcare use. The primary focus of this study was to estimate the added value of incorporating breast health promotion by navigated participants and the subsequent BC screenings that network members may obtain. METHODS: In this study, we compared the cost-effectiveness of navigation across 2 scenarios. First, we examine the effect of navigation on AA participants (scenario 1). Second, we examine the effect of navigation on AA participants and their networks (scenario 2). We leverage data from multiple studies in South Chicago. Our primary outcome (BC screening) is intermediate, given limited available quantitative data on the long-term benefits of BC screening for AA populations. RESULTS: When considering participant effects alone (scenario 1), the incremental cost-effectiveness ratio was $3845 per additional screening mammogram. When including participant and network effects (scenario 2), the incremental cost-effectiveness ratio was $1098 per additional screening mammogram. CONCLUSION: Our findings suggest that inclusion of network effects can contribute to a more precise, comprehensive assessment of interventions for underserved communities.

BACKGROUND: Patient navigation is an increasingly widespread intervention to address the persistent, severe, and disproportionate breast cancer (BC) burden that African Americans (AA) face. Navigation may have more widespread effects than previously estimated due to patient-driven diffusion of BC information. METHODS: This pilot study examined the network effects of a randomized controlled trial via recruitment of navigated and non-navigated AA BC patients as well as their network members. We estimated study arm differences in patient BC promotion (i.e., number of individuals to whom BC patients promote BC screening) and network BC screening (i.e., % BC screening among network members). RESULTS: Among our sample of 100 AA BC patients, navigated patients promoted BC screening to more individuals than non-navigated patients. BC patients were more likely to promote BC screening to children and individuals with whom they communicated more frequently. Some models further suggested more network BC screening among "navigated" network members relative to "non-navigated" network members. CONCLUSIONS: Navigated AA patients promoted BC screening more widely throughout their networks than non-navigated AA BC patients. There were also suggestive findings regarding increased BC screening among their network members. Our pilot study highlights the potential for social network analysis to improve the precision of intervention effect estimates and to inform future innovations (e.g., integrating navigation and network-based interventions) with multilevel effects on cancer health disparities.

PURPOSE: Social support improves several quality of life (QOL) domains among African American breast cancer survivors. How different dimensions of social support are associated with QOL among African American breast cancer survivors may however differ from other populations. This study explores this hypothesis by examining associations of positive social support (supportive interactions that promote affection) and negative social support (non-supportive interactions wherein the provider of support may not have the best intended actions) with QOL among Chicago-based African American breast cancer survivors. METHODS: Study participants were eligible if they (1) were identified as being an African American female, (2) were at least 18 years of age or older, and (3) were diagnosed with breast cancer during or after navigation was implemented at the study hospital. Participants completed validated questionnaires via telephone or in-person interviews. RESULTS: Among our sample of 100 participants, positive support was associated with greater mental well-being in non-imputed (Std ß=1.60, CI: 0.51, 2.69, p= 0.004) and imputed models (Std ß= 1.67, CI: 0.68, 2.73, p=0.001). There was also a weaker inverse association with negative support and mental well-being when using non-imputed data (Std ß=-0.82, CI:-1.65, 0.02, p= 0.05). CONCLUSIONS: Our findings suggest that positive support, in particular, is highly influential for improving mental well-being among African American breast cancer survivors. Simultaneously, negative support appears to be an independent, albeit weaker, determinant of mental well-being.

Background: Studies show that patients want to engage in cost-of-care conversations and factor costs into the formulation of care plans. Low-income patients are particularly likely to defer care because of costs, suggesting that cost-of-care conversations may be an important factor in health equity. Little guidance is available to clinicians and health systems for how to integrate effective cost-of-care conversations into clinical practice or to address specific cost needs of low-income patients. Objective: To develop a framework and tool to assist cost-of-care conversations with low-income patients during prenatal care. Design: A qualitative study using human-centered design methods. Setting: University medical center-based obstetrics-gynecology (ob-gyn) practice. Participants: 20 pregnant or recently postpartum women, 16 clinicians, and 8 support and executive staff. Results: Pregnant women accumulate substantial indirect costs that interfere with treatment adherence and stress patients and their relationships. Frequency and duration of appointments are primary drivers of indirect costs; the burden is exacerbated by not knowing these costs in advance and disproportionately affects low-income patients. Working with ob-gyn clinicians, staff, and patients, a paper-based tool was developed to help patients forecast treatment demands and indirect costs, and to help clinicians introduce and standardize cost conversations. Limitations: Data were collected from a small number of stakeholders in a single clinical setting that may not be generalizable to other settings. The tool has not been tested for effects on adherence or clinical outcomes. Conclusion: A communication tool that helps pregnant patients understand their care plan and anticipate indirect costs can promote cost-of-care conversations between clinicians and low-income patients.

This paper examines the epidemiology of nonfatal firearm violence (NFFV) on the Westside of Chicago over three finite time periods: 2005-2008, 2009-2012, and 2013-2016. The trend analysis will look at any significant changes over the time periods and describe the demographic characteristics of NFFV. A descriptive analysis of Mount Sinai Hospital (MSH) Emergency Department (ED) data was conducted. NFFV patients were identified by specific firearm ICD-9 primary eCode injury categories: accident, assault, legal intervention, undetermined intent, suicide or self-inflicted injury, and legal intervention. The Pearson Chi-square test was conducted to statistically compare the categorical frequencies of the Chicago metropolitan region of injury, cause of firearm related injury, and place of injury by time period. There were a total of 3962 nonfatal hospitalizations at MSH between the three time periods due to gun violence related injuries. Overall, nonfatal hospitalizations were most frequent for those between age groups 16-24 (52.5%). The number of nonfatal hospitalizations decreased with increasing age for the age groups 35-44 (9.7%), 45-54 (3.2%), and > 54 (1.2%). There were significantly more nonfatal hospitalizations in males (n = 3649) than females (n = 312) across the three time periods. However, there was a 74.7% increase in female nonfatal hospitalizations from 2009-2012 to 2013-2016. There were significant racial differences in nonfatal hospitalizations between the three time periods. NFFV continues to be problem on the Westside of Chicago, particularly for young, Black men. The incidence of gun violence however has not changed significantly between 2005 and 2016.

OBJECTIVE: To assess the association between pancreatic enzyme replacement therapy (PERT) and resource utilization among patients with chronic pancreatitis (CP) in a large Midwestern US healthcare system. METHODS: This retrospective cohort study used electronic medical record data. Eligible patients (N = 2445) were aged ≥18 years and diagnosed with non-cystic fibrosis CP between January 2005 and December 2018, with ≥6 months' follow-up; study initiation was first encounter with the healthcare system. Patients in the PERT group were prescribed PERT at ≥1 encounter; patients in the non-PERT group were not prescribed PERT at any encounter. RESULTS: In total, 62,899 encounters were reviewed (PERT, n = 22,935; non-PERT, n = 39,964). More patients in the PERT group were younger, male, White, married/partnered and with private insurance than those in the non-PERT group. They also received longer care and had more overall encounters, fewer outpatient and day surgery/24-hour observation encounters, and more inpatient encounters. Emergency room encounters were similar between groups. Average cost by encounter was similar between groups ($225 and $213, respectively). CONCLUSIONS: Despite similar average costs per encounter, the groups had very different encounter types. More inferential research on PERT use among patients with CP is needed, particularly regarding resource utilization and long-term outcomes.

Schizophrenia is often characterized by recurring relapses, which are associated with a substantial clinical and economic burden. Early identification of individuals at the highest risk for relapse in real-world treatment settings could help improve outcomes and reduce healthcare costs. Prior work has identified a few consistent predictors of relapse in schizophrenia, however, studies to date have been limited to insurance claims data or small patient populations. Thus, this study used a large sample of health systems electronic health record (EHR) data to analyze relationships between patient-level factors and relapse and model a set of factors that can be used to identify the increased prevalence of relapse, a severe and preventable reality of schizophrenia. This retrospective, observational cohort study utilized EHR data extracted from the largest Midwestern U.S. non-profit healthcare system to identify predictors of relapse. The study included patients with a diagnosis of schizophrenia (ICD-10 F20) or schizoaffective disorder (ICD-10 F25) who were treated within the system between October 15, 2016, and December 31, 2021, and received care for at least 12 months. A relapse episode was defined as an emergency room or inpatient encounter with a pre-determined behavioral health-related ICD code. Patients' baseline characteristics, comorbidities and healthcare utilization were described. Modified log-Poisson regression (i.e. log Poisson regression with a robust variance estimation) analyses were utilized to estimate the prevalence of relapse across patient characteristics, comorbidities and healthcare utilization and to ultimately identify an adjusted model predicting relapse. Among the 8119 unique patients included in the study, 2478 (30.52%) experienced relapse and 5641 (69.48%) experienced no relapse. Patients were primarily male (54.72%), White Non-Hispanic or Latino (54.23%), with Medicare insurance (51.40%), and had baseline diagnoses of substance use (19.24%), overweight/obesity/weight gain (13.06%), extrapyramidal symptoms (48.00%), lipid metabolism disorder (30.66%), hypertension (26.85%), and diabetes (19.08%). Many differences in patient characteristics, baseline comorbidities, and utilization were revealed between patients who relapsed and patients who did not relapse. Through model building, the final adjusted model with all significant predictors of relapse included the following variables: insurance, age, race/ethnicity, substance use diagnosis, extrapyramidal symptoms, number of emergency room encounters, behavioral health inpatient encounters, prior relapses episodes, and long-acting injectable prescriptions written. Prevention of relapse is a priority in schizophrenia care. Challenges related to historical health record data have limited the knowledge of real-world predictors of relapse. This study offers a set of variables that could conceivably be used to construct algorithms or models to proactively monitor demographic, comorbidity, medication, and healthcare utilization parameters which place patients at risk for relapse and to modify approaches to care to avoid future relapse.
RESUMO
Background: Representativeness in clinical trials (CT) serves as a metric of access to healthcare and reflects differences that may determine differential efficacy of medical interventions; thus, quantifying representativeness in CT participation is critical. Methods: This retrospective, descriptive study utilized patient demographic data extracted from the largest Midwestern non-profit healthcare system. Using data between January 1, 2019 and December 31, 2021, a CT Participant Sample of 4,537 system patients who were active CT participants was compared to a CT Patient Population of 195,726 system patients receiving care by the PI of active CTs, which represented the target population. Chi-square goodness-of-fit tests were used to test differences in distributions of demographic variables between groups, indicating disparity in CT participation. Two metrics adapted from literature - participation incidence disparity (PID) and participation incidence ratio (PIR) - were calculated to quantify absolute and relative disparity in representativeness proportions, respectively. Descriptive approaches to assessing representativeness are also provided. Results: Results showed significant differences by race/ethnicity (χ2 = 50.64; p < 0.0001), age categories (χ2 = 56.64; p < 0.0001), and insurance (χ2 = 41.29; p < 0.0001). PID and PIR metrics revealed reduced CT participation among non-White racial/ethnic groups and increased CT participation among White Non-Hispanic patients. Further, CT participants ≥80 or Worker's Compensation were underrepresented while those with Self-Pay insurance were overrepresented as CT participants. Conclusions: Despite progress, continued efforts to not only enroll participants into CTs that are representative of the healthcare system and region, but also to better assess representativeness quantitatively are still needed.
RESUMO
Background: The lack of racial and ethnic diversity in clinical trials leads to skewed findings, limited generalizability, inequitable health outcomes for people of color, and insufficient access to innovative therapies. Our objective was to compare perceptions of barriers to participation in trials for people of color and trial staff to provide tangible solutions for improving diversity among study participants. Methods: This mixed method study utilized semi-structured interviews and surveys to evaluate barriers to participation and solutions to improve racial and ethnic diversity in clinical trials among healthcare system trial staff and community members from the same region. Through thematic analysis via coded transcripts and quantitative analysis via survey data, social support theory constructs were identified to evaluate where perceptions of barriers and solutions overlap and where they diverge. Results: A total of 55 trial staff and 75 community members participated in the study. Trial staff identified logistics and patients' unwillingness to receive additional treatments as perceived barriers to participation, while community members stated lack of information and lack of trust in their care team. Both groups identified hesitance toward research as a prominent barrier. Solutions related to informational support demonstrated the most overlap between groups, while instrumental support showed the most discordance. Conclusion: Solutions for improving racial and ethnic diversity in clinical trial participation are multi-faceted and have various levels of impact. Overlap and discordance of opinions regarding solutions should be further evaluated, and implementation of solutions should be carefully considered.
RESUMO
OBJECTIVE: To describe patient differences by prenatal care (PNC) model and identify factors that interact with race to predict more attended prenatal appointments, a key component of PNC adherence. METHODS: This retrospective cohort study used administrative data targeting prenatal patient utilization from two OB clinics with different care models (resident vs. attending OB) from within one large midwestern healthcare system. All appointment data among patients receiving prenatal care at either clinic between September 2, 2020, and December 31, 2021, were extracted. Multivariable linear regression was performed to identify predictors of attended appointments within the resident clinic, as moderated by race (Black vs. White). RESULTS: A total of 1034 prenatal patients were included: 653 (63%) served by the resident clinic (appointments = 7822) and 381 (38%) by the attending clinic (appointments = 4627). Patients were significantly different across insurance, race/ethnicity, partner status, and age between clinics (p < 0.0001). Despite prenatal patients at both clinics being scheduled for approximately the same number of appointments, resident clinic patients attended 1.13 (0.51, 1.74) fewer appointments (p = 0.0004). The number of attended appointments was predicted by insurance in crude analysis (ß = 2.14, p < 0.0001), with effect modification by race (Black vs. White) in final fitted analysis. Black patients with public insurance attended 2.04 fewer appointments than White patients with public insurance (7.60 vs. 9.64) and Black non-Hispanic patients with private insurance attended 1.65 more appointments than White non-Hispanic or Latino patients with private insurance (7.21 vs. 5.56). CONCLUSION: Our study highlights the potential reality that the resident care model, with more care delivery challenges, may be underserving patients who are inherently more vulnerable to PNC non-adherence at care onset. Our findings show that patients attend more appointments at the resident clinic if publicly insured, but less so if they are Black than White.
RESUMO
Objective: The objective of the CONTINUE study is to gather preliminary data on the potential impact of implementing a "Cost Tool" in routine obstetrics (OB) care. It is hypothesized that by providing prenatal patients with an ability to forecast their care plan, they would be better able to anticipate and plan for the costs associated with their prenatal care. Methods: Pilot data from interviews and surveys were collected from 71 prenatal patients across three clinics throughout Chicago, IL. Results: As compared to privately insured prenatal patients, prenatal patients with public insurance reported the most benefit in Cost Tool use. Specifically, that the Cost Tool helped to navigate insurance more effectively (OR 4.49, p=0.0254), see the "Big Picture" and link it to the family budget (OR 4.25, p=0.0099), and make the financial tradeoffs needed to get through pregnancy (OR 5.50, p=0.0305). Conclusion: The CONTINUE study provides preliminary signals of the Cost Tool's potential to help publicly insured prenatal patients better navigate the costs associated with their care plan. Innovations: The CONTINUE study contributes valuable preliminary data about the utility of a cost tool in routine OB care, especially as it may benefit low-income prenatal patients navigate prenatal care better.
RESUMO
The objective of the CONTINUE (conversations in routine OB care) pilot study was to gather preliminary data on the benefits of integrating a well-designed pregnancy support tool ("CONTINUE Tool") in low-income prenatal care. A total of 184 tools were distributed by 21 OB providers during the study implementation period. Follow-up data were collected from 71 (38.5%) prenatal patients across three community-based midwestern OB clinics serving a diverse prenatal patient population. Early-gestation prenatal patients received the strategically designed CONTINUE Tool during routine prenatal care and later completed a semi-structured interview or electronic survey to report pre-determined individual benefit items experienced due to tool usage. Factor analysis used individual benefit items to identify factors representing common underlying benefits ("factor benefits"). Logistic regression analyses were performed to describe the relative odds of participants with low income (public insurance) experiencing individual and factor benefits of tool use compared to participants of higher income (private insurance). Chi square tests (or Fisher's exact tests) were performed to generate P values reflecting statistically significant differences by income group. More low-income prenatal participants reported experiencing individual benefits as compared to higher-income participants. Among factor benefits, low-income participants were statistically more likely to report experiencing a time-related logistics benefit (OR = 4.00; 95% CI 1.02-15.73; P = .045). Low-income participants reported experiencing an overall logistics factor benefit (OR = 4.29; 95% CI 0.47-38.75), including a cost-related logistics benefit (OR = 3.08; CI 0.59-16.00), as well as an understanding benefit (OR = 1.90; 95% CI 0.72-5.04) and a self-efficacy benefit (OR = 1.30; 95% CI 0.44-3.87). While this study is limited by sample size due to being a pilot study, the findings suggest there may be tangible benefits to introducing the CONTINUE Tool among low-income prenatal patients. Given the staggering inequity in OB care and subsequent health outcomes, any preliminary findings on ways to help combat this are necessary and should lay the groundwork for subsequent randomized trials. Our preliminary findings show that supplementing routine OB care with the CONTINUE Tool can confer benefits to both providers and patients, but particularly for low-income prenatal patients who tend to have more structural barriers to adequate care in the first place.

Objectives: The objective of this study is to explore the characteristics of the subset of patients with hematologic malignancies (HMs) who had little to no change in SARS-CoV-2 spike antibody index value levels after a third mRNA vaccine dose (3V) and to compare the cohort of patients who did and did not seroconvert post-3V to get a better understanding of the demographics and potential drivers of serostatus. Study design: This retrospective cohort study analyzed SARS-CoV-2 spike IgG antibody index values pre and post the 3V data on 625 patients diagnosed with HM across a large Midwestern United States healthcare system between 31 October 2019 and 31 January 2022. Methods: To assess the association between individual characteristics and seroconversion status, patients were placed into two groups based on IgG antibody status pre and post the 3V dose, (-/+) and (-/-). Odds ratios were used as measures of association for all categorical variables. Logistic regressions were used to measure the association between HM condition and seroconversion. Results: HM diagnosis was significantly associated with seroconversion status (P = 0.0003) with patients non-Hodgkin lymphoma six times the odds of not seroconverting compared with multiple myeloma patients (P = 0.0010). Among the participants who were seronegative prior to 3V, 149 (55.6%) seroconverted after the 3V dose and 119 (44.4%) did not. Conclusion: This study focuses on an important subset of patients with HM who are not seroconverting after the COVID mRNA 3V. This gain in scientific knowledge is needed for clinicians to target and counsel these vulnerable patients.
RESUMO
OBJECTIVE: The aim of the study is to identify factors associated with breakthrough infection among a cohort of Midwestern healthcare personnel (HCP). METHODS: SARS-CoV-2-positive test results between March 1, 2020, and July 31, 2021, were collected from electronic medical records of HCP to identify breakthrough infections. RESULTS: Healthcare personnel who were younger than 35 years, received the Pfizer vaccine, and worked in COVID clinical units had greater adjusted odds of breakthrough infection. COVID infection before full vaccination was associated with reduced odds of breakthrough infection. CONCLUSIONS: Our study concluded that the most vulnerable HCP are younger, working in COVID-19 clinical units, and received Pfizer-BioNTech primary series vaccines. Healthcare personnel who had COVID before vaccination were at reduced risk of breakthrough infection, indicating that supplemental immunity could better protect at-risk HCP groups.

Given the overwhelming worldwide rate of infection and the disappointing pace of vaccination, addressing reinfection is critical. Understanding reinfection, including longevity after natural infection, will allow us to better know the prospect of herd immunity, which hinges on the assumption that natural infection generates sufficient, protective immunity. The primary objective of this observational cohort study is to establish the incidence of reinfection of COVID-19 among healthcare employees who experienced a prior COVID-19 infection over a 10-month period. Of 2,625 participants who experienced at least one COVID-19 infection during the 10-month study period, 156 (5.94%) experienced reinfection and 540 (20.57%) experienced recurrence after prior infection. Median days were 126.50 (105.50-171.00) to reinfection and 31.50 (10.00-72.00) to recurrence. Incidence rate of COVID-19 reinfection was 0.35 cases per 1,000 person-days, with participants working in COVID-clinical and clinical units experiencing 3.77 and 3.57 times, respectively, greater risk of reinfection relative to those working in non-clinical units. Incidence rate of COVID-19 recurrence was 1.47 cases per 1,000 person-days. This study supports the consensus that COVID-19 reinfection, defined as subsequent infection ≥ 90 days after prior infection, is rare, even among a sample of healthcare workers with frequent exposure.

Findings from a recent study of the largest documented cohort of individuals with Down syndrome (DS) in the United States described prevalence of common disease conditions and strongly suggested significant disparity in mental health conditions among these individuals as compared with age- and sex-matched individuals without DS. The retrospective, descriptive study reported herein is a follow-up to document prevalence of 58 mental health conditions across 28 years of data from 6078 individuals with DS and 30,326 age- and sex-matched controls. Patient data were abstracted from electronic medical records within a large integrated health system. In general, individuals with DS had higher prevalence of mood disorders (including depression); anxiety disorders (including obsessive-compulsive disorder); schizophrenia; psychosis (including hallucinations); pseudobulbar affect; personality disorder; dementia (including Alzheimer's disease); mental disorder due to physiologic causes; conduct disorder; tic disorder; and impulse control disorder. Conversely, the DS cohort experienced lower prevalence of bipolar I disorder; generalized anxiety, panic, phobic, and posttraumatic stress disorders; substance use disorders (including alcohol, opioid, cannabis, cocaine, and nicotine disorders); and attention-deficit/hyperactivity disorder. Prevalence of many mental health conditions in the setting of DS vastly differs from comparable individuals without DS. These findings delineate a heretofore unclear jumping-off point for ongoing research.
RESUMO
A recent disease prevalence study of the largest documented Down syndrome (DS) cohort in the United States strongly suggested significant disparity in general infectious disease conditions among individuals with DS versus those without DS. In this follow-up retrospective analysis, we explored these differences in greater detail by calculating prevalence of 52 infectious diseases, across 28 years of data among 6078 individuals with DS and 30,326 age- and sex-matched controls, abstracted from electronic medical records within a large Midwestern health system. We found that the DS cohort had higher prevalence of pneumonias (including aspiration, viral, bacterial, pneumococcal, and unspecified/atypical); otitis externa; and the skin infections impetigo, abscess, and cellulitis. To the contrary, the DS cohort had lower prevalence of many respiratory infections other than pneumonia (including influenza, strep pharyngitis, upper respiratory infection, sinusitis, tonsillitis, laryngitis, bronchitis, scarlet fever, and otitis media); sexually transmitted infections (including bacterial vaginosis, chlamydia, genital herpes, HIV/AIDS, human papillomavirus, pelvic inflammatory disease, and trichomoniasis); mononucleosis; shingles; unspecified hepatitis; intestinal infections; and enteritis. These findings highlight that individuals with DS could be more or less prone to different infectious diseases than their non-DS matched counterparts. Additional research to understand why these differences exist and how they might affect the clinical approach to patients with DS is warranted.
RESUMO
Findings from a recent study describing prevalence of common disease conditions in the largest documented cohort of individuals with Down syndrome (DS) in the United States strongly suggested significant disparity in endocrine disorders among these individuals when compared with age- and sex-matched individuals without DS. This retrospective, descriptive study is a follow-up report documenting prevalence of 21 endocrine disorder conditions, across 28 years of data, from 6078 individuals with DS and 30,326 age- and sex-matched controls, abstracted from electronic medical records within a large integrated health system. Overall, individuals with DS experienced higher prevalence of adrenal insufficiency and Addison's disease; thyroid disorders, including hypothyroidism, hyperthyroidism, Hashimoto's disease, and Graves' disease; prolactinoma/hyperprolactinemia; diabetes insipidus; type I diabetes mellitus; and gout. Conversely, those with DS had lower prevalence of polycystic ovary syndrome and type II diabetes mellitus. Many prevalences of endocrine conditions seen in individuals with DS significantly differ relative to their non-DS matched counterparts. These varied findings warrant further exploration into how screening for and treatment of endocrine conditions may need to be approached differently for individuals with DS.
RESUMO
Purpose: This study sought to describe the changes in immune response to a third dose of either Pfizer's or Moderna's COVID-19 mRNA vaccine (3V) among patients with hematologic malignancies, as well as associated characteristics. Methods: This retrospective cohort study analyzed pre-3V and post-3V data on 493 patients diagnosed with hematologic malignancies across a large Midwestern health system between August 28, 2021, and November 1, 2021. For antibody testing, S1 spike antigen of the SARS-CoV-2 virus titer was used to determine serostatus. Results: Among 493 participants, 274 (55.6%) were seropositive both pre- and post-3V (+/+) while 115 (23.3%) seroconverted to positive from prior negative following the third dose (-/+). The remaining 104 (21.1%) were seronegative both before and after 3V (-/-). No participant was seropositive pre-3V and seronegative post-3V (+/-). Results showed a statistically significant increase in the proportion of seropositivity after receiving a third COVID-19 vaccine (P<0.00001). Response to 3V was significantly associated with the 3V vaccine type (P=0.0006), previous COVID-19 infection (P=0.0453), and malignancy diagnosis (P<0.0001). Likelihood of seroconversion (-/+) after 3V was higher in the group of patients with multiple myeloma or related disorders compared to patients with lymphoid leukemias (odds ratio: 8.22, 95% CI: 2.12-31.79; P=0.0008). Conclusions: A third COVID-19 vaccination is effective in producing measurable seroconversion in many patients with hematologic malignancies. Oncologists should actively encourage all their patients, especially those with multiple myeloma, to receive a 3V, given the high likelihood of seroconversion.
RESUMO
OBJECTIVES: Increased exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as a result of having an essential job is compounded by factors such as age, race, and ethnicity. We used a cross-sectional study design to describe disparities in the seroprevalence of SARS-CoV-2 immunoglobulin G (IgG) test results by demographic characteristics and clinical roles among a cohort of health care workers employed by the largest Midwestern health care system in the United States. METHODS: We collected 16 233 SARS-CoV-2 IgG serum samples from June 8 through July 10, 2020, from a convenience sample of Illinois- and Wisconsin-based adult health care workers. The research team, in collaboration with ACL Laboratories, used a SARS-CoV-2 IgG assay to detect the presence of SARS-CoV-2 IgG antibodies. Study data included SARS-CoV-2 IgG assay results and demographic characteristics of workers (age, sex, race, ethnicity, clinical role, zip code). We generated crude and adjusted odds ratios (ORs) to describe disparities in seroprevalence distribution among demographic and social factors. RESULTS: Of 16 233 IgG serum samples tested, 622 (3.8%) test results were positive for SARS-CoV-2. We found significant disparities in SARS-CoV-2 positivity by age, race, ethnicity, and clinical role. Participants aged 32-82 had lower adjusted ORs (aORs) of positive IgG than participants aged 18-31 (aOR range, 0.54-0.66). Odds of positivity were higher among Black (aOR = 3.86), Asian (aOR = 1.42), and mixed-race (aOR = 1.99) workers than among White workers; among Hispanic workers (aOR = 1.80) than among non-Hispanic workers; and among coronavirus disease 2019 (COVID-19) clinical workers (aOR = 1.86) than among nonclinical workers. CONCLUSIONS: Public health efforts should focus on increasing COVID-19 safety messaging, testing, vaccination, and other prevention efforts for people who are young, non-White, Hispanic, and working in COVID-19-clinical units.
