Census tract-level social vulnerability and gonorrhea rates in central Ohio: results from the STD Surveillance Network, 2020-2021.

Gonorrhea remains a significant burden in central Ohio, particularly in socially disadvantaged communities. This study evaluates gonorrhea case rates and changes from 2020 to 2021, focusing on geographic patterns associated with social vulnerability. We analyzed gonorrhea case data from the Columbus STD Surveillance Network (SSuN) for 2020 and 2021. Cases were linked to census tracts and categorized into low (0-0.66) or high (0.67-1.0) vulnerability groups based on the CDC/ATSDR social vulnerability index (SVI). We mapped gonorrhea case rates per 100,000 population, stratified by SVI group, and compared changes using Jenks natural breaks to determine cutpoints. High case rates were defined as ≥605 (2020) and ≥ 532 (2021). A change in case rates was defined as <154 (decrease/no change) or ≥ 154 (increase). Demographic factors were summarized for both years. In 2020 and 2021, nearly half of high SVI tracts had high gonorrhea rates, compared to about 4-7% of low SVI tracts. Median rates in high SVI tracts were approximately five times higher than in low SVI tracts, with rates 546 and 598 per 100,000 in 2020 and 2021, compared to 98 and 104 per 100,000, respectively. Gonorrhea rates increased in 23 (9%) of low SVI tracts and 37 (25%) of high SVI tracts. Demographic characteristics remained consistent between the two years. Gonorrhea rates increased in central Ohio between 2020 and 2021, with higher burdens in high SVI census tracts. Understanding the dynamics of social vulnerability at the community level is crucial for targeting limited STD resources effectively.

Waitlist Time, Age, and Social Vulnerability: Impact on the Survival Benefit of Deceased Donor Kidney Transplantation Versus Long-term Dialysis Among Patients With End-stage Renal Disease.

We sought to define the survival benefit of kidney transplantation versus long-term dialysis relative to waitlist time on dialysis, social vulnerability, and age among end-stage renal transplant candidates. End-stage renal disease patients who were candidates for their first deceased donor kidney transplantation between 2008 and 2020 were identified using the US Renal Data System. Survival probabilities for patient survival were compared using the restricted mean survival times (RMSTs) across different age and social vulnerability index (SVI) ranges. Among 149 923 patients, 68 795 (45.9%) patients underwent a kidney transplant and 81 128 (54.1%) remained on dialysis. After propensity-score matching (n = 58 035 in each cohort), the 5-y RMST difference between kidney transplant and dialysis demonstrated an increasing trend in mean life-years gained within 5 y of follow-up relative to advancing age (<30 y: 0.40 y, 95% confidence interval, 0.36-0.44 y versus >70 y: 0.75 y, 95% confidence interval, 0.70-0.80 y). Conversely, disparities in 5-y RMSTs remained consistent relative to social vulnerability (median 5-y RMST difference: 0.62 y comparing low versus high SVI). When considering waitlist duration, stratified analyses demonstrated increasing trends across different age groups with the largest RMST differences observed among older patients aged ≥70 y. Notably, longer waitlist durations (>3 y) yielded more pronounced RMST differences compared with shorter durations (<1 y). These data underscore the survival benefit associated with kidney transplantation over long-term dialysis across various age and SVI ranges. Transplantation demonstrated a greater advantage among older patients who had a longer waitlist duration.

Association of social vulnerability and rehospitalization in pediatric motor vehicle trauma patients

IntroductionWe investigated social vulnerability index (SVI) as a tool to identify children at risk for readmission following motor vehicle collisions (MVC). Materials and MethodsAn exploratory retrospective cohort study was conducted of pediatric trauma activations (age 0–15) for MVCs 1/1/2012 to 6/30/2022 at a level 1 trauma center. Eligibility included residence within our center's catchment area. Excluded were mortalities during the index admission. Patient address was geocoded and linked with state-level census tract SVI. Per the CDC, SVI ≥90th percentile defined high vulnerability. We evaluated SVI theme: socioeconomic status (SES), household composition and disability (HCD), minority status and language (MSL), housing and transportation (HT). Outcomes included emergency department (ED) visits and re-hospitalization within 90 days of discharge. Kaplan-Meier plots, relative risk (aRR), and 95 % confidence intervals (95 %CI) adjusted for injury severity score (ISS) were estimated using log-binomial regression. ResultsOf 429 eligible subjects, 122 (28 %) resided in high SVI communities. High SVI patients had slightly higher mean ISS (8.6 vs 7.5). There was a similar risk of ED re-presentation across SVI groups (aRR=1.18; 95 %CI 0.61–2.29). However, although estimates were unstable, there was a possibility of increased risk of re-hospitalization among the high SVI group (aRR=2.34; 95 %CI 0.68–8.04). By theme, HT had the strongest association (aRR=1.71) for ED representation, whereas SES and HCD had the strongest associations for rehospitalization (aRR=2.03, 2.66, respectively). ConclusionWe observed possible associations between high SVI and higher rates of re-hospitalization. Future research with a larger sample may clarify associations.

Vulnerable populations and the emergency ventral hernia: A retrospective cohort study

IntroductionVentral hernias can be repaired electively; however, many circumstances require emergency repair. The association between sociodemographic status and rate of emergency repair are unclear and the Social Vulnerability Index may be a useful tool to better understanding this association. The purpose of this study was to investigate the association between Social Vulnerability Index and emergency ventral hernia repair. MethodsThis was a retrospective cohort study using the National Surgical Quality Improvement Program (2012–2018) data for patients at a level 1 trauma center. We included patients who had an open ventral hernia repair. Social Vulnerability Index was based on residential address at the time of surgery. We conducted univariate and bivariate statistics, including χ2 and Mann-Whitney U tests to compare high and low social vulnerability. ResultsOur sample had 1,017 patients. Patients who underwent emergency operations were older (P = .025) and had higher Social Vulnerability Index (P = .029). Patients in the high Social Vulnerability Index group were 1.5 times more likely to receive emergency surgery (P = .047). Emergency repair was also associated with increased frequency of nonhome discharge (9% vs 2%, P = .001) and higher mean work relative value unit (15.4 vs 11.9, P < .001). ConclusionPatients requiring emergency ventral hernia repair have significantly higher Social Vulnerability Index than those undergoing elective repair. This vulnerable population also has increased cost associated with the repair and higher rates of nonhome discharge. This work provides a foundation for efforts to reach patients in high Social Vulnerability Index environments at an earlier stage to achieve earlier elective repair.

Social disparities in delivery choice among patients with history of cesarean

ObjectiveGiven the call to reduce rates of non-medically indicated cesarean deliveries (CDs) by encouraging trials of labor after cesarean (TOLAC), this study looks at social characteristics of patients choosing a TOLAC versus a scheduled repeat cesarean delivery (SRCD) to determine disparities regarding delivery method choice. MethodsThis was a retrospective cohort study of patients with a history of one CD between April 29, 2015–April 29, 2020. Patients were divided based on type of delivery chosen at admission. Chi-squared tests examined proportional differences between groups and logistic regression models examined odd ratios of choosing TOLAC versus SRCD according to socially dependent categories including race/ethnicity, health insurance, pre-pregnancy body mass index, and Social Vulnerability Index (SVI). Results1,983 patients were included. Multivariable logistic regression models revealed that patients with a high SVI (reference: low/medium SVI) (AOR 2.0, CI: 1.5, 2.5), self-identified as Black/ African American (AOR: 2.4, CI: 1.6, 3.6) or Hispanic/Latina (AOR: 2.0, CI: 1.4, 2.8) (reference: White), had public insurance (reference: private insurance) (AOR: 3.7, CI: 2.8, 5.0), and who had an obese BMI (reference: non-obese BMI) were more likely to opt for a TOLAC rather than SRCD. ConclusionThese findings demonstrate differences in delivery method preferences. Specifically, more disadvantaged patients are more likely to choose TOLAC, suggesting that social and economic factors may play a role in delivery preferences. These findings have implications for improving individualized counselling and engaging in shared decision-making around mode of delivery.

Impact of social vulnerability index on severity of obstructive sleep apnea: Insights from drug-induced sleep endoscopy

ObjectivesTo examine the association between neighborhood-level social vulnerability on the severity of obstructive sleep apnea (OSA) in patients undergoing drug-induced sleep endoscopy (DISE). Study designSingle center retrospective cohort study. MethodsWe conducted a retrospective chart review of patients >18 years of age that underwent DISE from July 2016 to July 2022. Patient addresses were geocoded with geographic information systems, and spatial overlays were used to assign census-tract level social vulnerability index (SVI) scores in the four sub-themes: Socioeconomic (theme 1), Household Composition/Disability (theme 2), Minority Status/Language (theme 3), and Housing/Transportation (theme 4). ResultsThe study included 165 patients (61.2 years ± 11.6; 31.0 BMI ± 6.1, 102 male, 63 female). Mild OSA was present in13 patients; 55 patients had moderate OSA; and 97 patients had severe OSA. A higher SVI value in minority status and language, and a higher BMI both predicted an increased Apnea Hypopnea Index (AHI) (p = 0.042, and <0.001, respectively) in the multivariate model; whereas, race, age, gender, or the other three SVI sub-theme values were not predictive. ConclusionAdults residing in areas of greater social vulnerability – specifically a larger minority presence or English as a second language – and patients who are obese are more likely to have more severe OSA. There was no correlation, however, between obesity and residence in an area of high SVI. These results suggest that both neighborhood conditions and obesity are associated with OSA severity. This elevated risk has potential implications for diagnostic testing, clinic follow-ups, screening, and treatment plans for adults residing in disenfranchised neighborhoods. Level of evidenceIV.

Impact of a proactive patient assistance program for diverse ambulatory oncology patients: A retrospective cohort study.

e13513 Background: Significant differences persist in cancer incidence, survival, morbidity, and mortality among populations in the U.S. Individuals of lower socioeconomic status (SES) suffer disproportionately from cancer and other disease burdens compared to individuals with higher SES. Financial hardship is increasingly common, with many cancer survivors reporting difficulty paying medical bills, high financial distress, and delaying or forgoing care because of cost. Cancer patients reporting financial hardship are more likely to have psychosocial distress. Financial distress has been linked with several clinically relevant patient outcomes including quality of life, symptom burden, compliance, and survival. An NCI-designated comprehensive cancer center (CCC) with a diverse racial, ethnic, and linguistic patient population utilizes My Wellness Check (MWC) program to identify patients experiencing emotional, physical, practical, and social concerns. Among 4,117 MWC patient responders representing 43.1% of eligible patients during October 2019 - February 2022, 801 patients (19.5%) with 976 supportive or practical needs alerts were triggered to social workers where only 68.4% of the alerts were acted upon within a 72-hour window. For patients identified by MWC as having financial toxicity, Social Workers identified available resources to assist with patients’ out-of-pocket costs. Methods: In July 2022, the CCC launched a patient financial assistance program which included screening of all patients receiving systemic therapy administered at infusion centers. A third-party partner was contracted to provide patient advocates and technology augmenting the EHR. Patient Advocates identified eligible patients and enrolled them into financial assistance programs. Results: A retrospective analysis was performed for the period of May 2022 - December 2023, comparing patients receiving philanthropic medical financial assistance consisting of copay assistance and grants sponsored by drug manufacturers and diagnosis based non-profit foundations with infusion center patient population demographic data. The cohort participating in patient assistance programs included a higher percentage of female, Hispanic, age 27-64, commercially insured, and patients that reside in high and medium-high Social Vulnerability Index (SVI) counties. Conclusions: A proactive patient financial assistance program can help reduce financial distress for patients with cancer, especially those residing in high and medium high SVI counties. Leveraging the expertise of a third party helps mitigate financial toxicity in the short term and can help drive more equitable cancer outcomes.

Buprenorphine Prescribing and Challenges Faced Among National Health Service Corps Clinicians

The National Health Service Corps (NHSC) Loan Repayment Program (LRP) expansion in fiscal year (FY) 2019 intended to improve access to medication for opioid use disorder (MOUD) by adding more clinicians who could prescribe buprenorphine. However, some clinicians still face barriers to prescribing, which may vary between rural and nonrural areas. To examine the growth in buprenorphine prescribing by NHSC clinicians for Medicaid beneficiaries during the NHSC LRP expansion and describe the challenges to prescribing that persist in rural and nonrural areas. This cross-sectional study analyzed preexpansion and postexpansion Medicaid claims data to evaluate the percentage of prescriptions of buprenorphine filled during FY 2017 through 2021. This study also analyzed challenges and barriers to prescribing MOUD between rural and urban areas, using results from annual surveys conducted with NHSC clinicians and sites from FY 2019 through FY 2021. Prescribing of buprenorphine by NHSC clinicians. The main outcomes were the percentage and number of Medicaid beneficiaries with opioid use disorder (OUD) who filled a prescription for buprenorphine before and after the LRP expansion and the challenges NHSC clinicians and sites faced in providing substance use disorder and OUD services. Survey results were analyzed using descriptive statistics. During FYs 2017 through 2021, 7828 NHSC clinicians prescribed buprenorphine (standard LRP: mean [SD] age, 38.1 [8.4] years and 4807 females [78.9%]; expansion LRPs: mean [SD] age, 39.4 [8.1] years and 1307 females [75.0%]). A total of 3297 NHSC clinicians and 4732 NHSC sites responded to at least 1 survey question to the 3 surveys. The overall percentage of Medicaid beneficiaries with OUD who filled a prescription for buprenorphine during the first 2.5 years post expansion increased significantly from 18.9% before to 43.7% after expansion (an increase of 123 422 beneficiaries; P < .001). The percentage more than doubled among beneficiaries living in areas with a high Social Vulnerability Index score (from 17.0% to 36.7%; an increase of 31 964) and among beneficiaries living in rural areas (from 20.8% to 55.7%; an increase of 45 523). However, 773 of 2140 clinicians (36.1%; 95% CI, 33.6%-38.6%) reported a lack of mental health services to complement medication for OUD treatment, and 290 of 1032 clinicians (28.1%; 95% CI, 24.7%-31.7%) reported that they did not prescribe buprenorphine due to a lack of supervision, mentorship, or peer consultation. These findings suggest that although the X-waiver requirement has been removed and Substance Abuse and Mental Health Services Administration guidelines encourage all eligible clinicians to screen and offer patients with OUD buprenorphine, as permissible by state law, more trained health care workers and improved care coordination for counseling and referral services are needed to support comprehensive OUD treatment.

Association of county-level provider density and social vulnerability with colorectal cancer-related mortality

BackgroundHealth care providers play a crucial role in increasing overall awareness, screening, and treatment of cancer, leading to reduced cancer mortality. We sought to characterize the impact of provider density on colorectal cancer population-level mortality. MethodsCounty-level provider data, obtained from the Area Health Resource File between 2016 and 2018, were used to calculate provider density per county. These data were merged with county-level colorectal cancer mortality 2016–2020 data from the Centers for Disease Control and Prevention. Multivariable regression was performed to define the association between provider density and colorectal cancer mortality. ResultsAmong 2,863 counties included in the analytic cohort, 1,132 (39.5%) and 1,731 (60.5%) counties were categorized as urban and rural, respectively. The colorectal cancer-related crude mortality rate was higher in counties with low provider density versus counties with moderate or high provider density (low = 22.9, moderate = 21.6, high = 19.3 per 100,000 individuals; P < .001). On multivariable analysis, the odds of colorectal cancer mortality were lower in counties with moderate and high provider density versus counties with low provider density (moderate odds ratio 0.97, 95% confidence interval 0.94–0.99; high odds ratio 0.88, 95% confidence interval 0.86–0.91). High provider density remained associated with a lower likelihood of colorectal cancer mortality independent of social vulnerability index (low social vulnerability index and high provider density: odds ratio 0.85, 95% confidence interval 0.81–0.89; high social vulnerability index and high provider density: odds ratio 0.93, 95% confidence interval 0.89–0.98). ConclusionRegardless of social vulnerability index, high county-level provider density was associated with lower colorectal cancer-related mortality. Efforts to increase access to health care providers may improve health care equity, as well as long-term cancer outcomes.

Examining thermal inequities: Land surface temperature, social vulnerability, and historical redlining in San Antonio, TX

Rising urban temperatures significantly impact human health, with their effects varying across socio-economic groups. With a focus on San Antonio, Texas, during its notably intense summer heat in 2023, this research explores the intricate relationship between urban heat and social vulnerability. Through the analysis of Land Surface Temperature (LST) data from Landsat 8 data, captured during three exceptionally hot days, a positive correlation between LST and the Social Vulnerability Index (SVI) was revealed. This relationship shows that areas with higher SVI, indicative of greater vulnerability, consistently experience higher LSTs. The study further investigated two distinct census tracts: one in a previously redlined area with a high SVI and another in a ‘A-best’ HOLC area with a low SVI. The comparative study between these two tracts revealed significant Normalized Difference Vegetation Index (NDVI) and subsequent thermal variances. It was found that the tract in the historically redlined area consistently experiences higher minimum and mean LST, indicating how past housing policies continue to impact present-day environmental and social conditions. Findings reveal the critical connection between urban heat and social vulnerability, contributing to a broader understanding of the interplay between historical and social factors in shaping thermal inequities in a historically redlined city.

Association of School Instructional Mode with Community COVID-19 Incidence during August-December 2020 in Cuyahoga County, Ohio.

Remote and hybrid modes of instruction were employed as alternatives to in-person instruction as part of early mitigation efforts in response to the COVID-19 pandemic. We investigated the impact of a public school district's instructional mode on cumulative incidence and transmission in the surrounding community by employing a generalized estimating equations approach to estimate the association with weekly COVID-19 case counts by zip code in Cuyahoga County, Ohio, from August to December 2020. Remote instruction only (RI) was employed by 7 of 20 school districts; 13 used some non-remote instruction (NRI) (2-15 weeks). Weekly incidence increased in all zip codes from August to peak in late fall before declining. The zip code cumulative incidence within NRI school districts was higher than in those offering only RI (risk ratio = 1.12, p = 0.01; risk difference = 519 per 100,000, 95% confidence interval (123-519)). The mean effect for NRI on emergent cases 2 weeks after mode exposure, controlling for Social Vulnerability Index (SVI), was significant only for high SVI zip codes 1.30, p < 0.001. NRI may be associated with increased community COVID-19 incidence, particularly in communities with high SVI. Vulnerable communities may need more resources to open schools safely.

The Association Between Social Vulnerability and Oncologic Stage and Treatment in the United States

ObjectiveGrowing evidence supports the impact of sociodemographics on cancer outcomes. The objective of this study was to examine the Social Vulnerability Index (SVI) and its association with oncologic presentation and subsequent treatments across 8 major cancers. MethodsThis was a retrospective-cohort study using one institution’s contribution to the National Cancer Database (2011–2021). Patients were grouped into low SVI (<75th percentile) and high SVI (≥75th percentile) cohorts. Un-adjusted comparison between groups was performed followed by multivariable regression to control for the effect of demographic characteristics on oncologic presentation, and for demographic and oncologic characteristics on subsequent treatments. A subgroup analysis was performed comparing cancers that have national screening protocols versus those without. ResultsOf 12,712 cases, 2,842 (22.4%) were in the high SVI group and 9,870 (77.6%). After risk-adjustment, high SVI patients presented at more advanced T-stage (odds ratio 1.09, 95% confidence interval 1.00-1.19); N-stage (1.11, 1.01–1.23); M stage (1.16, 1.03–1.30); and overall stage (1.14, 1.04–1.24) and were more frequently not recommended for surgery (1.15, 1.01–1.32) or chemotherapy (1.20, 1.07–1.38). Screening protocols tended to increase the association between high SVI and advanced oncologic presentation. After adjustment high SVI remained significantly associated with decreased odds of survival (0.85, 0.79 - 0.91). ConclusionsHigh SVI is associated with advanced stage presentation and decreased likelihood of being recommended surgery or chemotherapy even after risk-adjustment. Differences in presentation stage are predominantly driven by cancers with screening protocols and ultimately high SVI is associated with decreased odds of survival.

Abstract 34: Social Risks, Glycemic Control and Elevated Blood Pressure Among Patients With Diabetes in the Ascension Health System

Background: Calls to address social risks have stimulated interest in integrating screening measures into the electronic medical record (EMR) - particularly, self-reported individual level social risks - to improve care for chronic diseases like diabetes (DM). Objective: Examine associations between individual-level social risks and glycemic control and elevated blood pressure (BP) among patients with DM in the Ascension Health System. Methods: A 10-item EMR-embedded survey [access to care, resources, transportation, employment] was collected in Ascension primary care clinics in 12 U.S. states. Neighborhood-level risk was characterized with the CDC Social Vulnerability index (SVI) by census tract of patients’ residences. Associations between social risk (individual/composite) and uncontrolled DM (HbA1c &gt;9%) and elevated BP (&gt;120/80) adjusting for age, sex, race/ethnicity, SVI, region, and chronic conditions were examined. Results: Among 75,848 patients with DM and social risk data available [median age 62, 53% female, 22% Black, 7.5% Hispanic]. 20% had poor glycemic control; 27% had elevated BP; 20% lived in a high SVI census tract. Patients identifying any social risk were more likely to have poor glycemic or elevated BP. Patients with the highest social risk scores had higher odds of uncontrolled glycemia (OR 1.72, 95% CI 1.60-1.85) and elevated BP (OR 1.18, 95% CI 1.10-1.26). Conclusion: Examination of a large sample of primary care patients in a large multi-region health system determined that individual-level social risks were correlated with glycemic and BP control. These data highlight the need to simultaneously address social risks and medical conditions to impact population health.

Social Vulnerability Index and Survivorship after Colorectal Cancer Resection.

Race and socioeconomic status incompletely identify patients with colorectal cancer (CRC) at the highest risk for screening, treatment, and mortality disparities. Social vulnerability index (SVI) was designed to delineate neighborhoods requiring greater support after external health stressors, summarizing socioeconomic, household, and transportation barriers by census tract. SVI is implicated in lower cancer center use and increased complications after colectomy, but its influence on long-term prognosis is unknown. Herein, we characterized relationships between SVI and CRC survival. Patients undergoing resection of stage I to IV CRC from January 2010 to May 2023 within an academic health system were identified. Clinicopathologic characteristics were abstracted using institutional National Cancer Database and NSQIP. Addresses from electronic health records were geocoded to SVI. Overall survival and cancer-specific survival were compared using Kaplan-Meier and Cox proportional hazards methods. A total of 872 patients were identified, comprising 573 (66%) patients with colon tumor and 299 (34%) with rectal tumor. Patients in the top SVI quartile (32%) were more likely to be Black (41% vs 13%, p < 0.001), carry less private insurance (39% vs 48%, p = 0.02), and experience greater comorbidity (American Society of Anesthesiologists physical status III: 86% vs 71%, p < 0.001), without significant differences by acuity, stage, or CRC therapy. In multivariable analysis, high SVI remained associated with higher all-cause (hazard ratio 1.48, 95% CI 1.12 to 1.96, p < 0.01) and cancer-specific survival mortality (hazard ratio 1.71, 95% CI 1.10 to 2.67, p = 0.02). High SVI was independently associated with poorer prognosis after CRC resection beyond the perioperative period. Acknowledging needs for multi-institutional evaluation and elaborating causal mechanisms, neighborhood-level vulnerability may inform targeted outreach in CRC care.

Analysis of missed clinic visits, preferred languages, and telemedicine in a pediatric gastroenterology practice.

Previous studies have demonstrated a relationship between socioeconomic disparities and missed clinic visits (MCV). However, the relationship between patient-preferred language and MCVs, particularly with respect to telemedicine, remains relatively underexplored. We sought to characterize the associations between MCV and patient-level predictors, including preferred language, in a large single-center pediatric gastroenterology, hepatology, and nutrition practice. This retrospective longitudinal cohort study included all missed or completed outpatient visits in the Gastroenterology, Hepatology, and Nutrition Programs at Boston Children's Hospital from January 1, 2016to May 20, 2022. Univariate and multivariate hierarchical generalized linear mixed models were employed to identify associations between visit- and patient-level predictors and an MCV outcome. A total of 300,201 visits from 70,710 patients residing in Massachusetts were included. Univariate analyses revealed higher MCV odds for Hispanic patients and those from areas with the highest Social Vulnerability Index (SVI), and these odds increased with telemedicine (Hispanic in-person odds ratio [OR] 5.21 [(95% confidence interval) 4.93-5.52] vs. telemedicine OR 8.79 [7.85-9.83]; highest SVI in-person OR 5.28 [4.95-5.64] vs. telemedicine OR 7.82 [6.84-8.96]). Controlled multivariate analyses revealed that among six language groups, only Spanish language preference was associated with higher MCV odds, which increased with telemedicine (Spanish in-person adjusted OR [aOR]1.35 [1.24-1.48] vs. telemedicine aOR 2.1 [1.83-2.44]). Patients preferring Spanish experience unique barriers to care beyond those faced by other language preference groups, and telemedicine may exacerbate these barriers.

Trends in survival after heart transplantation based on Social Vulnerability Index in the United States

IntroductionThe association of social vulnerability (SV) and cardiac transplant survival remains poorly defined, particularly related to long-term outcomes. The purpose of this study was to define the impact of SV on survival among heart transplant recipients with at least 1-year of survival post-transplant. MethodsHeart transplant recipients were identified using the United Network for Organ Sharing database between 6/1/06-12/31/20. The Center for Disease Control’s Social Vulnerability Index (SVI) database was used to stratify patients based on SVI into three groups: Low: <25; Average: 26-74; High: 75+. The groups were analyzed with comparative statistics, and unadjusted survival was assessed using Kaplan-Meier methods. To determine the independent association between SVI and survival, a multivariable Cox proportional hazard model was created. ResultsThere were 27,740 recipients identified. High SVI patients more commonly identified as Black individuals and had a higher incidence of diabetes, pre-transplant intensive care unit admission and need for concomitant kidney transplant (p<0.05 for all). Additionally, High SVI patients had the longest length of stay post-transplant (21.4 days) (p<0.05). High and Average SVI patients had inferior 3-year, 5-year, and 10-year survival versus Low SVI patients (p<0.05). After adjustment, Average (hazard ratio [HR]:1.12) and High (HR:1.16) SVI were independently associated with an increased risk of mortality on multivariable analysis (both p<0.001). ConclusionHigh or average SVI is independently associated with increased mortality following heart transplantation in patients with 1-year conditional survival. These findings demonstrate that disparities persist among heart transplant recipients during long-term follow up.

Abstract A022: Detecting cardiovascular disease risk in early-stage endometrial cancer survivors: preliminary evidence of pulse wave velocity and social vulnerability index

Abstract BACKGROUND: Endometrial cancer survivors (ECS) experience high rates of cardiovascular disease (CVD) likely due to lifestyle and social-environmental factors, including high obesity rates up to 60%. Early detection of CVD is crucial in order to intervene; however, strategies to identify ECS most at risk for CVD are currently lacking. The gold-standard methodology to non-invasively measure CVD is pulse wave velocity (PWV), and one way to identify social-environmental susceptibility is the Centers for Disease Control social vulnerability index (SVI). PURPOSE: Therefore, the purpose of this study is to investigate (1) CVD risk in stage 1 ECS using PWV and (2) the social-environmental influence on CVD risk using SVI. METHODS: Stage 1 ECS who were 1-12 months post-treatment, with a BMI ≥ 25.0 kg/m2, age 50-80 years, and English speaking were recruited in the gynecology-oncology clinic. Oscillometric PWV was measured in a supine position via Mobil-O-Graph. Body composition [body fat percentage (%)] was measured via Bioelectrical Impedance Analysis. Participant zip code was used to determine SVI of their county of residence. SVI is defined as low-medium (0.00-0.49), medium-high (0.50-0.69), and high (0.70-1.00). Linear regression was used to compare PWV and SVI. RESULTS: Seventeen ECS (65% White, 25% Black, 5% Asian, 5% American Indian, 64 ± 7 years old, 6 ± 4 months post-treatment, 44 ± 6% body fat) participated in the study. Participants resided in counties with low-medium (18%), medium-high (24%), and high (58%) SVI and PWV was measured as 8.2 ± 0.8 m/s, 9.1 ± 0.8 m/s, and 9.7 ± 1.0 m/s respectively. The overall regression was not statistically significant (R=0.38, R2=0.14, F=1.15, p=0.34). DISCUSSION: Overall, PWV was elevated in ECS residing in counties with medium-high and high SVI categories compared to normative data. PWV can be used to non-invasively measure CVD risk in clinic in early-stage ECS. Despite failing to reach statistical significance, a 1.0 m/s change is considered to be a clinically meaningful difference in PWV. Therefore, ECS residing in counties with high SVI may be at greater CVD risk compared to those living in less vulnerable communities. Further research is needed, including a larger sample size, to identify successful interventions to reduce CVD in ECS most at risk. Citation Format: Lauren C.

High Community-Level Social Vulnerability is Associated with Worse Recurrence-Free Survival (RFS) After Resection of Extremity and Truncal Soft Tissue Sarcoma.

Although social vulnerability has been associated with worse postoperative and oncologic outcomes in other cancer types, these effects have not been characterized in patients with soft tissue sarcoma. This study evaluated the association of social vulnerability and oncologic outcomes. The authors conducted a single-institution cohort study of adult patients with primary and locally recurrent extremity or truncal soft tissue sarcoma undergoing resection between January 2016 and December 2021. The social vulnerability index (SVI) was measured on a low (SVI 1-39%, least vulnerable) to high (60-100%, most vulnerable) SVI scale. The association of SVI with overall survival (OS) and recurrence-free survival (RFS) was evaluated by Kaplan-Meier analysis and Cox proportional hazard regression. The study identified 577 patients. The median SVI was 44 (interquartile range [IQR], 19-67), with 195 patients categorized as high SVI and 265 patients as low SVI. The median age, tumor size, histologic subtype, grade, comorbidities, stage, follow-up time, and perioperative chemotherapy and radiation utilization were similar between the high and low SVI cohorts. The patients with high SVI had worse OS (p = 0.07) and RFS (p = 0.016) than the patients with low SVI. High SVI was independently associated with shorter RFS in the multivariate analysis (hazard ratio, 1.64; 95% confidence interval, 1.06-2.54) but not with OS (HR, 1.47; 95% CI 0.84-2.56). High community-level social vulnerability appears to be independently associated with worse RFS for patients undergoing resection of extremity and truncal soft tissue sarcoma. The effect of patient and community-level social risk factors should be considered in the treatment of patients with extremity sarcoma.

Association Between Social Vulnerability and SARS-CoV-2 Seroprevalence in Specimens Collected From Commercial Laboratories, United States, September 2021-February 2022.

We conducted a national US study of SARS-CoV-2 seroprevalence by Social Vulnerability Index (SVI) that included pediatric data and compared the Delta and Omicron periods during the COVID-19 pandemic. The objective of the current study was to assess the association between SVI and seroprevalence of infection-induced SARS-CoV-2 antibodies by period (Delta vs Omicron) and age group. We used results of infection-induced SARS-CoV-2 antibody assays of clinical sera specimens (N = 406 469) from 50 US states from September 2021 through February 2022 to estimate seroprevalence overall and by county SVI tercile. Bivariate analyses and multilevel logistic regression models assessed the association of seropositivity with SVI and its themes by age group (0-17, ≥18 y) and period (Delta: September-November 2021; Omicron: December 2021-February 2022). Aggregate infection-induced SARS-CoV-2 antibody seroprevalence increased at all 3 SVI levels; it ranged from 25.8% to 33.5% in September 2021 and from 53.1% to 63.5% in February 2022. Of the 4 SVI themes, socioeconomic status had the strongest association with seroprevalence. During the Delta period, we found significantly more infections per reported case among people living in a county with high SVI (odds ratio [OR] = 2.76; 95% CI, 2.31-3.21) than in a county with low SVI (OR = 1.65; 95% CI, 1.33-1.97); we found no significant difference during the Omicron period. Otherwise, findings were consistent across subanalyses by age group and period. Among both children and adults, and during both the Delta and Omicron periods, counties with high SVI had significantly higher SARS-CoV-2 antibody seroprevalence than counties with low SVI did. These disparities reinforce SVI's value in identifying communities that need tailored prevention efforts during public health emergencies and resources to recover from their effects.

Association of COVID-19 Pandemic with Colorectal Cancer Screening: Impact of Race/Ethnicity and Social Vulnerability

BackgroundThe COVID-19 pandemic disrupted health care delivery, including cancer screening practices. This study sought to determine the impact of the COVID-19 pandemic lockdown on colorectal cancer (CRC) screening relative to social vulnerability.MethodsUsing the Medicare Standard Analytic File, individuals 65 years old or older who were eligible for guideline-concordant CRC screening between 2019 and 2021 were identified. These data were merged with the Center for Disease Control Social Vulnerability Index (SVI) dataset. Changes in county-level monthly screening volumes relative to the start of the COVID-19 pandemic (March 2020) and easing of restrictions (March 2021) were assessed relative to SVI.ResultsAmong 10,503,180 individuals continuously enrolled in Medicare with no prior diagnosis of CRC, 1,362,457 (12.97%) underwent CRC screening between 2019 and 2021. With the COVID-19 pandemic, CRC screening decreased markedly across the United States (median monthly screening: pre-pandemic [n = 76,444] vs pandemic era [n = 60,826]; median Δn = 15,618; p < 0.001). The 1-year post-pandemic overall CRC screening utilization generally rebounded to pre-COVID-19 levels (monthly median screening volumes: pandemic era [n = 60,826] vs post-pandemic [n = 74,170]; median Δn = 13,344; p < 0.001). Individuals residing in counties with the highest SVI experienced a larger decline in CRC screening odds than individuals residing in low-SVI counties (reference, low SVI: pre-pandemic high SVI [OR, 0.85] vs pandemic high SVI [OR, 0.81] vs post-pandemic high SVI [OR, 0.85]; all p < 0.001).ConclusionsThe COVID-19 pandemic was associated with a decrease in CRC screening volumes. Patients who resided in high social vulnerability areas experienced the greatest pandemic-related decline.
