County-Level Social Vulnerability is Associated with Worse Surgical Outcomes Especially Among Minority Patients

The relationship between neighborhood socioeconomic status and short-term outcomes following colon resection

BACKGROUND

This study investigates the association between neighborhood socioeconomic status, measured by the Distressed Communities Index (DCI), and short-term outcomes following colon resection.

METHODS

Utilizing the Maryland State Inpatient Sample database (SID 2018-2020), we determined the association between DCI and post-op outcomes following colon resection including length of stay, readmissions, 30-day in-hospital mortality, and non-routine discharges. Multivariate regression analysis was performed to control for potential confounding factors.

RESULTS

Of the 13,839 patients studied, median age was 63, with 54.3 ​% female and 64.5 ​% elective admissions. Laparoscopic surgery was performed in 36.9 ​% cases, with a median hospital stay of 5 days. Patients in distressed communities faced higher risks of emergency admission (OR: 1.31), prolonged hospitalization (OR: 1.29), non-routine discharges (OR: 1.36), and readmission (OR: 1.33). Black patients had longer stays than White patients (OR: 1.3). Despite adjustments, in-hospital mortality did not significantly differ among neighborhoods.

CONCLUSION

Our study reveals that patients residing in distressed neighborhoods face a higher risk of prolonged hospitalization, non-routine discharges, and readmission rate after colon resection.

Geographic variation in first lower extremity amputations related to diabetes and/or peripheral arterial disease

BACKGROUND

To assess trends of first cases of lower extremity amputations (LEA) related to diabetes and/or peripheral arterial disease (PAD), according to areas of residency and neighbourhood material/social deprivation quintiles, in the province of Quebec, Canada.

METHODS

Using the Quebec Integrated Chronic Disease Surveillance System, we calculated crude and age-standardized annual incidence rates of first LEA (total, minor and major) among adults ≥40 years with diabetes and/or PAD between fiscal years 2006 to 2019. Area of residency was compiled in three categories: 1) Montreal/other census metropolitan areas (CMAs), 2) midsize agglomerations (10,000 to 100,000 inhabitants), and 3) small towns/rural areas (<10,000 inhabitants). We also stratified by neighbourhood material/social deprivation quintiles. One-year and 5-year all-cause mortality after first LEA was compared between areas of residency.

RESULTS

Among the 10,275 individuals who had a first LEA, age-standardized LEA rates remained stable between 2006 and 2019, while major LEA declined in all geographical areas whereas minor LEA increased (31.6%) in small towns/rural areas. In 2019, age-standardized LEA rates were higher in midsize agglomerations and small towns/rural areas compared with CMAs. Age-standardized LEA rates in 2019 were higher among the most deprived quintile compared with the most privileged quintile, for both material/social deprivation. No difference was observed in mortality after first LEA between areas of residency.

CONCLUSION

There are health disparities in the burden of diabetes and PAD related first LEA in the province of Quebec. In order to improve preventive care and reduce the burden of LEA, targeted actions should be taken among the most deprived groups and rural settings.

Poverty and Its Impact on Surgical Care

In this article, the authors explore the intricate relationship between poverty and surgical care, underscoring its multifaceted nature and its profound impact on access and outcomes. Poverty extends beyond financial constraints to encompass barriers related to healthcare infrastructure, geographic isolation, education, mental health, and social determinants of health, resulting in persistent disparities in access to high-quality surgical care, especially for those in persistently impoverished areas and access-sensitive surgical conditions. Additionally, the authors delve into the complex intersection of poverty, race, and ethnicity, emphasizing the heightened risks faced by minority patients in surgical care.

Surgical Urgency, Patient Comorbidities, and Socioeconomic Factors in Surgical Site Infections in Pediatric Surgery

BACKGROUND

The rise of value-based purchasing has led to decreased compensation for hospital-acquired conditions, including surgical site infections (SSI). This study aims to assess the risk factors for SSI in children and teenagers undergoing gastrointestinal surgery across US hospitals.

METHODS

The 2018-2020 Nationwide Readmissions Database was queried for patients undergoing gastrointestinal surgery under the age of 18. The primary outcome was SSI during index admission or readmission within a year. Comparison groups were elective, trauma, and emergent surgery based on anatomic location and urgency. Univariable comparison used chi-squared tests for relevant variables. Confounders were addressed through multivariable logistic regression with significant variables from univariable analysis.

RESULTS

113 108 total patients met the study criteria. The SSI rate during admission or readmission was 2.9% (n = 3254). Infections during admission and readmission were 1.4% (n = 1560) and 1.5% (n = 1694), respectively. The most common site was organ space (48.6%, n = 1657). Increased infection risk was associated with trauma (OR 1.80 [1.51-2.16] P < .001), emergency surgery (OR 1.31 [1.17-1.47] P < .001), large bowel surgery (OR 2.78 [2.26-3.43] P < .001), and those with three or more comorbidities (OR 2.03 [1.69-2.45] P < .001). Investor-owned hospitals (OR .65 [.56-.76] P < .001) and highest quartile income (OR .80 [.73-.88] P < .001) were associated with decreased infection risk.

CONCLUSIONS

Pediatric patients undergoing gastrointestinal surgery face an elevated risk of SSI, especially in trauma and emergency surgeries, particularly with multiple comorbidities. Meanwhile, a reduced risk is observed in high-income and investor-owned hospital settings. Hospitals and surgeons caring for high risk patients should advocate for risk adjustment in value-based payment systems.

The Association of Socio-Environmental Inequality and Outcomes Among Patients Undergoing Major Surgery

INTRODUCTION

Environmental hazards may influence health outcomes and be a driver of health inequalities. We sought to characterize the extent to which social-environmental inequalities were associated with surgical outcomes following a complex operation.

METHODS

In this cross-sectional study, patients who underwent abdominal aortic aneurysm repair, coronary artery bypass grafting, colectomy, pneumonectomy, or pancreatectomy between 2016 and 2021 were identified from Medicare claims data. Patient data were linked with social-environmental data sourced from Centers for Disease Control and Agency for Toxic Substances and Disease Registry data based on county of residence. The Environmental Justice Index social-environmental ranking (SER) was used as a measure of environmental injustice. Multivariable regression analysis was performed to assess the relationship between SER and surgical outcomes.

RESULTS

Among 1,052,040 Medicare beneficiaries, 346,410 (32.9%) individuals lived in counties with low SER, while 357,564 (33.9%) lived in counties with high SER. Patients experiencing greater social-environmental injustice were less likely to achieve textbook outcome (odds ratio 0.95, 95% confidence interval 0.94-0.96, P < 0.001) and to be discharged to an intermediate care facility or home with a health agency (odds ratio 0.97, 95% confidence interval 0.96-0.98, P < 0.001).

CONCLUSIONS

Cumulative social and environmental inequalities, as captured by the Environmental Justice Index SER, were associated with postoperative outcomes among Medicare beneficiaries undergoing a range of surgical procedures. Policy makers should focus on environmental, as well as socioeconomic injustice to address preventable health disparities.

Social Determinants of Health Impact Complications Following Free-Flap Reconstruction for Head and Neck Cancer

OBJECTIVE

Head and neck cancers (HNCs) have increased in prevalence and often require free-flap reconstruction (FFR) after tumor ablation. Postoperative complications following FFR can be high, occurring in as many as 48% and 71% of cases. HNC patients also have many disparities in Social Determinants of Health (SDOH), but the potential impact of SDOH disparities on postoperative complications following FFR has not been formally assessed.

STUDY DESIGN

Retrospective cohort review.

SETTING

Academic Tertiary Care Institution in Northeast United States.

METHODS

Patients that underwent head and neck FFR between January 2018 and December 2021 were analyzed to determine associations between quartiles of the national Area Deprivation Index (ADI), a proxy for SDOH disparity, and various medical and surgical postoperative complications. Associations were assessed using χ2 analysis.

RESULTS

Two hundred four patients were included in the study, and 61 patients had 97 complications. Significant associations between higher national ADI quartile and incidence of several postoperative complications were identified, including any surgical complication (P = .0419), wound dehiscence (P = .0494), myocardial infarction (MI) (P = .0215), and sepsis (P = .0464).

CONCLUSION

There are significant associations between SDOH disparities and postoperative surgical complications, wound dehiscence, MI, and sepsis following head and neck FFR. Addressing SDOH disparities in HNC is pivotal to enhance postoperative outcomes and promote holistic patient care.

The Association of Established Primary Care with Postoperative Outcomes Among Medicare Patients with Digestive Tract Cancer

BACKGROUND

Primary care (PC) is essential to overall wellness and management of comorbidities. In turn, patients without adequate access to PC may face healthcare disparities. We sought to characterize the impact of established PC on postoperative outcomes among patients undergoing a surgical procedure for a digestive tract cancer.

METHODS

Medicare beneficiaries with a diagnosis of hepatobiliary, pancreas, and colorectal cancer between 2005 and 2019 were identified within the Surveillance, Epidemiology, and End Results program and Medicare-linked database. Individuals who did versus did not have PC encounters within 1-year before surgery were identified. A postoperative textbook outcome (TO) was defined as the absence of complications, no prolonged hospital stay, no readmission within 90 days, and no mortality.

RESULTS

Among 63,177 patients, 50,974 (80.7%) had at least one established PC visit before surgery. Patients with established PC were more likely to achieve TO (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.09-1.19) with lower odds for complications (OR, 0.85; 95% CI, 0.72-0.89), extended hospital stay (OR, 0.86; 95% CI, 0.81-0.94), 90-day readmission (OR, 0.94; 95% CI, 0.90-0.99), and 90-day mortality (OR, 0.87; 95% CI, 0.79-0.96). In addition, patients with established PC had a 4.1% decrease in index costs and a 5.2% decrease in 1-year costs. Notably, patients who had one to five visits with their PC in the year before surgery had improved odds of TO (OR, 1.21; 95% CI, 1.16-1.27), whereas individuals with more than 10 visits had lower odds of a postoperative TO (OR, 0.91; 95% CI, 0.84-0.98).

CONCLUSION

Most Medicare beneficiaries with digestive tract cancer had established PC within the year before their surgery. Established PC was associated with a higher probability of achieving ideal outcomes and lower costs. In contrast, patients with more than 10 PC appointments, which was likely a surrogate of overall comorbidity burden, experienced no improvement in postoperative outcomes.

Social vulnerability and perioperative outcomes after colectomy for colon cancer

BACKGROUND

The Social Vulnerability Index (SVI) has previously been demonstrated to correlate with worse postoperative outcomes after surgery, but the association of SVI with short- and long-term outcomes after colon cancer surgery has been underexplored.

METHODS

This is a retrospective cross-sectional study of Medicare patients aged 65 to 99 years who underwent colectomy for colon cancer between 2016 and 2020, merged with SVI at the census tract level. We tested the association between SVI with emergent colectomy and 30-day and 1-year mortality using a multivariable logistic regression model adjusted for patient demographics and hospital characteristics.

RESULTS

The cohort included 169,498 patients who underwent colectomy for colon cancer. Medicare patients living in areas in the highest quintile of social vulnerability were more likely to undergo unplanned colectomy for colon cancer than those in the lowest quintile (35.6% vs 28.9%; adjusted odds ratio [aOR], 1.36; 95% CI, 1.31-1.41; P < .001). Similarly, patients living in areas in the highest quintile of social vulnerability experienced higher risk-adjusted rates of 30-day mortality (3.4% vs 2.9%; aOR, 1.20; 95% CI, 1.12-1.29; P < .001) and 1-year mortality (10.8% vs 8.6%; aOR, 1.30; 95% CI, 1.22-1.37; P < .001) than patients living in the lowest quintile of social vulnerability. When evaluating the elective and unplanned cohorts separately, these differences persisted.

CONCLUSION

Among Medicare patients undergoing colectomy for colon cancer, high social vulnerability was associated with an increased risk of unplanned operations and worse short- and long-term postoperative outcomes in both the emergent and elective settings. Providers should seek to mitigate disparate surgical outcomes by addressing structural inequities in social resources.

Association of US county-level social vulnerability index with breast, colorectal, and lung cancer screening, incidence, and mortality rates across US counties

Background

Despite being the second leading cause of death in the United States, cancer disproportionately affects underserved communities due to multiple social factors like economic instability and limited healthcare access, leading to worse survival outcomes. This cross-sectional database study involves real-world data to explore the relationship between the Social Vulnerability Index (SVI), a measure of community resilience to disasters, and disparities in screening, incidence, and mortality rates of breast, colorectal, and lung cancer. The SVI encompasses four themes: socioeconomic status, household composition & disability, minority status & language, and housing type & transportation.

Materials and methods

Using county-level data, this study compared cancer metrics in U.S. counties and the impact of high and low SVI. Two-sided statistical analysis was performed to compare SVI tertiles and cancer screening, incidence, and mortality rates. The outcomes were analyzed with logistic regression to determine the odds ratio of SVI counties having cancer metrics at or above the median.

Results

Our study encompassed 3,132 United States counties. From publicly available SVI data, we demonstrated that high SVI scores correlate with low breast and colorectal cancer screening rates, along with high incidence and mortality rates for all three types of cancers. County level SVI has impact on incidence rates of cancers; breast cancer rates were lowest in high SVI counties, while colorectal and lung cancer rates were highest in the same counties. Age-adjusted mortality rates for all three cancers increased across SVI tertiles. After risk adjustment, a 10-point SVI increase correlated with lower screening and higher mortality rates.

Conclusion

In conclusion, our study establishes a significant correlation between SVI and cancer metrics, highlighting the potential to identify marginalized communities with health disparities for targeted healthcare initiatives. It underscores the need for further longitudinal studies on bridging the gap in overall cancer care in the United States.

The Role of Delirium on Short- and Long-Term Postoperative Outcomes Following Major Gastrointestinal Surgery for Cancer

INTRODUCTION

The growing burden of an aging population has raised concerns about demands on healthcare systems and resources, particularly in the context of surgical and cancer care. Delirium can affect treatment outcomes and patient recovery. We sought to determine the prevalence of postoperative delirium among patients undergoing digestive tract surgery for malignant indications and to analyze the role of delirium on surgical outcomes.

METHODS

Medicare claims data were queried to identify patients diagnosed with esophageal, gastric, hepatobiliary, pancreatic, and colorectal cancers between 2018 and 2021. Postoperative delirium, occurring within 30 days of operation, was identified via International Classification of Diseases, 10th edition codes. Clinical outcomes of interested included "ideal" textbook outcome (TO), characterized as the absence of complications, an extended hospital stay, readmission within 90 days, or mortality within 90 days. Discharge disposition, intensive care unit (ICU) utilization, and expenditures also were examined.

RESULTS

Among 115,654 cancer patients (esophageal: n = 1854, 1.6%; gastric: n = 4690, 4.1%; hepatobiliary: n = 6873, 5.9%; pancreatic: n = 8912, 7.7%; colorectal: n = 93,325, 90.7%), 2831 (2.4%) were diagnosed with delirium within 30 days after surgery. On multivariable analysis, patients with delirium were less likely to achieve TO (OR 0.27 [95% CI 0.25-0.30]). In particular, patients who experienced delirium had higher odds of complications (OR 3.00 [2.76-3.25]), prolonged length of stay (OR 3.46 [3.18-3.76]), 90-day readmission (OR 1.96 [1.81-2.12]), and 90-day mortality (OR 2.78 [2.51-3.08]). Furthermore, patients with delirium had higher ICU utilization (OR 2.85 [2.62-3.11]). Upon discharge, patients with delirium had a decreased likelihood of being sent home (OR 0.40 [0.36-0.46]) and instead were more likely to be transferred to a skilled nursing facility (OR 2.17 [1.94-2.44]). Due to increased utilization of hospital resources, patients with delirium incurred in-hospital expenditures that were 55.4% higher (no delirium: $16,284 vs. delirium: $28,742) and 90-day expenditures that were 100.7% higher (no delirium: $2564 vs. delirium: $8226) (both p < 0.001). Notably, 3-year postoperative survival was adversely affected by delirium (no delirium: 55.5% vs. delirium: 37.3%), even after adjusting risk for confounding factors (HR 1.79 [1.70-1.90]; p < 0.001).

CONCLUSIONS

Postoperative delirium occurred in one in 50 patients undergoing surgical resection of a digestive tract cancer. Delirium was linked to a reduced likelihood of achieving an optimal postoperative outcome, increased ICU utilization, higher expenditures, and a worse long-term prognosis. Initiatives to prevent delirium are vital to improve postoperative outcomes among cancer surgery patients.

Practice Patterns and Outcomes Among Surgical Oncology Fellowship Graduates Performing Complex Cancer Surgery in the United States Across Different Career Stages

BACKGROUND

Practice patterns and potential quality differences among surgical oncology fellowship graduates relative to years of independent practice have not been defined.

METHODS

Medicare claims were used to identify patients who underwent esophagectomy, pancreatectomy, hepatectomy, or rectal resection for cancer between 2016 and 2021. Surgical oncology fellowship graduates were identified, and the association between years of independent practice, serious complications, and 90-day mortality was examined.

RESULTS

Overall, 11,746 cancer operations (pancreatectomy [61.2%], hepatectomy [19.5%], rectal resection [13.7%], esophagectomy [5.6%]) were performed by 676 surgical oncology fellowship graduates (females: 17.7%). The operations were performed for 4147 patients (35.3%) by early-career surgeons (1-7 years), for 4104 patients (34.9%) by mid-career surgeons (8-14 years), and for 3495 patients (29.8%) by late-career surgeons (>15 years). The patients who had surgery by early-career surgeons were treated more frequently at a Midwestern (24.9% vs. 14.2%) than at a Northeastern institution (20.6% vs. 26.9%) compared with individuals treated by late-career surgeons (p < 0.05). Surgical oncologists had comparable risk-adjusted serious complications and 90-day mortality rates irrespective of career stage (early career [13.0% and 7.2%], mid-career [12.6% and 6.3%], late career [12.8% and 6.5%], respectively; all p > 0.05). Surgeon case-specific volume independently predicted serious complications across all career stages (high vs. low volume: early career [odds ratio {OR}, 0.80; 95% confidence interval {CI}, 0.65-0.98]; mid-career [OR, 0.81; 95% CI, 0.66-0.99]; late career [OR, 0.78; 95% CI, 0.62-0.97]).

CONCLUSION

Among surgical oncology fellowship graduates performing complex cancer surgery, rates of serious complications and 90-day mortality were comparable between the early-career and mid/late-career stages. Individual surgeon case-specific volume was strongly associated with postoperative outcomes irrespective of years of independent practice or career stage.

Long-term Health Outcomes of New Persistent Opioid Use After Gastrointestinal Cancer Surgery

BACKGROUND

New persistent opioid use (NPOU) after surgery has been identified as a common complication. This study sought to assess the long-term health outcomes among patients who experienced NPOU after gastrointestinal (GI) cancer surgery.

METHODS

Patients who underwent surgery for hepato-pancreato-biliary and colorectal cancer between 2007 and 2019 were identified using the Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked database. Mixed-effect multivariable logistic regression and Cox proportional hazard models were used to estimate the risk of mortality and hospital visits related to falls, respiratory events, or pain symptoms.

RESULTS

Among 15,456 patients who underwent GI cancer surgery, 967(6.6%) experienced NPOU. Notably, the patients at risk for the development of NPOU were those with a history of substance abuse (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.14-1.84), moderate social vulnerability (OR, 1.26; 95% CI, 1.06-1.50), an advanced disease stage (OR, 4.42; 95% CI, 3.51-5.82), or perioperative opioid use (OR, 3.07; 95% CI, 2.59-3.63. After control for competing risk factors, patients who experienced NPOU were more likely to visit a hospital for falls, respiratory events, or pain symptoms (OR, 1.45, 95% CI 1.18-1.78). Moreover, patients who experienced NPOU had a greater risk of death at 1 year (hazard ratio [HR], 2.15; 95% CI, 1.74-2.66).

CONCLUSION

Approximately 1 in 15 patients experienced NPOU after GI cancer surgery. NPOU was associated with an increased risk of subsequent hospital visits and higher mortality. Targeted interventions for individuals at higher risk for NPOU after surgery should be used to help mitigate the harmful effects of NPOU.

The Utility of the Social Vulnerability Index as a Proxy for Social Disparities Following Total Knee Arthroplasty

BACKGROUND

In 2021, alternative payment models accounted for 40% of traditional Medicare reimbursements. As such, we sought to examine health disparities through a standardized categorization of social disparity using the social vulnerability index (SVI). We examined (1) risk factors for SVI ≥ 0.50, (2) incidences of complications, and (3) risk factors for total complications between patients who have SVI < 0.50 and SVI ≥ 0.50 who had a total knee arthroplasty (TKA).

METHODS

Patients who underwent TKA between January 1, 2022 and December 31, 2022 were identified in the state of Maryland. A total of 4,952 patients who had complete social determinants of health data were included. Patients were divided into 2 cohorts according to SVI: < 0.50 (n = 2,431) and ≥ 0.50 (n = 2,521) based on the national mean SVI of 0.50. The SVI identifies communities that may need support caused by external stresses on human health based on 4 themed scores: socioeconomic status, household composition and disability, minority status and language, and housing and transportation. The SVI theme of household composition and disability encompassed patients aged 65 years and more, patients aged 17 years and less, civilians who have a disability, single-parent households, and English language deficiencies. The higher the SVI, the more social vulnerability or resources are needed to thrive in a geographic area.

RESULTS

When controlling for risk factors and patient comorbidities, the theme of household composition and disability (odds ratio 2.0, 95% confidence interval 1.1 to 5.0, P = .03) was the only independent risk factor for total complications. Patients who had an SVI ≥0.50 were more likely to be women (65.8% versus 61.0%, P < .001), Black (34.4% versus 12.9%, P < .001), and have a median household income < $87,999 (21.3% versus 10.2%, P < .001) in comparison to the patients who had an SVI < 0.50, respectively.

CONCLUSIONS

The SVI theme of household composition and disability, encompassing patients aged 65 years and more, patients aged 17 years and less, civilians who have a disability, single-parent households, and English language deficiencies, were independent risk factors for total complications following TKA. Together, these findings offer opportunities for interventions with selected patients to address social disparities.

Association of socioeconomic vulnerability with outcomes after emergency general surgery

PURPOSE

Social determinants of health are increasingly recognized to shape health outcomes. Yet, the effect of socioeconomic vulnerability on outcomes after emergency general surgery remains under-studied.

METHODS

All adult (≥18 years) hospitalizations for emergency general surgery operations (appendectomy, cholecystectomy, laparotomy, large bowel resection, perforated ulcer repair, or small bowel resection), within 2 days of non-elective admission were tabulated in the 2016 to 2020 Nationwide Readmissions Database. Socioeconomic vulnerability was defined using relevant diagnosis codes and comprised economic, educational, healthcare, environmental, and social needs. Patients demonstrating socioeconomic vulnerability were considered Vulnerable (others: Non-Vulnerable). Multivariable models were constructed to evaluate the independent associations between socioeconomic vulnerability and key outcomes.

RESULTS

Of ∼1,788,942 patients, 177,764 (9.9%) were considered Vulnerable. Compared to Non-Vulnerable, Vulnerable patients were older (67 [55-77] vs 58 years [41-70), P < .001), more often insured by Medicaid (16.4 vs 12.7%, P < .001), and had a higher Elixhauser Comorbidity Index (4 [3-5] vs 2 [1-3], P < .001). After risk adjustment and with Non-Vulnerable as a reference, Vulnerable remained linked with a greater likelihood of in-hospital mortality (adjusted odds ratio 1.64, confidence interval 1.58-1.70) and any perioperative complication (adjusted odds ratio 2.02, confidence interval 1.98-2.06). Vulnerable also experienced a greater duration of stay (β+4.64 days, confidence interval +4.54-4.74) and hospitalization costs (β+$1,360, confidence interval +980-1,740). Further, the Vulnerable cohort demonstrated increased odds of non-home discharge (adjusted odds ratio 2.44, confidence interval 2.38-2.50) and non-elective readmission within 30 days of discharge (adjusted odds ratio 1.29, confidence interval 1.26-1.32).

CONCLUSION

Socioeconomic vulnerability is independently associated with greater morbidity, resource use, and readmission after emergency general surgery. Novel interventions are needed to build hospital screening and care pathways to improve disparities in outcomes.

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

BACKGROUND

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.

METHODS

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.

RESULTS

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).

CONCLUSIONS

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.

Assessing social disparities in inpatient vs. outpatient arthroplasty: a in-state database analysis

INTRODUCTION

Given the growing emphasis on patient outcomes, including postoperative complications, in total joint arthroplasty (TJA), investigating the rise of outpatient arthroplasty is warranted. Concerns exist over the safety of discharging patients home on the same day due to increased readmission and complication rates. However, psychological benefits and lower costs provide an incentive for outpatient arthroplasty. The influence of social determinants of health disparities on outpatient arthroplasty remains unexplored. One metric that assesses social disparities, including the following individual components: socioeconomic status, household composition, minority status, and housing and transportation, is the Social Vulnerability Index (SVI). As such, we aimed to compare: (1) mean overall SVI and mean SVI for each component and (2) risk factors for total complications between patients undergoing inpatient and outpatient arthroplasty.

METHODS

Patients who underwent TJA between January 1, 2022 and December 31, 2022 were identified. Data were drawn from the Maryland State Inpatient Database (SID). A total of 7817 patients had TJA within this time period. Patients were divided into inpatient arthroplasty (n = 1429) and outpatient arthroplasty (n = 6338). The mean SVI was compared between inpatient and outpatient procedures for each themed score. The SVI identifies communities that may need support cause by external stresses on human health based on four themed scores: socioeconomic status; household composition and disability; minority status and language; and housing and transportation. The SVI uses the United States Census data to rank census tracts for each individual theme, as well as an overall social vulnerability score. The higher the SVI, the more social vulnerability, or resources needed to thrive in that area. Multivariate logistic regression analyses were performed to identify independent risk factors for total complications following TJA after controlling for risk factors and patient comorbidities. Total complications included: infection, aseptic loosening, dislocation, arthrofibrosis, mechanical complication, pain, and periprosthetic fracture.

RESULTS

Patients who had inpatient arthroplasty had higher overall SVI scores (0.45 vs. 0.42, P < 0.001). The SVI scores were higher for patients who had inpatient arthroplasty for socioeconomic status (0.36 vs. 0.32, P < 0.001), minority status and language (0.76 vs. 0.74, P < 0.001), and housing and transportation (0.53 vs. 0.50, P < 0.001) compared to outpatient arthroplasty, respectively. There was no difference between inpatient and outpatient arthroplasty for household composition and disability (0.41 vs. 0.41, P = 0.99). When controlling for comorbidities, inpatient arthroplasty [Odds Ratio (OR) 1.91, 95% Confidence Interval (CI) 1.23-2.95, P = 0.004], hypertension (OR 2.11, 95% CI 1.23-3.62, P = 0.007), and housing and transportation (OR 2.00, 95% CI 1.17-3.42, P = 0.012) were independent risk factors for total complications.

CONCLUSION

Inpatient arthroplasty was associated with increased social disparities across several components of deprivation as well as an independent risk factor total complications following TJA. To the best of our knowledge, this study is the first to examine the negative repercussions of inpatient arthroplasty through the lens of social disparities and can target specific areas for intervention.

Are social determinants of health associated with an increased length of hospitalization after revision total hip and knee arthroplasty? A comparison study of social deprivation indices

INTRODUCTION

Length of stay (LOS) has been extensively assessed as a marker for healthcare utilization, functional outcomes, and cost of care for patients undergoing arthroplasty. The notable patient-to-patient variation in LOS following revision hip and knee total joint arthroplasty (TJA) suggests a potential opportunity to reduce preventable discharge delays. Previous studies investigated the impact of social determinants of health (SDoH) on orthopaedic conditions and outcomes using deprivation indices with inconsistent findings. The aim of the study is to compare the association of three publicly available national indices of social deprivation with prolonged LOS in revision TJA patients.

MATERIALS AND METHODS

1,047 consecutive patients who underwent a revision TJA were included in this retrospective study. Patient demographics, comorbidities, and behavioral characteristics were extracted. Area deprivation index (ADI), social deprivation index (SDI), and social vulnerability index (SVI) were recorded for each patient, following which univariate and multivariate logistic regression analyses were performed to determine the relationship between deprivation measures and prolonged LOS (greater than five days postoperatively).

RESULTS

193 patients had a prolonged LOS following surgery. Categorical ADI was significantly associated with prolonged LOS following surgery (OR = 2.14; 95% CI = 1.30-3.54; p = 0.003). No association with LOS was found using SDI and SVI. When accounting for other covariates, only ASA scores (ORrange=3.43-3.45; p < 0.001) and age (ORrange=1.00-1.03; prange=0.025-0.049) were independently associated with prolonged LOS.

CONCLUSION

The varying relationship observed between the length of stay and socioeconomic markers in this study indicates that the selection of a deprivation index could significantly impact the outcomes when investigating the association between socioeconomic deprivation and clinical outcomes. These results suggest that ADI is a potential metric of social determinants of health that is applicable both clinically and in future policies related to hospital stays including bundled payment plan following revision TJA.

Untangling the Complex Multidimensionality of the Social Determinants of Cardiovascular Health: A Systematic Review

BACKGROUND

The cardiovascular literature is limited by the lack of consensus on what are the best metrics for reporting social determinants of health (SDH) or social deprivation, and if they should be reported as a single metric or separately by their domains.

METHODS

A systematic review of the literature on cardiovascular surgeries and procedures was conducted, identifying articles from January 1, 2010, to December 31, 2023, that studied the relationship between health outcomes after cardiovascular procedures or surgeries and SDH/social deprivation. The cardiovascular procedures/surgeries of interest were coronary and valve surgeries and procedures including coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), valve replacement or repair, and transcatheter aortic valve intervention.

RESULTS

After screening 638 articles, we identified 47 papers that met our inclusion and exclusion criteria. The most common procedure evaluated was CABG and PCI; 46 of the studies focused on these 2 procedures. Almost all of the articles reported a different metric for SDH/social deprivation (41 different metrics); despite this, all of the metrics showed a consistent relationship with worse outcomes associated with greater degrees of SDH/deprivation. Only 9 reported on the individual domains of SDH/social deprivation; 3 studies showed a discordant relationship.

CONCLUSIONS

Although our systematic review identified numerous articles evaluating the relationship between SDH/social deprivation in cardiovascular disease, there was substantial heterogeneity in which metric was used and how it was reported. This reinforces the need for standards as to the best metrics for SDH/social deprivation as well as best practices for reporting.

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

BACKGROUND

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.

METHODS

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.

RESULTS

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).

CONCLUSION

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.

Anatomic Lung Resection Outcomes After Implementation of a Universal Thoracic ERAS Protocol Across a Diverse Health Care System

OBJECTIVE

We sought to evaluate how implementing a thoracic enhanced recovery after surgery (ERAS) protocol impacted surgical outcomes after elective anatomic lung resection.

BACKGROUND

The effect of implementing the ERAS Society/European Society of Thoracic Surgery thoracic ERAS protocol on postoperative outcomes throughout an entire health care system has not yet been reported.

METHODS

This was a prospective cohort study within one health care system (January 2019-March, 2023). A thoracic ERAS protocol was implemented on May 1, 2021 for elective anatomic lung resections, and postoperative outcomes were tracked using the electronic health record and Vizient data. The primary outcome was overall morbidity; secondary outcomes included individual complications, length of stay, opioid use, chest tube duration, and total cost. Patients were grouped into pre-ERAS and post-ERAS cohorts. Bivariable comparisons were performed using independent t -test, χ 2 , or Fisher exact tests, and multivariable logistic regression was performed to control for confounders.

RESULTS

There were 1007 patients in the cohort; 450 (44.7%) were in the post-ERAS group. Mean age was 66.2 years; most patients were female (65.1%), white (83.8%), had a body mass index between 18.5 and 29.9 (69.7%), and were ASA class 3 (80.6%). Patients in the postimplementation group had lower risk-adjusted rates of any morbidity, respiratory complication, pneumonia, surgical site infection, arrhythmias, infections, opioid usage, ICU use, and shorter postoperative length of stay (all P <0.05).

CONCLUSIONS

Postoperative outcomes were improved after the implementation of an evidence-based thoracic ERAS protocol throughout the health care system. This study validates the ERAS Society/European Society of Thoracic Surgery guidelines and demonstrates that simultaneous multihospital implementation can be feasible and effective.

Area Vulnerability and Disparities in Therapy for Patients With Metastatic Renal Cell Carcinoma

Importance

Area-level measures of sociodemographic disadvantage may be associated with racial and ethnic disparities with respect to receipt of treatment for metastatic renal cell carcinoma (mRCC) but have not been investigated previously, to our knowledge.

Objective

To assess the association between area-level measures of social vulnerability and racial and ethnic disparities in the treatment of US Medicare beneficiaries with mRCC from 2015 through 2019.

Design, Setting, and Participants

This retrospective cohort study included Medicare beneficiaries older than 65 years who were diagnosed with mRCC from January 2015 through December 2019 and were enrolled in fee-for-service Medicare Parts A, B, and D from 1 year before through 1 year after presumed diagnosis or until death. Data were analyzed from November 22, 2022, through January 26, 2024.

Exposures

Five different county-level measures of disadvantage and 4 zip code-level measures of vulnerability or deprivation and segregation were used to dichotomize whether an individual resided in the most vulnerable quartile according to each metric. Patient-level factors included age, race and ethnicity, sex, diagnosis year, comorbidities, frailty, Medicare and Medicaid dual enrollment eligibility, and Medicare Part D low-income subsidy (LIS).

Main Outcomes and Measures

The main outcomes were receipt and type of systemic therapy (oral anticancer agent or immunotherapy from 2 months before to 1 year after diagnosis of mRCC) as a function of patient and area-level characteristics. Multivariable regression analyses were used to adjust for patient factors, and odds ratios (ORs) from logistic regression and relative risk ratios (RRRs) from multinomial logistic regression are reported.

Results

The sample included 15 407 patients (mean [SD] age, 75.6 [6.8] years), of whom 9360 (60.8%) were men; 6931 (45.0%), older than 75 years; 93 (0.6%), American Indian or Alaska Native; 257 (1.7%), Asian or Pacific Islander; 757 (4.9%), Hispanic; 1017 (6.6%), non-Hispanic Black; 12 966 (84.2%), non-Hispanic White; 121 (0.8%), other; and 196 (1.3%), unknown. Overall, 8317 patients (54.0%) received some type of systemic therapy. After adjusting for individual factors, no county or zip code-level measures of social vulnerability, deprivation, or segregation were associated with disparities in treatment. In contrast, patient-level factors, including female sex (OR, 0.78; 95% CI, 0.73-0.84) and LIS (OR, 0.48; 95% CI, 0.36-0.65), were associated with lack of treatment, with particularly limited access to immunotherapy for patients with LIS (RRR, 0.25; 95% CI, 0.14-0.43). Associations between individual-level factors and treatment in multivariable analysis were not mediated by the addition of area-level metrics. Disparities by race and ethnicity were consistently and only observed within the most vulnerable areas, as indicated by the top quartile of each vulnerability deprivation index.

Conclusions and Relevance

In this cohort study of older Medicare patients diagnosed with mRCC, individual-level demographics, including race and ethnicity, sex, and income, were associated with receipt of systemic therapy, whereas area-level measures were not. However, individual-level racial and ethnic disparities were largely limited to socially vulnerable areas, suggesting that efforts to improve racial and ethnic disparities may be most effective when targeted to socially vulnerable areas.

The Association of Food Insecurity and Surgical Outcomes Among Patients Undergoing Surgery for Colorectal Cancer

BACKGROUND

Food insecurity predisposes individuals to suboptimal nutrition, leading to chronic disease and poor outcomes.

OBJECTIVE

We sought to assess the impact of county-level food insecurity on colorectal surgical outcomes.

DESIGN

Retrospective cohort study.

SETTING

Data from the Surveillance, Epidemiology, and End Results-Medicare database was merged with county-level food insecurity obtained from the Feeding America: Mapping the Meal Gap report. Multiple logistic and Cox regression adjusted for patient-level covariates were implemented to assess outcomes.

PATIENTS

Medicare beneficiaries diagnosed with colorectal cancer between 2010 and 2015.

MAIN OUTCOME MEASURES

Surgical admission type (nonelective and elective admission), any complication, extended length of stay, discharge disposition (discharged to home and nonhome discharge), 90-day readmission, 90-day mortality, and textbook outcome. Textbook outcome was defined as no extended length of stay, postoperative complications, 90-day readmission, and 90-day mortality.

RESULTS

Among 72,354 patients with colorectal cancer, 46,296 underwent resection. Within the surgical cohort, 9091 (19.3%) were in low, 27,716 (59.9%) were in moderate, and 9,489 (20.5%) were in high food insecurity counties. High food insecurity patients had greater odds of nonelective surgery (OR: 1.17; 95% CI, 1.09-1.26; p < 0.001), 90-day readmission (OR: 1.11; 95% CI, 1.04-1.19; p = 0.002), extended length of stay (OR: 1.32; 95% CI, 1.21-1.44; p < 0.001), and complications (OR: 1.11; 95% CI, 1.03-1.19; p = 0.002). High food insecurity patients also had decreased odds of home discharge (OR: 0.85; 95% CI, 0.79-0.91; p < 0.001) and textbook outcomes (OR: 0.81; 95% CI, 0.75-0.87; p < 0.001). High food insecurity minority patients had increased odds of complications (OR 1.59; 95% CI, 1.43-1.78) and extended length of stay (OR 1.89; 95% CI, 1.69-2.12) compared with low food insecurity white patients (all, p < 0.001). Notably, high food insecurity minority patients had 31% lower odds of textbook outcomes (OR: 0.69; 95% CI, 0.62-0.76; p < 0.001) compared with low food insecurity White patients ( p < 0.001).

LIMITATIONS

This study was limited to Medicare beneficiaries aged 65 years or older; hence, it may not be generalizable to younger populations or those without insurance or with private insurance.

CONCLUSIONS

County-level food insecurity was associated with suboptimal outcomes, demonstrating the importance of interventions to mitigate these inequities. See Video Abstract.

Understanding the Impact of Enhanced Recovery Programs on Social Vulnerability, Race, and Colorectal Surgery Outcomes

BACKGROUND

Increasing social vulnerability, measured by the Social Vulnerability Index, has been associated with worse surgical outcomes. However, less is known about the impact of social vulnerability on patients who underwent colorectal surgery under enhanced recovery programs.

OBJECTIVE

We hypothesized that increasing social vulnerability is associated with worse outcomes before enhanced recovery implementation, but that after implementation, disparities in outcomes would be reduced.

DESIGN

Retrospective cohort study using multivariable logistic regression to identify associations of social vulnerability and enhanced recovery with outcomes.

SETTINGS

Institutional American College of Surgeons National Surgical Quality Improvement Program database.

PATIENTS

Patients undergoing elective colorectal surgery (2010-2020). Enhanced recovery programs were implemented in 2015. Those adhering to 70% or more of enhanced recovery program components were defined as enhanced recovery and all others as nonenhanced recovery.

OUTCOMES

Length of stay, complications, and readmissions.

RESULTS

Of 1523 patients, 589 (38.7%) were in the enhanced recovery group, with 625 patients (41%) in the lowest third of the Social Vulnerability Index, 411 (27%) in the highest third. There were no differences in Social Vulnerability Index distribution by the enhanced recovery group. On multivariable modeling, social vulnerability was not associated with increased length of stay, complications, or readmissions in the enhanced recovery group. Black race was associated with increased length of stay in both the nonenhanced recovery (OR 1.2; 95% CI, 1.1-1.3) and enhanced recovery groups (OR 1.2; 95% CI, 1.1-1.4). Enhanced recovery adherence was associated with reductions in racial disparities in complications as the Black race was associated with increased odds of complications in the nonenhanced recovery group (OR 1.9; 95% CI, 1.2-3.0) but not in the enhanced recovery group (OR 0.8; 95% CI, 0.4-1.6).

LIMITATIONS

Details of potential factors affecting enhanced recovery program adherence were not assessed and are the subject of current work by this team.

CONCLUSION

High social vulnerability was not associated with worse outcomes among both enhanced recovery and nonenhanced recovery colorectal patients. Enhanced recovery program adherence was associated with reductions in racial disparities in complication rates. However, disparities in length of stay remain, and work is needed to understand the underlying mechanisms driving these disparities. See Video Abstract .

COMPRENDIENDO EL IMPACTO DE LOS PROGRAMAS DE RECUPERACIN MEJORADA EN LA VULNERABILIDAD SOCIAL, LA RAZA Y LOS RESULTADOS DE LA CIRUGA COLORRECTAL

ANTECEDENTES:El aumento de la vulnerabilidad social medida por el índice de vulnerabilidad social se ha asociado con peores resultados quirúrgicos. Sin embargo, se sabe menos sobre el impacto de la vulnerabilidad social en los pacientes de cirugía colorrectal bajo programas de recuperación mejorados.OBJETIVO:Planteamos la hipótesis de que el aumento de la vulnerabilidad social se asocia con peores resultados antes de la implementación de la recuperación mejorada, pero después de la implementación, las disparidades en los resultados se reducirían.DISEÑO:Estudio de cohorte retrospectivo que utilizó regresión logística multivariable para identificar asociaciones de vulnerabilidad social y recuperación mejorada con los resultados.ESCENARIO:Base de datos institucional del Programa de Mejora Nacional de la Calidad de la Cirugía del American College of Surgeons.PACIENTES:Pacientes sometidos a cirugía colorrectal electiva (2010-2020).

En el modelo multivariable, la vulnerabilidad social no se asoció con una mayor duración de la estancia hospitalaria, complicaciones o reingresos en ninguno de los grupos de recuperación mejorada. La raza negra se asoció con una mayor duración de la estadía tanto en el grupo de recuperación no mejorada (OR1,2, IC95% 1,1-1,3) como en el grupo de recuperación mejorada (OR1,2, IC95% 1,1-1,4). La adherencia a la recuperación mejorada se asoció con reducciones en las disparidades raciales en las complicaciones, ya que la raza negra se asoció con mayores probabilidades de complicaciones en el grupo de recuperación no mejorada (OR1,9, IC95% 1,2-3,0), pero no en el grupo de recuperación mejorada (OR0,8, IC95% 0,4-1,6).LIMITACIONES:No se evaluaron los detalles de los factores potenciales que afectan la adherencia al programa de recuperación mejorada y son el tema del trabajo actual de este equipo.CONCLUSIÓN:La alta vulnerabilidad social no se asoció con peores resultados entre los pacientes colorrectales con recuperación mejorada y sin recuperación mejorada. Una mayor adherencia al programa de recuperación se asoció con reducciones en las disparidades raciales en las tasas de complicaciones. Sin embargo, persisten disparidades en la duración de la estadía y es necesario trabajar para comprender los mecanismos subyacentes que impulsan estas disparidades.

Racial and Ethnic Minorities With Acute Pancreatitis Live in Neighborhoods With Higher Social Vulnerability Scores

OBJECTIVES

The primary objective was to determine differences in Social Vulnerability Index (SVI) scores among minorities (African-Americans and Hispanics) with acute pancreatitis (AP) compared with non-Hispanic whites (NHWs) with AP. The secondary objectives were to determine differences in diet, sulfidogenic bacteria gene copy numbers (gcn) and hydrogen sulfide (H2S) levels between the 2 groups.

MATERIALS AND METHODS

Patients with AP were enrolled during hospitalization (n = 54). Patient residential addresses were geocoded, and the Centers for Disease Control and Prevention's SVI scores were appended. Dietary intake and serum H2S levels were determined. Microbial DNAs were isolated from stool, and gcn of sulfidogenic bacteria were determined.

RESULTS

Minorities had higher SVI scores compared with NHWs ( P = 0.006). They also had lower consumption of beneficial nutrients such as omega-3 fatty acids [stearidonic ( P = 0.019), and eicosapentaenoic acid ( P = 0.042)], vitamin D ( P = 0.025), and protein from seafood ( P = 0.031). Lastly, minorities had higher pan-dissimilatory sulfite reductase A ( pan-dsrA ) gcn ( P = 0.033) but no significant differences in H2S levels ( P = 0.226).

CONCLUSION

Minorities with AP have higher SVI compared with NHWs with AP. Higher SVI scores, lower consumption of beneficial nutrients, and increased gcn of pan-dsrA in minorities with AP suggest that neighborhood vulnerability could be contributing to AP inequities.

Social vulnerability adversely affects emergency-department utilization but not patient-reported outcomes after total joint arthroplasty

INTRODUCTION

Multiple studies demonstrate social deprivation is associated with inferior outcomes after total hip (THA) and total knee (TKA) arthroplasty; its effect on patient-reported outcomes is debated. The primary objective of this study evaluated the relationship between social vulnerability and the PROMIS-PF measure in patients undergoing THA and TKA. A secondary aim compared social vulnerability between patients who required increased resource utilization or experienced complications and those who didn't.

MATERIALS AND METHODS

A retrospective review of 537 patients from March 2020 to February 2022 was performed. The Centers for Disease Control Social Vulnerability Index (SVI) were used to quantify socioeconomic disadvantage. The cohort was split into THA and TKA populations; univariate and multivariate analyses were performed to evaluate primary and secondary outcomes. Statistical significance was assessed at p < 0.05.

RESULTS

48.6% of patients achieved PROMIS-PF MCID at 1-year postoperatively. Higher levels of overall social vulnerability (0.40 vs. 0.28, p = 0.03) were observed in TKA patients returning to the ED within 90-days of discharge. Increased overall SVI (OR = 9.18, p = 0.027) and household characteristics SVI (OR = 9.57, p = 0.015) were independent risk factors for 90-day ED returns after TKA. In THA patients, increased vulnerability in the household type and transportation dimension was observed in patients requiring 90-day ED returns (0.51 vs. 0.37, p = 0.04).

CONCLUSION

Despite an increased risk for 90-day ED returns, patients with increased social vulnerability still obtain good 1-year functional outcomes. Initiatives seeking to mitigate the effect of social deprivation on TJA outcomes should aim to provide safe alternatives to ED care during early recovery.

Effect of Behavioral Health Disorders on Surgical Outcomes in Cancer Patients

BACKGROUND

Behavioral health disorders (BHDs) can often be exacerbated in the setting of cancer. We sought to define the prevalence of BHD among cancer patients and characterize the association of BHD with surgical outcomes.

STUDY DESIGN

Patients diagnosed with lung, esophageal, gastric, liver, pancreatic, and colorectal cancer between 2018 and 2021 were identified within Medicare Standard Analytic Files. Data on BHD defined as substance abuse, eating disorder, or sleep disorder were obtained. Postoperative textbook outcomes (ie no complications, prolonged length of stay, 90-day readmission, or 90-day mortality), as well as in-hospital expenditures and overall survival were assessed.

RESULTS

Among 694,836 cancer patients, 46,719 (6.7%) patients had at least 1 BHD. Patients with BHD were less likely to undergo resection (no BHD: 23.4% vs BHD: 20.3%; p < 0.001). Among surgical patients, individuals with BHD had higher odds of a complication (odds ratio [OR] 1.32 [1.26 to 1.39]), prolonged length of stay (OR 1.36 [1.29 to 1.43]), and 90-day readmission (OR 1.57 [1.50 to 1.65]) independent of social vulnerability or hospital-volume status resulting in lower odds to achieve a TO (OR 0.66 [0.63 to 0.69]). Surgical patients with BHD also had higher in-hospital expenditures (no BHD: $16,159 vs BHD: $17,432; p < 0.001). Of note, patients with BHD had worse long-term postoperative survival (median, no BHD: 46.6 [45.9 to 46.7] vs BHD: 37.1 [35.6 to 38.7] months) even after controlling for other clinical factors (hazard ratio 1.26 [1.22 to 1.31], p < 0.001).

CONCLUSIONS

BHD was associated with lower likelihood to achieve a postoperative textbook outcome, higher expenditures, as well as worse prognosis. Initiatives to target BHD are needed to improve outcomes of cancer patients undergoing surgery.

Community social vulnerability and the 340B Drug Pricing Program: Evaluating predictors of 340B participation among critical access hospital

PURPOSE

The federal 340B Drug Pricing Program allows eligible hospitals, including critical access hospitals (CAHs), to obtain outpatient drugs at a discounted rate. CAHs likely benefit from 340B participation because they are often under-resourced and serve at-risk patient populations. The objective of this study was to understand predictors of 340B program participation among CAHs, and how participation varies with community-level social vulnerability.

METHODS

We used a cross-sectional study design to assess the relationship between 340B participation in 2019 and community vulnerability status using 2018 data from the CDC's social vulnerability index (SVI) among acute care CAHs. Analyses used linear probability models adjusted for hospital-level characteristics.

FINDINGS

In bivariate analyses, CAHs participating in the 340B program had lower overall social vulnerability scores, relative to nonparticipating, eligible, and ineligible CAHs, respectively (43.8 vs. 48.7 vs. 64.7, p < 0.10). In adjusted regression models, greater community vulnerability rankings due to socioeconomic status (-0.129, p < 0.05) and minority status and language (-0.092, p < 0.05) were associated with decreased 340B participation. Higher hospital operating margin was associated with increased 340B participation (0.163, p < 0.05). Although the number of for-profit CAHs ineligible for 340B was small, they had the highest community-level social vulnerability score and lowest hospital operating margin on average.

CONCLUSIONS

CAHs located in areas of high community vulnerability are less likely to participate in the 340B program. Some vulnerable patient populations served by CAHs may be excluded from 340B program benefits.

Social determinants of health disparities impact postoperative complications in patients undergoing total shoulder arthroplasty

BACKGROUND

Understanding the role of social determinants of health disparities (SDHDs) in surgical outcomes can better prepare providers to improve postoperative care. In this study, we use International Classification of Diseases (ICD) codes to identify SDHDs and investigate the risk of postoperative complication rates among patients undergoing total shoulder arthroplasty (TSA).

METHODS

A retrospective cohort analysis was conducted using a national insurance claims database. Using ICD and Current Procedural Terminology (CPT) codes, patients who underwent primary TSA with at least 2 years of follow-up in the database were identified. Patients with a history of SDHDs were identified using appropriate ICD-9 and ICD-10 codes. Patients were grouped in one of 2 cohorts: (1) patients with no history of SDHDs (control) and (2) patients with a history of SDHDs (SDHD group) prior to TSA. The SDHD and control groups were matched 1:1 for comorbidities and demographics prior to conducting multivariable analysis for 90-day medical complications and 2-year surgical complications.

RESULTS

After matching, there were 8023 patients in the SDHD group and 8023 patients in the control group. The SDHD group had significantly higher odds for 90-day medical complications including heart failure, cerebrovascular accident, renal failure, deep vein thrombosis, pneumonia, sepsis, and urinary tract infection. Additionally, the SDHD group had significantly higher odds for revision surgery within 2 years following TSA. Patients in the SDHD group also had a significantly longer length of hospital stay following TSA.

DISCUSSION

This study highlights the association between SDHDs and postoperative complications following TSA. Quantifying the risk of complications and differences in length of stay for TSA patients with a history of SDHDs is important in determining value-based payment models and risk stratifying to optimize patient care.

Association of social determinants of health International Classification of Disease, Tenth Edition clinical modification codes with outcomes for emergency general surgery and trauma admissions

BACKGROUND

Patients with Acute Care Surgery needs (ie, emergency general surgery diagnosis or trauma admission) are at particularly high risk for nonmedical patient-related factors that can be important drivers of healthcare outcomes. These social determinants of health are typically ascertained at the geographic area level (ie, county or neighborhood) rather than at the individual patient level. Recently, the International Classification of Diseases Tenth Revision, Tenth Edition created codes to capture health hazards related to patient socioeconomic and psychosocial circumstances. We sought to characterize the impact of these social determinants of health-related codes on perioperative outcomes among patients with acute care surgery needs.

METHODS

Patients diagnosed between 2017 and 2020 with acute care surgery needs (ie, emergency general surgery diagnosis or a trauma admission) were identified in the California Department of Healthcare Access and information Patient Discharge database. Data on concomitant social determinants of health-related codes (International Classification of Diseases Tenth Revision, Tenth Edition Z55-Z65), which designated health hazards related to socioeconomic and psychosocial (socioeconomic and psychosocial, respectively) circumstances, were obtained. After controlling for patient factors, including age, sex, race, payer type, and admitting hospital, the association of socioeconomic and psychosocial codes with perioperative outcomes and hospital disposition was analyzed.

RESULTS

Among 483,280 with an acute care surgery admission (emergency general surgery: n = 289,530, 59.9%; trauma: n = 193,705, 40.1%) mean age was 56.5 years (standard deviation: 21.5) and 271,911 (56.3%) individuals were male. Overall, 16,263 (3.4%) patients had a concomitant socioeconomic and psychosocial diagnosis code. The percentage of patients with a concurrent social determinants of health International Classification of Diseases Tenth Revision, Tenth Edition diagnosis increased throughout the study period from 2.6% in 2017 to 4.4% in 2020. Patients that were male (odds ratio 1.89; 95% confidence interval 1.82, 1.96), insured by Medicaid (odds ratio 5.43; 95% confidence interval 5.15, 5.72) or self-pay (odds ratio 3.04; 95% confidence interval 2.75, 3.36) all had higher odds of having an social determinants of health International Classification of Diseases Tenth Revision, Tenth Edition diagnosis. Black race did not have a significant association with an social determinants of health International Classification of Diseases Tenth Revision, Tenth Edition diagnosis (odds ratio 0.99; 95% confidence interval 0.94, 1.04); however, Hispanic (odds ratio 0.44; 95% confidence interval 0.43, 0.46) and Asian (odds ratio 0.40; 95% confidence interval 0.36, 0.44) race/ethnicity was associated with a lower odds of having an social determinants of health International Classification of Diseases Tenth Revision, Tenth Edition diagnosis. After controlling for competing risk factors on multivariable analyses, the risk-adjusted probability of hospital postoperative death was 3.1% (95% confidence interval 2.8, 3.4) among patients with a social determinants of health diagnosis versus 5.9% (95% confidence interval 5.9, 6.0) (odds ratio 0.48; 95% confidence interval 0.44, 0.54) among patients without a social determinants of health diagnosis. Risk-adjusted complications were 26.7% (95% confidence interval 26.1, 37.3) among patients with a social determinants of health diagnosis compared with 31.9% (95% confidence interval 31.7, 32.0) (odds ratio 0.74; 95% confidence interval 0.71, 0.77) among patients without a social determinants of health diagnosis.

CONCLUSION

International Classification of Diseases Tenth Revision, Tenth Edition social determinants of health code use was low, with only 3.4% of patients having documentation of a socioeconomic and psychosocial circumstance. The presence of an International Classification of Diseases Tenth Revision, Tenth Edition social determinants of health code was not associated with greater odds of complications or death; however, it was associated with longer length of stay and higher odds of being discharged to a skilled nursing facility.

The Power of Proximity: Toward an Ethic of Accompaniment in Surgical Care

Although the field of surgical ethics focuses primarily on informed consent, surgical decision-making, and research ethics, some surgeons have started to consider ethical questions regarding justice and solidarity with poor and minoritized populations. To date, those calling for social justice in surgical care have emphasized increased diversity within the ranks of the surgical profession. This article, in contrast, foregrounds the agency of those most affected by injustice by bringing to bear an ethic of accompaniment. The ethic of accompaniment is born from a theological tradition that has motivated work to improve health outcomes in those at the margins through its emphasis on listening, solidarity against systemic drivers of disease, and proximity to individuals and communities. Through a review of surgical ethics and exploration of a central patient case, we argue for applying an ethic of accompaniment to the care of surgical patients and their communities.

Geospatial analysis of cyanobacterial exposure and liver cancer in the contiguous United States

BACKGROUND AND AIMS

Cyanobacteria are commonly found in water bodies and their production of hepatotoxins can contribute to liver damage. However, the population health effects of cyanobacteria exposure (CE) are unknown. Our objectives were to determine the effect of chronic exposure to cyanobacteria through proximity to water bodies with high cyanobacteria counts on the incidence and mortality of liver cancers, as well as to identify location-based risk factors.

APPROACH AND RESULTS

Across the contiguous United States, regions with high cyanobacteria counts in water bodies were identified using satellite remote sensing data. The data were geospatially mapped to county boundaries, and disease mortality and incidence rates were analyzed. Distinctive spatial clusters of CE and mortality related to liver diseases or cancer were identified. There was a highly significant spatial association between CE, liver disease, and liver cancer but not between CE and all cancers. Hot spots of CE and mortality were identified along the Gulf of Mexico, eastern Texas, Louisiana, and Florida, and cold spots across the Appalachians. The social vulnerability index was identified as a major location-based determinant by logistic regression, with counties in the fourth or fifth quintiles having the highest prevalence of hot spots of CE and mortality from liver cancer.

CONCLUSIONS

These findings emphasize the importance of environmental exposure to cyanobacteria as a location-based determinant of mortality from liver cancer. Public health initiatives addressing CE may be considered to reduce mortality, particularly in areas of high social vulnerability.

Disparity in treatment patterns among Medicare beneficiaries diagnosed with chronic lymphocytic leukemia: an analysis of patient and contextual factors

This study characterizes the patterns and timing of CLL treatment and, to our knowledge, is the first to identify social vulnerability factors associated with CLL treatment receipt in the Medicare population. A total of 3508 Medicare beneficiaries diagnosed with CLL from 2017 to 2019 were identified. We reported the proportion of individuals who received CLL treatment and the time until the first CLL treatment receipt after the first observed claim with a CLL diagnosis. Logistic regression and time-to-event models provided adjusted odds ratios and hazard ratios associated with baseline individual-level and county-level factors. Sixteen percent of individuals received CLL treatment, and the median follow-up time was 540 d. The median time to receipt of CLL treatment was 61 d. Older age and residence in a county ranked high in social vulnerability (as defined by minority status and language) were negatively associated with treatment receipt and time to treatment receipt.

Area-Level Socioeconomic Disadvantage and Health Care Spending: A Systematic Review

Importance

Publicly available, US Census-based composite measures of socioeconomic disadvantage are increasingly being used in a wide range of clinical outcomes and health services research. Area Deprivation Index (ADI) and Social Vulnerability Index (SVI) are 2 of the most commonly used measures. There is also early interest in incorporating area-level measures to create more equitable alternative payment models.

Objective

To review the evidence on the association of ADI and SVI with health care spending, including claims-based spending and patient-reported barriers to care due to cost.

Evidence Review

A systematic search for English-language articles and abstracts was performed in the PubMed, Web of Science, Embase, and Cochrane databases (from inception to March 1, 2023). Peer-reviewed articles and abstracts using a cross-sectional, case-control, or cohort study design and based in the US were identified. Data analysis was performed in March 2023.

Findings

This review included 24 articles and abstracts that used a cross-sectional, case-control, or cohort study design. In 20 of 24 studies (83%), ADI and SVI were associated with increased health care spending. No association was observed in the 4 remaining studies, mostly with smaller sample sizes from single centers. In adjusted models, the increase in spending associated with higher ADI or SVI residence was $574 to $1811 for index surgical hospitalizations, $3003 to $24 075 for 30- and 90-day episodes of care, and $3519 for total annual spending for Medicare beneficiaries. In the studies that explored mechanisms, postoperative complications, readmission risk, and poor primary care access emerged as health care system-related drivers of increased spending.

Conclusions and Relevance

The findings of this systematic review suggest that both ADI and SVI can play important roles in efforts to understand drivers of health care spending and in the design of payment and care delivery programs that capture aspects of social risk. At the health care system level, higher health care spending and poor care access associated with ADI or SVI may represent opportunities to codesign interventions with patients from high ADI or SVI areas to improve access to high-value health care and health promotion more broadly.

Association of social vulnerability with receipt of hernia repair in Texas

BACKGROUND

The effect of social health determinants on hernia surgery receipt is unclear. We aimed to assess the association of the social vulnerability index with the likelihood of undergoing elective and emergency hernia repair in Texas.

METHODS

This is a retrospective cohort analysis of the Texas Hospital Inpatient Discharge Public Use Data File and Texas Outpatient Surgical and Radiological Procedure Public Use Data File from 2016 to 2019. Patients ≥18 years old with inguinal or umbilical hernia were included. Social vulnerability index and urban/rural status were merged with the database at the county level. Patients were stratified based on social vulnerability index quartiles, with the lowest quartile (Q1) designated as low vulnerability, Q2 and Q3 as average, and Q4 as high vulnerability. Wilcoxon rank sum, t test, and χ2 analysis were used, as appropriate. The relative risk of undergoing surgery was calculated with subgroup sensitivity analysis.

RESULTS

Of 234,843 patients assessed, 148,139 (63.1%) underwent surgery. Compared to patients with an average social vulnerability index, the low social vulnerability index group was 36% more likely to receive surgery (relative risk: 1.36, 95% CI 1.34-1.37), whereas the high social vulnerability index group was 14% less likely to receive surgery (relative risk: 0.86, 95% CI 0.85-0.86). This remained significant after stratifying for age, sex, insurance status, ethnicity, and urban/rural status (P < .05). For emergency admissions, there was no difference in receipt of surgery by social vulnerability index.

CONCLUSION

Vulnerable patients are less likely to undergo elective surgical hernia repair, even after adjusting for demographics, insurance, and urbanicity. The social vulnerability index may be a useful indicator of social determinants of health barriers to hernia repair.

Social determinants of health in pediatric trauma: Associations with injury mechanisms and outcomes in the context of the COVID-19 pandemic

BACKGROUND

Relationships between social determinants of health and pediatric trauma mechanisms and outcomes are unclear in context of COVID-19.

METHODS

Children <16 years old injured between 2016 and 2021 from ten pediatric trauma centers in Florida were included. Patients were stratified by high vs. low Social Vulnerability Index (SVI). Injury mechanisms studied were child abuse, ATV/golf carts, and firearms. Mechanism incidence trends and mortality were evaluated by interrupted time series and multivariable logistic regression.

RESULTS

Of 19,319 children, 68% and 32% had high and low SVI, respectively. Child abuse increased across SVI strata and did not change with COVID. ATV/golf cart injuries increased after COVID among children with low SVI. Firearm injuries increased after COVID among children with high SVI. Mortality was predicted by injury mechanism, but was not independently associated with SVI, race, or COVID.

CONCLUSION

Social vulnerability influences pediatric trauma mechanisms and COVID effects. Child abuse and firearm injuries should be targeted for prevention.

Social risk and patient-reported outcomes after total knee replacement: Implications for Medicare policy

OBJECTIVE

To determine whether county-level or patient-level social risk factors are associated with patient-reported outcomes after total knee replacement when added to the comprehensive joint replacement risk-adjustment model.

DATA SOURCES AND STUDY SETTING

Patient and outcomes data from the Function and Outcomes Research for Comparative Effectiveness in Total Joint Replacement cohort were merged with the Social Vulnerability Index from the Centers for Disease Control and Prevention.

STUDY DESIGN

This prospective longitudinal cohort measured the change in patient-reported pain and physical function from baseline to 12 months after surgery. The cohort included a nationally diverse sample of adult patients who received elective unilateral knee replacement between 2012 and 2015.

DATA COLLECTION/EXTRACTION METHODS

Using a national network of over 230 surgeons in 28 states, the cohort study enrolled patients from diverse settings and collected one-year outcomes after the surgery. Patients <65 years of age or who did not report outcomes were excluded.

PRINCIPAL FINDINGS

After adjusting for clinical and demographic factors, we found patient-reported race, education, and income were associated with patient-reported pain or functional scores. Pain improvement was negatively associated with Black race (CI = -8.71, -3.02) and positively associated with higher annual incomes (≥$45,00) (CI = 0.07, 2.33). Functional improvement was also negatively associated with Black race (CI = -5.81, -0.35). Patients with higher educational attainment (CI = -2.35, -0.06) reported significantly less functional improvement while patients in households with three adults reported greater improvement (CI = 0.11, 4.57). We did not observe any associations between county-level social vulnerability and change in pain or function.

CONCLUSIONS

We found patient-level social factors were associated with patient-reported outcomes after total knee replacement, but county-level social vulnerability was not. Our findings suggest patient-level social factors warrant further investigation to promote health equity in patient-reported outcomes after total knee replacement.

National patterns in the use of International Statistical Classification of Diseases and Health Related Problems, tenth revision Z codes in ambulatory surgery from 2016 to 2019

BACKGROUND

In the tenth revision of the International Statistical Classification of Disease and Health Related Problems (ICD-10), Z codes were added to improve documentation and understanding of health-related social needs. We estimated national Z code use in the ambulatory surgery setting from 2016 to 2019.

METHODS

Using the Nationwide Ambulatory Surgery Sample (NASS), we identified encounters for ambulatory surgery with an ICD-10 code between Z55.0 and Z65.9. Data were stratified by Z code domains from the Centers for Medicare and Medicaid Services (CMS).

RESULTS

This analysis of 41,827 ambulatory surgery encounters with documented Z codes found that the most documented determinants of health related to multiparity or unwanted pregnancy, homelessness, and incarceration. There was a 16.1% increase in the use of Z codes from 2016 to 2019.

CONCLUSION

Rates of Z code use in the ambulatory surgery setting are increasing with current documentation serving as a specific but not sensitive measure of socioeconomic need.

Evaluating the Relationship between Neighborhood-Level Social Vulnerability and Patient Adherence to Ophthalmology Appointments

PURPOSE

To examine the association between neighborhood-level social vulnerability and adherence to scheduled ophthalmology appointments.

METHODS

In this retrospective cohort study, records of all patients ≥18 years scheduled for an ophthalmology appointment between September 12, 2020, and February 8, 2021, were reviewed. Primary exposure is neighborhood-level Social Vulnerability Index (SVI) based on the patient's residential location. SVI is a rank score of 15 social factors into four themes (socioeconomic status, household composition/disability, minority status/language, and housing type/transportation), ranging from 0 to 1.0, with higher ranks indicating greater social vulnerability. The overall SVI score and each theme were analyzed separately as the primary exposure of interest in multivariable logistic regression models that controlled for age, sex, appointment status (new or established), race, and distance from clinic. The primary outcome, non-adherence, was defined as missing more than 25% of scheduled appointments.

RESULTS

Of 8,322 patients (41% non-Hispanic Black, 24% Hispanic, 22% non-Hispanic White) with scheduled appointments, 28% were non-adherent. Non-adherence was associated with greater social vulnerability (adjusted odds ratio [aOR] per 0.01 increase in overall SVI = 2.46 [95% confidence interval, 1.99, 3.06]) and each SVI theme (socioeconomic status: aOR = 2.38 [1.94, 2.91]; household composition/disability: aOR = = 1.51 [1.26, 1.81]; minority status/language: aOR = 2.03 [1.55, 2.68]; housing type/transportation: aOR = 1.41 [1.16, 1.73]).

CONCLUSION

Neighborhood-level social vulnerability is associated with greater risk of non-adherence to scheduled ophthalmology appointments, controlling for individual characteristics. Multi-level intervention strategies that incorporate neighborhood-level vulnerabilities are needed to reduce disparities in access to ophthalmology care.

Surgeon Understanding and Perceptions of Social Determinants of Health

INTRODUCTION

Social determinants of health impact surgical outcomes. Characterization of surgeon understanding of social determinants of health is necessary prior to implementation of interventions to address patient needs. The study objective was to explore understanding, perceived importance, and practices regarding social determinants of health among surgeons.

METHODS

Surgical residents and attending surgeons at a single academic medical center completed surveys regarding social determinants of health. We conducted semi-structured interviews to further explore understanding and perceived importance. A conceptual framework from the World Health Organization (WHO) Commission on Social Determinants of Health informed the thematic analysis.

RESULTS

Survey response rate was 47.9% (n = 69, 44 residents [63.8%], 25 attendings [36.2%]). Respondents primarily reported good (n = 29, 42.0%) understanding of social determinants of health and perceived this understanding to be very important (n = 42, 60.9%). Documentation occurred seldom (n = 35, 50.7%), and referrals occurred seldom (n = 26, 37.7%) or never (n = 20, 29.0%). Residents reported a higher rate of prior training than attendings (95.5% versus 56.0%, P < 0.001). Ten interviews were conducted (six residents, four attendings). Residents demonstrated greater understanding of socioeconomic positions and hierarchies shaped by structural mechanisms than attendings. Both residents and attendings demonstrated understanding of intermediary determinants of health status and linked social determinants to impacting patients' health and well-being. Specific knowledge gaps were identified regarding underlying structural mechanisms including the social, economic, and political context that influence an individual's socioeconomic position.

CONCLUSIONS

Self-reported understanding and importance of social determinants of health among surgeons were high. Interviews revealed gaps in understanding that may contribute to limited practices.

Association of ICD-10 Clinical Modification Codes for Social Determinants of Health with Surgical Outcomes and Hospital Charges Among Cancer Patients

INTRODUCTION

We sought to characterize the impact of social determinants of health (SDOH)-related codes on outcomes among patients with a cancer diagnosis.

METHODS

Patients diagnosed with lung, pancreas, colon, or rectal cancer between 2017 and 2020 were identified in the California Department of Healthcare Access and Information Patient Discharge Database. Data on concomitant SDOH-related codes (International Classification of Diseases, Tenth Revision [ICD-10] Z55-Z65) designating health hazards related to socioeconomic and psychosocial circumstances were obtained. The association of these SDOH codes with postoperative outcomes was evaluated.

RESULTS

Among 10,421 patients who underwent an operation from 2017 to 2020, median age was 66 years (interquartile range [IQR] 56-75) and nearly half of the cohort was male (n = 551,252.9%). In total, 102 (1%) patients had a concurrent ICD-10 SDOH diagnosis. After controlling for competing risk factors, the risk-adjusted probability of in-hospital death was 4.1% (95% confidence interval [CI] 1.0-7.2) among patients with an SDOH diagnosis compared with 2.9% (95% CI 2.5-3.2) among patients without an SDOH diagnosis (odds ratio [OR] 1.52, 95% CI 0.63-3.66; p = 0.258); postoperative complications were 27.0% (95% CI 20.0-34.1) compared with 24.9% (95% CI 24.1-25.6) among patients without an SDOH diagnosis (OR 1.15, 95% CI 0.73-1.82; p = 0.141), and length of stay was 10.6 days (95% CI 10.0-11.2) compared with 9.4 days (95% CI 9.3-9.5) among patients without an SDOH diagnosis. Patients with an SDOH diagnosis had a 5.19 (95% CI 3.23-8.34; p < 0.005) higher odds of being discharged to a skilled nursing facility versus patients without an SDOH diagnosis.

CONCLUSION

Uptake and utilization of ICD-10 SDOH was 1% among California patients with lung, pancreas, colon, or rectal cancer. Patients with a concomitant ICD-10 SDOH code had longer length of stay and had higher odds of being discharged to a skilled nursing facility.

Surgeon Supply by County-Level Rurality and Social Vulnerability From 2010 to 2020

This cross-sectional study examines the surgical workforce in all counties across the US from 2010 to 2020.

Associations Between Social Vulnerability Indicators and Pediatric Tonsillectomy Outcomes

OBJECTIVE

To investigate the impact of neighborhood-level social vulnerability on pediatric tonsillectomy outcomes.

METHODS

This single-center retrospective cohort study included tonsillectomies performed on children aged 1 to 18 between August 2019 and August 2020. Geographic information systems were used to geocode addresses, and spatial overlays were used to assign census-tract level social vulnerability index (SVI) scores to each patient. For categorical variables, two-sided Pearson chi-square tests were used, whereas for continuous variables, paired t-tests, means, and standard deviations were calculated. SVI and its four subthemes were investigated using binomial logistic regressions to determine their impact on post-T&A complications and readmissions.

RESULTS

The study included 397 patients, with 52 having complications (13.1%) and 33 (8.3%) requiring readmissions due to their complications. Controlling for age, gender, race, insurance status, surgical indication, comorbidities, obesity, and obstructive sleep apnea, postoperative complications were associated with high overall SVI (odds ratio [OR] 5.086, 95% confidence interval [CI] 1.128-22.938), high socioeconomic vulnerability (SVI theme 1, OR 6.003, 95% CI 1.270-28.385), and high house composition vulnerability (SVI theme 2, OR 6.340, 95% CI 1.275-31.525). Readmissions were also associated with high overall SVI (10.149, 95% CI 1.293-79.647) and high housing/transportation vulnerability (SVI theme 4, OR 5.657, 95% CI 1.089-29.396).

CONCLUSION

Social vulnerability at the neighborhood level is linked to poorer surgical outcomes in otherwise healthy children, suggesting a target for community-based interventions. Because of the increased risk, it may have implications for preoperative decision-making, treatment plans, and clinic follow-ups.

Social vulnerability and time to surgeon evaluation for primary hyperparathyroidism in a Massachusetts cohort

BACKGROUND

Identifying patients at risk for under-evaluation of primary hyperparathyroidism is essential to minimizing long-term sequelae, including osteoporosis, nephrolithiasis, and cardiovascular disease. This study assessed the impact of social vulnerability on time-to-surgery evaluation among patients with primary hyperparathyroidism in a Massachusetts cohort.

METHODS

This is a retrospective review of patients from an institutional database with the first incident of hypercalcemia between 2010 and 2018 and subsequent biochemical diagnosis of primary hyperparathyroidism. The overall social vulnerability index and social vulnerability index subthemes were merged with the institutional data via patient ZIP code. Patients were stratified into social vulnerability index quartiles, where quartile 4 represented the highest vulnerability. Baseline sociodemographic and clinical characteristics were compared, and Cox regression was used to assess the association between social vulnerability index and time to surgeon evaluation.

RESULTS

Of 1,082 patients included, those with a higher social vulnerability index were less likely to be evaluated by a surgeon (quartile 1 social vulnerability index: 31.1% vs. quartile 2 social vulnerability index: 31.41% vs. quartile 3 social vulnerability index: 25.93% vs. quartile 4 social vulnerability index: 21.92%, P = .03). On adjusted analysis, patients with the highest vulnerability had a 33% lower estimated rate of surgeon evaluation and were seen 67 days later compared with patients with the lowest vulnerability (hazard ratio: 0.67, confidence interval 0.47-0.97, P = .032). Differential rates of surgical evaluation by vulnerability persisted for the social vulnerability index subthemes for socioeconomic status, minority status and language, and housing type and transportation.

CONCLUSION

Among a Massachusetts cohort, highly vulnerable populations with primary hyperparathyroidism are at greater risk for under-evaluation by a surgeon, which may contribute to the development of long-term sequelae of their disease.

Association Between Social Vulnerability Index and Hospital Readmission Following Gunshot Injuries

INTRODUCTION

No association regarding classification of social vulnerability and outcomes of patients with gunshot injury have been described. Our goal was to assess whether the socioeconomic vulnerability index (SVI), is associated with an increased risk of hospital readmission following gunshot wounds.

METHODS

We conducted an exploratory retrospective cohort study on Massachusetts patients with trauma following gunshot wounds from January 1, 2012 to December 31, 2020 using the institutional trauma registry. We estimated the association between high social vulnerability (defined by the Centers for Disease Control and Prevention as ≥90th percentile) and incidence of all-cause readmission at 30, 60, and 90 d (overall and stratified over sex, race, and age groups). Estimates from unadjusted log-binomial regression were reported using relative risks (RRs) and 95% confidence intervals. Time-to-event (readmission) was assessed using Kaplan-Meier plots.

RESULTS

A total of 386 patients were included for analysis: 211 (55%) with SVI <0.90 and 175 (45%) with SVI ≥0.90. The mean (standard deviation) age was 29 (13) y, with majority being male (89%). There was no strong risk of readmission associated with SVI ≥0.90; the interval with the greatest risk was at 60 d (RR = 1.34; 95% confidence interval [0.73, 2.45]). Among stratified analyses, the strongest associations were observed when restricting to young adults (aged 18-35) with RRs of 2.49, 2.62, and 2.45 for 30, 60, and 90 d readmission, respectively.

CONCLUSIONS

Overall, high SVI was not associated with all-cause readmission; however, subanalyses suggest an association among young adults. Future research should explore SVI as a tool for identifying patients with trauma at risk for readmission.

Social vulnerability and new mobility disability among adults with polymerase chain reaction (PCR)-confirmed SARS-CoV-2: Michigan COVID-19 Recovery Surveillance Study

OBJECTIVE

Understanding the relationship between social factors and persistent COVID-19 health outcomes, such as onset of a disability after a SARS-CoV-2 (the virus that causes COVID-19) infection, is an increasingly important public health issue. The purpose of this paper is to examine associations between social vulnerability and new onset of a mobility disability post-COVID-19 diagnosis.

METHODS

We used data from the Michigan COVID-19 Recovery Surveillance Study, a population-based probability survey of adults with PCR-confirmed SARS-CoV-2 infection in Michigan between January 2020-May 2022 (n = 4295). We used the Minority Health Social Vulnerability Index (MHSVI), with high county-level social vulnerability defined at or above the 75th percentile. Mobility disability was defined as new difficulty walking or climbing stairs. We regressed mobility disability on the overall MHSVI, as well as sub-themes of the index (socioeconomic status, household composition/disability, minority and language, housing type, healthcare access, and medical vulnerability), using multivariable logistic regression, adjusting for age, race, sex, education, employment, and income.

RESULTS

Living in a county with high (vs. low) social vulnerability was associated with 1.38 times higher odds (95% confidence interval [CI]:1.18-1.61) of reporting a new mobility disability after a COVID-19 diagnosis after adjustment. Similar results were observed for the socioeconomic status and household composition/disability sub-themes. In contrast, residents of highly racially diverse counties had lower odds (odds ratio 0.74, 95% CI: 0.61, 0.89) of reporting a new mobility disability compared to low diversity counties.

CONCLUSIONS

Mitigating the effects of social vulnerabilities requires additional resources and attention to support affected individuals.

Risk factors associated with post-acute sequelae of SARS-CoV-2: an N3C and NIH RECOVER study

BACKGROUND

More than one-third of individuals experience post-acute sequelae of SARS-CoV-2 infection (PASC, which includes long-COVID). The objective is to identify risk factors associated with PASC/long-COVID diagnosis.

METHODS

This was a retrospective case-control study including 31 health systems in the United States from the National COVID Cohort Collaborative (N3C). 8,325 individuals with PASC (defined by the presence of the International Classification of Diseases, version 10 code U09.9 or a long-COVID clinic visit) matched to 41,625 controls within the same health system and COVID index date within ± 45 days of the corresponding case's earliest COVID index date. Measurements of risk factors included demographics, comorbidities, treatment and acute characteristics related to COVID-19. Multivariable logistic regression, random forest, and XGBoost were used to determine the associations between risk factors and PASC.

RESULTS

Among 8,325 individuals with PASC, the majority were > 50 years of age (56.6%), female (62.8%), and non-Hispanic White (68.6%). In logistic regression, middle-age categories (40 to 69 years; OR ranging from 2.32 to 2.58), female sex (OR 1.4, 95% CI 1.33-1.48), hospitalization associated with COVID-19 (OR 3.8, 95% CI 3.05-4.73), long (8-30 days, OR 1.69, 95% CI 1.31-2.17) or extended hospital stay (30 + days, OR 3.38, 95% CI 2.45-4.67), receipt of mechanical ventilation (OR 1.44, 95% CI 1.18-1.74), and several comorbidities including depression (OR 1.50, 95% CI 1.40-1.60), chronic lung disease (OR 1.63, 95% CI 1.53-1.74), and obesity (OR 1.23, 95% CI 1.16-1.3) were associated with increased likelihood of PASC diagnosis or care at a long-COVID clinic. Characteristics associated with a lower likelihood of PASC diagnosis or care at a long-COVID clinic included younger age (18 to 29 years), male sex, non-Hispanic Black race, and comorbidities such as substance abuse, cardiomyopathy, psychosis, and dementia. More doctors per capita in the county of residence was associated with an increased likelihood of PASC diagnosis or care at a long-COVID clinic. Our findings were consistent in sensitivity analyses using a variety of analytic techniques and approaches to select controls.

CONCLUSIONS

This national study identified important risk factors for PASC diagnosis such as middle age, severe COVID-19 disease, and specific comorbidities. Further clinical and epidemiological research is needed to better understand underlying mechanisms and the potential role of vaccines and therapeutics in altering PASC course.

Barriers and Facilitators to Ophthalmology Visit Adherence in an Urban Hospital Setting

Purpose

To explore barriers and facilitators to completing scheduled outpatient appointments at an urban academic hospital-based ophthalmology department.

Methods

Potential participants were stratified by neighborhood Social Vulnerability Index (SVI) (range, 0-1.0, higher scores indicate greater vulnerability), and semistructured interviews were conducted with individuals 18 years and older with an SVI of greater than 0.61 (n = 17) and providers delivering care in the General Eye Clinic of the University of Illinois Chicago (n = 8). Qualitative analysis informed by human-centered design methods was conducted to classify barriers and facilitators into three domains of the Consolidated Framework for Implementation Research: outer setting, inner setting, and characteristics of individuals.

Results

There were four main themes-transportation, time burden, social support, and economic situation-all of which were within the outer setting of the Consolidated Framework for Implementation Research; transportation was most salient. Although providers perceived health literacy as a barrier affecting motivation, patients expressed a high motivation to attend visits and felt well-educated about their condition.

Conclusions

A lack of resources outside of the health system presents significant barriers for patients from neighborhoods with high SVI. Future efforts to improve adherence should focus on resource-related interventions in the outer setting. Improving access to eye care will require community-level interventions, particularly transportation.

Translational Relevance

Understanding the barriers and facilitators within the Consolidated Framework for Implementation Research provides useful guidance for future interventions, specifically to focus future efforts to improve adherence on resource-related interventions.

Social vulnerability is associated with increased postoperative morbidity following esophagectomy

OBJECTIVES

The effect of a patient's Social Vulnerability Index (SVI) on complication rates after esophagectomy remains unstudied. The purpose of this study was to determine how social vulnerability influences morbidity following esophagectomy.

METHODS

This was a retrospective review of a prospectively collected esophagectomy database at one academic institution, 2016 to 2022. Patients were grouped into low-SVI (<75%ile) and high-SVI (>75%ile) cohorts. The primary outcome was overall postoperative complication rate; secondary outcomes were rates of individual complications. Perioperative patient variables and postoperative complication rates were compared between the 2 groups. Multivariable logistic regression was used to control for covariates.

RESULTS

Of 149 patients identified who underwent esophagectomy, 27 (18.1%) were in the high-SVI group. Patients with high SVI were more likely to be of Hispanic ethnicity (18.5% vs 4.9%, P = .029), but there were no other differences in perioperative characteristics between groups. Patients with high SVI were significantly more likely to develop a postoperative complication (66.7% vs 36.9%, P = .005) and had greater rates of postoperative pneumonia (25.9% vs 6.6%, P = .007), jejunal feeding-tube complications (14.8% vs 3.3%, P = .036), and unplanned intensive care unit readmission (29.6% vs 12.3%, P = .037). In addition, patients with high SVI had a longer postoperative hospital length of stay (13 vs 10 days, P = .017). There were no differences in mortality rates. These findings persisted on multivariable analysis.

CONCLUSIONS

Patients with high SVI have greater rates of postoperative morbidity following esophagectomy. The effect of SVI on esophagectomy outcomes warrants further investigation and may prove useful in identifying populations that benefit from interventions to mitigate these complications.
