Disparities in Emergency Versus Elective Surgery: Comparing Measures of Neighborhood Social Vulnerability

The Complexity of Social Vulnerability of Person and Place on Mortality After Penetrating Trauma

INTRODUCTION

Social determinants of health impact outcomes after traumatic injury. Patient factors, including race, insurance status, and household income, have been associated with increased risk of mortality and worse outcomes. The social vulnerability index (SVI) is a comprehensive tool that quantifies these factors at the census tract or county level. We hypothesized that mortality after admission for penetrating trauma would be associated with higher vulnerability.

MATERIALS AND METHODS

We queried our level 1 trauma center supplemental database from 2019 to 2021 for mortality among adult patients presenting with a penetrating traumatic injury (n = 103). We assigned SVI based on patient address and location of injury. We used chi-square tests for association for all categorical variables and Mann-Whitney U tests for continuous variables. We then conducted a logistic regression and mediation analysis to assess the effect of injury severity score on mortality.

RESULTS

We found a significant association between SVI and mortality after comparing low and high SVI. While most patients with penetrating trauma came from the areas of highest SVI (64%), patients with low SVI (2nd and 3rd quartiles) had a higher mortality than those of the highest quartile (33.3% versus 14.1%, P = 0.021). High vulnerability was associated with improved survival and lower rates of all-cause mortality; however, this association was entirely mediated by the greater range of injury severity seen in the high-vulnerability group. The correlation between individual SVI and SVI of place of injury was strong.

CONCLUSIONS

SVI is associated with patient mortality after penetrating trauma in our locale, but not in the ways that we assumed. Our data suggest that we are missing the areas where disparity in care exists when considering only patients who make it to a trauma center. This may reflect the vulnerability of the immediate area around our institution such that a greater range of survivable injury presents and emphasizes the utility of secondary and tertiary violence prevention in the communities immediately surrounding our hospital.

Social Vulnerability Index in Emergency General Surgery Outcomes: A Systematic Review

BackgroundThe Social Vulnerability Index (SVI) has also been used as a measure of social determinants of health (SDOH), with several studies showing worse health outcomes in patients with higher burdens of SDOH. This systematic review focuses on the application of SVI in Emergency General Surgery (EGS), exploring the impact of patient vulnerability on individual health outcomes.MethodsA systematic literature search was conducted using PubMed, EMBASE and Web of Science. Inclusion criteria consisted of studies that were peer reviewed, obtainable in English, used SVI as a measurement applied to EGS. Of the initial 1216 papers 11 studies met inclusion criteria.ResultsHigh SVI is associated with increased mortality, respiratory, cardiac and bleeding complications, and readmissions. Acute cholecystitis showed higher SVI linked to an increased likelihood of requiring emergent cholecystectomy. Investigations into bowel-related surgeries show connections between high SVI and increased stoma creation and likelihood of emergent operations.ConclusionThere is evidence of correlation between SVI and a variety of poor outcomes in emergency general surgery patient. This suggests that SVI can serve as an indicator of high risk patients as well as allow there to be inventions in specific communities to improve health care outcomes.

Quantifying Social Vulnerability and Its Impact on Health Care Delivery, Payment, and Performance

This Viewpoint advocates for the inclusion of social determinants of health and health-related social needs data into the electronic health record as a measure for improving provision of equitable surgical care.

Association between community distress and return to work after burn injury

INTRODUCTION

Community-level disadvantage is associated with reduced quality of life after burn injury. We evaluated the association between community-level disadvantage and return to work after burn injury.

METHODS

A multicenter burn injury database was queried from 1998-2021. Participants 18-65 years old with documented employment status and ZIP codes were included. Exposures were community distress (Distressed Communities Index, DCI), patient demographics, and burn characteristics. The primary outcome was odds of employment 6 months after burn injury using stepwise logistic regression models, first with patient-level variables, then DCI. An interaction term was included to evaluate the modification of DCI and post-injury employment by race.

RESULTS

1960 participants were included, with a median age of 39.2 years (IQR 29.2, 49.3); 81 % were White, 75 % male, and 74 % were working at the time of injury. Participants unemployed 6 months post-injury were more often older, female, non-White, and unemployed at injury, with larger burn sizes and longer hospitalizations. 59 % of participants unemployed at 6 months were employed at the time of injury. Residence in the highest distress ZIP codes was associated with 2.21 (95 % CI 1.39-3.52) odds of 6 month unemployment. Older age, larger burn size, more operations, Black race, and pre-injury unemployment were associated with the greatest odds of unemployment. The interaction between race and DCI was not statistically significant.

CONCLUSION

Patients from the highest distress communities have twice the odds of unemployment 6 months after injury. This association did not vary by race. Screening for DCI by ZIP code may be a useful tool to focus vocational rehabilitation resources.

Housing Instability and Outcomes Among Patients With Access-Sensitive Surgical Conditions

INTRODUCTION

Housing instability is a significant contributor to poor health but remains understudied among surgical patients. We evaluated the association between housing instability and rates of unplanned surgical procedures, as well as resultant health and financial outcomes, for patients with access-sensitive conditions.

METHODS

Using the Healthcare Cost and Utilization Project National Inpatient Sample, we identified patients who underwent one of four selected procedures for access-sensitive surgical conditions (abdominal aortic aneurysm repair, colectomy, incisional hernia repair, and lower extremity bypass). Housing status was determined using International Classification of Disease, 10th Revision, Clinical Modification codes Z59.0 (homelessness) and Z59.1 (lack of adequate housing). Risk-adjusted multivariable logistic regression compared outcomes between patients with and without housing instability.

RESULTS

Of 1,761,965 individuals admitted for access-sensitive surgical conditions, 2280 were experiencing housing instability. Housing-unstable individuals had more than four times the odds of undergoing unplanned surgery than housing-stable individuals (odds ratio 4.41, P < 0.001). Across all procedures, individuals with housing instability experienced longer lengths of stay (planned: 5 d versus 4 d, P < 0.001; unplanned: 8 d versus 7 d, P < 0.001) and higher costs per admission following planned surgery ($20,379 versus $18,152, P < 0.001) than housing-stable individuals. Housing-unstable individuals had lower odds of complications and in-hospital mortality following planned surgeries. No differences in morbidity or mortality were identified following unplanned surgeries.

CONCLUSIONS

Patients experiencing housing instability had higher odds of undergoing unplanned surgical procedures, had longer hospital stays and higher costs, and had similar or better outcomes following surgery. Efforts to expand affordable housing opportunities may improve access to timely surgical care.

Analyzing the Social Vulnerability Index With Metabolic Surgery

INTRODUCTION

The social vulnerability index (SVI) is a census tract-level population-based measure generated from 16 socioeconomic and demographic variables on a scale from 1 (least) to 100 (most) vulnerable. This study has three objectives as follows: 1) to analyze multiple ways of utilizing SVI, 2) compare SVI as a group measure of marginalization to individual markers, and 3) to understand how SVI is associated with choice of surgery in metabolic surgery.

METHODS

We retrospectively identified adults undergoing Roux-en-Y gastric bypass and gastric sleeve in 2013-2018 National Surgical Quality Improvement Program data from a single academic center. High SVI was defined as >75th percentile. Low SVI was coded as <75th percentile in measure 1 and < 25th percentile in measure 2. Chi-square and Mann-Whitney U tests were utilized for categorical and continuous variables, respectively. Multivariable regression models were performed comparing SVI to marginalized status as a predictor for type of metabolic surgery.

RESULTS

We identified 436 patients undergoing metabolic surgery, with a low overall morbidity (6.1%). Complication and readmission rates were similar across comparator groups. The logistic regression models had similar area under the curve, supporting SVI as a proxy for individual measures of marginalization.

CONCLUSIONS

SVI performed as well as marginalized status in predicting preoperative risk. This suggests the validity of using SVI to identify high risk patients. By providing a single, quantitative score encompassing many social determinants of health, SVI is a useful tool in identifying patients facing the greatest health disparities.

Neighborhood vulnerability and associations with poor health-related quality of life among adult survivors of childhood cancer

BACKGROUND

Few studies have investigated the relationship between neighborhood vulnerability and health-related quality of life (HRQOL) in the childhood cancer population. This study evaluated the impact of neighborhood vulnerability on HRQOL among adult survivors of childhood cancer.

METHODS

This cross-sectional study included 4393 adult survivors of childhood cancer from the St Jude Lifetime Cohort Study. At the baseline (2007-2020), HRQOL was assessed using the SF36v2's physical and mental components summaries (PCS and MCS). Neighborhood vulnerability was assessed using the overall, domain, and indicator-specific scores of the Social Vulnerability Index (SVI) and Minority Health SVI (MHSVI). Multivariable logistic regression was used to evaluate associations of neighborhood vulnerability (quartiles: Q1-Q4) with impaired HRQOL (1SD below the norm), adjusting for diagnosis, demographics, personal socioeconomic status (SES), lifestyle, and chronic health condition burden. Interactions of SVI and MHSVI with personal SES on impaired HRQOL were analyzed.

RESULTS

Among survivors, 51.9% were male, averaging 30.3 years of age at evaluation and 21.5 years since diagnosis. Comparing neighborhoods with higher vs lower vulnerability (Q4 vs Q1), overall (odds ratio [OR] = 1.60, 95% confidence interval [CI] = 1.19 to 2.16) and domain-specific vulnerability (socioeconomic: OR = 1.59, 95% CI = 1.18 to 2.15; household composition: OR = 1.54, 95% CI = 1.16 to 2.06; housing and transportation: OR = 1.33, 95% CI = 1.00 to 1.76; medical vulnerability: OR = 1.60, 95% CI = 1.22 to 2.09) were significantly associated with impaired PCS, but not MCS. Residing in neighborhoods lacking urgent care clinics was significantly associated with impaired PCS (OR = 1.39, 95% CI = 1.08 to 1.78). Having lower vs higher personal education and living in higher vulnerability neighborhoods were associated with more impaired PCS (Pinteraction = .021).

CONCLUSIONS

Specific aspects of neighborhood vulnerability increase the risk for impaired physical HRQOL. Addressing these neighborhood factors is essential to enhance the HRQOL of survivors.

The Most Socially Vulnerable Patients Benefit the Most Following Gender Affirming Facial Surgery

OBJECTIVE

While studies have shown that access to facial feminization surgery can be restricted by financial and geographic limitations, there is a lack of information on the impact of surgery on the most vulnerable patients. Therefore, this study assessed the impact of social vulnerability and neighborhood socioeconomic disadvantage on patient-reported outcomes after facial feminization surgery.

METHODS

Patients were surveyed pre and postoperatively using the FACE-Q Aesthetics Questionnaire and geo-coded using home addresses to obtain social vulnerability index (SVI) and Area Deprivation Index scores. Two sets of Pearson correlation values were calculated: (1) between SVI scores and each of the pre and postoperative FACE-Q modules and (2) between SVI scores and differences between pre and postoperative FACE-Q modules. Univariate linear regression analyses were performed for the latter. All analyses were repeated for Area Deprivation Index scores.

RESULTS

Twenty patients participated in this study. Postoperative facial appearance satisfaction positively correlated with total SVI (r = 0.48, P = 0.031), socioeconomic status theme (r=0.47, P=0.037), and racial and ethnic minority theme (r = 0.48, P = 0.031) scores. The difference between pre and postoperative facial appearance satisfaction positively correlated with total SVI (coefficient = 37.40, r = 0.47, P = 0.035), racial and ethnic minority theme (coefficient = 44.00, r = 0.46, P = 0.040), and housing type and transportation theme (coefficient = 46.97, r = 0.46, P = 0.042) scores.

CONCLUSION

Patients impacted by greater social vulnerability disproportionally experience the greatest benefit from gender-affirming facial surgery.

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

INTRODUCTION

Ventral hernias can be repaired electively; however, many circumstances require emergency repair. The association between sociodemographic status and rate of emergency repair are unclear and the Social Vulnerability Index may be a useful tool to better understanding this association. The purpose of this study was to investigate the association between Social Vulnerability Index and emergency ventral hernia repair.

METHODS

This was a retrospective cohort study using the National Surgical Quality Improvement Program (2012-2018) data for patients at a level 1 trauma center. We included patients who had an open ventral hernia repair. Social Vulnerability Index was based on residential address at the time of surgery. We conducted univariate and bivariate statistics, including χ2 and Mann-Whitney U tests to compare high and low social vulnerability.

RESULTS

Our sample had 1,017 patients. Patients who underwent emergency operations were older (P = .025) and had higher Social Vulnerability Index (P = .029). Patients in the high Social Vulnerability Index group were 1.5 times more likely to receive emergency surgery (P = .047). Emergency repair was also associated with increased frequency of nonhome discharge (9% vs 2%, P = .001) and higher mean work relative value unit (15.4 vs 11.9, P < .001).

CONCLUSION

Patients requiring emergency ventral hernia repair have significantly higher Social Vulnerability Index than those undergoing elective repair. This vulnerable population also has increased cost associated with the repair and higher rates of nonhome discharge. This work provides a foundation for efforts to reach patients in high Social Vulnerability Index environments at an earlier stage to achieve earlier elective repair.

Correlation of Patient-Reported Social Determinants of Health With Census Tract Measures of Socioeconomic Disadvantage in Patients With GI Cancers in Eastern North Carolina

PURPOSE

Investigating the impact of social determinants of health (SDOHs) on cancer care in large populations relies on census estimates. Routine clinic SDOH screening provides timely patient-level information which could inform best practices. This study evaluated the correlation between patient-reported SDOH needs and population-level census tract measures.

METHODS

This was a retrospective cross-sectional study of a cohort of adult patients with GI malignancy screened for SDOHs such as financial insecurity, transportation, and food insecurity during initial outpatient evaluation at East Carolina University (formerly Vidant) Health Medical Center in Greenville, NC (November 2020-July 2021). Primary outcomes included number and severity of identified SDOH needs and area deprivation index (ADI) and census tract measures for each patient. Spearman rank correlations were calculated among patient-level needs and between patient-level needs and similar census tract measures.

RESULTS

Of 112 patients screened, 58.9% self-identified as White (n = 66) and 41.1% as Black (n = 46). A total of 50.5% (n = 54) resided in a rural county. The collective median state ADI rank was 7 (IQR, 5-9). The median household income was $38,125 in US dollars (USD) (IQR, $31,436-$48,934 [USD]). Only 12.5% (n = 14) reported a moderate or severe financial need. Among reported needs, financial need moderately correlated with food insecurity (coefficient, 0.46; P < .001) and transportation (coefficient, 0.45; P < .001). Overall, census tract measures and reported needs poorly correlated. Lack of transportation correlated with percentage of households without a vehicle (coefficient, 0.18; P = .03) and limited access to healthy foods (coefficient, 0.18; P = .04).

CONCLUSION

Given the poor correlation between reported and census needs, population-level measures may not accurately predict patient-reported needs. These findings highlight the importance of SDOH screening in the clinical setting to reduce health disparities and identify opportunities to improve care delivery.

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.

Community-Level Disadvantage of Adults With Firearm- vs Motor Vehicle-Related Injuries

Importance

Motor vehicle crash (MVC) and firearm injuries are 2 of the top 3 mechanisms of adult injury-related deaths in the US.

Objective

To understand the differing associations between community-level disadvantage and firearm vs MVC injuries to inform mechanism-specific prevention strategies and appropriate postdischarge resource allocation.

Design, Setting, and Participants

This multicenter cross-sectional study analyzed prospectively collected data from the American College of Surgeons (ACS) Firearm Study. Included patients were treated either for firearm injury between March 1, 2021, and February 28, 2022, or for MVC-related injuries between January 1 and December 31, 2021, at 1 of 128 participating ACS trauma centers.

Exposures

Community distress.

Main outcome and Measure

Odds of presenting with a firearm as compared with MVC injury based on levels of community distress, as measured by the Distressed Communities Index (DCI) and categorized in quintiles.

Results

A total of 62 981 patients were included (mean [SD] age, 42.9 [17.7] years; 42 388 male [67.3%]; 17 737 Black [28.2%], 9052 Hispanic [14.4%], 36 425 White [57.8%]) from 104 trauma centers. By type, there were 53 474 patients treated for MVC injuries and 9507 treated for firearm injuries. Patients with firearm injuries were younger (median [IQR] age, 31.0 [24.0-40.0] years vs 41.0 [29.0-58.0] years); more likely to be male (7892 of 9507 [83.0%] vs 34 496 of 53 474 [64.5%]), identified as Black (5486 of 9507 [57.7%] vs 12 251 of 53 474 [22.9%]), and Medicaid insured or uninsured (6819 of 9507 [71.7%] vs 21 310 of 53 474 [39.9%]); and had a higher DCI score (median [IQR] score, 74.0 [53.2-94.8] vs 58.0 [33.0-83.0]) than MVC injured patients. Among admitted patients, the odds of presenting with a firearm injury compared with MVC injury were 1.50 (95% CI, 1.35-1.66) times higher for patients living in the most distressed vs least distressed ZIP codes. After controlling for age, sex, race, ethnicity, and payer type, the DCI components associated with the highest adjusted odds of presenting with a firearm injury were a high housing vacancy rate (OR, 1.11; 95% CI, 1.04-1.19) and high poverty rate (OR, 1.17; 95% CI, 1.10-1.24). Among patients sustaining firearm injuries patients, 4333 (54.3%) received no referrals for postdischarge rehabilitation, home health, or psychosocial services.

Conclusions and Relevance

In this cross-sectional study of adults with firearm- and motor vehicle-related injuries, we found that patients from highly distressed communities had higher odds of presenting to a trauma center with a firearm injury as opposed to an MVC injury. With two-thirds of firearm injury survivors treated at trauma centers being discharged without psychosocial services, community-level measures of disadvantage may be useful for allocating postdischarge care resources to patients with the greatest need.

Where you live matters: Area deprivation predicts poor survival and liver transplant waitlisting

Social determinants of health (SDOH) are important predictors of poor clinical outcomes in chronic diseases, but their associations among the general cirrhosis population and liver transplantation (LT) are limited. We conducted a retrospective, multiinstitutional analysis of adult (≥18-years-old) patients with cirrhosis in metropolitan Chicago to determine the associations of poor neighborhood-level SDOH on decompensation complications, mortality, and LT waitlisting. Area deprivation index and covariates extracted from the American Census Survey were aspects of SDOH that were investigated. Among 15 101 patients with cirrhosis, the mean age was 57.2 years; 6414 (42.5%) were women, 6589 (43.6%) were non-Hispanic White, 3652 (24.2%) were non-Hispanic Black, and 2662 (17.6%) were Hispanic. Each quintile increase in area deprivation was associated with poor outcomes in decompensation (sHR [subdistribution hazard ratio] 1.07; 95% CI 1.05-1.10; P < .001), waitlisting (sHR 0.72; 95% CI 0.67-0.76; P < .001), and all-cause mortality (sHR 1.09; 95% CI 1.06-1.12; P < .001). Domains of SDOH associated with a lower likelihood of waitlisting and survival included low income, low education, poor household conditions, and social support (P < .001). Overall, patients with cirrhosis residing in poor neighborhood-level SDOH had higher decompensation, and mortality, and were less likely to be waitlisted for LT. Further exploration of structural barriers toward LT or optimizing health outcomes is warranted.

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

Background

The association of social vulnerability (SV) and cardiac transplant survival remains poorly defined, particularly related to long-term outcomes. The purpose of this study was to define the impact of SV on survival among heart transplant recipients with at least 1 year of survival post-transplant.

Methods

Heart transplant recipients were identified using the United Network for Organ Sharing database between June 1, 2006, and December 31, 2020. The Center for Disease Control's Social Vulnerability Index (SVI) database was used to stratify patients based on SVI into 3 groups: low: <25; average: 26 to 74; high: 75+. The groups were analyzed with comparative statistics, and unadjusted survival was assessed using Kaplan-Meier methods. To determine the independent association between SVI and survival, a multivariable Cox proportional hazard model was created.

Results

There were 27,740 recipients identified. High SVI patients more commonly identified as Black individuals and had a higher incidence of diabetes, pretransplant intensive care unit admission, and need for concomitant kidney transplant (p < 0.05 for all). Additionally, high SVI patients had the longest length of stay post-transplant (21.4 days) (p < 0.05). High and average SVI patients had inferior 3-year, 5-year, and 10-year survival vs low SVI patients (p < 0.05). After adjustment, average (hazard ratio [HR]: 1.12) and high (HR: 1.16) SVI were independently associated with an increased risk of mortality on multivariable analysis (both p < 0.001).

Conclusion

High or average SVI is independently associated with increased mortality following heart transplantation in patients with 1-year conditional survival. These findings demonstrate that disparities persist among heart transplant recipients during long-term follow-up.

Using the Social Vulnerability Index to Analyze Statewide Health Disparities in Cholecystectomy

INTRODUCTION

Addressing the effects of social determinants of health in surgery has become a national priority. We evaluated the utility of the Social Vulnerability Index (SVI) in determining the likelihood of receiving cholecystectomy for cholecystitis in Texas.

METHODS

A retrospective study of adults with cholecystitis in the Texas Hospital Inpatient Discharge Public Use Data File and Texas Outpatient Surgical and Radiological Procedure Data Public Use Data File from 2016 to 2019. Patients were stratified into SVI quartiles, with the lowest quartile as low vulnerability, the middle two as average vulnerability, and the highest as high vulnerability. The relative risk (RR) of undergoing surgery was calculated using average vulnerability as the reference category and subgroup sensitivity analyses.

RESULTS

A total of 67,548 cases were assessed, of which 48,603 (72.0%) had surgery. Compared with the average SVI groups, the low vulnerability groups were 21% more likely to undergo cholecystectomy (RR = 1.21, 95% confidence interval [CI] 1.18-1.24), whereas the high vulnerability groups were 9% less likely to undergo cholecystectomy (RR = 0.91, 95% CI 0.88-0.93). The adjusted model showed similar results (RR = 1.05, 95% CI 1.04-1.06 and RR = 0.97, 95% CI 0.96-0.99, for low and high vulnerability groups, respectively). These results remained significant after stratifying for age, sex, ethnicity, and insurance status. However, the differences between low, average, and high vulnerability groups diminished in rural settings, with lower surgery rates in all groups.

CONCLUSIONS

Patients with higher SVI were less likely to receive an elective cholecystectomy. SVI is an effective method of identifying social determinants impacting access to and receipt of surgical care.

The impact of social vulnerability index on survival following autologous stem cell transplant for multiple myeloma

Autologous hematopoietic stem cell transplantation (ASCT) is the standard of care for eligible patients with multiple myeloma (MM) to prolong progression-free survival (PFS). While several factors affect survival following ASCT, the impact of social determinants of health such as the CDC Social Vulnerability Index (SVI) is not well documented. This single-center retrospective analysis evaluated the impact of SVI on PFS following ASCT in MM patients. 225 patients with MM who underwent ASCT participated, with 51% transplanted in the last 5 years. At 5 years post-transplant, 55 (50%) achieved PFS and 66 (60%) remained alive. Higher SVI values were significantly associated with lower odds of PFS (OR = 0.521, p < 0.01, 95% CI [0.41, 0.66]) and OS (OR = 0.592, p < 0.01, 95% CI [0.46, 0.76]) post-transplant. Greater vulnerability scores in the socioeconomic status (OR = 0.890; 95% CI: [0.82, 0.96]), household characteristics (OR = 0.912; 95% CI: [0.87, 0.95]), and racial and ethnic minority status (OR = 0.854; 95% CI: [0.81, 0.90]) themes significantly worsened the odds of PFS. These results suggest high SVI areas may need more resources to achieve optimal PFS and OS. Future studies will focus on addressing factors within the socioeconomic status, household characteristics, and racial and ethnic minority subthemes, as these have a more pronounced effect on PFS.

The Utility of the Area Deprivation Index in Assessing Complications After Total Joint Arthroplasty

Background

Vulnerable populations, including patients from a lower socioeconomic status, are at an increased risk for infection, revision surgery, mortality, and complications after total joint arthroplasty (TJA). An effective metric to quantify and compare these populations has not yet been established in the literature. The Area Deprivation Index (ADI) provides a composite area-based indicator of socioeconomic disadvantage consisting of 17 U.S. Census indicators, based on education, employment, housing quality, and poverty. We assessed patient risk factor profiles and performed multivariable regressions of total complications at 30 days, 90 days, and 1 year.

Methods

A prospectively collected database of 3,024 patients who underwent primary elective total knee arthroplasty or total hip arthroplasty performed by 3 fellowship-trained orthopaedic surgeons from January 1, 2015, through December 31, 2021, at a tertiary health-care center was analyzed. Patients were divided into quintiles (ADI ≤20 [n = 555], ADI 21 to 40 [n = 1,001], ADI 41 to 60 [n = 694], ADI 61 to 80 [n = 396], and ADI 81 to 100 [n = 378]) and into groups based on the national median ADI, ≤47 (n = 1,896) and >47 (n = 1,128).

Results

Higher quintiles had significantly more females (p = 0.002) and higher incidences of diabetes (p < 0.001), congestive heart failure (p < 0.001), chronic obstructive pulmonary disease (p < 0.001), hypertension (p < 0.001), substance abuse (p < 0.001), and tobacco use (p < 0.001). When accounting for several confounding variables, all ADI quintiles were not associated with increased total complications at 30 days, but age (p = 0.023), female sex (p = 0.019), congestive heart failure (p = 0.032), chronic obstructive pulmonary disease (p = 0.001), hypertension (p = 0.003), and chronic kidney disease (p = 0.010) were associated. At 90 days, ADI > 47 (p = 0.040), female sex (p = 0.035), and congestive heart failure (p = 0.001) were associated with increased total complications.

Conclusions

Balancing intrinsic factors, such as patient demographic characteristics, and extrinsic factors, such as social determinants of health, may minimize postoperative complications following TJA. The ADI is one tool that can account for several extrinsic factors, and can thus serve as a starting point to improving patient education and management in the setting of TJA.

Associations of geographic-based socioeconomic factors and HPV vaccination among male and female children in five US states

BACKGROUND

We assessed whether five geographic-based socioeconomic factors (medically underserved area (MUA); healthcare provider shortage area (HPSA); persistent poverty; persistent child poverty; and social vulnerability index (SVI)) were associated with the odds of HPV vaccination initiation, series completion, and parental vaccine hesitancy, and whether the observed relationships varied by gender of the child.

METHODS

An online panel service, administered through Qualtrics®, was used to recruit parents of adolescents 9-17 years of age to complete a one-time survey in 2021. Coverage of the panel included five US states: Arkansas, Mississippi, Missouri, Tennessee, and Southern Illinois. Generalized estimating equation (GEE) models were used to assess population-level associations between five geographic-based socioeconomic factors (MUA; HPSA; persistent poverty; persistent child poverty; and SVI) and three HPV vaccination outcomes (initiation, series completion, and hesitancy). All GEE models were adjusted for age of child and clustering at the state level.

RESULTS

Analyses were conducted using responses from 926 parents about their oldest child in the target age range (9-17 years). The analytic sample consisted of 471 male children and 438 female children across the five states. In adjusted GEE models, persistent child poverty and HPSA were negatively associated with HPV vaccination initiation and series completion among female children, respectively. Among male children, high social vulnerability was negatively associated with HPV vaccine series completion. Additionally, persistent poverty and high social vulnerability were negatively associated with HPV vaccine hesitancy in male children.

CONCLUSIONS

The results of this cross-sectional study suggest that geographic-based socioeconomic factors, particularly, HPSA, persistent poverty, and SVI, should be considered when implementing efforts to increase HPV vaccine coverage for adolescents. The approaches to targeting these geographic factors should also be evaluated in future studies to determine if they need to be tailored for male and female children.

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 interaction between geriatric and neighborhood vulnerability: Delineating prehospital risk among older adult emergency general surgery patients

BACKGROUND

When presenting for emergency general surgery (EGS) care, older adults frequently experience increased risk of adverse outcomes owing to factors related to age ("geriatric vulnerability") and the social determinants of health unique to the places in which they live ("neighborhood vulnerability"). Little is known about how such factors collectively influence adverse outcomes. We sought to explore how the interaction between geriatric and neighborhood vulnerability influences EGS outcomes among older adults.

METHODS

Older adults, 65 years or older, hospitalized with an AAST-defined EGS condition were identified in the 2016 to 2019, 2021 Florida State Inpatient Database. Latent variable models combined the influence of patient age, multimorbidity, and Hospital Frailty Risk Score into a single metric of "geriatric vulnerability." Variations in geriatric vulnerability were then compared across differences in "neighborhood vulnerability" as measured by variations in Area Deprivation Index, Social Vulnerability Index, and their corresponding subthemes (e.g., access to transportation).

RESULTS

A total of 448,968 older adults were included. For patients living in the least vulnerable neighborhoods, increasing geriatric vulnerability resulted in up to six times greater risk of death (30-day risk-adjusted hazards ratio [HR], 6.32; 95% confidence interval [CI], 4.49-8.89). The effect was more than doubled among patients living in the most vulnerable neighborhoods, where increasing geriatric vulnerability resulted in up to 15 times greater risk of death (30-day risk-adjusted HR, 15.12; 95% CI, 12.57-18.19). When restricted to racial/ethnic minority patients, the multiplicative effect was four-times as high, resulting in corresponding 30-day HRs for mortality of 11.53 (95% CI, 4.51-29.44) versus 40.67 (95% CI, 22.73-72.78). Similar patterns were seen for death within 365 days.

CONCLUSION

Both geriatric and neighborhood vulnerability have been shown to affect prehospital risk among older patients. The results of this study build on that work, presenting the first in-depth look at the powerful multiplicative interaction between these two factors. The results show that where a patient resides can fundamentally alter expected outcomes for EGS care such that otherwise less vulnerable patients become functionally equivalent to those who are, at baseline, more aged, more frail, and more sick.

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.

Geospatial Analysis of Social Vulnerability, Race, and Firearm Violence in Chicago

INTRODUCTION

Urban firearm violence (UFV) is associated with inequities rooted in structural racism and socioeconomic disparities. Social vulnerability index (SVI) is a composite measure that encompasses both. We sought to understand the relationship between SVI and the incidence of UFV in Chicago using geospatial analysis for the first time.

MATERIALS AND METHODS

Firearm assaults in Chicago 2001-2019 were obtained from the Trace. Locations of incidents were geocoded using ArcGIS and overlaid with census tract vector files. These data were linked to 2018 SVI measures obtained from the Center for Disease Control and Prevention. Shooting rates were calculated by tabulating the total number of shootings per capita in each census tract. We used Poisson regression with robust error variance to estimate the incident rate of UFV in different levels of social vulnerability and Local Moran's I to evaluate spatial autocorrelation.

RESULTS

In total, 642 census tracts were analyzed. The median shooting rate was 2.6 per 1000 people (interquartile 0.77, 7.0). When compared to those census tracts with very low SVI, census tracts with low SVI had a 1.7-time increased incident rate of shootings (incidence rate ratio [IRR] 1.74, 95% CI 1.08, 2.81), tracts with moderate SVI had a 3.1-time increased incident rate (IRR 3.07, 95% CI 2.31, 4.10), and tracts with high SVI had a 7-time increased incident rate (IRR 7.03, 95% CI 5.45, 9.07).

CONCLUSIONS

In Chicago, social vulnerability has a significant association with rates of firearm violence, providing a focus point for policy intervention to address high rates of interpersonal violence in similar cities.

Modification of Firearm Law-Firearm Injury Association by Economic Disadvantage

INTRODUCTION

Firearm-related injuries in the U.S. have risen 37% since 2015. Understanding how the association between firearm incidents and state-level firearm restrictiveness is modified by community-level distress and economic connectedness (EC) may inform upstream injury prevention efforts.

METHODS

A national cross-sectional study of firearm incidents (interpersonal and unintentional firearm events) occurring between 1/2015 and 12/2021 was performed using the Gun Violence Archive. The exposures were community distress (Distressed Communities Index, DCI), EC, and year-state-level firearm restrictiveness. The primary outcome was mean annual urban firearm incidence rate per ZIP Code Tabulation Area. Generalized linear mixed models were fit to evaluate the modification of the firearm law-firearm incident association by DCI and EC. Data analyses took place in 2022.

RESULTS

About 266,020 firearm incidents were included. The mean rate was higher with each DCI tertile, with a RR of 3.18 (95% CI: 3.06, 3.30) in high versus low distress communities. Low EC was associated with over 1.8 times greater rate of firearm-related injury. The least restrictive firearm laws were associated with 1.20 times higher risk of firearm incidents (95% CI: 1.12, 1.28). The association between restrictive laws and lower incidence rates was strongest in low and medium distress and high EC communities.

CONCLUSIONS

Stricter firearm laws are associated with lower rate of firearm incidents. The magnitude of this association is smallest for communities experiencing the greatest economic disadvantage.

Impact of Neighborhood Deprivation and Social Vulnerability on Outcomes and Interventions in Patients with Cleft Palate

OBJECTIVE

To examine whether neighborhood disadvantage impacts length of follow-up, interventions, and outcomes for patients with cleft palate.

DESIGN

Retrospective cohort.

SETTING

Cleft Palate Craniofacial Institute Database at St. Louis Children's Hospital.

PATIENTS/PARTICIPANTS

Patients with cleft palate following in St. Louis Children's Hospital Cleft Palate Multidisciplinary Team Clinic.

INTERVENTIONS

Primary palatoplasty between 2012-2017. Patients were divided into quartiles across area deprivation index (ADI) and social vulnerability index (SVI), two validated, composite metrics of neighborhood disadvantage, to examine whether living in neighborhoods from different deprivation quartiles impacts outcomes of interest.

MAIN OUTCOME MEASURE

Follow-up through age 5, surgeries and surgical complications, speech, developmental, and behavioral outcomes.

RESULTS

205 patients were included. 39% of patients belonged to the most deprived ADI quartile, while 15% belonged to the most vulnerable SVI quartile. There were no differences between ADI or SVI quartiles in number of operations received (p ≥ 0.40). Patients in the most deprived ADI quartile were significantly more likely to have speech/language concerns (OR 2.32, 95% CI [1.20-4.89], p = 0.01). Being in a more vulnerable SVI quartile was associated with developmental delay (OR 2.29, 95% CI [1.04-5.15], p = 0.04). ADI and SVI quartile did not impact risk of loss to follow-up in the isolated and combined cleft lip and palate subgroups (p ≥ 0.21).

CONCLUSIONS

Neighborhood disadvantage impacts speech and developmental outcomes in patients with cleft palate despite comparable length of follow-up in multidisciplinary team clinic.

Gender, racial, and socioeconomic disparity of preoperative optimization goals in ventral hernia repair

BACKGROUND

Preoperative optimization cut-offs are frequently utilized to determine eligibility for elective ventral hernia repair. Our objective was to assess the relationship between gender, race, and socioeconomic status and preoperative optimization goals.

METHODS

We queried our institutional database for adults with ventral hernia diagnoses between 2016 and 2021. Demographics, comorbidities, laboratory, and operative data were collected and analyzed. The following cut-offs were used to determine eligibility for elective repair: body mass index (BMI) < 40 kg/m2, no active smoking, and glycated hemoglobin (HbA1c) < 8%. Socioeconomic status was assessed using the Distressed Communities Index.

RESULTS

A total of 5638 patients were included [Whites = 4321 (77%), Blacks = 794 (14%), Hispanics = 318 (6%), and other/unknown 205 (4%)]. Median age was 61 years and 50% were male. Most common hernia types were umbilical (36%) and incisional (20%). 10% had BMI > 40 kg/m2, 9% were active smokers and 4% had HbA1c > 8%. 21% of all patients did not meet the preoperative optimization cut-offs at time of diagnosis and those were less likely to undergo hernia repair during the study timeframe compared to those who did (OR 0.50; 95% CI [0.42-0.60]). There was a higher proportion of females (21%) and Blacks (22%) with BMI > 40 kg/m2 compared to males (11%) and other races (11-15%), p = 0.002. As the level of socioeconomic distress increased, there was a corresponding increase in the proportion of patients who did not meet preoperative optimization cut-offs from 16% in prosperous communities to 25% in distressed communities (p < 0.0001).

CONCLUSION

Nearly 1 of 5 patients with ventral hernias is affected by commonly used arbitrary preoperative optimization cut-offs. These cut-offs disproportionately impact females, Black patients and those with higher socioeconomic distress. These disparities need to be considered when planning preoperative optimization protocols and resource allocation to ensure equitable access to elective ventral hernia repair.

Distressed community index as a predictor of presentation and postoperative outcomes in ventral hernia repair

BACKGROUND

We evaluated the impact of socioeconomic status on presentation, management, and outcomes of ventral hernias.

METHODS

The Abdominal Core Health Quality Collaborative was queried for adult patients undergoing ventral hernia repair. Socioeconomic quintiles were assigned using the Distressed Community Index (DCI): prosperous (0-20), comfortable (21-40), mid-tier (41-60), at-risk (61-80), and distressed (81-100). Outcomes included presenting symptoms, urgency, operative details, 30-day outcomes, and one-year hernia recurrence rates. Multivariable regression evaluated 30-day wound complications.

RESULTS

39,494 subjects were identified; 32,471 had zip codes (82.2%).Urgent presentation (3.6% vs. 2.3%) and contaminated cases (0.83% vs. 2.06%) were more common in the distressed group compared to the prosperous group (p < 0.001). Higher DCI correlated with readmission (distressed: 4.7% vs prosperous: 2.9%,p < 0.001) and reoperation (distressed 1.8% vs prosperous: 0.92%,p < 0.001). Wound complications were independently associated with increasing DCI (p < 0.05). Clinical recurrence rates were similar at one-year (distressed: 10.4% vs prosperous: 8.6%, p = 0.54).

CONCLUSIONS

Inequity exists in presentation and perioperative outcomes for ventral hernia repair and efforts should be focused on increasing access to elective surgery and improving postoperative wound care.

Race Associated With Increased Complication Rates After Total Knee Arthroplasty

BACKGROUND

Racial and ethnic disparities have been suggested to be associated with poor outcomes after total knee arthroplasty (TKA). While socioeconomic disadvantage has been studied, analyses of race as the primary variable are lacking. Therefore, we examined the potential differences between Black and White TKA recipients. Specifically, we assessed 30-day and 90-day, as well as 1 year: (1) emergency department visits and readmissions; (2) total complications; (3) as well as risk factors for total complications.

METHODS

A consecutive series of 1,641 primary TKAs from January 2015 to December 2021 at a tertiary health care system were reviewed. Patients were stratified according to race, Black (n = 1,003) and White (n = 638). Outcomes of interest were analyzed using bivariate Chi-square and multivariate regressions. Demographic variables such as sex, American Society of Anesthesiologists classification, diabetes, congestive heart failure, chronic pulmonary disease, and socioeconomic status based on Area Deprivation Index were controlled for across all patients.

RESULTS

The unadjusted analyses found that Black patients had an increased likelihood of 30-day emergency department visits and readmissions (P < .001). However, in the adjusted analyses, Black race was demonstrated to be a risk factor for increased total complications at all-time points (P ≤ .0279). Area Deprivation Index was not a risk for cumulative complications at these time points (P ≥ .2455).

CONCLUSION

Black patients undergoing TKA may be at increased risk for complications with more risk factors including higher body mass index, tobacco use, substance abuse, chronic obstructive pulmonary disease, congestive heart failure, hypertension, chronic kidney disease, and diabetes and were thus, "sicker" initially than the White cohort. Surgeons are often treating these patients at the later stages of their diseases when risk factors are less modifiable, which necessitates a shift to early, preventable public health measures. While higher socioeconomic disadvantage has been associated with higher rates of complications, the results of this study suggest that race may play a greater role than previously thought.

Importance of social vulnerability on long-term outcomes after heart transplantation

The relationship between social determinants of health and outcomes after heart transplantation has not been examined. The social vulnerability index (SVI) uses United States census data to determine the social vulnerability of every census tract based on 15 factors. This retrospective study seeks to examine the impact of SVI on outcomes after heart transplantation. Adult heart recipients who received a graft between 2012 and 2021 were stratified into SVI percentiles of <75% and SVI of ≥75%. The primary endpoint was survival. The median SVI was 48% (interquartile range: 30%-67%) among 23 700 recipients. One-year survival was similar between groups (91.4 vs 90.7%, log-rank P = .169); however, 5-year survival was lower among individuals living in vulnerable communities (74.8% vs 80.0%, P < .001). This finding persisted despite risk adjustment for other factors associated with mortality (survival time ratio 0.819, 95% confidence interval: 0.755-0.890, P < .001). The incidences of 5-year hospital readmission (81.4% vs 75.4%, P < .001) and graft rejection (40.3% vs 35.7%, P = .004) were higher among individuals living in vulnerable communities. Individuals living in vulnerable communities may be at increased risk of mortality after heart transplantation. These findings suggest there is an opportunity to focus on these recipients undergoing heart transplantation to improve survival.

Neighborhood environmental vulnerability and pediatric asthma morbidity in US metropolitan areas

BACKGROUND

Research suggests demographic, economic, residential, and health-related factors influence vulnerability to environmental exposures. Greater environmental vulnerability may exacerbate environmentally related health outcomes. We developed a neighborhood environmental vulnerability index (NEVI) to operationalize environmental vulnerability on a neighborhood level.

OBJECTIVE

We explored the relationship between NEVI and pediatric asthma emergency department (ED) visits (2014-19) in 3 US metropolitan areas: Los Angeles County, Calif; Fulton County, Ga; and New York City, NY.

METHODS

We performed separate linear regression analyses examining the association between overall NEVI score and domain-specific NEVI scores (demographic, economic, residential, health status) with pediatric asthma ED visits (per 10,000) across each area.

RESULTS

Linear regression analyses suggest that higher overall and domain-specific NEVI scores were associated with higher annual pediatric asthma ED visits. Adjusted R2 values suggest that overall NEVI scores explained at least 40% of the variance in pediatric asthma ED visits. Overall NEVI scores explained more of the variance in pediatric asthma ED visits in Fulton County. NEVI scores for the demographic, economic, and health status domains explained more of the variance in pediatric asthma ED visits in each area compared to the NEVI score for the residential domain.

CONCLUSION

Greater neighborhood environmental vulnerability was associated with greater pediatric asthma ED visits in each area. The relationship differed in effect size and variance explained across the areas. Future studies can use NEVI to identify populations in need of greater resources to mitigate the severity of environmentally related outcomes, such as pediatric asthma.

Unmet Social Health Needs as a Driver of Inequitable Outcomes After Surgery: A Cross-sectional Analysis of the National Health Interview Survey

OBJECTIVE

This study aims to identify opportunities to improve surgical equity by evaluating unmet social health needs by race, ethnicity, and insurance type.

BACKGROUND

Although inequities in surgical care and outcomes based on race, ethnicity, and insurance have been well documented for decades, underlying drivers remain poorly understood.

METHODS

We used the 2008-2018 National Health Interview Survey to identify adults age 18 years and older who reported surgery in the past year. Outcomes included poor health status (self-reported), socioeconomic status (income, education, employment), and unmet social health needs (food, housing, transportation). We used logistic regression models to progressively adjust for the impact of patient demographics, socioeconomic status, and unmet social health needs on health status.

RESULTS

Among a weighted sample of 14,471,501 surgical patients, 30% reported at least 1 unmet social health need. Compared with non-Hispanic White patients, non-Hispanic Black, and Hispanic patients reported higher rates of unmet social health needs. Compared with private insurance, those with Medicaid or no insurance reported higher rates of unmet social health needs. In fully adjusted models, poor health status was independently associated with unmet social health needs: food insecurity [adjusted odds ratio (aOR)=2.14; 95% confidence interval (CI): 1.89-2.41], housing instability (aOR=1.69; 95% CI: 1.51-1.89), delayed care due to lack of transportation (aOR=2.58; 95% CI: 2.02-3.31).

CONCLUSIONS

Unmet social health needs vary significantly by race, ethnicity, and insurance, and are independently associated with poor health among surgical populations. As providers and policymakers prioritize improving surgical equity, unmet social health needs are potential modifiable targets.

The social vulnerability index as a risk stratification tool for health disparity research in cancer patients: a scoping review

PURPOSE

The social vulnerability index (SVI), developed by the Centers for Disease Control and Prevention, is a novel composite measure encompassing multiple variables that correspond to key social determinants of health. The objective of this review was to investigate innovative applications of the SVI to oncology research and to employ the framework of the cancer care continuum to elucidate further research opportunities.

METHODS

A systematic search for relevant articles was performed in five databases from inception to 13 May 2022. Included studies applied the SVI to analyze outcomes in cancer patients. Study characteristics, patent populations, data sources, and outcomes were extracted from each article. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

RESULTS

In total, 31 studies were included. Along the cancer care continuum, five applied the SVI to examine geographic disparities in potentially cancer-causing exposures; seven in cancer diagnosis; fourteen in cancer treatment; nine in treatment recovery; one in survivorship care; and two in end-of-life care. Fifteen examined disparities in mortality.

CONCLUSION

In highlighting place-based disparities in patient outcomes, the SVI represents a promising tool for future oncology research. As a reliable geocoded dataset, the SVI may inform the development and implementation of targeted interventions to prevent cancer morbidity and mortality at the neighborhood level.

The Effect of Socioeconomic Disparity on Improvement in QuickDASH at 3 Months after Carpal Tunnel Release

The primary objective of this study was to determine the association between socioeconomic disparity and improvement in QuickDASH score 3 months after carpal tunnel release (CTR). The secondary objectives of this study were to determine the association between socioeconomic disparity and baseline preoperative QuickDASH score and 3 months postoperative QuickDASH score after CTR.

Methods

A single-institutional, prospective, longitudinal study was performed of 85 patients who underwent isolated, unilateral CTR for idiopathic carpal tunnel syndrome. Sixty-three patients (74%) who completed patient-reported outcome measures at 3 months after surgery comprised our study cohort. Socioeconomic disparity was assessed using the zip code level Distressed Communities Index (DCI) and the neighborhood level Area Deprivation Index. The outcome variables were the improvement in the QuickDASH score, 3 months postoperative QuickDASH score, and the preoperative QuickDASH score. Associations between continuous variables were assessed using simple linear regression.

Results

The mean DCI of the study cohort was in the 23rd national percentile, and the mean Area Deprivation Index was in the 15th national percentile. The mean preoperative QuickDASH of the study cohort was 49.3. The mean 3 months postoperative QuickDASH of the study cohort was 29.8. The mean improvement in QuickDASH at 3 months after surgery was 19.5, which was statistically significant and clinically meaningful. Area Deprivation Index and DCI were not associated with improvement in QuickDASH score or 3 months postoperative QuickDASH score. Higher DCI was associated with poorer baseline preoperative QuickDASH score.

Conclusion

Patients of various socioeconomic backgrounds can expect similar short-term improvements in symptoms and function after CTR.

Sex-based analysis of characteristics contributing to anorectal abscesses requiring acute care surgery

Background

Males present more frequently with anorectal abscesses than females. Factors contributing to this difference are not clear. The purpose of this study is to evaluate comorbidities and demographic features at presentation that may contribute to the male predominance in this disease process.

Methods

This is a retrospective study on patients who underwent acute care surgery for anorectal abscess at an urban safety-net hospital from 2015 to 2020. Bivariate analysis was used to determine factors associated with the sex difference in anorectal abscesses requiring acute care surgery.

Results

This study included 208 patients, of which 160 were male (76.9%). At the time of surgery, males had a higher rate of current tobacco use compared to females (25.6% vs. 8.3%, p = 0.009). Additionally, males who presented for surgery were older compared to females, (42.5 ± 10.8 years vs. 37.2 ± 13.4 years, p = 0.005). No differences were found between males and females with respect to comorbidities including diabetes, hypertension, body mass index (BMI), cardiovascular disease, or end stage renal disease.

Conclusion

This study suggests that the male predominance in anorectal abscess necessitating acute care surgery may be partially explained by current tobacco use and older age.

Social Determinants of Health and Quality of Life in Endocrine Surgery Patients

INTRODUCTION

Quality of life (QoL) of endocrine surgery patients is an important patient outcome but the role of social determinants of health (SDH) on preoperative QoL is understudied.

METHODS

This study used preoperative data of 233 endocrine surgery patients participating in a longitudinal QoL study to examine the influence of SDH (patient-level and environmental) on preoperative QoL. Patient-level SDH was assessed with structured survey questions and environmental SDH with the Social Vulnerability Index. Multiple domains of QoL were assessed with the Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29).

RESULTS

The average age of the sample was 52.9 y and 76.8% were female, 10% were Hispanic, 55.8% were White, 32.6% were Black, 6.9% were Other, and 4.7% were Asian. Patients with patient-level SDH were more likely to have worse preoperative QoL in multiple PROMIS domains. Patients who lived in the most socially vulnerable areas had the same or better QoL scores in the PROMIS-29 domains than those living in less vulnerable areas. Minority race patients were more likely to have patient-level SDH and to live in the most vulnerable areas.

CONCLUSIONS

This study is the first to our knowledge to examine the role of patient-level and environmental SDH on preoperative QoL among endocrine surgery patients. The results identified specific patient-level factors that could be used as the basis for interventions aimed to improve patients' QoL. Future studies that evaluate the role of preoperative SDH on long-term QoL and clinical outcomes would further enhance our understanding of the impact of SDH on patient wellbeing.

Social Vulnerability and Emergency General Surgery among Medicare Beneficiaries

BACKGROUND

Although the Social Vulnerability Index (SVI) was created to identify vulnerable populations after unexpected natural disasters, its ability to identify similar groups of patients undergoing unexpected emergency surgical procedures is unknown. We sought to examine the association between SVI and outcomes after emergency general surgery.

STUDY DESIGN

This study is a cross-sectional review of 887,193 Medicare beneficiaries who underwent 1 of 4 common emergency general surgery procedures (appendectomy, cholecystectomy, colectomy, and ventral hernia repair) performed in the urgent or emergent setting between 2014 and 2018. These data were merged with the SVI at the census-track level of residence. Risk-adjusted outcomes (30-day mortality, serious complications, readmission) were evaluated using a logistic regression model accounting for age, sex, comorbidity, year, procedure type, and hospital characteristics between high and low social vulnerability quintiles and within the 4 SVI subthemes (socioeconomic status; household composition and disability; minority status and language; and housing type and transportation).

RESULTS

Compared with beneficiaries with low social vulnerability, Medicare beneficiaries living in areas of high social vulnerability experienced higher rates of 30-day mortality (8.56% vs 8.08%; adjusted odds ratio 1.07; p < 0.001), serious complications (20.71% vs 18.40%; adjusted odds ratio 1.17; p < 0.001), and readmissions (16.09% vs 15.03%; adjusted odds ratio 1.08; p < 0.001). This pattern of differential outcomes was present in subgroup analysis of all 4 SVI subthemes but was greatest in the socioeconomic status and household composition and disability subthemes.

CONCLUSIONS

National efforts to support patients with high social vulnerability from natural disasters may be well aligned with efforts to identify communities that are particularly vulnerable to worse postoperative outcomes after emergency general surgery. Policies targeting structural barriers related to household composition and socioeconomic status may help alleviate these disparities.

Quality care is equitable care: a call to action to link quality to achieving health equity within acute care surgery

Health equity is defined as the sixth domain of healthcare quality. Understanding health disparities in acute care surgery (defined as trauma surgery, emergency general surgery and surgical critical care) is key to identifying targets that will improve outcomes and ensure delivery of high-quality care within healthcare organizations. Implementing a health equity framework within institutions such that local acute care surgeons can ensure equity is a component of quality is imperative. Recognizing this need, the AAST (American Association for the Surgery of Trauma) Diversity, Equity and Inclusion Committee convened an expert panel entitled 'Quality Care is Equitable Care' at the 81st annual meeting in September 2022 (Chicago, Illinois). Recommendations for introducing health equity metrics within health systems include: (1) capturing patient outcome data including patient experience data by race, ethnicity, language, sexual orientation, and gender identity; (2) ensuring cultural competency (eg, availability of language services; identifying sources of bias or inequities); (3) prioritizing health literacy; and (4) measuring disease-specific disparities such that targeted interventions are developed and implemented. A stepwise approach is outlined to include health equity as an organizational quality indicator.

Use Of Area-Based Socioeconomic Deprivation Indices: A Scoping Review And Qualitative Analysis

There is considerable interest among researchers, clinicians, and policy makers in understanding the impact of place on health. In this scoping review and qualitative analysis, we sought to assess area-level socioeconomic deprivation indices used in public health and health outcomes research in the US. We conducted a systematic scoping review to identify area-level socioeconomic deprivation indices commonly used in the US since 2015. We then qualitatively compared the indices based on the input-variable domains, data sources, index creation characteristics, index accessibility, the geography over which the index is applied, and the nature of the output measure or measures. We identified fifteen commonly used indices of area-level socioeconomic deprivation. There were notable differences in the characteristics of each index, particularly in how they define socioeconomic deprivation based on input-variable domains, the geography over which they are applied, and their output measures. These characteristics can help guide future index selection and application in clinical care, research, and policy decisions.

Association of Economic Well-Being With Comorbid Conditions in Patients Undergoing Carpal Tunnel Release

PURPOSE

Medical comorbidities have been associated with the development of carpal tunnel syndrome (CTS), severity at the time of presentation, and outcomes of carpal tunnel release (CTR). Socioeconomic factors have also been associated with worse function in patients with CTS at presentation and after surgery. However, the effects of economic well-being on the prevalence of medical comorbidities in patients with CTS have not been well-described. The objective of this study was to determine whether economic well-being is associated with medical comorbidities in a cohort of patients undergoing CTR.

METHODS

Patients (n = 1,297) who underwent CTR at a single tertiary care referral center over a 5-year period from July 2008 to June 2013 were retrospectively identified. The exclusion criteria were acute trauma or infection, revision surgery, incomplete medical records, and neoplasm excision. Additionally, patients were excluded if they lacked documented confirmatory or normal electrodiagnostic study findings prior to CTR. Finally, this study comprised a cohort of 892 patients with electrodiagnostic study-confirmed CTS who underwent CTR. The economic well-being of patients was assessed using the Distressed Communities Index. The comorbidities of diabetes mellitus, chronic kidney disease, hypertension, hypothyroidism, cervical radiculopathy, tobacco use, and body mass index were assessed. Bivariate comparisons were used to determine the associations between the tiers of economic well-being and comorbidities.

RESULTS

Lower economic well-being was associated with body mass index, diabetes mellitus, chronic kidney disease, and tobacco use in these patients. Although hypertension, hypothyroidism, and cervical radiculopathy were not associated with economic well-being, their comparisons were underpowered.

CONCLUSIONS

Patients experiencing economic distress have a higher comorbidity burden, and as such, may be at an increased risk of complications or poorer outcomes. The association between economic well-being and comorbidities in this population suggests the need for a multidisciplinary care model that addresses both compressive neuropathy and the associated economic factors.

Systematic Review: Impact of Social Determinants of Health on the Management and Prognosis of Gallstone Disease

Background:

Due to its prevalence, gallstone disease is a major public health issue. It affects diverse patient populations across various socioeconomic levels. Socioeconomic and geographic deprivation may impact both morbidity and mortality associated with digestive diseases, such as biliary tract disease.

Aim:

The aim of this systematic review was to review the available data on the impact of socioeconomic determinants and geographic factors on gallstone disease and its complications.

Methods:

This systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The MEDLINE and Web of Science databases were searched by two investigators to retrieve studies about the impact of income, insurance status, hospital status, education level, living areas, and deprivation indices on gallstone disease. Thirty-seven studies were selected for this review.

Results:

Socially disadvantaged populations appear to be more frequently affected by complicated or severe forms of gallstone disease. The prognosis of biliary tract disease is poor in these populations regardless of patient status, and increased morbidity and mortality were observed for acute cholangitis or subsequent cholecystectomy. Limited or delayed access and low-quality therapeutic interventions could be among the potential causes for this poor prognosis.

Conclusions:

This systematic review suggests that socioeconomic determinants impact the management of gallstone disease. Enhanced knowledge of these parameters could contribute to improved public health policies to manage these diseases.

State-Level Social Vulnerability Index and Healthcare Access: The Behavioral Risk Factor Surveillance System Survey

INTRODUCTION

Access to health care is affected by social determinants of health. The social vulnerability index encompasses multiple social determinants of health simultaneously and may therefore be associated with healthcare access.

METHODS

Cross-sectional data were used from the 2016‒2019 Behavioral Risk Factor Surveillance System, a nationally representative U.S. telephone-based survey of adults aged ≥18 years. State-level social vulnerability index was derived using county-level social vulnerability index estimates from the Centers for Disease Control and Prevention Agency for Toxic Substances and Disease Registry. Analyses were performed in October 2021. Social vulnerability index was ranked according to percentiles, which were divided into tertiles: Tertile 1 (0.10-0.32), Tertile 2 (0.33-0.53), and Tertile 3 (0.54-0.90).

RESULTS

In multivariable-adjusted models comparing U.S. states in Tertile 3 with those in Tertile 1 of social vulnerability index, there was a higher prevalence of absence of healthcare coverage (OR=1.39 [95% CI=1.22, 1.58]), absence of primary care provider (OR=1.34 [95% CI=1.22, 1.48]), >1-year duration since last routine checkup (OR=1.18 [95% CI=1.10, 1.27]), inability to see a doctor because of cost (OR=1.38 [95% CI=1.23, 1.54]), and the composite variable of any difficulty in accessing healthcare (OR=1.15 [95% CI=1.08, 1.22]).

CONCLUSIONS

State-level social vulnerability is associated with several measures related to healthcare access. These results can help to identify targeted interventions to improve access to health care in U.S. states with high social vulnerability index burden.

A Comparison of Area-Level Socioeconomic Status Indices in Colorectal Cancer Care

INTRODUCTION

There are multiple measures of area socioeconomic status (SES) and there is little evidence on the comparative performance of these measures. We hypothesized adding area SES measures improves model ability to predict guideline concordant care and overall survival compared to models with standard clinical and demographic data alone.

MATERIALS AND METHODS

We included patients with colorectal cancer from 2006 to 2015 from the North Carolina Cancer Registry merged with insurance claims data. The primary area SES study variables were the Social Deprivation Index, Distressed Communities Index, Area Deprivation Index, and Social Vulnerability Index. We used multivariable logistic modeling and Cox proportional hazards modeling to assess the adjusted association of each indicator, with guideline concordant care and overall survival, respectively. Model performance of the SES measures was compared to a base model using likelihood ratio testing and area under the curve (AUC) assessments to compare SES indicator models with each other.

RESULTS

We found that the Area Deprivation Index, Social Vulnerability Index and Social Deprivation Index, but not Distressed Communities Index, were significantly associated with receiving guideline concordant care and significantly improved model fit over the base model on likelihood ratio testing. All models had similar AUCs. With respect to overall survival, we found that all indices were independently and significantly associated with survival and had significantly improved model fit over the base model on likelihood ratio testing. AUC analysis again showed all area SES measures had comparable performance for overall survival at 5 y.

CONCLUSIONS

This analysis demonstrates the importance of including these measures in risk adjustment models. However, of the commonly available measures, no one measure stood out as superior to others.

Does Adding a Measure of Social Vulnerability to a Surgical Risk Calculator Improve Its Performance?

BACKGROUND

Emerging literature suggests that measures of social vulnerability should be incorporated into surgical risk calculators. The Social Vulnerability Index (SVI) is a measure designed by the CDC that encompasses 15 socioeconomic and demographic variables at the census tract level. We examined whether adding the SVI into a parsimonious surgical risk calculator would improve model performance.

STUDY DESIGN

The eight-variable Surgical Risk Preoperative Assessment System (SURPAS), developed using the entire American College of Surgeons (ACS) NSQIP database, was applied to local ACS-NSQIP data from 2012 to 2018 to predict 12 postoperative outcomes. Patient addresses were geocoded and used to estimate the SVI, which was then added to the model as a ninth predictor variable. Brier scores and c-indices were compared for the models with and without the SVI.

RESULTS

The analysis included 31,222 patients from five hospitals. Brier scores were identical for eight outcomes and improved by only one to two points in the fourth decimal place for four outcomes with addition of the SVI. Similarly, c-indices were not significantly different (p values ranged from 0.15 to 0.96). Of note, the SVI was associated with most of the eight SURPAS predictor variables, suggesting that SURPAS may already indirectly capture this important risk factor.

CONCLUSION

The eight-variable SURPAS prediction model was not significantly improved by adding the SVI, showing that this parsimonious tool functions well without including a measure of social vulnerability.

The Social Vulnerability Index and Long-term Outcomes after Traumatic Injury

OBJECTIVE

To evaluate the Social Vulnerability Index (SVI) as a predictor of long-term outcomes after injury.

BACKGROUND

The SVI is a measure used in emergency preparedness to identify need for resources in the event of a disaster or hazardous event, ranking each census tract on 15 demographic/social factors.

METHODS

Moderate-severely injured adult patients treated at one of three level-1 trauma centers were prospectively followed six to 14 months post-injury. These data were matched at the census tract level with overall SVI percentile rankings. Patients were stratified based on SVI quartiles, with the lowest quartile designated as low SVI, the middle two quartiles as average SVI, and the highest quartile as high SVI. Multivariable adjusted regression models were used to assess whether SVI was associated with long-term outcomes after injury.

RESULTS

A total of 3,153 patients were included [54% male, mean age 61.6 (SD = 21.6)]. The median overall SVI percentile rank was 35th (IQR: 16th-65th). Compared to low SVI patients, high SVI patients were more likely to have new functional limitations (OR, 1.51; 95% CI, 1.19-1.92), to not have returned to work (OR, 2.01; 95% CI, 1.40-2.89), and to screen positive for PTSD (OR, 1.56; 95% CI, 1.12-2.17). Similar results were obtained when comparing average with low SVI patients, with average SVI patients having significantly worse outcomes.

CONCLUSIONS

The SVI has potential utility in predicting individuals at higher risk for adverse long-term outcomes after injury. This measure may be a useful needs assessment tool for clinicians and researchers in identifying communities that may benefit most from targeted prevention and intervention efforts.

Social Vulnerability And Outcomes For Access-Sensitive Surgical Conditions Among Medicare Beneficiaries

Concerns have been raised over wide variation in rates of unplanned (emergency or urgent) surgery for access-sensitive surgical conditions-diagnoses requiring surgery that preferably is planned (elective) but, when access is limited, may be delayed until worsening symptoms require riskier and costlier unplanned surgery. Yet little is known about geographic and community-level factors that may increase the likelihood of unplanned surgery with adverse outcomes. We examined the relationship between community-level social vulnerability and rates of unplanned surgery for three access-sensitive conditions in 2014-18 among fee-for-service Medicare beneficiaries ages 65-99. Compared with patients from communities with the lowest social vulnerability, those from communities with the highest vulnerability were more likely, overall, to undergo unplanned surgery (36.2 percent versus 33.5 percent). They were also more likely to experience worse outcomes largely attributable to differential rates of unplanned surgery, including higher rates of mortality (5.4 percent versus 5.0 percent) and additional surgery within thirty days (19.6 percent versus 18.1 percent). Our findings suggest that policy addressing community-level social vulnerability may mitigate the observed differences in surgical procedures and outcomes for access-sensitive conditions.

Socioeconomic disadvantage is associated with greater mortality after high-risk emergency general surgery

BACKGROUND

Socioeconomic disadvantage is associated with worse outcomes after elective surgery, but the effect on emergency general surgery (EGS) remains unclear. We examined the association of socioeconomic disadvantage and outcomes after EGS procedures and investigated whether admission to hospitals with comprehensive clinical and social resources mitigated this effect.

METHODS

Adults undergoing 1 of the 10 most burdensome high- and low-risk EGS procedures were identified in six 2014 State Inpatient Databases. Socioeconomic disadvantage was assessed using Area Deprivation Index (ADI) of patient residence. Multivariable logistic regression models adjusting for patient and hospital factors were used to evaluate the association between ADI quartile (high >75 percentile vs. low <25 percentile), and 30-day readmission, in-hospital mortality, and discharge disposition. Effect modification between ADI and (a) level 1 trauma center and (b) safety-net hospital status was tested.

RESULTS

A total of 103,749 patients were analyzed: 72,711 low-risk (70.1%) and 31,038 high-risk procedures (29.9%). Patients from neighborhoods with high socioeconomic disadvantage had a higher proportion with ≥3 comorbidities (41.9% vs. 32.0%), minority race/ethnicity (66.3% vs. 42.4%), and Medicaid (28.8% vs. 14.7%) and were less likely to be treated at level 1 trauma centers (18.3% vs. 27.7%; p < 0.001 for all). Adjusting for competing factors, high socioeconomic disadvantage was associated with increased in-hospital mortality after high-risk procedures (odd ratio, 1.30; 95% confidence interval, 1.01-1.66; p = 0.04) and higher odds of non-home discharge (odd ratio, 1.15; 95% confidence interval, 1.02-1.30; p = 0.03) for low-risk procedures. Socioeconomic disadvantage was not associated with 30-day readmission for either procedure group. Level 1 trauma status and safety-net hospital did not meaningfully mitigate effect of ADI for any outcome.

CONCLUSION

Socioeconomic disadvantage is associated with increased mortality after high-risk procedures and higher odds of non-home discharge after low-risk procedures. This effect was not mitigated by either level 1 trauma or safety-net hospitals. Interventions that specifically address the needs of socially vulnerable communities will be required to significantly improve EGS outcomes for this population.

Area Deprivation and Medicare Spending for Coronary Artery Bypass Grafting: Insights from Michigan

BACKGROUND

Prior work has established that high socioeconomic deprivation is associated with worse short- and long-term outcomes for coronary artery bypass graft (CABG) patients. The relationship between socioeconomic status and 90-day episode spending is poorly understood. In this observational cohort analysis, we evaluated whether socioeconomically disadvantaged patients were associated with higher expenditures during 90-day episodes of care following isolated CABG.

METHODS

We linked clinical registry data from 8,728 isolated CABG procedures from January 1st, 2012 to December 31st, 2018 to Medicare fee-for-service claims data. Our primary exposure variable was patients in the top decile of the Area Deprivation Index. Linear regression was used to compare risk-adjusted, price-standardized 90-day episode spending for deprived against non-deprived patients, as well as component spending categories: index hospitalization, professional services, post-acute care, and readmissions.

RESULTS

A total of 872 patients were categorized as being in the top decile. Mean 90-day episode spending for the 8,728 patients in the sample was $55,258 (standard deviation = $26,252). Socioeconomically deprived patients had higher overall 90-day spending compared to non-deprived patients ($61,579 vs. $54,557, difference = $3,003, p = 0.001). Spending was higher in socioeconomically deprived patients for index hospitalizations (difference = $1,284, p = 0.005), professional services (difference = $379, p = 0.002) and readmissions (difference = $1,188, p = 0.008). Inpatient rehabilitation was the only significant difference in post-acute care spending (difference = $469, p = 0.011).

CONCLUSIONS

Medicare spending was higher for socioeconomically deprived CABG in Michigan, indicating systemic disparities over and above patient demographic factors.

The clinical effect and safety of new preoperative fasting time guidelines for elective surgery: a systematic review and meta-analysis

BACKGROUND

Traditional fasting and no drinking schemes (fasting for 8-12 hours and no drinking for 4-6 hours) affect the metabolism of the body. The new guidelines put forward by the American Association of Anesthesiologists (fasting for 6 hours, no drinking for 2 hours) obviously reduce the time of fasting and no drinking, but the clinical efficacy and safety need to be further confirmed. In this study, a meta-analysis of randomized controlled trials (RCTs) using the new guidelines and traditional protocols was conducted to provide an evidence-based foundation for elective surgery.

METHODS

The articles were searched in PubMed, EBSCO, MEDLINE, Science Direct, Cochrane Library, CNKI, China Biomedical Resources Database, Wanfang Database, Weipu, and Western Biomedical Journal Literature Database. RCTs related to fasting before surgery during the screening period were selected. Chinese and English search keywords included elective surgery, preoperative, fasting and no drinking, patient comfort, thirst, hunger, collapse, hypoglycemia, preoperative gastric volume, preoperative gastric juice pH, and intraoperative gastric volume. The RevMan 5.3 software provided by Cochrane collaboration network was used to evaluate the quality of included documents. Two professionals independently screened the literature, extracted data, and assessed the risk of bias.

RESULTS

A total of 6 studies were included. The incidence of hunger in patients undergoing elective surgery in the experimental group and control group was significantly different [Z=3.90; relative risk (RR) =0.58; 95% confidence interval (CI): 0.44, 0.76; P<0.0001]. The incidence of thirst was significantly different between the experimental group and control group (Z=7.22; RR =0.21; 95% CI: 0.13, 0.32; P<0.00001).

DISCUSSION

Meta-analysis results confirmed that the new guidelines can significantly reduce the hunger and thirst of patients, improve their satisfaction after surgery, and can be applied clinically.

Association of Postoperative Undertriage to Hospital Wards With Mortality and Morbidity

IMPORTANCE

Undertriaging patients who are at increased risk for postoperative complications after surgical procedures to low-acuity hospital wards (ie, floors) rather than highly vigilant intensive care units (ICUs) may be associated with risk of unrecognized decompensation and worse patient outcomes, but evidence for these associations is lacking.

OBJECTIVE

To test the hypothesis that postoperative undertriage is associated with increased mortality and morbidity compared with risk-matched ICU admission.

DESIGN, SETTING, AND PARTICIPANTS

This longitudinal cross-sectional study was conducted using data from the University of Florida Integrated Data Repository on admissions to a university hospital. Included patients were individuals aged 18 years or older who were admitted after a surgical procedure from June 1, 2014, to August 20, 2020. Data were analyzed from April through August 2021.

EXPOSURES

Ward admissions were considered undertriaged if their estimated risk for hospital mortality or prolonged ICU stay (ie, ≥48 hours) was in the top quartile among all inpatient surgical procedures according to a validated machine-learning model using preoperative and intraoperative electronic health record features available at surgical procedure end time. A nearest neighbors algorithm was used to identify a risk-matched control group of ICU admissions.

MAIN OUTCOMES AND MEASURES

The primary outcomes of hospital mortality and morbidity were compared among appropriately triaged ward admissions, undertriaged wards admissions, and a risk-matched control group of ICU admissions.

RESULTS

Among 12 348 postoperative ward admissions, 11 042 admissions (89.4%) were appropriately triaged (5927 [53.7%] women; median [IQR] age, 59 [44-70] years) and 1306 admissions (10.6%) were undertriaged and matched with a control group of 2452 ICU admissions. The undertriaged group, compared with the control group, had increased median [IQR] age (64 [54-74] years vs 62 [50-73] years; P = .001) and increased proportions of women (649 [49.7%] women vs 1080 [44.0%] women; P < .001) and admitted patients with do not resuscitate orders before first surgical procedure (53 admissions [4.1%] vs 27 admissions [1.1%]); P < .001); 207 admissions that were undertriaged (15.8%) had subsequent ICU admission. In the validation cohort, hospital mortality and prolonged ICU stay estimations had areas under the receiver operating characteristic curve of 0.92 (95% CI, 0.91-0.93) and 0.92 (95% CI, 0.92-0.92), respectively. The undertriaged group, compared with the control group, had similar incidence of prolonged mechanical ventilation (32 admissions [2.5%] vs 53 admissions [2.2%]; P = .60), decreased median (IQR) total costs for admission ($26 900 [$18 400-$42 300] vs $32 700 [$22 700-$48 500]; P < .001), increased median (IQR) hospital length of stay (8.1 [5.1-13.6] days vs 6.0 [3.3-9.3] days, P < .001), and increased incidence of hospital mortality (19 admissions [1.5%] vs 17 admissions [0.7%]; P = .04), discharge to hospice (23 admissions [1.8%] vs 14 admissions [0.6%]; P < .001), unplanned intubation (45 admissions [3.4%] vs 49 admissions [2.0%]; P = .01), and acute kidney injury (341 admissions [26.1%] vs 477 admissions [19.5%]; P < .001).

CONCLUSIONS AND RELEVANCE

This study found that admitted patients at increased risk for postoperative complications who were undertriaged to hospital wards had increased mortality and morbidity compared with a risk-matched control group of admissions to ICUs. Postoperative undertriage was identifiable using automated preoperative and intraoperative data as features in real-time machine-learning models.
