Health care disparity exists among those undergoing emergent hernia repairs in New York State

Association of socioeconomic vulnerability with clinical and financial outcomes following emergent hernia repair

BACKGROUND

While race and insurance have been linked with greater likelihood of hernia incarceration and emergent presentation, the association of broader social determinants of health (SDOH) with outcomes following urgent repair remains to be elucidated.

STUDY DESIGN

All adult hospitalizations entailing emergent repair for strangulated inguinal, femoral, and ventral hernias were identified in the 2016-2020 Nationwide Readmissions Database. Socioeconomic vulnerability was ascertained using relevant diagnosis codes. Multivariable models were developed to consider the independent associations between socioeconomic vulnerability and study outcomes.

RESULTS

Of ∼236,215 patients, 20,306 (8.6 ​%) were Vulnerable. Following risk-adjustment, socioeconomic vulnerability remained associated with greater odds of in-hospital mortality, any perioperative complication, increased hospitalization expenditures and higher risk of non-elective readmission.

CONCLUSIONS

Among patients undergoing emergent hernia repair, socioeconomic vulnerability was linked with greater morbidity, expenditures, and readmission. As part of patient-centered care, novel screening, postoperative management, and SDOH-informed discharge planning programs are needed to mitigate disparities in outcomes.

Determining the Association Between Insurance Type and Myofascial Release in Large Ventral Hernias

INTRODUCTION

Abdominal wall reconstruction (AWR) utilizes advanced myofascial releases to perform complex ventral hernia repair (VHR). The relationship between the performance of AWR and disparities in insurance type is unknown.

METHODS

The Abdominal Core Health Quality Collaborative was queried for adults who had undergone an elective VHR between 2013 and 2020 with a hernia size ≥10 cm. Patients with missing insurance data were excluded. Comparison groups were divided by insurance type: favorable (private, Medicare, Veteran's Administration, Tricare) or unfavorable (Medicaid and self-pay). Propensity score matching compared the cumulative incidence of AWR between the favorable and unfavorable insurance comparison groups.

RESULTS

In total, 26,447 subjects met inclusion criteria. The majority (89%, n = 23,617) had favorable insurance, while (11%, n = 2830) had unfavorable insurance. After propensity score matching, 2821 patients with unfavorable insurance were matched to 7875 patients with favorable insurance. The rate of AWR with external oblique release or transversus abdominis release was significantly higher (23%, n = 655) among the unfavorable insurance group compared to those with favorable insurance (21%, n = 1651; P = 0.013).

CONCLUSIONS

This study provides evidence that patients with unfavorable insurance may undergo AWR with external oblique or transversus abdominis release at a greater rate than similar patients with favorable insurance. Understanding the mechanisms contributing to this difference and evaluating the financial implications of these trends represent important directions for future research in elective VHR.

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.

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.

Prediction models in hernia repair: a systematic review

BACKGROUND

Hernias can present with unique challenges when it comes to management and repair. Prediction models can be a useful tool for clinicians to better anticipate and understand the severity of a hernia, the type of surgical technique, or presurgical planning that may be required to treat the patient, and the risk of complications. Our goal is to evaluate and consolidate prediction models in hernia repair present in the literature for which physicians can reference to best improve patient outcomes and postoperative management.

METHODS

We performed a literature search in PubMed using keywords, "rectus width to defect width ratio," "predicting myofascial release," "computed tomography hernia repair prediction," "component separation radiology prediction hernia," "fat volume and hernia repair," "body morphometrics and Query hernia repair," "body morphometrics and reherniation," "computed tomography findings and risk of emergency hernia repair," "loss of domain and hernia radiology," and "volumetry and hernia repair." We searched for publications that used radiographic parameters to predict hernia severity, interventions, and outcomes.

RESULTS

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), we found twenty-three studies related to prediction models in hernia repair published between 2000 and 2021. We summarized studies pertaining to predicting acute care, predicting operative planning with loss of domain and component separation, predicting complications, paraesophageal hernia predictions, and predicting postoperative respiratory complications.

CONCLUSION

Radiographic prediction models can be an objective and efficient way for surgeons to analyze hernias and better understand a patient's situation so that they can inform patients about the best treatment options and the risk of complications.

Socioeconomic disparities in the utilization of primary robotic hernia repair

OBJECTIVE

This study aimed to examine socioeconomic disparities in the utilization of primary robotic hernia repair (RHR), utilizing statewide population-level data. It was funded by the SAGES Robotic Surgery Research Grant.

METHODS AND PROCEDURES

The New York Statewide Planning and Research Cooperative System (SPARCS) administrative database was used to identify adult patients who underwent primary open, laparoscopic, and robotic hernia repair (inguinal, femoral, umbilical, ventral) from 2010 through 2016. Utilization trends were compared between the surgical approaches, assessing for difference in age, sex, race, insurance status, and socioeconomic status (as defined by median income for zip code). Multivariable regression models were used with statistical significance set at 0.05.

RESULTS

A total of 280,064 patients underwent primary hernia repair: n = 216,892 (77.4%) open, n = 61,037 (21.8%) laparoscopic, and n = 2,135 (0.8%) robotic. After adjusting for confounding variables, senior age (OR 1.01, p = 0.002), male sex (OR 1.35, p < 0.001), and non-Hispanic race (OR 1.3-1.54, p < 0.001) were significantly associated with the use of robotic compared to open or laparoscopic surgery. Additionally, patients with commercial insurance were more likely to undergo RHR compared to those with Medicare (OR 1.32) or Medicaid (OR 1.54) (p < 0.0001). Income was significantly correlated with RHR such that every $10,000 increase in income would increase the odds of having RHR by 6% (OR 1.06, p < 0.0001). Academic facilities were also associated with a significantly higher likelihood of utilizing RHR (OR 1.88, p < 0.0001).

CONCLUSION

There are significant socioeconomic disparities in the utilization of robotic compared to laparoscopic or open hernia repair. While the robotic approach is overall increasing in popularity, adoption of new technology should not be limited to specific socioeconomic cohorts of the population. Recognizing these disparities is a necessary first step in providing equal and consistent care.

The Abdominal Hernia-Q: a critical analysis of the components that impact quality-of-life

PURPOSE

Ventral hernias (VH) are a common surgical problem associated with significant morbidity. While assessment tools have examined quality-of-life (QoL), the relative change in specific domains of hernia-related QoL measures from pre- to post-operative period has yet to be comprehensively examined. Using the Abdominal Hernia-Q (AHQ), this study aims to assess the impact of ventral hernia repair (VHR) on key components of QoL.

METHODS

A retrospective chart review was conducted of patients undergoing VHR between September 2017 and September 2019 who had completed at least one pre- and post-operative AHQ. Post-operative intervals were created to capture AHQ responses around standard follow-up visits (< 1.5 months, 1.5-4.5 months, 4.5-11 months, and 11 + months) and scores were statistically analyzed.

RESULTS

A total of 136 patients were included, with an average age of 54.8 years at the time of VHR. Compared to the pre-operative period, the appearance score increased significantly (p < 0.05). The physical domain score increased from < 1.5 month to the 1.5-4.5 month period (p = 0.03) and remained significantly higher in later time period. The appearance score decreased from the 1.5-4.5 month to 4.5-11 month period (p = 0.05).

CONCLUSIONS

VHR leads to a sustained multi-dimensional increase in hernia-specific QoL measures during the post-operative course driven by early positive changes in appearance and sustained physical functioning. The initial increase in QoL is mainly driven by an improvement in appearance, while the sustained increase may be due to restored physical function.

Academic and community hernia center websites in the United States fail to meet healthcare literacy standards of readability

BACKGROUND

Health literacy is considered the single best predictor of health status. Organizations including the American Medical Association (AMA) and the National Institutes of Health (NIH) have recommended that the readability of patient education materials not exceed the sixth-grade level. Our study focuses on the readability of self-designated hernia centers websites at both academic and community organizations across the United States to determine their ability to dispense patient information at an appropriate reading level.

METHODS

A search was conducted utilizing the Google search engine. The key words "Hernia Center" and "University Hernia Center" were used to identify links to surgical programs within the United States. The following readability tests were conducted via the program: Flesch-Kincaid Grade Level (FKGL), Gunning Fox Index (GFI), Coleman-Liau Index (CLI), Simple Measure of Gobbledygook (SMOG), and Flesch Reading Ease (FRE) score.

RESULTS

Of 96 websites, zero (0%) had fulfilled the recommended reading level in all four tests. The mean test scores for all non-academic centers (n = 50) were as follows: FKGL (11.14 ± 2.68), GFI (14.39 ± 3.07), CLI (9.29 ± 2.48) and SMOG (13.38 ± 2.03). The mean test scores [SK1] for all academic programs (n = 46) were as follows: FKGL (11.7 ± 2.66), GFI (15.01 ± 2.99), CLI (9.34 ± 1.91) and SMOG (13.71 ± 2.02). A one-sample t test was performed to compare the FKGL, GFI, CLI, and SMOG scores for each hernia center to a value of 6.9 (6.9 or less is considered an acceptable reading level) and a p value of 0.001 for all four tests were noted demonstrating statistical significance. The Academic and Community readability scores for both groups were compared to each other with a two-sample t test with a p value of > 0.05 for all four tests and there were no statistically significant differences.

CONCLUSION

Neither Academic nor Community hernia centers met the appropriate reading level of sixth-grade or less. Steps moving forward to improve patient comprehension and/or involving with their care should include appropriate reading level material, identification of a patient with a low literacy level with intervention or additional counseling when appropriate, and the addition of adjunct learning materials such as videos.

The Impact of the COVID-19 Pandemic on Sociodemographic Disparities in Rates of Elective Hernia Surgeries

BACKGROUND

The global pandemic has shed light on the role of health care disparities; however, little data exists to determine how COVID-19 affected access to elective surgical care. We aimed to determine the impact of health care disparities and surgical care for patients undergoing hernia surgery across a national quality collaborative database.

MATERIALS AND METHODS

All patients undergoing elective hernia surgery between March 2018 and April 2021 were identified within the Abdominal Core Health Quality Collaborative. Patients were divided based on date of surgery into pre-, post-, and COVID-19 spike groups. Descriptive statistics were calculated for comorbidities, demographics, surgical location, Distressed Community Index (DCI), and hernia characteristics stratified by period of surgery. Rates and chi-squared test were used for categorical variables. Median, IQR, and Wilcoxon test were used continuous variables.

RESULTS

35 149 patients met inclusion criteria. Pre-COVID-19, COVID-19 spike, and post-COVID-19 groups showed no significant difference in mean age or the proportion of patients in each DCI variable. Proportionately fewer females and more White non-Hispanic patients were operated on during the COVID-19 spike. Surgeons affiliated with academic hospitals saw proportionality fewer elective cases during the COVID-19 spike.

DISCUSSION

This study suggests white males with private hospital affiliation were more likely to have elective hernia surgery during the COVID-19 spike, however these trends were not associated with health care DCI changes during the same period. Further study is necessary to determine the reasons for these differences and will be important to optimize surgical care for patients during a worldwide pandemic.
