Socioeconomic factors and parity of access to robotic surgery in a county health system

Robotic availability, not payor status, determines access to robotic emergency general surgery hernia repair in California and Florida

BACKGROUND

Previous studies have demonstrated that access to robotic surgery is influenced by socioeconomic factors, including insurance status. The 2010 Affordable Care Act established an avenue for states to expand Medicaid coverage, which has increased access to surgical care for many conditions. We hypothesized that socioeconomic disparities in access to robotic repair of non-elective emergency general surgery (EGS) hernias are less prevalent in California, a Medicaid expansion state, compared to Florida, which has not adopted Medicaid expansion.

METHODS

The 2021 California and Florida State Inpatient Databases were used to identify all EGS admissions with an ICD-10 procedure code for ventral or inguinal hernia repair. Elective procedures and those with concurrent unrelated abdominal procedures were excluded. Patient demographics, comorbidity burden, payor status, and income quartile were abstracted. Aggregation of hospital data identified high-volume trauma, robotic, and EGS centers.

RESULTS

There were 15,683 EGS hernia procedures of which 11% underwent robotic repair: 14% in Florida and 8% in California. On multivariable logistic regression, older age, male sex, lower income, and Medicare insurance were associated with reduced odds of robotic hernia repair in California, but not in Florida, despite an uninsured rate of 10%. The greatest predictor of robotic surgery in both states was treatment at a robotic surgery center. Overall, accounting for patient- and hospital-level factors, hernia surgeries in Florida were more likely to involve robotics (OR 1.61, CI 1.42-1.81, p < 0.001) compared to California.

CONCLUSION

There were fewer disparities in access to EGS robotic hernia repairs in Florida than in California. This suggests that robotic surgery access for EGS hernia repairs is primarily determined by institutional adoption of robotic surgery, not income or payor status. Compared to California, Florida appears to have greater market penetration of robotic surgery, which has increased access to robotic EGS for all patients.

The impact of distance to facility on treatment modality, short-term outcomes, and survival of patients with HPV-positive oropharyngeal squamous cell carcinoma

PURPOSE

This study compared treatment and outcomes for patients with HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) based on their travel distance to treatment facility.

MATERIALS AND METHODS

Patients with cT1-4, N0-3, M0 HPV-positive OPSCC in the National Cancer Database from 2010 to 2019 were identified and split into four quartiles based on distance to facility, with quartile 4 representing patients with furthest travel distances. Multivariable-adjusted logistic regression and Cox proportional hazards modeling were used to analyze the primary outcome of treatment received, and secondary outcomes of clinical stage, overall survival, surgical approach (i.e., TORS versus other), and 30-day surgical readmissions.

RESULTS

17,207 patients with HPV-positive OPSCC were evenly distributed into four quartiles. Compared to patients in quartile 1, patients in quartile 4 were 40 % less likely to receive radiation versus surgery (OR = 0.60; 95 % CI = 0.54-0.66). Among the patients who received surgery, quartile 4 had a higher odds of receiving TORS treatment compared to quartile 1 (4v1: OR = 2.38; 95 % CI = 2.05-2.77), quartile 2 (4v2: OR = 2.31, 95 % CI = 2.00-2.66), and quartile 3 (4v3: OR = 1.75; 95 % CI = 1.54-1.99). Quartile 4 had a decreased odds of mortality compared to Quartile 1 (4v1: OR = 0.87; 95 % CI = 0.79-0.97). There were no differences among the quartiles in presenting stage and 30-day readmissions.

CONCLUSIONS

This study found that patients with furthest travel distance to facility were more often treated surgically over non-surgical management, with TORS over open surgery, and had better overall survival. These findings highlight potential disparities in access to care for patients with HPV-positive OPSCC.

Racial and Socioeconomic Disparities in Complex Abdominal Wall Reconstruction Referrals

Background: Health disparities are pervasive in surgical care. Particularly racial and socioeconomic inequalities have been demonstrated in emergency general surgery outcomes, but less so in elective abdominal wall reconstruction (AWR). The goal of this study was to evaluate the disparities in referrals to a tertiary hernia center. Methods: A prospectively maintained hernia database was queried for patients who underwent open ventral hernia (OVHR) or minimally invasive surgical (MISR) repair from 2011 to 2022 with complete insurance and address information. Patients were divided by home address into in-state (IS) and out-of-state (OOS) referrals as well as by operative technique. Demographic data and outcomes were compared. Standard and inferential statistical analyses were performed. Results: Of 554 patients, most were IS (59.0%); 334 underwent OVHR, and 220 underwent MISR. IS patients were more likely to undergo MISR (OVHR: 45.6% vs. 81.5%, laparoscopic: 38.2% vs. 14.1%, robotic: 16.2% vs. 4.4%; p < 0.001) when compared to OOS referrals. Of OVHR patients, 44.6% were IS and 55.4% were OOS. Patients' average age and BMI, sex, ASA score, and insurance payer were similar between IS and OOS groups. IS patients were more often Black (White: 77.9% vs. 93.5%, Black: 16.8% vs. 4.3%; p < 0.001). IS patients had more smokers (12.1% vs. 3.2%; p = 0.001), fewer recurrent hernias (45.0% vs. 69.7%; p < 0.001), and smaller defects (155.7 ± 142.2 vs. 256.4 ± 202.9 cm2; p < 0.001). Wound class, mesh type, and rate of fascial closure were similar, but IS patients underwent fewer panniculectomies (13.4% vs. 34.1%; p < 0.001), component separations (26.2% vs. 51.4%; p < 0.001), received smaller mesh (744.2 ± 495.6 vs. 975.7 ± 442.3 cm2; p < 0.001), and had shorter length-of-stay (4.8 ± 2.0 vs. 7.0 ± 5.5 days; p < 0.001). There was no difference in wound breakdown, seroma requiring intervention, hematoma, mesh infection, or recurrence; however, IS patients had decreased wound infections (2.0% vs. 8.6%; p = 0.009), overall wound complications (11.4% vs. 21.1%; p = 0.016), readmissions (2.7% vs. 13.0%; p = 0.001), and reoperations (3.4% vs. 11.4%; p = 0.007). Of MISR patients, 80.9% were IS and 19.1% were OOS. In contrast to OVHR, MISR IS and OOS patients had similar demographics, preoperative characteristics, intraoperative details, and postoperative outcomes. Conclusion: Although there were no differences in referred patients for MISR, this study demonstrates the racial disparities that exist among our IS and OOS complex, open AWR patients. Awareness of these disparities can help clinicians work towards equitable access to care and equal referrals to tertiary hernia centers.

Disparities in access to robotic technology and perioperative outcomes among patients treated with radical prostatectomy

BACKGROUND

Most radical prostatectomies are completed with robotic assistance. While studies have previously evaluated perioperative outcomes of robot-assisted radical prostatectomy (RARP), this study investigates disparities in access and clinical outcomes of RARP.

STUDY DESIGN

The National Cancer Database (NCDB) was used to identify patients who received radical prostatectomy for cancer between 2010 and 2017 with outcomes through 2018. RARP was compared to open radical prostatectomy (ORP). Odds of receiving RARP were evaluated while adjusting for covariates. Overall survival was evaluated using a propensity-score matched cohort.

RESULTS

Overall, 354 752 patients were included with 297 676 (83.9%) receiving RARP. Patients who were non-Hispanic Black (82.8%) or Hispanic (81.3%) had lower rates of RARP than non-Hispanic White (84.0%) or Asian patients (87.7%, p < 0.001). Medicaid or uninsured patients were less likely to receive RARP (75.5%) compared to patients with Medicare or private insurance (84.4%, p < 0.001). Medicaid or uninsured status was associated with decreased odds of RARP in adjusted multivariable analysis (OR 0.61, 95% CI 0.49-0.76). RARP was associated with decreased perioperative mortality and improved overall survival compared to ORP.

CONCLUSION

Patients who were underinsured were less likely to receive RARP. Improved access to RARP may lead to decreased disparities in perioperative outcomes for prostate cancer.

Assessing the impact of socio-economic determinants on access to care, surgical treatment options and outcomes among patients with renal mass: Insight from the universal healthcare system

OBJECTIVE

To assess whether socio-economic disparities exist on access to care, treatment options and outcomes among patients with renal mass amenable of surgical treatment within the universal healthcare system.

METHODS

Data of consecutive patients submitted to partial nephrectomy (PN) or radical nephrectomy (RN) at our Institution between 2017 and 2020 were retrospectively evaluated. Patients were grouped according to their income level (low, intermediate, and high) based on the Indicator of Equivalent Economic Situation national criterion. Survival analysis was performed. Cox regression models were employed to analyse the impact of socio-economic variables on survival outcomes.

RESULTS

One thousand forty-two patients were included (841 PN and 201 RN). Patients at the lowest income level were found more likely symptomatic and with a higher pathological tumour stage in the RN cohort (p > 0.05). The guidelines adherence on surgical indication rate as well as the access to minimally invasive surgery did not differ according to patient's income level in both cohorts (p > 0.05). Survival curves were comparable among the groups. Cox regression analysis showed that none of the included socio-economic variables was associated with survival outcomes in our series.

CONCLUSIONS

Universal healthcare system may increase the possibility to ensure egalitarian treatment modalities for patients with renal cancer.

Random forest modeling using socioeconomic distress predicts hernia repair approach

BACKGROUND

Surgical techniques for abdominal wall hernia repair have advanced, yet it is unclear if all patient populations experience these innovations equally. We hypothesized that in patients undergoing abdominal wall herniorrhaphy, there would be socioeconomic variation between robotic, laparoscopic, and open approaches.

METHODS

We performed a retrospective review of patients undergoing abdominal wall herniorrhaphy at a tertiary care center from 2013 through 2019. Patients were stratified by approach: laparoscopic (LH), open (OH), or robotic (RH). Insurance type was categorized as private, Medicare, or Medicaid/uninsured. Using zip code data, we obtained a Distressed Communities Index (DCI), which is comprised of 7 unique socioeconomic variables. We employed random forest (RF) modeling to predict surgical approach and determined each factor's variable importance (VI) for our model.

RESULTS

There were 559 patients; 39.7% (n = 222) LH, 33.3% (n = 186) OH, and 27% (n = 151) RH. The DCI (p < 0.01) and rates of poverty (p = 0.01), adults without diplomas (p < 0.01), and unemployment (p < 0.01) were highest in the OH group while job growth (p = 0.02) and median income ratio (p < .01) were highest in the RH group. The LH group had a greater proportion of privately insured patients than Medicaid/ uninsured patients (43.4% vs 15.9%, p < 0.01). The most important variables identified by our RF model were job growth (for RH), insurance type (for LH), and no high school diploma (for OH).

CONCLUSION

Insurance type, job growth, and educational attainment may influence operative approach and can contribute to the existing disparities in hernia surgery. Surgeons should address these inequalities and commit to parity in the delivery of surgical care.
