Racial disparities after stoma construction in colorectal surgery

Disparities in the Delivery of Prostate Cancer Survivorship Care in the USA: A Claims-based Analysis of Urinary Adverse Events and Erectile Dysfunction Among Prostate Cancer Survivors

Background and objective

Incidence rates for prostate cancer (PCa) diagnosis and mortality are higher for Black men. It is unknown whether similar disparities exist in survivorship care. We assessed the delivery and quality of survivorship care for Black men undergoing PCa therapy in terms of the burden of and treatment for urinary adverse events (UAEs) and erectile dysfunction (ED).

Methods

We queried Optum Clinformatics data for all patients diagnosed with PCa from January 1, 2002 to December 31, 2017 and identified those who underwent primary PCa treatment. Index cohorts were identified in each year and followed longitudinally until 2017. Data for UAE diagnoses, UAE treatments, and ED treatments were analyzed in index cohorts. Cox proportional-hazards regression models were used to examine associations of race with UAE diagnosis, UAE treatment, and ED treatment.

Key findings and limitations

We identified 146, 216 patients with a PCa diagnosis during the study period, of whom 55, 149 underwent primary PCa treatment. In the primary treatment group, 32.7% developed a UAE and 28.2% underwent UAE treatment. The most common UAEs were urinary incontinence (11%), ureteral obstruction/stricture (4.5%), bladder neck contracture (4.5%), and urethral stricture (3.7%). The most common UAE treatments were cystoscopy (13%), suprapubic tube placement (6%), and urethral dilation (5%). Overall, UAE diagnosis rates were higher for Black patients, who had significantly higher risk of urethral obstruction, rectourethral fistula, urinary incontinence, cystitis, urinary obstruction, and ureteral fistula. Overall, UAE treatment rates were lower for Black patients, who had significantly higher risk of fecal diversion and/or rectourethral fistula repair (adjusted hazard ratio [aHR] 1.71, 95% confidence interval [CI] 1.04-2.79). Regarding ED treatments, Black patients had higher risk of penile prosthesis placement (aHR 1.591, 95% CI 1.26-2.00) and intracavernosal injection (aHR 1.215, 95% CI 1.08-1.37).

Conclusions and clinical implications

Despite a high UAE burden, treatment rates were low in a cohort with health insurance. Black patients had a higher UAE burden and lower UAE treatment rates. Multilevel interventions are needed to address this stark disparity. ED treatment rates were higher for Black patients.

Patient summary

We reviewed data for patients treated for prostate cancer (PCa) and found that 32.7% were diagnosed with a urinary adverse event (UAE) following their PCa treatment. The overall treatment rate for these UAEs was 28.2%. Analysis by race showed that the UAE diagnosis rate was higher for Black patients, who were also more likely to receive treatment for erectile dysfunction.

Maximizing Readmission Reduction in Colon Cancer Patients

INTRODUCTION

Multiple studies have identified risk factors for readmission in colon cancer patients. We need to determine which risk factors, when modified, produce the greatest decrease in readmission for patients so that limited resources can be used most effectively by implementing targeted evidence-based performance improvements. We determined the potential impact of various modifiable risk factors on reducing 30-d readmission in colon cancer patients.

METHODS

We used a cohort design with the 2012-2020 American College of Surgeons' National Surgical Quality Improvement Program data to track colon cancer patients for 30 d following surgery. Colon cancer patients who received colectomies and were discharged alive were included. Readmission (to the same or another hospital) for any reason within 30 d of the resection was the outcome measure. Modifiable risk factors were the use of minimally invasive surgery (MIS) versus open colectomy, mechanical bowel preparation, preoperative antibiotic use, functional status, smoking, complications (deep vein thrombosis, pulmonary embolism, myocardial infarction, stroke, infections, anastomotic leakage, prolonged postoperative ileus, extensive blood loss, and sepsis), serum albumin, and hematocrit.

RESULTS

111,691 patients with colon cancer were included in the analysis. About half of the patients were male, most were aged 75 or older, and were discharged home. Overall, 11,138 patients (10.0%) were readmitted within 30 d of surgery. In adjusted analysis, the reduction in readmission would be largest by preventing both prolonged ileus and by switching open colectomies to MIS (28.0% relative reduction) followed by preventing anastomotic leaks (6.2% relative reduction). Improving other modifiable risk factors would have a more limited impact.

CONCLUSIONS

The focus of readmission reduction should be on preventing prolonged ileus, increasing the use of MIS, and preventing anastomotic leaks.

A National Inpatient Sample Analysis of Racial Disparities After Segmental Colectomy for Inflammatory Colorectal Diseases

BACKGROUND

Racial disparities and poor access to care are common among African Americans (AA), potentially adversely affecting surgical outcomes in inflammatory bowel conditions. We aimed to analyze the effect of race on outcomes in patients undergoing segmental colectomy for inflammatory bowel conditions.

METHODS

Retrospective review of data from the National Inpatient Sample between 2010 and 2015 identified patients who underwent segmental colectomy without ostomy for Crohn's or diverticular disease. AA patients were compared with Caucasians using a multivariable analysis model. Primary outcomes of interest were overall complications, mortality, and extended hospital stay.

RESULTS

38,143 admissions were analyzed; AA patients constituted 8% of the overall cohort. Diagnoses included Crohn's (11%) and diverticular disease (89%). After multivariable analysis, AA patients had significantly higher overall risk of complications (OR = 1.27; 95% CI, 1.15-1.40) and extended hospital stay (OR = 1.59; 95% CI, 1.45-1.75) than Caucasians. On bivariate analysis, there was no significant difference in mortality between AA and Caucasian patients. AA patients had significantly higher rates of Medicaid insurance (14% vs 6%, P < .001), lower rates of private insurance (35% vs 47%, P < .001), and were less likely to undergo surgery at a private hospital (31% vs 41%, P < .001).

CONCLUSIONS

AA patients requiring segmental colectomy for inflammatory colorectal conditions experience significantly higher rates of postoperative complications, longer hospital stays, and lower rates of private insurance. Direct correlation between insurance status and postoperative outcomes could not be established, but we speculate such great disparity in outcomes may stem from these socioeconomic differences.

Racial disparities in postoperative outcomes persist for patients with inflammatory bowel disease under a colorectal enhanced recovery program

INTRODUCTION

Enhanced recovery programs (ERPs) reduce racial disparities in surgical outcomes for general colorectal surgery populations. It is unclear, however, if disparities in IBD populations are impacted by ERPs.

METHODS

Retrospective study comparing IBD patients undergoing major elective colorectal operations before (2006-2014) and after (2015-2021) ERP implementation using ACS-NSQIP data. The primary outcome of length of stay (LOS) was analyzed by negative binomial regression, and secondary outcomes (complications and readmissions) by logistic regression.

RESULTS

Of 466 IBD patients, 47% were pre-ERP and 53% were ERP patients. In multivariable analysis stratified by ERP period, Black race was associated with increased odds of complications in the pre-ERP (OR 3.6, 95%CI 1.4-9.3) and ERP groups (OR 3.1 95%CI 1.3-7.6). Race was not a predictor of LOS or readmission in either group. High social vulnerability was associated with increased odds of readmission pre-ERP (OR 15.1, 95%CI 2.1-136.3), but this disparity was mitigated under ERPs (OR 1.4, 95%CI 0.4-5.6).

CONCLUSION

While ERPs mitigated some disparities by social vulnerability, racial disparities persist in IBD populations even under ERPs. Further work is needed to achieve surgical equity for IBD patients.

Factors Affecting Psychosocial Adjustment in Persons With a Recent Ostomy

PURPOSE

The aim of this study was to examine the influence of personal and clinical factors on psychosocial adjustment in persons living with an ostomy for less than 1 year.

DESIGN

A cross-sectional survey.

SUBJECTS AND SETTING

The study sample comprised 183 adult individuals who had a colostomy, ileostomy, or urostomy for less than 1 year, residing in the Northeastern United States.

METHODS

Data were collected from May through November 2018 using 2 instruments: a sociodemographic questionnaire and the Ostomy Adjustment Inventory-23 (OAI-23). The OAI-23 items measured 4 psychosocial subscales: acceptance, anxious preoccupation, social engagement, and anger. Data were analyzed using analysis of variance, multivariate analysis of variance, Cramer's V correlations, and multiple regression.

RESULTS

Univariate analysis indicated that factors influencing psychosocial adjustment to an ostomy include age, assistance with care, educational background, stomal type, body mass index, ostomy height, preoperative education, and stoma siting. Multivariate analysis of variance identified that those who reported independence with ostomy care experienced higher levels of adjustment in all areas of the OAI-23.

CONCLUSIONS

Findings from this study may assist nurses and other care providers to better understand the physical and emotional needs of those with ostomies and to identify interventions to promote optimal health in this population.

Fecal continence outcomes and potential disparities for patients with anorectal malformations treated at referral institutions for pediatric colorectal surgery

PURPOSE

Fecal incontinence is a problem for many patients born with an anorectal malformation (ARM) that can impact quality of life. It is unknown if racial, ethnic, and socioeconomic disparities relate to fecal continence in these children. We sought to examine outcomes and potential disparities in care.

METHODS

We performed a multicenter retrospective study of children > 3y with ARM evaluated at sites participating in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC). The primary outcome was fecal continence. We evaluated for associations between fecal continence and race, sex, age, and insurance status.

RESULTS

509 patients with ARM from 11 institutions were included. Overall, 24% reported complete fecal continence, and fecal continence was associated with older age (p < .001). For school-aged children, 27% reported complete continence, while 53% reported none. On univariate analysis, patients with combined private and public insurance showed lower rates of continence when compared to those with private insurance (23 vs. 12%; p = 0.02). Age was associated with continence on univariate and multivariable analyses.

CONCLUSION

Rates of complete fecal continence in this population are low. Differences based on payor status may exist. There were no observed disparities related to sex and race. Further investigation is warranted to improve care for this patient population.

Racial Disparities in Surgical Outcomes of Acute Diverticulitis: Have We Moved the Needle?

INTRODUCTION

There has been increasing national attention on reducing healthcare disparities. Prior studies cite worse surgical outcomes and less use of laparoscopy for Black patients with diverticulitis. Re-evaluation of these disparities is lacking despite national initiatives to improve health equity. This study aimed to evaluate the association of race with short-term outcomes and surgical approaches in patients with acute diverticulitis.

METHODS

The National Surgical Quality Improvement Program database was queried for patients who underwent nonelective surgery for acute diverticulitis from 2015 to 2019. Severity of presentation, morbidity, mortality, surgical approach, and ostomy creation were compared by race.

RESULTS

Of the 13,996 patients included in the study, 82.4% were White, 7.6% were Black, 1.1% Asian, 0.61% American Indian/Alaska Native, and 0.20% Native Hawaiian/Pacific Islander (NH/PI). Overall 30-day morbidity was 44.3% and 30-day mortality was 3.9%. In a multivariate logistic regression analysis, compared to Whites, Black race was independently associated with higher 30-day morbidity (Odds Ratio: 1.24, 95% confidence interval: 1.07-1.43, P = 0.003) and NH/PI race was independently associated with higher mortality (Odds Ratio: 5.35, 95% confidence interval: 1.32-21.6, P = 0.019). There was no difference in complicated disease (abscess or perforation), use of laparoscopy, or ostomy creation among races.

CONCLUSIONS

Despite national efforts to achieve equity in healthcare, disparities persist in surgical outcomes for those with diverticulitis. Black and NH/PI race are independently associated with increased morbidity and mortality, respectively. Use of laparoscopy, however, is no longer different by race suggesting some gaps may be closing.

Towards Equitable Surgical Management of Inflammatory Bowel Disease: A Systematic Review of Disparities in Surgery for Inflammatory Bowel Disease

BACKGROUND

Existing evidence for disparities in inflammatory bowel disease is fragmented and heterogenous. Underlying mechanisms for differences in outcomes based on race and socioeconomic status remain undefined. We performed a systematic review of the literature to examine disparities in surgery for inflammatory bowel disease in the United States.

METHODS

Electronic databases were searched from 2000 through June 11, 2021, to identify studies addressing disparities in surgical treatment for adults with inflammatory bowel disease. Eligible English-language publications comparing the use or outcomes of surgery by racial/ethnic, socioeconomic, geographic, and/or institutional factors were included. Studies were grouped according to whether outcomes of surgery were reported or surgery itself was the relevant end point (utilization). Quality was assessed using the Newcastle-Ottawa Scale for observational studies.

RESULTS

Forty-five studies were included. Twenty-four reported surgical outcomes and 21addressed utilization. Race/ethnicity was considered in 96% of studies, socioeconomic status in 44%, geographic factors in 27%, and hospital/surgeon factors in 22%. Although study populations and end points were heterogeneous, Black and Hispanic patients were less likely to undergo abdominal surgery when hospitalized; they were more likely to have a complication when they did have surgery. Differences based on race were correlated with socioeconomic factors but frequently remained significant after adjustments for insurance and baseline health.

CONCLUSIONS

Surgical disparities based on sociologic and structural factors reflect unidentified differences in multidisciplinary disease management. A broad, multidimensional approach to disparities research with more granular and diverse data sources is needed to improve health care quality and equity for inflammatory bowel disease.

Racial Disparities in 30-Day Outcomes After Colorectal Surgery in an Integrated Healthcare System

BACKGROUND

Racial disparities in colorectal surgery outcomes have been studied extensively in the USA, and access to healthcare resources may contribute to these differences. The Veterans Health Administration (VHA) is the largest integrated healthcare network in the USA with the potential for equal access care to veterans. The objective of this study is to evaluate the VHA for the presence of racial disparities in 30-day outcomes of patients that underwent colorectal resection.

METHODS

Colon and rectal resections from 2008 to 2019 were reviewed retrospectively using the Veterans Affairs Surgical Quality Improvement Program database. Patients were categorized by race and ethnicity. Multivariable analysis was used to compare 30-day outcomes. Cases with "unknown/other/declined to answer" race/ethnicity were excluded.

RESULTS

Thirty-six-thousand-nine-hundred-sixty-nine cases met inclusion criteria: 27,907 (75.5%) Caucasian, 6718 (18.2%) African American, 2047 (5.5%) Hispanic, and 290 (0.8%) Native American patients. There were no statistically significant differences in overall complication incidence or mortality between all cohorts. Compared to Caucasian race, African American patients had longer mean length of stay (10.7 days vs. 9.7 days; p < 0.001). Compared to Caucasian race, Hispanic patients had higher odds of pulmonary-specific complications (adjusted odds ratio with 95% confidence interval = 1.39 [1.17-1.64]; p < 0.001).

CONCLUSIONS

The VHA provides the benefits of integrated healthcare and access, which may explain the improvements in racial disparities compared to existing literature. However, some racial disparities in clinical outcomes still persisted in this analysis. Further efforts beyond healthcare access are needed to mitigate disparities in colorectal surgery.

Racial Disparities in the Management of Locoregional Colorectal Cancer

Racial disparities pervade nearly all aspects of management of locoregional colorectal cancer, including time to treatment, receipt of resection, adequacy of resection, postoperative complications, and receipt of neoadjuvant and adjuvant multimodality therapies. Disparate gaps in treatment translate into enduring effects on survivorship, recurrence, and mortality. Efforts to reduce these gaps in care must be undertaken on a multilevel basis and focus on modifiable factors that underlie racial disparity.

Permanent stoma: a quality outcome in treatment of rectal cancer and its impact on length of stay

BACKGROUND

This study aimed to identify socioeconomic predictors of permanent stoma in rectal cancer treatment and examine its association with length of stay at the treatment facility.

METHODS

Rectal cancer patients who underwent elective surgery between January 2015 and December 2018 were identified from the Agency for Health Care Administration Florida Hospital Inpatient Discharge Dataset. Multivariate regression models were utilized to identify demographic and socioeconomic factors associated with receiving a permanent stoma as well as the associated length of stay of these patients.

RESULTS

Of 2630 rectal cancer patients who underwent surgery for rectal cancer, 21% had a permanent stoma. The odds of receiving permanent stoma increased with higher Elixhauser score, metastatic disease, advanced age, having open surgery, residence in Southwest Florida, and having Medicaid insurance or no insurance/self-payers (p < 0.05). Patients with a permanent stoma had a significantly extended stay after surgery (p < 0.001).

CONCLUSIONS

Patients with a permanent stoma following cancer resection were more likely to have open surgery, had more comorbidities, and had a longer length of stay. Having permanent stoma was higher in patients living in South West Florida, patients with Medicaid insurance, and in the uninsured. Additionally, the payer type significantly affected the length of stay.

Racial Disparities in Outcomes After Common Abdominal Surgical Procedures-The Impact of Access to a Minimally Invasive Approach

BACKGROUND

It is presently considered the standard of care to perform many routine intra-abdominal operations using a minimally invasive approach. The authors recently identified a racial disparity in access to a laparoscopic approach to inguinal hernia repair, cholecystectomy, appendectomy, and colectomy. The present study further evaluates this patient cohort to assess the relationship between the race and postoperative complications and test the mediating effect of the selected surgical approach.

METHODS

After institutional review board approval, patients in the American College of Surgeons National Surgical Quality Improvement Program database who underwent inguinal hernia repair, cholecystectomy, appendectomy, or colectomy in 2016 were identified. Patient demographics, including the self-reported race and ethnicity, as well as clinical, operative, and postoperative variables were recorded. After the exclusion of cases associated with diagnoses of cancer, a 4:1 propensity score matching algorithm generated a clinically balanced cohort of patients of white and black self-reported race. The mediating effect of an open approach to surgery on the relationship between black self-reported race and postoperative complications was evaluated via a series of regressions.

RESULTS

There were 41,340 unilateral inguinal hernia repairs, 3182 bilateral inguinal hernia repairs, 60,444 cholecystectomies, 50,523 appendectomies, and 58,012 colectomies included in the database in 2017. Exclusion of cases associated with cancer and subsequent propensity score matching returned 17,540 unilateral hernia repairs, 890 bilateral hernia repairs, 23,865 cholecystectomies, 11,660 appendectomies, and 12,320 colectomies. On mediation analysis, any complication, severe complication, and death were significant when regressed on black self-reported race (any: odds ratio [OR] = 1.210, 95% confidence interval [CI] = 1.132-1.291, P < 0.001; severe: OR = 1.352, 95% CI = 1.245-1.466, P < 0.001; death: OR = 1.358, 95% CI = 1.000-1.818, P = 0.044), and open surgery was a significant mediator in the incidence of any complication and severe complication (any: OR = 1.180, 95% CI = 1.105-1.260, P < 0.001 and severe: OR = 1.307, 95% CI = 1.203-1.418, P < 0.001).

CONCLUSIONS

These findings underscore the importance of access to a minimally invasive approach to surgery. However, other factors may contribute to racial disparities in postoperative complications after common abdominal operations.
