Heterogeneity in the surgical approach to recurrent abdominal wall hernias: an opportunity for quality improvement.

BACKGROUND: Despite being a challenging and morbid clinical problem, operative approaches to recurrent abdominal wall hernia repairs receive little attention. Given this, we performed a retrospective study to evaluate surgical techniques of recurrent abdominal wall hernias requiring reoperation. METHODS: Adult patients from the Michigan Surgical Quality Collaborative Core Optimization Hernia Registry (MSQC-COHR) were included in this study. All elective ventral hernia operations performed between January 1, 2020, and March 31, 2023, were included. Descriptive analyses via t-tests and Fisher exact tests were conducted to evaluate sociodemographic, operative, and hernia-specific attributes associated with primary and recurrent hernia repairs. RESULTS: We identified 8587 patients who underwent elective abdominal wall hernia repair. Of these, 7887 (91.8%) underwent primary repair, and 700 (8.2%) underwent recurrent repair. Patients who underwent recurrent hernia repair were older (mean age 57.9 years vs. 54.1 years, p < 0.001), more often female (53.8% vs. 41.9%, p < 0.001), and had higher BMI (34.0 vs. 32.6, p < 0.001). Patients with recurrent hernias were more likely to have comorbid conditions including hypertension (p < 0.001), diabetes (p < 0.005), COPD (p < 0.01), and BMI > 40 (p < 0.05). Recurrent hernia repairs were more likely to have any 30-day complication (6.4% versus 1.9%, p < 0.001), including higher rates of all surgical site infections. There was no difference in 30-day readmission rates. CONCLUSION: Considerable variation persists in operative management of recurrent abdominal wall hernias. Importantly, not all recurrent hernias were managed with mesh, which may precipitate additional recurrences and further morbidity. Understanding outcomes for these varied approaches to recurrent hernia repairs is critical to optimize management of this complex clinical problem and prevent future episodes of recurrence.

Variation in surgical approach and postoperative complication among older adults undergoing ventral hernia repair.

BACKGROUND: Surgical decision-making for preference-sensitive operations among older adults is understudied. Ventral hernia repair (VHR) is one operation where granular data are limited to guide preoperative decision-making. We aimed to determine risk for VHR in older adults given clinically nuanced data including surgical and hernia characteristics. METHODS: We performed a retrospective analysis of the Michigan Surgical Quality Collaborative Core Optimization Hernia Registry from January 2020 to March 2023. The primary outcome was postoperative complication across age groups: 18-64, 65-74, and ≥ 75 years, with secondary outcome of surgical approach. Mixed-effects logistic regression evaluated association between minimally invasive surgery (MIS) and 30-day complications, controlling for patient and hernia characteristics. RESULTS: Among 8,659 patients, only 7% were 75 or older. MIS rates varied across hospitals [Median = 31.4%, IQR: (14.8-51.6%)]. The overall complication rate was 2.2%. Complication risk for undergoing open versus MIS approach did not vary between age groups; however, patients over age 75 undergoing laparoscopic repair had increased risk (aOR = 4.58, 95% CI 1.13-18.67). Other factors associated with risk included female sex (aOR = 2.10, 95% CI 1.51-2.93), higher BMI (aOR = 1.18, 95% CI 1.03-1.34), hernia width ≥ 6 cm (aOR = 3.15, 95% CI 1.96-5.04), previous repair (aOR = 1.44, 95% CI 1.02-2.05), and component separation (aOR = 1.98, 95% CI 1.28-3.05). Patients most likely to undergo MIS were female (aOR = 1.21, 95% CI 1.09-1.34), black (aOR = 1.30, 95% CI 1.12-1.52), with larger hernias: 2-5.9 cm (aOR = 1.76, 95% CI 1.57-1.97), or intraoperative mesh placement (aOR = 14.4, 95% CI 11.68-17.79). There was no difference in likelihood to receive MIS across ages when accounting for hospital (SD of baseline likelihood = 1.53, 95% CI 1.14-2.05) and surgeon (SD of baseline likelihood = 2.77, 95% CI 2.46-3.11) variation. CONCLUSIONS: Our findings demonstrate that hernia, intraoperative, and patient characteristics other than age increase probability for complication following VHR. These findings can empower surgeons and older patients considering preoperative risk for VHR.

Leadership Experiences and Perceptions of Mid-Career to Senior Clinician-Scientists: A Qualitative Exploration.

PURPOSE: This study aimed to elucidate the experiences and perceptions of mid-career to senior clinician-scientists in academic medicine regarding pursuing, attaining, or rejecting leadership roles as well as their conceptualization of the influence of leadership in their broader career trajectories. METHOD: The authors conducted a qualitative analysis of in-depth, semistructured interviews conducted in 2022 with a diverse sample of clinician-scientists who received new National Institutes of Health K08 or K23 Career Development Awards between 2006 and 2009. A total of 859 of the 915 survey respondents (94%) were eligible to be recruited for the qualitative study. Qualitative analysis was informed by thematic analysis and used a social constructionist approach to understanding participants' conceptualizations of their experiences. Interview transcripts were coded using an iterative, inductive coding process. Themes were generated by reviewing coded data and identifying common patterns in participant narratives, affording particular attention to participants' discussion of the effect of race and/or gender on their leadership experiences. RESULTS: Sixty clinician-scientists participated in individual interviews. Five themes were generated surrounding participants' conceptualizations of their leadership experiences. Themes were (1) feeling unprepared for leadership roles, (2) reluctance and lack of intention in attaining leadership positions, (3) influence of networks on leadership access and decision-making, (4) impact-related benefits and downsides of leadership, and (5) confining ideas of who leaders are. CONCLUSIONS: The study highlighted the need for formal leadership training in academic medicine and the importance of mentorship and sponsorship in attaining and succeeding in leadership positions. Individuals from communities underrepresented in leadership positions faced additional challenges internalizing a leadership identity. Efforts to encourage current leaders to engage in intentional succession planning and development of faculty towards leadership roles, including expansion of institutional leadership development programs, are needed to promote equitable distribution of leadership opportunities.

Opportunities and Applications of Educational Technologies in Surgical Education and Assessment.

BACKGROUND: Surgical education is challenged by continuously increasing clinical content, greater subspecialization, and public scrutiny of access to high quality surgical care. Since the last Blue Ribbon Committee on surgical education, novel technologies have been developed including artificial intelligence and telecommunication. OBJECTIVES AND METHODS: The goals of this Blue Ribbon Sub-Committee were to describe the latest technological advances and construct a framework for applying these technologies to improve the effectiveness and efficiency of surgical education and assessment. An additional goal was to identify implementation frameworks and strategies for centers with different resources and access. All sub-committee recommendations were included in a Delphi consensus process with the entire Blue Ribbon Committee (N=67). RESULTS: Our sub-committee found several new technologies and opportunities that are well poised to improve the effectiveness and efficiency of surgical education and assessment (see Tables 1-3). Our top recommendation was that a Multidisciplinary Surgical Educational Council be established to serve as an oversight body to develop consensus, facilitate implementation, and establish best practices for technology implementation and assessment. This recommendation achieved 93% consensus during the first round of the Delphi process. CONCLUSION: Advances in technology-based assessment, data analytics, and behavioral analysis now allow us to create personalized educational programs based on individual preferences and learning styles. If implemented properly, education technology has the promise of improving the quality and efficiency of surgical education and decreasing the demands on clinical faculty.

Implementation science in humanitarian assistance: applying a novel approach for humanitarian care optimization.

Humanitarian assistance is hindered by a lack of strategies to optimize care delivery through research and organized networks. Distinct from global health, humanitarian assistance struggles to address its multifaceted challenges, including duplicative resources, uncoordinated communication, unregulated staff expertise and safety, financial waste, and poor-quality metrics and care delivery. Implementation science provides an exciting and underutilized approach that can be applied to address these challenges, by studying how to effectively design, implement, optimize, and scale evidence-based interventions. Though successful in well-resourced and global health systems, implementation science approaches are rare in humanitarian assistance. Adopting implementation science approaches including identifying determinants, creating accessible evidence-based intervention bundles, adapting study methodologies for the humanitarian context, and partnering with implementation experts could make these promising approaches more accessible for thousands of humanitarian actors delivering healthcare for millions of vulnerable patients worldwide.

Is Preoperative Optimization Right for Every Hernia Patient?: It's Time to Optimize the Optimization Process.

This Viewpoint discusses developing a more nuanced preoperative optimization strategy for hernia repair that considers patient and disease factors to determine the right operation for the right patient at the right time.

Use of statewide financial incentives to improve documentation of hernia and mesh characteristics in ventral hernia repair.

BACKGROUND: Documentation of intraoperative details is critical for understanding and advancing hernia care, but is inconsistent in practice. Therefore, to improve data capture on a statewide level, we implemented a financial incentive targeting documentation of hernia defect size and mesh use. METHODS: The Abdominal Hernia Care Pathway (AHCP), a voluntary pay for performance (P4P) initiative, was introduced in 2021 within the statewide Michigan Surgical Quality Collaborative (MSQC). This consisted of an organizational-level financial incentive for achieving 80% performance on eight specific process measures for ventral hernia surgery, including complete documentation of hernia defect size and location, as well as mesh characteristics and fixation technique. Comparisons were made between AHCP and non-AHCP sites in 2021. RESULTS: Of 69 eligible sites, 47 participated in the AHCP in 2021. There were N = 5362 operations (4169 at AHCP sites; 1193 at non-AHCP sites). At AHCP sites, 69.8% of operations had complete hernia documentation, compared to 50.5% at non-AHCP sites (p < 0.0001). At AHCP sites, 91.4% of operations had complete mesh documentation, compared to 86.5% at non-AHCP sites (p < 0.0001). The site-level hernia documentation goal of 80% was reached by 14 of 47 sites (range 14-100%). The mesh documentation goal was reached by 41 of 47 sites (range 4-100%). CONCLUSIONS: Addition of an organizational-level financial incentive produced marked gains in documentation of intra-operative details across a statewide surgical collaborative. The relatively large effect size-19.3% for hernia-is remarkable among P4P initiatives. This result may have been facilitated by surgeons' direct role in documenting hernia size and mesh use. These improvements in data capture will foster understanding of current hernia practices on a large scale and may serve as a model for improvement in collaboratives nationally.

Variability in surgical approaches to hernias in patients with ascites.

BACKGROUND: Hernias in patients with ascites are common, however we know very little about the surgical repair of hernias within this population. The study of these repairs has largely remained limited to single center and case studies, lacking a population-based study on the topic. STUDY DESIGN: The Michigan Surgical Quality Collaborative and its corresponding Core Optimization Hernia Registry (MSQC-COHR) which captures specific patient, hernia, and operative characteristics at a population level within the state was used to conduct a retrospective review of patients with ascites undergoing ventral or inguinal hernia repair between January 1, 2020 and May 3, 2022. The primary outcome observed was incidence and surgical approach for both ventral and inguinal hernia cohorts. Secondary outcomes included 30-day adverse clinical outcomes as listed here: (ED visits, readmission, reoperation and complications) and surgical priority (urgent/emergent vs elective). RESULTS: In a cohort of 176 patients with ascites, surgical repair of hernias in patients with ascites is a rare event (1.4% in ventral hernia cohort, 0.2% in inguinal hernia cohort). The post-operative 30-day adverse clinical outcomes in both cohorts were greatly increased compared to those without ascites (ventral: 32% inguinal: 30%). Readmission was the most common complication in both inguinal (n = 14, 15.9%) and ventral hernia (n = 17, 19.3%) groups. Although open repair was most common for both cohorts (ventral: 86%, open: 77%), minimally invasive (MIS) approaches were utilized. Ventral hernias presented most commonly urgently/emergently (60%), and in contrast many inguinal hernias presented electively (72%). CONCLUSION: A population-level, ventral and incisional hernia database capturing operative details for 176 patients with ascites. There was variation in the surgical approaches performed for this rare event and opportunities for optimization in patient selection and timing of repair.

Mesh overlap for ventral hernia repair in current practice.

INTRODUCTION: Sufficient overlap of mesh beyond the borders of a ventral hernia helps prevent hernia recurrence. Guidelines from the European Hernia Society and American Hernia Society recommend ≥ 2 cm overlap for open repair of < 1-cm hernias, ≥ 3-cm overlap for open repair of 1-4-cm hernias, ≥ 5-cm overlap for open repair of > 4-cm hernias, and ≥ 5-cm overlap for all laparoscopic ventral hernia repairs. We evaluated whether current practice reflects this guidance. METHODS: We used the Michigan Surgical Quality Collaborative Hernia Registry to evaluate patients who underwent elective ventral and umbilical hernia repair between 2020 and 2022. Mesh overlap was calculated as [(width of mesh - width of hernia)/2]. The main outcome was "sufficient overlap," defined based on published EHS and AHS guidelines. Explanatory variables included patient, operative, and hernia characteristics. The main analysis was a multivariable logistic regression to evaluate the association between explanatory variables and sufficient mesh overlap. RESULTS: 4178 patients underwent ventral hernia repair with a mean age of 55.2 (13.9) years, 1739 (41.6%) females, mean body mass index (BMI) of 33.1 (7.2) kg/m2, and mean hernia width of 3.7 (3.4) cm. Mean mesh overlap was 3.7 (2.5) cm and ranged from - 5.5 to 21.4 cm. Only 1074 (25.7%) ventral hernia repairs had sufficient mesh overlap according to published guidelines. Operative factors associated with increased odds of sufficient overlap included myofascial release (adjusted odds ratio [aOR] 5.35 [95% CI 4.07-7.03]), minimally invasive approach (aOR 1.86 [95% CI 1.60-2.17]), and onlay mesh location (aOR 1.31 [95% CI 1.07-1.59]). Patient factors associated with increased odds of sufficient overlap included prior hernia repair (aOR 1.59 [95% CI 1.32-1.92]). CONCLUSION: Although sufficient mesh overlap is recommended to prevent ventral hernia recurrence, only a quarter of ventral hernia repairs in a state-wide cohort of patients had sufficient overlap according to evidence-based guidelines. Factors strongly associated with sufficient overlap included myofascial release, mesh type, and laparoscopic repair.

Life after "no": barriers to behavior change for persons declined hernia repair due to high-risk features.

INTRODUCTION: Delaying an elective operation to mitigate risk factors improves patient outcomes. Elective ventral hernia repair is one such example. To address this issue, we developed a pre-operative optimization clinic to support high-risk patients seeking elective ventral hernia repair. Unfortunately, few patients progressed to surgery. Within this context, we sought to understand the barriers to behavior change among these patients with the goal of improving care for patients undergoing elective surgery. METHODS: We performed semi-structured, qualitative interviews with 20 patients who were declined ventral hernia repair due to either active tobacco use or obesity. Patients were recruited from a pre-operative optimization clinic at an academic hospital. Interviews sought to characterize patients' perceived barriers to behavior change. Interviews were concluded once thematic saturation was reached. We used an inductive thematic analysis to analyze the data. All data analysis was performed using MAXQDA software. RESULTS: Among 20 patients (mean age 50, 65% female, 65% White), none had yet undergone ventral hernia repair. While most patients had a positive experience in the clinic, among those who did not, we found three dominant themes around behavior change: (1) Patient's role in behavior change: how the patient perceived their role in making behavior changes optimize their health for surgery; (2) Obtainability of offered resources: the need for more support for patients to access the recommended healthcare; and (3) Patient-provider concordance: the extent to which patients and providers agree on the relative importance of different attributes of their care. CONCLUSION: Behavior change prior to elective surgery is complex and multifaceted. While improving access to tobacco cessation resources and obesity management may improve outcomes for some, patients may benefit from increased on-site facilitation to promote access to resources as well as the use of patient-facing decision support tools to promote patient-provider concordance.

Workplace Harassment, Cyber Incivility, and Climate in Academic Medicine.

Importance: The culture of academic medicine may foster mistreatment that disproportionately affects individuals who have been marginalized within a given society (minoritized groups) and compromises workforce vitality. Existing research has been limited by a lack of comprehensive, validated measures, low response rates, and narrow samples as well as comparisons limited to the binary gender categories of male or female assigned at birth (cisgender). Objective: To evaluate academic medical culture, faculty mental health, and their relationship. Design, Setting, and Participants: A total of 830 faculty members in the US received National Institutes of Health career development awards from 2006-2009, remained in academia, and responded to a 2021 survey that had a response rate of 64%. Experiences were compared by gender, race and ethnicity (using the categories of Asian, underrepresented in medicine [defined as race and ethnicity other than Asian or non-Hispanic White], and White), and lesbian, gay, bisexual, transgender, queer (LGBTQ+) status. Multivariable models were used to explore associations between experiences of culture (climate, sexual harassment, and cyber incivility) with mental health. Exposures: Minoritized identity based on gender, race and ethnicity, and LGBTQ+ status. Main Outcomes and Measures: Three aspects of culture were measured as the primary outcomes: organizational climate, sexual harassment, and cyber incivility using previously developed instruments. The 5-item Mental Health Inventory (scored from 0 to 100 points with higher values indicating better mental health) was used to evaluate the secondary outcome of mental health. Results: Of the 830 faculty members, there were 422 men, 385 women, 2 in nonbinary gender category, and 21 who did not identify gender; there were 169 Asian respondents, 66 respondents underrepresented in medicine, 572 White respondents, and 23 respondents who did not report their race and ethnicity; and there were 774 respondents who identified as cisgender and heterosexual, 31 as having LGBTQ+ status, and 25 who did not identify status. Women rated general climate (5-point scale) more negatively than men (mean, 3.68 [95% CI, 3.59-3.77] vs 3.96 [95% CI, 3.88-4.04], respectively, P < .001). Diversity climate ratings differed significantly by gender (mean, 3.72 [95% CI, 3.64-3.80] for women vs 4.16 [95% CI, 4.09-4.23] for men, P < .001) and by race and ethnicity (mean, 4.0 [95% CI, 3.88-4.12] for Asian respondents, 3.71 [95% CI, 3.50-3.92] for respondents underrepresented in medicine, and 3.96 [95% CI, 3.90-4.02] for White respondents, P = .04). Women were more likely than men to report experiencing gender harassment (sexist remarks and crude behaviors) (71.9% [95% CI, 67.1%-76.4%] vs 44.9% [95% CI, 40.1%-49.8%], respectively, P < .001). Respondents with LGBTQ+ status were more likely to report experiencing sexual harassment than cisgender and heterosexual respondents when using social media professionally (13.3% [95% CI, 1.7%-40.5%] vs 2.5% [95% CI, 1.2%-4.6%], respectively, P = .01). Each of the 3 aspects of culture and gender were significantly associated with the secondary outcome of mental health in the multivariable analysis. Conclusions and Relevance: High rates of sexual harassment, cyber incivility, and negative organizational climate exist in academic medicine, disproportionately affecting minoritized groups and affecting mental health. Ongoing efforts to transform culture are necessary.

Comparison of safety and healthcare utilization following sleeve gastrectomy or gastric bypass among medicare beneficiaries using sex as a biologic variable.

BACKGROUND: Bariatric surgery is a common operation, but differences in outcomes between males and females are unknown. OBJECTIVES: To compare the risk of mortality, complications, reintervention, and healthcare utilization after sleeve gastrectomy or gastric bypass using sex as a biologic variable. SETTING: United States. METHODS: Retrospective cohort study of adults undergoing sleeve gastrectomy or gastric bypass from January 1, 2012 to December 31, 2018 using Medicare claims data. We performed a heterogeneity of treatment effect analysis to determine the impact of sleeve gastrectomy versus gastric bypass comparing males to females. The primary outcome was safety (mortality, complications, and reinterventions) up to 5 years after surgery. The secondary outcome was healthcare utilization (hospitalization and emergency department use). RESULTS: Among 95,405 patients the majority (n = 71,348; 74.8%) were female and most (n = 57,008; 59.8%) underwent sleeve gastrectomy. For all patients, compared to gastric bypass, sleeve gastrectomy was associated with a lower risk of complications and reintervention but a higher risk of revision. Compared to gastric bypass, sleeve gastrectomy was associated with a lower risk of mortality for females (adjusted hazard ratio .86, 95% CI .75-.96) but not males. We found no difference in procedure treatment effect by sex for mortality, hospitalization, emergency department use, or overall reintervention when comparing sleeve to gastric bypass. CONCLUSIONS: Females and males have similar outcomes following bariatric surgery. Females have a lower risk of complications but a higher risk of reintervention. Decisions surrounding treatment for this common procedure should be tailored to include a discussion of sex-specific differences in treatment outcome.

Surgeon behaviors related to engaging patients in smoking cessation at the time of elective surgery.

BACKGROUND: Despite the abundance of evidence supporting smoking cessation before elective surgery, there is wide variation in surgeon adherence to these best practices. METHODS: This qualitative study used convenience sampling to recruit General Surgery trained surgeons. Surgeons participated in semi-structured interviews based on domains from the Theoretical Domains Framework (TDF). Content analysis was guided by the TDF. RESULTS: Of the 14 TDF domains, social or professional role/identity, memory, attention and decision processes, environmental context and resources, and beliefs about consequences emerged most frequently. Mapping these domains to the Behavior Change Wheel identified education, enablement, and incentivization as effective intervention functions. CONCLUSIONS: Using the TDF, this study identified a widespread sense of responsibility among surgeons to engage patients in perioperative smoking cessation despite workplace barriers and lacking resources. These findings provide valuable insight to facilitate surgeon participation in health promotion through targeted, theory-based interventions informed by surgeon identified barriers to perioperative smoking cessation.

A qualitative analysis describing attrition from bariatric surgery to identify strategies for improving retention in patients who desire treatment.

BACKGROUND: Among patients who express interest in bariatric surgery, dropout rates from bariatric surgery programs are reported as high as 60%. There is a lack of understanding how we can better support patients to obtain treatment of this serious chronic disease. METHODS: Semi-structured interviews with individuals who dropped out of bariatric surgery programs from three clinical sites were conducted. Transcripts were iteratively analyzed to understand patterns clustering around codes. We mapped these codes to domains of the Theoretical Domains Framework (TDF) which will serve as the basis of future theory-based interventions. RESULTS: Twenty patients who self-identified as 60% female and 85% as non-Hispanic White were included. The results clustered around codes of "perceptions of bariatric surgery," "reasons for not undergoing surgery," and "factors for re-considering surgery." Major drivers of attrition were burden of pre-operative workup requirements, stigma against bariatric surgery, fear of surgery, and anticipated regret. The number and time for requirements led patients to lose their initial optimism about improving health. Perceptions regarding being seen as weak for choosing bariatric surgery, fear of surgery itself, and possible regret over surgery grew as time passed. These drivers mapped to four TDF domains: environmental context and resources, social role and identity, emotion, and beliefs about consequences, respectively. CONCLUSIONS: This study uses the TDF to identify areas of greatest concern for patients to be used for intervention design. This is the first step in understanding how we best support patients who express interest in bariatric surgery achieve their goals and live healthier lives.

Comparative Outcomes of Groin Hernia Repair by Sex Among Medicare Beneficiaries.

OBJECTIVE: To compare the rates of operative recurrence between male and female patients undergoing groin hernia repair. BACKGROUND DATA: Groin hernia repair is common but understudied in females. Limited prior work demonstrates worse outcomes among females. METHODS: Using Medicare claims, we performed a retrospective cohort study of adult patients who underwent elective groin hernia repair between January 1, 2010 and December 31, 2017. We used a Cox proportional hazards model to evaluate the risk of operative recurrence up to 5 years following the index operation. Secondary outcomes included 30-day complications following surgery. RESULTS: Among 118,119 patients, females comprised the minority of patients (n=16,056, 13.6%). Compared with males, female patients were older (74.8 vs. 71.9 y, P <0.01), more often white (89.5% vs. 86.7%, P <0.01), and had a higher prevalence of nearly all measured comorbidities. In the multivariable Cox proportional hazards model, we found that female patients had a significantly lower risk of operative recurrence at 5-year follow-up compared with males (aHR 0.70, 95% CI 0.60-0.82). The estimated cumulative incidence of recurrence was lower among females at all time points: 1 year [0.68% (0.67-0.68) vs. 0.88% (0.88-0.89)], 3 years [1.91% (1.89-1.92) vs. 2.49% (2.47-2.5)], and 5 years [2.85% (2.82-2.88) vs. 3.7% (3.68-3.75)]. We found no significant difference in the 30-day risk of complications. CONCLUSIONS: We found that female patients experienced a lower risk of operative hernia recurrence following elective groin hernia repair, which is contrary to what is often reported in the literature. However, the risk of operative recurrence was low overall, indicating excellent surgical outcomes among older adults for this common surgical condition.

Contemporary Outcomes of Elective Parastomal Hernia Repair in Older Adults.

Importance: Parastomal hernia is a challenging complication following ostomy creation; however, the incidence and long-term outcomes after elective parastomal hernia repair are poorly characterized. Objective: To describe the incidence and long-term outcomes after elective parastomal hernia repair. Design, Setting, and Participants: Using 100% Medicare claims, a retrospective cohort study of adult patients who underwent elective parastomal hernia repair between January 1, 2007, and December 31, 2015, was performed. Logistic regression and Cox proportional hazards models were used to evaluate mortality, complications, readmission, and reoperation after surgery. Analysis took place between February and May 2022. Exposures: Parastomal hernia repair without ostomy resiting, parastomal hernia repair with ostomy resiting, and parastomal hernia repair with ostomy reversal. Main Outcomes and Measures: Mortality, complications, and readmission within 30 days of surgery and reoperation for recurrence (parastomal or incisional hernia repair) up to 5 years after surgery. Results: A total of 17 625 patients underwent elective parastomal hernia repair (mean [SD] age, 73.3 [9.1] years; 10 059 female individuals [57.1%]). Overall, 7315 patients (41.5%) underwent parastomal hernia repair without ostomy resiting, 2744 (15.6%) underwent parastomal hernia repair with ostomy resiting, and 7566 (42.9%) underwent parastomal hernia repair with ostomy reversal. In the 30 days after surgery, 676 patients (3.8%) died, 7088 (40.2%) had a complication, and 1740 (9.9%) were readmitted. The overall adjusted 5-year cumulative incidence of reoperation was 21.1% and was highest for patients who underwent parastomal hernia repair with ostomy resiting (25.3% [95% CI, 25.2%-25.4%]) compared with patients who underwent parastomal hernia repair with ostomy reversal (18.8% [95% CI, 18.7%-18.8%]). Among patients whose ostomy was not reversed, the hazard of repeat parastomal hernia repair was the same for patients whose ostomy was resited vs those whose ostomy was not resited (adjusted hazard ratio, 0.93 [95% CI, 0.81-1.06]). Conclusions and Relevance: In this study, more than 1 in 5 patients underwent another parastomal or incisional hernia repair within 5 years of surgery. Although this was lowest for patients who underwent ostomy reversal at their index operation, ostomy resiting was not superior to local repair. Understanding the long-term outcomes of this common elective operation may help inform decision-making between patients and surgeons regarding appropriate operative approach and timing of surgery.
