Social vulnerability is associated with higher risk-adjusted rates of postoperative complications in a broad surgical population. Am J Surg 2024; 229:26-33. [PMID: 37775458 DOI: 10.1016/j.amjsurg.2023.09.028] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 09/08/2023] [Accepted: 09/22/2023] [Indexed: 10/01/2023]
Abstract
OBJECTIVE The purpose of this study was to determine if an association between Social Vulnerability Index (SVI) and risk-adjusted complications exists in a broad spectrum of surgical patients. SUMMARY BACKGROUND DATA Growing evidence supports the impact of social circumstances on surgical outcomes. SVI is a neighborhood-based measure accounting for sociodemographic factors putting communities at risk. METHODS This was a multi-hospital, retrospective cohort study including a sample of patients within one healthcare system (2012-2017). Patient addresses were geocoded to determine census tract of residence and estimate SVI. Patients were grouped into low SVI (score<75) and high SVI (score≥75) cohorts. Perioperative variables and postoperative outcomes were tracked and compared using local ACS-NSQIP data. Multivariable logistic regression was performed to generate risk-adjusted odds ratios of postoperative complications in the high SVI cohort. RESULTS Overall, 31,224 patients from five hospitals were included. Patients with high SVI were more likely to be racial minorities, have 12/18 medical comorbidities, have high ASA class, be functionally dependent, be treated at academic hospitals, and undergo emergency operations (all p < 0.05). Patients with high SVI had significantly higher rates of 30-day mortality, overall morbidity, respiratory, cardiac and infectious complications, urinary tract infections, postoperative bleeding, non-home discharge, and unplanned readmissions (all p < 0.05). After risk-adjustment, only the associations between high SVI and mortality and unplanned readmission became non-significant. CONCLUSIONS High SVI was associated with multiple adverse outcomes even after risk adjustment for preoperative clinical factors. Targeted preventative interventions to mitigate risk of these specific complications should be considered in this high-risk population.

Chalchissa FB, Kuris BK. Modelling soil organic carbon dynamics under extreme climate and land use and land cover changes in Western Oromia Regional state, Ethiopia. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2024; 350:119598. [PMID: 38000272 DOI: 10.1016/j.jenvman.2023.119598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 10/15/2023] [Accepted: 11/10/2023] [Indexed: 11/26/2023]
Abstract
The combined effects of changes in climate and land use and land cover can lead to a decrease in soil organic carbon, potentially affecting soil fertility and agricultural output. The study aimed to evaluate the dynamics of soil organic carbon under various extreme climate and land use and land cover scenarios. The data on land use types and extreme climate indices between 2015 and 2070 were, respectively, sourced from the IPCC and the European Copernicus Climate Change Service webpages. The 2015 baseline data for soil organic carbon was obtained from the African Soil Information Service's website. Data quality control and model validation were conducted to ensure the reliability of the collected data and the predictive model. A generalized regression model was chosen for its accuracy and reliability in predicting soil organic carbon dynamics under different shared socio-economic pathways such as SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios. The study revealed that variations in extreme climate and land use patterns significantly influenced the organic carbon content of the soil. Increased dry days and the conversion of forest and grassland into farmland resulted in a drop in soil organic carbon, while increased wet days and warming temperatures significantly increase it under each scenario. The soil organic carbon content increased by 5.82 and 2.8 g/kg for the SSP1-2.6 and SSP2-4.5 scenarios, respectively, but decreased by 6.90 g/kg under the SSP5-8.5 scenario. Overall, the higher emission scenarios had a significant negative impact on soil organic carbon levels, while the low emission scenarios had a positive impact. Sustainable land management practices are crucial for preserving and managing soil organic carbon levels.

Al-Mansour MR, Gabriel KH, Neal D. Gender, racial, and socioeconomic disparity of preoperative optimization goals in ventral hernia repair. Surg Endosc 2023; 37:9399-9405. [PMID: 37658198 DOI: 10.1007/s00464-023-10365-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Accepted: 07/30/2023] [Indexed: 09/03/2023]
Abstract
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. Am J Surg 2023; 226:580-585. [PMID: 37331908 DOI: 10.1016/j.amjsurg.2023.06.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 05/26/2023] [Accepted: 06/10/2023] [Indexed: 06/20/2023]
Abstract
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.

Community distress as a predictor of early hernia recurrence for older adults undergoing ventral hernia repair (VHR). Surg Endosc 2022:10.1007/s00464-022-09587-y. [PMID: 36138253 PMCID: PMC9510278 DOI: 10.1007/s00464-022-09587-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Accepted: 08/25/2022] [Indexed: 11/05/2022]
Abstract
Background Social cohesion and neighborhood support have been linked to improved health in a variety of fields, but is not well-studied among the elderly population. This is particularly evident in surgical populations. Therefore, this study sought to assess the potential role of community distress in predicting early hernia recurrence among older adults. Methods The Abdominal Core Health Quality Collaborative (ACHQC) was used to identify patients aged 65 or older undergoing elective ventral hernia repair with zip code data available. Patients were linked to the Distressed Communities Index (DCI), which is a national database that assigns a score of 0–100 to each zip code based on 7 measures of neighborhood prosperity. Quintiles were used to compare groups: prosperous (0–20), comfortable (21–40), mid-tier (41–60), at-risk (61–80), and distressed (81–100). Distressed (0–20), at-risk (21–40), mid-tier (41–60), comfortable (61–80), and prosperous (81–100). Time to recurrence for neighborhood distress quintiles was examined using a Cox proportional hazards model. Results In total, 9819 patients were included in the study, including 3056 (31.1%) prosperous, 2307 (23.5%) comfortable, 1795 (18.2%) mid-tier, 1390 (14.2%) at-risk, and 1271 (12.9%) distressed. Distressed communities had lower mean age and greater proportion of racial minorities (p < 0.001). Open repairs were significantly more common among the distressed group (66.7%), as were all comorbidities (p < 0.001). Recurrence-free survival was shorter for distressed communities compared to prosperous after adjusting for baseline characteristics (HR 1.3, 95% CI 1.07–1.67, p = 0.01). Mean time to recurrence was lowest for patients living in distressed communities, indicating the worst recurrence rates, while mean time to recurrence was greatest for those in prosperous zip codes (p < 0.001). Conclusion Older VHR patients presenting from distressed zip codes, as identified by the Distressed Communities Index, experience hernia recurrence significantly sooner as compared to patients from prosperous zip codes. This study may provide evidence of the role of neighborhood and environmental factors in caring for older patients following VHR. Graphical abstract ![]()

Hansen DL, Fonnes S, Rosenberg J. Spin is present in the majority of articles evaluating robot-assisted groin hernia repair: a systematic review. Surg Endosc 2022; 36:2271-2278. [PMID: 35024934 DOI: 10.1007/s00464-021-08990-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Accepted: 12/31/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND The number of scientific articles published each year is increasing, resulting in greater competition to get work published. Spin is defined as specific reporting strategies used to distort the readers' interpretation of results so that they are viewed more favorable. However, prevalence of spin in studies comparing robot-assisted groin hernia repair with traditional methods is unknown. OBJECTIVES/AIM To determine the frequency and extent of spin in studies assessing robot-assisted groin hernia repair. METHODS This systematic review was reported according to PRISMA guidelines, and a protocol was registered at PROSPERO before data extraction. Database search included PubMed, EMBASE, and Cochrane Central. RESULTS Of 35 included studies, spin was present in 57%. Within these, 95% had spin present in the abstract and 80% in the conclusion of the article. There was no association between study size and spin (p > 0.05). However, presence of spin in studies positively minded towards robot-assisted hernia repair was higher (p < 0.001) compared with those against or being neutral in their view of the procedure. Furthermore, being funded by or receiving grants from Intuitive Surgical were associated with a higher prevalence of spin (p < 0.05) compared with those who were not. CONCLUSION Spin was found to be common in articles reporting on robot-assisted groin hernia repair, and presence of spin was higher in studies funded by or receiving grants from the robot company. This suggests that readers should be cautious when reading similar literature.
