Disparities in Access to Oncologic Care in Pancreatic Cancer: A Systematic Review.

BACKGROUND: Pancreatic cancer care is complex, and multiple disparities in receipt of therapies have been documented. The authors aimed to conduct a systematic review of the literature to critically assess and summarize disparities in access to oncologic therapies for pancreatic cancer. METHODS: A search of PubMed, Scopus, Web of Science, and Cochrane databases were performed for studies reporting disparities in access to oncologic care for pancreatic cancer. Primary research articles published in the United States from 2000 to 2020 were included. Data were independently extracted, and risk of bias was assessed using the modified Newcastle-Ottawa scale. RESULTS: The inclusion criteria were met by 47 studies. All the studies used retrospective data, with 70 % involving national database studies, 41 assessing the impact of race/ethnicity, 22 assessing the impact of socioeconomic status, 18 assessing the impact of insurance status, 23 assessing the impact of gender, 26 assessing the impact of age, and 3 assessing the impact of location on the delivery of cancer-directed therapies. Race, socioeconomic status, insurance status, gender, and age- based disparities in receipt of surgical resection, treatment at high-volume facilities and multimodal therapy for resectable pancreatic cancer, receipt of systemic chemotherapy for metastatic cancer, and receipt of expected standard-of-care treatment are reported. CONCLUSION: Significant sociodemographic disparities in access to equitable oncologic care exist along the continuum of pancreatic cancer care. Multiple patient, provider, and systemic factors contribute to these disparities. The ongoing study of these disparities is important to elucidate processes that may be targeted to improve access to equitable oncologic care for patients with pancreatic cancer.

Association of Medicaid Expansion with Pancreatic Cancer Treatment and Outcomes: Evidence from the National Cancer Database.

BACKGROUND: Socioeconomic- and demographic-based disparities exist in the treatment of pancreatic adenocarcinoma (PDAC). Medicaid expansion (ME) may have an impact on these disparities. Analyses of patients with PDAC from the National Cancer Database (NCDB) were performed to examine the impact of ME on access to treatment and outcomes. METHODS: Patients with non-metastatic PDAC diagnosed between 2006 and 2016 were identified. Multiple logistic regression analyses were performed to evaluate factors associated with curative-intent surgical resection, multimodal therapy, treatment at a high-volume facility (HVF), and survival. RESULTS: The study identified 41,876 patients who met the criteria. Medicaid expansion was independently associated with curative-intent resection (odds ratio [OR] 1.54; 95 % confidence interval [CI] 1.43-1.67; p < 0.001). In a multivariable analysis, ME was independently associated with multimodal therapy (OR 1.60; 95 % CI 1.44-1.76; p < 0.001) and treatment at an HVF (OR 1.57; 95 % CI 1.42-1.74; p < 0.001). Medicaid expansion was independently associated with improved 30-day mortality (OR 0.49; 95 % CI 0.34-0.79) and 90-day mortality (OR 0.48 95 % CI 0.35-0.59). Cox regression analysis demonstrated that after adjustment for other variables, ME status was associated with improved overall survival (hazard ratio [HR], 0.82; 95 % CI 0.73-0.90; p < 0.001). CONCLUSIONS: Medicaid expansion is associated with increased use of care processes that improve outcomes in PDAC, operative outcomes, and overall survival. The study data suggest that ME has helped to improve disparities in PDAC in ME states.

Gender Disparity in Surgery: An Evaluation of Surgical Societies.

Background: The percentage of female surgeons and surgery residents has increased slowly to 24% and 35%, respectively. However, women remain under-represented in surgical leadership positions (<20%). Society awards and leadership positions are used for hiring and promoting surgeons. We hypothesized that within the Surgical Infection Society (SIS), females are under-represented. Methods: The SIS website and databases were consulted for the number of female members, awardees, and leaders. Representation was divided into four time periods: 2000-2005, 2006-2010, 2011-2015, and 2016-2017 and compared for changes over time utilizing a Χ2 test. In addition, we reviewed the council members of five other surgical societies and compared the percentage of female representation in leadership positions. Results: Since the SIS was founded, there have been 587 members of whom only 135 (23%) are female. There has been an increase in female membership over time (p < 0.001). The number of female awardees rose from 37% during the first two study periods to more than 50% in the last two periods (p = 0.002). However, female representation in leadership positions decreased from 26% in 2000-2005 to less than 15% in the last three study periods (p = 0.234). Similar disparities emerged when comparing the SIS with other surgical societies: Women have represented only 24% (range 8%-42%) of leaders and 4% (range 0-11%) of society presidents. Conclusions: Female surgeons are under-represented in the SIS membership and leadership positions. Whereas the number of female surgeons and residents has increased, these trends have not occurred with council membership and leadership within the SIS. There is a need to address this gender disparity.

The Effect of Financial Conflict of Interest, Disclosure Status, and Relevance on Medical Research from the United States.

BACKGROUND: Financial interactions between industry and healthcare providers are reportable. Substantial discrepancies have been detected between industry and self-report of these conflicts of interest (COIs). OBJECTIVE: Our aim was to determine if authors who fail to disclose reportable COI are more likely to publish findings that are favorable to industry than authors with no COI. DESIGN: In this blinded, observational study of medical and surgical primary research articles in PubMed, 590 articles were reviewed. MAIN MEASURES: Reportable financial relationships between authors and industry were evaluated. COIs were considered to have relevance if they were associated with the product(s) mentioned by an article. Primary outcome was favorability, defined as an impression favorable to the product(s) discussed by an article and determined by 3 independent, blinded clinicians for each article. Primary analysis compared Incomplete Self-Disclosure to No COI. Two-level multivariable mixed-effects ordered logistic regression was used to assess factors associated with favorability. KEY RESULTS: A 69% discordance rate existed between industry and self-report in COI disclosure. When authors failed to disclose COI, their conclusions were more likely to favor industry partners than authors without COI (favorable ratings 73% versus 62%, RR 1.18, p = < 0.001). On univariate (any COI 74% versus no COI 62%, RR 1.11, p = < 0.001) and multivariable analyses, any COI was associated with favorability. CONCLUSIONS: All financial COIs (disclosed or undisclosed, relevant or not relevant, research or non-research) influence whether studies report findings favorable to industry sponsors.

Epidemiology and Disparities in Care: The Impact of Socioeconomic Status, Gender, and Race on the Presentation, Management, and Outcomes of Patients Undergoing Ventral Hernia Repair.

More research is needed with regards to gender, race, and socioeconomic status on ventral hernia presentation, management, and outcomes. The role of culture and geography in hernia-related health care remains unknown. Currently existing nationwide registries have thus far yielded at best a modest overview of disparities in hernia care. The significant variation in care relative to gender, race, and socioeconomic status suggests that there is room for improvement in providing consistent care for patients with hernias.

Clinical assessment, radiographic imaging, and patient self-report for abdominal wall hernias.

BACKGROUND: Increasingly, abdominal wall hernias are being diagnosed incidentally through radiographic imaging. Such hernias are referred to as occult. However, the clinical significance of occult hernias is unknown. The objective of this study is to determine the prevalence of occult hernias and to assess the abdominal wall quality of life (AW-QOL) among patients with occult hernias. MATERIALS AND METHODS: A blinded, observational, cross-sectional study, October-December 2016, of patients presenting to single academic institution's general surgery clinics was performed. Inclusion criteria included all patients with a computed tomography scan of the abdomen or pelvis within the last year with no intervening abdominal or pelvic surgery. Patients were administered a validated AW-QOL survey and underwent a standardized clinical examination. Computed tomography scans were reviewed. Primary outcomes were prevalence and AW-QOL measured by the modified Activities Assessment Scale. AW-QOL of patients with no hernias was compared to that of those with occult hernias and clinically apparent hernias using Mann-Whitney U test. RESULTS: A total of 250 patients were enrolled of whom 97 (38.8%) had a hernia noted on clinical examination and 132 (52.8%) had a hernia noted on radiographic imaging. The prevalence of occult hernias was 38 (15.2%). Patients with no hernia had a median (interquartile range) AW-QOL of 82.5 (55.0-95.3), patients with clinically apparent hernias had AW-QOL of 47.7 (31.2-81.6; P < 0.001), and patients with occult hernias had AW-QOL of 72.4 (38.5-97.2; P = 0.36). CONCLUSIONS: Both clinically apparent and occult hernias are prevalent. However, only patients with clinically apparent hernias had differences in AW-QOL when compared to patients with no hernias. Prospective trials are needed to assess the outcomes of patients with occult hernias managed with and without surgical repair.

The Impact of Financial Conflict of Interest on Surgical Research: An Observational Study of Published Manuscripts.

BACKGROUND: Substantial discrepancies exist between industry-reported and self-reported conflicts of interest (COI). Although authors with relevant, self-reported financial COI are more likely to write studies favorable to industry sponsors, it is unknown whether undisclosed COI have the same effect. We hypothesized that surgeons who fail to disclose COI are more likely to publish findings that are favorable to industry than surgeons with no COI. METHODS: PubMed was searched for articles in multiple surgical specialties. Financial COI reported by surgeons and industry were compared. COI were considered to be relevant if they were associated with the product(s) mentioned by an article. Primary outcome was favorability, which was defined as an impression favorable to the product(s) discussed by an article and was determined by 3 independent, blinded clinicians for each article. Primary analysis compared incomplete self-disclosure to no COI. Ordered logistic multivariable regression modeling was used to assess factors associated with favorability. RESULTS: Overall, 337 articles were reviewed. There was a high rate of discordance in the reporting of COI (70.3%). When surgeons failed to disclose COI, their conclusions were significantly more likely to favor industry than surgeons without COI (RR 1.2, 95% CI 1.1-1.4, p < 0.001). On multivariable analysis, any COI (regardless of relevance, disclosure, or monetary amount) were significantly associated with favorability. CONCLUSIONS: Any financial COI (disclosed or undisclosed, relevant or not relevant) significantly influence whether studies report findings favorable to industry. More attention must be paid to improving research design, maximizing transparency in medical research, and insisting that surgeons disclose all COI, regardless of perceived relevance.

Investigation of Financial Conflict of Interest among Published Ventral Hernia Research.

BACKGROUND: Discordance exists between author self-disclosure and the Open Payments Database in various surgical fields, but the effects of this discordance on study design and presentation are unknown. We hypothesized that, among ventral hernia publications, discordance exists between industry and physician self-reported conflicts of interest (COIs); authors disclose relevant COIs; and disclosure and relevant COIs affect study favorability. STUDY DESIGN: We conducted a double-blinded, prospective, observational study of published articles. PubMed was searched in reverse chronological order for clinical articles pertaining to ventral hernias. Authors' self-disclosed conflicts were compared with those on the Open Payments Database. Two reviewers blinded to article disclosure status determined jointly whether the COIs were relevant to the article. Three blinded referees independently voted whether each article was favorable to discussed subject matter. The primary end point was study favorability. Secondary outcomes included disclosure status and relevance. RESULTS: One hundred articles were included. Compared with authors with no COIs, authors with a COI, self-disclosed or not, were twice as likely to write results favorable to industry. Of those with a COI, most of the articles had a relevant COI (37 of 45 [82.2%]), and 25% of relevant COIs were not disclosed by authors. Among authors with a relevant COI, study favorability remained unchanged at 68.5% (control: no COI 33.3%; p < 0.001). CONCLUSIONS: Within the ventral hernia literature, 70% of articles have a COI. Self-reporting of COI is discordant in 63% of articles. Twenty-five percent of relevant COI are not disclosed. Having a COI increases the chances that an article will cast a favorable impression on the company paying the authors by 200%.

Discordance of conflict of interest self-disclosure and the Centers of Medicare and Medicaid Services.

BACKGROUND: The Open Payments Database (OPD) discloses financial transactions between manufacturers and physicians. The concordance of OPD versus self-reported conflicts of interest (COI) is unknown. MATERIALS AND METHODS: Our objectives were to compare (1) industry and self-disclosed COI in clinical literature, (2) payments within each disclosure level, and (3) industry- and self-disclosed COI and payments by specialty. This was an observational study. PubMed was searched for clinical studies accepted for publication from January 2014 to June 2016. Author and OPD-disclosed COIs were compared. Articles and authors were divided into full disclosure, incomplete industry disclosure, incomplete self-disclosure, and no COI. Primary outcome (differences in reported COI per article) was assessed using McNemar's test. Payment differences were compared using Kruskal-Wallis test. RESULTS: OPD- and self-disclosed COI differed (65.0% discordance rate by article, P < 0.001). Percentages of authors within each disclosure category differed between specialties (P < 0.001). Hematology articles exhibited the highest discordance rate (79.0%) and received the highest median payment for incomplete self-disclosure ($30,812). CONCLUSIONS: Significant discordance exists between self- and OPD-reported COI. Additional research is needed to determine reasons for these differences.

Comparison of Conflicts of Interest among Published Hernia Researchers Self-Reported with the Centers for Medicare and Medicaid Services Open Payments Database.

BACKGROUND: Many healthcare providers have financial interests and relationships with healthcare companies. To maintain transparency, investigators are expected to disclose their conflicts of interest (COIs). Recently, the Centers for Medicare and Medicaid Services developed the Open Payment database of COIs reported by industry. We hypothesize that there is discordance between industry-reported and physician self-reported COIs in ventral hernia publications. STUDY DESIGN: PubMed was searched for ventral hernia studies accepted for publication between June 2013 and October 2015 and published by authors from the US. Conflicts of interest were defined as payments received as honoraria, consulting fees, compensation for serving as faculty or as a speaker at a venue, research funding payments, or having ownerships/partnerships in companies. Conflicts of interest disclosed on the published articles were compared with the financial relationships in the Open Payments database. RESULTS: A total of 100 studies were selected with 497 participating authors. Information was available from the Open Payments database for 245 (49.2%) authors, of which 134 (26.9%) met the definition for COI. When comparing COIs disclosed by authors and data in the Open Payments database, 81 (16.3%) authors had at least 1 COI but did not declare any, 35 (7.0%) authors had COIs other than what they declared, and 20 (4.0%) declared a COI not listed in the Open Payments database, for a combined discordance rate of 27.3%. CONCLUSIONS: There is substantial discordance between self-reported COI in published articles compared with those in the Centers for Medicare and Medicaid Services Open Payments database. Additional studies are needed to determine the reasons for these differences, as COI can influence the validity of the design, conduct, and results of a study.

Readability Assessment of Internet-Based Patient Education Materials Related to Parathyroid Surgery.

OBJECTIVES: Patient education is critical in obtaining informed consent and reducing preoperative anxiety. Written patient education material (PEM) can supplement verbal communication to improve understanding and satisfaction. Published guidelines recommend that health information be presented at or below a sixth-grade reading level to facilitate comprehension. We investigate the grade level of online PEMs regarding parathyroid surgery. METHODS: A popular internet search engine was used to identify PEM discussing parathyroid surgery. Four formulas were used to calculate readability scores: Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FKGL), Gunning Frequency of Gobbledygook (GFOG), and Simple Measure of Gobbledygook (SMOG). RESULTS: Thirty web-based articles discussing parathyroid surgery were identified. The average FRE score was 42.8 (±1 standard deviation [SD] 16.3; 95% confidence interval [CI], 36.6-48.8; range, 6.1-71.3). The average FKGL score was 11.7 (±1 SD 3.3; 95% CI, 10.5-12.9; range, 6.1-19.0). The SMOG scores averaged 14.2 (±1 SD 2.6; 95% CI, 13.2-15.2; range, 10.7-21.9), and the GFOG scores averaged 15.0 (±1 SD 3.5; 95% CI, 13.7-16.3; range, 10.6-24.8). CONCLUSION: Online PEM on parathyroid surgery is written above the recommended sixth-grade reading level. Improving readability of PEM may promote better health education and compliance.

Readability assessment of Internet-based patient education materials related to acoustic neuromas.

OBJECTIVE: The objectives of this study were to assess the readability of Internet-based patient education materials related to acoustic neuromas (AN-IPEMs) by 4 widely validated readability indices, to evaluate scores against the existing sixth grade recommended reading level, and to compare the readability scores of patient education materials (PEMs) produced by professional organizations, clinical practices, hospitals, and miscellaneous sources. MATERIALS AND METHODS: AN-IPEMs from 67 web sites (6 professional societies, 33 clinical practices, 19 hospitals, and 9 miscellaneous) were assessed using Flesch Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (Gunning FOG). Scores were then evaluated against national recommendations by 1-tailed t tests and against each other using 1-way ANOVAs. RESULTS: The average FKGL, SMOG, and Gunning FOG scores were all significantly higher than the recommended sixth grade reading level suggested by the USDHHS (p < 0.0001, single sample 1-tailed t test). Zero articles, by all indices, had a reading level equal to or below the sixth grade reading level. The FKGLs also varied between the various sources at a significant level (p = 0.01 one-way ANOVA independent samples). The average FKGLs of clinical practice and professional society AN-IPEMs were significantly higher than the average FKGLs of hospital AN-IPEMs (both p ≤ 0.05 one-tailed t-tests assuming unequal variances). CONCLUSION: AN-IPEMs are written at a level significantly higher than that suggested by national recommendations. Current AN-IPEMs may need to be revised in order to enhance patient comprehension.

Gender disparities in research productivity among 9952 academic physicians.

OBJECTIVES/HYPOTHESIS: The number of women in medicine has increased considerably over the past 3 decades, and they now comprise approximately half of medical school matriculants. We examine whether gender disparities in research productivity are present throughout various specialties and compare these findings to those previously described among otolaryngologists. STUDY DESIGN: Bibliometric analysis. METHODS: Research productivity, measured by the h-index, was calculated for 9,952 academic physicians representing 34 medical specialties. Additionally, trends in how rate of research productivity changed throughout different career stages were compared. RESULTS: Women were underrepresented at the level of professor and in positions of departmental leadership relative to their representation among assistant and associate professors. Male faculty had statistically higher research productivity both overall (H = 10.3 ± 0.14 vs. 5.6 ± 0.14) and at all academic ranks. For the overall sample, men and women appeared to have equivalent rates of research productivity. In internal medicine, men had higher early-career productivity, while female faculty had productivity equaling and even surpassing that of their male colleagues beyond 20 to 25 years. Men and women had equivalent productivity in surgical specialties throughout their careers, and similar rates in pediatrics until 25 to 30 years. CONCLUSIONS: Female academic physicians have decreased research productivity relative to men, which may be one factor contributing to their underrepresentation at the level of professor and departmental leader relative to their proportions in junior academic ranks. Potential explanations may include fewer woman physicians in the age groups during which higher academic ranks are attained, greater family responsibilities, and greater involvement in clinical service and educational contributions.

Readability assessment of online thyroid surgery patient education materials.

BACKGROUND: Published guidelines recommend written health information be written at or below the sixth-grade level. We evaluate the readability of online materials related to thyroid surgery. METHODS: Thyroid surgery materials were evaluated using Flesch Reading Ease Score (FRES), Flesch Kincaid Grade Level (FKGL), Gunning Frequency of Gobbledygook (GFOG), and Simple Measure of Gobbledygook (SMOG). RESULTS: Thirty-one documents were evaluated. FRES scores ranged from 29.3 to 67.8 (possible range = 0 to 100), and averaged 50.5. FKGL ranged from 6.9 to 14.9 (possible range = 3 to 12), and averaged 10.4. SMOG scores ranged from 11.8 to 14.5 (possible range = 3 to 19), and averaged 13.0. GFOG scores ranged from 10.6 to 18.0 (possible range = 3 to 19), and averaged 13.5. CONCLUSIONS: Readability scores for online thyroid surgery materials are higher (i.e., more difficult) than the recommended levels. However, readability is only one aspect of comprehension. Written information should be designed with that fact in mind.

Readability assessment of internet-based patient education materials related to facial fractures.

OBJECTIVE/HYPOTHESIS: Various professional societies, clinical practices, hospitals, and health care-related Web sites provide Internet-based patient education material (IPEMs) to the general public. However, this information may be written above the 6th-grade reading level recommended by the US Department of Health and Human Services. The purpose of this study is to assess the readability of facial fracture (FF)-related IPEMs and compare readability levels of IPEMs provided by four sources: professional societies, clinical practices, hospitals, and miscellaneous sources. STUDY DESIGN: Analysis of IPEMs on FFs available on Google.com. METHODS: The readability of 41 FF-related IPEMs was assessed with four readability indices: Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (Gunning FOG). Averages were evaluated against national recommendations and between each source using analysis of variance and t tests. RESULTS: Only 4.9% of IPEMs were written at or below the 6th-grade reading level, based on FKGL. The mean readability scores were: FRES 54.10, FKGL 9.89, SMOG 12.73, and Gunning FOG 12.98, translating into FF-related IPEMs being written at a "difficult" writing level, which is above the level of reading understanding of the average American adult. CONCLUSIONS: IPEMs related to FFs are written above the recommended 6th-grade reading level. Consequently, this information would be difficult to understand by the average US patient.

Readability assessment of Internet-based patient education materials related to endoscopic sinus surgery.

OBJECTIVES/HYPOTHESIS: Numerous professional societies, clinical practices, and hospitals provide Internet-based patient education materials (PEMs) to the general public, but not all of this information is written at a reading level appropriate for the average patient. The National Institutes of Health and the US Department of Health and Human Services recommend that PEMs be written at or below the sixth-grade level. Our purpose was to assess the readability of endoscopic sinus surgery (ESS)-related PEMs available on the Internet and compare readability levels of PEMs provided by three sources: professional societies, clinical practices, and hospitals. STUDY DESIGN: A descriptive and correlational design was used for this study. METHODS: The readability of 31 ESS-related PEMs was assessed with four different readability indices: Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (Gunning FOG). Averages were evaluated against national recommendations and between each source using analysis of variance and t tests. RESULTS: The majority of PEMs (96.8%) were written above the recommended sixth-grade reading level, based on FKGL (P < .001). Only one article (3.2%) had an FKGL at or below the sixth-grade level. The mean readability values were: FRES 47.1 ± 13.4, FKGL 10.7 ± 2.4, SMOG 13.7 ± 1.6, and Gunning FOG 12.4 ± 2.7. CONCLUSIONS: Current Internet-based PEMs related to ESS, regardless of source type, were written well above the recommended sixth-grade level. Materials from the hospitals/university-affiliated websites had lower readability scores, but were still above recommended levels. Web-based PEMs pertaining to ESS should be written with the average patient in mind.
