Abstract
Patient education materials (PEMs) serve as a foundation for educating patients and families across all surgical fields but are often not understandable. The National Institute of Health (NIH) recommends that PEMs be written at a grade 6-7 reading level; however, most current materials exceed that measure.3 Lack of understandable and appropriate surgical PEMs compounds the difficulties that low health literacy patients face with resultant poor surgical outcomes.2,3 The challenge for surgeons is to adequately educate patients pre-operatively and post-operatively on the complexities of surgery. Another challenge is to compact decades of education and training into an easy-to-understand medium for patients. To address this challenge, many physicians have utilized visual aids to improve PEM efficacy. While visual aids are a critical piece of education materials, they must be designed intentionally to be effective. The most important consideration is that the PEM communicates the information clearly to users. With this in mind, we created a framework for productive utilization of visual aids by integrating the C.A.R.P. graphic design technique into an existing surgical PEM to enhance communication and understandability.

Abstract
BACKGROUND Racial/ethnic disparities in outcomes exist for patients with inflammatory bowel disease (IBD) undergoing surgery. The underlying mechanism(s) remain unclear and patient perspectives are needed. We therefore aimed to characterize the surgical experience for Black and White IBD patients using qualitative methods. METHODS Patients with IBD who had undergone surgery were recruited to same-race qualitative interviews. Semi-structured interviews explored barriers and facilitators to a positive or negative surgical experience. Transcripts were analyzed with NVivo 12 software. RESULTS Six focus groups were conducted that included 10 Black and 17 White IBD participants. The mean age was 44.8 years (SD 13.2), 52% were male and 65% had Crohn's disease. Four themes emerged that most defined the surgical experience: the impact of the IBD diagnosis, the quality of provided information, disease management and the surgery itself. Within these themes, barriers to a positive surgical experience included inadequate personal knowledge of IBD, ineffective written and verbal communication, lack of a support system and complications after surgery. Both groups reported that information was provided inconsistently which led to unclear expectations of surgical outcomes. CONCLUSIONS Black and White patients with IBD have varied surgical experiences but all stressed the importance of accurate, trustworthy and understandable health information. These findings highlight the value of providing health literacy-sensitive care in surgery.

Abstract
Background Telemedicine use has increased significantly during the COVID-19 pandemic. It remains unclear if its rapid growth exacerbates disparities in healthcare access. We aimed to characterize telemedicine use among a large oncology population in the Deep South during the COVID-19 pandemic. Materials and Methods A retrospective cohort study was performed at the only National Cancer Institute designated-cancer center in Alabama March 2020 to December 2020. With a diverse (26.5% Black, 61% rural) population, this southeastern demographic uniquely reflects historically vulnerable populations. All non-procedural visits at the cancer center from March to December 2020 were included in this study excluding those with a department that had fewer than 100 visits during this time period. Patient and clinic level characteristics were analyzed using t-test and Chi-square to compare characteristics between visit types (in-person versus telemedicine, and video versus audio within telemedicine). Generalized estimating equations were used to identify independent factors associated with telemedicine use and type of telemedicine use. Results There were 50 519 visits and most were in-person (81.3%). Among telemedicine visits, most were phone based (58.3%). Black race and male sex predicted in-person visits. Telemedicine visits were less likely to have video among patients who were Black, older, male, publicly insured, and from lower income areas. Conclusions Telemedicine use, specifically with video, is significantly lower among historically vulnerable populations. Understanding barriers to telemedicine use and preferred modalities of communication among different populations will help inform insurance reimbursement and interventions at different socioecological levels to ensure the continued evolution of telemedicine is equitable.

Abstract
Objectives COVID-19 has caused significant surgical delays as institutions minimize patient exposure to hospital settings and utilization of health care resources. We aimed to assess changes in surgical case mix and outcomes due to restructuring during the pandemic. Methods Patients undergoing surgery at a single tertiary care institution in the Deep South were identified using institutional ACS-NSQIP data. Primary outcome was case mix. Secondary outcomes were post-operative complications. Chi-square, ANOVA, logistic regression, and linear regression were used to compare the control (pre-COVID, Mar 2018-Mar 2020) and case (during COVID, Mar 2020-Mar 2021) groups. Results Overall, there were 6912 patients (control: 4,800 and case: 2112). Patients were 70% white, 29% black, 60% female, and 39% privately insured. Mean BMI was 30.2 (SD = 7.7) with mean age of 58.3 years (SD = 14.8). Most surgeries were with general surgery (48%), inpatient (68%), and elective (83%). On multivariable logistic regression, patients undergoing surgery during the pandemic were more likely to be male (OR: 1.14) and in SIRS (OR: 2.07) or sepsis (OR: 2.28) at the time of surgery. Patients were less likely to have dyspnea with moderate exertion (OR: .75) and were less dependent on others (partially dependent OR: .49 and totally dependent OR: .15). Surgeries were more likely to be outpatient (OR: 1.15) and with neurosurgery (OR: 1.19). On bivariate analysis, there were no differences in post-operative outcomes. Conclusion Surgeries during the COVID-19 pandemic were more often outpatient without differences in post-operative outcomes. Additional analysis is needed to determine the impact of duration of operative delay on surgical outcomes with restructuring focusing more on outpatient surgeries.

Abstract
BACKGROUND Racial disparities in surgical outcomes exist for Black patients with IBD compared to White patients. However, previous studies fail to include other racial/ethnic populations. We hypothesized these disparities exist for Hispanic and Asian patients. METHODS This is a retrospective cohort study of patients undergoing surgery for IBD using the American College of Surgeons National Surgical Quality Improvement Program (ACS- NSQIP) database (2005-2017). Bivariate comparisons and adjusted multivariable regressions were performed to evaluate associations between race and outcomes. RESULTS Of 23,901 patients with IBD, the racial/ethnic makeup were: 88.7% White, 7.6% Black, 2.4% Hispanic and 1.4% Asian. Overall mean LOS was 8 days (SD 8.2) and significantly varied between groups (8d for White, 10d for Black, 8.5d for Hispanic, and 11.1d for Asian; p < 0.001). Hispanic patients had the highest odds of readmission (OR: 1.4; 95% CI 1.1-1.8). Black patients had increased odds of renal insufficiency (OR: 1.8; 95% CI 1.1-2.9), bleeding requiring transfusions (OR: 1.7; 95% CI 1.4-1.9), and sepsis (OR: 1.7; 95% CI 1.4-2.02) compared to White patients. CONCLUSIONS Racial disparities exist among IBD patients undergoing surgery. Black, Hispanic and Asian IBD patients experience major disparities in post-operative complications, readmissions and LOS, respectively, when compared to White patients with IBD. Future research is needed to better understand the mechanisms of these disparities including evaluation of social determinants of health.

Abstract
Background: Low health literacy is associated with poor health outcomes in many chronic diseases and may have an important role in determining surgical outcomes. This study aims to comprehensively review the current state of science on adult health literacy in surgery and to identify knowledge gaps for future research. Methods: Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic search was conducted to identify all studies from January 2002 through May 2018 that used validated instruments to assess health literacy among adult patients undergoing surgery. Studies were assessed for quality using the Newcastle-Ottawa scale and evaluated on findings by their focus on identifying health literacy levels, understanding associations with surgical outcomes, and/or developing interventions to address low health literacy. Key Results: There were 51 studies on health literacy with data from 22,139 patients included in this review. Low health literacy was present in more than one-third of surgical patients (34%, interquartile range 16%–50%). The most commonly used validated instrument for assessment of health literacy in the surgical population was the Newest Vital Sign. Most studies were focused on identifying the prevalence of low health literacy within a surgery population (84%, n = 43). Few studies focused on understanding the association of health literacy to surgical outcomes (12%, n = 6) and even fewer studies developed interventions to address health literacy (4%, n = 2). Discussion: Low health literacy is common among surgical patients. Important opportunities exist to better understand the role of health literacy in determining surgical outcomes and to develop more health literacy-sensitive models of surgical care. [HLRP: Health Literacy Research and Practice. 2020;4(1):e45–e65.] Plain Language Summary: Health literacy has not been well-studied in surgery but likely plays an important role. In this article, we reviewed all current research on health literacy in surgery to help us understand where we are at and where we need to go. We found that low health literacy is common and we need more ways to address it in surgery.

Abstract
BACKGROUND Low health literacy is common in general populations, but its prevalence in the inflammatory bowel disease (IBD) population is unclear. The objective of this study was to assess the prevalence of low health literacy in a diverse IBD population and to identify risk factors for low health literacy. METHODS Adult patients with IBD at a single institution from November 2017 to May 2018 were assessed for health literacy using the Newest Vital Sign (NVS). Demographic and socioeconomic data were also collected. Primary outcome was the prevalence of low health literacy. Secondary outcomes were length-of-stay (LOS) and 30-day readmissions after surgical encounters. Bivariate comparisons and multivariable regression were used for analyses. RESULTS Of 175 IBD patients, 59% were women, 23% were African Americans, 91% had Crohn disease, and mean age was 46 years (SD = 16.7). The overall prevalence of low health literacy was 24%. Compared to white IBD patients, African Americans had significantly higher prevalence of low health literacy (47.5% vs 17.0%, P < 0.05). On multivariable analysis, low health literacy was associated with older age and African American race (P < 0.05). Of 83 IBD patients undergoing abdominal surgery, mean postoperative LOS was 5.5 days and readmission rate was 28.9%. There was no significant difference between LOS and readmissions rates by health literacy levels. CONCLUSIONS Low health literacy is present in IBD populations and more common among older African Americans. Opportunities exist for providing more health literacy-sensitive care in IBD to address disparities and to benefit those with low health literacy.

Abstract
INTRODUCTION Racial/ethnic disparities in surgical outcomes exist. Enhanced recovery programs (ERPs) have reduced some racial/ethnic disparities, but it remains unclear if disparities in experiences are also reduced. The purpose of this study was to use qualitative methods to better understand the surgical experience for African-American and Caucasian patients in the setting of an ERP. METHODS Using purposeful sampling at a minority-serving institution, we recruited African-American and Caucasian patients who had undergone colorectal surgery under an ERP to six focus groups. Participants identified barriers and facilitators to a positive, or negative, surgical experience. Audio recordings were transcribed and analyzed using an indicative thematic approach with NVivo 10 software (QSR International). RESULTS Forty-three patients (15 African-Americans and 28 Caucasians) participated in six focus groups. Six themes were identified by patients to be important in surgery: 1) knowledge about colorectal surgery, 2) obtaining information, 3) quality of information, 4) setting expectations about surgery, 5) following preoperative and postoperative instructions, and 6) confidence in surgery outcomes. For both racial/ethnic groups, patients felt that more information could have been provided, information should be given at their level of understanding, and trust in the physician made them feel confident in a positive outcome. African-American patients described experiences of having incorrect or no expectations on surgical outcomes, being provided inconsistent information, and feeling misled. African-Americans also described following instructions from family members and valued the importance of diet and exercise in recovery. CONCLUSIONS African-American and Caucasian surgical patients have varied surgical experiences even under an ERP. All patients, however, valued the ability to obtain, process, and understand health information during the surgical process. These elements define "health literacy" and suggest the importance of providing health literacy-sensitive care in surgery.
