The impact of COVID-19 pandemic on patient selection and access to care, approach type, and postoperative outcomes in bariatric surgery.

BACKGROUND: The COVID-19 pandemic had affected the health systems across the world since early 2020 with a concern about access to medical care during the first wave of COVID-19 pandemic. OBJECTIVES: The objective of this study was to examine how the COVID-19 pandemic influenced patient selection, approach type, and postoperative outcomes in elective bariatric surgery. SETTING: United States. METHODS: Data from the MBSAQIP database for the years 2016-2020 were queried. Wilcoxon rank-sum test and Fisher's exact test were employed for continuous and categorical variables, respectively. Postoperative outcomes within 30 days were assessed separately and based on the Clavien-Dindo (CD) classification of III-V. χ2 test and logistic regression were used to compare outcomes between procedure and approach types, as well as surgical operation periods. RESULTS: A total of 741,620 patients underwent robotic and laparoscopic sleeve gastrectomy and Roux-en-Y gastric-bypass. The cases performed in 2020 exhibited lower comorbidities and postoperative complications compared to prepandemic years, regardless of the approach type. Notably, the proportion of White patients decreased during the pandemic, while there was an increase in the number of African American and Hispanic patients who had bariatric surgery. CONCLUSIONS: Patients who underwent bariatric surgery during the COVID-19 pandemic appeared to be healthier with fewer comorbidities and experienced fewer adverse postoperative outcomes compared to those who had surgery prior to the pandemic. This study highlights the limited access to bariatric surgery for high-risk patients during the pandemic.

The impact of gender, race, and ethnicity on bariatric surgery outcomes.

BACKGROUND: The rates of postoperative complications can vary among specific patient populations. OBJECTIVES: The aim of this study is to examine how gender, race, and ethnicity can affect short-term postoperative complications in bariatric surgery patients. SETTING: United States. METHODS: Patients who underwent bariatric surgery between the years 2016 and 2021 were included and stratified based on gender, race/ethnicity, and procedure type. The 30-day outcomes were assessed using Clavien-Dindo (CD) classification of III-V. Wilcoxon rank-sum test was performed to compare continuous variables among groups and Chi-squared test for categorical variables. Logistic regression was performed to examine the effects of gender, race/ethnicity on CD classification ≥ III complications by the procedure type. RESULTS: A total of 975,642 bariatric surgery patients were included. Descriptive univariate analysis showed that CD ≥ III complications were higher among non-Hispanic blacks (NHB) and lowest in Hispanic patients, regardless of their gender, except in the duodenal switch DS group, where non-Hispanic whites (NHW) had the lowest complication rate. There was no difference between male and female patients with regards to postoperative complications, except in the sleeve gastrectomy (SG) group, where NHW males had more complications than NHW females. Sleeve gastrectomy showed the lowest complication rates followed by gastric bypass and DS in all groups. In multivariate logistic regression model, for both females and males NHBs had higher odds of postoperative complications compared to NHWs in sleeve gastrectomy (Female aOR:1.31, 95% CI: [1.23-1.40]; Male aOR:1.24, 95% CI: [1.08-1.43], P < .001) and gastric bypass (Female aOR:1.24, 95% CI: [1.16-1.33]; Male aOR:1.25, 95% CI: [1.06-1.48], P < .01). CONCLUSIONS: Non-Hispanic Black patients are at a higher rate of developing CD ≥ III complications compared to non-Hispanic Whites after bariatric surgery. The male gender was not a significant risk factor for serious postoperative complications. Among the different types of bariatric procedures, sleeve gastrectomy has the lowest rates of severe complications, followed by gastric bypass and duodenal switch. These results highlight the significance of considering gender, race, ethnicity, and procedure type during preoperative evaluation, surgical planning, and postoperative care.

First Assistant In Bariatric Surgery: A Comparison Between Laparoscopic And Robotic Approaches: A 4-Year Analysis of the MBSAQIP Database (2016-2019).

PURPOSE: The first assistant (FA) plays an important role in the operating room for bariatric surgery. The aim of this study was to examine the relationship between the type of FA and operative time (OT) and postoperative outcomes comparing robotic and laparoscopic approaches in bariatric surgery. METHODS AND MATERIALS: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data for 2016-2019 was queried. Log-normal regression was performed to evaluate the association of FAs and OT variations within and between groups. We used logistic regression to examine the relationship between the type of FA and 30-day outcomes across all procedures and approaches. RESULTS: A total of 691,789 patients who underwent robotic (R), and laparoscopic (L) sleeve gastrectomy (SG), Roux-en-Y gastric-bypass (RYGB), and duodenal switch (DS) were included. The percentage variation of OT was higher in the laparoscopic group (L-SG: 8.18%, L-RYGB: 9.88%, and L-DS: 15.00%) compared to the robotic group (R-SG: 2.43%, R-RYGB: 5.76%, and R-DS: 0.80%). There was not a significant difference in 30-day outcomes between laparoscopic and robotic approaches for the same procedures. CONCLUSIONS: The FA was associated with a decreased variability in OT in the robotic cohort compared to the laparoscopic group with no significant difference in complication rates. These results suggest that the robotic approach may decrease the need for skilled FAs in bariatric procedures.

Robotic Bariatric Surgery in Older Adults, Is It Safer Than the Laparoscopic Approach? A 7-Year Analysis of Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Database.

BACKGROUND: Utilization of the robotic platform in bariatric surgery has increased over the past several years. The population of older adults who benefit from bariatric surgery is also growing. This study evaluated the safety of robotic-assisted bariatric surgery in older adults using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Database. METHODS: Adults who underwent gastric bypass or sleeve gastrectomy and were ≥ 65 years old between the years 2015 and 2021 were included. The 30-day outcomes were assessed and stratified based on Clavien-Dindo (CD) classification of III-V. Univariable and multivariable logistic regressions were performed to identify predictors of CD ≥ III complications. RESULTS: A total of 62,973 bariatric surgery patients were included. Most of the patients (90%) underwent laparoscopic surgery, and the remainder (10%) underwent robotic surgery. Robotic sleeve gastrectomy (R-SG) was associated with lower odds of developing CD ≥ III complications compared to three other procedures (adjusted odds ratio (aOR), 0.741; confidence interval (CI), 0.584-0.941; p 0.014). CONCLUSIONS: Bariatric surgery using a robotic approach is considered safe for older patients. Robotic sleeve gastrectomy (R-SG) has the lowest morbidity and mortality rates compared to laparoscopic sleeve gastrectomy (L-SG), laparoscopic Roux-en-Y gastric bypass (L-RYGB), and robotic Roux-en-Y gastric bypass (R-RYGB). The findings of this study can help surgeons and their elderly patients to make informed decisions regarding the safety of different bariatric surgical approaches.

A systematic review of robotic surgery curricula using a contemporary educational framework.

BACKGROUND: There has been a rising trend in robotic surgery. Thus, there is demand for a robotic surgery curriculum (RSC) for training surgical trainees and practicing surgeons. There are limited data available about current curricular designs and the extent to which they have incorporated educational frameworks. Our aim was to study the existing robotic surgery curricula using Kern's 6-step approach in curriculum development. METHODS: A systematic review was conducted using PubMed, PubMed Central, Cochrane, Embase, and Scopus (we searched studies from 2001 to 2021). PRISMA Guidelines was used to guide the search. Curriculum designed for general surgery and its subspecialties were included. Urology and gynecology were excluded. The articles were reviewed by five reviewers. RESULTS: Our review yielded 71 articles, including 39 curricula at 9 different settings. Using Kern's framework, we demonstrated that the majority of robotic surgery curricula contained all the elements of Kern's curricular design. However, there were significant deficiencies in important aspects of these curricula i.e., implementation, the quality of assessment tools for measurement of performance and evaluation of the educational value of these interventions. Most institutions used commercial virtual reality simulators (VRS) as the main component of their RSC and 23% of curricula only used VRS. CONCLUSIONS: Although majority of these studies contained all the elements of Kern's framework, there are critical deficiencies in the components of existing curricula. Future curricula should be designed using established educational frameworks to improve the quality of robotic surgery training.

A light touch intervention with a heavy lift - gender, space and risk in a global vaccination programme.

Frontline workers (FLWs) in the Global Polio Eradication Initiative go door-to-door delivering polio vaccine to children. They have played a pivotal role in eliminating wild polio from most countries on earth; at the same time, they face significant bodily risk. STRIPE, an international consortium, conducted a mixed-methods study exploring the knowledge and experiences of polio staff in seven countries (Afghanistan, Bangladesh, Democratic Republic of Congo, Ethiopia, India, Indonesia and Nigeria). We surveyed 826 polio FLWs and conducted semi-structured interviews with 22 of them. We used a body work framework to guide analysis. Polio workers perform a different kind of body work than many other FLWs. Delivering a few drops of oral vaccine takes a light touch, but gendered spaces can make the work physically dangerous. Polio's FLWs must bend or break gendered space norms as they move from house-to-house. Navigating male spaces carries risk for women, including lethal risk, particularly in conflict settings. Workers manoeuvre between skeptical community members and the demands of supervisors which generates emotional labour. Providing FLWs with more power to make operational decisions and providing them with robust teams and remuneration would improve the likelihood that they could act to improve their working conditions.

Conflict, community, and collaboration: shared implementation barriers and strategies in two polio endemic countries.

BACKGROUND: Afghanistan and Nigeria are two of the three remaining polio endemic countries. While these two countries have unique sociocultural characteristics, they share major polio risk factors. This paper describes the countries' shared contexts and highlights important lessons on implementing polio eradication activities among hard-to-reach populations relevant for future global health programs. METHODS: A grey literature review of the Global Polio Eradication Initiative (GPEI) followed by an online survey was conducted in both countries. The survey was targeted to individuals who have been involved continuously in polio eradication activities for 12 months or more since 1988. A sub-set of respondents from the survey was recruited for key-informant interviews (KII). The survey and KIIs were conducted between September 2018-April 2019. A cross-case comparison analysis was conducted to describe shared implementation challenges, strategies, and unintended consequences of polio eradication activities across these contexts. RESULTS: Five hundred thirteen and nine hundred twenty-one surveys were completed in Afghanistan and Nigeria respectively; 28 KIIs were conducted in Afghanistan and 29 in Nigeria. Major polio eradication activities in both countries include house-to-house campaigns, cross-border stations, outreach to mobile populations, and surveillance. Common barriers to these activities in both countries include civil unrest and conflict; competing political agendas; and vaccine refusal, fatigue, and mistrust, all of which are all bases for describing hard-to-reach populations. Both countries employed strategies to engage community leadership, political and religious groups through advocacy visits, and recruited community members to participate in program activities to address misconceptions and distrust. Recruitment of female workers has been necessary for accessing women and children in conservative communities. Synergy with other health programs has been valuable; health workers have improved knowledge of the communities they serve which is applicable to other initiatives. CONCLUSIONS: The power of community engagement at all levels (from leadership to membership) cannot be overstated, particularly in countries facing civil unrest and insecurity. Workforce motivation, community fatigue and mistrust, political priorities, and conflict are intricately interrelated. Community needs should be holistically assessed and addressed;programs must invest in the needs of health workers who engage in these long-term health programs, particularly in unsafe areas, to alleviate demotivation and fatigue.

Evaluating the process of partnership and research in global health: reflections from the STRIPE project.

BACKGROUND: Thoughtful and equitable engagement with international partners is key to successful research. STRIPE, a consortium of 8 academic and research institutions across the globe whose objective is to map, synthesize, and disseminate lessons learned from polio eradication, conducted a process evaluation of this partnership during the project's first year which focused on knowledge mapping activities. METHODS: The STRIPE consortium is led by Johns Hopkins University (JHU) in partnership with 6 universities and 1 research consultancy organization in polio free, at-risk, and endemic countries. In December 2018 JHU team members submitted written reflections on their experiences (n = 9). We held calls with each consortium member to solicit additional feedback (n = 7). To establish the partnership evaluation criteria we conducted preliminary analyses based on Blackstock's framework evaluating participatory research. In April 2019, an in-person consortium meeting was held; one member from each institution was asked to join a process evaluation working group. This group reviewed the preliminary criteria, adding, subtracting, and combining as needed; the final evaluation criteria were applied to STRIPE's research process and partnership and illustrative examples were provided. RESULTS: Twelve evaluation criteria were defined and applied by each member of the consortium to their experience in the project. These included access to resources, expectation setting, organizational context, external context, quality of information, relationship building, transparency, motivation, scheduling, adaptation, communication and engagement, and capacity building. For each criteria members of the working group reflected on general and context-specific challenges and potential strategies to overcome them. Teams suggested providing more time for recruitment, training, reflection, pre-testing. and financing to alleviate resource constraints. Given the large scope of the project, competing priorities, and shifting demands the working group also suggested a minimum of one full-time project coordinator in each setting to manage resources. CONCLUSION: Successful management of multi-country, multicentered implementation research requires comprehensive communication tools (which to our knowledge do not exist yet or are not readily available), expectation setting, and institutional support. Capacity building activities that address human resource needs for both individuals and their institutions should be incorporated into early project planning.
