#1
Christopher G Myers, Omar Yusef Kudsi, Amir A Ghaferi
: In response to technological advances and growing dispersion of surgical practice around the globe, social media platforms have emerged in recent years as channels for surgeons to share experiences, ask questions, and learn from one another. To better understand surgeons' engagement with these platforms, we analyzed data from a closed-membership Facebook group for robotic surgeons. Our analysis revealed that surgeons posted more frequently on midweek days, and further that text posts received significantly more comments, and significantly fewer "likes," than posts containing links, photos, or videos...

BACKGROUND: Bariatric surgery is a safe and effective treatment for clinically severe obesity, but inequity in male and female utilization is well recognized. Approximately 20% of patients undergoing bariatric surgery are male. This paper aims to describe differences in outcomes by gender and to understand the physiologic and psychological differences that may explain this gender gap. METHODS: We examined 61,708 patients from the Michigan Bariatric Surgery Collaborative (MBSC) undergoing primary bariatric surgery between 2006 and 2016...

OBJECTIVE: To describe hospital-level variation in roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) in Michigan. BACKGROUND: Bariatric surgery is an increasingly prevalent elective surgical procedure that will likely be considered for future bundled payment programs, both public and private. Past research in the Medicare population found that the index hospitalization is responsible for the majority of payment variation among hospitals. However, this research largely excluded SG, now the most commonly performed bariatric surgery procedure nationally...

Importance: Achieving a body mass index (BMI, calculated as weight in kilograms divided by height in meters squared) of less than 30 is an important goal of bariatric surgery, given the increased risk for weight-related morbidity and mortality with a BMI above this threshold. Objective: To identify predictors for achieving a BMI of less than 30 after bariatric surgery. Design, Setting, and Participants: This retrospective study used data from the Michigan Bariatric Surgery Collaborative, a statewide quality improvement collaborative that uses a prospectively gathered clinical data registry...

INTRODUCTION: Preoperative patient screening is a major contributor to the remarkable safety of bariatric surgery. Smoking status is a modifiable patient risk factor, and smoking cessation is associated with improved outcomes in surgical patients. However, the length of smoking cessation necessary to optimize bariatric surgery patient outcomes is not yet defined. We sought to explore the relationship between patient-reported smoking status and short-term bariatric surgery outcomes. METHODS: Using prospectively collected data from the MBSC registry, we evaluated the effects of patient-reported length of tobacco abstinence on 30-day surgical outcomes...

BACKGROUND: Video assessment is an emerging tool for understanding variation in surgical technique. METHODS: Representative videos of laparoscopic sleeve gastrectomy (LSG) were voluntarily submitted by 20 surgeons who participated in a statewide quality improvement collaborative. The amount of time required to complete the salient steps of the operation was measured and variations in the tasks performed during each step were captured. RESULTS: Twenty-two videos of LSG were submitted and 11 videos included concurrent hiatal hernia repair...

BACKGROUND: The Hospital Readmissions Reduction Program reduces payments to hospitals with excess readmissions for three common medical conditions and recently extended its readmission program to surgical patients. We sought to investigate readmission intensity as measured by readmission cost for high-risk surgeries and examine predictors of higher readmission costs. MATERIALS AND METHODS: We used the Healthcare Cost and Utilization Project's State Inpatient Database to perform a retrospective cohort study of patients undergoing major chest (aortic valve replacement, coronary artery bypass grafting, lung resection) and major abdominal (abdominal aortic aneurysm repair [open approach], cystectomy, esophagectomy, pancreatectomy) surgery in 2009 and 2010...

OBJECTIVE: This study sought to explore the relationship of bariatric surgeon age and patient outcomes. BACKGROUND: Regulators, policy makers, and patient advocacy groups have recently been pushing to establish clear guidelines for physician retirement in the United States. Although it is often assumed that increasing physician age leads to worse patient outcomes, the relationship is lacking robust evidence, and is still unclear. METHODS: We conducted a study analyzing all bariatric surgeons in Michigan who participated in a statewide collaborative quality improvement program (n = 71) who performed primary laparoscopic Roux-en-Y Gastric Bypass, or sleeve gastrectomy operations, and data on their patients (n = 60430) over the past 10 years...

Importance: In the United States, reports about perioperative complications associated with bariatric surgery led to the establishment of accreditation criteria for bariatric centers of excellence and many bariatric centers obtaining accreditation. Currently, most bariatric procedures occur at these centers, but to what extent they uniformly provide high-quality care remains unknown. Objective: To describe the variation in surgical outcomes across bariatric centers of excellence and the geographic availability of high-quality centers...

Predictors of weight loss responses are not well-defined. We hypothesized that adipose tissue phenotypic features related to remodeling would be associated with bariatric surgery weight loss responses. Visceral and subcutaneous adipose tissues collected from patients during bariatric surgery were studied with flow cytometry, immunohistochemistry, and QRTPCR, and results correlated with weight loss outcomes. Age, male sex, and a diagnosis of type 2 diabetes were associated with less weight loss. Adipocyte size was increased and preadipocyte frequency was decreased in visceral adipose tissue from diabetic subjects...

Context: The role of the extracellular matrix (ECM) in regulating adipocyte metabolism in the context of metabolic disease is poorly defined. Objective: The objective of this study was to define the metabolic phenotype of adipocytes associated with human diabetes (DM) and the role of the ECM in regulating adipocyte metabolism. Design: Adipose tissues from obese patients were studied in standard 2-dimensional (2D) cell culture and an in vitro model of decellularized adipose tissue ECM repopulated with human adipocytes, and results were correlated with DM status...

OBJECTIVE: The aim of this study was to explore the efficacy of current bariatric perioperative measures at reducing emergency department (ED) visits following bariatric surgery in the state of Michigan. SUMMARY OF BACKGROUND DATA: Many ED visits following bariatric surgery do not result in readmission and may be preventable. Little research exists evaluating the efficacy of perioperative measures aimed at reducing ED visits in this population. Therefore, understanding the driving factors behind these preventable ED visits may be a fruitful approach to prevention...

BACKGROUND: Several patient and surgical characteristics have been identified as risk factors for readmission after bariatric surgery, but there is a paucity of information on how organizational factors influence this metric. OBJECTIVE: To evaluate the association between readmissions and several organizational factors, including compliance with best practices to reduce unplanned hospital visits, major complication rates, and the emergency department-sourced readmission (EDSR) rate...

OBJECTIVE: To evaluate the extent to which patient-reported outcomes (PROs) (eg, health-related quality of life) are distinct from clinical outcomes following bariatric surgery. BACKGROUND: Hospital quality measurement often focuses on traditional clinical outcomes (eg, complications). However, PROs may provide a unique perspective regarding performance, particularly for common, low-risk procedures. METHODS: We used data from 11,420 patients who underwent bariatric surgery (2008-2012) from the Michigan Bariatric Surgery Collaborative (39 hospitals)...
