Barriers to Participation in a Structured Quality Improvement Initiative to Reduce Avoidable Emergency Department Visits-A Qualitative Study.

INTRODUCTION: Barriers to quality improvement (QI) initiatives in multi-institutional hospital settings are understudied. Here we describe a qualitative investigation of factors negatively affecting a QI initiative focused on reducing avoidable emergency department (ED) visits after bariatric surgery across 17 hospitals. Our goal was to explore participant perspectives and identify themes describing why the program was not effectively implemented or why the program may have been ineffective when correctly implemented. METHODS: We performed semistructured group interviews with 17 sites (42 interviews) participating in a statewide bariatric QI program. We used descriptive content analysis to identify challenges, facilitators, and barriers to implementation of the QI program. All analyses were conducted using MAXQDA software. RESULTS: Results revealed barriers across hospitals related to four themes: buy-in, provider accessibility, resources at participating hospitals, and patient barriers to care. In particular, the initiative faced difficulty if it was not well-matched to the factors driving increasing ED visits at a particular site, such as lack of patient access to outpatient or primary care. Additional challenges occurred if the initiative was not adapted and customized to the working systems in place at each site, involving employees, surgeons, support staff, and leadership. CONCLUSIONS: Overall, findings can direct future focused efforts aimed at site-specific interventions to reduce unnecessary postoperative ED visits. Results demonstrated a need for a nuanced approach that can be adapted based on facility needs and resources.

From Alpha to Omicron and Beyond: Associations Between SARS-CoV-2 Variants and Surgical Outcomes.

INTRODUCTION: The COVID-19 pandemic has significantly influenced surgical practices, with SARS-CoV-2 variants presenting unique pathologic profiles and potential impacts on perioperative outcomes. This study explores associations between Alpha, Delta, and Omicron variants of SARS-CoV-2 and surgical outcomes. METHODS: We conducted a retrospective analysis using the National COVID Cohort Collaborative database, which included patients who underwent selected major inpatient surgeries within eight weeks post-SARS-CoV-2 infection from January 2020 to April 2023. The viral variant was determined by the predominant strain at the time of the patient's infection. Multivariable logistic regression models explored the association between viral variants, COVID-19 severity, and 30-d major morbidity or mortality. RESULTS: The study included 10,617 surgical patients with preoperative COVID-19, infected by the Alpha (4456), Delta (1539), and Omicron (4622) variants. Patients infected with Omicron had the highest vaccination rates, most mild disease, and lowest 30-d morbidity and mortality rates. Multivariable logistic regression demonstrated that Omicron was linked to a reduced likelihood of adverse outcomes compared to Alpha, while Delta showed odds comparable to Alpha. Inclusion of COVID-19 severity in the model rendered the odds of major morbidity or mortality equal across all three variants. CONCLUSIONS: Our study examines the associations between the clinical and pathological characteristics of SARS-CoV-2 variants and surgical outcomes. As novel SARS-CoV-2 variants emerge, this research supports COVID-19-related surgical policy that assesses the severity of disease to estimate surgical outcomes.

Conversion of sleeve gastrectomy to Roux-en-Y gastric bypass: impact on reflux and weight loss.

BACKGROUND: Sleeve gastrectomy (SG) is the most commonly performed weight loss operation, and its 2 most common complications are postoperative reflux and weight recurrence. There is limited evidence to guide decision-making in treating these conditions. OBJECTIVES: To determine the efficacy of conversion of SG to Roux-en-Y gastric bypass (RYGB) for GERD management and weight loss. SETTING: Forty-one hospitals in Michigan. METHODS: We conducted a retrospective cohort study examining patients who underwent conversion of SG to RYGB from 2014 to 2022. The primary outcomes were changes in GERD-HRQL scores, anti-reflux medication use, and weight from baseline to 1 year after conversion. Secondary outcomes included 30-day postoperative complications and resource utilization. RESULTS: Among 2133 patients undergoing conversion, 279 (13%) patients had baseline and 1-year GERD-HRQL survey data and anti-reflux medication data. GERD-HRQL scores decreased significantly from 24.6 to 6.6 (P < .01). Among these, 207 patients (74%) required anti-reflux medication at baseline, with only 76 patients (27%) requiring anti-reflux medication at 1 year postoperatively (P < .01). Of the 380 patients (18%) with weight loss data, mean weight decreased by 68.4lbs, with a 24.3% decline in total body weight and 51.5% decline in excess body weight. In terms of 30-day complications, 308 (14%) patients experienced any complication and 89 (4%) experienced a serious complication, but there were no leaks, perforations, or deaths. Three-hundred and fifty-five (17%) patients presented to the emergency department and 64 (3%) patients underwent reoperation. CONCLUSIONS: This study represents the largest reported experience with conversion from SG to RYGB. We found that conversion to RYGB is associated with significant improvement in GERD symptoms, reduction in anti-reflux medication use, and significant weight loss and is therefore an effective treatment for GERD and weight regain after SG. However, the risks and benefits of conversion surgery should be carefully considered, especially in patients with significant comorbidity burden.
