Generalized Pairwise Comparisons to Support Shared Decision-Making in the CODA Trial.

Importance: Shared decision-making (SDM) can be made difficult by the multifaceted nature of outcome assessment. A rigorous method for analyzing results from multiple outcomes is called generalized pairwise comparisons (GPC), which could assist in SDM.

Objective: To examine whether GPC can be useful in SDM by using individual-patient data from the Comparison of Outcomes of Antibiotic Drugs and Appendectomy (CODA) trial.

A Multicenter Assessment of the Accuracy of Claims Data in Appendicitis Research.

Objective: To investigate accuracy of ICD-9/10 billing codes in a multicenter cohort.

Summary Of Background Data: Health services research on appendicitis often relies on administrative databases. However, billing codes may misclassify disease severity, as we demonstrated previously in a single institution study.

Antibiotic treatment versus appendicectomy for acute appendicitis in adults: an individual patient data meta-analysis.

Background: Randomised controlled trials (RCTs) have found antibiotics to be a feasible and safe alternative to appendicectomy in adults with imaging-confirmed acute appendicitis. However, patient inclusion criteria and outcome definitions vary greatly between RCTs. We aimed to compare antibiotics with appendicectomy for the treatment of acute appendicitis using individual patient data and uniform outcome definitions.

Patient and Surgeon Attitudes Toward Opportunistic Salpingectomy During Nongynecological Surgeries for the Prevention of Ovarian Cancer: A Qualitative Study.

Background And Objectives: Opportunity salpingectomy (OS), or prophylactic removal of the fallopian tubes during an operation for another indication, is broadly accepted as a risk-reduction strategy for ovarian cancer during gynecological operations. However, OS during nongynecological abdominal surgery is rare in the United States. A better understanding of surgeon and patient attitudes and perceived barriers to OS during nongynecological surgeries may facilitate implementation in the United States.

Use and Outcomes of Dexamethasone in the Management of Malignant Small Bowel Obstruction.

Objective: To describe rates of dexamethasone use in the nonoperative management of malignant small bowel obstruction (mSBO) and their outcomes.

Background: mSBO is common in patients with advanced abdominal-pelvic cancers. Management includes prioritizing quality of life and avoiding surgical intervention when possible.

Similarities and Differences Between Pragmatic Trials and Hybrid Effectiveness-Implementation Trials.

Pragmatism in clinical trials is focused on increasing the generalizability of research findings for routine clinical care settings. Hybridism in clinical trials (i.e.

Operative vs Nonoperative Management of Acute Cholecystitis During the Different Trimesters of Pregnancy.

Importance: Acute cholecystitis (AC) management during pregnancy requires balancing the risk of pregnancy loss or preterm delivery (adverse pregnancy outcomes [APOs]) with or without surgery. Guidelines recommend cholecystectomy across trimesters; however, trimester-specific evidence on the risks of AC and its management is lacking.

Objective: To assess cholecystectomy frequency in pregnant people with AC, compare the rates of APOs in pregnant people with or without AC, and compare the rates of APOs in people with AC who did or did not undergo cholecystectomy.

Factors associated with recurrent appendicitis after successful treatment with antibiotics.

Background: As more patients with appendicitis are treated with antibiotics, factors associated with recurrence may help inform individualized prognostication and decision-making.

Methods: This cohort study, using data from the Comparison of Outcomes of Antibiotic Drugs and Appendectomy trial, examined patients treated with antibiotics who did not undergo appendicectomy in the first 30 days. Patients who had appendicectomy between 30 days and 1 year were compared with those who did not.

Factors associated with lung cancer risk factor documentation.

Objectives: To identify factors associated with the minimum necessary information to determine an individual’s eligibility for lung cancer screening (ie, sufficient risk factor documentation) and to characterize clinic-level variability in documentation.

Study Design: Cross-sectional observational study using electronic health record data from an academic health system in 2019.

Methods: We calculated the relative risk of sufficient lung cancer risk factor documentation by patient-, provider-, and system-level variables using Poisson regression models, clustering by clinic.

Diverticulitis is a population health problem: Lessons and gaps in strategies to implement and improve contemporary care.

The disease burden of diverticulitis is high across inpatient and outpatient settings, and the prevalence of diverticulitis has increased. Historically, patients with acute diverticulitis were admitted routinely for intravenous antibiotics and many had urgent surgery with colostomy or elective surgery after only a few episodes. Several recent studies have challenged the standards of how acute and recurrent diverticulitis are managed, and many clinical practice guidelines (CPGs) have pivoted to recommend outpatient management and individualized decisions about surgery.

Two decades of surgical randomized controlled trials: worldwide trends in volume and methodological quality.

Background: RCTs are essential in guiding clinical decision-making but are difficult to perform, especially in surgery. This review assessed the trend in volume and methodological quality of published surgical RCTs over two decades.

Methods: PubMed was searched systematically for surgical RCTs published in 1999, 2009, and 2019.

Trial Participation and Outcomes Among English-Speaking and Spanish-Speaking Patients With Appendicitis Randomized to Antibiotics: A Secondary Analysis of the CODA Randomized Clinical Trial.

Importance: Spanish-speaking participants are underrepresented in clinical trials, limiting study generalizability and contributing to ongoing health inequity. The Comparison of Outcomes of Antibiotic Drugs and Appendectomy (CODA) trial intentionally included Spanish-speaking participants.

Objective: To describe trial participation and compare clinical and patient-reported outcomes among Spanish-speaking and English-speaking participants with acute appendicitis randomized to antibiotics.

Development and Feasibility Testing of a Decision Aid for Acute Appendicitis.

Introduction: Patients with acute uncomplicated appendicitis will be increasingly asked to choose between surgery and antibiotic management. We developed a novel decision aid for patients in the emergency department (ED) with acute appendicitis who are facing this choice. We describe the development of the decision aid and an initial feasibility study of its implementation in a busy tertiary care ED.

Randomized Pilot Test of a Decision Support Tool for Acute Appendicitis: Decisional Conflict and Acceptability in a Healthy Population.

Unlabelled: To test the effect of a new decision support tool for acute appendicitis and assess its efficacy and acceptability.

Background: Mounting evidence from randomized controlled trials have shown that antibiotics can be a safe and effective treatment for appendicitis. Patients and surgeons must work together to choose the optimal treatment approach for each patient based on their own preferences and values.

What's in a Number? Assessing the Burden of Diverticular Disease.

In this prospective observational cohort of patients with a history of diverticulitis, we assessed the correlation between the diverticulitis quality of life survey (DVQOL) and other patient-reported expressions of disease measures including work and activity impairment, and contentment with gastrointestinal-related health. Then, we assessed whether the DVQOL is better correlated with these measures than diverticulitis episode count. Our study results showed that the DVQOL has a stronger correlation with other disease measures than diverticulitis episode count, and our findings support the broader use of the DVQOL in assessing the burden of diverticulitis and monitoring response to management.

Association of Patient Belief About Success of Antibiotics for Appendicitis and Outcomes: A Secondary Analysis of the CODA Randomized Clinical Trial.

Importance: A patient's belief in the likely success of a treatment may influence outcomes, but this has been understudied in surgical trials.

Objective: To examine the association between patients' baseline beliefs about the likelihood of treatment success with outcomes of antibiotics for appendicitis in the Comparison of Outcomes of Antibiotic Drugs and Appendectomy (CODA) trial.

Design, Setting, And Participants: This was a secondary analysis of the CODA randomized clinical trial.

Association Between Statewide Medicaid Opioid Policy and Postoperative Opioid Prescribing among Surgeons at a Large Safety-Net Hospital.

Background: Restrictive state and payer policies may be effective in reducing opioid prescribing by surgeons, but their impact has not been well studied. In 2017, Washington Medicaid implemented an opiod prescribing limit of 42 pills, prompting a large regional safety-net hospital to implement a decision support intervention in response. We aimed to evaluate the effects on surgeons' prescribing.

Applying Behavioral Nudges in a Dietary Comparator for Surgical Trials: Developing the MediDiet.

Introduction: Dietary interventions are increasingly being proposed as alternatives to surgery for common gastrointestinal conditions. Integrating aspects of cognitive psychology (e.g.

Perception of Treatment Success and Impact on Function with Antibiotics or Appendectomy for Appendicitis: A Randomized Clinical Trial with an Observational Cohort.

Objective: To compare secondary patient reported outcomes of perceptions of treatment success and function for patients treated for appendicitis with appendectomy vs. antibiotics at 30 days.

Summary Background Data: The Comparison of Outcomes of antibiotic Drugs and Appendectomy trial found antibiotics noninferior to appendectomy based on 30-day health status.
