Obesity has long been considered a risk factor for surgery. The purpose of this study was to evaluate the impact of obesity on outcomes after appendectomy. A retrospective study was performed using discharge abstract data obtained from patients with documented body mass index (BMI) undergoing appendectomy for appendicitis (n = 2919). Complications and length of stay for different BMI categories were compared. Obese patients (BMI > 30 kg/m2) had similar rates of perforation (20%) and were as likely to undergo a laparoscopic approach (85%) as nonobese patients. On multivariable and univariate analysis, no significant differences were observed when comparing obese and nonobese patients for the outcomes of length of stay, infectious complications, and need for readmission. On multivariate analysis, laparoscopy predicted lower complication rates and decreased length of stay. In this study, obesity did not significantly impact rates of perforation, operative approach, length of stay, infectious complications, or readmission.
Overdose of opioids is the number one cause of accidental death in the United States, and surgeons are overprescribing these medications. The aim of this study was to assess the feasibility of implementing postoperative opioid prescribing guidelines for general surgery procedures at a public hospital, where patients have lower socioeconomic status, public insurance, and limited access to care. We implemented a quality improvement project, which included in-service training for surgical staff and distribution of standardized guidelines. An infographic for patients was created to facilitate education on postoperative pain management. Pre- and postintervention opioid prescriptions and emergency room visits were compared for patients undergoing common general surgery procedures (inguinal hernia repair, appendectomy, and laparoscopic cholecystectomy). The median number of narcotic pills prescribed significantly decreased from 30 (n = 64) to 15 (n = 63) after the intervention ( P < 0.0001). Morphine milligram equivalents decreased from a median [range] of 150 [20,600] to 90 [5,300] ( P < 0.0001). The percentage of patients with postoperative pain-related emergency department visits remained low (1.6%). Standardization of postoperative opioid prescription practices was successfully implemented at a public hospital without an increase in the number of emergency room visits for pain.
ImportanceA patient’s belief in the likely success of a treatment may influence outcomes, but this has been understudied in surgical trials.ObjectiveTo 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 ParticipantsThis was a secondary analysis of the CODA randomized clinical trial. Participants from 25 US medical centers were enrolled between May 3, 2016, and February 5, 2020. Included in the analysis were participants with appendicitis who were randomly assigned to receive antibiotics in the CODA trial. After informed consent but before randomization, participants who were assigned to receive antibiotics responded to a baseline survey including a question about how successful they believed antibiotics could be in treating their appendicitis.InterventionsParticipants were categorized based on baseline survey responses into 1 of 3 belief groups: unsuccessful/unsure, intermediate, and completely successful.Main Outcomes and MeasuresThree outcomes were assigned at 30 days: (1) appendectomy, (2) high decisional regret or dissatisfaction with treatment, and (3) persistent signs and symptoms (abdominal pain, tenderness, fever, or chills). Outcomes were compared across groups using adjusted risk differences (aRDs), with propensity score adjustment for sociodemographic and clinical factors.ResultsOf the 776 study participants who were assigned antibiotic treatment in CODA, a total of 425 (mean [SD] age, 38.5 [13.6] years; 277 male [65%]) completed the baseline belief survey before knowing their treatment assignment. Baseline beliefs were as follows: 22% of participants (92 of 415) had an unsuccessful/unsure response, 51% (212 of 415) had an intermediate response, and 27% (111 of 415) had a completely successful response. Compared with the unsuccessful/unsure group, those who believed antibiotics could be completely successful had a 13–percentage point lower risk of appendectomy (aRD, −13.49; 95% CI, −24.57 to −2.40). The aRD between those with intermediate vs unsuccessful/unsure beliefs was −5.68 (95% CI, −16.57 to 5.20). Compared with the unsuccessful/unsure group, those with intermediate beliefs had a lower risk of persistent signs and symptoms (aRD, −15.72; 95% CI, −29.71 to −1.72), with directionally similar results for the completely successful group (aRD, −15.14; 95% CI, −30.56 to 0.28).Conclusions and RelevancePositive patient beliefs about the likely success of antibiotics for appendicitis were associated with a lower risk of appendectomy and with resolution of signs and symptoms by 30 days. Pathways relating beliefs to outcomes and the potential modifiability of beliefs to improve outcomes merit further investigation.Trial RegistrationClinicalTrials.gov Identifier: NCT02800785
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. To address questions about outcomes among participants with lower socioeconomic status, we explored the relationship of sociodemographic and clinical factors and outcomes. Methods: We focused on 4 patient reported outcomes at 30 days: high decisional regret, dissatisfaction with treatment, problems performing usual activities, and missing >10 days of work. The randomized (RCT) and observational cohorts were pooled for exploration of baseline factors. The RCT cohort alone was used for comparison of treatments. Logistic regression was used to assess associations. Results: The pooled cohort contained 2062 participants; 1552 from the RCT. Overall, regret and dissatisfaction were low whereas problems with usual activities and prolonged missed work occurred more frequently. In the RCT, those assigned to antibiotics had more regret (Odd ratios (OR) 2.97, 95% Confidence intervals (CI) 2.05–4.31) and dissatisfaction (OR 1.98, 95%CI 1.25–3.12), and reported less missed work (OR 0.39, 95%CI 0.27–0.56). Factors associated with function outcomes included sociodemographic and clinical variables for both treatment arms. Fewer factors were associated with dissatisfaction and regret. Conclusions: Overall, participants reported high satisfaction, low regret, and were frequently able to resume usual activities and return to work. When comparing treatments for appendicitis, no single measure defines success or failure for all people. The reported data may inform discussions regarding the most appropriate treatment for individuals. Trial Registration: Clinicaltrials.gov Identifier: NCT02800785.
