Rates of elective colectomy for diverticulitis continued to increase after 2006 guideline change.
Gastroenterology 2019 Dec;157(6):1679-81.e11. doi: 10.1053/j.gastro.2019.08.045.
The purpose of this retrospective cohort study was to assess whether trends in elective and urgent/emergent colectomy changed after July 2006. The authors suggest that given the risks associated with elective colectomy, their findings demonstrate the need for a more evidence-based decision-making process, incorporating both patient preferences and patient-reported outcomes, for those considering elective colectomy for uncomplicated and some cases of complicated diverticulitis.

Investigation of bias in an epilepsy machine learning algorithm trained on physician notes.
Racial disparities in the utilization of epilepsy surgery are well documented, but it is unknown whether a natural language processing (NLP) algorithm trained on physician notes would produce biased recommendations for epilepsy presurgical evaluations. To assess this, an NLP algorithm was trained to identify potential surgical candidates using 1097 notes from 175 epilepsy patients with a history of resective epilepsy surgery and 268 patients who achieved seizure freedom without surgery (total N = 443 patients).

Number of diverticulitis episodes before resection and factors associated with earlier interventions.
The authors described patterns of episodes of diverticulitis before surgery and factors associated with earlier interventions using inpatient, outpatient, and antibiotic prescription claims. They found that 56.3% of elective resections for uncomplicated diverticulitis occurred after fewer than 3 episodes. Further, they determined that earlier surgery was not explained by younger age, laparoscopy, time between the last 2 episodes preceding surgery, or financial risk-bearing for patients.

Stress testing before low-risk surgery: so many recommendations, so little overuse.
The researchers sought to determine the prevalence of cardiac stress testing before low-risk surgeries, prior to commencement of a campaign to reduce routine stress testing, in order to estimate the potential effect of the campaign on future use of resources. Their study of VA and Medicare patients found that the use of routine preoperative stress testing before low-risk surgeries was very low, suggesting that interventions to further decrease testing would minimally improve quality.
