Background: Opioid use beyond the perioperative period is a recognized adverse outcome, primarily studied in inpatients after complex major surgeries. Our goals are to determine the risk after ambulatory surgery and identify risk factors associated with long-term opioid prescriptions.
Methods: Our ambulatory surgery cohort included 1,393,332 veterans from October 1, 2011, to September 30, 2018 (fiscal year [FY] 12-18).
Background: Optimal postoperative opioid stewardship combines adequate pain medication to control expected discomfort while avoiding abuse and community diversion of unused prescribed opioids. We hypothesized that an opioid buyback program would motivate patients to return unused opioids, and surgeons will use that data to calibrate prescribing.
Methods: Prospective cohort study of postambulatory surgery pain management at a level II Veterans Affairs rural hospital (2017-2019).

To implement an opioid buyback program after ambulatory surgery. We performed a prospective cohort study of 578 opioid-naïve patients prescribed opioids after ambulatory surgery at a rural US Veterans Affairs (VA) hospital from 2017 to 2018. We reimbursed $5 per unused opioid pill ($50 limit) returned to our VA for proper disposal.

Methods: This validation study included 3 groups: patients with active GERD (n = 193), surgical patients with prior GERD (n = 197), and general medical outpatients (n = 63). All completed an initial survey.
Background: Persistent symptomatic gastroesophageal reflux disease (GERD) can be treated with medication or surgery. The purposes of this study were (1) to determine how poor the quality of life on medication would need to be to justify assuming the risks of surgery, and (2) to estimate the proportion of patients currently on medication whose quality of life is below this value.
Methods: We developed a Markov decision analysis model to simulate health outcomes (measured in quality adjusted life years [QALY]) over 10 years for medication and surgery in patients with typical GERD symptoms.
Background: Dialysis patients are undergoing coronary artery bypass grafting (CABG) with increasing frequency. The long-term effect of preoperative dialysis-dependent renal failure on mortality after CABG has not been well studied.
Methods: We conducted a prospective regional cohort study of 15,574 consecutive patients undergoing isolated CABG in northern New England from 1992 to 1997.
Hypothesis: Patients still have symptoms following laparoscopic antireflux surgery and require ongoing treatment.
Design: Mailed survey.
Setting: Academic tertiary care center.
