Evaluation of Opioid Prescription and Consumption Habits Following Endovascular Aortic Aneurysm Repair

Opioid sparing effects of the bupivacaine pleural catheter in surgical decompression of the thoracic outlet

OBJECTIVE

Rib resection in thoracic outlet decompression can result in significant postoperative pain requiring high levels of opioid medications. We evaluated the impact of a bupivacaine infusing pleural catheter on postoperative pain and opioid usage in patients undergoing rib resection for thoracic outlet syndrome. We hypothesized that delivery of local anesthetic via the pleural catheter would improve postoperative pain control compared to standard multimodal analgesia, and that the use of the catheter would decrease opioid use during the index hospitalization and prescriptions for opioid pain medications at discharge.

METHODS

We conducted a single-center retrospective cohort study of 26 patients who underwent rib resection for thoracic outlet decompression. Primary outcome was opioid consumption during the index hospitalization, measured in morphine milligram equivalents (MME). Secondary outcomes were MME prescribed at discharge and pain scores during the index hospitalization before and after the pleural drain and pleural catheter were removed.

RESULTS

Patients in the bupivacaine infusion pleural catheter group (n=11) had significantly lower milligram morphine equivalent (MME) usage during the index hospitalization (22.5 [1.9, 65.6] vs. 119.8 [76.5, 167.4]), and significantly lower MME prescribed at discharge (0 [0, 37.5] vs. 225 [183, 315]), compared to standard multimodal analgesia in controls (n=15). Only 3 patients in the bupivacaine pleural catheter group were discharged with any opioid prescriptions (27%), compared to 14 patients in the control group (93%). There was no difference in postoperative pain scores between groups before or after removal of the pleural drain, which was placed in all cases (p=0.31 and p=0.76, respectively).

CONCLUSIONS

Intraoperative placement of a bupivacaine infusion pleural catheter significantly reduced opioid use during the index hospitalization and opioid prescribing at discharge. Anesthetic infusion pleural catheters should be the treatment modality of choice for postoperative pain management in patients undergoing thoracic outlet decompression.

Impact of a regional smoking cessation intervention for vascular surgery patients

OBJECTIVE

Tobacco use is common among vascular surgery patients and negatively impacts outcomes and longevity. In the second quarter of 2018, a statewide vascular quality collaborative launched an initiative across its 35 participating hospitals to promote smoking cessation at the time of surgery. This intervention was based on the Vascular Physician Offer and Report (VAPOR) trial and consisted of 3 components: brief physician-delivered advice, referral to telephone-based counseling, and nicotine replacement therapy. The goal of this study is to evaluate the results of this intervention.

METHODS

We performed a retrospective analysis of patients undergoing vascular surgery between 2018 and 2020. Procedures included open abdominal aortic aneurysm repair, endovascular aneurysm repair, open vascular bypass, open thrombectomy, carotid endarterectomy, and carotid stenting. The primary explanatory variables were receipt of tobacco cessation interventions as documented in the medical record. The primary outcome was tobacco cessation, captured during 30-day and 1-year chart review and/or patient follow-up. A multivariable logistic regression model was calculated to estimate the association of covariates with smoking cessation while adjusting for patient and clinical characteristics.

RESULTS

A total of 13,890 patients underwent surgery during the study period. The mean age was 69.4 ± 10 years; 4687 patients (34%) were female, and 5158 patients (37%) were current smokers. At least one smoking cessation component was delivered to 2245 patients (44% of smokers). The quit rate was 35% among 4671 patients with 30-day follow-up and 43% among 2936 patients with 1-year follow up. On multivariable regression, at 30 days, receiving two intervention components was associated with 1.29 (95% confidence interval [CI], 1.07-1.55) higher odds of quitting. At both time points, smoking cessation was also associated with undergoing an emergent procedure (30-day odds ratio [OR], 1.52; 95% CI, 1.16-1.99; 1-year OR, 1.41; 95% CI, 1.01-1.97) and undergoing open abdominal aortic aneurysm repair (30-day OR, 1.71; 95% CI, 1.20-2.43; 1-year OR, 1.75; 95% CI, 1.11-2.78).

CONCLUSIONS

In a cohort of vascular surgical patients where tobacco use was common, nearly one-half of patients quit smoking 1 year after surgery. Receiving two smoking cessation intervention components was associated with quitting at 30 days. Overall, these results demonstrate encouraging quit rates and identify an opportunity for longer-term intervention to maintain even greater 1-year tobacco cessation.
