Effective Reduction in Opioid Prescriptions for Ambulatory Lesion Excisions in Pediatric Patients.

Childhood opioid consumption is potentially deleterious to cognitive development and may predispose children to later addiction. Opioids are frequently prescribed for outpatient surgery but may not be necessary for adequate pain control. We aimed to reduce opioid prescriptions for outpatient pediatric skin and soft tissue lesion excisions using quality improvement (QI) methods. METHODS: A multidisciplinary team identified drivers for opioid prescriptions. Interventions were provider education, improving computer order set defaults, and promoting non-narcotic pain control strategies and patient-family education. Outcomes included percentage of patients receiving opioid prescriptions and patient-satisfaction scores. Data were retrospectively collected for 3 years before the QI project and prospectively tracked over the 8-month QI period and the following 18 months. RESULTS: The percentage of patients receiving an opioid prescription after outpatient skin or soft tissue excision dropped significantly from 18% before intervention to 6% at the end of the intervention period. Patient-reported satisfaction with pain control improved following the QI intervention. Satisfaction with postoperative pain control was independent of closure size or receipt of a postoperative opioid prescription. Intraoperative use of lidocaine or bupivacaine significantly decreased the incidence of postoperative opioid prescription in both bivariate and multivariate analyses. Results were maintained at 18 months after the conclusion of the QI project. CONCLUSION: Raising provider awareness, educating patients on expected postoperative pain management options, and prioritizing non-narcotic medications postoperatively successfully reduced opioid prescription rates in children undergoing skin and soft tissue lesion excisions and simultaneously improved patient-satisfaction scores.

The Effects of Adjunctive Pain Medications on Postoperative Inpatient Opioid Use in Abdominally Based Microsurgical Breast Reconstruction.

BACKGROUND: The purposes of this study were to quantify the amount of opioid medication used postoperatively in the hospital setting after abdominally based microsurgical breast reconstruction, to determine factors that are associated with increased opioid use, and to identify other adjunctive medications that may contribute to decreased opioid use. METHODS: An electronic medical record data pull was performed at the University of Pennsylvania from November 2016 to October 2018. Cases were identified using Current Procedural Terminology code 19364. Only traditional recovery after surgery protocol patients were included. Patient comorbidities, surgical details, and pain scores were captured. Postoperative medications including non-patient-controlled analgesia opioid use and adjunctive nonopioid pain medications were recorded. Non-patient-controlled analgesia total opioid use was calculated and converted to oral morphine milligram equivalents (mme). Statistical analysis was performed using t test analyses and linear regression. RESULTS: A total of 328 patients satisfied our inclusion criteria. Five hundred forty free flaps were performed (212 bilateral vs 116 unilateral, 239 immediate vs 89 delayed). Bilateral patients used on average 115.2 mme (95% confidence interval [CI], 103.4-127.0 mme) compared with 89.0 mme in unilateral patients (95% CI, 70.0-108.0 mme; P = 0.015). Patients with abdominal mesh placement (n = 249) required 113.0 mme (95% CI, 100.5-125.5 mme) compared with 83.8 mme (95% CI, 68.8-98.7 mme) for patients without mesh (n = 79; P = 0.016). Each additional hour of surgery increased postoperative mme by 9.4 (P < 0.01). Patients with a nonzero preoperative pain score required 100.3 mme (95% CI, 90.2-110.4 mme) compared with 141.1 mme (95% CI, 102.7-179.7 mme) for patients with preoperative pain score greater than 0/10 (P < 0.01). Patients with postoperative index pain score ≤5/10 required 89.2 mme (95% CI, 78.6-99.8 mme) compared with 141.1 mme (95% CI, 119.9-162.2 mme) for patients with postoperative index pain score >5/10 (P < 0.01). After regression analysis, a dose of intravenous acetaminophen 1000 mg was found to decrease postoperative mme by 11.7 (P = 0.024). A dose of oral ibuprofen 600 mg was found to decrease postoperative mme by 8.3 (P < 0.01). CONCLUSIONS: Bilateral reconstruction and longer surgery resulted in increased postoperative mme. Patients with no preoperative pain required less opioids than did patients with preexisting pain. Patients with good initial postoperative pain control required less opioids than did patients with poor initial postoperative pain control. Intravenous acetaminophen and oral ibuprofen were found to significantly decrease postoperative mme.

On Cuba, diplomats, ultrasound, and intermodulation distortion.

This paper analyzes how ultrasounds could have unintentionally led to the AP news recordings of metallic sounds heard by diplomats in Cuba. Beginning with screen shots of the acoustic spectral plots from the AP news, we reverse engineered ultrasonic signals that could lead to those outcomes as a result of intermodulation distortion with non-linearity in the acoustic transmission medium. We created a proof of concept ultrasonic device that amplitude modulates a signal over an inaudible ultrasonic carrier. When a second inaudible ultrasonic source interfered with the primary source, intermodulation distortion created audible byproducts that share spectral characteristics with audio from the AP news. Our conclusion is that if ultrasound played a role in harming diplomats in Cuba, then a plausible cause is intermodulation distortion between ultrasonic signals that unintentionally synthesize audible tones. In other words, acoustic interference without malicious intent to cause harm could have led to the audible sensations in Cuba.

The Value of a Resident Aesthetic Clinic: A 7-Year Institutional Review and Survey of the Chief Resident Experience.

BACKGROUND: With the evolving plastic surgery training paradigm, there is an increasing emphasis on aesthetic surgery education during residency. In an effort to improve aesthetic education and to encourage preparation for independent practice, our institution has supported a resident-run aesthetic clinic for over two decades. OBJECTIVES: To provide insight into the educational benefits of a resident-run cosmetic clinic through longitudinal resident follow up and institutional experiential review. METHODS: A retrospective review was conducted to identify all clinic-based aesthetic operations performed between 2009 and 2016. To capture residents' perspectives on the cosmetic resident clinic, questionnaires were distributed to the cohort. Primary outcome measures included: volume and types of cases performed, impact of clinic experience on training, confidence level performing cosmetic procedures, and satisfaction with chief clinic. Unpaired t tests were calculated to compare case volume/type with level of confidence and degree of preparedness to perform cosmetic procedures independently. RESULTS: Overall, 264 operations performed by 18 graduated chief residents were reviewed. Surveys were distributed to 28 chief residents (71.4% completion rate). Performing twenty or more clinic-based procedures was associated with higher levels of preparedness to perform cosmetic procedures independently (P = 0.037). Residents reported the highest confidence when performing cosmetic breast procedures when compared to face/neck (P = 0.005), body/trunk procedures (P = 0.39), and noninvasive facial procedures (P = 0.85). CONCLUSIONS: The continued growth of aesthetic surgery highlights the need for comprehensive training and preparation for the new generation of plastic surgeons. Performing cosmetic procedures in clinic is a valuable adjunct to the traditional educational curriculum and increases preparedness and confidence for independent practice.

The impact of obesity on abdominal wall function after free autologous breast reconstruction.

BACKGROUND: The functional impact of obesity on abdominal wall strength after abdominally based autologous reconstruction is unknown. The purpose of this study was to determine if obesity alters the postoperative abdominal wall strength profile after autologous reconstruction. METHODS: We prospectively examined abdominal wall strength and function following autologous breast reconstruction between 2005 and 2010. Enrolled patients completed functional testing [upper abdominal strength (UA), lower abdominal strength (LA), and functional independence measure (FIM)] and psychometric testing utilizing the short form 36 (SF36). Data were obtained at preoperative, early (<90d), and late (90-365d) follow-up visits. Obese patients were compared with non-obese patients in both unilateral and bilateral reconstructions. RESULTS: Overall, 167 patients were enrolled, with obesity noted in 34% of patients. Obese Unilateral reconstruction patients had lower preoperative UA strength (4.7 vs.4.2, P=0.05) and FIM (6.7 vs. 6.9, P=0.008) scores compared with non-obese patients. These scores significantly worsened in all patients from preoperative to early follow-up, yet scores did not differ at late follow-up between obesity cohorts. Obese bilateral reconstruction patients had similar preoperative functional scores; however, UA strength scores at early (2.5 vs. 3.2, P=0.008) and late (3.6 vs. 4.3, P=0.005) follow-up were significantly lower compared with non-obese patients. No differences in subjective health were noted in follow-up for unilateral or bilateral reconstructions. CONCLUSION: Obesity significantly impacts the abdominal function profile of autologous breast reconstruction patients; however, subjective physical and mental health differences are less notable. This is especially true for obese patients who undergo bilateral reconstructions. In these patients, a careful balance between optimizing flap perfusion, limiting donor site morbidity, and enabling functional recovery should be considered.
