Opioid Use, Disposition, and Parent Satisfaction Following Common Pediatric Surgical Procedures.

INTRODUCTION: There is wide variability in prescribing practices among providers, even for patients undergoing the same operations. Our study aims to analyze the variation in opioid prescription practices using a patient-centered approach to establish more appropriate prescribing guidelines for health care providers. METHODS: We conducted phone surveys 30 days after surgery to assess patient-reported opioid use. Over a two-year collection period, we identified patients that had undergone common outpatient pediatric surgery procedures in our 4-surgeon group. Included in the survey tool was the narcotic prescribed (if any), the amount used, and patient/family rating of pain control. RESULTS: We collected data for 189 separate procedures (88 umbilical hernias, 30 laparoscopic inguinal hernias, 2 open inguinal hernias, 41 appendectomies, 15 laparoscopic cholecystectomies, and 13 pectus bar removals). Patient age ranged from less than 1 month to 246 months. 83.5% of patients had a narcotic prescribed. The average number of doses used was 4, ranging from 0 (11.3%) to 30 (1.5%). 72.6% of families surveyed felt pain control was appropriate. However, 19.6% did feel they received too much pain medication. 10.6% reported completing their entire prescription; however, only 13.6% of families with excess narcotics reported proper disposal. CONCLUSIONS: Despite heightened awareness of the opioid epidemic, there is still a poor understanding of appropriate pain control regimens in the pediatric surgical population. We demonstrate that most patients are discharged home with excess opioids and that many families save the leftover pills/liquid. Further research and education are encouraged to limit the use of opioids in standard pediatric surgical procedures.

Specialty-specific reduction in opioid prescribing after common pediatric surgical operations.

BACKGROUND: Opioid misuse has reached epidemic proportions, and postoperative opioids have been linked to overdose, diversion, and dependency. We recently found our opioid prescribing practices following common pediatric operations to be inconsistent and excessive. In this study, we evaluate the efficacy of an educational intervention on opioid prescriptions following tonsillectomy and hernia repair. METHODS: Retrospective chart review of prescriptions following outpatient tonsillectomies and hernia repairs at a single institution before and after an educational intervention was performed. The intervention consisted of a single campus-wide grand rounds presentation detailing the surgeon's role in the opioid epidemic. RESULTS: Postoperative opioid prescriptions were significantly reduced for hernia repair following the educational intervention: 4.2 ± 2.9 vs 2.7 ± 2.6 days' supply (p = 0.004). Such a reduction was not observed for post-tonsillectomy opioid prescriptions: 6.3 ± 4.4 vs 5.4 ± 3.0 days' supply (p = 0.226). A greater decrease in interprovider variation was observed for hernia providers after the educational intervention than for tonsillectomy providers, though significant variation continued to be present for both procedures after the intervention. CONCLUSIONS: The efficacy of an educational intervention at reducing postoperative pediatric opioid prescribing may be tied to the specialty-specific role model relationship of the educator to the prescriber. TYPE OF STUDY: retrospective comparative chart review. LEVEL OF EVIDENCE: IV.

Cardif (MAVS) Regulates the Maturation of NK Cells.

Cardif, also known as IPS-1, VISA, and MAVS, is an intracellular adaptor protein that functions downstream of the retinoic acid-inducible gene I family of pattern recognition receptors. Cardif is required for the production of type I IFNs and other inflammatory cytokines after retinoic acid-inducible gene I-like receptors recognize intracellular antigenic RNA. Studies have recently shown that Cardif may have other roles in the immune system in addition to its role in viral immunity. In this study, we find that the absence of Cardif alters normal NK cell development and maturation. Cardif(-/-) mice have a 35% loss of mature CD27(-)CD11b(+) NK cells in the periphery. In addition, Cardif(-/-) NK cells have altered surface marker expression, lower cytotoxicity, decreased intracellular STAT1 levels, increased apoptosis, and decreased proliferation compared with wild-type NK cells. Mixed chimeric mice revealed that the defective maturation and increased apoptotic rate of peripheral Cardif(-/-) NK cells is cell intrinsic. However, Cardif(-/-) mice showed enhanced control of mouse CMV (a DNA ß-herpesvirus) by NK cells, commensurate with increased activation and IFN-γ production by these immature NK cell subsets. These results indicate that the skewed differentiation and altered STAT expression of Cardif(-/-) NK cells can result in their hyperresponsiveness in some settings and support recent findings that Cardif-dependent signaling can regulate aspects of immune cell development and/or function distinct from its well-characterized role in mediating cell-intrinsic defense to RNA viruses.
