Validating an opioid prescribing algorithm in post-operative pediatric surgical oncology patients

A Narrative Review of Pain in Pediatric Oncology: The Opioid Option for Procedural and Surgical Pain

This narrative review examines the evolving role of opioids in managing procedural and surgical pain in pediatric oncology patients. The review evaluates studies on opioid use across various oncological surgeries including thoracic, abdominal, orthopedic, and neurosurgical procedures, as well as for common painful procedures such as bone marrow aspirations and lumbar punctures. While opioids remain important for acute procedural and postoperative pain management in pediatric oncology patients, there is an increasing emphasis on multimodal, opioid-sparing approaches. The evidence presented within this review highlights the growing focus on judicious postoperative opioid prescribing to mitigate risks of adverse effects and persistent use or potential misuse. The review synthesizes findings from studies investigating various analgesic regimens, including the use of regional anesthesia techniques like epidural analgesia and peripheral nerve blocks, which have shown promise in reducing opioid requirements. For procedural pain, the review explores the efficacy of combining opioids with sedatives like midazolam or propofol, as well as the potential of ketamine as an opioid-sparing alternative. Key findings indicate that opioid-sparing techniques can effectively reduce overall opioid consumption without compromising pain control or patient satisfaction. Several studies demonstrated that regional anesthesia techniques and non-opioid adjuncts can significantly lower postoperative opioid requirements across various surgical procedures. For procedural pain, ketamine-based regimens often showed comparable or superior pain control to opioid-based approaches, with some studies reporting better patient satisfaction. This review also addresses the importance of tailored postoperative opioid prescribing, with some studies presenting algorithms to predict outpatient opioid needs more accurately. These approaches aim to ensure adequate pain control while minimizing excess opioid dispensing.

Factors Associated with Postoperative Opioid Use in Adolescents

BACKGROUND

We aimed to identify factors associated with postoperative prescription opioid use in adolescents.

METHODS

Adolescents aged 13-20 years undergoing surgery were prospectively recruited from a children's hospital. Adolescent-parent dyads completed a preoperative survey, measuring clinical and sociodemographic factors, and two postoperative surveys evaluating self-reported opioid use at 30- and 90-days. Poisson regression analysis identified factors associated with the number of pills used within 90-days, adjusting for age, gender, race/ethnicity, surgery type, and pain at discharge.

RESULTS

We enrolled 119 adolescents who reported postoperative opioid use following posterior spinal fusion (PSF) (50 %), arthroscopy (23 %), pectus excavatum repair (11 %), tonsillectomy (8 %), and hip reconstruction (7 %). Overall, 81 % of adolescents reported unused opioids. The median pain score at discharge was 7 (IQR:5-8). Adolescents reported using a median of 7 (IQR:2-15) opioid pills, with 20 (IQR:7-30) pills left unused. Compared to all other surgeries, adolescents undergoing PSF reported the highest median pill use (10, IQR:5-29; p = 0.004). Adolescents undergoing tonsillectomy reported the lowest median pill use (1, IQR:0-7; p = 0.03). On regression analysis, older patient age was associated with a 12 % increase in pill use (95 % CI:3%-23 %). Undergoing PSF was associated with a 63 % increase in pill use (95 % CI:15%-31 %). Each additional pain scale point reported at discharge was associated with a 13 % increase in pill use (95 % CI:5%-22 %).

CONCLUSIONS

Older age, surgery type, and patient-reported pain at discharge are associated with postoperative prescription opioid use in adolescents. Understanding patient and surgery-specific factors associated with opioid use may guide surgeons to minimize excess opioid prescribing.

Factors Associated With Safe Prescription Opioid Disposal After Surgery in Adolescents

INTRODUCTION

Unused prescription opioids contribute to diversion, unintended exposure, and poisonings in adolescents. Factors associated with safe prescription opioid disposal for adolescents undergoing surgery are unknown.

METHODS

Parents of adolescents (13-20 y) undergoing surgery associated with an opioid prescription were enrolled preoperatively. Parents completed a baseline survey measuring sociodemographics and family history of substance abuse and two postoperative surveys capturing opioid use and disposal at 30 and 90 d. Safe disposal was defined as returning opioids to a healthcare facility, pharmacy, take-back event, or a police station. Factors associated with safe opioid disposal were assessed using bivariate analysis.

RESULTS

Of 119 parent-adolescent dyads, 90 (76%) reported unused opioids after surgery. The majority of parents reporting unused opioids completed the surveys in English (80%), although many (44%) spoke another language at home. Most reported income levels <$60,000 (54%), did not attend college (69%), and had adequate health literacy (66%). Most parents (78%) did not report safe opioid disposal. Safe opioid disposal was associated with younger patient age, (median 14 y, IQR 13-16.5 versus median 15.5 y, IQR 14-17, P = 0.031), fewer days taking opioids (median 5, IQR 2-6 versus median 7, IQR 4-14, P = 0.048), and more leftover pills (median 20, IQR 10-35 versus median 10, IQR 5-22, P = 0.008).

CONCLUSIONS

Most parents fail to safely dispose of unused opioids after their adolescent's surgery. Younger patient age, shorter duration of opioid use, and higher number of unused pills were associated with safe disposal. Interventions to optimize prescribing and educate parents about safe opioid disposal are warranted.

Postoperative Opioid Prescribing, Use, and Disposal in Children

This article provides an overview of postoperative opioid prescribing, use, and disposal patterns in children and also identifies gaps in knowledge and areas for improvement. We present evidence that there is a need to tailor prescriptions to specific procedures to reduce the number of excess, unused prescription opioid pills in the home. We also explain the need to provide culturally competent care when managing a child's pain after surgery. Finally, we discuss the need for widespread provider and caregiver education about safe prescription opioid use, storage, and disposal.

Guideline for Children With Cancer Receiving General Anesthesia for Procedures and Imaging

Children with cancer and those undergoing hematopoietic stem cell transplantation frequently require anesthesia for imaging as well as diagnostic and therapeutic procedures from diagnosis through follow-up. Due to their underlying disease and side effects of chemotherapy and radiation, they are at risk for complications during this time, yet no published guideline exists for preanesthesia preparation. A comprehensive literature review served as the basis for discussions among our multidisciplinary panel of oncologists, anesthesiologists, nurse practitioners, clinical pharmacists, pediatric psychologists, surgeons and child life specialists at the Children's Hospital of Philadelphia. Due to limited literature available, this panel created an expert consensus guideline addressing anesthesia preparation for this population.
