Opioid use in children's surgery: Awareness, current state, and advocacy

Trends in analgesia-sedation of pediatric patients receiving I-131 MIBG in the pediatric intensive care unit: A report from the Pediatric Health Information System database

BACKGROUND

Children with neuroblastoma receiving I-131 metaiodobenzylguanidine (MIBG) therapy require sedation-analgesia for strict radiation safety precautions during MIBG infusion and clearance. We evaluated the sedation-analgesia trends of patients undergoing MIBG therapy using the Pediatric Health Information System (PHIS) database.

MATERIALS AND METHODS

Retrospective data from 476 patient encounters from the PHIS from 2010 to 2019.

RESULTS

Total 240/476 (50.45%) children evaluated were under 6 years of age. Compared to 2010, in 2018 there was a decrease in benzodiazepine infusion use (60% vs. 40%, p < .04), as well as a decrease in use of opiate infusion (35% vs. 25%, p < .001). Compared to 2010, in 2018 we report an increase in the use of ketamine (from 5% to 10%, p < .002), as well as an increase in dexmedetomidine use (0% vs. 30%, p < .001). Dexmedetomidine was the most used medication in the 0-3 years age group compared to children older than 3 years of age (14.19% vs. 5.80%, p < .001). Opiate was the most used medication in children greater than 3 years compared to the 0-3-year age group (36.23 vs. 23.87, p < .05).

CONCLUSION

Using PHIS data, we discovered considerable variability in the medications used for sedation in patients undergoing MIBG therapy. Although benzodiazepines and opioids were the most used agents, there was a trend toward decreasing use of benzodiazepines and opioids in these patients. Furthermore, there has been an increasing trend in the use of dexmedetomidine and ketamine.

Use of regional anesthesia within a pediatric interventional radiology suite reduced periprocedural opioid use without delaying the overall workflow: a retrospective study

BACKGROUND

Nerve block utility has been extensively described in the operating room, however, there is a paucity of evidence regarding blocks in the interventional radiology (IR) suite, with no studies examining its safety and efficacy in children.

METHODS

A retrospective study was conducted at a single tertiary-care children's hospital to evaluate the analgesic utility of nerve blocks during IR-performed sclerotherapy for bone cysts, venous malformations, and lymphatic malformations. Lymphatic and venous malformations were combined for final analysis. Patients between January 2016 and September 2022 had their medical records reviewed for procedural data, postprocedural pain scores, and analgesic administration data.

RESULTS

309 patients were included in the final analysis. Opioids were required significantly less frequently intraprocedurally and postprocedurally across subgroups. The proportion of patients who received opioids during their hospital course was significant between block and non-block patients, respectively: bone cyst: 62.7% vs 100% (p<0.001); venous and lymphatic malformation: 65.7% vs 97.4% (p<0.001). Average maximum postanesthesia care unit (PACU) pain scores were significantly lower in bone cyst patients with no significant difference seen in pain scores among venous and lymphatic malformation patients. There were no reported nerve block-related complications.

DISCUSSION

Nerve blocks demonstrated an opioid-sparing effect intraprocedurally and postprocedurally for all subgroups. Their use among bone cyst patients was associated with significant reductions in average maximum PACU pain scores. Nerve blocks may constitute an effective opioid-sparing component of multimodal analgesia in pediatric patients undergoing IR sclerosis procedures. Prospective data are needed to establish the optimal utility of nerve blocks in the IR setting.

Children and the Opioid Crisis: We Can Make a Difference

The use of opioid-sparing and opioid-free strategies in children can provide adequate analgesia while decreasing the risk of adverse events and contributing to the ongoing battle against the opioid crisis. However, every child must be evaluated individually so that a safe and efficacious perioperative pain management plan can be created. A working knowledge of the risks and benefits of opioids, nonopioid adjuncts, and regional anesthesia along with the ethical considerations for balancing stewardship and beneficent care is essential to the success of these strategies. As perioperative practitioners caring for children, we have an obligation to consider opioid-sparing and opioid-free strategies to promote overall best outcomes. We can make a difference, one child at a time.

Trends in sedation-analgesia practices in pediatric liver transplant patients admitted postoperatively to the pediatric intensive care unit: An analysis of data from the pediatric health information system (PHIS) database

BACKGROUND

Children admitted to the pediatric intensive care unit (PICU), after liver transplantation, frequently require analgesia and sedation in the immediate postoperative period. Our objective was to assess trends and variations in sedation and analgesia used in this cohort.

METHODS

Multicenter retrospective cohort study using the Pediatric Health Information System from 2012 to 2022.

RESULTS

During the study period, 3963 patients with liver transplantation were admitted to the PICU from 32 US children's hospitals with a median age of 2 years [IQR: 0.00, 10.00]. 54 percent of patients received mechanical ventilation (MV). Compared with patients without MV, those with MV were more likely to receive morphine (57% vs 49%, p < .001), fentanyl (57% vs 44%), midazolam (45% vs 31%), lorazepam (39% vs. 24%), dexmedetomidine (38% vs 30%), and ketamine (25% vs 12%), all p < .001. Vasopressor usage was also higher in MV patients (22% vs. 35%, p < .001). During the study period, there was an increasing trend in the utilization of dexmedetomidine and ketamine, but the use of benzodiazepine decreased (p < .001).

CONCLUSION

About 50% of patients who undergo liver transplant are placed on MV in the PICU postoperatively and receive a greater amount of benzodiazepines in comparison with those without MV. The overall utilization of dexmedetomidine and ketamine was more frequent, whereas the administration of benzodiazepines was less during the study period. Pediatric intensivists have a distinctive opportunity to collaborate with the liver transplant team to develop comprehensive guidelines for sedation and analgesia, aimed at enhancing the quality of care provided to these patients.

Reducing Unplanned Intubations in the Neonatal Intensive Care Unit After Children's Surgery: A Quality Improvement Project

BACKGROUND

Unplanned intubation following children's surgery is associated with increased postoperative mortality. In response to being a National Surgical Quality Improvement Program - Pediatric (NSQIP-P) high outlier for postoperative unplanned intubation, we aimed to reduce postoperative unplanned intubation events by 25% in one year.

METHODS/INTERVENTION

A multidisciplinary team of stakeholders was assembled in 2018. Most unplanned intubation events occurred in the neonatal intensive care unit (NICU). Based on apparent causes of unplanned intubations identified in case reviews, an extubation readiness checklist and a postoperative pain management guideline emphasizing non-opioid analgesics were implemented for NICU patients in September 2019. Postoperative unplanned intubation events were tracked prospectively and evaluated using quality improvement statistical process control methods.

RESULTS

Unplanned intubations in the NICU decreased from 0.27 to 0.07 events per patient in the post-intervention group (September 2019-June 2022, n = 145) compared to the pre-intervention group (January 2016-August 2019, n = 200), representing a 76% reduction. Postoperative opioid administration decreased significantly, while acetaminophen usage increased significantly over time. Balancing measures of postoperative pneumonia rate (1.5% vs 0.0%, p = 0.267) and median hospital length of stay [40 (IQR 51) days vs 27 (IQR 60), p = 0.124] were not different between cohorts. The 30-day mortality rate for postoperative patients in the NICU significantly declined [6.5% (n = 13) vs 0.7% (n = 1), p < 0.001].

CONCLUSIONS

Postoperative unplanned intubation rates for NICU patients decreased following a quality improvement effort focused on opioid stewardship and extubation readiness.

Patient-Reported Outcomes in Pain Management After Ambulatory Pediatric General and Urologic Surgery

BACKGROUND

Many studies evaluating opioid stewardship interventions' effects on postoperative pain rely on emergency department (ED) visits or readmissions, but patient-reported pain scores represent a more complete picture of the postoperative experience. This study compares patient-reported pain scores after ambulatory pediatric and urologic procedures and the effect of an opioid stewardship intervention that nearly eliminated the use of outpatient narcotics.

METHODS

This is a retrospective comparative study including 3173 pediatric patients who underwent ambulatory procedures from 2015 to 2019, during which there was an intervention to reduce narcotic prescriptions. Postoperative day one phone calls assessed pain levels using a four-point scale (no pain, mild pain, moderate pain controlled with medication, or severe pain uncontrolled with medication). We quantified the proportion of patients prescribed opioids pre-versus post-intervention and compared pain scores for patients receiving opioid versus non-opioid regimens.

RESULTS

Opioid prescription rates demonstrated a 6.5-fold reduction after opioid stewardship efforts. The majority of patients (2838) received non-opioids, with only 335 patients receiving opioids. Opioid patients reported moderate/severe pain slightly more than non-opioid patients (14.1% vs. 10.4%, p = 0.04). On by-procedure analyses, there were no subgroups in which non-opioid patients reported significantly higher pain scores.

CONCLUSIONS

Non-opioid postoperative pain regimens appear to be effective, with only 10.4% of patients reporting moderate/severe pain after ambulatory procedures. Future studies assessing patient-reported outcomes are necessary to optimize pain control for all patients and to determine whether there is ever an indication for opioid prescription after ambulatory general pediatric or urologic surgery.

The past, present and future of ACS NSQIP-Pediatric: Evolution from a quality registry to a comparative quality performance platform

Quality and process improvement (QI/PI) in children's surgical care require reliable data across the care continuum. Since 2012, the American College of Surgeons' (ACS) National Surgical Quality Improvement Program-Pediatric (NSQIP-Pediatric) has supported QI/PI by providing participating hospitals with risk-adjusted, comparative data regarding postoperative outcomes for multiple surgical specialties. To advance this goal over the past decade, iterative changes have been introduced to case inclusion and data collection, analysis and reporting. New datasets for specific procedures, such as appendectomy, spinal fusion for scoliosis, vesicoureteral reflux procedures, and tracheostomy in children less than 2 years old, have incorporated additional risk factors and outcomes to enhance the clinical relevance of data, and resource utilization to consider healthcare value. Recently, process measures for urgent surgical diagnoses and surgical antibiotic prophylaxis variables have been developed to promote timely and appropriate care. While a mature program, NSQIP-Pediatric remains dynamic and responsive to meet the needs of the surgical community. Future directions include introduction of variables and analyses to address patient-centered care and healthcare equity.

Pilot implementation of opioid stewardship measures using the national surgical quality improvement program-pediatric platform

INTRODUCTION

Data surrounding optimal pediatric postoperative opioid prescribing are incomplete. The objective of this study was to leverage the American College of Surgeons (ACS) National Surgical Quality Improvement Program-Pediatric (NSQIP-P) and assess feasibility of added data collection surrounding pediatric perioperative pain management practices including opioid prescribing at discharge.

METHODS

Nineteen (19) novel data elements were added to NSQIP-P data collection of selected patients, ages 5-18 years, who had undergone surgery at a single, free-standing children's hospital. Metrics around data abstraction and completion of variables were collected. Univariate analyses (using Chi-square or Wilcoxon Rank Sum tests) and multiple logistic regressions were performed to describe predictors of opioid prescribing at discharge and to monitor adherence to Food and Drug Administration (FDA) prescribing recommendations.

RESULTS

Median abstraction time of the novel variables decreased from 12 to 5 min per patient over 13 months with 94% variable completion rate. Of 878 patients, 302 (36.4%) were prescribed opioids at discharge. Factors associated with an opioid prescription included older age (p < 0.001), white race (p < 0.05), undergoing an orthopedic surgery (p < 0.001), and receiving a regional block perioperatively (p < 0.001). All opioid prescriptions met FDA guidelines with no patients receiving codeine, and 98% of patients receiving opioid prescriptions < 50 morphine milli-equivalents per day.

CONCLUSION

Collecting data on current pain management practices, opioid prescribing, and adherence to safety recommendations is feasible using the NSQIP-P with little added burden. Further expansion of data collection is needed to develop generalizable optimal prescribing practices for post-discharge pain management for children.

Ketorolac use and risk of bleeding after appendectomy in children with perforated appendicitis

BACKGROUND

Ketorolac is an opioid sparing agent commonly used in children. However, ketorolac may be avoided in children with peritonitis owing to a possible increased risk of bleeding.

METHODS

A retrospective cohort study of healthy children 2-18 years who underwent appendectomy for perforated appendicitis was performed using the Pediatric Health Information System (2009-2019). Multivariable logistic regression was used to evaluate the association between perioperative ketorolac use and postoperative blood transfusions within 30 days of surgery, adjusting for patient and hospital level factors. An interaction between ketorolac and ibuprofen was evaluated to identify synergistic effects.

RESULTS

Overall, 55,603 children with perforated appendicitis underwent appendectomy and 82.3% (N = 45,769) received ketorolac. Of those, 32% (N = 14,864) also received ibuprofen. Receipt of a blood transfusion was infrequent (N = 189, 0.3%). On multivariable logistic regression analysis, perioperative ketorolac administration was associated with decreased odds of a blood transfusion (OR 0.53, 95% CI: 0.35-0.79). However, children receiving ketorolac and ibuprofen were more likely to require a blood transfusion (OR 1.99, 95% CI: 1.42-2.79). In a subset of children receiving ketorolac, each additional day of ketorolac was associated with an increase odds of blood transfusion (OR 1.39, 95% CI: 1.30-1.49).

CONCLUSION

Perioperative ketorolac alone is not associated with an increased risk of significant bleeding in children undergoing appendectomy for perforated appendicitis. However, use of both ketorolac and ibuprofen during hospitalization was associated with increased risk of bleeding, although precise timing of administration of these medications was unable to be determined. Extended ketorolac use was also associated with increased risk of bleeding requiring blood transfusion.

Novel Quality Improvement Targets to Address Healthcare Encounters After Pediatric Appendectomy

INTRODUCTION

Pediatric appendicitis clinical practice guidelines (CPGs) do not typically address postdischarge healthcare encounters. This study aims to examine common indications for returns to the health system to identify novel quality improvement targets.

METHODS

This retrospective cohort study analyzed patients aged 3 to 18 y undergoing appendectomy at a single institution from July 1, 2019, to July 31, 2020. The primary outcome was physical postdischarge encounters comprising emergency department (ED) visits and hospital readmissions. Indications for each encounter were categorized and stratified by appendicitis type (i.e., simple, gangrenous, or perforated). Multivariable logistic regression models were used to estimate association between appendicitis category and postdischarge encounters.

RESULTS

Of 434 patients, 240 (55.3%) had simple appendicitis, 77 (17.7%) gangrenous, and 117 (29.9%) perforated appendicitis. Overall, 48 patients had at least one instance of an unplanned postdischarge encounter with a total of 56 unplanned ED presentations and 24 readmissions. Perforated patients were significantly more likely to experience postdischarge ED (odds ratio 2.55; 95% confidence interval 1.29-5.02) and readmission encounters (odds ratio 6.63; 95% confidence interval 2.28-19.28). Common indications for ED encounters included abdominal pain (n = 20) with 25.0% readmitted, abdominal pain and gastrointestinal symptoms (e.g., diarrhea, vomiting, distention) (n = 16) with 87.5% readmitted, and incision concerns (n = 6) with 16.7% readmitted. Common indications for readmissions included intraabdominal abscesses (n = 8) and small bowel obstruction (n = 4).

CONCLUSIONS

Assessing indications for postdischarge healthcare encounters enables identification of novel quality improvement targets, including proactively addressing incision concerns and abdominal pain.

Opioid reduction and elimination in pediatric surgical patients

INTRODUCTION

Opioid overuse is a national concern. Mitigation strategies include judicious prescribing and encouragement of non-opioid therapies. This quality improvement project aimed to identify physician opioid prescribing and patient usage patterns at a pediatric academic center.

METHODS

Patients who underwent same-day general, orthopedic, or plastic surgery procedures were contacted 7 - 28 days post-operatively. Inquiries were made about opioid usage, non-opioid strategies, and overall pain management satisfaction. A subset of general surgery patients not prescribed opioids was compared to those prescribed opioids.

RESULTS

Between August 2017 - May 2020, 558 surveys were obtained. There was a significant increase in the use of non-opioid therapies between 2017 and 2020 (83.5% vs 97%, p=0.04). Almost all patients' opioid prescriptions were filled; however, 78-98% had leftover opioids. Only 20-25% disposed the excess opioids. In subset analysis of general surgery patients, no inguinal hernia or orchiopexy patient who was discharged without opioids required opioids later. More non-opioid patients used other therapies (acetaminophen, heat (p=0.03)); however, pain management satisfaction was higher in the opioid group (99% vs 94%, p=0.01).

CONCLUSION

While our opioid prescribing has decreased, physicians are still prescribing more opioids than patients require. Further education on non-opioid pain therapies and proper disposal of opioids are needed.

Multi-Institutional Quality Improvement Project to Minimize Opioid Prescribing in Children after Appendectomy Using NSQIP-Pediatric

BACKGROUND

There is wide variation in opioid prescribing after appendectomy in children and adolescents, with recent increases noted in opioid-related pediatric deaths from prescription and illicit opioids. The goal of this project was to minimize opioid prescribing at the time of discharge for children undergoing appendectomy by using Quality Improvement (QI) methodology.

STUDY DESIGN

Children (18 years of age or less) who underwent appendectomy were evaluated from January to December 2019 using NSQIP-Pediatric at 10 children's hospitals within the Western Pediatric Surgery Research Consortium. Before project initiation, 5 hospitals did not routinely prescribe opioids after appendectomy (protocol). At the remaining 5 hospitals, prescribing was not standardized and varied by surgeon (no-protocol). A prospective multi-institutional QI project was used to minimize outpatient opioid prescriptions for children after appendectomy. The proportion of children at each hospital receiving an opioid prescription at discharge was compared for 6 months before and after the intervention using chi-square analysis.

RESULTS

Overall, 1,524 children who underwent appendectomy were evaluated from January to December 2019. After the QI intervention, overall opioid prescribing decreased from 18.2% to 4.0% (p < 0.001), with significant decreases in protocol hospitals (2.7% vs 0.8%, p = 0.038) and no-protocol hospitals (37.9% vs 8.8%, p < 0.001). The proportion of 30-day emergency room visits did not change after the QI intervention (8.9% vs 9.9%, p = 0.54) and mean postintervention pain management satisfaction scores were high.

CONCLUSION

Opioid prescribing can be minimized in children after appendectomy without increasing emergency room visits or decreasing patient satisfaction. Furthermore, NSQIP-Pediatric can be used as a platform for multi-institutional collaboration for successful implementation of QI projects.

Post-Procedural Opioid Prescribing in Children: A Survey of the American Academy of Pediatrics

INTRODUCTION

North America is in the midst of an opioid epidemic. The role of pediatric surgeons and other procedural specialists in this public health crisis remains unclear. There is likely considerable variation in the use of opioid and non-opioid analgesics, but the spectrum of practice is still uncertain.

METHODS

We performed an online survey in July 2018 of the 2086 pediatric surgeons and proceduralists who were active members in the American Academy of Pediatrics. The survey inquired about practice environment, use of opioid and non-opioid pain medications, and attitudes towards the opioid epidemic.

RESULTS

178 specialists completed the survey for a response rate of 8.5%. Most respondents utilize oral acetaminophen (86%) and ibuprofen (80%) after procedures >75% of the time. Self-reported opioid prescribing increases with age after both outpatient and inpatient procedures (P < 0.001). Pediatric general surgeons prescribe opioids less frequently than other specialists, particularly after inpatient procedures. The majority of respondents (81%) believe that the opioid epidemic is a major problem but only 31% indicated that they have a major role to play.

CONCLUSIONS

There is significant variation in opioid prescribing patterns as reported by pediatric surgeons and proceduralists. Guidelines are needed to standardize the use of non-opioid analgesics and decrease reliance on opioids for outpatient and inpatient procedures.

The impact of intravenous acetaminophen pricing on opioid utilization and outcomes for children with appendicitis

BACKGROUND

In 2014, the price of intravenous acetaminophen more than doubled. This study determined whether increased intravenous acetaminophen cost was associated with decreased utilization and increased opioid use for children undergoing appendectomy.

METHODS

A multicenter retrospective cohort study using the Pediatric Health Information System database between 2011 and 2017 was performed. Healthy children 2 to 18 years undergoing appendectomy at 46 children's hospitals in the United States were identified. Intravenous acetaminophen use, opioid use, and pharmacy costs were assessed. Multivariable mixed-effects modeling was used to determine the association between postoperative opioid use, intravenous acetaminophen use, and postoperative length-of-stay.

RESULTS

Overall, 110,019 children undergoing appendectomy were identified, with 22.5% (N = 24,777) receiving intravenous acetaminophen. Despite the 2014 price increase, intravenous acetaminophen use increased from 3% in 2011 to 40.1% in 2017 (P < .001), but at a significantly reduced rate. After 2014, adjusted median pharmacy charges decreased from $3,326.5 (interquartile range: $1,717.5-$6,710.8) to $3,264.1 (interquartile range: $1,782.8-$5,934.7, P < .001) for children who received intravenous acetaminophen. In 94,745 children staying ≥1 day after surgery, postoperative opioid use decreased from 73.6% in 2011 to 58.6% in 2017 (P < .001). Use of intravenous acetaminophen alone compared to opioids alone after surgery resulted in similar predicted mean postoperative length-of-stay.

CONCLUSION

In children undergoing appendectomy, intravenous acetaminophen use continued to rise, but at a slower rate after a price increase. Furthermore, adjusted pharmacy charges were lower for children receiving intravenous acetaminophen, possibly secondary to a concurrent decrease in postoperative opioid use. These findings suggest intravenous acetaminophen may be more broadly used regardless of perceived costs to minimize opioid use after surgery.

Barriers and Facilitators to Effective Pain Management by Parents After Pediatric Outpatient Surgery

INTRODUCTION

The purpose of this study was to describe the experience of postoperative pain management from the perspectives of parents and identify areas for improvement.

METHOD

Forty parents or legal guardians of children aged 5-18 years who underwent outpatient surgery at BC Children's Hospital were recruited. Qualitative semistructured interviews were conducted to explore participants' experiences with the discharge instructions and at-home pain management.

RESULTS

Overall, participants reported positive experiences with pain management. Facilitators in pain management communication included the combination of verbal and written instructions. Barriers to effective pain management included discrepancies in the information provided by different health care professionals and the experience of stress at the time of pain management communication.

DISCUSSION

The exploration of parent narratives highlighted the need for detailed information resources and patient-centered care surrounding pain management. The practical recommendations identified will inform future research and improve the quality of care for pediatric pain.
