Variation in postoperative narcotic prescribing after pediatric appendectomy

Cold Therapy for Pain Control in Pediatric Appendectomy Patients: A Randomized Controlled Trial

PURPOSE

Topical ice has been shown to reduce pain scores and opioid use in adults with midline abdominal incisions. This study was designed to evaluate the efficacy of a cold therapy system in children following laparoscopic appendectomy.

METHODS

Patients 7 years and older who underwent laparoscopic appendectomy at our institution from December 2021-September 2022 were eligible. Patients were randomized to standard pain therapy (control) or standard plus cold therapy (treatment) utilizing a modified ice machine system with cool abdominal pad postoperatively. Pain scores on the first 3 postoperative days (PODs), postoperative narcotic consumption, and patient satisfaction were analyzed.

RESULTS

Fifty-eight patients were randomized, 29 to each group. Average survey response rate was 74% in control and 89% in treatment patients. There was no significant difference in median pain scores or narcotic use between groups. Cold therapy contributed to subjective pain improvement in 71%, 74%, and 50% of respondents on PODs 1, 2, and 3 respectively.

CONCLUSION

A majority of patients reported cold therapy to be a helpful adjunct in pain control after appendectomy, though it did not reduce postoperative pain scores or narcotic use in our cohort - likely due to this population's naturally expedient recovery and low baseline narcotic requirement.

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.

A Novel Tool to Predict Postoperative Opioid Need after Laparoscopic Appendectomy in Children: A Step toward Evidence-Based Pain Management

BACKGROUND

 Optimizing postoperative pain treatment is essential to minimize morbidity, lower costs, and ensure patient and parent satisfaction. This study aims at identifying pre- and intraoperative parameters predicting opioid needs after laparoscopic appendectomy to enable timely and adequate postoperative pain control.

MATERIALS AND METHODS

 A retrospective analysis of patients treated with laparoscopic appendectomy for appendicitis between January 2018 and March 2019 was performed. Multiple logistic regression was applied to identify predictors of opioid demand.

RESULTS

 Based on our analysis, we developed a prediction tool for opioid requirements after laparoscopic appendectomies in children. The integrated parameters are: presence of turbid fluid, age, white-blood-cell count, symptom duration, and body temperature.

CONCLUSION

 We developed an algorithm-based predictor tool that has the potential to better anticipate postoperative pain and, thereby, optimize pain management following laparoscopic appendectomies in children. The proposed predictor tool will need validation through further prospective studies.

Unused opioid prescription prevalence after pediatric ambulatory surgery: a survey study

Background

Surgery is a risk factor for opioid initiation, persistent use, and subsequent misuse in pediatric patients. The objective of this study was to assess the rate of postoperative opioid prescribing and extent of unused opioid prescriptions on the first postoperative day after pediatric ambulatory surgery.

Methods

A telephone survey was administered on postoperative day 1 (POD1) to guardians of all pediatric patients who underwent ambulatory surgery at a single medical center. Participants were asked whether postoperative opioids were prescribed, and, if yes, whether they were currently taking them. Multivariable logistic regression was used to assess factors associated with postoperative opioid prescribing and unused opioids on POD1.

Results

Of 1344 pediatric patients who underwent ambulatory surgical procedures, 849 (63.1%) guardians responded to the survey. 275 (32.4%) were prescribed postoperative opioids, and 164 (59.6%) reported not taking opioids on POD1. The highest rates of unused opioid prescriptions were from orthopedic and plastic surgery services (28% and 29%, respectively). Governmental insurance status predicted having unused opioids (OR 0.59, CI 0.35–0.97).

Conclusions

Unused opioid prescriptions were prevalent in this pediatric ambulatory surgical population. Opportunities remain to streamline opioid prescribing in pediatric patients undergoing ambulatory surgical procedures.

Risk factors associated with recent opioid-related hospitalizations in children: a nationwide analysis

PURPOSE

Identifying at-risk children can provide a crucial opportunity for preventative measures to avoid opioid addiction. This study sought to determine at-risk pediatric patients that were previously hospitalized due to other causes prior to their opioid-related admission.

METHODS

The Nationwide Readmissions Database (2010-2014) was queried for children 1-18 years old with an opioid-related hospitalization. Previous admissions (up to 1 year prior) and associated diagnoses were compared. Results were weighted for national estimates.

RESULTS

51,349 opioid-related hospitalizations were identified with an overall in-hospital mortality of 0.8%. Seventeen percent had a previous admission during the same calendar year of which 44% had > 1 and 11% had ≥ 5 prior admissions. Only 4% of prior admissions occurred at a different hospital. Males and females were equally represented, and 82% were ≥ 13 years old. Only 16% of previously admitted patients underwent a major surgical procedure during a previous hospitalization. The most common concomitant diagnoses for patients with prior hospitalizations were drug abuse (37%), chronic pulmonary disease (18%), and depression (10%).

CONCLUSION

Opioid-related hospitalizations often occur among children with multiple recent admissions, usually to the same hospital. Most patients do not have a history of cancer or recent surgery to account for their opioid use.

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.

Impact of prescription drug monitoring program mandate on postoperative opioid prescriptions in children

PURPOSE

Prescription drug monitoring programs (PDMPs) have been established to combat the opioid epidemic, but there is no data on their efficacy in children. We hypothesized that a statewide PDMP mandate would be associated with fewer opioid prescriptions in pediatric surgical patients.

METHODS

Patients < 18 undergoing inguinal hernia repair, orchiopexy, orchiectomy, appendectomy, or cholecystectomy at a tertiary children's hospital were included. The primary outcome, discharge opioid prescription, was compared for 10 months pre-PDMP (n = 158) to 10 months post-PDMP (n = 228). Interrupted time series analysis was performed to determine the effect of the PDMP on opioid prescribing.

RESULTS

Over the 20-month study period, there was an overall decrease in the rate of opioid prescriptions per month (- 3.6% change, p < 0.001). On interrupted time series analysis, PDMP implementation was not associated with a significant decrease in the monthly rate of opioid prescriptions (1.27% change post-PDMP, p = 0.4). However, PDMP implementation was associated with a reduction in opioid prescriptions of greater than 5 days' supply (- 2.7% per month, p = 0.03).

CONCLUSION

Opioid prescriptions declined in pediatric surgical patients over the study time period. State-wide PDMP implementation was associated with a reduction in postoperative opioid prescriptions of more than 5 days' duration.

Pediatric surgeon opioid prescribing behavior: A survey of the American Pediatric Surgery Association membership

BACKGROUND

The opioid crisis has led to increasing numbers of overdose fatalities in teens and young adults. Surgery, as a common cause of acute pain in children, drives much of the opioid prescribing in pediatrics. Therefore, we sought to characterize opioid prescribing practices of pediatric surgeons by surveying members of the American Pediatric Surgery Association (APSA).

STUDY DESIGN

After receiving approval from our institutional review board, we sent an online survey to the entire APSA membership. The survey included four vignettes of common pediatric surgical procedures with questions regarding analgesic prescribing practices, the rationale for these practices, and knowledge about opioid risk mitigation.

RESULTS

Of 1127 APSA members contacted, 327 (29%) provided survey responses. For all vignettes, opioid prescribing was within standard ranges for 83% of respondents. Eighty-eight percent of respondents prescribed nonopioid pain medicine. Additionally, 25% reported routinely utilizing a prescription drug monitoring program, 64% did not tell patients how to dispose of opioids, and 37% did not know themselves how to dispose of leftover opioids.

CONCLUSIONS

Prescribing by APSA surgeons is largely within standard ranges, but improvement is needed, particularly regarding opioid disposal. Procedure-specific consensus guidelines for opioid prescribing and opioid risk mitigation strategies are warranted.

Children's Opioid Use at Home After Laparoscopic Appendectomy

BACKGROUND

To combat the opioid epidemic, prescribers need accurate information about pediatric home opioid requirements to manage acute pain after surgery. Current opioid use estimates come from retrospective surveys; this study used medication adherence technology (eCAP) to track home opioid use.

PURPOSE

To describe children's pain treatment at home after laparoscopic appendectomy, and to compare self-reported opioid analgesic use to eCAP data and counts of returned pills.

DESIGN

Prospective exploratory and descriptive study METHODS: A convenience sample of 96 patients, 10-17 years of age, from a single urban nonprofit children's hospital consented to self-report pain treatment in 14-day diaries and use eCAP to monitor prescribed opioid use at home after laparoscopic appendectomy.

RESULTS

Patients were prescribed 5-45 opioid-containing pills (mean ± standard deviation 15 ± 7.2). Of 749 opioid-containing pills prescribed to 49 patients who returned data, 689 pills were dispensed, 167.5 were used for the reason prescribed, 488 were returned to families for disposal, and 53.5 were missing. The majority of the 49 patients were opioid naïve (72%), Caucasian (64%), and male (56%), with a mean age of 14 years. Patients used 6.6 ± 6.3 opioid-containing pills by pill count and 5.6 ± 5.1 by self-report, a significant difference (p = .004). Unreported eCAP-enabled pill bottle openings typically occurred on weekends.

CONCLUSION

Medication adherence technology (eCAP) is a more rigorous method than self-report to estimate opioid needs and detect early opioid misuse. Additional rigorously designed studies of postoperative opioid use are needed to guide opioid prescribing.

Children's Pain at Home After Laparoscopic Appendectomy

BACKGROUND

Hospitalized children experience moderate-to-severe pain after laparoscopic appendectomy, but knowledge of children's pain experiences after discharge home is limited. Accurate pain assessments are needed to guide appropriate pain treatment.

AIMS

To describe children's pain at home after laparoscopic appendectomy.

DESIGN

Prospective exploratory and descriptive METHODS: A convenience sample of 100 patients, aged 10-17 years, who spoke or wrote in English or Spanish, volunteered to complete 14-day pain diaries at home after laparoscopic appendectomy. Visual analytic techniques were used to analyze patterns of pain experiences.

RESULTS

Diaries were returned by 45 patients/parents, the majority of whom were White (64%), male (56%), adolescents (mean age 14 years) with no previous surgical history (70%), and whose appendix was inflamed (87%) but not perforated. More than 50% reported severe pain (4 or 5 on a 0-5 scale) on the first full day home after laparoscopic appendectomy. On day 7, 40% reported pain and on day 14, 16% were still reporting pain. Only rarely were pain scores not clinically significantly lower 1 hour after pain treatment, regardless of treatment type (e.g., nondrug, nonopioid, opioid). Reported pain intensity steadily decreased over time as did frequency of recorded pain scores.

CONCLUSION

Adolescents experience severe pain at home after laparoscopic appendectomy and some experience pain for 7 to 14 days after hospital discharge. Visual analytics better represent the dynamics of pain experiences than measures of central tendency.

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

PURPOSE

We developed an algorithm to decrease opioid prescriptions for pediatric oncology patients at discharge following surgery, based on a retrospective analysis to decrease variability and over-prescribing. The aim of this study was to prospectively test the algorithm.

METHODS

Opioid-naïve patients undergoing surgery for tumor resection at a single institution were included. A prescribing algorithm was developed based on surgical approach, day of discharge, and inpatient opioid use. Prospectively collected data included outpatient opioid consumption and patient/family satisfaction. Total home dose prescribed was equal to that used in the 8 or 24 h, depending on length of stay and operative approach, prior to discharge, divided into 0.15 mg/kg doses.

RESULTS

The algorithm was used in 121 patients and correctly predicted outpatient opioid requirements for 102 patients (84.3%). For 15 (12.4%) patients, the algorithm over-estimated opioid need by an average of 0.38 OME/kg. Four (3.3%) patients required additional opioids. Using this algorithm, we decreased overall opioid prescriptions from 6.17 to 0.21 OME/kg (p < 0.001), and all but one patient/family reported being satisfied with post-operative pain control.

CONCLUSION

Using an algorithm based on inpatient opioid use, outpatient opioid needs can be accurately predicted, thereby reducing excess opioid prescriptions without detriment to patient satisfaction.

No pain is gain: A prospective evaluation of strict non-opioid pain control after pediatric appendectomy

INTRODUCTION

Opiates are often prescribed after pediatric operations despite safety concerns and lack of evidence confirming superiority compared to other pain control modalities. In this study, we use daily parental surveys to prospectively evaluate a strict non-opioid pain control strategy after laparoscopic appendectomy.

METHODS

After IRB approval, children who underwent laparoscopic appendectomy for nonperforated acute appendicitis were recruited to the study. For these patients, our standard practice is to provide instructions to administer alternating acetaminophen and ibuprofen over-the-counter (OTC) postoperatively, and no opiate prescriptions are written. Parents of enrolled children received a daily RedCap survey via text message or e-mail on postoperative days (POD) 1 through 5 to prospectively assess pain control and medication usage. Trends were compared across postoperative days.

RESULTS

One hundred twenty patients were enrolled in the study, and none received opiate prescriptions. Postoperative pain survey response rates were 54% on POD1, 47% on POD2, 35% on POD3, 34% on POD4, and 29% on POD5. Pain level was 4.7 ± 2.3 (out of 10) on POD1, and down-trended significantly each postoperative day to reach 0.7 ± 1.2 by POD5. On POD1, 85% of parents administered OTC medications, which reduced significantly to 14% by POD5. Parent-reported success rates to manage pain by OTC regimen were 85% on POD1, 94% on POD2, 91% on POD3, and 100% on POD4 and POD5.

CONCLUSION

Strict non-opioid pain control after appendectomy exhibits high performance based upon prospective parental surveys. This strategy should be implemented as standard of care and tested for application to other surgical conditions.

A Quality Improvement Intervention to Decrease Postoperative Opioid Prescriptions in Pediatric Oncology Patients

PURPOSE

This quality improvement initiative aimed to minimize opioid prescribing after oncologic pediatric surgery.

METHODS

Retrospective surgical data collected at a pediatric cancer hospital from July 2016 to June 2018 included hospitalization details, oral morphine equivalents prescribed, unplanned visits/calls because of pain, and parental/patient satisfaction with pain control. The quality improvement initiative promoted opioid prescription at discharge on the basis of prior inpatient requirements and education regarding nonopioid analgesia. Upon commencing this project in July 2018, we collected data prospectively.

RESULTS

The retrospective and the prospective cohorts included 271 and 99 patients, respectively. Mean (SD) oral morphine equivalents (mg/kg) prescribed upon discharge was significantly reduced in the prospective (0.75±1.34) versus retrospective cohorts (5.48±6.94, P<0.001). The unplanned visits/calls regarding pain were 23 (retrospective, 8.5%) and 2 (prospective, 2.0%). In total, 44 patients (44.4%) received an opioid prescription at discharge in the prospective cohort, significantly fewer than retrospective cohort (251, 92.6%, P<0.001), and used a mean of 34.3 of 159.8 (21.5%) doses dispensed. Length of stay was comparable (P=0.88) between cohorts. Prospective satisfaction rate was 96.2%, leaving 3 patients (3.8%) not satisfied with their pain control regimen.

CONCLUSIONS

Dramatic reduction of opioid prescriptions after oncologic surgery can be achieved without detriment to patient satisfaction or readmissions.

Eliminating Opiate Prescribing for Children after Non-Perforated Appendectomy

BACKGROUND

Opiates are the traditional treatment for postoperative pain. Recognition that increased availability of opiates in the community is associated with increased addiction has led to efforts to decrease postoperative opiate distribution. However, there are concerns that without opiates, pain relief might be inadequate.

STUDY DESIGN

We analyzed opiate prescriptions to children who had undergone appendectomy during 3 time periods: before intervention (July 2012 through February 2013), after opiate prescriptions were standardized and reduced (December 2016 through December 2017), and after opiate prescriptions were eliminated (January 2018 through December 2018). We determined how many opiate prescriptions had been written and how many had been filled in each time period. Patients were contacted by phone to identify their medication use and quality of pain management.

RESULTS

Pre-intervention, 75 children underwent appendectomy, and all received opiate prescriptions, with a mean of 15 doses of oxycodone prescribed per patient. After reduction, 208 children underwent appendectomy and 30% received opiate prescriptions, for a mean of 1.5 doses of oxycodone per patient. After elimination, 270 patients underwent appendectomy and 3 patients (1.1%) received opiate prescriptions, for a mean of 0.05 doses of oxycodone per patient. Patients contacted by phone expressed no pain relief issues and no patients needed opiates later.

CONCLUSIONS

Using a stepwise process, we have eliminated the use of opiates for postdischarge pain in children undergoing laparoscopic appendectomy. This intervention has resulted in the elimination of 4,035 doses of oxycodone from the community during the study period, while ensuring that postoperative pain control has been adequate.

An Evidence-Based Guideline Supporting Restricted Opioid Prescription after Pediatric Appendectomy

BACKGROUND/PURPOSE

Surgeon overprescription of opioids is a modifiable contributor to the opioid epidemic. No clear guidelines exist for prescribing opioids to younger patients after surgery. We sought to determine postoperative opioid needs in pediatric/young adult patients after laparoscopic appendectomy.

METHODS

Patients 5-20 years old who underwent laparoscopic appendectomy were included for study. All consented patients underwent chart review and were additionally called for an attempted interview. Caregivers were queried on analgesic use and adequacy of pain relief. The main outcome measures were: quantity of opioid used, desire for an opioid, presence of pain ≥4/10, and need for follow-up/call owing to pain. All opioids were converted into morphine milligram equivalents (MME).

RESULTS

Seventy-three patients qualified for the study, 49 of whom completed a postoperative telephone interview. Of the interviewees, 83% did not use or desire an opioid and reported pain <4/10 after discharge. Five patients used an opioid upon discharge, and the average MME consumed was 23 (equivalent to 3 pills of 5 mg oxycodone). No zero-opioid patients had unanticipated follow-up for pain concerns.

CONCLUSIONS

After hospital discharge following laparoscopic appendectomy, most patients have adequate analgesia without opioids. Opioid prescriptions should be offered sparingly and for no more than 25 MME.
