Persistent Opioid Use Following Pediatric Nonfatal Firearm Injury.

OBJECTIVE: Firearms are a major cause of pediatric injury. An analysis of opioid use following pediatric firearm injury has not previously been reported. Our objective was to determine the prevalence and factors associated with persistent opioid use among pediatric nonfatal firearm injury victims. METHODS: We performed a retrospective cohort study using 2015-18 claims data from the Merative MarketScan Multi-State Medicaid and Commercial Databases, utilizing International Classification of Diseases, Tenth Revision codes for firearm injury and National Drug Codes for opioids. Dispensed opioid claims were used as a proxy for opioid use. Opioid exposure was defined both dichotomously and continuously (by the total number of opioid days prescribed) in the 30 days following discharge from firearm injury index encounter. Persistent opioid use was defined as ≥1 opioid claim(s) in the 90 to 270 days following index encounter. Multivariable logistic regression analysis was performed to determine whether covariates of interest were associated with greater odds of persistent opioid use. RESULTS: Our cohort consisted of 2110 children who experienced nonfatal firearm injury (mean age 13.5, 80.9% male, 79.5% Medicaid) with 608 children (28.8%) exposed to opioids. Of patients exposed to opioids, 10.4% developed persistent opioid use. In adjusted analyses, each opioid day dispensed during the exposure period represented 5% greater odds of experiencing persistent opioid use. CONCLUSIONS: Clinicians caring for children injured by firearms should be aware of the risk of developing persistent opioid use and balance that risk with the need to sufficiently control pain.

Racial/Ethnic Patterns in Opioid Dispensing among Medicaid-Funded Young Children.

Racial differences in opioid dispensing for diseases of the respiratory system (RESP) and injury (INJURY) outpatient visits among patients ≤ 3 years old were examined. Outpatient claims data of South Carolina Medicaid children were analyzed over three three-year periods. The variable of interest was the triennial rate of dispensed opioid prescriptions per 1000 visits for RESP and INJURY diagnoses across racial/ethnic groups. Overall, dispensed opioid prescription rates related to RESP declined for all racial/ethnic categories. White children had the highest dispensing rate for RESP indications in the first period (5.6), followed by Black (4.5), and Hispanic (4.1). The likelihood of White children being prescribed opioids was higher than Blacks, and this was persistent over the studied time (rate ratios from 1.24 to 1.22, respectively). Overall opioid dispensing rates related to injury declined during the studied time. Hispanics had the highest dispensing rate for INJURY (20.1 to 14.8 to 16.1, respectively) followed by White (16.1 to 13.1 to 10.4, respectively). Relative differences in the dispensing rates across groups increased over time (Hispanics vs. White: rate ratios from 1.25 to 1.55, Hispanics vs. Black: from 1.52 to 2.24, and White vs. Black: from 1.24 to 1.44, respectively). There are considerable differences in the dispensing rates across racial/ethnic groups, especially in injury-related prescribing.

Annual Prevalence of Opioid Receipt by South Carolina Medicaid-Enrolled Children and Adolescents: 2000-2020.

Understanding patterns of opioid receipt by children and adolescents over time and understanding differences between age groups can help identify opportunities for future opioid stewardship. We conducted a retrospective cohort study, using South Carolina Medicaid data for children and adolescents 0-18 years old between 2000-2020, calculating the annual prevalence of opioid receipt for medical diagnoses in ambulatory settings. We examined differences in prevalence by calendar year, race/ethnicity, and by age group. The annual prevalence of opioid receipt for medical diagnoses changed significantly over the years studied, from 187.5 per 1000 in 2000 to 41.9 per 1000 in 2020 (Cochran-Armitage test for trend, p < 0.0001). In all calendar years, older ages were associated with greater prevalence of opioid receipt. Adjusted analyses (logistic regression) assessed calendar year differences in opioid receipt, controlling for age group, sex, and race/ethnicity. In the adjusted analyses, calendar year was inversely associated with opioid receipt (aOR 0.927, 95% CI 0.926-0.927). Males and older ages were more likely to receive opioids, while persons of Black race and Hispanic ethnicity had lower odds of receiving opioids. While opioid receipt declined among all age groups during 2000-2020, adolescents 12-18 had persistently higher annual prevalence of opioid receipt when compared to younger age groups.

Improving the Quality of Written Discharge Instructions: A Multisite Collaborative Project.

BACKGROUND AND OBJECTIVES: Written discharge instructions help to bridge hospital-to-home transitions for patients and families, though substantial variation in discharge instruction quality exists. We aimed to assess the association between participation in an Institute for Healthcare Improvement Virtual Breakthrough Series collaborative and the quality of pediatric written discharge instructions across 8 US hospitals. METHODS: We conducted a multicenter, interrupted time-series analysis of a medical records-based quality measure focused on written discharge instruction content (0-100 scale, higher scores reflect better quality). Data were from random samples of pediatric patients (N = 5739) discharged from participating hospitals between September 2015 and August 2016, and between December 2017 and January 2020. These periods consisted of 3 phases: 1. a 14-month precollaborative phase; 2. a 12-month quality improvement collaborative phase when hospitals implemented multiple rapid cycle tests of change and shared improvement strategies; and 3. a 12-month postcollaborative phase. Interrupted time-series models assessed the association between study phase and measure performance over time, stratified by baseline hospital performance, adjusting for seasonality and hospital fixed effects. RESULTS: Among hospitals with high baseline performance, measure scores increased during the quality improvement collaborative phase beyond the expected precollaborative trend (+0.7 points/month; 95% confidence interval, 0.4-1.0; P < .001). Among hospitals with low baseline performance, measure scores increased but at a lower rate than the expected precollaborative trend (-0.5 points/month; 95% confidence interval, -0.8 to -0.2; P < .01). CONCLUSIONS: Participation in this 8-hospital Institute for Healthcare Improvement Virtual Breakthrough Series collaborative was associated with improvement in the quality of written discharge instructions beyond precollaborative trends only for hospitals with high baseline performance.

Outpatient Opioid Dispensing Patterns for SC Medicaid Children 1-36 Months Old.

OBJECTIVES: We sought to identify the most common diagnostic categories linked to dispensed opioid prescriptions among children 1-36 months old and changes in patterns over the years 2000 to 2017. METHODS: This study used South Carolina's Medicaid claims data of pediatric dispensed outpatient opioid prescriptions between 2000 and 2017. The major opioid-related diagnostic category (indication) for each prescription was identified using visit primary diagnoses and the Clinical Classification System (AHRQ-CCS) software. The variables of interest were the rate of opioid prescriptions per 1,000 visits for each diagnostic category and the relative percentage of opioid prescriptions assigned to each category compared to all categories. RESULTS: Six major diagnostic categories were identified; Diseases of the respiratory system (RESP), Congenital anomalies (CONG), Injury (INJURY), Diseases of the nervous system and sense organs (NEURO), Diseases of the digestive system (GI), and Diseases of the genitourinary system (GU). The overall rate of dispensed opioid prescriptions per category declined significantly for four diagnostic categories throughout the study period, RESP by 15.13, INJURY by 8.49, NEURO by 7.33, and GI by 5.93. Two categories increased during the same time, CONG (by 9.47) and GU (by 6.98). RESP was the most prevalent category linked to a dispensed opioid prescription within 2010-2012 (almost 25%) but CONG was the most prevalent by 2014 (17.77%). CONCLUSIONS FOR PRACTICE: Among Medicaid children 1-36 months old, annual dispensed opioid prescription rates declined for most major diagnostic categories (RESP, INJURY, NEURO, and GI). Future studies should explore alternatives to current opioid dispensing practices for GU and CONG cases.

Opioid Use Patterns in a Statewide Adult Medicaid Population Undergoing Elective Lumbar Spine Surgery.

STUDY DESIGN: Retrospective administrative database review. OBJECTIVE: Analyze patterns of opioid use in patients undergoing lumbar surgery and determine associated risk factors in a Medicaid population. SUMMARY OF BACKGROUND DATA: Opioid use in patients undergoing surgery for degenerative lumbar spine conditions is prevalent and impacts outcomes. There is limited information defining the scope of this problem in Medicaid patients. MATERIALS AND METHODS: Longitudinal cohort study of adult South Carolina (SC) Medicaid patients undergoing lumbar surgery from 2014 to 2017. All patients had continuous SC Medicaid coverage for 15 consecutive months, including six months before and nine months following surgery. The primary outcome was a longitudinal assessment of postoperative opioid use to determine trajectories and group-based membership using latent modeling. Univariate and multivariable modeling was conducted to assess risk factors for group-based trajectory modeling and chronic opioid use (COU). RESULTS: A total of 1455 surgeries met inclusion criteria. Group-based trajectory model demonstrated patients fit into five groups; very low use (23.4%), rapid wean following surgery (18.8%), increasing use following surgery (12.9%), slow wean following surgery (12.6%) and sustained high use (32.2%). Variables predicting membership in high opioid use included preoperative opioid use, younger age, longer length of stay, concomitant medications, and readmissions. More than three quarter of patients were deemed COUs (76.4%). On bivariate analysis, patients with degenerative disk disease were more likely to be COUs (24.8% vs. 18.6%; P =0.0168), more likely to take opioids before surgery (88.5% vs. 61.9%; P <0.001) and received higher amounts of opioids during the 30 days following surgery (mean morphine milligram equivalents 59.6 vs. 25.1; P <0.001). CONCLUSIONS: Most SC Medicaid patients undergoing lumbar elective lumbar spine surgery were using opioids preoperatively and continued long-term use postoperatively at a higher rate than previously reported databases. Preoperative and perioperative intake, degenerative disk disease, multiple prescribers, depression, and concomitant medications were significant risk factors.

Surgical prescription opioid trajectories among state Medicaid enrollees.

OBJECTIVE: The objective of this study was to evaluate opioid use trajectories among a sample of 10,138 Medicaid patients receiving one of six index surgeries: lumbar spine, total knee arthroplasty, cholecystectomy, appendectomy, colon resection, and tonsillectomy. DESIGN: Retrospective cohort. SETTING: Administrative claims data. PATIENTS AND PARTICIPANTS: Patients, aged 13 years and older, with 15-month continuous Medicaid eligibility surrounding index surgery, were selected from single-state Medicaid medical and pharmacy claims data for surgeries performed between 2014 and 2017. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Baseline comorbidities and presurgery opioid use were assessed in the 6 months prior to admission, and patients' opioid use was followed for 9 months post-discharge. Generalized linear model with log link and Poisson distribution was used to determine risk of chronic opioid use for all risk factors. Group-based trajectory models identified groups of patients with similar opioid use trajectories over the 15-month study period. RESULTS: More than one in three (37.7 percent) patients were post-surgery chronic opioid users, defined as the dichotomous outcome of filling an opioid prescription 90 or more days after surgery. Key variables associated with chronic post-surgery opioid use include presurgery opioid use, 30-day post-surgery opioid use, and comorbidities. Latent trajectory modeling grouped patients into six distinct opioid use trajectories. Associates of trajectory group membership are reported. CONCLUSIONS: Findings support the importance of surgeons setting realistic patient expectations for post-surgical opioid use, as well as the importance of coordination of post-surgical care among patients failing to fully taper off opioids within 1-3 months of surgery.

Collaborative to Increase Lethal Means Counseling for Caregivers of Youth With Suicidality.

BACKGROUND: The number of youth presenting to hospitals with suicidality and/or self-harm has increased substantially in recent years. We implemented a multihospital quality improvement (QI) collaborative from February 1, 2018 to January 31, 2019, aiming for an absolute increase in hospitals' mean rate of caregiver lethal means counseling (LMC) of 10 percentage points (from a baseline mean performance of 68% to 78%) by the end of the collaborative, and to evaluate the effectiveness of the collaborative on LMC, adjusting for secular trends. METHODS: This 8 hospital collaborative used a structured process of alternating learning sessions and action periods to improve LMC across hospitals. Electronic medical record documentation of caregiver LMC was evaluated during 3 phases: precollaborative, active QI collaborative, and postcollaborative. We used statistical process control to evaluate changes in LMC monthly. Following collaborative completion, interrupted time series analyses were used to evaluate changes in the level and trend and slope of LMC, adjusting for covariates. RESULTS: In the study, 4208 children and adolescents were included-1314 (31.2%) precollaborative, 1335 (31.7%) during the active QI collaborative, and 1559 (37.0%) postcollaborative. Statistical process control analyses demonstrated that LMC increased from a hospital-level mean of 68% precollaborative to 75% (February 2018) and then 86% (October 2018) during the collaborative. In interrupted time series analyses, there were no significant differences in LMC during and following the collaborative beyond those expected based on pre-collaborative trends. CONCLUSIONS: LMC increased during the collaborative, but the increase did not exceed expected trends. Interventions developed by participating hospitals may be beneficial to others aiming to improve LMC for caregivers of hospitalized youth with suicidality.

New chronic opioid use in Medicaid patients following cholecystectomy.

Background: Commercial insurance data show that chronic opioid use in opioid-naive patients occurs in 1.5% to 8% of patients undergoing surgical procedures, but little is known about patients with Medicaid. Methods: Opioid prescription data and medical coding data from 4,788 Medicaid patients who underwent cholecystectomy were analyzed to determine opioid use patterns. Results: A total of 54.4% of patients received opioids prior to surgery, and 38.8% continued to fill opioid prescriptions chronically; 27.1% of opioid-naive patients continued to get opioids chronically. Patients who received ≥ 50 MME/d had nearly 8 times the odds of chronic opioid use. Each additional opioid prescription filled within 30 days was associated with increased odds of chronic use (odds ratio: 1.71). Conclusion: Opioid prescriptions are common prior to cholecystectomy in Medicaid patients, and 38.8% of patients continue to receive opioid prescriptions well after surgical recovery. Even 27.1% of opioid-naive patients continued to receive opioid prescriptions chronically.

Incidence and patterns of persistent opioid use in children following appendectomy.

BACKGROUND: The past 5 years have witnessed a concerted national effort to assuage the rising tide of the opioid misuse in our country. Surgical procedures often serve as the initial exposure of children to opioids, however the trajectory of use following these exposures remains unclear. We hypothesized that opioid exposure following appendectomy would increase the risk of persistent opioid use among publicly insured children. STUDY DESIGN: A retrospective longitudinal cohort study was conducted on South Carolina Medicaid enrollees who underwent appendectomy between January 2014 and December 2017 using administrative claims data. The primary outcome was chronic opioid use. Generalized linear models and finite mixture models were employed in analysis. RESULTS: 1789 Medicaid pediatric patients underwent appendectomy and met inclusion criteria. The mean age was 11.1 years and 40.6% were female. Most patients (94.6%) did not receive opioids prior to surgery. Opioid prescribing ≥90 days after surgery (chronic opioid use) occurred in 127 (7.1%) patients, of which 102 (80.3%) had no opioid use in the preexposure period. Risk factors for chronic opioid use included non-naïve opioid status, re-hospitalization more than 30 days following surgery, multiple opioid prescribers, age, and multiple antidepressants/antipsychotic prescriptions. Group-based trajectory analysis demonstrated four distinct post-surgical opioid use patterns: no opioid use (91.3%), later use (6.7%), slow wean (1.9%), and higher use throughout (0.4%). CONCLUSION: Opioid exposure after appendectomy may serve as a priming event for persistent opioid use in some children. Eighty percent of children who developed post-surgical persistent opioid use had not received opioids in the 90 days leading up to surgery. Several mutable and immutable factors were identified to target future efforts toward opioid minimization in this at-risk patient population. LEVEL OF EVIDENCE: III.

Development and Testing of an Emergency Department Quality Measure for Pediatric Suicidal Ideation and Self-Harm.

OBJECTIVE: To develop and test a new quality measure assessing timeliness of follow-up mental health care for youth presenting to the emergency department (ED) with suicidal ideation or self-harm. METHODS: Based on a conceptual framework, evidence review, and a modified Delphi process, we developed a quality measure assessing whether youth 5 to 17 years old evaluated for suicidal ideation or self-harm in the ED and discharged to home had a follow-up mental health care visit within 7 days. The measure was tested in 4 geographically dispersed states (California, Pennsylvania, South Carolina, Tennessee) using Medicaid administrative data. We examined measure feasibility of implementation, variation, reliability, and validity. To test validity, adjusted regression models examined associations between quality measure scores and subsequent all-cause and same-cause hospital readmissions/ED return visits. RESULTS: Overall, there were 16,486 eligible ED visits between September 1, 2014 and July 31, 2016; 53.5% of eligible ED visits had an associated mental health care follow-up visit within 7 days. Measure scores varied by state, ranging from 26.3% to 66.5%, and by youth characteristics: visits by youth who were non-White, male, and living in an urban area were significantly less likely to be associated with a follow-up visit within 7 days. Better quality measure performance was not associated with decreased reutilization. CONCLUSIONS: This new ED quality measure may be useful for monitoring and improving the quality of care for this vulnerable population; however, future work is needed to establish the measure's predictive validity using more prevalent outcomes such as recurrence of suicidal ideation or deliberate self-harm.

Dispensed Opioid Prescription Patterns, by Racial/Ethnic Groups, Among South Carolina Medicaid-Funded Children Experiencing Limb Fracture Injuries.

OBJECTIVE: To examine dispensed opioid prescription patterns for limb fractures across racial/ethnic groups in a pediatric population. METHODS: We used South Carolina's Medicaid claims data 2000 to 2018 for pediatric limb fracture cases (under age 19) discharged from the emergency department. The key independent variable was the child's race/ethnicity. The outcomes were: 1) whether the patient had a dispensed opioid prescription; and 2) whether dispensed opioid supply was longer than 5 days among cases with any dispensed opioid prescriptions. Logistic regression models were used to test the association between race/ethnicity and the outcomes. Covariates included age-at-service, gender, service year, and having multiple fracture injuries. RESULTS: Compared with non-Hispanic White cases (NHW), the odds of receiving dispensed opioid prescriptions were lower for cases of non-Hispanic Black (NHB) (OR = 0.73; 95% confidence interval [CI]: 0.71, 0.75), Asian (OR = 0.69; CI: 0.53, 0.90), Other/Unknown (OR = 0.86; CI: 0.80, 0.92), and Hispanic (OR = 0.84; CI: 0.79, 0.90) race/ethnicity. The odds of receiving >5 days of dispensed opioid prescription supply did not differ significantly among race/ethnic categories. CONCLUSIONS: Our study confirms previous findings that as compared to NHW, the NHB children were less likely to receive dispensed opioid prescriptions. Also, it reveals that the different minority race/ethnic groups are not homogenous in their likelihoods of receiving dispensed opioid prescriptions after a limb fracture compared to NHW, findings underreported in previous studies. Children in the Other/Unknown race/ethnicity category have prescribing patterns different from those of other minority race/ethnic groups and should be analyzed separately.

High-risk opioid analgesic dispensing to adolescents 12-18 years old in South Carolina: 2010-2017.

PURPOSE: To evaluate "high-risk" opioid dispensing to adolescents, including daily morphine milligram equivalents (MME) above recommended amounts, the percentage of extended-release opioid prescriptions dispensed to opioid-naïve adolescents, and concurrent use of opioids and benzodiazepines, and to evaluate changes in those rates over time. METHODS: Retrospective cohort study of one state's prescription drug monitoring program data (2010-2017), evaluating adolescents 12-18 years old dispensed opioid analgesic prescriptions. Outcomes of interest were the quarterly frequencies of the high-risk measures. We utilized generalized linear regression to determine whether the rate of the outcomes changed over time. RESULTS: The quarterly percentage of adolescents ages 12-18 years old dispensed an opioid who received ≥90 daily MME declined from 4.1% in the first quarter (Q1) of 2010 to 3.4% in the final quarter (Q4) of 2017 (p < 0.0001). The frequency of adolescents dispensed ≥50 daily MME changed little over time. In 2010, the percentage of adolescents receiving an extended-release opioid who were opioid naïve was 60.7%, declining to 50.6% by Q4 of 2017 (p > 0.10 overall change 2010-2017). The percentage of adolescent opioid days overlapping with benzodiazepine days was 1.6% in Q1 of 2010, declining to 1.1% by Q4 of 2017 (p < 0.001). CONCLUSIONS: Among persons 12-18 years old dispensed an opioid analgesic, receipt of ≥90 daily MME declined during the years 2010-2017, as did the percentage of adolescent opioid days that overlapped with benzodiazepines. More than half of the individuals who received extended-release opioid analgesics were identified as opioid naïve and, counter to guidelines, received products intended for opioid-tolerant individuals.

Quality of Care for Youth Hospitalized for Suicidal Ideation and Self-Harm.

OBJECTIVE: To examine performance on quality measures for pediatric inpatient suicidal ideation/self-harm care, and whether performance is associated with reutilization. METHODS: Retrospective observational 8 hospital study of patients [N = 1090] aged 5 to 17 years hospitalized for suicidal ideation/self-harm between 9/1/14 and 8/31/16. Two medical records-based quality measures assessing suicidal ideation/self-harm care were evaluated, one on counseling caregivers regarding restricting access to lethal means and the other on communication between inpatient and outpatient providers regarding the follow-up plan. Multivariable logistic regression assessed associations between quality measure scores and 1) hospital site, 2) patient demographics, and 3) 30-day emergency department return visits and inpatient readmissions. RESULTS: Medical record documentation revealed that, depending on hospital site, 17% to 98% of caregivers received lethal means restriction counseling (mean 70%); inpatient-to-outpatient provider communication was documented in 0% to 51% of cases (mean 16%). The odds of documenting receipt of lethal means restriction counseling was higher for caregivers of female patients compared to caregivers of male patients (adjusted odds ratio [aOR] 1.51, 95% confidence interval [CI], 1.07-2.14). The odds of documenting inpatient-to-outpatient provider follow-up plan communication was lower for Black patients compared to White patients (aOR 0.45, 95% CI, 0.24-0.84). All-cause 30-day readmission was lower for patients with documented caregiver receipt of lethal means restriction counseling (aOR 0.48, 95% CI, 0.28-0.83). CONCLUSIONS: This study revealed disparities and deficits in the quality of care received by youth with suicidal ideation/self-harm. Providing caregivers lethal means restriction counseling prior to discharge may help to prevent readmission.

Trends in Dispensed Opioid Analgesic Prescriptions to Children in South Carolina: 2010-2017.

BACKGROUND AND OBJECTIVES: Despite published declines in opioid prescribing and dispensing to children in the past decade, in few studies have researchers evaluated all children in 1 state or examined changes in mean daily opioid dispensed. In this study, we evaluated changes in the rate of dispensed opioid analgesics and the mean daily opioid dispensed to persons 0 to 18 years old in 1 state over an 8-year period. METHODS: We identified opioid analgesics dispensed to children 0 to 18 years old between 2010 and 2017 using South Carolina prescription drug monitoring program data. We used generalized linear regression analyses to examine changes over time in the following: (1) rate of dispensed opioid prescriptions and (2) mean daily morphine milligram equivalents (MMEs) per prescription. RESULTS: From the first quarter of 2010 to the end of the fourth quarter of 2017, the quarterly rate of opioids dispensed decreased from 18.68 prescriptions per 1000 state residents to 12.03 per 1000 residents (P < .0001). The largest declines were among the oldest individuals, such as the 41.2% decline among 18-year-olds. From 2010 through 2017, the mean daily MME dispensed declined by 7.6%, from 40.7 MMEs per day in 2010 to 37.6 MMEs per day in 2017 (P < .0001), but the decrease was limited to children 0 to 9 years old. CONCLUSIONS: The rate of opioid analgesic prescriptions dispensed to children 0 to 18 years old in South Carolina declined by 35.6% over the years 2010-2017; however, the MME dispensed per day declined minimally, suggesting that more can be done to improve opioid prescribing and dispensing.

Patterns of dispensed opioids after tonsillectomy in children and adolescents in South Carolina, United States, 2010-2017.

OBJECTIVES: Tonsillectomy (with or without adenoidectomy) is a common pediatric surgical procedure requiring post-operative analgesia. Because of the respiratory depression effects of opioids, clinicians strive to limit the use of these drugs for analgesia post-tonsillectomy. The objective of this study was to identify demographic and medication use patterns predictive of persistent opioid dispensing (as a proxy for opioid use) to pediatric patients post-tonsillectomy. PATIENTS AND METHODS: Retrospective cohort of South Carolina (USA) Medicaid-insured children and adolescents 0-18 years old without malignancy who had tonsillectomy in 2014-2017. We evaluated opioid dispensing pre-surgery and in the 30 days exposure period after hospital discharge. The main outcome, persistent opioid dispensing, was defined as any subject dispensed ≥1 opioid prescription 90-270 days after discharge. Group-based trajectory analyses described post-procedure opioid dispensing trajectories. RESULTS: There were 11,578 subjects representing 12,063 tonsillectomy procedures. Few (3.5%) procedures were followed by persistent opioid dispensing. Any opioid dispensing during the exposure period was associated with an increased odds of persistent opioid dispensing status during the follow up period (OR 1.51 for 1-6 days of exposure and OR 1.65 for 7-30 days of opioid exposure), as was pre-procedure opioid dispensing, having >1 tonsillectomy procedure, and having complex chronic medical conditions. Group-based trajectory analyses identified 4 distinct patterns of post-discharge opioid dispensing. CONCLUSIONS: Any opioid dispensing during the 30 days after tonsillectomy increased the odds of persistent opioid dispensing by > 50%. Multivariable and group-based trajectory analyses identified patient and procedure variables that correlate with persistent opioid dispensing, primarily driven by groups receiving pre-tonsillectomy opioids and a second group who experienced multiple episodes of tonsillectomy.

Opioids or Steroids for Pneumonia or Sinusitis.

OBJECTIVES: To compare the frequency of opioid and corticosteroid prescriptions dispensed for children with pneumonia or sinusitis visits on the basis of location of care. METHODS: We evaluated 2016 South Carolina Medicaid claims data for 5 to 18 years olds with pneumonia or sinusitis. Visits were associated with 1 of 3 locations: the emergency department (ED), urgent care, or the ambulatory setting. RESULTS: Inclusion criteria were met by 31 838 children. Pneumonia visits were more often linked to an opioid prescription in the ED (34 of 542 [6.3%]) than in ambulatory settings (24 of 1590 [1.5%]; P ≤ .0001) and were more frequently linked to a steroid prescription in the ED (106 of 542 [19.6%]) than in ambulatory settings (196 of 1590 [12.3%]; P ≤ .0001). Sinusitis visits were more often linked to an opioid prescription in the ED (202 of 2705 [7.5%]) than in ambulatory settings (568 of 26 866 [2.1%]; P ≤ .0001) and were more frequently linked to a steroid prescription in the ED (510 of 2705 [18.9%]) than in ambulatory settings (1922 of 26 866 [7.2%]; P ≤ .0001). In logistic regression for children with pneumonia, the ED setting was associated with increased odds of receiving an opioid (adjusted odds ratio [aOR] 4.69) or steroid (aOR 1.67). Similarly, patients with sinusitis were more likely to be prescribed opioids (aOR 4.02) or steroids (aOR 3.05) in the ED than in ambulatory sites. CONCLUSIONS: School-aged children received opioid and steroid prescriptions for pneumonia or sinusitis at a higher frequency in the ED versus the ambulatory setting.

Sensitivity of Clinical Pediatric Obesity Diagnosis Documented in Electronic Health Records.

Objective. This study tested the sensitivity of obesity diagnosis in electronic health records (EHRs) using body mass index (BMI) classification and identified variables associated with obesity diagnosis. Methods. Eligible children aged 2 to 18 years had a calculable BMI in 2017 and had at least 1 visit in 2016 and 2017. Sensitivity of clinical obesity diagnosis compared with children's BMI percentile was calculated. Logistic regression was performed to determine variables associated with obesity diagnosis. Results. Analyses included 31 059 children with BMI at or above 95th percentile. Sensitivity of clinical obesity diagnosis was 35.81%. Clinical obesity diagnosis was more likely if the child had a well visit, had Medicaid insurance, was female, Hispanic or Black, had a chronic disease diagnosis, and saw a provider in a practice in an urban area or with academic affiliation. Conclusion. Sensitivity of clinical obesity diagnosis in EHR is low. Clinical obesity diagnosis is associated with nonmodifiable child-specific factors but also modifiable practice-specific factors.

Age- and Sex-Related Differences in Nonfatal Dog Bite Injuries Among Persons Aged 0-19 Treated in Hospital Emergency Departments, United States, 2001-2017.

OBJECTIVE: No studies using national data have evaluated changes in nonfatal dog bite injuries among children, adolescents, and young adults during the past 2 decades. We examined estimates of annual nonfatal dog bite injuries among persons aged 0-19 treated in US emergency departments (EDs) from 2001 through 2017. METHODS: We examined data from the Web-based Injury Statistics Query and Reporting System to compare estimates of the annual rates of nonfatal dog bite injuries in EDs among all persons aged 0-19, by age group (0-4, 5-9, 10-14, and 15-19), and by sex. We determined significance by comparing 95% confidence intervals (CIs), and we standardized rate calculations to the year 2000 population. RESULTS: During 2001-2017, an estimated 2 406 109 (95% CI, 2 102 643-2 709 573) persons aged 0-19 were treated in EDs for nonfatal dog bite injuries (age-adjusted rate of 173.1 per 100 000 persons aged 0-19). The estimated number of nonfatal dog bite injuries declined significantly, from 181 090 (95% CI, 158 315-203 864) in 2001 to 118 800 (95% CI, 97 933-139 667) in 2017. The highest rate was among children aged 5-9. Male children, adolescents, and young adults were significantly more likely than female children, adolescents, and young adults to be treated in the ED for nonfatal dog bite injuries, driven by male-female differences in children and adolescents aged 5-14. CONCLUSIONS: Although the estimated number of nonfatal dog bite injuries among persons aged 0-19 declined significantly in the past 2 decades, additional regulatory and educational efforts specific to age and sex may lead to further reductions in nonfatal dog bite injuries.

Understanding the Constipation Conundrum: Predictors of Obtaining an Abdominal Radiograph During the Emergency Department Evaluation of Pediatric Constipation.

OBJECTIVES: Many children with constipation who are evaluated in emergency departments (EDs) receive an abdominal radiograph (AR) despite evidence-based guidelines discouraging imaging. The objectives of this study were to identify predictors associated with obtaining an AR and to determine if ARs were associated with a longer length of stay (LOS) among children with constipation evaluated in the ED. METHODS: A review of billing and electronic health records was conducted in an academic pediatric ED for children ages 0 to 17 years who had a primary discharge diagnosis of constipation from July 2013 to June 2014. Logistic regression was used to identify predictors for obtaining an AR. Differences in mean LOS were analyzed using linear regression. RESULTS: In total, 326 children met inclusion criteria, and 60% of the children received an AR. In logistic regression, significant predictors included age (odds ratio [OR] = 1.1/year of age, P = 0.004), presenting with abdominal pain as chief complaint compared with constipation (OR = 4.4, P < 0.0001), and history of emesis (OR = 2.8, P = 0.001) after controlling for provider type and previous constipation medication use. In linear regression, the adjusted mean LOS for those with an AR was 163 minutes compared with 117 minutes for those without after controlling for age, provider type, and history of constipation medication use (P < 0.0001). CONCLUSIONS: Abdominal radiographs were used frequently in the ED diagnosis and management of constipation, particularly in older children and those with abdominal pain and emesis. Abdominal radiographs were associated with increased LOS.
