First Opioid Prescription and Subsequent High-Risk Opioid Use: a National Study of Privately Insured and Medicare Advantage Adults.

ABSTRACT: BACKGROUND:National guidelines make recommendations regarding the initial opioid prescriptions, but most of the supporting evidence is from the initial episode of care, not the first prescription. OBJECTIVE:To examine associations between features of the first opioid prescription and high-risk opioid use in the 18 months following the first prescription. DESIGN:Retrospective cohort study using data from a large commercial insurance claims database for 2011-2014 to identify individuals with no recent use of opioids and follow them for 18 months after the first opioid prescription. PARTICIPANTS:Privately insured patients aged 18-64 and Medicare Advantage patients aged 65 or older who filled a first opioid prescription between 07/01/2011 and 06/30/2013. MAIN OUTCOMES AND MEASURES:High-risk opioid use was measured by having (1) opioid prescriptions overlapping for 7 days or more, (2) opioid and benzodiazepine prescriptions overlapping for 7 days or more, (3) three or more prescribers of opioids, and (4) a daily dosage exceeding 120 morphine milligram equivalents, in each of the six quarters following the first prescription. KEY RESULTS:All three features of the first prescription were strongly associated with high-risk use. For example, among privately insured patients, receiving a long- (vs. short-) acting first opioid was associated with a 16.9-percentage-point increase (95% CI, 14.3-19.5), a daily MME of 50 or more (vs. less than 30) was associated with a 12.5-percentage-point increase (95% CI, 12.1-12.9), and a supply exceeding 7 days (vs. 3 or fewer days) was associated with a 4.8-percentage-point increase (95% CI, 4.5-5.2), in the probability of having a daily dosage of 120 MMEs or more in the long term, compared to a sample mean of 4.2%. Results for the Medicare Advantage patients were similar. CONCLUSIONS:Long-acting formulation, high daily dosage, and longer duration of the first opioid prescription were each associated with increased high-risk use of opioids in the long term.

Project description:IntroductionBenzodiazepines are commonly prescribed in the U.S. but entail safety concerns, including dependency. In pediatrics, many indications lack trial data. Authors aimed to describe youth initiating prescription benzodiazepine treatment, identify potential indications and prescribing concerns, estimate the duration of treatment by potential indication, and identify factors that predict long-term use.MethodsThe study cohort included children (aged 3-12 years) and adolescents (aged 13-17 years) initiating prescription benzodiazepine treatment (≥3 days' supply) from January 2010 to September 2015 in a U.S. commercial claims database. Potential indications included selected ICD-9-CM diagnoses (≤30 days prior). Long-term (≥6 months) benzodiazepine treatment was estimated with Kaplan-Meier estimation and modified Poisson regression identified independent predictors of long-term benzodiazepine treatment (analysis completed in 2018).ResultsOf 24,504 children and 61,046 adolescents initiating benzodiazepines, 62% of the children and 68% of the adolescents had a potential indication. Anxiety disorders were the most common indication, with mental health indications more common among adolescents (45%) than children (23%) and epilepsy and movement disorders higher in children. Recent opioid prescriptions were common before benzodiazepine initiation (children, 22%; adolescents, 21%). Six percent of the initiators became long-term benzodiazepine users. Potential indication, provider contact, psychotropic medication, and chronic conditions independently predicted long-term benzodiazepine treatment in adolescents and children.ConclusionsU.S. children and adolescents are prescribed benzodiazepines for various mental health and other medical conditions, many lacking evidence of pediatric efficacy. Long-term benzodiazepine treatment, concurrent opioid prescriptions, psychotropic use, and prior substance use disorder diagnoses suggest safety risks among some youth prescribed benzodiazepines.

Project description:ObjectiveTo describe trends in the rate and daily dose of opioids used among commercial and Medicare Advantage beneficiaries from 2007 to 2016.DesignRetrospective cohort study of administrative claims data.SettingNational database of medical and pharmacy claims for commercially insured and Medicare Advantage beneficiaries in the United States.Participants48 million individuals with any period of insurance coverage between 1 January 2007 and 31 December 2016, including commercial beneficiaries, Medicare Advantage beneficiaries aged 65 years and over, and Medicare Advantage beneficiaries under age 65 years (eligible owing to permanent disability).Main endpointsProportion of beneficiaries with any opioid prescription per quarter, average daily dose in milligram morphine equivalents (MME), and proportion of opioid use episodes that represented long term use.ResultsAcross all years of the study, annual opioid use prevalence was 14% for commercial beneficiaries, 26% for aged Medicare beneficiaries, and 52% for disabled Medicare beneficiaries. In the commercial beneficiary group, quarterly prevalence of opioid use changed little, starting and ending the study period at 6%; the average daily dose of 17 MME remained unchanged since 2011. For aged Medicare beneficiaries, quarterly use prevalence was also relatively stable, ranging from 11% at the beginning of the study period to 14% at the end. Disabled Medicare beneficiaries had the highest rates of opioid use, the highest rate of long term use, and the largest average daily doses. In this group, both quarterly use rates (39%) and average daily dose (56 MME) were higher at the end of 2016 than the low points observed in 2007 for each endpoint (26% prevalence and 53 MME).ConclusionsOpioid use rates were high during the study period of 2007-16, with the highest rates in disabled Medicare beneficiaries versus aged Medicare beneficiaries and commercial beneficiaries. Opioid use and average daily dose have not substantially declined from their peaks, despite increased attention to opioid abuse and awareness of their risks.

Project description:ImportanceAlthough prescription opioids are the most common way adolescents and young adults initiate opioid use, many studies examine population-level risks following the first opioid prescription. There is currently a lack of understanding regarding how patterns of opioid prescribing following the first opioid exposure may be associated with long-term risks.ObjectiveTo identify distinct patterns of opioid prescribing following the first prescription using group-based trajectory modeling and examine the patient-, clinician-, and prescription-level factors that may be associated with trajectory membership during the first year.Design, setting, and participantsThis cohort study examined Pennsylvania Medicaid enrollees' claims data from 2010 through 2016. Participants were aged 10 to 21 years at time of first opioid prescription. Data analysis was performed in March 2020.Main outcomes and measuresThis study used group-based trajectory modeling and defined trajectory status by opioid fill.ResultsAmong the 189 477 youths who received an initial opioid prescription, 107 562 were female (56.8%), 81 915 were non-Latinx White (59.6%), and the median age was 16.9 (interquartile range [IQR], 14.6-18.8) years. During the subsequent year, 47 477 (25.1%) received at least one additional prescription. Among the models considered, the 2-group trajectory model had the best fit. Of those in the high-risk trajectory, 65.3% (n = 901) filled opioid prescriptions at month 12, in contrast to 13.1% (n = 6031) in the low-risk trajectory. Median age among the high-risk trajectory was 19.0 years (IQR, 17.1-20.0 years) compared with the low-risk trajectory (17.8 years [IQR, 15.8-19.4 years]). The high-risk trajectory received more potent prescriptions compared with the low-risk trajectory (median dosage of the index month for high-risk trajectory group: 10.0 MME/d [IQR, 5.0-21.2 MME/d] vs the low-risk trajectory group: 4.7 MME/d [IQR, 2.5-7.8 MME/d]; P < .001). The trajectories showed persistent differences with more youths in the high-risk trajectory going on to receive a diagnosis of opioid use disorder (30.0%; n = 412) compared with the low-risk group (10.1%; n = 4638) (P < .001).Conclusions and relevanceThis study's results identified 2 trajectories associated with elevated risk for persistent opioid receipt within 12 months following first opioid prescription. The high-risk trajectory was characterized by older age at time of first prescription, and longer and more potent first prescriptions. These findings suggest even short and low-dose opioid prescriptions can be associated with risks of persistent use for youths.

Project description:Background and aimsNon-invasive laboratory-based fibrosis indices have been proposed as a tool for population-based screening for advanced fibrosis. We aimed to examine the performance of fibrosis indices at the time of and prior to cirrhosis diagnosis.MethodsWe included adult patients with cirrhosis diagnosis codes in a privately insured database (Optum) from 2010-2018 with 1:4 birth year-matched controls without cirrhosis diagnosis codes. We analyzed aspartate aminotransferase-to-platelet ratio index (APRI), and fibrosis-4 index (FIB-4) up to 30 months prior to the entry of cirrhosis diagnosis codes. Cut-offs of <1 and ≥2 were used for APRI and <1.3 and ≥2.67 were used for FIB-4.ResultsWe included 10,650 patients with cirrhosis (median age 62 years), who were predominantly white (57.8%) and male (51.9%). The most common etiologies of cirrhosis were non-alcoholic steatohepatitis (23.8%), hepatitis C (23.0%), and alcohol-related liver disease (20.5%). At the time of cirrhosis diagnosis (±3 months), 9.3% of patients with cirrhosis had APRI ≥2 and 41.3% had a FIB-4 ≥2.67 compared to 1.2% and 8.9% in control patients, respectively. In the periods spanning 3-12, 12-21, and 21-30 months prior to cirrhosis diagnosis, APRI was ≥2 in 9.4%, 6.6%, and 6.5% of patients, respectively; FIB-4 was ≥2.67 in 42.1%, 37.1%, and 34.3% of patients, respectively. The sensitivity and specificity of APRI at the time of cirrhosis diagnosis were 9.3% and 98.8%, respectively, while the sensitivity and specificity of FIB-4 were 41.3% and 91.0%, respectively. Lower cut-off values for APRI and FIB-4 showed similar performance.ConclusionsExisting non-invasive fibrosis makers are suboptimal when used for advanced fibrosis identification, missing over half of patients with cirrhosis at the time of and prior to clinical diagnosis.Impact and implicationsCommonly available laboratory-based indices, including APRI and FIB-4, have been proposed to rule in or rule out advanced fibrosis in the general population. In a study of a large privately insured cohort from the US, FIB-4 and APRI were not sufficient for screening for advanced fibrosis at the time of or prior to clinical diagnosis. While performance for screening out advanced fibrosis was better, a significant percentage of patients with cirrhosis have lab indices below threshold values. Future studies to develop laboratory-based algorithms to help stratify liver fibrosis for population-based screening are warranted.
