Decline in opioid prescribing after federal rescheduling of hydrocodone products.

ABSTRACT: PURPOSE:To examine differences in opioid prescribing by patient characteristics and variation in hydrocodone combination product (HCP) prescribing attributed to states, before and after the 2014 Drug Enforcement Administration's reclassification of HCP from schedule III to the more restrictive schedule II. METHODS:We used 2013 to 2015 data for 9 202 958 patients aged 18 to 64 from a large nationally representative commercial health insurance program to assess the temporal trends in the monthly rate of opioid prescribing. RESULTS:HCP prescribing decreased by 26% from June 2013 to June 2015; the rate of prescriptions for any opioid decreased by 11%. Prescribing of non-hydrocodone schedule III opioids increased slightly while prescribing of non-hydrocodone schedule II opioids and tramadol was stable. Absolute decreases in HCP prescribing rates were larger in patients being treated for cancer (-2.26% vs -0.7% for non-cancer patients, P < 0.0001) and in those with high comorbidities (-2.13% vs -0.55% for those with no comorbidity, P < 0.0001). Differences in the absolute and relative changes in HCP prescribing rates among states were large; for example, a relative decrease of 46.7% in Texas and a 12.7% increase in South Dakota. The variation in HCP prescribing attributable to the state of residence increased from 6.6% in 2013 to 8.7% in 2015. CONCLUSIONS:The 2014 federal policy was associated with a decrease in rates of HCP and total opioid prescribing. The large decrease in the rates of HCP prescribing for patients with actively treated cancer may represent an unintended consequence.

Project description:BackgroundIn 2014, the U.S. Drug Enforcement Agency reclassified hydrocodone from Schedule III to Schedule II of the Controlled Substances Act, resulting in new restrictions on refills. The authors hypothesized that hydrocodone rescheduling led to decreases in total opioid dispensing within 30 days of surgery and reduced new long-term opioid dispensing among surgical patients.MethodsThe authors studied privately insured, opioid-naïve adults undergoing 10 general or orthopedic surgeries between 2011 and 2015. The authors conducted a differences-in-differences analysis that compared overall opioid dispensing before versus after the rescheduling rule for patients treated by surgeons who frequently prescribed hydrocodone before rescheduling (i.e., patients who were functionally exposed to rescheduling's impact) while adjusting for secular trends via a comparison group of patients treated by surgeons who rarely prescribed hydrocodone (i.e., unexposed patients). The primary outcome was any filled opioid prescription between 90 and 180 days after surgery; secondary outcomes included the 30-day refill rate and the amount of opioids dispensed initially and at 30 days postoperatively.ResultsThe sample included 65,136 patients. The percentage of patients filling a prescription beyond 90 days was similar after versus before rescheduling (absolute risk difference, -1.1%; 95% CI, -2.3% to 0.1%; P = 0.084). The authors estimated the rescheduling rule to be associated with a 45.4-mg oral morphine equivalent increase (difference-in-differences estimate; 95% CI, 34.2-56.7 mg; P < 0.001) in initial opioid dispensing, a 4.1% absolute decrease (95% CI, -5.5% to -2.7%; P < 0.001) in refills within 30 days, and a 37.7-mg oral morphine equivalent increase (95% CI, 20.6-54.8 mg; P = 0.008) in opioids dispensed within 30 days.ConclusionsAmong patients treated by surgeons who frequently prescribed hydrocodone before the Drug Enforcement Agency 2014 hydrocodone rescheduling rule, rescheduling did not impact long-term opioid receipt, although it was associated with an increase in opioid dispensing within 30 days of surgery.

Project description:BackgroundGiven concerns about suboptimal pain management for actively treated cancer patients following the 2014 federal reclassification of hydrocodone, we examined changes in patterns of opioid prescribing among surgical breast cancer patients.Materials and methodsData from a large nationally representative commercial health insurance program from 2009 to 2017 were used to identify women aged 18 years and older who were diagnosed with carcinoma in-situ or malignant breast cancer and received breast-conserving surgery or mastectomy from 2010 to 2016. Generalized linear mixed models were used to estimate the adjusted odds ratio (aOR) for receipt of ≥1-day, >30-day, or ≥ 90-day supply of opioids in the 12 months following surgery adjusting for demographics, cancer treatment-related characteristics, and preoperative opioid use.ResultsA total of 60,080 patients were included in the study. Surgically treated breast cancer patients in 2015 (aOR = 0.90, 0.84-0.97) and 2016 (aOR = 0.80, 0.74-0.86) were less likely to receive ≥1-day supply of opioid prescriptions when compared with patients in 2013. Patients who had surgery in 2015 (aOR = 0.89, 0.81-0.98) and 2016 (aOR = 0.80, 0.73-0.87) were also less likely to receive >30-day supply of prescription opioids in the 12 months following surgery. However, only surgical breast cancer patients in 2016 were less likely to receive ≥90-day supply (aOR = 0.86, 0.76-0.98).ConclusionSurgically treated breast cancer patients are less likely to receive short- and long-term opioid prescriptions following the implementation of hydrocodone rescheduling. Further studies on the potential impact of federal policy on cancer patient pain management are needed.Implications for practiceClinicians and researchers with diverse perspectives should be included as stakeholders during policy development for restricting opioid prescriptions. Stakeholders can identify potential unintended consequences early and help identify methods to mitigate concerns, specifically as it relates to policy that influences how providers manage pain for actively treated cancer patients. This work shows how federal policy may have led to declines in opioid prescribing for breast cancer patients who underwent mastectomy or breast-conserving surgery.

Project description:Importance:In 2014, the US Drug Enforcement Administration moved hydrocodone-containing analgesics from schedule III to the more restrictive schedule II to limit prescribing and decrease nonmedical opioid use. The association of this policy change with postoperative prescribing is not well understood. Objective:To examine the hypothesis that the amount of opioids prescribed following surgery is associated with the rescheduling of hydrocodone. Design, Setting, and Participants:An interrupted time series analysis of outpatient opioid prescriptions was conducted to examine the trends in the amount of postoperative opioids filled before and after the schedule change. Opioid prescriptions filled between January 2012 and October 2015 were analyzed using insurance claims data from the Michigan Value Collaborative, which includes data from 75 hospitals across Michigan. A total of 21 955 adult inpatients 18 to 64 years of age who underwent 1 of 19 common elective surgical procedures and filled an opioid prescription within 14 days of discharge to home were eligible for inclusion. Main Outcomes and Measures:The primary outcome was the trends in the mean amount of opioids filled in oral morphine equivalents (OMEs) for the initial postoperative prescriptions before and after the schedule change date of October 6, 2014, compared using interrupted time series and multivariable regression analyses. Secondary outcomes included the total amount of opioids filled and the refill rate for the 30-day postoperative period. Subgroup analyses were performed by hydrocodone prescriptions, nonhydrocodone prescriptions, surgical procedure, and prior opioid use. Results:Data from 21 955 patients undergoing surgical procedures across 75 hospitals and 5120 prescribers were analyzed. Cohorts before and after the schedule change were equivalent with respect to sex (10 197 of 15 791 [64.6%] vs 3966 of 6169 [64.3%] female; P = .69) and mean (SE) age (47.9 [11.2] vs 47.7 [11.3] years; P = .19). After the schedule change, the mean OMEs filled in the initial opioid prescription increased by approximately 35 OMEs (β = 35.1 [13.2]; P < .01), equivalent to 7 tablets of hydrocodone (5 mg). There were no significant differences in the total OMEs filled during the 30-day postoperative period before and after the schedule change (β = 18.3 [30.5]; P = .55), but there was a significant decrease in the refill rate (β = -5.2% [1.3%]; P < .001). Conclusions and Relevance:Changing hydrocodone from schedule III to schedule II was associated with an increase in the amount of opioids filled in the initial prescription following surgery. Opioid-related policies require close follow-up to identify and address early unintended effects given the multitude of competing factors that influence health care professional prescribing behaviors.

Project description:Importance:Since the Centers for Disease Control and Prevention published opioid prescribing guidelines in March 2016, 31 states have implemented legislation to restrict the duration of opioid prescriptions for acute pain. However, the association of these policies with the amount of opioid prescribed following surgery remains unknown. Objective:To examine the association of opioid prescribing duration limits with postoperative opioid prescribing in Massachusetts and Connecticut, the first 2 states to implement limits after March 2016. Design, Setting, and Participants:This interrupted time series analysis and cross-sectional study examined immediate level and slope changes in monthly outcomes after prescribing limit implementation in Massachusetts and Connecticut. These states implemented 7-day limits on initial opioid prescriptions on March 14, 2016, and July 1, 2016, respectively. Using the 2014 to 2017 IBM MarketScan Research Database, 16?281 opioid-naive adults in these states who filled a prescription within 3 days of surgery between July 1, 2014, and November 30, 2017, were identified. Data were analyzed from December 2018 to June 2019. Main Outcomes and Measures:The primary outcome was the prescription size in oral morphine equivalents (OMEs) for the initial postoperative opioid prescription (one 5/325 mg hydrocodone-acetaminophen pill?=?5 OMEs). Secondary outcomes included days supplied in the initial prescription and the proportion of initial prescriptions exceeding a 7-day supply. Results:In total, 16?281 opioid-naive patients (9708 [59.6%] female; median [interquartile range] age range, 45-54 [35-44 to 55-64] years) undergoing surgical procedures were included. In Massachusetts, there were 5340 and 5435 patients in the preimplementation and postimplementation periods, respectively. In Connecticut, there were 2869 and 2637 patients in the preimplementation and postimplementation periods, respectively. Limit implementation in Massachusetts was associated with an immediate mean level decrease in prescription size (-38 OMEs [95% CI, -44 to -32 OMEs]) and with a mean decrease in slope (-1.5 OMEs/mo [95% CI, -2.1 to -0.9 OMEs/mo]). Implementation was also associated with an immediate mean level decrease in days supplied (-0.4 days [95% CI, -0.6 to -0.2 days]) and the proportion of prescriptions exceeding a 7-day supply (-5.9 percentage points [95% CI, -7.9 to -3.9 percentage points]). In contrast, limit implementation in Connecticut was not associated with level or slope changes in any outcome. Conclusions and Relevance:Opioid prescribing duration limits had a variable association with postoperative opioid prescribing in Massachusetts and Connecticut. The mean opioid prescription size filled, days supplied, and prescribing exceeding a 7-day supply decreased after limit implementation in Massachusetts only. Given the potential differences in policy dissemination and uptake, efforts to reduce opioid prescribing should also include surgeon education and evidence-based prescribing recommendations.

Project description:BackgroundChronic opioid therapy for chronic pain treatment has increased. Hospital physicians, including hospitalists and medical/surgical resident physicians, care for many hospitalized patients, yet little is known about opioid prescribing at hospital discharge and future chronic opioid use.ObjectiveWe aimed to characterize opioid prescribing at hospital discharge among 'opioid naïve' patients. Opioid naïve patients had not filled an opioid prescription at an affiliated pharmacy 1 year preceding their hospital discharge. We also set out to quantify the risk of chronic opioid use and opioid refills 1 year post discharge among opioid naïve patients with and without opioid receipt at discharge.DesignThis was a retrospective cohort study.ParticipantsFrom 1 January 2011 to 31 December 2011, 6,689 opioid naïve patients were discharged from a safety-net hospital.Main measureChronic opioid use 1 year post discharge.Key resultsTwenty-five percent of opioid naïve patients (n?=?1,688) had opioid receipt within 72 hours of discharge. Patients with opioid receipt were more likely to have diagnoses including neoplasm (6.3% versus 3.5%, p?<?0.001), acute pain (2.7% versus 1.0 %, p?<?0.001), chronic pain at admission (12.1% versus 3.3%, p?<?0.001) or surgery during their hospitalization (65.1% versus 18.4%, p?<?0.001) compared to patients without opioid receipt. Patients with opioid receipt were less likely to have alcohol use disorders (15.7% versus 20.7%, p?<?0.001) and mental health disorders (23.9% versus 31.4%, p?<?0.001) compared to patients without opioid receipt. Chronic opioid use 1 year post discharge was more common among patients with opioid receipt (4.1% versus 1.3%, p?<?0.0001) compared to patients without opioid receipt. Opioid receipt was associated with increased odds of chronic opioid use (AOR?=?4.90, 95% CI 3.22-7.45) and greater subsequent opioid refills (AOR?=?2.67, 95% CI 2.29-3.13) 1 year post discharge compared to no opioid receipt.ConclusionOpioid receipt at hospital discharge among opioid naïve patients increased future chronic opioid use. Physicians should inform patients of this risk prior to prescribing opioids at discharge.
