Opioid Prescribing Trends in Women Following Mastectomy or Breast-Conserving Surgery Before and After the 2014 Federal Reclassification of Hydrocodone.

ABSTRACT: BACKGROUND:Given 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 METHODS:Data 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. RESULTS:A 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). CONCLUSION:Surgically 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 PRACTICE:Clinicians 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: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:Introduction: The early randomized controlled trials revealed no differences in survival between breast-conserving surgery (BCS) and mastectomy. However, breast cancer treatment has undergone changes, and the results of recent population-based registry studies suggest superior long-term survival after BCS. To explore the current evidence, a systematic review and meta-ana lysis of population-based observational studies from 2010 and onward was conducted. Methods: A literature search was conducted in the PubMed, Embase, and Cochrane databases to identify relevant literature. Keywords included “mastectomy,” “breast conserving surgery,” and “survival.” The identified studies were narratively reviewed and effect sizes (hazard ratios [HRs]) for overall (OS) and breast cancer-specific survival (BCSS) were combined with random-effects models. Results: A total of 30 reports were included in the review, and results from 25 studies were included in the meta-analyses. Compared with mastectomy, BCS was associated with better OS (HR = 1.34 [1.20–1.51]; N = 1,311,600) and BCSS (HR = 1.38 [1.29–1.47]; N = 494,267). Selected subgroups of patients, based on lymph node status, age (<50 years/≥50 years), and radiation therapy after mastectomy (±), all showed better overall survival after BCS. The number (range 4–12) and type of prognostic variables adjusted for in the survival analyses of the studies did not statistically significantly moderate the differences in survival between BCS and mastectomy. Conclusions: The combined findings from large population-based studies indicate that BCS is associated with survival benefit compared with mastectomy, suggesting that BCS be the recommended treatment of early breast cancer (T1-2N0-1M0) if a radical lumpectomy can be performed. Mini-Abstract: A systematic review and meta-analysis of population-based observational studies comparing the survival after breast-conserving surgery and mastectomy in patients with breast cancer. The review comprises 30 papers from 2010 to 2021. More than 1.3 million patients are included in the meta-analyses.

Project description:ImportancePrevious research has shown an immediate reduction in new opioid users and use after implementation of the opioid supply restriction laws. Assessment of the association between opioid restrictions and alternative treatment options, such as nonsteroidal anti-inflammatory drugs (NSAIDs), is needed to evaluate potential unintended consequences for patients requiring analgesia.ObjectiveTo evaluate the association between an opioid restriction law in Florida and use of prescription NSAIDs.Design, setting, and participantsThis quality improvement study used interrupted time series analyses accounting for autocorrelation to estimate immediate and trend changes in the prescribing and use of prescription NSAIDs in Florida before and after implementation of a state law limiting opioid prescriptions to a 3-day supply. Participants were enrollees in a single private health plan of a large university and health system employer in Florida from January 2015 to June 2019.ExposuresPrescriptions for NSAIDs, ascertained from pharmacy claims data.Main outcomes and measuresThe following outcomes were calculated monthly per 1000 plan enrollees: (1) number of NSAID users; (2) mean days' supply of NSAIDs per prescription; and (3) mean number of NSAID prescriptions. Individuals were classified as NSAID users if they had at least 1 NSAID prescription in a given month. Analysis was stratified by route of NSAID administration (oral or nonoral).ResultsAmong 46 783 NSAID users with 79 089 NSAID prescriptions during the study period, the median age was 47 years (interquartile range, 35-57 years). After implementation of the opioid restriction law, the number of NSAID users immediately increased, but the difference was not significant (change, 0.82 per 1000 patients; 95% CI, -0.67 to 2.30 per 1000 patients). No significant change in the days' supply of oral NSAID users occurred (change, 0.21 days per prescription; 95% CI, -1.66 to 2.08 days per prescription). Before implementation of the law, there was a nonsignificant decreasing trend in NSAID prescriptions (rate of change, -0.03 per month per 1000 enrollees; 95% CI, -0.13 to 0.07 per month per 1000 enrollees; after implementation, there was a nonsignificant increase in the number of oral and nonoral NSAID prescriptions (change, 1.49 per 1000 enrollees; 95% CI, -3.38 to 6.37 per 1000 enrollees).Conclusions and relevanceIn this quality improvement study, prescribing and use of prescription NSAIDs did not increase after implementation of a law restricting opioid analgesic prescriptions in Florida. These findings suggest possible greater use of over-the-counter NSAIDs after implementation of the law, but further research is needed to evaluate changes in the use of nonopioid analgesics and alternative pain therapies.

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.
