Opioid and non-opioid analgesic regimens after fracture and risk of serious opioid-related events.

ABSTRACT:

Background

Non-opioid analgesics are prescribed in combination with opioids among patients with long bone fracture to reduce opioid prescribing needs, yet evidence is limited on whether they reduce the risk of serious opioid-related events (SOREs). We compared the risk of SOREs among hospitalized patients with long bone fracture discharged with filled opioid prescriptions, with and without non-opioid analgesics.

Design

We identified a retrospective cohort of analgesic-naïve adult patients with a long bone fracture hospitalization using the Merative MarketScan Commercial Database (2013-2020). The exposure was opioid and non-opioid analgesic (gabapentinoids, muscle relaxants, non-steroidal anti-inflammatory drugs, acetaminophen) prescriptions filled in the 3 days before through 42 days after discharge. The outcome was the development of new persistent opioid use or opioid use disorder during follow-up (day 43 through day 408 after discharge). We used Cox proportional hazards regression with inverse probability of treatment weighting with overlap trimming to compare outcomes among those that filled an opioid and a non-opioid analgesic to those that filled only an opioid analgesic. In secondary analyses, we used separate models to compare those that filled a prescription for each specific non-opioid analgesic type with opioids to those that filled only opioids.

Results

Of 29 489 patients, most filled an opioid prescription alone (58.4%) or an opioid and non-opioid (22.0%). In the weighted proportional hazards regression model accounting for relevant covariates and total MME, filling both a non-opioid analgesic and an opioid analgesic was associated with 1.63 times increased risk of SOREs compared with filling an opioid analgesic only (95% CI 1.41 to 1.89). Filling a gabapentin prescription in combination with an opioid was associated with an increased risk of SOREs compared with those that filled an opioid only (adjusted HR: 1.84 (95% CI1.48 to 2.27)).

Conclusions

Filling a non-opioid analgesic in combination with an opioid was associated with an increased risk of SOREs after long bone fracture.

Project description:ImportanceOpioid analgesics may be associated with increased risk of falls, particularly among older adults.ObjectiveTo quantify the age-related risk of serious fall events among adults prescribed opioids by opioid exposure, time from initiation, and daily dose.Design, setting, and participantsThis population-based cohort study conducted in New South Wales, Australia, used data linking national pharmaceutical claims to national and state datasets, including information on sociodemographic characteristics, clinical characteristics, medicines use, health services utilization, and mortality (POPPY II study). It included adults (18 years or older) who initiated prescription opioid treatment, which was defined as no prior dispensing during the preceding 365 days, between January 1, 2005, and December 31, 2018. Data were analyzed from February to June 2023.ExposureTime-dependent periods of opioid exposure were evaluated from dispensing records.Main outcome and measuresSerious fall events identified from emergency department, hospitalization, and mortality records. Negative binomial models were used to assess associations between time-dependent opioid exposure (overall, by time from initiation, and by dose), age, and risk of fall events. Models were adjusted for known fall risk factors, including other fall risk-increasing drugs, frailty risk, and prior serious fall events.ResultsThe cohort comprised 3 212 369 individuals who initiated prescription opioid treatment (1 702 332 women [53%]; median [IQR] age at initiation, 49 [32-65] years). Overall, 506 573 serious fall events were identified, including 5210 fatal falls. During exposure to opioids, the risk of serious fall events was elevated among all age groups; compared with the group aged 18 to 44 years, this risk was highest among those 85 years or older (adjusted incident rate ratio, 6.35; 95% CI, 6.20-6.51). Across all age groups, the first 28 days following opioid initiation was a time of increased serious fall risk; this risk increased with age. Among individuals aged 18 to 84 years, associations were identified between higher daily opioid doses and serious fall events.Conclusions and relevanceThe results of this cohort study suggest that prescription opioids were associated with increased risk of serious fall events among adults of all ages, with individuals 85 years or older at greatest risk. These risks should be considered when prescribing opioids, particularly for individuals with preexisting risk factors or when opioids are prescribed at higher doses. Targeted falls prevention efforts may be most effective within the first month following opioid initiation.

Project description:BackgroundOpioid analgesics are commonly prescribed to women after cesarean delivery. There is a growing effort to prescribe opioids judiciously; however, the risk of serious opioid-related events associated with specific prescribing patterns after cesarean delivery remains unclear.ObjectiveWe examined the association between the dosage of the first opioid prescription filled after cesarean delivery and the risk of serious opioid-related events.Study designWe identified opioid-naïve women with a cesarean delivery enrolled in Tennessee Medicaid (2007-2014). Pharmacy prescription fill data characterized opioids filled within 5 days after delivery. Patients were followed up from day 5 after delivery to the earliest of the following: serious opioid-related event (persistent opioid use, evidence of opioid use disorder [diagnosis or methadone or buprenorphine fill], overdose, or opioid-related death), non-opioid-related death, enrollment loss, or 365th day. We estimated the adjusted hazard ratios and 95% confidence intervals for the serious opioid-related event outcomes based on the dosage (morphine milligram equivalents) of the first filled opioid prescription, adjusting for baseline sociodemographic characteristics, delivery complications, multiple deliveries, comorbidities, and medication use. Secondary analyses examined the role of commonly prescribed opioid strengths and quantities.ResultsThe overall incidence rate of serious opioid-related events among women after cesarean delivery was 3.0 per 100 person-years. Compared with women who did not fill an opioid prescription, the rate of serious opioid-related events was higher among women who filled an opioid prescription, although only significantly higher among women who filled a total dosage of ≥100 morphine milligram equivalents (97.1% of opioid prescriptions). In the secondary analyses, women with a low prescribed daily opioid dosage and women with a low prescribed number of oxycodone (5 mg) tablets (<10 tablets) were not at increased risk of serious opioid-related events compared with women who did not fill an opioid prescription.ConclusionOpioid-naïve women who filled a postpartum opioid prescription at commonly prescribed doses after cesarean delivery had an increased risk of serious opioid-related events compared to women who did not fill a postpartum opioid prescription. Low opioid doses were not associated with a significant increase in the risk of serious opioid-related events.
