Implementation of an Opioid Guideline Impacts on Opioid Prescriptions, Adverse Outcomes, and an Association with a State Opioid-Related Fatalities

Evidence-based clinical practice guideline for the pharmacologic management of acute dental pain in adolescents, adults, and older adults: A report from the American Dental Association Science and Research Institute, the University of Pittsburgh, and the University of Pennsylvania

BACKGROUND

A panel convened by the American Dental Association Science and Research Institute, the University of Pittsburgh, and the University of Pennsylvania conducted systematic reviews and meta-analyses and formulated evidence-based recommendations for the pharmacologic management of acute dental pain after simple and surgical tooth extraction(s) and for the temporary management (ie, definitive dental treatment not immediately available) of toothache associated with pulp and periapical diseases in adolescents, adults, and older adults.

TYPES OF STUDIES REVIEWED

The panel conducted 4 systematic reviews to determine the effect of opioid and nonopioid analgesics, local anesthetics, corticosteroids, and topical anesthetics on acute dental pain. The panel used the Grading of Recommendations, Assessment, Development and Evaluation approach to assess the certainty of the evidence and the Grading of Recommendations, Assessment, Development and Evaluation Evidence-to-Decision Framework to formulate recommendations.

RESULTS

The panel formulated recommendations and good practice statements using the best available evidence. There is a beneficial net balance favoring the use of nonopioid medications compared with opioid medications. In particular, nonsteroidal anti-inflammatory drugs alone or in combination with acetaminophen likely provide superior pain relief with a more favorable safety profile than opioids.

CONCLUSIONS AND PRACTICAL IMPLICATIONS

Nonopioid medications are first-line therapy for managing acute dental pain after tooth extraction(s) and the temporary management of toothache. The use of opioids should be reserved for clinical situations when the first-line therapy is insufficient to reduce pain or there is contraindication of nonsteroidal anti-inflammatory drugs. Clinicians should avoid the routine use of just-in-case prescribing of opioids and should exert extreme caution when prescribing opioids to adolescents and young adults.

Opioid Legislation Decreases Opioid Prescribing in Total Knee Arthroplasty

The purpose of this study was to evaluate the impact of opioid-limiting legislation on perioperative opioid prescriptions in total knee arthroplasty. The hypothesis was that opioid legislation has reduced opioid prescription filling above levels anticipated by national trends. This study retrospectively evaluated opioid prescription filling for all patients undergoing total knee arthroplasty in a commercially available insurance database between 2010 and 2018 (n=1,068,764). Initial discharge and 90-day cumulative oxycodone 5-mg equivalents filled were tabulated. Opioid prescription filling was evaluated over time and between states with and without opioid-limiting legislation using analysis of variance and multivariable linear and logistic regression. States with and without opioid legislation had significant reductions in initial and cumulative opioid prescription filling volume (all P<.001). However, the magnitude of this reduction was larger in states with opioid legislation. Legislation targeting duration and volume had the largest impact on initial post-act opioid prescription filling volume compared with states without legislation in an estimated "pre-act" time frame. Legislation targeting duration and volume and no specific target had the largest impact on cumulative post-act opioid prescription filling volume. States without legislation still had large, significant reductions in filling volume, but the magnitude was not as great as in states with opioid legislation. States with and without opioid legislation had significant decreases in initial and cumulative opioid prescription filling volume. However, the magnitude of reduction was larger in states that enacted legislation. Younger age, pre-operative opioid use, and higher comorbidity burden were associated with greater opioid use postoperatively. [Orthopedics. 202x;4x(x):xx-xx.].

Impact evaluation of a brief online training module on physician use of the Maryland, USA, Prescription Drug Monitoring Program

Background

Prescription Drug Monitoring Programs (PDMPs) are electronic databases that track controlled substance prescriptions in a state. They are underused tools in preventing opioid abuse. Most PDMP education research measures changes in knowledge or confidence rather than behavior.

Objective

To evaluate the impact of online case-based training on healthcare provider use of the Maryland (USA) PDMP.

Methods

We used e-mail distribution lists to recruit providers to complete a brief educational module. Using a pre-training and post-training survey in the module, we measured self-reported PDMP use patterns and perceived PDMP value in specific clinical situations and compared pre- and post-training responses. Within the module, we presented three fictional pain cases and asked participants how they would manage each, both before, and then after presenting prescription drug history simulating a PDMP report. We measured changes in the fictional case treatment plans before and after seeing prescription history. Finally, we measured and compared how often each participant accessed the Maryland PDMP database before and after completing the educational module. We used multivariate logistic regression to measure the effect of the intervention on actual PDMP use frequency.

Results

One hundred and fifty participants enrolled and completed the training module, and we successfully retrieved real-world PDMP use data of 137 of them. Participants’ decisions to prescribe opioids changed significantly after reviewing PDMP data in each of the fictional cases provided in the module. In the months following the training, the rate of PDMP use increased by a median of four use-cases per month among providers in practice for less than 20 years (p = 0.039) and two use-cases per month among infrequent opioid prescribers (p = 0.014).

Conclusion

A brief online case-based educational intervention was associated with a significant increase in the rate of PDMP use among infrequent opioid prescribers and those in practice less than 20 years.

Incidence of Workers' Compensation Claims in Opioid-Using Truck Drivers

OBJECTIVE

This study examines the relationship between opioid use prevalence and subsequent filing of workers' compensation claims.

METHODS

A retrospective cohort study design was utilized to examine data from drivers' initial commercial driver medical exam, employment data, and workers' compensation claims data.

RESULTS

Data from 57,733 over 7 years were analyzed. Drivers who reported opioid use at their initial medical exam visit filed subsequent workers' compensation claims 1.81 times sooner (P = 0.0001; 95% CI 1.34, 2.44) than drivers who did not report opioid use at their CDME when controlling for age, gender, BMI, and diastolic blood pressure.

CONCLUSIONS

These findings provide information that may aid in improving regulations to control for incidents, training programs to inform professional drivers of factors that increase accident risk and educating prescribers about increased risks of injury among opioid-using drivers.

Determining the influence of the Workers Compensation Board of Manitoba's opioid policy on prescription opioid use amongst WCB recipients

BACKGROUND

Opioid medications are commonly used by Workers Compensation Board (WCB) claimants following workplace injuries. The purpose of this study is to describe the impact of an opioid management policy on opioid prescriptions amongst a WCB-covered population compared to changes in the use of these medications in the general population of a Canadian province.

METHODS

We linked WCB claims data from 2006 to 2016 (13,155 claims, 11,905 individuals) to Manitoba provincial health records and compared opioid use amongst this group to 478,606 individuals aged 18-65. Linear regression was performed to examine the change over time in number of individuals being prescribed opioids for various durations and dosages of 50 or more, and 120 or more morphine equivalents (ME)/day for both the WCB and Manitoba population.

RESULTS

WCB claimants totaled 2.5% of Manitoba residents aged 18-65 who were prescribed opioids for non-cancer pain. After the introduction of the opioid use policy for the WCB population in November 2011, the number of people prescribed opioids declined 49.4% in the WCB group, while increasing 10.8% in the province as a whole. The number of individuals using 50 ME/day or more declined 43.1% in the WCB group and increased 5.8% in the province.

CONCLUSIONS

Opioid management programs organized by a compensation board can lead to a substantial reduction in the prescription of opioid medications to a WCB client population, including individuals who were prescribed higher doses of these medications when compared with general trends in the community.

Evaluation of opioid prescription patterns among patients undergoing thyroid surgery

BACKGROUND

There is variability in opioid prescription patterns among surgeons performing thyroidectomy. Thus, the aim of this study is to evaluate opioid prescription rates and opioid use among hemithyroidectomy (HT) and total thyroidectomy (TT) patients.

DESIGN/METHOD

An electronic postoperative survey was distributed to assess opiate use among patients undergoing HT/TT. Groups were compared using t-tests, chi-square tests, and analysis of variance.

RESULTS

A total of 142 opiate naïve patients were included, of which 75 (52.8%) underwent HT and 67 (47.1%) underwent TT. The mean number of tablets prescribed was 21.3 (HT = 22.1, TT = 20.4; P = 0.3), with a mean of 14.1 tablets unused after surgery (HT = 13.2 tablets, TT = 15.0 tablets; P = 0.44). The mean morphine milligram equivalent (MME) prescribed was 150.1 mg (HT = 159.0 mg, TT = 140.2 mg; P = 0.3), with a mean of 98.2 MME unused after surgery (HT = 93.7 mg, TT = 103.2 mg; P = 0.6).

CONCLUSIONS

Opioids are overprescribed after thyroid surgery. Avoidance of overprescribing is vital in mitigating the current opioid crisis.

A Rapid Review of the Impact of Systems-Level Policies and Interventions on Population-Level Outcomes Related to the Opioid Epidemic, United States and Canada, 2014-2018

OBJECTIVES

In the United States, rising rates of overdose deaths and recent outbreaks of hepatitis C virus and HIV infection are associated with injection drug use. We updated a 2014 review of systems-level opioid policy interventions by focusing on evidence published during 2014-2018 and new and expanded opioid policies.

METHODS

We searched the MEDLINE database, consistent with the 2014 review. We included articles that provided original empirical evidence on the effects of systems-level interventions on opioid use, overdose, or death; were from the United States or Canada; had a clear comparison group; and were published from January 1, 2014, through July 19, 2018. Two raters screened articles and extracted full-text data for qualitative synthesis of consistent or contradictory findings across studies. Given the rapidly evolving field, the review was supplemented with a search of additional articles through November 17, 2019, to assess consistency of more recent findings.

RESULTS

The keyword search yielded 535 studies, 66 of which met inclusion criteria. The most studied interventions were prescription drug monitoring programs (PDMPs) (59.1%), and the least studied interventions were clinical guideline changes (7.6%). The most common outcome was opioid use (77.3%). Few articles evaluated combination interventions (18.2%). Study findings included the following: PDMP effectiveness depends on policy design, with robust PDMPs needed for impact; health insurer and pharmacy benefit management strategies, pill-mill laws, pain clinic regulations, and patient/health care provider educational interventions reduced inappropriate prescribing; and marijuana laws led to a decrease in adverse opioid-related outcomes. Naloxone distribution programs were understudied, and evidence of their effectiveness was mixed. In the evidence published after our search's 4-year window, findings on opioid guidelines and education were consistent and findings for other policies differed.

CONCLUSIONS

Although robust PDMPs and marijuana laws are promising, they do not target all outcomes, and multipronged interventions are needed. Future research should address marijuana laws, harm-reduction interventions, health insurer policies, patient/health care provider education, and the effects of simultaneous interventions on opioid-related outcomes.

Morphine Equivalent Dose-Days (MED-D): Predicting the Impact of Opioid Prescription on Total Workers' Compensation Claim Costs for Acute Low Back Pain

OBJECTIVE

To assess the effect of morphine equivalent dose-days (MED-D) on the total cost for acute low back pain (LBP) workers' compensation claims.

METHODS

Simple random samples of 123 opioid and 141 nonopioid acute LBP claims were obtained. Opioid claims were divided into low, medium, and high subgroups for MED-D, MED, and prescription duration. Subgroup mean total costs were compared to the nonopioid group using multivariate regression analyses.

RESULTS

MED-D and prescription duration were each, respectively, associated with significantly increased total costs at both medium and high levels. Increasing MED had a negative association with total cost, though stratification by duration abrogated this perceived trend. Interaction testing indicated MED and duration together better explained cost than MED alone.

CONCLUSION

MED-D is a better predictor of total cost in acute LBP claims than MED alone.
