Provider-directed marketing may increase prescribing of medications for opioid use disorder

Association Between Open Payments-Reported Industry Transfers of Value and Prostaglandin Analog Prescribing in the US

Importance

Reported transfers of value (TOV) from pharmaceutical companies have been associated with greater use of branded anti-vascular endothelial growth factor agents by ophthalmologists, but payment under the Medicare Part B buy-and-bill model includes a financial incentive to choose costlier agents, potentially confounding analyses of pharmaceutical TOV and prescribing patterns. How these reported TOV are associated with prescribing patterns for prescription eye drops, not subject to the incentives created by Part B payments, should be considered.

Objective

To assess the association between prostaglandin analog (PGA) eye drop prescribing and reported nonresearch TOV by makers of branded PGAs to US vision care professionals.

Design, Setting, and Participants

This retrospective cohort analysis used a 20% nationally representative sample of 2018 Medicare Part D claims and industry TOV reported to the Open Payments program. Optometrists and ophthalmologists who had more than 10 claims for PGA drops in the 20% sample were analyzed. Analysis took place from June 2021 to February 2022.

Main Outcomes and Measures

Multivariable logistic regression assessing the association between membership in strata of reported TOV and branded PGA prescribing rate, controlling for prescriber demographic factors, local area practices, total PGA prescribing volume, and plan formularies involved.

Results

A total of 20 612 ophthalmologists and 5426 optometrists (7449 [29%] female and 18 589 [71%] male) prescribed PGA eye drops. Of these, 9685 (37%) were reported to have received TOV from manufacturers of branded PGAs in 2018, totaling $5 060 346. The median (IQR) reported TOV was $65 ($24-$147). Multivariable logistic regression showed that the predicted probability of primarily prescribing branded PGAs among prescribers who reported receiving no TOV was 12.9% (95% CI, 12.4%-13.4%). This figure increased to 19.6% (95% CI, 18.8%-20.4%) among prescribers receiving TOV, a 50% increase. There was a dose-response association, such that the top 10% of TOV recipients had a 29.2% probability (95% CI, 26.4%-31.9%) of preferential branded use.

Conclusions and Relevance

While the median reported TOV to a PGA prescriber was relatively low in this study, there was a positive association between amount of reported nonresearch TOV received from PGA makers and the frequency of branded PGA use. This shows that small reported TOV were associated with differences in prescribing. High rates of branded PGA prescribing may pose a cost burden to patients that affects adherence. Clinicians and policy makers should be aware of these associations.

Promotional Payments to Medical Oncologists and Urologists and Prescriptions for Abiraterone and Enzalutamide

OBJECTIVE

To understand the influence of drug manufacturers on the prescribing patterns of medical oncologists and urologists, we examined the relationship between promotional payments from the manufacturers of abiraterone and enzalutamide and prescriptions for either drug by medical oncologists and urologists.

METHODS

Promotional payments for abiraterone or enzalutamide made to medical oncologists and urologists between January 2014 and December 2017 reported through the Open Payments Program were categorized as $0, $1$999, and $1000 or more. Prescriptions filled between January 2013 and December 2017 were identified in the Medicare Part D File. Associations between promotional payments and prescribing were assessed using generalized linear models.

RESULTS

From 2013 through 2017, the number of medical oncologists and urologists prescribing abiraterone or enzalutamide increased by 38% - 298%, respectively. The odds of prescribing among medical oncologists receiving $1--$999 and those receiving $1,000 or more were 1.69 (95%CI:1.59--1.79) and 2.61 (95% CI: 2.14--3.18) times that of medical oncologists receiving no payments. Among urologists receiving $1--$999 and those receiving $1,000 or more, the odds of prescribing were 4.04 (95%CI: 3.59--4.54) and 13.57 (95%CI: 9.69--19.0) times that of urologists receiving no payments.

CONCLUSION

Increasing promotional payments were associated with prescribing among medical oncologists and urologists, with a stronger relationship evident for urologists. Prescribing patterns for abiraterone and enzalutamide, particularly among urologists, may be influenced by payments from drug manufacturers.

Strategies to improve implementation of medications for opioid use disorder reported by veterans involved in the legal system: A qualitative study

BACKGROUND

Veterans involved in the legal system have a high risk of overdose mortality but limited utilization of medications for opioid use disorder (MOUD). To increase the use of MOUD in Veterans Health Administration (VHA) facilities and reduce overdose mortality, the VHA should incorporate strategies identified by legal-involved veterans to improve quality of care and ensure that their patients' experiences are integrated into care delivery. This study aims to determine strategies to increase use of MOUD from the perspective of legal-involved veterans with a history of opioid use or opioid use disorder (OUD).

METHODS

Between February 2018 and March 2019, we conducted semistructured interviews with 18 veterans with a history of opioid use or OUD and legal involvement (15 men and 3 women; mean age 41, standard deviation 13, range 28-61). Veterans were from 9 geographically dispersed United States VHA facilities. The study analyzed verbatim transcripts using the framework method. The primary focus was themes that represented legal-involved veteran-identified strategies to improve the use of MOUD.

RESULTS

The 18 veterans interviewed had legal involvement directly related to their opioid use and most (n = 15; 83%) had previously used MOUD. Veteran-identified strategies to improve access to and use of MOUD included: (1) VHA should provide transportation or telehealth services; (2) legal agencies should increase access to MOUD during incarceration; (3) the VHA should reduce physician turnover; (4) the VHA should improve physician education to deliver compassionate, patient-centered treatment; (5) the VHA should improve veteran education about MOUD; and (6) the VHA should provide social support opportunities to veterans.

CONCLUSIONS

Legal-involved veterans provided strategies that can inform and expand MOUD to better meet their needs and the treatment needs of all patients with OUD. The VHA should consider incorporating these strategies into care, and should evaluate their impact on patients' experience, initiation of and retention on medications, and overdose rates.

Are Financial Payments From the Pharmaceutical Industry Associated With Physician Prescribing? : A Systematic Review

BACKGROUND

Financial payments from the drug industry to U.S. physicians are common. Payments may influence physicians' clinical decision making and drug prescribing.

PURPOSE

To evaluate whether receipt of payments from the drug industry is associated with physician prescribing practices.

DATA SOURCES

MEDLINE (Ovid), Embase, the Cochrane Library, Web of Science, and EconLit were searched without language restrictions. The search had no limiting start date and concluded on 16 September 2020.

STUDY SELECTION

Studies that estimated the association between receipt of industry payments (exposure) and prescribing (outcome).

DATA EXTRACTION

Pairs of reviewers extracted the primary analysis or analyses from each study and evaluated risk of bias (ROB).

DATA SYNTHESIS

Thirty-six studies comprising 101 analyses were included. Most studies (n = 30) identified a positive association between payments and prescribing in all analyses; the remainder (n = 6) had a mix of positive and null findings. No study had only null findings. Of 101 individual analyses, 89 identified a positive association. Payments were associated with increased prescribing of the paying company's drug, increased prescribing costs, and increased prescribing of branded drugs. Nine studies assessed and found evidence of a temporal association; 25 assessed and found evidence of a dose-response relationship.

LIMITATION

The design was observational, 21 of 36 studies had serious ROB, and publication bias was possible.

CONCLUSION

The association between industry payments and physician prescribing was consistent across all studies that have evaluated this association. Findings regarding a temporal association and dose-response suggest a causal relationship.

Comparison of Rural vs Urban Direct-to-Physician Commercial Promotion of Medications for Treating Opioid Use Disorder

IMPORTANCE

In the United States, access to medications prescribed for opioid use disorder (OUD) is lower in rural counties than in urban counties. Considering the positive associations between direct-to-physician promotion of opiates and OUD medications and their prescribing rates, a study examining the association between pharmaceutical promotion of these medications and county-level rurality has merit.

OBJECTIVE

To assess whether rural counties received less pharmaceutical promotion of OUD medications compared with urban counties.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional county-level study used all reported direct-to-physician pharmaceutical payments from manufacturers of medications prescribed for OUD from January 1, 2014, through December 31, 2017, as well as demographic and economic data at the county level from 3140 US counties. Logistic regression was used with year and state-level fixed effects to compare rural county and urban county odds of receiving any promotion of OUD medications. A negative binomial model was used with year and state-level fixed effects to compare the mean pharmaceutical payments per physician and per population in rural vs urban counties.

MAIN OUTCOMES AND MEASURES

A binary indicator for whether physicians in a county received any promotion related to OUD medications in a year. The second outcome was the value of promotion (eg, meals), with dollar amount of payments for each county by year. Counties were separated into metropolitan, micropolitan, and rural categories using the National Center for Health Statistics Urban-Rural Classification Scheme.

RESULTS

Of 3140 US counties with 18 318 physicians to whom promotion of OUD medications was directed, 1166 (37.1%) were metropolitan (16 740 physicians [91.4%]), 641 (20.4%) were micropolitan (1049 physicians [5.7%]), and 1333 (42.5%) were rural (529 physicians [2.9%]). Compared with physicians in metropolitan counties, physicians in rural counties had reduced odds of receiving any promotion (adjusted odds ratio, 0.57; 95% CI, 0.44-0.74) and received lower payments (adjusted incidence rate ratio, 0.24; 95% CI, 0.17-0.34).

CONCLUSIONS AND RELEVANCE

The study findings suggest that promotion for OUD medications is less likely to occur in rural counties and that this difference in promotion of OUD medications may be associated with differential commercial costs and benefits of promotion in rural settings.
