Association of medical students' reports of interactions with the pharmaceutical and medical device industries and medical school policies and characteristics: a cross-sectional study

Characterizing industry payments to US teaching hospitals and affiliated physicians: a cross-sectional analysis of the Open Payments datasets from 2016 to 2022

Industry payments to US teaching hospitals are common; however, little is known about whether these financial relationships influence affiliated physicians to engage in similar financial relationships with industry. Using national hospital, physician, and industry payment data we investigated trends in industry payments made to US teaching hospitals and affiliated physicians to characterize the magnitude and nature of payments. In addition, we assessed if physicians may be influenced to accept higher value industry payments depending on the value of promotional payments accepted by the teaching hospital they affiliate with. We found that physicians with a US teaching hospital affiliation are associated with accepting higher value industry payments as the total value of industry payments of the teaching hospital increases. Our findings varied by specialty, with surgeons accepting the highest value payments. These results highlight the need for greater public disclosure and awareness of payments to better manage and mitigate industry-biased clinical decision making.

Conflict of Interest Policies at Medical Schools and Teaching Hospitals: A Systematic Review of Cross-sectional Studies

BACKGROUND

This systematic review aims to estimate the proportion of medical schools and teaching hospitals with conflicts of interest (COI) policies for health research and education, to describe the provisions included in the policies and their impact on research outputs and educational quality or content.

METHODS

Experimental and observational studies reporting at least one of the above mentioned aims were included irrespective of language, publication type or geographical setting. MEDLINE, Scopus, Embase and the Cochrane Methodology Register were searched from inception to March 2020. Methodological study quality was assessed using an amended version of the Joanna Briggs Institute's checklist for prevalence studies.

RESULTS

Twenty-two cross-sectional studies were included; all were conducted in high-income countries. Of these, 20 studies estimated the prevalence of COI policies, which ranged from 5% to 100% (median: 85%). Twenty studies assessed the provisions included in COI policies with different assessment methods. Of these, nine analysed the strength of the content of medical schools' COI policies using various assessment tools that looked at a range of policy domains. The mean standardised summary score of policy strength ranged from 2% to 73% (median: 30%), with a low score indicating a weak policy. North American institutions more frequently had COI policies and their content was rated as stronger than policies from European institutions. None of the included studies assessed the impact of COI policies on research outputs or educational quality or content.

CONCLUSION

Prevalence of COI policies at medical schools and teaching hospitals varied greatly in high-income countries. No studies estimated the prevalence of policies in low to middle-income countries. The content of COI policies varied widely and while most European institutions ranked poorly, in North America more medical schools had strong policies. No studies were identified on impact of COI policies on research outputs and educational quality or content.

Industry payments and physicians prescriptions: Effect of a payment restriction policy

The pharmaceutical industry spends billions of dollars every year for marketing its products to US health care providers. This study investigates the association between industry marketing payments and physicians' prescription in New York and Massachusetts, and examines the effect of the Massachusetts payment restriction policy on this association in comparison with the New York State that has no payment restriction policy. Three panel data models (fixed effects regression (FE), first difference regression (FD), and first difference with lagged independent variable (LFD)) were used to establish the association accounting for unobserved confounders and reverse causality. The main indicator is the total amount of industry payments for meals, drug samples, consulting fees, etc. (excluding research funding, and ownership). Dependent variables are a) yearly days' supply of Medicare Part D prescriptions, b) yearly costs of prescribed prescriptions. Secular time trends, as well as differences between the two states were controlled in all models. All three panel models showed significant positive association between industry payments and physician prescriptions. Particularly, these models show that in the base year (2014), a 1% increase in the annual industry payments was associated with (0.01%-0.04%) increase in days' supply of medication, and (0.01%-0.05%) increase in prescription costs for NYS providers. Moreover, FE and FD models show that compared to NYS physicians, the association of industry payments with days' supply and costs of Medicare Part D prescriptions was (0.01%-0.02%) smaller for MA physicians. Because of the smaller sample size and lower power, the LFD model did not detect a significant difference between the NYS and MA providers. The findings of this study provide additional evidence that industry payments are associated with increases in the volume and cost of Medicare prescriptions. Moreover, these findings provide preliminary evidence that payment restriction policies negatively moderate this association, which calls for further research.

Ethics and Industry Interactions: Impact on Specialty Training, Clinical Practice, and Research

Physicians in training and their mentors must be cognizant of ethical concerns related to industry interactions. Mentors perceived to have conflicts of interest or to be engaging in misconduct can unconsciously and profoundly affect the learning and academic environment by implying certain values and expectations. Despite increased awareness of ethical concerns related to industry interactions in clinical practice and research, there remains a need for interventions to prevent ethical transgressions. Ethics education is essential and a move in the right direction, but it alone is likely inadequate in preventing unethical behavior. Education should be supplemented with ethical environments at institutions.

The Association between Industry Payments and Brand-Name Prescriptions in Otolaryngologists

OBJECTIVE

To associate pharmaceutical industry payments to brand-name prescriptions by otolaryngologists.

STUDY DESIGN

Retrospective cross-sectional analysis.

SETTING

Open Payments Database and the Medicare Part D Participant User File 2013-2016.

SUBJECTS AND METHODS

We identified otolaryngologists receiving nonresearch industry payments and prescribing to Medicare Part D recipients. Records were linked by physician name and state. The value of industry payments and the percentage of brand-name drugs prescribed per hospital referral region (HRR) were characterized as medians. Industry payments were correlated to the rate of brand-name prescription by Kendall's τ correlation. This was repeated at the individual physician level and stratified by payment type.

RESULTS

In total, 8167 otolaryngologists received a median of $434 (interquartile range, $138-$1278) in industry compensation over 11 (3-26) payments. Brand-name drugs made up a median of 12.9% (8.6%-18-4%) of each physician's drug claims. The number (τ = 0.05, P < .001) and dollar amount (τ = 0.04, P < .001) of industry payments were correlated with the rate of brand-name drug prescription at the individual physician level. The number of industry payments was also associated with the rate of brand-name prescription by HRR (τ = 0.14, P < .001), but the dollar amount was not. By HRR, food and beverage payments received by physicians were associated with the rate of brand-name drug prescription (τ = 0.04, P < .001), but travel and lodging payments were not.

CONCLUSIONS

Industry financial transactions are associated with brand-name drug prescriptions in otolaryngologists, and these associations are stronger at the regional level than at the individual physician level. These correlations are of modest strength and should be interpreted cautiously by readers.

Antecedents of Symmetry in Physicians’ Prescription Behavior: Evidence from SEM-based Multivariate Approach

The aim of this paper is to examine the direct impact of marketing and medical tools on the symmetry of physicians’ prescription behavior in the context of the Pakistani healthcare sector. This research also investigates the moderating influence of corporate image and customer relationship in an association of marketing & medical tools, and the symmetry of physicians’ prescription behavior. The survey involved a research sample of 740 physicians, comprising 410 general practitioners and 330 specialists. A series of multivariate approaches such as exploratory factor analysis, confirmatory factor analyses, and conditional process analysis are employed. The findings of the study showed that marketing & medical tools have a direct, positive, and significant influence on physicians’ symmetrical prescription behavior. Corporate image and customer relationship have also a significant impact as moderating variables between marketing & medical tools, and the symmetry of prescription behavior of physicians. The outcomes of this research are beneficial to marketers and medical managers in the pharmaceutical industry.

Evaluation of first year student pharmacists' perceptions of the pharmaceutical industry

BACKGROUND AND PURPOSE

There are a limited number of pedagogical studies evaluating student pharmacists' perceptions of the pharmaceutical industry. The objective of this two year prospective study was to evaluate changes in student pharmacists' perceptions of the pharmaceutical industry during the first year of enrollment in the doctor of pharmacy curriculum.

EDUCATIONAL ACTIVITY AND SETTING

An online survey was developed and offered to all first-year student pharmacists during the 2014 and 2015 Fall semesters prior to didactic instruction on the pharmaceutical industry and then again at the end of the respective academic years. Descriptive and inferential statistics were used to analyze the data.

FINDINGS

A majority of students had a positive impression of the pharmaceutical industry in both the fall (75%) and spring semesters (78%). Over the course of the year, significantly greater numbers of student pharmacists reported favorable impressions of the pharmaceutical industry with respect to research innovation, drug safety, and the provision of drug information. On the other hand, findings suggest that many students remain skeptical regarding the benefits of prescription medications relative to cost and there were significant increases in the number of students who perceived pharmaceutical industry-based marketing practices to have a negative impact on patients and society.

DISCUSSION AND SUMMARY

Didactic education may influence student pharmacists' perceptions of the pharmaceutical industry. Further research is warranted to evaluate the role of pharmacy curricula and extra-curricular activities in influencing changes in student pharmacists' perceptions and the potential implications of these changes to pharmacy practice.

Interactions between physicians and the pharmaceutical industry generally and sales representatives specifically and their association with physicians' attitudes and prescribing habits: a systematic review

OBJECTIVES

The objective of this review is to explore interactions between physicians and the pharmaceutical industry including sales representatives and their impact on physicians' attitude and prescribing habits.

DATA SOURCES

PubMed, Embase, Cochrane Library and Google scholar electronic databases were searched from 1992 to August 2016 using free-text words and medical subject headings relevant to the topic.

STUDY SELECTION

Studies included cross-sectional studies, cohort studies, randomised trials and survey designs. Studies with narrative reviews, case reports, opinion polls and letters to the editor were excluded from data synthesis.

DATA EXTRACTION

Two reviewers independently extracted the data. Data on study design, study year, country, participant characteristics, setting and number of participants were collected.

DATA SYNTHESIS

Pharmaceutical industry and pharmaceutical sales representative (PSR) interactions influence physicians' attitudes and their prescribing behaviour and increase the number of formulary addition requests for the company's drug.

CONCLUSION

Physician-pharmaceutical industry and its sales representative's interactions and acceptance of gifts from the company's PSRs have been found to affect physicians' prescribing behaviour and are likely to contribute to irrational prescribing of the company's drug. Therefore, intervention in the form of policy implementation and education about the implications of these interactions is needed.

Conflicts of Interest and Outcomes of Cardiovascular Trials

Conflicts of interests have long been recognized as potential sources of influence in the conduct and reporting of clinical trials. This controversy was again rekindled after the publication of the latest statin guidelines and a series of studies regarding competing interests in leading medical journals. We investigate the association between declared author conflicts and the outcomes of large cardiovascular trials. We searched the Medline (PubMed) database to identify "phase 2" and "phase 3" clinical trials using the search term "cardiovascular" over the past decade using "10 years" as the filter. We perceived the competing interest as present regardless of the nature such as consulting fees, honoraria, travel imbursements, stock holding, and employment. Of the 699 titles retrieved, 114 studies met the inclusion criteria. Nearly 80% of studies had at least a single author with competing interests. The 114 studies had a total of 1,433 investigators, of which 725 had declared conflicts of interests (50.6%). A total of 66 studies (58%) had half or >50 percent of investigators who had some conflicts of interests. Of these studies, 54 studies had favorable outcomes and only 12 had unfavorable outcomes (p <0.001). Among the type of competing interests, consulting or personal fees was the most common present in 58 investigators (51%). This was followed by research grants present in 55 the researchers (48%). Among 25 (22%) studies, at least one investigator reported stakes in the industry, of which only 2 studies had unfavorable outcomes for the intervention being investigated. Just 1 of the 25 clinical trials with a sample size of >1,000 had no investigators with competing interests. In conclusion, authors conflicts are associated with favorable outcomes in cardiovascular outcome trials.

Unhealthy marketing of pharmaceutical products: An international public health concern

I consider the current state of pharmaceutical marketing vis-à-vis ethical and legal standards and advocate measures to improve it. There is abundant evidence of unethical or illicit marketing. It fuels growing concerns about undue corporate influence over pharmaceutical research, education, and consumption. The most extensive evidence of industry transgressions comes from the United States (US), where whistle-blowers are encouraged by financial rewards to help uncover illicit marketing and fraud. Outside the US increasing evidence of transgressions exists. Recently I have observed a range of new measures to align pharmaceutical marketing practices with ethical and legal standards. In the interest of public health, I highlight the need for additional and more profound reforms to ensure that information about medicines supports quality and resource-efficient care.

Medical Schools' Industry Interaction Policies Not Associated With Trainees' Self-Reported Behavior as Residents: Results of a National Survey

BACKGROUND

Medical students attending schools with policies limiting industry/student interactions report fewer relationships with pharmaceutical representatives.

OBJECTIVE

To investigate whether associations between students' medical school policies and their more limited industry interaction behaviors persist into residency.

METHODS

We randomly sampled 1800 third-year residents who graduated from 120 allopathic US-based medical schools, using the American Medical Association Physician Masterfile. We surveyed them in 2011 to determine self-reported behavior and preferences for brand-name prescriptions, and we calculated the strength of their medical schools' industry interaction policies using the 2008 American Medical Student Association and Institute on Medicine as a Profession databases. We used logistic regression to estimate the association between strength of school policies and residents' behaviors with adjustments for class size, postresidency career plan, and concern about medical school debt.

RESULTS

We achieved a 44% survey response rate (n = 739). Residents who graduated from schools with restrictive policies were no more or less likely to accept industry gifts or industry-sponsored meals, speak with marketing representative about drug products, attend industry-sponsored lectures, or prefer brand-name medications than residents who graduated from schools with less restrictive policies. Residents who correctly answered evidence-based prescription questions were about 30% less likely to have attended industry-sponsored lectures (OR = 0.72, 95% CI 0.56-0.98).

CONCLUSIONS

Any effect that medical school industry interaction policies had on insulating students from pharmaceutical marketing did not persist in the behavior of residents in our sample. This suggests that residency training environments are important in influencing behavior.
