Industry Funding Is Correlated With Publication Productivity of US Academic Radiation Oncologists.

ABSTRACT:

Purpose

Industry payments to physicians are financial conflicts of interest and may influence research findings and medical decisions. We aim to (1) characterize industry payments within radiation oncology; and (2) explore the potential correlation between receiving disclosed industry payments and academic productivity.

Materials/methods

CMS database was used to extract 2015 industry payments. For academic radiation oncologists, research productivity was characterized by h- and m-indices, as well as receipt of National Institutes of Health (NIH) funding, which is not an industry payment. Logistic regression models were used to determine whether publication metrics (m-index, h-index) and other study characteristics such as gender, PhD status, NIH institution funding status, were associated with the endpoints, research and general payments. Associations between the amount of payments (if any) and publication metrics were further studied using linear regression models.

Results

A total of 22,543 individual payments totaling $25,532,482 to 2,995 radiation oncologists were included. Among the 1,189 academic radiation oncologists, 75% received less than $167; on the other hand, 10 (<1%) individuals received $6,425,728 (51%) of payments. On multiple logistic regression, research payments were significantly associated with the m-index, odds ratio 2.86 (95% confidence interval, 1.84-4.45, p-value <0.0001); as well as with the h-index, odds ratio 1.03 (95% confidence interval, 1.01-1.05, p-value <0.0001). The linear regression model shows that both m-index and h-index were significantly positively associated with the amount of general payments (p-values <0.0001).

Conclusion

There is an association between disclosed payment from the industry and increased individual research productivity metrics. Further research to find the cause behind this association is warranted.

Project description:IntroductionThe emergence of popular online rating websites, social media platforms, and public databases for industry payments and scholarly outputs provide a complete physician online presence which may guide choice and satisfaction.MethodsWebsites of all U.S. otolaryngology academic institutions were queried for fellowship-trained rhinologists. Additional well-known and academically active rhinologists were identified by the senior author. Online ratings and comments were collected from Google, Healthgrades, Vitals, and RateMD websites, and weighted rating scores (RS) were calculated on a 1-5 scale.ResultsA total of 210 rhinologists with 16 ± 9 years of practice were included, where 6901 online ratings (33 ± 47 per rhinologist) provided an average RS of 4.3 ± 0.6. RS was not different according to gender (p = 0.58), geographic quartile (p = 0.48), social media presence (p = 0.41), or attending top-ranked medical school (p = 0.86) or residency programs (p = 0.89). Years of practice negatively correlated with RS (R = -0.22, p<0.01), and academic ranking significantly influenced RS, with professors, associate professors, and assistant professors scoring 4.1 ± 0.6, 4.3 ± 0.4, and 4.4 ± 0.6, respectively (p = 0.03). Of the 3,304 narrative comments analyzed (3.1 ± 11.6 per rhinologist), 76% (positive) and 7% (negative) had elements of clinical knowledge/outcomes, 56% (positive) and 7% (negative) of communication/bedside manner, and 9% (positive) and 7% (negative) of office staff, cost, and wait-time. All negative comment categories had moderate negative correlation with RS, while positive comment categories regarding knowledge/competence and bedside manner weakly correlated with higher RS. Number of publications (48 ± 54) positively correlated with 2018 industry payments ($11,384 ± $19,025) among those receiving industry compensation >$300 (n = 113). Attending a top-ranked medical school was associated with higher industry payments (p<0.01) and H-index (p = 0.02).ConclusionAcademic rhinologists' online RS was not associated with gender, geographic location, or attending a top-ranked training program, and their scholarly productivity was significantly correlated with total industry payments.

Project description:Background: The challenge of research funding constraints has brought to bear enormous pressure on researchers. Research productivity is relevant to prestige and career progression of academic staff. However, this study aimed to explore significant challenges associated with researchers' productivity and the impact of non-funding of research in Nigerian research and tertiary institutions. Methods: This study adopted a qualitative exploratory design involving academics at various research and tertiary institutions across the six geographical regions in Nigeria. A semi-structured questionnaire was distributed electronically to all participants who consented to take part in this study. Exactly 4,159 questionnaires were administered and 2,350 were completely filled and returned. Pearson correlation matrices with logistic regression were used for data analysis and are presented in frequencies and percentages. Results: On challenges faced by respondents, 42.98% reported a lack of research funding, 17.11% mentioned brain drain challenge while 8.85% indicated a lack of motivation. Of the 23,927 publications reported, the number of those in sciences, engineering, and medical sciences averaged 9.6, 11.5, and 9.5 respectively. The average number of publications by women (10.8) was more than by men (9.7). Lecturers had the highest average research publication number (11.8) followed by researchers (10.2) and others (3.9). Men had the highest (11.9) average number of conferences compared to women (9.2). Participants in engineering had an average number of 13.8 conferences per respondents followed by those in education (11.2), sciences (11.1), and 10.9 for those in agricultural sciences. The result revealed a negative significant correlation between research publication and academic qualification at p < 0.01. Positive significant correlation was observed between research productivity and discipline at p < 0.05. Findings show that the combined influence of the independent variables on research productivity was significant using linear regression analysis. Conclusions: The failure to prioritize research has resulted in underdevelopment in Nigeria. It is therefore imperative that the federal government prioritize research and establish a functional Special Research Trust Fund to oversee research funding in Nigeria.

Project description:PurposeAdvancing equity, diversity, and inclusion in the physician workforce is essential to providing high-quality and culturally responsive patient care and has been shown to improve patient outcomes. To better characterize equity in the field of radiation oncology, we sought to describe the current academic radiation oncology workforce, including any contemporary differences in compensation and rank by gender and race/ethnicity.Methods and materialsWe conducted a retrospective cohort study using data from the Society of Chairs of Academic Radiation Oncology Programs (SCAROP) 2018 Financial Survey. Multivariable logistic regression models were used to identify factors associated with associate or full professor rank. Compensation was compared by gender and race/ethnicity overall and stratified by rank and was further analyzed using multivariable linear regression models.ResultsOf the 858 academic radiation oncologists from 63 departments in the United States in the sample, 33.2% were female, 65.2% were White, 27.2% were Asian, and 7.6% were underrepresented in medicine (URiM). There were 44.0% assistant professors, 32.0% associate professors, and 22.8% full professors. Multivariable logistic regression analysis for factors associated with associate or full professor rank did not reveal statistically significant associations between gender or race/ethnicity with academic rank (odds ratio [OR], 0.86; 95% confidence interval [CI], 0.56-1.32; P = .48 for gender; OR, 0.81; 95% CI, 0.5-1.30; P = .37 for Asian vs White; and OR, 0.69; 95% CI, 0.31-1.55; P = .37 for URiM vs White), but CIs were wide due to sample size, and point estimates were <1. Similarly, multivariable linear regression analysis modeling the log relative total compensation did not detect statistically significant differences between radiation oncologists by gender (-1.7%; 95% CI, -6.8% to 3.4%; P = .51 for female vs male) or race/ethnicity (-1.6%; 95% CI, -7.3% to 4.0%; P = .57 for Asian vs White and -3.0%; 95% CI, -12.1% to 6.0%; P = .51 for URiM vs White).ConclusionsThe low numbers of women and faculty with URiM race/ethnicity in this radiation oncology faculty sample limits the ability to compare career trajectory and compensation by those characteristics. Given that point estimates were <1, our findings do not contradict larger multispecialty studies that suggest an ongoing need to monitor equity.
