The association between professional stratification and use of online sources: Evidence from the National Dental Practice-Based Research Network.

The use of online information sources in most professions is widespread, and well researched. Less understood is how the use of these sources vary across the strata within a single profession, and how question context affects search behaviour. Using the dental profession as a case of a highly stratified discipline, we examine search preferences for sources by professional strata among dentists in a practice-based network. Results show that variation exists in information search behaviour across professional strata of dental clinicians. This study highlights the importance of addressing information literacy across different levels of a profession. Findings also underscore that search behaviour and source preference vary with perceived question relevance.

Dental Blogs, Podcasts, and Associated Social Media: Descriptive Mapping and Analysis.

BACKGROUND: Studies of social media in both medicine and dentistry have largely focused on the value of social media for marketing to and communicating with patients and for clinical education. There is limited evidence of how dental clinicians contribute to and use social media to disseminate and access information relevant to clinical care. OBJECTIVE: The purpose of this study was to inventory and assess the entry, growth, sources, and content of clinically relevant social media in dentistry. METHODS: We developed an inventory of blogs, podcasts, videos, and associated social media disseminating clinical information to dentists. We assessed hosts' media activity in terms of their combinations of modalities, entry and exit dates, frequency of posting, types of content posted, and size of audience. RESULTS: Our study showed that clinically relevant information is posted by dentists and hygienists on social media. Clinically relevant information was provided in 89 blogs and podcasts, and topic analysis showed motives for blogging by host type: 55% (49 hosts) were practicing dentists or hygienists, followed by consultants (27 hosts, 30%), media including publishers and discussion board hosts (8 hosts, 9%), and professional organizations and corporations. CONCLUSIONS: We demonstrated the participation of and potential for practicing dentists and hygienists to use social media to share clinical and other information with practicing colleagues. There is a clear audience for these social media sites, suggesting a changing mode of information diffusion in dentistry. This study was a first effort to fill the gap in understanding the nature and potential role of social media in clinical dentistry.

Temporal search persistence, certainty, and source preference in dentistry: Results from the National Dental PBRN.

OBJECTIVES: The primary goal of this paper was to investigate an old question in a new way: what are the search patterns that professionals demonstrate when faced with a specific knowledge gap? METHODS: We examine data from a cascading survey question design that captures details about searching for information to answer a self-nominated clinical question from 1027 dental professionals enrolled in the National Dental Practice Based Research Network. Descriptive and conditional logistical regression analysis techniques were used. RESULTS: 61% of professionals in our sample choose informal sources of information, with only about 11% looking to formal peer reviewed evidence. The numbers of professionals turning to general internet searches is more than twice as high as any other information source other than professional colleagues. Dentists with advanced training and specialists are significantly more likely to consult peer-reviewed sources, and women in the sample were more likely than men to continue searching past a first source. CONCLUSIONS: Speed/availability of information may be just as, or in some cases, more important than credibility for professionals' search behavior. Additionally, our findings suggest that more insights are needed into how various categories of professionals within a profession seek information differently.

Association between predoctoral evidence-based practice training and later use of peer-reviewed journals: National dental PBRN.

OBJECTIVE: We examined whether evidence-based practice (EBP) during dental school was associated with the increased use of peer-reviewed literature during subsequent clinical practice for National Dental Practice-Based Research Network (PBRN) dentists. We also sought to understand whether this association was moderated by being a dental specialist. METHODS: We analyzed cross-sectional data from 1228 dentists participating in the PBRN. We used logistic regression to examine the association between self-reported EBP training during dental school and the use of peer-reviewed journals in clinical practice, controlling for the number of years since dental school graduation and dental practice type. We stratified the data by dental specialists and examined effect modification using the Breslow-Day test for homogeneity of the odds ratio. RESULTS: The prevalence of peer-reviewed journal use by PBRN dentists in clinical practice was 87% (n = 1070) with no statistical evidence of effect modification by dental specialists on the EBP peer-reviewed journal use relationship (p > 0.05). After controlling for years since dental school graduation and dental practice type, dentists who self-reported EBP training during dental school had greater odds of using peer-reviewed journals in clinical practice than dentists who did not self-report EBP training during dental school (OR, 1.47; 95%CI = 1.01, 2.15). CONCLUSION: The use of peer-reviewed published literature by PBRN dentists who had EBP predoctoral training is one important step in the EBP process by which practicing dentists can implement evidence-based findings, interventions, and policies into routine health care and public health settings. These findings add to the body of support for EBP curricula in dental education.

A characterization of professional media and its links to research.

The publishing industry is a vast system whose elements form a metaphorical ecosystem with knowledge flowing through connections between heterogeneous elements. In this paper we seek a more robust understanding of different types of literature, and whether and how they support one another in the diffusion of knowledge. We analyze a corpus comprising professional electronic media in US dentistry and its relation to the peer reviewed journal literature. Our corpus includes full text from magazines, news sites and blogs that provide information to clinicians. We find links to research are made through several mechanisms: articles describing new clinical guidelines, referencing, summaries of recently published journal articles and crossover authoring. There is little to no apparent time lag in the diffusion of information from research literature to professional media.

Preferences for peer-reviewed versus other publication sources: a survey of general dentists in the National Dental PBRN.

BACKGROUND: Medical professionals have access to a broad range of resources to address clinical information needs. While much attention is given to new sources of data such as those available on the internet, it is less clear how clinicians choose between peer-reviewed research literature and other publication-based sources. This analysis distinguishes between possible drivers of publication type preference (namely, practice setting, advanced training, professional development experiences). Dentists enrolled in the National Dental Practice-Based Research Network (PBRN) are the population for this study. Theories of human and intellectual capital and institutional logics theory are used to understand how advanced training and other clinical experiences may explain the choices that dentists make when faced with clinical questions. METHODS: An online questionnaire was implemented with general dentists in the US National Dental PBRN. A series of logistic and Ordinary Least Squares (OLS) regression models were used to explain the use of peer-reviewed and other publications. Measures of knowledge-based human capital distinctions (advanced clinical training and research engagement, advanced professional status, personal motivation for professional advancement) were used to explain preferences for research literature as a clinical resource. RESULTS: General dentists with advanced training, as well as those with a skill advancement motivation, show a preference for peer-reviewed materials. General dentists who have been practicing longer tend to favor other dental publications, preferring those sources as a resource when faced with clinical challenges. Human capital and professional motivation distinguish the information preferences among general dentists. Further, these factors explain more variance in use of peer-reviewed materials than practice setting does. Few differences by demographic groups were evident. CONCLUSIONS: Results point to a distinct variation in the general dentistry professional community. Advanced training among general dentists, as well as the types of procedures typically conducted in their practice, distinguishes their information preferences from other general dentists, including those with more years of clinical experience.

Missed Opportunities for Detecting Alternative Nicotine Product Use in Youth: Data From the National Dental Practice-Based Research Network.

PURPOSE: With growing rates of youth e-cigarette and hookah use, and the fact that use of these products is difficult to detect, surveillance and early detection efforts need to be reassessed. Physicians and pediatricians both report that their level of knowledge about these products is low. Given that over 80% of youth have had dental visits in the past year and that the effects of nicotine use are visible early in routine dental examinations, it is likely that dental professionals are well positioned to play a critical role in detection. Currently, the knowledge about alternative nicotine among practicing dental clinicians is unknown. METHODS: One thousand seven hundred and twenty-two dental professionals in community practice in the United States National Dental Practice-Based Research Network responded to a survey in the summer/fall of 2016. These data were supplemented with network membership enrollment data, and the American Community Survey, and were analyzed using descriptive statistics, measures of association, and logistic regression. RESULTS: Only 25%-36% of dental professionals feel knowledgeable about the most common types of alternative nicotine products, including e-cigarettes and hookahs. Thirty-eight percent of respondents reported not screening at all for e-cigarettes. CONCLUSIONS: A substantial percentage of dental professionals do not have a working understanding of alternative nicotine products, nor are aware of their patients' use rates. Better access to information and training on alternative nicotine products could provide an opportunity to improve surveillance for early use of these products in youth populations.

Take me where I want to go: Institutional prestige, advisor sponsorship, and academic career placement preferences.

Placement in prestigious research institutions for STEM (science, technology, engineering, and mathematics) PhD recipients is generally considered to be optimal. Yet some doctoral recipients are not interested in intensive research careers and instead seek alternative careers, outside but also within academe (for example teaching positions in Liberal Arts Schools). Recent attention to non-academic pathways has expanded our understanding of alternative PhD careers. However, career preferences and placements are also nuanced along the academic pathway. Existing research on academic careers (mostly research-centric) has found that certain factors have a significant impact on the prestige of both the institutional placement and the salary of PhD recipients. We understand less, however, about the functioning of career preferences and related placements outside of the top academic research institutions. Our work builds on prior studies of academic career placement to explore the impact that prestige of PhD-granting institution, advisor involvement, and cultural capital have on the extent to which STEM PhDs are placed in their preferred academic institution types. What determines whether an individual with a preference for research oriented institutions works at a Research Extensive university? Or whether an individual with a preference for teaching works at a Liberal Arts college? Using survey data from a nationally representative sample of faculty in biology, biochemistry, civil engineering and mathematics at four different Carnegie Classified institution types (Research Extensive, Research Intensive, Master's I & II, and Liberal Arts Colleges), we examine the relative weight of different individual and institutional characteristics on institutional type placement. We find that doctoral institutional prestige plays a significant role in matching individuals with their preferred institutional type, but that advisor involvement only has an impact on those with a preference for research oriented institutions. Gender effects are also observed, particularly in the role of the advisor in affecting preferred career placement.

The unbearable emptiness of tweeting-About journal articles.

Enthusiasm for using Twitter as a source of data in the social sciences extends to measuring the impact of research with Twitter data being a key component in the new altmetrics approach. In this paper, we examine tweets containing links to research articles in the field of dentistry to assess the extent to which tweeting about scientific papers signifies engagement with, attention to, or consumption of scientific literature. The main goal is to better comprehend the role Twitter plays in scholarly communication and the potential value of tweet counts as traces of broader engagement with scientific literature. In particular, the pattern of tweeting to the top ten most tweeted scientific dental articles and of tweeting by accounts is examined. The ideal that tweeting about scholarly articles represents curating and informing about state-of-the-art appears not to be realized in practice. We see much presumably human tweeting almost entirely mechanical and devoid of original thought, no evidence of conversation, tweets generated by monomania, duplicate tweeting from many accounts under centralized professional management and tweets generated by bots. Some accounts exemplify the ideal, but they represent less than 10% of tweets. Therefore, any conclusions drawn from twitter data is swamped by the mechanical nature of the bulk of tweeting behavior. In light of these results, we discuss the compatibility of Twitter with the research enterprise as well as some of the financial incentives behind these patterns.

The "new normal": Adapting doctoral trainee career preparation for broad career paths in science.

Doctoral recipients in the biomedical sciences and STEM fields are showing increased interest in career opportunities beyond academic positions. While recent research has addressed the interests and preferences of doctoral trainees for non-academic careers, the strategies and resources that trainees use to prepare for a broad job market (non-academic) are poorly understood. The recent adaptation of the Social Cognitive Career Theory to explicitly highlight the interplay of contextual support mechanisms, individual career search efficacy, and self-adaptation of job search processes underscores the value of attention to this explicit career phase. Our research addresses the factors that affect the career search confidence and job search strategies of doctoral trainees with non-academic career interests and is based on nearly 900 respondents from an NIH-funded survey of doctoral students and postdoctoral fellows in the biomedical sciences at two U.S. universities. Using structural equation modeling, we find that trainees pursuing non-academic careers, and/or with low perceived program support for career goals, have lower career development and search process efficacy (CDSE), and receive different levels of support from their advisors/supervisors. We also find evidence of trainee adaptation driven by their career search efficacy, and not by career interests.
