Clinician-scientist training in New Zealand: historical notes and current trends

Clinician-scientist training most commonly refers to the concomitant undertaking of dual (medical and PhD) degrees by a medical student. While such training is relatively well-established in the US, Canada and many countries in Europe including the UK, uptake in Australasia has been slower and less successful. This brief piece explores this aspect, with some focus on the history of the intercalated programmes in New Zealand.

An analysis of the productivity and impact of clinical PhD theses from the University of Copenhagen

INTRODUCTION

The scientific outcome of Health Science PhD theses has been questioned by arguments suggesting that strategic motives are important for graduationamong clinical PhD graduates which may compromise scientific output and quality. This study aimed to investigate the scientific outcome of clinical PhD theses.

METHODS

A total of 841PhD theses from the Department of Clinical Medicine, University of Copenhagen, were concluded in 2013-2017. These theses were examined, and all published manuscripts were identified in online databases. Thesis bibliographics, publication activity and article/journal impact of the published manuscripts were obtained between 21 March and 18 September 2019.

RESULTS

Overall, 2,845 manuscripts were embedded in the theses (3.4 ± 0.8 manuscripts/thesis, mean ± standard deviation). A total of 56% and 92% of the manuscripts were published at the time of thesis submission and observation, respectively. The SCImago Journal Rank was 2.1 ± 1.7 and 82% of the manuscripts were published in journals with a field-specific ranking in the best quartile. The mean field-weighted citation impact of the published manuscripts was 102% higher than the world average.

CONCLUSIONS

The scientific outcome of clinical PhD theses was high as 92% of all manuscripts were published with a field-weighted journal ranking and citation impact above the world average, indicating that the productivity and quality of the clinical PhD theses are not compromised even though strategic motives is a driver for graduation.

Dissemination of PhD Dissertation Research by Dissertation Format: A Retrospective Cohort Study

PURPOSE

The study purpose was to compare dissemination of PhD dissertation research by dissertation format: traditional (five-chapter document providing a complete and systematic account of the PhD research) versus an alternate (substudy [document containing three smaller studies but not written as stand-alone manuscripts] or publication [document containing three or more related manuscripts intended for submission or published in a peer-reviewed journal]) format.

DESIGN

A retrospective study of all PhD dissertations (1999-2019) from one research intensive school of nursing.

METHODS

Following identification of graduates via the school's PhD database, we searched ProQuest and PubMed databases for the dissertation and first authored peer-reviewed publications of each graduate to determine dissertation format, study design, timing and number of dissertation research publications, and inclusion of dissertation sponsor in authorship. Data were analyzed using descriptive statistics and Wilcoxon rank sum tests.

FINDINGS

Of 113 graduates, 80 (70.8%) employed a traditional format, with the remaining graduates structuring dissertations using an alternate (substudy [n = 12], publication [n = 21]) format. Of those using the traditional format, 33 graduates (41.3%) never published dissertation research findings in a peer-reviewed journal. For those who published their dissertation research in a peer-reviewed journal, time to first publication was 1.4 ± 2.1 years (median 1.6 years) following degree conferral. In contrast, all graduates who utilized alternate formats published one or more components of their dissertation research with shorter time to first published manuscript (-0.6 ± 1.1 years; median -0.5 years; p < .001). Number of peer-reviewed publications was higher for those who utilized an alternate format compared to the traditional format (2.9 ± 1.5 [median 3.0] vs. 1.8 ± 1.1 [median 1.0], p = .001). Acknowledgment of the sponsor's contribution via publication authorship was higher for those using an alternate format compared to the traditional format (100% vs. 70.2%).

CONCLUSIONS

Number and timeliness of peer-reviewed publications stemming from dissertation research was higher for PhD graduates who utilized an alternate dissertation format. Alternate dissertation formats should be encouraged by PhD programs as one means to improve dissemination of PhD nursing research.

CLINICAL RELEVANCE

Dissemination of PhD research through peer-reviewed publications promotes the continued development of nursing science to inform nursing practice and advances the career trajectory of PhD graduates.

What Does a Modern Anatomist Look like? Current Trends in the Training of Anatomy Educators

Anatomical sciences are foundational to the health professions, yet little is known about the qualifications of anatomy educators at the graduate and professional level in the United States. Moreover, there is concern that the number of qualified anatomy educators being trained may be insufficient to meet the growing demand posed by new and expanded programs in medicine and allied health specialties. The authors surveyed anatomists from across the country to (i) characterize the educational credentials of current anatomy educators and (ii) assess the perceived need for education-focused postdoctoral positions or formal mentorships to prepare anatomists for teaching-intensive faculty positions. To probe the survey responses more deeply, one-on-one interviews were conducted with eight individuals selected to represent a diverse sample of respondents in terms of institution, gender, and academic rank. Results indicate that 30-40% of educators at the graduate level and approximately 60% of those at the undergraduate level lack graduate coursework in histology, embryology, and neuroanatomy. Forty-five percent of respondents had completed a postdoctoral fellowship. Eighty-six percent replied "yes/maybe" to the question of whether an anatomy education postdoctoral fellowship would benefit doctoral graduates. The top 3 reasons for this recommendation were to (i) establish independent educational research, (ii) improve a publication record, and (iii) gain additional teaching experience. Notable weaknesses of education-focused postdoctoral training were related to finances, fear of exploitation, and undervaluing of teaching. Moving forward, postdoctoral fellowships and other forms of postgraduate training may represent a key strategy for training anatomists in the current educational climate.

Development of Guiding Principles for a New Era in Graduate Education

Many external drivers may be influencing a paradigm shift in graduate education. Workforce dynamics are driving a re-examination of what is instructed in graduate programs as well as how curricula are delivered. Most graduate programs have made incremental changes in their philosophical approaches, but new and more dramatic paradigms may be needed to sufficiently address the future needs of employers and students alike.

Passing the Baton to the Next Generation: A Few Problems That Need Solving

This is a personal account of some of the people and factors that were important in my career in chemical oceanography. I also discuss two areas of oceanographic research and training that I think need more attention. The first is how the difficulty in getting appropriate samples hampers our ability to fully understand biogeochemical processes in the sea. I have worked on dissolved materials, suspended and sinking particles, and sediments in lakes, oceans, rivers, and aerosols. Sample collection problems affect all those areas, although to different degrees. Second, I discuss a few of the issues that I most worry about with regard to graduate education in oceanography, among them an apparent decrease over the past several decades in the ability of many beginning students to write clearly and think logically.

2017 Meeting of the National Directors of Graduate Studies in Pharmacology and Physiology

The National Directors of Graduate Studies biennial meeting is a forum for directors from pharmacology and physiology graduate programs to discuss challenges and best practices for programs that are preparing trainees to be successful in the biomedical workforce. The 2017 meeting was held on the campus of Stony Brook University in Stony Brook, NY. Over the course of the 3-day event, several themes evolved, including graduate education training and curricula, diversity and career development, and scientific rigor and communication. Overall, presentations and discussions highlighted the challenges and opportunities for training PhD biomedical scientists and featured best practices from across the country.

20 Years of Public Health Economics and Decision Sciences at the US Centers for Disease Control and Prevention: The CDC Steven M. Teutsch Prevention Effectiveness Fellowship, 1995-2015

The CDC Steven M. Teutsch Prevention Effectiveness Fellowship was started in 1995 to provide postdoctoral training in public health economics. This article describes the origins and state of the fellowship and the practice of prevention effectiveness research at the Centers for Disease Control and Prevention. The fellowship can be seen as one successful example of a demand-driven public health innovation to develop crucial capacity for the contemporary health system. Nearly 150 individuals have been trained through the program since its inception.

Evaluation of performance and perceptions of electronic vs. paper multiple-choice exams

In the veterinary professional curriculum, methods of examination in many courses are transitioning from the traditional paper-based exams to electronic-based exams. Therefore, a controlled trial to evaluate the impact of testing methodology on examination performance in a veterinary physiology course was designed and implemented. Formalized surveys and focus group discussions were also used to determine student attitudes toward the examination formats. In total, 134 first-year veterinary students and 11 PhD/MS students were administered a total of 4 exams throughout 1 semester (2 on paper and 2 electronically) using a split-halves design. The paper (P) and electronic (E) exams contained 25 identical multiple-choice questions. Students were randomly assigned to two groups and were given exams in one of two sequences (E-P-E-P or P-E-P-E). Participants consented to and completed two anonymous surveys vis à vis their experience. Out of a maximum raw score of 25, the mean score for electronic examinations (20.8; 95% confidence interval, 20.3-21.2) was significantly (P = 0.01) greater than that for paper examinations (20.3; 95% confidence interval, 20.0-20.7). However, students expressed numerous concerns with the electronic examination format, and, at the completion of the study, 87% preferred to take their examination on paper rather than the electronic format. These data show that student attitudes concerning the examination format are not primarily determined by examination results, and that the additional anxiety related to the electronic examination format plays a large role in student attitudes.

Systems biology: impressions from a newcomer graduate student in 2016

As a newcomer, the philosophical basis of systems biology seems intuitive and appealing, the underlying philosophy being that the whole of a living system cannot be completely understood by the study of its individual parts. Yet answers to the questions "What is systems biology?" and "What constitutes a systems biology approach in 2016?" are somewhat more elusive. This seems to be due largely to the diversity of disciplines involved and the varying emphasis placed on the computational modeling and experimental aspects of systems biology. As such, the education of systems biology would benefit from multidisciplinary collaboration with both instructors and students from a range of disciplines within the same course. This essay is the personal reflection of a graduate student trying to get an introductory overview of the field of systems biology and some thoughts about effective education of systems biology.

An evolution in student-centered teaching

The American Physiological Society (APS) Teaching Section annually honors an educator through its Claude Bernard Distinguished Lecture at the Experimental Biology meeting. Since I knew about my selection for almost a year, I had a long time to think about what I wanted to say and how I wanted to say it. The theme of my presentation was "nothing in education makes sense except in the light of student learning." My presentation began with a video of my "And, But, Therefore" description of my educational scholarship (see Randy Olson Great Challenges Day at TEDMED 2013, Ref. 10). "Physiology is the basic foundation of all the health professions AND physiology can be hard for students to figure out BUT many physiology courses expect students to memorize a large number of facts; THEREFORE, my scholarship is to help students learn physiology better for the long-term with various types of student-centered learning opportunities." To stress the goal of student-centered learning, my brief video was followed by a 2-min video of one of my students describing her experiences with student-centered learning in one of my two-semester Advanced Human Physiology classes. Since I have been convinced that Randy Olson is an expert on science communication (11), the rest of my presentation was the story about how I have evolved from a sage-on-the-stage lecturer into a student-centered learning facilitator. I have chosen Olson's "And, But, Therefore" approach to narrative for this written version of key aspects of the presentation.

Stability and Longevity in the Publication Careers of U.S. Doctorate Recipients

Since the 1950s, the number of doctorate recipients has risen dramatically in the United States. In this paper, we investigate whether the longevity of doctorate recipients’ publication careers has changed. This is achieved by matching 1951–2010 doctorate recipients with rare names in astrophysics, chemistry, economics, genetics and psychology in the dissertation database ProQuest to their publications in the publication database Web of Science. Our study shows that pre-PhD publication careers have changed: the median year of first publication has shifted from after the PhD to several years before PhD in most of the studied fields. In contrast, post-PhD publication career spans have not changed much in most fields. The share of doctorate recipients who have published for more than twenty years has remained stable over time; the shares of doctorate recipients publishing for shorter periods also remained almost unchanged. Thus, though there have been changes in pre-PhD publication careers, post-PhD career spans remained quite stable.

The Canadian clinician-scientist training program must be reinstated

Clinical investigators within the Canadian and international communities were shocked when the Canadian Institutes of Health Research (CIHR) announced that their funding for the MD/PhD program would be terminated after the 2015-2016 academic year. The program has trained Canadian clinician-scientists for more than two decades. The cancellation of the program is at odds with the CIHR's mandate, which stresses the translation of new knowledge into improved health for Canadians, as well as with a series of internal reports that have recommended expanding the program. Although substantial evidence supports the analogous Medical Scientist Training Program in the United States, no parallel analysis of the MD/PhD program has been performed in Canada. Here, we highlight the long-term consequences of the program's cancellation in the context of increased emphasis on translational research. We argue that alternative funding sources cannot ensure continuous support for students in clinician-scientist training programs and that platform funding of the MD/PhD program is necessary to ensure leadership in translational research.

PETE Doctoral Institutions: Programs, Faculty, and Doctoral Students

PURPOSE

The present study of doctoral physical education teacher education (D-PETE) programs was part of a longitudinal study that provided an extensive description of demographics including: (a) doctoral program characteristics, (b) faculty, and (c) doctoral students/graduates.

METHOD

This trend study incorporated 3 data sets (2005-2006, 2008-2009, and 2011-2012) that described the characteristics of D-PETE programs. Academic heads of D-PETE programs provided demographic information on their doctoral students, faculty, and institutional characteristics for the 2005-2006, 2008-2009, and 2011-2012 academic years and selected summary data from 1996-1997 through 2011-2012.

RESULTS/CONCLUSION

As a result of this longitudinal data collection, the following trends were revealed. First, there was a decrease in the number of D-PETE programs and an increase of nontenured and part-time pedagogy faculty. Second, initial teacher licensure programs remained in existence at the vast majority of D-PETE programs. Third, funding for doctoral students at D-PETE programs was decreasing. Fourth, racial composition of doctoral graduates and current doctoral students remained largely skewed toward Caucasians. Fifth, there was a slight decline in the percentage of doctoral graduates entering higher education, but employment rates were exceptionally high. Sixth, non-U.S. doctoral students and ABDs were marketable in the United States.

Implementation of an education-focused PhD program in anatomy and cell biology at Indiana University: lessons learned and future challenges

In 2008, the Indiana University School of Medicine, in collaboration with the School of Education, admitted its first student to a newly approved PhD program in Anatomy and Cell Biology focusing on educational research rather than biomedical research. The goal of the program is twofold: (1) to provide students with extensive training in all of the anatomical disciplines coupled with sufficient teaching experience to assume major educational responsibilities upon graduation and (2) to train students to conduct rigorous medical education research and other scholarly work necessary for promotion and tenure. The 90 credit hour curriculum consists of biomedical courses taught within the School of Medicine and education courses taught within the School of Education, including courses in health sciences pedagogy, curriculum development, learning theory, quantitative, and qualitative research methods, statistics, and electives. To date, 16 students have entered the program, seven have passed their qualifying examinations, and five have earned their PhD degrees. Four students have received national recognition for their educational research and four graduates have obtained faculty appointments. Going forward, we must adapt the program's biomedical course requirements to incorporate the new integrated curriculum of the medical school, and we must secure additional funding to support more students. Overcoming these challenges will enable us to continue producing a small but stable supply of doctoral-level anatomy educators for a growing academic market.
