“…The contemporary or h c -index adds an agerelated weighting to each cited article, thus correcting for the property of the h-index never decreasing with time, even if the researcher is no longer publishing. Our data show that the spread of h c -index values is not as great from instructor to chairman (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17) as it is for the h-index . This indicates that a significant proportion of the h-index for senior neurosurgeons is due to the ability to continue reaping citation benefits from dated publications that are not yet available to younger neurosurgeons.…”

Object Bibliometrics is defined as the study of statistical and mathematical methods used to quantitatively analyze scientific literature. The application of bibliometrics in neurosurgery is in its infancy. The authors calculate a number of publication productivity measures for almost all academic neurosurgeons and departments within the US. Methods The h-index, g-index, m-quotient, and contemporary h-index (hc-index) were calculated for 1225 academic neurosurgeons in 99 (of 101) programs listed by the Accreditation Council for Graduate Medical Education in January 2013. Three currently available citation databases were used: Google Scholar, Scopus, and Web of Science. Bibliometric profiles were created for each surgeon. Comparisons based on academic rank (that is, chairperson, professor, associate, assistant, and instructor), sex, and subspecialties were performed. Departments were ranked based on the summation of individual faculty h-indices. Calculations were carried out from January to February 2013. Results The median h-index, g-index, hc-index, and m-quotient were 11, 20, 8, and 0.62, respectively. All indices demonstrated a positive relationship with increasing academic rank (p < 0.001). The median h-index was 11 for males (n = 1144) and 8 for females (n = 81). The h-index, g-index and hc-index significantly varied by sex (p < 0.001). However, when corrected for academic rank, this difference was no longer significant. There was no difference in the m-quotient by sex. Neurosurgeons with subspecialties in functional/epilepsy, peripheral nerve, radiosurgery, neuro-oncology/skull base, and vascular have the highest median h-indices; general, pediatric, and spine neurosurgeons have the lowest median h-indices. By summing the manually calculated Scopus h-indices of all individuals within a department, the top 5 programs for publication productivity are University of California, San Francisco; Barrow Neurological Institute; Johns Hopkins University; University of Pittsburgh; and University of California, Los Angeles. Conclusions This study represents the most detailed publication analysis of academic neurosurgeons and their programs to date. The results for the metrics presented should be viewed as benchmarks for comparison purposes. It is our hope that organized neurosurgery will adopt and continue to refine bibliometric profiling of individuals and departments.

“…10,11,[22][23][24][25] It has been used to predict overall influence of senior scientists and has been shown to be a strong predictor of academic rank in radiology and urology. 11,22 These same data illustrate the variability between specialties, as a full professor of urology has a mean h-index of 22, while a full professor of radiology has a corresponding h-index of only 12.5.…”

“…11,22 These same data illustrate the variability between specialties, as a full professor of urology has a mean h-index of 22, while a full professor of radiology has a corresponding h-index of only 12.5. Choi et al 10 describe a mean h-index of 8.5 for radiation oncologists, compared to mean h-index of Kulasegarah and Fenton 25 of 15 for otolaryngologists. CAM practitioners have not yet provided a comprehensive distribution of the h-index among CAM scholars, but rather describe "a few prominent" CAM researchers, with h-indices of 21 to 38.…”

“…For example, in a study of radiation oncology, the mean h-index was 8.5, with a breakpoint of 15 between junior and senior faculty. 10 Yet in a study of urology, the mean h-index for full professors was only 10.7, with associate and assistant professors at 6.9 and 6.2, respectively. 11 It is therefore essential that the h-index distribution for any given specialty be adequately characterized so that accurate and generalizable conclusions can be drawn about an individual's place within the distribution (e.g., is this person on a par with other individuals up for promotion to associate professor in their specialty?…”

The Distribution of the H‐index Among Academic Emergency Physicians in the United States

Background: Hirsch's h-index (h) attempts to measure the combined academic impact and productivity of a scientist by counting the number of publications by an author, ranked in descending order by number of citations, until the paper number equals the number of citations. This approach provides a natural number or index of the number of publications and the number of citations per publication. H was first described in physics and was demonstrated to be highly predictive of continued academic activity, including recognized measures of scientific excellence such as membership in the National Academy of Sciences and being a Nobel laureate. Citation rates, research environments, and years of experience all affect h, making any comparisons appropriate only for scientists working in the same field for a similar time period. The authors are unaware of any report describing the distribution of h among academic emergency physicians (AEPs).

“…None of these studies included a nonanesthesiologist control group, but similar analyses of radiation oncologists and faculty in neurosurgery and urology suggest anesthesiologists publish less often than do these other specialists. [7][8][9] Cardiothoracic anesthesia may be an exception; faculty members from 30 randomly selected cardiothoracic anesthesia fellowship programs contributed 28 ± 46 publications on average, with senior faculty having more than junior faculty and ACGME-accredited fellowship program faculty having more than those in nonaccredited programs. 2 Still, the 15 faculty directing non-ACGME cardiothoracic anesthesia fellowships had 20 ± 24 publications, 2 which is several fold more than the directors of ACGME-accredited core anesthesia residency programs included in our study.…”

Academic Productivity of Directors of Accreditation Council for Graduate Medical Education-Accredited Residency Programs in Surgery and Anesthesiology

Survey of Anesthesiology

Background-Scholarly activity is expected of program directors of the Accreditation Council for Graduate Medical Education (ACGME)-accredited residency training programs. Anesthesiology residency programs are cited more often than surgical programs for deficiencies in academic productivity. We hypothesized that this may in part reflect differences in scholarly activity between program directors of anesthesiology and surgical trainings programs. To test the hypothesis, we examined the career track record of current program directors of ACGMEaccredited anesthesiology and surgical residency programs at the same institutions using PubMed citations and funding from the National Institutes of Health (NIH) as metrics of scholarly activity.
