The h-index was introduced as a means of quantifying the contribution a researcher makes to the scientific literature. We evaluated the h-index for academic neurosurgeons to assess the various methods of calculation and to determine whether the h-index can be used to differentiate groups of individuals by various classifications. ⋯ Application of the h-index as a bibliometric in neurosurgery can distinguish academic productivity on the basis of academic rank, years posttraining, and neurosurgical subspecialties. The application of the h-index to compare departments is problematic and, at this time, not reliable.

To review suitable measures of patient-assessed outcome of surgery for spinal metastases, and suggest the Health-Related Quality of Life measures that are useful and practical for this group of patients. ⋯ We recommend the use of the EQ-5D measure in research for assessment of patient-centered outcomes and calculation of cost effectiveness of surgery for spinal metastases. Routine use of the measure in clinical practice is also encouraged, because it is a simple and quick method to assess overall clinical outcome.

The widely accepted h-index depends on the citation analysis source and does not consider the authorship position, the journal's impact factor (IF), or the age of the paper or author. We investigated these factors in citation statistics of academic neurosurgeons. ⋯ Google Scholar tends to inflate the h-index. The m-quotient and hc-index allow comparisons of researchers across time. Although average journal IF did not differ significantly among neurosurgeons academic ranks, it should be noted for individuals who consistently publish in high-impact journals. We recommend the creation of individual bibliometric profiles to better compare the academic productivity of neurosurgeons.
