title: Application of the h-Index in Academic Plastic Surgery.
abstract: BACKGROUND
  The h-index is a measure designed to assess the quantity and significance of an individual's academic contributions. The objective of this study was to determine whether the h-index of plastic surgeons correlates with academic rank and whether there is a difference based on academic rank, residency training model, sex, geographic region, faculty size, and departmental status.
  
  
  METHODS
  A database of all US academic plastic surgeons was created. The rank and sex of each surgeon were obtained, as were characteristics of their plastic surgery program. The Scopus database was queried to determine each surgeon's h-index.
  
  
  RESULTS
  The 592 plastic surgeons in our database had a mean h-index of 8.97. The h-index increased with academic rank: 4.59 for assistant professors, 9.10 for associate professors, and 15.30 for professors. There was no significant difference in the h-index between chairpersons and chiefs. Plastic surgeons on faculty in integrated plastic surgery programs had significantly higher h-indices (9.64) than those at traditional programs (6.28). Those who were on faculty at larger programs also had higher h-indices. Male plastic surgeons had higher h-indices (9.57) than did female plastic surgeons (6.07), although this was insignificant when taking other variables into account. There was no correlation between the h-index and location or departmental status.
  
  
  CONCLUSIONS
  The h-index of plastic surgeons seems to correlate with academic rank and has potential as a tool to measure academic productivity within plastic surgery. Plastic surgeons on faculty in integrated plastic surgery programs, those at larger programs, and male plastic surgeons tend to have higher h-indices. The difference between sexes seems to be, at least in part, due to the higher number of men in high academic positions. There does not seem to be a regional difference with regard to h-indices or a difference with regard to departmental status.
