Impact Factor of NEJM

Impact Factor (IF) or often called journal impact factor (JIF) is an index provided by an analytics company named Clarivate. The impact factor is calculated by dividing the number of times the articles are cited in the last two years by the total number of publications in those two years.

For example,

  • Total Citations in 2020 and 2021 = 5000
  • Total Number of Publications in 2020 and 2021 = 500
  • Impact Factor of the Journal in 2022 = 500/100 = 10

NEJM Impact Factor (2017-2022)

  • NEJM Impact Factor 2017 – 79.258
  • NEJM Impact Factor 2018 – 70.670
  • NEJM Impact Factor 2019 – 74.699
  • NEJM Impact Factor 2020 – 91.245
