Max-ICH score

Created 08/06/2022, last revision 08/06/2022

  • the easy-to-use and reliable tool to predict unfavorable long-term (12-month) functional outcome and death after intracerebral hemorrhage
  • ICH involving both lobar and non-lobar regions should be scored according to the location that ICH most likely originated from
  • if there are 2 distinct ICHs (1 large lobar and 1 large non-lobar) in one patient, then the patient would be assigned more than 1 point referring to the ICH volume
  • the highest max-ICH total score = 9 points
  • each 1-point increase in the max-ICH score was associated with an OR of 1.24 for an unfavorable outcome  (Suo, 2018)
  • external validation comparing the ICH score and max-ICH score shows a similar prognostic performance (Schmidt, 2018)
