      Both the TRISS and ISS/Age methods have been used to assess the mortality results in a series of injured patients. Though observed survival was not significantly different from that expected using TRISS, the method seemed to place too great an emphasis on the initial clinical signs summarized in the RTS. In particular, early cardiovascular signs can be variable and misleading. The TRISS calculation also seems to make inadequate allowance for age effects in the elderly.
      The simpler ISS/Age method is free from these difficulties and with further development and a more up-to-date base series might become a better basis for overall survival estimates.
