Only following death, halves the brute damage that accumulates on a carbon mob. This is in response to a discussion about post-mortem surgeries taking too long under circumstances where mitigating tools are unavailable.
Rather than buff any of medical's options, or force resleeving with the return of the much-maligned husking mechanic (or something similar) this quality of life change should not increase someone's survivability at all, but will reduce ridiculously-long surgery times to something more reasonable under the most common extreme-damage circumstance.
