Many medical procedures (which are less or more necessary) like LASIK, joint replacement, tonsillectomy or gallbladder removal are described for patients as very safe (usually with a high number of successful previous procedures taken around the world).
Are there concrete standard for the safety of such procedures? Number of deaths, for example, is not enough. A scale of severity of side effects would be more the direction.
I hoped for something like the Injury Severity Score but it seems that there isn't. I understand the subjectivity of this question. But is there a way to classify medical procedures in a way so that a man that undergone a gallbladder removal will know that tonsillectomy is easier b/c the recovery is usually shorter + the probability of hematoma is lower etc? Or maybe the side effects vary so much that there is no way to compare procedures which are not very similar(e.g. one in dentistry and on in gastro).
