Surgery will become less safe, and malignancy treatment can be more difficult. To estimate the hazard posed to modern medicine by antibiotic level of resistance, the researchers examined hundreds of clinical trials between 1968 and 2011 that examined the effectiveness of antibiotics in preventing infection after chemotherapy or 10 common surgical procedures. Those procedures included hip fracture surgery, pacemaker implantation, medical abortion, spinal surgery, hip replacement, C-section delivery, prostate biopsy, appendectomy, hysterectomy and colon surgery. Based on their review, the researchers estimate that among 39 % and 51 % of medical site infections and 27 % of post-chemotherapy infections are caused by bacteria already relatively resistant to antibiotics.
