The trial was conducted by Tracy Taylor, a Clinical Nurse Specialist for Skin Oncology,and Dr. Judith Tanner, Lead for Nursing Research at Derby Hospitals; two very qualified investigators for the topic. The article did to systematic reviews that examined preoperative shaving; “Preoperative Hair Removal: a systematic review” by I. Kjonniksen and “Preoperative Hair Removal to Reduce Surgical Site Infection” by J. Tanner. The review of these two studies are well used throughout the article and well organized. In preparation for the study, other literature related to the topic was reviewed. The two variables identified in the article are razors and clippers. The dependant variables are preference of preoperative hair removal with razors or clippers and postoperative infections, is clearly identified in the article; the independent variables are identified as razors and clippers.
