One of the most famous examples of focus is that of the Shouldice Hospital in Canada. This hospital concentrates exclusively on treating hernias using its own 'Shouldice method'. This involves using thin metal sutures, local rather than general anaesthetics, and places an emphasis on patients taking responsibility for their own care. This involves patients sharing rooms, walking to the operating theatre and (with assistance) moving off the operating table themselves. All this in the belief that encouraging movement without unnecessary discomfort in the postoperative period will help healing. What advantages do you think focusing on just one type of surgical procedure gives Shouldice Hospital?
