A primer on leading the improvement of systems.

But today, when I entered the room, the mother handed me her up to date list of treatments, including nebuliser treatment with ß2 agonists, that she had administered with equipment that had been installed in her home. It continued with her graph of Jimmy's slowly improving peak flow levels, which she had measured and charted at home, having been trained by the asthma outreach nurse. She then gave me the nurse's cellular telephone number, along with a specific recommendation on the next medication to try for her son, one that had worked in the past but was not yet available for her to use at home.
