I use 5MCC powered by Skyscape and my PDA as a "sales" tool. I have long expressed that we doctors, and especially we Emergency doctors, are and must be salespeople in the truest sense of the word. Our target audience is tough- they are tired, in pain, vomiting and sick of waiting. Frequently, the patient/customer is accompanied by a frustrated and skeptical family member. To these customers we must sell our professional judgment in terms of a diagnosis and a treatment plan that studies show under the best of circumstances are rarely followed. In this particular case, a patient expressed her skepticism over my diagnosis of panic disorder. Then came the dreaded "but how do you know, doctor?" I calmly replied, "Why don't we just consult the computer". I brought forth my PDA, accessed 5MCC powered by Skyscape, and then Panic disorder and began to read from the list of associated signs and symptoms. After several rounds of my naming and her nodding ascension, the sale was closed with the statement, "I guess you were right doctor."
