The power of habit
While on the ID consult service last week, I walked out of a patient's room, and wiped down my stethescope. Halfway through that action, I realized that I had not used my stethoscope on the patient. I was thrilled! The stethoscope wipedown had become a habit, since I demonstrated a key characteristic of habits: automaticity. I didn't think about it. I walked out of the patient room and my cue (crossing the threshold of the room) prompted me to automatically sanitize my stethoscope. Just like sitting down in the seat of a car prompts me to latch my seatbelt.
If you haven't read The Power of Habit by Charles Duhigg, I highly recommend it. From the book I learned that 40% of our daily activities occur without any active decision making. These activities are habits. The trick, of course, is for us to figure out how to get hand hygiene and stethoscope wipedown established as habits. We need more psychologists working with us in infection prevention since the field is increasingly dependent on influencing the behaviors of healthcare workers.
