From the April 25, 2011 New York Times article Better Hand-Washing Through Technology:
"Data really helps us work backwards,” said Katherine Ellingson, an epidemiologist at the Centers for Disease Control in the Division of Healthcare Quality Promotion. "If hospitals can identify wards that have problems or wards that are doing very well, they can learn where the gaps are or how people have found a way to get adherence up. And when people have data, they pay attention. The CEO may pay attention. The health workers themselves will pay attention if you provide data on their performance.”
I have mixed feelings about this. I agree with Ellingson that data helps people pay attention, but do we really need electronic policing to elicit behavior that is such a fundamental part of being a caring human? In the Positive Deviance MRSA work, staff on the unit were engaged in active surveillance, deciding how to measure results, and how to feed back data. I suspect that when people are fully engaged, there is little need for expensive high-tech monitoring, and more occasions for celebration.
My two cents' worth
