Myriad studies have shown that clinical decision support can reduce medical errors and improve healthcare quality in both inpatient and ambulatory settings. However, only a small number of sites (generally academic medical centers and large integrated delivery networks) make significant use of the most advanced and effective decision-support interventions. Community hospitals and independent healthcare providers generally make only limited use of decision support, in fact frequently opting to disable it entirely in their clinical systems. This lack of use stems from a variety of causes, ranging from technical to political to economic; however, perhaps the main cause is resources: academic medical centers and integrated delivery networks are more likely to have clinical decision support committees and in‐house development resources. In this dissertation, I introduce a new approach to sharing decision-support content that leverages existing work toward developing a National Health Information Network (NHIN).
