Adding EHR data and functionality is costly

• Potential for increased data gathering burden– Additional time– Altered workflow

• Necessary Design/Development costs– Systems must be re-configured to accommodate

new data/functionality• Who absorbs these costs?

“Why, What, How, and By Whom”• Why:

– Well-articulated Problem/Need/Goal ... to which additional information/functionality are a clear solution

• What:– Identify information needed to accomplish the goal

• How:– Define process. Re-use existing resources before

asking for more: Identify and leverage potential pre-existing measures that address the need.

“Why, What, How, and By Whom”• Who:

– Contemplate who may be optimally positioned to gather/supply new information• Physician• Nurse• Registration Clerk• Patient• Other?

Define Metrics to Assess Progress Toward Goal

Integrating Community level and Geospatial data

“Why”: Integrating Community level geospatial data

• Socio-behavioral factors are important, often unrecognized determinants of health outcomes

• US healthcare system is oriented to acute, hospital based, disease treatment.

• Responding to the health needs of both non-hospitalized and hospitalized patients with chronic diseases is proving difficult.

• Improving population level health problems like healthcare disparities is also challenging, in part because of the complex interplay of socio-behavioral, community and biologic factors within the context of the current healthcare system.

• Just as IT enabled advances in sub-molecular medicine, behavioral and population sciences are on the verge of an IT based revolution.

Population Trends

A network diagram illustrating the connectedness among Indiana EDs that participate in PHESS. Circular nodes represent EDs; node size indicates the visit volume; node color indicates the centrality of the ED. The gray edges connecting nodes indicate where patient crossover occurs. EDs that share proportionally larger number of patients are clustered together. While general clusters of "medical trading areas" emerge, the myriad gray edges clearly illustrate how interconnected all EDs are to one another.

84% PPV for predicting which patients who will use ED > 16 times in two years.
