Regarding DHIS2 tracker

Hi Dear All

In customizing DHIS2 version 2.14 tracer for leprosy disease surveillance in Sri Lanka. The current paper based Data entry form patient diagnosed Institution captured as a data element. So in DHIS2 where I should put institution ? is it a separate Orgunit or separate patient domain data element with option set of different institution ?
