NIH’s Office of the Director, Office of Acquisitions intends to award a non-competitive firm-fixed-price purchase order to Inova Health Care Services for access to patient samples and associated clinical data supporting the NHLBI Critical Care Research Program. Performance will rely on Inova Fairfax Hospital in Fairfax, VA, which has established infrastructure to consent, enroll, collect, and transfer samples to NIH within 48 hours of patient admission. The requirement is a renewal of an existing contract, and pausing sample collection to build equivalent infrastructure elsewhere would be detrimental to the program. The acquisition uses NAICS 622110 and is not set aside for small business.
