The Defense Health Agency (DHA) intends to award a sole source contract to Nihon Kohden America, LLC for the procurement of a Polysomnograph Polybed Complete with PSG 1100, specifically for use at Misawa Air Base. This system is crucial for conducting Level 1 sleep testing for over 280 patients annually, thereby minimizing the need for off-base referrals for sleep studies. The sole source justification is based on Nihon Kohden America, LLC being the only approved provider due to an existing Authority to Operate (ATO) for their PSG system. Interested vendors challenging this sole source intent must submit a capability statement by August 12, 2025, to Barrett Taylor at barrett.s.taylor.ctr@health.mil, as this notice is not a request for competitive proposals.
