The Clinton Health Access Initiative, Inc. (CHAI) is a global health organization committed to saving lives and improving health outcomes in low- and middle-income countries by enabling the government and private sector to strengthen and sustain quality health systems.

The Clinton Health Access Initiative, Inc. (CHAI) Cambodia invites interested and capable organizations to submit proposals to contribute to the design of the evaluation protocol and to lead data collection, analysis, and reporting for a retrospective evaluation of the Hub-and-Spoke Medical Oxygen Delivery and Supply Model implementation in Kampong Cham Province, Cambodia. The selected organization (hereinafter, the “Offerors”) will work in structured collaboration with CHAI at all stages of the evaluation, from protocol finalization through to final reporting. The full terms of this engagement, including the division of responsibilities between the Offerors and CHAI, are detailed in the Scope of Work (Section G) and the Evaluation Protocol (Annex B).

Access to medical oxygen remains a critical and persistent gap across health systems in low- and middle-income countries. In Cambodia, systemic shortfalls in oxygen supply, marked by cylinder shortages, non-functional concentrators, and heavy dependence on costly private suppliers were significantly exposed during the COVID-19 pandemic. In response, the Royal Government of Cambodia and development partners made substantial investments in domestic oxygen generation infrastructure (PSA plant), increasing from 2 to now 64 PSA plants across the country.
