The UCS service delivery network includes public and private facilities (though public providers
dominate as UCS covers the rural population where the private sector has a small role). Prior to
registration, private health facilities must submit documents and are assessed against standard
requirements by the NHSO. No similar process exists for public health care facilities and they
are automatically registered in the delivery network. For UCS in particular, primary care units
(PCUs) have been designated "gatekeepers", as the first contact that provides care for UCS
beneficiaries in their catchment areas. When the clinical condition requires a higher level of
care, patients are referred to secondary or tertiary health care providers.
