Table 2 Pros and cons of the different methods for instituting a national UHI

From: Unique health identifiers for universal health coverage

Method of assigning a national unique health identifier Pros Cons
(1) UIN is used as UHI - Can connect with other systems, beyond the health sector - Lower cost in infrastructure and human resources - Greater potential for data breach and fraud - Not all health service users may have proof of national ID
(2) UIN and UHI are both used and linked to each other - Can connect with other systems, beyond the health sector - Lower risk of misuse of the national UIN - Higher cost of maintaining infrastructure and human resources for having two identity management systems
(3) No UIN; Only UHI is assigned - Superior confidentiality comes with limited scope and use of the UHI - UHI is used for health purposes only and not for other sectors
