Guide For Use: Each PSO shall be identified by a unique Object Identifier (OID). The unique OID for each PSO shall be created using a combination of the PSO Root OID (2.16.840.1.113883. and the PSO ID (e.g. P0023) assigned by AHRQ to each PSO.

The AHRQ assigned unique PSO ID for each PSO begins with the letter P, followed by 4 numeric characters e.g. P0023. The PSO ID is assigned to the PSO upon official listing by AHRQ.

The PSO shall create their PSO OID using the following convention:

The numeric value (not including any preceding zeros) of the PSO ID is appended to the PSO Root OID (2.16.840.1.113883. The PSO Root OID and the numeric value of the PSO ID shall be separated by a period. For example, the PSO OID for a PSO with an AHRQ-assigned PSO ID of P0023 would be: 2.16.840.1.113883.
