RQ frequency and standard procedure required

Dear members,

Can anyone suggest any solution for elemination of OQ in RQ (this RQ is exclusisvely carried out as once in 3 years for all manufacuting equipments).

Is it sufficient that I check the history of the equipment for any changes (through change control), incidents, PMP, calibrations, breakdowns and then comment that the equipment is in qualififed state?

Or do i need to perform OQ again besides the above and confirm? I want to eliminate this OQ which we follow in our company as the equipment is used daily for operation and performance is also checked by the testing of the batch being processed.

Can any one guide what should be the RQ frequency in the above case and whether is it really required to do OQ in RQ or what is the standard practice for performing RQ of equipments to say that they are in qualified state
