In its response to the GMC's consultation on revalidation, the RCGP said concerns about additional workload and bureaucracy were a 'common theme' in its members' responses.
GPs have not be reassured by the GMC's promise that revalidation will not be 'bureaucratic or costly', it said.
'Several members argued that recording and reflecting in writing on their continuing professional development (CPD) was often more time consuming than doing the CPD in the first place, and that revalidation was certain to lead to a greater diversion of GPs from their primary responsibilities,' it said.
The response, which was submitted by RCGP's honorary secretary of council Professor Amanda Howe, also said that many GPs have concerns over how GPs who wanted to take career breaks would be revalidated.
It outlined that 16 out of 60 respondents raised concerns about how revalidation would apply to those GPs with gaps in their services, either through maternity leave, travelling abroad for charity work and those with portfolio careers.
'Many of these felt that revalidation as a process was heading towards a homogenised general practice, in which those pursuing more individual career paths would be squeezed out, deliberately or by default, by the practical requirements of the process,' the response said.
Meanwhile, the RCGP said it would welcome details from the GMC about how local systems for revalidation would be 'sufficiently quality assured'.
It also said the responsible officer (RO) role must be accountable and local systems robust, and that ROs must make decisions fairly.
