A group of nine patient organisations told Mr Lansley that patients needed to know whether doctors are fit to practise and urged Mr Lansley not to delay the roll out of revalidation.
The organisations issed a statement covering six themes, including: patient expectations, the GMC's role, the future development of revalidation and patients' role in providing feedback.
‘Revalidation will be an important statement that a doctor is competent in their area of practice,' the organisations said. 'We recognise the contribution that revalidation can make over time to the quality and safety of care that patients receive.'
The statement added: 'We trust that the secretary of state for health will make this decision with the views and interests of patients paramount by ensuring there is no further delay in revalidating doctors’ licences.'
Reacting to the statement, GMC chief executive Niall Dickson said: ‘We welcome the support of the nine patient organisations as it shows the importance of revalidation to patients across the UK.
'This is what patients expect to happen and these organisations are rightly calling for no further delay.’
The nine organisations signing the statement of support were:
• National Voices
• Patients Association
• National Association of LINks Members
• National Association for Patient Participation
• Academy of Medical Royal Colleges Patient/Lay Group
• Action against Medical Accidents
• Scotland Patients Association
• Board of Community Health Councils in Wales
• Patient and Client Council (Northern Ireland)
