In 2002, the peer review for the somatic indications of medical rehabilitation was further developed. This process was aimed at adjusting the peer review checklist to the "Guide for the Uniform Medical Report of the Statutory German Pension Insurance Scheme" ("Leitfaden zum einheitlichen Entlassungsbericht der Rentenversicherung"), at harmonising the peer review with the version used in the quality assurance programme of the German health insurance and at reducing requirements by focusing on criteria relevant in the individual case. This paper reports on the consensus process carried out and outlines the modifications of the peer review procedure.
