Procedures for ethical review for clinical trials within the EU

When the authors of this analysis article were calculating the time that UK ethics committees took to process their application (from submission to approval), they inadvertently included some of the time required to answer the committees’ many inquiries (BMJ 2009;338:b1893, doi:10.1136/bmj.b1893). The number of days for the UK national committee in table 1 should be 119 days not 168 and the total and median (range) for the UK should be 197 (143 to 217). In table 2 the figures for national plus local approval (bottom row) should also be 197 (143 to 217). This is still considerably longer than in other countries. The authors also mistakenly stated that they had to get national approval before submitting to local committees. In fact, simultaneous approval was allowed, although experience suggested that it was more practical to do it separately.
