Data sourced from QOF 07/08.The sigmoid nature of many of the attainment distributions seen ( see Appendix 3, p116)results in a tension between the desire to set a target that motivates even the best performingpractices (argues for a high target) but without discouraging those poorer participating practicesfrom participation at all in the scheme (argues towards a lower target). The possibility of basingthresholds on the performance of below-median practices (for example, restricting analysis topractices lying in the lower IQR for attainment) was considered but rejected because it uniformlyresults in large numbers of better-performing practices already attaining the revised target. Theissue of providing additional rewards to practices who have not needed to make anyperformance gain is sensitive from both a financial governance and political point of view. Thiswas ultimately addressed by capping the number of NHS Hammersmith and Fulham practiceswho already exceed the QOF+ revised thresholds at four (i.e. whenever more than 4 practicesmet a candidate threshold, it was discounted.) To address the needs of poorer performingpractices for whom the thresholds may represent large jumps in attainment, it was decided thatspecific resources be made available to support them, instead of trying to revise the targetdownward.The target-setting scheme for the revised QOF+ threshold was ultimately based on an iterativeapproach that started from the 75 th national centile for QOF 07/08 (selected after analysis of themedian distances for each indicator) and revised up in 5 centile increments whenever the cappingrule described above was violated. The thresholds set by this scheme and the centiles on whichthey are based, together with the median distance and expected patient numbers aresummarised in Table A2.4. Consultation with local practices raised concerns about theconsequence of ‘all-or-nothing’ rewards on marginal errors (i.e. accidentally missing a singlepatient). To address this, an indicator-specific tolerance was introduced to provide a ‘cushion’against these errors.The tolerance is the difference between the original QOF+ threshold and a new lower thresholdcalculated using the original capping method but removing the 75 th national centile floor and the104

5-centile step. This lower value is termed the Tolerance threshold.
