Fleetcroft et al. (2008) 226 , estimate the potential population health gain of the full<br />

implementation of the 8 clinical interventions in both the original and the revised QOF<br />

contract. The population health gain is represented by number of lives saved per 100<br />

000 people per year. This research identified evidence <strong>for</strong> lives saved on 22 indicators in<br />

the original contract and 19 indicators in the revised one. The potential of lives saved in<br />

the original contract was 415.77 lives per 100 000 in one year. For the revised contract<br />

this number raised with 35.73 lives to a potential number of 451.5. In addition, it is<br />

important to point out that the comparator in this study was “doing nothing”, whereas<br />

there was already a significant baseline activity in primary care be<strong>for</strong>e the<br />

implementation of the QOF contract. Hence, it should be emphasized that the resulting<br />

figures represent a maximum potential. As shown in the table below, influenza<br />

immunization (in contrast with the study by McElduff et al (2004) 228 ) and primary<br />

prevention <strong>for</strong> hypertension carry the greatest potential <strong>for</strong> lives saved. It must be<br />

noted that influenza immunization was already incentivised be<strong>for</strong>e the QOF was<br />

introduced, there<strong>for</strong>e the room <strong>for</strong> improvement is rather small.<br />
