The drivers of HTA decisions

Decision making by NICE: examining the inuences of evidence, process and context

Two reductionists views can be avoided. There is one that puts all the eggs in one basket of QALYs, the opposite that considers that QALYs are flawed and the solution is far away. Beyond such extremes, there is the need to assess new techonogies, and this is precisely what NICE does. An interesting article revisits the current drivers used by NICE to take decisions. These are the conclusions:
The results suggest that the variability in decisions observed can be explained by a combination of clinical, economic, process and socio-economic factors. The analysis showed that the proportion of restrictions and non-recommendations issued by NICE are increasing over time relative to recommendations. The analysis also confirmed that the demonstration of clinical and economic value is central to NICE decisions.

New factors not previously reported to have an effect on NICE decision making were identified, including the effect of clinical superiority on NICE decision making, the effect of the ICER on the likelihood of both restriction and recommendation and that NICE decision making was sensitive to process variables as well as socioeconomic factors.
Interesting guide to convince those that already have a reductionist mind. The evidence, the process and the context has to be taken into account.
