NICE health technology appraisal decisions can be categorised into four types:
Recommended: To be made available to all patients considered within the scope of the appraisal
Restricted: To be made available to a sub-group of patients relative to the scope of the appraisal
Not recommended: Not recommended for use by any patient relative to scope
Terminated: Appraisal not complete and decision not reached
Figures 1 and 2 – NICE decisions
The number of decisions that are not recommended have increased since 2000. Around two-thirds of decisions restrict use in a sub-population of the relevant group of patients, and just over one quarter are recommended.

Figure 2 shows the trend in reported outcomes of NICE decisions, from 2000–2012.
