Structured Assessment of FEasibility (SAFE)

What is SAFE?

Structured Assessment of FEasibility (SAFE) is a measure designed to assess the feasibility of implementing a complex intervention within mental health services within the NHS. The measure is designed for reviewers and policy makers when assessing the evidence base for an intervention and for researchers developing an intervention to ensure they consider factors related to implementation. SAFE was developed as part of the REFOCUS programme at King’s College London.

SAFE reporting guidelines were also developed, to identify the information needed in intervention reports which will allow SAFE to be rated. These reporting guidelines are intended to be used by authors reporting an intervention, to make it possible for the feasibility of the intervention to be assessed.

Downloading SAFE

The above paper included SAFE Version 1.0 as an appendix. Subsequent evaluation identified the need for minor modifications (SAFE Version 1.1) and a rating manual to further improve the reliability of SAFE ratings.

Scoring SAFE

The measure can be completed by systematic reviewers, commissioners, managers and researchers. There are 16 questions in two sections. The first eight questions assess blocks to implementation, with the final eight questions assessing facilitators of implementation. Best practice recommends against using summary scores on assessments to categorise papers within a systematic review, since items within the scale may have unequal weight. Instead it is recommended that reviewers attend to the individual items of the scale when conducting sensitivity and sub-group analyses. This same approach has been adopted for scoring SAFE – the reviewer rates individual items, without providing an overall summary score.

As an example of using SAFE, it has been applied to evaluation of the feasibility of recovery interventions:
