Table 1 Response scales used by the Delphi Panel for rating the importance, operational feasibility, and political feasibility of solutions to medication non-adherence

From: Developing consensus-based policy solutions for medicines adherence for Europe: a delphi study

Important scale Operational feasibility scale Political feasibility scale
1. Not at all important 1. Definitely unfeasible 1. Definitely politically unfeasible
− Unlikely to have impact on non-adherence − Cannot be implemented − Politically unacceptable
− Not at all confident about effectiveness of solution − Unprecedented allocation of resources would be needed − Completely unacceptable to the public
− Basic research needed
2. Slightly important 2. Probably unfeasible 2. Probably politically unfeasible
− Potential for impact on a minority of patients − Some indication that this cannot be implemented − Major political obstacles
− Not very confident about effectiveness of solution − Large scale increase in available resources would be needed − Not acceptable to a large proportion of the general public
− Major research effort needed
3. Somewhat important 3. May or may not be implemented 3. May or may not be implemented politically
− Potential for impact on some patients − Contradictory evidence that this can be implemented − Political obstacles
− Unsure about effectiveness of solution − Increase in available resources would be needed − Some indication that this may not be acceptable to a large proportion of the general public
− Indeterminable research evidence available
4. Very important 4. Probably feasible 4. Probably politically feasible
− Potential for impact on majority of patients − Some indication that this could be implemented − Some minor political obstacles
− Quite confident about effectiveness of solution − Available resources would have to be supplemented − Further consideration may have to be given to public reaction, although some evidence exists that the proposed solution may be acceptable
− Some research still required
5. Extremely important 5. Definitely feasible 5. Definitely politically feasible
− Potential for widespread general impact − Can be implemented − No major political obstacles
− Very confident about effectiveness of solution − Necessary resources (financial, labour etc) are presently available − Will be acceptable to the general public
− No further research required
  1. The importance rating scale was adapted from Hardy et al. [15], while the feasibility scales were adapted from Adler and Ziglio [10].
