    Implementation and engineering science and the costs of revising and rolling out hand hygiene programmes

    Dear Editor
    Ross and co-authors have developed a usable model to estimate the costs of hand hygiene in household settings for the 46 least developed countries. (1)

    The authors conclude that costs could be covered by using resources from across government and partners, and could be reduced by “integrating hand hygiene with other behavioural change campaigns where appropriate.” (1) Models such as these are based on the assumption that gathering up all the relevant costs has been done – yet the authors note that “follow-up formative research to revise promotion interventions based on implementation experience was not included.” Their justification was that the cost of these revisions would be likely to be small.

    However, implementation and engineering science suggest that the costs of such revisions could be major. If there were problems with the original plan for promotion interventions, then multiple steps would be needed to enable their revision. These would include but would not be limited to understanding the problems, identifying what factors were causing the problems, planning a strategy for change and then tactics on how such change could be delivered, testing the change, and then rolling it out.

    When all these are taken into account, the cost of the revision process could be considerable and to this must be added the cost of the new implementation strategy that would then need to be rolled out.

    Thus, a new implementation strategy...
