programme has some limitations. First, the available empirical evidence did not provide relevant and changeable determinants for all performance objectives. It would be very useful, for example, to know which determinants affect deliberate decision making and the evaluation of pertussis vaccination in relation to personal and professional values. Any additional knowledge that is acquired from future research on these topics, however, could easily be integrated in the IM procedure presented here, and result in an update of the programme content. Second, within the scope of this study we only applied IM to the level of HCWs. As it is important in IM to address all relevant ecological levels in a final intervention, these ecological levels need attention in future studies. Additionally, the composition of the planning group was sufficient for the ecological level we chose. However, upon actual implementation, when considering all ecological levels, it is important to reconsider the members of the planning group and adjust the composition of the planning group to its specific purpose. Last, up to now it has been difficult to evaluate the proposed pertussis vaccination programme. During this project, the explicit advice for HCWs to get a pertussis booster vaccination was not yet issued by the Health Council of the Netherlands. As a result, very few hospitals or health institutions offered the vaccination to their employees at the time and a pilot test of the vaccination programme turned out unfeasible. In June 2017, the advice of the Health Council of the Netherlands to offer a pertussis booster vaccination to all HCWs who work with infants younger than 6 months became available. The implementation of this advice can now benefit from the results of this study and should additionally include the organisational determinants and all relevant ecological levels.
Conclusion
In this article we describe a detailed example of the application of IM for the systematic development of a pertussis vaccination programme for HCWs. By following the IM protocol, we were able to adjust the vaccination programme to the determinants of the target groups while considering social cognitive theories of behavioural change. We thus optimized the likelihood of the programme effectiveness if the programme should be implemented as planned.
