Using normalisation process theory to evaluate the implementation of a complex intervention to embed the surgical safety checklist

Abstract Background The surgical Safety Checklist (SSC) was introduced in 2008 to improve teamwork and reduce the mortality and morbidity associated with surgery. Although mandated in many health care institutions around the world, challenges in implementation of the SSC continue. To use Normalisation Process Theory (NPT) to help understand how/why implementation of a complex intervention coined Pass The Baton (PTB) could help explain what facets of the Surgical Safety Checklist use led to its’ integration in practice, while others were not. Methods A longitudinal multi-method study using survey and interviews was undertaken. Implementation of PTB involved; change champions, audit and feedback, education and prompts. Following implementation, surgical teams were surveyed using the NOrmalization MeAsure Development (NoMAD) and subsequently interviewed to explore the impact of PTB on their use of the checklist at 6 and 12 months respectively. Respondents’ self-reported perceptions of implementation of PTB was explained using the four NPT constructs; coherence, cognitive participation, collective action, and reflexive monitoring. Survey data were analysed using descriptive statistics. Interview data were coded inductively and content analysed using a framework derived from NPT. Results The NoMAD survey response rate was 59/150 (39.3%). Many (45/59, 77.6%) survey respondents saw the value in PTB, while 50/59 (86.2%) would continue to use it; 45/59 (77.6%) believed that PTB could easily be integrated into existing workflows, and 48/59 (82.8%) thought that feedback could improve PTB in the future. A total of 8 interviews were completed with 26 surgical team members. Nurses and physicians held mixed views towards coherence while buy-in and participation relied on individuals’ investment in the implementation process and the ability to modify PTB. Participants generally recognised the benefit and value of using PTB in the ongoing implementation the checklist. Conclusions Workarounds and flexible co-construction in implementation designed to improve team communications in surgery may facilitate their normalisation in practice
