After a successful visit to Dublin in 2015, the biennial Global Implementation Conference (GIC) 2017 recently took place in Toronto, Canada on the 20th-21st of June. Ireland’s implementation research community was well represented amongst over 500 other delegates, with approximately 20 Irish participants, including representatives from the Centre for Effective Services, Health Service Executive, NUI Galway, University College Cork and the HRB-Trials Methodology Research Network. QUESTS Education Working group member Dr Elaine Toomey of the Health Behaviour Change Research Group, NUI Galway was also in attendance, presenting work on the use of mixed methods for assessing intervention fidelity (i.e. the degree to which an intervention was put into practice as intended by its developers). This research was completed by Dr Toomey as part of her recently completed PhD research in University College Dublin and highlighted the value of using qualitative and quantitative methods involving all stakeholders to ensure that fidelity assessments are both feasible and comprehensive. For more information on this work, see previous publications here. More of this research is also currently in press in BMJ Open and will be available soon!
