According to the Medical Research Council (MRC) framework, the theorisation of how multilevel, multicomponent interventions work and the understanding of their interaction with their implementation context are necessary to be able to evaluate them beyond their complexity. More research is needed to provide good examples following this approach in order to produce evidence-based information on implementation practices.

This article reports on the results of the process evaluation of a complex mental health intervention in small and medium enterprises (SMEs) tested through a pilot study. The overarching aim is to contribute to the evidence base related to the recruitment, engagement and implementation strategies of applied mental health interventions in the workplace.

The Mental Health Promotion and Intervention in Occupational Settings (MENTUPP) intervention was pilot tested in 25 SMEs in three work sectors and nine countries. The evaluation strategy of the pilot test relied on a mixed-methods approach combining qualitative and quantitative research methods. The process evaluation was inspired by the RE-AIM framework and the taxonomy of implementation outcomes suggested by Proctor and colleagues and focused on seven dimensions: reach, adoption, implementation, acceptability, appropriateness, feasibility and maintenance.

Factors facilitating implementation included the variety of the provided materials, the support provided by the research officers (ROs) and the existence of a structured plan for implementation, among others. Main barriers to implementation were the difficulty of talking about mental health, familiarisation with technology, difficulty in fitting the intervention into the daily routine and restrictions caused by COVID-19.

The results will be used to optimise the MENTUPP intervention and the theoretical framework that we developed to evaluate the causal mechanisms underlying MENTUPP. Conducting this systematic and comprehensive process evaluation contributes to the enhancement of the evidence base related to mental health interventions in the workplace and it can be used as a guide to overcome their contextual complexity.

To design, develop, deliver and assess a training initiative on haemorrhage control for emergency medical services (EMS) staff in Ukraine, in an active wartime setting.

Using the Medical Research Council framework for complex interventions, a training programme was designed and developed in a collaboration between Irish and Ukrainian colleagues and delivered by experienced prehospital clinicians/educators. Feedback was gathered from participants.

The Russian invasion of Ukraine has caused large numbers of trauma patients with limited access to advanced prehospital emergency care. Ukrainian authorities requested support in delivering such care.

Ukrainian EMS nominated clinical staff as trainees, in partnership with an educational institution in Kyiv.

One day provider and train-the-trainer courses were developed and delivered, focused on early delivery of tranexamic acid (TXA), using intraosseous access (IO) in victims of wartime trauma.

Safe organisation and delivery of courses, assessed knowledge and skills competence and self-reported satisfaction and pre/post confidence/competence.

Two provider and one train-the-trainer courses and four equipment supply exercises were delivered for 89 EMS staff (doctors, nurses, paramedics); none had prior experience of IO or prehospital delivery of TXA. All participants were assessed as competent as providers and/or trainers. High levels of satisfaction and significantly improved self-assessed confidence and competence were reported.

Rapid design and delivery of a training programme focused on an identified need for advanced care of trauma patients in a wartime setting has been possible. Training and immediate access to appropriate equipment was demonstrated. Evidence of frequency of use and safe, effective interventions has not been collected; such data are important for evaluation but difficult to collect in this setting. A high level of demand for this training now exists.
