Element | Method | Indicative measures/details |
---|---|---|
Theory-based evaluation of factors along the proposed causal pathway | Quantitative | Intervention and control group: scales in endpoint surveys (see Table 4) |
Delivery of intervention components | Mixed | Intervention group: detailed assessment of NET intervention delivery |
Local opinion leaders: researcher-assessed presence of both opinion leaders in each hospital for entire intervention delivery duration | ||
Stakeholder meeting: attendance of providers; delivery of messages and so forth (researcher assessed) | ||
Train-the-trainer: observer assessment of intervention components | ||
Local educational workshops: education sessions provided assessed via log-books completed by the clinical opinion leaders | ||
Materials and tools: availability assessed via self-report clinical opinion leaders and staff | ||
Control group: high-level assessment of potential delivery of (non-NET) intervention components assessed via a brief telephone interview with ED Director or delegate (for example, was someone in your ED championing improvements/providing education around the management of mTBI patients?) | ||
Receipt and acceptability and feasibility of intervention elements | Mixed | Intervention group: |
Local opinion leaders: inclusion ‘local opinion leaders’ scale (ORCA) in staff endpoint surveys; staff perceptions of ‘availability’ and ‘credibility’ (in semi-structured interviews) | ||
Stakeholder meeting: attendance of key-stakeholders; acceptance of messages (both researcher assessed) | ||
Train-the-trainer: attendance of local opinion leaders assessed via attendance lists; participant assessment of acceptance of components (participant sheets) | ||
Local educational workshops: attendance of local staff assessed via attendance lists; participant acceptance of sessions provided, assessed via scales in endpoint surveys and semi-structured evaluation interviews | ||
Materials and tools: availability assessed via self-report of local opinion leaders and staff | ||
Perceptions around successful implementation | Qualitative | Intervention group: Perceptions around the success of the implementation assessed in semi-structured interviews |
Perceptions of factors influencing successful implementation | Mixed | Intervention group: Perceptions around factors influencing the implementation processes (for example, organisational readiness; perceived leadership support; perceptions around quality and clarity of evidence and recommendations and so forth, measured in semi-structured interviews) |
Inclusion of ‘leadership’ scale (ORCA) in staff endpoint surveys | ||
Perceptions of acceptability and feasibility intervention as ‘package’ | Mixed | Intervention group: Perceptions around usefulness and feasibility of roll-out measured in semi-structured interviews |
