Table 2 Summary of workstream 2

From: A prospective, mixed-methods, before and after study to identify the evidence base for the core components of an effective Paediatric Early Warning System and the development of an implementation package containing those core recommendations for use in the UK: Paediatric early warning system – utilisation and mortality avoidance– the PUMA study protocol

Data collection phase Aim Purpose Approach
PHASE 1: Pre-Implementation To understand current practice. To identify the micro, meso and macro contextual features consequential for effectiveness of an improvement programme. Non-participant observation of everyday practice (n = 250 h)
Interviews with staff & service managers (n = 48)
Interviews with parents (n = 32)
PHASE 2: Implementation To develop an improvement strategy tailored to each organisation. Guided by the systematic review, we will identify factors that appear to support the normalisation of changes to the Paediatric Early Warning Systems in practice and will draw on these materials to inform our improvement programme. Process evaluation with two elements;
Observational methods to describe and understand the impact of key elements of the improvement programme.
A range of methods including interviews and observations to explore experiences of, and responses to, the system changes.
PHASE 3: Post-implementation To understand the impact of the Paediatric Early Warning System improvement programme on practice. To explore in detail staff experiences of the Paediatric Early Warning System improvement programme, factors consequential for impact, and any unintended consequences. Non-participant observation of everyday practice (n = 150 h)
Interviews with staff & service managers (n = 48)
Interviews with parents (n = 32)
