Acta Anaesthesiol ScandPublished Protocol for a methodological study

Study context

Population
Contemporary pilot/feasibility randomised clinical trials (RCTs) in hospitalised patients across medical and surgical specialtiestarget ≥100 RCTs
Methodological detailsdescriptive statistics, stratified by intervention type, area of care and comparator type, Search for pilot/feasibility RCTs published within the last half calendar year, expanded to a maximum of 5 years if needed to reach the minimum sample, Data extracted on trial characteristics and feasibility assessment methodology (feasibility areas, stand-alone pilot, pre-defined outcomes, pre-specified progression criteria, sample size justification, plans for definitive RCT, clinical outcomes, whether definitive trial deemed feasible)
