Testing a systematic approach to identify and prioritise barriers to successful implementation of a complex healthcare intervention

Table 1 Target behaviours with summary of number of barriers and ranking scales

Target behaviour	Number of barriers	Ranking scale range (influence) (Higher rank = lower influence)	Ranking scale range (difficulty) (Higher rank = least difficult)	Completed by professional group
Triaged as ATS Category 1 or 2	6	1–6	1–6	EN, EDr, SDr
Full assessment for rt-PA eligibility	9	1–9	1–9	EN, EDr, SN, SDr
All eligible patients receive rt-PA	9	1–9	1–9	EN, EDr, SN, SDr
Temperature taken on arrival	5	1–5	1–5	EN, EDr, SN, SDr
Treatment with paracetamol	4	1–4	1–4	EN, EDr, SN, SDr
Finger prick BGL on admission	2	1–2	1–2	EN, EDr, SN, SDr
Administration of insulin	7	1–7	1–7	EN, EDr, SN, SDr
NBM until a swallow screen^a	8	1–8	1–8	EN, SN, SP
Discharged to SU within 4 h^b	4	1–4	1–4	EN,SN,BM

Note: The definitive T³ trial intervention consists of 12 clinical care elements. The questionnaire included only 9 clinical care elements due to the following reasons:
The clinical care element ‘venous BGL sent to lab on arrival to ED’ was not included due to limited evidence on barriers for this element
^a = broad heading for 2 sub-set of clinical care elements
^b = broad heading which combines 2 sub-set clinical care elements
