Qualitative content analysis of key informant interviews—intervention Consolidated Framework for Implementation Research domain

Qualitative content analysis themes	Clinician type	Relevant topic	Site adherence
Facilitator
Agreement that low tidal volume strategies are most appropriate for ARDS patient care	RT, P	LPV, CDS	L, M, H
Perception that use of a protocol provides certain advantages when treating patients with ARDS	P	CDS	L, M, H
Agreement that LPV CDS tool is easy to use once trained	RT, P	CDS	L, M, H
Belief that use of the protocols reduces physician time on ventilation management activities	P	CDS	L, M, H
Belief that LPV CDS tool use increases self-efficacy and confidence implementing an LPV strategy treating ARDS patients	RT	CDS	H
No need for significant changes in the technology design of the LPV CDS tool	RT, P	CDS	L, M, H
Barrier
Resentment to adopting a care process they did not assist locally in selecting and developing	RT, P	LPV, CDS	L, M
Belief that LPV strategies can include initial tidal volume settings > 6.5 ml/kg PBW	RT, P	LPV	L
Perception that patients sometimes cannot tolerate low tidal volumes (patient-ventilator dis-synchrony)	RT, P	LPV	L, M
Belief that use of the tool increases time spent on documentation activities for each patient	RT	CDS	L, M
Discomfort with specific instructions from the LPV CDS tool given patient’s circumstances	RT, P	CDS	L, M
Perception that LPV CDS tool use does not facilitate a quick and efficient response to patient needs	RT	CDS	L, M
Perception that it is not easier to initiate a low tidal volume setting using the LPV CDS tool versus no tool	RT	CDS	L, M, H

Clinician type—respiratory therapist (RT) and physician (P); relevant topic—lung-protective ventilation (LPV) and clinical decision support (CDS) tool; site adherence—low (L), medium (M), and high (H)
