Table 2. Determinants coded to the intervention characteristics domain.

Construct	Determinant
Intervention Source	No studies
Evidence Strength & Quality	“The sentiment seemed to be shared among others in the room, who laughed and nodded, and agreed that there was a tangible disconnect between their delivery of clinical care and the ratings and scores representing their care to the public“ “As one nurse manager put it in a meeting," … it’s not about the clinical management of sepsis, it’s about fully reporting the “cookbook” steps of the goal” “clinicians repeatedly defined metric compliance as distinct to their clinical practice or scientific expertise” [18]
Relative Advantage	“Rather than containing the worst aspects of corporate activity in this sector, regulation may serve to obscure what might be widespread routine forms of injurious activity through a veil of bureaucratic compliance” [31]
	“During the discussion one of the participants (E8) mentioned that there are an estimated 3,000 non-licensed nursing homes in Portugal. “An inspection with a global closing order of all the illegal nursing homes would create an unsolvable problem: what would become of all the elderly who live there nowadays, who are roughly 25,000 to 30,000 people? There are simply not enough beds for so many people” (E8). Therefore, as mentioned by E5: “Unfortunately there is a lot of covering-up and impunity in Portugal” [32]
Adaptability	“A mandate that requires clinicians to timestamp and document secondary tasks, just to ensure metric compliance, historically is not typical for ED workflow” [18]
Trialability	No studies
Complexity	“An internist involved in quality assurance, explained that clinicians and administrators agreed SEP-1 was so complex it would need its own meeting” “His explanation echoes accounts from research at other hospitals, which confirm unprecedented complexity contributing to SEP-1’s difficulty” [18]
Design Quality & Packaging	No studies
Cost	No studies
