Finding #2
Doctors in most studies also preferred that nurses performed only non‐medical tasks.
Assessment for each CERQual component
Methodological limitations	Minor concerns because 3 studies did not report reflexivity; 2 studies did not report ethical consideration; and 2 studies did not report sampling strategy.
Coherence	Moderate concerns because all studies welcomed the transfer of certain tasks to nurses, but only in 1 study doctors were not willing to shift tasks such as examination, diagnosis or therapy to nurses. Moreover, in LMICs, attitude among doctors was reported to be more mixed.
Relevance	Minor concerns because most data were from HICs and there were 2 studies from LMICs.
Adequacy	No or very minor concerns.
Overall CERQual assessment
Moderate confidence	Due to minor concerns about methodological limitations and relevance; and moderate concerns about coherence.
