The indicators PCET and PCVE varied little, with almost 100% conformity throughout the sample, whereas the PCDO and PCCP presented good internal consistency with a variation of 0.67 to 0.80; discriminant validity showed higher average scores of conformity and were statistically significant in the group of institutions with accreditation; in the validation of the construct it was possible to differentiate 2 dimensions for PCDO (1-recommendations for prevention of HI and 2- recommendations for the standardization of prophylaxis procedures), with good correlation of the units of analysis that composed it. The same occurred for PCCP (1-interface with treatment units and 2-interface with support units). All of the indicators, except the PCCP, which ranged from 9.5% to 100%, presented scores of > 90%, which show that the HICPPs of participating hospitals have a good standard of quality, with higher average scores in the institutions with accreditation.
