“…However, notwithstanding the commonly accepted perceptions by governments (El-Jardali et al, 2008) and healthcare professionals (Diab, 2011;El-Jardali et al, 2008) on the benefits of accreditation; existing evidence is either modest Lutfiyya et al, 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 r n a l o f H e a l t h O r g a n i z a t i o n a n d M a n a g e m e 3 2009) or inconclusive (Bogh et al, 2015;Braithwaite et al, 2010;Dean Beaulieu and Epstein, 2002;Greenfield and Braithwaite, 2008;Miller et al, 2005;Shaw et al, 2010;Thornlow and Merwin, 2009), particularly regarding its impact on the quality of care.
