Patterns of beta-lactam prescription in patients with unconfirmed allergic reactions to penicillin. The cross-reactivity between penicillin and other beta-lactams was mainly concerned among Thai physicians when prescribing aminopenicillin and the different decision making between allergists and non-allergists was significantly observed when prescribing first or third/fourth generations of cephalosporins (data represent percentages of each group, ∗∗ represents P values < 0.01 between allergists and non-allergists, gen ceph: generations of cephalosporin, A: allergists, and N: non-allergists).
