MICROBIOLOGIC CAUSES OF INFECTION
Culture of the surgical site in 60 of 61 infected
patients yielded growth of organisms (a total of
107 isolates), and similar proportions of infected
patients in the two study groups (23 of 39 [59%]
in the chlorhexidine–alcohol group and 37 of 71
[52%] in the povidone–iodine group) had an identifiable
microbiologic cause of infection (Table 4
in the Supplementary Appendix). Gram-positive
aerobic bacteria (63 isolates) outnumbered gramnegative
aerobic bacteria (25 isolates) by a factor
of 2.5, and 38% of cultures were polymicrobial.
There were no significant differences in the frequency
of isolating certain categories of organisms
or particular organisms in the chlorhexidine–alcohol
group (total of 44 isolates) as compared with
the povidone–iodine group (total of 63 isolates),
with the exception of streptococci, which were less
common in the former group (1 of 44 [2.3%] vs.
10 of 63 [15.9%], P = 0.03).
ADVERSE EVENTS
In the intention-to-treat analysis, adverse events
occurred in equal proportions among the patients
in the chlorhexidine–alcohol group and the povidone–
iodine group (228 of 409 [55.7%] and 256
of 440
