title: Positive associations of nosocomial infections in surgical ward with etiological clinical factors.
abstract: This study was conducted in the surgical wards of Dhaka Medical College Hospital, Bangladesh (General Surgery Wards and burn unit) on nosocomial infection. Thirty percent of the study patients, of which, elderly patients constitute 62.5%, were infected with nosocomial infection. Among those patients, wound infection (38.7%) was the most common type of nosocomial infection, from which about 63.5% belonged to postoperative. The other common types were acute respiratory tract infection (19.2%), urinary infection (26.6%), and gastro-intestinal infection (12.5%). In this study, it was found that combined infection (36%), pseudomonas (33%) as well as E. coli (17%) had the greatest contribution of developing postoperative wound infection. Nosocomial infection was not significantly associated with sex distribution, but was significantly higher in postoperative patients (63.5%) than preoperative (36.5%). Another significant finding of this study was that there was a strong positive association between the frequency of nosocomial infections and increasing number of visitors per patient per day) (Tab. 6, Fig. 4, Graph 2, Ref. 26).
