ABSTRACT
Objective To investigate the current status of healthcare-associated infection(HAI)and antimicrobial usage,so as to provide a scientific basis for improving the management of HAI. Methods A cross-sectional survey was conducted by combination of bedside visiting and medical records reviewing,HAI were investigated among all hospitalized patients between 0:00 and 24:00 on August 21 ,2014.Results A total of 2 216 patients were investiga-ted,the prevalence rate of HAI was 4.83% ,the case infection rate was 5.14% ;the main infection site was lower respiratory tract(63.16% ),antimicrobial usage rate was 39.71% ,the proportion of prophylactic and therapeutic use of antimicrobial agents was 32.27% and 61 .71% respectively.596 patients received therapeutic antimicrobial use,specimen detection rate was 56.21% (n= 335),the detection rate of pathogens was 15.52% (n= 52). The ma-jor detected bacteria were Pseudomonasaeruginosa,Klebsiellapneumoniae,Acinetobacterbaumannii,Escherichia coli,and Stenotrophomonasmaltophilia.Conclusion HAI prevalence survey is helpful for realizing the occurrence of HAI,respiratory tract is the main infection site,gram-negative bacteria is the major pathogen,management of prophylactic use of antimicrobial agents is the focus of HAI management.
ABSTRACT
OBJECTIVE To study the correlated factors in acquired infection of liver cirrhosis and offer more reliable theory of treatment for clinic. METHODS The liver cirrhosis history of 302 cases was retrospectively analyzed and reviewed. RESULTS From them 43 cases acquired infection during hospitalization, with 61 case-times of infection, the rate of hospital acquired infection was 14.2%, the rate of case-times of infection was 20.20%. Nineteen cases were died and the mortality rate was 44.19%, Among the 259 non-infected patients only 5 cases were died, the mortality rate was 1.93%, the difference was significant (P
