  • Background: The updated data regarding prevalence of healthcare-associated infections (HAIs) in a middle-income country is lacking. 

    Methods: A point prevalence survey with a total time frame of 10 days was conducted among 50 hospitals in Thailand across the country in January 2014, including 19 primary hospitals, 15 secondary hospitals, 13 tertiary hospitals, 2 private hospitals, and 1 university hospital. 


    Of 15,475 patients, 688 patients with 791 HAIs (1.1 HAI per infected patient) were reported. The prevalence of patients with at least one HAI was 4.4% (95%CI=4.1-4.8%), including 7.3% (95%CI=4.6-9.3%) in university hospitals, 5.0 (95%CI=4.6-5.4%) in tertiary hospitals, 3.9 (95%CI=3.4-4.6%) in secondary hospitals, 2.0 (95%CI=1.3-2.7%) in primary hospitals, and 1.6 (95%CI=0.5-2.8%) in private hospitals. The most frequently patient wards reported HAI included intensive care unit (17%). The two most affected age ranges were >60 years and <1 year. Among 791 HAIs, the most three frequently reported HAI type were 377 (48%) respiratory tract infections, 176 (22%) urinary tract infections, and 55 (7%) surgical site infections. Of 688 patients with HAIs, 24% died after three months of the survey. The most frequently reported bacterial pathogens were 17% Acinetobacter species. By multivariate analysis, HAIs were associated with age <1 year, university hospital, major surgery, urinary catheterization, having respiratory ventilator, tracheostomy tube insertion, and central venous catheterization (all P <0.05). Death was associated with age <1 year, university hospital, surgical and medicine wards, having respiratory ventilator, and central venous catheterization (all P <0.05).

    Conclusion: Healthcare-associated Infections remain the major public health problems in the country. In addition, it leads to a substantial mortality.
