摘要：Introduction: Hospital infections prolong patient hospitalization, necessitate additional treatment, increase mortality rate, raise hospital expenses, and even reduce the level of health in the society. The purpose of this research was to study hospital infections in selected hospitals of Qazvin. Methods and Materials: This was an analytic-cross-sectional study. The research population consisted of 25,628 hospitalized patients in the first eight months of 2012 in three selected hospitals of the Qazvin Province. The algorithm of reporting hospital infections, the National Program of Controlling Hospital Infections, and 223 patient files hospitalized due to hospital-acquired infections were used to collect information. The collected information was analyzed using the SPSS V. 17 software; the descriptive statistics was used to analyze the qualitative variables; and the descriptive statistics together with chi-square and t-test were employed for the quantitative variables. Results: The ICU units had the most cases of hospital infections. Respiratory pneumonia and urinary infections topped the list of hospital infections. The most invasive treatments carried out on patients with hospital infections were surgery, urinary catheter, and venous catheter, respectively. More than 50 percent of patients with hospital infections were hospitalized for 2 to 21 days. Results and Conclusions: Because of the high rate of hospital infections, especially in the ICU ward, authorities must give top priority in their plans to designing suitable educational programs to inform hospital staff and patients of hospital infections and to provide suitable resources for dealing with this problem.
