BACKGROUND AND OBJECTIVESUsually, infections that appear in the patient's body ۴۸ to ۷۲ hours after the patient's admission to the hospital are considered hospital infections. Pseudomonas aeruginosa bacteria have a high prevalence rate in various types of wounds, such as burns, bedsores, diabetic foot ulcers, etc. Hospital-acquired infections resulting from these wounds are a major cause of morbidity and mortality in patients. The aim of this study is to investigate the, during the years ۱۴۰۱ and ۱۴۰۲ in Motahhari burn hospital and Firuzabadi Hospital in Rey city.MATERIALS AND METHODSIn the conducted study, all ۲۰۰ patients of Motahhari Burn Hospital and Firuzabadi Hospital in Rey, between the years ۱۴۰۱ and ۱۴۰۲, were examined and studied. They were evaluated based on the type of wound (burn, bedsore, diabetic ulcer), wound grade, wound depth, infection quantity, age, gender, wound percentage and quantity, duration of hospitalization, and the season under investigation.RESULTS AND DISCUSSIONOut of ۲۰۰ patient samples, ۴۸ patients (۲۴%) were found to have Pseudomonas aeruginosa infection. The amount of Pseudomonas aeruginosa infection increased during the spring and summer seasons when the weather was warmer. The rate of Pseudomonas aeruginosa infection was higher in bedsores (۴۰.۸%) compared to burns (۳۰.۲%), and higher in burns compared to diabetic ulcers (۲۹%).CONCLUSIONBased on the conducted studies and research, adherence to standard infection control principles is essential in hospitals. Factors such as wound type, season, and the prevalence of Pseudomonas aeruginosa should be considered in hospital infection control programs.
