This study was also quantitative, with MRSA screening being an independent variable. Methods similar to previous study methods were used in this research, including monitoring post-surgical ICU patients who received a nasal swab before surgery. The population of this study included patients treated postoperatively in the ICU. Exclusion criteria were not specified. The study analyzed data collected from the observation of 614 patients treated in intensive care between April 2006 and March 2011. The patient population was divided into two groups: MRSA positive (31 patients with an average age of 73.5 +/- 1.9 years) and negative for MRSA. (583 patients with a mean age of 68.3 +/- 0.5 years). The MRSA-positive group included 23 men and 8 women, while there were 390 men and 193 women in the MRSA-negative group. The researchers then compared the incidence of postoperative MRSA infections in the two groups. All postoperative study subjects received a nasal swab consecutively processed using double nutrient agar with chemical sensitivity to identify MRSA. Patients identified as MRSA positive were treated with appropriate antibiotics. Empirical antibiotic treatment was used in cases where MRSA was strongly suspected but culture results had not yet been positive. Besides tools like nasal swabs, agar
