Objective The aim of this study was to detect the frequency of methicillin-resistant Staphylococcus aureus (MRSA) colonization at admission in a group of presumably high-risk international or Turkish patients referred to our center for elective operations, some of whom were from countries with an unknown prevalence of MRSA infection or colonization. Methods The results of nasal swab screening for MRSA colonization performed using a specific algorithm between 2011 and 2018 in a private medical center were retrospectively reviewed. Presence of MRSA was ascertained using culture and/or real-time polymerase chain reaction (real-time PCR). Results A total of 3,795 patients were included in the study. More than half of the patients were ≤19 years of age (2,094, 55.2%), and MRSA positivity was more common among these patients. Turkish patients constituted 24.5% of the study population. International patients were most frequently referred from Iraq (55.92%), Libya (11.44%), Romania (2.69%), and Bulgaria (1.98%). MRSA positivity was significantly more common among patients referred from other countries when compared to Turkish nationals (11.5% vs. 4.4%, P = 0.00001). Countries with the highest prevalence rates of MRSA colonization were as follows with decreasing order: United Arab Emirates, 25.0%; Georgia, 23.1%; Russia, 22.7%; Iraq, 13.0%, Romania, 12.7%. Other countries with high number of admitted patients (>70 patients) had the following MRSA rates: Turkey, 4.4%; Libya, 6.0%; Bulgaria, 5.3%. Conclusions Although MRSA has a low prevalence in our center, a variation in the rate of MRSA positivity was observed across patients from different countries. Absence hospital acquired contamination or outbreaks in our institution may be attributed to the screening algorithm used and underscores the importance of risk analysis for patients referred from geographical locations with unknown MRSA frequency, to reduce the risk of transmission.

“…There is a huge difference in the epidemiology of MRSA worldwide. For example, the prevalence of community-associated MRSA infection in Japan, Germany, Turkey, Taiwan, and Malta was found to be 0.94% [29], 1.2% [17], 1.2% [30], 3.8% [31], and 8.81% [6] respectively. These differences can be attributed to variations in microbiological methods (sampling technique, culture sites, and method of MRSA identification), local infection control standards, and the local prevalence of MRSA.…”

Methicillin-resistant Staphylococcus aureus (MRSA) causes purulent skin and soft tissue infections as well as other life-threatening diseases. Recent guidelines recommend screening for MRSA at the time of admission. However, few studies have been conducted to determine the prevalence and risk factors for MRSA colonization. A prospective data collection and retrospective analysis was performed. MRSA screening tests were performed using nasal swabs in patients enrolled between January 2017 and July 2018. Demographic data, socio-economic data, medical comorbidities, and other risk factors for MRSA carriage were evaluated among 1577 patients enrolled in the study. The prevalence of MRSA nasal carriage was 7.2%. Univariate regression analysis showed that colonization with MRSA at the time of hospital admission was significantly related to patient age, body mass index, smoking, alcohol, trauma, recent antibiotic use, and route of hospital admission. Multiple logistic regression analysis for the risk factors for positive MRSA nasal carriage showed that being under- or overweight, trauma diagnosis, antibiotic use one month prior to admission, and admission through an emergency department were related to MRSA colonization. This study highlights the importance of a preoperative screening test for patients scheduled to undergo surgery involving implant insertion, particularly those at risk for MRSA.

“…The profession, care unit and gender of the respondents were found to be associated with carriage rate of MRSA in this study but longer length of stay in service was not found to be associated. Socio-demographic characteristics such as age, gender, length of healthcare service and profession have been reported by previous studies to influence the carriage of S. aureus [25,26].…”

Background: Methicillin-resistant Staphylococcus aureus (MRSA) colonized healthcare workers (HCWs) constitute massive threat to the well-being of hospitalized patients due to their ability to transmit this multidrug-resistant (MDR) bacteria strain in hospital settings. Aim: To determine the prevalence of MRSA carriage/colonization among HCWs, to identify risk-factors associated with colonization/carriage, and to determine the antibiotic resistance pattern of isolates. Study Design: A cross-sectional study. Materials and Methods: A total of 333 randomly selected consenting HCWs from most hospital care units were studied. Data on demographic characteristics and infection control practices were obtained from participants with the aid of questionnaire. Swabs of the anterior nares and hands of participants were cultured on oxacillin-containing mannitol salt agar (MSA), S. aureus was identified using convectional criteria and MRSA was identified by cefoxitin disc diffusion technique. Antibiotic susceptibility testing was carried out on all isolated MRSA. Results: The carriage rate of MRSA was high (21.3%). Isolation was significantly higher among; males compared to females (P=.035), staff of critical care units compared to other care units (P=.049), among doctors and nurses compared to other HCWs (P=.0031). Poor handwashing practices (P<.001), presence of wound or skin infection (P<.001) and recent antibiotic use (P=.006) were associated with higher isolation rate. Isolation rate was higher from the nose (15.0%) than from the hands (6.3%). Isolates demonstrated low resistance to clindamycin (16.9%) and ciprofloxacin (16.9%). No isolate was resistant to vancomycin. Conclusion: In this study; colonization of HCWs by MRSA was high, a male doctor or nurse from critical care unit, with poor handwashing practices, wound or skin infection, and recent antibiotic use had a higher risk of MRSA carriage/colonization. No MRSA isolated was resistant to vancomycin. Improved infection control policies and practices are needed to curtail this trend in hospital settings.

Prevalence and risk factors for Staphylococcus aureus and methicillin-resistant Staphylococcus aureus nasal carriage inpatients in a tertiary care hospital's chest clinic in Turkey

Abstract: The prevalence of nasal carriage of MSSA was low in our study population. The only risk factors playing role in carriage were found as being under the age of 65 and having prosthesis.
