Introduction: Evolution of antibiotic resistant bacteria poses a major threat to public health. All patients are entitled to a non-infectious care environment; despite the fact that infectious transmission in health care is possible. Prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in patients, staff and in health care environment represents such a threat.
In infection prevention in health care established routines in patient care, handling of medical equipment and cleaning in care environment are essential.
Aim: The aim of the study was to assess the fraction of MRSA positive environmental sampling following terminal cleaning of a room where a patient with confirmed MRSA was treated, and to assess whether potential patient’s risk factors and/or length of hospital stay influenced the result.
Methods: Quantitative study with consecutive material consisting of data from in total 180 environmental samplings performed in Region Halland. The material has been processed with the statistic program SPSS, and analyzed with Chi2 test.
Results: In 14 % (25 out of 180) of the environmental samplings MRSA was detected. A statistically significant association between prevalence of patient risk factors as wounds/skin lesions, drainage, catheters, tracheostomy or other artificial body openings could not be shown. However, a hospital stay exceeding 24 hours significantly increased risk of detecting MRSA in the patient room after terminal cleaning.
Conclusion: Quality of terminal cleaning is important in preventing transmission of MRSA in health care environment and probably more important than the impact of patient risk factors. However, length of hospital stay is a factor worth consideration and can possibly be used to influence care routines in prevention of transmission of MRSA in health care environment.
