Abstract
Summary : Methicillin Resistant Staphylococcus aureus is resistant to all β lactam antibiotics and it can cause small abscess to life threatening sepsis or endocarditis. The risks of death in MRSA patients were three times greater than other nosocomial infections. Staff nurses without proper knowledge about MRSA, may be vulnerable to MRSA infection and dissemination. Moreover, nurses play a crucial role in preventing and controlling transmission of the infection through the application of standard precautions and maintenance of the health care environment. Therefore, nurses should be aware that MRSA infection are preventable, have up- to-date information about universal preventions that are accepted in the entire world concerning the prevention and control of infections and provide the most efficient care for patients in line with this information. Aim of the Study : This study was aimed to assess the nurses’ knowledge and practice related to methicillin-resistant staphylococcus aureus at Mansoura University Child Hospital. Research Questions. 1) Q1: what is the level of knowledge that the critical care nurses have regarding Methicillin-resistant Staphylococcus aureus? 2) Q2: what is the level of practice that the critical care nurses perform regarding prevention and control of Methicillin-resistant Staphylococcus aureus? Study design : A descriptive exploratory research design was utilized in this current study. Settings : The study was carried out in medical and surgical intensive care units affiliated to Mansoura University Children’s hospital (MUCH). Subjects : A convenience sample of seventy nurses working the previous ICUs, available during the data collection, who had at least one year of work experience in the ICU with different educational levels, involved in providing direct care for critical ill child patients and willing to participate in the current study. Tools of data collection : Two tools were constructed by the researcher to collect data pertinent to this study, those tools were :- Tool I : Interview Questionnaire Sheet. Part (1): Personal and background data sheet: it included nurses’ demographic data such as age, sex, educational level , years working of experience and attending a training program related to MRSA infection. Part (2): MRSA knowledge questionnaire sheet, It included 43 questions pertinent to Methicillin-Resistant Staphylococcus Aureus distributed as follows : 1. Knowledge related to general information about MRSA such as definition, causes, complications, colonization (14 questions). 2. Knowledge related to methods of MRSA transmission (4 questions). 3. Knowledge related to MRSA risk factors (8 questions). 4. Knowledge related to clinical signs MRSA (3 questions). 5. Knowledge related to MRSA prevention (8 questions). 6. Knowledge related to MRSA management (6 questions). Tool II : Nurses’ Practice Observational Checklist. It concerned with six domains : - • Hand hygiene (8 items). • Personal Protective Equipment (PPE) (17 items). • Laundry (5 items). • Isolation precautions (13 items). • Wound management (5 items). • Sharps (6 items). The main results of this study finding that : • The studied nurses’ age ranged between 25-35 years with mean age 27.67. • Years of experience ranged between less than one year to sixteen years with a mean of 6.60. • The majority nurses having Bachelor of nursing. • The majority of nurses didn’t attend any previous training courses related to MRSA. • Most of nurses were having an unsatisfactory knowledge and practices regarding MRSA. • There is a positive correlation between nurses’ knowledge and practices scores regarding MRSA. Conclusion : Based on the findings of the current study, it can be concluded that most of nurses were having an unsatisfactory knowledge and practices regarding MRSA. There are positive correlation between nurses’ knowledge and practices scores regarding MRSA. Recommendations : Based on results of the present study the following recommendations were suggested :- • In service training program must be developed based on nurses’ need in relation to MRSA infection control. • Periodical evaluation of nurses’ knowledge and practice regarding MRSA. • Replication of the study on a large probability sample selected from different geographical areas of Egypt. Further research: • More research should be done to investigate the barriers and the impact of nursing workload on MRSA infection and prevention.
