简要总结
Surgical hand scrubbing is the removal of transient flora and reduction of permanent flora as much as possible before any sterile gloves are worn before any surgical intervention. It is a cheap and easy method to prevent infections. Effective use of surgical hand scrubbing has an important role in preventing and reducing the transfer of health-related infections. Although many studies have been performed on surgical hand scrubbing, no standard practice has been found in the method of scrubbing and optimal duration of scrubbing time. The aim of this study is to compare evidence-based surgical hand scrubbing methods in order to prevent surgical site infections.
Methods H0: There is no difference between the effectiveness of different surgical hand scrubbing methods on the bacterial flora in the hand H1: There is a difference between the effectiveness of different surgical hand scrubbing methods on the bacterial flora in the hand.
Time H0: There is no difference between the effectiveness of different the duration of scrubbing time on the bacterial flora in the hand.
H1: There is a difference between the effectiveness of different the duration of scrubbing time on the bacterial flora in the hand.
详细描述
Original Value: Surgical site infections (SSI) are a serious problem due to increased morbidity and mortality, prolonged hospitalization, hospitalization and consumption of health resources. It is reported from guides that the several factors like hair removal, skin antisepsis, prevention of hypothermia, antimicrobial prophylaxis, providing adequate oxygenation applied in intraoperative period reduce SSI. In addition to these factors, it is known that hand antisepsis of the surgical team is one of the most important factors in preventing SSI. Surgical hand scrubbing is the removal of transient flora and reduction of permanent flora as much as possible before any sterile gloves are worn before any surgical intervention. It is a cheap and easy method to prevent infections. Effective use of surgical hand scrubbing has an important role in preventing and reducing the transfer of health-related infections. Therefore, the research topic is directly related to patient safety and is considered to be one of the important areas of health services at national and international level in terms of establishing institutional culture in the prevention of surgical site infections. Although many studies have been performed on surgical hand scrubbing, no standard practice has been found in the method of scrubbing and optimal duration of scrubbing time. The aim of this study is to compare evidence-based surgical hand scrubbing methods in order to prevent surgical site infections.
Method: The research is a randomized controlled prospective study. The universe of the research was surgeon and operating room nurses in Gulhane Training and Research Hospital. The sample size is at least 180 people for one-way analysis of variance with G * Power version 3.1.19 software to determine a medium level (0.25) effect size between 4 groups at 0.80 power and 0.05 type I error level calculated (Tsai, 2016). Participants was divided into 4 groups by randomization method.
The participants in the first group performed the surgical hand scrubbing for 1 minute and with using a nail brush.
The participants in the second group performed the surgical hand scrubbing for 1 minute and without using a nail brush.
The participants in the third group performed the surgical hand scrubbing for 2 minute and with using a nail brush.
