ABSTRACT
Objective:To investigate whether adjuvant skin-marker positioning can decrease the set-up errors in overweight patients with thoracic and abdominal tumors.Methods:A total of 60 overweight patients with thoracic and abdominal tumors treated with radiotherapy in the First Affiliated of Fujian Medical University between January 2018 and December 2018 were randomly divided into two groups. In group A, conventional skin-marker positioning was adopted. In group B, conventional skin-marker positioning combined with adjuvant skin-marker position was employed. All patients were immobilized with thermoplastic positioning body membrane with head-body plate fixation. The set-up errors in the right-left, head-foot and dorsoventral directions were obtained from cone-beam CT (CBCT) scan system before radiation delivery. The set-up errors were statistically compared between two groups by using t-test. Results:In group A, the set-up errors in the right-left, head-foot and dorsoventral directions were (4.47±2.91) mm, (5.43±2.61) mm and (3.87±2.40) mm, significantly higher compared with (2.97±1.68) mm, (3.21±1.62) mm and (2.59±1.57) mm, respectively (all P<0.001). Conclusion:Adjuvant skin-marker positioning method can reduce the set-up errors and enhance the positioning repeatability in overweight patients with thoracic and abdominal tumors receiving radiotherapy.
ABSTRACT
Objective To investigate perceptions of patient safety culture(PSC) among nurses in tertiary hospitals in Kunming. Methods Totally 2629 nurses were recruited by convenience sampling method from 7 tertiary hospi-tals in Kunming between July 2015 to January 2016. Hospital Survey on Patient Safety Culture (HSOPS) was used to assess PSC. Results The top three superior dimensions of PSC were Organizational Learning-Continuous Im-provement(86.60%),Teamwork within Hospital Units(83.34%) and Feedback and Communication about Error(75.98%). The last three inferior dimensions of PSC wereNonpunitive response to error(23.74%),Staffing(33.71%) and Teamwork across hospital units(49.45%). There were significant differences in certain items among nurses with different educational level,academic title,working hour per week(P<0.05). Conclusion Establishing nonpunitive re-sponse culture,reasonably arranging staffing and working hours,and encouraging nurses with high educational level and title to play their full role,are critical measures to improve patient safety culture in hospital.
