Objective? To explore and evaluate the effectiveness of the subspecialized fixed tutor training model on the training of the new nurses in the operating room, in order to quickly improve the competency of the new nurses. Methods? A total of 20 new nurses from July 2013 to June 2015 in Sun Yat-sen University Cancer Hospital were selected as the control group. The new nurses from July 2015 to July 2017 were enrolled in the observation group. All the new nurses relied on head nurses and the head supervisory teacher to arrange their training goals and rotation plans. According to the training plan, the control group was randomly assigned to the tutors who were on duty to be responsible for the sub-specialist surgery tour and hand washing training. When the observation team entered a sub-specialty every rotation, the fixed tutor performed one-on-one surgery tour and hand washing training. The scores and comprehensive abilities of the two groups of nurses were compared. The evaluation of the training methods by the new nurses and the satisfaction of the doctors with the new nurses were also compared across the two groups. Results? After the training, the scores of the newly recruited nurses in the theoretical knowledge, operational skills, and surgical coordination were (92.77±3.31), (94.19±2.02), and (95.27±2.55), respectively, and the control group was (90.38±2.63), (88.84±2.44), (90.35±4.92) (t=2.379, 6.891, 3.521, respectively; P＜ 0.05); The observation group's pass rate was 100.0%, and the control group pass rate was 92.5%. The difference was statistically significant (χ2=4.955, P=0.034). After the training, the scores of the new nurses' comprehensive ability in the work initiative, emergency response ability, collaborative communication ability, and learning ability were (9.45±0.21), (9.29±0.33), (9.06±0.34), and (9.08±0.24) in the observation group. The scores were (9.04±0.23), (8.78±0.33), (8.53±0.29), and (8.61±0.39), respectively, in the control group (t=5.332, 4.549, 4.938, 4.185, respectively; P＜0.001). After the training, there was no statistical difference between the two groups in the teaching content of teaching evaluation (P＞0.05). The teaching attitude, teaching method, and training effectiveness scores were higher in the observation group than the control group (t=9.854, 4.758, 9.613, respectively; P＜0.001). After the training, the satisfaction rate of the new nurses in the observation group was 100.0%, and that in the control group was 95.0%. The difference was statistically significant (χ2=12.509, P＜0.05). Conclusions? The subspecialized fixed tutor training model for newly recruited nurses in the operating room is beneficial for the new nurses to grasp the theoretical specialized knowledge in the operating room in a more solid way, to strengthen the practical operation ability of new nurses. Therefore,its implementation is worthy of promoting in the operating room.

Objective? To analyze the application effect of logistics robot in the distribution management of consumables and materials in Operating Room and to explore its application value. Methods? From December 1st to 11th in 2018, the intraoperative distribution of consumables and materials in Operating Room of Sun Yat-sen Unviersity Cancer Hospital was divided into the robot distribution group (logistic robot was used in distribution) and manual distribution group(manual power was used in distribution) based on rooms. The service time, number of service of the logistic robots and manual delivery were recorded and the incidence of logistic robots' collision was counted. Every delivery time, the error rate of the delivered goods, number and time of operation suspension for waiting for the goods in both of the two groups were counted separately and the differences between the two groups in delivery time, delivery error rate, number of times and time of operation suspension for goods waiting were compared, and the satisfaction of medical staff to the distribution of the two groups were compared. Results? Robot distribution group delivered 1 295 trips in total, with an average of 3.8 rooms per trip, and no collisions happened. In the robot distribution group, time required for each delivery(72.62±7.8) s, the error rate of delivery(0.13%), number of waiting during operation(93 times) and waiting time during operation (25.58±3.8)s were all lower than those in the manual distribution group [(160.50±20.2)s, 0.76%, 157 times, (43.75±6.8)s], with statistically significant differences(P＜ 0.01). The satisfaction of medical staff in the robot distribution group was higher than that in the manual distribution group, and the difference was statistically significant (χ2=7.103,P=0.029). Conclusions? The application of logistic robots to distribute consumables and materials in the Operating Room can partly reduce the workload of the scout nurses, reduce the waiting time in the operation, achieve swiftness and accuracy, realize intelligent management of high-value consumables, and improve the working efficiency and management quality in the Operation Room.

Methods: A total of 56 PFO patients with CS and TIA receiving device closure in our hospital from 2009-05 to 2015-12 were retrospectively studied. Transthoracic echocardiography (TTE), electrocardiogram (ECG), chest X-ray were examined at 24h, 1 month, 3 and 6 months after theoperation; telephone visit was conducted every 6 months thereafter. Results: There were 54/56 PFO patients combining CS and 2 combining TIA; 53 (94.6%)patients received PFO occluder from Starway medical technology. Aspirin was used for 6 months after the operation. The patients were followed-up for the average of (34.67±23.24) months. No body suffered from post-operative stroke and TIA; no residual shunt was observed. Conclusion: The short and mid-term efficacy of device closure has been satisfactory for treating the patients with PFO combining CS and TIA; its overall clinical value should be further investigated in large population and long-term study.

Objective To describe the current situation of pre-hospital delay and health belief in patients with colorectal cancer and explore the relationship between them. Methods With convenient sampling methods,totally 385 patients with colorectal cancer were recruited from January to June 2016. Patients with colorectal cancer were investigated using a general data survey questionnaire, visit situation questionnaire and the Champion Health Belief Model Scale. Results The median pre-hospital delay time was 3.00 months.The rate of pre-hospital delay was 43.1%(166/385). The score of the overall health belief was (119.52 ± 12.62) points. The two dimensions of"perceived susceptibility and perceived severity" scored lower, and the two dimensions of "health motivation and perceived therapeutic benefits" scored higher. The health belief was negatively correlated with the pre- hospital delay among colorectal cancer patients (r=- 0.737, P<0.01). Conclusions Pre-hospital delay occurred among patients with colorectal cancer is severe. Patients with a higher level of health belief have shorter pre-hospital delay.It′s important to improve the level of health belief of"perceived susceptibility and perceived severity"and reduce the time of pre-hospital delay to improve outcomes in patients with colorectal cancer.

Objective To understand the current situation of satisfaction and self-efficacy of nursing students in clinical practice and to explore the correlation between the two. Method A total of 120 nursing students in clinical practice were investigated using the general nursing student satisfaction scale and the general self-efficacy scale (GSES). Results The satisfaction score of nursing students was(151.89 ± 22.36)points and the score of nursing students self-efficacy was(29.06 ± 6.70)points.Nursing students self-efficacy was positively correlated with their job satisfaction (r=0.390,P＜0.01).Regression analysis showed that nursing students self-efficacy had a significant impact on job satisfaction (t=3.363,P＜0.01). Conclusion According to the characteristics of nursing students,clinical nursing education administrators should formulate and implement targeted interventions to deepen their love of nurses and improve their sense of self-efficacy,so as to enhance job satisfaction of nursing students.

Objective To describe the characteristics of nursing competence and self efficacy of new nurses in a tumor hospital and to explore the correlative relationship between them. Methods By convenience sampling method, a total of 303 new nurses who were employed in 2013 to 2015 from a tumor hospital were recruited in the study. A self-designed demographic questionnaire, the nursing competence scale (NCS) and the general self-efficacy scale (GSES) were used. Results The average score of nursing competence of new nurses was (83.80 ± 10.35) points. Among the six dimensions of nursing competence, the interpersonal relation competence had the highest score of (86.74 ± 10.55) points, while the nursing process applying competence had the lowest score of (81.41 ± 11.02) points. The level of nursing competence and each dimensions were positively related with self-efficacy (r=0.443-0.557, P<0.01). Conclusions The level of nursing competence of new nurses in a tumor hospital is good, but the nursing process applying competence, critical patient care competence and the health education competence were still insufficient, so it is necessary to take corresponding measures to improve the overall quality of new nurses. Self efficacy can effectively predict the nursing competence of new nurses. The hospital can improve the nursing competence by intervene the self efficacy of new nurses, in order to improve the clinical nursing quality and promote the development of nursing.
