Objective To discuss the training method to promote nursing error reporting initiative and investigate its effects on nursing error and accident incidence.Methods Totally 70 nursing units in our hospital were divided into the test group and the control group with 35 units in each group.One nurse was selected from each unit in the test group to composite the training group and received tripartite training,which included the relevant theoretical knowledge lectures,group discussions and analysis,training scenarios under the guidance of professional teachers.The control group received no special training.Before and after the training,the nulpses'attitude of the erroneous theory of cultural knowledge sharing.nursing error reporting initiative.and its effects on nursing error and accident rate were investigated and compared in the two groups by paired t test.Results After the training,the nurses'sharing the erroneous theory of cultural knowledge and attitude and willingness to report nursing error were statistically different(P＜0.01).Conclusions The training method Can improve initiative and willingness of nursing error reporting,decrease nursing error and accident incidence.

Objective To assess the values of automated breast volume scanner (ABVS) for differentiating of benign and malignant breast masses.Methods A total 174 breast masses in 148 patients were subjected both to conventional handheld B-mode ultrasound (HHUS) and ABVS examinations.The masses were defined as five categories of benign,probably benign,equivocal,probably malignant,and malignant with each method.The results of ABVS and HHUS were compared with pathology.By using the definitive diagnosis and the five levels of suspicion categories,receiver operating characteristic (ROC) curves were drawn to evaluate their diagnostic results.In addition,the diagnostic accuracy for breast masses of futures including retraction phenomenon and hyperechoic rim in coronal plane of ABVS was evaluated.Results The area under the ROC curve of ABVS (0.927) was larger than that of HHUS (0.903) (Z =2.256,P =0.024).The specificity and the positive predictive values both reached to 100％ and false positive rate was 0 with retraction phenomenon,and the specificity and the negative predictive value were 88.89％ and 94.51％ respectively with hyperechoic rim in coronal plane of ABVS.Conclusions ABVS plays an important role in the clinical practice.The retraction phenomenon and hyperechoic rim of breast masses in coronal plane of this new modality have high specialty for differentiating malignant from benign breast masses.
