RESUMEN
Objective:To analyze the effect of SBAR (situation, background, assessment, and recommendation) sign-out template in the standardized residency training in a neonatal ward.Methods:Based on SBAR communication mode, we designed and optimized neonatal ward sign-out checklist, and a total of 67 residents were trained for 2 weeks from April 2019 to June 2019, with control group (before training) and observation group (after training). The assessment indicators of sign-out information included sign-out duration, the incidence of sign-out errors, quality assessment scores and shift satisfaction (including sign-out satisfaction and self-evaluation) as well as competencies. A total of 1 553 children's morning shift data were collected, and SPSS 22. 0 was used for t test and chi-square test. Results:In the control group, the sign-out duration was (23.4±4.7) min, the incidence of sign-out errors was (43.6±6.6)%, quality assessment scores were (6.3±0.7) points, the satisfaction degree was (76.5±4.6)%, and the self-evaluation scores were (5.2±2.1) points. While, in the observation group, the sign-out duration was (15.9±3.2) min, the incidence of sign-out errors was (21.1±2.3)%, quality assessment scores were (8.9±0.9) points, the satisfaction degree was (94.1±2.9)%, and the self-evaluation scores were (8.9±0.8) points, with statistically significant difference ( P<0.05). There were statistically significant differences between the two groups in clinical skills and medical service ability [(2.2±0.1) vs. (3.8±0.3)], interpersonal communication ability [(2.6±0.5) vs. (4.2±0.1) points], teamwork ability [(3.1±0.2) vs. (4.6±0.3)], information and management ability [(2.5±0.5) vs. (4.2±0.2)] ( P<0.05). Conclusion:The SBAR template can improve sign-out process and the clinical skills of standardized training residents.
RESUMEN
Objective To develop a high performance liquid chromatographic method (HPLC) for the analysis of of cholesterol in erythrocyte membranes.Methods The study included 167 consecutive chest pain patients who underwent coronary artery angiography in the Department of Cardiology,Nanjing General Hospital of Nanjing Command between September 2012 and February 2013.According to the clinical symptoms and t angiographic results,patients were divided into three groups:acute coronary syndrome (ACS) group (n =46),stable angina pectoris (SAP) group (n =76) and the control group (n =45).After the erythrocyte sample was hypotonically lysed and washed,saponification was carried out in a polassium hydroxide solution at 70 ℃.After extraction by Hexane/isopropanol mixture,the sample was separated on a Lichrospher column and detected by ultraviolet absorbance at 208 nm.A mobile phase composed of acetonitrile-isopropyl alcohol was found to be the most suitable for this separation.Concentrations of cholesterol in erythrocyte membranes were tested.Analysis of variance with covariates (ANOVA) was used to evaluate differences in CEM levels among groups.The relationship between continuous variables was evaluated by Spearman's correlation coefficient.Results Under the chromatographic conditions described,retention time of the cholesterol was approximately 6.1 min.Good separation and detectability of cholesterol in erythrocyte membranes were obtained.The method proved to be linear in the injection range of cholesterol from 0.05 g to 2.00 g.Cholesterol content in erythrocyte membranes were (87.0 μg/mg,75.4-98.9 μg/mg),(92.9 μg/mg,83.8-109.0 μg/mg) and (173.9 μg/mg,140.0-188.8 μ g/mg) in the control,SAP and ACS groups,respectively.Cholesterol content in erythrocyte membranes was significantly higher in ACS group than that in SAP and control groups (P ＜ 0.01).Conclusion We have successfully developed a method for the determination of cholesterol in erythrocyte membranes with good sensitivity,specificity and repeatability.
