RESUMEN
【Objective】 This study endeavors to introduce the statistical process control (SPC) method to analyze the quality control index concerning red blood cells in additive solution with leukocytes reduced, with the aspiration to advance the effective utilization of blood quality control data, thereby providing empirical foundations for the continual enhancement of blood quality. 【Methods】 Between 2020 and 2022, test data pertaining to the quality control index of red blood cells in additive solution with leukocytes reduced were amassed from six blood stations in Chongqing area. Utilizing Minitab software, the SPC analysis was carried out, p-control charts were delineated, the non-conformance rates of each quality control index along with their 95% confidence intervals were computed, as well as the Process Capability Index (Z value). 【Results】 In accordance with the Whole Blood and Blood Components Quality Requirements, the appraisal of the quality control indexes for red blood cells in additive solution with leukocytes reduced manifested a conformity rate of 100% for appearance, end-of-storage hemolysis rate and sterility test. Nonetheless, the conformity rates for volume, hemoglobin, hematocrit and residual leukocytes did not attain 100%, albeit all were ≥75%. Through the employment of binomial distribution-based p-control charts, the controlled state of the production process was discerned. Although the overarching conformity rate satisfied the national standard stipulations, it was discerned that there were out-of-control points concerning volume, hemoglobin, hematocrit, and residual leukocytes across different institutions, exhibiting palpable trends. The non-conformance rates of all quality control indexes were less than 25%, yet at a 95% confidence level, the residual leukocyte counts from institutions B, C, E, and F did not adhere to the stipulations (exceeding 25%). By architecting the ability evaluation index Z value for count data process capability analysis, it was unveiled that the volume of institution E, the hematocrit of institutions B, C, and F, and the residual leukocytes Z values of all six blood collection and supply institutions were below 2, hinting at avenues for amelioration. 【Conclusion】 The SPC method anchored in binomial distribution exhibits substantial application merit in blood component quality management, facilitating real-time surveillance of blood collection, preparation, and storage procedures.
RESUMEN
Objective:To understand the current situation and influencing factors of depression among residents in Chongqing, and to explore the relationship between depression and administration satisfaction of the standardized residency training.Methods:Stratified random cluster sampling was used to select 372 residents currently participating the standardized residency training in Chongqing. The patient health questionnaire (PHQ-9) and administration satisfaction of residency training questionnaire were used to conduct a cross-sectional survey on the depression status and satisfaction of residents in Chongqing. SPSS 21.0 software package was used for partial correlation analysis and binary logistic regression analysis to explore the relationship between depression and administration satisfaction of the standardized residency training.Results:Among the 372 residents, 218 had mild depression and above (58.60%). There was a significant difference in the incidence of depression among residents of different ages, educational background, marital status, working hours and administration satisfaction of residency training ( χ2 = 23.02, 17.35, 12.24, 21.70, 95.20; P = 0.028, 0.027, 0.016, 0.041, <0.001 respectively). Partial correlation analysis showed that there was a negative correlation between the total score of depression and the five aspects of the administration satisfaction (total score, instructors, training base, managers and training income) ( r=-0.52, -0.45, -0.47, -0.45, -0.40, all P<0.01). In the binary logistic regression analysis of depression and satisfaction,the satisfaction had a negative impact on depression, and its B value was -1.71, and OR value was 0.18, P<0.001. Conclusion:The incidence of depression among residents in Chongqing is high. Age, educational background, marital status, working hours and administration satisfaction are related to the degree of depression. And the higher the degree of depression, the lower the administration satisfaction of residents. Relevant departments should pay attention to the mental health of residents and improve the quality of standardized residency training.
RESUMEN
【Objective】 To investigate the current situation concerning volume control of red blood cells in additive solution produced by blood service in Chongqing, and to lay a foundation for promoting the homogenization of preparation process of red blood cells in additive solution. 【Methods】 A questionnaire was designed to investigate the factors related to the preparation of red blood cells in additive solution. The questionnaire was sent by Chongqing Association of Blood Transfusion via E-mail to 18 blood services in the city, and the collected data was sorted, revised and analyzed by research team. 【Results】 A total of 18 blood services(including 1 blood center + 1 sub-center, 6 central blood stations and 11 central blood banks) returned the questionnaires. The results showed that there were differences among blood services across Chongqing, regarding the centrifugal parameters during preparation, the operation mode and monitoring situation of the capacity control during preparation, and the formulation of the capacity standard of red blood cells in additive solution etc. 【Conclusion】 The preparation process of red blood cells in additive solution, produced by Chongqing blood services, should be further standardized, and the capacity control method of this product in Chongqing should be gradually unified to achieve regional homogeneity and to ensure blood safety.
RESUMEN
Objective To investigate the cognition and attitude of check-up system in Standardized Residents Training Program in Chongqing, so as to provide further suggestions to improve teachers' qualifi-cation and examination management system. Methods From September 2016 to December, a questionnaire survey was conducted among 265 teachers and 59 teachers in Chongqing, which includes basic information of teachers and their cognition, satisfaction and suggestion of residents training examination management system. SPSS 21.0 was used to describe the survey results and the Spearman rank correlation analysis was conducted. Results 265 valid questionnaires were recovered, and the effective recovery rate was 100%. The survey showed that the teachers' cognition of resident training examination management system is good. Only 21 people (8%) completely had no knowledge of the management system of resident related assessment. A total of 90.6% of the clinical mentors considered that a check-up system of clinical mentors on training should be implemented strictly during the period of clinical mentors on training. Only 167 (63%) of the hos-pitals had developed detailed assessment system for resident physicians. Conclusion Most of the teachers in Chongqing have a higher awareness of living and training management system, and it is universally recog-nized for strict process assessment. However, in terms of the standardized training examination system for residency, it needs improvement. It is suggested that the examination system should be perfected, the ex-amination management be strengthened, and the teachers' team be standardized.
