六西格玛在肿瘤标志物质量目标选择上的应用

目的应用6σ理论对肿瘤标志物项目的分析性能进行评价，并初步确定各项目的质量目标。 方法收集本实验室2018年1至12月室内质控数据和国家卫生健康委临床检验中心室间质量评价结果，以生物学变异导出的质量规范和国家室间质量评价标准作为允许总误差(TEa)计算6项肿瘤标志物的σ水平，并依据质量目标选择流程图和肿瘤标志物分析性能验证图评价肿瘤标志物的分析性能，进而为肿瘤标志物选择合适的质量目标。 结果应用不同层级的生物学变异导出的质量规范和国家室间质量评价标准，肿瘤标志物项目的σ水平存在显著差异；依据质量目标选择流程图：选择生物学变异导出的"适当的"质量规范作为CA125项目的质量目标，选择生物学变异导出的"最低的"质量规范作为t-PSA、CEA、AFP、CA199和CA153项目的质量目标。 结论6σ能够客观评价肿瘤标志物的分析性能，并为实验室质量目标的选择提供重要的参考价值。

Atención prehospitalaria urgente de los pacientes pediátricos expuestos a tóxicos: características epidemiológico-clínicas y evaluación de la calidad asistencial

ObjectiveTo describe the characteristics of paediatric patients with suspected poisoning treated by advanced life support (ALS) units, and to evaluate quality indicators (QI) for the prehospital emergency care of these patients.MethodA one-year observational study of patients under 18 years of age exposed to poisoning and treated by an ALS unit of the Medical Emergency System in Catalonia. Severe clinical criteria were defined, with 8 QI being evaluated for prehospital emergency care of poisoned paediatric patients.ResultsThe study included a total of 254 patients, with a median age of 14 years-old (p25-75 = 7-16), with intentional poisoning in 50.8% of cases. The most frequently involved toxic agent was carbon monoxide (CO) (33.8%). Poisoning was found in 48.8% of those patients, being serious in 16.5%. Intentionally (OR 5.1; 95% CI: 1.9-13.8) and knowledge of the time of exposure (OD 3.1; 95% CI: 1.3-7.3) were independent risk factors associated with the appearance of severe clinical symptoms. Five QI did not reach the quality standard and included, availability of specific clinical guidelines, activated charcoal administration in selected patients, oxygen therapy administration at maximum possible concentration in carbon monoxide poisoning, electrocardiographic assessment in patients exposed to cardiotoxic substances, and recording of the minimum data set.ConclusionsPaediatric patients attended by ALS units showed specific characteristics, highlighting the involvement of CO and adolescents with voluntary poisoning. The QI assessment was useful to detect weak points in the quality of care of these patients and to develop strategies for improvement.     

Trends in revisional bariatric surgery using the MBSAQIP database 2015-2017

BackgroundThe third most common bariatric surgery is revisional bariatric surgery. The American College of Surgeons tracks outcomes using the Metabolic and Bariatric Surgery Accreditation Quality Initiative Program database. We used this database to examine trends in revisional bariatric surgery.ObjectiveTo evaluate how trends in bariatric revisional surgery have changed in recent years.SettingUniversity Hospital, United States.MethodsThe Metabolic and Bariatric Surgery Accreditation Quality Initiative Program database for 2015 to 2017 was examined for revisions of bariatric surgery. Patients who underwent revisional bariatric surgery were identified by the primary Current Procedural Terminology code, the REVCONV and PREVIOUS_SURGERY field as well as secondary Current Procedural Terminology codes. There is no exact code for sleeve gastrectomy (SG) to laparoscopic Roux-en-Y gastric bypass (LRYGB), so we used 43644 (GB)+REVCONV+PREVIOUS_SURGERY for this.ResultsFor the years 2015 to 2017 there were 57,683 revisions/conversions of 528,081 patients. The number of revisions increased over the study period by 5213 cases. The most common revision was laparoscopic adjustable gastric band (LAGB) to SG with 15,433 cases and the second was LAGB to LRYGB with 10,485 cases. There were 14,715 LAGB removals. It is more difficult to track SG to LRYGB but there were 8491 unlisted cases, which may have been sleeve to bypass.ConclusionLAGBs are being taken out or converted, and this group makes up the largest portion of revisions and conversions. It is difficult to track SG to LRYGB, but the number of unlisted cases continues to climb. This will likely surpass LAGB conversions with time. The Metabolic and Bariatric Surgery Accreditation Quality Initiative Program should be modified to capture revisions/conversions of SG.     

养阴益气活血汤对慢性心力衰竭患者心功能及生活质量的影响

持续质量改进在体检科护理质量管理中的应用效果探讨

目的探究持续质量改进在体检科护理质量管理中的应用效果。方法该次将该院在2018年7-12月的体检者200名作为研究的对象,视为对照阶段,采取常规护理管理方法;将该院2019年1-6月的体检者200名作为观察阶段对象,在护理管理工作中采取持续质量改进管理模式,进一步对比两个阶段患者对于体检科工作质量的评分。结果在体检工作质量、服务态度、体检满意度这3个模块,观察阶段评分对照阶段比较均明显更高,差异有统计学意义(P<0.05)。结论持续质量改进应用于体检科护理质量管理中,可有效提升体检服务品质,值得推广应用。     

ArcCHECK系统在食管癌螺旋断层放疗计划验证中的应用

目的 探讨ArcCHECK系统在食管癌断层治疗旋转照射和固定野照射计划验证中的应用,总结相关经验。方法 对32例不同部位食管癌分别制作Helical旋转照射和Direct固定野照射验证计划,并通过ArcCHECK测量、分析,对比验证结果通过率。分析靶体积与计划验证通过率的相关性。将靶体积较小的治疗验证计划分别放在ArcCHECK模体中心和外周探测点处,分析验证通过率差异。结果 Helical计划验证通过率高于Direct计划(P<0.01),其靶体积与验证通过率的相关系数分别为-0.364和-0.042,P值分别为0.041和0.819。Helical计划采用3%/2mm标准时,高剂量区放在模体中心和外周探测点处测得的通过率不同(P=0.005),后者通过率更高;采用3%/3mm标准时与Direct计划的3%/3m、3%/2mm标准的相近(P均>0.05)。结论 Helical计划验证通过率普遍高于Direct计划,原因可能与ArcCHECK探测器的角度响应以及因更多参考点受到低剂量辐射而未参与计算有关,另外还可能跟Direct计划对断层治疗剂量控制系统要求更高有关。在Helical验证计划中,当采用3%/3mm标准时,靶体积越大,验证时出现较低通过率的可能性增加,但相关系数较低。验证计划的高剂量区位于模体中心或者探测点处都可以实现计划验证,综合考量建议放在模体等中心处。
