出院准备度评估在首发精神分裂症患中的应用

目的探讨出院准备度评估对首发精神分裂症患者出院后康复情况的影响。方法选取2016年10月-2017年3月在四川省精神卫生中心住院、符合《国际疾病分类(第10版)》(ICD-10)精神分裂症诊断标准的首发精神分裂症患者60例,采用随机数字表法分为研究组和对照组各30例。两组患者均接受奥氮平治疗4周及以上,对照组由医生评估后下达医嘱办理出院,研究组由医生评估后下达出院医嘱,并接受出院准备度量表(RDQ)评定,评估达到标准后再办理出院。对两组患者在出院后1月、6月、12月通过电话或门诊随访的方式进行回访,采用自制出院回访调查表了解患者出院后康复情况。结果出院后研究组与对照组复发且再次入院、出现情绪问题、生活不能自理、自行停药情况、睡眠异常5个方面差异均有统计学意义(P均0. 05)。出院后1月,研究组满意度高于对照组,差异有统计学意义(P0. 05)。结论对于首发精神分裂症患者,通过出院准备度评估,可能有助于判断患者出院后进一步康复的能力。

急性心肌梗死患者血清sLOX-1、CK-MB水平及意义

四肢烧伤患者行急诊负压封闭引流术的疗效观察

目的探究应用急诊切痂植皮配合负压封闭引流术治疗四肢烧伤的临床疗效。方法按随机抽取法将医院2018年2月—2019年1月间收治的57例四肢烧伤患者分为常规组和实验组,常规组28例,实验组29例。给予常规组患者急诊切痂植皮,用常规换药配合治疗,而实验组在常规组的基础上用负压封闭引流术配合治疗。比较常规组患者和实验组患者的临床效果、疼痛程度评分。结果两组患者的总有效率对比,实验组总有效率吗,明显高于常规组的总有效率,实验和常规组差异具有统计学意义(P<0.05)。常规组患者的疼痛评分高于实验组患者,差异具有统计学意义(P<0.05)。结论四肢烧伤患者通过应用急诊切痂植皮配合负压封闭引流术治疗后,临床效果得到有效改善,质量生活水平得到提高。     

Prognostic models for mortality after cardiac surgery in patients with infective endocarditis: a systematic review and aggregation of prediction models

BackgroundThere are several prognostic models to estimate the risk of mortality after surgery for active infective endocarditis (IE). However, these models incorporate different predictors and their performance is uncertain.ObjectiveWe systematically reviewed and critically appraised all available prediction models of postoperative mortality in patients undergoing surgery for IE, and aggregated them into a meta-model.Data sourcesWe searched Medline and EMBASE databases from inception to June 2020.Study eligibility criteriaWe included studies that developed or updated a prognostic model of postoperative mortality in patient with IE.MethodsWe assessed the risk of bias of the models using PROBAST (Prediction model Risk Of Bias ASsessment Tool) and we aggregated them into an aggregate meta-model based on stacked regressions and optimized it for a nationwide registry of IE patients. The meta-model performance was assessed using bootstrap validation methods and adjusted for optimism.ResultsWe identified 11 prognostic models for postoperative mortality. Eight models had a high risk of bias. The meta-model included weighted predictors from the remaining three models (EndoSCORE, specific ES-I and specific ES-II), which were not rated as high risk of bias and provided full model equations. Additionally, two variables (age and infectious agent) that had been modelled differently across studies, were estimated based on the nationwide registry. The performance of the meta-model was better than the original three models, with the corresponding performance measures: C-statistics 0.79 (95% CI 0.76–0.82), calibration slope 0.98 (95% CI 0.86–1.13) and calibration-in-the-large –0.05 (95% CI –0.20 to 0.11).ConclusionsThe meta-model outperformed published models and showed a robust predictive capacity for predicting the individualized risk of postoperative mortality in patients with IE.Protocol registrationPROSPERO (registration number CRD42020192602).
