Screening for depression in chronic hemodialysis patients: comparison of the Beck Depression Inventory, primary nurse, and nephrology team

Depression in patients with end-state renal disease (ESRD) is both underdiagnosed and treated, which may contribute to an increase in morbidity and mortality. Efforts aimed at screening, diagnosing, and treating depression could potentially modify outcomes in this population. The purpose of this study was to compare the prevalence of depression, as measured by the Beck Depression Inventory (BDI-II), the primary nurse, and nephrology team, among a cohort of patients receiving chronic hemodialysis (HD). A secondary objective was to identify patient variables associated with depression. Patients were screened for depression at the same time point, using the BDI-II, the primary nurse and the nephrology team. Depression was defined as a BDI-II score > or =14. Agreement between the BDI-II score, nurse, and nephrology team assessment of depression was compared using a kappa score and receiver-operating characteristic (ROC) curves were generated. One hundred and twenty-four of an eligible 154 patients completed the study. Depression as measured by a BDI-II> or =14, the nurse and the team was diagnosed in 38.7%, 41.9%, and 24.2% of patients, respectively. With the BDI-II as the gold standard, the nurses' diagnosis of depression had an agreement of 74.6% vs. only 24.2% agreement with the nephrology team. A previous history of malignancy was the only variable associated with the diagnosis of depression. Depression is common among patients on HD, supporting the need for a routine depression-screening program. The primary dialysis nurse is in a key position to identify patients with depression and should be considered as an integral part of the nephrology team.     

中小民营企业供应链中的库存管理策略

供应链管理环境下的库存管理模式一般分为传统库存管理模式、JMI、VMI、CPFR四种。然而这四种模式如果在中小民营企业进行运用,都有着各自的缺陷和不足。本文提出第三方库存管理(TPMI,Third Party Managed Inventory)模式,并阐述了其在中小民营企业中的应用优势、问题及其对策,以供借鉴。

考虑中间库存缓冲区的设备不完美预防维修策略研究

针对带有库存缓冲区的设备维修问题,提出了随机故障设备的不完美预防维修策略。首先,考虑设备随机故障率随故障次数的增多而变大的情况,基于准更新过程,建立随机故障设备的故障次数表达式。其次,结合设备故障次数表达式,综合考虑维修成本和库存缓冲成本的基础上,构建了设备生产成本模型,以缓冲库存量和预防维修周期为自变量,以生产成本为目标函数。获得设备的最优维修策略和最佳库存缓冲量。最后,通过算例分析验证了模型的有效性,为生产线设计的可行性提供了依据。
