The goal of this paper is to analyze a two unit parallel system subject to random shocks. For this purpose, a reliability model is developed in which two identical units work in parallel. The operative unit is subjected to random shocks with some probabilities. The unit fails completely through normal mode. The maintenance and repair of the unit are conducted by a server who visits the system i...

A parallel system of two identical units has been analyzed stochastically considering two types of servers. Initially, the unit is repaired by the ordinary sever who visits the system immediately. And, when ordinary server is unable to do repair of that unit in a given maximum repair time, the unit undergoes for inspection to see the feasibility of its repair by an expert server. If inspection ...

Use of unrelated donor cord blood (CB) as an alternative stem cell source is increasing, and yet there is little information to guide transplant centers in the unique aspects of the search and selection of CB grafts. There is no mechanism to easily access the global inventory of CB units, nor is the product information provided by all banks standardized. To address these challenges, this manusc...

Inappropriate initial antibiotics for pneumonia infection are usually linked to extended intensive care unit stay and are associated with an increased risk of mortality. This study evaluates the impact of inappropriate initial antibiotics on the length of intensive care unit stay, risk of mortality and the co-predictors that influences these outcomes. This retrospective study was conducted in a...

BACKGROUND Previous studies have demonstrated that organized, multidisciplinary care is the cornerstone of current strategies to reduce the death and disability caused by stroke. Identification of stroke units and an understanding of their composition and operation would provide insight for the further actions required to improve stroke care. The objective of this study was to identify and surv...

BACKGROUND Investigation of factors associated with variation in dialysis patient employment has focused primarily on patient-level factors. Little is known about facility-level factors that may be associated with patient employment. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS The ESRD Facility Survey (CMS-2744A) began in 2004 to collect counts of employed patients aged 18 to 54, in addit...

OBJECTIVES Limitations in the quality and access of cost data from low-income and middle-income countries constrain the implementation of economic evaluations. With the increasing prevalence of coronary artery disease in Malaysia, cost information is vital for cardiac service expansion. We aim to calculate the hospitalisation cost of percutaneous coronary intervention (PCI), using a data collec...
