Impact of different discharge patterns on bed occupancy rate and bed waiting time: a simulation approach

Beds are one of the most important resources in a healthcare system. How to manage beds efficiently is an important indicator of the efficiency of the healthcare system. Bed management is challenging to many healthcare service providers in many aspects. In recent years, population growth and aging society impose extra pressure on bed requirement. There are usually two key performance indicators of a bed management system: bed occupancy rate and bed waiting time. In this paper, different discharge patterns and their impacts on the bed occupancy rate and bed waiting time are studied. A discrete event simulation model is constructed to evaluate the existing discharge pattern in a Singapore regional hospital using actual hospital admission and discharge transaction data. Then different discharge patterns are tested in the same context. Simulation results show that a proper discharge pattern significantly smoothes the fluctuation of bed occupancy rate and reduce the bed waiting time.     

乳头凹陷矫形方法临床500例研究

目的促进和支持母乳喂养,促进母婴健康。方法是将我院2009年1月—2013年12月就诊孕妇3000例中有乳头凹陷的500例进行乳头矫形。结果 500例行徒手手法矫形,成功300例,成功率60%,为徒手矫形组。剩余200例用20 mL空注射器去掉乳头磨平扣在乳头上,利用负压抽吸方法帮助乳头外突,成功200例,成功率100%,为负压抽吸组,负压抽吸法成功率要明显优于徒手手法矫形,差异明显,具有统计学意义。结论采用20 mL空注射器去掉乳头磨平扣在乳头上,利用负压抽吸方法帮助乳头外突,成功率高,孕妇痛苦少,方便,孕妇自己也可以操作,经济,实惠。深受孕妇及家人的信赖,值得临床大力推广。
