If we examine the underlying enablers for the significant gains that have been achieved, the key role that research to help understand the causes of problems and to develop lasting solutions is clear. Many of the remaining challenges have been resistant to solutions by various approaches. Some, such as fatalities and injuries from ground control or powered haulage are prominent year after year. Different approaches are indicated and new solutions will be required if we are to achieve a goal of zero harm. These will originate with research, but into which topics, and what are some of these different approaches? This paper examines the current state of mine safety in the United States and highlights areas of significant opportunity for research that will lead to solutions. The likely direction of research that will enable realization of the ‘‘zero harm'' goal is described in terms of evolutionary and revolutionary approaches. Both are important, but the author's view is that some of the largest gains will be made with trans-disciplinary approaches that break from the past. Topical areas of research are suggested and several research questions are given to illustrate the direction of future research in mining safety and health.展开更多

文摘Objective:This study aimed to describe the implementation of the surgical safety check policy and the surgical safety checklist for invasive procedures outside the operating room(OR)and evaluate its effectiveness.Methods:In 2017,to improve the safety of patients who underwent invasive procedures outside of the OR,the hospital quality and safety committee established the surgery safety check committee responsible for developing a new working plan,revise the surgery safety check policy,surgery safety check Keywords:Invasive procedures outside the operating room Safety management Surgical safety checklist Patient safety form,and provide training to the related staff,evaluated their competency,and implemented the updated surgical safety check policy and checklist.The study compared the data of pre-implementation(Apr to Sep 2017)and two post-implementation phases(Apr to Sep 2018,Apr to Sep 2019).It also evaluated the number of completed surgery safety checklist,correct signature,and correct timing of signature.Results:The results showed an increase in the completion rate of the safety checklist after the program implementation from 41.7%(521/1,249)to 90.4%(3,572/3,950),the correct rates of signature from 41.9%(218/521)to 99.0%(4,423/4,465),and the correct timing rates of signature from 34.4%(179/521)to 98.5%(4,401/4,465),with statistical significance(P<0.01).Conclusion:Implementing the updated surgery safety check significantly is a necessary and effective measure to ensure patient safety for those who underwent invasive procedures outside the OR.Implementing surgical safety checks roused up the clinical staff's compliance in performing safety checks,and enhanced team collaboration and communication.

文摘Aiming at the deficiency of exterminating measures of Chinese firm safety management, a simulation model of Chinese firm＇s safety management capability based on the organizational learning theory, in which the simulation method of system dynamics is utilized. The level variable and rate variable are designed based on the practical situation and change situation of corresponding variables of firm＇s safety management ca- pability. Simulation firms are built with accident case groups of the oil industry, chemical industry, machine industry, coal mining industry, and weapon industry. Through analyzing the simulation result, the growth law of Chinese firm＇s safety management capability is obtained as follows： the accumulating and the coupling of safety knowledge should be emphasized at the same time; the balance of learning behavior of individual, group and organization should be considered together; different types of Chinese firm should take different safety policies according to their practical situations.
