Factors Affecting the Failure of Patient Safety Target Indicators in the Regional Hospital of the Datu Beru Takengon Central Aceh

The application of patient safety management is very important in an effort to prevent or minimize the occurrence of adverse patient safety incidents. The purpose of this study was to identify the factors that influence the achievement of patient safety target indicators. The method is a quantitative observational study with a cross sectional study approach. The study population was a nurse who worked in the inpatient room with a sample of 60 people who were taken by purposive sampling. The statistical test used is Multiple Linear Regression Analysis. The results of the Multiple Linear Regression Test show that knowledge, communication systems, commitment and experience (regression coefficient values ​​of 0.164, 1.1192, 0.528 and 1.169 have a positive influence on the achievement of patient safety goal indicators and leadership, risk management systems and reporting systems have a significant influence. Negative impact on the achievement of patient safety target indicators (regression coefficient values ​​of -0.064, - 0.967 and -0.281). The results of the t test were obtained that the communication system is the dominant factor that has a significant effect on the achievement of the patient safety goal indicators. Significant towards the achievement of patient safety target indicators. It is expected that input or consideration for the hospital in evaluating and improving hospital policies in increasing the achievement of patient safety target indicators is in accordance with existing targets.

Some Exact Solutions of the Einstein-Maxwell Field Equations in Spherical Geometry

In this thesis, the aim is to present some new classes of non–static and static, spherically symmetric solutions of the Einstein–Maxwell field equations representing compact objects with negative pressure. Throughoutthisthesisthespace–timegeometryisspherical,theradial pressure is negative, and the matter density equals the negative value of the radial pressure (either it is considered or it comes out as a consequence of the calculations). Several non–static solutions are found by taking an ansatz for the components of the metric tensor and on thesquareofelectricfieldintensity. Thesolutionsareshowntosatisfy physical boundary conditions associated with the exact solutions of the Einstein–Maxwell field equations. Due to negative pressure, these solutions can model physical systems such as expanding compact objects containing negative pressure. Petrov and Segr´e classifications that these obtained solutions admit are also discussed in detail. Two staticsolutionsofthefieldequationsarealsoobtainedwiththeansatz similar to that for the non–static cases in order to have a look how the solutions behave for these kind of ansatz in static geometry.
