Nurses Opinions Regarding Delirium Care in the Older General Hospital Population and in Older Cardiac Surgery Patients Specifically

Delirium is a serious disturbance in mental abilities that results in confused thinking and reduced awareness of the environment. The start of delirium is usually rapid — within hours or a few days. It is also a high prevalent postoperative complication in older cardiac surgery patients. An occurring delirium can have drastic long term consequences for the patient, like prolonged (months) functional (activity of daily live) dependency, an enormous fear because of occurring hallucinations, increased morbidity and mortality. Consequently, a delirium increases patient burden, healthcare demand and healthcare costs.

Preventive interventions, diagnosis and treatment of delirium require specialized knowledge and skills. Since nurses play a key role in hospital care, a successful implementation of nursing interventions for prevention, early and accurate diagnosis and treatment of delirium in older surgery patients is important. In this study, the authors aimed to gain insight in opinions and beliefs of nurses in hospitals concerning prevention, diagnosis and treatment of delirium in older hospital patients in general and specifically in older cardiac surgery patients.

In a cross-sectional study from February to July 2010, the authors distributed a survey on beliefs on delirium care among 368 nurses in three hospitals in the Netherlands, in one hospital in all wards with older patients and in two hospitals in the cardiac surgery wards only.

The results revealed that although in literature incidence rates up to 54.9% in cardiac surgery patients in hospitals were reported, with a response rate of 68% (250), half of the nurses believed that the incidence of delirium was not even 10%. Two thirds think that delirium in patients was preventable. Although, the Delirium Observation Scale was most often used for screening delirium, nearly all nurses did not routinely screen patients for delirium. Opinions on delirium of nurses working in cardiac surgery wards did not differ from nurses caring for older patients in other hospital wards.

In summary, although nurses in the hospitals do have knowledge on prevention, diagnosis and treatment of delirium, they underestimate the occurrence of delirium in patients. As a consequence, they do not screen patients on a routine basis. And because they do not screen patients on a routine basis they underestimate the incidence of delirium in older patients during their hospital admission.

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...

Location Optimization of a Coal Power Plant to Balance Costs against Plant’s Emission Exposure

Fuel and its delivery cost comprise the biggest expense in coal power plant operations. Delivery of electricity from generation to consumers requires investment in power lines and transmission grids. Placing a coal power plant or multiple power plants near dense population centers can lower transmission costs. If a coalmine is nearby, transportation costs can also be reduced. However, emissions from coal plants play a key role in worsening health crises in many countries. And coal upon combustion produces CO 2 , SO 2 , NO x , CO, Metallic and Particle Matter (PM10 & PM2.5). The presence of these chemical compounds in the atmosphere in close vicinity to humans, livestock, and agriculture carries detrimental health consequences. The goal of the research was to develop a methodology to minimize the public’s exposure to harmful emissions from coal power plants while maintaining minimal operational costs related to electric distribution losses and coal logistics. The objective was...

Effects of Karate Training on Basic Motor Abilities of Primary School Children

“You never attack first in karate” might be the best conclusion of karate, which is a martial art practiced typically without weapons. It’s reported that karate has a long history for several hundred years, but the modern karate was spread to the whole Japan from Okinawa in the early part of 20th century. Now it has become one of the most widely practiced martial art forms in the world. Usually, it’s divided into Kihon, Kata and Kumite. As for the beginners, Kihon is more suitable for them because it involves basic techniques. Due to karate consists of dynamic offensive and defensive techniques using all parts of the body to their maximum advantage, the best understanding of true karate practice is the perfection of oneself through the perfection of the art. It not only develops coordination, quickens reflexes, and builds stamina, but also develops composure, a clearer thought process, deeper insight into one’s mental capabilities, and more self-confidence. So many researchers stu...
