Konfliktmatrix: Instrument des Risikomanagements im Operationssaal

Hintergrund In der Wirtschaft sind Konflikte als Ursache von hohen Kosten und Leistungseinbußen lange bekannt. Bei der Prozessoptimierung im OP-Management findet dieser Aspekt noch keine Beachtung. Gerade im Bereich der Ablauforganisation im OP führen unklare Arbeitsteilungen und mangelnde Kommunikation oft dazu, dass sich die verschiedenen Berufsgruppen als „Konkurrenten“ im Umfeld der Patienten sehen, anstatt als „multiprofessionelles Team“ zu agieren. Dies führt unweigerlich zur Entstehung und zur Eskalation von Konflikten. Fragestellung Die von uns entwickelte Konfliktmatrix soll es ermöglichen, mit minimalem Aufwand das Ausmaß der Konflikteskalation im multiprofessionellen OP-Team objektivierbar zu erfassen. Material und Methoden Im Bereich eines OP-Bereiches mit 8 OP-Tischen werden alle leitenden Mitarbeitenden aufgefordert, die Konflikteskalation zwischen den einzelnen Berufsgruppen auf einer Skala vonBackground In business conflicts have long been known to have a negative effect on costs and team performance. In medicine this aspect has been widely neglected, especially when optimizing processes for operating room (OR) management. In the multidisciplinary setting of OR management, shortcomings in rules for decision making and lack of communication result in members perceiving themselves as competitors in the patients environment rather than acting as art of a multiprofessional team. This inevitably leads to the emergence and escalation of conflicts. Objective We developed a conflict matrix to provide an inexpensive and objective way for evaluating the level of escalation of conflicts in a multiprofessional working environment, such as an OR. Material and methods The senior members of all involved disciplines were asked to estimate the level of conflict escalation between the individual professional groups on a scale of 09. By aggregating the response data, an overview of the conflict matrix within this OR section was created. Results No feedback was received from 1 of the 11 contacted occupational groups. By color coding the median, minimum and maximum values of the retrieved data, an intuitive overview of the escalation levels of conflict could be provided. The value range of all feedbacks was between(VLID)354395

“Digging Deeper” into the Relationship Between Safety Climate and Turnover Intention Among Stone, Sand and Gravel Mine Workers: Job Satisfaction as a Mediator

Employee turnover has been linked to negative business performance outcomes, increased costs, and disruptions to operations. Research to explore predictors of turnover intention is important to the mining industry, including the stone, sand, and gravel mining (SSGM) industry. Safety climate has been linked to job satisfaction and reductions in turnover intention in other fields, but investigation within SSGM has virtually been non-existent, creating a knowledge gap. This research seeks to address this dearth of information. Cross-sectional data from 452 workers in the SSGM industry were analyzed to assess the influence of safety climate on turnover intention through job satisfaction. Mediation analyses showed that job satisfaction significantly mediated the relationship between safety climate and turnover intention. The implications of these novel findings are important for SSGM administrators. It suggests that bolstering safety programs and increasing safety climate perceptions will help increase job satisfaction and reduce turnover intention among workers in the SSGM industry

High Frequency Transducer Development for Ultrasonic Tests on Ceramic Components

The detection of critical flaws in ceramics requires the use of high frequency ultrasonics. Whilst shorter wavelengths are necessary to detect low micrometer range flaws, so the higher the frequency, the higher the attenuation and so ultimate power and sensitivity is required from examining transducers. This paper outlines the development of such devices. Satisfactory transducers in the frequency range 30–100 MHz are not available commercially and the characteristics of a number of piezoelectric materials for the purpose of their development are being established. Properties such as composition, electrodes, backing and lenses are being investigated

Disclosing physician ratings: performance effects and the difficulty of altering rating consensus

I examine effects of a health care system's policy to publicly disclose patient ratings of its physicians. I find evidence that this policy leads to performance improvement by the disclosed, subjective ratings and also by undisclosed, objective measures of quality. These effects are consistent with multitasking theory, in that physicians respond to the disclosure by providing more of a shared input—time with patients—that benefits performance by ratings and underlying quality. I also find, as predicted by information cascade theory, that the ratings become jammed to some degree near initially disclosed values. Specifically, raters observe the pattern of initial ratings and follow suit by providing similar ratings. Finally, I find evidence that physicians anticipate rating jamming and so concentrate their effort on earlier performance in order to set a pattern of high ratings that later ratings follow. These results demonstrate that the disclosure of subjective ratings can benefit performance broadly but can also shift effort toward earlier performance

The diverse nature of island isolation and its effect on land bridge insular faunas

Aim: Isolation is a key factor in island biology. It is usually defined as the distance to the geographically nearest mainland, but many other definitions exist. We explored how testing different isolation indices affects the inference of impacts of isolation on faunal characteristics. We focused on land bridge islands and compared the relationships of many spatial and temporal (i.e., through time) isolation indices with community‐, population‐ and individual‐level characteristics (species richness, population density and body size, respectively). Location: Aegean Sea islands, Greece. Time period: Current. Taxon: Many animal taxa. Methods: We estimated 21 isolation indices for 205 islands and recorded species richness data for 15 taxa (invertebrates and vertebrates). We obtained body size data for seven lizard species and population density data for three. We explored how well indices predict each characteristic, in each taxon, by conducting a series of ordinary least squares regressions (controlling for island area when needed) and a meta‐analysis. Results: Isolation was significantly (and negatively) associated with species richness in 10 of 15 taxa. It was significantly (and positively) associated with body size in only one of seven species and was not associated with population density. The effect of isolation on species richness was much weaker than that of island area, regardless of the index tested. Spatial indices generally out‐performed temporal indices, and indices directly related to the mainland out‐performed those related mainly to neighbouring islands. No index was universally superior to others, including the distance to the geographically nearest mainland. Main conclusions: The choice of index can alter our perception of the impacts of isolation on biological patterns. The nearly automatic, ubiquitous use of distance to the geographically nearest mainland misrepresents the complexity of the effects of isolation. We recommend the simultaneous testing of several indices that represent different aspects of isolation, in order to produce more constructive and thorough investigations and avoid imprecise inference
