Critical thinking for outcomes-based practice.

Abstract

Critical thinking is a vital component in managing patient-related outcomes at the staff level. It involves making observations and then asking "why?" Critical thinkers explore connections between current events and other events, stretching the boundaries of the situation. This allows the critical thinker to make new associations, challenge the status quo, find subtle patterns, and arrive at new formulations to old issues. Although nurses are most often traditional thinkers, it is possible to develop or refine their critical thinking skills through participation in learning situations that focus on exploring new approaches to thinking.

The influence of viewing conditions on radiological diagnosis of periapical inflammation.

OBJECTIVES: To determine the effect of viewing conditions upon diagnosis of early periapical inflammatory pathosis on intra-oral radiographs, and to examine the effect of observer experience upon diagnostic performance in this task. METHODS: 50 observers examined 18 periapical radiographs using three different viewing conditions (room lighting; viewing box; viewing box with x2 magnification and masking). Their diagnoses were compared with an 'expert' diagnosis provided by repeated viewings of the films by two dental radiologists. Sensitivities and specificities were determined. RESULTS: When 'ideal' viewing conditions were used, optimal sensitivity (78%) and specificity (78%) were obtained. Use of a viewing box was associated with significantly higher specificity than the use of room lighting (P = 0.0016). Use of masking and x2 magnification was associated with significantly higher sensitivity than a viewing box alone (P = 0.004). There were few significant differences in diagnostic performance between observers, but qualified dental staff had significantly higher specificities than 4th year (P = 0.01) and 5th year (P = 0.01) students when a viewing box was used alone. CONCLUSIONS: This study on early periapical inflammatory pathosis gives support to guidelines which recommend the use of a viewing box, x2 magnification and masking for interpreting intra-oral radiographs. It also suggests that observer experience may influence interpretation of early periapical pathosis.
