In this exploratory study, nursing inferences were examined within a framework of information processing theory. Verbal responses to a patient simulation by 28 nursing students and 15 practicing nurses were used as data. Six different categories of inferences were identified. Inferences most frequently activated across educational levels were those about immediate situational concerns. Practicing nurses activated significantly more complex inferences than the student groups. In each group, the majority of inferences were activated during the first half of the encounter. These results of this preliminary analysis support the proposition that inference activation is an important component of the diagnostic reasoning process used by both nurses and nursing students. 相似文献

A visualization tool that integrates numeric information from an arterial blood gas report with novel graphics was designed for the purpose of promoting rapid and accurate interpretation of acid-base data. A study compared data interpretation performance when arterial blood gas results were presented in a traditional numerical list versus the graphical visualization tool. Critical-care nurses (n = 15) and nursing students (n = 15) were significantly more accurate identifying acid-base states and assessing trends in acid-base data when using the graphical visualization tool. Critical-care nurses and nursing students using traditional numerical data had an average accuracy of 69% and 74%, respectively. Using the visualization tool, average accuracy improved to 83% for critical-care nurses and 93% for nursing students. Analysis of response times demonstrated that the visualization tool might help nurses overcome the "speed/accuracy trade-off" during high-stress situations when rapid decisions must be rendered. Perceived mental workload was significantly reduced for nursing students when they used the graphical visualization tool. In this study, the effects of implementing the graphical visualization were greater for nursing students than for critical-care nurses, which may indicate that the experienced nurses needed more training and use of the new technology prior to testing to show similar gains. Results of the objective and subjective evaluations support the integration of this graphical visualization tool into clinical environments that require accurate and timely interpretation of arterial blood gas data. 相似文献

BACKGROUND: Italian Nursing Faculties use a range of tutorial strategies (laboratory sessions, intensive clinical tutoring, weekly tutoring) aimed to enhance nursing students' diagnostic reasoning: these strategies have different impacts on promoting student critical thinking. By using critical thinking methods, students develop abilities to check, monitor and constantly evaluate the accuracy of the diagnostic reasoning process. However, there is little evidence to show how effective tutorial strategies are on the accuracy of diagnostic reasoning. There is also very little known about the complexity of tutorial strategies because these are made up of several components (e.g. tutor questioning abilities, the value of the setting, the impact of the environment, the expertise of the tutor and the impact of the Faculty's philosophy of learning), tutorial strategies cannot be standardised and depend on multiple factors which are difficult to control. OBJECTIVES: The objective was to establish a relationship between tutorial strategies orientated to enhance critical thinking and the accuracy of diagnostic reasoning (i.e. the number of correct answers given by students on simulated cases in two different nursing education contexts). It was hypothesised that students who had had one laboratory session using intensive tutorial strategies had less probability of making reasoning errors in diagnosing a simulated case than a control group that had weekly tutorials or routine tutoring. DESIGN: A double pragmatic experimental study was adopted involving two Italian Nursing Faculties at universities in Verona and Udine. PARTICIPANTS: A total of 144 students in the first year of their Nursing Science Degree course were involved; in Verona, two random groups of 41students were taken (an intervention group and a control group). Random selections of 39 students for the intervention group and 29 students for a control group were made from the second campus in Udine. Data analysis was conducted comparing student outcomes in the same faculty (intra-trial analysis) and between the two campuses involved (inter-trial analysis). RESULTS: The students doing laboratory sessions and intensive clinical tutorials demonstrated fewer errors compared to the control group [OR 3.75; IC 95% 1.77-7.88], although the students who receive routine tutoring, demonstrated higher risk of mistaking the problems of the patient [OR 0.22; IC 0.95% 0.07-0.65]. CONCLUSION: From intra- and inter-trial analysis of the results, it can be concluded within limits, that those students who had had intensive tutorial strategies aimed developing critical thinking abilities, formulated fewer wrong hypotheses in the first list they made when confronted with a new nursing case. Faculties should consider these outcomes and develop strategies including intensive tutorial strategies for improving the accuracy of nursing students' clinical reasoning. 相似文献

This quasi-experimental study tested the effectiveness of an educational model, Developing Nurses' Thinking (DNT), on nursing students' clinical reasoning to achieve patient safety. Teaching nursing students to develop effective thinking habits that promote positive patient outcomes and patient safety is a challenging endeavor. Positive patient outcomes and safety are achieved when nurses accurately interpret data and subsequently implement appropriate plans of care. This study's pretest-posttest design determined whether use of the DNT model during 2 weeks of clinical postconferences improved nursing students' (N = 83) diagnostic accuracy. The DNT model helps students to integrate four constructs-patient safety, domain knowledge, critical thinking processes, and repeated practice-to guide their thinking when interpreting patient data and developing effective plans of care. The posttest scores of students from the intervention group showed statistically significant improvement in accuracy. 相似文献

PURPOSE. To compare the use of mental representations (heuristics) in diagnostic reasoning of expert (≥5 years' experience) and novice (<5 years' experience) emergency nurses.
METHODS. Clinical simulations were completed by a nationwide randomly selected sample of 173 experienced and 46 less-experienced emergency nurses ( N = 229).
FINDINGS. Experienced nurses used the heuristic, Judging by Causal Systems (diagnostic inferences deduced from systems of causal factors) significantly more did than less-experienced nurses.
PRACTICE IMPLICATIONS. Standardized nursing diagnoses may cut short the time needed to develop representational thinking and spare cognitive reserves for reasoning needed for complex patients. Faculty need to promote students' cognitive development through strategies that promote active, reflective, and integrative learning.

This paper reports on a study investigating the relationship of nursing students' approaches to learning and processing of information, science content knowledge, ability in interpreting and organizing clinical data (nursing assessment), and logical reasoning ability with the accuracy and quality of the nursing diagnosis made in a simulated diagnostic reasoning task. One hundred and sixty-nine second-year pre-service nursing students participated in the study. Results of path analyses indicated a set of pathways from surface approach to low-quality nursing diagnosis that reflected less competent diagnostic reasoning; and a second set from deep/achieving approach through content knowledge and logical reasoning to higher-quality nursing diagnosis that reflected more competent diagnostic reasoning. The implications of these findings for nurse education are discussed. 相似文献

PURPOSE: To examine the data collecting and interpreting phases of the diagnostic reasoning process used by practicing pediatric nurses and to determine: (a) types of information deemed important for planning nursing care; (b) the functional health patterns addressed; and (c) frequency of validation of early hypotheses. METHOD: Thirty-four registered nurses who attended continuing education pediatric nursing workshops were asked to analyze a written simulated case study discussing maternal-infant interaction. Diagnostic cues in the case study were based on a framework that consisted of a clinical nursing model of maternal-infant interaction and selected nursing diagnoses. Open-ended questions were used to examine subjects' attention to and interpretation of these cues. FINDINGS: All subjects identified information related to the child's physical needs and the mother's responsibility to meet those needs as important for planning nursing care. There was less attention given to the interaction of mother and child. The most common response was identification of cues associated with five functional health patterns (29.4% of subjects). The functional health pattern, coping-stress tolerance, was addressed least often, although all nurses identified cues associated with role relationship. Only 38% of the subjects identified the need for validation of early hypotheses. CONCLUSION: The findings support the need for further research on the diagnostic reasoning of pediatric nurses. Recommendations include methods to enhance pediatric nurses' collection and interpretation of data specific to the pediatric clinical setting. 相似文献

This study described the relationships between academic class and student moral sensitivity and reasoning and between curriculum design components for ethics education and student moral sensitivity and reasoning. The data were collected from freshman (n = 506) and senior students (n = 440) in eight baccalaureate nursing programs in South Korea by survey; the survey consisted of the Korean Moral Sensitivity Questionnaire and the Korean Defining Issues Test. The results showed that moral sensitivity scores in patient-oriented care and conflict were higher in senior students than in freshman students. Furthermore, more hours of ethics content were associated with higher principled thinking scores of senior students. Nursing education in South Korea may have an impact on developing student moral sensitivity. Planned ethics content in nursing curricula is necessary to improve moral sensitivity and moral reasoning of students. 相似文献

Discussions in the nursing literature about the usefulness of Kohlberg's theory of moral reasoning for women and nurses, and assertions about the level of moral reasoning scores of nurses have been clouded by inaccuracies and misperceptions. In this article, theoretical and measurement issues related to moral reasoning are clarified and a critical review of the literature is provided about the moral reasoning of nursing students and nurses as measured by the Defining Issues Test (DIT). The review indicates the need for greater rigor in studies of moral reasoning among nurses and the need for accuracy in interpreting and reporting moral reasoning scores. The data show that the moral reasoning of nurses, like that of other groups, tends to increase with formal education. Nurses' scores are usually comparable to, and sometimes higher than, scores of their academic peers. 相似文献

Even though clinical reasoning is attributed with the expert practitioner, there is limited evidence to support methods of teaching and learning that are used to foster its development in nurses. In nursing, a considerable range of teaching and learning strategies are available that can be used to develop clinical reasoning skills. This includes the think aloud seminar. This process oriented method has been successfully used to develop reasoning skills in nursing students [Lee, J.E.M. and Ryan-Wenger, N. 1997. The "think aloud" seminar for teaching clinical reasoning: A case study of a child with pharyngitis. J. Pediatric Health Care 11(1), 105-110.] and is one that should be adopted by nurse educators as a core teaching and learning strategy when educating pre-registration student nurses. 相似文献

Care forms the basic core of nursing actions. Traditionally nurses have described the acts of administering to patients as care behaviors. Many nurses find it difficult to define these caring behaviors. It is important that nurses have insight into the specific behaviors that patients perceive to be most important. Several studies have examined and compared nurses' and patients' perceptions of effective care behaviors. The literature supports an incongruence of what nurses perceive and what patients perceive as effective. This study identifies and compares student nurses' and professional nurses' perceptions of effective caring behaviors. The Caring Assessment Report Evaluation Q-sort (CARE-Q) was used to obtain the data. The participants included senior baccalaureate nursing students (n = 30) at Thomas Jefferson University, College of Allied Health Sciences, and professional nurses (n = 30) with 1 or more years experience. The significance of the difference between the groups was tested using the Mann Whitney U test. Results indicate agreement between the students and the nurses in all categories except trusting relationship (p = .06). The ages within the groups varied from 21 to 47 years. The difference in ages between the nurses and the students is significant (p = .0002). Findings provide a better understanding of student nurse perceptions of caring behaviors and provide implications for further research for nurse educators. 相似文献

Background
This paper reports a study about the effect of knowledge sources, such as handbooks, an assessment format and a predefined record structure for diagnostic documentation, as well as the influence of knowledge, disposition toward critical thinking and reasoning skills, on the accuracy of nursing diagnoses. Knowledge sources can support nurses in deriving diagnoses. A nurse??s disposition toward critical thinking and reasoning skills is also thought to influence the accuracy of his or her nursing diagnoses.Method
A randomised factorial design was used in 2008?C2009 to determine the effect of knowledge sources. We used the following instruments to assess the influence of ready knowledge, disposition, and reasoning skills on the accuracy of diagnoses: (1) a knowledge inventory, (2) the California Critical Thinking Disposition Inventory, and (3) the Health Science Reasoning Test. Nurses (n?=?249) were randomly assigned to one of four factorial groups, and were instructed to derive diagnoses based on an assessment interview with a simulated patient/actor.Results
The use of a predefined record structure resulted in a significantly higher accuracy of nursing diagnoses. A regression analysis reveals that almost half of the variance in the accuracy of diagnoses is explained by the use of a predefined record structure, a nurse??s age and the reasoning skills of `deduction?? and `analysis??.Conclusions
Improving nurses?? dispositions toward critical thinking and reasoning skills, and the use of a predefined record structure, improves accuracy of nursing diagnoses. 相似文献15.

This study addresses the problems in evaluating nursing diagnostic artificial intelligence (AI) expert systems. Two separate experiments (N=49) were conducted using a computer expert system. The first experiment, the "white box" experiment (n=9), compared the diagnostic techniques applied by experienced RNs against the programmed techniques used by the expert system. The second experiment, the "black box" experiment (n= 40), compared diagnostic results of beginning nurses against the computer expert systems results. In some cases the computer outperformed the nurses and vice versa. The evaluation techniques, as applied in both experiments, enhance the ability of nurses to evaluate and select AI expert systems to be used in computer-assisted diagnosis of nursing problems. 相似文献

The purpose of the study was to explore the diagnostic reasoning process among nursing students with different learning environments. A case-study design was adopted. Twenty subjects were randomly drawn from the last year of a pre-registration nursing programme in two institutions, 10 from a university and 10 from a nursing school. They were asked to complete the Bigg's Study Process Questionnaire and identify the differential diagnosis for the three simulated scenarios. The results showed no significant difference in study approaches between the two groups. Two subjects from the university made an incorrect differential diagnosis, as did one from the nursing school. Subjects from the university showed a mix of horizontal (66.6%) and vertical reasoning patterns (33.4%), while those from the nursing school used horizontal (100%) reasoning patterns. The results indicated that all subjects from the nursing school adopted backward chaining strategies (horizontal) for decision-making, i.e. hypothesis-driven. About a third of the subjects from the university adopted forward chaining strategies (vertical), i.e. data-driven. The study did not show any particular advantages from either of the two learning environments in terms of study approach. However, it highlighted the variations in decision strategies among students in the university setting. 相似文献

There is general consensus that clinical reasoning involves 2 stages: a rapid stage where 1 or more diagnostic hypotheses are advanced and a slower stage where these hypotheses are tested or confirmed. The rapid hypothesis generation stage is considered inaccessible for analysis or observation. Consequently, recent research on clinical reasoning has focused specifically on improving the accuracy of the slower, hypothesis confirmation stage. Three perspectives have developed in this line of research, and each proposes different error reduction strategies for clinical reasoning. This paper considers these 3 perspectives and examines the underlying assumptions. Additionally, this paper reviews the evidence, or lack of, behind each class of error reduction strategies. The first perspective takes an epidemiological stance, appealing to the benefits of incorporating population data and evidence‐based medicine in every day clinical reasoning. The second builds on the heuristic and bias research programme, appealing to a special class of dual process reasoning models that theorizes a rapid error prone cognitive process for problem solving with a slower more logical cognitive process capable of correcting those errors. Finally, the third perspective borrows from an exemplar model of categorization that explicitly relates clinical knowledge and experience to diagnostic accuracy. 相似文献

Abstract A pilot project is described that was initiated to provide a comprehensive clinical experience for community health nursing (CHN) students despite local cutbacks in field nursing services. The project, entitled the Nursing Elementary Education Outreach Project (NEEOP), is used as a basis for discussion on the CHN role in community-focused health care reform. One-third of the CHN students in one school of nursing during one academic year ( n = 16) participated in the NEEOP. One salaried CHN faculty member assumed primary responsibility, and equipment funding was granted by a local corporation. Collaboration was established with the county's proactive school nurses' association. CHN students developed and conducted health education presentations in elementary schools, worked with school nurses, and participated in other community health activities. Three levels of evaluation were utilized: elementary students to nursing students, nursing students to nursing faculty, and school nurses to nursing faculty. The NEEOP was a success by all evaluation criteria, and plans are currently in progress to expand its focus. Innovative clinical placements such as the one described can promote student understanding of CHN practice with its broad-based emphasis on the promotion of healthier communities. 相似文献
