Abstract
-
This was a quasi-experimental study, pretest and posttest design, to determine whether use of the Developing Nurses' Thinking (DNT) model during two weeks of clinical post conferences improved nursing students' diagnostic accuracy. The DNT model integrates four constructs, patient safety, domain knowledge, critical thinking processes, and repeated practice, to guide students' thinking when interpreting patient data and developing effective plans of care. Two accompanying worksheets helped students to operationalize the model and provided guidance for thinking processes. Students ( N = 83) from two baccalaureate degree programs in the first clinical nursing courses volunteered to participate in the study. Two sets of two parallel case studies were developed for the pretest and posttest and validated by three experienced faculty. Diagnostic accuracy was measured on a seven point scale using the Lunney Scoring Method. Statistical analyses included independent t - test, paired t - test, and general linear regression modeling. The results were that both groups of students varied widely in accuracy of nursing diagnosis. The hypothesis was supported in that the intervention group had statistically significant improvement in accuracy posttest scores compared to those in the control group. The results were consistent with previous studies that accuracy varied and use of a teaching aid such as the DNT model helped nursing students to improve accuracy. The implications are that use of a model that integrates the constructs of patient safety, domain knowledge, critical thinking process, and repeated practice, the DNT model, may help nursing students to develop effective thinking habits in the context of patient safety and improve diagnostic accuracy.
