Excellence through evidence: structures enabling clinical autonomy.

Autonomy is a multidimensional process. Clinical autonomy, the dimension in which patients are the primary beneficiaries, is the focus of this study. Despite high valuation and persistent challenges to nurses to function autonomously, the relationship between autonomous practice and patient outcomes has not been empirically established due, in large measure, to a lack of correspondence between concepts and measurement of autonomy and to a lack of knowledge of enabling structures. The purpose of the research reported here is to identify the structures, practices, elements in the environment, and interventions that nurses, nurse managers, and physicians identify as promoting staff nurse clinical autonomy. Implementation of these interventions would then enable clinical decision making at the frontline and would foster studies to determine whether the expected linkage between clinical autonomy and positive patient outcomes prevails.

Accuracy, efficiency and preferences of survivors of traumatic brain injury when using three organization strategies to retrieve words.

The primary objective was to compare the accuracy and preferences of adult survivors of traumatic brain injury (TBI) when using three organization strategies--semantic topic, geographic place and a word's first letter (alphabet)--to retrieve words using augmentative and alternative communication (AAC) technology. A repeated measures research design was employed. Twelve adult survivors of TBI ranging in age from 18-50 years participated in the study. These participants retrieved words using an AAC system organized using the three experimental conditions. In addition, they rank-ordered their preferences for each of the three strategies. Results showed that adults with TBI retrieve words more accurately and more efficiently when using the alphabet organization strategy than when using the topic or place strategies. Despite this, participants expressed a preference for using the topic strategy. Explanations for the findings and implications for AAC use are provided.

Identifying Opportunities for Vertical Integration of Biochemistry and Clinical Medicine.

Objectives: Retention of basic science knowledge, as judged by National Board of Medical Examiners' (NBME) data, suffers due to lack of apparent relevance and isolation of instruction from clinical application, especially in biochemistry. However, the literature reveals no systematic process for identifying key biochemical concepts and associated clinical conditions. This study systematically identified difficult biochemical concepts and their common clinical conditions as a critical step towards enhancing relevance and retention of biochemistry.Methods: A multi-step/ multiple stakeholder process was used to: (1) identify important biochemistry concepts; (2) determine students' perceptions of concept difficulty; (3) assess biochemistry faculty, student, and clinical teaching scholars' perceived relevance of identified concepts; and (4) identify associated common clinical conditions for relevant and difficult concepts. Surveys and a modified Delphi process were used to gather data, subsequently analyzed using SPSS for Windows.Results: Sixteen key biochemical concepts were identified. Second year medical students rated 14/16 concepts as extremely difficult while fourth year students rated nine concepts as moderately to extremely difficult. On average, each teaching scholar generated common clinical conditions for 6.2 of the 16 concepts, yielding a set of seven critical concepts and associated clinical conditions.Conclusions: Key stakeholders in the instructional process struggle to identify biochemistry concepts that are critical, difficult to learn and associated with common clinical conditions. However, through a systematic process beginning with identification of concepts and associated clinical conditions, relevance of basic science instruction can be enhanced.
