The purpose of the study was to test a theoretical model explaining nurse practitioner judgments about the amount of interaction and participatory decision-making between nurse practitioners and physicians. The specific aims of the study included: (1) to examine the influence of nurse practitioner perceptions of care complexity and expected benefit-cost ratio of physician involvement on interaction and participatory decision-making; (2) to test a theory that integrates two alternative explanations of amount of interaction and participatory decision-making derived from social exchange theory and technology theory; and (3) to investigate the effect of practice rules on the relationships in the theoretical model. The study used a mathematical correlational design with a causal modeling methodology for model testing. A convenience sample of 38 nurse practitioners participated. Major concepts in the model were measured using a four scale magnitude estimation instrument developed for the study. The instrument consisted of operational definitions for each of the concepts and a set of 18 clinical situations scaled according to care complexity. Psychometric properties of the instrument including stability, internal consistency, content and construct validity were estimated. Matching of responses across two modalities was used to validate the production of ratio level data. Multiple regression techniques were used for theoretical model testing. In the test of the theoretical model, both care complexity and expected benefit-cost ratio had a significant impact on the nurse practitioners' judgments about amount of interaction and participatory decision-making. Predictions derived from social exchange theory and technology theory were supported. The effect of practice rules on the relationships in the model could not be determined since the index of practice rules did not achieve an acceptable level of stability. Nurse practitioner judgments about interaction and participatory decision-making were influenced by perceptions of care complexity and expectations of the benefits and costs of interaction with a specific physician. An understanding of the factors that affect nurse practitioner judgments about interaction and participatory decision-making may be used to guide interventions that enhance the fit between these structures and outcomes of care.

Communication is a critical aspect of clinical work. In 2010, the Joint Commission (JC) found that gaps in communication were among leading factors contributing to medical errors. Healthcare processes, such as patient discharge, depend on interdisciplinary communication to be successful. Electronic health records (EHRs) have the potential to facilitate communication and information sharing between interdisciplinary care team members; however, challenges remain in designing tools for team-based care and questions remain in understanding how EHRs impact interdisciplinary team communication. This dissertation focuses on understanding how EHRs can be designed to support communication and information sharing within interdisciplinary patient care teams. The first aim of the dissertation investigated how EHRs impact interdisciplinary clinical teams’ communication, shared mental models, and information sharing activities. The results showed that implementing new EHR tools appeared to have little impact on communication and shared mental models, but new information sharing activities mediated by EHR developed. These changes and lack thereof suggest that new EHR tools will be specifically needed to facilitate interdisciplinary team information sharing activities. The second aim of the dissertation investigates the information sharing activities and information needs of interdisciplinary team members during patient discharge. The results showed that the information clinicians sought out during discharge depended on the roles that person played as well as the progress of the discharge process. Future EHR tools should be aware of how patient care teams are progressing through the patient discharge process in order to provide information contextualized to their current tasks. In conclusion, interdisciplinary team communication and information sharing remain poorly supported by current EHRs and new tools designed specifically for interdisciplinary teams should provide information based on the completion of team activities.

The traditional model of leadership in medicine and health care generally centres around a hierarchical structure of power and influence, resting in the hands of a select few administrators, with limited input from employees. A newly developed Cancer treatment centre in the Province of British Columbia, Canada has attempted to institute a unique, team-based system of shared leadership and decision-making. In order to accomplish this task, the Senior Administrator of the centre hired professional group development experts to facilitate the formation of the newly established Leadership Team. A team of nine individuals participated in a group-process based model of team leadership development, consisting of a series of intensive weekend workshops. This study evaluates the impact of those intensive workshops on the members of the Cancer centre Leadership Team. Qualitative case-study methodology, combined with the use of indepth interviews, illuminated eight categories of shared experience among seven of the nine team members, as a result of having participated in the workshop series.

"In the main, contemporary research on Evidence Based Practice (EBP) has taken place within metropolitan locations, and has offered urbocentric solutions and insights. However the transferability of these developments to rural services is untested empirically. In addition, evidence development and studies on the implementation of this evidence have tended to be discipline-stream-specific; there has been very little research into either the development of multi-disciplinary evidence guidelines or the implementation of EBP from the perspective of individual practitioners working within multi-disciplinary teams. This research shortfall has provided the rationale for this study...." / Doctor of Philosophy
