We report an extremely unique and previously unreported case of a pseudoaneurysm arising from an intercostal artery that also gave origin to the artery of Adamkiewicz. Due to the potential risk of losing the artery of Adamkiewicz, a conservative approach was indicated. On short interval follow-up imaging, the pseudoaneurysm and associated hematoma spontaneously resolved with preservation of the intercostal artery. We performed a literature review of the natural course of pseudoaneurysm as well as their occurrence in the intercostal arteries. [ABSTRACT FROM AUTHOR]

The traditional separation of the producers of research evidence in academia from the users of that evidence in healthcare organisations has not succeeded in closing the gap between what is known about the organisation and delivery of health services and what is actually done in practice. As a consequence, there is growing interest in alternative models of knowledge creation and mobilisation, ones which emphasise collaboration, active participation of all stakeholders, and a commitment to shared learning. Such models have robust historical, philosophical and methodological foundations but have not yet been embraced by many of the people working in the health sector. This paper presents an emerging model of participation, the Researcher-in-Residence. The model positions the researcher as a core member of a delivery team, actively negotiating a body of expertise which is different from, but complementary to, the expertise of managers and clinicians. Three examples of in-residence models are presented: an anthropologist working as a member of an executive team, operational researchers working in a front-line delivery team, and a Health Services Researcher working across an integrated care organisation. Each of these examples illustrates the contribution that an embedded researcher can make to a service-based team. They also highlight a number of unanswered questions about the model, including the required level of experience of the researcher and their areas of expertise, the institutional facilitators and barriers to embedding the model, and the risk that the independence of an embedded researcher might be compromised. The Researcher-in-Residence model has the potential to engage both academics and practitioners in the promotion of evidence-informed service improvement, but further evaluation is required before the model should be routinely used in practice.

Decisions about how to organize and deliver health services are often more complex and seemingly less rational than decisions about what clinical care to provide. The concept of ‘Evidence-Based Management’, or what might more appropriately be termed ‘Evidence-Informed Improvement’, does not seem to have captured the hearts and minds of the people responsible for managing health-care provision. Organizational decision-making is more likely to be influenced by political, ideological and pragmatic factors, and by the personal experience of the decision-makers, than by science. Whilst some people would regard the messiness of management decision-making as inevitable, most would accept that decisions could be improved by making greater use of the established health service research evidence, and through a stronger commitment to developing new evidence. Over the last two or more decades the evidence base created by Health Service Researchers has grown in quantity and in quality and yet much of it remains invisible to the people who most need to use it. This paper explores how the disconnect between the traditional ‘producers’ of research evidence in academia, and the managerial and clinical ‘consumers’ of that evidence, has contributed to the challenge of embedding an evidence-informed approach to service improvement. The advantages of a closer working relationship between academia and health services are outlined and three approaches to evidence creation and utilization are described which attempt to maximize the influence of scientific evidence on managerial practice.
