Applying Knowledge Translation in Rehabilitation: An Exploration of What it Means to Change Clinical Practice

Health care providers are often required to implement evidence-based recommendations into the care they deliver. Resources that support health care providers’ efforts are a useful knowledge translation strategy. This thesis describes the development and usability evaluation of an evidence-informed clinical practice implementation toolkit to support implementation efforts. Two studies were undertaken to provide insight into what was needed to support health care providers, and to inform the development of the toolkit. A retrospective evaluation analyzed the performance of a team implementing a pressure ulcer risk assessment for patients with spinal cord injury. The rates of adherence to the risk assessment and action plan were low at both admission and reassessment. A phenomenology of practice study was conducted to understand the experiences of implementation by health care providers. This study identified five essential themes of the experience: decision making, implementation as a process, lived time, lived human relation, and lived space. The principles of integrated knowledge translation, the Knowledge Exchange Framework, and toolkit development resources were used in this study. This toolkit contains a simplified, phased implementation process based on the Active Implementation Frameworks, and is accompanied by tools. The toolkit received very positive usability ratings: 92% of respondents learned something new from reviewing the toolkit; 100% of respondents said the toolkit was well organized; 92% of respondents said the toolkit was easy to use; 92% of respondents would recommend the toolkit to a colleague; and 92% of respondents showed intention to use the toolkit. This body of work contributes to the fields of knowledge translation and implementation science by generating insight into and appreciation of the process, context, and stakeholders in relation to implementing evidence-based guidelines into routine care delivery practices

In search of the authentic nation: landscape and national identity in Canada and Switzerland

While the study of nationalism and national identity has flourished in the last decade, little attention has been devoted to the conditions under which natural environments acquire significance in definitions of nationhood. This article examines the identity-forming role of landscape depictions in two polyethnic nation-states: Canada and Switzerland. Two types of geographical national identity are identified. The first – what we call the ‘nationalisation of nature’– portrays zarticular landscapes as expressions of national authenticity. The second pattern – what we refer to as the ‘naturalisation of the nation’– rests upon a notion of geographical determinism that depicts specific landscapes as forces capable of determining national identity. The authors offer two reasons why the second pattern came to prevail in the cases under consideration: (1) the affinity between wild landscape and the Romantic ideal of pure, rugged nature, and (2) a divergence between the nationalist ideal of ethnic homogeneity and the polyethnic composition of the two societies under consideration

A comparison of the pharmacokinetics of Aspen Ceftriaxone and Rocephin in community-acquired meningitis

BACKGROUND. Community-acquired bacterial meningitis (CABM) is a life-threatening condition that is common among immunocompromised individuals. Intravenous ceftriaxone, of which Rocephin (ROC) is the originator brand, is recommended as first-line therapy in South Africa. Despite concerns regarding therapeutic equivalence with generic agents, this is the first study that has been conducted comparing clinical pharmacokinetics (PK) of a generic ceftriaxone formulation with the originator. OBJECTIVE. To compare the PK and safety of Aspen Ceftriaxone (AC) and ROC in the treatment of adult CABM. METHODS. A total of 63 eligible patients were randomised 1:1 to receive 2 g of either medication twice daily for a duration based on the identity of the causative organism and their physician’s clinical judgment. The primary endpoint of this study was the comparison of clinical PK, specifically the concentrations of each drug in the cerebrospinal fluid with corresponding paired plasma samples. While this study was underpowered to assess efficacy, safety could be evaluated on the basis of reported adverse events. RESULTS. The two patient groups were epidemiologically similar. There were no statistically significant differences in PK between either agent, nor any difference with regard to safety. CONCLUSION. AC can be considered as equivalent to ROC with regard to PK and safety in patients with CABM.Aspen Pharmacare Ltd, SA.http://www.samj.org.zaam2014ay201

Whole Slide Imaging Versus Microscopy for Primary Diagnosis in Surgical Pathology: A Multicenter Blinded Randomized Noninferiority Study of 1992 Cases (Pivotal Study)

Most prior studies of primary diagnosis in surgical pathology using whole slide imaging (WSI) versus microscopy have focused on specific organ systems or included relatively few cases. The objective of this study was to demonstrate that WSI is noninferior to microscopy for primary diagnosis in surgical pathology. A blinded randomized noninferiority study was conducted across the entire range of surgical pathology cases (biopsies and resections, including hematoxylin and eosin, immunohistochemistry, and special stains) from 4 institutions using the original sign-out diagnosis (baseline diagnosis) as the reference standard. Cases were scanned, converted to WSI and randomized. Sixteen pathologists interpreted cases by microscopy or WSI, followed by a wash-out period of ≥4 weeks, after which cases were read by the same observers using the other modality. Major discordances were identified by an adjudication panel, and the differences between major discordance rates for both microscopy (against the reference standard) and WSI (against the reference standard) were calculated. A total of 1992 cases were included, resulting in 15,925 reads. The major discordance rate with the reference standard diagnosis was 4.9% for WSI and 4.6% for microscopy. The difference between major discordance rates for microscopy and WSI was 0.4% (95% confidence interval, -0.30% to 1.01%). The difference in major discordance rates for WSI and microscopy was highest in endocrine pathology (1.8%), neoplastic kidney pathology (1.5%), urinary bladder pathology (1.3%), and gynecologic pathology (1.2%). Detailed analysis of these cases revealed no instances where interpretation by WSI was consistently inaccurate compared with microscopy for multiple observers. We conclude that WSI is noninferior to microscopy for primary diagnosis in surgical pathology, including biopsies and resections stained with hematoxylin and eosin, immunohistochemistry and special stains. This conclusion is valid across a wide variety of organ systems and specimen types

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure
