RESUMEN

When patients are discharged from the hospital and return home, they are at risk of adverse events if the continuity of care is broken. So far, the evidence for transitional care models to reduce readmission rates has focused mainly on patients with a single condition. Based on this observation, we identified the population that may benefit the most from the development of a new transitional care model, as part of the INSTEAD project, by consensus between patients and professionals in hospitals and the community. To ensure continuity of care, it is necessary to consider the patients' perception, their understanding of the care plan and changes impacting the home care plan. Interprofessional collaboration is essential to achieve this.

Lorsqu'un-e patient-e retourne à domicile suite à une hospitalisation il-elle est souvent confronté-e à des événements indésirables si la continuité de ses soins n'est pas assurée. Jusqu'à ce jour, les modèles de soins de transition qui ont montré une diminution du taux de réadmission concernaient des patient-es ne souffrant que d'une seule pathologie. Partant de ce constat, nous avons identifié la population qui pourrait le plus bénéficier de soins de transition, dans le cadre du projet INSTEAD, par un consensus incluant d'une part des patient-es et, d'autre part, des professionnel-les hospitaliers et communautaires. Pour assurer la continuité des soins, il s'avère nécessaire de prendre en compte la perception de la personne, sa compréhension ainsi que les changements influençant son plan de soins à domicile. Pour ce faire, une collaboration interprofessionnelle est indispensable.

RESUMEN

PURPOSE: To investigate magnetization transfer (MT) effects as a new source of contrast for imaging and tracking of peripheral foot nerves. MATERIALS AND METHODS: Two sets of 3D spoiled gradient-echo images acquired with and without a saturation pulse were used to generate MT ratio (MTR) maps of 260 µm in-plane resolution for eight volunteers at 3T. Scan parameters were adjusted to minimize signal loss due to T2 dephasing, and a dedicated coil was used to improve the inherently low signal-to-noise ratio of small voxels. Resulting MTR values in foot nerves were compared with those in surrounding muscle tissue. RESULTS: Average MTR values for muscle (45.5 ± 1.4%) and nerve (21.4 ± 3.1%) were significantly different (P < 0.0001). In general, the difference in MTR values was sufficiently large to allow for intensity-based segmentation and tracking of foot nerves in individual subjects. This procedure was termed MT-based 3D visualization. CONCLUSION: The MTR serves as a new source of contrast for imaging of peripheral foot nerves and provides a means for high spatial resolution tracking of these structures. The proposed methodology is directly applicable on standard clinical MR scanners and could be applied to systemic pathologies, such as diabetes.
