Interprofessional education in a student-led emergency department: A realist evaluation.

This article reports a realist evaluation undertaken to identify factors that facilitated or hindered the successful implementation of interprofessional clinical training for undergraduate students in an emergency department. A realist evaluation provides a framework for understanding how the context and underlying mechanisms affect the outcome patterns of an intervention. The researchers gathered both qualitative and quantitative data from internal documents, semi-structured interviews, observations, and questionnaires to study what worked, for whom, and under what circumstances in this specific interprofessional setting. The study participants were medical, nursing, and physiotherapy students, their supervisors, and two members of the emergency department's management staff. The data analysis indicated that the emergency ward provided an excellent environment for interprofessional education (IPE), as attested by the students, supervisors, and the clinical managers. An essential prerequisite is that the students have obtained adequate skills to work independently. Exemplary conditions for IPE to work well in an emergency department demand the continuity of effective and encouraging supervision throughout the training period and supervisors who are knowledgeable about developing a team.

Interprofessional clinical training for undergraduate students in an emergency department setting.

Interprofessional education (IPE) for teams of undergraduate students has since 1999 been carried out at the orthopedic emergency department at the Karolinska University Hospital. During a 2-week period, teams of medical, nursing and physiotherapy students practice together. With the aim of training professional and collaboration skills, the teams take care of patients with varying acute complaints, under the guidance of supervisors from each profession. This study describes the educational model and compares the attitudes of the different student categories participating in this unique IPE model. All students who participated in this experience during the period 2008-2010 were asked to fill in a questionnaire on completion of their training period. Results showed that all three categories, with no significant difference, highly appreciated the setting and the team training. Results also showed that the training significantly increased the students' knowledge of their own professional role as well as their knowledge of the other professions. We conclude that training at an emergency department can provide excellent opportunities for interprofessional team training for undergraduate students. The teamwork enhances the students' understanding of the professional roles and can contribute to a more holistic approach to patient care.

Variation in the position of the elbow flexion axis after total joint replacement with three different prostheses.

The instantaneous flexion axes in rheumatoid patients treated with a Kudo (Biomet UK Ltd, Swindon, UK), Capitellocondylar (Johnson & Johnson Orthopaedics Inc, Raynham, MA), or GSB III (Zimmer GmbH, Winterthur, Switzerland) elbow prosthesis were calculated using radiostereometric analysis and compared with those previously found in the normal elbow in vivo. Variability in the flexion axis position was greater in the prosthetic elbows than reported for healthy subjects. This was especially evident for the unlinked Kudo prosthesis, with dispersions of the axes up to 84.3 degrees in the frontal and 45.0 degrees in the horizontal plane. Corresponding values for the unlinked Capitellocondylar prosthesis were 19.7 degrees and 20.9 degrees. The linked GSB III prosthesis was the most constrained, with dispersions within 15.4 degrees in the frontal and 4.6 degrees in the horizontal plane. The unlinked elbow prostheses displayed considerable axis dispersion under physiologic conditions. Implant design seems to be able to compensate for this to some extent, as indicated, for example, by the results of the Capitellocondylar prosthesis.

Radial head prosthesis after fracture of radial head with associated elbow instability.

INTRODUCTION: Fractures of the radial head and associated elbow instability can be treated with operation with radial head prosthesis. In this study, we evaluate function 1-7 years after implantation and also function after removal of five prostheses. MATERIAL AND METHODS: Eighteen patients with radial head fracture and associated elbow instability were evaluated 3.7 years (1-7) after implantation of a radial head prosthesis. Pain at rest and during activity was measured with a visual analogue scale (VAS). Test of stability and neurological examination was done manually as well as measurement of the range of motion, using a goniometer. Activity of daily living (ADL) was estimated using five questions where the answers were graded between 1 and 3. The patients were asked to grade their general satisfaction according to the following scale; very satisfied, satisfied, not satisfied, disappointed. Plain X-rays were taken and 14 patients agreed to have their elbow strength evaluated using the validated BTE work simulator. RESULTS: Five prostheses had been extracted due to poor range of motion. All these patients improved after extraction. All elbows were stable. No patient with extracted prosthesis had VAS score >2. The mean extension defect for this group was 15 degrees (5-25) compared to the mean extension defect for the 13 patients with the prosthesis still in place 15 degrees (0-40). The highest VAS score for the patients with prosthesis was five but the mean as low as 0.8. In the whole group, 13 patients were pain free. ADL function was good in general. The X-rays of the prostheses, still in place, showed radiolucent lines in 7 of the 13 patients. In the whole group, there was a significant decrease in supination, flexion and extension strength (P<0.01, P<0.01, P<0.05). DISCUSSION: Radial head prosthesis works as a spacer after fracture of the radial head and associated instability. If range of motion is much restricted post-operatively, the prosthesis can be removed with improved function as result.
