Making portfolios work in practice.

BACKGROUND: A portfolio captures learning from experience, enables an assessor to measure student learning, acts as a tool for reflective thinking, illustrates critical analytical skills and evidence of self-directed learning and provides a collection of detailed evidence of a person's competence. AIMS: This paper reports data on how assessors and nursing students match learning outcomes and/or competencies to their practice and then reconstruct those experiences into the format required by the portfolio documentation. The data were gathered as part of a larger study to evaluate the use of portfolios in the assessment of learning and competence in England. METHODS: This three phase stakeholder evaluation was designed to gain the views of those involved in designing, implementing and using portfolios in nurse education. In phase 2, 122 students and 58 nurse teachers were interviewed about their perceptions of portfolio use, and a further 32 students and 26 assessors were interviewed after they had been observed taking part in an assessment process. Thematic data analysis was used. FINDINGS: Assessors and students underwent a complex process of deconstructing learning outcomes/competences to fit these to their practice. These then had to be reconstructed through the written medium to fit the structure of the portfolio. Confirmation that this met teachers' expectations was essential to allay feelings of insecurity. CONCLUSIONS: To achieve maximum benefit from the portfolio as a learning tool to link theory and practice, there needs to be a clear fit between the model of portfolio and the professional practice that is to be assessed. Outcomes and competences, as well as the type of evidence required to demonstrate their achievement, and integration of the whole experience should match the students' stage of professional and academic development. Over-complex approaches to practice assessment, particularly in the early stages of students' careers, can detract from clinical learning in favour of learning how to complete the portfolio successfully.

Ultrasound diagnosis of craniosynostosis.

OBJECTIVE: To retrospectively study prenatal ultrasound images of patients with craniosynostosis to determine the extent to which prenatal diagnosis is possible. METHOD: Prenatal ultrasound images of 19 patients with postnatally diagnosed metopic or coronal suture craniosynostosis were retrospectively reviewed. The 26 ultrasound examinations obtained were compared with normal images and tables of gestation. RESULTS: It was not possible to diagnose craniosynostosis in the first trimester. In the second trimester, Kleeblattschädel was diagnosed at 20.5 weeks. A multilobular shape to the skull and diastasis of the frontotemporal suture was identified. In a second child with Kleeblattschädel, the cephalic index was above normal 86.4 (normal range 70 to 86), and the head circumference to abdominal circumference was increased. In the third trimester, the head shape deformation was more obvious. Brachycephaly diagnosis was made in the second trimester. In Crouzon syndrome the hypertelorism was identified at 19.9 weeks. Plagiocephaly was diagnosed at 21.4 weeks. In trigonocephaly the reduced cephalic index was noted at 18.8 weeks. In the third trimester, the deformity was diagnosed in all cases. CONCLUSION: No diagnosis of craniosynostosis was made in the first trimester. In the second trimester, it was possible to diagnose Kleeblattschädel, trigonocephaly, brachycephaly (bilateral coronal suture craniosynostosis), and plagiocephaly (unilateral coronal suture craniosynostosis) in nine of the examinations. In the third trimester and at term, it was possible to diagnose previously listed conditions from six of the seven examinations obtained. Kleeblattschädel was suspected during original examination. A total of 15 examinations of 26 were correctly diagnosed during this investigation.
