Radiography students' perceptions of Peer assisted learning.

INTRODUCTION: Peer Assisted Learning (PAL) is collaborative learning in which students from the same or different academic levels learn from each other. It is meant to support the regular teaching and learning process. Learning in PAL can be explained by constructive social learning theories and has many advantages such as, students' perception of it and the ease of discussion between peers. This study aims to measure students' perception of PAL in the context of radiography education. METHODS: A PAL programme was implemented in one module taught to second year radiography students. A questionnaire was then distributed to the participating students (n = 28) to measure their perception of PAL; the questionnaire consisted of 13 questions with a Likert scale of 5 (1 = strongly disagree to 5 = strongly agree). The results were analysed using SPSS to calculate the percentages, means, standard deviations, and factorial analysis. RESULTS: Twenty-six students responded to the questionnaire (92.8%). The range of agreement in all questionnaire items ranged from 79.9% to 92.3%. The factor analysis revealed two main factors affecting students' acceptability. PAL enriched students' learning experience and helped them in preparation for exams. CONCLUSION: The use of PAL is highly acceptable by students in context of radiography education. IMPLICATIONS FOR PRACTICE: More studies are necessary to confirm the best methods of using PAL. These may involve both students and educators, and pre- and post-methods.

AMEE Guide No. 123 - How to read studies of educational costs.

Healthcare and health professions education share many of the same problems in decision making. In both cases, there is a finite amount of resources, and so choices need to be made between alternatives. To navigate the options available requires effective decision making. Choosing one option requires consideration of its opportunity cost - the benefit forgone of the other competing options. The purpose of this abridged AMEE guide is to introduce educational decision-makers to the economic concept of cost, and how to read studies about educational costs to inform effective cost-conscious decision-making. This guide leads with a brief review of study designs commonly utilized in this field of research, followed by an overview of how study findings are commonly presented. The tutorial will then offer a four-step model for appraising and considering the results of an economic evaluation. It asks the questions: (1) Can I trust the results? (2) What are the results telling me? (3) Could the results be transferred to my context? (4) Should I change my practice?

Diagnostic radiography students' perceptions of formative peer assessment within a radiographic technique module.

INTRODUCTION: Assessment is a central part of student learning. Student involvement in peer assessment leads to significant improvement in students' performance, supports students' learning, promotes the development of evaluation skills and encourages reflection. AIM: The aim of this study is to assess perceptions of the Formative Peer Assessment (FPA) initiative within a higher education setting for undergraduate radiography students. METHODS: Qualitative action research was conducted. Students were allowed to anonymously assess each other's assignments using a standardized evaluation sheet that they had been trained to use. Participants' perceptions were assessed through focus group discussion. RESULTS: The findings showed that students' experiences with peer assessment were positive. Students acknowledged that they received valuable feedback and learned from assessing their peers. Students recommended the need for training and suggested using more than one evaluator. CONCLUSION: The FPA initiative in the study institution believed to be succeed as the students had a positive experience with the FPA. Students learnt from PA and from self-assessment. Implementation of PA will promote reflection and critical thinking and problem solving skills, that are important traits in radiography graduate profile as in radiography clinical practice the professional require to modify imaging techniques and critique images to ensure the quality of care.

Susceptibility to antimicrobials of mastitis-causing Staphylococcus aureus, Streptococcus uberis and Str. dysgalactiae from New Zealand and the USA as assessed by the disk diffusion test.

OBJECTIVE: To compare the antimicrobial susceptibility patterns of three common mastitis pathogens (Staphylococcus aureus, Streptococcus uberis and Str. dysgalactiae) isolated from milk samples from New Zealand and the USA. METHODS: A total of 182 S. aureus, 126 Str. uberis and 89 Str. dysgalactiae isolates from New Zealand (107, 106 and 41, respectively) and the USA (75, 20 and 48, respectively) were assessed using the disk diffusion test. RESULTS: Susceptibility varied among the bacterial species. All isolates were susceptible to the amoxicillin-clavulanic acid combination. Resistance to lincomycin was most frequent (susceptibility of 8.6%) across all species. Non-susceptible (i.e. resistant or intermediate) isolates of S. aureus were identified for the three non-isoxazolyl penicillins (amoxicillin, ampicillin and penicillin: 20.6% and 36.0%) and lincomycin (99.9% and 94.6%) for NZ and the USA, respectively. Resistance to erythromycin (5.3%) and tetracyclines (6.7%) was detected only in isolates from the USA. There were differences in susceptibility between Str. uberis and Str. dysgalactiae; all streptococcal isolates demonstrated resistance to aminoglycosides (neomycin 52.4% and streptomycin 27.9%) and enrofloxacin (28%). Resistance of Str. dysgalactiae to tetracycline was almost 100.0% and to oxytetracycline 89.9%. CONCLUSION AND CLINICAL RELEVANCE: Most of the isolates tested were susceptible to most of the antimicrobials commonly used for treatment of bovine mastitis, with the exception of the lincosamides. Susceptibility to a selected class-representative antimicrobial and at the genus level should be interpreted with caution. Differences between NZ and the USA confirm the value of national surveys to determine the susceptibility patterns of mastitis pathogens.

Overview of medical schools in the Eastern Mediterranean Region of the World Health Organization.

The 22 countries of the Eastern Mediterranean Region (EMR) exhibit considerable diversity, both culturally and economically. This paper collated published data on the status of medical schools in the Region to provide information to assist in future planning. Information about medical schools was obtained from the International Medical Education Directory, the Avicenna Directory, the WHO/EMR Health Professions Education Directory and the Institute for International Medical Education's Database of Medical Schools. The registered number of medical schools in the Region varied according to the different directories. There were variations in the language used for instruction (some used more than one language) and the density of medical schools per million population. The density and number of medical schools in the country were not related to the number of working physicians which ranged from 2.1 per 10 000 population in Afghanistan to 28.3 in Egypt. An updated directory of medical schools in the Region is much needed.

Use of the Internet by Sudanese doctors and medical students.

Patterns of use of the Internet were investigated by a questionnaire survey of 102 hospital doctors and 123 medical students in Khartoum, Sudan, in January 2005. More doctors (84.3%) had used the Internet than had students (78.9%). Half of consultants (55.0%) used the Internet daily, compared with only 18.2% of junior doctors. Many consultants and junior doctors rated their abilities as poor (60.0% and53.1%). One-third of students (33.3%) used the Internet only for personal and not for academic purposes. Barriers to greater use of the Internet by doctors included: time constraints (80.2%), poor skills (54.6%), no access to full texts of journal articles (53.4%), difficulty in verifying the quality of information (47.6%) and high costs (41.8%). Students faced similar barriers but also listed poor knowledge of the English language.

Deficiencies in medical prescriptions in a Sudanese hospital.

We determined the quality of medical prescription in Ribat University Hospital, Khartoum through detecting errors in doctors' prescriptions. We randomly selected 1000 medical prescriptions and checked them for completeness and legibility. The total number of doctors responsible for writing the prescriptions was 46. The patient's full name was written on only 18.8% of prescriptions and that of the doctor on only 6.7%. In only 19.5% of prescriptions were drugs prescribed by their generic names, 59.7% lacked the quantity of the drug, 25.7% lacked the duration of treatment and 15.8% were difficult to read. The quality of drug prescriptions written by our hospital doctors is seriously deficient.

Attitudes towards euthanasia and assisted suicide among Sudanese doctors.

An anonymous questionnaire was used to survey the attitudes of 382 doctors towards euthanasia and assisted suicide at Khartoum's two main hospitals. Of the 382, 248 responded (65% response rate). The mean age was 38 +/- 13.5 years; male:female ratio was 130:118; 66% were house staff, 34% specialists; 92% Muslim, 8% Christian. The vast majority (85%) strongly opposed the practices, while 15% thought they should be performed only in certain situations, subject to strict safeguards. Reasons given for opposition included religious beliefs, inconsistency with the doctor's role, presence of subtle pressures on patients, and potential for misuse among the physically and intellectually handicapped.
