ABSTRACT
Objective To investigate the effect of a short surgical skills course on general practitioners' confidence levels to perform procedural skills. Design Prospective observational study. Setting The Clinical Evaluation and Training Centre, a practical skills-based educational facility, at The University of Western Australia. Participants Medical practitioners who participated in these courses. Nurses, physiotherapists, and medical students were excluded. The response rate was 61% with 61 participants providing 788 responses for pre- and postcourse confidence levels regarding various surgical skills. Intervention One- to two-day surgical skills courses consisting of presentations, demonstrations, and practical stations, facilitated by specialists. Main Outcome Measures A two-page precourse and postcourse questionnaire was administered to medical practitioners on the day. Participants rated their confidence levels to perform skills addressed during the course on a 4-point Likert scale. Results Of the 788 responses regarding confidence levels, 621 were rated as improved postcourse, 163 were rated as no change, and 4 were rated as lower postcourse. Seven of the courses showed a 25% median increase in confidence levels, and one course demonstrated a 50% median increase. All courses showed statistically significant results ( p < 0.001). Conclusion A short surgical skills course resulted in a statistically significant improvement in the confidence levels of rural general practitioners to perform these skills.
ABSTRACT
BACKGROUND: Sun exposure is associated with several ophthalmic diseases, including pterygium which may develop in adolescence. This study reports the prevalence of pterygium and its associations in a large cohort of young Australian adults. Conjunctival ultraviolet autofluorescence, a biomarker of ocular sun exposure, has recently been characterized in some Australian populations. DESIGN: Cross-sectional population-based study. PARTICIPANTS: One thousand three hundred forty-four subjects aged 18-22 years in the Western Australian Pregnancy Cohort (Raine) Study. METHODS: Standardized colour and ultraviolet autofluorescence photographs of the nasal and temporal conjunctiva were taken, and assessed for presence of pterygium and area of autofluorescence. Sun exposure and protective factors were assessed by structured questionnaire. MAIN OUTCOME MEASURES: Area of conjunctival ultraviolet autofluorescence in square millimetre (mm(2)) and presence of pterygium. RESULTS: Median total conjunctival autofluorescence was 44.2 mm(2) (interquartile range 20.2-69.8 mm(2)). Median conjunctival autofluorescence was higher in nasal than in temporal quadrants (23.8 mm(2) vs. 18.9 mm(2), P < 0.001), but did not differ according to age or gender. Higher body mass index was associated with lower levels of autofluorescence. Total autofluorescence increased with increasing time spent outdoors. Prevalence of pterygium was 1.2% (95% confidence interval 0.6-1.8%), and was associated with male gender (odds ratio 6.71, P = 0.012). Participants with pterygium had significantly more conjunctival autofluorescence than those without (median 73.4 mm(2) vs. 44.0 mm(2), P = 0.001). CONCLUSIONS: Conjunctival ultraviolet autofluorescence is associated with increased time spent outdoors, and increased prevalence of pterygium. The association of this biomarker with other ophthalmohelioses, including cataract, ocular surface squamous neoplasia and eyelid malignancy, has yet to be determined.
