RESUMO
Various workplace-based assessment tools are available, but none have been shown to improve performance in procedural skills. This study aimed to assess the impact of using one such tool, cumulative sum charts, on procedural skill ability. A single-blind randomised controlled trial was conducted on 82 final year medical students. Control group students received the usual teaching; in addition to this, intervention group students were provided with cumulative sum charts to log their cannulation attempts over a 7-month period. At the end of the year, students from both groups undertook a validated test of automaticity of cannulation skill. Students in the intervention group obtained median (IQR [range]) scores of 68.2 (60.5-74.3 [42.7-81.1]) vs 62.2 (52.2-68.8 [40.7-80.5]) for the control group (p = 0.013). The effect size was moderate (Cohen's d = 0.608). This study therefore provides support for the hypothesis that use of cumulative sum charts improves performance when learning procedural skills.

AIM: To design, develop and test a system for analysis of photic phenomena. METHOD: Extensive background research, patient interviews and theoretical studies led to development of a set of photographic images resembling photic phenomena experienced by patients. These photographic images were processed and digitally altered to create scales of severity for each photic phenomenon in which patients indicated their severity of symptoms by choice of image. The system was tested for stability and validity. RESULTS: The system showed excellent repeatability and reliability. Face, content, criterion and construct validity were all found to be acceptable. CONCLUSION: The photographic images of photic phenomena analyser is an acceptable, validated measure for the assessment of photic phenomena, in both pseudophakic patients and those with cataract.
