Training using a simulation-based workshop reduces inaccuracies in estimations of testicular volume.

OBJECTIVES: Measuring testicular volume (TV) by orchidometer is routine in the clinic when staging male puberty. We have developed a simulation model for TV estimation and investigated whether training medical students, using a workshop with simulation models, could improve the accuracy and reliability of TV estimation. METHODS: All participating medical students watched a video representing standard undergraduate training in male pubertal assessment. Volunteers were then randomised directly to assessment or to attend a workshop consisting of a further video and four stations contextualising and practising the skills required for TV estimation, prior to assessment. Three child mannequins displaying testes of 3 mL, 4 mL (twice), 5, 10 and 20 mL were used for assessment. Participants were asked to return a fortnight later for repeat assessment to assess intra-observer reliability, the effect of repeated examinations on accuracy and time on skill retention. RESULTS: Ninety students participated (55F), 46 attended the workshop and were considered "trained". There was no difference between the groups in numbers of correct estimations (29% trained, 27% untrained, p=0.593). However, the trained group's estimations were closer to the true volume, with more from the trained group one bead away (p=0.002) and fewer more than three beads away from the true volume (p<0.001), compared to the untrained group. Trained participants were more accurate at the second assessment (n=80) (p<0.001) and had greater intra-observer reliability (p=0.004). CONCLUSIONS: Overall TV estimation accuracy was poor. Workshop-style training improved accuracy, reliability and retention of skill acquisition and could be considered as a useful learning tool.

Implementation of a Standardized Discharge Time-out Process to Reduce Prescribing Errors at Discharge.

BACKGROUND: To reduce prescribing errors occurring on discharge from the hospital, a standardized discharge time-out process was implemented on a general medicine service at Wake Forest Baptist Medical Center. In the time-out process, the multidisciplinary care team reviewed the patient's medical records together to determine the optimal discharge medication regimen. This regimen was recorded on a time-out form and then was used to develop the patient's discharge documents. OBJECTIVE: To evaluate the impact of a standardized discharge time-out process on prescribing errors that occur as patients are discharged from a general medicine service. METHODS: The medical records of all patients discharged from a general medicine service during 60-day periods before ("pre-group") and after ("post-group") implementation of a standardized discharge time-out process were retrospectively reviewed by an internal medicine physician to determine the presence of discharge prescribing errors. RESULTS: There were 142 and 124 evaluable patients in the pre- and post-groups, respectively. Compliance with the time-out process was 93% in the post-group. At least 1 prescribing error was detected in 49 (34.5%) of the discharges in the pre-group and 17 (13%) of the discharges in the post-group (P < .0001). All of the errors noted in the post-group occurred in discharges in which a clinical pharmacist was not involved. CONCLUSIONS: A multidisciplinary, standardized discharge time-out process was associated with a dramatic reduction in prescribing errors when patients were discharged from a general medicine service. The time-out process is one strategy to improve patient safety at hospital discharge.
