  • The Effect of Positive and Negative Verbal Feedback on Surgical Skills Performance and Motivation JOURNAL OF SURGICAL EDUCATION Kannappan, A., Yip, D. T., Lodhia, N. A., Morton, J., Lau, J. N. 2012; 69 (6): 798-801

    Abstract

    There is considerable effort and time invested in providing feedback to medical students and residents during their time in training. However, little effort has been made to measure the effects of positive and negative verbal feedback on skills performance and motivation to learn and practice. To probe these questions, first-year medical students (n = 25) were recruited to perform a peg transfer task on Fundamentals of Laparoscopic Surgery box trainers. Time to completion and number of errors were recorded. The students were then randomized to receive either positive or negative verbal feedback from an expert in the field of laparoscopic surgery. After this delivery of feedback, the students repeated the peg transfer task. Differences in performance pre- and post-feedback and also between the groups who received positive feedback (PF) vs negative feedback (NF) were analyzed. A survey was then completed by all the participants. Baseline task times were similar between groups (PF 209.3 seconds; NF 203 seconds, p = 0.58). The PF group averaged 1.83 first-time errors while the NF group 1 (p = 0.84). Post-feedback task times were significantly decreased for both groups (PF 159.75 seconds, p = 0.05; NF 132.08 seconds, p = 0.002). While the NF group demonstrated a greater improvement in mean time than the PF group, this was not statistically significant. Both groups also made fewer errors (PF 0.33 errors, p = 0.04; NF 0.38 errors, p = 0.23). When surveyed about their responses to standardized feedback scenarios, the students stated that both positive and negative verbal feedback could be potent stimulants for improved performance and motivation. Further research is required to better understand the effects of feedback on learner motivation and the interpersonal dynamic between mentors and their trainees.

  • Epidemiology of Non-Vehicular Trauma Patients in the Prehostpial Setting in India Matthew Strehlow, S. Mahadevan

    Background: Non-vehicular trauma (NVT) accounts for 8% of all calls to the GVK Emergency Management and Research Institute (EMRI), which provides prehospital emergency care to 85 million residents of Andhra Pradesh, India. This study describes the characteristics and outcomes of patients with NVT transported by GVK EMRI.
    Methods: All patients with NVT were prospectively enrolled over 28 12-hour periods (equally distributed over each hour of the day and day of the week) during July/August 2010. Patients not found at the scene, refusing service, or reporting self-inflicted injuries were excluded. Real-time demographic and clinical data were collected from prehospital care providers using a standardized questionnaire. Follow-up patient information was collected at 48-hours and 30-days following injury.
    Results: A total of 1,569 patients were enrolled. Follow-up rates were 72% at 48 hours and 71% at 30 days. The mean patient age was 40 (SD = 18) and 67% were male. Adults (ages 18–64) accounted for most patients (80%), followed by elderly (age > 64, 12%) and children (age < 18, 8%). Of the patients, 71% were from rural/tribal areas and 89% from lower socioeconomic strata. Eighty-two percent called within 1 hour of injury. Median call-to-scene time was 19 minutes (SD = 15) and scene-to-hospital time was 25 minutes (SD = 21). Most patients suffered blunt injuries (85%) with falls accounting for 43% of all injuries. Of the injuries, 56% were accidents and 43% assaults. Most injuries involved head/neck (48%) and extremities (44%). Cumulative mortality rates prior to hospital arrival, at 48-hours and at 30-days were 1.1%, 3.2%, and 4.9% respectively. Falls accounted for 69% of all deaths. Falls and age > 65 were predictors of mortality (p < 0.0001). Of NVT survivors, 56% returned to baseline function and 28% were in significant pain or bed bound at 30-days post-injury.
    Conclusion: This initial study of prehospital NVT patients in India reveals that falls and elderly age were highly associated with death.
