Deconstructing forearm casting task by videos with step-by-step simulation teaching improved performance of medical students: is making working student's memory work better similar to a process of artificial intelligence or just an improvement of the prefrontal cortex homunculus?

PURPOSE: To compare two teaching methods of a forearm cast in medical students through simulation, the traditional method (Trad) based on a continuous demonstration of the procedure and the task deconstruction method (Decon) with the procedure fragmenting into its constituent parts using videos. METHODS: During simulation training of the below elbow casting technique, 64 medical students were randomized in two groups. Trad group demonstrated the entire procedure without pausing. Decon group received step-wise teaching with educational videos emphasizing key components of the procedure. Direct and video evaluations were performed immediately after training (day 0) and at six months. Performance in casting was assessed using a 25-item checklist, a seven item global rating scale (GRS Performance), and a one item GRS (GRS Final Product). RESULTS: Fifty-two students (Trad n = 24; Decon n = 28) underwent both day zero and six month assessments. At day zero, the Decon group showed higher performance via video evaluation for OSATS (p = 0.035); GRS performance (p < 0.001); GRS final product (p < 0.001), and for GRS performance (p < 0.001) and GRS final product (p = 0.011) via direct evaluation. After six months, performance was decreased in both groups with ultimately no difference in performance between groups via both direct and video evaluation. Having done a rotation in orthopaedic surgery was the only independent factor associated to higher performance. CONCLUSIONS: The modified video-based version simulation led to a higher performance than the traditional method immediately after the course and could be the preferred method for teaching complex skills.

The use of adhesive elastic tape for hand oedema control in patients with a wrist fracture treated in a cast: A pilot study.

BACKGROUND: The adhesive elastic tape use is indicated for controlling oedema, although currently there is not the definitive evidence regarding its effectiveness. Wrist fractures are a frequent occurrence, often leading to oedema development in patients treated with forearm casts. This pilot study aims to investigate the effects of elastic tape in controlling hand oedema among patients with forearm casts for wrist fractures and the feasibility of a future randomized controlled trial. METHODS: The study was conducted on adult patients with unilateral conservatively treated wrist fracture. The tape was applied to the intervention group after cast application, while the control group received the standard treatment. The circumference difference between baseline and the 7-day follow-up of both the 1st finger and the remaining 4 fingers merged together was evaluated. Ethical approval for the study has been obtained. RESULTS: 23 participants were enrolled. The intervention group showed a higher reduction in finger circumferences compared to the control group (median difference T1-T0 No tape vs Tape: 0 cm vs -0.2 cm for the 1st finger and 0.5 cm vs -0.5 cm for the remaining 4 fingers), although the changes were not statistically significant. CONCLUSION: Although the number of enrolled patients was limited due to Covid-19 pandemic, the study results suggest a potential reduction in oedema after the use of adhesive elastic tape, justifying the needed of a future full-scale study. Given its low cost and ease of use, we believe that tape can be considered in clinical practice. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04683887.

Randomised controlled prospective study of the use of adhesive elastic tape for the control of hand oedema in patients with a wrist fracture treated in a cast: a study protocol.

BACKGROUND: Wrist fractures are a common occurrence, affecting patients of all ages. Wrist fracture patients often develop oedema and the presence of a cast increases the risk. The use of adhesive elastic tape is indicated for oedema control, but there is no definitive evidence of its effectiveness. This study aims to evaluate the effectiveness of the tape in control of hand oedema in wrist fracture patients with a forearm cast. METHODS: We present a study protocol for a randomised controlled trial with blinded data processing. We will apply the tape to the intervention group after cast application, while the control group will receive the standard treatment. We will evaluate the circumference difference between baseline (T0) and the 7-day follow-up (T1) of both the thumb and of the other 4 fingers merged together. We will collect data regarding re-attendance to the Orthopedic Emergency Room due to "intolerance to the plaster cast". Sample size calculations resulted in a required total of 220 participants (110 per group). Ethical approval for the study has been obtained. DISCUSSION: We aim to demonstrate that the use of tape improves the tolerability of the cast by reducing the oedema formation, the feeling of constriction and pain.
