Comparing modified Lee and White method against 20-minute whole blood clotting test as bedside coagulation screening test in snake envenomation victims

Abstract Background: Twenty-minute whole blood clotting test (20WBCT) and Modified Lee and White (MLW) method are the most routinely employed bedside tests for detecting coagulopathic snake envenomation. Our study compared the diagnostic utility of MLW and 20WBCT for snakebite victims at a tertiary care hospital in Central Kerala, South India. Methods: This single-center study recruited 267 patients admitted with snake bites. 20WBCT and MLW were performed simultaneously at admission along with the measurement of Prothrombin Time (PT). The diagnostic utility of 20WBCT and MLW was determined by comparing the sensitivity (Sn), specificity (Sp), positive and negative predictive values, likelihood ratios, and accuracy at admission with an INR value > 1.4. Results: Out of 267 patients, 20 (7.5%) patients had VICC. Amongst those who had venom-induced consumption coagulopathy (VICC), MLW was prolonged for 17 patients, (Sn 85% 95% confidence interval [CI]: 61.1-96.0) whereas 20WBCT was abnormal for 11 patients (Sn 55%, 95% CI: 32.04-76.17). MLW and 20WBCT were falsely positive for the same patient (Sp 99.6%, 95% CI: 97.4-99.9%). Conclusion: MLW is more sensitive than 20WBCT to detect coagulopathy at the bedside amongst snakebite victims. However, further studies are necessary for standardizing bedside coagulation tests in snakebite cases.

The gaps in undergraduate medical education due to the ongoing pandemic: An experience from a private medical college in Kerala

The Covid-19 pandemic affected undergraduate medical education worldwide. By March 2020, colleges in India had to close following a national lockdown. Most of the colleges including ours started using e-platforms. Our earlier studies highlighted concern for lack of patient examination in clinical settings and successes of the online teaching programmes were limited to didactic teaching. The year 2020 also was the year in which the National Medical Commission (NMC) introduced a competency-based system, which was new to all stakeholders. We assessed the impact of Covid-19 on the ongoing teaching pattern in our institute. Actual coverage of theory classes and practical/clinical teaching sessions were gathered from departments across all years of undergraduate medical education and the gap percentage was calculated against the NMC/ Medical Council of India requirements. The gap percentage was calculated as missing classes divided by required classes multiplied by hundred. The heads of departments were consulted, and details of theory, practical and clinical classes taken for each batch before and after lockdown were gathered using a questionnaire. These were compared against the mandated teaching by the NMC guideline for theory, practical and clinics. The results showed a gap ranging from 2% to 83% for theory classes, the least being in anatomy and the highest being in medicine. As there were no practical or clinical sessions during the lockdown, the gap was zero. Various challenges were faced due to online medical education. There was a dilemma over choosing the type of training that would produce adequate numbers with low quality or a delayed training but of assured quality. Various solutions including suspending the ongoing course and converting it to short-term skill training sessions to deal with pandemic care and strategies to improve online teaching were considered.
