Impact of a Hybrid-Virtual Teaching Model on the Physical Examination Skills of Fourth-Year Medical Students.

ABSTRACT: A required fourth-year advanced core neurology-physical medicine and rehabilitation clerkship was adapted to hybrid format (2-wk remote; 2-wk in-person) during the COVID-19 pandemic. With teaching of the neurological physical examination being shifted to the remote component, we sought to determine whether this negatively affected student performance on an Objective Structured Clinical Examination, particularly the physical examination component. Mean pandemic-era total Objective Structured Clinical Examination scores ( n = 79, 85.1 ± 7.3) were similar to prepandemic era ( n = 137, 83.5 ± 6.0, P = 0.082). Pandemic-era physical examination scores were slightly higher than prepandemic (86.9 ± 6.5 vs. 84.9 ± 6.6). Despite conversion of the clerkship to a hybrid curriculum, the performance of the students on the Objective Structured Clinical Examination and the physical examination were unchanged. Reasons for this lack of change may include the constructiveness and integration of the case-based virtual demonstrations combined with in-person learning or the flexibility of the virtual course to allow students more time to prepare for the Objective Structured Clinical Examination and the physical examination. Our findings demonstrate that a hybrid-virtual model can be used to teach foundational skills such as the basics of the physical examination, while allowing faculty to address higher-order skills such as integration of clinical data with medical knowledge.

Changing clinical patterns of Rhegmatogeneous Retinal Detachments during the COVID19 pandemic lockdown in the North West of the UK.

INTRODUCTION: The UK Government imposed a COVID19 lockdown (LD) restricting all but essential activities from 24th March 2020. Subsequently, there has been a significant reduction in casualty attendances nationwide including for ophthalmic emergencies. We aim to study the presentation of rhegmatogenous retinal detachments (RRD) and significant vitreous haemorrhage caused by posterior vitreous detachment (PVD-VH) in three tertiary centres covering most of the North West of England in the 6 weeks before and during the lockdown. METHODS: A retrospective multicenter non-randomised consecutive case series study was designed to collect information on all cases of RRD and PVD-VH requiring surgery presenting to the vitreoretinal departments of Manchester Royal Eye Hospital, East Lancashire NHS Foundation Trust and the Lancashire NHS Foundation Trust from 11th February to 4th May 2020. RESULTS: A total of 137 eyes of 137 patients were identified between the three centres of which 132 eyes were operated for RRD. Of these, 86 (64.7%) were operated pre-LD compared with 46 eyes (34.8%) during LD. Forty-five out of 86 eyes (52.3%) were macula-off pre-LD compared with 31 out of 46 eyes (67.3%) during LD (p = 0.06). There was lower proportion of non-PVD related RRD during LD (11 pre-LD to 1 during LD, p = 0.05). PVR was present in four cases during LD compared to 2 before (p = 0.19). CONCLUSION: There was a clinically significant reduction in the overall incidence of RRD in our centres with an increase in the proportion of macula-off and proliferative vitreoretinopathy during the LD period compared to a similar period before.
