Otoskills training during covid-19 pandemic: a before-after study.

ABSTRACT:

Background

The ongoing COVID-19 pandemic has disrupted the surgical training of residents. There is a real concern that trainees will not be able to meet their training requirements. Low-fidelity surgical simulation appears to be an alternative for surgical training. The educational benefits of repeating ossiculoplasty simulations under a microscope have never been evaluated. With this study we aimed to evaluate the differences in performance scores and on a global rating scale before and after training on an ossiculoplasty simulator.

Methods

In this quasi-experimental, prospective, single-centre, before-after study with blinded rater evaluation, residents performed five microscopic ossiculoplasty tasks with a difficulty gradient (sliding beads onto rods, the insertion of a partial prosthesis, the insertion of a total prosthesis, and the insertion of a stapedotomy piston under microscopic or endoscopic surgery) before and after training on the same simulator. Performance scores were defined for each task, and total performance scores (score/min) were calculated. All data were collected prospectively.

Results

Six out of seven intermediate residents and 8/9 novices strongly agreed that the simulator was an effective training device and should be included in the ENT residency program. The mean effect of training was a significant increase in the total performance score (+ 0.52 points/min, [95 % CI, 0.40-0.64], p < 0.001), without a significant difference between novice and intermediate residents.

Conclusions

This preliminary study shows that techniques for middle-ear surgery can be acquired using a simulator, avoiding any risk for patients, even under lockdown measures.

Project description:BackgroundThe COVID-19 pandemic has led to a notable increase in telemedicine adoption. However, the impact of the pandemic on telemedicine use at a population level in rural and remote settings remains unclear.ObjectiveThis study aimed to evaluate changes in the rate of telemedicine use among rural populations and identify patient characteristics associated with telemedicine use prior to and during the pandemic.MethodsWe conducted a repeated cross-sectional study on all monthly and quarterly rural telemedicine visits from January 2012 to June 2020, using administrative data from Ontario, Canada. We compared the changes in telemedicine use among residents of rural and urban regions of Ontario prior to and during the pandemic.ResultsBefore the pandemic, telemedicine use was steadily low in 2012-2019 for both rural and urban populations but slightly higher overall for rural patients (11 visits per 1000 patients vs 7 visits per 1000 patients in December 2019, P<.001). The rate of telemedicine visits among rural patients significantly increased to 147 visits per 1000 patients in June 2020. A similar but steeper increase (P=.15) was observed among urban patients (220 visits per 1000 urban patients). Telemedicine use increased across all age groups, with the highest rates reported among older adults aged ≥65 years (77 visits per 100 patients in 2020). The proportions of patients with at least 1 telemedicine visit were similar across the adult age groups (n=82,246/290,401, 28.3% for patients aged 18-49 years, n=79,339/290,401, 27.3% for patients aged 50-64 years, and n=80,833/290,401, 27.8% for patients aged 65-79 years), but lower among younger patients <18 years (n=23,699/290,401, 8.2%) and older patients ≥80 years (n=24,284/290,401, 8.4%) in 2020 (P<.001). There were more female users than male users of telemedicine (n=158,643/290,401, 54.6% vs n=131,758/290,401, 45.4%, respectively, in 2020; P<.001). There was a significantly higher proportion of telemedicine users residing in relatively less rural than in more rural regions (n=261,814/290,401, 90.2% vs n=28,587/290,401, 9.8%, respectively, in 2020; P<.001).ConclusionsTelemedicine adoption increased in rural and remote areas during the COVID-19 pandemic, but its use increased in urban and less rural populations. Future studies should investigate the potential barriers to telemedicine use among rural patients and the impact of rural telemedicine on patient health care utilization and outcomes.

Project description:BackgroundThe coronavirus disease 2019 (COVID-19) pandemic is thought to have increased use of virtual care, but population-based studies are lacking. We aimed to assess the uptake of virtual care during the COVID-19 pandemic using comprehensive population-based data from Ontario.MethodsThis was a repeated cross-sectional study design. We used administrative data to evaluate changes in in-person and virtual visits among all residents of Ontario before (2012-2019) and during (January-August 2020) the COVID-19 pandemic. We included all patients who had an ambulatory care visit in Ontario. We excluded claims for patients who were not Ontario residents or had an invalid or missing health card number. We compared monthly or quarterly virtual care use across age groups, neighbourhood income quintiles and chronic disease subgroups. We also examined physician characteristics that may have been associated with virtual care use.ResultsAmong all residents of Ontario (population 14.6 million), virtual care increased from 1.6% of total ambulatory visits in the second quarter of 2019 to 70.6% in the second quarter of 2020. The proportion of physicians who provided 1 or more virtual visits per year increased from 7.0% in the second quarter of 2019 to 85.9% in the second quarter of 2020. The proportion of Ontarians who had a virtual visit increased from 1.3% in 2019 to 29.2% in 2020. Older patients were the highest users of virtual care. The proportion of total virtual visits that were provided to patients residing in rural areas (v. urban areas) declined significantly between 2012 and 2020, reflecting a shift in virtual care to a service increasingly used in urban centres. The rates of virtual care use increased similarly across all conditions and across all income quintiles.InterpretationOur findings show that Ontario's approach to virtual care led to broad adoption across all provider groups, patient age, types of chronic diseases and neighborhood income. These findings have policy implications, including use of virtual care billing codes, for the ongoing use of virtual care during the second wave of the pandemic and beyond.
