Retrospective analysis of ophthalmology referrals during the COVID-19 pandemic compared to prepandemic.

OBJECTIVE: This study was conducted to analyse emergency ophthalmology referrals to a Canadian tertiary academic centre during the current coronavirus disease 2019 (COVID-19) pandemic in comparison to prepandemic referrals. DESIGN: This was a retrospective chart review looking at emergency referrals seen by the ophthalmology service between March 18 to April 17, 2020 (representing the COVID-19 period), and March 18 to April 17, 2019 (representing the pre-COVID-19 period). METHODS: Data gathered from referral records included patient demographics, timing and site of referral, and ophthalmic diagnosis. Referrals were categorized as urgent or nonurgent, with urgent indicating the need for ophthalmic assessment within 24 hours. RESULTS: The total number of referrals decreased by 54.2% in the COVID-19 period versus the pre-COVID-19 period. There was a similar bimodal age distribution in both periods, with fewer patients over 65 years of age presenting during the pandemic. Tertiary hospital referrals decreased by 62% in the pandemic period, while nontertiary emergency department referral trends varied and outpatient clinic referrals increased by 16%. Overall, there was a significant shift in the distribution of referral sites (p = 0.04). The proportion of urgent referrals increased by 14% during the pandemic; this was not statistically significant. There was no significant change in the timing of referrals or in the distribution of diagnostic segments. CONCLUSIONS: This study offers insight into the impact of the COVID-19 pandemic on ophthalmology referral patterns in a Canadian context. Moving forward, it helps to guide resource allocation and public education on the importance of seeking necessary eye care.

Local anaesthesia as a standard of care for penetrating keratoplasty?

BACKGROUND/OBJECTIVES: To determine preferences in the use of local anaesthesia (LA) versus general anaesthesia (GA) for penetrating keratoplasty (PK), and to examine the safety of LA for PK. SUBJECTS/METHODS: A retrospective analysis of PKs performed at an ophthalmology department in Canada from 01/01/2008 to 01/01/2020 was conducted to investigate rate of major complications. A questionnaire was also sent out to cornea specialists in the United Kingdom (UK) and Canada to determine trends in anaesthesia use for PK. Data on anaesthesia use in keratoplasty data was also obtained from the National Health Service Blood and Tissue (NHSBT) register. RESULTS: The retrospective study found that 2143 PKs were performed under LA by 4 surgeons. The following complications were revealed: 1 acute anxiety attack with tachycardia, 3 extraocular myotoxicity cases requiring squint surgery, 1 expulsive suprachoroidal haemorrhage and 1 retrobulbar haemorrhage. The survey revealed 92% of cornea specialists in Canada preferred LA to GA. In the UK, 4.5% of specialists preferred LA, with most preferring GA due to suprachoroidal haemorrhage risk. NHSBT data revealed that 86.6% of 6181 PKs performed in UK between 01/04/2015 and 31/03/2020 were done under GA. CONCLUSIONS: LA is preferred for PK in Canada, in contrast to the UK where GA is preferred. Our retrospective study suggests a low incidence of LA-related complications. We suggest that LA should be considered for most cornea transplant techniques, including optical penetrating keratoplasty. Rising worldwide keratoplasty numbers, ageing populations and risks of pandemics (e.g. COVID-19) give more reason for reduced reliance on GA.

Transforming Disruption Into Innovation: A Partnership Between the COVID-19 Medical Student Response Team and the University of British Columbia.

The COVID-19 pandemic caused substantial disruptions in medical education. The University of British Columbia (UBC) MD Undergraduate Program (MDUP) is the sixth-largest medical school in North America. MDUP students and faculty developed a joint response to these disruptions to address the curriculum and public health challenges that the pandemic posed. After clinical activities were suspended in March 2020, third- and fourth-year MDUP students formed a COVID-19 Medical Student Response Team (MSRT) to support frontline physicians, public health agencies, and community members affected by the pandemic. A nimble organizational structure was developed across 4 UBC campuses to ensure a rapid response to meet physician and community needs. Support from the faculty ensured the activities were safe for the public, patients, and students and facilitated the provision of curricular credit for volunteer activities meeting academic criteria. As of June 19, 2020, more than 700 medical students had signed up to participate in 68 projects. The majority of students participated in projects supporting the health care system, including performing contact tracing, staffing public COVID-19 call centers, distributing personal protective equipment, and creating educational multimedia products. Many initiatives have been integrated into the MDUP curriculum as scholarly activities or paraclinical electives for which academic credit is awarded. This was made possible by the inherent flexibility of the MDUP curriculum and a strong existing partnership between students and faculty. Through this process, medical students were able to develop fundamental leadership, advocacy, communication, and collaboration skills, essential competencies for graduating physicians. In developing a transparent, accountable, and inclusive organization, students were able to effectively meet community needs during a crisis and create a sustainable and democratic structure capable of responding to future emergencies. Open dialogue between the MSRT and the faculty allowed for collaborative problem solving and the opportunity to transform disruption into academic innovation.
