Prioritizations in Swedish cataract surgery - when resources are limited-Exemplified by the COVID-19 pandemic

To study the prioritization effects of the of COVID-19 pandemic on Swedish cataract surgery using a national healthcare registry with high coverage.

A study from the Swedish National Cataract Register (NCR), involving all patients undergoing cataract surgery in Sweden during 2019-2022 - before, during and after the COVID-19 pandemic.

With the pandemic outbreak, the number of cataract surgeries fell by 22% in 2020 (15 369 procedures), albeit with large regional differences (-43% to +58%). The numbers recovered in 2021, and in 2022, a new top notation was seen (n = 149 952). On a national level, the patients were younger (-0.46 years, p < 0.001), with a larger proportion of less difficult cases (p < 0.001) and the proportion of males was higher (p < 0.001) during the pandemic, but all these variables also differed substantially between different regions and clinics.

A national registry with high coverage can map the consequences of an event disrupting elective surgery in detail. During the COVID-19 pandemic, the impact on Swedish cataract surgery varied largely between different regions, clinics, and healthcare providers, leading to inequality in the availability of surgery. These differences likely owed to variations in healthcare policy approaches in different parts of the country. The present study shows that outcomes at one clinic or region cannot be extrapolated to larger regions under these circumstances. It actualizes the need to aim for a healthcare on equal terms, but it also shows a system that delivers care to many despite difficult times.
