BACKGROUND: Guidelines recommend urgent evaluation for transient monocular vision loss (TMVL) and retinal artery occlusion (RAO), but emergency department (ED) utilisation for these conditions is unknown.
METHODS: We performed a retrospective longitudinal cross-sectional analysis of the Nationwide Emergency Department Sample (2011-2018), a database of all ED visits from a representative 20% sample of US hospital-based EDs. We identified patients aged 40 and older with a primary diagnosis of TMVL or RAO and calculated the weighted number of total visits and admission rate by year. We used joinpoint regression to analyse time trends and logistic regression to measure differences according to demographic characteristics and comorbidities.
RESULTS: There were an estimated 2451 ED visits for TMVL and 2472 for RAO annually in the USA from 2011 to 2018. Approximately 36% of TMVL and 51% of RAO patients were admitted. The admission rate decreased by an average of 4.9% per year for TMVL (95% CI -7.5% to -2.3%) and 2.2% per year for RAO (95% CI -4.1% to -0.4%), but the total number of ED visits did not change significantly over time. Elixhauser Comorbidity Index and hyperlipidaemia were associated with increased odds of hospital admission for both TMVL and RAO. There were also differences in admission rate by insurance payer and hospital region.
CONCLUSION: Of the estimated 48 000 patients with TMVL or RAO annually in the USA, few are evaluated in the ED, and admission rates are less than for transient ischaemic attack or ischaemic stroke and are decreasing over time.
