Recovery of outpatient imaging utilization during the first wave of the COVID-19 pandemic

Abstract

Objective During the COVID-19 pandemic, Radiology practices experienced marked reductions in outpatient imaging volumes. Our purpose was to evaluate the timing, rate, and degree of recovery of outpatient imaging during the first wave of the pandemic. We also sought to ascertain the relationship of outpatient imaging recovery to the incidence of COVID-19 cases. Methods Retrospective study of outpatient imaging volumes in a large healthcare system was performed from January 1, 2019-August 25, 2020. Dataset was split to compare Pre-COVID (weeks 1–9), Peak-COVID (weeks 10–15) and Recovery-COVID (weeks 16–34) periods. Chi-square and Independent-samples t -tests compared weekly outpatient imaging volumes in 2020 and 2019. Regression analyses assessed the rate of decline and recovery in Peak-COVID and Recovery-COVID periods, respectively. Results Total outpatient imaging volume in 2020 (weeks 1–34) was 327,738 exams, compared to 440,314 in 2019. The 2020 mean weekly imaging volumes were significantly decreased in Peak-COVID ( p = 0.0148) and Recovery-COVID ( p = 0.0003) periods. Mean weekly decline rate was −2580 exams/week and recovery rate was +617 exams/week. The 2020 Post-COVID (weeks 10–34) period had an average decrease of 36.5% (4813.4/13,178.6) imaging exams/week and total estimated decrease of 120,335 exams. Significant inverse correlation (−0.8338, p < 0.0001) was seen between positive-tested COVID-19 cases and imaging utilization with 1-week lag during Post-COVID (weeks 10–34) period. Conclusion Recovery of outpatient imaging volume during the first wave of COVID-19 pandemic showed a gradual return to pre-pandemic levels over the course of 3–4 months. The rate of imaging utilization was inversely associated with new positive-tested COVID-19 cases with a 1-week lag.

Lung cancer recovery focus post pandemic: an income-deprived area paradigm

“…21 Naidich et al reported a decrease in the volume of outpatient imaging in 2020 (327,738 examinations) compared with 2019 (440,314 examinations). 22 Unfortunately, because of inherent limitations of the study acknowledged by the authors, specific details categorised by individual imaging modalities were not ascertained. Despite the aforementioned challenges in outpatient service availability, national healthcare organisations strived to maintain cancer diagnostic services at an optimal level right from the start of the pandemic.…”

A Global Review of the Impacts of the Coronavirus (COVID-19) Pandemic on Radiology Practice, Finances, and Operations

“…Outpatient imaging centers also witnessed a decrease in overall imaging volumes. A retrospective analysis of a large integrated healthcare system in the New York City metropolitan region noted a significant decrease in imaging volumes in 2020 compared with 2019 [15]. From 1 January 2020 to 1 March 2020, imaging volumes increased by 7.6%; from 2 March 2020 to 12 April 2020, volumes decreased by 56.6%; and from 13 April 2020 to 23 August 2020, volumes decreased by 30.1% (Figure 2) [15].…”

At an outpatient center at a pediatric hospital in London, there was a decrease in the overall volume from 67,806 records in the pre-COVID-19 period to 48,250 in the COVID-19 period [16].…”
