Study design Retrospective comparative review.Objective The aim of this study was to determine the short-term impact of the COVID-19 pandemic on the demographic and clinical profile of new idiopathic scoliosis (IS) patients, with a particular focus on treatment and late referral. Summary of background dataThe COVID-19 pandemic has limited health-care services and public access and, as a result, the diagnosis and management of non-COVID-19 health conditions have been compromised. Delayed diagnosis of IS may limit conservative treatment options and subsequently, increase a patient's risk of requiring surgical intervention. Methods The volume of spine referrals received and new IS clinic visits were compared between March 15-October 15, 2019 and the same period in 2020. A chart and radiographic review detailed the patient profile at initial presentation. Descriptive statistics and comparative analyses examined the referral source, curve magnitude, skeletal maturity, and prescribed treatment. Late referrals were those with a curve magnitude ≥ 50°, or > 40° and Risser 2 or less. Results During the 2020 study period, the referral volume decreased 76% and clinic visits 55%. The 2019 cohort was similar in age (13.7 ± 2.1 years vs 13.3 ± 2.3 years, p = 0.08), Risser score distribution (p = 0.32), menarchal status (0.07), and curve magnitude (37.1° ± 3.8° vs 39.0° ± 16.0°, p = 0.22). During the pandemic, there was an increased proportion of referrals made by pediatricians (41 to 54%, p = 0.01). The proportion of brace prescriptions increased from 30 to 42% (p = 0.01). The proportion of surgical bookings and late referrals were increased but did not reach significance. Conclusion Despite no significant increase in the magnitude of the curve at initial presentation or the proportion of late referrals, there was a marked decrease in referral volume, over the first 7 months of the COVID-19 pandemic. This suggests that the majority of expected new IS patients remain undiagnosed. A future increase in late referrals should be anticipated. Level of evidence III.

Purpose Primary care physicians rely on radiology reports to confirm a scoliosis diagnosis and inform the need for spine specialist referral. In turn, spine specialists use these reports for triage decisions and planning of care. The objectives were to determine (1) the adequacy of index images to inform treatment decisions at the initial consultation and (2) the utility of index radiology reports for appropriate triage decisions. Methods A retrospective chart review was conducted including all idiopathic scoliosis patients seen for initial consultation, aged three to 18 years, between January 1 and April 30, 2021. A score out of five was generated based on the adequacy of index images to provide accurate Cobb angle measurements and determine skeletal maturity. Index images were considered inadequate if repeat imaging was necessary. Index radiology reports, associated imaging, and new imaging, if obtained at the initial consultation, were compared. Results Of the 94 patients reviewed, 79% (n = 74) required repeat imaging at the initial consultation, of which 74% (n = 55) were due to insufficient quality and/or limited field of view. Of index images available for review at the initial consult (n = 80), 41.2% scored five out of five, and 32.5% scored two or below. Comparing index radiology reports to initial visit evaluation with ≤ 60 days between imaging (n = 49), discrepancies in Cobb angle were found in 24.5% (95% CI 14.6, 38.1) of patients. The Risser stage was reported in 14% of index radiology reports. Conclusion Although pre-referral pediatric spine radiographs serve a diagnostic purpose, most are inadequate for comprehensive idiopathic scoliosis evaluation. Level of evidence III.
