Abstract: Objectives: To evaluate neurologists and other clinicians’ contributions to U.S. ALS diagnostic timelines. Background: Over the past two decades, the average time to ALS diagnosis in the U.S. has remained unchanged at 12 months. ALS patients see 3-4 clinicians prior to referral to an ALS specialist for diagnosis confirmation and/or treatment initiation. There is an urgent need to identify where delays occur, so that targeted clinician awareness may be raised about early suspicion and referrals. Methods: Review of Medicare claims database for health care utilization patterns by ALS beneficiaries during diagnostic journey. Survey of typical clinic wait times for new consultations reported by 75-78 ALS Certified Treatment Centers of Excellence (2019-2021). Results: During 2011-2021, 78,520 Medicare beneficiaries were diagnosed with ALS (T0). The mean (median) timelines between first neurologist ambulatory visit and T0, is 16.5 (11.0) months; mean ± SD for ALS/neuromuscular providers being 9.6 ± 12.6 months versus 16.7 ± 17.5 months for non-neuromuscular neurologists. During the 12-months preceding T0, an ALS patient undergoes median(max) 1.5(4.0) brain-MRIs, 1.6(6.0) spine-MRIs, and 1.3(4.0) electromyography studies. Greater than 75% of ALS centers consistently report ≤ 4 week wait times for new ALS consults. This study introduces “thinkALS,” an easy-to-use clinical diagnostic and referral guide for non-ALS neurologists to tackle this challenge. Conclusions: This study is the first to provide metrics on how non-neuromuscular/ALS specialists contribute to ALS diagnostic timelines in the U.S.
