Among hospitalized persons under investigation for coronavirus disease 2019 (COVID-19), more repeated severe acute respiratory syndrome coronavirus 2 nucleic acid amplification tests (NAATs) after a negative NAAT were positive from lower than from upper respiratory tract specimens (1.9% vs 1.0%, = .033). Lower respiratory testing should be prioritized among patients displaying respiratory symptoms with moderate-to-high suspicion for COVID-19 after 1 negative upper respiratory NAAT.

Background: Pain catastrophizing, or the interpretation of pain as unbearable or intolerable, can increase pain-related anxiety and severity. High levels of pain catastrophizing have also been linked to substance use, particularly for substances with analgesic properties.
