“…Increased risk of morbidity can be attributed to the immunosuppressive mechanism of action (i.e., with steroids and opioid analgesics) and the respiratory depressive mechanism of action (i.e., with opioid analgesics) ( 89 ). Within this population, comorbid conditions such as lung disease (e.g., asthma, chronic obstructive pulmonary disease, pulmonary fibrosis, smoking), obesity (i.e., BMI >30), heart disease (i.e., coronary artery disease, cardiomyopathies, heart failure), diabetes (i.e., Type I and Type II), an immunocompromised state (e.g., genetic immunodeficiencies, cancer, HIV, cystic fibrosis), or being of older age further increase risk to complications and comorbidity from COVID-19 infection ( 9 , 82 , 85 , 98 , 99 ). One study found that compared to controls, patients with chronic pain on LTOT infected with COVID-19 were at increased risk of visiting the emergency room (RR 2.04), being hospitalized, (RR 2.91), requiring intensive care, mechanical ventilation, vasopressor support, and dying within 30 days ( 100 ).…”
