Study Notes

Disparities in Isolation During COVID-19

Lower-income communities struggled to physically isolate during COVID-19 due to limited work-from-home options.
Areas in New York with predominantly Black/African American and Hispanic populations faced higher COVID-19 positivity rates and fewer healthcare resources, such as licensed hospital beds and ICU beds, compared to predominantly White areas.

Disparities in Access to COVID-19 Treatments

Racial and ethnic disparities in the administration of anti-SARS-CoV-2 monoclonal antibodies (mAbs) were evident, with Black/African American patients being 22.4% less likely to receive treatment than White patients.
Other racial groups, including Asians and those classified as other races, similarly experienced reduced access to mAbs.
From April to July 2022, Black/African American patients received ritonavir-boosted nirmatrelvir 35.8% less frequently than White patients, with Hispanic patients receiving it 29.9% less frequently.
Despite more dispensing sites in socially vulnerable neighborhoods, COVID-19 oral antivirals were prescribed less frequently in these areas.
Among veterans hospitalized for COVID-19, Black veterans had lower odds of receiving key treatments, including systemic steroids and remdesivir.

Impact of Variants and Classification Confusion

CDC introduced a new variant designation category in September 2021 and has monitored variants impacting approved medical countermeasures.
The Omicron variant, designated a variant of concern in November 2021, quickly became dominant worldwide, with subvariants emerging in early to mid-2022 (e.g., BA.1, BA.2, BA.4, BA.5).
Newer Omicron subvariants exhibit higher transmissibility and resistance to previously authorized anti-SARS-CoV-2 mAbs.
Research on variant implications for transmission, disease progression, and therapeutic efficacy is rapidly evolving, necessitating updates from sources like the CDC and WHO.

Pulse Oximetry Limitations

Pulse oximetry use surged during the pandemic, but its accuracy can be compromised by factors like skin pigmentation and circulation issues.
Inaccurate readings may delay recognition of hypoxemia, especially among patients with darker skin, leading to worse health outcomes.
A study showed 24% of patients misidentified as ineligible for treatment due to overestimations of O2 saturation, with Black patients disproportionately affected (55%).

Asymptomatic and Mild COVID-19 Cases

Asymptomatic COVID-19 infections can occur, but the proportion remains uncertain; some asymptomatic patients showed COVID-19 pneumonia on imaging.
Mild illness symptoms include fever, cough, and loss of taste, without significant respiratory distress; these patients typically manage at home.
Higher-risk patients, including those aged 50+, patients with comorbidities, or unvaccinated individuals, may require antiviral treatment.

Moderate to Severe COVID-19 Illness

Moderate illness is characterized by respiratory issues and SpO2 levels of ≥94% at sea level; patients require close monitoring.
Severe illness occurs with SpO2 <90%, indicating possible rapid deterioration; these patients should receive oxygen therapy and hospitalization for treatment.
