A national survey of early treatment seeking behavior among those with incident SARS-CoV-2 infection

Background: Despite effective means to treat SARS-CoV-2 infection, the early treatment seeking behavior of those newly diagnosed with infection is not clear.
Methods: We surveyed users of a national SARS-CoV-2 testing company to assess the frequency and correlates of early treatment seeking behavior for a positive test result.
We recruited adults (18 years or older) who had tested positive for SARS-CoV-2 by PCR at a large clinical laboratory. To be eligible, individuals had to have a positive test result within 7 days of enrollment. Surveys were anonymous and voluntary. We collected data on demographic characteristics, general health care access and utilization, awareness of treatment for COVID-19, treatment seeking behavior, and treatments received. Descriptive statistics and odds ratios (OR) with 95% confidence intervals (95% CI) were calculated on StataSE.
Results: Participants were surveyed from 3-7 January 2022: among the 15,991 who viewed a survey request, 7,647 individuals were eligible and provided responses. The median age of a respondent was 42 years (interquartile range: 32 to 54), 68.9% of respondents were women, and respondents represented 33 different states, districts, and territories. Among respondents, 23.1% reported they had sought treatment or medical advice for their current COVID-19 diagnosis. Of those who were very aware of treatment for COVID-19, 31.0% sought treatment versus 16.7% who were unaware (p-value< 0.001). The odds of treatment seeking behavior were higher for those that were contacted by a medical professional after their diagnosis (OR: 4.57 [95% CI: 3.89 to 5.37]), those with a primary doctor (OR: 2.94 [95% CI: 2.52 to 3.43]), those who self-measured their oxygen saturation (OR: 2.53 [95% CI: 2.25 to 2.84]), and those over 65 years of age (OR: 2.36 [95% CI: 2.02 to 2.76]). There was no difference in those seeking treatment based on heritage, ethnicity, prior COVID-19 diagnosis, state political affiliation, or vaccination status. The odds of seeking treatment were lower among men (OR: 0.88 [95% CI: 0.78 to 0.99]) and those without insurance (OR: 0.62 [95% CI: 0.52 to 0.72]). The most common treatment locations were clinics and most common treatments were Vitamin C, Vitamin D, Zinc, Tylenol, and NSAIDs.
Conclusion: More public outreach is needed to raise awareness of the benefits of treatment for COVID-19. We found that people who were more aware about treatment for COVID-19 were more likely to seek medical advice or therapy. Efforts to increase awareness might increase early treatment for SARS-CoV-2 infection. Increased outreach with treatment facilitation from medical professionals and/or public health staff to those with newly detected SARS-CoV-2 infections, particularly among those at higher-risk of complications, might also be helpful.

COVID-19 continues to cause severe disease, hospitalization, and death. Despite effective means to treat SARS-CoV-2 infection with nirmatrelvir/ritonavir, molnupiravir, monoclonal antibodies, and remdesivir [1−4], the early treatment seeking behavior of those newly diagnosed with infection is not clear. We surveyed users of a national SARS-CoV-2 testing company to assess the frequency and correlates of early treatment seeking behavior for a positive test result.
We recruited adults (18 years or older) who had tested positive for SARS-CoV-2 by PCR at a large clinical laboratory (Curative, San Dimas, CA). To be eligible, individuals had to have a positive test result within 7 days of enrollment. Surveys were anonymous and voluntary. We collected data on demographic characteristics, general health care access and utilization, awareness of treatment for COVID-19, treatment seeking behavior, and treatments received. Questions were developed to be answered in a multiple choice fashion for user ease. Descriptive statistics and odds ratios (OR) with 95% confidence intervals (95% CI) were calculated on StataSE (StataCorp, College Station, TX). Chi-squared tests and linear regression analysis were used to compare categorical variables and continuous variables between groups, respectively. Advarra granted the study IRB exempt (Pro00059961).
Participants were surveyed from 3-7 January 2022: among the 15,991 who viewed a survey request, 7,647 individuals were eligible and provided responses. The median age of a respondent was 42 years (interquartile range: 32 to 54), 68.9% of respondents were women, and respondents represented 33 different states, districts, and territories. Among those surveyed, 66.7% identified as White, 30.6% as Hispanic, 12.1% as Black or African American, 6.2% as Asian, and 1.2% as Pacific Islander or Native American. Most respondents reported they were vaccinated (89.3%).
Among respondents, 23.1% reported they had sought treatment or medical advice for their current COVID-19 diagnosis (Table 1). Of those who were very aware of treatment for COVID-19, 31.0% sought treatment versus 16.7% who were unaware (p-value< 0.001). The odds of treatment seeking behavior were higher for those that were contacted by a medical professional after their diagnosis (OR: 4 There was no difference in those seeking treatment based on heritage, ethnicity, prior COVID-19 diagnosis, state political affiliation, or vaccination status. The odds of seeking treatment were lower among men (OR: 0.88 [95% CI: 0.78 to 0.99]) and those without insurance (OR: 0.62 [95% CI: 0.52 to 0.72]). The most common treatment locations were clinics and most common treatments were Vitamin C, Vitamin D, Zinc, Tylenol, and NSAIDs (Table 2).
Due to the timing of the survey, infection was most likely due to the Omicron variant of SARS-CoV-2, which might be less severe in those with prior immunity [5]. The most commonly used treatments were over-the-counter medications for symptom relief which are not FDA authorized for effective treatment of COVID-19. Few had received therapies known to reduce risk of disease progression like nirmatrelvir/ritonavir, molnupiravir, monoclonal antibodies, and remdesivir [4,6]. There were also continued reports of non-beneficial medication use, i.e., ivermectin and hydroxychloroquine.
Individuals that recovered from COVID-19 before did not seem to have different behavior patterns when compared to those who were naïve to SARS-CoV-2 infection. It is possible that a history of COVID could be reassuring to individuals, therefore there was no change in treatment seeking behavior. Additionally, those with prior infection might have had milder symptoms due to their prior exposure to COVID-19 [7].
The main limitation of this study is that it is subject to response bias. Many of the eligible respondents did not provide survey data, so the results we found may be biased. Also, given that the survey was sent electronically and answered in an electronic format, it may have skewed responses to individuals that have better access to internet or better electronic literacy. Due to the timing of this survey, some medicines that have been found to be effective for COVID-19 may have not been available or medically rationed due to supply chain problems.
More public outreach is needed to raise awareness of the benefits of effective treatment for COVID-19 with FDA authorized treatments like nirmatrelvir/ritonavir, molnupiravir, monoclonal antibodies, and remdesivir, and limit the use of medications that are not effective for COVID-19. We found that people who were more aware about treatment for COVID-19 were more likely to seek medical advice or therapy, however the majority of individuals that had sought medical advice or therapy did not ultimately use effective treatments for COVID-19. Efforts to increase awareness of effective treatments for COVID-19 and their indications might increase the use of early effective treatment for SARS-CoV-2 infection, while reducing the use of medications that do not provide benefit. Additionally, those who were contacted by a health professional were more likely to seek treatment or medical advice for COVID-19. Increased outreach with treatment facilitation from medical professionals and/or public health staff to those with newly detected SARS-CoV-2 infections, particularly among those at higher-risk of complications, might also be helpful to educate individuals about effective medications and noneffective medications for COVID-19.
