COVID-19's impact on care practice for alpha-1-antitrypsin deficiency patients

Determining If COPD Self-Management Televisit-Based Interventions Are Evaluated Among and Equitably Effective Across Diverse Patient Populations to Reduce Acute Care Use: A Scoping Review

TOPIC IMPORTANCE

With telemedicine's expansion during the COVID-19 pandemic, it has become critical to evaluate whether patients have equitable access and capabilities to use televisits optimally for improved COPD outcomes such as reduced hospitalizations. This scoping review evaluated whether televisit-based interventions are evaluated and equitably effective in improving health care use outcomes among diverse patient populations with COPD.

REVIEW FINDINGS

Using a systematic search for televisit-based COPD self-management interventions, we found 20 studies for inclusion, all but one of which were published before the COVID-19 pandemic. Most (11/20) were considered good-quality studies. Most studies (19/20) reported age and sex; few provided race (3/20) or income (1/20) data. The most frequently used televisit-based methods were in person plus phone (6/20), video only (6/20), and phone only (4/20). Most studies (12/20) showed a significant reduction in at least one health care use metric; nine studies found hospitalization-related reductions. Effective interventions typically used two methods (eg, in person plus televisits), a video methods, or both.

SUMMARY

Most studies failed to report on participants' race or income, leading to a lack of data on the equity of interventions' effectiveness across diverse patient populations. Multimethod televisit-based interventions, particularly with an in-person component, most commonly were effective; no associations were seen with study quality or size. With the increasing reliance on telemedicine to provide chronic disease care, the lack of data among diverse populations since the COVID-19 pandemic began limits generalizability of these findings for real-world clinical settings. More comprehensive evaluations of televisit-based interventions are needed in the era after the pandemic within and across diverse patient populations.

Impact of the COVID-19 Pandemic on People Living With Rare Diseases and Their Families: Results of a National Survey

BACKGROUND

With more than 103 million cases and 1.1 million deaths, the COVID-19 pandemic has had devastating consequences for the health system and the well-being of the entire US population. The Rare Diseases Clinical Research Network funded by the National Institutes of Health was strategically positioned to study the impact of the pandemic on the large, vulnerable population of people living with rare diseases (RDs).

OBJECTIVE

This study was designed to describe the characteristics of COVID-19 in the RD population, determine whether patient subgroups experienced increased occurrence or severity of infection and whether the pandemic changed RD symptoms and treatment, and understand the broader impact on respondents and their families.

METHODS

US residents who had an RD and were <90 years old completed a web-based survey investigating self-reported COVID-19 infection, pandemic-related changes in RD symptoms and medications, access to care, and psychological impact on self and family. We estimated the incidence of self-reported COVID-19 and compared it with that in the US population; evaluated the frequency of COVID-19 symptoms according to self-reported infection; assessed infection duration, complications and need for hospitalization; assessed the influence of the COVID-19 pandemic on RD symptoms and treatment, and whether the pandemic influenced access to care, special food and nutrition, or demand for professional psychological assistance.

RESULTS

Between May 2, 2020, and December 15, 2020, in total, 3413 individuals completed the survey. Most were female (2212/3413, 64.81%), White (3038/3413, 89.01%), and aged ≥25 years (2646/3413, 77.53%). Overall, 80.6% (2751/3413) did not acquire COVID-19, 2.08% (71/3413) acquired it, and 16.58% (566/3413) did not know. Self-reported cases represented an annual incidence rate of 2.2% (95% CI 1.7%-2.8%). COVID-19 cases were more than twice the expected (71 vs 30.3; P<.001). COVID-19 was associated with specific symptoms (loss of taste: odds ratio [OR] 38.9, 95% CI 22.4-67.6, loss of smell: OR 30.6, 95% CI 17.7-53.1) and multiple symptoms (>9 symptoms vs none: OR 82.5, 95% CI 29-234 and 5-9: OR 44.8, 95% CI 18.7-107). Median symptom duration was 16 (IQR 9-30) days. Hospitalization (7/71, 10%) and ventilator support (4/71, 6%) were uncommon. Respondents who acquired COVID-19 reported increased occurrence and severity of RD symptoms and use or dosage of select medications; those who did not acquire COVID-19 reported decreased occurrence and severity of RD symptoms and use of medications; those who did not know had an intermediate pattern. The pandemic made it difficult to access care, receive treatment, get hospitalized, and caused mood changes for respondents and their families.

CONCLUSIONS

Self-reported COVID-19 was more frequent than expected and was associated with increased prevalence and severity of RD symptoms and greater use of medications. The pandemic negatively affected access to care and caused mood changes in the respondents and family members. Continued surveillance is necessary.

Impact of Coronavirus Disease 2019 and Vaccination Attitudes on Alpha-1 Antitrypsin Deficiency

Background

Individuals with alpha-1 antitrypsin deficiency (AATD)-associated chronic obstructive pulmonary disease (COPD) may be at increased risk of coronavirus disease 2019 (COVID-19) pneumonia since COPD is associated with an increased risk of severe COVID-19 infection.

Research Question

We hypothesized that the AlphaNet disease management program would lower COVID-19 burdens. We evaluated the prevalence of COVID-19 infection, severe COVID-19, interruptions in augmentation therapy, and intention to vaccinate.

Study Design and Methods

Data regarding COVID-19 were collected monthly from March 2020 through February 2022. Responses from 8019 individuals were analyzed to evaluate the prevalence and severity of COVID-19 infections, interruptions in AATD care, and the likelihood of vaccination.

Results

By the end of 2020, 4% of patients reported a positive COVID-19 test. Of those, 35.3% were hospitalized, with 8.6% admitted to the intensive care unit (ICU). By February 2022, the prevalence of COVID-19 infections had increased to 18.6%, with hospitalization rates of 22.1% and ICU admissions at 4.7%. Attitudes about COVID-19 vaccination assessed in December 2020 before the vaccine was widely available suggested 10.3% of patients would definitely not get the vaccine. Notably, 38.2% of those subsequently self-reported receipt of a COVID-19 vaccine.

Interpretation

The prevalence of COVID-19 infections in patients with AATD was lower than the prevalence in the general U.S. population during 2020, although with a higher hospitalization rate. This health-managed population has a high vaccination intent. Those with an initially low vaccination intent changed their minds over time. We interpret these results as showing that most AlphaNet individuals with AATD had success at navigating the COVID-19 pandemic with lower case rates than the general U.S. population.
