Updates on COVID-19 guidance for sleep medicine
Background
Well into its second year, the worldwide COVID-19 pandemic continues to pose substantial challenges for health care access and delivery. Regulatory agencies such as the Centers for Disease Control (CDC) do not currently have guidance related to COVID-19 specific to sleep centers and laboratories. In March 2020, within days of the World Health Organization pandemic declaration, the American Academy of Sleep Medicine (AASM) posted detailed guidance on mitigation strategies for sleep medicine practices (COVID-19 Resources).
This initial guidance has been previously reported in this publication (Sullivan S, Gurubhagavatula I. CHEST Physician 2020 May 8), and the guidance has been periodically updated during the pandemic. It was restructured in mid-2020 to include sections summarizing CDC recommendations germane for sleep practices; additional sleep medicine-specific guidance from the AASM COVID-19 Task Force (TF); and a frequently asked questions (FAQ) section. The last major update from the task force occurred on Jan. 18, 2021, though subsequent posts – especially related to recent CDC changes in masking guidelines – were made in May 2021. The purpose of this article is to summarize these updates and to call attention to areas of ongoing interest to sleep medicine. Notably, the AASM Task Force guidance is nonbinding and offered as a framework for considering best practices in this evolving situation, acknowledging the importance of weighing local factors, conditions, and regulations, as well as the interests of and risks to the patient, staff, and providers.
Key updates
Data on exposure and transmission risks specific to sleep medicine
Measures for reducing viral transmission have been central to managing the spread of the virus in clinical settings. In its last major update, the AASM TF noted that no known outbreaks of COVID-19 related to sleep center exposure have been reported. A perspective and data published in the Journal of the American Medical Association concluded that hospital transmission of the virus “in the setting of universal masking is likely rare, even during periods of high community prevalence.” It also concluded that hospital-based outbreaks are more likely to occur in small workrooms and during mealtime when staff are less adherent to masking and physical distancing (Richterman A, et al. JAMA. 2020;324[21]:2155-6). The TF elaborated on considerations to reduce transmission, which include not just telework and foundational infection control practices, but also broader workplace considerations such as optimizing ventilation, taking advantage of outdoor spaces (e.g., for breaks and eating), scheduling to reduce interactions between personnel from different teams, minimizing contact in meeting/break rooms, removing tables and chairs from lounge areas, and following CDC guidance for effective facility operations.
Vaccination
In the January update, the AASM COVID-19 TF stated that, “sleep facility leaders should encourage staff and patients to be vaccinated in accordance with CDC guidance.” The role of the sleep medicine community in encouraging healthy sleep habits before and after vaccination was emphasized, pointing to evidence linking sleep and immunity, specifically between sleep duration and vaccination response (Healthy sleep and immune response to COVID-19 vaccination. 2021 Jan.).
In an FAQ update from March 26, 2021, considering whether continued COVID-19 testing was needed following full vaccination, the AASM advised testing prior to potential aerosol-generating procedures should be made on the basis of a risk-benefit assessment by the sleep clinician. Several considerations were highlighted, including recent COVID-19 infection, vaccination status of contacts, local prevalence of newer variants, and whether individuals are receiving positive airway pressure therapy. The TF focused on the vigilance for residents and staff in long-term care facilities, which have been associated with a number of outbreaks.
Masking in the context of the COVID-19 vaccine
The most significant change in recommendations is the recent relaxation of masking guidance by the CDC in the setting of the approval and distribution of COVID-19 vaccinations. In May, the CDC stated that fully vaccinated individuals can resume activities without masking or physically distancing except in scenarios of travel and where required by laws, regulations, and local businesses, due to the efficacy of the vaccines, increasing evidence of reduced asymptomatic carriage and transmission after vaccination, and anticipated increased uptake of vaccination. However, the CDC also noted that these updates did not apply to health care facilities, where the recommendation remains that patients and visitors should continue to mask throughout their stay. Additionally, fully vaccinated health care workers should continue to practice infection control measures while working with patients. On May 14, the AASM TF provided a detailed FAQ acknowledging the CDC’s new guidance, emphasizing that masking guidance in health care facilities remains unchanged, and encouraging individuals to follow CDC guidance regarding vaccination, noting that emergence of newer variants continues to be monitored, and existing vaccines still appear to induce neutralizing antibodies even if to a somewhat lower degree. The situation for pediatric sleep centers has been highlighted in particular because the potential risk posed by newer variants to children remains under investigation, and children under age 12 are not approved for vaccination.
Important caveats to discussions around vaccination status are the lack of a centralized method to identify vaccinated individuals, the unknown duration of immunity, and reports of the use of fake vaccine cards. At this time, in health care settings, vaccination status should not exempt mask usage for any individual.
Sleep medicine care for those with COVID-19
Regarding the duration of isolation and precautions for adults with COVID-19, the TF highlighted the CDC’s symptom-based strategy, rather than test-based strategy, for ending isolation of these patients, availing them of sleep medicine services in person.
In line with the CDC guidance, this approach indicates that scheduling in-person care such as polysomnography for a COVID-19–positive patient may be appropriate at least 10 days after symptom onset (or after a positive test if the patient never developed symptoms); or at least 20 days after symptom onset if the illness was severe; or if at least 90 days have elapsed since symptom onset, consider preappointment COVID-19 screening. In the context of immunocompromised individuals, involvement from infectious disease specialists may be needed to help guide decisions.
Patient communications
For many, a repercussion of the pandemic has been delaying care or avoiding addressing medical issues, including sleep disorders. The AASM encouraged practices to consider communicating with patients that delaying needed care can increase health risks; COVID-19 transmission to patients in health care settings has been low; effective safety procedures are in place; and whether remote/telehealth services are available.
Disparities in care
In addition to the specific guidance above, there are ongoing concerns regarding disparities in care resulting from a variety of sources and becoming more evident during the pandemic. Complex factors, ranging from economic, geographic, contextual, occupational, and others contribute to disparities that health care systems – and sleep medicine - have not been able to adequately address (Jackson CL and Johnson DA. J Clin Sleep Med. 16[8]:1401-2). More specific differences may include Internet access, reduced access due to socioeconomic barriers, transportation limitations, medical mistrust, and membership in a medically vulnerable group such as children, the elderly, and those with high acuity needs. For example, in pediatric patients there exist few evidence-based alternatives and guidelines to in-lab testing and care, which may have negatively impacted access to needed sleep medicine services (Sullivan S et al. J Clin Sleep Med. 2021 Mar 1;17[3]:361-2).
Economics in the COVID-19 pandemic
The economic effects of COVID-19 on medical institutions and in sleep medicine is a story that continues to unfold. Reductions in patient visits and elective procedures, infection control measures limiting capacity, increased costs to maintain such measures, and variability of responses by payer and region are just a few of the issues. The Centers for Medicare & Medicaid Services has employed waivers to increased flexibility and promote safe and effective care including the use of telemedicine during the public health emergency, but the future of these waivers remains uncertain. Alarmingly, a sizeable portion of sleep practices reported financial solvency concerns related to the pandemic (Ramar K. J Clin Sleep Med. 2020;16[11]:1939-42).
Conclusion
As the COVID-19 pandemic and related public health guidance continues to evolve, sleep medicine practices continue to adapt. Vaccination, new variants, changes in mask guidance, new outbreaks around the globe, financial and staffing uncertainties, as well as addressing disparities in care and outcomes that may be augmented by the pandemic remain salient areas of ongoing development.
