Your one-stop shop for all of your COVID-19 related needs, including clinical guidance, maintaining regular primary care practice in the COVID-19 context, social care guidance, local services and more.

Now more than ever it is important for your patients to look after their health and receive care from you as their healthcare provider. It’s essential that patients continue to seek out care that they need.

This tool has been developed to support primary care providers in navigating and providing patient care in a world where COVID-19 is the ‘new normal’, with considerations and recommendations on what’s ‘new’ and what’s ‘changed’ in the delivery of care for patients living with Asthma. While how care is delivered has changed, efforts should be made to ensure that the quality has not. As always, when treating your patients, continue to use your clinical judgement and follow standards of care, best practices, evidence and guidelines.

Key takeaway

There does not appear to be an increased risk of acquisition of COVID-19 among asthma patients, but it is probable that COVID-19 can trigger asthma exacerbations. (CTS, April 7, 2020).

Management

Ensure adherence to regular asthma treatment (CTS, April 7, 2020; The Lung Association, June 2, 2020)

Discuss wearing a mask and address any concerns or anxieties the patient might have.

There is no evidence that wearing a facemask will exacerbate an underlying lung condition (CTS, June 2, 2020). If breathing through a mask causes a patient to feel short of breath, they should remove the mask, and if symptoms do not immediately settle, they should follow their existing strategy for relief of acute symptoms.
If wearing a facemask is not possible despite best efforts, patients should instead avoid or minimize circumstances where physical distancing is not possible.

Putting it into practice

Treatment

It is important for patients with asthma to adhere to regular asthma treatment during the COVID-19 pandemic (CTS, April 7, 2020; The Lung Association, June 2, 2020).

Putting it into practice

The Canadian Thoracic Society (CTS, April 7, 2020) states that:

Inhaled maintenance therapies: Patients with asthma should restart or continue to use their prescribed inhaled maintenance therapy to improve disease control and to reduce the severity of exacerbations.
Corticosteroids: There is no evidence that inhaled corticosteroids increase the risk of acquiring COVID-19 or that they increase the severity of infection. Prednisone may be used to treat severe asthma exacerbations, including those caused by COVID-19 infection. Dosage should be low-to-moderate (≤ 0.5-1 mg/kg per day methylprednisolone or equivalent) and duration should be short (≤ 7 days) for exacerbations suspected to be caused by COVID-19 infection.
Biologics: Biologics should be continued during the COVID-19 pandemic. If biologic therapies are interrupted temporarily, it is suggested to step-up other controller therapies on an individualized basis. Where available, family physicians/primary care nurse practitioners may consider switching patients to self-administration of biologics at home.
Nebulized therapy: Nebulized therapy should be avoided during this pandemic. For patients who are already using nebulizers at home, they should continue to do so until they discuss switching to an alternative with their family physician/primary care nurse practitioner. Alternatives to nebulized therapy include therapy with a metered dose inhaler (MDI) with spacing device, or a dry powder inhaler.

The COVID-19 Resource Centre was developed by the Centre for Effective Practice (CEP) in collaboration with the Department of Family Medicine at McMaster University, the Ontario College of Family Physicians and the Nurse Practitioners’ Association of Ontario using a rapidly modified version of the CEP’s integrated knowledge translation approach.

They are some of several clinical resources developed as part of the Knowledge Translation in Primary Care Initiative. Funded by the Ministry of Health and Long-Term Care, this initiative supports primary care providers with the development of a series of clinical tools and health information resources.
