Chronic condition optimization

Chronic conditions like asthma, COPD, and heart failure often worsen during respiratory season. Proactive management—including timely assessment, individualized action plans and appropriate education for people living with these conditions— can help reduce complications, improve outcomes and support stability during high-risk periods. 

Jump to:

Asthma and COPD

Key messages1–5

  • Minimize exposure to known triggers and optimize daily therapy.
  • Encourage vaccination and good hygiene to prevent respiratory infections.
  • Support self-management with a personalized action plan and ensure medication readiness.

COPD and asthma are chronic respiratory diseases that can worsen during respiratory season due to cold air, viral infections and other environmental triggers.

Both conditions are associated with significant morbidity during respiratory season, but with proper management, most exacerbations are preventable.

Risk stratification

COPD5,8–10
  • The risk of acute exacerbation can be assessed by:
    • History of past acute exacerbations of COPD (i.e., timing, frequency, severity and hospitalizations).
    • Severe and worsening airflow obstruction (based on spirometry results).
    • Presence of chronic bronchitis.
  • Low risk of exacerbation:  ≤1 moderate exacerbation in the past year and did not require ER visit or hospitalization.
  • High risk of exacerbation:  ≥ 2 moderate or ≥1 severe exacerbation in the last year, requiring hospital admission or ED visit.
Asthma 4,6
  • Mild exacerbation: an increase in asthma symptoms from baseline that does not require systemic steroids, an emergency department visit, or a hospitalization. Differentiating this from chronic poorly controlled asthma may only occur retrospectively.
  • Severe exacerbation: an exacerbation requiring any of the following:
    • Systemic steroids
    • Emergency department visit
    • Hospitalization
  • Higher risk of exacerbation:
    • History of severe exacerbation requiring systemic steroids, ED visit and/or hospitalization
    • Poorly controlled asthma
    • SABA overuse (>2 inhalers/year)
    • Current smoker or vape use

Management optimization for respiratory season

Annual review & risk assessment4,6,11,12
  • Conduct an annual assessment (or more frequent if control is poor or after a recent exacerbation) to prepare for respiratory season:
    • Evaluate symptom control, lung function (spirometry as needed) and history of exacerbations.
    • Review medication adherence, inhaler technique and trigger exposures.
    • Identify comorbidities impacting control (e.g., GERD, OSA, depression).
    • Identify impact of social determinants on accessing supports (e.g., education, employment, housing, income, geographic location, transportation, access to care).
Prevent respiratory infections1,3,5,12
  • Immunizations:
    • Annual influenza (OHIP covered)
    • SARS-CoV-2 (OHIP covered)
    • Pneumococcal – consult current recommendations
    • RSV prevention product (OHIP covered for high-risk individuals 60+ and may be purchased for others 60+)
    • TD (booster) – every 10 years (COPD-specific)
    • Shingles (OHIP covered for those between 65-70 years old) (COPD-specific)
    • See seasonal and respiratory immunizations section for more information.
  • Hygiene and exposure reduction:
    • Handwashing and hand sanitizers
    • Avoid face touching
    • Avoid close contact with sick individuals
    • Clean and disinfect surfaces (caution around cleaning agents that can trigger asthma symptoms)
    • Masking in crowded indoor spaces; encourage in cold, windy or high-pollen conditions to help manage allergies.
  • Encourage smoking cessation.
  • Refer to pulmonary rehabilitation if indicated for individuals living with COPD with high symptom burden and risk of exacerbation. See the Lung Health foundation virtual Fitness for Breath classes and exercise videos for more information.
Manage triggers
  • Ensure individuals are prepared and understand common seasonal triggers and environmental control strategies.
Season
Triggers
Strategies

Summer12–16 

  • Environmental triggers: pollen, pet dander, dust mites, mould, smog, humidity 
  • Heat 
  • Smoke: cigarette, cigar, fireplace, wood burning stove or campfire 
  • Overexertion 
  • Check the Pollen Count and local Air Quality Health Index before going outside. Discuss what these numbers mean and how they can make symptoms worse.
  • Schedule physical activity during cooler parts of the day (e.g., morning or evening) and indoors when possible. 
  • Avoid scented products and smoke. 
  • Take breaks when overexerted. 
  • Stay hydrated.
  • Use AC and keep windows closed to minimize exposure to allergens. For more information for OW and ODSP individuals see: https://link.cep.health/sphtml25

Respiratory season1,3,14,15

  • Environmental triggers: cold air (wear mask/scarf), viral infections (see prevent respiratory infections section).
  • Holiday-specific exposures: real trees may carry mould or dust.
  • Allergen and irritant reduction. 
  • Consider Air Quality Health Index before going outside
  • Rinse trees or opt for artificial trees. Clean stored decorations before use. 
  • Improve air filtration (provide recommendations), avoid scented products and smoke, minimize dust/mould. 
  • Ensure individuals are up to date with immunizations. See prevent respiratory infections for more information. 

Self-management and action plans5-7,11,12

Provide/refresh individualized action plans, including strategies for control (e.g., adherence, environmental considerations, trigger management), when to seek urgent care (worsening symptoms), medication management/adjustments, etc. Hospitalization may act as a natural trigger to initiate discussions with patients and their families on advanced care planning. 

Ensure medication readiness (30-day supply), and correct use of inhalers.

Encourage individuals to carry relievers at all times (e.g., at home and at work) and regularly check dose counter.

Referrals

Consider referral to specialized care for:4,6,7,17

Specialized care may include respirologists, allergists, Certified Respiratory Educator (CRE), Certified Asthma Educator (CAE) or other trained professionals.6,7

Asthma

COPD

Heart failure

Key messages

  • Support self-management in different seasons with a personalized action plan.
  • Support management of any comorbidities that may be impacted by seasonal changes, such as COPD.
  • Encourage Immunization as part of seasonal activities in the person’s individualized care plan.

Heart Failure is a clinical condition where the heart is unable to pump enough blood to meet the demands of the body. The condition is complex, progressive and ultimately fatal. Heart Failure is often found alongside other conditions, with 37% of Ontarians experiencing four or more co-occurring chronic conditions. Seasonal weather such as extreme heat, may impact people with cardiovascular disease such as heart failure. While there is still more research needed on the ways in which the heat impacts cardiovascular disease and to what extent, it is important to consider this risk to cardiovascular health.18,19

Symptoms and Severity

Heart Failure’s hallmark symptoms include shortness of breath, fatigue and ankle swelling. There are different categories of people living with Heart Failure which include18,20,21:

The NYHA classification also describes degrees of symptom severity among people living with Heart Failure (PWHF). For more information, see CEP’s Heart Failure tool.

Seasonal preparedness for HF patients12,18

Review care plans
  • Review a person with Heart Failure’s at least every 6 months.
  • Consider timing follow-up appointments just before high-risk times of the year.
  • Consider the way seasonal changes may impact management of their condition and ensure the PWHF and their care partners are knowledgeable about seasonal changes to their care plan.
Prevent exacerbating illnesses
  • Relevant immunizations available in Ontario include:
    • Annual influenza (OHIP covered)
    • SARS-CoV-2 (OHIP covered)
    • Pneumococcal – consult current recommendations
    • RSV prevention product (OHIP covered for high-risk individuals 60+ and may be purchased for others 60+)
    • Shingrix (OHIP covered for seniors 65-70 who have not had a Zostavax® II vaccine) 
Be aware of worsening heart failure
  • Ensure the PWHF is aware of warning signs of worsening heart failure, has a plan for monitoring their symptoms and knows when to take action.
  • When gradual, worsening symptoms are reported, they should be assessed by a clinician and have their medications adjusted (as needed) within 48 hours.
  • For information on coordination of care and referrals see CEP’s Heart Failure tool or seek support from the Best Care program.
Season
Triggers
Strategies

Summer12,18,19,22

  • Heat and increased exertion (e.g., outdoor activities).
  • Dehydration, electrolyte imbalance, and related medication effects. 
  • Increased sodium intake (e.g., summer BBQs, etc.)  
  • Seasonal exacerbation of comorbid conditions.
  • Discuss safe exercise practices and if modifications need to be made during a heat wave. If unsure about safely meeting the physical activity goals, consider consulting a physiotherapist or kinesiologist. 
  • Counsel the person with heart failure about appropriate hydration during hotter than usual times. Be aware that the evidence base to support fluid restriction is limited, and severely limiting intake may have adverse consequences.
  • Consider any changes needed to prescribed diuretic medication.
  • Encourage the PWHF to monitor weight and symptoms daily to detect early signs of worsening heart failure. 
  • Monitor the individual’s dry weight and volume status. 
  • Counsel on appropriate diet and sodium intake. 
  • Discuss and share resources on self-management strategies for the season.
  • Discuss management of co-occurring conditions, such as COPD in summer.

Winter12,18,23,24

  • Cold weather and increased exertion (e.g., snow removal, walking through heavy snow).
  • Reduced physical activity.  
  • Seasonal illnesses, such as respiratory viruses (possible increased risk of worsening heart failure).  
  • Risk of weather impacts, social isolation and travel considerations. 
  • Increased sodium intake (holiday events, etc.).  
  • Seasonal exacerbation of comorbid conditions.
  • Advise keeping warm and wearing appropriate layers of clothing.
  • Discuss safe exercise practices and if modifications need to be made during cold weather. If unsure about safely meeting the physical activity goals, consider consulting a physiotherapist or kinesiologist. 
  • Encourage the PWHF to obtain annual immunizations.
  • Encourage the PWHF to monitor weight and symptoms daily to detect early signs of worsening heart failure.  
  • Encourage the PWHF to maintain a supply of their prescribed medication in case of winter weather and difficulty with travel. 
  • Counsel on appropriate diet and sodium intake.  
  • Discuss and share resources on self-management strategies for the season.
  • Discuss management of co-occurring conditions such as COPD in winter.

Patient resources

Practice management during respiratory season New

This section shares strategies to optimize managing your practice, helping streamline workflows and improve efficiency during the busy fall and winter seasons. It draws on ideas, and resources from various primary care practice models across Ontario. You are encouraged to select and adapt strategies that best fit your context. 

Jump to:

 Planning and proactive strategies 

Proactive patient outreach12,25
  • Encourage seasonal immunizations for all eligible patients. Use multiple channels to maximize engagement. 
    • Clinic website, email campaigns and social media posts that include a booking link or front-desk contact details. 
    • Clinic voicemail message with reminders about seasonal immunizations. 
    • Signage displayed in waiting room as a seasonal reminder. 
    • Recall reminders within EMR to identify eligible patients and prompt outreach activities. 
    • Printed letters sent by mail or direct telephone calls to patients without email access, especially older adults. 
  • Identify high-risk patients for whom seasonal vaccines are recommended, recognizing that eligibility and risk groups vary by vaccine (e.g., age 5 and under, older adults, comorbidities, chronic diseases such as COPD and asthma). 
  • Reach out to high-risk patients with seasonal vaccine recommendations, information on accessing testing and antiviral options.
  • Consider hosting a dedicated ‘Vaccine Day’ to administer the flu shot and other recommended respiratory illnesses vaccines. 
  • Direct patients to convenient vaccination sites, including community pharmacies, as needed.
Patient communication and education12
  • Share educational messages and resources to help patients make informed decisions (e.g., when to seek in-person care vs self-manage symptoms). 
Infection prevention and control (IPAC)12,25,26
  • Plan and review IPAC procedures for your office. 
  • Maintain adequate PPE inventory and order via the PPE Supply Portal as needed. 
  • Consider continuous/universal masking protocols. See OCFP’s “Reminder to wear mask” printable sign. 
    • If you are not implementing continuous/universal masking, make masks available for symptomatic patients (fever, cough, cold, runny nose) and their caregivers to minimize exposure and reduce the risk of transmission during outbreaks like measles. 
  • Consider installing hard surface partitions, such as glass or plexiglass, in the office (e.g., front desk). Physical barriers should be cleaned and disinfected regularly and when visibly dirty. 
  • If feasible, designate separate waiting areas for symptomatic patients. Use rooms that are easy to clean and sanitize regularly (e.g., remove high-touch items such as magazines and toys). 

Effective teamwork and workflow strategies

 Teamwork and coordination12,27-31 
  • If feasible, ensure nurses are integrated into vaccination planning and delivery. For example, nurses played a key role in supporting their teams during the COVID-19 pandemic. These same roles are also critical during respiratory illness season. See contributions for ideas.
  • Consider implementing instant messaging tools to facilitate communication with staff.
  • Hold regular clinical and staff meetings to share learnings from webinars, review workflows and discuss challenges.
  • Consider employing the following strategies to involve other team members in vaccination efforts. See table.
  • If delegating controlled acts in your practice, consider OMA’s delegation checklist to ensure you have met CPSO’s standards and confirm that all staff are trained.

Strategy

Practical application

Engage nurses and pharmacists as educators and administrators 

Leverage trusted relationships to provide vaccine education, address hesitancy and administer seasonal vaccines. 

Target outreach efforts 

Assign nurses or allied staff (e.g., social workers) to reach high-risk or underserved populations through reminder calls, community clinics or home visits. 

Embed vaccine promotion within care 

Incorporate seasonal immunization discussions into routine visits for chronic disease management, wellness checks and follow-ups. 

Where possible, integrate team-based planning 

Involve social workers, pharmacists, administrative staff and allied health professionals in scheduling, coordinating patient communications and information documentation. 

Managing patient access12
  • Encourage patients to see other clinicians in the same clinic if their regular clinician is unavailable. 
  • Schedule symptomatic patients at the end of the day to minimize exposure. 
  • If feasible:
    • Have multiple staff members answer incoming calls to improve responsiveness. 
    • Offer expanded weekday evening and weekend hours to increase accessibility when demand is high. 
    • Schedule overlapping appointments to maximize efficiency. 
    • Reserve 30 minutes daily for same-day appointments, prioritizing patients with respiratory concerns and with flexibility to increase this when demand is high. 
  • Consult OMA’s scheduling tips to help improve scheduling efficiency. 
Referrals and transitions in care12
Optimizing workflows12
  • Use public health disease surveillance data to help inform clinical identification of illnesses.
  • Train front office staff to screen calls for priority, severity, appointment type (in-person vs virtual) and timing (e.g., end of day for symptomatic patients). 
  • Use direct EMR-based email communication (e.g., sending requisitions) to patients, without adding to staff workload. 
Documentation and EMR efficiency12 
  • Remind patients to request that labs, specialists and other external providers (e.g., pharmacists) copy your practice on test results and visit notes to ensure complete and accurate documentation. 
  • Consider using templated notes to improve efficiency. For those interested, AI Scribes may be a helpful option. 
  • Ask patients to keep their immunizations records up to date and record vaccinations in the EMR immunizations section.

Immunization tracking options for patients:

Seasonal and respiratory immunizations New

Maintaining the cold chain—from manufacturer to administration—is essential as breaks (temperature excursions) can cause irreversible potency loss.48 

Key practices:48,49

  • Store refrigerated vaccines at +2°C to +8°C; frozen vaccines at –15°C or colder, or as specified by product monograph (do not refreeze thawed vaccines). 
  • Keep vaccines in original packaging to prevent light/physical damage. 
  • Monitor and record storage/transport temperatures. 
  • Do not use expired or mishandled doses. 
  • Transport with insulated containers and temperature monitoring. 
  • Dispose of vaccines according to jurisdictional standards.  

 

 

Vaccine confidence and equitable access

Jump to:

Vaccine hesitancy12,27,31,50,51

Addressing hesitancy requires individualized and community-based approaches that consider the individual’s unique circumstances, lived experiences and cultural contexts. Promote respectful dialogue grounded in cultural safety and trauma-informed care, recognizing that hesitancy may stem from multiple factors.

Factors influencing vaccine hesitancy: 
  • Limited understanding of vaccines/limited information available in their language of choice.  
  • Conflicting/misleading information. 
  • Information overload/burnout. 
  • Limited access to vaccination services (or needing to go to multiple locations for different vaccines). 
  • Financial barriers (e.g., ability to take time off, cost of travel). 
  • Mistrust in institutions or industry motives.  
  • Concerns about side effects, pain or anxiety. 
  • Misconception of vaccine effectiveness. 
  • Sociocultural or religious beliefs.

Improving access for underserved populations 

Culturally competent and safe care is essential to improving vaccination uptake and addressing inequities in the health system.52,53 

Supportive strategies51,53

Design supportive health care environments to create positive vaccination experiences, such as building trusted relationships, co-administration of vaccines to reduce travel time and costs, and embedding culturally safe practices. 

Build information environments with tailored communication and outreach (community-informed and culturally relevant) that fill in information gaps and counter misinformation. 

Indigenous considerations54

While overall vaccine confidence among First Nations, Inuit and Métis populations is high, coverage across regions remains uneven. These differences are shaped by systemic, social and intrapersonal factors that can act as barriers or facilitators to vaccine uptake. 

Barriers and facilitators

Barriers:

  • Mistrust in healthcare institutions
  • Patronizing or stigmatizing vaccine campaigns
  • Limited access to booking technologies
  • Language barriers
  • Travel challenges
  • Ineffective communication

Facilitators:

  • Clear, respectful communication about vaccine safety and importance
  • Prioritization of Indigenous populations in rollout
  • Consistency in vaccine brands for multi-dose series
  • Holistic supports (e.g., co-administering vaccines to reduce travel)

 

Barriers:

  • Circulation of misinformation within communities 
  • Anti-immunization attitudes within communities  

Facilitators:

  • Positive, trusting interactions with healthcare providers 
  • Supportive community environments 

 

Barriers:

  • Misconceptions about vaccines 
  • Previous negative health experiences 
  • Perception that alternatives (e.g., homeopathic medicine, vitamin D, natural immunity) are just as effective 
  • Preference for Traditional medicine over Western medicine 

Facilitators:

  • Altruism (desire to protect others) 
  • Trust in providers and health systems 
  • Strong personal perception of risk
