You think you know asthma?

A 25 y/o smoker presents to the ED with SOB and tells you her asthma is acting up. You think to yourself, “I love the crashing asthma patient!” Within 5 minutes bipap is bedside, solumedrol is given and somehow she’s already on her 3rd round of combinebs. “Nailed it!”

She’s feeling pretty good now and breathing better. The room’s starting to get chaotic, but you’re a good doctor so you make sure to write her scripts for a course of oral corticosteroids and you even remember to say, “see your doctor in the next week” as she signs the discharge papers. Job well done!… right?

There are soooooooo many things missing here it hurts. Sure the course of steroids will cool everything off for a few more days, but what about a week from now when she’s back chain-smoking with her buds? Does she have albuterol at home? Is she going to see her PMD? Does she have a PMD??? Well you can ask her in 2 weeks when she comes back. (Catch my point?)

Controller versus Rescue medications

We know that asthma is a chronic inflammatory disease of the lungs. People with mild and occasional flares just use their albuterol and call it a day. However, for anyone using their albuterol more than 3 times/week. Their asthma is poorly controlled. It is time to start a controller medication to attack that ongoing inflammation. The first line and most effective controller medications are inhaled corticosteroids (1).

Yes! We can prescribe them and there is evidence that we should start prescribing these meds from the ED.

Rowe et al. published a placebo-controlled, double blind, RCT of 1,006 adult asthmatics being discharged from an ED in Canada and found that compared to placebo, patients who were started on an inhaled corticosteroid (Budenoside 400μg BID) had a 48% decrease in repeat hospital visits at 21 days, had better quality of life scores, had significantly less symptoms and used their albuterol inhalers almost 50% less than those in the placebo group. The placebo group had more adverse events (sorethroat and hoarsness) and an equal number of outcomes thought to be common with inhaled steroids (acne, fluid retention and insomnia).

NNT to prevent relapse was 9! (3)

Others who support starting inhaled steroids in the ED are:

  • NIH/NAEPP Expert Panel Report 3 (4)
  • The Global Initiative for Asthma (GINA) 2008 guidelines
  • Tintinalli’s Emergency Medicine: A Comprehensive Study Guide, 7e (5)

Moral of the story, you may have halted an exacerbation, but be a doctor and treat the underlying disease! And as a bonus, you will have one less patient crowding the asthma room next week.

*Extra Controller Medication Tips: If your patient is already on an inhaled corticosteroid, add a long-acting beta agonist (like formoterol or salmeterol) or get fancy and start them on a combined ICS-LABA inhaler twice daily (1).

 

Other important check points before you send that person home:

Check Compliance and Inhaler Technique.

Poor technique is associated with poor disease control, poor adherence if therapeutic benefit not experienced, more hospital visits and increased resource utilization (7).

Avoid Triggers and Quit Smoking!!

Tell them to avoid their triggers:

  • Seasonal allergies? Second generation anti-histamines like Claritin and Zyrtec have been shown to reduce ED visits for asthma (3).
  • Exercise-induced? Tell them to pre-treat with albuterol before they run.
  • For the love of all the things, encourage them to quit smoking:
    • 20% of asthmatics smoke. Smoking asthmatics have more severe disease, more hospital admissions, faster decline in lung function and a higher risk of death compared to non-smokers (1). Smoking also disrupts anti-inflammatory effects of asthma medications making them less effective. Cessation has been shown to improve lung function and steroid resistance (1).

*Note that they may have a temporary worsening of asthma immediately following smoking cessation.

 

But how can we get them to quit?!

Kanis et al. found that parents who perceived smoking as a risk to their child’s health were more likely to have a high motivation to quit smoking (8).

A recent systematic review of various smoking cessation interventions in the ED revealed only 2 studies had significant results; both used motivational interviewing and follow-up phone calls (9). Motivational interviewing is fascinating and a VERY effective communication skill that we should all learn to help patients see the error in their way, or as this video calls it, it’s a Jedi Mind Trick.

Check out this sample cartoon on smoking cessation using the 5 R’s of quitting (Relevance, Risk, Rewards, Roadblocks, Repetition):

 

 

Or if you prefer reading, this website lays out a brief intervention that you can add to your practice:

Bottome line: Smoking is bad for asthma, but the best way for us ED docs to intervene is still unknown, but motivational interviewing (MI) may be effective.

 

Follow Up

Ok you’re right a lot of this is pretty IM-ish. Therefore, send them for follow-up with either an asthma specialist or a PMD. Sin et al. found that follow-up within 30 days of an asthma related ED visit was associated with a reduced 90-day re-admission rate (3).

 

In Conclusion (after your patient is back to breathing and talking):

Step 1. Ask about triggers – recommend avoidance and briefly talk about their motivation to quit smoking.

Step 2. Technique – Make sure they’re using their inhaler correctly.

Step 3. Educate them on controller and rescue medications

*Make sure they know:

– to keep the rescue medication with them at all times.

– use the controller medication everyday regardless of symptoms.

– re-iterate that the controller medication will not help them in acute exacerbation.

– don’t be afraid to start that inhaled corticosteroid!

Step 4. Set them up with follow up.

*Many of these young asthmatics do not have PMDs.

… Someone’s gotta prescribe that awesome controller med you started.

Step 5. Prescribe refills – for albuterol and their other controller meds.

*The controllers are necessary to prevent relapse after the oral steroids are completed.

Step 6. Enjoy a quieter asthma room next week and feel good, you saved another one!

    Excellent post! All good points but I think the inhaler technique is particularly important and often the cause of patient’s poor symptom control and it’s so easy to correct if you take the time.

    Consider allergic rhinitis as a cause of an asthma exacerbation and consider treating with nasal steroids (may be more effective than antihistamines). This is a fairly benign medication that may get to the root of the problem in some cases.

    From a recent NEJM review:

    “Most people with asthma have rhinitis. The presence of allergic rhinitis (seasonal or perennial) significantly increases the probability of asthma: up to 40% of people with allergic rhinitis have or will have asthma.”

    risk factor for adult-onset asthma. J Allergy Clin Immunol 2002;109:419-25
