00:00
All right. Let’s talk about hazard reduction
because this is something people can forgot about.
00:04
First of all, spirometry is absolutely
indicated for the diagnosis of asthma.
00:10
Even five-year-olds should be able to try it.
00:14
And that's important because it cinches
the fact that there's some kind of reversibility
in terms of their FEV1
with the use of a short-acting beta agonist.
00:25
So, overall, the treatment goals for asthma: reduce
impairment associated with the illness
and reduce the number of exacerbations.
00:33
And that means finding triggers and allergens.
00:35
So, this might be pets.
00:37
It might be certain pollens
or other plant products
at certain times of the year,
but avoiding those triggers is key.
00:48
And if it's persistent asthma,
it's always worth considering allergy testing.
00:55
And the best approaches to
avoiding triggers are multifaceted.
00:59
So, that might mean a mask at certain times,
plus avoidance of the cat.
01:04
There's different ways.
01:06
So, usually, when it’s multipronged
as an effort to reduce triggers,
that’s going to be the most effective.
01:12
And simple things like wearing a mask or a scarf
can make a big difference in
exercise-induced bronchoconstriction.
01:18
I didn’t necessarily know this.
Maybe it’s because I’m from California.
01:20
We don't have that much cold weather,
but wearing a mask or a scarf can really help.
01:24
If a child, in particular,
has exercise-induced bronchoconstriction,
shouldn’t limit their play.
01:30
We don't want these kids sitting on
the sidelines, avoiding physical activity.
01:34
And, in fact, it may be a sign
when they have persistent
exercise-induced symptoms
that it's time to begin a controller medication.
01:42
Step up from just a beta agonist alone, short acting,
to using a corticosteroid to control their
symptoms a little better day to day.
01:51
Okay.
01:51
How do you use this inhaler?
Well, it’s an inhaler.
01:54
What’s that hard, right?
Well, this is a study of 73 children between 2 and 18 years
and they all had an asthma exacerbation.
02:01
They were tested on their use
of their metered-dose inhaler,
or MDI, only 45% can use it appropriately.
02:07
We provide spacers, like this
little girl here has a spacer.
02:10
That should allow for easier use of the MDI.
02:14
Unfortunately, this sample,
it didn't improve things at all.
02:17
44% still were misusing their MDI.
02:21
And they also noted that 17% of kids
who were told to be using their peak
flow meters were actually doing so.
02:27
These are kids with more moderate to severe asthma
and they weren’t following
through on the recommendations.
02:33
And that must get better with age, right?
You get older, you get wiser, you know
how to take care of yourself.
02:39
Well, this is 450 adults presenting
to the in emergency department.
02:42
So, similarly, patients who probably have less
control are coming to the emergency department.
02:47
Guess what their rate of improper
metered-dose inhaler use was?
45%.
02:52
So, nothing had improved between the time they were
kids with asthma to when they were adults with asthma.
02:58
They misused their MDIs at pretty much the same rate.
03:02
Why?
A lack of education, in the first place,
about how to use the inhaler appropriately
and not seeing somebody regularly and
follow-up to help reinforce those lessons.
03:12
And improper MDI use is a serious business.
03:16
It’s associated with a higher asthma symptom score
and it’s associated with more frequent
visits to the emergency department.
03:23
Therefore, bringing in the inhaler
and showing me as a physician
how they're using it is a critical
part of asthma management.
03:32
And I try to do that on
the majority of visits if I can.
