Hi, my name is Adrian Horowitz and I'm going to be presenting on
- 00:06 - 00:09
the difference between relative risk and absolute risk.
- 00:10 - 00:13
So what do the numbers really mean?
- 00:15 - 00:16
Relative risk
- 00:16 - 00:21
is the percentage of the risk of one outcome occurring as opposed to another.
- 00:21 - 00:23
In midwifery practice.
- 00:23 - 00:25
This is usually in the context of providing
- 00:25 - 00:30
an intervention or treatment or not providing that intervention
- 00:30 - 00:31
for clients.
- 00:31 - 00:34
This comes up when deciding between different types of prenatal care they want
- 00:36 - 00:37
absolute risk.
- 00:37 - 00:40
Is the chance of an event occurring in general or
- 00:40 - 00:44
the probability of an outcome occurring within a certain population.
- 00:44 - 00:45
For midwives,
- 00:45 - 00:48
this is more individualized method of determining
- 00:48 - 00:51
the necessary care practices for each client
- 00:51 - 00:52
for clients,
- 00:52 - 00:54
this allows them to understand their
- 00:54 - 00:56
individual risks of experiencing certain outcomes
- 00:57 - 00:59
in the context of their own health parameters
- 01:01 - 01:02
absolute risk
- 01:03 - 01:07
is like your baseline risk for getting a disease regardless of intervention.
- 01:07 - 01:11
Whereas relative risk is your chance of getting the disease
- 01:11 - 01:14
with the use of intervention regardless of your baseline.
- 01:15 - 01:17
So in order to understand your true risk,
- 01:17 - 01:19
you have to compare both of these values.
- 01:20 - 01:22
A relative risk statement will sound something like
- 01:22 - 01:27
this intervention will reduce your chances of this outcome by x percentage.
- 01:27 - 01:30
Making it seem as though without that intervention
- 01:30 - 01:34
you are at a 100% chance of experiencing said outcome.
- 01:34 - 01:35
However,
- 01:36 - 01:36
in reality,
- 01:37 - 01:40
this relative value needs to be compared with the absolute value.
- 01:40 - 01:43
You might hear that a person's chance of experiencing
- 01:43 - 01:45
a heart attack is one out of 100,
- 01:45 - 01:47
which is an absolute statement.
- 01:48 - 01:52
Then you hear that a certain treatment reduces the chance of a heart attack by 30%.
- 01:53 - 01:54
This is a relative statement.
- 01:56 - 02:00
All this really means is that your actual risk of getting a heart attack
- 02:00 - 02:04
Becomes .7 out of 100 with that treatment,
- 02:05 - 02:08
that is what the treatment is really doing for you.
- 02:08 - 02:09
It's the true benefit.
- 02:10 - 02:12
So when you look at it this way it's easier
- 02:12 - 02:15
to weigh the risks and benefits of interventions and medications.
- 02:20 - 02:24
So why what is the pertinence for midwifery care?
- 02:24 - 02:25
Um
- 02:27 - 02:28
we can,
- 02:28 - 02:32
for midwives provide more accurate evidence when informing clients
- 02:33 - 02:37
for midwives. We can also provide individualized care decisions for clients.
- 02:38 - 02:42
For clients helps to understand their individual risk for certain outcomes.
- 02:43 - 02:47
And for everyone involved to have a clear understanding of
- 02:47 - 02:50
the true risks and benefits of an intervention or treatment.
- 02:51 - 02:54
The reason it matters for midwifery care is because when we
- 02:54 - 02:58
are engaging with shared decision making or informed decision making,
- 02:58 - 03:01
we want to be able to give our clients accurate research evidence
- 03:01 - 03:05
that informs them of their individual risk of experiencing certain outcomes.
- 03:06 - 03:09
This is a key element for him informed consent as well,
- 03:09 - 03:11
clients can have a clear picture,
- 03:14 - 03:15
excuse me,
- 03:15 - 03:17
clients can have a clear picture of their
- 03:17 - 03:19
risks and benefits when making consent decisions,
- 03:20 - 03:24
awareness of true risk leads to better health outcomes for clients as well.
- 03:24 - 03:28
When accurate information is utilized in care decisions,
- 03:28 - 03:31
the health outcomes of those decisions are improved.
- 03:34 - 03:37
So for example, in midwifery care,
- 03:38 - 03:41
When doing research, you might see a relative statement that says
- 03:41 - 03:47
magnesium supplementation reduces the risk of developing preeclampsia by 24%.
- 03:48 - 03:50
Or an absolute
- 03:50 - 03:51
statement
- 03:51 - 03:53
Is according to the CDC,
- 03:53 - 03:58
there's a one in 25 chance of developing preeclampsia in pregnancy.
- 03:59 - 04:03
You would want to use both of these values when making a care decision.
- 04:05 - 04:08
Another relative statement you might see is the use of Utero tonics in
- 04:08 - 04:12
the third stage of labor reduces the risk of hemorrhage by 73%.
- 04:13 - 04:17
An absolute statement would be according to the March of Dimes,
- 04:17 - 04:24
one in five out of 100 or 1-5% of birthing people experience postpartum hemorrhage.
- 04:24 - 04:29
Again, both of these values need to be considered when finding a client's true risk.
- 04:34 - 04:35
These are my references
- 04:38 - 04:39
and thank you so much.
