play00:19

hand side you can see the function menu

play00:21

within Atlas and we'll click on data

play00:22

sources when we click on data sources

play00:25

you first are able to select any of

play00:28

these sources of data that have been

play00:30

configured within Atlas and then you can

play00:32

select your report of interest here

play00:35

we're selecting drug exposure once you

play00:38

select the drug exposure report you will

play00:41

see a tree map visualization which shows

play00:43

you all of the concepts within the drug

play00:45

exposure table the size of the box

play00:49

represents the prevalence of that

play00:51

concept and the color of the box

play00:52

represents the number of Records per

play00:54

person that concept represents if we

play00:57

hover over any particular box we can see

play01:00

additional information here for example

play01:03

I have hovered over lisinopril

play01:05

10 milligram oral tablet it has a

play01:08

prevalence of 2.5 6 percent meaning 2.2

play01:11

million patients in this data set have

play01:13

lisinopril 10 mg oral tablet in the drug

play01:16

exposure data domain and for those

play01:19

people on average they have 8.8 records

play01:23

of lisinopril 10 mg or old tablet if I

play01:26

click on any of these boxes we will

play01:29

identify a drill-down report which will

play01:33

provide additional information to

play01:35

characterize this particular concept

play01:37

within the data source now that I've

play01:40

clicked on lisinopril 10 mg oral tab we

play01:43

can see the drill down report provided

play01:45

below the first graph displays the

play01:48

concept prevalence of this concept on

play01:51

the x-axis we see time in in years so in

play01:56

this particular data source going from

play01:58

2002 to 2007 teen we have a trellis

play02:01

representing age deciles going from 0 to

play02:04

9 to 90 to 99 and on the x-axis we have

play02:08

concept prevalence per thousand persons

play02:10

within each graph you see two lines here

play02:13

representing stratification by gender

play02:16

the line in blue represents males in the

play02:18

line in pink represents females so this

play02:22

graph can show us for example that

play02:24

amongst patients who are having exposure

play02:27

to less interval 10 mg oral tablet it

play02:29

appears that the use of this drug has

play02:31

increased over time we see that it is

play02:34

used more in an older population than a

play02:36

younger population and is used more in

play02:38

men than women if I scroll down further

play02:42

we have a plot that shows the concept

play02:44

prevalence by month here the x-axis

play02:46

represents calendar month the y-axis

play02:49

represents per thousand persons if I

play02:52

hover over any particular month I can

play02:54

identify information such as here June

play02:58

2012 the prevalence was 8 per thousand

play03:02

persons this allows you to assess the

play03:05

stability of the concept over time the

play03:11

next plot shows us the provenance of the

play03:13

data represented by the type concept ID

play03:15

here we can see in the donut plot the

play03:18

proportion of records that have come

play03:19

from different sources here this record

play03:22

for this source 94 93.6%

play03:26

of the records come from a prescription

play03:28

dispensed in a pharmacy while the

play03:30

additional 6.4% seemed to be

play03:32

prescriptions dispensed through

play03:33

mail-order the graph to the right here

play03:37

represents the age at first occurrence

play03:40

here we see this is stratified by gender

play03:43

and for each of the genders we have a

play03:46

box plot the box plot then allows us to

play03:49

know a patient's age at the first

play03:52

occurrence of the lisinopril 10 mg oral

play03:54

tab so here we can see amongst women the

play03:57

median age was 60 at the time of first

play04:00

exposure finally there is a plot of

play04:03

frequency distribution showing you the

play04:05

cumulative distribution of the number of

play04:07

Records for this particular concept

play04:09

amongst the patients who were exposed so

play04:12

here we can see that everybody has at

play04:14

least one record but we can see that

play04:16

many individuals have 2 3 4 all the way

play04:20

out to 13 are records of lisinopril

play04:24

within their medic

play04:25

record the drug exposure report allows

play04:28

us to explore any particular concept in

play04:30

the drug exposure table both by

play04:32

selecting any concept in this tree map

play04:35

view but also by being able to explore

play04:38

the information in this tabular view so

play04:41

if we were interested in a particular

play04:43

job like hydrochlorothiazide we could

play04:48

search for that drug name and we would

play04:51

see all associated records and simply

play04:53

selecting a record from the table would

play04:56

allow you to determine the and explore

play04:59

the concepts existence in this

play05:02

particular data source so for example

play05:05

here by selecting on hydrochlorothiazide

play05:07

50mg or all tab we can see the use of

play05:10

hydrochlorothiazide in the databases

play05:13

buying those same graphs

play05:17

um now going to select a different

play05:21

report the drug error report the drug

play05:24

error report provides information about

play05:27

the ingredients used in continuous

play05:30

persistence exposure here we are rep the

play05:36

same representation with a treemap

play05:38

visualization in a tabular display what

play05:41

is different with the drug error report

play05:43

however is that drugs have been

play05:45

aggregated to the ingredient level and

play05:48

rather than representing the number of

play05:50

records we can now represent the span of

play05:53

time that a person is exposed to a

play05:55

particular drug so if I search for

play05:57

lisinopril we can now see that there is

play06:00

one record for the active ingredient

play06:02

lisinopril we can see that there are six

play06:05

million patients in this particular data

play06:06

source represented a prevalence of 7%

play06:08

and that on average patients on

play06:10

lisinopril were exposed for about 300

play06:13

days I can click on any record in this

play06:18

table to be able to get to a drill down

play06:20

reporting which will provide us

play06:22

additional information so here I can see

play06:25

the same plot of concept prevalence by

play06:28

age gender and year to see the pattern

play06:31

of lisinopril use I can see a pattern of

play06:34

the prevalence by month

play06:36

here we see

play06:38

Spike's in the data at January

play06:41

indicating that that's a moment in time

play06:42

when we see continuous use and we

play06:45

further see a graph broken down by age

play06:47

at first exposure between the drug

play06:51

exposure report in the drug error report

play06:53

it provides you a summary of information

play06:57

that allows you to understand both which

play07:00

concepts are occurring how those

play07:02

concepts roll up to an ingredient and

play07:05

how long patients are exposed for

play07:07

periods of time that's all for our drug

play07:11

reporting in the data sources if you

play07:13

have additional interest in other

play07:15

reports and data sources or other
