Now lets add some more clinical data to fifthTest.xml and save it as SeventhTuteTest.xml.First we add a HBA1c result

Add it between </vitals> and </singlePatient> at the end:

    <observations>
<observationCode code="43396009"
codeSystem="2.16.840.1.113883.6.96"
codeSystemName="SNOMED-CT">
<displayName value = "Hemoglobin A1c measurement " />
<translation code="4548-4"
codeSystem="2.16.840.1.113883.6.1"
codeSystemName="LN">
<displayName value = "Hemoglobin A1c/Hemoglobin.Total In Blood" />
</translation>
</observationCode>
<dateTime value = "20160616" />
<value xsi:type = "PQ" value = "9.0" unit = "%"/>
</observations>
<diabeticFootObservations>
<diabeticFootExamDate value = "20160616" />
<leftDorsalisPedisPulseFull value = "false" />
<rightDorsalisPedisPulseFull value = "true" />
<leftPosteriorTibialPulseFull value = "true" />
<rightPosteriorTibialPulseFull value = "true" />
<leftAnkleBrachialIndex value = "0.7" />
<rightAnkleBrachialIndex value = "0.9" />
<anyFootDeformity value = "false" />
<anyNeurologicalChanges value = "false" />
<anyUlcerPresent value = "false" />
</diabeticFootObservations>

Cut and paste the following GELLO into a new workspace:

    Imports ExtendedDiabeticFoot
Context ExtendedDiabeticFootExample_SinglePatient
    Let lastFootExam: DiabeticFootObservations = diabeticFootObservations->
sortedBy(diabeticFootExamDate)->last()
    Let lastHBA1c: PQ = observations->
select(o|o.observationCode.code='43396009')
->sortedBy(dateTime)->last().value.oclAsType(PQ)
    --flag a high risk situation
    Let highRiskDiabeticFoot: Boolean =
(lastFootExam.leftAnkleBrachialIndex < 0.9 or
lastFootExam.rightAnkleBrachialIndex < 0.9) or
(lastFootExam.leftDorsalisPedisPulseFull = false or
lastFootExam.rightDorsalisPedisPulseFull = false) or
lastFootExam.anyFootDeformity = true or
lastFootExam.anyNeurologicalChanges = true or
lastFootExam.anyUlcerPresent= true
and
lastHBA1c > factory.PQ(7.5, '%')
    If highRiskDiabeticFoot then 'High Risk DiabeticFoot - consider referral'
else
''

 

endif

 

 

And after compiling and saving it say as tuteSeven.gello , run:
