INTRODUCTION
Focus on nutritional risk
detection.
An alert software was used.
Malnutrition often goes
unnoticed.

MALNUTRITION PREVALENCE
Malnutrition is a serious concern.
The prevalence of malnutrition
problems is higher than believed.
It’s a serious underestimated problem.
The prevalence is 30%, out of which
70% goes undiagnosed..
www.hl7latam.org 5
MALNUTRITION FACTORS
Factors which have negative impact on nutrition:
Difficulties in monitoring weight.
Patients do not like hospital food.
They may lose appetite.
The disease itself consumes energy.
Doctors may neglect the nutritional aspect. They
focus mainly on the disease and studies, and not on
nutritional aspects.

History Project
Our aim to diminish the
malnourishment rate.
Nutritional aspects assessed by
doctors.
Multidisciplinary approach.
Creation of an automatic alarm.

CPOE
Positive effects
delay in order completion and processing
duplicate orders,
overdoses,
allergic reactions and drug interactions.
Negative effects
Alert fatigue

THE ALERT ENGINE
The alert engine in .NET and in C#.
We used different standards.
LOINC to laboratory data
ICD10 to medical record data.
HL7 2.4 to transfer data.

RESULTS
CONCLUSION
The nutritional risk alert we built was of
significant help.
Detection of malnutrition in patients
increased by 14%.
It is very important to use alerts.
Physicians using alerts could diagnose
more problems.

DISCUSION
It is important to avoid
overabundance of alerts.
Early detection of malnutrition
plays a fundamental role in
reducing morbidity in patients.
