In this tutorial, you will learn about Patient Anthropometric Data

View the tutorial video.

Anthropometric data, such as the patient’s weight, length, and head circumference, can be recorded in the Anthropometric Data Window. The following calculated values also appear in this window:
•    Weight change from birth (%)
•    Average daily weight change from birth to current day (g)
•    Change in weight from yesterday if weight was entered for both days for this patient (g and g/kg)
•    Average weekly growth in length from birth to current day (cm)
•    Average weekly growth in head circumference from birth to current day (cm)
•    Surface area (sq m).

Weekly averages for length and head circumference can be calculated only if data have been entered for 2 days that are at least 4 days apart.

 
 
Caution Make sure everyone who uses NEONOVA and its printouts knows the definitions of these weights and that Analysis Weight, when it differs from Actual Weight, is used properly.


Actual Weight
Previously identified in earlier versions of NEONOVA as Weight, this field is now labeled Actual Weight to distinguish it from Analysis Weight. This field is intended to contain the current measured weight of the infant.

Analysis Weight
You can use a weight other than Actual Weight for nutrient intake calculation purposes. In certain cases, it may be local practice to perform some calculations based on a specific weight, such as birth weight, even if it is not the infant’s current weight.
Analysis Weight defaults to Actual Weight, the weight entered in the Day Add Window or subsequently modified in the Anthropometric Data Window. If you do not wish to use a different Analysis Weight for a patient, do not change the default value and the Analysis and Actual Weights will be the same. To change the Analysis Weight, simply enter the desired value into the Analysis Weight field in the Anthropometric Data Window.

See Annex 3, “Calculations,” for detailed information about how these values are derived.

 


Hint Analysis Weight is a weight such as birth weight or estimated “dry” weight that is used instead of Actual Weight for calculation purposes. For example, before birth weight is regained after early postnatal weight loss, some Neonatal Intensive Care Units prefer to estimate nutrient requirements or express nutrient intakes relative to birth weight rather than Actual Weight. Actual Weight is the patient’s measured body weight on the date identified. Analysis Weight and Actual Weight may be identical or different. In the Anthropometric Data Window, Analysis Weight defaults to Actual Weight, but it can be changed there if desired. Remember, nutrient intake calculations, expressed per kg of body weight, are based on the Actual Weight unless you are asked a selection.

Data variable selection
 

 
The batch edit icon    brings up a window with all pre-defined variables.
 

You may only provide data to these four variables.  All other variables appearing subsequently are calculated based on these entries or from values from previous action day.

At creation, by default, Analysis Weight and Actual Weight inherit from the Action day weight provided at day edition.
 

Also, any changes made to the action day weight, will update anthropometric analysis and actual weight.


 
The import icon   brings up a window with anthropometric variable values entered from Action date.

 


NOTES:    Action patient weight vs actual weight vs analysis weight

The Action day weight is mandatory when creating a new daily statistic for a patient.

Also, any changes made to the action day weight will update anthropometric analysis and actual weight when inside the edit anthropometric data window.

Actual weight should be the preferred weight used to reflect the real weight evolution.

Analysis weight is a test variable that should be used when evaluating scenarios.


Warning You must enter data patient weight.  Because most nutrient information is expressed by NEONOVA on a per-kg basis, you will have limited benefit from the results if you enter non relevant information. You are strongly encouraged to enter an accurate and current weight value for the patient each day that data are entered.
 
Importing Anthropometric values from another date

The import icon   brings up a window with Anthropometric data entered from Action date. 

By selecting a specific range, these values will be copied to the current action date.  If the selection contains Anthropometric data already entered in the current action date, the imported values will overwrite any current existing values.


Changing birth date information

If you change the birth date, the age is recalculated within the Action day. To see the results, you will need to apply a refresh grid.
 

Similarly, to have all anthropometric data being recalculated for a patient, access the first Patient Action day record entry and from the Anthropometric window, use the batch entry icon and accept values with the ok button.  All ratios and values will be recalculated for that patient.
