Accurate Weight Measurements - a MUST HAVE for LTC!

Accuracy of weight measurements is essential to the nutrition assessment of a resident in long-term care and sets the stage for nutrition intervention.  Weight measurement is used to calculate energy, protein and fluid needs; used as an indicator of nutritional and health status over time as changes in weight can often indicate other medical changes; and also used to dose certain types of medications.  Inaccurate weight measurements can result in an increased number of “unplanned” weight changes in the facility and affect the plan of care for the resident. 

Key points to consider in assuring weight accuracy:

• If possible, have the same staff member responsible for obtaining all weights.  This will assure consistency of procedure.
• Weigh residents at the same time of the day, in the same weight clothing each time they are weighed.
• Use type of scale appropriate for each individual resident’s weight, medical condition and ability to ambulate; balance scale to zero before weighing.
• Document type of scale used for measurement.
• If weighed in wheelchair, subtract weight of wheelchair from weight obtained.
• Be aware of casts, full catheter or colostomy bags, splints, prosthetics and other devices that can affect weight and document if these items are present.
• Compare weight to previous weight; if a large variance is noted (greater or equal to 5#) re-weigh the resident to verify the weight.
  * make sure to document as “re-weight”
• Calibrate scales at least once a month using manufacturer’s instructions for calibration to assure accuracy; if scale is electronic, batteries should be changed regularly.
