A Survey for Charting Intake, Output, and Body Weight in the Electronic Medical Record

The accuracy of documentation of body weight and fluid balance in hospitalized patients is frequently questioned.

We conducted a survey to understand provider perceptions of the accuracy of intake, output, and weight charting in the electronic medical record. We sent a six-item questionnaire to nurses and physicians who provide inpatient service in a community-based teaching hospital of the Northeastern United States. We compared the response difference between nurses and physicians by Fisher exact test.

One hundred eight nurses and 39 physicians participated in the survey. Both nurses and physicians responded that the accuracy of documentation is crucial. However, only 25.7% of participating physicians and 38.3% of participating nurses considered that documentation in the electronic medical record is reliable. Both physicians and nurses assumed that the nurses are too busy to collect and document the data, and the variability of non-patient weight and variations in body weight measurement under different conditions account for inaccuracies in the documented body weight.

Assessing the accuracy of documenting intake, output, and body weight in the electronic medical record is warranted. Providers believe that educating patients about fluid balance and volume assessment help to improve the accuracy in charting intake, output, and body weight in the electronic medical record.
