The BMI is a weight-to-height ratio, calculated by dividing a person’s weight by the square of the person’s height and multiplying the results by a value that changes based on the unit of measure used to enter the height and weight. It indicates whether the person is underweight, normal weight, overweight, obese or morbidly obese.
Hospice clinicians regularly use the BMI to determine how well a patient is thriving. A reduction in BMI can be an indicator of impending death. Home care clinicians are now being encouraged to assess the BMI as a risk for potential skin breakdown and pressure ulcer development. With the release of OASIS-C2, a new data element has been added to capture the patient’s height and weight on the assessment. Although the BMI is not entered on the assessment, clinicians are encouraged to obtain the results for use in care planning.
How is it Used?
Calculating the BMI can be done using static tables or online BMI calculators. Using the following interactive calculator clinicians enter the height and weight and the system displays the results. A dial depicts the results of the BMI using a scale from underweight to morbidly obese.
