    Additional information

    The Devine formula1 is not referenced to a particular data set.

    Instead, the Devine formula was based on the empiric estimates of Devines' mentor, Dr. Margaret McCarron. Future validation studies were performed by peers (Robinson et al, 1983; Miller et al, 1983), who argued that equations for ideal body weight would have to be derived from actual data and not empiric estimates if they were to be applied in future pharmacokinetic studies. The equations derived by both Robinson and Miller were strikingly similar to those proposed by Devine (Pai & Paloucek, 2000).

    Result interpretation

    Multiple ideal body weight formulas have been developed to assist physicians with dosing weight-based medications. Please confirm with your local pharmacy whether ideal or actual body weight should be used for medication dosing. 

    Definition of ideal body weight:
    The term ideal body weight (IBW) was coined based on historical data of weights for adult men and women that compared the relative mortality of persons of different height–weight combinations (Knapp, 1983).

    Model performance:
    Pai & Paloucek (2000) reported that alternative IBW equations by Miller et al (1983) and Robinson et al (1983) both resulted in similar results when compared with the Devine formula (Devine, 1974). Therefore, any one of these equations may be used to estimate IBW.
