A health utility value of 1.00 indicates perfect health while a score of 0.00 indicates death. Negative values account for the fact that some health states are identified by the general public as being worse than death. To calculate a health utility score, health states for each response are converted using a look-up table and mathematical formula.
Body roundness index (BRI) is a calculated geometric index used to quantify an aspect of a person's individual body shape. Based on the principle of body eccentricity, it provides a rapid visual and anthropometric tool for health evaluation. [1] Introduced in 2013, the BRI calculation can be used to estimate total and visceral body fat.
The index was developed by Mary Charlson and colleagues in 1987, but the methodology has been adapted several times since then based on the findings of additional studies. [5] Many variations of the Charlson comorbidity index have been presented, including the Charlson/Deyo, Charlson/Romano, Charlson/Manitoba, and Charlson/D'Hoores comorbidity ...
A numerical value can be attached to each EQ-5D health state to reflect how good or bad a health state is according to the preferences of the general population of a country/region. Health state values can also be referred to as EQ-5D 'index values' or 'index scores'. The collection of index values for all possible EQ-5D states is called a ...
The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 is a measure of health status and an abbreviated variant of it, the SF-6D, is commonly used in health economics as a variable in the quality-adjusted life year calculation to determine the cost-effectiveness of a health treatment.
A Body Shape Index (ABSI) [1] or simply body shape index (BSI) is a metric for assessing the health implications of a given human body height, mass and waist circumference (WC). The inclusion of WC is believed to make the BSI a better indicator of risk of mortality from excess weight than the standard body mass index .
The Well-Being Index is an online self-assessment tool invented by researchers at Mayo Clinic that measures mental distress and well-being in seven-nine items. [1] [2] The Well-Being Index is an anonymous tool that allows participants to reassess on a monthly basis, track their well-being scores over time, compare their results to peers' and national averages, and access customized resources ...
Frailty Index (FI) = (number of health deficits present) ÷ (number of health deficits measured) For example, a person with 20 of 40 deficits collected has an FI score of 20/40 = 0.5; whilst for someone with 10 deficits, the FI score is 10/40 = 0.25. The FI takes advantage of the high redundancy in the human organism.
