Description

These functions obtain index values for the EQ-5D descriptive system using the algorithm developed by Cleemput (2010).

Usage

1
2
index3L(MO, SC, UA, PD, AD)
index5L(MO, SC, UA, PD, AD)

Arguments

MO

score for mobility; numeric or character vector.

SC

score for self-care; numeric or character vector.

UA

score for usual activities; numeric or character vector.

PD

score for pain/discomfort; numeric or character vector.

AD

score for anxiety/depression; numeric or character vector.

Details

The scores can take values 1, 2, 3 for function index3L, and values 1, 2, 3, 4, 5 for function index5L.

The index values are calculated using the algorithm developed by Cleemput (2010):

1-X = 0.152*INT + 0.074*MO + 0.083*SC + 0.031*UA + 0.084*PD + 0.103*AD + 0.256*N3

where INT is a dummy indicating less than perfect health, and N3 is a dummy indicating any dimension at level 3

The index values for the EQ-5D-5L are obtained by mapping the the EQ-5D-5L health states to EQ-5D-3L health states, following van Hout et al. (2012).

Value

A data.frame containing the scores and index values.
