popnorm: Belgian population norms for the EQ-5D-5L and EQ-5D VAS...

In brechtdv/EQ5D.be: EQ-5D Index Values and Population Norms for Belgium

Description

These functions provide Belgian population norms for the EQ-5D-5L and EQ-5D VAS instruments.

Usage

# wrapper function
popnorm(age, sex, region, year, parameter = "INDEX")

# specific functions
popnormINDEX(age = NA, sex = "B", region = "BE", year = 2018)
popnormVAS(age = NA, sex = "B", region = "BE", year = 2018)
popnormMO(age = NA, sex = "B", region = "BE", year = 2018)
popnormSC(age = NA, sex = "B", region = "BE", year = 2018)
popnormUA(age = NA, sex = "B", region = "BE", year = 2018)
popnormPD(age = NA, sex = "B", region = "BE", year = 2018)
popnormAD(age = NA, sex = "B", region = "BE", year = 2018)
popnormANY(age = NA, sex = "B", region = "BE", year = 2018)

Arguments

age	age of the individuals; should be NA (all age) or integer value between 15 and 100.
sex	sex of the individuals; should be "M" (male), "F" (female), or "B" (both).
region	region of the individuals; should be "BE" (Belgium), "BR" (Brussels), "FL" (Flanders), or "WA" (Wallonia).
year	year of the survey; should be 2013 or 2018.
parameter	which population norms to obtain; see 'Details'.

Details

There are 8 parameters for which population norms are available:

INDEX	EQ-5D-5L index score.
VAS	EQ-5D-5L visual analogue scale.
MO	Any problems of mobility.
SC	Any problems of self-care.
UA	Any problems with performing usual activities.
PD	Any problems of pain/discomfort.
AD	Any problems of anxiety/depression.
ANY	Any problem in the EQ-5D-5L descriptive system.

All population norm estimates are derived from the Belgian Health Interview Surveys 2013 and 2018. The Visual Analogue Scale was only included in the BHIS 2013.

Value

A data.frame containing the population characteristics and population norms (mean, lower confidence level, upper confidence level, and standard error).

Examples

## Overall population norms for EQ-5D-5L index and VAS
popnormINDEX()
popnormVAS(year = 2013)

## EQ-5D-5L index population norm for specific individuals
ind <-
  data.frame(age = c(30, 50, 90),
             sex = c("F", "F", "M"),
             region = c("FL", "WA", "BR"))
with(ind, popnormINDEX(age, sex, region))

## Plot age trend in problems on all 5 EQ-5D-5L dimensions
par(mfrow = c(1, 5))
plot(15:100, popnormMO(15:100)$mean,
     type = "l", ylim = c(0, 1), main = "MO")
plot(15:100, popnormSC(15:100)$mean,
     type = "l", ylim = c(0, 1), main = "SC")
plot(15:100, popnormUA(15:100)$mean,
     type = "l", ylim = c(0, 1), main = "UA")
plot(15:100, popnormPD(15:100)$mean,
     type = "l", ylim = c(0, 1), main = "PD")
plot(15:100, popnormAD(15:100)$mean,
     type = "l", ylim = c(0, 1), main = "AD")
