growthscreener's Introduction

growthscreener

The growthscreener package implements tools to evaluate child growth with respect to Dutch criteria for unusual growth. Application of these tools helps to identify children that meet criteria for criteria for referral from youth health care (JGZ) for follow-up with a general physician or paediatrician.

The current version implements Dutch guidelines for

height
weight
head circumference
language development

Installation

The following statements will install the growthscreener package

install.packages("remotes")
remotes::install_github("growthcharts/growthscreener")

Example

Find the advice for a very short girl:

library(growthscreener)
#> Loading required package: nlreferences

# a very short girl, 4 months old
msgcode <- calculate_advice_hgt(sex = "female", bw = 3250, ga = 40, dom = 0.367, y = 55)
msgcode
#> [1] 1045
cat(fold(msg(msgcode)))
#> Het advies volgens de JGZ-richtlijn lengtegroei is als volgt: Verwijzen naar
#> huisarts/kinderarts, omdat de lengte SDS < -3 is en het geboortegewicht >= 2500
#> gram is.

The height SDS at the age of about 4 months is equal to -3.255, which is the reason for referral.

Background

growthscreener's Issues

Make language development screening available to JAMES

growthscreener 1.20.0.9000 extends the list_screeners() function to include 4000-codes for language development. Making the screener available to JAMES still requires a few steps:

Extend bdsreader::read_bds() to save Van Wiechen items 41-46 by default to JAMES internal format. There is already a switch append_ddi, but that should be refined to filter only items 41-46;
Create growthscreener::calculate_advice_lgd() that implements the functionality of calculate_advice_devlang(), but using the default gsed 9-position naming schema and the long format used in the xyz component created by read_bds(). Perhaps calculate_advice_lgd() could wrap calculate_advice_devlang();
Test that calculate_advice_lgd() and calculate_advice_devlang() do the same from different argument specifications;
Extend argument yname in growthscreener::screen_curves_tgt() to include the lgd (language development) code;
Extend growthscreener::screen_curves_tgt() with a call to calculate_advice_lgd();
Add test for growthscreener::screen_curves_tgt();
Update NEWS and version in JAMES.
