hierarchy: Applies the comorbidity hierarchy to the comorbidity groups

In gforge/comorbidities.icd10: Calculates Comorbidity Indices Based on ICD-9/10

Description

The hierarchy functions generally remove less complicated diseases when more complicated diseases are present. For instance if a metastasis code is present then the solid tumor code is obsolete.

Usage

hierarchy.ahrq(out)

hierarchy.elixhauser_Elixhauser1998(out)

hierarchy.elixhauser_Quan2005(out)

hierarchy.charlson_Deyo1992(out)

hierarchy.charlson_Quan2005(out)

hierarchy.charlson_Sundarajan2004(out)

hierarchy.charlson_Armitage2010(out)

Arguments

out	A matrix/data.frame/vector with the comorbidity groups outputted from the cmrbdt.finder.*() functions

Value

out Returns the same as the input but with the hierarchy applied
