multimorbidity - Harmonizing Various Comorbidity, Multimorbidity, and Frailty
Measures
Identifying comorbidities, frailty, and multimorbidity in
claims and administrative data is often a duplicative process.
The functions contained in this package are meant to first
prepare the data to a format acceptable by all other packages,
then provide a uniform and simple approach to generate
comorbidity and multimorbidity metrics based on these claims
data. The package is ever evolving to include new metrics, and
is always looking for new measures to include. The citations
used in this package include the following publications: Anne
