traumar: Calculate Metrics for Trauma System Performance
Hospitals, hospital systems, and even trauma systems that
provide care to injured patients may not be aware of robust metrics
that can help gauge the efficacy of their programs in saving the lives
of injured patients. 'traumar' provides robust functions driven by
the academic literature to automate the calculation of relevant
metrics to individuals desiring to measure the performance of their
trauma center or even a trauma system. 'traumar' also provides some
helper functions for the data analysis journey. Users can refer to the
following publications for descriptions of the methods used in
'traumar'. TRISS methodology, including probability of survival, and
the W, M, and Z Scores - Flora (1978)
