Guidance on citations and reference

Publications shall reference the software as The Johns Hopkins ACG® System and include the software version number used for the research. First occurrences of terms shall be preceded by ACG® System. Example: ACG® System Rx-Defined Morbidity Groups (Rx-MGs) may be shortened to Rx-MGs on subsequent occurrences. Redundant use of ACG® System may be omitted where meaning is clear: Example: ACG® System Rx-Defined Morbidity Groups (Rx-MGs) and Coordination metrics were used for identifying high risk individuals. In the interest of replicability, we encourage academicians to incorporate as much detail as possible about which models and/or data processing options were applied in their research. Example: Summary Statistics tab indicates the ACG Predicted total cost model DxRx-PM-total cost-lenient dx-> total cost could be described as “Predicted total costs scores from the ACG System were based on both diagnoses (any occurrence) and pharmacy information.”
