Background
The NACA score is a widely used descriptive tool for assessing the severity of injuries and diseases in preclinical emergency medicine. However, due to its high degree of subjectivity, single use of the NACA score does not seem to be suitable for scientific questions, quality assurance in rescue services, or for the final retrospective assessment of the indication. For the Munich NACA (M-NACA) score, first described in 2005, data fields from the minimum emergency dataset were used to objectify the NACA score. The selection and value ranges of the data fields as well as the calculation scheme of the M‑NACA score were based on the minimum emergency dataset in the MIND2 version. In order to use the score for the minimum emergency dataset in the current MIND3.1 version, the calculation scheme was modified and adapted to the much larger content.
Procedure
All data fields of the MIND3.1 dataset suitable for estimating the preclinical emergency situation were transferred to the calculation scheme of the M‑NACA score. The aim was to include all available information about the situation at the location of the emergency in the NACA investigation in order to increase precision and validity.
Conclusion
By transferring the M‑NACA score to the minimum emergency data set MIND3.1 and the integration of additional data fields, the calculation scheme of the Munich NACA score could be developed further and made usable for current documentation by rescue services. For the calculation, 30 data fields from the MIND3.1 dataset are used. The calculation is based on a 260-criteria table, which are to be checked in the order of their consecutive numbering.
