Modified Nu-DESC — Modified Nursing Delirium Screening Scale

What this tool is and how to interpret its evidence

Modified Nu-DESC is a study-specific version of the five-domain Nursing Delirium Screening Scale. It retains the parent observational structure but makes the disorientation rating more explicit by incorporating two standard time-and-place orientation checks. The intended users were emergency nurses screening medical patients aged 70 years or older during routine work. The article describes a brief approach, but does not provide a stable completion-time estimate in its abstract; services should obtain the source before specifying workflow or scoring.

Brich and colleagues prospectively enrolled 315 consecutive older emergency patients and compared nurses' German Nu-DESC ratings with an independent criterion diagnosis. The unmodified scale had sensitivity of 66.0% and specificity of 91.0%. In an exploratory analysis of the same cohort, the operationalised disorientation approach increased sensitivity to 77.8% while specificity fell to 84.6%. That trade-off may be useful, but it is a same-sample modification rather than independent validation of a finished new tool.

The page should present Modified Nu-DESC as a version within the Nu-DESC family and exclude it from the independent-family count. It may explain the five-domain structure, routine nurse setting and broad nature of the modification without reproducing the full scale. The exact classification rule belongs in the publication. Until another cohort prospectively tests the modified procedure, its performance should be labelled derivation-only and should not be attributed to standard Nu-DESC.
