Zusammenfassung
Anliegen Inwieweit lassen sich Überlebenszeiten bei Demenz aus dem Punktwert des Mini-Mental-Status-Tests berechnen? Methode Bei 145 Demenzpatienten wurde anhand von Cox-Regressionsanalysen das Sterberisiko für Demenzschweregrade und MMST-Einzelwerte berechnet. Ergebnisse Gemäß Cox-Regression erhöht sich das relative Sterberisiko pro Stufe im Demenzschweregrad (leicht / mittel / schwer) je um 36,2 % (p = 0,023), pro abnehmendem MMST-Punkt um 4,1 % (p = 0,005). Schlussfolgerung Der MMST-Punktwert kann als Prognosefaktor im Rahmen individueller Beratung und Planung sowie für gesundheits- und sozialpolitisches Management herangezogen werden.
Abstract
Objective Evaluation of the predictive power of the Mini-Mental State Examination (MMSE) for survival analyses of dementia patients. Methods In an 8-year follow-up study for 145 dementia outpatients the survival and relative death risks (hazard ratios) were calculated with Kaplan Meier and Cox-regression analyses. Results Following Cox-regression the relative death risk increases by 36.2 % per severity level of dementia (mild / moderate / severe), p = 0.023. Per single MMSE point lost, the relative death risk rises by 4.1 % (p = 0.005). Kaplan Meier analysis supports the result. Conclusions MMSE scores may in fact be used for dementia survival prognoses in counseling family and professional caregivers of dementia patients, but also for socioeconomic management of the increasing dementia burden for society.
