ObjectiveTo evaluate the diagnostic accuracy (DA) of the Mini-Mental State (MMS) for the detection of cognitive impairment (CI) in Primary Care (PC) and to determine the best conditions of use for that purpose.DesignPooled analysis of two prospective, double blind, studies on the evaluation of diagnostic tools with complete verification that were conducted in Madrid and Granada (Spain).SettingThe MMS was administered in PC and the final cognitive diagnosis (gold standard) was made in Specialized Care.ParticipantsSubjects with cognitive complaints or suspected of having CI were consecutively recruited in the PC clinic.Principal MeasuresThe DA of the MMS was evaluated using the area under the receiver operating characteristic (ROC) curve (AUC). The best cut-off point was selected according to the ratio of cases correctly classified (RCC) and to the kappa index. Direct (MMSd) and age- and education-adjusted (MMSa) total scores were analyzed separately.ResultsIn the total sample of 360 subjects (214 CI), the DA of the MMSd was significantly superior to that of the MMSa (0.84±0.02 vs 0.82±0.02, p≤.001). The yield obtained by the best cut-off point of the MMSd (22/23) was modest (RCC 0.77, kappa 0.52±0.05) and was not improved by any MMSa cut-off point.ConclusionThe DA of the MMS for detection of CI in PC was modest and did not improve with adjustment of the score by age and education. The best cut-off point was 22/23, inferior to the usually recommended cut-off.Copyright © 2013 Elsevier España, S.L. All rights reserved.
