To study the utility of the Mini-Cog test for detection of patients with cognitive impairment (CI) in primary care (PC). Methods. We pooled data from two phase III studies conducted in Spain. Patients with complaints or suspicion of CI were consecutively recruited by PC physicians. The cognitive diagnosis was performed by an expert neurologist, after formal neuropsychological evaluation. The Mini-Cog score was calculated post hoc, and its diagnostic utility was evaluated and compared with the utility of the Mini-Mental State (MMS), the Clock Drawing Test (CDT), and the sum of the MMS and the CDT (MMS + CDT) using the area under the receiver operating characteristic curve (AUC). The best cut points were obtained on the basis of diagnostic accuracy (DA) and kappa index. Results. A total sample of 307 subjects (176 CI) was analyzed. The Mini-Cog displayed an AUC (±SE) of 0.78 ± 0.02, which was significantly inferior to the AUC of the CDT (0.84 ± 0.02), the MMS (0.84 ± 0.02), and the MMS + CDT (0.86 ± 0.02). The best cut point of the Mini-Cog was 1/2 (sensitivity 0.60, specificity 0.90, DA 0.73, and kappa index 0.48 ± 0.05). Conclusions. The utility of the Mini-Cog for detection of CI in PC was very modest, clearly inferior to the MMS or the CDT. These results do not permit recommendation of the Mini-Cog in PC.enAtención Primaria de SaludEnfermedad de AlzheimerDeterioro Cognitivo LevePruebas PsicológicasAndaluciaEspañaCuestionariosSensibilidad y EspecificidadHumanosMedical Subject Headings::Health Care::Health Services Administration::Patient Care Management::Comprehensive Health Care::Primary Health CareMedical Subject Headings::Diseases::Nervous System Diseases::Central Nervous System Diseases::Brain Diseases::DementiaMedical Subject Headings::Psychiatry and Psychology::Mental Disorders::Delirium, Dementia, Amnestic, Cognitive Disorders::Cognition Disorders::Mild Cognitive ImpairmentMedical Subject Headings::Psychiatry and Psychology::Behavioral Disciplines and Activities::Psychological TestsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Data Collection::QuestionnairesMedical Subject Headings::Geographicals::Geographic Locations::Europe::SpainMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Statistics as Topic::Sensitivity and SpecificityMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::Humansresearch article24069544open access10.1155/2013/2854622090-8024
