Evaluación de la prueba de la moneda peruana en el tamizaje de trastorno cognitivo en adultos mayores

Objectives. To evaluate the Peruvian adaptation of the money test (Eurotest) for identifying cognitive impairment among >60-year-old adults. Materials and methods. This is a phase I study of diagnostic test, with a convenience sampling and calculation of the test´s sensitivity and specificity, based on a pretest prevalence of 50%. The criteria of the Diagnostic and Statistical Manual of Mental Disorders (DSM IV) and Global Deterioration Scale (GDS) were used for the operational definition of patients with cognitive impairment. Receiver operating characteristic (ROC) curve analysis was used to identify the optimal cut-off value. Results. The study evaluated 42 cases and 42 controls; there was no significant difference between age (77.88 ± 6.01 years vs. 6.49 76.14 ± years) and years of education (13.69 ± 3.70 years vs. 8.17 ± 4.71 years). The Peruvian version of the Eurotest has a sensitivity of 90.5% and specificity of 83.3% with cut-off value of 24. Conclusions. The Peruvian adapted version of the Eurotest, called prueba de la moneda peruana could be useful in screening for cognitive impairment among older adults.
