Evidence for your Practice: Is the Quick Mild Cognitive Impairment Screen (QMCI) more accurate at detecting mild cognitive impairment than existing short cognitive screening tests?

Article: Glynn, K., Coen, R., & Lawlor, B. (2019). Is the Quick Mild Cognitive Impairment Screen (QMCI) more accurate at detecting Mild Cognitive Impairment than existing short cognitive screening tests? A Systematic review of the current literature. International journal of geriatric psychiatry.

Study Aim: 

To conduct a literature review to compare the accuracy, sensitivity, and specificity of the QMCI at differentiating normal cognition, mild cognitive impairment (MCI), and dementia to existing short cognitive screening tests at their optimal cut‐off scores.

Key Findings:

• Pooled data showed the QMCI has superior sensitivity, specificity, positive, and negative predictive values to the MoCA and SMMSE at detecting cognitive impairment
• The QMCI has better sensitivity and specificity at differentiating MCI from dementia than the SMMSE but a marginally lower sensitivity than the MoCA

Bottom Line for OT:

• Based in the current review, the QMCI represents a more accurate, sensitive, and specific screening test for MCI and dementia than the SMMSE or the MoCA
