Abstract
Objective: To analyze the application of the Mini-Mental State Examination (MMSE) scale in cognitive assessment of elderly patients in a general ward. Methods: Elderly patients who underwent nephrosurgery and thoracic surgery between July 2015 to June 2019 were eligible for the study. A total of 713 patients enrolled and data were collected for the assessment of cognitive status. We analyzed the relationship between cognitive impairment, degree of cognitive impairment, age, and gender. Result: In the 713 cases of cognitive ability assessment by the MMSE, there was cognitive impairment in 21 (4.04%) male patients, and 10 (5.18%) female patients. In addition, the analysis of the correlation between cognitive impairment and gender showed a P value of 0.51, which was not statistically significant. In the participants age research, the average age of the patients in the cognitive normal group was 72.30±6.50 years old, and the average age of the patients in the cognitive impairment group was 78.61±6.90 years old. Their p value was <0.0001, which was statistically significant. Conclusion: There is a correlation between cognitive impairment and age. Therefore, the MMSE helps detect cognitive impairment and potential safety hazards in elderly patients. It is convenient for medical staff to take corresponding measures in time to ensure the safety of the patients.
