Objective: To evaluate and summarize the relevant evidence for the management of mild cognitive impairment in patients with Parkinson's disease, and provide evidence-based support for the development of scientific and effective management of mild cognitive impairment in Parkinson's disease. Methods: According to the "6S" model of evidence-based resources, the author systematically searched guidelines, expert consensus, clinical decision, evidence summary and systematic review on the management of mild cognitive impairment in Parkinson's disease patients from domestic and foreign guide websites, professional association websites and databases. The search period is up to December 2024. Literature quality assessment, evidence extraction and summary were conducted by two researchers trained in evidence-based systems. Results: A total of 14 literatures were included, including 6 guidelines, 5 expert consensus articles and 3 systematic reviews. The 34 evidences were summarized from 7 aspects: assessment object and time, assessment content and screening tool, risk factor management, safety management, medication management, non-drug intervention and follow-up management. Conclusion: This study systematically summarizes evidences in the field of mild cognitive impairment management in patients with Parkinson's disease, which can provide scientific reference for clinical nursing staff's practice. Nursing staff should select evidence based on the actual clinical situation and individual factors of patients to guide Parkinson's patients to improve mild cognitive impairment.
