Does Chronic Kidney Disease-Induced Cognitive Impairment Affect Driving Safety?

Area of Science:

• Nephrology
• Neurology
• Transportation Safety

Background:

• Chronic kidney disease (CKD) is known to cause cognitive impairment.
• Cognitive deficits can significantly impact driving safety.
• The relationship between CKD and driving safety remains under-investigated.

Purpose of the Study:

• To investigate current national medical guidelines and research literature concerning CKD and driving safety.
• To assess the extent of knowledge regarding CKD's effects on driving capabilities.

Main Methods:

• Searched Medline, CINAHL, PEDro, and Scopus databases up to August 2017.
• Reviewed national driving guidelines and provincial/territorial transportation ministry information in Canada.

Main Results:

• Limited research exists, with few studies on driving fitness in CKD patients, especially in early stages.
• Studies indicate a substantial percentage of hemodialysis patients are uncomfortable driving or involved in motor vehicle collisions (MVCs).
• Existing national guidelines and driving forms inadequately consider kidney disease when assessing medical fitness to drive.

Conclusions:

• Driving safety in CKD patients is poorly understood.
• Available evidence suggests a significant risk of unsafe driving among CKD patients.
• Further research is crucial to understand CKD's impact on cognitive function and driving risk.
