2020 JAPAN Critical Limb Ischemia Database (JCLIMB) Annual Report

Area of Science:

• Vascular Surgery
• Clinical Databases
• Patient Outcomes

Background:

• Critical limb ischemia (CLI) management requires comprehensive data.
• The Japanese Society for Vascular Surgery initiated a nationwide CLI patient registry in 2013.
• Understanding current CLI treatment practices is crucial for improving patient care.

Purpose of the Study:

• To establish the JAPAN Critical Limb Ischemia Database (JCLIMB) for nationwide CLI patient tracking.
• To clarify the current status of medical practice for CLI patients.
• To improve the quality of medical care for individuals with CLI.

Main Methods:

• Data collection via the National Clinical Database (NCD).
• Registration of patient background, therapeutic measures, and prognosis (up to 5 years).
• Inclusion of conservatively managed limbs alongside surgical and endovascular treatments.

Main Results:

• In 2020, 1299 CLI limbs were registered by 85 facilities.
• Males constituted 69% (890 limbs) of the registered cases.
• Arteriosclerosis obliterans was the cause in 99% of registered CLI limbs.

Conclusions:

• The JCLIMB database provides valuable insights into CLI patient demographics and treatment.
• Early prognosis data from the registry can inform clinical decision-making.
• Continued data collection is essential for advancing CLI management strategies.
