2019 JAPAN Critical Limb Ischemia Database (JCLIMB) Annual Report
Insights
The JAPAN Critical Limb Ischemia Database (JCLIMB) tracks critical limb ischemia (CLI) patients, revealing that arteriosclerosis obliterans is the primary cause. This national registry aims to improve CLI patient care quality.
Area of Science:
- Vascular Surgery
- Clinical Databases
- Patient Outcome Tracking
Background:
- The Japanese Society for Vascular Surgery initiated a national registry for critical limb ischemia (CLI) patients in 2013.
- The registry, JAPAN Critical Limb Ischemia Database (JCLIMB), is built upon the National Clinical Database (NCD).
Purpose of the Study:
- To elucidate the current medical practice for CLI patients.
- To improve the quality of medical care for individuals with critical limb ischemia.
Main Methods:
- Data collection on patient background, treatments (conservative, surgical, endovascular), early results, and up to 5-year prognosis.
- Registration of 1070 CLI limbs from 83 facilities in 2019.
- Analysis of background data and early prognosis of registered CLI limbs.
Main Results:
- Arteriosclerosis obliterans (ASO) was the cause of CLI in 98% of registered limbs.
- In 2019, 1070 CLI limbs were registered, with 68% affecting males.
- Early prognosis data for these limbs are reported in this manuscript.
Conclusions:
- The JCLIMB database provides valuable insights into CLI patient demographics and treatment outcomes.
- Findings from JCLIMB can guide improvements in clinical practice for critical limb ischemia management.
Abstract:
Since 2013, the Japanese Society for Vascular Surgery has started the project of nationwide registration and tracking database for patients with critical limb ischemia (CLI) who are treated by vascular surgeons. The objective of this project is to elucidate the current status of the medical practice for CLI patients to contribute to the improvement of the quality of medical care. This database, called JAPAN Critical Limb Ischemia Database (JCLIMB), is created on the National Clinical Database (NCD) and collects data of patients' background, therapeutic measures, early results, and long-term prognosis as long as 5 years after the initial treatment. The limbs managed conservatively are also registered in JCLIMB, together with those treated with surgery and/or endovascular treatment (EVT). In 2019, 1070 CLI limbs (male: 725 limbs, 68%) were registered by 83 facilities. Arteriosclerosis obliterans (ASO) accounted for 98% of the pathogenesis of these limbs. In this manuscript, the background data and the early prognosis of the registered limbs are reported. Although the registration format for the simultaneous surgery of bilateral limbs in NCD was changed to one patient and two limbs, JCLIMB still counted two patients and two limbs to eliminate discrepancy with the past annual reports.
