2019 JAPAN Critical Limb Ischemia Database (JCLIMB) Annual Report.

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.

2018 JAPAN Critical Limb Ischemia Database (JCLIMB) Annual Report.

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 purpose of this project is to clarify the current status of the medical practice for patients with CLI to contribute to the improvement of the quality of medical care. This database, called JAPAN CLI Database (JCLIMB), is created on the National Clinical Database 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 the JCLIMB, together with those treated by surgery and/or endovascular treatment. In 2018, 1,145 CLI limbs (male 758 limbs, 66%) were registered by 90 facilities. Arteriosclerosis obliterans has accounted for 97% of the pathogenesis of these limbs. In this manuscript, the background data, ischemic status, treatment, and the early prognosis (within 1 month) of the registered limbs are reported.

In 2017, 1137 CLI limbs (male 760 limbs: 67%, female 377 limbs) were registered by 84 facilities. ASO has accounted for 98% of the pathogenesis of these limbs. In this manuscript, the background data, ischemic status, treatment and the early prognosis (within 1 month) of the registered limbs are reported.

Aggregated Data of JAPAN Critical Limb Ischemia Database (JCLIMB) Annual Reports from 2013 to 2016.

The purpose of this project is to clarify the current status of the medical practice for the patients with CLI to contribute to the improvement of the quality of medical care.

The limbs managed conservatively are also registered in JCLIMB, together with those treated by surgery and/or endovascular treatment. The basic and early prognostic data of CLI, registered during the four years from 2013 to 2016, have been reported as annual reports. In this paper, for the purpose of clarifying the picture of clinical practice of CLI in Japan, we have compiled these data over the past four years.
