Abstract

The need for standard endovascular neurosurgical (ENS) training programs and certification in Korea cannot be overlooked due to the increasing number of ENS specialists and the expanding ENS field. The Society of Korean Endovascular Neurosurgeons (SKEN) Certification Committee has prepared training programs and certification since 2010, and the first certificates were issued in 2013. A task force team (TFT) was organized in August 2010 to develop training programs and certification. TFT members researched programs and systems in other countries to develop a program that best suited Korea. After 2 years, a rough draft of the ENS training and certification regulations were prepared, and the standard training program title was decided. The SKEN Certification Committee made an official announcement about the certification program in March 2013. The final certification regulations comprised three major parts: certified endovascular neurosurgeons (EN), certified ENS institutions, and certified ENS training institutions. Applications have been evaluated and the results were announced in June 2013 as follows: 126 members received EN certification and 55 hospitals became ENS-certified institutions. The SKEN has established standard ENS training programs together with a certification system, and it is expected that they will advance the field of ENS to enhance public health and safety in Korea.

INTRODUCTION

Endovascular neurosurgery (ENS), intravascular neurosurgery and interventional neuroradiology have become major treatment modalities for cerebrovascular diseases along with neurosurgical operations. Despite gradual advances in noninvasive neurodiagnostic technology, diagnostic cerebral catheter angiography is still recognized as the gold standard for evaluating cerebrovascular diseases4). However, all ENS procedures carry a risk for stroke, indicating that appropriate and acceptable knowledge, procedural training, and case experience are necessary to perform ENS procedures safely. While several other countries have suggested ENS training standards1,3,4,7,9,10,14,15,17,19) or have begun ENS certification, no ENS training programs or certification systems have been established in Korea. There are two ENS-associated societies in Korea; The Society of Korean Endovascular Neurosurgeons (SKEN) and the Korean Society of Interventional Neuroradiology. The need for standard ENS training programs and certification in Korea cannot be overlooked due to the increasing number of ENS specialists and expanding ENS fields. The SKEN Certification Committee has prepared training programs and certification since 2010, and the first certificates were issued in 2013. The purpose of this study was to introduce training standards and define the minimum training and case experience required for certification.

PREPARATION OF THE TASK FORCE TEAM AND CERTIFICATION COMMITTEE

A task force team (TFT) was organized in August 2010 to develop training programs and certification. TFT members conducted research on programs and systems in other countries1,2,3,4,5,6,8,9,10,11,12,13,14,15,16,17,18,19,20,21) and conceptualized the programs that would best suit Korea. After 1 year of effort, a rough draft of the ENS training and certification regulations was prepared, and the standard training program title was decided. The certification comprises personal certification, hospital certification, and training-facility certification. The first briefing meeting was arranged for the executive directors of the SKEN in August 2012. The TFT emphasized the need for standard training programs and certification, and it was decided to introduce the training programs and certification. The TFT felt the need for more information on the current ENS situation in Korea before prescribing detailed rules; thus, they conducted a questionnaire survey of all SKEN members. This enabled the TFT to gather informative data such as hospital capacities, case experience, ENS constitution, and disease distributions. Then, detailed rules were discussed based on the survey results and regulations in other countries1,3,4,6,9,14,15). Much effort was put into designing a program that best suited Korean society, and it took 20 months to complete the final draft. This draft was approved by the executive committee at the second briefing meeting and they resolved to form a Certification Committee. After the meeting, the TFT published a report entitled "Research Results of Korean Neuroendovascular Surgery Standard Training and Certification Program". The first meeting of the Certification Committee was held in November 2012, and detailed plans to introduce ENS certification were discussed. The certification regulations were amended several times in the course of subsequent meetings. The Certification Committee officially announced the certification program in March 2013, and applications for certification were accepted for 8 weeks. The applications were then evaluated for 3 weeks, and the results were announced in June 2013 as follows : 126 ENS members received personal certificates and 55 hospitals received hospital certificates.

THE MAIN ISSUES IN SKEN CERTIFICATION

Some patient-safety issues were discussed among the committee members at the time of developing the certification system : "How can we prove whether SKEN members are capable of performing endovascular treatment?", "What would be sufficient endovascular procedural experience for trainees?", "Are most endovascular procedures performed under an operative neurosurgical back-up system?"
As the ENS field in Korea has been expanding, the number of ENS specialists has also been increasing. Unfortunately, secure ENS procedures and units could not be guaranteed, as the SKEN did not have standard training protocols or minimal requirements for ENS units. Hence, the Certification Committee included minimum requirements for safe ENS in the regulations and essential structural elements for ENS units. Additionally, the following aspects were considered important : number of ENS cases (associated with operator skill), types of ENS, and presence of an open neurosurgery backup.
Controversy arose among the Certification Committee when the adequate number of ENS cases for certified trainees was to be decided, as standard foreign training programs and certifications did not fit the Korean situation1,10,15,18). Moreover, the committee did not have a clear picture of the Korean ENS training situation, since ENS training was conducted at each hospital with no common training protocol or certification process. The Certification Committee had several meetings to analyze the foreign systems and conduct a survey. The appropriate number of ENS cases for trainees was established based on these analyses and research.
ENS offers immediate advantages over microscopic neurosurgery, as it is less invasive and provides more rapid recovery for patients. Because the number of neurosurgeons who choose to subspecialize in ENS is increasing, the number of hospitals in which only ENS is available, with no open neurosurgery backup, is also increasing. This allows hospitals to have simpler surgical setups, thereby reducing costs. However, this also means that the number of hospitals at which neurosurgical operations are not available when needed is increasing. Therefore, the committee decided that for patient safety, which is the top priority, certified ENS hospitals should be equipped with a neurointensive care unit and microscopic neurosurgical setup.
The Certification Committee agreed that more stringent rules should be applied to certification of training hospitals because they are operated based on an authorized and reliable ENS training program. Therefore, the committee decided that certified training hospitals should be fully equipped with more facilities, cases, types of diseases, and medical staff than required for certified ENS hospitals. Moreover, evaluation standards for ENS training directors were developed with reference to foreign standards. These criteria were designed to be as practical and clear as those in other countries and to be suitable for Korean society.
