Significant Dissatisfaction with the Anachronistic System: A Survey on The Experience of Application for Off-Label Use of Anti-Cancer Drugs by Korean Society of Medical Oncology.

Abstract

Purpose: This study evaluates the experiences and satisfaction levels of Korean medical oncologists with the prior authorization system for the off-label use of anti-cancer drugs. Conducted by the Korean Society of Medical Oncology (KSMO), the survey aimed to identify challenges and areas for improvement in the current regulatory framework.

Materials and methods: A cross-sectional web-based survey was carried out between May 4 and May 14, 2023, targeting 261 active KSMO medical oncologists. Invitations were sent via email, and the survey, comprising 19 questions, was hosted on Microsoft Forms. The questions covered personal characteristics, work environment, experiences with the pre-application process, and post-approval experiences.

Results: For the 261 invitations sent, 110 responses (42.1%) were received. Most respondents had over 10 years of experience and worked in tertiary hospitals. Although 93.6% were familiar with the pre-application system, 67.3% expressed moderate to high dissatisfaction. The key issues included complex applications, long approval period, stringent criteria, and inconsistent reviews. Additionally, 74.4% respondents spent over 3 hours on first-time applications, with 68.3% experiencing rejections. Emotional responses to rejections were largely negative, with many feeling disregarded. Post-approval, patients of 96.8% respondents faced financial burdens leading to treatment discontinuation. Most oncologists (86.0%) supported selective reimbursement if the disease was controlled for a certain period.

Conclusion: The survey highlights significant dissatisfaction with the current system, suggesting the need for streamlining the application process, easing approval criteria, and reconsidering the financial aspects of post-approval treatments to support patient care and oncologists' decision-making autonomy.
