In recent years, the global need for clinical ethics consultation services (CECS) has increased to address ethical challenges, dilemmas, and moral distress in clinical environments. In Japan, many hospitals have introduced CECS over the past decade, but few such services work effectively because of the small number of consultations. To address this, we propose two proactive ethics consultation methods: inter-professional ethics rounds and patient note reviews. This paper provides a detailed explanation of these methods, complete with scenarios based on actual cases. These methods can make CECS ‘well-functioning’ by shifting the starting points of consultation from consultees to CECS providers. We then examine the impact and value of proactive ethics consultation as well as four critical factors for its success including attitude, positioning, and competency of proactive consultation teams. We believe our suggestions will provide valuable insights for future clinical ethics consultations and stimulate academic debate about what constitutes a ‘well-functioning’ CECS.
