Barriers, facilitators, and implementation strategies for the initiation of Child Death Review system in Japan: a modified Delphi method study.

Background: To further curb preventable child deaths, some countries have implemented Child Death Review (CDR). CDR is a comprehensive multidisciplinary process that investigates, reviews, and registers all child deaths to consider prevention strategies. This study deciphered the barriers, facilitators, and implementation strategies in Japan.
Methods: This study used a three-round modified Delphi method. The expert panel consisted of local government officers and health professionals responsible for the CDR pilot project in Japan. As a modification, the initial list of barriers, facilitators, and implementation strategies to address each barrier and facilitator was prepared based on project reports and interviews with local government officers. Throughout the three rounds, the panel evaluated predefined barriers and facilitators, suggested and evaluated additional items, and appraised the potential effectiveness of the implementation strategies on barriers and facilitators which they were meant to address. The importance of barriers and facilitators, and the potential effectiveness of implementation strategies were evaluated using 5-point Likert scale. The priority of the combinations of barriers, facilitators, and implementation strategies were determined considering their importance and effectiveness.
Results: A total of 31 experts participated in the panel. Response rates were 96.8%, 80.6%, and 90.3% for the first, second, and third rounds, respectively. A total of 13 barriers, eight facilitators, and 72 implementation strategies corresponding to the barriers and facilitators reached consensus. At the national government level, a barrier-strategy combination of "lack of legislation (barrier)" and "legislation for CDR (strategy)," and a facilitator-strategy combination of "good multi-agency collaboration (facilitator)" and "official notices from the national government (strategy)" were at the highest priority. At the local government level, combinations of "lack of legislation (barrier)" and "constant budget allocations (strategy)," "lack of legislation (barrier)" and "citizens' acceptance (strategy)," and "good multi-agency collaboration (facilitator)" and "appointment of a full-time staff (strategy)" were at the highest priority.
Conclusion: This study demonstrated that legislation is the key to better implementation of CDR in Japan. Legislation can address various barriers such as personal information collection, multi-agency collaboration, high workload, and budget instability. Without legislation, careful strategies must be taken to solve difficulties caused by its absence.
