Abstract Issue There is great need in DRCongo for adequate training sites where national public health managers and workers can discover what is means to manage complex district healthcare delivery systems in a perspective of PHC and UHC. The development of such LRHD is coherent with the national policy in DRC advocating for demonstration districts. Description of the Problem The RIPSEC has launched three sites called LRHD, two of which are rural and one urban. A specialist in the organization and management of health services, from each of the three schools of public health, supervised the development and monitoring of those LRHDs. The Provincial Supervisor was also involved. Three approaches to solving priority problems have been defined: strengthening leadership at the HD level; transform health services into a learning and research framework. We analyze the transformation process obtained in these HD. Results Transformation processes in the district went through a strengthening of the capacity of the district health teams and via a process of action-research. The results of those LRHD after 4 years were mixed: the leadership of the management teams has improved. A reflexive attitude developed which contributes to more appropriate decision-making,monitoring and evaluation.At least one hospital service and 2 health centers have been transformed according to specific problems,improving the interaction between health structures, in order to quality of care has improved, the results of action research have made it possible to resolve local health problems. RIPSEC support to Provincial Supervisor to develop their working tools to better address their functions and responsibilities. However, the documentation of these changes induced by RIPSEC was not yet systematized. No residential internship could be carried out due to operational constraints. Lessons Mentoring, through its intellectual inputs, has contributed to a dynamic of change in the HD. Key messages The basis of the strategy is the improvement of the leadership of the HD management team,reinforced by mentoring and systematic documentation of complex decisions. This program could be continued to perpetuate these fragile achievements. This experience can be used elsewhere in different contexts. But,the residential internship requires other resources.
