In 2017, all IMPACTT investigators experimented in coordinated manner on multifacet intervention program, proposed by the present research protocol, with 2 teams from healthcare units from the PDL region. This experiment followed collaborative work aiming to raise team awareness on task interruptions. Given the existing data in the literature, the investigators hypothesise that the implementation of a multifacet program focusing on interactions within a team could enable the percentage of task interruptions linked to interactions between coordination functions and healthcare provision activities to be decreased by 33%. This decrease would concern task interruptions that are avoidable, in order to improve healthcare safety and teamwork.

Also, the main objective of this project is to measure the impact of a program on the evolution of the characteristics of avoidable task interruptions. The project combines quantitative data (observations, questionnaire) and qualitative data (interviews).

This research is a controlled, randomised, blind, pragmatic intervention study (36 months). From the list of volunteering teams meeting inclusion criteria, a random selection will be made. This will enable the formation of two groups of 20 teams each (control group and experimental group). An observational method coupled with a validated questionnaire transfer will allow teams to be questioned about their avoidable task interruptions (control group and experimental group).

The multifacet intervention program is based the concept of teamwork implementation. Targeting potential for improvement will be decided and implemented by each team (experimental group).

Statistics analysis will be conducted on teams before and after the implementation of the program. The assessment criteria will be: the evolution of characteristics of the task interruptions observed (interactions between coordination functions and care delivery functions, prevalence, avoidability, duration, resumption of tasks, social representations of task interruptions).

Inclusion Criteria:

• volunteering healthcare teams from healthcare centres in the PDL region,
• public and private legal statuses;

• including 50 professionals at the most,
• including at least the following professional categories: medical, paramedical, administrative, managerial and medical-technical/psycho-social.

Exclusion Criteria:

• Healthcare teams who do not belong to a healthcare unit in the PDL region
• Healthcare teams who do not work in a medical and/or surgical hospitalisation unit.
• Paediatric healthcare teams
• Teams that have already been subjected to a methodological support program from one of the co-investigating units on how to manage task interruptions,
• Teams that do not meet the criteria for commitment to the multifacet program
• Teams of more than 50 members
• Teams who do not include the following professional categories: medical, paramedical, administrative, managerial, medical-technical/psycho-social.
