A migration driven by the need to modernise the HIS

Against a backdrop of changing regulatory requirements and healthcare practices, healthcare organisations must adapt their information systems to better organise their operations and streamline patient pathways. The Billiers Psychosocial Rehabilitation Centre has embarked on this transformation by migrating its Osiris EPR to WebHospital.

This project forms part of a wider initiative aimed at simplifying an application environment that has become complex and at providing a single tool capable of centralising administrative and medical information. The aim is to improve coordination between teams and ensure a more reliable flow of information.


A fragmented information system prior to migration

Prior to the migration, the information system was based on several separate solutions, with data exchanged via files. This approach required regular manual processing and checks, which made it difficult to track information.

This structure limited the ability to obtain a consolidated view of the patient journey and to share information seamlessly.

    We had tools that operated independently of one another, with data exchanged via files. This required a great deal of checking and coordination to ensure that the information was consistent. In practice, this added complexity to the teams’ day-to-day work.

Choosing WebHospital to standardise processes

The decision to migrate to WebHospital was driven by the aim of integrating the information system. The organisation wanted a single environment capable of meeting both administrative and medical needs.

The solution’s web-based architecture and user-friendliness were key factors in this choice, particularly in terms of helping healthcare professionals get to grips with the system.

This choice is part of a wider effort to adapt tools to day-to-day practices and simplify their use.

  • Juliette Liquier Billiers
    We’ve paid close attention to usability because it’s a key factor in getting teams on board. Using a web-based tool with more intuitive functionality is better suited to current practices. This makes it easier to get to grips with, particularly for professionals who weren’t necessarily comfortable with the previous tools.

A structured project with dedicated support

The migration was planned with the aim of going live at the start of the calendar year, requiring rigorous management and precise organisation of the various stages.

The project was managed through close internal coordination with the Evolucare teams. Support was organised around a dedicated project manager and regular progress meetings.

  • Philippe Chatelais Billiers (1)
    We needed a clear framework to move forward. Having regular meetings and a designated point of contact enabled us to structure the project and monitor progress step by step. This made decision-making and coordination between the teams easier.

  • Juliette Liquier Billiers
    What was important was being able to discuss the issues that arose easily. We were able to ask questions, understand the implications of our choices, and make adjustments as we went along. This helped to ensure the project’s success.

    The success of the project depends on clear organisation, planning ahead for each stage and regular communication with the teams to adjust settings and support users.

Limited data recovery to rebuild a consistent database

As part of the migration process, the organisation chose to limit data migration to essential administrative details, such as patient identities and movements. Medical data, prescriptions and referrals were not migrated.

This approach is part of a drive to rebuild the data architecture in line with the organisation’s developments, rather than simply replicating an existing history.

Juliette Liquier explains:

The organisation has changed significantly in recent years, both in terms of its activities and its structure. We therefore considered whether it was appropriate to continue using data that no longer necessarily reflected the way we currently operate. We decided to start afresh on a basis tailored to our current practices.

This decision involved the medical teams re-entering the information at the start of the process, supported by training initiatives to facilitate the transition.

Changes observed in patient care practices and follow-up

After several months of use, the teams report that staff are gradually getting to grips with WebHospital. The web-based interface and user-friendly design make it easy to get started, particularly for new staff.

Among the developments observed, the introduction of a patient diary allows staff to view patients’ activities and attendance throughout the day.

Philippe Chatelais explains:

We needed a tool that would enable us to track patients’ daily activities in practical terms. Now, we have the insight we need to help teams organise themselves more effectively and share information more seamlessly.

Centralising data also makes it possible to consider using it in management tools, with a view to gradually expanding its applications.

DPI migration: what lessons can institutions using Osiris learn?

The migration from Osiris to WebHospital at the Billiers Psychosocial Rehabilitation Centre illustrates the key stages of a hospital information system transformation project, from simplifying the application environment to structuring data and usage. The feedback highlights the importance of an initial scoping phase, clear decisions regarding data migration, and ongoing support for teams throughout the project.

For institutions still using Osiris, this project provides concrete insights into the conditions for implementing a migration to WebHospital, as well as the organisational impacts and necessary adjustments. It also demonstrates how teams can gradually adopt the tool and the potential developments in patient monitoring and activity management.

The Billiers Psychosocial Rehabilitation Centre is a specialist psychiatric facility focused on psychosocial rehabilitation. It supports patients through inpatient and outpatient services, integrating therapeutic, social and vocational aspects.

The centre has undergone significant organisational changes, with the development of new activities and a gradual transformation of certain care pathways.

These changes have led to a rethinking of digital tools in order to better structure patient pathways and the associated data.

A tried-and-tested deployment method

Webhospital

The roll-out of WebHospital is based on a structured and phased approach: analysing real-world usage, establishing clear project governance, configuring the system to suit working practices, training teams and providing ongoing support.

This approach ensures that each stage is managed effectively, encourages user buy-in and embeds new practices within healthcare organisations on a long-term basis.
