First in the Saiseikai Group: GaiXer Medical Agent Introduced at Saiseikai Mukojima Hospital

FIXER Co., Ltd. (Headquarters: Minato-ku, Tokyo; CEO: Kiyokazu Matsuoka; hereinafter 'FIXER') announces the launch of its generative AI service specialized for medical workflow support, 'GaiXer Medical Agent (Gaiser Medical Agent),' at Saiseikai Mukojima Hospital Tokyo (Sumida-ku, Tokyo; Hospital Director: Nobuhiro Tsukada; hereinafter 'Mukojima Hospital'), operated by the Social Welfare Corporation, Imperial Grant Foundation, Saiseikai Tokyo Branch. This implementation marks the first case within the Saiseikai Group.

Background: Saiseikai Group’s DX Initiative and Challenges in Clinical Documentation

The Saiseikai, operating over 400 medical and welfare facilities nationwide, has positioned group-wide digital transformation (DX) as a key strategic initiative to build the foundation for delivering higher-quality, advanced services.

One of the core themes of this DX drive is work-style reform in clinical settings. Nurses are responsible not only for patient care but also for extensive documentation tasks, making the reduction of their workload a critical challenge.

Among these tasks, the creation of 'nursing summaries' at patient discharge or transfer poses a particularly heavy burden. A nursing summary is a clinical document compiled from the nurse’s perspective, summarizing the patient’s course of treatment, nursing interventions, and post-discharge care needs. It plays an essential role in ensuring accurate information transfer to subsequent healthcare providers or care facilities, enabling continuous care. However, creating such summaries currently requires extracting vast amounts of data from electronic medical records (EMRs) and condensing it into concise narratives, consuming significant time.

Purpose of Implementation: Operational Efficiency and Enhanced Care Coordination at Mukojima Hospital

Under these circumstances, Mukojima Hospital identified reducing nursing summary creation time and overall documentation burden as key operational priorities to enable nurses to dedicate more time to direct patient care. The hospital also aimed to eliminate inconsistencies in documentation across staff and strengthen care coordination through standardized, high-quality records.

In evaluating generative AI as a solution to these challenges, FIXER’s proven track record in providing secure generative AI platforms for handling sensitive medical information, along with its deep understanding of healthcare and its on-site, hands-on support model, were highly valued, leading to the adoption of 'GaiXer Medical Agent.'

Streamlining Nursing Summary Creation with 'GaiXer Medical Agent'

'GaiXer Medical Agent' leverages AI to analyze clinical data and nursing notes recorded in EMRs, automatically generating a draft nursing summary in just a few minutes. This eliminates the need for nurses to start from scratch, allowing them to focus on reviewing and refining the content, thereby significantly reducing creation time.

By utilizing this service, Mukojima Hospital aims to achieve greater efficiency in nursing summary creation. Furthermore, because the AI generates text using a standardized structure, it contributes to consistent documentation quality. Ultimately, the goal is to reduce nurse workload and contribute to regional healthcare through high-quality information sharing.

The following comment was provided regarding this implementation:

"A nursing summary does more than visualize nursing practices—it plays a crucial role in reliably 'connecting' the patient’s condition, background, and the care provided to the next stage of treatment.

Many patients receiving inpatient care at our hospital require ongoing care or support beyond their discharge destination. Therefore, our perspective must extend beyond simply handing over current care, to include prevention of relapse or deterioration (i.e., preventing rehospitalization).

In practice, however, creating nursing summaries that meet these requirements has demanded considerable time to review inpatient records and reorganize information. It has been difficult to allocate this time amid shift work, while also meeting demands such as shorter hospital stays and higher bed utilization rates.

To address these challenges, we have now introduced a nursing summary creation system utilizing generative AI. This enables us to summarize daily nursing practices and their evolution in a short time. By using this system, we aim to fulfill our role as a hospital trusted by the community, ensuring that the 'baton of nursing care' is smoothly passed on through nursing summaries."
