AIQNET is a digital ecosystem for using medical data across different sectors and in compliance with data protection regulations. It focuses on using artificial intelligence to structure this data. The Siegfried Weller Institute for Accident Medicine (SWI), which is researching the correlation between secondary conditions affecting patients and their impact on outcomes, is a partner in the project, which is being funded by the German Federal Ministry for Economic Affairs and Energy (BMWi). However, AIQNET is not solely focused on collating and structuring medical and clinical data. It also aims to use AI to ensure high-risk patients are identified as early as possible and to obtain clear treatment recommendations.

Huge volumes of data are collected for medical reasons in every hospital. It is stored in various archive systems and often in an unstructured way, whether paper copies of letters from doctors or test results and laboratory findings in PDF format. AIQNET centres on using artificial intelligence (AI) for the automated procurement, structuring and analysis of this data. The overall project is being coordinated by BioRegio STERN Management GmbH, which is based in Stuttgart, while it was Leipzig-based RAYLYTIC GmbH that initiated the work and is leading the consortium.

"The objective is to identify high-risk patients as early as possible and give medics the opportunity to query risks at the touch of a button. This then makes it possible to minimise conceivable complications from surgery, and treatment is improved objectively and subjectively," explains Prof. Andreas Nüssler, director of the Siegfried Weller Institute for Accident Medicine (SWI). One of the areas being studied by the research institute - part of BG Hospital Tübingen - is the correlation between various secondary conditions affecting patients and their impact on outcomes.

The researchers are working in partnership with medtech company Aesculap AG and have chosen knee implants as the use case for AIQNET, because the link between implant risks and secondary conditions can be easily tracked. "The surgeon needs to decide which implant is most suitable for a certain type of patient," Prof. Nüssler points out. "This decision is easier to make if secondary conditions are systematically recorded. It all comes down to comorbidity. We anticipate that AI - if trained appropriately - will itself conclude, based on the collated patient data, that a particular patient has a particular problem. That could be an increased risk of malnutrition, for instance, which affects up to 25 per cent of patients, and up to 40 per cent in geriatric trauma surgery. A suitable course of action can then be devised with similar precision." After all, despite outstanding surgical technology and the best implants, patients do not all have the same recovery chances. If, for example, patients have diabetes, they are at a high risk of developing a diabetic osteopathy, which means they are at a similarly high risk of complications if they require a knee implant. "With over 10,000 operations a year at BG Hospital Tübingen, this adds up to a large number of risk factors that patients bring with them from home," says Prof. Nüssler. To date, all findings are the result of exhaustive clinical studies. AIQNET has been designed to make it easier to draw useful findings from this data.

Ethical considerations and data protection laws are crucially important to Prof. Nüssler: "Hospitals do a huge amount of work to comply with statutory regulations, operate IT security systems and explain to patients that they can make their data available. We need to make it clear to them that they themselves benefit from this the most." According to the project team, AIQNET offers an opportunity for AI to facilitate real progress in the interest of patients. That is why the digital ecosystem is reportedly one of the key projects at BG Hospital Tübingen. "We see ourselves as pioneers of cutting-edge healthcare", declares Prof. Nüssler.
