The AMPEL-CDSS is a clinical decision support system in routine care. We focus on increased patient safety and improved diagnostics by harnessing the potential of digital medicine.

This project was funded with tax revenues based on the budget adopted by the members of the Saxon State Parliament (eHealthSax 2018-2022).


Through the AMPEL-CDSS, medical decision-makers are supported in their work to provide patient care through improved availability and automatic prioritisation of medical information.

Funding, €2.6 million from public funds in accordance with the budget passed by the Saxon state parliament (eHealthSax), 2018-2022

Ensuring the necessary medical consistency through algorithm-based quality assurance

The core element of the project is the reporting system, which alerts within seconds if there are indications of acute clinical patterns and delays in further diagnosis and treatment. The basis for this is a complex data combination of laboratory medical results and data from the hospital information system.

Starting in 2020, the software was activated at three hospitals. In addition to the tertiary care center, Leipzig University Hospital, two standard care hospitals, the Muldentalkliniken in Grimma and Wurzen, and thus a total of more than 1500 beds are connected to the AMPEL-CDSS. Thanks to the randomized implementation, important scientific evidence on the benefits of clinical decision support systems (CDSS) can be collected.

Support for economic efficiency


Improvement of Clinical Care

The developed telemedical solution automatically forms links in real time to additional patient-related clinical information from the hospital’s patient information system on the basis of laboratory medical findings.

Alert in case of Delayed or Inadequate Therapeutic Action

If possible delays or deviations are indicated, a medical reporting system is immediately activated to ensure the necessary steps are taken on short notice in the dialogue between the laboratory physician and the responsible practitioner.

Patient Safety Enhancement

In order to increase patient safety, the system monitors and reports in real time whether medically appropriate consequences and follow-up examinations were conducted in a timely manner.

Interpretation Aids for Particular Constellations of Findings

The telemedical solution uses the quality-assured laboratory medical diagnostics to provide information regarding the presence of specific clinical patterns and analyses within seconds (“real time”) whether the correct consequences and follow-up examinations have been derived from the requested laboratory values.

Development of Regulatory Frameworks

The rules and regulations used in the AMPEL-CDSS are based on decision trees that critically consider current literature, as well as retrospective analyses of results from routine laboratory medical diagnostics. New machine learning models are being researched, validated and implemented using external datasets and expert knowledge.

Transferability of the results

The AMPEL-CDSS should also support smaller hospitals in patient care. Laboratory medical findings are ideally suited for this purpose, since their high quality and good comparability, even between different medical laboratories, already represent a promising starting position for suitable clinical decision support systems.

Documentation of Findings and Diagnoses

The results of the laboratory medical reporting system are collected for each patient case over the entire inpatient stay. Together with other notable laboratory medical findings, they will be transferred in a suitable form from the IT system to the physician’s letter within the scope of patient discharge management.

Medical Coding of Findings and Diagnoses

The software retrospectively analyses the final documentation of clinical cases and facilitates the consideration of relevant coding and billing aspects. Not only is this of great economic importance, especially from the point of view of billing with health insurance companies, but it also provides data that can be used for a retrospective evaluation of the treatment process.


The Institute of Laboratory Medicine, Clinical Chemistry and Molecular Diagnostics (ILM) at Leipzig University Medical Center (UML) is one of the leading laboratory medicine institutes in Germany. Within the scope of patient care, around 1,500 patient examinations with a total of around 20,000 laboratory-medical analyses are carried out daily for the clinic, faculty and the Medical Care Center (MedVZ) of the UKL. The ILM is accredited according to Directive 98/79/EC and DIN EN ISO/IEC 17025, as well as Directives 93/42/EEC, 90/385/EEC and DIN EN ISO 15189. The range of services includes clinical chemistry, hematological diagnostics, hemostaseology, immune and cerebrospinal fluid diagnostics, endocrinological diagnostics as well as molecular and special diagnostics.

In addition, as the Screening Center Saxony, the Institute, together with the Dresden site, provides about 50,000 newborn screening examinations for inborn errors of metabolism annually for the Free State of Saxony and Thuringia. Research at the ILM includes metabolome and protein analysis, as well as molecular and genetic research into vascular diseases and metabolic disorders. The institute also has its own department for the performance of laboratory analytics of clinical studies. There are research collaborations with numerous national and international cooperation partners from research and science. In this context, the ILM also acts as an important partner for major study projects such as the LIFE study (Leipzig Research Center for Civilization Diseases) and the medical informatics initiative of the German Federal Ministry of Education and Research SMITH (Smart Medical Information Technology for Healthcare).

Leipzig University Hospital (UKL), together with the Faculty of Medicine, looks back on a rich tradition as the second oldest university medical center in Germany. Today, with around 1,450 beds, the hospital has one of the most modern structural and technical infrastructures in Europe. More than 400,000 inpatients and outpatients are treated here annually at the highest medical level. These benefit from the innovative research power of the scientists, as the latest findings from medical research are quickly and securely transferred into medical practice here.

Muldental Clinics Inc. (non-profit) is the reliable healthcare partner for the people and communities in the Leipzig district. Over 950 employees ensure around-the-clock regional basic and standard care with the disciplines of surgery, internal medicine, gynecology / obstetrics and pediatrics and adolescent medicine with a total of 355 planned beds – ISO-certified and at the cutting edge of research. In addition, the Muldentalkliniken offer recognized special services in hand surgery, tumor surgery and therapy, thyroid surgery and palliative medicine.

The Muldentalkliniken GmbH has its headquarters in Wurzen. The non-profit company of Muldentalkliniken includes the two traditional hospitals in Grimma and Wurzen, the medical care centers (MVZ) in Colditz, Wurzen and Grimma as well as the retirement home company Muldental gGmbH in Wurzen and Brandis. The sole shareholder of the municipal company, which has been successful since 1997, is the district of Leipzig.

Founded in 2007, Xantas AG is an SME that develops software for data analysis in hospitals. The software development center is located in Leipzig. XANTAS mainly produces the software solution VISMEDICA, which is now in use at more than 100 hospitals in Germany, Austria and Switzerland, also thanks to its modular structure. In these hospitals – with a total capacity of more than 60,000 hospital beds – the software is the sound basis for analyses in the areas of medical, surgical or financial controlling of almost 5 million annually treated outpatients and inpatients, among others.

The main focus of the software development so far was on the one hand the connection of SAP-based clinical information systems, on the other hand the creation of classical data warehouse models on the basis of a nomenclature and systematics especially developed for the health care sector. The 10 years of experience in the field of systematization in the analysis process design of a hospital enables the company to react quickly and comprehensively also to new challenges in the healthcare sector and to pursue innovative approaches.
