Within the SNOWDROP project, we are developing a clinical decision support system for decreasing fall risk-increasing medication for general practitioners. The system predicts the individual risk of falls for the older patient based on prediction models. If a patient has a high risk of falling according to the system, the GP can call the patient for a consultation in which a medication assessment will be carried out and the fall risk will be further identified. The patient is offered information about the fall risk and medication-related treatment options via a patient portal. The patient can use this information to prepare for the consultation. During the consultation, the clinical decision support system provides support to the GP and the patient for joint decision-making about adjusting fall risk-increasing medication. The patient can view the decisions and advice discussed during the consultation in the patient portal

Model explainability and transparency are requirements in healthcare applications. This is especially important when proposing models for healthcare that consume or generate natural language inputs such as free-text clinical notes. The major trend in explainability research in artificial intelligence resorts to the post-hoc explainability of black-box models, which are methods that try to approximate how a black-box model produces their predictions. However, we would like to build models that are inherently explainable and transparent. In this project, we propose not only post-hoc explainability methods for NLP, but also NLP methods that are explainable by design.

People with multimorbidity suffer from suboptimal pharmacotherapy due to insufficient knowledge to guide prescribing decisions. Leveraging routinely collected data in Electronic Health Records (EHRs) using machine learning (ML), have been widely advocated to close this knowledge gap and provide missing insights on safety and effectiveness of drugs. However, EHR data suffer from many quality issues. In addition, there are still significant limitations in the introduction of ML models to support in prescribing decisions, due to the lack of transparency in how model outputs are generated (the "black box” dilemma), and lack of logical reasoning (models not informed by causal domain knowledge).

Therefore, LEAPfROG aims for scientific breakthrough in ML application in healthcare by addressing the aforementioned limitation and creating a medication safety learning system. A system powered by novel ML-powered tools capable to provide trustworthy and explainable causal suggestions. The value of the ssystem will be demonstrated via clinically relevant and urgent use case of drug-induced kidney diseases (DIKD) in patients with chronic kidney disease (CKD). Patients with CKD are amongst the most complex and multimorbid. By providing missing insights on DIKD in patients with CKD via PIL, LEAPfROG will contribute to safer and more effective pharmacotherapy in these patients. Aiming to increase quality of life of patients with CKD and decrease healthcare costs related to medication harm

In the ICU, 71% of the patients receive antibiotics. Of these antibiotics, 30% to 60% is prescribed unnecessary, inappropriate, or suboptimal.

Audit & Feedback is proven to be effective in stimulating quality improvement, therefore the NICE2Improve dashboard was developed. This dashboard includes actionable quality indicators and a toolbox with suggestions of improvement actions to support ICU staff on how they can increase appropriate antibiotics use. The purpose of this research is to pinpoint areas where specific ICUs might experience barriers to quality improvement, to devise a method for creating a tailored toolbox, and to evaluate the effectiveness of the tailored toolbox in enhancing antibiotic use in the ICU.

Machine learning (ML) models have made remarkable advancements in analyzing medical data, yielding impressive results. However, a significant limitation lies in their performance, which is primarily optimized for data from the training distribution and can degrade when the model is used on a different distribution. As we aim to deploy these ML models in real-world healthcare scenarios, ensuring their reliability becomes of utmost importance. Consequently, it is crucial to devise a method that can effectively detect samples that lie outside the training distribution before making potentially erroneous predictions on them. By doing so, we can proactively avoid erroneous predictions on out-of-distribution (OOD) data. 

In this project, we address this specific challenge within the context of medical tabular data. Our primary objective is to investigate and develop a robust method for identifying OOD data points in real time. By developing effective solutions to detect OOD data in medical tabular datasets, we can elevate the reliability and applicability of ML models in real-world healthcare settings. This could potentially lead to improved patient outcomes and enhanced decision-making processes, as healthcare professionals can trust the model's predictions and be alerted when encountering unfamiliar or OOD cases. Ultimately, our research aims to bridge the gap between ML advancements and practical healthcare implementation, fostering a more reliable and secure healthcare AI ecosystem.

This project is a consortium with the medical device company Pacmed and it aims at supporting the decisions of intensive care clinicians dealing with treatments of variable length. Such treatments are difficult to administer because it is hard to understand when is the optimal time to stop treatment; for instance with mechanical ventilation, it can be hard to judge when the patient can be safely extubated. The work package entrusted to KIK concerns the study of causal inference techniques to assess the effect of such dynamic treatments. These solutions will then be tested on real-world data leveraging the ongoing collaboration between Pacmed and the Santeon hospitals, enabling a quick iteration and a speedy trajectory towards the improvement of current hospital processes.

Adverse drug events (ADEs) are a major public health concern. In the Netherlands, ADEs are a leading cause of preventable patient harm in hospitalized patients, and their reduction is needed but so far unsatisfactory. Currently, information about ADE occurrence mainly comes from voluntary reporting. However, research shows that fewer than 1% of ADEs are reported in this way. ADEs are often documented by physicians in clinical notes as part of routine care, and clinical pharmacists would need to manually analyze vast amounts of clinical notes to gain a thorough insights on ADE occurrence. This is prohibitively time consuming and not future-proof. An automated method for ADE detection from clinical notes would support clinical pharmacists in their crucial role as medication safety gatekeepers. Natural language processing (NLP), a computerized approach to analyze text data, has shown promising results for the purpose of ADE detection from clinical notes. However, most NLP methods available were develop on clinical text in English.

Within the hospitalized patients, patients admitted to the Intensive Care Unit, are most prone to ADEs due use of multiple, high-risk drugs. At present, a routine identification of Adverse Drug Events (ADEs) is not available for Dutch Intensive Care Units (ICU). This hampers timely ADE detection. Especially drug-induced acute kidney injury (DAKI) presents serious concerns for ICU patients. Therefore, the main goal of the REMEDY study is to develop and validate an automated method to detect ADEs in Dutch clinical notes using Natural Language Processing (NLP).

The current best practice approach for the diagnosis of adverse drug events (ADEs) in hospitalized patients relies on a manual procedure, including a full patient chart review and a formal causality assessment by multiple medical experts. The resource intensive character of this approach, hampering large scale medication safety monitoring and use in daily, often busy, clinical practice. Furthermore, this approach also suffers from low inter-rater reliability and a high risk of bias. Novel methods for the diagnosis of ADEs are therefore urgently needed, and artificial intelligence may aid through automated, data-driven approaches. Within the hospitalized patients, patients admitted to the Intensive Care Unit, are most prone to ADEs due use of multiple, high-risk drugs. Especially drug-induced acute kidney injury (DAKI) presents serious concerns for ICU patients. Therefore, the aim of the RESCUE project is to develop and validate an automated DAKI causal algorithms for ICU patients by utilizing advanced machine learning techniques and best-practices for causal inference using observational routinely collected ICU data. If proven successful, the developed automated and data-driven approach may be applicable for any other ADEs.

For health outcomes, socioeconomic status (SES) is an important determinant. Generally, a lower SES is associated with more adverse healthcare outcomes. It is unclear whether this phenomenon is present in patients admitted to the intensive care unit (ICU), especially in The Netherlands. Therefore, this nationwide observational cohort study will investigate SES in the total Dutch ICU population and across regions, the association between SES and (hospital/long-term) mortality, and its effect on individual estimated mortality risks. Depending on the outcomes, we will try to improve the case-mix model (APACHE IV) for estimating individual mortality risks and examine its influence on benchmarking Dutch ICUs. We will use a composited (occupation, income, education) SES score per household and per postal code to identify possible differences between these scores.
