Radboudumc is combining predictive software with continuous monitoring.If it were up to internist Bas Bredie, healthcare providers at Radboud university medical center would no longer be asking the question of what blood pressure is, but instead what kind of pattern it is following. By linking the continuous monitoring of five vital functions to predictive software, healthcare providers will be shown a risk score. By using this score, unusual trends and profiles in the course of the illness can be recognized immediately. For instance, this would allow sepsis (blood poisoning) or a long embolism to be detected early and enable more prompt medical intervention. This should lead to fewer unplanned IC intakes, better prognoses, and more rapid recovery, and in turn, improved care for the patient. Bredie: “According to our information, we are the first hospital in the world that is applying this in practice in such a way and at such a scale.”
Since the beginning of June, patients in the Surgery and Internal Medicine departments have been connected to the new system. Instead of having them measured several times per day, a small box on the patient’s wrist continuously records their five vital functions (blood pressure, heartbeat, temperature, respiratory rate, and oxygen intake.) Both patients and healthcare providers are enthusiastic about this. Patients are indicating that it enables them to ask the right questions, because it provides them with more insight into the progress of their health.
Physicians and nurses are noticing that they also interact with this information differently. They no longer look at the blood pressure, heartbeat, and respiratory frequency, but instead assess the trends in those readings and adapt their actions accordingly. For instance, as sepsis develops, heartbeat and temperature increase while blood pressure drops (see Figure 1). Since one does not spend the entire day right at the patient’s bedside and there can sometimes be eight hours between measurements, gradual changes are often only discovered later. With the new predictive software, these changes can be detected several hours sooner. It is nothing but advantageous.
Alarm for needle leakage or sepsis
By monitoring continuously, you see the change in the medical situations of the patients and can intervene sooner. You can also predict who is experiencing a positive trend and can be sent home. Internist Bas Bredie: “Currently, it still costs healthcare providers a great deal of time to review all the recorded measurements and assess them as a whole. The software that we are using now and continuing to develop takes that burden off the shoulders of healthcare providers and translates the summary of that information into a new risk score. Using this score, unusual trends in the course of the illness can be detected immediately. This allows for a decline in the health of an admitted patient to be observed or predicted sooner and enables more prompt treatment. This should lead to fewer unplanned intakes to the intensive care unit (ICU), fewer extended stays at the hospital, fewer instances of CPR, and possibly even fewer deaths among patients. Using scientific research, we are attempting to make the system more specific. For example, we will soon be getting an alarm that alerts us to needle leakage or sepsis before the patient’s condition has deteriorated, which enables us to act immediately.”
Bas Bredie and his colleague, Harry van Goor, surgeon and professor of surgical education in the Surgery department, are the initiators of the research. Van Goor: “We will learn what parameters are truly important when it comes to illness and deterioration. For instance, one of the hypotheses is that of all the vital functions, variation in cardiac rhythm serves as the best predictor of how the patient’s condition will develop. One of the things that we want to investigate is whether this is actually true and to which patient groups it applies.”
Bas Bredie is member of theme Vascular damage.
