Correlation Between Capillary Refill Time and Perfusion Index in Critically Ill Patients

Assessment of capillary refill time (CRT) is a cornerstone of tissue perfusion monitoring in critically ill patients. CRT measurement is performed by applying brief and gentle pressure (for a few seconds) to a small area of skin until blanching occurs. CRT is defined as the time, in seconds, required for the skin surface to return to its initial color after release of pressure. Although CRT is a monitoring tool used on a daily basis in emergency departments and critical care units, its practical measurement modalities remain poorly standardized and time-consuming. Consequently, there is no consensus regarding the most reproducible bedside method for CRT assessment. Moreover, repeated CRT measurements during patient management are resource-intensive in terms of medical time and may raise issues related to healthcare staff availability. The perfusion index (PI) is a marker of tissue perfusion derived from a pulse oximetry sensor. This monitoring device is routinely used in all critically ill patients. It is placed on the finger and worn continuously, including during patient transport. Because PI measurement is automatic and continuous, establishing its correlation with CRT could allow for more precise tissue perfusion monitoring while reducing the time burden associated with bedside assessments in critically ill patients.

Continuous Monitoring of Patients in and After the Acute Admission Ward to Optimize Clinical Pathways

Hospitals aim to hospitalize patients when necessary and discharge patients when possible. However, the triage process and discharge management of patients in e.g. the Acute Admission Ward, is not a trivial task. The upcoming technology of wearable monitoring devices, whereby patients can be continuously monitored with an unobtrusive vital signs device, might help getting more insight into patients' health condition and thus help facilitate efficient and effective triaging. Therefore, the primary objective is to assess the effects of continuous monitoring of patients in the acute admission ward (AAW) on the percentage of patients who can be discharged home. Secondary objectives are to assess the length of stay in the acute admission ward and in the in-hospital wards, as well as the effect on admission to the intensive care unit, rapid response team calls and hospital readmission. The predictive value of algorithms applied to the monitoring data combined with other parameters to detect timely deterioration and predict discharge will be assessed. Facilitators and barriers for implementing such a system will be investigated.

Non-contact Patient Monitoring With Millimeter Wave Radar Technology.

This study aims to develop a millimeter wave radar technology-based patient monitoring system that allows for the monitoring of physiological and movement-based data in healthcare settings without requiring physical contact with individuals. The study will involve the creation of hardware and software components for processing, analyzing, and converting signals obtained through radar sensors into clinically meaningful data.

Home Monitoring in Hemophilia A

Rationale: A novel point-of-care device capable of measuring factor VIII (FVIII) activity and thrombin generation (TG) is currently under development. Utilization of this device in a home situation could potentially transform hemophilia care and improve patients' autonomy. Objective: To explore the potential consequences of home monitoring of hemostatic parameters in patients with hemophilia A Study design: Cross-sectional observational study consisting of semi-structured interviews and focus groups Study population: Approximately 10 patients treated with vitamin K antagonists engaging in self-monitoring of coagulation at home and approximately 20 patients with hemophilia A. Main study parameters/endpoints: The main outcome of this study is to assess series of interrelated themes related to the unmet needs of hemophilia patients and the envisioned potential consequences of home monitoring on these unmet needs. Secondary outcomes include: identifying key features of a home monitoring platform to be used in hemophilia care, describing the experienced consequences of implementing home self-monitoring in anticoagulation treatment, assessing the current experiences of patients with self-monitoring, and providing an overview of the burdens and unmet needs experienced by patients with hemophilia with current hemophilia care. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The risk associated with participation in this study is negligible. Minor patients will be included in this study only if informed consent is given by both the patient and his/her caregiver (in patients between 12-16 years old). Gathering the insights of caregivers of minor patients on the current care for hemophilia and potential consequences of home self-monitoring is vital, as their experiences and needs might differ significantly from older patients. Participating in this study does not entail direct benefits. However, patients who participate can contribute to the development of future monitoring systems, which have the potential to alleviate the current burden of their disease and treatment.

Anatomical Landmark Method for Paediatric Port Catheter Tip Positioning

This study looks at how to place port catheters safely and accurately in children who need long-term intravenous treatment. For these treatments to work well and to avoid problems such as heart rhythm issues, blood clots, or infections, the tip of the catheter must be in the correct position inside a large vein near the heart. Doctors commonly use two different methods to estimate the correct catheter length. One method uses body measurements and surface landmarks on the chest. The other method, called intracavitary electrocardiography (IC-ECG), uses changes in the heart's electrical signal during the procedure to guide placement. In this study, researchers compared these two methods in children. They measured how closely the results of the two techniques matched and how much they differed. After the catheter was placed, chest X-rays were used to check whether the catheter tip was in the correct position. The goal of this study is to determine whether the simpler anatomical method can provide accurate and clinically reliable results compared to the IC-ECG method.

ESOTIP-TEE: Defining an Easy Landmark to Guide Correct Esophageal Probe Placement With Transesophageal Echocardiography

This prospective observational study aims to identify simple external anatomical landmarks that allow reliable prediction of correct esophageal probe insertion depth. Accurate placement in the lower third of the esophagus is essential for reliable core temperature monitoring. Transesophageal echocardiography (TEE) will be used as the reference standard to confirm correct probe position. The study will evaluate the agreement between landmark-based insertion depth and TEE-confirmed placement in adult ICU patients undergoing clinically indicated TEE.

Evaluation of the viQtor Monitoring Solution on Surgical Wards

The REQUEST study aims to evaluate the use of a new wireless monitoring device, called the viQtor solution, on a surgical ward in Catharina Hospital Eindhoven. This device continuously tracks vital signs, such as heart rate, breathing rate, and blood oxygen levels, in patients after surgery. The goal is to see if the viQtor solution can help detect health problems earlier and reduce the workload for nurses by minimizing the need for manual checks. The study will involve 500 patients and will take place over 7 months.
