Background: The patient monitor (PM) is one of the most commonly used medical devices in hospitals worldwide. PMs are used to monitor patients' vital signs in a wide variety of patient care settings, especially in critical care settings, such as intensive care units. An interesting observation is that the design of PMs has not significantly changed...

Background
Evidence indicates that single nucleoid polymorphisms (SNPs) of key molecules in innate immunity are related to clinical outcome of community-acquired pneumonia (CAP). Pentraxin 3 (PTX3) is a member of the acute-phase reactants superfamily and plays an important role against various diseases. The purpose of the current study was to asses...

... Background A patient monitoring system is a device that monitors a patient's condition by measuring the patient's biological data in a variety of patient care settings in a hospital and is one of the important components in an Intensive Care Unit (ICU) [1]. This device measures the patient's biological data, including invasive blood pressure, electroencephalogram (EEG), electrocardiogram (ECG), carbon dioxide (CO2) gas measurements, and transcutaneous oxygen saturation (SPO2) and provides visible and audible alarms when hazardous conditions are detected [2]. ...
Background
The poor ergonomic design of patient monitoring systems can cause user errors and patient harm. This paper presents the results of a comparative usability study based on user experience and the results of a user preference survey.
Material/Methods
We conducted a usability study of 3 patient monitoring systems: Mediana M50, Philips IntelliVue MP70, and Philips IntelliVue MX700. Thirty-nine Coronary Care Unit nurses and 19 Pulmonology and Allergy Care Unit nurses participated in this usability study. User experience was assessed with the Post-Study System Usability Questionnaire and the National Aeronautics and Space Administration Task Load Index. A user preference survey was conducted to evaluate the subjective medical device design preferences for the M50 system’s user interface.
Results
Nurses from the Coronary Care Unit recognized a higher system usability for the MP70 than the M50 (P=0.001) system, and a lower workload for the MP70 compared with the M50 (P=0.005) system. There was no significant (P>0.05) difference in perceived system usability and workload between the M50 and MX700 systems for the nurses from the Pulmonology and Allergy Care Unit. Nurses preferred to activate the arrhythmia alarms except for the ST alarms and missed the beat alarm. They also preferred having a wave freeze function, standby mode, and early warning scoring function, which provides a signal for a patient’s deterioration in health.
Conclusions
The study provides valuable data on a user interface evaluation based on user experience and preference. The outcome of this study will be helpful for designing next-generation patient monitors with improved patient safety.

Abstract Background Cognitive ergonomics design of patient monitoring may reduce human factor errors in high-stress environments. Eye-tracking is a suitable tool to gain insight into the distribution of visual attention of healthcare professionals with patient monitors, which may facilitate their further development. Methods This prospective, exploratory, high-fidelity simulation study compared anesthesia personnel’s visual attention (fixation count and dwell-time) to 15 areas of interest on the patient monitor during non-critical and critical anesthesia situations. Furthermore, we examined the extent to which participants’ experience influenced visual attention and which vital signs displayed on the patient monitor received the most visual attention. We used mixed zero-inflated Poisson regression and mixed linear models to analyze the data. Results Analyzing 23 ten-minute scenarios, we found significantly more fixations to the areas of interest on the patient monitor during critical than non-critical situations (rate ratio of 1.45; 95% CI 1.33 to 1.59; p
Emerging digital healthcare solutions (DHS) have opened wide range of opportunities for tele-monitoring and improvements in health behavior. These solutions not only help monitor health status, but also aid towards diagnosis, prevention and better management of health conditions. DHS have a broad scope in long-term care, disease management as well as addressing psychological and social needs of patients. In this chapter we discuss tele-monitoring solutions for long-term care and solutions for rehabilitation. Long-term care includes a wide range of care services for patients of varied age groups with chronic conditions or functional disabilities. Their requirements can vary from minimal help for conducting daily activities to complete care. Tele-monitoring assistance can aid self-monitoring for such patients while also being digitally connected with their health care providers. The scope of these solutions for long-term care includes addressing issues such as fatigue and anxiety, quality of life, nutrition, sleep, physical activity, etc. The advancements in rehabilitation technologies are increasingly enhancing the role of rehabilitation in building and maintaining the self-dependence and quality of life of patients. The field of rehabilitation often requires complex technologies, such as virtual reality, robotics and haptic devices. The healthcare application of these technologies revolves around providing solutions for efficient home rehabilitation, multimodal approaches for recovery, to support activities of daily living and to enhance clinical assessment. Thus, the use of emerging technologies can aid family members of apparently healthy older adults and also detect mild symptoms while relying on a user-friendly solution.
