Common problems with current industry standard patient monitoring: a mixed qualitative and quantitative study
Abstract BACKGROUND: Patient monitoring ensures the safety of patients in perioperative, intensive care and emergency medicine. There are some well-studied issues, such as alarm fatigue and information presentation. For this study, we use a mixed qualitative and quantitative approach to get a global feel for the problems of users with today's state of the art patient monitoring. METHODS: First, we conducted interviews with 120 anesthesiologists (physicians and nurses) asking them about problems they experience with patient monitors. We then coded the answers into topics and subtopics that we present and discuss. In a second study, a field survey with 25 anesthesiologists, we added a quantitative part in which anesthesiologists rated their agree- or disagreement with statements based on the themes identified in the prior analysis on a five-step ordinal rating scale. RESULTS: We have identified the following six main topics: 1. "Alarms," 2. "Artifacts," 3. "Software," 4. "Hardware," 5. "Human Factors," 6. "System Factors," and a total of 17 sub-topics. The quantitative statements raised for each major theme were: 1. “problems with alarm settings complicate the work with patient monitoring.” (96% agreed) 2. “artifacts complicate the assessment of the patient's condition.” (56% agreed) 3. “information overload makes it difficult to get a quick overview of the situation.” (56% agreed) 4. “problems with cables make working with patient monitors tedious.” (88% agreed) 5. “factors related to human performance lead to patient conditions not being perceived on the monitor.” (64% agreed) 6. “Insufficient standardization: Switching back and forth between monitors from different manufacturers makes it difficult to work with patient monitors.” (88% agreed). Non-parametric testing determined all six statements to differ significantly from the neutral opinion. CONCLUSION: This study provides an overview of the problems users face in their work with patient monitoring. The most annoying issues identified were related to alarms, cables and insufficient standardization between different manufacturers. An ideal monitor should, therefore, have an alarm system that reduces false positive alarms to a minimum, works with as few cables as possible and is easy to learn. This paper shows that there is still much room for improvement in patient monitoring systems.
