Project Background <\/h3>\n\n\n\n

In an age of increasing demand for healthcare, providing assistance to those who need can take an enormous toll on the healthcare provider. There is a growing importance on preserving the physical and emotional health of caregivers, and identifying strategies to identify workload to combat the toll on caregivers is rapidly gaining attention. Current strategies to measure workload vary. Studies have used surveys (e.g. NASA Task Load Index, Ashgate, 2005) to ask providers or patients their measure of stress or strain in the unit, as well as provider focus groups to ask caregivers their retrospective workload stress. Retrospectively asking providers to recall their workload stress often leads to subjectivity in the measurement of workload stress resulting in measurement errors and unreliable data (Hipp, 2020).<\/p>\n\n\n\n

There is no current method for quantifying workload stress in real time. Our proposal is to develop a device that uses an ecological momentary assessment (EMA) to quantify workload stress in the ICU. A EMA is the \u201crepeated sampling of subjects\u2019 current behaviors and experiences in real time, in subjects\u2019 natural environments\u201d (Shiffman, Stone, Hufford, 2008). <\/p>\n\n\n\n

Problem Statement <\/h4>\n\n\n\n

There is currently no method for quantifying and analyzing workload stress in the ICU setting. In order to facilitate data-driven decision-making for the purpose of minimizing workload stress, we aim to address this problem. <\/p>\n\n\n\n

      Above is our working breadboard model, which served as our first prototype. Once this was completed, we worked to translate it to a Printed Circuit Board (PCB), which is far more robust and less prone to random errors due to loose connections. <\/p>\n<\/div><\/div><\/details>\n\n\n\n

      Our first PCB had two major design flaws. First, a button was double grounded in the schematic by accident rendering it useless. Secondly, we diverted from our breadboard design by adding two decoupling capacitors as it was good practice to have them; unfortunately, these decoupling capacitors impeded our button functionality further revealing another flaw. <\/p>\n<\/div><\/div><\/details>\n\n\n\n

      Our second PCB design fixed the flaws in the first design and polished the design of the PCB. The button orientations were reorganized into a manner making all button inputs the same, we fixed the double grounded button , and removed the capacitors. Additionally, we made wire traces bigger, added screw holes to our PCB to screw into our scaffold in the project box, and made the real time clock module through-hole mounted. Now the only difference between our initial prototype and final device is the modality\u00a0 (breadboard \u2192 PCB).\u00a0 <\/p>\n<\/div><\/div><\/details>\n<\/div>\n\n\n\n
