\nWe propose that by more closely aligning interdisciplinary work in (a) numeracy education for medication dosage calculations and (b) model-driven design for medical devices that are used for delivery of medication we may help address the incident-rate in incorrect medication calculations and delivery, given that such devices commonly require the user to engage with numerical information via a digital interface. We demonstrate the use of task models as a way of supporting safe, effective and efficient delivery of medication to the patient, taking as our example the use of infusion and syringe pumps in Nursing. This work indicates a new way of facilitating knowledge transfer between numeracy education and medical device design and usage, using task models. We aim to support medical professionals’ and students’ numeracy education as well as to inform the design of medical devices based on a better understanding of the use and potential errors of medication delivery by trained professionals.  \nKey words: Task models; safety-critical systems; Nursing numeracy; syringe pumps; human-centred computing; interaction design.  \nIntroduction  \nIn the course of their work, Nurses and other healthcare professionals frequently engage with medical equipment via digital interfaces. Those interfaces typically involve activities such as entering numbers, checking that equipment is correctly calibrated, measuring and recording data, etc., and sometimes calculation. Patient safety is paramount so the stakes are high.  \nThis article outlines interdisciplinary work in progress bringing together the authors’ research interests and expertise in computer science and adult numeracy in safety-critical work contexts in order to address an important issue: how best to support safe, effective and efficient delivery of medication to the patient when that delivery involves the healthcare professional engaging with medical equipment via a digital interface?  \nOur research interests and expertise are as follows. Bowen is a Computer Science researcher informal methods and modelling for safety critical software. She has been focusing on medical devices such as syringe drivers and infusion pumps for the past seven years. She is interested in users, usability, correctness and the safety properties of medical devices. Coben is a specialist in adult numeracy  \npractices and education, especially in safety-critical work contexts, who has a particular research interest in numeracy for Nursing spanning 25 years.  \nIn the safety-critical context of Nursing, Bowen’s research has focused on: engineering interactive safety-critical systems such as medical infusion pumps and syringe drivers; seeking to ensure devices behave correctly at all times; and seeking to improve design so that devices are easier and safer to use. Meanwhile, Coben’s research has sought to identify and support the development of numeracy skills required to practise safely, effectively and efficiently, including calculating and delivering medication dosages correctly using diverse delivery mechanisms, many of which have digital interfaces. She is a member of an international interdisciplinary team investigating medication dosage calculation problem-solving (MDC-PS) .  \nWe bring together concepts of technology design (both functional correctness and usability concerns), numeracy and medication delivery competency. We consider the use of task models (outlined below) as a step towards achieving this. Our wider research seeks to address the following questions:  \n• How can we use formal models of medical devices in conjunction with task models to improve the design and devel","cbCais8ifGhYpoUp","https://ap.wps.com/l/cbCais8ifGhYpoUp","pdf",517113,22,"English","# Introduction\n## Research aim and interdisciplinary background\n## Nursing safety-critical context and key research interests\n## Research questions addressed by task models\n# Problems with medical devices\n## Common issues in device interactions","[{\"question\":\"What problem does the paper address in medication delivery?\",\"answer\":\"It addresses incorrect medication calculations and delivery, especially when healthcare professionals must engage with numerical information through digital interfaces.\"},{\"question\":\"How does the paper propose improving safety and effectiveness?\",\"answer\":\"It proposes aligning numeracy education with medical device design using task models to better understand use, errors, and required competency.\"},{\"question\":\"What example is used to demonstrate the approach?\",\"answer\":\"The paper uses infusion and syringe pumps in nursing as the example domain for demonstrating task models for safe delivery of medication.\"}]","Safety First - Combining Task Models of Medical Devices with Numeracy Skills and Technical Competence | PDF",1792066052,55]
