“…IP usability studies, in agreement with this study, observed that the low effectiveness also leads to low efficiency in the time accomplishing a task (10,27) . It is important to note that the exclusive focus on the time for accomplishing a task, even in ICUs, can be a predictor of errors, since it can encourage users to navigate through IP interface quickly and not noticing the step by step required by manufacturers.…”

“…Normative deviations in usability studies are important indicators for the safety of interactive systems. While not avoiding all errors, they bring visibility to specific guidance for substantial improvements to the interfaces of IPs (10) .…”

“…Although IP provides reliable and effective drug administration in the hospital context, problems related to its usability are observed in literature, such as: old-fashioned devices and software, which do not meet users' needs for the complexity of medications and fluids to be administered; unsimplified manual programming, which requires a series of non-obvious keystrokes; reduced screen size, which impairs visibility; among others (9)(10) . These factors may favor the occurrence of errors during their use, which, in turn, reduce patient safety.…”

Objective: To analyze the usability of two infusion pump models in a Pediatric Intensive Care Unit. Method: This is a cross-sectional study of exploratory descriptive quantitative approach. A task was carried out in a controlled environment using infusion pump with 72 nursing staff members from August to September 2018. The Methodological Guideline for Medical Care Equipment Assessment Studies and the quality model proposed by NBR ISO/IEC 9126-1 were followed. Descriptive statistical analysis was used applying Fisher’s exact test, binomial test and Mann-Whitney test. Results: 91.7% of tasks were completed. The infusion pump-2 model was associated (p < 0.001) with operationalization, tasks accomplished with non-conformities, use of a manual calculator (measure effectiveness) and task accomplishment time (measure efficiency). Conclusion: Efficacy and efficiency measures can evidence a better context of usability of IPs and identify interaction failures with the nursing staff to be improved in care practice.

“…All the five selected best papers are convincing by their rigor and their understandable and useful way of describing their methods and the results of their research. Schnittker, et al, [6] wrote a good methodological paper with good explanations of a novel usability testing technique in conjunction with a situated Cognitive Engineering method for designing interfaces. They addressed shortcomings of previous methods -i.e.…”

SummaryObjective: To summarize significant research contributions on human factors and organizational issues in medical informatics published in 2016. Methods: An extensive search using PubMed/Medline and Web of Science® was conducted to identify the scientific contributions published in 2016 that address human factors and organizational issues in medical informatics. The selection process comprised three steps: (i) 15 candidate best papers were first selected by the two section editors, (ii) external reviewers from internationally renowned research teams reviewed each candidate best paper, and (iii) the final selection of five best papers was conducted by the editorial board of the Yearbook. Results: The five selected best papers present studies with rigorous methods, properly designed and described and are, therefore, efficiently reusable for other researches. Conclusion: Human factors and ergonomics-based interventions must be tailored to the context, but meaningful ways must be simultaneously found to generate a stronger evidence base for research and to provide efficient, easy to implement, and useful methods.

“…2 ). The advantage of such an approach is that key sedation information can be presented on a single screen, without the need to navigate a number of sub-menus as with current commercially produced pump displays, therefore reducing the mental effort required for operation [ 32 ]. Additionally, information distinct to the PMPS process is also displayed.…”

A Prototype Patient-Maintained Propofol Sedation System Using Target Controlled Infusion for Primary Lower-Limb Arthroplasty

et al. 2019

Each year, many operations in the UK are performed with the patient awake, without the use of general anaesthesia. These include joint replacement procedures, and in order to reduce patient anxiety, the supervising anaesthetist delivers the sedative propofol intravenously using a target-controlled infusion (TCI) device. However, it is clinically challenging to judge the required effect-site concentration of sedative for an individual patient, resulting in patient care issues related to over or under-sedation. To improve the process, patient-maintained propofol sedation (PMPS), where the patient can request an increase in concentration through a hand-held button, has been considered as an alternative. However, due to the proprietary nature of modern TCI pumps, the majority of PMPS research has been conducted using prototypes in research studies. In this work, a PMPS system is presented that effectively converts a standard infusion pump into a TCI device using a laptop with TCI software. Functionally, the system delivers sedation analogous to a modern TCI pump, with the differences in propofol consumption and dosage within the tolerance of clinically approved devices. Therefore, the Medicines and Healthcare products Regulatory Agency (MHRA) has approved the system as a safe alternative to anaesthetist-controlled TCI procedures. It represents a step forward in the consideration of PMPS as a sedation method as viable alternative, allowing further assessment in clinical trials.
