Technology Characteristics Predicting End User Acceptance of Smart Intravenous Infusion Pumps

Technology acceptance is an important predictor of end user technology usage. Perceptions of technology characteristics relating to usability and technical performance are particularly important to understanding user acceptance. This paper reports on the implementation of Smart intravenous infusion pumps at a tertiary care hospital. Nurse user perceptions of the technology usability (five dimensions), technical performance, and acceptance were measured one month after implementation. Overall, 42% of nurses responded positively towards accepting the pump. For 21 of 23 usability characteristics and performance questions, nurses were more likely to report neutral perceptions than positive or negative perceptions. The highest positive perceptions were for ease of learning to operate the pump and reliability of the pump. Six characteristics predicted end-user acceptance. Perceptions that the IV pump enhanced job effectiveness, made the job easier, increased safety of care, and functioned as expected predicted higher acceptance, while perceptions that alarm messages were frustrating and the pump interface was rigid predicted lower acceptance. Therefore, a new finding provided in this study is that highlighting improved patient safety when hospitals implement Smart intravenous infusion pumps may improve user acceptance of the pump.

The Individual

BACKGROUND Only a few telemedicine applications have made their way into regular care. One reason is the lack of acceptance of telemedicine by potential end users. OBJECTIVE The aim of this systematic review was to identify theoretical predictors that influence the acceptance of telemedicine. METHODS An electronic search was conducted in PubMed and PsycINFO in June 2018 and supplemented by a hand search. Articles were identified using predefined inclusion and exclusion criteria. In total, two reviewers independently assessed the title, abstract, and full-text screening and then individually performed a quality assessment of all included studies. RESULTS Out of 5917 potentially relevant titles (duplicates excluded), 24 studies were included. The Axis Tool for quality assessment of cross-sectional studies revealed a high risk of bias for all studies except for one study. The most commonly used models were the Technology Acceptance Model (n=11) and the Unified Theory of Acceptance and Use of Technology (n=9). The main significant predictors of acceptance were perceived usefulness (n=11), social influences (n=6), and attitude (n=6). The results show a superiority of technology acceptance versus original behavioral models. CONCLUSIONS The main finding of this review is the applicability of technology acceptance models and theories on telemedicine adoption. Characteristics of the technology, such as its usefulness, as well as attributes of the individual, such as his or her need for social support, inform end-user acceptance. Therefore, in the future, requirements of the target group and the group’s social environment should already be taken into account when planning telemedicine applications. The results support the importance of theory-guided user-centered design approaches to telemedicine development.

Abstract BACKGROUND Diabetic ketoacidosis (DKA) is a common clinical presentation in new and previously diagnosed paediatric patients with type 1 diabetes. In contrast to other Canadian tertiary paediatric hospitals, our center lacked a physician-endorsed evidence-informed care pathway for management of DKA. In the absence of a standardized approach to DKA, variability in patient management and outcomes were observed. This project was a quality improvement initiative that sought to develop and pilot a paediatric DKA order set. OBJECTIVES Our primary aim was to attain broad clinical uptake of the order set at our tertiary care center over a 12-month period. Secondary aims included improved standard-of-care DKA management: appropriate fluid bolus volume and maintenance rates; initial potassium management; and timely dextrose supplementation. DESIGN/METHODS A paediatric multidisciplinary collaborative was created to examine evidence for the development and implementation of a DKA order set. Implementation of the order set involved department wide education, targeted end-user education, and quarterly end-user review. A modified plan-do-study-act (PDSA) cycle guided by end-user feedback and early clinical outcomes allowed progressive order set modifications. RESULTS A retrospective chart review of fifty paediatric patients presenting to our center between April 2014 and September 2016 (pre-implementation) was compared to thirty paediatric patients presenting in DKA during the post-implementation phase (September 2016 – September 2017). There were no statistically significant differences in demographic and clinical characteristics between the groups. We achieved 83% uptake of the order set for patients presenting to our tertiary center and 67% uptake for patients transferred from peripheral centers. Improvements in DKA management included: appropriate intravenous (IV) maintenance fluid rates (20% vs. 48.3%, p=0.008), earlier administration of potassium to IV fluids (66% vs. 93.1%, p=0.006); appropriate potassium chloride dosing (40 mmol/L) to IV fluid (40% vs. 79.3%, p=0.0007) and earlier addition of IV dextrose (67.4% vs. 93.1%, p=0.009). No differences in moderate to severe hypokalemia (< 3.0 mmol/L), hypoglycemia (<4.0 mmol/L) or clinically suspected cerebral edema occurred. CONCLUSION Implementation of a DKA order set in a tertiary hospital required identification of key stakeholders, formation of a multidisciplinary team, and the development of an evaluation process. There was an observed increase in physician order set uptake and DKA management practice improvements. Future goals involve expanding the implementation and evaluation process to regional and remote centers and analyzing the impact on resource utilization.
