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.

Filtering Approach

Recommender System (RS) is an information filtering approach that helps the overburdened user with information in his decision making process and suggests items which might be interesting to him. While presenting recommendation to the user, accuracy of the presented list is always a concern for the researchers. However, in recent years, the focus has now shifted to include the unexpectedness and novel items in the list along with accuracy of the recommended items. To increase the user acceptance, it is important to provide potentially interesting items which are not so obvious and different from the items that the end user has rated. In this work, we have proposed a model that generates serendipitous item recommendation and also takes care of accuracy as well as the sparsity issues. Literature suggests that there are various components that help to achieve the objective of serendipitous recommendations. In this paper, fuzzy inference based approach is used for the serendipity computation because the definitions of the components overlap. Moreover, to improve the accuracy and sparsity issues in the recommendation process, cross domain and trust based approaches are incorporated. A prototype of the system is developed for the tourism domain and the performance is measured using mean absolute error (MAE), root mean square error (RMSE), unexpectedness, precision, recall and F-measure.

Abstract Objective To evaluate end-user acceptance and the effect of a commercial handheld decision support device in pediatric intensive care settings. The technology, pac2, was designed to assist nurses in calculating medication dose volumes and infusion rates at the bedside. Materials and Methods The devices, manufactured by InformMed Inc., were deployed in the pediatric and neonatal intensive care units in 2 health systems. This mixed methods study assessed end-user acceptance, as well as pac2’s effect on the cognitive load associated with bedside dose calculations and the rate of administration errors. Towards this end, data were collected in both pre- and postimplementation phases, including through ethnographic observations, semistructured interviews, and surveys. Results Although participants desired a handheld decision support tool such as pac2, their use of pac2 was limited. The nature of the critical care environment, nurses’ risk perceptions, and the usability of the technology emerged as major barriers to use. Data did not reveal significant differences in cognitive load or administration errors after pac2 was deployed. Discussion and Conclusion Despite its potential for reducing adverse medication events, the commercial standalone device evaluated in the study was not used by the nursing participants and thus had very limited effect. Our results have implications for the development and deployment of similar mobile decision support technologies. For example, they suggest that integrating the technology into hospitals’ existing IT infrastructure and employing targeted implementation strategies may facilitate nurse acceptance. Ultimately, the usability of the design will be essential to reaping any potential benefits.

Introduction Pembrolizumab is an anti-PD-1 monoclonal antibody, approved and under development for numerous indications in oncology. It is available as either lyophilized powder for reconstitution or ready-to-use solution. Both are required to be diluted in saline or dextrose solution prior to intravenous infusion. After dilution, the recommendation per summary of product characteristics is 24 h at 2–8℃ and 6 h at room temperature. The purpose of this study was to investigate the physicochemical stability of pembrolizumab diluted solution (1 mg/mL) at both refrigerated and room temperature conditions for an extended period. Methods Under aseptic conditions, pembrolizumab was diluted in 250 mL of saline injection in polyolefin bags to obtain the final protein concentration of 1 mg/mL. Thus, prepared bags were then stored at either 5℃ ± 3℃, refrigerator exposing the product to ambient light or room temperature (20℃ ± 3℃) on the benchtop. Results Using several analytical methods, it was demonstrated that pembrolizumab solution for infusion, diluted in normal saline can be stored in polyolefin infusion bags for at least 1 week at 5℃ or RT with no evidence of chemical or physical instability. No aggregation was observed. Conclusion Thus, the practical use of aseptically prepared diluted pembrolizumab in saline can be safely extended to optimize the workload of centralized preparation units and to minimize costs. However, it is the responsibility of the end-user to maintain overall quality of prepared admixture solution that is administered to patient, by following aseptic compounding process as recommended in the packaging insert.

The accuracy, safety, reliability and cost of use of 35 intravenous infusion pumps and 3 flow controllers were assessed. When infusing saline 11 out of 17 syringe pumps, 3 out of 5 peristaltic pumps, 1 out of 2 roller pumps and all 14 cassette pumps tested were accurate to within 5% over their full ranges of operation. There was no significant change in the performance of any of the pumps tested when saline was infused through a standard resistance, except in the cases of the 3 flow controllers which were unable to infuse at all against the resistance. When 50% dextrose was infused, delivery by two peristaltic pumps was reduced by 23 and 38%. No pump cut out or alarmed at pressures of up to 200 mmHg and 21 pumps continued to infuse against pressures of 750 mmHg or greater. Surges of up to 0.5 ml occurred after release of an outlet obstruction. One device was fitted with a variable high pressure alarm. This device could also measure pressure in the infused vessel and was found to be accurate for measurements of central venous pressure. The cost of consumables for a single use for syringe pumps ranges from A$2 to $5, for peristaltic and roller pumps from A$1 to $10, and for cassette pumps from A$7 to $12, with an additional A$2 for a burette. Accurate delivery of intravenous fluids and drugs is available but is expensive and requires the operator to be specially trained. No simple, cheap, accurate device is yet available.
