In this review of tenders of public procurement in Spain for supplying 12.224 volumetric and syringe infusion pumps and consumables for a budget of 30.4M€, we identified the main requirements and criteria for the selection in 63 different batches and specifically analyzed patient safety and human factors related elements. Our data indicate that requirements related to patient safety, such as dose error-reduction systems, alarms, or pump blocking systems are frequently considered as requirements or criteria, independently of the type of infusion pump. In this sense, references to the usability-related terms of the equipment as “ease”, “intuitive” or “usable” were identified in both selection requirements and criteria of the tender documentation in more than half of the cases.
Although concepts related to physical and cognitive ergonomics were present in many of the procurements, no experts in patient safety or human factors were included in the assessment teams of the tenders. With respect to the evaluation of pump usability, no specific methods such as heuristic evaluation or usability testing were identified for any of the procurements.
Since infusion pumps are involved in adverse events, the FDA and other international agencies and associations have launched several initiatives focused on these devices, to improve patient safety, including purchasing procurement strategies. The FDA, in their Infusion Pump Initiative, defines several strategies for risk reductions that include formulating and implementing a plan to evaluate infusion pumps prior to purchasing or renting17. In England, the Medicines and Healthcare Products Regulatory Agency24 emphasized that procurement decision-making should be informed by safety performance and reliability assessments. In Canada, the Western Canada Human Factors Collaborative25 demonstrates that when human factors evaluations are incorporated into procurement activities, procurement committees are better informed, so that chosen devices, equipment, and technologies are more usable, effective, and safer for patients and end-users. This guidance provides comprehensive recommendations on how one may integrate human factors evaluations into procurement processes.
Despite the mentioned recommendations, some data suggest that patient safety is not usually considered as one relevant driver of healthcare technology procurement30. One investigation of the Healthcare Safety Investigation Branch31 found that the procurement of smart pump technology is not primarily driven by the need for smart functionality and was not subjected to a risk assessment or requirements analysis. This agency reinforces that when selecting smart pump devices, it is important to consider how this is likely to impact practice, however, this rarely drives the procurement process.
Currently, public procurement in Europe is an essential vehicle for implementing government policies and meeting national strategic objectives, as well-functioning public procurement markets contribute to improving the competitiveness of quality service strategies32. In addition, new strategies are needed to ensure that public procurement addresses the social existing challenges such as environmental protection and sustainable consumption and production33 in addition to patient safety35. Recent recommendations to improve the safety of infusion pumps reinforce the need to involve large organizational purchasers of these technologies as they can influence infusion device and management system design with manufacturers9.
Several reports have been published in relation to human factors evaluation, specifically of infusion pumps, related to the comparison of different equipment34, for improving existing designs11 or for supporting new design35,36. However, human factors evaluation is not a usual practice as a supporting decision tool in medical technology in general30. In fact, most medical technology procurement is driven by engineering standards, and the emphasis is on functional requirements rather than those relating to social or organizational needs37. Few experiences have been reported in the procurement of volumetric and syringe infusion pumps that incorporate human factors in the decision-making process, pointing out that it adds great value38–43 and demonstrate that HFE evaluation methods, as heuristics or usability evaluation, are affordable as part of the public procurement pathway of infusion pumps with adequate timing, planning, and multidisciplinary teams.
Implementation is a relevant issue of healthcare technology, specifically for improving infusion pump safety. Procurement processes should consider the implementation resources needed, potential barriers and risks to implementation, and the global impact on the organizations during implementation44. Our data support previous reports that indicate that the potential of the pumps related to their interoperability and dose error-reduction systems is not widely exploited45,46.
This study has some limitations. The database used to retrieve procurement documents may not be comprehensive. Our analysis is focused on data from one country and does not represent all of Europe. Future studies should consider other countries or even other public organizations for greater generalizability.
