This is in stark contrast to the fact that these sophisticated devices are frequently implicated in the harm done to patients. The FDA discovered that the complexity of the pumps was responsible for 56,000 adverse drug events, some of which were harmful or fatal, over the course of that time period. In addition to device malfunctions, ambiguous user interfaces and poorly designed products, among other things, are to blame for these incidents, which occur frequently.
In April 2011, the Agency for Healthcare Research and Quality awarded funding to a multidisciplinary team from Johns Hopkins University, led by researchers from the Armstrong Institute and the Applied Physics Laboratory (APL), with the goal of developing and evaluating a prototype for an Infusion Pumpb with the goal of reducing these risks. All of the people who worked on the project were able to finish it by the end of 2014. The team included systems engineers, human factors engineers, clinicians, software developers, and project analysts.
Users' expectations of infusion pumps are determined in the first phase, and then those expectations are put into action.
The investigators took a systems engineering approach to their work, starting with an attempt to understand the needs of Infusion Pumpb users and other stakeholders before moving on to other tasks. At a summit hosted by APL in January 2012, participants identified five categories of needsSyringe Pump needed to be addressed by the organization as a result of the summit. Nurses, physicians, engineers, manufacturers, and regulators were among those who took part in the conference.
It is beneficial to have a better understanding of the patient's condition and medical treatment, such as being awareInjection Pump other pumps are also delivering the same medication to the patient.
In interfaces, information is presented and prioritized more effectively, and the information is more visible from a variety of perspectives, including from a distance and in different lighting conditions.
In order to achieve pump control standardization, it is necessary to use more consistent terminology and place functions in the same locations across different pump designs. This is especially true when it comes to critical commands such as Run and Stop.
In the second phase, the design and construction of a prototype for an Integrated Syringe Pump will take place.
It is also possible to continue infusion after a bolus has been administered, which is another feature of the prototype that improves patient safety and usability.
After administering a medication bolus, the pump continues the medication's infusion for an additional period of time using the same medication. A number of users expressed concern about forgetting to reset their pumps, which was echoed by others.
Clinical assistants provide assistance to clinicians in the course of their daily activities. With the assistance of subject matter experts, an interfaceSyringe Pump is consistent with the user workflow was developed.
Parts that are easy to locateAll of the most important commands, as well as their locations within the pump, were straightforward to locate.
Prototyping, testing, and evaluation are all terms used to describe the third phase.
A total of twenty-one clinicians were trained on the new pump user interface design before being asked to complete a series of tasks in an artificially created hospital environment, using both the auto-programming and manual programming modes, on the day of the test. Participants agreedInjection Pump auto-programming could help to prevent misinterpretation of doctor's orders and programming errors, while also reducing the mental load placed on users themselves. Another advantage of using automatic programming over manual programming was there were fewer high-risk errors committed in the former than in the latter, which was another advantage of using automatic programming over manual programming.
