From Two Nurses to Forty: Using Diffusion of Innovations Theory to Spread Ultrasound-Guided IV Placement in a Composite Emergency Department
Many useful innovations in health care fail not because they do not work but because they do not spread. Planned change models help leaders move from a good idea to a new routine. This paper applies Rogers' diffusion of innovations theory, extended by a systematic review of diffusion in service organizations, to one problem in a composite emergency department: patients with difficult intravenous access who wait too long and endure too many needle sticks. It proposes a plan to spread nurse-performed ultrasound-guided peripheral IV placement from two trained nurses to the whole nursing staff.
The Problem
Mercy East Emergency Department is a composite 42-bed department with roughly 70,000 patient encounters annually. A two-week audit found that 14 percent of patients who needed IV access had difficult access, defined as two failed attempts, and that these patients averaged 3.4 attempts, waited a median of 58 minutes for access, and often received central lines or were referred to physicians with ultrasound training. Two nurses learned ultrasound-guided placement at a conference and use it successfully, but the rest of the 40-member nursing staff has not adopted it, even though two portable ultrasound machines are available.
The Evidence for the Innovation
The case for change rests on evidence. A meta-analysis of eight studies with 1,660 adult patients found that ultrasound guidance increased the success rate of peripheral IV cannulation, 81 percent compared with 70 percent for conventional techniques, and reduced the number of punctures and the time needed to achieve access while improving patient satisfaction, although it did not reduce complications (van Loon et al., 2018). For patients with difficult access, fewer attempts and faster access mean less pain, earlier treatment, and fewer central lines, which carry their own risks.
Diffusion of Innovations Theory
Rogers (2003) defines diffusion as the process by which an innovation is communicated through certain channels over time among the members of a social system. Five attributes of an innovation shape how quickly it is adopted: relative advantage, whether it is seen as better than current practice; compatibility, whether it fits existing values and routines; complexity, how difficult it is to learn; trialability, whether it can be tried on a limited basis; and observability, whether its results are visible to others. People take up an innovation at different speeds, and Rogers sorted them into five groups: innovators, early adopters, an early majority, a late majority, and laggards, and change agents are most effective when they work through respected early adopters, often called opinion leaders.
Greenhalgh et al. (2004) extended the theory to health services after reviewing hundreds of studies. They found that adoption depends not only on the innovation and individual adopters but also on the organization's readiness, the resources committed, the linkage between those who develop and those who use an innovation, and the degree to which the innovation can be adapted to local circumstances.
Applying the Theory to Mercy East
Relative advantage is high but not yet visible to most staff, so the plan makes it visible: the two nurses' success rates and time-to-access figures will be shared at staff meetings, and patient comments will be posted. Compatibility is good because nurses already value first-attempt success and patient comfort, and IV placement is already a nursing task. Complexity is the main barrier, since ultrasound requires new hand-eye coordination; the plan reduces it with a four-hour simulation workshop using vascular access models, followed by supervised insertions on real patients. Trialability is built in, since nurses can try the technique first on patients who have already had failed attempts, where the benefit is clearest. Observability will come from a unit board tracking the number of ultrasound-guided placements and first-attempt success.
The two current users are the innovators. The plan will identify six early adopters, respected nurses from each shift, as champions, train them first, and ask them to supervise colleagues. Nurses are more likely to adopt a technique they watch a trusted colleague use at 3 a.m. than one they hear about in a mandatory in-service. The late majority will be reached by making ultrasound the expected next step after two failed attempts, written into the department's IV access protocol.
Organizational Readiness and Resources
Because organizational readiness and committed resources shape adoption as much as individual attitudes (Greenhalgh et al., 2004), the plan secures organizational support before training begins. The department's medical director has agreed that nurses may perform ultrasound-guided placement under a written protocol, the education budget covers the workshop and paid supervision time, and a third ultrasound machine will be purchased if use exceeds capacity. The protocol will address competency requirements, documentation, catheter length for deeper veins, and infection prevention for the probe.
Resistance should be expected and understood rather than overridden. Some experienced nurses take pride in finding veins by touch and may see ultrasound as a threat to a hard-won skill; others worry about the extra time on a busy shift. The champions will acknowledge both concerns, emphasize that ultrasound is for patients who have already had failed attempts rather than a replacement for traditional skill, and show that a successful first ultrasound attempt usually takes less total time than a third or fourth blind stick.
Measuring the Change
Success will be measured against the baseline audit six and twelve months after launch: the number of nurses competent in the technique, the median time to access for patients with difficult access, the average number of attempts, the proportion of these patients receiving central lines, and patient satisfaction with IV placement. Complication rates, including infiltration and early catheter failure, will also be tracked, since the meta-analysis did not show a reduction and deeper veins may carry a higher risk of failure.
Conclusion
Ultrasound-guided IV placement works, but at Mercy East it has spread to only two nurses. Diffusion of innovations theory explains why and shows how to change that: make the advantage visible, reduce complexity through training, let nurses try the technique where it helps most, work through respected early adopters, and secure organizational support. With these steps, the department can move from two nurses to forty and give patients with difficult veins faster, less painful care.

How this N 522 Module 6 example is structured
N522 Module 6 typically applies a planned change model to one real problem. Aspen does not publish module deliverables, so check your classroom for the exact prompt. This example quantifies the problem, presents the evidence honestly, explains the change model with its sources, maps each element of the model to a plan step and closes with measures tied to the baseline.
N522 Module 6 questions, answered
What does N522 Module 6 usually ask for?
The module typically asks you to apply a planned change model, such as Lewin, Kotter or diffusion of innovations, to one real problem in an organization you know. Aspen does not publish module deliverables, so your classroom's instructions govern.
What are the five attributes in diffusion of innovations theory?
Relative advantage, compatibility, complexity, trialability and observability. Innovations that are clearly better, fit existing values, are easy to learn, can be tried on a small scale and produce visible results spread faster.
Why work through early adopters?
Early adopters are often respected opinion leaders. When colleagues see them use an innovation successfully, the early and late majority are more likely to follow than they would be from formal training alone.
