The Near Miss Nobody Reported: Safety Culture, a Tubing Misconnection, and a Lewin-Based Plan for Change
A culture of patient safety is one in which staff share a commitment to safety, report errors and near misses without fear, and learn from them as a system. Its absence is often invisible until something goes wrong. This paper analyzes a composite scenario at a community hospital, used here in place of the scenario provided in the classroom, identifies the safety culture problems it reveals, selects Lewin's change theory as a framework for practice change, and applies that framework to a plan for the unit.
The Scenario
On a step-down unit at a composite community hospital, a nurse starting a night shift found that her patient's enteral feeding set had been connected to the patient's peripherally inserted central catheter rather than to his feeding tube. The pump had been started only minutes earlier, and she stopped it before any formula reached the patient. She reconnected the feeding correctly, checked the patient, and told the evening nurse privately, who was distraught. Neither filed an event report. The night nurse later explained that a nurse on the unit had been disciplined the previous year after reporting her own medication error, and that everyone had learned the lesson: report only what cannot be hidden.
The unit uses tubing sets whose connectors allow feeding tubes, intravenous lines, and other devices to be joined to one another. Handoffs are done at the nurses' station rather than at the bedside, and lines are not traced from the patient to the source during handoff.
Analyzing the Safety Culture
The most serious problem is not the misconnection but the silence that followed. A near miss is free information about a hazard; when it goes unreported, the hazard remains for the next patient. The staff's reluctance traces directly to a punitive response to a previous self-reported error, which taught the unit that reporting is dangerous. That is the opposite of a just culture, in which honest mistakes made within a flawed system are met with support and system repair, at-risk behaviors with coaching, and only reckless behavior with discipline.
The technical hazard is well documented. Tubing misconnections, in which a device is connected to the wrong type of line, have caused deaths when enteral feedings or other substances were delivered intravenously, and a consortium of professional organizations called for connectors that make such errors physically impossible, along with practices such as tracing lines to their origin (Guenter et al., 2008). Here the system made the error easy to make and the culture made it easy to hide.
Evidence on changing safety culture is encouraging but limited. A systematic review of interventions in acute care, including executive walk rounds, unit-based multicomponent programs, and team training, found that most studies reported some improvement in safety culture or patient outcomes, although the strength of evidence was low and most studies used before-and-after designs (Weaver et al., 2013). Culture can change, but it changes through sustained, visible leadership rather than a single policy.
Selecting a Framework: Lewin's Change Theory
Lasting change, in the account Lewin (1947) gave, passes through three stages that later writers labeled unfreezing, moving, and refreezing. Unfreezing creates readiness by making the need for change clear and reducing the forces that resist it. Moving introduces the new practices. Refreezing stabilizes them so the unit does not drift back. Lewin's model suits this situation because the obstacle is not a lack of knowledge but a set of learned behaviors and fears that must be loosened before any new practice can take hold. A technical fix introduced without unfreezing the fear of reporting would leave the silence intact.
Applying the Framework
Unfreezing. The nurse manager, with the support of the director, acknowledges to staff in a unit meeting that the previous disciplinary response was a mistake and that the hospital is adopting a just culture approach. The manager shares, with permission and without names, the story of the near miss as an example of why reporting matters, and thanks the nurses who later chose to report it. Staff complete a safety culture survey to establish a baseline.
Moving. The unit replaces enteral feeding sets with connectors designed so they cannot join intravenous devices, and adopts bedside handoff that includes tracing every line from the patient to its source and labeling lines at the connection points. Event reporting is simplified to a short form, and the manager responds to each report within a week with a thank-you and a note of what will change. A monthly safety huddle reviews recent near misses as learning opportunities.
Resistance should be expected and planned for. Some nurses will doubt that the new approach is sincere until they see how the first report after the meeting is handled, so the manager's response to that report matters more than the meeting itself. Others will object that bedside line tracing lengthens handoff; timing a sample of handoffs before and after the change, and sharing the result, answers that concern with data rather than argument. The evening nurse from the near miss may be willing, with support, to describe what the experience was like, which can move colleagues more than any policy. In Lewin's terms, each of these steps weakens a restraining force rather than simply pushing harder with a driving one.
Refreezing. Line tracing becomes part of the handoff checklist and annual competencies, the connector change is made hospital-wide, and the safety culture survey is repeated after one year. Near-miss reports are tracked monthly. An increase in reports during the first months should be read as success, not failure, because it shows staff now believe reporting is safe.
Conclusion
The composite scenario shows how a hazardous system and a fearful culture reinforce each other: compatible connectors made a misconnection possible, and a punitive history ensured that it would not be reported. Lewin's model provides a structure for change that begins by unfreezing the fear, moves the unit to safer equipment, bedside line tracing, and supportive responses to reporting, and refreezes those practices through policy, competencies, and measurement. A culture of safety is built one report, and one response, at a time.

How this N 496 Module 7 example is structured
N496 Module 7 typically asks you to analyze a patient safety scenario provided in the classroom and select a framework for practice change, in about 1,000 to 1,250 words. That scenario is not reproduced here; this example uses its own composite hospital so the method can be shown. It separates the cultural problem from the technical one, supports each with a source, justifies the framework by the nature of the problem and applies each stage of the framework with specific actions and measures.
N496 Module 7 questions, answered
What does N496 Module 7 usually ask for?
Commonly a paper of 1,000 to 1,250 words analyzing a patient safety scenario provided in the course and selecting a framework to guide a practice change. The module's discussion often addresses workplace conflict, bullying and stress management.
Which change framework should I choose?
Choose the one that fits the nature of the problem and explain why. Lewin's model suits problems rooted in behavior and fear because it begins with unfreezing; Kotter's eight steps suit larger organizational change; the Model for Improvement with PDSA cycles suits testing specific process changes.
What is a just culture?
An approach to safety that distinguishes honest human error, which is met with support and system repair, from at-risk behavior, which is met with coaching, and reckless behavior, which may warrant discipline. It encourages reporting because staff are not punished for honest mistakes.
