Beyond the Swiss Cheese Model: How message accountability closes critical communication gaps

uring a busy shift change, a nurse giving a handoff report to an oncoming colleague entered a patient’s room to verify IV pump settings and attachments to chest tubes, drains, and PIVs. The patient and his wife said they had been waiting, as the patient had moved from the bed to the chair and accidentally disconnected his chest tube.

The care team immediately began the necessary interventions and followed the chest tube management protocol.

The patient’s wife had used the nurse call system to reach a nurse, but whoever answered the call never relayed that message. In fact, that person may not have understood the critical nature of the situation. Luckily, the patient was fine—but the situation highlighted something important.

A breakdown in communication nearly led to a serious patient safety event. Clearly, the unit’s communication practices had some major holes that needed to be addressed.

What is the Swiss Cheese Model in healthcare?

In healthcare, adverse events rarely happen because of a single mistake. More often, they occur when multiple small breakdowns align: missed messages, unclear urgency, or lack of follow-through. The Swiss Cheese Model in healthcare describes exactly this phenomenon and how these gaps can stack up and lead to harm.

Rather than focusing on the Swiss Cheese Model itself, it’s more useful to focus on what it represents: communication failures that go unnoticed until they matter most.

Despite advances in communication technology, the problem persists. According to a recent analysis, communication failures between providers and patients or families now appear in over 60% of communication-related cases, and remains one of healthcare’s most persistent and growing challenges. The goal of any modern communication strategy is to reduce these gaps and ensure critical information reaches the right person, at the right time, with the right level of urgency.

Not all messages are equally important

One of the biggest challenges in healthcare communication is that not all messages carry the same weight. For example, telling a physician “The family is in the room and would like to talk to you,” is different than “The CT scan shows a new, acute subdural hematoma with midline shift.” Both messages matter, but only one requires immediate clinical intervention.

Without clear prioritization and accountability, critical messages can be delayed, overlooked, or misunderstood—leading to poor patient outcomes.

Message accountability: A strategy to close gaps in patient safety systems

When it comes to closing the gaps identified by the Swiss Cheese Model, message accountability offers a practical, systems-level approach to reducing communication failures and improving patient safety. Unlike simply sending information, it ensures responsibility is clearly transferred and acted upon.

A strong secure communication process includes:

• Actionable content: Messages include clear context and urgency, so the recipient understands what needs to happen.
• Explicit acknowledgment: The recipient confirms receipt and takes ownership of the message.
• Delivery and acceptance: The sender knows when the message has been received and accepted.
• Automated escalation: If a message is not acknowledged within a defined timeframe—or sent to the wrong person—it is automatically escalated to the appropriate individual.

Where message accountability matters most

The following scenarios illustrate how communication gaps create risk and how message accountability helps close them:

1. Code situations

When a patient arrives in the ED with an acute ST-elevation myocardial infarction (Code STEMI), the cardiac catheterization team must be activated immediately. The care team needs confirmation that the interventional cardiologist received the message and is on their way—otherwise treatment is delayed. Having the right on-call scheduling and communication processes in place is critical.

2. Critical test results

When a CT scan reveals an acute subdural hematoma, it’s a medical emergency that demands the care team mobilize without hesitation. The radiologist identifies the issue, but responsibility must quickly transfer to the treating provider and often to a specialist such as a neurosurgeon.

A Clinical Test Result Notifications solution ensures that:

• Critical results are delivered immediately
• The appropriate provider acknowledges the result
• Escalation occurs automatically if there is no response

This accountable communication process helps ensure that life-threatening findings are acted on without delay.

3. Patient care alarms

When a patient presses the nurse call button, the request may range from routine to urgent. Without clear ownership, these messages can fall through the cracks. Accountability ensures that a responsible caregiver receives and responds appropriately.

How to improve communication to prevent clinical errors

Clinicians across healthcare have experienced near misses or adverse events tied to communication breakdowns. The Swiss Cheese Model reminds us that no single safeguard is perfect and while we can’t eliminate every risk, we can significantly reduce them by improving how information flows across care teams.

Modern solutions, like a Clinical Test Result Notifications system, help ensure that critical information doesn’t just get sent, but is received, acknowledged, and addressed without delay.

By focusing on accountability and closing communication gaps, healthcare organizations can strengthen patient safety and reduce the risk of errors — patching the holes the Swiss Cheese Model warns us about, one message at a time.
