Why is communication considered a patient safety issue?

Information lost or distorted during handoffs, orders, and team interactions is a recurrent contributor to adverse events, so structured communication and teamwork are treated as defences against harm.

Do surgical safety checklists actually improve outcomes?

An early multi-hospital study associated checklist use with lower complication and death rates, but later implementation studies found smaller or no effects, indicating that benefit depends strongly on genuine adoption rather than on the checklist alone.

Teamwork and Communication

Most modern healthcare is delivered by teams, and breakdowns in how those teams coordinate and exchange information are among the most common contributors to adverse events. Teamwork and communication describe the coordinated behaviours, shared mental models, and information exchange — including handoffs, briefings, and structured communication tools — through which clinicians work together safely.

Definition

Teamwork in healthcare is the coordinated, interdependent activity of clinicians pursuing shared patient-care goals through communication, mutual monitoring, and shared mental models; communication is the exchange of information through which that coordination is achieved.

Scope

This topic covers communication failures as a source of harm, structured communication and team-training interventions adapted from aviation crew resource management, and tools such as surgical safety checklists and briefings. It is a reference treatment of why teamwork matters for safety and how it is studied, not a how-to guide or clinical advice.

Core questions

How often do communication failures contribute to adverse events?
What behaviours distinguish effective from ineffective clinical teams?
Do team-training programmes and structured tools improve teamwork and outcomes?
How do checklists and briefings change communication in high-risk settings?

Key concepts

Communication failure as a root cause
Handoffs and transitions of care
Structured communication tools (e.g., briefings, read-back)
Surgical safety checklist
Shared mental models and mutual monitoring
Speaking up and authority gradient
Team training

Key theories

Crew resource management transfer: Insights from aviation — that error is reduced by flattening hierarchy, encouraging speaking up, and using structured communication — have been adapted into healthcare team training, on the premise that teamwork skills are learnable and transferable across high-risk domains.
Systems approach to error: Reason's model treats communication and coordination failures as latent and active conditions within a wider system; improving teamwork strengthens the defences that prevent latent weaknesses from causing harm.

Mechanisms

Effective teams maintain shared mental models, monitor each other's performance, and communicate explicitly at transition points, so that information is not lost during handoffs and concerns are voiced before they become harm. Structured tools formalise these behaviours: a surgical safety checklist prompts a team to confirm identity, procedure, and anticipated risks aloud before incision, while briefings and read-back reduce ambiguity. Team-training programmes draw on aviation crew resource management to teach these skills, aiming to flatten steep authority gradients that discourage juniors from raising safety concerns. Within Reason's systems framework, these interventions reinforce the human defences against error.

Clinical relevance

Teamwork and communication shape safety across every clinical setting where care is delivered by more than one person, and structured tools such as checklists and standardised handoffs are part of how organisations describe safe coordination. This entry explains the construct and the evidence around it; it does not prescribe how an individual team should be run or how a specific patient should be managed.

Epidemiology

Communication breakdowns are repeatedly identified among the leading contributing factors in analyses of adverse events, a concern highlighted by the 2000 To Err Is Human report. A large multi-hospital study across eight sites found that introducing a surgical safety checklist was associated with reductions in measured rates of complications and death, though the observational, before-after design limits causal interpretation. Cross-sectional surveys have documented differences between professional groups in attitudes toward hierarchy and speaking up.

History

Healthcare borrowed teamwork and communication models from aviation after the 2000 To Err Is Human report drew attention to system failures. Sexton and colleagues' 2000 survey compared attitudes in medicine and aviation, crew-resource-management ideas were translated into team-training curricula, and the World Health Organization's surgical safety checklist, evaluated by Haynes and colleagues in 2009, became an emblematic structured-communication intervention.

Debates

How large and durable are the effects of checklists and team training?: Initial multi-site results for surgical checklists were striking, but later implementation studies showed smaller or absent effects, suggesting outcomes depend heavily on how, and how genuinely, the tools are adopted rather than on the tool alone.
