Every time care passes from one person to another, information can be lost. Shift changes, transfers, and discharges are among the most common points where a plan, a pending test, or a warning quietly disappears, and where a diagnosis can be delayed.
This guide covers structured handoff formats such as SBAR and I-PASS, why several layers of defense beat a single one, how to close the loop on pending results, and how to audit handoffs with a simple measure. The worked example shows what a realistic before-and-after audit looks like.
Before You Start
Why Handoffs and Follow-Up Matter
Information Is Lost at Every Transfer
Shift changes, transfers between units, and discharge all move a patient's story from one person to another, and details drop out.
Handoff Failures Are a Recognized Safety Issue
The Joint Commission's Sentinel Event Alert 58 addressed inadequate hand-off communication as a contributor to patient harm.
Delays Hide in Pending Results
A test that is ordered but never followed up, or a result that reaches nobody, is one of the main routes to a missed or late diagnosis.
Structure Works
Standard formats and closed-loop communication turn a personal habit into a reliable process.
Why One Safeguard Is Never Enough
James Reason's Swiss cheese model describes how harm usually happens: a hazard passes through a series of defenses, each with holes, and only reaches the patient when holes in every layer line up. The model is useful here because a handoff has several layers, and improving any one of them shrinks the chance that the holes align.
Common Handoff Formats
| Format | What it stands for | Best used for |
|---|---|---|
| SBAR | Situation, Background, Assessment, Recommendation | Urgent communication and escalation between clinicians, such as calling about a change in condition. |
| I-PASS | Illness severity, Patient summary, Action list, Situation awareness and contingency planning, Synthesis by receiver | Shift-to-shift and unit-to-unit handoffs of care, especially where the receiver must act on a to-do list. |
| Read-back | Receiver repeats the key information back to the sender | Verbal orders, critical results, and high-risk instructions. |
In a multicenter study in pediatric residency programs, Starmer and colleagues reported in the New England Journal of Medicine (2014) that implementing the I-PASS handoff bundle with training was associated with a 23% reduction in medical errors and a 30% reduction in preventable adverse events. Results depend heavily on training and reinforcement, and you should check the current evidence for your setting.
Closing the Loop on Test Results
Diagnostic delay often comes from an open loop: a test is ordered, and nobody is sure who owns the result. Three habits close it:
- Name an owner. Every pending test has one person accountable for reviewing the result and telling the patient.
- Track pending items. A list of tests ordered but not resulted, and results not yet acknowledged, reviewed at every handoff.
- Escalate critical values. Critical results follow a defined path with read-back and a time limit, not a message left in an inbox.
Worked Example: A Shift-Change Audit
A unit audits 50 shift-change handoffs and checks whether pending tests were mentioned, since these are a known weak spot. The numbers are illustrative.
| Measure | Before | After a standard tool and training |
|---|---|---|
| Handoffs audited | 50 | 50 |
| Handoffs missing the pending-test item | 18 (36%) | 5 (10%) |
| Handoffs with a receiver read-back | 11 (22%) | 39 (78%) |
The missing-item rate fell by 26 percentage points, a relative reduction of 72%. The team had three levers: a one-page template with a mandatory "pending results" line, a standing agreement that the receiver repeats back the top two actions, and weekly spot audits with feedback to the team. They also tracked a balancing measure, minutes spent per handoff, which rose by about two minutes. Whether that trade is acceptable is a judgment for clinical leaders; the data at least make the trade visible.
Record audits in the Clinical Handoff and SBAR Checklist Template, which calculates completion by element.
Designing a Handoff That Works
A good handoff is a short, structured exchange that gives the receiver what they need to act, with a chance to ask questions. It is not a recital of the chart. Designing it means deciding what must be said, in what order, and how the receiver confirms understanding.
Use one format and keep it short. Formats such as SBAR (situation, background, assessment, recommendation) and I-PASS (illness severity, patient summary, action list, situation awareness and contingency planning, synthesis by the receiver) exist because they have been tested. The best format is the one your staff will use consistently, adapted for your setting.
Give the most important thing first. Who is unstable? What must happen in the next few hours? What could go wrong, and what should the receiver do if it does? Routine details can be in the record.
Make it two-way. The receiver should summarize what they heard. Sender and receiver should be free from interruption for the duration. Where practical, handoff at the bedside lets the patient and family hear and correct the information.
Support it with the environment. A quiet space, a printed or electronic template that prompts the key items, and protected time are not luxuries; they are what makes a format usable.
Auditing and Sustaining Good Handoffs
A format introduced by memo fades within weeks. To keep a handoff practice alive, observe it, measure it, and give feedback.
| Measure | How to collect it | What it tells you |
|---|---|---|
| Share of handoffs using the format | Direct observation of a sample each week | Adoption |
| Critical items missing | Observer checklist against the record | Quality of the content |
| Interruptions during handoff | Observation | Environment and protected time |
| Questions asked by the receiver | Observation or short survey | Whether it is truly two-way |
| Events or near-misses linked to a handoff | Event reports, reviewed monthly | Outcome and whether the format is working |
Observe, then coach. Observers should be colleagues, not inspectors, and should share what they saw while it is fresh. Positive feedback on what went well builds the habit as much as correction does.
Keep the loop on test results and follow-up. A result that returns after the patient leaves needs a named person who will act on it. Audit a sample of pending results regularly, and track the time from result to action. Assign ownership explicitly when the ordering clinician changes shift or unit.
Common pitfalls. A template that becomes a box-ticking exercise; a format so long that no one finishes it; a handoff done while staff are also answering alarms; and blaming individuals when a handoff fails rather than asking what made the failure likely. See the Patient Safety and HFMEA Guide for anticipating failure points. The figures in the examples are illustrative and do not replace your own measurements. This guide is not clinical advice.
Self-Assessment Questions
- Do we use one agreed handoff format, or does each person do it their own way?
- Does every handoff include pending tests and an action list?
- Does the receiver confirm understanding, not just listen?
- Is there a named owner for every pending result?
- Do we audit real handoffs and share the results with the people doing them?
Common Mistakes
Training Once and Moving On
Handoff habits fade without reinforcement. Build audits and coaching into the routine.
Using a Format Without Buy-In
A form imposed without explanation gets pencil-whipped. Involve the people who hand off in designing it.
Interrupted Handoffs
Handoffs in a noisy, interrupted setting lose information. Protect the time and place where practical.
Measuring Only Whether the Form Was Filled In
Completion of a form is not communication. Audit whether the receiver understood the key points.
Reducing Handoff Errors and Diagnostic Delay: Frequently Asked Questions
What is the difference between SBAR and I-PASS?
SBAR (Situation, Background, Assessment, Recommendation) is a short structure for urgent communication, such as escalating a change in a patient's condition. I-PASS is a longer handoff bundle used at shift change or transfer that adds illness severity, an action list, contingency planning, and a synthesis in which the receiver repeats back the plan.
Why do handoffs fail?
Common reasons are no standard format, interruptions and noise, information that lives only in someone's memory, unclear ownership of pending results, and no confirmation that the receiver understood. Improving any one of these reduces the chance that gaps line up and harm reaches the patient.
How can we measure handoff quality?
Audit a sample of real handoffs against the elements you require, such as pending tests, action list, and read-back, and track the percentage complete over time. Pair it with a balancing measure such as time per handoff, so the team can see the trade-offs.
