SBAR nursing communication is a four-part structured handoff and escalation tool used across hospital and community nursing practice. The acronym stands for Situation, Background, Assessment, and Recommendation, and the tool exists to compress clinical information into a predictable, time-efficient form for shift handoffs, transfers between units, escalation calls to providers, and rapid-response activations. SBAR originated in the United States Navy nuclear submarine fleet, was adapted for healthcare by Kaiser Permanente in 2002, and was endorsed by the Joint Commission as a recommended handoff format following the 2006 National Patient Safety Goal on communication. EssayFount writing experts use this guide with pre-licensure students writing first SBAR transcripts, RN-to-BSN students writing communication-improvement papers, MSN students writing quality-improvement project reports, and DNP students framing communication-failure capstones.
Where SBAR came from: the submarine fleet, Kaiser Permanente, and the Joint Commission
The Situation-Background-Assessment-Recommendation structure was developed in the United States Navy by the nuclear submarine fleet, where short, structured radio communication between submarines and surface command was needed to compress complex tactical information into a predictable format under time pressure. The format moved into healthcare in 2002 when Doctor Michael Leonard, then physician leader for Patient Safety at Kaiser Permanente of Colorado, adapted the structure for clinical handoffs and escalation calls. The internal Kaiser project documented improvements in the predictability of resident-to-attending communication and was published in the patient-safety literature in the early 2000s.
The Joint Commission's 2006 National Patient Safety Goal on improving the effectiveness of communication among caregivers required hospitals to implement a standardised approach to handoff communications, and SBAR became the most widely adopted format in US hospitals by the late 2000s. The Institute for Healthcare Improvement included SBAR in its 100,000 Lives Campaign and subsequent communication-improvement work, and the format is now embedded in pre-licensure nursing curricula across the United States, the United Kingdom, Australia, and Canada. The World Health Organization's Communication During Patient Hand-Overs patient-safety solution (2007) cites SBAR as a leading example of structured communication.
The empirical literature on SBAR is mixed but generally positive. Systematic reviews published in BMJ Quality and Safety and the Journal of Nursing Care Quality through the 2010s and early 2020s find consistent improvements in the structure and completeness of handoff communications, with weaker but still positive evidence for downstream effects on adverse events. The strongest empirical results appear in studies of escalation calls (where SBAR replaces an unstructured call to a provider) and in studies of nurse-to-physician communication in deteriorating-patient scenarios.
S, Situation: the one or two sentences that name the problem
The Situation portion of an SBAR opens the communication and names what is happening right now. Standard wording covers the speaker's name and unit, the patient's name and room number, and the reason the speaker is calling or handing off. Length should be one to two sentences. The discipline of the Situation portion is restraint: it states the problem without launching into the history that belongs in Background or the data that belongs in Assessment.
A Situation reads, for example: "This is Maria Reyes from the cardiac step-down unit. I am calling about Mr Henry Fitzgerald in room 312 because his blood pressure has dropped to 82 over 50 over the last hour and he is now reporting lightheadedness." Twenty-six words, two sentences, and the listener already knows who is speaking, who the patient is, and what the issue is. The escalation that follows builds on that base.
B, Background: the history that the listener needs to interpret the Situation
The Background portion supplies the clinical context that the listener needs to make sense of the Situation. It typically covers the admission diagnosis, the relevant medical history, the current treatment plan, the medications related to the issue, allergies if relevant, and any recent procedures or events that bear on the current presentation. Background is not the patient's full chart; it is the slice of the chart that explains the Situation.
For the cardiac step-down case, Background reads: "Mr Fitzgerald is a 71-year-old man admitted three days ago after a non-ST-elevation myocardial infarction. He had a successful percutaneous coronary intervention to the left anterior descending artery on day one. His current medications include metoprolol 25 milligrams twice daily, lisinopril 10 milligrams daily, atorvastatin 80 milligrams nightly, and aspirin 81 milligrams daily. He has been clinically stable since transfer from the cardiac intensive care unit yesterday morning, with blood pressures running 110 to 130 systolic until this episode."
The discipline of the Background portion is filtering. The patient's history of a remote cholecystectomy and his preference for decaffeinated coffee are not relevant to a hypotensive episode; the metoprolol dose, the recent percutaneous coronary intervention, and the trend in vital signs are. Strong SBARs include only the background that explains the Situation, and graders read for that filtering.
A, Assessment: the speaker's clinical judgement, not the assessment data
The Assessment portion gives the speaker's clinical judgement about what is going on. The portion is sometimes misunderstood as a data dump (every vital sign, every recent value), but the structured-communication literature is clear that Assessment is the speaker's interpretation of those data. Specific data points belong here only when they directly support the interpretation.
For the cardiac case, Assessment reads: "I think Mr Fitzgerald is becoming hypotensive secondary to his beta-blocker dose, possibly compounded by mild dehydration: he has not been drinking well today, his urine output has dropped to 25 millilitres per hour over the last two hours, and his heart rate is 56 (which is on the low side of his usual range). He is alert and oriented but reports the new lightheadedness on standing. I am concerned about cardiogenic versus hypovolaemic causes." The listener now has the speaker's working hypothesis and the data points that support it.
The Assessment portion is what most distinguishes a strong nurse-to-provider call from a weak one. A nurse who calls a provider with Situation and Background but no Assessment leaves the provider to do the diagnostic reasoning from scratch; a nurse who calls with an Assessment opens the conversation at a higher level and shortens the path to a clinical decision.
R, Recommendation: what the speaker is asking the listener to do
The Recommendation portion closes the communication with the speaker's request. The request can be specific (please order a fluid bolus, please come to the bedside to evaluate, please hold the next dose of metoprolol) or open-ended (what would you like me to do?), and the literature supports a specific request when the speaker has the clinical knowledge to make one.
For the cardiac case, Recommendation reads: "I would like to hold the next scheduled dose of metoprolol, start a 250-millilitre normal saline bolus, recheck vital signs in fifteen minutes, and have you evaluate at the bedside. Is that acceptable, or would you like to do something different?" The provider can accept the plan, modify it, or supply an alternative; either way, the conversation has a closing point and the next action is named.
A worked shift-change handoff: nurse Maria to nurse David at 0700
The most-written SBAR nursing transcript in pre-licensure assignments is the shift-change handoff. The format here is brief because the receiving nurse will read the chart in detail; the SBAR carries the essential transfer of clinical attention. The transcript below is for the same Mr Fitzgerald case, on the morning after the hypotensive episode resolved.
Situation: "Mr Fitzgerald in room 312 is a 71-year-old man post-NSTEMI day four, post-PCI day three. He had a hypotensive episode yesterday evening that resolved with one fluid bolus and a held metoprolol dose. He is currently stable."
Background: "He was admitted Tuesday with chest pain, found to have a non-ST-elevation myocardial infarction, and had a percutaneous coronary intervention to the LAD on Tuesday afternoon. He was transferred from the cardiac intensive care unit Wednesday morning. His current medications are metoprolol 25 milligrams twice daily, lisinopril 10 milligrams daily, atorvastatin 80 milligrams nightly, and aspirin 81 milligrams daily. The provider held last night's metoprolol dose; the morning dose has been ordered to resume."
Assessment: "Overnight he has been stable: blood pressures 118 to 124 systolic, heart rate 64 to 70, oxygen saturation 96 percent on room air, and he slept four hours straight without complaint. His urine output has improved to 60 millilitres per hour over the last six hours. He is alert and oriented, no chest pain, no recurrence of lightheadedness."
Recommendation: "Please give the morning metoprolol when due, monitor blood pressures every two hours through the morning, encourage oral fluids, and call the cardiology team if his systolic blood pressure drops below 100 again. The patient is asking about discharge planning; the team has not committed to a discharge date yet."
A worked rapid-response activation: nurse Carol calling the rapid-response team
The escalation transcript is shorter and faster. The receiver of a rapid-response call is a critical-care or emergency clinician arriving at the bedside, and the SBAR has to compress quickly. The transcript below is for a different patient: a 56-year-old woman post-operative day three after an elective open cholecystectomy who is now showing signs of sepsis.
Situation: "This is Carol on 4 South. I am activating a rapid response on Mrs Janet Howard in room 425. She is hypotensive at 86 over 48, her heart rate has climbed to 124, and her oxygen saturation has dropped to 89 percent on room air."
Background: "She is a 56-year-old woman post-operative day three after an open cholecystectomy on Sunday. She has a history of type two diabetes and hypertension. She was stable through yesterday but has been febrile since this morning, with a maximum temperature of 38.9 degrees Celsius. Her surgical site is erythematous and warm with serous drainage."
Assessment: "I am concerned about sepsis, possibly from a surgical-site infection. She is meeting two of the four systemic inflammatory response criteria (heart rate over 90, temperature over 38), her urine output has dropped to 15 millilitres per hour, and she is mildly confused for the first time. She has been on no antibiotics since the prophylactic dose at surgery."
Recommendation: "Please come to the bedside now. I have placed her on a non-rebreather and I am drawing blood cultures and a lactate. I need provider orders for fluid resuscitation and broad-spectrum antibiotics."
A worked transfer SBAR: emergency department to medical-surgical floor
The transfer SBAR is the most detailed of the three because the receiving nurse is taking over from a clinician who has been with the patient for hours, not minutes, and the receiving unit needs the full clinical picture. The transcript below is for a patient transferring from the emergency department to a medical-surgical floor after admission for community-acquired pneumonia.
Situation: "I am bringing you Mr Robert Patterson from the emergency department. He is a 64-year-old man being admitted for community-acquired pneumonia. He is currently stable, on two litres of oxygen by nasal cannula, with a saturation of 94 percent."
Background: "He presented this afternoon with a four-day history of productive cough, fever to 39 degrees, and progressive shortness of breath. His chest X-ray shows a right lower lobe infiltrate. His white blood cell count is 18 thousand, his lactate was 2.1, and his blood cultures and sputum cultures are pending. His past medical history includes COPD on inhalers, type two diabetes, and a 40 pack-year smoking history. He has no known drug allergies. He has had two litres of intravenous normal saline, ceftriaxone one gram, azithromycin 500 milligrams, and acetaminophen 650 milligrams in the emergency department."
Assessment: "He is responding well to initial treatment. His temperature has come down from 39 to 37.8 since the antibiotics. His oxygen requirement has dropped from four litres to two over the last three hours. He is alert, conversant, and complaining mostly of fatigue and a productive cough. His blood pressure has remained stable in the 130s over 80s. He is not currently meeting sepsis criteria but is at risk of decompensation if antibiotics are delayed."
Recommendation: "Please continue ceftriaxone every twenty-four hours and azithromycin every twenty-four hours per orders. The provider has ordered incentive spirometry every hour while awake, oxygen titration to maintain saturation above 92 percent, and a repeat chest X-ray in the morning. He needs to be on telemetry given his cardiac history. The next set of vital signs is due at 2200."
Variants and adjacent tools: I-SBAR-R, I-PASS, ISOBAR
Several variants of the four-letter SBAR have been developed for specific contexts. I-SBAR-R, used widely in Australia and New Zealand and increasingly in UK trusts, prepends Identify (the speaker, the receiver, the patient) and appends Read-back (the listener repeats the recommendation to confirm receipt). The Read-back element addresses the closed-loop communication recommendation in the patient-safety literature.
I-PASS, developed at Boston Children's Hospital and tested in a multi-centre paediatric residency study published in the New England Journal of Medicine in 2014, expands the structure for resident-to-resident handoffs: Illness severity, Patient summary, Action list, Situation awareness and contingency planning, and Synthesis by receiver. The 2014 trial showed a 23 percent reduction in medical errors and a 30 percent reduction in preventable adverse events at participating sites. I-PASS is the dominant tool in US graduate medical education.
ISOBAR, used in some Australian hospitals, expands the structure to Identify, Situation, Observations, Background, Agreed plan, and Read-back. The expansion makes the structure slightly heavier than SBAR but increases the explicit safety-net steps.
The structured-communication family also includes the five Ps (Patient, Plan, Purpose, Problems, Precautions) used in some shift-change handoffs and the SHARQ format (Situation, History, Assessment, Recommendation, Questions) used in some critical-care contexts. None of these tools displaces SBAR; they apply the same underlying structured-communication principle to specific clinical contexts.
Why SBAR helps: the handoff-failure literature
The Joint Commission's sentinel-event database has consistently identified communication failures as a contributing factor in over half of all reported sentinel events, and handoff communication has been one of the most frequently cited specific failure types. The structured-communication literature traces handoff failures to four typical mechanisms: information omission (the receiver does not learn something the sender knew), information distortion (the receiver learns something different from what the sender said), interruption-related loss (the handoff is interrupted and the conversation does not resume completely), and hierarchy-related withholding (a less senior speaker fails to escalate concerns to a more senior listener).
SBAR addresses each mechanism. The standardised structure reduces omission by giving the speaker a checklist of categories. The named Assessment and Recommendation portions reduce distortion by forcing the speaker's interpretation and request into explicit form. The brevity of the format reduces the likelihood of interruption-related loss. The named Recommendation portion creates a low-friction path for less senior speakers to make explicit requests of more senior listeners, which addresses the hierarchy-related withholding mechanism the patient-safety literature has documented.
Where SBAR communications most often go wrong
Three failure modes appear in audits of SBAR nursing communications. The first is an Assessment portion that lists data without an interpretation; this is the most common failure in pre-licensure transcripts and is the failure mode that converts a structured handoff back into an unstructured one. The second is a Recommendation portion that ends with an open-ended question instead of a specific request; this is appropriate when the speaker does not yet know what is needed but is a sign of underprepared communication when the speaker does know. The third is a Background portion that includes the entire chart instead of the slice that explains the Situation; this dilutes the structure and lengthens the call past the point at which the listener can hold all of it in working memory.
Reader questions about SBAR
What is SBAR in nursing?
SBAR is a structured handoff and escalation tool that names four sections: Situation, Background, Assessment, and Recommendation. It was developed by the United States Navy submarine fleet in the 1990s, adapted for healthcare by Kaiser Permanente in 2002, and is now embedded in The Joint Commission patient-safety goals and the World Health Organization handoff communication framework. SBAR gives nurses a low-friction template to escalate a deteriorating-patient call to a physician and to transmit a clear clinical picture between shifts without losing critical information at the verbal handoff.
What are examples of SBAR?
A bedside escalation example: 'Situation, Mrs. Lin in 412 has a respiratory rate of 28 and saturation of 88 percent on 2 litres. Background, she is a 78-year-old admitted yesterday with community-acquired pneumonia, on ceftriaxone and azithromycin. Assessment, I think she is decompensating, possible early sepsis. Recommendation, I would like you to come and assess her now and consider escalating oxygen and fluids.' The four lines map exactly to S, B, A, R and take less than a minute to deliver over the phone.
What are the 4 components of SBAR?
The four components are Situation, Background, Assessment, and Recommendation. Situation states the patient and the immediate concern in one sentence. Background gives the relevant medical history, the admission diagnosis, and any current treatments. Assessment is the nurse's clinical judgement about what is happening, including a working diagnosis or differential, not a paraphrase of the data. Recommendation states the action requested and a time frame. The four-part order is fixed because it walks the listener from situation to ask in the cognitive order they need.
How do you write a SBAR report?
Write SBAR in four short paragraphs, one per letter, in the order S, B, A, R. Lead the Situation with the patient name, location, and the single immediate concern. Keep Background to the admission diagnosis, relevant chronic conditions, and current treatments tied to today's clinical picture. Make the Assessment a clinical judgement, not a data dump, even if tentative. Close the Recommendation with a specific action and a time frame, not a general request for help. The whole report should fit on one phone call or one handoff card.
What are the 4 types of nursing assessments?
The four types of nursing assessments most often tested are initial (or comprehensive admission), focused (problem-specific), time-lapsed (re-evaluation across a shift), and emergency (rapid primary survey). The initial assessment establishes a full baseline; the focused assessment investigates a single chief complaint; the time-lapsed assessment re-measures previous data points to track trends; the emergency assessment uses Airway, Breathing, Circulation, Disability, and Exposure to triage immediate threats. SBAR can carry any of the four types when their findings need to be communicated up the chain.
