Reducing Rapid Response Calls Through Root Cause Patterns

Rapid response calls are visible events, but they are rarely the beginning of a patient’s deterioration. Long before a medical emergency team arrives, a patient may show changes in respiratory rate, mobility, urine output, cognition, blood pressure or nursing concern. The call is often the final signal in a chain of missed, delayed or poorly connected observations.

At Hospital Medicine 2017, held from 1–4 May at Mandalay Bay Resort and Casino in Las Vegas, hospitalists and other healthcare professionals examined practical approaches to patient safety, clinical decision-making, research and continuing education. The discussions were relevant to any hospital trying to understand why an escalation occurs, rather than simply counting how often the emergency bell rings.

For Australian hospitals, the language may be slightly different. A ward team might call a medical emergency team, or MET, rather than a rapid response team. The setting could be a large tertiary service in Melbourne or Sydney, a regional hospital in Townsville, or a smaller rural facility where senior review and retrieval capacity are limited overnight.

The central lesson is to treat every MET call as useful clinical intelligence. Reviewing the pattern behind the call can reveal gaps in observation, communication, staffing, equipment, escalation pathways and shared clinical judgement. That shifts the goal from suppressing calls to preventing avoidable deterioration while preserving a low threshold for urgent help.

See The Call As A Safety Signal

A high number of rapid response calls does not automatically indicate poor performance. A responsive ward may activate its escalation process early, preventing cardiac arrest, intensive care admission or prolonged recovery. A low number can be more concerning if staff hesitate to call or if recognition systems are unreliable.

Root cause review should therefore examine the patient’s trajectory. When did the first abnormal sign appear? Who noticed it? Was it documented? Did the responsible clinician receive the information? Was a plan made, and was that plan reassessed when the patient changed?

The review should also separate appropriate escalation from preventable delay. A patient with sudden airway compromise may need immediate intervention even when the team has followed every process correctly. Another patient may have had twelve hours of increasing oxygen requirements and repeated abnormal observations before anyone sought senior input. These are different safety stories and require different responses.

Identify Recurring Failure Patterns

Several causes appear repeatedly in deterioration reviews. Incomplete observations can hide a rising respiratory rate, while documentation may record a number without prompting a clinical response. Early warning scores can support judgement, but they cannot replace it, particularly in patients with chronic respiratory disease, neurological impairment or unusual baseline observations.

Workload and competing priorities also matter. Medication rounds, admissions, discharges and procedure preparation can make a subtle change in condition easier to overlook. New graduates, agency nurses and rotating junior doctors may be uncertain about who should be contacted, especially when local escalation policies are complex.

Communication failures form another recurring pattern. A nurse may raise concern during a busy ward round, but the concern is not clearly assigned to a doctor. A consultant may review a patient but leave no documented timeframe for reassessment. The consult communication lessons associated with the conference are useful here because clear ownership is a clinical intervention, not an administrative detail.

Improve Recognition Before The Emergency

The most effective response team is often the ward team that recognises risk early. Regular observations should include a deliberate scan for trends rather than isolated values. A respiratory rate that rises from 20 to 28 may matter even if the patient’s blood pressure remains acceptable. New confusion, reduced oral intake or an inability to mobilise can also signal infection, hypoxia, bleeding or medication toxicity.

Structured bedside huddles can make these changes visible. A short discussion at the start of a shift may identify patients with increasing oxygen needs, difficult fluid balance, recent surgery or a history of repeated escalation. It should also clarify ceilings of treatment and the patient’s wishes, so that urgent care is consistent with the agreed goals.

Australian hospitals commonly use observation and response charts adapted to local policy, including systems linked to MET criteria. The safest approach is to make the trigger easy to understand and the response equally clear. Staff should know whether a score requires a nurse-in-charge review, resident medical officer attendance, registrar review or immediate MET activation.

Education should focus on decisions, not just chart completion. Case-based training can show how a deteriorating patient presents differently in an oncology ward, emergency short-stay unit or aged-care transfer. It should reinforce that staff can escalate because they are worried, even when a numeric threshold has not yet been reached.

Build Reliable Escalation And Handover

A rapid response pathway works best when it is predictable. Each ward should know how to summon the team, what information to provide, who remains with the patient and how the event is handed back after stabilisation. Confusion about roles consumes time during a crisis and can leave important tasks unfinished.

The call itself should communicate a concise clinical picture: what has changed, the relevant background, current vital signs, interventions already attempted and the level of treatment considered appropriate. A structured format such as ISBAR can help, provided it is used as a thinking aid rather than a rigid script.

After the immediate event, the patient needs a documented plan. That plan should identify the next review time, monitoring frequency, treatment limits, outstanding investigations and the clinician responsible for follow-up. Without this step, a successful rescue can be followed by a second deterioration later in the shift.

Escalation also needs to work across professions and services. A patient moved from the emergency department to a medical ward may have a different risk picture from the one described at admission. Clear transfer information, timely imaging and pathology review, and direct contact with the relevant specialty reduce the chance that concern is lost between teams.

Use Data Without Blaming Staff

A useful review combines clinical records, staff accounts and system data. The chart may show delayed observations, while a nurse explains that the observation machine was unavailable or that a patient was repeatedly off the ward. A doctor may recall raising concern verbally, while the record contains no clear response. Each source adds part of the causal picture.

Teams can track the time from first abnormal sign to senior review, the proportion of calls preceded by abnormal observations, repeat calls for the same patient, unplanned intensive care transfers and cardiac arrests outside critical care. These measures should be interpreted alongside staffing, ward type, patient acuity and treatment goals.

The conference’s practical education also extended to documentation and hospitalist workflow. For teams working across different funding and coding systems, resources such as the observation status coding guide illustrate a broader principle: accurate classification and documentation influence how care is understood, measured and funded.

In Australia, public hospitals report through state and territory systems, while private hospitals operate within a different funding and governance environment. A metropolitan service may have a dedicated deterioration analytics team; a small hospital in the Pilbara may rely on telehealth support and retrieval coordination. Measures must be adapted to the local service instead of comparing unlike hospitals as though they have identical resources.

Turn Findings Into Ward Changes

Root cause analysis has little value if it produces a report that staff never see. Findings should be converted into a small number of practical changes, such as a clearer MET call process, a revised observation prompt, a protected senior review period or a standard post-call huddle.

Every action needs an owner, a time frame and a way to check whether it worked. If staff say that escalation is delayed because the on-call doctor is difficult to reach, the response might include a backup contact and an expected response time. If repeated events involve poor fluid balance monitoring, the intervention may be a bedside prompt, targeted education and a review of medical orders.

A useful improvement cycle revisits the same cases after several weeks. Teams can ask whether the intervention changed recognition time, reduced repeated deterioration or improved staff confidence. This approach is more informative than launching a broad campaign to “reduce MET calls” without checking whether earlier calls have actually prevented harm.

Practical Review Prompts

• What was the earliest measurable or reported sign of decline?
• Who first recognised the change, and how was it communicated?
• Was the escalation threshold clear to the staff on duty?
• Did the post-call plan specify ownership and review timing?

Useful Ward-Level Actions

• Display one simple escalation pathway at every clinical workstation.
• Include treatment ceilings in admission and transfer handovers.
• Review repeat MET calls in a multidisciplinary huddle.
• Give staff feedback when early escalation prevents serious harm.

Compare Response Models Carefully

The most appropriate model depends on patient mix, staffing, geography and access to critical care. A tertiary hospital in Brisbane may have an in-house intensive care outreach service, while a regional hospital in New South Wales may need a senior nurse, visiting doctor and retrieval service to work together. Both can provide safe escalation when responsibilities are explicit.

The comparison is not a case for calling the emergency team at every minor change. Excessive alarm can create fatigue, but fear of “overcalling” can be more dangerous. Staff need permission to escalate uncertainty, alongside a clinical response that assesses the patient respectfully and gives feedback.

Conference education on clinical updates, including the clinical updates resource, reinforces the value of translating evidence into bedside habits. For Australian services, that translation should account for local deterioration policies, nursing roles, rural access, Aboriginal and Torres Strait Islander patient needs, and the practical realities of care across state health networks.

What Teams Should Remember

Reducing rapid response calls should never be the sole target. The safer aim is to reduce preventable deterioration, shorten the time to appropriate review and ensure that every urgent call results in learning. Some calls will remain necessary, and an early MET activation may represent excellent care.

The strongest root cause reviews follow the patient’s story from the first change to the final intervention. They examine observation trends, workload, handover, escalation rules, clinical judgement and follow-up ownership without reducing the event to one person’s mistake.

For hospital teams, the lasting message from Hospital Medicine 2017 is straightforward: rapid response events are windows into the reliability of everyday care. Notice the pattern early, make escalation easy, and remember that the safest call is the one made before a crisis becomes irreversible.
