Rolling out modern sepsis bundles in a community hospital

Sepsis remains one of the most time-sensitive emergencies a clinician can face, with each hour of delayed antibiotic therapy associated with measurable increases in mortality. For community hospitals across Australia, the move from older 3-hour and 6-hour bundles to the consolidated Hour-1 bundle has changed both the rhythm of resuscitation and the choreography of the emergency department. The shift is not just about speed; it is about redesigning processes so that the right measure, the right fluid and the right drug are reliably delivered within sixty minutes of recognition.

The lessons shared at Hospital Medicine 2017 still resonate for hospitalists, ED consultants and nurses who run between rural triage rooms and tertiary corridors. Drawing on those conversations and on Australian safety programs, this guide walks through what the Hour-1 bundle actually requires, how to translate it into a workable local pathway, and how to keep it alive through audit, education and governance. Whether you work in a 40-bed facility in regional Queensland or a larger metropolitan service in Sydney or Melbourne, the same building blocks apply: a screening trigger, a multidisciplinary response, a clear documentation trail and a feedback loop that catches drift before patients do.

From the 2016 bundles to the Hour-1 framework

The Surviving Sepsis Campaign's 2018 update collapsed the previous 3-hour and 6-hour bundles into a single Hour-1 bundle, recognising that earlier completion of the same elements is feasible even outside intensive care. Lactate measurement, blood cultures, broad-spectrum antibiotics, the 30 mL/kg crystalloid bolus for hypotension or lactate ≥ 4 mmol/L, and the introduction of vasopressors for persistent hypotension are now expected within the first sixty minutes of recognition. The change moved sepsis care closer to the language already used in Australian EDs for stroke and myocardial infarction, where "time is tissue" is operationalised through standard order sets.

For clinicians used to the older framework, the most visible difference is the time pressure on antibiotics. Australian antimicrobial stewardship frameworks, administered through the Therapeutic Goods Administration and reinforced by local hospital pharmacy committees, support early empirical therapy but expect a documented indication, a planned review at 48 to 72 hours and a de-escalation strategy. The Hour-1 bundle does not override these requirements; it just requires that the first dose be given, not merely prescribed. A well-designed pathway treats the empirical dose as a stop-gap and the formal approval as a follow-up, so that neither stewardship nor urgency is compromised.

Mapping the bundle to local triage and ED workflows

Australia's emergency departments use the Australasian Triage Scale, and Category 1 and 2 patients who trigger a sepsis alert are the natural focus of any Hour-1 pathway. Embedding qSOFA or a modified SIRS check into the triage form, with a positive result automatically firing a sepsis call through the hospital's paging or messaging system, is often the single most effective change a community hospital can make. In NSW, the Clinical Excellence Commission's Sepsis Kills program has driven a similar approach for more than a decade, and parallel protocols exist in Queensland Health and Victoria's Safer Care Victoria. Hospitals do not need to reinvent these tools; they need to localise the screening criteria, the team composition and the escalation language.

Multidisciplinary ownership is the next step. A working group should include an ED consultant or FACEM, an intensive care liaison, a senior medical officer from general medicine, the antimicrobial stewardship pharmacist, a clinical nurse educator and a laboratory representative. In Perth and Adelaide, where smaller teams often cover both ED and inpatient duties, the same individual may hold several of these roles, which makes a written escalation matrix even more important. A typical matrix defines who attends the bedside within ten minutes, who prescribes the first dose, who draws bloods and who notifies the patient's GP or the regional retrieval service if transfer is needed.

Education, simulation and credentialing the team

Education cannot be a one-off grand round. The most successful community hospitals run short, in-situ simulations every fortnight, using a manikin in an empty resus bay to walk through a septic patient from triage to antibiotic infusion. These sessions double as a stress test for the pathway itself: if nurses cannot find the antibiotic in the cupboard or if the lactate result takes longer than thirty minutes to return, that gap becomes a quality improvement target rather than a personal failing. Pairing simulation with the hospital's mandatory basic life support and advanced life support refreshers also keeps sepsis training inside the existing continuing professional development cycle that AHPRA-registered clinicians already complete.

Credentialing extends beyond doctors. New residents and RMOs should be observed completing their first sepsis bundle with senior support, and pharmacists should be trained to flag early prescriptions that breach local resistance patterns. The Hour-1 bundle is small in scope but unforgiving in timing, so the educational goal is muscle memory, not knowledge transfer. Teams that rehearse the steps under time pressure tend to keep bundle compliance above seventy per cent at audit, while those that rely on posters and e-learning modules drift back toward pre-bundle habits within months.

Measuring compliance, outcomes and antimicrobial use

Numbers matter because they expose the gap between intention and practice. A useful starting audit captures time to lactate, time to blood cultures, time to antibiotic, total fluid volume in the first hour, and in-hospital mortality for patients with septic shock. The table below sets the Hour-1 elements alongside the older 3-hour targets so that clinicians can see how the same actions have been tightened. A second audit, run three months later, should compare the same metrics after the pathway has been in place, and a third at twelve months should confirm whether compliance has held.

Pair these process measures with clinical outcomes: ICU admission rates, average length of stay for septic patients, days of mechanical ventilation and Clostridioides difficile rates linked to broad-spectrum use. Australian hospitals that publish their sepsis data, either internally through a clinical governance committee or externally through the Australian Commission on Safety and Quality in Health Care, generally see faster improvement because staff can compare their unit against a peer benchmark rather than an abstract standard.

Embedding the pathway through governance and digital tools

A pathway that lives only on a wall poster will fade. Hospitals that succeed treat sepsis as a standing item on the morbidity and mortality meeting, with a named clinical lead who presents the latest dashboard and a written action list. Digital tools accelerate this loop. Many Australian services now embed the Hour-1 bundle as an order set inside the electronic medical record, with time-stamped prompts that nudge nurses to draw bloods and doctors to review antibiotics at 48 hours. Where electronic systems are limited, a paper checklist clipped to the bedside folder still works, provided the audit team collects completed forms and feeds the data back to the ward each month.

Sustaining change also depends on the network around the hospital. Rural and remote services can use the Royal Flying Doctor Service or state-based telehealth lines for sepsis consults when on-site intensive care cover is not available, and hospital-in-the-home programs in cities such as Brisbane and Hobart can safely step down stable patients once source control is achieved. The Hour-1 bundle is the front door of that journey; the rest of the system must be ready to receive the patient on the other side.

Practical components and rollout checkpoints

Bundle components to lock into your protocol

• Lactate measurement, blood cultures and empirical broad-spectrum antibiotics given within 60 minutes of recognition
• 30 mL/kg crystalloid initiated within the first hour for hypotension or lactate ≥ 4 mmol/L
• Vasopressors started within the first hour if hypotension persists during or after fluid resuscitation
• Documented source control plan and 48-hour antibiotic review by a stewardship pharmacist

First 90 days of implementation

• Establish a multidisciplinary sepsis working group with a named clinical lead
• Map current workflow against Hour-1 targets and identify the largest time gap
• Run fortnightly in-situ simulations on the ED floor and capture action items
• Audit baseline compliance, then repeat at 3 and 12 months and feed results back to staff

What every hospitalist should carry away from this is a sense of how small, deliberate changes stack up. A clearer triage prompt, a rehearsed team response, a tight antibiotic window and a dashboard that names the gaps will move sepsis care further than any single new drug. Community hospitals in Australia already have the clinicians, the safety programs and the audit structures to deliver the Hour-1 bundle reliably; the task now is to align those assets so that every septic patient meets the same sixty-minute standard, regardless of postcode.
