Hospitalists and Antibiotic Stewardship: The 2017 Consensus Guidance

Antibiotic resistance is one of the defining clinical problems of the twenty‑first century, and nowhere is the response more visible than in the hospital ward. Misuse of broad‑spectrum agents drives resistant organisms such as methicillin‑resistant Staphylococcus aureus, vancomycin‑resistant enterococci, and extended‑spectrum beta‑lactamase producers, all of which lengthen inpatient stays and inflate the cost of care. Hospitalists sit at the intersection of admission, daily review, and discharge planning, giving them a unique vantage point to shape prescribing behaviour. The 2017 consensus guidance recognised this position and translated antimicrobial stewardship principles into a workflow that fits a hospitalist's daily round rather than an infectious‑disease specialist's consult.

Released alongside the Hospital Medicine 2017 meeting in Las Vegas, the document offered practical, ward‑level direction that complemented the more strategic frameworks issued by bodies such as the Australian Commission on Safety and Quality in Health Care. It focused on the prescribing moment, the documentation moment, and the review moment, and it gave frontline clinicians language to discuss de‑escalation with confidence. For Australian hospitalists working in mixed medical and surgical units, the guidance remains a useful reference point because it treats stewardship as a core clinical skill rather than an add‑on administrative task.

Origins and scope of the consensus

The consensus was developed by a writing group of hospitalists, infectious‑disease physicians, pharmacists, and microbiologists convened under the Society of Hospital Medicine. Their remit was deliberately narrow: to produce a statement that practising clinicians could carry into a morning handover and apply before the afternoon antibiotic timeout. The authors reviewed the available evidence on antibiotic use in common inpatient syndromes, including community‑acquired pneumonia, urinary tract infection, skin and soft tissue infection, and intra‑abdominal sepsis, and weighed it against real‑world prescribing patterns captured in the United States Centers for Disease Control and Prevention's antimicrobial use and resistance modules.

A defining feature of the document was its emphasis on the 48‑hour review. Rather than calling for a complete overhaul of empiric therapy at the point of admission, the guidance encouraged hospitalists to revisit every antibiotic order once culture, susceptibility, and clinical response data became available. The message was that stewardship is iterative, and that the prescriber who orders the drug bears responsibility for the decision to continue, narrow, broaden, or stop it. This framing aligned well with Australian practice, where ward pharmacists at hospitals such as the Royal Melbourne and Royal Prince Alfred already flag prescriptions for review at the second daily medication round.

Core principles for the prescribing hospitalist

Three principles anchor the consensus. The first is appropriate indication: every antibiotic order should be tied to a documented or strongly suspected infection, and a clear plan for duration should appear in the notes. The second is timely de‑escalation: once a pathogen is identified, the regimen should be narrowed to the most targeted, least toxic, and least costly agent that will treat the infection reliably. The third is accountability: the prescriber, the pharmacist, and the microbiology service share ownership of the antibiotic plan, and the hospitalist acts as the conductor of the team.

A second theme, less visible in older stewardship literature, was the role of communication. The guidance encouraged hospitalists to discuss antibiotic plans with patients and families in plain language, including the rationale for choosing a particular agent and the expected course of treatment. In Australia, where shared decision making is embedded in the National Safety and Quality Health Service Standards, this element of the consensus found a comfortable home. Conversations about why a child with otitis media might not need antibiotics, or why an elderly resident of a Sydney aged care facility is being switched from intravenous to oral therapy, became a routine part of the daily round.

Local realities for Australian hospitalists

Australian hospitals operate within a regulatory and funding environment that shapes how stewardship plays out at the bedside. The Pharmaceutical Benefits Scheme subsidises most antibiotics, and Schedule 4 listings mean that prescribers can choose from a wide range of agents without seeking special authority, which carries both freedom and responsibility. The Therapeutic Guidelines, known colloquially as eTG, provide a national prescribing reference that is widely respected and increasingly integrated into hospital electronic medical records. Aligning the 2017 consensus with eTG recommendations is rarely difficult, because both documents favour narrow‑spectrum first‑line therapy and explicit duration.

Geography adds another layer. Hospitalists in tertiary centres in Brisbane, Perth, and Adelaide work alongside infectious‑disease teams and antimicrobial pharmacists, while their colleagues in regional Western Australia or rural Victoria often cover larger caseloads with less specialist support. Telehealth infectious‑disease consults, funded through Medicare, have partly closed that gap, and the consensus document's emphasis on structured, repeatable review steps lends itself well to remote collaboration. Seasonal factors also matter: northern Australian hospitals see higher rates of melioidosis and leptospirosis during the wet season, which influences empiric choices in tropical Cairns or Townsville in ways that differ from the temperate south.

Translating the guidance into a daily routine

Putting the consensus into practice does not require new technology or new committees. A workable approach is to add a brief antibiotic review to the morning round, focusing on three questions: Is the indication still present? Have culture results arrived, and do they support narrowing? Is the planned duration written in the chart? This structure mirrors the "four moments of antibiotic decision making" model that the consensus endorsed, and it can be completed for an entire unit in fifteen to twenty minutes.

Documentation matters as much as the decision itself. The guidance encouraged hospitalists to record a "stop date" or "review date" on every antibiotic order, in the same way that a procedure consent form records an expected recovery. Linking the order to an indication in the electronic medication record, a practice already mandatory in many Australian public hospitals, allows the pharmacist to verify alignment with the treatment plan without paging the prescriber. Education of junior medical officers rotating through terms in medicine, surgery, and emergency remains the single most effective lever, and the consensus framing gives supervisors a shared script for teaching.

Comparing the 2017 framework with earlier guidance

The table makes clear that the 2017 document shifted stewardship from a system‑level gatekeeping function to a clinician‑level reflective practice. Australian hospitals that had already adopted indication‑linked prescribing and antimicrobial pharmacist review found the consensus easy to absorb, while smaller sites used it as a roadmap to strengthen their existing programmes.

Practical recommendations for ward teams

• Add an "antibiotic review" line to the ward round checklist, with the registrar confirming indication, culture data, and planned duration for every patient on an antimicrobial.
• Pair every empiric order with a stop or review date, defaulting to seven days unless a clear longer course is justified and documented.
• Use Therapeutic Guidelines and local antibiograms to drive de‑escalation, and document the rationale when a broader agent is continued despite susceptible cultures.
• Schedule a short, recurring tutorial with the hospital pharmacist for junior doctors, using recent cases to illustrate the four moments of decision making.
• Audit one syndrome per quarter, such as community‑acquired pneumonia or catheter‑associated urinary tract infection, and feed results back to the unit within four weeks of the audit close.

Hospitals that have built these habits into routine work report measurable reductions in total antibiotic days, fewer Clostridioides difficile infections, and shorter lengths of stay, while maintaining or improving clinical outcomes. The Australian experience mirrors international data, and the 2017 consensus provides a vocabulary and a structure that hospitalists can adapt to local protocols, funding rules, and patient populations. The document remains relevant because it treats prudent antibiotic use as a daily clinical discipline, one that begins with a thoughtful first dose and ends only when the prescriber has actively decided that the drug is no longer needed.
