Brief summary
A within-trial economic evaluation of the multicenter HAPPEN cluster trial found that an enhanced inpatient oral care protocol was economically dominant, generating cost savings of AUD $152 and gaining 0.02 QALYs per patient by reducing non-ventilator hospital-acquired pneumonia.
What NurseJet pulled from the source
Non-ventilator hospital-acquired pneumonia (NV-HAP) is one of the most common and expensive healthcare-associated infections, yet nurse-delivered oral hygiene is frequently deprioritized on busy medical-surgical wards. Investigators performed a within-trial economic evaluation of the multicenter HAPPEN cluster randomized trial across three Australian acute-care hospitals. Evaluating outcomes from a hospital perspective using an intention-to-treat framework, a cohort-level decision-analytic model integrated intervention rollout and supply costs against NV-HAP acute treatment and saved hospital bed-days (valued in 2025 Australian dollars [AUD]). In a modeled cohort of 1,000 patients, total costs under usual care were AUD $12,148,000 compared to AUD $11,996,000 with the enhanced oral care program. The intervention saved an average of AUD $152 and yielded 0.02 quality-adjusted life-years (QALYs) gained per patient, confirming the protocol as dominant (cheaper and more effective). The incremental net monetary benefit was AUD $642 per patient (95% uncertainty interval: AUD $42 to AUD $1,591). Probabilistic sensitivity analysis demonstrated a 98% probability that enhanced oral care was cost-effective at a threshold of AUD $28,000 per QALY.
Why this matters for nurses
Infection preventionists and medical-surgical nurse leaders often struggle to secure administrative resources and protected nursing time for basic oral hygiene on general wards. Demonstrating that systematic, twice-daily oral care is not only clinically protective against NV-HAP but also cost-saving gives nurses compelling financial and outcome evidence to institutionalize oral care bundles as core quality-improvement priorities.
Bedside takeaway
A within-trial economic evaluation of the multicenter HAPPEN study found nurse-delivered enhanced oral care was dominant and cost-saving, saving AUD $152 and adding 0.02 QALYs per inpatient by preventing NV-HAP.
Key takeaways
- Within-trial economic evaluation of the multicenter HAPPEN cluster randomized trial modeled 1,000 inpatient admissions across 3 Australian hospitals.
- Nurse-delivered enhanced oral care was economically dominant, reducing total costs while improving health outcomes.
- The protocol produced average savings of AUD $152 and 0.02 QALYs gained per patient after accounting for prevented pneumonia bed-days.
- Incremental net monetary benefit was AUD $642 per patient, with a 98% probability of cost-effectiveness at an AUD $28,000/QALY threshold.
- Findings provide rigorous health-economic justification for nursing leadership to fund oral hygiene supplies and protected shift time for inpatient oral care.
Practice implications
- Perform oral cavity assessments upon admission and at least daily; ensure every inpatient has functional toothbrushes, fluoride toothpaste, and chlorhexidine or mouth rinses per protocol; assist dependent and high-risk patients with assisted tooth brushing twice daily.
Limitations & cautions
- Economic model derived from three Australian hospitals with specific cost structures (AUD 2025); bed-day valuation and wage costs may vary in other international healthcare systems.
