BACKGROUND: Hospital-acquired infections impose substantial clinical and economic burdens but are preventable. Although economic evaluations can show decision-makers which programes will generate the most health benefits per dollar invested, their representation amongst published evidence is unclear. This study identified infection prevention practices implemented in Singapore and assessed the availability of supporting economic evidence.
METHODS: Five infection prevention nurses identified implemented practices. Three were selected: automated surveillance, portable high-efficiency particulate air filters, and Ultraviolet-C disinfection machines. PubMed records from 2015 to 2025 were analyzed using bibliometric software to map keyword frequencies across five themes: cost-effectiveness, clinical, science and technology, environmental health, and the COVID-19 pandemic.
RESULTS: Cost-effectiveness-related keywords averaged fewer than 6 per year, compared with over 100 to 400 per year for clinical, science and technology, and environmental themes. Pandemic-related keywords increased from 2020 and still exceeded cost-effectiveness terms, with 12 to 18 per year.
DISCUSSION: Cost-effectiveness-related keywords were rare compared with other themes across all 3 infection prevention and control (IPC) practices. This suggests that published economic evaluations remain scarce even when interest in IPC interventions is heightened.
CONCLUSIONS: The lack of cost-effectiveness evidence indicates that IPC adoption might be informed by clinical and technical considerations rather than published economic appraisals. Broadening the use of economic evaluation might be warranted.
