Estimation of 'spectrum value': A discrete choice experiment to investigate the willingness-to-pay for narrow-spectrum based on other antimicrobial characteristics.
Article in Applied health economics and health policy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNarrow-spectrum antimicrobials are likely to drive fewer antimicrobial resistances. However, they may be more expensive than broad-spectrum alternatives.
objectiveTo determine the preferences of antimicrobial stewardship (AMS) experts regarding antimicrobial choice relative to relevant pharmacological and economic attributes, and how those attributes impact their willingness-to-pay for narrow-spectrum of activity.
methodsTwo discrete choice experiments (DCEs), consisting of six pharmacological and economic attributes, were administered via an online survey to Australian infectious disease physicians, clinical microbiologists and hospital AMS pharmacists. Respondents were asked to complete each DCE from a public hospital perspective, assuming 100 or 1000 patients would be treated each year, respectively. A conditional logit model was used to analyse the DCE data.
results155 respondents participated in one or both DCEs. Antimicrobial price, spectrum of activity, administration route, and public funding significantly affected drug choice in both scenarios (p < 0.001). Whether the antimicrobial was a novel class did not significantly impact choice. As the price of a narrow-spectrum antimicrobial increased, it became less preferred compared to a broad-spectrum cheaper alternative. With all other attributes being equal, participants were willing to pay an additional AU$862 for the narrow-spectrum option (95% CI $726-$998).
conclusionsWhile narrow-spectrum antimicrobials are preferred for targeted therapy by health practitioners with AMS expertise, price significantly influenced drug choice. Willingness-to-pay values reflect the knowledge and experience of AMS experts who are best-placed to gauge the opportunity costs of paying more for narrow-spectrum antimicrobials. These findings can inform the quantification of spectrum-value for health-system funding decisions.
