Budget impact analysis of durvalumab consolidation therapy vs no consolidation therapy after chemoradiotherapy in stage III non-small cell lung cancer in the context of the Chilean health care system.
Article in PloS one, 2024. 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
backgroundDurvalumab, used as consolidation immunotherapy, has shown to improve survival in patients with stage III non-small cell lung cancer who respond to chemoradiotherapy, based on the most recent follow-up of PACIFIC. The Chilean healthcare system provides access to certain immunotherapies for this condition. The present study sought to estimate the budget impact of durvalumab versus standard of care in the context of the Chilean healthcare system. RESEARCH DESIGN AND
methodsA partitioned survival model was adapted to compare two strategies: durvalumab as consolidation therapy and standard of care for treating stage III NSCLC. The number of patients eligible for treatment was estimated using published incidence data and modeled for a 5-year time horizon. Model inputs were based on published literature, and the duration of treatment was estimated using survival curves obtained from PACIFIC. Costs were estimated in Chilean pesos (CLP) and converted to USD dollars using an exchange rate of USD 1 = CLP 827. Scenario analyses were performed to assess different subsequent therapy splits, variations in the target population and dosage of durvalumab.
resultsDurvalumab uptake projected total costs ranging from USD 1.27 in Year 1 to 8.5 million in Year 5 from the public perspective. From the private perspective, the budget impact for the first year is USD 1.3 million to USD 3 million for 2028. This difference relies mostly on the lower number of patients treated. Both perspectives anticipated cost savings over the time horizon through reduced monitoring, adverse events, and end-of-life expenses.
conclusionsThis study demonstrates that the inclusion of Durvalumab for NSCLC in Chile represents an investment in the Chilean health system. The incremental costs align with clinical benefits and potential savings in healthcare resource utilization. However, a comprehensive cost-effectiveness analysis is needed to evaluate its economic value thoroughly.
