The growing pains of the 2024/2025 Portugal's NHS telephone triage system national rollout.
Article in Frontiers in public health, 2025. 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
In 2024, the Portuguese NHS introduced "Ligue Antes, Salve Vidas" ("Call Before You Go, Save Lives"), making phone triage through the national SNS 24 line compulsory prior to an Emergency Department (ED) visit in most NHS Local Health Units. While the policy was rightfully concerned with improving timely access to urgent care, it was quickly rolled out without a corresponding investment in infrastructure. The phone triage system's ability to meet growing call demand was assessed using full population administrative data (January 2024-May 2025), applying a Holt-Winters model to project call volumes. These demand forecasts were compared with a fixed benchmark of installed capacity, allowing for the estimation of unmet demand and waiting times. The authors' projections show that, without structural reinforcement, the SNS 24 line will face persistent overload, with up to 1 million unanswered calls during the 2025-26 winter season. Unless structural adaptations are implemented, current gaps threaten clinical safety, equity, and public trust. Robust policy options like AI-supported triage, targeted workforce reinforcement, and enhanced transparency are critical to ensure system resilience.
