Optimizing Antibiotic Strategies With a Clinical Pathway Approach: Enhanced Initiation and De-escalation in Community-Acquired Pneumonia.
Article in HCA healthcare journal of medicine, 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
Background: Community-acquired pneumonia (CAP) remains a leading cause of hospitalization, mortality, and health care expenditure worldwide. Inappropriate use of broad-spectrum antibiotics contributes to antimicrobial resistance, adverse drug events, and increased costs. Antibiotic stewardship and standardized clinical pathways are key strategies to improve prescribing practices. Methods: This quality improvement (QI) initiative was conducted at a 240-bed tertiary care teaching hospital from January 2023 through January 2025. A CAP-specific digital clinical pathway was developed using Curbside Health® and integrated into the electronic health record (EHR), accessible through a structured order set to support real-time clinical decision-making. The intervention included provider education and iterative refinement through 2 Plan-Do-Study-Act (PDSA) cycles. Community-acquired pneumonia cases were identified using ICD-10 coding and antibiotic order indication. Outcomes were analyzed at the system level using aggregated EHR data. Statistical analyses were performed using chi-squared, Fisher's exact, and Results: A total of 880 patients were included in the pre-intervention period and 1345 in the post-intervention period. Following implementation, broad-spectrum antibiotic use significantly decreased (vancomycin: 71.4% to 26.2%, Conclusion: Integration of a CAP-specific digital clinical pathway into the EHR was associated with improved antibiotic stewardship and reduced health care costs. These findings support the feasibility of EHR-embedded decision support tools to optimize antibiotic prescribing. Patient-level clinical outcomes and demographic data were not assessed, consistent with the system-level design of this QI initiative, which warrants further evaluation in future studies.
