A Community Hospital Implementation of a Mobile Preoperative Peripheral Nerve Block Service in Non-OR Environments for Hip Fracture Patients.

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 AND
objectivePeripheral nerve blocks (PNB) are recognized as best practice for managing pain in older adults with fragility hip fractures. Despite strong evidence, the adoption of PNB pre-operation has been slow due to several implementation barriers. This study addresses this gap by describing the co-design and implementation of a preoperative Mobile PNB Service led by anesthesiology in a Canadian community hospital. We aim to: (1) provide a transferable, anesthesia focused implementation roadmap; (2) identify key implementation activities that enable the delivery of PNBs outside the operating room; and (3) report formative feasibility and evaluation outcomes (blocks delivered, pain levels, adverse events, and opioids administered before and after block delivery.
methodsThe mobile PNB service is comprehensively described to enable replicability following the Template for Intervention Description and Replication (TIDieR) checklist. Key design and implementation activities are identified by matching the activities with theory informed implementation functions from the Behavior Change Wheel (BCW). The formative outcomes were tracked alongside block delivery and abstracted from the patients' chart.
resultsThe multidisciplinary team led implementation activities primarily targeted enablement, education, and environmental restructuring to support the capability, opportunity, and motivation to deliver nerve blocks. The Mobile PNB Service was implemented feasibly, 76 blocks were delivered (44% Emergency Department (ED) and 56% ward) and safely, no procedure-related adverse events were observed. Early implementation was associated with increased uptake of preoperative PNBs and substantial reductions in patient-reported mean (SD) pain scores following block delivery from 7.1 (2.6) pre-block to 1.0 (2.0) post-block, and reduction in mean (SD) opioid administration following block delivery from 0.64 (0.90 milligrams per hour of oral morphine equivalents pre-block to 0.22 (0.49) milligrams per hour post-block. DISCUSSION: This study provides a replicable, theory-informed roadmap for closing the gap between guideline-recommended PNB and their delivery in non-operating room settings. An anesthesiology-led Mobile PNB Service was successfully implemented by addressing known system- and provider-level barriers using implementation frameworks. These findings underscore the value of theory-guided service design to identify essential components that enable behavior change and expand access to evidence-based analgesia for hip fracture patients.
