Read the detailed description
This study, titled "Prehospital Rapid Evaluation and Detection in Cerebrovascular Triage: A Multicenter Study of Glial Fibrillary Acidic Protein Point-of-Care Testing and Handheld Near-Infrared Spectroscopy Technology (CEREBO) in India," aims to validate the PREDICT Assessment Model, which combines GFAP/D-Dimer point-of-care testing with handheld CEREBO Near-Infrared Spectroscopy (NIRS) technology for the rapid differentiation of ischemic stroke and intracerebral hemorrhage in the prehospital setting.
The study will be conducted under the Indian Council of Medical Research (ICMR) National Health Research Priority (NHRP) programme as part of the INDIA-EMS project and will use a two-phase design. Phase I is a prospective, multicenter validation and feasibility study involving patients with suspected acute stroke presenting by ambulance or directly to the emergency department. Participants will undergo clinical assessment, including BE-FAST and neurological assessment, finger-prick blood testing for GFAP/D-Dimer, and CEREBO-NIRS assessment. All participants will subsequently undergo standard diagnostic evaluation with a CT head scan, which will serve as the gold standard for stroke subtype classification. The diagnostic accuracy, feasibility, process times, and safety of the combined PREDICT Assessment Model will be evaluated.
Phase II will be a pilot randomized controlled trial evaluating the integration of the PREDICT Assessment Model into prehospital stroke pathways. Ambulance services within the catchment areas of CMC Ludhiana and JIPMER Puducherry will be randomized to intervention or control groups. In the intervention group, ambulance personnel will use GFAP/D-Dimer testing and CEREBO-NIRS technology to support prehospital stroke classification and triage, in coordination with the on-call stroke team. The control group will receive standard care, including transport to the hospital for CT-based diagnosis and subsequent treatment decisions.
The primary objective of the study is to validate the diagnostic accuracy and feasibility of the combined GFAP/D-Dimer and CEREBO-NIRS approach and to assess its potential impact on prehospital stroke triage. Phase II will additionally assess the effect of the intervention on the time from ambulance dispatch to initiation of stroke-specific treatment. Secondary outcomes include functional outcome at 90 days measured by the modified Rankin Scale, in-hospital mortality, and adverse events.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
GFAP/D-Dimer Point-of-Care Testing & CEREBO Near-Infrared Spectroscopy (NIRS)Diagnostic test
A finger-prick blood sample will be obtained from patients with suspected acute stroke and tested using a GFAP/D-Dimer lateral flow assay. The test will provide rapid biomarker results to support differentiation between ischemic stroke and intracerebral hemorrhage in the prehospital setting and The handheld CEREBO-NIRS device will be applied non-invasively to the patient's scalp to detect intracranial hematoma by assessing asymmetry in near-infrared optical density. The findings will be recorded and used as part of the PREDICT Assessment Model for stroke subtype classification.
CT HeadDiagnostic test
Standard care CT head imaging
| Study group | Role | What they receive |
|---|---|---|
| PREDICT Assessment Model | Experimental | Ambulances in the intervention group will use the GFAP/D-Dimer point-of-care test and CEREBO Near-Infrared Spectroscopy (NIRS) technology to classify suspected acute stroke in the prehospital setting. Patients suspected of ischemic stroke and large vessel occlusion will be rapidly triaged to a comprehensive stroke centre, while patients suspected of intracerebral hemorrhage will receive stringent blood pressure control in the ambulance according to established protocols. Decision-making will be undertaken in conjunction with the on-call stroke team through the PREDICT App. Receives: Diagnostic Test: GFAP/D-Dimer Point-of-Care Testing & CEREBO Near-Infrared Spectroscopy (NIRS) |
| Standard Care | Active comparator | Ambulances in the control group will follow standard care procedures, including rapid transport of patients to the hospital for CT head imaging, followed by treatment decisions based on the CT findings. Receives: Diagnostic Test: CT Head |
What is being measured
The primary outcome is the main question the study is designed to answer.
PREDICT assessment model

Measured: 30 mins
Time for Device Application by Paramedics
(Phase 1) The time taken by paramedics/ ED personnel to apply the CEREBO NIRS device and obtain GFAP/D Dimer results. Lesser time indicates good outcome.
Measured: 30 mins
Treatment initiation
(Phase 2) Time from Ambulance dispatch to initiation of stroke-specific treatment (Triage to Stroke ready centre or rapid BP control). Lesser time indicates better outcome.
Measured: 30 mins
Secondary outcomes (6)
Inter-Center Variability
(Phase 1) Comparison of diagnostic accuracy and feasibility metrics between CMC Ludhiana and JIPMER Puducherry to assess consistency across centres. More consistency indicates good outcome.
Measured: 2 years
Correlation with Gold Standard
(Phase 1) Agreement between the PREDICT assessment model and the CT head scan diagnosis (the gold standard). More correlation indicates better outcome.
Measured: 2 years
Safety Metrics
