The Orpington Prognostic Score (OPS) assessed in the first week after stroke effectively predicts patient outcomes. However, it offers no significant advantage over the National Institute of Health Stroke Scale (NIHSS) at 24 hours for rehabilitation triage.

Area of Science:

  • Neurology
  • Rehabilitation Medicine
  • Clinical Prognostics

Background:

  • Accurate stroke outcome prediction is crucial for timely triage, family counseling, and resource allocation.
  • The Orpington Prognostic Score (OPS) is utilized in Calgary for rehabilitation triage but its one-week predictive accuracy is unassessed.
  • Existing prognostic scales require timely and simple application for clinical utility.

Purpose of the Study:

  • To evaluate the predictive capability of the first-week Orpington Prognostic Score (OPS) for stroke patient outcomes.
  • To compare the prognostic validity of the one-week OPS with the 24-hour National Institute of Health Stroke Scale (NIHSS).
  • To determine the optimal timing for prognostic assessment in stroke rehabilitation.

Main Methods:

  • Patients admitted to a sub-acute stroke unit were assessed using the OPS within the first week.

  • Logistic regression and receiver operator characteristic analysis were employed to compare the predictive validity of the one-week OPS against the 24-hour NIHSS.
  • The primary outcome measured was the final patient disposition (discharge home, death, or inpatient rehabilitation).

    • Main Results:

    • The first-week OPS demonstrated high predictive accuracy for final patient disposition.
    • No significant advantage was found for the one-week OPS compared to the 24-hour NIHSS in predicting outcomes.
    • Both the OPS and NIHSS showed equivalent prognostic value for stroke patients post-rehabilitation.

    Conclusions:

    • The Orpington Prognostic Score (OPS) obtained within the first week post-stroke is a reliable predictor of final outcome.
    • The National Institute of Health Stroke Scale (NIHSS) assessed at 24 hours provides comparable prognostic information to the first-week OPS.
    • Both scales can aid in guiding rehabilitation and resource allocation decisions for stroke survivors.
