Details of the study

  • To determine if a care bundle (including early blood pressure control, hyperglycaemia, pyrexia, and abnormal coagulation management) improves functional outcome at 6 months in patients with acute spontaneous intracerebral haemorrhage presenting within 6 hours of symptom onset.

Study design

  • Class Of Evidence
    • Stepped wedge cluster randomised controlled trial
  • Randomisation
    • Central randomisation using permuted blocks to three sequences, stratified by country and projected patient numbers
  • Number Of Patients
    • 7036 (3221 intervention, 3815 control)
  • Length Of Follow Up
    • 6 months
  • Number Of Centres
    • Not stated in the paper
  • Stratification
    • Country and projected patient numbers
  • Outcome Measures
    • Functional outcome at 6 months

Results

  • Systolic blood pressure target <140 mm Hg reached in 96.7% of care bundle patients versus 94.4% of usual care patients.
  • Blood glucose target reached in 13.4% of care bundle patients versus 6.5% of usual care patients.
  • Temperature target (≤37.5°C) reached in 86.5% of care bundle patients versus 83.8% of usual care patients.

Conclusion

  • The care bundle protocol improved functional outcome at 6 months.

Critique

  • Conducted in diverse healthcare settings across 10 countries.
