Brief Summary:
The SAHaRA trial will clarify the role of treating anemia with Red Blood Cell (RBC) transfusion in a unique and vulnerable patient population, and determine whether that impacts on functional outcomes and mortality. It will guide best practice standards and clarify the optimal RBC transfusion strategy in patients with aSAH.

Condition or disease Intervention/treatment Phase
Subarachnoid Hemorrhage, Aneurysmal Other: Liberal RBC Transfusion Strategy Other: Restrictive RBC Transfusion Strategy Phase 3

Detailed Description:
We hypothesize that in adult patients suffering from aSAH and anemia, a liberal RBC transfusion strategy as compared to a restrictive RBC transfusion strategy decreases the combined rate of death and severe disability at 12 months (using the modified Rankin Scale)

Arm Intervention/treatment
Experimental: Liberal RBC Transfusion Strategy
Hemoglobin value of ≤100g/L
Other: Liberal RBC Transfusion Strategy
RBC transfusion is triggered by a Hemoglobin value of ≤100g/L

Active Comparator: Restrictive RBC Transfusion Strategy
Hemoglobin value of ≤80g/L
Other: Restrictive RBC Transfusion Strategy
Optional RBC transfusion is triggered by a Hemoglobin value of ≤80g/L




Primary Outcome Measures :
  1. Modified Rankin Scale (mRS) [ Time Frame: 12 months post ]

    The Modified Rankin Scale (mRS) is a functional outcome measure in stroke. The interview consists of five sections: Constant Care, Assistance to Attend to Bodily Needs/For Walking, Assistance to Look After Own Affairs, Usual Duties and Activities and Symptoms as a Result of Stroke.

    The scale is scored from 0 reporting no symptoms at all, to 5 reporting severe disability. Death is indicated by a score of 6.



Secondary Outcome Measures :
  1. Functional Independence Measure (FIM) [ Time Frame: 12 months post ]

    The Functional Independence Measure (FIM) assesses the level of a patient's disability considering the amount of support needed to care for them.Items are scored on the basis of how much assistance is required for the individual to carry out activities of daily living.

    The FIM is comprised of 18 items, grouped into 2 subscales - motor and cognition.

    Each item is scored on a 7 point ordinal scale, ranging from 1 to 7. The 2 subscales are then added to give a total FIM score between 18 and 126. The higher the score, the more independent the patient is in performing activities of daily living.


  2. EuroQOL Quality of Life Scale (EQ5D) [ Time Frame: 12 months post ]

    The EQ-5D measures generic health status. There are 5 dimensions: Mobility, Self-care, Usual Activities, Pain/Discomfort and Anxiety/Depression which are answered by 5 Problem Levels: None, Slight, Moderate, Severe and Unable. The result is a 5 digit number, 11111 indicating no problem in any dimension to 55555 indicating unable to complete in all dimensions.

    Quality of life is also assessed on a visual analog scale reported from 0 being the worst imaginable health status to 100 as the best imaginable health status.


  3. Red Blood Cell Transfusions [ Time Frame: up to 21 days ]
    The total number of red blood cell transfusions received.

  4. Daily Hemoglobin [ Time Frame: up to 21 days ]
    The lowest daily hemoglobin values.

  5. Transfusion-related Complications [ Time Frame: up to 28 days ]
    Complications such as Acute Respiratory Distress Syndrome (ARDS), cardiovascular failure, cardiac ischemia, deep venous thrombosis, pulmonary embolism, sepsis, and septic shock.

  6. Delayed Cerebral Ischemia and Vasospasm [ Time Frame: up to 28 days ]
    The incidence and severity of delayed cerebral ischemia and vasospasm.

  7. Cerebral Infarction [ Time Frame: up to 28 days ]
    The incidence of cerebral infarctions.

  8. Mechanical Ventilation [ Time Frame: up to 21 days ]
    If required, the duration of mechanical ventilation.

  9. Length of Stay [ Time Frame: 12 months post ]
    The length of ICU or hospital stay.

  10. Mortality [ Time Frame: 12 months post ]
    The number of deaths.
