Title: The Effect of Liberal vs. Restrictive Transfusion Strategies on Rehabilitation After Hip Fracture Surgery
Brief Summary: To examine the effect of two different transfusion regimens on rehabilitation after hip fracture surgery.


Options:
A: Inclusion Criteria:

* \>20% TBSA burn with anticipated operation need on admission as determined by attending physician
* age \>18 years
* Admission within 96 hours of injury

Exclusion Criteria:

* \<18 years of age
* pregnancy
* inability or unwillingness to receive blood products
* history of chronic anemia (hemoglobin \<9.0 g/dL one month prior to enrollment)
* preexisting need for hemodialysis
* brain death or imminent brain death
* non-survivable burn as determined by the attending burn surgeon
* angina or acute myocardial infarction
* preexisting hematologic disease
* Length of hospital stay anticipated to be \< 2 weeks
* Transfusion administered at outside hospital before admit
B: Inclusion Criteria:

* Primary hip fracture
* capable of informed consent
* independently dwelling
* able to ambulate independent of human assistance
* no active heart condition defined as no AMI within 3 months, no unstable angina or present incompensation/pulmonary oedema
* no regular transfusion demand or terminal disease.

Exclusion Criteria:

* Multiple fractures
* postop. immobilization due to to surgical reasons
* patient refusal to participate in relevant rehabilitation
* reoperation within 4. postoperative day.
C: Inclusion Criteria:

1. Age ≥18 years old at time of SAH
2. First ever episode of aneurysmal SAH
3. Diagnosis of aSAH as confirmed by treating physician (eg: neurosurgeon or neuro- interventionalist) and supported by blood in subarachnoid space (e.g. cranial imaging or cerebrospinal fluid positive for xanthochromia, surgical visualization) that is the result of a ruptured aneurysm (e.g. direct visualization, cranial imaging or catheter angiogram)
4. Hb ≤100g/L within 10 days following aSAH (defined by first day of hospital presentation)

Exclusion Criteria:

1. Physician and or family decision to withdraw/withhold active medical care at time of enrolment
2. Active bleeding with hemodynamic instability at time of enrolment
3. Patients with contraindication or known objection to blood transfusions
4. SAH due to mycotic aneurysm, infundibulum and vascular malformations.
D: Inclusion Criteria:

* Has undergone surgical repair for a hip fracture
* Has a postoperative Hgb level below 10 g/dL within three days of surgery
* Diagnosis of cardiovascular disease (e.g., coronary artery disease, congestive heart failure, stroke or transient ischemic attack, or peripheral vascular disease) or cardiovascular risk factors (e.g., diabetes mellitus, hypertension, hypercholesterolemia, tobacco use, or creatinine levels greater than 2.0 mg/dL)

Exclusion Criteria:

* Unable to walk prior to hip fracture
* Declines blood transfusions
* Suffered multiple traumas
* Pathologic fracture of the hip due to malignancy
* Clinically recognized acute myocardial infarction within the 30 days prior to study entry
* Previously participated in the trial and fractured the other hip
* Symptoms associated with anemia (e.g., ischemic chest pain) or actively bleeding at the time of randomization

Answer: B
