Title: Functional Outcomes in Cardiovascular Patients Undergoing Surgical Hip Fracture Repair (FOCUS)
Brief Summary: The purpose of this study is to compare liberal red blood cell transfusion therapy with restrictive red blood cell transfusion therapy in surgical patients with cardiovascular disease or risk factors.


Options:
A: Inclusion Criteria:

* Age equal to or greater than 18 years
* Moderate or severe traumatic brain injury, defined as Glasgow coma scale less than or equal to 12 at hospital admission
* Hemoglobin lower than 9.0 g/dL within 7 days from hospital admission

Exclusion Criteria:

* Glasgow coma scale equal to 3 with dilated pupils bilaterally
* Previous neurological sequelae
* Pregnant women
* Jehovah's Witnesses
* Hemorrhagic shock at randomization
* Moribund patients
* Unable to provide consent
B: 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
C: 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.
D: Inclusion Criteria:

* Patients ≥ 70 years of age scheduled for intermediate- or high-risk non-cardiac surgery will be registered
* Registered patients will be randomised only if they indeed develop severe anaemia (if Hb level falls ≤ 9 g/dl) during surgery (=day 0) or day 1, 2, or 3 after surgery

Exclusion Criteria:

* preoperative Hb level ≤ 9 g/dl
* chronic kidney disease requiring dialysis
* suspected lack of compliance with follow-up procedures
* participation in other interventional trials
* expected death within 3 months
* inability to provide informed consent with absence of a legally authorised representative/ legal guardian
* temporary inability to provide informed consent
* previous participation in our trial
* patients who are prevented from having blood and blood products according to a system of beliefs (e.g. Jehovah's Witnesses)
* preoperative autologous blood donation.
