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.

2. Capable and willing to consent
3. Non-cardiac/non-neurological surgery with expected hospital stay of at least 72 H
4. American Society of Anesthesiologists (ASA) physical status I-IV
5. English speaking
6. Willingness to use a provided tablet device
7. Willingness to commit at least 1 hour per day to experimental intervention (cognitive activity/exercise) to complete a minimum of 10 hours within at least 8 days prior to surgery.

Exclusion criteria

1. Severe visual or auditory deficits
2. Illiterate
3. Surgery within the previous 6 months requiring general anesthesia
4. Score \< 26 on initial Mini Mental Status Exam (MMSE - modified version) (24 for patients with less than high school education)
5. Positive pre-surgery Confusion Assessment Method test (CAM)
6. Active depression as indicated by Geriatric Depression Scale screening test (score ≥ 10)
7. History of Axis I or II psychiatric disorders including bipolar disorder, schizophrenia, dementia, alcohol or drug abuse
8. ASA physical status V, VI
9. Planned postoperative intubation
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:

* Diagnosis of cancer
* Age ≥ 18 yr
* Estimated prognosis of ≤ 1 week
* Patient unable to maintain sufficient oral intake (1L / day)

Exclusion criteria:

* Patient clinically dehydrated
* Patient has hyperactive delirium ("terminal agitation") at present
* Patient has had hyperactive delirium ("terminal agitation") in the last 24hr
* Clinical indication for clinically-assisted hydration (e.g. hypercalcaemia)
* Clinical contra-indication to clinically-assisted hydration (e.g. cardiac failure)
* Clinical contra-indication to peripheral cannulation
* Intravenous fluids / subcutaneous fluids / total parenteral nutrition (TPN) / enteral feeding or fluids already being administered
* Patient likely to be transferred to another setting for end of life care (e.g. home, hospice)
D: Inclusion Criteria:

• Eligible patients will be admitted acutely for a femoral neck fracture, a trochanteric or a subtrochanteric femoral fracture.

Exclusion Criteria:

* Hip fracture as part of multi-trauma or high energy trauma (defined as a fall from a higher level than 1 metre). One recent fracture in addition to the hip fracture (e.g. radius or shoulder) is acceptable.
* Regarded as moribund at admittance.
* Absence of a valid informed consent or assent.
