Title: A Cluster Randomised Trial of Alternative Forms of Hydration in Cancer Patients in the Last Days of Life (Feasibility Study)
Brief Summary: It is unclear whether the use of fluids given by a "drip" is beneficial to cancer patients in the last days of life, and as a result many individuals do not receive such treatment (although they do receive fluids by mouth, and regular mouth care). The researchers want to undertake a large study ("main study") to determine the benefits of fluids given by a drip, but first need to undertake a small study ("feasibility study") to ensure that the main study can be done.

The feasibility study will be done in twelve units (hospitals, hospices) in England \& Wales; each unit will be allocated a treatment at random, and all patients in the unit will receive that treatment (if appropriate). Standard treatment A consists of drinking fluids (if possible), regular mouth care, and treatment of any symptoms; standard treatment B consists of drinking fluids (if possible) , regular mouth care, fluids by a drip, and treatment of any symptoms.

Patients will be assessed on a four hourly basis, and any uncontrolled symptoms will be recorded. The main symptom of interest is agitation ("delirium"), which has multiple causes, including dehydration and kidney failure. Uncontrolled symptoms will be appropriately treated, e.g. patients with pain will be given painkillers. Equally, problems relating to the fluids given by a drip will also be recorded. Involvement in the study will not interfere with the patient's general care, and there will be no additional blood or other tests.


Options:
A: 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.
B: Patient Inclusion Criteria: medical patients who: are age ≥65, speak English or Spanish, live in the community prior to admission to the hospital, screen positive for dementia on well-validated scales (Montreal Cognitive Assessment {MoCA} ≤ 25 123-127 and AD8 \>2 128,129), and score 0.5 to 2.0 on the Clinical Dementia Rating Scale; and have a family CG as the designated study partner for the duration of the study.

Patient Exclusion Criteria: mild cognitive impairment (CDR 0.5 without functional or ADL impairments), severe dementia (CDR 3), any significant neurological condition associated with cognitive impairment other than dementia (e.g. brain tumor), a major acute psychiatric disorder, have no family caregiver to participate, are enrolled in hospice and/or have a life expectancy of six months or less, are admitted from a nursing home, or experience transfers to another unit for stays longer than 48 hours.

Family Inclusion Criteria: age 18 and above whose relatives meet inclusion criteria will be eligible if they can speak and read English or Spanish; and are related to the patient by blood, marriage, adoption, or affinity as a significant other (defined as or by the patient/legally authorized person as the primary person providing oversight and support on an ongoing basis); participate, at a minimum, in the initial assessment and development of FamPath; and able to recall at least two words on the MiniCog

Staff nurses (at the conclusion of the intervention at each site) who identify the intervention unit as the primary unit worked, and speak English or Spanish, will be included in focus groups

For the exploratory aim of assessing the cultural appropriateness of the intervention, we will recruit family caregivers who self-identify as black, Latino, Asian and white, randomly selected from the Fam-FFC sample. Approximately 10 percent of families from each ethnic group represented in the study will be approached for consent for participation in interviews. (If theoretical saturation is not reached, interviews will continue until saturation is reached). Additionally, the six nurse champions will be consented and interviewed after the study ends in his/her particular unit/setting to provide their perspective on the cultural appropriateness of Fam-FFC.
C: Inclusion Criteria

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)

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
D: Inclusion criteria:

* Diagnosis of cancer
* Age ≥ 18 yr

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)
