MAID eligibility criteria
1. Be eligible for health services funded by government (i.e. have a health card) 2. Be ≥ 18 years old and mentally competent 3. Have a grievous and irremediable* medical condition 4. Make a voluntary request for MAID, free from outside pressure or influence 5. Provide informed consent • Must be at a point where a natural death is REASONABLY FORESEEABLE, but does not have any requirements on a specific prognosis
30
MAID process steps
1. A dated, written request is made before 2 independent witnesses 2. Two MD/NPs will assess eligibility for MAID (see last slide) 3. Must wait 10 full days, from date patient signed written request, before MAID can be provided, Or <10 days if death is imminent or pt will lose capacity. Must again give consent right before drugs given.

After how many cycles of Bleomycin is Bleomycin Pneumonitis commonly seen?
Rare complication of (1-3%), but is seen in up to 15% of patients on CT. Dose-dependent and typically seen following the 3rd/4th cycle of chemotherapy. STOP BLEO.
33
Methylnaltrexone (Relistor©) is used for refractory nausea. What is the MOA and what are common and serious side effects?
- mu-opioid receptor antagonist which has restricted ability to cross the blood brain barrier due to its quaternary amine structure. - Rare but serious side effects include: Gastrointestinal perforation (more common in patients with conditions affecting the integrity of the gastrointestinal tract), Severe and persistent diarrhea, Opioid withdrawal
