THREAD: Medication adherence and shared decision-making

1/6 Our TI Letter 132 suggests a more democratic & ethical approach to shared decision-making: ti.ubc.ca/letter132

Here are 5⃣ highlights…

#MedEd #FOAMed #MedicationAdherence #PatientPreferences
2/6 Patients always retain right to say “no, thank you”🛑

Some pts may not want to accept their doctor's recommendations for a prescribed 💊 & have their own reasons to feel that it's not worth it for them.

This "intentional non-adherence" is a choice that should be respected
3/6 Studies have tested adherence aids

While these aids can improve adherence we don’t know if they lead to improved health outcomes 😕

See our TI Letter 132 on medication adherence: ti.ubc.ca/letter132 💻

#MedEd #FOAMed #MedicationAdherence #PatientPreferences
4/6 Discussing adherence with patients:

✅A chance to learn about patient preferences and treatment goals 🎯
✅Encouraging adherence without considering patient choice is NOT the goal👂🏼

#MedEd #FOAMed #MedicationAdherence #PatientPreferences
5/6. Pts might have difficulty adhering to recommendations due to issues such as:

✅Cost
✅Stigma
✅No access to a healthcare provider

Clinicians should help pts overcome barriers if possible: ti.ubc.ca/letter132

#MedEd #FOAMed #MedicationAdherence #PatientPreferences
6/6 Shared decision-making:

✅Do not assume your goals match pt's goals & preferences
✅Instead, engage the patient in a shared decision-making process such as SHARE

THREAD: Dr. John Mandrola: “The more you see, the harder the medicine gets”

1/7 Some new views on legacy prescriptions: Beta-blockers, ASA & #statins by Dr. John Mandrola

(based on @drjohnm presentation hosted by @drug_evidence Oct 17, 2020: bit.ly/32fsPiA)

#MedED
2/7 Example 1: Beta blockers in heart failure 💊♥️

Observational studies suggest beta-blockers for heart failure tx beyond 3 years are NOT associated with beneficial outcomes 😯

These findings challenge current recommendations: bit.ly/3acX9P7

#MedEd #deprescribing
3/7 Ex. 2: How about beta blockers to treat MIs, looking at research from pre-reperfusion & reperfusion eras?

Large meta-analysis of about 60 trials, with > than 100,000 pts found NO difference from using beta blockers in the reperfusion era: bit.ly/3dfvn6u

THREAD: Trama-DO or Trama-DON'T?
What to know about #tramadol

1/7 Tramadol has multiple mechanisms of action:
- via serotonin & norepinephrine reuptake inhibition
- after metabolism to M1 metabolite, via opioid agonism

bit.ly/3t5o7jC #chronicpain #arthritis #MedEd
2/7 People metabolize #tramadol variably 🤔💊

- Some who are ‘ultra rapid’ produce more M1 (opioid);
- Some ‘poor’ metabolizers (~20% with inactive CYP2D6) may have more SSRI/SNRI-like effect

Thus, analgesic & adverse effects are unpredictable
ncbi.nlm.nih.gov/books/NBK315950 #MedEd
3/7 Tramadol, once called a ‘safer’ opioid, causes tolerance and withdrawal, and is associated with addiction, overdose, and death

Observational studies show people treated with #tramadol, vs other opioids, are ↗️ likely to engage in prolonged opiate use #chronicpain #arthritis

THREAD: Tamiflu for #influenza prevention – the evidence

1/6 In 2019 21,000 BC citizens were prescribed Tamiflu (oseltamivir), many to prevent the flu. Flu prevention guidelines. AMMI Canada ammi.ca/?ID=171

Systematic review of Tamiflu safety: pubmed.ncbi.nlm.nih.gov/27246259/
2/6 Tamiflu for prevention ↘️ symptomatic flu (by 3%, NNT=33) with uncertain effect on asymptomatic flu.

One likely explanation is that Tamiflu has a central symptom lowering effect but may not ↘️ viral transmission.
pubmed.ncbi.nlm.nih.gov/27246259

#influenza #flu #tamiflu
3/6 Tamiflu doesn't reduce risk of developing flu-like illness though it can make people feel better (i.e. fewer self-reported symptoms) & reduces fever.

There is not enough evidence to say it prevents death, hospitalizations, or flu complications
