THREAD: How best to treat Urinary Tract Infections?

1/6 Our new TI Therapeutics Letter 135 describes the best approach for treating symptomatic, uncomplicated lower urinary tract infections (UTIs)

👉🏽ti.ubc.ca/letter135

#MedEd #FOAMed #UTIs #BetterPrescribing

2/6 Use symptoms, not tests to diagnose UTIs:

Uncomplicated lower UTI can be diagnosed with > 90% probability if pt has 2 or more of dysuria, urgency, and frequency, and no vaginal discharge.

This is less reliably predicted for older women.

👉🏽ti.ubc.ca/letter135

#MedEd

3/6 No need to culture:

✅Fewer than 2% of urine cultures meaningfully impact choice of treatment or need for follow-up
✅Most guidelines recommend against culture for
symptomatic uncomplicated #UTIs

THREAD: Bring it down safely! ↘️💊

1/6 6⃣tweets about our new TI Therapeutics Letter 134: Finding the lowest effective dose for non-opioid #analgesics

👉🏾 Full Letter: ti.ubc.ca/letter134

#MedEd #medsafety #prescribing #BetterPrescribing

2/6 Consistent evidence that minority of pts get clinically meaningful pain relief from any dose of:
✅#Cyclobenzaprine (at best 1/4)
✅#Duloxetine (at best 1/6)
✅#Gabapentin / #Pregabalin (at best 1/6)

👉🏾ti.ubc.ca/letter134

#MedEd #ptsafety #BetterPrescribing #prescribing

3/6 Gabapentin, pregabalin, duloxetine:

A 2021 Canadian systematic review found NNT (numbers needed to treat) of 6-7 for "clinically meaningful benefit" (defined as ≥30% reduction in pain or pain & function)

THREAD: Primary #hypertension therapy: after thiazides, an ACEI or an ARB?

1/8 Nearly 650,000 British Columbians took an ACEI or ARB in 2021

Our new TI Therapeutics Letter reiterates evidence for one of the most common primary care tx choices: ti.ubc.ca/letter133

#MedEd

2/8 Lower #BloodPressure not the Main Goal

#Antihypertensives lower various measures of blood pressure (BP) 💊

But... not all BP lowering drugs are proven to reduce both morbidity & mortality

👉🏾ti.ubc.ca/letter133

#MedEd #prescribing #hypertension

3/8 The importance of clinical outcomes

Basing decisions on which drug lowers #BloodPressure the best cannot guarantee the best clinical outcomes

THREAD: Evidence for oseltamivir for #influenza prevention

1/6 Not much #flu last year, yet almost 14,000 BC residents were prescribed #oseltamivir (Tamiflu) for prevention

✅Flu guidelines bit.ly/3wwGJei

✅Systematic review of Tamiflu safety pubmed.ncbi.nlm.nih.gov/27246259

2/6 #Oseltamivir for prevention reduces ↘️ symptomatic influenza by 3%, (NNT=33) with an uncertain effect on asymptomatic #influenza

It likely has a central symptom reducing effect but may not reduce viral transmission
pubmed.ncbi.nlm.nih.gov/27246259

#Tamiflu #prescribing

3/6 #Oseltamivir won’t reduce the risk of developing influenza-like illness though it can make people feel better (i.e. fewer symptoms) and reduces ↘️ fever

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