Empowering Primary Care Through Evidence

PEER is a primary care led research team focused on providing useful and relevant evidence to primary care providers.

Opioid Use Disorder (OUD) Summary is Live!

The PEER group has created a new video that summarizes key points of the new opioid use disorder guideline for primary care.

Most Recent Tools for Practice

Tools for Practice #247 – Fact or Fad: Intermittent fasting for sustained weight loss

Does intermittent fasting result in greater sustained (>6 month) weight loss than continuous dieting in adults?

Bottom Line: Although inconsistently defined, intermittent fasting (example 500 kcal/day for 2 days/week) and continuous dieting (~25% reduction in caloric intake daily) result in similar weight loss, usually ~5-9kg at 6 months-1 year. Discontinuation rates with both diets is up to ~60%. Read More

Tools for Practice #246 – Just wait a minute: Point-of-care testing for Group A Streptococcal pharyngitis

In patients with sore throat, how accurate are point-of-care tests in the diagnosis of Group A beta-hemolytic streptococcal (GABHS) pharyngitis?

Bottom Line: Point-of-care testing, including rapid antigen detection tests and newer nucleic acid detection tests for GABHS pharyngitis are useful for ruling in a diagnosis of GABHS when positive (specificity 95%-99%). Nucleic acid detection tests may be more sensitive than rapid antigen detection tests (92% versus 85%). While immediate testing and treatment may not always be required, populations at increased risk of GABHS complications, such as Canada’s Indigenous populations, are more likely to benefit. Read More

Tools for Practice #245 – Taking a hard look at the evidence: Phosphodiesterase-5-inhibitors in erectile dysfunction

What is the efficacy and safety of phosphodiesterase-5-inhibitors (PDE5 inhibitors) for erectile dysfunction?

Bottom Line: PDE5 inhibitors increase the proportion of successful sexual intercourse attempts to ~65% versus ~30% for placebo. For every 3 men given a PDE5 inhibitor compared to placebo, an additional 1 will have “improved erections”. Read More

Tools for Practice #244 – Injecting Evidence into Platelet-Rich Plasma Injections

How effective is platelet-rich plasma for treating Achilles tendinopathy, lateral epicondylitis, and rotator cuff tendinopathy?

Bottom Line: The best quality evidence shows no difference in pain, function, or return to sport between platelet-rich plasma, dry needling, or saline for patients with Achilles tendinopathy, lateral epicondylitis, or rotator cuff tendinopathy. Read More

Tools for Practice #243 – Spread the Word: Widespread Distribution of Naloxone to Decrease Opioid-Related Deaths

Does population-based or programmatic provision of naloxone kits decrease the risk of opioid-related deaths in people who use opioids?

Bottom Line: Offering naloxone kits and overdose related education for people who use opioids and their community may decrease opioid related deaths by ~7 per 100,000 population over one year. Effectiveness is likely influenced by magnitude of opioid problem in a given community and other confounders (like co-ingestions, co-morbidities, type and dose of opioid used). Read More

PEER Values

When creating primary care education and programs, the PEER team focuses on minimizing bias, patient orientated outcomes, shared decision making, collaboration and most importantly simplicity.

Who is PEER?

Patients, Experience, Evidence and Research (PEER) was formed between a group of primary care providers who shared a common belief that evidence should be made accessible to all primary care providers.
