INTEGRATION ACTIVITY FORMAT

Students placed in groups of ~ 5-7
Each group chooses one of the studies below to review
Students then work in pairs and develop a one-slide critical appraisal and results synopsis
One to two students in each group will be chosen at random to present their findings to the class
A discussion about the appraisal and the appropriate clinical context for the results is had with the entire class for each study

MODULE

TRIAL PRESENTATION FORMAT

Studies chosen include landmark studies and/or studies that address important therapeutic issues for the particular module

Scenario 1 - Otitis Media - GROUPS 1, 7, 18, 19, 25, 36

Anthony Martin arrives at your pharmacy somewhat frustrated since his family physician declined to write an antibiotic prescription for his two and half year old son, Oscar. His symptoms started yesterday afternoon - Oscar complains of right ear pain but there is no discharge. Rectal temperature taken today was 38.5 degrees. His wife is sure Oscar has an ear infection since the last time he had these same symptoms, that was ultimately the diagnosis. Mr. Martin asks if you think buying acetaminophen is really “enough”?

Scenario 2 - Allergic Rhinitis - GROUPS 2, 8, 17, 20, 26, 35

Ruby Parmar is a firefighter. She is plagued by sinus congestion (preventing her from sleeping) and a runny nose associated with seasonal allergies. Her prescription for intranasal triamcinolone is typically effective, but she would like to know if a non-sedating anti-allergy pill would work just as well since it’s inconvenient carrying around the “nose spray”.

Intranasal steroids vs antihistamines for allergic rhinitis

Scenario 3 - Acute Sinusitis - GROUPS 3, 9, 16, 21, 27, 34

You are seeing a patient in clinic before her appointment with the primary care physician. She was feeling unwell with a “flu” last week. While most of her symptoms have resolved (cough, fever), the nasal congestion and discharge persists and so she has made an appointment (she is an otherwise healthy 32 year old with treated thyroid disease). She would like your advice for what treatment she should ask the doctor to prescribe.

Intranasal steroids for acute sinusitis

Scenario 4 - Glaucoma - GROUPS 4, 10, 15, 22, 28, 33

Mrs. Ada Waters is a 63 year-old woman you. Her ophthalmologist prescribed timolol and xalatan eye drops for treatment of open angle glaucoma. She has never really felt much different on treatment since she recovered from her first episode (of acute angle closure glaucoma requiring ER visit) and surgery. She asks you if the treatment is really making a difference.

Interventions for open angle glaucoma

Scenario 5 - Sore Throat - GROUPS 5, 11, 14, 23, 29, 32

You have a good friend who is applying for pharmacy. Her invitation for the multiple-mini interview (MMI) is coming up soon, but she is starting to experience a sore throat. While she is worried about not being able to speak through all of those stations, she knows she often gets a terrible headache along with her sore throat. She has an unused prescription for amoxicillin (unexpired) and wonders if you recommend for her to take it.

Antibiotics for sore throat

Scenario 6 - Conjunctivitis - GROUPS 6, 12, 13, 24, 30, 31

A man comes to your pharmacy (he appears in his early twenties) complaining of “pink eye”. He has had a pink discolouration and discharge from his left eye for two days. He asks if the OTC antibiotic eye drops (he’s holding a product with polymixin B) are any better than “waiting it out”.
