Bacterial infections of the respiratory tract, when they do occur, are generally a secondary problem caused by complications from viral infections such as influenza. While it is often difficult to distinguish bacterial from viral sinusitis, nearly all cases are viral. Though cases of bacterial sinusitis can benefit from antibiotics, evidence of such cases does not typically surface until after at least seven days of illness. Not only are antibiotics rarely indicated for upper respiratory illnesses, but some patients experience adverse effects from such medications.

There is little evidence that detection of coronary artery stenosis in asymptomatic patients at low risk for coronary heart disease improves health outcomes. False positive tests are likely to lead to harm through unnecessary invasive procedures, over-treatment and misdiagnosis. Chest X-rays for asymptomatic patients with no specific indications for the imaging have a trivial diagnostic yield, but a significant number of false positive reports. Potential harms of such routine screening exceed the potential benefit.

The potential harm from screening women younger than 21 years of age outweighs the benefits and there is little evidence to suggest the necessity of conducting this test annually when previous test results were normal. Women who have had a full hysterectomy for benign disorders no longer require this screening. Screening should stop at age 70 if three previous test results were normal.

There is little evidence to indicate there is value in routine blood tests in asymptomatic patients; instead, this practice is more likely to produce false positive results that may lead to additional unnecessary testing. The decision to perform screening tests, and the selection of which tests to perform, should be done with careful consideration of the patient’s age, sex and any possible risk factors.

Because Canada is located above the 35° North latitude, the average Canadian’s exposure to sunlight is insufficient to maintain adequate Vitamin D levels, especially during the winter. Therefore, measuring serum 25-hydroxyvitamin D levels is not necessary because routine supplementation with Vitamin D is appropriate for the general population. An exception is made for measuring Vitamin D levels in patients with significant renal or metabolic disease.

If, after this careful assessment and discussion, a woman’s breast cancer risk is not high, current evidence indicates that the benefit of screening mammography is small. Furthermore, for this age group there is a greater risk of false-positive screening results and consequently of undergoing unnecessary or harmful follow-up procedures. As always, clinicians need to be aware of changes in the balance of evidence on risk and benefit and support women in understanding this evidence. High quality materials to assist these discussions are available through the Canadian Task Force on Preventive Health Care.

A periodic physical examination has tremendous benefits; it allows physicians to check on their healthy patients while they remain healthy. However, the benefits of this check-up being done on an annual basis are questionable since many chronic illnesses that benefit from early detection take longer than a year to develop. Preventive health checks should instead be done at time intervals recommended by guidelines, such as those noted by the Canadian Task Force on the Periodic Health Examination.

While self-monitoring of blood glucose (SMBG) for patients with diabetes is recommended by certain groups to help monitor glycemic control, for most adults with type II diabetes who are not using insulin, many studies have shown that routine SMBG does little to control blood sugar over time.

The primary rationale for screening asymptomatic patients is that the resulting treatment results in improved health outcomes when compared with patients who are not screened. There is insufficient evidence available indicating that screening for thyroid diseases will have these results.

The immediate postoperative period or acute episodes of pain typically refers to a time period of three days or less, and rarely more than seven days. Prescribe the lowest effective dose and number of doses required to address the expected pain. This recommendation does not apply to individuals already on long term or chronic opioids or opioid agonist treatment.

Depending on the pain mechanism and patient co-morbidities, this can include acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclics and gabapentinoids. Other non-medication modalities for managing acute, subacute and chronic pain may include exercise, weight loss, cognitive-behavioural therapy, massage therapy, physical therapy and/or spinal manipulation therapy. An opioid trial should be guided by clear criteria for monitoring the success of an opioid trial and a plan for stopping opioids if criteria are not met.
