BC Guidelines are clinical practice guidelines and protocols that provide recommendations to B.C. practitioners on delivering high quality, appropriate care to patients with specific clinical conditions or diseases. These “Made in BC” clinical practice guidelines are developed by the Guidelines and Protocol Advisory Committee (GPAC), an advisory committee to the Medical Services Commission. The primary audience for BC Guidelines is BC physicians, nurse practitioners, and medical students. However, other audiences such as health educators, health authorities, allied health organizations, pharmacists, and nurses may also find them to be a useful resource.
There are several ways to find the guidelines you are looking for.
- Browse the guidelines alphabetically or by topic area.
- You can also download the entire collection of BC Guidelines (ZIP, 56.7MB) for future reference.

NEW: Obstructive Sleep Apnea: Assessment and Management in Adults
Obstructive Sleep Apnea: Assessment and Management in Adults (2021) guideline applies to adult patients 19 and older with suspected obstructive sleep apnea (OSA) and provides testing, referral and management recommendations. While sleep apnea may occur in 1-4% of children, pediatric diagnosis and management is beyond the scope of this guideline.
Key Recommendations include:
- If OSA is suspected, conduct a detailed history and a physical examination, focused on the upper airway.
- The STOP-Bang questionnaire can be used to help determine if a patient is at increased risk of moderate to severe OSA.
- While the most common symptom of OSA is excessive daytime sleepiness, the clinical presentation can vary. Completion of the Epworth Sleepiness Scale is recommended.
- Patients with untreated OSA may have increased perioperative morbidity. Consider appropriate screening when referring patients for potential surgery (e.g. STOP-Bang Questionnaire). See also the BC Surgical Rehabilitation Toolkit for further information. [Expert opinion]
- Testing and Referral
- Home Sleep Apnea Test (HSAT) should not be used to screen asymptomatic patients. HSAT is only recommended for the diagnosis of OSA in symptomatic patients who are determined to be at an increased risk of moderate-to-severe OSA, and who have no exclusion criteria (see Requisition).
- A negative or equivocal HSAT does not exclude OSA. If an HSAT is negative, inconclusive or technically inadequate, and OSA is suspected, polysomnography is recommended.
- BC now has a Standard Requisition for HSAT that referring practitioners are required to use.
- Symptomatic patients for which the HSAT is not the appropriate diagnostic test should be referred for a sleep disorder consultation for polysomnography. [Expert Opinion]
- Management and Follow-up
- When assessing whether a patient should be treated, it is important to consider the severity of the symptoms, presence and severity of any comorbid disease, presence of any safety-critical occupation and the results of all sleep studies.
- OSA is a serious chronic disease that warrants regular follow-up, short-term to ensure initial compliance and response to treatment and long-term to confirm continued effectiveness.
- Patients with OSA may be prone to drowsiness while driving. Physicians caring for these patients should be familiar with BC’s Driver Medical Fitness Information for Medical Professionals. [Expert Opinion]
- Surgery for OSA, including minimally invasive techniques to reduce tissue volume, incurs typical surgical risks. Since there may be effective medical alternatives to surgery, prior referral to a sleep disorder physician is recommended.
NEW: Fall Prevention - Risk Assessment and Management for Community-Dwelling Older Adults Guidelines
The scope of the Fall Prevention: Risk Assessment and Management for Community-Dwelling Older Adults guideline (2021) is to address the identification and management of older adults aged ≥ 65 years living in the community with risk factors for falls, and is intended for primary care practitioners. The guideline facilitates individualized assessment and provides a framework and tools to manage risk factors for falls and fall-related injuries. Hospital, facility-based care settings and acute fall management are outside the scope of this guideline, although some of the principles in this guideline may be useful in those settings.
Key recommendations include:
• Annually, or with a significant change in clinical status, ask patients ≥ 65 years about their fall risk using simple one-minute screening tools to identify people at risk of falls:
o Three question approach and/or
o Staying Independent checklist
• Recommend exercise to improve strength and balance and safe mobility. This is the most effective fall prevention intervention. See Exercise Prescription and Programs section.
• For those evaluated as “at risk” or who have had a fall, a multifactorial risk assessment is recommended over multiple visits to review (see Multifactorial Risk Assessment, Fall History and Intervention section):
o Medical conditions (including review of common geriatric conditions)
o Mobility (endurance, strength, balance and flexibility)
o An assessment of the home environment
o Osteoporosis risk assessment and management (increases risk of fracture from fall)
• After a fall, interdisciplinary assessment and care planning can reduce the risk of future falls. A team-based approach, when available, is recommended (see Referral Options section).
This two part guideline provides practical recommendations within the primary care setting for a graded, multimodal approach to supporting adult patients (≥ 19 years) with pain on a continuum from acute, subacute to chronic pain. Peer review is a critical component of guideline development. Please visit our External Review page to download the draft guideline and submit your feedback via our new online questionnaire.
Suspected Lung Cancer in Primary Care (2021) provides recommendations for primary care providers, for the investigation and management of adult patients (≥19 years of age) who present with signs or symptoms suggestive of lung cancer. Recommendations include the clinical assessment and appropriate referral of patients to a specialist. This guideline was developed in collaboration with the BC Cancer Primary Care Program (Family Practice Oncology Network) and was based on a guideline adaptation approach including a recent systematic search of the evidence.
Key Recommendations include:
- Tobacco remains the most significant cause of lung cancer.
- Smoking after a cancer diagnosis increases the risk of all-cause and cancer specific mortality, adverse effects on treatment outcomes, and increases the risk of recurrence or secondary cancers. Efforts should be focused on supporting patients to quit smoking and to reduce exposures to second-hand smoke.
- Although smoking represents the largest risk factor, there is increasing recognition of the rise in number of cases of lung cancer in people who have never smoked.
- When communicating with patients with lung cancer, health care providers should avoid bias based on assumptions about smoking history.
- Regardless of smoking history, patients with persistent, atypical, or otherwise unexplained cough or chest infection should be sent for a chest X-ray. If chest X-ray is negative but symptoms persist additional investigations including contrast enhanced CT scan of chest to include adrenals should be ordered.
- Long-term exposure to high concentrations of radon is a risk factor for lung cancer particularly in smokers. Radon is found in outdoor air in low concentrations. In indoor environments, radon levels can be much higher. Radon levels in B.C. are variable but may be higher in some communities east of the Coast Mountains.
- The following require an urgent referral to the emergency department: stridor, massive hemoptysis, new neurological signs suggestive of brain metastases or cord compression, superior vena cava syndrome/obstruction, or a large unilateral pleural effusion.
REVISED: Cataract – Treatment of Adults
The scope of the Cataract – Treatment of Adults guideline is to provide recommendations for primary care providers in the prevention, diagnosis, management and postoperative care of cataracts for adults (age 19 and older).
Key recommendations include:
- The following are recommended to delay the onset and progression of cataracts: smoking cessation, reduced ultraviolet (UV) -B exposure (hats, sunglasses with UV-B protection), and safety eyeglasses during high-risk activities at work or recreation to avoid eye trauma.
- Patients who are long-term users of corticosteroids (by any route) should be informed of the increased risk of cataract formation.
- Indications for cataract surgery are not limited to Snellen visual acuity alone and referral for cataract surgery consultation is indicated in the setting of glare, monocular diplopia or other non-visual functional impairment.
- Cataract surgery may be indicated in other ocular diseases for reasons independent of vision rehabilitation.
- When a cataract lens is surgically removed, it is replaced with a synthetic intraocular lens (IOL). There are many types of IOL’s available. IOL technologies and choices continuously evolve as does MSP coverage of IOLs. Patients can be reassured that MSP-covered monofocal lenses provide fully satisfactory visual correction in the vast majority of patients. Glasses are usually required after surgery for near and sometimes also distance vision. Non-MSP covered lenses may lessen dependency on glasses post-surgery, but may not be appropriate for all patients due to individual suitability or side effects. IOL selection evolves out of a comprehensive discussion with the surgeon.
- Primary care practitioners should be aware of postoperative “red flags”. Post-operative patients should be urgently assessed (within 24 hours) by their surgeon or an on-call ophthalmologist with increasing eye redness, pain or decrease in vision (see Table 4 for more details).
The scope of the Viral Hepatitis Testing (2021) guideline is to outline the use of laboratory tests to diagnose acute and chronic viral hepatitis in adults (≥ 19 years) in the primary care setting. Testing related to children or perinatally acquired viral hepatitis infection, or treatment information is outside the scope of this guideline.
Key recommendations include:
- There are very few acute HAV infections in BC. Cases relate to travel, contaminated food products or close contact with those who are infected.
- Self-limited disease not requiring ongoing serological follow-up. Post-vaccination testing is not recommended.
- Although there is currently no cure, treatment is available for chronic HBV infection. Patients with chronic HBV infection should be engaged into comprehensive specialist care. Consultation or referral is strongly recommended.
- In the absence of risk factors, routine HBV testing is not needed for those born in Canada.
- One-time HBV testing for immigrants from endemic areas is recommended.
- Vaccinate individuals susceptible to HBV infection when risk factors are present.
- Individuals being treated for HCV who are getting worked-up for HIV pre-exposure prophylaxis (PrEP), are immunosuppressed, or who are about to start immunosuppressive therapy, should be evaluated for prior HBV infection to assess the potential risk for reactivation of HBV.
- Curative treatments (> 95 % effective) are available for those who have HCV infection.
- Patients known to have HCV infection, but who have not been previously treated and cured, should be recalled and engaged into care for HCV treatment.
- One-time HCV testing for the birth cohort 1945-1965 can be considered.
- One-time HCV testing for immigrants from endemic areas is recommended.
- Annual HCV testing for susceptible individuals with ongoing risks for HCV infection or reinfection is indicated.
- Treatment providers must establish a respectful, trust-based relationship with all patients, and need to consider HCV treatment within a holistic wellness framework.
- Where appropriate, many individuals with HCV infection could benefit from further supports and enrolment into comprehensive care (e.g., opioid agonist therapy, mental health and addiction services, alcohol reduction).
- As of 2018, an estimated 28,607 people in BC living with hepatitis C infection (diagnosed and undiagnosed) remain untreated.
