Head injuries in children and adults are common presentations to the emergency department. Minor head injury is characterized by: Glasgow Coma Scale (GCS) 13-15, associated with either witnessed loss of consciousness, definite amnesia, or witnessed disorientation. Most adults and children with minor head injuries do not suffer from serious brain injuries that require hospitalization or surgery. CT head scans performed on patients without signs of significant injuries can expose patients to unnecessary ionizing radiation that has the potential to increase patients’ lifetime risk of cancer. They also increase length of stay and misdiagnosis. There is strong evidence that physicians should not order CT head scans for patients with minor head injury unless validated clinical decision rules suggest otherwise (i.e., Canadian CT head rule for adults, and CATCH or PECARN rules for children). Despite their validity, these rules are never 100% sensitive and are meant to assist and not replace, clinical judgement.

Share on Facebook Share on TwitterRespiratory distress from bronchospasm/wheezing is a common presentation in both children (i.e., bronchiolitis) and adults (i.e., bronchitis/asthma) seen in the emergency department. Most patients with symptoms do not have bacterial infections that require antibiotic treatment or influence outcomes (i.e., hospitalization). Inappropriate administration of antibiotics can expose patients to unnecessary risks (i.e., allergies, rash, diarrhea and other side-effects) and has the potential to increase patients’ risk of antibiotic induced diarrhea, including infections with C. Difficile. These prescriptions also increase overall antibiotic resistance in the community, and limit the effectiveness of standard antibiotics in the treatment of legitimate bacterial infections. There is strong applied research evidence to recommend that physicians should not prescribe antibiotics in children (i.e., bronchiolitis) and adults (i.e., bronchitis and asthma) with wheezing presentations.

Share on Facebook Share on TwitterAdults with non-specific lumbosacral (low back) pain, in the absence of significant trauma (i.e., car crash, acute axial loading, acute hyperflexion, etc.), commonly present to the emergency department. The evaluation of patients presenting with non-traumatic low back pain should include a complete focused history and physical examination to identify “red flags” that may indicate significant pathology. These may include, but are not limited to: features of cauda equina syndrome, weight loss, history of cancer, fever, night sweats, chronic use of systemic corticosteroids, chronic use of illicit intravenous drugs, patients with first episode of low back pain over 50 years of age and especially if over 65, abnormal reflexes, loss of motor strength or loss of sensation in the legs. In the absence of red flags, physicians should not order radiological images for patients presenting with non-specific low back pain. Imaging of the lower spine for symptomatic low back pain does not improve outcomes, exposes the patient to unnecessary ionizing radiation and contributes to flow delays without providing additional value.

Share on Facebook Share on TwitterNeck pain resulting from trauma (such as a fall or car crash) is a common reason for people to present to the emergency department. Very few patients have a cervical spinal injury that can be detected on radiographs (“X-rays”). History, physical examination and the application of clinical decision rules (i.e., the Canadian C-spine rule) can identify alert and stable trauma patients who do not have cervical spinal injuries and therefore do not need radiography. The Canadian C-spine rule has been validated and implemented successfully in Canadian centres, and physicians should not order imaging unless this rule suggests otherwise. Unnecessary radiography delays care, may cause increased pain and adverse outcomes (from prolonged spinal board immobilization), and exposes the patient to ionizing radiation without any possible benefit. This strategy will reduce the proportion of alert patients who require imaging.

Share on Facebook Share on TwitterAbscesses are walled off collections of pus in soft tissue, with Staphylococcus aureus (both sensitive and resistant to methicillin) being the microbe most frequently involved. Most uncomplicated abscesses should undergo incision in the emergency department using local analgesia or procedural sedation, complete drainage and appropriate follow-up. Evidence suggests that antibiotics are not routinely required after abscess incision and drainage of an uncomplicated abscess. Physicians should not prescribe antibiotics for these patients, unless the patients are immunocompromised, systemically ill, or exhibit extensive surrounding cellulitis or lymphangitis.

Share on Facebook Share on TwitterPatients commonly present to the emergency department with syncope. Syncope is a transient loss of consciousness followed by a spontaneous return to baseline neurologic function that does not require resuscitation. The evaluation of syncope should include a thorough history and physical exam to identify high-risk clinical predictors for CT head abnormalities. These high-risk predictors include, but are not limited to: trauma above the clavicles, headache, persistent neurologic deficit, age over 65, patients taking anticoagulants, or known malignancies. Many patients with syncope receive a CT scan of the head; however, in the absence of these predictors, a CT head is unlikely to aid in the management of syncope patients. CT scans can expose patients to unnecessary ionizing radiation that has the potential to increase patients’ lifetime risk of cancer. Unwarranted imaging also increases length of stay and misdiagnosis.

Share on Facebook Share on TwitterMany adults present to the emergency department with chest pain and/or shortness of breath. The majority of adult patients with these symptoms do not have a pulmonary embolism (PE) that requires investigation with a CT pulmonary angiogram (CTPA) or ventilation perfusion (VQ) lung scan. CTPAs or VQ scans expose patients to ionizing radiation that has the potential to increase patients’ lifetime risk of cancer. CTPAs also place patients at risk for potential allergic reaction and acute kidney injury from the intravenous contrast required for the CTs. Imaging also increases length of stay and may contribute to misdiagnosis. Evidence demonstrate that physicians should not order CTPAs or VQ scans to diagnose PE until risk stratification with a clinical decision rule (Wells score, PERC rule) has been applied and d-dimer biomarker results are obtained for those patients where it is indicated. For high-risk populations in which the clinical decision rules have not been validated (i.e., pregnancy, hypercoagulability disorders), physicians are urged to exert their clinical judgment.

Share on Facebook Share on TwitterAdults and children frequently present to the emergency department with sore throats (pharyngitis). The vast majority of cases of pharyngitis are caused by self-limiting viral infections that do not respond to antibiotics. The benefit of antibiotics for the approximately 10% of cases in adults (25% in children), caused by bacteria (principally Group A Streptococcus (GAS)) is modest at best, although is associated with fewer complications and a slightly shorter course of illness. Inappropriate administration of antibiotics can expose patients to unnecessary risks (i.e., allergies, rash and diarrhea), and increase overall antibiotic resistance in the community. Evidence suggests that antibiotics should only be used in patients with intermediate and high clinical prediction scores for GAS (CENTOR or FeverPAIN score) AND confirmatory testing (throat cultures or rapid testing) that are positive for GAS, especially in children.

Share on Facebook Share on TwitterFoot and ankle injuries in children and adults are very common presentations to emergency departments. The Ottawa Ankle Rules (OAR) have been validated in both children (greater than 2 years old) and adult populations, and have been shown to reduce the number of X-rays performed without adversely affecting patient care. In alert, cooperative and sensate patients with blunt ankle and/or foot trauma within the previous ten days and who are not distracted by other injuries, only those who fulfill the OAR should undergo ankle and/or foot X-rays. Imaging of the ankle and/or foot in patients who are negative for the OAR does not improve outcomes, exposes the patient to unnecessary ionizing radiation and contributes to flow delays without providing additional value.

Share on Facebook Share on TwitterBoth adults and children commonly present to the emergency department with symptoms of a middle ear infection, or acute otitis media (AOM). The symptoms of AOM include fever, earache, discharge from ear, and/or decreased hearing. Evidence suggests that adults and children with uncomplicated AOM do not need antibiotics. Treatment should focus on analgesia and the use of antibiotics should be limited to complicated or severe cases. A watch and wait approach (analgesia and observation for 48 to 72 hours) should be considered for healthy, non-toxic appearing children older than six months of age with no craniofacial abnormalities, mild disease (mild otalgia, temperature < 39°C without antipyretics), and who have reliable medical follow-up. Antibiotics should be considered if the child’s illness does not improve during the observation period, and for those children who are < 24 months of age with infection in both ears, and in those with AOM and ear discharge. Similarly, antibiotics should not be used for the initial treatment of uncomplicated AOM in adults. Delayed antibiotics are an effective alternative to immediate antibiotics to reduce antibiotic use. Inappropriate administration of antibiotics can expose patients to unnecessary risks (i.e., allergies, rash and diarrhea), and increase overall antibiotic resistance in the community.
