Acute respiratory tract infection (ARTI) is the most common reason for antibiotic prescription in adults. Antibiotics are often inappropriately prescribed for patients with ARTI. This article presents best practices for antibiotic use in healthy adults (those without chronic lung disease or immunocompromising conditions) presenting with ARTI.
A narrative literature review of evidence about appropriate antibiotic use for ARTI in adults was conducted. The most recent clinical guidelines from professional societies were complemented by meta-analyses, systematic reviews, and randomized clinical trials. To identify evidence-based articles, the Cochrane Library, PubMed, MEDLINE, and EMBASE were searched through September 2015 using the following Medical Subject Headings terms: “acute bronchitis,” “respiratory tract infection,” “pharyngitis,” “rhinosinusitis,” and “the common cold.”
Clinicians should not perform testing or initiate antibiotic therapy in patients with bronchitis unless pneumonia is suspected.
Clinicians should test patients with symptoms suggestive of group A streptococcal pharyngitis (for example, persistent fevers, anterior cervical adenitis, and tonsillopharyngeal exudates or other appropriate combination of symptoms) by rapid antigen detection test and/or culture for group A Streptococcus. Clinicians should treat patients with antibiotics only if they have confirmed streptococcal pharyngitis.
Clinicians should reserve antibiotic treatment for acute rhinosinusitis for patients with persistent symptoms for more than 10 days, onset of severe symptoms or signs of high fever (>39 °C) and purulent nasal discharge or facial pain lasting for at least 3 consecutive days, or onset of worsening symptoms following a typical viral illness that lasted 5 days that was initially improving (double sickening).
Clinicians should not prescribe antibiotics for patients with the common cold.

Appropriate Antibiotic Use for Acute Respiratory Tract Infection in Adults: different advices for pharyngitis.
Dear editor,The advice that ‘clinicians should test patients with symptoms suggestive of group A streptococcal (GAS) pharyngitis by rapid antigen detection test (RAT) and/or culture for group A Streptococcus’ (1) is not in agreement with different European guidelines. (2)The problem with GAS is that there is no sufficient reliability of clinical findings and tests, even in combination. According to the guidelines from the UK National Institute for Health and Care Excellence and the Scottish Intercollegiate Guidelines Network (NICE/SIGN) (3), neither RAT nor throat swab culture can differentiate between the streptococcal carrier state and invasive infection.Reflexive culture with throat swab has a poor sensitivity (73%–80%); results take up to 48 hours to be reported which is too late to significantly influence the clinical course (3); there is an asymptomatic carriage range from 6% to 40%: Streptococcus can live in our noses, mouths, and throats and not make us sick, which means that having a positive RAT or culture does not necessarily mean there is an infection. Swabs may be useful in high-risk groups, to guide the choice of treatment if treatment failure occurs. (3)Increasingly more and European guidelines consider acute sore throat a self-limiting disease (2). Antibiotics are prescribed immediately only when the patient has risk factors, decreased immunocompetence, or extreme illness (approximately 5% of cases). (2)Antibiotics should not be used to secure symptomatic relief in sore throat. (3) One or 2 days of extra acetaminophen/paracetamol (or nonsteroidal anti-inflammatory drugs) every 4 hours can replace unnecessary antibiotic use in most cases and might reduce the problem of antibiotic resistance.When the patient does not improve within 2 or 3 days, the physical examination must be repeated to exclude peritonsillar abscess and even the Lemierre syndrome.(4)The conclusion is that in patients with respiratory infections where clinicians feel it is safe not to prescribe antibiotics immediately, no antibiotics with advice to return if symptoms do not resolve is likely to result in the least antibiotic use, while maintaining similar patient satisfaction. (5)We applaud that the guideline does not recommend tonsillectomy solely to reduce the frequency of group A streptococcal pharyngitis in adults. (1)1.

Guidelines on appropriate antibiotic use for acute respiratory tract infections
The four high-value care recommendations described in the recently published guidelines on appropriate antibiotic use for acute respiratory tract infections (RTI) in adults are very clear, thereby assisting clinicians in providing the best care for patients as well as reducing variations and arbitrariness in practice (1). Notwithstanding, clinical guidelines are particularly challenging to apply to some groups in which the evidence is not sufficiently solid, such as in very severe infections and elderly patients with multiple comorbidities. Clinical trials comparing antibiotic and placebo very often do not include this kind of patients, the so-called ‘special’ cases. The key question is how applicable clinical guidelines are to these patients. In addition, a fear of complications as well as complacency and the existence of different guidelines across countries, i.e. acute pharyngitis, may explain the greater prescription of antibiotics for processes for which they are not indicated (2). This is why clinical practice guidelines have been criticized as being disease-driven rather than patient-driven (3). The new Spanish guidelines on RTIs in primary care clearly state that antibiotics are never required for the common cold and influenza. However, there are some situations of otitis media, rhinosinusitis, pharyngitis, acute bronchitis and exacerbations of chronic obstructive pulmonary disease for which antibiotics are warranted. Moreover, in an attempt to consider this grey area these guidelines also define categories of patients for whom clinicians might consider prescribing an antibiotic, recommending in these cases, for instance, delayed prescribing of antibiotics, which has recently been shown to be an effective way of reducing antibiotic consumption in Spain (4).With the aim of evaluating the percentage of cases for which antibiotics may be prescribed, we carried out an audit-based study from January to March 2015, in which a total of 248 general practitioners throughout Spain registered all cases with RTIs over a 3-week period, including a total of 11,137 patients. The overall antibiotic prescribing rate was 27.2% whereas they should have only been definitely prescribed in 7.5% of the cases and might have been prescribed in another 6.4% according to these guidelines. Doctors know that unnecessary antibiotics expose patients to adverse drug reactions and increase the prevalence of antibiotic-resistant bacteria but uncertainty in some cases makes the therapeutic decision of antibiotic prescription difficult in practice and guidelines should also endorse these situations. However, even with the use of conservative guidelines, current antibiotic prescription clearly surpasses the recommended rate.References1.

We appreciate Dr. Matthys’s comments (1) and acknowledge that even when patients with pharyngitis meet recommended criteria for group A streptococcal (GAS) testing, as many as 20% of children and fewer adults will have a positive result from colonization rather than true disease (2). This leads to overuse of antibiotics for pharyngitis.
In a recent study examining outpatient antibiotic prescribing, pharyngitis was one of the conditions for which antibiotics were most commonly prescribed; 56% and 72% of pediatric and adult pharyngitis cases, respectively, resulted in an antibiotic prescription far exceeding estimates of the true prevalence of GAS infection and colonization (37% for children and 18% for adults) (3). This suggests that in many cases providers are either not testing for GAS or are prescribing antibiotics despite a negative test result. The 2012 Infectious Diseases Society of America (IDSA) clinical guideline for diagnosis and management of GAS pharyngitis recommends testing for GAS in patients with clinical symptoms suggestive of GAS pharyngitis and prescribing antibiotics for patients with a positive GAS test result (4). An important first step in reducing unnecessary antibiotic use in the United States would be to follow the IDSA recommendation to only treat patients with positive GAS test results. We agree with Dr. Matthys that providers should offer recommendations for symptomatic relief. The Centers for Disease Control and Prevention has developed a symptomatic prescription pad that providers can use to guide symptom management in their patients (http://www.cdc.gov/getsmart/community/materials-references/print-materials/hcp/viral-rx-pad-color.pdf).
While acute pharyngitis in adults is usually self-limited, antibiotic treatment in patients with confirmed GAS pharyngitis has been shown to provide modest benefit (4,5). The goals of treatment in patients with GAS pharyngitis are to prevent nonsuppurative complications, reduce the duration of symptoms, and reduce transmission of GAS to close contacts (4,5). The magnitude of the benefit depends on the epidemiology of GAS infections in the region and the risk of post-streptococcal complications. In light of the growing threat of antibiotic resistance and increasing recognition of adverse events associated with antibiotic use, including community-associated Clostridium difficile infection, studies that carefully weigh the benefits and risks of antibiotic treatment for GAS pharyngitis are needed.
