For many, upper respiratory tract infections register as a small blip on the radar, serving as a nuisance that is counted down on a 7- to 14-day recovery clock.
Sniffle! Cough! Sneeze! Come fall and winter, these harmonious sounds amplify in clinic waiting rooms, schools, and work facilities. For many, upper respiratory tract infections (URTIs) register as a small blip on the radar, serving as a nuisance that is counted down on a 7- to 14-day recovery clock. To others, it can be a scary time of balancing a chronic illness, such as a teetering asthmatic. Regardless of how, URTIs directly or indirectly touch all lives with an average incidence of 5 to 7 episodes in younger children and 2 to 3 episodes in adults annually. As the seasonal revolving door begins turning, so do health care providers in their challenges to serve as stewards of appropriate antibiotic usage.
More than 200 viruses have been identified as attributing factors to URTIs.1Rarely do infections of the upper respiratory tract require or escalate to the point of requiring an antibiotic. Yet, the tug-o-war between patient requests and provider guideline adherence is an everyday reality in health care.
"Antibiotic stewardship" is not a catchy term or a health care fad. It's a necessity for long-term survival to preserve antimicrobials and prevent downstream resistance. With utilization of an antibiotic, the opportunity for the evolution of a “super bug” emerging with superior alterations to combat future efficacy develops. This not only occurs at an individual level but also impacts the resistance of potential infections to the entire community. Appropriate antibiotic prescription is a quality-of-care issue. Antibiotic stewardship optimizes the use of antibiotics through strategic selection of who, what, when, where, and how the medication is received.
Approximately half of prescribed antibiotics are inappropriate.1Ranking high atop the list of antibiotic misuse are patients seeking care for viral acute URTIs.2Most clinicians spout off guidelines with ease but fail to follow those guidelines. Why? The tug-o-war is real. Patient pressure and quality ratings derived from customer satisfaction name a few arguments for the flawed execution. Clinicians are in the business to “do no harm.” There is no doubt that dethroning a patient’s beloved Zpak could sway pa- tient-clinician trust. When perception is reality, counseling around antibiotic fallacy may be seen as a threat to the patient that his or her need will not be satisfied. However, the real harm is prescribing an unneeded antibiotic.
The ability to read emotional queues, determine root of beliefs, and empathetically translate an understanding—all while providing a “why”—takes finesse and practice. Clinicians trained in communication strategies have shown nearly a 15% downward shift in antibiotic prescribing.3In determining that an antibiotic is not needed, most patients are satisfied with recommendations or a prescription for alternate symptom relief alone. Others may require a deeper explanation reviewing virus versus bacteria in a bite-sized, digestible format that is palatable and can be consumed in 3 minutes or less. Delayed antibiotic prescriptions—a practice in which a prescription is provided to be filled if symptoms persist or worsen after an outlined period of time—has shown to decrease antibiotic use while still providing a safety net to the patient. Technique should be tailored on a patient-by-patient basis.
Appropriate Antibiotic Use
Delayed use and prevention of misuse is etched in the brains of clinicians and rising in awareness in the patient population. On the flip side to the antibiotic stewardship double-edged sword, it may be just as important to take antibiotics if the infection is caused by bacteria. The following includes a brief review of URTIs and indications for antibiotics.
Acute Bacterial Rhinosinusitis
Persistent nasal drainage lasting more than 10 days, worsening course after initial improvement, or severe onset with fever of 102 degrees or higher with nasal discharge for 3 or more days are indications that bacteria may be present in a young child with acute rhinosinusitis. Older children and adults may also experience localized pain and tenderness specific to the affected sinus. Streptococcus pneumonia followed by Haemophilius influenza are the leading pathogens in incidences of acute bacterial rhinosinusitis.4Where sole symptomatic treatment is not appropriate, amoxicillin-clavulanate is the recommended initial therapy for patients without risk factors for antibiotic resistance. In patients who are allergic to penicillin, doxycycline or clindamycin are alternative options. For patients with risk factors for antibiotic resistance, high-dose amoxicillin-clavulanate should be used.
Acute Otitis Media
While watchful waiting is the preferred treatment for acute otitis media (AOM) in children 2 years or older, antibiotics are indicated when: otalgia is present for longer than 48 hours, temperature exceeds 102.2 within the past 48 hours, bilateral tympanic membranes are affected, otorrhea is present, access for follow-up may be limited, or immunocompetency is of concern.5AOM in adults may be treated with antibiotics rather than watchful waiting. The preferred drug for treatment is amoxicillin or a macrolide in instances of patients allergic to penicillin. Cephalosporins may be used as an alternate for chil- dren allergic to penicillin, depending on reaction type.6
Epiglottitis is a potentially life-threatening illness with sudden onset. Symptoms include sore throat, drooling, muffled voice, dyspnea, fever, and fatigue. Haemophilus influenza type B (Hib) is the most common pathogen attributed to epiglottitis in children. In adults with epiglottitis, causes vary and often no identified pathogen is detectable. When a pathogen is detectable, Hib remains the most common offender in adults though identified in lower incidence.7Antibiotics covering suspect organisms should be initiated immediately and may be adjusted as indicated following culture results. Airway preservation is key in the treatment of epiglottitis through glucocorticoids, oxygen, and artificial airway dictated by severity.6
Patients with Group A streptococcal (GAS) pharyngitis commonly present with exudative tonsils, temperature of 100.9 or higher, and enlarged (>1cm) tender anterior cervical nodes in the absence of coryza. Throat culture should be used to confirm a negative rapid strep test in children, as well as adults carrying high suspicion of GAS despite negative rapid result.8A 10-day regimen of penicillin V remains the preferred agent for treatment of GAS, though amoxicillin is often used more widely because it is more favorable to patient taste.9
Whooping cough is a highly contagious URTI that is characterized by inspiratory whoop in 30% of cases, violent coughing bursts, or post-tussive emesis. Bordetella pertussis is the offending pathogen in whooping cough. Although most individuals will improve over a month and a half, early intervention with antibiotics can help to decrease the duration, severity, and transmission to others. The CDC recommends using azithromycin or clarithromycin as preferred macrolides for treatment. Trimethoprim-sulfamethoxazole serves as the alternate option in patients unable to tolerate the macrolide of choice.10
Prevention of URTIs
Last, but undoubtedly the most important aspect in the treatment of URTIs, is primary prevention. Regular washing of hands, covering one’s mouth when coughing or sneezing, and keeping hands away from the eyes, nose, and mouth are simple actions that prevent the spread of URTIs from person to person. Consistent disinfection, particularly in high risk areas or places with increased foot traffic, is also valuable to keeping a cough-free community. Routine moderate exercise and engagement in stress-relieving activities contribute to boosting immunity.
The annual flu vaccine is the best way to prevent the spread of influenza throughout the community and should be strongly considered in individuals without contraindications. Flu-related deaths continue to strike each year. Although incidence and peak position vary each year, one thing is certain—the flu will always rear its ugly head. Assist in abolishing myths and protecting against this URTI through education and routine seasonal offering of the influenza immunization.
Fatigue, cough, congestion, along with any other variation of the URTI symptom continuum lead to decreased productivity and loss of days at school and work—sparing no age or schedule. Regardless of how, URTIs directly or indirectly touch all lives. Education and communication are just as important as the treatment and medication recommendations. Health care providers are called to meet the challenges that antibiotic stewardship poses in a balancing act that supports trust in the patient—provider relationship, expectation, and appropriate use to promote the highest quality of care for patients and the community.
