One of the most common diagnoses in the United States, allergic rhinitis is often misdiagnosed and/or undertreated.
One of the most common diagnoses in the United States, allergic rhinitis is often misdiagnosed and/or undertreated.
Allergic rhinitis (AR) is one of the most common diagnoses in the United States, affecting an estimated 10% to 30% of adults and up to 40% of children.1Research estimates that AR is the reason for 13 million medical office visits annually,2many of which are to retail clinics. Each year, 25% of US households have at least 1 member with AR symptoms.3It is common for patients to have tried multiple OTC allergy medicines before they seek professional medical care for their AR symptoms. The financial and societal burdens of AR are significant and have been referred to by some as “massive.”4Studies show AR also has a negative impact on a patient’s quality of life, affecting emotional function, activities, sleep, and comorbid conditions.5
In 2006, a landmark study, “Allergies in America,” surveyed 2500 adults who had been diagnosed with either AR or nonallergic rhinitis and who had taken prescription allergy medication in the previous 12 months. The survey results demonstrated the most commonly reported symptom was nasal congestion. Nearly 40% of patients said that their related discomfort was intolerable without some sort of relief measures. Survey results also demonstrated an average productivity decline of 25% among employees on days when they had significant allergy symptoms and 30% of employees losing workdays due to uncontrolled allergy symptoms in the past year.5
AR is often misdiagnosed and/ or undertreated.3Patients with AR often present to medical practitioners requesting antibiotics for what they think is a sinus infection when what they need is appropriate treatment for AR. The misdiagnosis of AR contributes to and perpetuates the overuse of oral antibiotics. Retail clinic nurse practitioners (NPs) and physician assistants (PAs) are at the front line of patient care and have a great opportunity to educate patients regarding the commonality and characteristics of AR and offer an evidence-based treatment plan.
This article will review a case study of a patient with AR. The diagnosis and management of AR will be discussed along with evidence-based options for treatment.
Brooke is a 16-year-old girl, accompanied by her father, who presents to your clinic for the first time with the chief complaint of a flare of her allergy symptoms this fall. She states that since her school year started 2 months ago in early August, her “allergies have been terrible.” Brooke has had seasonal allergies since she was 9 years old, and her father states that they have typically controlled Brooke’s symptoms over the past several years with OTC antihistamines and OTC eye drops. He states that he typically sees a spike in Brooke’s allergy symptoms each spring when the trees start blooming, but that her symptoms are much better by July. Brooke reports having difficulty staying awake during her school day, and she is not sure if it is due to the allergy pill she takes in the morning or because her nasal congestion is keeping her awake at night. She is complaining of sneezing, an itchy nose, itchy eyes, clear runny nose, and postnasal drip. Brooke’s father states that the last time she had similar symptoms she was prescribed a 5-day course of antibiotics and wonders if she is getting more antibiotics today.
Brooke recently tried an OTC corticosteroid (fluticasone propionate) nasal spray after she and her father saw a poster about the medicine at her pharmacy. Typically, she only uses her nasal spray when her symptoms are “really bad,” but her current symptoms necessitated her using the nasal spray twice daily for the past 6 weeks. She states she doesn’t like nasal sprays very much because the medication “runs down” the back of her throat. She recently added a second-generation oral antihistamine to her daily medications, but her symptoms persist. She has also tried OTC allergy eye drops as needed and reports her eye symptoms have somewhat improved. When questioned, Brooke states she is adherent with her medications.
DISCUSSION QUESTION: What additional information would you want to know about Brooke’s history and current illness?
ANSWER:A patient’s medical history is critical to an accurate diagnosis. You decide that you need a more detailed medical history from Brooke and proceed to ask her additional questions that elicit the following information:
DISCUSSION QUESTION: What is your initial impression of Brooke’s presentation?
ANSWER:Based on her history, you initially suspect AR. Brooke’s father again asks if she will be prescribed an antibiotic for treatment. You share that without evidence (on exam and/ or radiological imaging) of Brooke having a bacterial infection, there is no indication for antibiotics and that if antibiotics were prescribed in such a scenario, they wouldn’t be beneficial for symptom relief. Brooke’s father is satisfied with your answer. You then move on to Brooke’s physical exam and find the following:
DISCUSSION QUESTION: What would you recommend and/or prescribe for Brooke’s treatment plan?
ANSWER: After Brooke’s exam, you conclude that her symptoms are consistent with seasonal AR and there is no evidence that supports a diagnosis of sinusitis. You review the Joint Task Force Allergic Rhinitis guidelines:
In 2008, a joint task force (JTF), representing the American Academy of Allergy, Asthma and Immunology; the American College of Allergy, Asthma and Immunology; and the Joint Council of Allergy, Asthma and Immunology developed practice parameters for the diagnosis and treatment of rhinitis.1This evidence-based document provides NPs, PAs, and all medical providers a template by which they can make optimal choices for their patient’s treatment. Nasal corticosteroids are considered to be the most effective medication for controlling AR symptoms and, therefore, are considered first-line treatment for AR.1Nasal antihistamines may also be considered for use as first-line AR treatment.1
The JTF ascribes to a stepwise approach for AR treatment (see Figure1,6).According to the practice parameters, AR is controlled if nasal symptoms do not interfere with a patient’s normal daily routine and sneezing, nasal itching, congestion, and eye symptoms occur on fewer than 2 days per week. When this is the case, treatment should remain the same or stepped down as defined in the Figure. Alternatively, if a patient has mild interference with activities and is sneezing or has nasal itching, congestion, or eye symptoms 2 to 6 days per week, treatment should be increased by 1 step. If the patient has severe interference with activities and is sneezing or has nasal itching, congestion, or eye symptoms daily, treatment should be increased by 2 steps.1
Patients with moderate to severe persistent AR are considered candidates for immunotherapy if they fail pharmacotherapy and have evidence of specific immunoglobulin-E antibodies to clinically relevant allergens.
The Rhinitis Control Assessment Test (RCAT) was published in 2013 and provides a validated means to subjectively assess a patient’s nasal allergy symptoms. The RCAT is a simple 6-item patient-completed questionnaire designed to reveal any issues of rhinitis symptom control.
The RCAT asks 6 questions:
1. During the past week, how often did you have nasal congestion?
2. During the past week, how often did you sneeze?
3. During the past week, how often did you have watery eyes?
4. During the past week, to what extent did your nasal or other allergy symptoms interfere with your sleep?
5. During the past week, how often did you avoid any activities (eg, visiting a house with a dog or cat, gardening) because of your nasal or other allergy symptoms?
6. During the past week, how well were your allergy symptoms controlled?
RCAT scores range from 6 to 30, with higher scores indicating better rhinitis control. RCAT scores equal to or less than 21 are consistent with patients who have uncontrolled allergy symptoms, and scores greater than 21 are consistent with patients whose symptoms are controlled. When using the RCAT on consecutive visits, a change of at least 3 points is considered clinically meaningful in the context of a patient’s treatment plan. The RCAT can be used to rapidly screen for patients with rhinitis symptom control problems and can help patients communicate with their providers about their symptoms.7
Prior to discussing pharmacotherapy, you review allergen avoidance measures with Brooke and her father, which include minimizing her exposure to spring and fall pollens. Brooke asks your opinion regarding her interest in adopting a cat and you share that because of her atopic history, she would be a great candidate for allergy skin testing to best determine her related risks, if any.
Because Brooke has previously tried and failed treatment with a corticosteroid nasal spray and oral second-generation antihistamine, you decide to step up her treatment by adding an antihistamine nasal spray. Since the publication of JTF’s practice parameters in 2008, a prescription-only combination corticosteroid/ antihistamine nasal spray has become available (fluticasone proprionate / azelastine HCL). Remembering that Brooke complained of her previous nasal spray “running down” the back of her throat, you choose to minimize the volume of nasal spray that she will be taking daily by starting her on the combination corticosteroid/antihistamine spray. The combination product has a quick onset of action that should help her adhere to the treatment plan because she will be able to realize the benefits of the medication in short order. Additionally, the nasal sprays have minimal somnolence adverse effects. Brooke’s father asks you to review the best way for her to take a nasal spray medication and you review the proper steps with both of them (see Table). You discontinue Brooke’s daily use of cetirizine in hopes that any contribution it made to her being sleepy during the school day would stop. You tell Brooke that she can try an alternative second-generation antihistamine (fexofenadine) at bedtime, if needed. You also share with Brooke the benefits of using a nasal rinse, particularly about 20 minutes prior to taking her prescribed nasal spray. You ask Brooke to start taking her allergy eye drops on a consistent daily basis.
Brooke and her father are well pleased with their visit and believe the treatment plan sets them up for success. Brooke is to follow up in 1 month to reassess her symptoms and determine the effectiveness of her treatment plan. You explain to Brooke that she will be asked to complete the RCAT at her next visit to provide a basis for comparison.
It is widely accepted that the most effective treatment plan for a patient is one that they will follow, is evidence-based, and is created with a patient-centered approach. This case study presents the many aspects of a typical conversation that presents to a retail clinic for a very common diagnosis. Using the JTF’s practice parameters when treating AR while actively listening to the patient will provide a great platform for an effective treatment plan that will optimize the patient’s health outcome.
