The global variation and prevalence of chronic symptoms and the economic impact on the population has not been studied on a global perspective, but has been considered country by country. Among these considerations, an increase in several countries has been recorded, with a more pronounced prevalence in low to mid-income countries. If we look at an example of the epidemiology of a specific disease state where nasal congestion and/or obstruction is present, allergic rhinitis affects one quarter of the world population adverselyimpairing the quality of life, productive work hours, and sleep. In the United States, an estimated 20 million Americans are affected by nasal obstruction, and tens of millions of Americans affected by rhinosinusitis burdening the healthcare system with a cost of $6 billion in healthcare expenditures and one of the costliest physical conditions for healthcare employers. Given the high prevalence of rhinologic disease, to include nasal obstruction and congestion, and the burden of social and economic costs, there continues to be an unmet need in for effective treatment options nationally and globally. Are we doing enough by omitting objective, innovative advancements in nasal measurements to treat patients?
INNOVATION IN NASAL MEASUREMENT: ARE WE DOING ENOUGH FOR PATIENTS?
The objective of this review was to understand how innovation in nasal measurement can address nasal congestion and obstruction, and if we are doing enough to help patients as clinicians treating nasal congestion and obstruction. Secondary data from literature was obtained through a review and examination of the article’s content. The selection of articles for review was based on the study type, article content, the age of the article, and the experience of the end user publishing the information. In an attempt to answer the research question, the following steps in data collection were completed. Over a course of four months, each article was reviewed and examined for specific information to support the objective. To optimize the research, the author chose to focus on the content portion of the literature review relevant to and the validation for the importance of nasal measurements in the allergy patient with strong confidence in the innovation as evident by the enormity of supportive research and literature published over two decades.
Through additional studies, allergic rhinitis with corresponding congestion has become problematic worldwide, and 94% complain of nasal congestion as a primary symptom (Table 1) . Bauchau & Durham,  confirmed the findings supporting the problematic condition of allergic rhinitis in a cross-sectional study of 9646 European adults where 40% of the subjects reported having a previous diagnosis, and symptoms, consistent with allergic rhinitis. The European prevalence of rhinitis is similarly seen as a worldwide condition with lifetime prevalence estimates of between 10% and 20% of the population in the USA, UK, Germany, Switzerland and Finland . Using a conservative estimate, it is proposed that allergic rhinitis occurs in approximately 500million people: Over 100million people in Europe and North America., more than 150million in Asia Pacific, greater than 100million in India, Pakistan and surrounding countries, over 75million in Central and South America, more than 30million in Africa, andover 50million in other countries (Table 2). Among these populations, nearly 200million people also have asthma as co morbidity .
Specific guidelines in clinical practice have become a form of algorithm for diagnosing, testing, treatment, and outcome measurement tools for rhinitis and nasal congestion. These guidelines help practitioners in their decision-making process and contain updates in science and epidemiology. Guidelines for rhinitis are available; however, in 2008, a Phase 3 update to the original report called Allergic Rhinitis and its Impact on Asthma (ARIA) was published in response to innovation and practice. In 1999, the World Health Organization (WHO) and clinical experts created an initiative in a report form to educate and implement management of rhinitis in an evidence based medicine approach used to treat the nearly 500 million patients affected globally .
A phase 4 update of ARIA was completed in 2018, with the Phase 3 ARIA update commencing in 2004. Several chapters of ARIA were extensively reviewed in an evidence based model, and papers were published (or submitted) in peer reviewed journals: tertiary prevention of allergy, complementary and alternative medicine, and pharmacotherapy and anti IgE treatment, allergen specific immunotherapy, links between rhinitis and asthma and mechanisms of rhinitis. There was then a need for a global document based on the published papers to highlight the interactions between the upper and the lower airways and to: Develop an evidence based global document on a key problem of respiratory medicine including diagnosis, epidemiology, common risk factors, management and prevention; propose educational materials for healthcare professionals and patients; meet the objectives of the WHO Global Alliance against Chronic Respiratory Diseases (GARD) in order to help coordinate the efforts of the different GARD organizations towards a better prevention and management of Chronic Respiratory Diseases (CRD), to increase CRD awareness and also to fill some of the gaps in knowledge; focus on the prevention of chronic respiratory and allergic diseases; highlight gaps in knowledge, particularly in developing countries and deprived areas; prepare an executive summary and pocket guide for doctors, patients and healthcare professionals .
“Allergic Rhinitis and its Impact on Asthma (ARIA) have evolved from a guideline using the best approach to Integrated Care Pathways (ICP’s) using mobile technology in AR and asthma multimorbidity. The proposed next phase of ARIA is Change Management (CM) with the aim of providing an active and healthy life to rhinitis sufferers and to those with asthma multimorbidity across the life cycle whatever their gender or socio-economic status in order to reduce health and social inequities incurred by the disease. ARIA has followed the 8-step model of Kotter to assess and implement the impact of rhinitis on asthma multimorbidity and to propose multimorbid guidelines. A second change management strategy is proposed by ARIA Phase 4 to increase self-medication and shared decision making in rhinitis and asthma multimorbidity. An innovation of ARIA has been the development and validation of IT evidence-based tools (MASK: Mobile Airways Sentinel Network) that can inform patient decisions on the basis of a self-care plan proposed by the health care professional [3,9].
Beyond the innovation of using advanced IT resources such as clinical instruments, ARIA has evolved from a guideline using the best practices conventionalized with evidence based medicine to Integrated Care Pathways (ICP’s) using mobile application technology in AR and asthma multimorbidity. “The proposed next phase of ARIA is Change Management (CM) with the aim of providing an active and healthy life to rhinitis sufferers and to those with asthma multimorbidity across the life cycle whatever their gender or socio-economic status in order to reduce health and social inequities incurred by the disease”.

With nearly 500 million people of the global population suffering or affected by the symptoms of allergic rhinitis,  wrote and published a society position statement, EAACI position paper on the standardization of nasal allergen challenges discussing the standardization of nasal allergen challenges. Within this position paper,  discussed and elaborated to leading allergists of theworld that nasal measurements had a high actuality in the treatment of allergy disorders.
The literature review formatting the position statement consisted of 786 documents with 173 selected as suitable studies and papers for review and consideration for the position statement. Throughout the examination of the documents,  standardized the society position for correctly diagnosing and recommending adequate therapy for allergic rhinitis. Within the section of the application of allergens, the objective assessment of nasal patency describes four techniques to assess and quantify nasal airflow, airflow volume, and airflow ventilation. Of the four techniques and methods mentioned, acoustic rhinometry is one of them, in addition to 4-phase rhinomanometry, PNIF, and anterior acoustic rhinometry. The human eye was never able to estimate the measurements of nasal patency; therefore, suggesting the necessity for objective measurements. Augé et al., (2018) stated, “Acoustic rhinometry is quick and easy to perform, without the need of patient collaboration. It was standardizedin 2005 by the standardization committee on objective assessment of the nasal airway of the European Rhinology Society” .
With the innovation of mobile technology to increase patient management, the technology of acoustic rhinometry, in addition to rhinomanometry to measure the airflow function of the upper airway, is used to locate and quantify the level of obstruction within the severity of rhinitis and its effect on asthma . Objective nasal measurements have become an integral part of clinical practice in order to quantify and qualify the level of obstruction beyond the scope of the individual patient directed self-assessments. Beyond the clinical use of the technology, and in conjunction with ARIA, rhinometryand rhinomanometrycan supplement the patient care plan with the cross-sectional area measurements and airway function that has been provided on frequent simultaneous coexistence of inflammatory conditions in the upper airway. These measurements can be integrated into an EMR and reproduced in pdf format for sharing among healthcare providers. The conversion of echo measurements to nasal volume requires mathematical calculations and theoretical assumptions, which is done in real time data analysis by the computer connected to the recording device with four short sound wave firings. In a congested nose, or in the nose with nasal polyps or tumor, the narrowest points are located deeper in nasal cavity, and acoustic rhinometry can detect the position of this point; however, cannot differentiate what is the blocking factor . Acoustic rhinometry is an easy, non-invasive, and non-painful procedure to perform with clear visuals and graphics that examines the entire airway, demonstrates the location and severity of the obstruction, and evaluates the success of treatment and outcomes as shown in the figures. The graphics within the software can be individualized to accommodate the end user and facility as shown in the (Figures 1-8).
Acoustic Rhinometry (AR) by GM Instruments, Ltd  remains the only global clinical and research model that has several attractive features relevant to application in the pediatric and veterinary populations, too. Additional measurement products from GM Instruments, LTs. Include the PNIF and the NR6 Rhino manometer .
Another method of measurement proposed in the literature has been Computational Fluid Dynamics (CFD). This type of test has been conceptualized and compared to rhinometry and rhinomanometry  for ENT use in the literature as far back as 2010, but has never come to fruition as a study due to the cost and the necessary critical improvements needed to become of relevant clinical value; candidly, this type of “industrial” study is way too complex, impractical, and time-consuming to be of value and use in clinical practice . Vogt et al.,  further commented, “The results of rhinometry do correlate with the symptom of nasal obstruction. Some have denied this. As recently as 2005, it was stated “Surgeons are reluctant to use objective measurements as there is general agreement that objective measurements do not correlate with the patient symptoms of nasal obstruction .
1. It provides feedback through real time data for the doctor to refine surgical and medical techniques for results and patient outcomes
2. Nasal measurements quantify improvement of technique and patient outcomes, and if changes in technique are necessary
3. It provides evidentiary documentation of surgical outcomes, pre and post op, should the patient have unnecessary claims or unmet expectations requiring additional testing, which can be inconvenient, expensive, and cause third party payors to evaluate the clinician and practice of defensive medicine
