Inhaler Education in NP Practice: Asthma Management Guide

Introduction

Nurses are the initial point of contact for patients in many medical settings, and nurse practitioners (NPs) are the primary source for delivering basic medical care — including physical examinations, diagnostic tests, counseling, and prescriptions. A large growth in nurse practitioners is being witnessed worldwide due to emerging pandemics; however, NPs have long been invaluable in routine health cases, functioning in settings such as clinics, hospitals, schools, and workplaces. As the first point of medical contact for patients, NPs serve as first-hand problem solvers, guiding patients according to their individual medical needs. This paper analyzes a common health problem faced by NPs — poor inhaler technique education among asthma patients — and recommends medical management strategies. Subsequent sections examine the problem in depth for evaluation and practical suggestions.

Healthcare Problem Identified

Asthma inhalers provide relief to asthma patients because medication is delivered directly into the lungs, preventing disease symptoms. Correct inhaler use is crucial for controlling the disease; however, numerous studies have shown that patients use their asthma devices incorrectly, resulting in uncontrolled asthma. Repeated education is needed, and this should include physical demonstrations of the inhalers, checking whether the patient's technique is adequate, correcting errors, and rechecking for effectiveness. It has also been observed that trained staff are required to better instruct patients, and for this purpose nurse practitioners play an important role. Additionally, the choice of inhaler should depend on cost-effectiveness and affordability so that the patient can use it correctly and sustain compliance.

A study indicated that the metered-dose inhaler (MDI) had the most frequent number of errors: coordination errors accounted for 45 percent, incorrect speed and depth of inspiration for 44 percent, and failure to hold the breath after inhalation for 46 percent (Sanchis, Gich & Pedersen, 2016). Dry powder inhalers (DPIs) were also examined for errors, revealing that incorrect preparation accounted for 29 percent of errors, failure to fully expire before inhalation for 46 percent, and failure to hold the breath after inhalation for 37 percent. The overall prevalence of correct technique was only 31 percent.

These problems emerged soon after metered-dose inhalers were first introduced. Efforts were made to educate patients about proper usage — including regular training programs, printed materials, videos, and software — yet some patients still could not master the required method. Nurse practitioners provided first-hand instruction to simplify the process for both children and adults.

Chronic obstructive pulmonary disease (COPD) and asthma together rank among the most prevalent diseases globally and are leading causes of death for approximately 339 million people worldwide (Bhushan et al., 2018). These conditions account for up to 1,000 deaths per day among children and adults combined. COPD, the fourth leading cause of death, was projected to rise to third place by 2020. Various studies have indicated that improper inhaler use has contributed to increased rates of both asthma and COPD and a corresponding surge in hospital visits. Poor inhalation technique — often resulting from missing at least one critical step and from low health literacy — has been identified as the primary driver of increased clinical visits.

Poor technique has been linked to factors such as age, sex, educational level, and emotional state (Milanese et al., 2019). Younger asthmatic patients have reported more device mishandling, resulting in poorer disease control. In older patients, COPD is more common but still requires prescribed medications, including inhalers; high rates of poor device handling among this group induce severe exacerbations.

Epidemiologically, children have been more prone to asthma than adults, though cross-national comparisons are complicated by differing age definitions for asthma status (Dharmage, Perret & Custovic, 2019). In older populations, co-morbidity rates are difficult to define because asthma symptoms may overlap with breathlessness, COPD, or heart failure. Environmental exposure in early childhood is a primary cause of early-onset asthma. In utero parental smoking can provoke asthma in young children; studies indicate that female smokers are more likely to have asthma than non-smokers, though this finding may not apply equally to men. Outdoor air pollutants globally compromise air quality for children and adults, heavily affecting asthmatic patients. Indoor allergens also carry intense effects on asthmatic individuals. Occupational exposures are increasingly recognized, giving rise to two categories: work-aggravated asthma (WAA) and occupational asthma (OA). Lifestyle factors, including westernization and dietary habits, further influence asthma severity.

Pathophysiologically, the rise in asthma cases in western cultures has partly been attributed to overly clean environmental conditions, which reduce exposure to environmental microorganisms and lower immune resistance. When individuals then encounter outdoor air, pollutants enter the lungs and disturb immune function more readily. Bronchiolar inflammation follows, producing less resistance against asthma triggers. This inflammation damages the trachea and bronchi, accelerating increased mucus production and decreased mucus clearance.
