Asthma patients' self-reported behaviours toward inhaled corticosteroids

Pharmacological treatment of asthma in Sweden from 2005 to 2015

OBJECTIVE

Despite access to effective therapies many asthma patients still do not have well-controlled disease. This is possibly related to underuse of inhaled corticosteroids (ICS) and overuse of short-acting β2-agonists (SABA). Our aim was to investigate longitudinal trends and associated factors in asthma treatment.

METHODS

Two separate cohorts of adults with physician-diagnosed asthma were randomly selected from 14 hospitals and 56 primary health centers in Sweden in 2005 (n = 1182) and 2015 (n = 1225). Information about symptoms, maintenance treatment, and use of rescue medication was collected by questionnaires. Associations between treatment and sex, age, smoking, education, body mass index (BMI), physical activity, allergic asthma, and symptom control were analyzed using Pearson's chi2-test. Odds ratios (ORs) were calculated using logistic regression.

RESULTS

Maintenance treatment with ICS together with long-acting β2-agonists (LABA) and/or montelukast increased from 39.2% to 44.2% (p = 0.012). The use of ICS + LABA as-needed increased (11.1-18.9%, p < 0.001), while SABA use decreased (46.4- 41.8%, p = 0.023). Regular treatment with ICS did not change notably (54.2-57.2%, p = 0.14). Older age, former smoking, and poor symptom control were related to treatment with ICS + LABA/montelukast. In 2015, 22.7% reported daily use of SABA. A higher step of maintenance treatment, older age, obesity, shorter education, current smoking, allergic asthma, low or very high physical activity, and a history of exacerbations were associated with daily SABA use.

CONCLUSIONS

The use of ICS + LABA both for maintenance treatment and symptom relief has increased over time. Despite this, the problem of low use of ICS and high use of SABA remains.

Mild asthma: Conundrums, complexities and the need to customize care

Mild and moderate asthma cover a wide range of asthma presentations, phenotypes and symptom burden, and account for the majority of people with asthma worldwide. Mild asthma has been difficult to define because of its heterogeneity and wide spectrum of impact and outcomes, including being associated with severe exacerbations. Assessment of mild-moderate asthma is best made by combining asthma symptom control and exacerbation risk as the principle means by which to determine treatment needs. Incontrovertible evidence and guidelines support treatment initiation with anti-inflammatory medication, completely avoiding reliever-only treatment of mild asthma. Shared decision making with patients and a treatable traits approach will ensure that a holistic approach is taken to maximize patient outcomes. Most importantly, mild asthma should be regarded as a reversible, potentially curable condition, remaining in long-term remission through minimizing triggers and optimizing care.

Effects of Framed Mobile Messages on Beliefs, Intentions, Adherence, and Asthma Control: A Randomized Trial

We aimed to examine the effects of framed mobile messages (messages emphasizing losses or gains because of a behavior) on young adults' beliefs about their daily Inhaled Corticosteroids (ICS), intentions to take their ICS, adherence, and asthma control. College students (18-29 years) who owned a mobile phone and had a diagnosis of asthma with a prescription for an ICS were recruited. Participants (n = 43) were randomized to receive either gain- or loss-framed mobile messages three times per week for eight weeks. Engagement rates with messages were calculated. Outcomes included beliefs, intentions, adherence, and asthma control. Data collection was performed at baseline, week 4, and week 8. Mixed-design ANOVA assessed whether outcomes improved differentially from baseline to week eight between gain- and loss-framed groups. Twenty-two participants were randomly assigned to the gain-framed group and 21 to the loss-framed group. There was a 100% retention rate. The engagement rate with the text messages was 85.9%. There was a significant difference in participants' intentions to take medication and asthma control from baseline. There were no significant changes in other outcomes from baseline. There was no difference in changes in all outcomes between participants receiving gain- versus loss-framed messages. Framed mobile messages improved young adults' asthma control and intentions to take their medication as prescribed.

Correlation Analysis of the Therapy Adherence to Long-Acting Inhalers Among Patients with Stable COPD

Purpose

Long-acting inhalers are the mainstay maintenance therapy for stable chronic obstructive pulmonary disease (COPD) management. The aim of this study was to assess adherence to inhalers among adults with COPD in China and to develop strategies to improve adherence for the next step.

Patients and Methods

A cross-sectional study was conducted among 246 adult patients with COPD using long-acting inhalers to explore different demographic characteristics, disease characteristics and medication regimens. Adherence to inhalers was assessed using the Medication Adherence Report Scale (MARS).

Results

Among the 246 patients included in the present study, 93 (37.80%) had good adherence, while 153 (62.20%) had poor adherence. From the comparison of patients with good and poor adherence, we found that the course of disease and education background had a significant effect on adherence (p < 0.05). Among the LAMA therapy group, inhaled tiotropium bromide spray (Ingelheim am Rhein, Germany) with active release technology had better adherence than inhaled tiotropium bromide powder (Ingelheim am Rhein, Germany) (p < 0.05). Moreover, COPD patients with good adherence had better pulmonary function and fewer moderate or severe exacerbations in the past year (p < 0.05).

Conclusion

The factors affecting the use of inhalers in patients with stable COPD are complicated. Medical staff should select appropriate inhalers according to the patient's disease status and duration and provide medication education to improve adherence.

The Efficacy and Safety of First-Line Single-Inhaler Triple versus Dual Therapy in Controller-Naïve and Symptomatic Adults with Asthma: A Preliminary Retrospective Cohort Study

Purpose

The efficacy and safety of first-line triple and dual therapy remain unclear because the stepwise strategy is a worldwide standard in controller-naïve asthma. A preliminary retrospective cohort study was conducted to investigate the efficacy and safety of first-line triple and dual therapy for managing controller-naïve and symptomatic adult patients with asthma.

Patients and Methods

Patients with asthma who received first-line single-inhaler triple therapy (SITT) or dual therapy (SIDT) for at least 8 weeks were selected between December 1, 2020, and May 31, 2021, in Fujiki Medical and Surgical Clinic, Miyazaki, Japan. Data on daytime and nighttime visual analog scale (VAS) scores, lung function tests, fractional exhaled nitrogen oxide (F_ENO), and adverse events were compared between SITT and SIDT pre- and post-treatment.

Results

The SITT significantly improved the nighttime, but not daytime, VAS scores better than the SIDT 2 weeks post-treatment (P = 0.0026), whereas SITT and SIDT significantly improved daytime and nighttime VAS scores after treatment compared to baseline. Both therapies also significantly improved lung functions and F_ENO post-treatment. The proportion of patients achieving complete control in the nighttime VAS scores after SITT was significantly higher than that four (P = 0.0186) and 8 weeks (P = 0.0061) after SIDT. Only patients with SITT experienced dry mouth.

Conclusion

Our study demonstrated that first-line SITT and SIDT were effective, and SITT improved disease control faster than SIDT in controller-naïve and symptomatic adult patients with asthma. The first-line SITT may contribute to faster and better control levels in symptomatic patients with asthma.

Treatment of Allergic Rhinitis and Asthma in Primary Care: Dispensations Do Not Align with Prescriptions

Background

Appropriate use of effective treatments is required for satisfactory control of allergic symptoms. Coherent medical care -regular prescribing by the same Health Care Professionals- is a preliminary need.

Objective

We investigated the numbers of distinct prescribers, the regularity of medical visits, and the agreement between prescriptions and associated dispensations in individual patients with perennial allergic rhinitis (PAR) and asthma.

Methods

In primary care electronic health records (EHRs), a cohort of patients with PAR and asthma was identified. Individual EHRs were linked to corresponding claims recording all dispensations. Prescribing patterns were analyzed for the major treatment classes, and the dispensations linked to individual prescriptions were retrieved to compute the proportions of days covered (PDCs) for asthma and PAR therapy.

Results

A total of 3654 patients were included, with 62% being female (mean age, 46.1 years). At inclusion, asthma control was not optimal in 51% of the patients and 48% had received oral corticosteroids. The mean interval between successive prescriptions varied between 93 (leukotriene receptor antagonists, LTRAs) and 103 (inhaled corticosteroids, ICS) days, and 97 (antihistamines, AHs) and 103 days (nasal corticosteroids, NCS). On average, individual prescriptions lead to 1.2, 1.5, 1.7 and 1.8 dispensations of ICS, ICS/Long-Acting Beta-Agonist (LABA) fixed-dose combinations, LABAs, and LTRAs, respectively, and to 1.3 and 1.6 dispensations of NCS and AHs, respectively. PDCs then varied between 37.8% for ICS and 58.6% for LTRAs, and between 39.7% for NCS and 50.4% for AHs. Care was nonetheless coherent, with >90% of all dispensations related to prescriptions issued by single General Practitioners (GPs).

Conclusion

Despite regular healthcare visits and medication prescriptions, allergic patients only partly and selectively refilled their treatments, preferring the less effective therapy, in a context of poor control of asthma symptoms.

Daytime and Nighttime Visual Analog Scales May Be Useful in Assessing Asthma Control Levels Before and After Treatment

PURPOSE

Few questionnaires evaluate daytime and nighttime symptoms separately, although these assessments could contribute to the improvement of disease control levels and prevention of future risks in asthma. The purpose of this retrospective study was to investigate whether daytime and nighttime visual analog scales (VAS) are useful in measuring the perception of symptoms, assessing disease control levels, and evaluating the treatment effects in asthma.

PATIENTS AND METHODS

Self-reporting asthma control tests (ACT) before and after treatment are standardized tests used to determine disease control levels. A multiple regression analysis was performed to determine the correlation between daytime and nighttime VAS and the characteristics of patients before treatment, as well as the changes in VAS and lung functions and fractional exhaled nitrogen oxide after treatment in 55 treatment-naïve symptomatic adult patients with asthma.

RESULTS

Both daytime (r = -0.57, P < 0.0001) and nighttime (r = -0.46, P < 0.0001) VAS correlated well with ACT scores, and there was a correlation between daytime and nighttime VAS (r = 0.33, P = 0.0148) before treatment. In addition, the changes in daytime (r = -0.65, P < 0.0001) and nighttime (r = -0.44, P < 0.0001) VAS were significantly associated with changes in the ACT scores. The multiple regression analysis (β [95% confidence interval]) revealed that improvements in the daytime (-2.33 [-4.55 to -0.11], P = 0.0405) and nighttime (-3.09 [-6.25 to 0.07], P = 0.0505) VAS were associated with an increased forced vital capacity after treatment, although there was no correlation between the VAS and characteristics before treatment.

CONCLUSION

Our study demonstrated that daytime and nighttime VAS were useful in assessing disease control levels and evaluating the treatment effects in asthma.

Determining Persistence with an Inhaled Corticosteroid in Asthma: Assessment Using an Objective Measurement vs the Self-Reported Foster Score

INTRODUCTION

Adherence with controller medication is a major challenge in asthma management. Thus, a reliable method of measurement is mandatory to assess adherence.

AIM

To examine the test-retest reliability on adherence with inhaled corticosteroids in adults with asthma using, a self-reported adherence score (Foster score).

METHODS

Patients with asthma and >1 routine follow-up appointment at a university hospital outpatient clinic reported Foster scores. The objective Medication Possession Ratio (MPR) was calculated based on pharmacy redemption data and physician-prescribed doses of inhaled corticosteroids. The difference between Foster score and MPR at the first and second visit was assessed using a Bland-Altman plot, outcomes reported as limits of agreements and bias. Foster scores from both visits were used to calculate an intraclass correlation coefficient (ICC).

RESULTS

Self-reported adherence with asthma controller medication measured by Foster score was significantly higher than the objective MPR (p < 0.0001). The Bland-Altman plot for MPR and Foster score at the first and second visit showed upper and lower limits of agreement of 83.5 - (-1.6) and 80.9 - (-6.9) and bias was 41.0 and 37.0, respectively. Of the included patients, 93.1% reported identical Foster scores between visits, resulting in an excellent ICC of 0.92. Absolute median difference between Foster scores and MPR at first and second visit was 8.7 percentage points (p = 0.049).

CONCLUSION

Foster score shows an excellent ICC; however, its poor agreement with objective measures of adherence suggests that clinicians should not rely on Foster scores alone to assess adherence with inhaled corticosteroids in patients with asthma.

Adherence to Inhaled Corticosteroid Therapy and Its Clinical Impact on Asthma Control in Adults Living with Asthma in Northwestern Ethiopian Hospitals

BACKGROUND

Inhaled corticosteroids (ICS) are the backbone of and primary choice for long-term asthma control therapy; however, the level of adherence to this regimen has not yet been investigated, particularly in the study area of Northwest Ethiopia. Therefore, this study aimed to examine the level of adherence to ICS treatment and its impact on adults living with asthma in Northwestern Ethiopian hospitals.

MATERIALS AND METHODS

A multicenter institution-based survey was conducted in asthma patients treated with ICS-based regimens in public hospitals in Northwest Ethiopia. Adherence to ICS was measured with the Medication Adherence Report Scale for Asthma. Descriptive statistics were used to present respondents' characteristics, and logistic regression was used to test associations between predictors and outcome variables. A level of p<0.05 was used as a cut-off point for a significant association.

RESULTS

Of a total of 422 approached subjects, 96.7% completed the survey. The mean (±SD) age of the participants was 49.82 (±16.1) years. The majority of participants (86.1%) had a low level of adherence to ICS treatment. A significant proportion (42%) of the respondents reported that they utilized ICS only before performing exercises that made them breathless. Around two-fifths of the participants used ICS either when they needed it or when they felt breathless. Furthermore, one-third of the study subjects reported that they either avoided or forgot to take ICS. Participants who had access to free healthcare services had better adherence to ICS (p=0.01), and non-adherence to ICS therapy was significantly associated with poor levels of asthma control (p≤0.001).

CONCLUSION

This study found that adult patients with asthma had low levels of adherence to ICS therapy. Future prospective research in a larger population, focusing on identifying the obstacles to ICS adherence in patients living with asthma and creating successful intervention options, is recommended.

[Patient expectations in asthma care]

Asthma, a common chronic disease characterized by variable levels of severity, requires patient-centered management to achieve the best health outcomes. Studies have highlighted the gap between consensus management recommendations and patient goals, which represent a potential source of therapeutic wandering and of poor compliance. Patient expectations are continually evolving and are dependent on knowledge, feelings and individual experience. From this perspective, listening carefully to patients and caregivers makes it easier to exchange views and define common goals. The active participation of patients at all levels of decision-making and transmission of information may improve asthma control and other quality of life parameters.

Drug-related factors affecting medication adherence among Egyptian asthma patients

Background

The aim of this study is to evaluate adherence to inhaler therapy in asthmatic patients and examine drug-related factors affecting medication adherence among Egyptian asthma patients. The study was carried out among 110 clinically diagnosed asthma patients attending at a university hospital, Sohag, Egypt. Inhaler criteria and adherence were evaluated by a standardized tool “Morisky Medication Adherence Scale (MMAS), 2008.”

Results

The study revealed that out of 110 patients, 42.2% had a high level, 22.9% had medium level, and 34.9% had a low level of medication adherence. There was no relationship between demographic data and medication adherence in asthmatic patients. However, good adherence was frequently encountered among asthmatic patients who used inhaler twice daily, who used drugs its onset of action 5-20 min, who used aerolizer and turbo haler devices, and who used budesonide and budesonide/formoterol.

Conclusions

Poor adherence to inhaler therapy is high in patients with bronchial asthma attending Sohag University Hospital in Upper Egypt. There was a strong relationship between inhaled drug criteria and degree of adherence in asthmatic patients.

Inhaled corticosteroid beliefs, complementary and alternative medicine in children presenting to the emergency department for asthma

OBJECTIVE

Negative beliefs about inhaled corticosteroids (ICS) and endorsement of complementary and alternative medicine (CAM) have been associated with medication non-adherence and uncontrolled asthma. The association of CAM and negative health beliefs is not described in children in acute care settings. Our study objective is to determine the relationship between negative ICS beliefs, CAM use and poorly controlled asthma among a predominantly Latino population in an acute care setting.

METHODS

The study was conducted in the pediatric emergency department of a children's hospital. During an ED asthma encounter, validated questionnaires surveyed parents about negative ICS beliefs, CAM use, and asthma health and control. We compared asthma health reports between parents who did or did not endorse negative ICS beliefs or CAM use, by chi-squared test (or a Fisher's exact test where appropriate).

RESULTS

Parents of 174 children identified mostly as Latino with Medicaid insurance and high asthma morbidity. CAM endorsement and negative ICS beliefs were both associated with increased use of lifetime glucocorticoid (p = 0.03 and p=0.01 respectively). While CAM endorsement was associated with less hospitalizations (p = 0.04) and parental report of asthma "getting better" (p = 0.01), CAM users reported trouble with paying for rent or food (p = 0.02). Negative ICS beliefs and CAM endorsement were not associated with medication adherence.

CONCLUSIONS

Negative ICS beliefs are associated with higher number of oral glucocorticoid courses. The association between CAM endorsement and asthma control is varied, but mostly in favor of improved control. Financial difficulties may make CAM use more likely.

Health literacy among asthma patients and treatment expectations: results of a Belgian survey

Objectives: Non-adherence to asthma medication can lead to lower disease control and asthma exacerbations that may be fatal. This survey assessed the attitude and expectations of Belgian asthma patients towards their treatment.Methods: This cross-sectional survey was conducted between June 2015 and February 2016 in 70 Belgian pharmacies. Participants completing the survey had to be ≥15 years, diagnosed with asthma, and on inhaled corticosteroid-based treatment. The analysis included 80 completed questionnaires.Results: Participants comprehended well that controller drugs are intended to prevent the occurrence of asthma symptoms and complications, and their long-term daily use should be maintained. Twenty seven percent of participants indicated fear of side effects concerning long-term daily use of a controller inhaler. Participants had a good understanding that quick-relief drugs are intended to (quickly) relieve asthma symptoms and do not need to be used on a systematic, daily basis. Out of 73 participants on long-term controller drugs, 33 (45%) were 'non-adherent' (used less frequently than prescribed). Suboptimal adherence to maintenance treatment appeared to increase nightly awakenings and the risk of restrictions in activities due to asthma. Out of 54 participants with available quick-relief drug adherence data, 18 (33%) were non-adherent (used their quick-relief drug more frequently than prescribed).Discussion: This survey confirms suboptimal adherence to maintenance controller therapy and overuse of short-acting reliever medications among Belgian patients, which affects asthma control and quality of life. A substantial proportion of patients expressed fear about their chronic therapy, indicating the need for patient education about their disease and its management.

Assessing Adherence to Inhaled Corticosteroids Among Adults with Asthma in Kuwait Using the Medication Adherence Report Scale for Asthma

PURPOSE

Inhaled corticosteroids (ICS) are the mainstay maintenance therapy for asthma management. Non-adherence to ICS, which can lead to exacerbations and poor asthma control, is commonly reported among adult patients with asthma. The level of adherence to ICS among adult patients with asthma in Kuwait has not been previously published. The aim of this study was to assess adherence to ICS among adults with asthma in Kuwait.

PATIENTS AND METHODS

A cross-sectional study was conducted among adult patients with asthma using ICS therapy at ambulatory asthma clinics in Kuwait. Adherence to ICS was assessed using the Medication Adherence Report Scale for Asthma (MARS-A). Descriptive and logistic regression analyses were conducted using SPSS version 23.

RESULTS

One hundred and forty-nine patients with a mean age of 41.42 (12.75) years participated in the study. The majority of the participants (82.6%) reported low adherence to ICS. Approximately, three-quarters of the participants reported that they used ICS either when needed or when they felt breathless. Furthermore, about half of them admitted that they tried to avoid using ICS (46.3%), or forgot to take ICS (51%), or only used ICS before performing an exercise that made them breathless (54%). In the multivariate logistic regression analysis, independent predictors (age, education, and smoking status) were not found to significantly influence the overall adherence to ICS therapy.

CONCLUSION

Adherence to ICS among adult patients with asthma was found to be low in ambulatory care settings in Kuwait. Future studies should aim to determine the barriers to ICS adherence among patients with asthma, with a focus on developing effective intervention strategies.

The Association Between Beliefs and Adherence to Inhaled Controller Medication Among Older Adults with Asthma: A Cross-Sectional Study in Primary Care

BACKGROUND

While illness perceptions and medication beliefs have been shown to be associated with inhaled corticosteroid (ICS) adherence in younger adults with asthma, their impact on older adults is less understood. This study aimed to determine the prevalence of ICS adherence among older Asian adults and to assess the association between ICS adherence, illness perceptions and medication beliefs.

METHODS

A questionnaire survey on older multi-ethnic Asian patients, aged ≥60 years, with physician-diagnosed asthma, was conducted in two Singapore public primary care clinics. The scores of the Medication Adherence Report Scale for asthma (MARS) were computed to determine the adherence to ICS alone or in combination with LABA. Illness perceptions and medication beliefs were assessed by the scores from the Brief-Illness Perception Questionnaire (B-IPQ) and Beliefs about Medications Questionnaire (BMQ), respectively. Logistic regression analyses were used to identify factors associated with ICS adherence.

RESULTS

Analyses of 323 participants (57% males; Chinese 73.7%, Malay 12.7%, Indian 12.4%; mean age 71.5 years) showed that 40.9% of them had good adherence to ICS (mean MARS score≥4.5). Good adherence to ICS was associated with perception of asthma as a chronic illness (OR=1.22; 95% CI=1.10-1.35; p<0.001), belief of ICS as an essential medication (2.67; 1.76-4.06; p<0.001) and fewer concerns about its use (0.39; 0.26-0.60; p<0.001). Patients on combined ICS-LABA therapy had higher adherence (2.50; 1.41-4.44; p=0.02) than those on ICS monotherapy.

CONCLUSION

Four in ten older patients with asthma were adherent to ICS. Perception of medication necessity, chronicity of illness, concerns and use of ICS-LABA medication were associated with adherence.

Relación entre representación de enfermedad, representación del tratamiento y adherencia en adultos con asma: Una revisión

La adherencia al medicamento de control es el pilar fundamental para el control del asma; sin embargo, se ha identificado que una representación negativa de la enfermedad y el tratamiento impactan de modo negativo en esta. Se hizo una revisión narrativa para identificar los estudios empíricos acerca de representación de enfermedad, representación del tratamiento y adherencia a medicamentos de control en adultos con asma, desde el modelo de sentido común y representación de la enfermedad (MSCRE). Se identificaron 17 estudios divididos en transversales y longitudinales (12), experimentales (3) y de intervención (2), reportando que las principales dimensiones del MSCRE asociadas con la adherencia son la necesidad del tratamiento, preocupación, control de la enfermedad y del tratamiento, temporalidad crónica y consecuencias. Se concluye que el MSCRE es un modelo psicológico que tiene aplicaciones en la investigación y atención clínica para explicar y promover conductas de adherencia a medicamentos de control en adultos con asma.

"I did not know it was so important to take it the whole time" - self-reported barriers to medical treatment among individuals with asthma

BACKGROUND

Asthma is an extensive public health problem and inadequate disease control is not uncommon. Individuals' self-perceived barriers to medical treatment for the entire treatment chain (from seeking care for symptoms to using a medicine) have seldom been studied for chronic diseases such as asthma. The aim of this study was to explore self-perceived barriers to medical treatment among individuals with asthma within the framework of AAAQ (availability, accessibility, acceptability and quality).

METHODS

Individuals with asthma visiting the asthma nurse at a primary health care centre, and who currently had a prescription for anti-asthmatic medicines, were informed about the study. The nurse asked the persons for their consent to be contacted by an interviewer. The interview guide was constructed from the elements of AAAQ exploring self-perceived barriers to asthma treatment. Interviews were conducted in Swedish, English, Arabic and Persian. They were transcribed verbatim and a manifest content analysis was conducted.

RESULTS

Fourteen interviews were conducted. There was a large variation in both age and reported number of years with asthma. Self-perceived barriers to asthma treatment were experienced throughout the whole treatment chain. Barriers that emerged were health care accessibility, perceived quality of care, beliefs about medicines, life circumstances, knowledge gap about asthma and medicines, practical obstacles to using medicines, and experiences with treatment. The self-perceived barriers cover all four elements of AAAQ, but there are also some barriers that go beyond those elements (life circumstances and practical obstacles to using medicines).

CONCLUSIONS

Self-perceived barriers among individuals with asthma cover the whole treatment chain. We want to highlight the inadequate information/education of patients leading to knowledge gaps about both disease and the effect of medicines, and also the perceived unsatisfactory treatment at the PHCC, which could partly be counteracted if patients know what to expect from health care visits.

Pharmacological treatment of asthma in a cohort of adults during a 20-year period: results from the European Community Respiratory Health Survey I, II and III

Asthma often remains uncontrolled, despite the fact that the pharmacological treatment has undergone large changes. We studied changes in the treatment of asthma over a 20-year period and identified factors associated with the regular use of inhaled corticosteroid (ICS) treatment.

Changes in the use of medication were determined in 4617 randomly selected subjects, while changes in adults with persistent asthma were analysed in 369 participants. The study compares data from three surveys in 24 centres in 11 countries.

The use of ICSs increased from 1.7% to 5.9% in the general population and the regular use of ICSs increased from 19% to 34% among persistent asthmatic subjects. The proportion of asthmatic subjects reporting asthma attacks in the last 12 months decreased, while the proportion that had seen a doctor in the last 12 months remained unchanged (42%). Subjects with asthma who had experienced attacks or had seen a doctor were more likely to use ICSs on a regular basis.

Although ICS use has increased, only one-third of subjects with persistent asthma take ICSs on a regular basis. Less than half had seen a doctor during the last year. This indicates that underuse of ICSs and lack of regular healthcare contacts remains a problem in the management of asthma.

Despite increased ICS use, only 34% of subjects with persistent asthma take ICSs on a regular basis; <50% have seen a doctor in the last year. Underuse of ICSs and lack of regular healthcare contacts remains a problem in asthma.http://ow.ly/GUZ630mZkVN

Treatment perceptions in patients with asthma: Synthesis of factors influencing adherence

BACKGROUND

Non-adherence to asthma treatment is a contributing factor for poorly controlled asthma.

AIM

The aim of this systematic review is to explore patients' perceptions of their inhaled asthma treatment, and how these relate to adherence, using both qualitative and quantitative data.

METHODS

Pre-determined search terms and inclusion criteria were used to search electronic databases (The Cochrane Library, MEDLINE, EMBASE and PsycINFO). Two researchers screened titles and abstracts using the Rayyan web app and data were extracted in relation to psychological components (beliefs about, and attitudes towards, medicines) and adherence.

RESULTS

Of 1638 papers, 36 met the inclusion criteria. Key themes were: Perceived need for treatment - all 12 studies using the BMQ to measure patients' perceived need for treatment found that patients' beliefs about their necessity for treatment were associated with adherence-; Concerns about treatment - immediate and long-term side effects (58%), worries about safety (19%), and potential addiction to asthma medication (31%)-; and Perceived social stigma - 22% of studies reported that embarrassment contributed to poor adherence.

CONCLUSIONS

Acknowledging and addressing patient treatment beliefs and perceptual barriers to adherence is integral to designing adherence interventions for asthma patients. Further research is needed to better our understanding of the relationship between treatment perceptions and adherence.

Long-Term Inhaled Corticosteroid Adherence in Asthma Patients with Short-Term Adherence

BACKGROUND

Although the use of inhaled corticosteroids (ICS) in asthma is known to be overall erratic, the long-term use of ICS by patients selected during an episode of regular use is poorly documented.

OBJECTIVE

In a cohort of patients with asthma regularly acquiring ICS therapy over several months, we verified whether these patients remained treated in the following 12 months. The correlates of regular ICS use over this period were investigated.

METHODS

A historical cohort of patients with asthma was identified from the Echantillon généraliste de bénéficiaires national French health care reimbursement data (2007-2012). Patients (6-40 years) were selected during a regular ICS use episode, with 3 or more ICS refills within 120 days. Continuous multiple-interval measures of medication availability (CMA) were computed for the 12 months after the third dispensation, and the factors associated with a CMA value of 80% or more (adherent patients) were identified.

RESULTS

Among 5096 patients (42.1% children/teenagers, 48.8% females), only 24.0% had a CMA value of 80% or more (mean CMA = 54.4%) over the 12 months following the ICS selection period. Achieving a CMA value of 80% or more was primarily associated with being a child/teenager (P = .002), having more severe or less controlled asthma (P = .007), more previous dispensing of short-acting beta agonists (P < .0001), and receiving devices with 200 unit doses (P < .0001). Adherent patients had more frequent general practitioner visits (P < .0001), more distinct prescribers of respiratory therapy (P = .0002), and more frequent switches of ICS (P < .0001).

CONCLUSIONS

Most patients with asthma selected during an episode of regular ICS use did not maintain therapy over the following months. Adherence should be repeatedly monitored, and the reasons for discontinuation should be investigated, at prescriber and patient levels.

eHealth in the future of medications management: personalisation, monitoring and adherence

BACKGROUND

Globally, healthcare systems face major challenges with medicines management and medication adherence. Medication adherence determines medication effectiveness and can be the single most effective intervention for improving health outcomes. In anticipation of growth in eHealth interventions worldwide, we explore the role of eHealth in the patients' medicines management journey in primary care, focusing on personalisation and intelligent monitoring for greater adherence.

DISCUSSION

eHealth offers opportunities to transform every step of the patient's medicines management journey. From booking appointments, consultation with a healthcare professional, decision-making, medication dispensing, carer support, information acquisition and monitoring, to learning about medicines and their management in daily life. It has the potential to support personalisation and monitoring and thus lead to better adherence. For some of these dimensions, such as supporting decision-making and providing reminders and prompts, evidence is stronger, but for many others more rigorous research is urgently needed.

CONCLUSIONS

Given the potential benefits and barriers to eHealth in medicines management, a fine balance needs to be established between evidence-based integration of technologies and constructive experimentation that could lead to a game-changing breakthrough. A concerted, transdisciplinary approach adapted to different contexts, including low- and middle-income contries is required to realise the benefits of eHealth at scale.

[Therapeutic adherence in asthma in France: A general review]

INTRODUCTION

Adherence in asthma is a paramount issue of disease management. A general review of the French publications on this topic has been conducted.

METHODS

Research equations used for bibliographic databases (MEDLINE, Science Direct, Banque de données en santé publique, Cochrane and Cairn.info) comprised the following keywords: "asthma", "therapeutic adherence" and "France". These publications unrelated to asthma, focused on asthma management without exploring adherence, or those conducted in populations without French patients were excluded.

RESULTS

A total of 82 articles have been selected (36 surveys, 4 randomized trials and 42 reviews/syntheses). Whatever the methodology used and publication year, the inadequate therapeutic adherence in asthma was steadily reported, notably for controllers and the quality of use of inhaled devices.

CONCLUSION

The present review highlights the sustainability of adherence-related issues in asthma and the need to improve patients' knowledge on asthma and the finality of therapy. It also highlights the need of an improved communication between patients and physicians is also advocated. Further studies with more recent data are desirable to assess changes in disease management of asthma and the impact of potential future corrective interventions.

Factors associated with overestimation of asthma control: A cross-sectional study in Australia

OBJECTIVE

To investigate actual and perceived disease control in Australians with asthma, and identify factors associated with overestimation of asthma control.

METHODS

This was a cross-sectional study of Australian adults with asthma, who were recruited via Facebook to complete an online survey. The survey included basic demographic questions, and validated tools assessing asthma knowledge, medication adherence, medicine beliefs, illness perception and asthma control. Items that measured symptoms and frequency of reliever medication use were compared to respondents' self-rating of their own asthma control. Predictors of overestimation of asthma control were determined using multivariate logistic regression.

RESULTS

Of 2971 survey responses, 1950 (65.6%) were complete and eligible for inclusion. Overestimation of control was apparent in 45.9% of respondents. Factors independently associated with overestimation of asthma control included education level (OR = 0.755, 95% CI: 0.612-0.931, P = 0.009), asthma knowledge (OR = 0.942, 95% CI: 0.892-0.994, P = 0.029), total asthma control, (OR = 0.842, 95% CI: 0.818-0.867, P < 0.001), agreement that most medications are addictive (OR = 1.144, 95% CI: 1.017-1.287, P = 0.025), and increased feelings of control over asthma (OR = 1.261, 95% CI: 1.191-1.335), P < 0.001).

CONCLUSIONS

Overestimation of asthma control remains a significant issue in Australians with asthma. The study highlights the importance of encouraging patients to express their feelings about asthma control and beliefs about medicines, and to be more forthcoming with their asthma symptoms. This would help to reveal any discrepancies between perceived and actual asthma control.

Knowledge and perceptions of asthma in Zambia: a cross-sectional survey

BACKGROUND

Zambia is currently experiencing an epidemiological transition, from communicable to non-communicable diseases. The annual rate of physician-diagnosed asthma is estimated at 3 %. However, the general public's knowledge of asthma symptoms and signs, and their perception of asthma remain unknown. A survey was conducted aiming to determine knowledge and perceptions of asthma among Zambians.

METHODS

Adults and adolescents attending four clinics in the capital, Lusaka, were surveyed using a standardized questionnaire from July 2011 to March 2012.

RESULTS

Data from 1,540 participants (mean age 30.7 years, 65% female) were collected. Most patients (74%) were living in low-cost housing. One hundred and sixteen (7.6%) participants reported either a medical diagnosis of asthma or currently taking asthma medications. The most frequent asthma symptoms reported were wheezing (88%), and waking up at night with either shortness of breath (85%), chest tightness (85%), or cough (67%). Medications used to treat asthma were mostly oral short-acting beta-agonists (SABA) (59%), inhaled SABA (30.2%) and antibiotics (29.8%). Inhaled steroids were only used by 16.4% while less than 1% were on long-acting beta-agonists (LABA). Many misconceptions were identified among the entire surveyed population with only 54.7% believing hospitalisations are not preventable, 54.7% believing asthma symptoms can be prevented with the right medications and 37% believing inhalers are addictive. Nearly 60% thought that people with asthma cannot exercise or play hard. Significantly more individuals with asthma compared to those without thought tablets are better than inhalers for the treatment of asthma (46% vs 30%).

CONCLUSIONS

We conclude that knowledge on asthma is poor in Zambia, where there remains many misconceptions on asthma and its management.

Asthma inhaler adherence determinants in adults: systematic review of observational data

Nonadherence to inhaled medication leads to poor asthma control and increased healthcare utilisation. Many studies exploring adherence determinants have been conducted, but summaries of the evidence are scarce. We performed a systematic review of observational research on determinants of asthma inhaler adherence among adults. We searched for articles in English reporting quantitative observational studies on inhaler adherence correlates among adults in developed countries, published in EMBASE, Medline, PsychInfo and PsychArticles in 1990-2014. Two coders independently assessed eligibility and extracted data, and assessed study quality. Results were summarised qualitatively into social and economic, and healthcare-, therapy-, condition- and patient-related factors. The 51 studies included mainly examined patient-related factors and found consistent links between adherence and stronger inhaler-necessity beliefs, and possibly older age. There was limited evidence on the relevance of other determinants, partly due to study heterogeneity regarding the types of determinants examined. Methodological quality varied considerably and studies performed generally poorly on their definitions of variables and measures, risk of bias, sample size and data analysis. A broader adoption of common methodological standards and health behaviour theories is needed before cumulative science on the determinants of adherence to asthma inhalers among adults can develop further.

Impact of patients' judgment skills on asthma self-management: a pilot study

Background

The majority of current health literacy tools assess functional skills including reading, writing, and numeracy. Although these tools have been able to underline the impact of such skills on individuals’ health behaviour, there is a need for comprehensive measures to examine more advanced skills. The individual’s ability to use health-related information considering his/her own health context, and judging positive and negative consequences of their decisions has been conceptualized as judgment skills. The present study used a newly developed judgment skills tool to explore asthma self-management practices.

Design and methods

Eighty asthma patients were recruited from medical offices during the year 2013. The questionnaire was self-administered and contained health literacy questions, the judgment skill tool, the Asthma Control Test, and several self-management questions.

Results

Sixty-nine percent of participants had adequate health literacy, while 24% and 5% had marginal and inadequate levels, respectively. The high-judgment group referred more to their doctor when experiencing asthma problems t(76)=–2.18, P<0.032; complied more with the use of their control medicine t(77)=–3.24, P<0.002 and went more regularly to the doctor t(78)=–1.80, P<0.038 (one-tailed) than the low-judgment group.

Conclusions

The judgment skills tool can help identify asthma patients’ health information use and reveal how this use may affect some self-management practices.

[Deliberate interruptions and changes of dose of inhaled corticosteroids by asthma patients: "a community pharmacy study"]

BACKGROUND

Adherence to inhaled corticosteroids (ICS) remains a major issue for asthma management, even among patients receiving a regular prescription from their doctor. The frequency of deliberate interruption of ICS, and of spontaneous changes of dose, were studied in a population of asthma patients recruited in community pharmacies.

METHODS

Asthma patients (aged 18-50) recruited in community pharmacies reported in self-administered questionnaires their spontaneous interruptions and changes of doses of ICS during the past 3 months. The characteristics of patients who interrupted their therapy or who modified the dose were compared with other patients.

RESULTS

The studied population included 252 patients (mean age 35 year-old, females: 59%), of whom 62% had inadequately controlled asthma. Among these patients, 25% had interrupted ICS therapy during the past 3 months, while 21% spontaneously changed the dose. The most reported reason for interrupting ICS was the cessation of symptoms (50%). In multivariate analysis, interrupting ICS was mainly associated with inadequate asthma control (OR=3.1, 95% CI 1.5-6.4), while the strongest association with changing ICS doses was the patients' perception of asthma as a concern in their lives (OR=3.2, 95% CI 1.2-8.4).

CONCLUSION

These results underline a poor understanding of the purpose of ICS therapy by patients. They also highlight the need of therapeutic education to improve the management of the disease.

Impact of adherence to treatment with fluticasone propionate/salmeterol in asthma patients

OBJECTIVE

Low adherence with asthma treatment may be associated with suboptimal outcomes and hence create a treatment gap in the real-life setting. The objective of this study was to assess the long-term association between adherence to treatment with fixed-dose fluticasone propionate/salmeterol (FSC) and the risk of exacerbations and health care utilization in patients with asthma.

RESEARCH DESIGN AND METHODS

Observational single cohort study utilizing the Quebec Health Insurance databases. All patients (age >12 years) with a diagnosis of asthma (ICD9-CM 493.xx) between 2001 and 2010 were entered into the study cohort at the time of their first prescription for FSC at any dose. Follow-up continued to the last known claim or death. Adherence to treatment was ascertained as compliance (medication possession ratio ≥80%) and persistence (absence of treatment gap ≥30 days).

MAIN OUTCOME MEASURES

Outcomes assessed were exacerbations defined as one of the following: use of oral corticosteroid (OCS), emergency room (ER) visit for asthma or hospitalization for asthma. Asthma related health care resource utilizations ascertained were number of prescription claims for rescue medications, ER visits, hospitalizations, intensive care unit (ICU) stay, intubations, and general practitioner (GP) and respirologist visits.

RESULTS

A total of 19,126 patients were included in the study. The proportion of compliant and persistent patients were 42.7% and 29.3% respectively. Multivariate logistic regression analyses showed a significantly reduced adjusted odds of exacerbations for compliant (OR = 0.48; 95% CI: 0.44-0.54) and persistent patients (OR = 0.42; 95% CI: 0.38-0.48). Similarly, significantly lower rates of health care utilization were observed for compliant and persistent patients.

CONCLUSIONS

The results of this large population-based study have shown that increased adherence to treatment with FSC is associated with lower risk for exacerbations, lower rescue medication use and lower health care utilization in asthma patients. Despite the typical limitations of an administrative database study including validity of the diagnosis, the fact that compliance and persistence are calculated based on filled claims which does not guarantee that the patients actually took their medications, and the absence of clinical and laboratory data, the findings have implications for physician and patient awareness of the importance of adherence in the management of asthma.

Relationship between medication beliefs, self-reported and refill adherence, and symptoms in patients with asthma using inhaled corticosteroids

BACKGROUND

Beliefs play a crucial role in medication adherence. Interestingly, the relationship between beliefs and adherence varies when different adherence measures are used. How adherence, in turn, is related to asthma symptoms is still unclear. Our aim was to investigate the relationship between beliefs (ie, necessities and concerns) about inhaled corticosteroids (ICS) and subjectively as well as objectively measure adherence and the agreement between these measures. Further, the relationship between adherence and asthma symptoms was examined.

METHODS

A total of 280 patients aged 18-80 years who filled at least two ICS prescriptions in the preceding year were recruited to complete a questionnaire. The questionnaire included the Beliefs about Medicines Questionnaire to assess necessity beliefs and concerns about ICS, four questions about ICS use to measure self-reported adherence, and the Asthma Control Questionnaire to assess asthma symptoms. Proportion of days covered was used to determine pharmacy refill adherence.

RESULTS

Data from 93 patients with asthma were analyzed. Necessities were positively related to self-reported adherence (P = 0.01). No other associations were found between beliefs and subjective or objective adherence. There was no correlation between self-reported and refill adherence. Participants were significantly (P < 0.001) less adherent according to self-report data (24.4%) than according to pharmacy data (57.8%). No relationship was found between adherence and asthma symptoms.

CONCLUSION

Higher necessities are associated with higher self-reported adherence, suggesting that it could be more important to focus on necessities than on concerns in an attempt to improve adherence. Self-reported and refill adherence measurements cannot be used interchangeably. No relationship between adherence and asthma symptoms was found.

Efficacy of brief motivational interviewing to improve adherence to inhaled corticosteroids among adult asthmatics: results from a randomized controlled pilot feasibility trial

PURPOSE

Daily adherence to inhaled corticosteroid (ICS) regimens is one of the most important factors linked to achieving optimal asthma control. Motivational interviewing (MI) is a client-centered communication style that focuses on enhancing intrinsic motivation to engage in appropriate self-management behaviors. MI has been shown to improve a variety of health behaviors including medication adherence in other disorders, but its efficacy for the improvement of ICS adherence in asthmatics has yet to be examined. This pilot "proof of concept" trial assessed the feasibility of MI to improve daily ICS adherence and asthma control levels in adult asthmatics.

METHODS

Fifty-four poorly controlled (Asthma Control Questionnaire [ACQ] score ≥1.5), highly nonadherent (filled <50% of ICS medication in the last year) adult asthmatics were recruited from the outpatient asthma clinic of a university-affiliated hospital. Participants underwent baseline assessments and were randomly assigned to MI (3×30 minutes sessions within a 6-week period, n=26) or a usual care (UC) control group (n=28). ICS adherence (% pharmacy refills) and asthma control (ACQ, Asthma Control Test [ACT]) were measured at 6 and 12 months postintervention. Mixed model repeated measure analyses for both intent-to-treat and per-protocol were used. Results were adjusted for a priori-defined covariates including baseline adherence. Patients in the MI group also reported their impressions of the intervention.

RESULTS

Six-month adjusted intent-to-treat analyses revealed a mean change in the percentage of ICS refills of 13% in the MI group vs 6% in the UC group (between group net improvement associated with MI =+6% [-12% to 24%]). Twelve-month analyses revealed a mean change in the percentage of ICS refills of 11% (MI group) vs 7% in the UC group (between group net improvement associated with MI =+3% [-11% to 18%]) representing an effect size (ES) of d=0.20 (medium). Six-month adjusted net improvement in ACQ and ACT scores between MI and control groups was -0.2 and +0.7, respectively, with improvements being even more pronounced at 12 months (ACQ =-0.5; ACT =+1.1; ES, d=0.12 and 0.18 [small], respectively). Interestingly, 6- and 12-month net improvements in asthma self-efficacy (which is specifically targeted by MI) improved by +0.4 and +0.4, respectively, with an ES of d=0.46 (marginally large). Patients in the MI group rated the intervention overwhelmingly positively in terms of usefulness, pertinence, feasibility, enjoyableness, and likelihood to change adherence behavior.

CONCLUSION

Results suggest that a brief (90 minutes) MI intervention that targets ICS adherence can produce clinically significant improvements in adherence behavior, asthma control levels, and asthma self-efficacy in poorly controlled nonadherent asthmatics at 6 months that are maintained for 1 year, and it is well accepted by patients. Future studies including larger sample sizes, modified intervention designs (eg, MI "booster" sessions), and assessments of the extent behavior changes translate into clinical improvements (eg, in asthma control and quality of life) are warranted.

Using communication skills to improve adherence in children with chronic disease: the adherence equation

Nonadherence to maintenance medication is common in paediatric chronic conditions. Despite the common belief that nonadherence is therapy-resistant, and the apparent lack of evidence for successful interventions to improve adherence, there is, in fact, a considerable body of evidence suggesting that adherence can be improved by applying specific communicative consultation skills. These can be summarized as the adherence equation: adherence=follow-up+dialogue+barriers and beliefs+empathy and education => concordance. Close follow-up of children with a chronic condition is needed to establish a therapeutic partnership with the family. Teaching self management skills is not a unidirectional process of providing information, but requires a constructive and collaborative dialogue between the medical team and the family. Identifying barriers to adherence can be achieved in a non-confrontational manner, by showing a genuine interest what the patient's views and preferences are. In particular, parental illness perceptions and medication beliefs should be identified, because they are strong drivers of nonadherence. Through empathic evidence-based education, such perceptions and beliefs can be modified. By applying these strategies, concordance between the child's family and the medical team can be achieved, resulting in optimal adherence to the jointly created treatment plan.

A personality and gender perspective on adherence and health-related quality of life in people with asthma and/or allergic rhinitis

PURPOSE

Poor adherence to medication treatment for asthma and allergic rhinitis could challenge a positive health outcome. Health-related quality of life (HRQL) is an important measure of health outcome. Both personality and gender could influence adherence and perceptions of HRQL. The purpose was to clarify the role of personality and gender in relation to adherence and HRQL in people with asthma and/or rhinitis.

DATA SOURCES

Participants (n = 180) with asthma and allergic rhinitis, selected from a population-based study, filled out questionnaires on the five-factor model personality traits--neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness--HRQL, and adherence to medication treatment. Data were statistically analyzed using t-tests, Mann-Whitney tests, bivariate correlations, and multiple regressions.

CONCLUSIONS

Personality traits were associated with adherence to medication treatment in men. The influence of personality traits on HRQL also differed between men and women. These differences suggest that both a personality and gender perspective should be considered when planning care support aimed at improving adherence and HRQL in people living with asthma and/or allergic rhinitis.

IMPLICATIONS FOR PRACTICE

It is suggested that both a personality and gender perspective be taken into account in care support aimed at improving adherence and HRQL in people with asthma and allergic rhinitis.

Prescription fill patterns in underserved children with asthma receiving subspecialty care

BACKGROUND

Children with asthma receiving specialty care have been found to have improved asthma outcomes. However, these outcomes can be adversely affected by poor adherence with controller medications.

OBJECTIVE

To analyze pharmacy fill patterns as a measure of primary adherence in a group of underserved minority children receiving allergy subspecialty care.

METHODS

As part of a larger 18-month nebulizer use study in underserved children (ages 2-8 years) with persistent asthma, 53 children were recruited from an urban allergy practice. Pharmacy records were compared with prescribing records for all asthma medications.

RESULTS

Allergist controller prescriptions were written in 30-day quantities with refills and short-acting β-agonists (SABAs) with no refills. Only 49.1% of inhaled corticosteroid (ICS), 49.5% of combination ICS and long-acting β-agonist, and 64.5% of leukotriene modifier (LTM) initial and refill prescriptions were ever filled during the 18-month period. A mean of 5.1 refills (range, 0-14) for SABAs were obtained during 18 months, although only 1.28 SABA prescriptions were prescribed by the allergist. Mean times between first asthma prescription and actual filling were 30 days (range, 0-177 days) for ICSs, 26.6 days (range, 0-156 days) for LTMs, and 16.8 days (range, 0-139 days) for SABAs.

CONCLUSION

Underserved children with asthma receiving allergy subspecialty care suboptimally filled controller prescriptions, yet filled abundant rescue medications from other prescribers. Limiting albuterol prescriptions to one canister without additional refills may provide an opportunity to monitor fill rates of both rescue and controller medications and provide education to patients about appropriate use of medications to improve adherence.

Visual analog scale as a predictor of GINA-defined asthma control. The SACRA study in Japan

OBJECTIVE

The assessment of asthma control is pivotal to treatment decisions. A questionnaire that assesses the Global Initiative for Asthma (GINA)-defined control requires four questions. A visual analog scale (VAS) to evaluate asthma control can be simply marked, but its correlation with GINA-defined control has been insufficiently evaluated. The purpose of this study is to evaluate whether VAS levels can predict GINA-defined asthma control with particular emphasis on the distinctions between "partly controlled" and "uncontrolled" and between "partly controlled" and "controlled" asthma,

METHODS

A cross-sectional multicenter study was carried out throughout Japan (SACRA) from March to August 2009 among patients with a diagnosis and treatment of asthma. Asthma control was studied using the GINA questionnaire and a VAS measurement of asthma severity. Pulmonary function testing was not carried out,

RESULTS

1910 physicians enrolled 29,518 patients with asthma. 15,051 (51.0%) questionnaires were administered by physicians; patients filled out 14,076 (47.7%) questionnaires themselves. 28,225 (95.6%) of the patients were evaluable. VAS measurement of asthma symptoms was useful in predicting levels of GINA-defined control categories (the area under the receiver operating characteristic curve ranging from 0.704 to 0.837). Patients with "controlled," "partly controlled," and "uncontrolled" asthma were discriminated by VAS levels (1.50, 4.79, and 7.19). Similar results have been obtained with self- and physician-administered questionnaires showing the validity of results.

CONCLUSION

Measurement of VAS levels is able to discriminate between patients with "controlled," "partly controlled," and "uncontrolled" asthma. The VAS score could be a simple guide in clinical situations requiring daily or regular evaluation of asthma control.

Personality and reasons for not using asthma medication in young adults

OBJECTIVES

To identify young adults' stated reasons for not taking asthma medication and to determine the significance of personality, asthma control and health-related quality of life in relation to these stated reasons.

BACKGROUND

Reasons for non-adherence to asthma medication treatment have previously been studied, but research on the significance of personality in relation to stated reasons for not taking asthma medication is limited.

METHODS

Young adults with asthma (age 22 years; n = 216) stated their most common reasons for not taking asthma medication and completed postal questionnaires on personality, asthma control and health-related quality of life (HRQL).

RESULTS

The most common reason for non-adherence was "No perceived need" (n = 141). Participants giving this reason for not taking asthma medication scored lower on the personality trait Negative Affectivity and reported both higher asthma control and higher mental HRQL. "Insufficient routines" was the second most common reason (n = 66), and participants stating it scored higher on Negative Affectivity and reported lower asthma control. An increase in asthma control increased the odds of stating "No perceived need" as the reason for not taking asthma medication. An increase in Negative Affectivity was associated with an increase in the odds of giving "Insufficient routines" as a reason.

CONCLUSIONS

The personality trait Negative Affectivity and perceived asthma control played a role in the young adults' stated reasons for not taking asthma medication, which indicates that these parameters are of importance to young adults' medication management.

A review of mometasone furoate / formoterol in the treatment of asthma

INTRODUCTION

Asthma is a common chronic respiratory disease affecting the airways causing inflammation, airway hyperreactivity (AHR), and respiratory symptoms. Frequently, asthma can be effectively treated with inhaled corticosteroids (ICS) but in more severe cases additional drugs are required, such as long-acting β2-agonists (LABA). Mometasone furoate (MF) is a synthetic steroid exhibiting a strong affinity for the glucocorticoid receptor as well as a low bioavailability and a high plasma protein binding. In most cases, MF only requires once daily administration. Formoterol fumarate (F) is a full β2-agonist with a rapid onset and 12 h of duration.

AREAS COVERED

The present paper reviews the current knowledge of the novel combination of MF and F for the treatment of asthma. Furthermore, a description of the individual components is included.

EXPERT OPINION

At present, only few clinical studies of MF/F are available for review and more studies of MF/F efficacy are needed, especially comparative studies on other ICS/LABA drugs. However, it does not appear from the reviewed literature that MF/F or its individual components are inferior to other equivalent treatments.

Recent educational interventions for improvement of asthma medication adherence

Poor adherence to asthma medication treatment is a dilemma as it decreases the chance of achieving and maintaining a proper asthma control. Another dilemma is that there seems to be a small range of functional interventions that enhance adherence to long-term medication treatments. The aim was to review the last five years of published educational interventions for improving adherence to asthma medication. Through systematic database searches 20 articles were identified, which matched the inclusion criteria and described educational interventions to improve asthma self-management including adherence. The current review showed that addressing unintentional non-adherence in terms of incorrect inhaler technique by recurrent education improved the technique among many patients, but not among all. Phoning patients, as a means to remove medication beliefs as adherence barriers, seemed to be an effective educational strategy, shown as increased adherence. Involving patients in treatment decisions and individualising or tailoring educational support also seemed to have favourable effect on adherence. To conclude, addressing specific adherence barriers such as poor inhaler technique or medication beliefs could favour adherence. To change adherence behavior, the current review proposes that educational adherence support should be a collaborative effort between the patient and the health-care professional based on each individual patient's needs and patient factors, including elements such as personality traits.

Inhaled corticosteroids should be the first line of treatment for children with asthma

Although montelukast is claimed to be preferable to inhaled corticosteroids in children with asthma and allergic rhinitis, virus-induced exacerbations, exercise induced asthma, and in those experiencing difficulties with inhalation therapy, there is no scientific evidence to support any of these claims. In comparative trials and systematic reviews, inhaled corticosteroids are clearly more effective than montelukast in reducing asthma exacerbations, improving lung function, symptom scores, and rescue medication use. The effects on exercise induced bronchoconstriction appear to be similar. Because of their superior efficacy and excellent long-term efficacy and safety profile, inhaled corticosteroids are the treatment of first choice for the maintenance therapy of childhood asthma, irrespective of age or clinical phenotype.

Motivational foci and asthma medication tactics directed towards a functional day

BACKGROUND

There appears to be an obvious gap between a medical and patient adherence perspective. Deviating from a medication prescription could be regarded as fairly irrational, but with respect to patients' goals and/or concerns it could be seen as understandable. Thus, the aim was to elucidate adherence reasoning in relation to asthma medication.

METHODS

This was a qualitative study; data collection and analysis procedures were conducted according to Grounded Theory methodology. Eighteen persons, aged 22 with asthma and regular asthma medication treatment, were interviewed.

RESULTS

The emerged theoretical model illustrated that adherence to asthma medication was motivated by three foci, all directed towards a desired outcome in terms of a functional day as desired by the patient. A promotive focus was associated with the ambition to achieve a positive asthma outcome by being adherent either to the received prescription or to a self-adjusted dosage. A preventive focus was intended to ensure avoidance of a negative asthma outcome either by sticking to the prescription or by preventively overusing the medication. A permissive focus was associated with unstructured adherence behaviour in which medication intake was primarily triggered by asthma symptoms.

CONCLUSIONS

As all participants had consciously adopted functioning medication tactics that directed them towards the desired goal of a functional day. In an effort to bridge the gap between a patient- and a medical adherence perspective, patients need support in defining their desired functionality and guidance in developing a person-based medication tactic.

Illness perceptions: impact on self-management and control in asthma

PURPOSE OF REVIEW

Outcome in asthma is determined not only by pulmonary function or other biomedical characteristics. An important determinant of asthma outcome is illness perceptions: patients' subjective beliefs and emotional responses to their illness. Illness perceptions influence patients' coping and self-management behavior, and thereby outcome.

RECENT FINDINGS

We review recent studies on associations between illness perceptions and outcome in patients with asthma, with a range of respondents and caregivers, with varying degree of asthma severity, and in different settings of medical care. Most studies pertain to substantial numbers of patients, and have been performed in different countries, adding to the external validity of the findings. All studies report substantial effects of illness perceptions on various categories of outcome: illness perceptions reflecting personal control over the illness are associated with a positive outcome, that is, asthma control. Findings point at the importance and clinical relevance of addressing patients' illness perceptions, and suggest that this may improve outcome in asthma care. Well conducted intervention studies on this topic are called for in order to improve outcomes and quality of life in asthma patients.

SUMMARY

Illness perceptions influence the way in which patients with asthma cope and their self-management of the illness. Illness perceptions can be assessed quite easily and directly, they inform healthcare providers about the psychosocial responses of patients towards their asthma, they are responsive to change in the clinical encounter or via self-management intervention training. Exploring patient's illness perceptions, therefore, is a crucial component of good clinical care.
