Development and validation of the Patient Asthma Concerns Tool (PACT) to identify the needs of older people with asthma

Expert consensus recommendations for the management of asthma in older adults

Asthma is a public health problem in patients of any age, although there is still a tendency to erroneously assume that it is almost always confined to children and young people. Epidemiological studies indicate that, from the sixth decade of life, the prevalence of this disease in countries such as Spain reaches 6-10%, with a higher prevalence among women aged 64 to 75 years. In addition, two-thirds of asthma deaths occur at this stage of life, resulting in a substantial number of hospital admissions, longer hospital stays and, from a finance point of view, significant direct economic costs. Asthma in older adults (65 years or older) is now a matter of great concern, the reality of which is underestimated and undertreated. It is therefore essential to establish appropriate recommendations for the diagnosis and treatment of asthma in the aging population. This consensus, which brings together the latest evidence available, was conceived with this objective. The proposed recommendations/conclusions are the result of a nominal consensus developed throughout 2019 and validated by panellists in successive rounds of voting.

Airway diseases and health literacy (HL) measurement tools: A systematic review to inform respiratory research and practice

OBJECTIVE

To identify and evaluate asthma/COPD measurement tools that assess any of the five health literacy (HL) domains: (1) access, (2) understand, (3) evaluate, (4) communicate, and (5) use, as well as numeracy.

METHODS

MEDLINE/Embase (via Ovid) databases from 1974 to 2016 were searched and complimented by grey literature. Study selection and data extraction were conducted by two reviewers independently.

RESULTS

We identified 65 tools including 40 asthma, 22 COPD, and 3 asthma/COPD focused tools. Thirty tools had been validated and two assessed all five domains. The 'understand' domain was captured in 49 tools, followed by 'access' in 29 tools, 'use' in 24 tools, 'evaluate' in 20 tools, and 'communicate' in 10 tools. Two tools assessed 'numeracy'. Tool content comprised disease physiology, triggers, symptoms, inhaler technique, self-management practices, and rehab programs.

CONCLUSIONS

This review highlights paucity of HL tools that have been validated and/or assess the 'communicate' domain and makes a valuable contribution to filling an existing research gap in the field of HL by determining the deficiencies of such tools.

PRACTICE IMPLICATIONS

Our review uncovers which HL domains are under-measured, justifying the need to develop an airways HL measurement tool which applies the 5-domain model for asthma/COPD management.

Enabling and hindering factors influencing adherence to asthma treatment among adolescents: A systematic literature review

OBJECTIVES

The aim of this systematic literature review is to study the enabling and hindering factors influencing adherence to asthma treatment among adolescents. Furthermore, it explores the role of caregivers and the healthcare provider in terms of supporting adolescents to manage and live with asthma.

DATA SOURCES

The literature review was conducted using the MeSH terms asthma, adherence, health literacy, behavior, adolescents, tools, healthcare provider, caregiver, peer influence, self-management, quality of life, morbidity and mortality in PubMed, PsycInfo, MEDLINE and CINAHL.

STUDY SELECTION

The literature search resulted in 652 articles of which 304 were screened based on title and abstracts. Ninety-one of the screened articles were then selected for full-text assessment resulting in 42 articles for in-depth analysis.

RESULTS

The literature review identified nine enabling and hindering factors relevant for adherence to asthma treatment among adolescents: behavior, belief, self-management, health literacy, role of health provider, assessment of adherence, role of caregiver, role of peers and the national asthma guidelines.

CONCLUSION

Working with this particular age group is complex and further research in understanding adolescent's behavior, motives, beliefs and perceptions towards adherence to asthma treatment is required to guide them towards better self-management and acceptance of their condition.

The Asthma Control Questionnaire as a clinical trial endpoint: past experience and recommendations for future use

The goal of asthma treatment is to control the disease according to guidelines issued by bodies such as the Global Initiative for Asthma. Effective control is dependent upon evaluation of symptoms, initiation of appropriate treatment and minimization of the progressive adverse effects of the disease and its therapies. Although individual outcome measures have been shown to correlate with asthma control, composite endpoints are preferred to enable more accurate and robust monitoring of the health of the individual patient. A number of validated instruments are utilized to capture these component endpoints; however, there is no consensus on the optimal instrument for use in clinical trials. The Asthma Control Questionnaire (ACQ) has been shown to be a valid, reliable instrument that allows accurate and reproducible assessment of asthma control that compares favourably with other commonly used instruments. This analysis provides a summary of the use of ACQ in phase II, III and IV asthma trials. Comparisons between the ACQ and other instruments are also presented. Our analysis suggests that the ACQ is a valid and robust measure for use as a primary or secondary endpoint in future clinical trials.

Educational intervention for older people with asthma: a randomised controlled trial

OBJECTIVES

To improve the asthma control and adherence to asthma preventer medication of older people using the Patient Asthma Concerns Tool (PACT) to identify and address unmet needs and patient concerns.

METHODS

Community dwelling adults over 55 years, living in Victoria or New South Wales were recruited into a single-blind, parallel design, randomised-controlled trial comparing person-centred education including device technique, versus written information-only education. Fifty-eight participants randomised to the intervention group and 56 to the control completed participation.

OUTCOME MEASURES

asthma control, adherence to preventer medication, asthma related quality of life, asthma exacerbations and written action plan ownership were assessed at baseline, and 3 and 12 months post intervention.

RESULTS

Intervention participants experienced improvements in asthma control, adherence to asthma preventer medication, reduced exacerbations, improved quality of life and an increase in asthma action plan ownership at 3 and 12 months.

CONCLUSION

Asthma outcomes in older people can be significantly improved by delivering tailored education that identifies specific patient concerns and unmet needs.

PRACTICAL IMPLICATIONS

Use of the PACT to identify patient concerns and unmet needs will assist health professionals to improve the health literacy of patients by addressing gaps in their knowledge and perceptions of asthma control.
