Culture-specific programs for children and adults from minority groups who have asthma

An integrated operational definition and conceptual model of asthma self-management in teens

OBJECTIVES

A previous definition of adolescent asthma self-management was derived from interviews with clinicians/researchers and published literature; however, it did not incorporate perspectives of teens or parents. Therefore, we conducted in-depth interviews with teens and parents and synthesized present findings with the prior analysis to develop a more encompassing definition and model.

METHODS

Focal concepts were qualitatively extracted from 14-day self-management voice-diaries (n = 14) and 1-hour interviews (n = 42) with teens and parents (28 individuals) along with concepts found in the previous clinical/research oriented analysis. Conceptual structure and relationships were identified and key findings synthesized to develop a revised definition and model of adolescent asthma self-management.

RESULTS

There were two primary self-management constructs: processes of self-management and tasks of self-management. Self-management was defined as the iterative process of assessing, deciding, and responding to specific situations in order to achieve personally important outcomes. Clinically relevant asthma self-management tasks included monitoring asthma, managing active issues through pharmacologic and non-pharmacologic strategies, preventing future issues, and communicating with others as needed. Self-management processes were reciprocally influenced by intrapersonal factors (both cognitive and physical), interpersonal factors (family, social and physical environments), and personally relevant asthma and non-asthma outcomes.

CONCLUSION

This is the first definition of asthma self-management incorporating teen, parent, clinician, and researcher perspectives, which suggests that self-management processes and behaviors are influenced by individually variable personal and interpersonal factors, and are driven by personally important outcomes. Clinicians and researchers should investigate teens' symptom perceptions, medication beliefs, current approaches to symptom management, relevant outcomes, and personal priorities.

Changes in asthma self-management knowledge in inner city adolescents following developmentally sensitive self-management training

OBJECTIVE

To evaluate efficacy of a developmentally sensitive curriculum for improving asthma self-management knowledge, attitude, and self-efficacy in adolescents.

METHODS

Fourty-two inner-city adolescents (ages 16-20) participated in a 12hour asthma self-management training program. Self-management knowledge, attitude toward asthma, and asthma-related self-efficacy were measured using short-answer tests before and after training. T-Tests were used to evaluate impact and effect sizes were calculated.

RESULTS

Mean pretest knowledge was 21.37/46 points; mean posttest was 36.33/46 points. Change from pre- to posttest was highly significant (t=10.34; p<0.0001), with a large effect size (d=1.68). Females improved more than males (18.66±8.58 vs. 12.29±8.13, p=0.039). Greatest effects were seen in awareness of long-term consequences of uncontrolled asthma (d=2.04), ability to recognize symptoms of life-threatening asthma (d=1.61), correctly monitor symptoms (d=1.49), and tell if asthma was uncontrolled (d=1.39). Asthma self-efficacy also improved significantly (p=0.017), particularly confidence in ability to correctly manage asthma, however improvements in attitude did not achieve statistical significance.

CONCLUSION

Developmentally appropriate training is effective in increasing critical self-management knowledge and self-efficacy in inner city adolescents, particularly females.

PRACTICE IMPLICATIONS

Providers should screen carefully for symptoms and educate using developmentally appropriate training materials on ways to correctly monitor and manage symptom.

Interventions to enhance the adoption of asthma self-management behaviour in the South Asian and African American population: a systematic review

South Asian and other minority communities suffer poorer asthma outcomes, have a higher rate of unscheduled care and benefit less from most existing self-management interventions when compared to the majority population. Possible reasons for these differences include failure to implement asthma self-management strategies, or that strategies implemented were inappropriate for their needs; alternatively, they may relate to the minority and/or lower socioeconomic status of these populations. We aimed to synthesise evidence from randomised controlled trials for asthma self-management in South Asian and Black populations from different sociocultural contexts, and identify barriers and facilitators to implementing self-management. We systematically searched eight electronic databases, and research registers, and manually searched relevant journals and reference lists of reviews. Seventeen trials met the inclusion criteria and were analysed narratively. We found two culturally targeted interventions compared to fifteen culturally modified interventions. Interventions used diverse self-management strategies; education formed a central component. Interventions in South Asian and African-American minority communities were less effective than interventions delivered in indigenous populations in South Asia, though the latter trials were at higher risk of bias. Education, with continuous professional support, was common to most interventions. Facilitators to asthma self-management included: ensuring culturally/linguistically appropriate education, adapting to learning styles, addressing daily stressors/social support and generic self-management strategies. In conclusion, when developing and evaluating self-management interventions aimed at different cultures, the influence of sociocultural contexts (including whether patients are from a minority or indigenous population) can be important for the conceptualisation of culture and customisation of self-management strategies.

Culture-specific programs for children and adults from minority groups who have asthma

BACKGROUND

People with asthma who come from minority groups often have poorer asthma outcomes, including more acute asthma-related doctor visits for flare-ups. Various programmes used to educate and empower people with asthma have previously been shown to improve certain asthma outcomes (e.g. adherence outcomes, asthma knowledge scores in children and parents, and cost-effectiveness). Models of care for chronic diseases in minority groups usually include a focus of the cultural context of the individual, and not just the symptoms of the disease. Therefore, questions about whether tailoring asthma education programmes that are culturally specific for people from minority groups are effective at improving asthma-related outcomes, that are feasible and cost-effective need to be answered.

OBJECTIVES

To determine whether culture-specific asthma education programmes, in comparison to generic asthma education programmes or usual care, improve asthma-related outcomes in children and adults with asthma who belong to minority groups.

SEARCH METHODS

We searched the Cochrane Register of Controlled Trials (CENTRAL), the Cochrane Airways Group Specialised Register, MEDLINE, Embase, review articles and reference lists of relevant articles. The latest search fully incorporated into the review was performed in June 2016.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing the use of culture-specific asthma education programmes with generic asthma education programmes, or usual care, in adults or children from minority groups with asthma.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected, extracted and assessed the data for inclusion. We contacted study authors for further information if required.

MAIN RESULTS

In this review update, an additional three studies and 220 participants were added. A total of seven RCTs (two in adults, four in children, one in both children and adults) with 837 participants (aged from one to 63 years) with asthma from ethnic minority groups were eligible for inclusion in this review. The methodological quality of studies ranged from very low to low. For our primary outcome (asthma exacerbations during follow-up), the quality of evidence was low for all outcomes. In adults, use of a culture-specific programme, compared to generic programmes or usual care did not significantly reduce the number of participants from two studies with 294 participants for: exacerbations with one or more exacerbations during follow-up (odds ratio (OR) 0.80, 95% confidence interval (CI) 0.50 to 1.26), hospitalisations over 12 months (OR 0.83, 95% CI 0.31 to 2.22) and exacerbations requiring oral corticosteroids (OR 0.97, 95% CI 0.55 to 1.73). However, use of a culture-specific programme, improved asthma quality of life scores in 280 adults from two studies (mean difference (MD) 0.26, 95% CI 0.17 to 0.36) (although the MD was less then the minimal important difference for the score). In children, use of a culture-specific programme was superior to generic programmes or usual care in reducing severe asthma exacerbations requiring hospitalisation in two studies with 305 children (rate ratio 0.48, 95% CI 0.24 to 0.95), asthma control in one study with 62 children and QoL in three studies with 213 children, but not for the number of exacerbations during follow-up (OR 1.55, 95% CI 0.66 to 3.66) or the number of exacerbations (MD 0.18, 95% CI -0.25 to 0.62) among 100 children from two studies.

AUTHORS' CONCLUSIONS

The available evidence showed that culture-specific education programmes for adults and children from minority groups are likely effective in improving asthma-related outcomes. This review was limited by few studies and evidence of very low to low quality. Not all asthma-related outcomes improved with culture-specific programs for both adults and children. Nevertheless, while modified culture-specific education programs are usually more time intensive, the findings of this review suggest using culture-specific asthma education programmes for children and adults from minority groups. However, more robust RCTs are needed to further strengthen the quality of evidence and determine the cost-effectiveness of culture-specific programs.

A patient advocate to facilitate access and improve communication, care, and outcomes in adults with moderate or severe asthma: Rationale, design, and methods of a randomized controlled trial

Few interventions to improve asthma outcomes have targeted low-income minority adults. Even fewer have focused on the real-world practice where care is delivered. We adapted a patient navigator, here called a Patient Advocate (PA), a term preferred by patients, to facilitate and maintain access to chronic care for adults with moderate or severe asthma and prevalent co-morbidities recruited from clinics serving low-income urban neighborhoods. We describe the planning, design, methodology (informed by patient and provider focus groups), baseline results, and challenges of an ongoing randomized controlled trial of 312 adults of a PA intervention implemented in a variety of practices. The PA coaches, models, and assists participants with preparations for a visit with the asthma clinician; attends the visit with permission of participant and provider; and confirms participants' understanding of what transpired at the visit. The PA facilitates scheduling, obtaining insurance coverage, overcoming patients' unique social and administrative barriers to carrying out medical advice and transfer of information between providers and patients. PA activities are individualized, take account of comorbidities, and are generalizable to other chronic diseases. PAs are recent college graduates interested in health-related careers, research experience, working with patients, and generally have the same race/ethnicity distribution as potential participants. We test whether the PA intervention, compared to usual care, is associated with improved and sustained asthma control and other asthma outcomes (prednisone bursts, ED visits, hospitalizations, quality of life, FEV1) relative to baseline. Mediators and moderators of the PA-asthma outcome relationship are examined along with the intervention's cost-effectiveness.

Cultural relevance in medication adherence interventions with underrepresented adults: systematic review and meta-analysis of outcomes

OBJECTIVE

This meta-analysis systematically compiles intervention research designed to increase medication adherence among underrepresented adults.

METHOD

Comprehensive searching located published and unpublished studies with medication adherence behavior outcomes. Studies were included if samples were adults living in North America who had any of the following backgrounds or identities: African American, Native American, Latino, Latino American, Asian, Asian American, Pacific Islander, Native Alaskan, or Native Hawaiian. Random-effect analyses synthesized data to calculate effect sizes as a standardized mean difference and variability measures. Exploratory moderator analyses examined the association between specific efforts to increase the cultural relevance of medication adherence studies and behavior outcomes.

RESULTS

Data were synthesized across 5559 subjects in 55 eligible samples. Interventions significantly improved medication adherence behavior of treatment subjects compared to control subjects (standardized mean difference=0.211). Primary studies infrequently reported strategies to enhance cultural relevance. Exploratory moderator analyses found no evidence that associated cultural relevance strategies with better medication adherence outcomes.

CONCLUSION

The modest magnitude of improvements in medication adherence behavior documents the need for further research with clear testing of cultural relevance features.

The use of a collaborative structured methodology for the development of a multifaceted intervention programme for the management of asthma (the MIA project), tailored to the needs of children and families of South Asian origin: a community-based, participatory study

Background

Asthma is one of the most common chronic childhood illnesses in the UK. South Asian children are more likely to suffer from their asthma and be admitted to hospital. While this inequality needs to be addressed, standard behaviour-change interventions are known to be less successful in minority ethnic groups. Evidence suggests a need to enhance services provided to ethnic minority communities by developing culturally sensitive tailored interventions.

Objectives

The Management and Interventions for Asthma (MIA) project aimed to test an iterative multiphase participatory approach to intervention development underpinned by the socioecological model of health, producing an intervention-planning framework and enhancing an evidence-based understanding of asthma management in South Asian and White British children.

Design

Interviews and focus groups facilitated by community facilitators (CFs) were used to explore knowledge and perceptions of asthma among South Asian communities, children, families and healthcare professionals (HCPs). A smaller comparison group of White British families was recruited to identify aspects of asthma management that could be addressed either by generic interventions or by a tailored approach. Collaborative workshops were held to develop an intervention planning framework and to prioritise an aspect of asthma management that would be used as an exemplar for the development of the tailored, multifaceted asthma intervention programme.

Setting

The community study was based in a largely urban environment in Leicester, UK.

Participants

Participants were recruited directly from the South Asian (Indian, Pakistani and Bangladeshi) and White British communities, and through the NHS. Children were aged between 4 and 12 years, with a range of asthma severity.

Intervention development

The study had four phases. Phase 1 consisted of an evidence review of barriers and facilitators to asthma management in South Asian children. Phase 2 explored lay understandings of childhood asthma and its management among South Asian community members (n = 63). Phase 3 explored perceptions and experiences of asthma management among South Asian (n = 82) and White British families (n = 31) and HCP perspectives (n = 37). Using a modified intervention mapping approach incorporating psychological theory, phase 4 developed an intervention planning framework addressing the whole asthma pathway leading to the development of an exemplar multifaceted, integrated intervention programme called ‘ACT [Awareness, Context (cultural and organisational) and Training] on Asthma’.

Results

Data on the social patterning of perceptions of asthma and a lack of alignment between the organisation of health services, and the priorities and competencies of British South Asian communities and families were produced. Eleven key problem areas along the asthma pathway were identified. A four-arm multifaceted tailored programme, ‘ACT on Asthma’, was developed, focusing on the theme ‘getting a diagnosis’. This theme was chosen following prioritisation by families during the collaborative workshops, demonstrating the participatory, iterative, phased approach used for the intervention design.

Conclusions

The MIA study demonstrated barriers to optimal asthma management in children at the family, provider and healthcare system levels and across the whole asthma pathway. Interventions need to address each of these levels to be effective. Minority ethnic communities can be successfully engaged in collaborative intervention development with a community-focused and culturally sensitive methodology.

Future work

Further research is required to (1) assess the feasibility and effectiveness of the proposed ‘ACT on Asthma’ programme, (2) develop methods to increase active participation of children in research and service development, (3) develop and test strategies to enhance public understanding of asthma in South Asian communities and (4) identify effective means of engaging the wider family in optimising asthma management.

A systematic review of explanatory factors of barriers and facilitators to improving asthma management in South Asian children

BACKGROUND

South Asian children with asthma are less likely to receive prescriptions and more likely to suffer uncontrolled symptoms and acute asthma admissions compared with White British children. Understanding barriers are therefore vital in addressing health inequalities. We undertook a systematic review identifying explanatory factors for barriers and facilitators to asthma management in South Asian children. South Asians were defined as individuals of Indian, Pakistani or Bangladeshi descent.

METHODS

Data Sources - Medline, HMIC, EMBASE, ASSIA, Web of Science, BNI, CINAHL, PsycINFO, OpenSIGLE, CRD, Scopus, NHS Evidence, Cochrane Library, Campbell Collaboration, RCPCH, ATS, ERS, Asthma UK, Google Scholar & Asthma Guidelines (BTS, GINA, ATS, Monash, NAEPP, Singapore & New Zealand) to August 2013.Inclusion Criteria - Qualitative, quantitative or mixed methods research with primary focus on identifying explanations for barriers and/or facilitators to asthma management in South Asian children aged 0-18 years with diagnosed/suspected asthma and/or carers and/or healthcare professionals.Data Extraction - Three authors independently reviewed, selected & extracted eligible articles with disagreements resolved by research team discussion.

RESULTS

15 studies encompassing 25,755 children, 18,483 parents/carers and 239 healthcare professionals were included. Barriers and explanatory factors identified were:1. Lack of asthma knowledge in families and healthcare professionals.2. Under-use of preventer medications.3. Non-acceptance/denial of asthma.4. Over-reliance on Emergency Department management.5. Communication problems.6. Non-adherence to medication.7. Use of complementary therapies.Little facilitators regarding asthma management were identified.

CONCLUSIONS

Several key issues were identified as likely to be ethnic-specific to South Asian families, rather than a reflection of minority status: impact of parental and professional knowledge and beliefs, health service utilisation pattern explanations and the impact of prejudice and stigmatisation. Other explanations such as language barriers are not strictly ethnic specific but instead reflect a minority position.Further research is required to identify why barriers exist, the mechanisms by which they impact on asthma management and how they can be overcome. Furthermore, understanding the difference between barriers and explanations that are ethnic-specific and those that are related to being a minority will enable the application of generic system-wide interventions where ethnicity is not the issue and ethnically-tailored interventions where needed.

Complementary and alternative medicine use and adherence to asthma medications among Latino and non-Latino white families

OBJECTIVE

The current study sought to evaluate patterns of complementary and alternative medicine (CAM) use in a sample of Latino and non-Latino white (NLW) children with asthma to determine whether parental beliefs about conventional medications and barriers to obtaining these medications were related to CAM use and to assess whether CAM use was associated with decreased adherence to controller medications.

METHODS

Participants included 574 families of children with asthma from NLW, Puerto Rican (PR), and Dominican backgrounds from Rhode Island (RI) and from Island PR. All parents completed a brief checklist of barriers to medication use and an assessment of CAM approaches. A subsample of 259 families had controller medication use monitored objectively for approximately 1 month by MDILog (fluticasone propionate), TrackCap (montelukast), or dosage counter (fluticasone/salmeterol combination).

RESULTS

Prevalence of CAM use was high among Latino families. Perceived barriers to obtaining medication were related to increased CAM use in PR families from RI. Elevated medication concerns were positively associated with CAM use among NLW and Island PR families. CAM use was positively related to objective adherence within NLW families, and unrelated in other groups.

CONCLUSIONS

CAM use is common among Latino families with asthma. Among some families, CAM use may be initiated as a way to cope with barriers to obtaining medication or when parents have concerns about conventional medications. Families who report CAM use do not appear to be substituting CAM for conventional asthma medication.

Targeted interventions for improved equity in maternal and child health in low- and middle-income settings: a systematic review and meta-analysis

BACKGROUND

Targeted interventions to improve maternal and child health is suggested as a feasible and sometimes even necessary strategy to reduce inequity. The objective of this systematic review was to gather the evidence of the effectiveness of targeted interventions to improve equity in MDG 4 and 5 outcomes.

METHODS AND FINDINGS

We identified primary studies in all languages by searching nine health and social databases, including grey literature and dissertations. Studies evaluating the effect of an intervention tailored to address a structural determinant of inequity in maternal and child health were included. Thus general interventions targeting disadvantaged populations were excluded. Outcome measures were limited to indicators proposed for Millennium Development Goals 4 and 5. We identified 18 articles, whereof 15 evaluated various incentive programs, two evaluated a targeted policy intervention, and only one study evaluated an intervention addressing a cultural custom. Meta-analyses of the effectiveness of incentives programs showed a pooled effect size of RR 1.66 (95% CI 1.43-1.93) for antenatal care attendance (four studies with 2,476 participants) and RR 2.37 (95% CI 1.38-4.07) for health facility delivery (five studies with 25,625 participants). Meta-analyses were not performed for any of the other outcomes due to scarcity of studies.

CONCLUSIONS

The targeted interventions aiming to improve maternal and child health are mainly limited to addressing economic disparities through various incentive schemes like conditional cash transfers and voucher schemes. This is a feasible strategy to reduce inequity based on income. More innovative action-oriented research is needed to speed up progress in maternal and child survival among the most disadvantaged populations through interventions targeting the underlying structural determinants of inequity.

Indigenous healthcare worker involvement for Indigenous adults and children with asthma

BACKGROUND

Asthma education is regarded as an important step in the management of asthma in national guidelines. Racial, ethnicity and socio-economic factors are associated with markers of asthma severity, including recurrent acute presentations to emergency health facilities. Worldwide, indigenous groups are disproportionately represented in the severe end of the asthma spectrum. Appropriate models of care are important in the successful delivery of services, and are likely contributors to improved outcomes for people with asthma.

OBJECTIVES

To determine whether involvement of an indigenous healthcare worker (IHW) in comparison to absence of an IHW in asthma education programs, improves asthma related outcomes in indigenous children and adults with asthma.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Airways Group Specialised Register, MEDLINE and EMBASE databases, review articles and reference lists of relevant articles. The latest search was in January 2010.

SELECTION CRITERIA

All randomised controlled trials comparing involvement of an indigenous healthcare worker (IHW) in comparison to absence of an IHW in asthma education programs for indigenous people with asthma.

DATA COLLECTION AND ANALYSIS

Two independent review authors selected data for inclusion, a single author extracted the data. Both review authors independently assessed study quality. We contacted authors for further information. As it was not possible to analyse data as "intention-to-treat", we analysed data as "treatment received".

MAIN RESULTS

Two studies fulfilled inclusion criteria involving 133 children randomised to an asthma education programme involving an IHW, compared to a similar education programme without an IHW. One study was not strictly Indigenous. 110 of these children completed the trials. Children's asthma knowledge score was significantly better in the group that had IHW education compared with control (mean difference 3.30; 95% CI 1.07 to 5.53), parents' asthma knowledge score (standardised mean difference (SMD) 1.23; 95% CI 0.59 to 1.87), parents' asthma skill score (SMD 0.67; 95% CI 0.28 to 1.06) and days absent from school (100% school-aged children in the intervention group missed <7 days, 21% of controls missed 7-14 days, difference = 21%, 95%CI 5-36%). There was no significant difference in mean number of exacerbations (per year) between groups. There was no difference in quality of life or children's asthma skill score; both were limited to one study only and the direction favoured IHW group. There were no studies in adults.

AUTHORS' CONCLUSIONS

The involvement of IHW in asthma programs targeted for their own ethnic group in 2 small trials was beneficial in improving most, but not all asthma outcomes in children with asthma. It is very likely that involvement of an IHW is beneficial. However as exacerbation frequency was not significantly different between groups, we cannot be confident of the results in all settings. Nevertheless, given the complexity of health outcomes and culture as well as the importance of self-determination for indigenous peoples, the practice of including IHW in asthma education programs for indigenous children and adults with asthma is justified, but should be subject to further randomised controlled trials.
