A review of barriers to effective asthma management in Puerto Ricans: cultural, healthcare system and pharmacogenomic issues

Understanding Native Hawaiian Caregivers' Beliefs About Pediatric Asthma Management

Native Hawaiian health beliefs and cultural practices may influence how Native Hawaiian caregivers manage their children's asthma. Understanding the use of cultural practices as an asthma management strategy among Native Hawaiian caregivers who have a child with mild persistent, moderate persistent, or severe persistent asthma may inform the development of effective culturally-based asthma management interventions. A qualitative descriptive methodology with medical anthropology framework was used to describe pediatric asthma management strategies, define cultural asthma management practices, and identify cultural practices caregivers were aware of but did not use. Eighteen face-to-face interviews with self-identified Native Hawaiian caregivers of school-aged children between 5 and 12 years with asthma were interviewed. The study found that Native Hawaiian caregivers across all asthma severity types believed that the perceived cause of asthma was hereditary and environmental exposure. Also, standard asthma management strategies were used by caregivers with an emphasis on preventing exposure to known asthma triggers. If asthma symptoms presented themselves, Native Hawaiian caregivers often managed them with alternative practices before using the prescribed medication. Alternative practices included the use of massage and exposure to salt air. Native Hawaiian caregivers readily discussed awareness of cultural practices. However, cultural practices such as lā'au lapa'au (herbal medicine) and lomilomi (massage) were seldom, if ever, used. The study provides healthcare providers with knowledge regarding Native Hawaiian caregivers and their beliefs about the perceived cause of asthma and strategies for managing asthma, including use and awareness of cultural practices.

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.

Improved quality-of-life of caregivers of children with asthma through guideline-based management

OBJECTIVE

The quality of life (QOL) of caregivers of children with asthma may be related to children's responses to asthma management.

AIM

To evaluate change in QOL over time of caregivers of children with asthma through guideline-based management.

DESIGN

This was a 3-year prospective cohort study of children with asthma referred to our pediatric asthma center. Families completed Pediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ), the Asthma Control Test™ (ACT), and reported the number of days/month of albuterol use and wheezing at each clinic visit.

RESULTS

We enrolled 143 children, ages 7-17 years (mean = 10.6 ± 2.9), 56.6% male, 70.6% Caucasian. Patients were managed by the same MD (n = 65,45.5%) or APN (n = 78,54.5%) over time. The mean total PACQLQ significantly increased over the 3-year period (F = 67.418, p < .001). Total scores at the first visit were 4.8 ± 1.6, which improved to 6.1 ± 1 at the 3-month follow-up visit. This improvement was sustained at the 1, 2, and 3-year clinic visits. PACQLQ emotional function (F = 60.798, p < .001) and activity limitation (F = 41.517, p < .001) domains significantly improved as well. PACQLQ scores were significantly associated with improved ACT scores (r = .37 to .47, p < .05), fewer days/month of albuterol use (r = -.25 to -.36., p < .05), and wheezing (r = -.28 to -.33, p < .05). There were no significant differences in PACQLQ, or asthma clinical outcome measures between MD and APN providers.

CONCLUSION

Use of National Asthma Education and Prevention Program (NAEPP) guidelines significantly improved QOL of caregivers of children with asthma and in asthma-related symptoms. Improvements over time were independent of type of providers.

Pediatric Asthma Care Coordination in Underserved Communities: A Quasiexperimental Study

OBJECTIVES

To assess the effect of care coordination on asthma outcomes among children in underserved urban communities.

METHODS

We enrolled children, most of whom had very poorly or not well-controlled asthma, in medical-social care coordination programs in Los Angeles, California; Chicago, Illinois; Philadelphia, Pennsylvania; and San Juan, Puerto Rico in 2011 to 2014. Participants (n = 805; mean age = 7 years) were 60% male, 50% African American, and 42% Latino. We assessed asthma symptoms and health care utilization via parent interview at baseline and 12 months. To prevent overestimation of intervention effects, we constructed a comparison group using bootstrap resampling of matched control cases from previous pediatric asthma trials.

RESULTS

At follow-up, intervention participants had 2.2 fewer symptom days per month (SD = 0.3; P < .01) and 1.9 fewer symptom nights per month (SD = 0.35; P < .01) than did the comparison group. The relative risk in the past year associated with the intervention was 0.63 (95% confidence interval [CI] = 0.45, 0.89) for an emergency department visit and 0.69 (95% CI = 0.47, 1.01) for hospitalization.

CONCLUSIONS

Care coordination may improve pediatric asthma symptom control and reduce emergency department visits.

POLICY IMPLICATIONS

Expanding third-party reimbursement for care coordination services may help reduce pediatric asthma disparities.

How can adherence to asthma medication be enhanced? Triangulation of key asthma stakeholders' perspectives

BACKGROUND AND OBJECTIVES

Adherence to daily asthma controller medication has been shown to be the most effective component of asthma self-management; however, patient's adherence to asthma medication remains poor. This study aimed to understand how patients' long-term asthma controller medication adherence may be improved and facilitated by comparing key asthma stakeholders' perspectives.

METHOD

Six focus group interviews including 38 asthma stakeholders (n = 13 patients, n = 13 pulmonologist physicians, and n = 12 allied healthcare professionals) were conducted. Interviews were qualitatively analysed.

RESULTS

Although similar themes were brought up across different asthma stakeholders, the way in which they were framed differed across stakeholders. The most salient discussion revolved around the content and the moment in which asthma education should be approached to facilitate patients' adherence to asthma medication.

CONCLUSION

Asthma medication adherence is a complex process and successful interventions aimed at its improvement would benefit from: (a) making an effort to understand patients' experiences and negotiate the treatment regimen, rather than imposing recommendations; (b) considering treatment as a shared responsibility involving the patient, the healthcare professional(s), and the patients' social networks; and,

The Hispanic pharmacist: Value beyond a common language

Objective:

To highlight the added value of bilingual Hispanic pharmacists in the care of Hispanic patients by sharing their patients’ language and culture.

Summary:

Inability to speak and/or write in the patients’ native language severely impairs our best efforts to deliver good health care. This is a widely recognized cause of non-compliance or less than favorable possible health outcomes in Hispanic patients. What has received less attention, however, is that the ability to speak Spanish alone may not remove completely the barrier for non-compliance among Hispanics. Bilingual Spanish–English pharmacists do not have the language barrier, but if they do not recognize and accept cultural differences, their impact in their patients’ response may still be limited.

Conclusion:

It is time to recognize the added value of Hispanic pharmacists to Hispanic patients’ health outcomes. Understanding and sharing a culture allows the pharmacist to make medication education and interventions relevant to the patient and spark interest in their own health care. Thus, in caring for the health of our patients, cultural barriers may be more challenging to conquer than language barriers; deep appreciation and acceptance of our patients’ belief system cannot be acquired by just reading about it, having a computerized program, or hiring an interpreter.

Latino caregiver experiences with asthma health communication

In this article, we analyze qualitative data from a purposeful sample of limited English proficiency (LEP) asthma health caregivers. We used ethnically concordant, semistructured, in-depth Spanish-language interviews and a follow-up focus group to explore issues related to communication during pediatric asthma encounters in medical settings. Inductive coding of Spanish transcripts by a bilingual research team was performed until thematic saturation was reached. Several key findings emerged. LEP caregivers encountered significant asthma burdens related to emotional stress, observed physical changes, and communication barriers. Language-discordant communication and the use of ad hoc interpreters were common. This finding is complex, and was influenced by perceptions of interpreter availability, delays in care, feelings of mistrust toward others, and individual emotional responses. Language-concordant education and suitable action plans were valued and desired. We discuss a revealing depiction of the LEP caregiver experience with asthma health communication and recommend areas for further inquiry.

Findings from a community-based asthma education fair for Latino caregivers

OBJECTIVE

To assess limited English proficiency (LEP) asthma caregiver quality of life (QoL), skills retention and healthcare utilization after an asthma education fair (AEF).

METHODS

A language concordant AEF was conducted at a Latino community center. LEP caregivers of children 1-12 years old and an established asthma diagnosis participated in three skill stations: (a) medication recognition and administration, (b) peak flow use (if child ≥ 5 years) and (c) action plan dissemination. Spacers, peak flow meters and individualized action plans were distributed. A validated, pediatric asthma caregiver quality of life questionnaire (PACQLQ-Spanish version) was administered. Baseline data was compared to follow-up interview data at three and six months after the AEF. Mean PACQLQ scores were analyzed with Wilcoxon signed-rank test and nominal paired data with McNemar's test.

RESULTS

We analyzed data from 18 caregivers able to speak English well (22%), not well (28%) or not at all (50%). After three months, improved caregiver QoL was experienced (51 vs. 72, p<0.01). No differences were observed in medication recognition, spacer and peak flow use or peak flow interpretation. After six months, mean school days missed due to asthma decreased (4.1 vs. 0.4, p<0.01). Mean clinic visits, emergency department visits and hospitalizations remained unchanged.

CONCLUSIONS

Implementation of a community-based AEF with action plan administration can be beneficial for LEP caregivers and their children. QoL improvements to emotional wellbeing and activity limitations were observed, and lower rates of school absenteeism were reported. Caregiver ability to accurately identify medications was not enhanced.
