Association of caregiver health beliefs and parenting stress with medication adherence in preschoolers with asthma

Objective: This study examined the associations of parenting stress and caregiver negative health beliefs with medication adherence in a sample of preschool-aged children with asthma.

Methods: Participants included 43 caregivers and their child with asthma, aged 2–5?years, who were prescribed a preventative or controller medication. Assessment included parent report of parenting stress associated with parental characteristics and difficult child behavior, health-related beliefs, and adherence to inhaled corticosteroids (ICS). Pharmacy refill records were reviewed to measure medication adherence objectively. Statistical analyses included paired samples t-test and Pearson’s correlation coefficients.

Results: Parent-report and objective measures of adherence to ICS were significantly different, with parents reporting significantly higher rates of medication adherence (p?p?Conclusions: Because the findings for parenting stress are not consistent with that of the literature on school-aged children with asthma, our results may suggest that preschool children are a unique developmental group. A review of endorsed health beliefs also highlights strengths and concerns for caregivers of these very young children. Overall, our study findings underscore the importance of caregivers’ health-related beliefs in promoting adherence to ICS in young children with asthma.     

Influence of Caregiver and Provider Communication on Symptom Days and Medication Use for Inner-City Children With Asthma

Background. Effective pediatric guideline-based asthma care requires the caregiver to accurately relay the child's symptom frequency, pattern of rescue and controller medication use, and level of asthma control to the child's primary care clinician. Objective. This study evaluated the longitudinal effects of a caregiver-clinician asthma communication education intervention (ACE) relative to an asthma education control group (CON) on symptom days and controller medication use in inner-city children with asthma. Participants and Methods. 231 inner-city children with asthma, recruited from urban pediatric emergency departments (EDs) and community practices, were followed for 12 months. Data included number of symptom days and nights, ED visits, hospitalizations, presence of limited activity, and controller medication use over 12 months. Pharmacy records were used to calculate controller to total asthma medication ratios as a proxy of appropriate controller medication use. Multivariate logistic regression models were used to identify factors associated with number of symptom days and nights over the past 30 days at the 12-month follow-up. Results. Most caregivers rated the communication with their child's clinician as high. Unadjusted and adjusted rates of symptom days and nights did not differ by group at follow-up. ACE children trended towards a higher controller to total medication ratio at 12 months as compared to CON children (mean ratio: ACE: 0.54, SD 0.3; CON, 0.45, SD 0.4; p = .07). Activity limitation due to asthma and persistent asthma severity were the only factors significantly associated with reporting any symptom day within the past 30 days, adjusting for treatment group, number of oral corticosteroid courses and number of clinician visits in the last 6 months, seasonality, insurance type, and controller to total asthma medication ratio covariates. Conclusion. A home-based caregiver asthma communication educational intervention was not associated with decreased symptom days. However, a trend was noted in higher controller to total medication ratios in the intervention group. Inner-city caregivers of children with asthma may require a health systems approach to help convey the child's asthma health information to their clinician.     

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, (c) taking into account different stakeholders' concerns, needs, perspectives, and knowledge.     

Controller adherence following hospital discharge in high risk children: A pilot randomized trial of text message reminders

Objective: To assess the feasibility of a mobile health, inhaled corticosteroid (ICS) adherence reminder intervention and to characterize adherence trajectories immediately following severe asthma exacerbation in high-risk urban children with persistent asthma. Methods: Children aged 2–13 with persistent asthma were enrolled in this pilot randomized controlled trial during an asthma emergency department (ED) visit or hospitalization. Intervention arm participants received daily text message reminders for 30 days, and both arms received electronic sensors to measure ICS use. Primary outcomes were feasibility of sensor use and text message acceptability. Secondary outcomes included adherence to prescribed ICS regimen and 30-day adherence trajectories. Group-based trajectory modeling was used to examine adherence trajectories. Results: Forty-one participants (mean age 5.9) were randomized to intervention (n = 21) or control (n = 20). Overall, 85% were Black, 88% had public insurance, and 51% of the caregivers had a high school education or less. Thirty-two participant families (78%) transmitted medication adherence data; of caregivers who completed the acceptability survey, 25 (96%) chose to receive daily reminders beyond that study interval. Secondary outcome analyses demonstrated similar average daily adherence between groups (intervention = 36%; control = 32%, P = 0.73). Three adherence trajectories were identified with none ever exceeding 80% adherence. Conclusions: Within a high-risk pediatric cohort, electronic monitoring of ICS use and adherence reminders delivered via text message were feasible for most participants, but there was no signal of effect. Adherence trajectories following severe exacerbation were suboptimal, demonstrating an important opportunity for asthma care improvement.     

Asthma control and obesity in urban African American children

Objective: To examine the relationship between body mass index (BMI), gender, age, controller medication use, household smoke exposure, season, and allergic rhinitis status with asthma control in a group of lower income, African American children. We hypothesized that non-obese children would have better asthma control. Methods: Baseline data from a longitudinal study of children in a school-based asthma program in a Midwest urban area were analyzed. 360 children, ages 4–15 years, who were enrolled in either the 2012–2013 or 2013–2014 program were included. Asthma control was classified using criteria from the 2007 National Asthma Education and Prevention Program. Multiple ordinal regression was performed. Results: The median age was 9 years, 61% had well-controlled asthma, and 29% were obese. The model included all main effects plus two interaction terms and was significant (χ²(7) = 22.17, p =.002). Females who were normal weight (OR, 2.78; 95% CI, 1.38–5.60, p =.004) or overweight (OR, 3.12; 95% CI, 1.26–7.72, p =.014) had better asthma control than obese females. For males, there were no differences by BMI category but males without allergic rhinitis had significantly better asthma control (OR, 2.23; 95% CI, 1.25–3.97, p =.006) than those with allergic rhinitis. Conclusions: Non-obese girls and non-allergic males had better asthma control. Promotion of healthy activity and nutrition as well as management of allergic rhinitis should be part of the asthma plan in school-based programs in low income urban areas. Innovative approaches to address asthma care in low income populations are essential.     

Misunderstanding of Asthma Controller Medications: Association with Nonadherence

Objective.?Nonadherence to regular inhaled anti-inflammatory medication use is a frequent contributor to poor control of persistent asthma and may result from misunderstanding of the preventive role of such medications. This study's aims are to 1) test the hypothesis that misunderstanding is associated with decreased adherence to its daily use and 2) identify factors associated with increased risk of misunderstanding. Study Design.?A sample of parents of children with asthma insured by Medicaid and enrolled in managed care programs in Northern California, Washington, and Massachusetts were interviewed by telephone. This analysis focused on the subset that reported having an inhaled anti-inflammatory medication and whose medication use and symptom frequency in the 2 weeks before the interview suggested persistent asthma. Misunderstanding of the role of inhaled anti-inflammatory medication was defined as identifying it as being for treatment of symptoms after they begin and not for prevention of symptoms before they start. Results.?A total of 1663 parents of children with asthma (63% response rate) were interviewed. Of those, 571 subjects (34%) reported use of an inhaled anti-inflammatory medication and met our criteria for persistent asthma. Among those with persistent asthma, 23% (131 parents) misunderstood the role of their child's inhaled anti-inflammatory. Misunderstanding of inhaled anti-inflammatory medication was associated with decreased adherence to its daily use (odds ratio [OR] 0.18, 95% confidence interval [CI], 0.11–0.29). The risk for misunderstanding was lower if the patient had seen a specialist (OR 0.42, 95% CI, 0.24–0.75) or had graduated high school (OR = 0.54, 95% CI, 0.34–0.84). Conclusion.?Misunderstanding of the role of inhaled anti-inflammatory medication is associated with reduced adherence to its daily use.     

Pharmacy Fill Patterns in Young Urban Children with Persistent Asthma

Background. Medication adherence impacts healthcare utilization. Pharmacy records are useful to establish fill patterns. Objective. Use pharmacy records to establish medication patterns fill patterns for comparison to healthcare utilization. Methods. Pharmacy records of 175 children with persistent asthma were collected and compared to healthcare utilization. Results. Majority of subjects had significant healthcare utilization, low numbers of rescue medications, and poor controller medication fill rates. Those with more rescue medications had more healthcare utilization and more controller medications. Conclusions. Pharmacy fill patterns demonstrate few rescue and/or controller medication fills. Those with more rescue medications reported increased healthcare utilization despite controller medications.     

School nurse asthma program reduces healthcare utilization in children with persistent asthma

Objective: We examined the impact of a novel, school nurse-supervised asthma therapy program on healthcare utilization. Methods: We retrospectively reviewed charts of 84 children enrolled in this program in central Massachusetts between 2012 and 2015. Physicians identified children with persistent asthma and poor medication adherence. These children were enrolled in the program to receive daily-inhaled corticosteroid at school, supervised by their school nurse, with ongoing communication between physician's office and school nurse through the school year. This program relied on established family, provider and school resources rather than research staff. The primary outcome was change in the number of emergency department (ED) visits in the year before and after enrollment. Secondary outcomes were hospital admissions, school absences, and rescue medication use. Results: The study population was on average 10.5 years old, 63% male, 67% Hispanic, 19% black, 14% white with 95% using Medicaid insurance. Asthma-related ED visits over a 1-year period decreased 37.5%, from a pre-intervention mean of 0.8 visits to a post-intervention mean of 0.3 visits (p < 0.001). Asthma-related hospital admissions decreased from a pre-intervention mean of 0.3 admissions to post-intervention mean of 0 admissions (p < 0.001). Asthma rescue medication refills decreased by 46.3% from the pre- to post-intervention period (p = <.001). There were also non-significant declines in school absences and oral steroid use for children enrolled. Conclusions: We demonstrate a significant reduction in healthcare utilization for children enrolled in this unique school nurse-supervised asthma program, which utilizes a clinical-school partnership to deliver preventative asthma medication to school-aged children under sustainable conditions.     

Combining pharmacy expertise with asthma educator certification: assessing the impact on inner-city asthma patients

Objective: Asthma is one of the major causes of hospital readmissions in the South Bronx. The goal of this study was to assess the impact of asthma education provided by registered pharmacists with asthma educator certification (AE-C), on medication adherence and hospitalizations/Emergency Department (ED) visits. Methods: This was a retrospective chart review of patients seen in the pulmonary clinic from October 2014 to August 2015 for asthma education by AE-C pharmacists. Medical records were reviewed over an 18-month period – 9?months before and after the initial asthma education session. Data obtained included adherence to asthma controller inhalers based on pharmacy refill claims, asthma control using asthma control test (ACT) scores and asthma-related hospitalizations or ED visits within 30?days of asthma education. Pre-education data served as the pre-intervention group data and post-education data served as the post-intervention group data, allowing each patient to serve as their own control. Results: We found a statistically significant improvement in average medication adherence, i.e. asthma controller inhaler fills at pharmacy (46.3% vs 67.9%, p-value <0.001) and asthma control (15.71% vs 56.38%, p-value <0.001) between the pre-intervention and the post-intervention groups. Additionally, a lower hospitalization/ED utilization rate (31.2% vs 6.38%, p-value <0.001) was observed in the post-intervention group within 30?days of education. Conclusions: Asthma education provided by AE-C pharmacists had a positive impact on asthma care in our inner-city community. Improving medication adherence and asthma control as well as decreasing hospital utilization could potentially decrease health care costs in addition to improving quality of life.     

The Pediatric Asthma Control and Communication Instrument for the Emergency Department (PACCI-ED) improves physician assessment of asthma morbidity in pediatric emergency department patients

Objectives: To determine whether the Pediatric Asthma Control and Communication Instrument for the Emergency Department (PACCI-ED), a 12-item questionnaire, can help ED attendings accurately assess a patient’s asthma control and morbidity. Methods: This was a randomized-controlled trial performed at an urban pediatric ED of children aged 1–17 years presenting with an asthma exacerbation. Parents answered PACCI-ED questions about their children’s asthma. Attendings were randomized to view responses to the PACCI-ED (intervention group) or to be blinded to the completed PACCI-ED (control group). The two groups were compared on their empirical clinical assessment of: (1) chronic asthma control categories, (2) asthma trajectory (stable, worsening or improving), (3) patient adherence to controller medications, and (4) burden of disease for the patient’s family. The validated PACCI algorithm was used as the criterion standard for these four outcomes. Accuracy of clinical assessment was compared between intervention and control groups using chi-squared tests and an intention-to-treat approach. Results: Seventeen ED attendings were enrolled in the study and 77 children visits were included in the analysis. There were no significant differences between the intervention and the control groups for child’s gender, age, race, and asthma characteristics. Intervention group attendings were more accurate than control group attendings in assessing the category of chronic asthma control (43% versus 19%; p?=?0.03), disease trajectory (72% versus 45%; p?=?0.02), and the disease burden for families (74% versus 35%; p?=?0.001) over the past 12 months. There was a trend towards more accuracy of intervention versus control attendings for estimating patient adherence to controller medications (72% versus 48%; p?=?0.06). Conclusions: The PACCI-ED improves the assessment of asthma control, trajectory, and burden by ED attendings, and may help assessment of asthma medication adherence and prior asthma exacerbations. The PACCI-ED can be used to improve provider assessment of asthma morbidity during pediatric ED visits for asthma exacerbations, and to identify children who may benefit from interventions to reduce asthma morbidity.     

Family caregivers' reported nonadherence to the controller medication of asthma in children in Casablanca (Morocco): Extent and associated factors

Objective: Recent statistics show a relatively high prevalence of asthma among Moroccan children and a weak control over their symptoms. To our knowledge, no research has been carried out to document adherence to the controller treatment in this population. This study aims 1) to assess the extent of children's nonadherence to the controller treatment of asthma in an urban region of Morocco as reported by a family caregiver, and 2) to identify the associated factors. Methods: We conducted a cross-sectional study among caregivers of asthmatic children (2–12 years old) in different health and education facilities of Casablanca-Settat. We administered face-to-face questionnaires incorporating validated instruments (Medication Adherence Rating Scale-Asthma (MARS-A), Beliefs about Medicines Questionnaire (BMQ), Asthma Knowledge Questionnaire). Univariate and multivariate log-binomial regressions evaluating the association between several factors and reported nonadherence were performed (prevalence ratios (PR) and 95% confidence intervals (CI)). Results: Through two public hospitals, three private medical clinics, and one private school, 103 caregivers were recruited. Low adherence to the controller treatment of asthma was reported by 48% of the caregivers (MARS-A <45). In the multivariate model, caregivers with the lowest level of knowledge about asthma were almost three times more likely to report low adherence compared to caregivers with the highest level (PR = 2.93; 95% CI: 1.14–7.52). Conclusions: This study highlights the finding that low adherence is widespread in this context and also the importance of targeting caregivers' knowledge of asthma for interventions.     

The Patient's Perspective: Adherence or Non-adherence to Asthma Controller Therapy?

Study objective. Adherence with controller therapy poses a major challenge to the effective management of persistent asthma. The aim of this study was to explore the patient-related aspects of adherence among adult asthmatics. Design and participants. The participants (n = 509 adult asthmatics), recruited from all parts of Denmark, answered the questionnaire concerning asthma knowledge, attitudes, adherence, and treatment through the Internet. Results. A total of 67% of the patients were prescribed inhaled corticosteroids (ICS). However, according to Global Initiative for Asthma (GINA)-guidelines' symptom severity classification, 85% should have been on ICS. Accidental and intentional non-adherence with ICS at least twice a week was reported by 27% and 24%, respectively. In case of deterioration, 60% of the patients preferred to take more reliever medication, instead of increasing the ICS dose. Having a fixed daily routine with regard to medication and following the advice given by their doctor were the main reasons for adherence, whereas lack of perceived symptoms was the main reason for non-adherence. Non-adherence was associated with increasing disagreement with the statements that controller therapy is effective (p < 0.04), as well as an essential part of asthma therapy (p < 0.002). Conclusions. Both accidental and intentional non-adherence with controller therapy is common among adult asthmatics. The reasons for suboptimal adherence seem to be accessible through education of both patients and caregivers.     

Assessing health outcomes,quality of life,and healthcare use among school-age children with asthma

Objective: Asthma affects six million children in the United States. Most people can control their asthma symptoms with effective care, management, and appropriate medical treatment. Information on the relationship between asthma control and quality of life indicators and health care use among school-age children is limited. Methods: Using the 2006–2010 combined Behavior Risk Factor Surveillance System Asthma Call-back Survey child data, we examined asthma control and asthma attack status among school-age (aged 5–17 years) children with asthma from 35 states and the District of Columbia. Multivariable logistic regression models were used to assess if having uncontrolled asthma and having ≥1 asthma attacks affect quality of life (activity limitation and missed school days) and healthcare use (emergency department [ED] visits and hospitalizations). Results: About one-third (36.5%) of the 8,484 respondents with current asthma had uncontrolled asthma and 56.8% reported ≥1 asthma attack in the past year. Having uncontrolled asthma and having ≥1 asthma attack were significantly associated with activity limitation (aPR = 1.43 and 1.74, respectively), missed school (1.45 and 1.68), ED visits (2.05 and 4.78), and hospitalizations (2.38 and 3.64). Long-term control (LTC) medication use was higher among respondents with uncontrolled asthma (61.3%) than respondents with well-controlled asthma (33.5%). Conclusions: Having uncontrolled asthma is associated with reduced quality of life and increased health care use. However, only 61.3% of respondents with uncontrolled asthma use LTC medications. Increasing use of LTC medications among children with uncontrolled asthma could help improve quality of life and reduce health care use.     

Low-level environmental tobacco smoke exposure and inflammatory biomarkers in children with asthma

Objective: The effects of low-level environmental tobacco smoke (ETS) exposure, on asthma control, lung function and inflammatory biomarkers in children with asthma have not been well studied. The objective of the study was to assess ETS exposure in school-age children with asthma whose parents either deny smoking or only smoke outside the home, and to assess the impact of low-level ETS exposure on asthma control, spirometry and inflammatory biomarkers. Methods: Forty patients age 8–18 years with well-controlled, mild-to-moderate persistent asthma treated with either inhaled corticosteroids (ICS) or montelukast were enrolled. Subjects completed an age-appropriate Asthma Control Test and a smoke exposure questionnaire, and exhaled nitric oxide (FeNO), spirometry, urinary cotinine and leukotriene E₄ (LTE₄) were measured. ETS-exposed and unexposed groups were compared. Results: Only one parent reported smoking in the home, yet 28 (70%) subjects had urinary cotinine levels ≥1?ng/ml, suggesting ETS exposure. Seven subjects (18%) had FeNO levels >25parts per billion, six of whom were in the ETS-exposed group. In the ICS-treated subjects, but not in the montelukast-treated subjects, ETS exposure was associated with higher urinary LTE₄, p?=?0.04, but had no effect on asthma control, forced expiratory volume in 1?s or FeNO. Conclusions: A majority of school-age children with persistent asthma may be exposed to ETS, as measured by urinary cotinine, even if their parents insist they don’t smoke in the home. Urinary LTE₄ was higher in the ETS-exposed children treated with ICS, but not in children treated with montelukast.     

A primary care-based asthma program improves recognition and treatment of persistent asthma in inner-city children compared to routine care

Objective: To examine whether a primary care-based asthma program that applies the Expert Panel Report 3 (EPR-3): Guidelines for the Diagnosis and Management of Asthma-2007 criteria to classify asthma severity increases detection of persistent asthma in inner-city children and affects “step of care” compared to routine care. Methods: A retrospective chart review was conducted of 97 consecutive children referred to the asthma program from 2011–2013. Asthma severity documented during routine health care maintenance visits was compared to the asthma severity assessed during the asthma program visit using five standardized questions and spirometry. Medication plan “step of care” was compared pre- and post- the asthma program visit. Results: 79 children, ages 5–19 years old (mean = 9.6), had spirometry tracings meeting American Thoracic Society criteria and were included in this study. 53% were male. The majority of children were Latino (45.6%) or African American (35.4%). At the asthma program visit, more children were identified with moderate or severe persistent asthma based upon clinical questions (47.9%), spirometry (56.9%) or combined criteria (75.3%) than had been identified during routine care (15.2%); all p < .05. After the asthma program visit, more children were prescribed controller medications (82.3% vs 63.3%; p < .05) and 40.6% had their medication plan stepped up. Conclusions: In this population of inner-city children, asthma severity was under-recognized and undertreated during routine care. A primary care based asthma program, which formalized applying EPR-3 criteria, increased detection of persistent asthma and led to “step-ups” in treatment plans.
