Self-reported adherence, management behavior, and barriers to care after an emergency department visit by inner city children with asthma

Predictors of outpatient follow-up care after adult emergency department asthma visits and association with 30-day outcomes

Objective: Guidelines recommend outpatient follow-up after emergency department visits for asthma, but factors related to rates of follow-up among the adult population are understudied. We sought to describe patient and community-level predictors of outpatient follow-up after an index ED visit for asthma and evaluate the association between outpatient follow-up visits and subsequent ED revisits.Methods: We conducted a retrospective observational cohort study of adult patients with emergency departments visits for asthma. The primary predictor was time to outpatient follow-up visit within 30 days of the index ED visit. The primary outcome was all-cause ED revisit within 30 days of the index ED visit. Cox proportional hazards regression was utilized to test the association between time to outpatient follow-up and hazard of ED revisit within 30 days.Results: Time to outpatient follow-up visit within 30 days was not significantly associated with hazard of 30-day ED revisit for asthma (HR 1.05; 95% CI 0.69-1.61). However, male patients (HR 1.45; 95% C 1.11-1.89) and smokers (HR 1.67; 95% CI 1.22-2.29) were significantly more likely to have an ED revisit.Conclusion: Younger, Black patients with Medicaid were less likely to receive follow-up care relative to older patients insured by Medicare. While follow-up visits were not associated with 30-day revisit rates, differences by age, race, and insurance status suggest disproportionate barriers to accessing care. Future research may target these subgroups to improve transitions of care after an ED visit for asthma.

Inhaled corticosteroid prescriptions in the ED for recurrent asthma using IT clinical decision support: revisit after cessation of an incentive program

INTRODUCTION

The objective of this study was to assess whether inhaled corticosteroid (ICS) prescription rates for patients with poorly controlled asthma presenting to the emergency department (ED) remained high with a clinical support system in place, after a financial incentive program ended. This study is the second phase of a previous study done at our institution. The first phase demonstrated that the introduction of an electronic alert system advising providers to prescribe ICS to patients with poorly controlled asthma, along with a financial incentive, increased ICS prescription rates from 2% to 77%. Clinical support systems are necessary to improve control for patients with asthma, as prescribing ICS in the ED has not previously been standard of care.

METHODS

This retrospective study identified 96 eligible patients during the study period of January 1, 2019 to December 31, 2019. Subjects included patients aged 4-18 with at least two ED visits for asthma within 365 days and no recent ICS prescription. For subjects meeting these criteria, an electronic alert activated, advising the provider to prescribe ICS.

RESULTS

ICS prescription rate without the incentive remained high at 0.74 (0.59, 0.86) and was not significantly different than the rate with the incentive of 0.77 (0.65, 0.87), with p value 0.82. No significant differences were detected in baseline characteristics between patients discharged with and without an ICS prescription.

CONCLUSIONS

This study confirmed that an electronic alert advising ICS prescription in the ED for patients with recurrent asthma visits is effective, even without a financial incentive.

Race and Asthma Outcomes in Older Adults: Results from the National Asthma Survey

BACKGROUND

The number of older adults with asthma continues to rise, yet the effects of race and ethnicity on asthma outcomes in this population are unknown.

OBJECTIVE

To characterize the effect of race and ethnicity on asthma outcomes in a large national sample of older adults and to identify factors that are associated with disparities found.

METHODS

Data from the 2015 Behavioral Risk Factor Surveillance Survey and Asthma Call-Back Survey were analyzed. Respondents were included if they had a current asthma diagnosis, were aged ≥55, and self-identified as non-Hispanic white, African American, or Hispanic. Demographic variables, health care access, comorbidities, and asthma history were correlated with asthma outcomes (health care utilization and asthma control). Asthma outcome variables were further analyzed using multivariable logistic regression.

RESULTS

A total of 4700 individuals were included. Compared with non-Hispanic white respondents, African American and Hispanic respondents had lower incomes, greater impaired access to health care due to cost, and increased reliance on rescue medications. After controlling for factors including income, education, comorbidities, and health insurance, African American and Hispanic respondents were twice as likely to visit the emergency room (ER) for asthma (P < .001 for both) and 40% less likely to report uncontrolled daytime symptoms (P = .002 and .008).

CONCLUSIONS

Racial differences in asthma outcomes persist despite controlling for multiple social determinants of health and access to health insurance through Medicare. Minority patients were more likely to visit the ER but less likely to report frequent daytime symptoms. These findings indicate that comprehensive strategies to address assessment, monitoring, and treatment are needed to decrease health disparities.

Inhaled corticosteroids prescriptions increased in the ED for recurrent asthma exacerbations by automated electronic reminders in the ED

Objective: The objective of this study was to evaluate the impact of an electronic alert on the prescription rate of inhaled corticosteroids (ICS) by ED providers for poorly controlled persistent asthmatic children.Methods: Study subjects included asthmatic patients age 4-18 presenting to the ED at Phenix Children's Hospital between February 9, 2018 and December 4, 2018, with a history of at least two previous ED visits for acute exacerbation of asthma within 365 days, no active ICS prescription within 90 days, and free from developmental delay, bronchopulmonary dysplasia due to prematurity, cystic fibrosis, sickle cell disease, and/or interstitial ling disease. Patients meeting these criteria triggered an electronic alert prompting the medical provider to prescribe ICS or indicate reason for not prescribing. Instruction on the alert was provided to ED attending physicians and residents by email and through several educational sessions held prior to the implementation.Results: Among 62 patients without prior ICS who were discharged home from the ED, ICS was prescribed for 48 (77%). No statistically significant differences were detected in baseline characteristics between patients discharged home from the ED with and without ICS prescription. While ICS was prescribed by a larger proportion of physicians (56%) compared to residents (42%), statistical significance was not reached. For the 14 (33%) patients who were discharged home without ICS, no reason was provided to indicate why ICS were not prescribed.Conclusion: An electronic alert incorporated into the ED workflow to populate a discharge order set is effective to initiate asthma controller medication for poorly controlled pediatric patients. Additional data describing reasons for not prescribing ICS can further refine recommendations for ICS prescriptions, and provide a comprehensive strategy to support clinical decision for pediatric asthma control in acute care settings.

Discharge communication practices in pediatric emergency care: a systematic review and narrative synthesis

BACKGROUND

The majority of children receiving care in the emergency department (ED) are discharged home, making discharge communication a key component of quality emergency care. Parents must have the knowledge and skills to effectively manage their child's ongoing care at home. Parental fatigue and stress, health literacy, and the fragmented nature of communication in the ED setting may contribute to suboptimal parent comprehension of discharge instructions and inappropriate ED return visits. The aim of this study was to examine how and why discharge communication works in a pediatric ED context and develop recommendations for practice, policy, and research.

METHODS

We systematically reviewed the published and gray literature. We searched electronic databases CINAHL, Medline, and Embase up to July 2017. Policies guiding discharge communication were also sought from pediatric emergency networks in Canada, USA, Australia, and the UK. Eligible studies included children less than 19 years of age with a focus on discharge communication in the ED as the primary objective. Included studies were appraised using relevant Joanna Briggs Institute (JBI) checklists. Textual summaries, content analysis, and conceptual mapping assisted with exploring relationships within and between data. We implemented an integrated knowledge translation approach to strengthen the relevancy of our research questions and assist with summarizing our findings.

RESULTS

A total of 5095 studies were identified in the initial search, with 75 articles included in the final review. Included studies focused on a range of illness presentations and employed a variety of strategies to deliver discharge instructions. Education was the most common intervention and the majority of studies targeted parent knowledge or behavior. Few interventions attempted to change healthcare provider knowledge or behavior. Assessing barriers to implementation, identifying relevant ED contextual factors, and understanding provider and patient attitudes and beliefs about discharge communication were identified as important factors for improving discharge communication practice.

CONCLUSION

Existing literature examining discharge communication in pediatric emergency care varies widely. A theory-based approach to intervention design is needed to improve our understanding regarding discharge communication practice. Strengthening discharge communication in a pediatric emergency context presents a significant opportunity for improving parent comprehension and health outcomes for children.

Self-management behaviors in World Trade Center rescue and recovery workers with asthma

BACKGROUND

Asthma is a major source of morbidity among World Trade Center (WTC) rescue and recovery workers. While physical and mental health comorbidities have been associated with poor asthma control, the potential role and determinants of adherence to self-management behaviors (SMB) among WTC rescue and recovery workers is unknown.

OBJECTIVES

To identify modifiable determinants of adherence to asthma self-management behaviors in WTC rescue and recovery worker that could be potential targets for future interventions.

METHODS

We enrolled a cohort of 381 WTC rescue and recovery workers with asthma. Sociodemographic data and asthma history were collected during in-person interviews. Based on the framework of the Model of Self-regulation, we measured beliefs about asthma and controller medications. Outcomes included medication adherence, inhaler technique, use of action plans, and trigger avoidance.

RESULTS

Medication adherence, adequate inhaler technique, use of action plans, and trigger avoidance were reported by 44%, 78%, 83%, and 47% of participants, respectively. Adjusted analyses showed that WTC rescue and recovery workers who believe that they had asthma all the time (odds ratio [OR]: 2.37; 95% confidence interval [CI]: 1.38-4.08), that WTC-related asthma is more severe (OR: 1.73; 95% CI: 1.02-2.93), that medications are important (OR: 12.76; 95% CI: 5.51-29.53), and that present health depends on medications (OR: 2.39; 95% CI: 1.39-4.13) were more likely to be adherent to their asthma medications. Illness beliefs were also associated with higher adherence to other SMB.

CONCLUSIONS

Low adherence to SMB likely contributes to uncontrolled asthma in WTC rescue and recovery workers. Specific modifiable beliefs about asthma chronicity, the importance of controller medications, and the severity of WTC-related asthma are independent predictors of SMB in this population. Cognitive behavioral interventions targeting these beliefs may improve asthma self-management and outcomes in WTC rescue and recovery workers. Key message: This study identified modifiable beliefs associated with low adherence to self-management behaviors among World Trade Center rescue and recovery rescue and recovery workers with asthma which could be the target for future interventions.

CAPSULE SUMMARY

Improving World Trade Center-related asthma outcomes will require multifactorial approaches such as supporting adherence to controller medications and other self-management behaviors. This study identified several modifiable beliefs that may be the target of future efforts to support self-management in this patient population.

Medication adherence in pediatric asthma: A systematic review of the literature

OBJECTIVE

To provide a systematic review of correlates of adherence to inhaled corticosteroids (ICS) in pediatric asthma across the individual, family, community, and healthcare system domains.

METHODS

Articles assessing medication adherence in pediatric asthma published from 1997 to 2016 were identified using PsychINFO, Medline, and CINAHL. Search terms included asthma, compliance, self-management, adherence, child, and youth. Search results were limited to articles: 1) published in the US; 2) using a pediatric population (0-25 years old); and 3) presenting original data related to ICS adherence. Correlates of adherence were categorized according to the domains of the Pediatric Self-Management Model. Each article was evaluated for study quality.

RESULTS

Seventy-nine articles were included in the review. Family-level correlates were most commonly reported (N = 51) and included socioeconomic status, race/ethnicity, health behaviors, and asthma knowledge. Individual-level correlates were second-most common (N = 37), with age being the most frequently identified negative correlate of adherence. Health care system correlates (N = 24) included enhanced asthma care and patient-provider communication. Few studies (N = 10) examined community correlates of adherence. Overall study quality was moderate, with few quantitative articles (26.38%) and qualitative articles (21.4%) referencing a theoretical basis for their studies.

CONCLUSIONS

All Pediatric Self-Management Model domains were correlated with youth adherence, which suggests medication adherence is influenced across multiple systems; however, most studies assessed adherence correlates within a single domain. Future research is needed that cuts across multiple domains to advance understanding of determinants of adherence.

Asthma treatment and outcomes for children in the emergency department and hospital

OBJECTIVE

To describe and compare the treatment of acute asthma exacerbations in children given in the emergency department (ED) and admitted to acute care floor in the hospital or intensive care unit (ICU).

METHODS

A retrospective chart review of visits for acute exacerbation of asthma treated at Phoenix Children's Hospital between January 1, 2014 and December 31, 2016.

RESULTS

A total of 287 asthma exacerbation cases were identified including 106 (37%) ED visits, 134 (47%) hospital floor and 47 (16%) ICU admissions. A history of a previous ED visit (ED 88%, Floor 60% and ICU 68%; p < 0.0001) and prior pulmonology inpatient consultation (ED 30%, Floor 19% and ICU 15%; p = 0.05) varied significantly. Pulmonology inpatient consultations were performed more frequently in the ICU than on the hospital floor (54% versus 8%; p < 0.0001). Although overall 145 (51%) of the cases were already on inhaled corticosteroids (ICS) at the time of visit with no differences across locations, ICS initiation/step-up was greater in the ICU (72%) than on the hospital floor (54%) and ED (2%) (p < 0.0001). A recommendation given to the family for follow-up with pulmonology was more frequent for patients who had been admitted to the ICU (68%) as compared to those only admitted to the floor (31%) or ED (4%) (p < 0.0001). Readmission rates were similar for patients previously admitted to the hospital (Floor 42%; ICU 40%), but significantly higher for previous ED visits (77%) (p < 0.0001).

CONCLUSIONS

Physicians in the ED have an opportunity to provide preventative care in the acute care setting and should be encouraged to initiate treatment with ICS. Consideration should be given to develop a program or clinical pathway focused on long-term asthma management and maintenance to reduce readmissions and long hospital stays.

The Three-Herb Formula Shuang-Huang-Lian stabilizes mast cells through activation of mitochondrial calcium uniporter

Mast cells (MCs) are key effector cells of IgE-FcεRI- or MrgprX2-mediated signaling event. Shuang-Huang-Lian (SHL), a herbal formula from Chinese Pharmacopoeia, has been clinically used in type I hypersensitivity. Our previous study demonstrated that SHL exerted a non-negligible effect on MC stabilization. Herein, we sought to elucidate the molecular mechanisms of the prominent anti-allergic ability of SHL. MrgprX2- and IgE-FcεRI-mediated MC activation in vitro and in vivo models were developed by using compound 48/80 (C48/80) and shrimp tropomyosin (ST), respectively. Our data showed that SHL markedly dampened C48/80- or ST-induced MC degranulation in vitro and in vivo. Mechanistic study indicated that cytosolic Ca²⁺ (Ca²⁺_[c]) level decreased rapidly and sustainably after SHL treatment, and then returned to homeostasis when SHL was withdrawn. Moreover, SHL decreases Ca²⁺_[c] levels mainly through enhancing the mitochondrial Ca²⁺ (Ca²⁺_[m]) uptake. After genetically silencing or pharmacologic inhibiting mitochondrial calcium uniporter (MCU), the effect of SHL on the Ca²⁺_[c] level and MC degranulation was significantly weakened. Simultaneously, the activation of SHL on Ca²⁺_[m] uptake was completely lost. Collectively, by activating MCU, SHL decreases Ca²⁺_[c] level to stabilize MCs, thus exerting a remarkable anti-allergic activity, which could have considerable influences on clinical practice and research.

Primary Care Follow-up After Emergency Department Visits for Routine Complaints: What Primary Care Physicians Prefer and What Emergency Department Physicians Currently Recommend

OBJECTIVES

Given that the vast majority of pediatric patients that present to the emergency department (ED) are discharged home after their visit, one issue for study is the appropriate recommendations for follow-up after the ED visit. Numerous PubMed searches using various keywords revealed a gap in the literature regarding the desires of primary care physicians (PCPs) concerning follow-up after ED visits. This study was conducted to determine how pediatric emergency medicine (PEM) physicians' recommendations for follow-up align with the desires of (PCPs) for follow-up after ED visits.

METHODS

An electronic survey was distributed to pediatric emergency physicians at one community-based academic institution regarding current recommendations for follow-up with PCPs for 12 common diagnoses seen in the ED. A similar survey was sent to pediatricians in the same community inquiring about their desires for follow-up after their patients are seen in the ED for the same diagnoses.

RESULTS

Completion rates for the survey were 40/40 (100%) for PEM physicians and 78/145 (54%) for pediatricians. In 11/12 of the diagnoses included, PEM physicians recommended a statistically significant (P < 0.05) closer follow-up than desired by the PCPs.

CONCLUSIONS

Recommendations for follow-up made by PEM physicians and desired by PCPs vary significantly. Overall, PEM physicians recommend closer follow-up than desired by PCPs for low acuity complaints. Closing of this gap may allow for a better allocation of resources and consistency of care.

Outcomes of follow-up care after an emergency department visit among pediatric asthmatics in the military health system

BACKGROUND AND OBJECTIVES

Asthma exacerbations frequently trigger emergency department (ED) visits. Guidelines recommend timely follow-up after an ED visit for asthma, however, other studies have questioned the quality of follow-up care and their effect on subsequent ED utilization. We evaluated follow-up care on asthma outcomes in pediatric asthmatics enrolled in the Military Health System (MHS) after an ED visit for asthma.

METHODS

This retrospective study utilized MHS data to evaluate 2-17-year-old persistent asthmatics with an ED visit for asthma between 2010-2012. Demographics, medication dispensing, and subsequent asthma related ED and hospital utilization were compared between those with or without a 28-day follow-up appointment.

RESULTS

10,460 of 88,837 persistent asthmatics met inclusion criteria for an asthma ED visit. 4,964 (47.5%) had ≥ 1 follow-up visit. In the 29-365 days after their ED visit, 21.1% of the follow-up cohort required an ED re-visit compared to 24.0% of the patients without follow-up. Follow-up care was associated with a reduction in ED re-visits (adjusted hazard ratio 0.86; 95% confidence interval 0.79, 0.93). Controller medications were dispensed to 76.0% of the follow-up cohort within 90 days of their ED visit compared to 49.7% in the group without follow-up.

CONCLUSIONS

Despite universal access to healthcare, less than half of pediatric MHS asthma patients had follow-up within 28 days of an ED visit. Those with follow-up were more likely to fill a controller medication within 90 days post-ED visit, and less likely to have an asthma ED re-visit in the subsequent year.

Inner-city asthma: special considerations for management

PURPOSE OF REVIEW

Asthma is prevalent in inner-city populations, exhibiting significant morbidity and mortality. This review focuses on the consequential findings of recent literature, providing insight into onset of asthma, complicating factors, prediction of exacerbations, and novel treatment strategies.

RECENT FINDINGS

Analyses of environmental influence on inner-city children demonstrated novel interactions, implicating potentially protective benefits from early life exposures to pests and pets and isolating detrimental effects of air pollution on asthma morbidity. Through detailed characterization of inner-city asthmatics, predictors of seasonal exacerbations surfaced. Focused, season-specific treatment of inner-city asthmatics with omalizumab identified those most likely to benefit from season-tailored therapy. Comparative studies of urban and rural populations revealed that race and household income, rather than location of residence, impose the greatest risk for increased asthma prevalence and morbidity.

SUMMARY

Challenging previously conceived exposure-disease relationships, recent literature has elucidated new avenues in the complex interplay between immunologically active exposures and their effects on inner-city asthma. These findings, and improved understanding of other relevant exposures, could steer the direction of primary (and secondary) disease prevention research. Moreover, careful identification of asthma characteristics has effectively established predictors of exacerbations, highlighting individuals for which additional therapies are warranted and for whom such treatments are most likely to be effective.

LEAP: A randomized-controlled trial of a lay-educator inpatient asthma education program

OBJECTIVE

To evaluate the impact of LEAP, a volunteer-based, inpatient asthma education program for families of inner-city children with asthma.

METHODS

711 children ages 2-17 years admitted with status asthmaticus were randomized to receive usual care or usual care plus a supplemental education intervention. Both groups completed a baseline interview. Trained volunteer lay educators conducted individualized bedside education with the intervention group. Primary outcome was attendance at a post-hospitalization follow-up visit 7-10 days after discharge. Secondary outcomes included parent-reported asthma management behaviors, symptoms, and self-efficacy scores from a one month follow-up interview.

RESULTS

Post-hospitalization asthma clinic attendance was poor (38%), with no difference between groups. Families randomized to the intervention group were more likely to report use of a controller (OR 2.4, 95% CI 1.3-4.2, p<0.01) and a valved-holding chamber (OR 2.9, 95% CI 1.1-7.4, p=0.03), and were more likely to have an asthma action plan at follow up (OR 2.0, 95% CI 1.3-3.0, p<0.01). Asthma self-efficacy scores were significantly improved among those who received the intervention (p=0.04).

CONCLUSIONS

Inpatient asthma education by trained lay volunteers was associated with improved asthma management behaviors.

PRACTICE IMPLICATIONS

This novel volunteer-based program could have widespread implications as a sustainable model for asthma education.

Primary care visits for asthma monitoring over time and association with acute asthma visits for urban Medicaid-insured children

OBJECTIVES

To examine the association between numbers of primary care provider (PCP) visits for asthma monitoring (AM) over time and acute asthma visits in the emergency department (ED) and at the PCP for Medicaid-insured children.

METHODS

We prospectively enrolled 2-10 years old children during ED asthma visits. We audited hospital and PCP records for each subject for three consecutive years. We excluded subjects also receiving care from asthma subspecialists. PCP AM visits were those with documentation that suggested discussion of asthma management but no acute asthma symptoms or findings. PCP "Acute Asthma" visits were those with documentation of acute asthma symptoms or findings, regardless of treatment. ED asthma visits were those with documented asthma treatment. Generalized liner models were used to analyze the association between numbers of AM visits and acute asthma visits to the ED and PCP.

RESULTS

One hundred three subjects were analyzed. Over the 3 years, the mean number of AM visits/child was 2.5 ± 2.3 (standard deviation), range 0-10. Only 50% of subjects had at least 1 PCP visit with an asthma controller medication documented. The mean number of ED asthma visits/child was 3.2 ± 2.8; range 1-18. The mean number of PCP Acute Asthma visits/child was 0.7 ± 1.6; range 0-11. Increasing AM visits was associated with more ED visits (estimate 0.088; 95% CI 0.001, 0.174), and more PCP Acute Asthma visits (estimate 0.297; 95% CI 0.166, 0.429). Increasing PCP visits for any diagnosis was not associated with ED visits (estimate 0.021; 95% CI -0.018, 0.06).

CONCLUSIONS

Asthma monitoring visits and documented controller medication for these urban Medicaid-insured children occurred infrequently over 3 years, and having more asthma monitoring visits was not associated with fewer ED or PCP acute asthma visits.

ADRIC: Adverse Drug Reactions In Children – a programme of research using mixed methods

Aims

To comprehensively investigate the incidence, nature and risk factors of adverse drug reactions (ADRs) in a hospital-based population of children, with rigorous assessment of causality, severity and avoidability, and to assess the consequent impact on children and families. We aimed to improve the assessment of ADRs by development of new tools to assess causality and avoidability, and to minimise the impact on families by developing better strategies for communication.

Review methods

Two prospective observational studies, each over 1 year, were conducted to assess ADRs in children associated with admission to hospital, and those occurring in children who were in hospital for longer than 48 hours. We conducted a comprehensive systematic review of ADRs in children. We used the findings from these studies to develop and validate tools to assess causality and avoidability of ADRs, and conducted interviews with parents and children who had experienced ADRs, using these findings to develop a leaflet for parents to inform a communication strategy about ADRs.

Results

The estimated incidence of ADRs detected in children on admission to hospital was 2.9% [95% confidence interval (CI) 2.5% to 3.3%]. Of the reactions, 22.1% (95% CI 17% to 28%) were either definitely or possibly avoidable. Prescriptions originating in the community accounted for 44 out of 249 (17.7%) of ADRs, the remainder originating from hospital. A total of 120 out of 249 (48.2%) reactions resulted from treatment for malignancies. Off-label and/or unlicensed (OLUL) medicines were more likely to be implicated in an ADR than authorised medicines [relative risk (RR) 1.67, 95% CI 1.38 to 2.02;p < 0.001]. When medicines used for the treatment of oncology patients were excluded, OLUL medicines were not more likely to be implicated in an ADR than authorised medicines (RR 1.03, 95% CI 0.72 to 1.48;p = 0.830). For children who had been in hospital for > 48 hours, the overall incidence of definite and probable ADRs based on all admissions was 15.9% (95% CI 15.0 to 16.8). Opiate analgesic drugs and drugs used in general anaesthesia (GA) accounted for > 50% of all drugs implicated in ADRs. The odds ratio of an OLUL drug being implicated in an ADR compared with an authorised drug was 2.25 (95% CI 1.95 to 2.59;p < 0.001). Risk factors identified were exposure to a GA, age, oncology treatment and number of medicines. The systematic review estimated that the incidence rates for ADRs causing hospital admission ranged from 0.4% to 10.3% of all children [pooled estimate of 2.9% (95% CI 2.6% to 3.1%)] and from 0.6% to 16.8% of all children exposed to a drug during hospital stay. New tools to assess causality and avoidability of ADRs have been developed and validated. Many parents described being dissatisfied with clinician communication about ADRs, whereas parents of children with cancer emphasised confidence in clinician management of ADRs and the way clinicians communicated about medicines. The accounts of children and young people largely reflected parents’ accounts. Clinicians described using all of the features of communication that parents wanted to see, but made active decisions about when and what to communicate to families about suspected ADRs, which meant that communication may not always match families’ needs and expectations. We developed a leaflet to assist clinicians in communicating ADRs to parents.

Conclusion

The Adverse Drug Reactions In Children (ADRIC) programme has provided the most comprehensive assessment, to date, of the size and nature of ADRs in children presenting to, and cared for in, hospital, and the outputs that have resulted will improve the management and understanding of ADRs in children and adults within the NHS. Recommendations for future research: assess the values that parents and children place on the use of different medicines and the risks that they will find acceptable within these contexts; focusing on high-risk drugs identified in ADRIC, determine the optimum drug dose for children through the development of a gold standard practice for the extrapolation of adult drug doses, alongside targeted pharmacokinetic/pharmacodynamic studies; assess the research and clinical applications of the Liverpool Causality Assessment Tool and the Liverpool Avoidability Assessment Tool; evaluate, in more detail, morbidities associated with anaesthesia and surgery in children, including follow-up in the community and in the home setting and an assessment of the most appropriate treatment regimens to prevent pain, vomiting and other postoperative complications; further evaluate strategies for communication with families, children and young people about ADRs; and quantify ADRs in other settings, for example critical care and neonatology.

Improving preventive care in high risk children with asthma: lessons learned

OBJECTIVES

Rates of preventive asthma care after an asthma emergency department (ED) visit are low among inner-city children. The objective of this study was to test the efficacy of a clinician and caregiver feedback intervention (INT) on improving preventive asthma care following an asthma ED visit compared to an attention control group (CON).

METHODS

Children with persistent asthma and recent asthma ED visits (N = 300) were enrolled and randomized into a feedback intervention or an attention control group and followed for 12 months. All children received nurse visits. Data were obtained from interviews, child salivary cotinine levels and pharmacy records. Standard t-test, chi-square and multiple logistic regression tests were used to test for differences between the groups for reporting greater than or equal to two primary care provider (PCP) preventive care visits for asthma over 12 months.

RESULTS

Children were primarily male, young (3-5 years), African American and Medicaid insured. Mean ED visits over 12 months was high (2.29 visits). No difference by group was noted for attending two or more PCP visits/12 months or having an asthma action plan (AAP). Children having an AAP at baseline were almost twice as likely to attend two or more PCP visits over 12 months while controlling for asthma control, group status, child age and number of asthma ED visits.

CONCLUSIONS

A clinician and caregiver feedback intervention was unsuccessful in increasing asthma preventive care compared to an attention control group. Further research is needed to develop interventions to effectively prevent morbidity in high risk inner-city children with frequent ED utilization.

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.

Parental education on asthma severity in the emergency department and primary care follow-up rates

Asthma is the most prevalent chronic condition affecting children and a common chief complaint in emergency departments (EDs). We aimed to improve parents' understanding of their child's asthma severity on accessing our pediatric ED for an acute asthma exacerbation. A retrospective chart review was conducted to determine outpatient follow-up rates from our ED in 2010-2011. In an attempt to educate parents at ED discharge about their child's asthma severity at presentation, we included a visual severity scale on their discharge instructions. Postdischarge telephone interviews were completed to determine postintervention follow-up rates. Asthma follow-up rates at 1 week improved from 20.8% to 50% after intervention. This difference was statistically significant after controlling for age and clinical asthma score with logistic regression (P < .0001). Offering predischarge education about a child's initial asthma severity is a simple intervention that significantly improved follow-up rates for children seen in the ED for asthma exacerbation.

Factors associated with completion of a behavioral intervention for caregivers of urban children with asthma

BACKGROUND

Rates of preventive follow-up asthma care after an acute emergency department (ED) visit are low among inner-city children. We implemented a novel behavioral asthma intervention, Pediatric Asthma Alert (PAAL) intervention, to improve outpatient follow-up and preventive care for urban children with a recent ED visit for asthma.

OBJECTIVE

The objective of this article is to describe the PAAL intervention and examine factors associated with intervention completers and noncompleters.

METHODS

Children with persistent asthma and recurrent ED visits (N = 300) were enrolled in a randomized controlled trial of the PAAL intervention that included two home visits and a facilitated follow-up visit with the child's primary care provider (PCP). Children were categorized as intervention completers, that is, completed home and PCP visits compared with noncompleters, who completed at least one home visit but did not complete the PCP visit. Using chi-square test of independence, analysis of variance, and multiple logistic regression, the intervention completion status was examined by several sociodemographic, health, and caregiver psychological variables.

RESULTS

Children were African-American (95%), Medicaid insured (91%), and young (aged 3-5 years, 56%). Overall, 71% of children randomized to the intervention successfully completed all home and PCP visits (completers). Factors significantly associated with completing the intervention included younger age (age 3-5 years: completers, 65.4%; noncompleters, 34.1%; p < .001) and having an asthma action plan in the home at baseline (completers: 40%; noncompleters: 21%; p = .02). In a logistic regression model, younger child age, having an asthma action plan, and lower caregiver daily asthma stress were significantly associated with successful completion of the intervention.

CONCLUSIONS

The majority of caregivers of high-risk children with asthma were successfully engaged in this home and PCP-based intervention. Caregivers of older children with asthma and those with high stress may need additional support for program completion. Further, the lack of an asthma action plan may be a marker of preexisting barriers to preventive care.

Inappropriate home albuterol use during an acute asthma exacerbation

BACKGROUND

Increased asthma morbidity and mortality is associated with inappropriate home self-management skills.

OBJECTIVES

To examine the proportion of children presenting to the emergency department (ED) with an acute asthma exacerbation with incorrect home use of their albuterol inhaler and to identify factors associated with improper treatment.

METHODS

Caregivers of children with asthma aged 4 to 14 years, presenting to the ED with an asthma exacerbation, participated in the study. Interviewers collected caregiver's perceived severity of the asthma exacerbation and home albuterol use before the ED visit. National Asthma Education and Prevention Program guidelines were used to classify home albuterol use as appropriate or inappropriate.

RESULTS

Home albuterol use for the current asthma exacerbation was categorized as inappropriate (56 [68%]) and appropriate (26 [32%]) for 84 participants. Thirty-nine of the inappropriate group undertreated, with 24 not giving albuterol frequently enough and 15 without albuterol at home. Other reasons for incorrect home albuterol use included: no spacer, overtreating, overreacting, and using a controller medicine for quick relief. Those with appropriate albuterol use were more likely to have their child hospitalized for asthma in the past 48 months (P=.004). Caregivers with inappropriate use perceived their child's asthma exacerbation as more severe (P<.001) compared with physician rating. Physicians rated asthma severity higher in the appropriate group than the inappropriate group (P<.001).

CONCLUSION

A significant proportion of caregivers incorrectly treat children's asthma exacerbation with albuterol. Despite perceiving their children's asthma exacerbations as more severe, most undertreat with albuterol. Correctly assessing asthma symptom severity and appropriate home albuterol use may be linked to disease experience.

Enhancing communication about paediatric medicines: lessons from a qualitative study of parents' experiences of their child's suspected adverse drug reaction

Background

There is little research on parents' experiences of suspected adverse drug reactions in their children and hence little evidence to guide clinicians when communicating with families about problems associated with medicines.

Objective

To identify any unmet information and communication needs described by parents whose child had a suspected adverse drug reaction.

Methods

Semi-structured qualitative interviews with parents of 44 children who had a suspected adverse drug reaction identified on hospital admission, during in-patient treatment or reported by parents using the Yellow Card Scheme (the UK system for collecting spontaneous reports of adverse drug reactions). Interviews were conducted face-to-face or by telephone; most interviews were audiorecorded and transcribed. Analysis was informed by the principles of the constant comparative method.

Results

Many parents described being dissatisfied with how clinicians communicated about adverse drug reactions and unclear about the implications for their child's future use of medicines. A few parents felt that clinicians had abandoned their child and reported refusing the use of further medicines because they feared a repeated adverse drug reaction. The accounts of parents of children with cancer were different. They emphasised their confidence in clinicians' management of adverse drug reactions and described how clinicians prospectively explained the risks associated with medicines. Parents linked symptoms to medicines in ways that resembled the established reasoning that clinicians use to evaluate the possibility that a medicine has caused an adverse drug reaction.

Conclusion

Clinicians' communication about adverse drug reactions was poor from the perspective of parents, indicating that improvements are needed. The accounts of parents of children with cancer indicate that prospective explanation about adverse drug reactions at the time of prescription can be effective. Convergence between parents and clinicians in their reasoning for linking children's symptoms to medicines could be a starting point for improved communication.

Low rates of follow-up with primary care providers after pediatric emergency department visits for respiratory tract illnesses

OBJECTIVES

We sought to determine diagnosis-specific rates of follow-up with primary care providers (PCPs) after emergency department (ED) visits for respiratory tract illnesses. We hypothesized that follow-up rates would be higher among patients with acute infectious illnesses than among those with asthma.

METHODS

This was a retrospective cohort study of a random sample of patients aged 0 to 12 years discharged over a 12-month period from an urban, tertiary care pediatric ED with 4 different respiratory tract illnesses (asthma, bronchiolitis, croup, and pneumonia). Primary care provider follow-up was examined for associations with sociodemographic and clinical factors and with subsequent ED visits.

RESULTS

Rates of follow-up in the overall cohort were low: 23.6% (95% confidence interval, 19.7-27.4) by 7 days and 40.5% (95% confidence interval, 36.0-44.9) by 30 days. Compared with patients with asthma, the relative risks (RRs) of follow-up within 7 and 30 days were significantly higher among patients with bronchiolitis and pneumonia, but not with croup. For the cohort as a whole, the RR of follow-up within 7 and 30 days significantly decreased for each 1-year increase in age, and the RR of follow-up within 7 days significantly increased with the provision of explicit ED discharge instructions recommending follow-up. Among patients with asthma, follow-up with PCPs within 30 days was not associated with decreased ED visits for asthma over the following year.

CONCLUSIONS

Rates of PCP follow-up were globally low but significantly higher for patients with acute infectious illnesses, for younger patients, and for those receiving explicit ED discharge instructions.

The Joint Commission Children's Asthma Care quality measures and asthma readmissions

BACKGROUND AND OBJECTIVES

The Joint Commission introduced 3 Children's Asthma Care (CAC 1-3) measures to improve the quality of pediatric inpatient asthma care. Validity of the commission's measures has not yet been demonstrated. The objectives of this quality improvement study were to examine changes in provider compliance with CAC 1-3 and associated asthma hospitalization outcomes after full implementation of an asthma care process model (CPM).

METHODS

The study included children aged 2 to 17 years who were admitted to a tertiary care children's hospital for acute asthma between January 1, 2005, and December 31, 2010. The study was divided into 3 periods: preimplementation (January 1, 2005-December 31, 2007), implementation (January 1, 2008-March 31, 2009), and postimplementation (April 1, 2009-December 31, 2010) periods. Changes in provider compliance with CAC 1-3 and associated changes in hospitalization outcomes (length of stay, costs, PICU transfer, deaths, and asthma readmissions within 6 months) were measured. Logistic regression was used to control for age, gender, race, insurance type, and time.

RESULTS

A total of 1865 children were included. Compliance with quality measures before and after the CPM implementation was as follows: 99% versus 100%, CAC-1; 100% versus 100%, CAC-2; and 0% versus 87%, CAC-3 (P < .01). Increased compliance with CAC-3 was associated with a sustained decrease in readmissions from an average of 17% to 12% (P = .01) postimplementation. No change in other outcomes was observed.

CONCLUSIONS

Implementation of the asthma CPM was associated with improved compliance with CAC-3 and with a delayed, yet significant and sustained decrease in hospital asthma readmission rates, validating CAC-3 as a quality measure. Due to high baseline compliance, CAC-1 and CAC-2 are of questionable value as quality measures.

Follow-up care after an emergency department visit for asthma and subsequent healthcare utilization in a universal-access healthcare system

OBJECTIVES

To describe the follow-up care within 28 days of an emergency department (ED) visit for asthma and to determine the association of follow-up visits within 28 days with ED re-visits and hospital admissions in the subsequent year.

STUDY DESIGN

Population-based retrospective cohort study of children with asthma aged 2-17 years treated in an ED in Ontario, Canada between April 14, 2006 and February 28, 2009. Multiple linked health administrative datasets and Cox proportional hazard multivariable survival models were used to test the association of characteristics of 28-day follow-up visits with 1-year outcomes.

RESULTS

The final cohort consisted of 29391 children, of whom 32.8% had follow-up, 6496 (22.1%) had an ED re-visit, and 801 (2.7%) had a hospital admission. Having a follow-up visit was not associated with ED re-visit or hospitalizations (hazard ratio 0.98; 95% CI 0.93, 1.03 and hazard ratio 1.06; 95% CI 0.92, 1.23, respectively). Younger children and those with indices of more severe acute or chronic asthma were more likely to have ED re-visits and hospitalizations. Other follow-up care characteristics (number of visits, type of physician providing care) were not associated with outcomes.

CONCLUSIONS

Despite a universal healthcare setting, most children did not access follow-up care after an ED visit for asthma, and those that did had no associated benefit in terms of reduced ED re-visits and hospitalizations in the subsequent year.

Partner randomized controlled trial: study protocol and coaching intervention

BACKGROUND

Many children with asthma live with frequent symptoms and activity limitations, and visits for urgent care are common. Many pediatricians do not regularly meet with families to monitor asthma control, identify concerns or problems with management, or provide self-management education. Effective interventions to improve asthma care such as small group training and care redesign have been difficult to disseminate into office practice.

METHODS AND DESIGN

This paper describes the protocol for a randomized controlled trial (RCT) to evaluate a 12-month telephone-coaching program designed to support primary care management of children with persistent asthma and subsequently to improve asthma control and disease-related quality of life and reduce urgent care events for asthma care. Randomization occurred at the practice level with eligible families within a practice having access to the coaching program or to usual care. The coaching intervention was based on the transtheoretical model of behavior change. Targeted behaviors included 1) effective use of controller medications, 2) effective use of rescue medications and 3) monitoring to ensure optimal control. Trained lay coaches provided parents with education and support for asthma care, tailoring the information provided and frequency of contact to the parent's readiness to change their child's day-to-day asthma management. Coaching calls varied in frequency from weekly to monthly. For each participating family, follow-up measurements were obtained at 12- and 24-months after enrollment in the study during a telephone interview. The primary outcomes were the mean change in 1) the child's asthma control score, 2) the parent's quality of life score, and 3) the number of urgent care events assessed at 12 and 24 months. Secondary outcomes reflected adherence to guideline recommendations by the primary care pediatricians and included the proportion of children prescribed controller medications, having maintenance care visits at least twice a year, and an asthma action plan. Cost-effectiveness of the intervention was also measured.

DISCUSSION

Twenty-two practices (66 physicians) were randomized (11 per treatment group), and 950 families with a child 3-12 years old with persistent asthma were enrolled. A description of the coaching intervention is presented.

Low rates of controller medication initiation and outpatient follow-up after emergency department visits for asthma

OBJECTIVE

To determine what proportion of patients who are seen in an emergency department (ED) for asthma receive inhaled corticosteroids or attend follow-up appointments.

STUDY DESIGN

This was a retrospective cohort study of 2007-2009 South Carolina Medicaid data. Enrollees aged 2-18 years who had an ED visit for asthma were included. Patients admitted for asthma or with an inhaled corticosteroid claim in the 2 months before the month of the ED visit were excluded. Covariates were sex, race, age, rural residence, and asthma severity. Outcome measures were a prescription for an inhaled corticosteroid filled within the 2 months after the ED visit and attendance at a follow-up appointment within the 2 months after the ED visit.

RESULTS

A total of 3435 patients were included. Out of the study cohort, 57% were male, 76% were of a minority race/ethnicity, 69% lived in an urban areas, 18% had inhaled corticosteroid use, and 12% completed follow-up. Multivariate analyses demonstrated that patients with severe asthma were more likely to receive an inhaled corticosteroid (OR, 2.9; 95% CI, 2.3-3.7) and attend a follow-up appointment (OR, 2.0; 95% CI, 1.5-2.6). Patients aged 2-6 years and those aged >12 years were less likely to attend follow-up (OR, 0.71; 95% CI, 0.56-0.90 and OR, 0.62; 95% CI, 0.47-0.83, respectively) (all models P < .0001).

CONCLUSION

Children with asthma seen in the ED have low rates of inhaled corticosteroid use and outpatient follow-up. This indicates a need for further interventions to increase the use of inhaled corticosteroids in response to ED visits.

Under-utilization of controller medications and poor follow-up rates among hospitalized asthma patients

OBJECTIVE

Recommended preventive care following an asthma admission includes prescribing controller medications and encouraging outpatient follow-up. We sought to determine (1) the proportion of patients who receive controller medications or attend follow-up after asthma admission and (2) what factors predict these outcomes.

METHODS

South Carolina Medicaid data from 2007-2009 were analyzed. Patients who were included were 2 to 18 years old, and had at least one admission for asthma. Variables examined were: age, gender, race, and rural location. Outcome variables were controller medication prescription and follow-up appointment. Any claim for an inhaled corticosteroid (ICS) or ICS/long-acting beta-agonist in the 2 months after admission was considered appropriate. Any outpatient visit for asthma in the 2 months after admission was considered appropriate. Bivariate analyses used chi-square tests. Logistic regression models identified factors that predict controller medications and follow-up.

RESULTS

Five hundred five patients were included, of whom 60% were male, 79% minority race/ethnicity, and 58% urban. Rates of receiving controller medications and attending follow-up appointments were low, and an even lower proportion received both. Overall, 52% received a controller medication, 49% attended follow-up, and 32% had both. Multivariable analyses demonstrated that patients not of minority race or ethnicity were more likely to receive controller medications (odds ratio, 1.7; 95% confidence interval, 1.1-2.6).

CONCLUSIONS

Patients with asthma admitted for acute exacerbations in South Carolina have low rates of controller medication initiation and follow-up attendance. Minority race/ethnicity patients are less likely to receive controller medications. To decrease rates of future exacerbations, inpatient providers must improve the rates of preventive care delivery in the acute care setting with a focus on racial/ethnic minority populations.

Parental preferences for FDA-approved medications prescribed for their children

OBJECTIVE

To describe parental preferences for FDA-approved prescription medications for their children.

STUDY DESIGN

Cross-sectional Web-enabled survey of a national sample of 1562 parents.

RESULTS

Response rate was 61%. Most parents (77%) preferred prescription of only FDA-approved medications for their child. However, one half of parents preferred that their child's doctor prescribe medication that is safest and works best, even if not FDA approved for children. One third of parents (34%) preferred nothing but FDA-approved medications for their child, regardless of drug safety, effectiveness, or cost. Controlling for parent race and education, mothers (odds ratio = 1.52; P = .004) and older parents (odds ratio = 1.60; P = .025) were more likely to prefer nothing but FDA-approved medications for their children compared with fathers and younger parents.

CONCLUSIONS

Although most parents initially indicate preference for FDA-approved medications, one half of parents will accept a non-FDA-approved medication for their children with the understanding that it is safer or more effective than the FDA-approved alternative.

Ecological barriers and social forces in childhood asthma management: examining routines of African American families living in the inner city

OBJECTIVE

Asthma affects African American children at unprecedented rates. Researchers have examined the context in which African American families live and experience illness, and suggest that ecological barriers contribute to poor health. In this paper, the authors examine the social forces underlying these ecological barriers and what African American parents living in the inner city do to manage their children's asthma amidst these challenges.

METHODS

African American parents of children aged 5 to 12 years diagnosed with persistent asthma living in the inner city were interviewed using a semistructured interview guide. Grounded theory analysis identified recurrent themes in the interview data.

FINDINGS

Parents identified four adaptive routines they use to manage their children's asthma: ( 1 ) give young children with asthma responsibility for medication use; ( 2 ) monitor the availability of the school nurse; ( 3 ) manage air quality; and ( 4 ) frequently clean the home. These routines are described as adaptive because parents navigate ecological barriers and social forces within their daily context to manage their children's asthma.

IMPLICATIONS

The authors argue that the first step in reducing the impact of ecological barriers is understanding African Americans' sociohistorical context.

Written action plan in pediatric emergency room improves asthma prescribing, adherence, and control

RATIONALE

An acute-care visit for asthma often signals a management failure. Although a written action plan is effective when combined with self-management education and regular medical review, its independent value remains controversial.

OBJECTIVES

We examined the efficacy of providing a written action plan coupled with a prescription (WAP-P) to improve adherence to medications and other recommendations in a busy emergency department.

METHODS

We randomized 219 children aged 1-17 years to receive WAP-P (n = 109) or unformatted prescription (UP) (n = 110). All received fluticasone and albuterol inhalers, fitted with dose counters, to use at the discretion of the emergency physician. The main outcome was adherence to fluticasone (use/prescribed × 100%) over 28 days. Secondary outcomes included pharmacy dispensation of oral corticosteroids, β(2)-agonist use, medical follow-up, asthma education, acute-care visits, and control.

MEASUREMENTS AND MAIN RESULTS

Although both groups showed a similar drop in adherence in the initial 14 days, adherence to fluticasone was significantly higher over Days 15-28 in children receiving WAP-P (mean group difference, 16.13% [2.09, 29.91]). More WAP-P than UP patients filled their oral corticosteroid prescription (relative risk, 1.31 [1.07, 1.60]) and were well-controlled at 28 days (1.39 [1.04, 1.86]). Compared with UP, use of WAP-P increased physicians' prescription of maintenance fluticasone (2.47 [1.53, 3.99]) and recommendation for medical follow-up (1.87 [1.48, 2.35]), without group differences in other outcomes.

CONCLUSIONS

Provision of a written action plan significantly increased patient adherence to inhaled and oral corticosteroids and asthma control and physicians' recommendation for maintenance fluticasone and medical follow-up, supporting its independent value in the acute-care setting. Clinical trial registered with www.clinicaltrials.gov (NCT 00381355).

Treatment adherence among low-income, African American children with persistent asthma

OBJECTIVE

The study aims to assess medication adherence and asthma management behaviors and their modifiable predictors in low-income children with persistent asthma.

METHODS

The authors conducted a cohort study of 143 children ages 6 to 11 prescribed a daily inhaled controller medicine that could be electronically monitored. Children were recruited from clinics or the emergency department of an urban children's hospital. Data were collected at baseline (T1) and 1 year later (T2). Outcome measures were adherence to controller medications as measured by electronic monitoring devices, observed metered-dose inhaler and spacer technique, exposure to environmental tobacco smoke, and attendance at appointments with primary health care provider.

RESULTS

Medication adherence rates varied across medications, with higher rates for montelukast than for fluticasone. Eleven percent to 15% of children demonstrated metered dose inhaler and spacer technique suggesting no drug delivery, and few (5% to 6%) evidenced significant exposure to environmental tobacco smoke. Less than half of recommended health care visits were attended over the study interval. Few psychosocial variables were associated with adherence at T1 or in the longitudinal analyses. Fluticasone adherence at T2 was predicted by caregiver asthma knowledge.

CONCLUSIONS

A substantial number of low-income children with persistent asthma receive less than half of their prescribed inhaled controller agent. Patients without Medicaid, with low levels of caregiver asthma knowledge, or with caregivers who began childrearing at a young age may be at highest risk for poor medication adherence.

Validation of the Asthma Illness Representation Scale (AIRS)

BACKGROUND

Research has suggested a link between parents' illness representations (IRs), use of complementary and alternative medicine, inhaled/oral corticosteroids and leukotriene antagonists, and children's health outcomes. The Asthma Illness Representation Scale (AIRS) provides a structured assessment of the key components of asthma IRs allowing the healthcare provider (HCP) to quickly identify areas of discordance with the professional model of asthma management.

METHODS

These analyses extend the initial validation of the AIRS and compares data from the original study conducted among a primarily white and African American sample in Rochester, NY (N = 228) with data obtained from a predominantly inner-city, ethnic minority sample (Puerto Rican, African American, and Afro-Caribbean) from the Bronx, New York (N = 109).

RESULTS

A larger proportion of the Rochester sample was white and non-poor and had graduated high school. Bronx parents were more likely to perceive their child's asthma to be moderate or severe than the Rochester parents. Bronx children were older and had longer duration of asthma and reported more acute health care visits (past year). Bronx parents reported total AIRS scores more closely aligned with the lay model than Rochester parents. The AIRS instrument demonstrated acceptable internal reliability among the Bronx sample (total score alpha = 0.82) and the AIRS subscale Cronbach's alpha coefficients were remarkably similar to those obtained from the original validation study (range = 0.54-0.83). Poor parents and those with less than a high school education had lower total AIRS scores than their counterparts. White parents had AIRS scores more closely aligned with the professional model compared to each of the ethnic subgroups. A perception of less severe asthma, fewer reports of asthma and somatization symptoms, and a positive HCP relationship were associated with IRs congruent with the professional model. IRs aligned with the professional model were associated with fewer acute asthma-related healthcare visits.

CONCLUSIONS

The AIRS instrument exhibited good internal reliability, external validity, and differentiated parents based on ethnicity, poverty, and education. Assessment of asthma IRs during the healthcare visit will allow the HCP and parent to discuss and negotiate a shared asthma management plan for the child, which will hopefully lead to improved medication adherence and asthma health outcomes.

Does pre-hospital telephone communication with a clinician result in more appropriate medication administration by parents during childhood asthma exacerbations?

BACKGROUND

The National Heart, Lung and Blood Institute asthma guidelines recommend that parents communicate with a clinician during childhood asthma exacerbations when symptoms worsen or do not improve with initial therapy. This study tested the hypothesis that communication by parents with a clinician before an Emergency Department visit was associated with more appropriate medication administration for children with asthma exacerbations.

METHODS

This was a retrospective cohort study using data gathered from parents of children presenting with an asthma exacerbation to the emergency department. The communicating cohort included parents who communicated by telephone with a clinician during the exacerbation and the non-communicating cohort included parents who did not. Multivariate logistic regression models were used to test three hypotheses; communication with a clinician is associated with (1) administration of short-acting beta-agonists (SABAs), (2) increased dosing frequency of SABAs, and (3) administration of an oral corticosteroid.

RESULTS

A total of 199 subjects were enrolled, with 104 (52.3%) in the communicating and 95 (47.7%) in the non-communicating cohort. There was an association between communication and provider practice type, with children who received routine care from a private practice provider more likely to communicate with the clinician than children in hospital-based clinics or community health centers (Adjusted OR 1.9, 95% CI 1.0-3.7). Impoverished children and children insured by Medicaid were less likely to communicate with a clinician (controlling for provider type). Parents who communicated with a clinician were more likely to administer a SABA (adjusted OR 3.6, 95% CI 1.3-9.4) and an oral corticosteroid (adjusted OR 3.3, 95% CI 1.3-8.4) but were not more likely to administer a SABA with increased dosing frequency (adjusted OR 0.9, 95% CI 0.5-1.6).

CONCLUSIONS

Parents of children with asthma exacerbations who communicated with clinicians were more likely to administer SABAs and an oral corticosteroid before bringing their child to an emergency department. Frequency of SABA dosing was not associated with communication. Clinicians providing telephone advice to parents need to provide explicit instructions about medication administration, emphasizing the frequency with which SABAs should be administered.

Beliefs and barriers to follow-up after an emergency department asthma visit: a randomized trial

BACKGROUND

Studies in urban emergency departments (EDs) have found poor quality of chronic asthma care and identified beliefs and barriers associated with low rates of follow-up with a primary care provider (PCP).

OBJECTIVES

To develop an ED-based intervention including asthma symptom screening, a video addressing beliefs and a mailed reminder; and measure the effect on PCP follow-up and asthma-related outcomes.

METHODS

This randomized, controlled trial enrolled children aged 1 to 18 years who were discharged after asthma treatment in an urban pediatric ED. Control subjects received instructions to follow-up with a PCP within 3 to 5 days. In addition, intervention subjects (1) received a letter to take to their PCP if they screened positive for persistent asthma symptoms, (2) viewed a video featuring families and providers discussing the importance of asthma control, and (3) received a mailed reminder to follow-up with a PCP. All subjects were contacted by telephone 1, 3, and 6 months after the ED visit, and follow-up was confirmed by PCP record review. Asthma-related quality of life (AQoL), symptoms, and beliefs about asthma care were assessed by using validated surveys.

RESULTS

A total of 433 subjects were randomly assigned, and baseline measures were similar between study groups. After the intervention and before ED discharge, intervention subjects were more likely to endorse beliefs about the benefits of follow-up than controls. However, rates of PCP follow-up during the month after the ED visit (44.5%) were similar to control subjects (43.8%) as were AQoL, medication use, and ED visits.

CONCLUSIONS

An ED-based intervention influenced beliefs but did not increase PCP follow-up or asthma-related outcomes.

What affects asthma medicine use in children? Australian asthma educator perspectives

The global burden of childhood asthma is significant. Health care systems are faced with increasing financial costs, while children with asthma and their caretakers are faced with poorer physical health, emotional health, and quality of life. Despite the availability of effective treatment, the quality use of asthma medicines in children remains suboptimal. An investigation was conducted to explore issues related to children's asthma medicine usage from the perspective of the health care professional. Although current literature has elicited the views of caretakers and children, the health care professional viewpoint has been relatively unexplored. Semi-structured qualitative interviews were conducted with a convenience sample of 21 Australian asthma educators. Interviews were audiotaped and transcribed, and transcripts were thematically analyzed with the assistance of NVivo 7. Emergent themes associated with health care professionals, parents, medicines, children, and educational resources were found. Major issues included a lack of information provided to parents, poor parental understanding of medicines, the high cost of medicines and devices, child self-image, the need for more child responsibility over asthma management, and the lack of standardization, access to, and funding for educational resources on childhood asthma. There are multitudes of key issues that may affect asthma medicines usage in children. This research will help inform the development of educational tools on the use of medicines in childhood asthma that can be evaluated for their effectiveness in getting key messages to target audiences such as children, caretakers, and teachers.

Demographic, socioeconomic, and psychological factors related to medication non-adherence among emergency department patients

BACKGROUND

Many Emergency Department (ED) visits are related to medication non-adherence; however, the contributing factors are poorly understood.

OBJECTIVES

To explore the relative contributions of demographic, socioeconomic, and psychological factors to medication non-adherence in an ED population.

METHODS

This was a cross-sectional analysis enrolling patients with one of three illnesses requiring chronic medication usage (hypertension, diabetes, or seizures). Trained research associates administered a 60-item survey that assessed demographic and socioeconomic information, as well as a variety of psychological factors potentially relevant to adherence (health attitudes, health beliefs, depression, anxiety, social support, and locus of control). Patients rated their overall prescription medication adherence and estimated the number of days in the preceding month on which doses were missed. In addition, treating physicians estimated the degree to which the ED visit was related to medication non-adherence; clinical data were abstracted to help validate patient and physician assessments. The relationships between non-adherence and demographic, socioeconomic, and psychological variables were explored using multivariate statistics and logistic regression. Covariance analysis was performed to validate subscales, and receiver-operator curves were used to define optimal threshold values.

RESULTS

A total of 472 patients consented to participate, with good representation for various demographic and socioeconomic groups. Each psychological factor related significantly to both patient and physician ratings of non-adherence (p < 0.05). Of all demographic and socioeconomic factors examined, only current or historical drug use predicted non-adherence.

CONCLUSIONS

Psychological factors seem to be important determinants of medication non-adherence among ED patients. These data may help define future research directions and interventions.

Childhood asthma: ED follow-up determinants

INTRODUCTION

This comparative correlational study investigated families who use the emergency department for childhood asthma to identify determinants of follow-up care. The primary hypothesis was: families who obtain follow-up care differ in predisposing, enabling, and need characteristics from families who do not obtain follow-up care.

METHOD

A convenience sample of 63 children presenting to the pediatric emergency department of a Central Florida hospital were enrolled. Logistic regression techniques were utilized to explicate the individual and combined effects of the variables that best predicted the outcome variable. The dichotomous dependent variable was follow-up care within 30 days of the ED visit.

RESULTS

Sixty-seven percent of the children did not follow up as directed. Mother's level of education was significantly associated with no follow-up (P = .0282). Odds of no follow-up were higher for children with more severe asthma (odds ratio [OR] 12.44) or older mothers (OR 2.14).

DISCUSSION

Follow-up is not occurring at desired levels. Although this study has clinical and research implications for health care providers, further research is needed to identify follow-up determinants and develop interventions to improve follow-up rates and asthma outcomes.

[Bronchial asthma in children. Furthering compliance]

Success in treating and managing bronchial asthma in children and adolescents is known to rely on active cooperation on behalf of both the patients and their parents. Compliance in terms of pharmaceutical or behavioural intervention is often insufficient to prevent further aggravation and exacerbation. Specific measures for enhancing therapy compliance have been well received in the German Health Care System, and research results indicate their effectiveness in reducing health care utilization and in improving quality of life. Studies that would ascribe such effects to regular medication intake or reduced exposure to allergic elicitors, however, are still lacking.

Parenting asthmatic children: identification of parenting challenges

Asthma is the most common chronic illness of childhood, affecting up to 14% of children. Poor asthma management and non-adherence to treatment regimens are a pervasive problem in this population and are related to exacerbation of symptoms. Effective management of pediatric asthma involves a complex set of interactions between the parent and child, yet there is a paucity of literature examining these interactions. The main purpose of this study was to identify the child behavior and asthma management tasks parents experience difficulty with. It was hypothesized that the more asthma behavior problems reported, the more problems parents experience in asthma management tasks. Participants in this study were 255 parents of 2-to 10-year-old asthmatic children, recruited via an advertisement placed in school newsletters throughout Australia. Results indicated that the most problematic child asthma behaviors were oppositional behavior, hyperactivity, and aggression, and anxiety was also identified by parents as a concern. The main problematic asthma parenting tasks were entrusting the school, entrusting caregivers, identifying unique symptoms, and identifying and avoiding triggers. More problem asthma behaviors were associated with higher levels of parenting difficulty and more general levels of behavior problems. Parents who reported more dysfunctional parenting styles reported more difficulties with their child's asthma behavior. Based on the results it is suggested that an appropriate parenting intervention program would target basic behavioral management skills, in addition to applying these behavior management principles to asthma management.

Socioeconomic factors and asthma control in children

OBJECTIVES

The objective of this study was to evaluate the association between socioeconomic factors and asthma control in children, as defined by the Canadian Pediatric Asthma Consensus Guidelines.

PATIENTS AND METHODS

Cross-sectional data from a completed study of 879 asthmatic children between the ages of 1 and 18 residing in the Greater Toronto Area were used. The database included data on demographics, health status, asthma control, and health-related quality of life. Stepwise forward modeling multiple regression was used to investigate the impact of socioeconomic status on asthma control, based on six control parameters from the 2003 Canadian Pediatric Asthma Consensus Guidelines.

RESULTS

Only 11% of patients met the requirements for acceptable control, while 20% had intermediate control, and 69% had unacceptable asthma control. Children from families in lower income adequacy levels had poorer control.

CONCLUSIONS

Disparities in asthma control between children from families of different socio-economic strata persist, even with adjustment for utilization of primary care services and use of controller medications.

Health disparities in the United States: childhood asthma

During the last 3 decades, asthma prevalence and morbidity in the United States have dramatically increased. The impact of this chronic respiratory disease has been disproportionately high among inner city residents, particularly lower socioeconomic groups, ethnic minorities, and children. A wide variety of factors have been shown to have an influence-indeed, the asthma epidemic is a chronicle of the ways in which environmental, social, and economic factors superimposed on inadequate health care delivery systems can converge to influence health status and the course of a chronic disease. Effective intervention strategies for this controllable disease must circumvent existing societal barriers to care and provide a comprehensive, structured program that emphasizes asthma controller therapy, disease-specific education, and regular periodic assessment of asthma control, preferably in a convenient, familiar setting that promotes patient engagement.

Predictors of asthma medication nonadherence

BACKGROUND

The purpose of this study was to describe asthma medication adherence behavior and to identify predictors of inhaled corticosteroid (ICS) underuse and inhaled beta-agonist (IBA) overuse.

METHODS

Self-reported medication adherence, spirometry, various measures of status, and blood for immunoglobulin E measurement were collected on 158 subjects from a larger cohort of adults with asthma and rhinitis who were prescribed an ICS, an IBA, or both.

RESULTS

There was a positive association between ICS underuse and higher forced expiratory volume in one second percent (FEV1%) predicted (P = .01) and a negative association with lower income (P = 0.04). IBA overuse was positively associated with greater perceived severity of asthma (P = 0.004) and negatively with higher education level (P = 0.02).

CONCLUSIONS

Nonadherence to prescribed asthma therapy seems to be influenced by socioeconomic factors and by perceived and actual severity of disease. These factors are important to assess when trying to estimate the degree of medication adherence and its relationship to clinical presentation.

Asthma

Asthma has been recognized as a disease since the earliest times. In the Corpus Hippocraticum, Hippocrates used the term “ασθμα” to indicate any form of breathing difficulty manifesting itself by panting. Aretaeus of Cappadocia, a well-known Greek physician (second century A.D.), is credited with providing the first detailed description of an asthma attack [13], and to Celsus it was a disease with wheezing and noisy, violent breathing. In the history of Rome, we find many members of the Julio-Claudian family affected with probable atopic respiratory disorders: Caesar Augustus suffered from bronchoconstriction, seasonal rhinitis as well as a highly pruritic skin disease. Claudius suffered from rhinoconjunctivitis and Britannicus was allergic to horse dander [529]. Maimonides (1136–1204) warned that to neglect treatment of asthma could prove fatal, whereas until the 19th century, European scholars defined it as “nervous asthma,” a term that was given to mean a defect of conductivity of the ninth pair of cranial nerves.

Medical services and prescription use for asthma and factors that predict inhaled corticosteroid use among African-American children covered by Medicaid

Many African-American children with asthma are inadequately treated with controller pharmacotherapy. We analyzed 2002 West Virginia Medicaid claims for 300 African-American children to determine demographic and health services use factors that predict inhaled corticosteroid (ICS) use. Approximately 38% of the children had a prescription claim for an ICS. Logistic regression showed a direct relationship between the number of claims for short-acting beta-agonists and oral corticosteroids and the likelihood of a child having a claim for an ICS. Children who used a controller agent other than an ICS also were more likely to have filled a prescription for an ICS. We conclude that children in our sample whose prescription use indicated more severe asthma were more likely to have used an ICS. Barriers to adequate pharmacotherapy for African-American children with asthma should be considered during the process of care.

Testing an intervention to promote children's adherence to asthma self-management

PURPOSE

To test the hypothesis that compared with the control group, 7 through 11-year-old children with persistent asthma who received asthma education plus a contingency management behavioral protocol would show higher adherence to peak expiratory flow (PEF) monitoring for asthma self-management and would report fewer asthma episodes.

DESIGN AND METHODS

A randomized, controlled trial was conducted with 77 children with persistent asthma in a southeastern U.S. state. Both the intervention and control groups received instruction on PEF monitoring. Only the intervention group received asthma education plus contingency management, based on cognitive social learning theory, including self-monitoring, a contingency contract, tailoring, cueing, and reinforcement. At-home adherence to daily PEF monitoring during the 16-week study was assessed with the AccuTrax Personal Diary Spirometer, a computerized hand-held meter. Adherence was measured as a percentage of prescribed daily PEF uses at Weeks 4 (baseline), 8 (postintervention), and 16 (maintenance).

RESULTS

At the end of the baseline period, the groups did not differ in adherence to daily PEF monitoring nor at Week 8. At Week 16, the intervention group's adherence for daily electronically monitored PEF was higher than that of the control group. Children in either group who were >or= 80% adherent to at least once-daily PEF monitoring during the last week of the maintenance period (weeks 8 to 16) were less likely to have an asthma episode during this period compared with those who were less adherent.

CONCLUSIONS

The intervention to teach children to adhere to the recommended regimen for managing their asthma at home was effective.

Achieving and maintaining asthma control in an urban pediatric disease management program: the Breathmobile Program

BACKGROUND

National guidelines suggest that, with appropriate care, most patients can control their asthma. The probabilities of children achieving and maintaining control with ongoing care are unknown.

OBJECTIVE

We sought to evaluate the degree to which children in a lower socioeconomic urban setting achieve and maintain control of asthma with regular participation in a disease management program that provides guideline-based care.

METHODS

Interdisciplinary teams of asthma specialists use mobile clinics to offer ongoing care at schools and county clinics. A guideline-derived construct of asthma control is recorded at each visit.

RESULTS

Two thousand one hundred eighty-five enrollees were eligible to evaluate the time to first achieve control, and 1591 patients were eligible to evaluate subsequent control maintenance. Depending on severity, 70% to 87% of patients with persistent asthma achieved control by visit 3, and 89% to 98% achieved control by visit 6. Subsequent control maintenance was highly variable. Thirty-nine percent of patients displayed well-controlled asthma (control at >90% of subsequent visits), whereas 13% displayed difficult-to-control asthma (<50% of subsequent visits). Patients from each baseline severity category were found in each group. Maintenance of control was influenced by physician-estimated compliance with the treatment plan, baseline severity, and the interval between clinic visits.

CONCLUSIONS

Many children can achieve asthma control with regular visit intervals and guideline-based care; however, long-term control can be highly variable among patients in all severity categories.

CLINICAL IMPLICATIONS

These findings highlight the need and feasibility for systematically tracking each patient's clinical response to individualize therapy and guide the use of population management strategies.
