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.     

Enhancing Medication Adherence Among Inner-City Children with Asthma: Results from Pilot Studies

Despite the availability of effective treatments that aid in controlling asthma symptoms, inner-city children with asthma have high rates of morbidity and are frequent users of emergency department services. The goal of these studies was to pilot test an intervention that used social learning strategies (e.g., goal-setting, monitoring, feedback, reinforcement, and enhanced self-efficacy) and targeted known barriers to individualize a family-based asthma action plan. Participants were 15 children with asthma, aged 7-12 years, who had been prescribed at least one daily inhaled steroid. The children and their mothers lived in inner-city Baltimore and all were African-American. Participants received up to five visits in their home by a nurse. Electronic monitors were installed on the children's MDI to provide immediate feedback on medication adherence to the families and validate medication use. At baseline, only 28.6% of the children were using their medications as prescribed. Within four weeks, the number of children who were using their medications appropriately doubled from 28.6% at baseline to 54.1% (90% increase; p = 0.004), while underutilization decreased from 51.2% to 25.4% (100% decrease; p = 0.02). The number of children with no medication use at all dropped from 28.3% at baseline to 15.1% by week 5 (87% decrease; p = 0.009). Thus, within four weeks, more than half the children were using their inhaled steroids appropriately. In addition, the rate of underutilization decreased and that of nonutilization was cut in half. Our initial data suggest that an individualized, home-based intervention can significantly enhance adherence to the daily use of inhaled steroids in inner-city children with asthma. Nevertheless, adherence to daily inhaled steroid therapy remains a significant problem in this group.     

Asthma Management Practices at Home in Young Inner-City Children

Information on parental asthma management practices for young children is sparse. The objective of this article is to determine if specific caregiver asthma management practices for children were associated with children's asthma morbidity. Caregivers of 100 inner-city children diagnosed with persistent asthma and participating in an ongoing asthma intervention study were enrolled and interviewed to ascertain measures of asthma morbidity, medication use, health care use (acute and primary care), and asthma management practices. Overall, asthma morbidity was high with almost two thirds of caregivers reporting their child having one or more emergency department visits within the last 6 months and 63% receiving specialty care for their asthma. Appropriate medication use was reported predominantly as albuterol and inhaled steroids (78%). However, only 42% of caregivers reported administering asthma medicines when their child starts to cough and less than half (39%) reported having an asthma action plan. There were no significant differences by asthma severity level for any asthma management practice. In conclusion, caregivers lack knowledge regarding cough as an early asthma symptom. Caregivers should be encouraged to review asthma action plans with health care providers at each medical encounter.

Food allergy and asthma morbidity in children

BACKGROUND: Coexisting food allergy and asthma is a significant problem in the pediatric population. Studies have looked at the association between food sensitization and asthma severity. It is unknown whether specific food allergies are associated with increased asthma morbidity. OBJECTIVE: We studied the independent effect that allergy to egg, milk, fish, and peanut has on the number of hospitalizations and courses of systemic steroids in children with asthma. METHODS: We performed a medical record review to evaluate the effect food allergy to egg, fish, peanut, and milk has on asthma morbidity. We reviewed the records of 201 children aged 3 months to 14 years with the diagnosis of asthma (ICD-9 codes 493.90, 493.91, and 493.92), of which 88 had coexistent food allergy. All children in the food allergy group had food-specific IgE concentrations greater than the 95% positive predictive value. We compared the rate of hospitalizations and use of systemic steroids between children with asthma and food allergies and those without coexisting food allergy using direct-entry, multiple regression analysis. Patients were adjusted for the severity of their asthma based on symptoms documented at their first visit to the allergist according to the National Asthma Education and Prevention Program guidelines and presence of environmental allergy, eczema, smoke exposure, and gastroesophageal reflux. RESULTS: Peanut and milk allergies were both associated with increased number of hospitalizations (P=0.009, 0.016), and milk allergy was associated with increased use of systemic steroids (P=0.001). CONCLUSION: Peanut and milk allergies were associated with increased hospitalization and steroid use and may serve as early markers for increased asthma morbidity.     

Using a revised asthma morbidity index to identify varying patterns of morbidity in U.K. general practices

Both in terms of morbidity and mortality, the therapeutic and organizational management of asthma pose a considerable and continuing challenge to healthcare delivery. One element in attempts to meet this challenge is the recognition of appropriate outcome measures to assess progress in tackling the burden of this disease. This study therefore aimed to assess pragmatically the effectiveness of a revised asthma morbidity index in identifying varying patterns of morbidity in U.K. general practices. A postal survey was conducted of 2,762 patients believed to have or have had asthma from the lists of 12 general practices within the Eden Valley in Cumbria, using a questionnaire which combined the revised Jones morbidity index with questions on age, medication and perception of current asthma. Prescribing data were also recovered for 11 of the practices for the quarter within which the postal survey was conducted. Responses were obtained from 2,123 subjects (77%), of whom 1,474 (70%) believed themselves to be currently asthmatic. In this group, 18% reported low morbidity 34% medium morbidity and 48% high morbidity Age and inhaled steroid use were both positively and significantly associated with high morbidity. Those taking inhaled steroids were 1.4 times more likely to report high morbidity than those nottaking steroids. The prescribed corticosteroid/bronchodilator ratio for cost was both negatively and significantly associated with high morbidity. The revised morbidity index is a simple tool of use in the surveillance of asthma in primary care. It identifies spectra of morbidity which vary between practices, which may be of use in assessing the quality of asthma care provided in the community.     

Food Allergy Is Associated With Potentially Fatal Childhood Asthma

Background. Risk factors for potentially fatal childhood asthma are incompletely understood. Objective. To determine whether self-reported food allergy is significantly associated with potentially fatal childhood asthma. Study design. Medical records from 72 patients admitted to a pediatric intensive care unit (PICU) for asthmatic exacerbation were reviewed and compared in a case-control design with 2 randomly selected groups of 108 patients admitted to a regular nursing floor for asthma and 108 ambulatory patients with asthma. Factors evaluated included self-reported food allergy, gender, age, poverty area residence, race/ethnicity, inhaled steroid exposure, tobacco exposure, length of hospital stay, psychologic comorbidity, and season of admission. Results. At least one food allergy was documented for 13% (38/288) of the patients. Egg, peanut, fish/shellfish, milk, and tree nut accounted for 78.6% of all food allergies. Children admitted to the PICU were significantly more likely to report food allergy (p = 0.004) and 3.3 times more likely to report at least one food allergy compared with children admitted to a regular nursing floor, and significantly more likely to report food allergy (p < 0.001) and 7.4 times more likely to report at least one food allergy compared with children seen in the ambulatory setting. Children admitted to either the PICU or the regular nursing floor were significantly more likely be African-American (p < 0.001) and to be younger (p < 0.01) compared with children seen in the ambulatory setting. Conclusions. Self-reported food allergy is an independent risk factor for potentially fatal childhood asthma. Asthmatic children or adolescents with food allergy are a target population for more aggressive asthma management.     

Cost analysis of the use of inhaled corticosteroids in the treatment of asthma: a 1-year follow-up

A retrospective cohort using pharmacy and medical claims was analysed to determine whether the differences in efficacy of various inhaled corticosteroids demonstrated in clinical trials lead to differences in costs of care observed in clinical practice. Subjects that had an ICD-9 (493.XX) code for asthma and a new pharmacy claim for inhaled fluticasone propionate 44 mcg (FP), beclomethasone dipropionate (BDP), triamcinolone acetonide (TAA), budesonide (BUD) or flunisolide (FLU) were identified and followed for 12 months. Annual asthma care charges (pharmacy and medical) over the 12-month observation period were significantly (P < 0.03) higher in patients treated with BDPTAA, BUD and FLU compared to FP, 24%, 27%, 34% and 45% respectively In addition, patients treated with BDPTAA, and FLU were associated with significantly (P < 0.005) higher total healthcare (asthma + non-asthma) charges compared to patients on FP, 53%, 46% and 39% respectively Asthma care and total healthcare charges remained lower for FP after including FP110 mcg and excluding patients who were extreme cost outliers (+/- 2 SD from the mean) in a univariate sensitivity analysis. This analysis supports recent randomized control trials that FP offers a superior efficacy profile at lower asthma care as well as total healthcare charges compared to other inhaled corticosteroids.     

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.     

Exhaled nitric oxide and asthma in young children

Exhaled nitric oxide (eNO) has been used to diagnose asthma in adults and children using either the slow vital capacity method (SVCm) or, in younger children, the tidal breathing method (TBm). Adenosine 5'-monophosphate (AMP) challenge also has been found to be a sensitive and specific test for the diagnosis of asthma. In the present study, we used the AMP provocation concentration that caused wheezing (PCW) to confirm the diagnosis of asthma (PCW < or = 200 mg/mL). We studied 36 children (2-7 years) with mild intermittent asthma, 13 children (3-7 years) with moderate persistent asthma treated with inhaled steroids, 20 nonasthmatic children (2-7 years) with chronic cough and recurrent pneumonia, and 15 healthy children (4-6 years). Expired gas was collected in collection bags by the TBm, and eNO was measured. We evaluated the efficacy of eNO values in diagnosing asthma. The mean eNO level of the mild intermittent asthmatic children (5.6 +/- 0.4 ppb) not receiving inhaled corticosteroids was significantly higher (ANOVA P < 0.0001) than that of the moderate persistent asthmatics who were treated with inhaled steroids, the nonasthmatic children with chronic cough, and the group of healthy children (3.7 +/- 0.6 ppb, P < 0.05; 3.2 +/- 0.3 ppb, P < 0.001; 2.2 +/- 0.2 ppb, P < 0.001, respectively). The points of intersection for sensitivity and specificity curves of eNO to differentiate mild intermittent asthmatics from nonasthmatic children with chronic cough and from healthy children were 77% and 88% for eNO values of 3.8 ppb and 2.9 ppb, respectively. We conclude that eNO collected by the TBm can differentiate steroid-naive young children with intermittent asthma from healthy children, from nonasthmatic children with chronic cough, and from asthmatic children treated with inhaled steroids.     

Food Allergy as a Risk Factor for Asthma Morbidity in Adults

Background. The objective of this study was to evaluate the relationship between food allergy and asthma morbidity in adults. Methods. We interviewed a cohort of persistent asthmatics from an inner-city clinic. Allergies to food were assessed by patient report of convincing symptoms of acute allergic reactions. Outcome variables included health resource utilization and medication use. Results. The prevalence of allergy to fish, peanut, tree-nut, shellfish, and seed allergies were 3%, 3%, 3%, 13%, and 1%. Patients with allergies to > 1 food had increased asthma hospitalizations, ED visits, and use of oral steroids (p < 0.05 for all comparisons). Specifically, allergy to fish was associated with a greater risk of health resource utilization and increased frequency of oral steroid use (p ≤ 0.03 for all comparisons). Conclusions. Self-reported allergy to foods was associated with worse outcomes, suggesting that food allergy may be a risk factor for increased asthma morbidity in adults.     

Differences in asthma diagnosis and medication use in children living in Germany and the Netherlands.

AIM: To compare diagnosis and treatment between German and Dutch children with asthmatic symptoms at the age of 5-6 and 7-8 years, and the use of anti-asthma medication at 7-8 years of age. METHODS: Parents of 4462 children participated in two surveys, in 1995 and 1997. All 465 children identified with current asthmatic symptoms at the age of 5-6 (May 1995) or at 7-8 years of age (May 1997) were sent a third more detailed questionnaire (October 1997). RESULTS: Asthma diagnosis was more prevalent in Dutch children with current asthmatic complaints (50-60%), whereas over 90% of the German children with current asthmatic complaints had been diagnosed with bronchitis. Inhaled beta(2)-agonists were more frequently used by Dutch children compared to German children (67.3% vs. 45.6% p < 0.01) as were inhaled steroids (38.9% vs. 7.0% p < 0.01). Instead, German children more often used sodium cromoglycate or nedocromil as anti-inflammatory medication as compared with Dutch children (42.1% vs. 11.5% p < 0.01). CONCLUSIONS: Differences in diagnosis rates for asthma and bronchitis between German and Dutch children most likely result from differential labelling of complaints, and probably lead to differences in treatment practice, indicating possible undertreatment of German children with inhaled steroids.     

哮喘儿童吸入性糖皮质激素使用情况及用药依从性评价

目的探讨哮喘儿童吸入性糖皮质激素(Inhaled corticosteroids,ICS)使用情况及用药依从性。方法选择2016年1月至2018年1月期间本院儿科住院部和门诊收治的哮喘儿童共350例。采用问卷调查了解哮喘儿童的一般情况下、ICS使用情况和用药依从性,并分析用药依从性差的影响因素。结果350例儿童哮喘病例中,布地奈德、氟替卡松和倍氯卡松的使用率分别为81.14%、10.29%、8.57%。雾化器、压力定量气雾剂和干粉吸入剂的使用率分别为62.29%、27.43%和10.29%。哮喘儿童ICS用药依从性差占74.86%,而用药依从性佳仅占25.14%。儿童哮喘ICS用药依从性差的原因主要包括担心ICS的安全性、家庭经济困难、不配合治疗、自认痊愈而停药和吸入方法不正确等。单因素分析显示,哮喘严重程度、父母受教育程度、掌握ICS吸入装置、家庭经济困难、父母对哮喘认知、父母对医护人员的信任程度与ICS用药依从性具有紧密的关系。多因素logistic回归分析显示,哮喘病情程度、父母受教育程度、父母对哮喘认知程度和父母对医护人员的信任程度越高,儿童哮喘ICS用药依从性越高。结论哮喘儿童ICS的使用以布地奈德雾化吸入为主,但用药依从性与多种因素具有紧密的关系,针对上述因素进行有效干预可有利于提高用药依从性,最终改善治疗效果。     

Transition to Managed Care Impacts Health Care Service Utilization by Children Insured by Medicaid

Purpose. To evaluate the impact of transition to managed care from fee for service on asthma service utilization among Maryland Medicaid insured children. Methods. Healthcare claims from 1997–2000 for children with asthma insured by Maryland Medicaid were extracted and analyzed. Results. Between 1997–2000, inhaled corticosteroid use increased as a proportion of all asthma medications. Outpatient asthma visits increased from 4.2% to 5.9% of all outpatient claims as both asthma-related hospitalizations and emergency department visits decreased. Conclusions. Restructuring of Maryland Medicaid for children from fee for service to managed care was associated with improvement in asthma-related healthcare utilization claims.     

Survey of asthma control in Thailand

OBJECTIVE: The aim of the study was to determine whether asthma management in Thailand is succeeding in achieving the levels of control, specified in national and international asthma guidelines. METHODOLOGY: Adults with asthma in Bangkok, Chiang Mai, Songkhla, and Khon Kaen were interviewed, and we have reported on their asthma severity, morbidity, control, perception of asthma, and healthcare use. RESULTS: A total of 466 asthma sufferers were interviewed. The burden of asthma was high, with 14.8% of respondents being hospitalized for their asthma in the past year. One-quarter of those surveyed had lost workdays as a result of their asthma, and most patients felt that their lifestyle was limited. The majority of respondents had intermittent asthma (62.9%), 10.5% had mild persistent asthma, 17.6% had moderate persistent asthma, and 9.0% had severe persistent asthma; increasing severity was significantly associated with increased emergency healthcare use (P < 0.00001). Asthma sufferers greatly underestimated the severity of their condition. Only 36.0% used reliever medication, and use of inhaled corticosteroids was low at 6.7%. Understanding of the inflammatory basis of asthma was poor. Few patients underwent lung function tests or took peak flow meter readings. CONCLUSIONS: The burden of asthma is high in Thailand, and guidelines are not being followed. Encouraging greater use of inhaled corticosteroids will be an important step towards improving asthma control.
