A successful effort to improve asthma care outcome in an inner-city emergency department.

The purpose of this study was to improve asthma care and outcome in an inner-city emergency department. Consecutive adult patients (19,802) presenting with the diagnosis of acute asthma exacerbation to an inner-city municipal hospital emergency department, between July 1991 and December 1993, were prospectively evaluated. These patients were compared to a historical control group of 7923 consecutive asthma emergency department patients presenting in the year prior to our intervention. An asthma treatment guideline was implemented through a continuous quality improvement process. Asthma relapse rate and admission rate were obtained before and after the guidelines were instituted. Data after interventions were also prospectively compared to asthma outcomes at all other New York City municipal hospital emergency departments. After intervention, mean monthly asthma relapse rates showed a significant reduction from 12.18% to 7.83% (p < 0.001). A similar decrease was also noted in the monthly asthma admission rate, from 4.85 to 3.90 per 100 emergency department visits (p < 0.05). Asthma treatment guidelines along with continuous quality improvement techniques can significantly improve the outcome of inner-city emergency department asthma patients.     

Predictors of prior asthma specialist care among pediatric patients seen in the emergency department for asthma

Background: Asthma guidelines recommend specialist care for patients experiencing poor asthma outcomes during emergency department (ED) visits. The prevalence and predictors of asthma specialist care among an ED population seeking pediatric asthma care are unknown. Objective: To examine, in an ED population, factors associated with prior asthma specialist use based on parental reports of prior asthma morbidity and asthma care. Methods: Parents of children ages 0 to 17?years seeking ED asthma care were surveyed regarding socio-demographics, asthma morbidity, asthma management and current asthma specialist care status. We compared prior asthma care and morbidity between those currently cared for by an asthma specialist versus not. Multivariable logistic regression models to predict factors associated with asthma specialist use were adjusted for parent education and insurance type. Results: Of 150 children (62% boys, mean age 4.7?years, 69% Hispanic), 22% reported asthma specialist care, 75% did not see a specialist and for 3% specialist status was unknown. Care was worse for those not seeing a specialist, including under-use of controller medications (24% vs. 64%, p?<?0.001) and asthma action plans (20% vs. 62%, p?<?0.001). Multivariable logistic regression revealed that lack of recommendation by the primary care physician reduced the odds of specialist care (OR 0.01, 95% CI <0.01, 0.05, p?<?0.001). Conclusions: Asthma specialist care was infrequent among this pediatric ED population, consistent with the sub-optimal chronic asthma care we observed. Prospective trials should further investigate if systematic referral to asthma specialists during/after an ED encounter would improve asthma outcomes.     

A randomized trial of a self-regulation intervention for women with asthma

BACKGROUND: Women with asthma have greater mortality and morbidity than men in the United States. To date, there has been no rigorous evaluation of an intervention focused on the particular problems in asthma management faced by women. This study was a randomized clinical trial of a self-regulation, telephone counseling intervention emphasizing women's concerns, and sex and gender role factors in their management of asthma. METHODS: A total of 808 women with diagnosed asthma were randomly assigned to the intervention group or a usual-care control group, including conventional asthma education. Interviews and medical record data were collected to assess psychosocial factors, and the behavioral factors of functioning, quality of life, symptoms, and health-care use at baseline and the subsequent 1 year. Generalized estimating equations, identity link, logit link, and log link were employed to analyze the data. RESULTS: Compared to control subjects, the women receiving treatment had greater annual reductions in the average number of nights with asthma symptoms (p = 0.04), days of missed work/school (p = 0.03), emergency department visits (p = 0.04), unscheduled office visits (p = 0.01), and scheduled office visits (p = 0.04). They had greater recognition of asthma symptoms during the menstrual cycle (p = 0.0003), had decreased asthma symptoms with sexual activity (p = 0.008), and had greater improvement in quality of life (p = 0.0005), self-regulation (p = 0.03), and self-confidence to manage asthma (p = 0.001). CONCLUSION: The intervention improved women's clinical status, functioning, quality of life, and health-care use. A program with a focus on asthma management problems particular to women can significantly assist female asthma patients.     

The Child Asthma Link Line: A Coalition-initiated,Telephone-based,Care Coordination Intervention for Childhood Asthma

Background. Childhood asthma is a complex chronic disease that poses significant challenges regarding management, and there is evidence of disparities in care. Many medical, psychosocial, and health system factors contribute to recognized poor control of this most prevalent illness among children, with resultant excessive use of emergency departments and hospitalizations for care. Recent national guidelines emphasize the need for community-based initiatives to address these critical issues. To address health system fragmentation and impact asthma outcomes, the Philadelphia Allies Against Asthma coalition developed and implemented the Child Asthma Link Line, a telephone-based care coordination and system integration program, which has been in operation since 2001. This study evaluates the effectiveness of the Child Asthma Link Line integration model to improve asthma management by measuring utilization markers of morbidity. Methods. Medicaid Managed Care Organization claims data for 59 children who received the Link Line intervention in 2003 are compared to a matched sample of 236 children who did not receive the Link Line intervention. Children in the two study groups are ages 3 through 12 years and matched on 2003 emergency department visits, age, gender, and race/ethnicity. Primary outcome variables analyzed in this study are emergency department visits, hospitalizations, and office visit claims from the follow-up year (2004). Results. Link Line intervention children were significantly less likely to have follow-up hospitalizations than matched sample children (p = .02). Children enrolled in the Link Line were also more likely to attend outpatient office visits in the follow-up year (p = .045). In addition, Link Line children with multiple emergency department visits in 2003 were significantly less likely to have an emergency department visit in 2004 (p = .046). Conclusion. This coalition-developed, telephone-based, system-level intervention had a significant impact on childhood asthma morbidity as measured by utilization endpoints of follow-up hospitalizations and emergency department visits. Telephone-based care coordination and service integration may be a viable and economic way to impact childhood asthma and other chronic diseases.     

Asthma Treatment Protocols in the Emergency Department: Are They Effective?

Management of asthma in emergency departments (ED) has been well documented to be deficient over many years, despite national and international guidelines. This review summarizes the effect of ED protocols aimed at improving the assessment and treatment of asthma in the ED. We performed a PubMed search of the English literature for ED asthma protocols published from 1986 to 2006 and identified 11 studies. Protocols were effective in improving at least some areas of management, including use of appropriate patient assessment, drug therapy per national guidelines, and patient education. A small number of protocols with the specific aims of reducing the length of stay in the ED as well as rates of hospital admission and return visits were effective. Persistent education of ED staff regarding protocols based on current management guidelines and adoption of easy-to-use forms can facilitate improved care of patients with asthma in the ED.

A controlled retrospective pilot study of an 'at-risk asthma register' in primary care.

BACKGROUND: There are few reports of primary care initiatives designed to improve management of asthma patients who are at risk of adverse outcomes. AIM: To assess the impact on emergency treatments, service use, and costs, of introducing an at-risk asthma register in a general practice surgery. METHODS: Asthma patients demonstrating characteristics associated with adverse outcomes were added to an at-risk register. Tags were placed in patients' records and practice staff were trained to ensure their appropriate recognition and management. Data were retrospectively extracted from the notes of 26 identified at-risk patients, as well as 26 age-, sex-, and treatment-matched controls with asthma, for one year before and after the introduction of the register. Implementation and service use costs were estimated. RESULTS: Before introduction of the register, more 'at-risk' than control patients were hospitalised (3 vs. 0), attended the accident and emergency (A&E) department (1 vs. 0), and were nebulised (4 vs. 0), for asthma. Significantly higher numbers also used out-of-hours services, received oral steroids, attended their general practitioner (GP), and failed to attend scheduled clinics for asthma (all p<0.025). After introduction of the register, no at-risk patients were admitted or attended A&E. Although differences in the numbers receiving oral steroids remained (p = 0.05), other differences disappeared. There were notably greater reductions in overall numbers of admissions, out-of-hours attendances, GP attendances, courses of steroids, and total costs associated with service use, amongst 'at-risk' as compared to control patients. CONCLUSIONS: An at-risk asthma register is a low cost initiative warranting further evaluation, since it may facilitate appropriate service use in a vulnerable and costly patient group.     

Near-fatal asthma: a population-based study of risk factors

BACKGROUND: The study of near-fatal asthma (NFA) may provide a means to further our understanding of fatal asthma. Studies of NFA often are derived from a single ICU rather than from a defined population. We therefore aimed to identify factors distinguishing NFA patients (cases) from those persons treated in an emergency department (ED) [ED control subjects] and in the community (community control subjects [CCs]). METHODS: This was a population-based case-control study conducted over 20 months of 45 NFA patients (age range, 5 to 50 years), 197 ED control subjects treated in an ED, and 303 CCs, all of whom were residents of Alberta. RESULTS: The age distribution was similar between NFA patients and control subjects, with the majority being < 22 years of age (NFA patients, 68.9%; ED control subjects, 71.3%; CCs, 60.7%). Those patients with NFA were significantly more likely to have received a diagnosis before 5 years of age (66.6%), compared to ED control subjects (39.6%) and CCs (28.7%). The NFA group was significantly more likely to report moderate-to-severe disease and more frequent symptoms than the other groups. Therapy with bronchodilators was used most frequently by the NFA group compared to the ED control subjects and CCs (p < 0.001), as was therapy with inhaled steroids (p < 0.001) and oral steroids (p < 0.001). NFA patients had higher scores for vulnerability and were most likely to admit to stress as an asthma trigger. All groups had high exposure to cigarette smoke and pets. CONCLUSION: NFA patients have many modifiable risk factors and many similarities to ED control subjects and CCs with asthma. General measures to improve asthma control and awareness of risks are required in all groups.     

Impact of a multidisciplinary day program on disease and healthcare costs in children and adolescents with severe asthma: a two-year follow-up study

For patients whose asthma remains in poor control necessitating high utilization of medical services, a referral to a specialized "center of excellence" is often considered. A decade ago, we evaluated our pediatric asthma program of long-term hospitalization (median stay of 75 days) and found significant decreases in subjects' medical utilization following this intervention. In an effort to contain treatment costs, the former program was markedly altered to one of abbreviated stay with emphasis on family management of asthma. The purpose of the present study was to determine the outcome of children treated in the revised program with regard to disease severity, quality of life, and subsequent utilization of medical resources. Children with severe asthma who were admitted to the program and fulfilled study criteria were consecutively enrolled. Data was obtained concerning disease characteristics, treatment, and quality of life at admission, and at 1 and 2 years following discharge. Medical records for the year prior to program admission and for the 2 years following discharge were coded for medical care encounters. Ninety-eight children, aged 9 months to 18 years (mean age, 10.9 years), were enrolled. They participated in the program for a mean of 15.6 ( +/- 8 SD), median of 15.0, and range of 2-51 treatment days. The group showed significant improvement (P < 0.0001) from admission to 1- and 2-year follow-up in median corticosteroid use, asthma functional severity, perceived competence in asthma management, and quality of life for both caregiver and child. Medical record data showed significant improvement (P < 0.0001) at both 1- and 2-year follow-up in median number of corticosteroid bursts, emergency department visits, hospital days, and overall utilization of medical care encounters. A median total medical encounter cost/patient of $16,250 ($6,972-$25,714 interquartile range (IQR)) for the year prior to program participation was reduced to $1,902 ($505-$6,524 IQR) at 1-year and $690 ($185-$3,550 IQR) at 2- year follow-up (P < 0.0001). We conclude that multidisciplinary care in a short-term, outpatient, day treatment program can significantly contribute to improvement in asthma severity, quality of life, and reduction in healthcare costs.     

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.     

Medical audit on asthma in an emergency department

BackgroundTo determine the management of acute bronchial asthma in an adult emergency department.MethodsA retrospective medical audit of 46 consecutive adult patients with acute asthma exacerbations was performed. We collected information from 48 episodes of acute asthma over a 5-month period.Using classical audit methodology, four indicators were examined: severity evaluation, diagnostic tests, specific treatment, and discharge treatment plans.ResultsThe least recorded severity indicators were respiratory rate (27 %), heart rate (50 %) and peak expiratory flow (20 %). Heart and respiratory auscultation were recorded in all patients and oxygen saturation was recorded in 93 %. Laboratory blood test and chest radiograph were performed in all patients. Arterial blood gas was tested in 57 %, electrocardiography in 17 %, and coagulation in 39%. No treatment was provided in 12% of patients. Bronchodilator medications were administered in all treated patients and oxygen was prescribed in 60 %. Systemic corticosteroids (methylprednisolone or hydrocortisone) were administered in 80 % of treated patients. Seventeen percent of patients were discharged from hospital with no change to their usual treatment.ConclusionsThe following weak points were identified: 1) Severity assessment is inadequate, 2) use of diagnostic tests is excessive, 3) patients discharged to home with no treatment plan. Opportunities for improvement consisted of: 1) greater availability of peak expiratory flow meters, 2) individualized use of diagnostic tests, and 3) management protocols.     

Body mass index and asthma severity among adults presenting to the emergency department

STUDY OBJECTIVES: Among adults presenting to the emergency department (ED) with acute asthma, we sought to determine the prevalence of obesity, and the relation of body mass index (BMI) to asthma severity in this high-risk population. DESIGN: Multicenter, prospective cohort study. SETTING: Twenty-six North American EDs. PARTICIPANTS: Five hundred seventy-two patients aged 18 to 54 years presenting with acute asthma. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: A standardized interview assessed demographic characteristics, asthma history, and details of the current asthma exacerbation. Data on ED medical management and disposition were obtained by chart review. Three of four asthmatic patients were either overweight (BMI, 25 to 29.9; 30%) or obese (BMI, > or =30; 44%). Normal weight/underweight, overweight, and obese patients did not differ on several markers of chronic asthma severity; obese subjects tended to rate symptoms more severely and to use more inhaled beta-agonists in the 6 h hours prior to ED presentation despite a significantly higher initial percentage of predicted peak expiratory flow (PEF) [44%, 45%, and 51%, respectively; p < 0.05]. The three BMI groups responded similarly to acute therapy in the ED, with all groups demonstrating reversible airway obstruction. The sex distribution by BMI group differed markedly (p < 0.001), with women less often overweight (40% vs 24%) and more often obese (30% vs 52%). Since women were more likely have a higher initial PEF (45% vs 53%, p < 0.001), we stratified by sex to further examine the relation of BMI to asthma severity. The observed BMI-asthma associations were due largely, but not entirely, to confounding by sex. CONCLUSIONS: Despite lingering concerns about the veracity of "asthma" among obese individuals, asthma exacerbations among obese and nonobese adults were remarkably similar. Potential differences (eg, in symptom perception, use of inhaled beta-agonists before ED presentation, initial PEF rate) were due, in large part, to confounding by sex.     

The effect of a pediatric asthma management program provided by respiratory therapists on patient outcomes and cost

OBJECTIVE: The objective was to determine whether a pediatric asthma disease management program (ADMP) provided by respiratory therapists can improve patient outcomes and reduce cost. DESIGN: This was a pre-and post-intervention observational study. METHODS: Hospitalizations, non-intensive care unit (ICU) hospital days, ICU days, emergency department visits, doctor's office visits, school days missed, and associated costs were collected on 18 children with moderate to severe asthma, ages 3 to 18 years, 12 months before and after implementation of the ADMP. The ADMP consisted of eight home visits for assessment, environmental review, and patient education. RESULTS: There were significant reductions (P < .05) in hospitalizations, hospitalization cost, ICU days, non-ICU days, length of stay, emergency department visits and cost, physician office visits and cost, and school days missed. CONCLUSIONS: A pediatric in-home ADMP provided by respiratory therapists can improve outcomes and reduce cost in patients with moderate to severe asthma.     

A comparison of albuterol administered by metered-dose inhaler and spacer with albuterol by nebulizer in adults presenting to an urban emergency department with acute asthma

STUDY OBJECTIVES: To determine the efficacy of albuterol by metered-dose inhaler (MDI) and spacer compared to a nebulizer. DESIGN: A prospective, open-label study. SETTING: Large urban emergency department (ED). PATIENTS: All consecutive adult asthma patients over a 2.5-year period. INTERVENTIONS: ED personnel used a standardized treatment algorithm, which included albuterol administered by nebulization, for patients presenting to the ED during the first 12 months of the study. The treatment algorithm then was switched to one that utilized albuterol administered by MDI/spacer as the primary mode of delivery for the following 18 months. As part of the conversion to MDI/spacer, ED staff counseled patients on self-management and supplied patients with a peak flowmeter, an MDI/spacer, and an inhaled steroid for home use. MEASUREMENTS: Pulmonary function, clinical outcome, laboratory data, and financial data were assembled and analyzed from 2,342 ED visits and 1,420 patients. RESULTS: While there was no significant difference in hospital admission rates between patients in the MDI/spacer group and the nebulizer group (13.2% and 14.6%, respectively), there was a statistically greater improvement in peak flow rates in the MDI/spacer group (126.8 vs 111.9 L/min, respectively; p = 0.002). The MDI/spacer group also spent significantly less time in the ED (163.6 and 175 min, respectively; p = 0.007), had a lower total albuterol dose (1,125 microg and 6,700 microg, respectively; p < 0.001), and showed a greater improvement in arterial oxygen saturation (p = 0.043). Relapse rates at 14 and 21 days were significantly lower (p < 0.01 and p < 0.05, respectively) among patients treated with the MDI/spacer and were associated with asthma education and the provision of a peak flowmeter, a spacer, and an inhaled corticosteroid for patients' home use. CONCLUSIONS: Albuterol administered by MDI/spacer is an efficacious and cost-effective alternative to nebulization in adults with acute asthma who present at a large urban ED.     

Preventing Emergency Department Visits and Hospitalizations for Asthma by Use of Oral Corticosteroids at Home: Are We Adhering to National Guidelines?

Background: Oral corticosteroids (OCS) in the home management of asthma exacerbations have been recommended in the NIH/NHLBI guidelines since 1991. As a routine component of written action plans, OCS treatment at home is associated with reduced emergency department (ED) visits and hospitalizations as well as decreased mortality. Methods: A literature search of English language journals from 1991 to 2009 was performed using several databases, including PubMed, EMBASE, and SCOPUS. We assessed studies that evaluated adherence to national guidelines for home management of asthma exacerbations. Results: Our review of the literature found that several studies reveal that a small percentage (<3–26%) of patients are receiving OCS at home to manage asthma exacerbations prior to an ED visit. Additional studies were found showing very low use of written action plans, strongly suggesting lack of OCS for home management of asthma exacerbations. Conclusions: Despite evidence of reduced ED visits and hospitalizations and the recommendations of national and international guidelines, the home use of OCS in managing asthma exacerbations remains unacceptably low. New strategies are needed to ensure home use of OCS as part of written action plans to prevent ED visits and hospitalizations for asthma exacerbations.     

Effect of treating allergic rhinitis with corticosteroids in patients with mild-to-moderate persistent asthma

STUDY OBJECTIVES: Rhinitis and asthma are considered to be synchronic or sequential forms of the same allergic syndrome. Treating the inflammation associated with allergic rhinitis influences the control of asthma. However, few studies have investigated the effect of treating perennial rhinitis on persistent asthma and vice versa. We determined the effects of inhaled or topical nasal beclomethasone dipropionate (BDP) administered separately or in combination on the control of asthma and bronchial hyperresponsiveness (BHR) in patients with the rhinitis/asthma association. DESIGN: A double-blind, parallel, three-group study. SETTING: Outpatient clinic of Pulmonary Division/Heart Institute (InCor) and the Division of General Internal Medicine, University of Sao Paulo Medical School, Sao Paulo, Brazil. PATIENTS: Seventy-four patients with mild-to-moderate asthma and allergic rhinitis (median age, 25 years). INTERVENTIONS: Patients received nasal or inhaled BDP separately or in combination for 16 weeks after a 2-week placebo run-in period. MEASUREMENTS AND RESULTS: Nasal and pulmonary symptoms, as well as pulmonary function and BHR, were compared among the three groups after 4 weeks and 16 weeks of treatment. Patients in all three groups demonstrated a progressive and significant decrease in nasal and pulmonary symptoms, which started after 4 weeks (p < 0.05) and continued through the end of treatment (p < 0.001). Clinical improvement was similar and parallel in the three groups. Asthma-related morbidity, evaluated by quantifying absence from work, emergency department visits, and nighttime awakenings, also decreased in the three groups (p < 0.05). CONCLUSIONS: Failure to consider treatment of rhinitis as essential to asthma management might impair clinical control of asthma. Furthermore, these data suggest that asthma and rhinitis in some patients can be controlled by the exclusive use of nasal medication.     

The cost and effectiveness of an education program for adults who have asthma

Study objective:To determine whether a self-management training program decreases emergency department visits and reduces costs for patients with asthma. Design:Randomized controlled trial of an educational program. Setting:Two sites — an urban emergency room and a suburban emergency room. Patients:241 asthma patients between the ages of 18 and 70 years. Of the 119 patients in the intervention group and the 122 in the control group, 185 (76%) were available for follow-up. Intervention:All patients seen in the emergency departments were given usual medical care and follow-up. Patients in the intervention group were asked to attend three educational sessions on asthma conducted by a specially trained RN. The program stressed importance of medication compliance, methods to control and prevent attacks, effects of drugs and rationale for their use, relaxation exercises, and smoking cessation. Measurement and main results:All patients received telephone interviews four, eight, and 12 months after entry into the study. Reports based on hospital admissions and emergency room utilization were verified by billing records. Three patients died during the study, none from asthma-related problems. The intervention group had significantly fewer asthma-related emergency visits (16 visits per 100 persons) than did the control group (39 per 100 persons); p=0.0005 for the 12 months of follow-up. The effect of the intervention on asthma-related emergency department visits was strongest during the initial four months postintervention (68 per 100 persons versus 220 per 100 persons, p=0.003). The financial analysis showed that the $85/person cost for the educational sessions was offset by the $628/person reduction in emergency room charges. Conclusion:Education enables patients with asthma to decrease utilization of emergency services.     

Asthma management and control in the United States: results of the 2009 Asthma Insight and Management survey

Past asthma surveys have shown suboptimal management and control of asthma in the United States. No major survey of asthma management has been conducted since the Third Expert Panel Report for the National Asthma Education and Prevention Program (NAEPP) guidelines on diagnosis and treatment of asthma (August 2007). This study was designed to report asthma management and control results from the Asthma Insight and Management survey of U.S. patients and physicians. A telephone-based survey was conducted during 2009 in 2500 patients with asthma, aged ≥12 years, and 309 physicians (104 allergists, 54 pulmonologists, 101 family practitioners, and 50 internists). Patients' asthma control perceptions (71% "completely controlled" or "well controlled") were inconsistent with their NAEPP control level as determined by self-reported symptoms (29% well controlled). Patients and physicians had low expectations for effective asthma management; patients considered asthma well managed if rescue medication was used three times per week (46%), urgent care visits occurred twice per year (67%), or emergency department visits occurred once per year (60%). Asthma-related syncope, seizure, intensive care unit admission, and intubation were associated with uncontrolled asthma based on NAEPP guidelines. Respiratory specialists (allergists/pulmonologists) implemented asthma management recommendations more than other physicians surveyed. However, only 22% of patients visited a specialist for usual asthma care and 48% had never visited a specialist. Despite detailed NAEPP guidance, asthma management and control in U.S. patients is unsatisfactory. Improved asthma control assessment (impairment and risk) and implementation of NAEPP management recommendations are needed to improve asthma control and outcomes.     

Successful school-based intervention for inner-city children with persistent asthma.

OBJECTIVE: Because children attend school daily, school-based interventions for children with persistent asthma could provide effective disease management for inner-city asthmatic children. The Kunsberg School in Denver, Colorado, enrolls children with chronic diseases, including asthma, into a daily program of school-based disease management. This study sought to determine the impact of the Kunsberg program on asthma utilization. METHODS: Children attending Kunsberg (n=18) who received primary care at Denver Health were compared with a group of matched control children who also received primary care at Denver Health, but did not attend Kunsberg (n=36). Asthma-related utilization for an average of 2.9 years before and after Kunsberg enrollment was assessed. RESULTS: The 18 Kunsberg and 36 control subjects were mostly minority children in low-income families, without significant demographic differences between groups. Compared with controls, the Kunsberg cohort experienced fewer hospitalizations (0.5 vs. 0.9 hospitalizations/subject/ year, p=0.05), fewer emergency department (ED) visits (1.4 vs. 2.8 ED visits/ subject/year, p=0.04), and fewer follow-up visits for asthma (3.7 vs. 5.0 visits/subject/ year, p=0.01) in the time period (mean 2.9 years; range 1-6 years) following the intervention. Hospital- and clinic-based asthma utilization costs decreased 80% following enrollment in the school (8122 dollars/year to 1588 dollars/year per child), compared to a 19% decrease in the control group. Among the Kunsberg children with hospitalizations prior to school enrollment (n=8), hospital days decreased from 3.5 days to 0.1 days annually (p<0.01), ED visits decreased from 2.1 to 0.6 visits annually (p=0.02), and follow-up visits decreased from 6.8 to 2.1 visits annually (p=0.02). As part of their school program, 89% of Kunsberg enrollees received inhaled corticosteroids daily on a monitored basis while at school. Conclusions: The Kunsberg school program improved asthma control and reduced disease severity for at-risk inner-city asthmatic children, leading to cost reduction for asthma management. Directly observed controller therapy at school can be an important component of a school-based program for children with chronic conditions.
