We investigated the extent to which parents of children with asthma implement recommendations provided by the ED staff.    Method:  We asked questions on asthma triggers, ED care (including education and discharge recommendations), and asthma management strategies used at home, shortly after the ED visit and again at 6 months.    Results:  148 children with asthma were recruited.  32% of children were not on inhaled corticosteroids prior to their ED visit.  80% of parents identified upper respiratory tract infections (URTIs) as the primary trigger for their child’s asthma. No parent received or implemented any specific asthma strategies to reduce the impact of URTIs; 82% of parents did not receive any printed asthma education materials. Most (66%) parents received verbal instructions on how to manage their child’s future asthma exacerbations.  Of those, one-third of families were told to return to the ED. Parents were rarely advised to bring their child to their family doctor in the event of a future exacerbation. At six months, parents continued to use the ED services for asthma exacerbations in their children, despite reporting feeling confident in managing their child’s asthma.    Conclusion: Improvements are urgently needed in developing strategies to manage pediatric asthma exacerbations related to URTIs, communication with parents at discharge in acute care,   4 and utilizing alternate acute care services for parents who continue to rely on EDs for the initial care of mild asthma exacerbations.     5 Introduction   Asthma exacerbations are common in children and frequently result in visits to pediatric or general emergency departments (EDs).<1,2> A recent population-based study from Ontario, Canada noted that nearly 10% of children with asthma visit the ED at least once every two years, with most visits for exacerbations of high acuity.<3> In the United States in 2004, childhood asthma accounted for 640,000 ED visits.<4>   Previous research examining predictors of ED visits for asthma focused on patients’ socio-economic, demographic, and physiological factors associated with such visits. <5–8> These studies identified multiple risk factors for pediatric asthma ED visits and subsequent relapses, including asthma severity, underutilization of inhaled corticosteroids, overuse of beta agonist monotherapy <5,6>, increased age <5>, passive smoke exposure <5> and other environmental pollutants<8>, and ED visits in the prior year.<5,6>  The National Asthma Education and Prevention Program (NAEPP) recommends follow-up care to reduce the risk of relapse.<9> Follow-up with primary care providers after an ED visit is sub-optimal.<10–13> Communicating asthma severity to parents in the ED may improve such rates.<14> In a study of EDs in Ontario, Canada <3> several ED strategies were associated with a reduction in return visits for asthma exacerbations, including the preprinted order forms, consulting a pediatrician during the ED visit, and following clinical practice guidelines. Similarly, we showed that implementation of an ED pediatric asthma clinical pathway, which used evidence-based guidelines and structured teaching, reduced hospitalization and return ED visits for asthma.<15>  These studies focused on broad systems of care to improve management of children with an asthma exacerbation. Less is known about the role of communication between ED staff and   6 parents at the point of care and the impact of communication on the subsequent decisions of parents caring for the child. Educational sessions for parents and children with asthma following ED visits can improve health outcomes and enhance self or parental care of asthma <16> but communication that occurs during an ED visit could also impact future care decisions. Our objectives were to determine: 1) the extent to which parents of children with asthma who receive ED services for acute asthma exacerbation recall and implement recommendations provided by ED staff; 2) the strategies used by these parents to manage and reduce the risk of future exacerbations; and 3) the pattern of utilization of health services of these children following ED visits.  Methods  Design and Setting  We conducted a prospective study of children with asthma who visited a pediatric ED for exacerbations of asthma. We interviewed their parents within two weeks of the child’s ED discharge and again 6 months after the ED visit. This study was conducted at British Columbia’s Children’s Hospital (BCCH) in Vancouver, British Columbia, a 200-bed tertiary care pediatric hospital. Each year the ED at BCCH treats approximately 2,000 children for asthma. Ethical approval for this study was obtained from the University of British Columbia Behavioral Research Ethics Board.   Subject Recruitment We recruited children with a previous diagnosis of asthma who visited the ED for an asthma exacerbation and were 0.5 to 15 years of age. Patients were excluded: if their English   7 skills were not sufficient to answer questions or provide informed consent; if their primary diagnosis in the ED was upper respiratory tract infection (URTI), lower respiratory tract infection, or pneumonia; or if their index ED visit resulted in a hospital admission.  Emergency Management and Chart Review  Each child admitted to the ED received treatment for asthma in the ED according to the BCCH Emergency Management of Asthma Clinical Pathway, <8> which included structured assessment/documentation forms, a plan-of-care flowchart designating therapy, as well as nursing and physician actions in the ED based on severity of exacerbation. Upon arrival to the ED, the triage nurse categorized the asthma severity for each patient (Table 1). Patients who were categorized as ‘critical’ exited the pathway and were not eligible for this study. Using the clinical pathway (Figure 1), children were treated according to their asthma severity. All patients received salbutamol, and children with moderate or severe exacerbations received ipratropium bromide and oral corticosteroids, as specified in the pathway. Patients meeting criteria for discharge were provided with prescriptions and usage instructions for salbutamol, oral corticosteroids, and inhaled corticosteroids. The clinical pathway contained a standardized printed checklist of education on asthma management, including the recommendation to follow up with the child’s primary care physician within 48 hours of the ED visit. Teaching topics included anatomy and physiology, triggers, medications, inhaler technique, and signs and symptoms of respiratory distress. Physicians were trained in the use of the clinical pathway and checklist; however, they were not directly observed in their interactions with families.   8 Telephone Interviews Following discharge from the ED, we conducted telephone interviews with the parents of recruited children 7 to 14 days after their index visit. Using a pilot tested structured questionnaire (Table 2), we collected information regarding asthma history, typical symptoms, medications, burden of asthma on the child and parents, previous ED visits and hospitalizations, sleeping patterns, and common triggers for the child’s asthma exacerbations. We asked questions regarding the teaching that the parents received from ED staff at the time of their visit, including the purpose of each medication, indications and administration technique for each medication, any changes in therapy recommended by the ED staff, and instructions on how the parents should manage the next exacerbation. We further inquired about plans for ongoing asthma management, difficulties the children and parents encountered in managing asthma symptoms, level of confidence in managing asthma, and whether recommendations for medical follow-up were implemented.  At six months, the patients and families were contacted for a second interview. In this interview, participants were questioned regarding ED visits and hospitalizations in the 6 months following the index ED visit, any changes made to the asthma care plan since the first interview, and the level of confidence in managing their child’s asthma.   Statistical Analysis   Patient characteristics are reported as means and standard deviations or proportions, as appropriate. To determine whether our sample of patients was representative of the pediatric asthma population seen in the ED at BCCH during the study period, we compared the demographic features of enrolled children with those of children who previously visited the ED   9 for asthma exacerbation and had a history of at least two episodes of wheeze, asthma-related symptoms, or a previous physician-diagnosis of asthma in the two months preceding study initiation. To assess whether we had captured a sample of children comparable to our larger observed population, we compared patient characteristics of our sample with that of a separate random sample of 33% of all children with BCCH ED visits for asthma during the study months for each of the years 2000, 2001, and 2002 (n = 224).  For each question or group of questions, the percentages of patients whose parents provided responses are reported. Chi-square (χ2) analysis were used to assess the relationships between medication use, health care utilization, and sex. All analyses were conducted with SAS Version 9.1 (SAS Institute, Cary, North Carolina).  Results Patient Characteristics One hundred sixty-four patients were prospectively recruited from the BCCH ED between April 2002 and October 2003. All patients were recruited after ED visits for an exacerbation of their asthma. Ten individuals were subsequently excluded from further study, as they were concurrently enrolled in a separate study on asthma care. Six additional families who had been initially recruited were not subsequently available for the first interview and excluded. Among the remaining 148 subjects (Table 3), most were boys, and the mean age was 5.3 years (standard deviation 3.3 years, range 0.5–15 years). One child less than 1 year old was inadvertently recruited, but inclusion of this child’s data did not alter the study results.  There were no significant differences in sex, age distribution, asthma severity, and admission to hospital between our recruited patients and children randomly obtained from the   10 hospital database (p > 0.05), indicating that our sample was similar to pediatric asthma patients who typically visit the BCCH ED (Table 3).  Burden of Asthma and Medication Management Forty-four percent of parents reported their child having asthma for one to three years. Twenty-nine percent of the children had a diagnosis of asthma for more than three years. In general, these children regularly obtained asthma care from hospital services, 43% had been to the ED for an asthma exacerbation three or more times in the past year, and 35% had been admitted to hospital over the last year. There were no significant gender differences in prior medication use or prior ED visits.  The majority of the patients (n = 104; 70%) had at least three symptomatic months in a year, and in a typical symptomatic month, forty one children (28%) had symptoms for at least seven days. Of the 101 patients who attended school or other extracurricular activities, 61 children (60%) missed at least one day and 13 children (13%) missed at least six days per month due to asthma. Sleep was disrupted. During an asthma exacerbation, 84 children (57%) woke up at least once a week due to asthma symptoms, and 31 children (21%) woke up at least four times per week.   Thirty-four children (23%) were not using any asthma-related medication prior to their index ED visit.  Of the 114 children who were using asthma medications, 48 children (42%) were not using inhaled corticosteroids.   11 Characteristics of the Index Visit Triggers. With respect to triggers of the asthma exacerbation that led to their child’s index visit to the ED, 119 families (80%) reported that an upper respiratory tract infection was the primary trigger of their child’s exacerbation at the index visit. The parents of 10 children (7%) identified environmental triggers such as dust, while seven parents (5%) identified exercise as the main triggers for their child. Remaining triggers reported were pet dander, smoke, and emotional stressors.   Discharge Treatments. Fifty-one percent of parents reported that they had received a prescription for oral corticosteroids at discharge. Boys were more likely to be discharged with a prescription for oral corticosteroids compared to girls (odds ratio 3.50, 95% confidence interval 1.70, 7.20; p < 0.0005).  While 62 children (42%) had not been receiving inhaled corticosteroids at the time of the index visit, 36 children (24%) remained without inhaled steroids at discharge from the ED, with no significant difference noted between girls and boys (p = 0.25). Instructions at Discharge. Most parents did not recall being given any information regarding their child’s asthma medications or use of inhaler devices (Table 4). Furthermore, most parents (82%) did not recall being provided with any asthma-related printed reading materials to review at home. Parents of 94 children (65%) reported being instructed to have a follow-up appointment with their family doctor, specialist, or clinic physician after the index exacerbation.   With respect to the management of future exacerbations, 98 families (66%) reported receiving verbal instructions from ED staff on how to manage their child's future episodes of acute asthma (Figure 2). Of those parents, 65 families (66%) were instructed to increase the frequency and/or dosage of inhaled medications, 26 families (27%) were told to return to the ED,   12 and seven families (7%) were told to see their family physician in the event of a future exacerbation.   Parents’ Care Decisions Post-Discharge  Sixty-five percent of parents were instructed to visit their family doctor with their child for a follow-up appointment after the index visit. Of these, 29 parents (30%) did not attend that appointment. The main reason for non-attendance was that they perceived their child to be well and the parents felt a follow-up appointment was unnecessary. Other reasons for non-attendance were the inconvenience of a follow-up appointment and the absence of a primary care doctor. At the first interview, 56% percent of parents planned to make or had already made changes to their child’s home environment. Virtually all changes described by parents included reducing exposure to dust, by replacing carpets with hardwood floors, changing bed covers and mattresses, removing stuffed animals, and increasing the frequency of dusting and vacuuming. Parents did not report any planned strategies to reduce the impact of URTIs on their child’s asthma. No parents indicated that they would initiate or alter the child’s regimen of treatment with corticosteroid medication at the onset of symptoms of URTI.  Parental Confidence in Managing Future Exacerbations Eighty percent of parents reported feeling confident to manage their child’s future asthma exacerbations at home. Among those who did not feel confident, three main themes emerged: 1) their child had recently received an asthma diagnosis and the parents did not feel they possessed sufficient experience to handle an exacerbation; 2) parents felt they lacked adequate specific   13 information regarding the treatment of an exacerbation; and 3) parents expressed feeling uneasy or nervous about the responsibility of treating a child who might develop respiratory distress.   Follow-up Interview   Of the initial 148 patients, parents of 133 children were available for a follow-up interview. In the six-month interval, 52 (40%) patients had attended the ED at least once more for an asthma exacerbation, 18% had two or more visits, and 9% had three or more visits, with URTIs reported as the major trigger. There was no change in the planned strategies for asthma care compared to the first interview.   Discussion In this prospective study, most parents of children with asthma recall and implement only a few recommendations that are provided by medical staff at the time of visits for acute care. Recall was poorest about asthma medications, use of inhaler devices, and receiving any asthma-related reading material. Parents remembered more frequently that ED staff provided them with some, although highly variable, directions to manage future exacerbations of their child’s asthma. Demonstrating the proper use of inhalers was either not recalled by parents or not done in the ED.  We cannot determine whether these problem result from a lack of parental recall and/or a lack of effective education provided in the ED. The ED in this study used a clinical pathway with a checklist of topics to be covered. Although this pathway ‘cues’ physicians and staff to provide standardized care and education, this likely does not occur for every patient. Parents may receive the recommended education and still fail to recall the key points after the visit. A multi-  14 component system of follow-up care that relies less on brief interactions with patients in the ED is essential. Effective mechanisms for delivering asthma education and improving  follow-up care include written action plans,<17,18> video-based education,<19> and post-discharge text messaging. <20> Additional strategies could include automatic reminder phone calls to see the family physician, education from the pharmacist, access to online resources, and immediate discharge notes sent to the family physician to alert them of the ED visit.   We found that while most parents recognize URTIs to be the primary trigger of asthma exacerbations in their child, most home strategies reported by parents for improving asthma control were focused on environmental changes such as dust control. Preventing most URTIs in children with asthma is a formidable challenge, given their exposure to respiratory viruses in school and community settings. A more effective approach may be helping parents to better respond to their child’s symptoms of a URTI, to reduce the likelihood of the URTI progressing to a serious asthma exacerbation warranting an ED visit. The NAEPP guidelines <9> for asthma and the Global Initiative for Asthma (GINA) guidelines <21> recommend that children with asthma and a history of severe exacerbations who develop any symptoms of a URTI immediately begin a course of corticosteroids to reduce the likelihood of a severe exacerbation. In the present work, consistent with our clinical experience, this recommendation was not routinely followed. Both health care providers and parents need to implement strategies that address the impact of URTIs on pediatric asthma exacerbations.  Although they expressed confidence in managing their child’s asthma exacerbation, parents continued to attend the ED. Many factors likely contribute to this pattern of care. Parents may primarily respond to severe, more immediate exacerbation symptoms, and defer medical visits whenever they perceive their child to be well. Regular use of ED services might also   15 become ‘normalized’ for some parents. Emergency staff may reinforce this pattern, given our observation that many participants were advised to return to the ED for future exacerbations. Strategies to reduce frequent ED use should focus on providing families with reasonable alternatives to ED care for mild to moderate exacerbations.  Several limitations are apparent in our study design. Our findings may not be necessarily generalizable to different settings or jurisdictions with different health care delivery or population characteristics. In addition, patient- and parent-reported outcomes are subject to recall bias. Such bias was limited in part by conducting our first interview shortly after the index visit, using structured interviewing methods, and evaluating medical records. Other factors that might influence parental recall were not assessed and may include physician experience, time of visit, case volume in the ED, parental fatigue, and information provided by other care providers.  Nevertheless, parents’ retention of key discharge instructions and implementation of asthma care to prevent relapses is poor and reinforces the need to improve at numerous levels.   Conclusions  Parents of children with asthmatic exacerbations recall and implement only a few recommendations from medical staff following visits for asthma care in the ED of a pediatric tertiary care center. Limitations in asthma education and verbal communication in acute care settings may be amenable to numerous interventions and enhancements, which require further study to define the strategies that improve the post-discharge care of children with asthma who frequently visit the ED.  Such interventions could target the prevention and management of asthma exacerbations triggered by URTI. Other targets requiring investigation may be more subtle or complex, including the elements of communication and the relationships between   16 parents, primary care physicians and ED staff caring for children with asthma, as well as the models of care.
