Abstract
OBJECTIVES Poor symptom appraisal (detection, interpretation and response to symptoms) plays a major role in prolonged prediagnosis interval in various health conditions. Theories and models have been proposed to study the symptom appraisal process but how they could be employed to improve symptom appraisal remains unclear. We therefore aimed to review approaches to improving symptom appraisal in the literature and to develop a theoretical framework that could guide the development of approaches to improving symptom appraisal among individuals in the general population. DESIGN Systematic review. DATA SOURCES Medline, Web of Science, PsycINFO, Embase, CINAHL and Scopus were searched from inception to 30 March 2021. ELIGIBILITY CRITERIA We included original articles in English in which approaches to improve the detection, interpretation or response to symptoms for symptomatic individuals were described. We excluded articles in which approaches were developed to improve symptom appraisal among healthcare professionals. DATA EXTRACTION AND SYNTHESIS A predefined data extraction form was used to extract the development, characteristics and evaluation of approaches to improving symptom appraisal. This formed the basis for the narrative synthesis. RESULTS Of 19 046 publications identified from the literature search, 112 were selected for full-text review and 29 approaches comprising provision of knowledge of symptoms/signs and additional components (eg, symptom self-examination and comparison) for symptom appraisal were included in the synthesis. Less than half (41.4%) of these approaches were developed based on theories/models. Interestingly, despite the variety of theories/models adopted in developing these approaches, the components of these approaches were similar. CONCLUSION Symptom appraisal is an essential process in a patient's journey that can be targeted to facilitate early diagnosis but is largely unstudied. Building on the literature, we proposed a theoretical framework and approaches to improving symptom appraisal. This could facilitate early identification of a variety of health conditions in the general population. TRIAL REGISTRATION NUMBER CRD42021279500.

Abstract
Recognizing the bi-directional relationship between family functioning and child well-being in the context of childhood chronic conditions, researchers have tested family-focused interventions aimed at promoting both child and family well-being through improving the family's condition management capacity. Based on a sample of 70 interventions for families in which there was a child with a chronic physical condition, this analysis examined the nature of family engagement in the interventions. Data were extracted from the intervention reports using a standardized template; conventional content analysis was used to describe family engagement. Interventions varied in focus, structure, and level of family engagement. Investigators most often sought to improve condition control or management, with parent engagement focused on improving capacity to manage the treatment regimen. Few investigators addressed capacity building in the context of family functioning. Recommendations are made for reporting standards for family-focused interventions and for enhancing the family systems grounding of interventions.

Abstract
BACKGROUND Many factors contribute to uncontrolled asthma; negative inhaled corticosteroid (ICS) beliefs and complementary and alternative medicine (CAM) endorsement are 2 that are more prevalent in black compared with white adults. OBJECTIVES This mixed-methods study (1) developed and psychometrically tested a brief self-administered tool with low literacy demands to identify negative ICS beliefs and CAM endorsement and (2) evaluated the clinical utility of the tool as a communication prompt in primary care. METHODS Comprehensive literature reviews and content experts identified candidate items for our instrument that were distributed to 304 subjects for psychometric testing. In the second phase content analysis of 33 audio-recorded primary care visits provided a preliminary evaluation of the instrument's clinical utility. RESULTS Psychometric testing of the instrument identified 17 items representing ICS beliefs (α = .59) and CAM endorsement (α = .68). Test-retest analysis demonstrated a high level of reliability (intraclass correlation coefficient = 0.77 for CAM items and 0.79 for ICS items). We found high rates of CAM endorsement (93%), negative ICS beliefs (68%), and uncontrolled asthma (69%). CAM endorsement was significantly associated with uncontrolled asthma (P = .04). Qualitative data analysis provided preliminary evidence for the instrument's clinical utility in that knowledge of ICS beliefs and CAM endorsement prompted providers to initiate discussions with patients. CONCLUSION Negative ICS beliefs and CAM endorsement were common and associated with uncontrolled asthma. A brief self-administered instrument that identifies beliefs and behaviors that likely undermine ICS adherence might be a leveraging tool to change the content of communications during clinic visits.

Abstract
OBJECTIVE Low adherence with asthma treatment may be associated with suboptimal outcomes and hence create a treatment gap in the real-life setting. The objective of this study was to assess the long-term association between adherence to treatment with fixed-dose fluticasone propionate/salmeterol (FSC) and the risk of exacerbations and health care utilization in patients with asthma. RESEARCH DESIGN AND METHODS Observational single cohort study utilizing the Quebec Health Insurance databases. All patients (age >12 years) with a diagnosis of asthma (ICD9-CM 493.xx) between 2001 and 2010 were entered into the study cohort at the time of their first prescription for FSC at any dose. Follow-up continued to the last known claim or death. Adherence to treatment was ascertained as compliance (medication possession ratio ≥80%) and persistence (absence of treatment gap ≥30 days). MAIN OUTCOME MEASURES Outcomes assessed were exacerbations defined as one of the following: use of oral corticosteroid (OCS), emergency room (ER) visit for asthma or hospitalization for asthma. Asthma related health care resource utilizations ascertained were number of prescription claims for rescue medications, ER visits, hospitalizations, intensive care unit (ICU) stay, intubations, and general practitioner (GP) and respirologist visits. RESULTS A total of 19,126 patients were included in the study. The proportion of compliant and persistent patients were 42.7% and 29.3% respectively. Multivariate logistic regression analyses showed a significantly reduced adjusted odds of exacerbations for compliant (OR = 0.48; 95% CI: 0.44-0.54) and persistent patients (OR = 0.42; 95% CI: 0.38-0.48). Similarly, significantly lower rates of health care utilization were observed for compliant and persistent patients. CONCLUSIONS The results of this large population-based study have shown that increased adherence to treatment with FSC is associated with lower risk for exacerbations, lower rescue medication use and lower health care utilization in asthma patients. Despite the typical limitations of an administrative database study including validity of the diagnosis, the fact that compliance and persistence are calculated based on filled claims which does not guarantee that the patients actually took their medications, and the absence of clinical and laboratory data, the findings have implications for physician and patient awareness of the importance of adherence in the management of asthma.

Abstract
BACKGROUND While guidelines recommend that children with asthma should receive asthma education, it is not known if education delivered in the home is superior to usual care or the same education delivered elsewhere. The home setting allows educators to reach populations (such as the economically disadvantaged) that may experience barriers to care (such as lack of transportation) within a familiar environment. OBJECTIVES To perform a systematic review on educational interventions for asthma delivered in the home to children, caregivers or both, and to determine the effects of such interventions on asthma-related health outcomes. We also planned to make the education interventions accessible to readers by summarising the content and components. SEARCH STRATEGY We searched the Cochrane Airways Group Specialised Register of trials, which includes the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, AMED and PsycINFO, and handsearched respiratory journals and meeting abstracts. We also searched the Education Resources Information Center database (ERIC), reference lists of trials and review articles (last search January 2011). SELECTION CRITERIA We included randomised controlled trials of asthma education delivered in the home to children, their caregivers or both. In the first comparison, eligible control groups were provided usual care or the same education delivered outside of the home. For the second comparison, control groups received a less intensive educational intervention delivered in the home. DATA COLLECTION AND ANALYSIS Two authors independently selected the trials, assessed trial quality and extracted the data. We contacted study authors for additional information. We pooled dichotomous data with fixed-effect odds ratio and continuous data with mean difference (MD) using a fixed-effect where possible. MAIN RESULTS A total of 12 studies involving 2342 children were included. Eleven out of 12 trials were conducted in North America, within urban or suburban settings involving vulnerable populations. The studies were overall of good methodological quality. They differed markedly in terms of age, severity of asthma, context and content of the educational intervention leading to substantial clinical heterogeneity. Due to this clinical heterogeneity, we did not pool results for our primary outcome, the number of patients with exacerbations requiring emergency department (ED) visit. The mean number of exacerbations requiring ED visits per person at six months was not significantly different between the home-based intervention and control groups (N = 2 studies; MD 0.04; 95% confidence interval (CI) -0.20 to 0.27). Only one trial contributed to our other primary outcome, exacerbations requiring a course of oral corticosteroids. Hospital admissions also demonstrated wide variation between trials with significant changes in some trials in both directions. Quality of life improved in both education and control groups over time.A table summarising some of the key components of the education programmes is included in the review. AUTHORS' CONCLUSIONS We found inconsistent evidence for home-based asthma educational interventions compared to standard care, education delivered outside of the home or a less intensive educational intervention delivered at home. Although education remains a key component of managing asthma in children, advocated in numerous guidelines, this review does not contribute further information on the fundamental content and optimum setting for such educational interventions.

Abstract
Although almost one in ten (8.6%) preschool children has been diagnosed with asthma, few asthma management programs are designed for parents of preschool children. The Asthma Basics for Children program addressed this need in 2003-2008 by implementing a multi-layered approach that offered educational activities to center staff, parents, and children and PACE training to physicians in 31 Northern Manhattan daycare centers. Following program participation, 85% of parents reported reducing their child's triggers, 89% said it was easier to talk to their child's physician, and 80% were confident in their ability to manage their child's asthma. Children's any daytime symptoms dropped from 78% to 42%, any nighttime symptoms from 81% to 49%, any daycare absences from 56% to 38%, any asthma-related emergency department (ED) visits from 74% to 47%, and any asthma-related hospitalizations from 24% to 11% (p < .001 for all differences). Outcomes varied by level of exposure. In the Center-Only group (no parent participation), the only reduction was from 19% to 10% (McNemar = 3.77, p = .052) in hospitalizations. Children whose parents participated in the program had significant reductions in daycare absences (62% to 38%, McNemar = 11.1, p < .001), ED visits (72% to 43%, McNemar = 19.2, p < .001), and hospitalizations (24% to 11%, McNemar = 5.54, p = .018). Children whose parents and healthcare provider participated had the greatest improvements with asthma-related daycare absences dropping from 62% to 32% (McNemar = 9.8, p = .001), ED visits from 72% to 37% (McNemar = 14.4, p < .001), and hospitalizations from 35% to 15% (McNemar = 8.33, p = .003). This study demonstrates that a multi-layered approach can improve asthma outcomes among preschoolers with a combination of parent and provider education having the greatest impact.

Abstract
PURPOSE This study aims to investigate the association between social support variables and healthy lifestyle for asthma management among early adolescents (ages 9-14 years). DESIGN AND METHODS Questionnaires were completed by 86 parent-adolescent dyads. RESULTS Healthy lifestyle was associated with social support variables. The association with peer acceptance was stronger among adolescents who received less asthma-specific support from peers. Age was negatively associated with healthy lifestyle, but the association was attenuated after adjustment for asthma-specific peer support. PRACTICE IMPLICATIONS The findings of this study suggest recognizing the developmental change of social support during early adolescence.

Abstract
BACKGROUND Asthma is the most common chronic childhood illness and is a leading cause for paediatric admission to hospital. Asthma management for children results in substantial costs. There is evidence to suggest that hospital admissions could be reduced with effective education for parents and children about asthma and its management. OBJECTIVES To conduct a systematic review of the literature and update the previous review as to whether asthma education leads to improved health outcomes in children who have attended the emergency room for asthma. SEARCH STRATEGY We searched the Cochrane Airways Group Trials Register, including the MEDLINE, EMBASE and CINAHL databases, and reference lists of trials and review articles (last search May 2008). SELECTION CRITERIA We included randomised controlled trials of asthma education for children who had attended the emergency department for asthma, with or without hospitalisation, within the previous 12 months. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data. We contacted study authors for additional information. We pooled dichotomous data with a fixed-effect risk ratio. We used a random-effects risk ratio for sensitivity analysis of heterogenous data. MAIN RESULTS A total of 38 studies involving 7843 children were included. Following educational intervention delivered to children, their parents or both, there was a significantly reduced risk of subsequent emergency department visits (RR 0.73, 95% CI 0.65 to 0.81, N = 3008) and hospital admissions (RR 0.79, 95% CI 0.69 to 0.92, N = 4019) compared with control. There were also fewer unscheduled doctor visits (RR 0.68, 95% CI 0.57 to 0.81, N = 1009). Very few data were available for other outcomes (FEV1, PEF, rescue medication use, quality of life or symptoms) and there was no statistically significant difference between education and control. AUTHORS' CONCLUSIONS Asthma education aimed at children and their carers who present to the emergency department for acute exacerbations can result in lower risk of future emergency department presentation and hospital admission. There remains uncertainty as to the long-term effect of education on other markers of asthma morbidity such as quality of life, symptoms and lung function. It remains unclear as to what type, duration and intensity of educational packages are the most effective in reducing acute care utilisation.

Abstract
PURPOSE OF REVIEW To discuss the unique challenges of managing asthma in young children and to review the literature over the past year with regard to regimen adherence in this relatively understudied population. RECENT FINDINGS Young children and their families face unique challenges in dealing with asthma and these have the potential to affect regimen adherence. They include the time and effort required by asthma-management activities (e.g. nebulizer use), dependency on parents for asthma care, and the limited ability of children to communicate about their symptoms. Five published studies were found for the past year. They covered three areas: adherence assessment (e.g. electronic monitoring versus diary cards), device impact on adherence (e.g. influence of the novelty of medication-delivery device), and adherence interventions (e.g. parental education regarding symptoms). SUMMARY Research suggests that several components need to be considered when designing interventions to improve adherence for young children with asthma: to consider the strain in the caregiver role when developing the treatment regimen, to provide devices that parents and children can use, to monitor adherence with electronic monitoring, and to address parents' concerns and perceptions about treating prodromal symptoms of an asthma exacerbation. Because many parents are hesitant to treat cough symptoms, an additional training component may need to be added to address this concern.

Abstract
BACKGROUND Current labeling practices for allergenic foods like peanut can be inadequate. For future regulatory and industry guidelines, information on no-observed-adverse-effect levels (NOAELs) and eliciting doses (EDs) for allergenic foods is necessary. OBJECTIVE To determine NOAEL and ED in a representative group of peanut-sensitized children, relate these data to history and sensitization, and evaluate the outcome of dietary management. METHODS From an overall eligible group of 96 peanut-sensitized children, a representative group of 27 was evaluated by questionnaires, skin prick test, determination of specific IgE, and double-blind placebo-controlled food challenge (DBPCFC) with peanut according to the international consensus protocol, with 9 doses ranging from 10 microg to 3 g peanut flour. Dietary management was evaluated over a 12-month period. RESULTS Twenty-two children (81%) had a positive DBPCFC. The NOAEL in this group was 1 mg peanut flour, corresponding to 2 mg whole peanut. The ED for subjective symptoms (10 mg to 3 g) was significantly lower than for objective symptoms (100 mg to 3 g; P = .002). Severe reactions occurred only at high doses. EDs were not correlated to previous reactions by history, skin prick test, or specific IgE levels. All patients with a positive DBPCFC were advised to follow a strict diet. During the follow-up period, 10 patients had a less strict diet likely containing traces of peanut. In 3 cases, a mild reaction occurred with food products labeled "may contain peanut." CONCLUSION The NOAEL in a representative group of children with peanut allergy was 2 mg. Dietary compliance in half of this group was inadequate.

Abstract
BACKGROUND Psychosocial and emotional factors are important in childhood asthma. Nevertheless, drug therapy alone continues to be the main treatment. Treatment programmes that include behavioural or psychological interventions have been developed to improve disturbed family relations in the families of children with severe asthma. These approaches have been extended to examine the efficacy of family therapy to treat childhood asthma in a wider group of patients. This review systematically examines these studies. OBJECTIVES Recognition that asthma can be associated with emotional disturbances has led to the investigation of the role of family therapy in reducing the symptoms and impact of asthma in children. The objective of this review was to assess the effects of family therapy as an adjunct to medication for the treatment of asthma in children. SEARCH STRATEGY We searched the Cochrane Airways Group trials register, Psychlit and Psychinfo. Searches are current as of January 2005. SELECTION CRITERIA Randomised trials comparing children undergoing systematic therapy focusing on the family in conjunction with asthma medication, with children taking asthma medication only. DATA COLLECTION AND ANALYSIS Two reviewers assessed the studies for inclusion in the review. MAIN RESULTS Two trials with a total of 55 children were included. It was not possible to combine the findings of these two studies because of differences in outcome measures used. In one study, gas volume, peak expiratory flow rate and daytime wheeze showed improvement in family therapy patients compared to controls. In the other study, there was an improvement in overall clinical assessment and number of functionally impaired days in the patients receiving family therapy. There was no difference in forced expiratory volume or medication use in both studies. AUTHORS' CONCLUSIONS There is some indication that family therapy may be a useful adjunct to medication for children with asthma. This conclusion is limited by small study sizes and lack of standardisation in the choice of outcome measures.
