The health and psychosocial functioning of caregivers of children with neurodevelopmental disorders

Purpose. Children with neurodevelopmental disorders (Neuro) pose complex parenting challenges, particularly if the condition co-occurs with behaviour problems. Such challenges are likely to impact caregiver health and well-being. This study explores the extent to which caregivers of children with both Neuro and behaviour problems differ in their physical and psychosocial outcomes from caregivers of children with either condition or neither condition. Method. The first wave of data collected in the National Longitudinal Survey of Children and Youth in Canada (1994) was used to identify four groups of caregivers of 4-to 11-year-old children: caregivers of children with a Neuro disorder and externalising behaviour problems (Both; n = 414), caregivers of children with a Neuro disorder only (Neuro Only; n = 750), caregivers of children with an externalising behaviour problem only (Ext Only; n = 1067), and caregivers of children with neither health condition (Neither; n = 7236). Results. Caregivers in the Both group were least likely to report excellent or very good health, and more frequently reported chronic conditions such as asthma, arthritis, back problems, migraine headaches, and limitations in activities as compared to the Neither group. This group also exhibited higher depression scores, experienced more problematic family functioning and reported lower social support than the Neither group. Scores for caregivers in the Ext Only and Neuro Only groups tended to lie between the Both and Neither group scores and often did not differ from one another. Conclusions. Caregivers of children with both neurovelopmental disorders and behaviour problems exhibited a greater number of health and psychosocial problems. While addressing childrens behaviour problems, health care professionals should also consider caregiver physical and psychosocial health, as this may also have an impact on childrens well-being.

Attention-Deficit Hyperactivity Disorder in Children and Youth: A Quantitative Systematic Review of the Efficacy of Different Management Strategies

Objective: To obtain estimates of the relative efficacy of 3 main treatment strategies for attention-deficit hyperactivity disorder (ADHD) in children and youth (age < 18 years). Methods: Design: quantitative systematic review of randomized trials. Subjects: 999 patients with ADHD from 26 randomized trials. Interventions: medications alone, behavioural interventions alone, and a combination of these 2 modalities. Main outcome measure: differences in scores between treatment groups on commonly used teacher- and parent-completed behaviour rating scales. Results: Medication-only therapy was efficacious in ADHD. Behavioural therapies used alone appeared not to be efficacious in ADHD. Combination therapy was more efficacious than placebo or no treatment for parent but not teacher ratings, not more efficacious than drug therapy alone, and more efficacious than behavioural treatments alone based on parent but not teacher ratings. Conclusion: Though stimulant medications were found to be an effective treatment strategy for ADHD in children and youth, it proved difficult to assess the relative benefits of behavioural interventions alone and combined medication and behavioural therapy because of the paucity of treatment studies other than medication-only treatment studies and heterogeneity of various kinds that exist in relation to ADHD studies and treatments.

Performance measurement and improvement frameworks in health, education and social services systems: a systematic review

PURPOSE To perform a systematic review, supplemented by a targeted grey literature scan, for performance measurement and improvement frameworks within and across the health, education and social service systems. The intended outcome was the creation of a foundation of evidence to inform the development of cross-sectoral quality improvement frameworks. DATA SOURCES MEDLINE, CINAHL, PsycINFO, ERIC, EMBASE, Social Services Abstracts, Social Work Abstracts and Education Index Full Text were searched up to April/May 2007. In addition, 26 governmental and 27 organizational websites were searched. STUDY SELECTION English language material with a publication date of 1986 or more recent that described a health, education or social services multidimensional framework for performance measurement and improvement. Data extraction The framework name; administrative sector; level of application; setting; population of interest; categories of quality described within the framework; country of application; and citations to other performance measurement and improvement frameworks were extracted from each article. RESULTS In total, 111 frameworks were identified. Most frameworks (n = 97) were developed in or for the health sector. A concept sorting exercise identified 16 quality concepts applicable across many settings, sectors and levels of application. CONCLUSION This systematic review of quality domains will be relevant and useful to those who are developing and using performance measurement and improvement frameworks for adult and child populations within or across the health, social service or education sectors.

Children's Persistence With Methylphenidate Therapy: A Population-Based Study

Objective: To examine persistence with methylphenidate (MPH) therapy among children and youth in the general population. Method: We conducted a retrospective analysis of longitudinally organized, individual-specific anonymous data from linked prescription and health databases covering the population of British Columbia for 1990 through 1996. No prescriptions being filled for 4 months indicated cessation of one bout of therapy. Results: Among 16 945 identified MPH patients aged 19 years or under, overall duration of therapy was 584 days, and the average number of prescriptions received was 6.6. One-third of patients received 2 or fewer prescriptions, while 18% followed a chronic, continuous course. Among patients receiving more than 2 prescriptions, 50% of discrete therapy bouts lasted 4 months or less, and one-third of cases had multiple bouts of therapy (range 2 to 6 bouts). Younger age (that is, children aged 0 to 8 years, vs those aged 10 to 19 years), male sex, and receipt of initial prescription from a psychiatrist were associated with greater persistence. Conclusions: Enormous variability in persistence with MPH therapy and often-occurring low rates of persistence raises questions about the diligence with which MPH patients are selected, prepared, and followed in the general population. Special attention to the needs of older children and to the needs of girls is required, and discontinuities during childrens therapy courses require explication.

Changes Over Time in the Health of Caregivers of Children With Health Problems: Growth-Curve Findings From a 10-Year Canadian Population-Based Study

OBJECTIVES We used Canadian population-based data to examine changes in the health of caregivers of children with complex health problems compared with caregivers of healthy children over a 10-year time period. METHODS The National Longitudinal Survey of Children and Youth collected data biennially from 9401 children and their caregivers in 6 waves from 1994-1995 to 2004-2005. We conducted growth-curve analyses of these data to model self-reported general health and depressive symptoms for 4 groups of caregivers: caregivers of healthy children, and caregivers of children with 1, 2, or at least 3 of 4 conceptually distinct indicators of child health problems. We modeled covariates for children (age, gender, only-child status) and caregivers (age, gender, education, income, marital status). RESULTS After we controlled for covariates, caregiver health outcomes worsened incrementally with increasing complexity of child health problems. Change in self-reported general health and depressive symptoms over the 10-year period was consistent across all groups of caregivers. CONCLUSIONS Poorer health among caregivers of children with health problems can persist for many years and is associated with complexity of child health problems. Attention to parental health should form a component of health care services for children with health problems.

Conceptualizing childhood health problems using survey data: a comparison of key indicators

BackgroundMany definitions are being used to conceptualize child health problems. With survey data, commonly used indicators for identifying children with health problems have included chronic condition checklists, measures of activity limitations, elevated service use, and health utility thresholds. This study compares these different indicators in terms of the prevalence rates elicited, and in terms of how the subgroups identified differ.MethodsSecondary data analyses used data from the National Longitudinal Survey of Children and Youth, which surveyed a nationally representative sample of Canadian children (n = 13,790). Descriptive analyses compared healthy children to those with health problems, as classified by any of the key indicators. Additional analyses examined differences between subgroups of children captured by a single indicator and those described as having health problems by multiple indicators.ResultsThis study demonstrates that children captured by any of the indicators had poorer health than healthy children, despite the fact that over half the sample (52.2%) was characterized as having a health problem by at least one indicator. Rates of child ill health differed by indicator; 5.6% had an activity limitation, 9.2% exhibited a severe health difficulty, 31.7% reported a chronic condition, and 36.6% had elevated service use. Further, the four key indicators captured different types of children. Indicator groupings differed on child and socio-demographic factors. Compared to children identified by more than one indicator, those identified only by the severe health difficulty indicator displayed more cognitive problems (p < 0.0001), those identified only by the chronic condition checklist had a greater likelihood of reporting allergies or asthma (p < 0.0001), and those identified as having elevated service use only were more affluent (p = 0.01) and showed better overall health (p < 0.0001). Children identified by only a single indicator were less likely to have serious health problems than those identified by two or more indicators.ConclusionWe provide information useful to researchers when selecting indicators from survey data to identify children with health problems. Researchers and policy makers need to be aware of the impact of such definitions on prevalence rates as well as on the composition of children classified as being in poor health.

Waiting for child developmental and rehabilitation services: an overview of issues and needs

Concern about the length of time that children, young people, and families may have to wait to access assessment, diagnostic, interventional, therapeutic, and supportive child developmental and rehabilitation (CDR) services is widespread, but adequate data collection and research on this issue remain limited. We review key concepts and issues relevant to waiting for CDR services from the published literature, a national workshop devoted to this topic, and international experience. We conclude that gaps in data, evidence, and consensus challenge our ability to address the issue of waiting for CDR services in a systematic way. A program of research coupled with actions based on consensus‐building is required. Research priorities include acquiring evidence of the appropriateness and effectiveness of different models of intervention and rehabilitation services, and documenting the experience and expectations of waiting families. Consensus‐building processes are critical to identify, categorize, and prioritize ‘sentinel’ components of CDR service pathways: (1) to reduce the inherent complexity of the field; (2) to create benchmarks for waiting for these respective services; and (3) to develop definitions for wait‐time subcomponents in CDR services. Collection of accurate and replicable data on wait times for CDR services can be used to document baseline realities, to monitor and improve system performance, and to conduct comparative and analytic research in the field of CDR services.

Responding to the needs of children with chronic health conditions in an era of health services reform

Between 15% and 20% of children and adolescents live with a chronic physical, developmental, behavioural or emotional condition.[1][1] Although diverse in terms of clinical characteristics, causes and treatments, chronic health conditions have a lot in common with regard to their impact on affected

Appropriateness of psychostimulant prescription to children: theoretical and empirical perspectives.

Objectives: 1) To consider study designs for evaluating how appropriately stimulant medications are prescribed to children. 2) To investigate appropriateness by seeking evidence of consensus around how stimulant management should be undertaken, collecting and reviewing evidence of actual physician practice in relation to use of stimulants, and evaluating the closeness of fit between recommended and actual practice. Method: Electronic databases and other published and unpublished material were searched for the decade 1987–1997 to identify 1) authoritative recommendations for medical management of attention-deficit hyperactivity disorder (ADHD) and 2) surveys of physician practice. Available information was analyzed qualitatively for commonalities and trends and for concordance between recommendations and practice. Results: Despite differences in emphasis between experts, common themes were identifiable regarding prerequisites and follow-up for use of stimulants. Overall, it was rare to find physician practice in accordance with expert recommendations more than 70% of the time, suggesting that management may be suboptimal in at least 30% of children treated with medication for ADHD. Across surveys, consistent differences appear in physician practice patterns related to practice type. Management by specialist consultants approximates standards recommended by experts, while management by primary care practitioners diverges from these standards. Conclusions: There are grounds for concern about the quality and appropriateness of medical management for children with ADHD. The methodology used in this study holds promise for wider application, with planning and refinement. There is a need to find ways to improve care for children with ADHD provided by primary care physicians.

Use of Medical Services by Methylphenidate-Treated Children in the General Population

OBJECTIVES To examine selected medical services for children treated for attention-deficit/hyperactivity disorder (ADHD) in a general population setting with universal health insurance. DESIGN Retrospective analysis of administrative prescription and health services databases spanning from 1990 to 1996. SETTING British Columbia, Canada. PATIENTS Children (<19 years of age) who had received the psychostimulant methylphenidate (MPH; Ritalin) on a chronic basis (chronic-MPH group), who had received MPH on any other basis (nonchronic-MPH group), and who were in a no-MPH comparison group. MAIN OUTCOME MEASURES The number of individuals who received any of the following services based on claims submitted by qualified practitioners: 1) emergency care, 2) critical care, 3) injury-related diagnostic and treatment services, 4) complementary and alternative medical (CAM) care, and 5) other diagnostic and treatment services (audiometry and allergy testing). RESULTS Prevalence of services users was higher among MPH-treated than nontreated children for all types of services (except critical care services in the chronic-MPH group) after adjusting for effects of age, sex, socioeconomic status, and geographic setting, with odds ratios ranging from 1.49 to 3.17. There were no differences between the 2 MPH-treated groups. CONCLUSIONS Children treated with MPH for ADHD or presumed ADHD are more frequent users of a wide range of medical services than are other children. Findings support and extend existing evidence of increased use of medical services by this population of children. Findings have implications for service planning, including injury prevention, with these children. High utilization of audiometric, allergy, and CAM services warrants further scrutiny.
