Review and further development of the Healthy Kids Check are crucial
Evidence-based systems of prevention and early intervention have long been a far-reaching goal for health planners and academics. This notion has assumed even greater importance in paediatrics because of the robust research now emerging about the early-life origins of a range of problematic health and psychosocial conditions later in the life course.1 Conditions as diverse as diabetes, cardiovascular disease, mental health problems and criminality have been linked to the environments experienced by unborn and young children. The idea of introducing a health check for children in order to detect emerging problems and risk factors, and offer treatment early in life, seems a natural and welcome policy response.
However, what seems such an intuitive concept faces a number of significant challenges in its implementation.2 These include the improbability of being able to check all children (with those most at risk being least likely to present for a check); the lack of reliable and valid measures in many domains (not fulfilling the scientific criteria for a screening test or program); the considerable developmental variability in young children (so that many problems are transient); and the difficulty in timely access to assessment and treatment services (cost, long waiting lists, and uneven coverage especially in rural areas).
In 2008, the Australian Government introduced the Healthy Kids Check (HKC). This was designed to be administered to all 4-year-olds before starting school, to promote “early detection of lifestyle risk factors, delayed development and illness, and … introduce guidance for healthy lifestyle and early intervention strategies” (http://www.health.gov.au/internet/main/publishing.nsf/Content/Health_Kids_Check_Factsheet). The HKC has been criticised for not being evidence-based3 and for its timing (many conditions and risk factors emerge earlier than 4 years of age). In addition, the focus is narrowly on health and largely excludes developmental and behavioural issues. On the other hand, a recent limited evaluation of the HKC in two general practices found that general practitioners “are identifying important child health concerns … using appropriate clinical judgement for the management of some conditions, and referring when concerned”.4
In 2012, the government established a multidisciplinary expert working group to provide advice about the introduction of an expanded Healthy Kids Check (EHKC), designed to be administered at 3 years of age and to replace the HKC. The working group systematically and carefully worked through the various issues — methods of early detection, selection of domains, professional training and expertise, referral and follow-up arrangements — and made a series of recommendations to government. The EHKC was designed to elicit and respond to any parent concerns about the child's health, development and behaviour, along with providing a physical assessment including measurement of height and growth and calculation of body mass index (http://www.health.gov.au/internet/main/publishing.nsf/Content/healthy-kidschk). The check itself was but one part of the process — also included were online training modules and a mapping template to facilitate referral for assessment and intervention. Piloting of the EHKC was undertaken in several states by the Australian Medicare Local Alliance, which submitted an evaluation report to government in November 2013.
The process of designing the EHKC highlighted some of the challenges in developing and introducing an approach to prevention and early intervention in child health. There was uninformed criticism — in the media as well as in peer-reviewed journals5,6 — that this was a mental health check and that the EHKC was designed to screen for mental health problems. This perception may have arisen from the inclusion of questions designed to elicit parent concerns about the child's behaviour, and because funding for the development of the EHKC was provided by the mental health branch of the Department of Health. Rather than being a screening test, the EHKC was conceptualised as providing an opportunity for parents to raise any concerns with their child's GP. These would be addressed using the GP's clinical judgement — reassurance, providing appropriate advice, or referral for further assessment and management — facilitated by appropriate training and a mapping template to document local community supports and referral agencies. The government is apparently considering the evaluation report, generally very positive, but no decision has been made about the introduction of the EHKC. Meanwhile, the HKC continues as a Medicare-funded check for 4-year-olds.
While the idea of prevention and intervention early in life is compelling and the research underpinning it largely uncontested, it is a hard sell to government and there are many challenges in its implementation. Early detection of emerging problems is problematic. Many issues in young children are transient, and we do not have reliable and valid methods to know which children we should be concerned about. The evidence suggests that systematically eliciting and responding to parent concerns is the best method for early detection (Murdoch Childrens Research Institute, Centre for Community Child Health; submission to the Victorian Government, March 2009). Making the check part of Medicare removes a potential financial barrier for uptake but still does not ensure that all children, especially those at risk, are seen in a timely fashion.
The primary health care system must be at the heart of efforts to refocus the health system towards prevention and early intervention, so GP involvement in undertaking the child health checks is important. It is to be hoped that the government persists with the ongoing review and informed evolution of the child health check, and that the challenges and concerns that are an inevitable accompaniment to introducing any population health measure are addressed appropriately.
