Abstract

There are few more heated issues in Australian mental health than determining the value of the Better Access to Psychiatrists, Psychologists and General Practitioners through the Medicare Benefits Schedule (Better Access) initiative. In our view, the need for genuine, well-designed and ongoing evaluation of its impacts has never been seriously addressed [1]. Sadly, the publication of aspects of the extremely limited government-purchased ‘patient outcomes’ evaluation [2] adds very little to our knowledge base.
An historical and primary care policy perspective
Enhancing affordable and equitable access to relevant psychological therapies has long been at the heart of reforming primary care-based mental health services in Australia [3–5]. In the late 1990s, the SPHERE Project (based on an evaluation of 46 515 ambulatory patients attending 386 general practitioners) demonstrated the extent to which those attending general practice in Australia with significant mental disorders were unable to access skilled psychological interventions [6–8]. Over the same period there was community and professional concern at the rapid expansion in pharmaceutical treatments for anxiety and depression in primary care settings [9].
In July 2001, after an intensive campaign led by beyondblue: the national depression initiative, acting in partnership with mental health consumers and the relevant medical and psychological professional groups [10,11], the Howard Government introduced the landmark Better Outcomes in Mental Health Care (BOiMHC) programme [12]. For the first-time, specialized psychological services were supported financially through our standard general practice systems [13,14]. This was a major breakthrough for mental health and a fundamental re-orientation of Medicare Australia towards direct support for skilled professionals, including psychologists and other health workers, to deliver evidence-based interventions.
Though funding was limited (AU$$120 million over four years), the design and payment elements rewarded coordinated and collaborative care by general practitioners and other skilled professionals. The provision of ongoing collaborative care, and not simply cross-referrals between health professionals, has been highlighted by the Institute of Medicine of the National Academies (IOM) as one of the most important drivers of enhanced quality in mental health practice [15]. Distributing payments through Divisions of General Practice, rather than paying directly to largely urban-based providers, also helped to overcome both geographical and socio-economic barriers to care.
In April 2006, in response to community pressure to expand access, the Howard Government committed $$538 million over five years and replaced the BOiMHC with the new Better Access initiative [16]. This change in focus was largely in response to many of the professional groups who lobbied hard for a return to traditional fee-for-service payments and extension of the scheme to non-medical providers with limited clinical training or experience. Better Access was the largest single part of the Australian Government's contribution to the 2006–2011 Council of Australian Governments' (COAG) National Action Plan on Mental Health, and recognised the value the community placed on moving beyond medical and more institutionally based forms of mental health care [3,17].
As a consequence of those political decisions, Better Access moved the goalposts away from provision of quality services (with its linked focus on enhancing outcomes) to promoting entry to any service (with the focus on access). In opposition, the Australian Labor Party countered by promising a return to a more equitable balance of services, driven by population need rather than professional convenience or incomes. Subsequently, the Rudd Government released the first data on the impacts of Better Access, and analyses by the Mental Health Council of Australia (MHCA) demonstrated the predicted inequities (which are intrinsic to the Medicare model) related to socio-economic status and geography [18,19]. Repeated examination of subsequent data by the MHCA, and the recent Summative Evaluation [20], have confirmed those same trends (Table 1).
Utilisation of Better Access MBS item numbers
The 2011 budget reforms
Modelling of the further growth of Better Access for the 2011 Budget process predicted that the initiative was expected to cost at least AU$$4 billion over the next five years [24]. Consequently, the Gillard Government has now begun to revise the initiative. This has occurred largely in the policy and fiscal context of developing a 10-year road map to guide the next round of broader mental health services reform. The 2011 Budget introduced limited reforms, focused mainly on reducing remuneration for the planning role of general practitioners but also introducing minor reductions in the number of psychological services by non-medical practitioners [25].
Neil Cole, Consumer Advocate and Member of the National Advisory Council on Mental Health (NACMH; 2008–2011):
Better Access is simply middle class welfare masquerading as a mental health scheme. The cost is so high that other more important concerns are not being addressed. If one third of the money spent on Better Access went to much needed public housing, most of the homelessness experienced by people with mental illness would be solved. [Cole N: personal communication]
The challenge now for the Gillard Government is to achieve an appropriate balance between population-based initiatives, health services reform (particularly integration of primary care and more specialised services), increased support for housing, employment, education and other social services for those with mental illness and systematic evaluation. To achieve that balance, it will rely increasingly on evidence from the field to guide future choices.
Questions that still require answers
…it was beyond the scope of the evaluation to consider whether Better Access is an appropriate policy initiative. [20, p.45]
As we have detailed elsewhere [1], the key questions surrounding Better Access relate specifically to the extent to which it represents a major improvement over prior systems (e.g. pre-2001 general practitioner-delivered care or BOiMHC 2001–2006). The somewhat newer question is whether it is superior to alternative systems, particularly those that can be delivered by Internet-based technologies [26,27]. Further, even if Better Access does indeed have better service delivery characteristics than either previous or alternative models, are those benefits being achieved in a cost-effective manner, and what are the work-force implications of rapidly expanding this mode of service delivery? In agreement with Jorm [28], the next level of questions relate not just to health service effectiveness but wider population-health impacts (e.g. reduction in suicide, self-harm, income support, non-participation in education and employment).
However, Jorm [28] distorts the public debate about the adequacy of the evaluation by framing the question as ‘do the evaluation data support the critics?’ (p.1). By contrast with Allen & Jackson [29], he fails to ask whether we actually have any substantive data on which to continue to promote such an expensive and intrinsically-flawed service delivery model? That is the fundamental health services question that has preoccupied the major critics – who include a broad group of consumers, medical and psychological health professionals and health commentators. For Jorm's [28] more limited set of questions, in our view, either the available evidence demonstrates clearly the inadequacies of Better Access or the questions simply cannot be answered by the sub-standard evaluation or any other available data sources (see Table 2).
The Better Access evaluation – Jorm's [28] questions that still deserve answers
The inadequate evaluation
John Mendoza, former Chair of the NACMH (2008–2010):
In my role as Chair of the NACMH, I clearly indicated to the Minister that I did not believe the evaluation, routine data collection and reporting systems would sufficiently contribute to the evidence-base, or to enable the Government to be confident that each of the Better Access items are sufficiently effective when compared to other treatment and therapy options. It will only establish that Better Access assisted those who volunteered through their provider to participate in the evaluation – a clearly biased patient and provider sample. [Mendoza J: personal communication]
By contrast with Mendoza's warning, Jorm [28] in his remarkably sanguine review of the evaluation, suggests that ‘we have to make the most of what evidence is available, however imperfect’ (p.2). The triad of defences that ‘The new services have proved very popular’ [28, p.2], the limited scope of the evaluation, and that some population-based data are not in disagreement with the evaluation, are the style of responses we normally expect from government rather than the academic sector.
In regard to the scope of the evaluation, of the 2429 practitioners approached, a mere 5% (or 129 practitioners) self-selected just 883 patients (an average of only seven patients per practitioner) from an initiative that provided services to 1 130 384 individuals in 2009 alone and a total of 2 016 495 individuals over three years. In terms of other clinical outcomes data, closer inspection showed it to be extremely limited [40,41, Hitch D: personal communication]. Furthermore, all patient-level clinical data were entered by providers themselves, including prior use of mental health care [2].
The Summative Evaluation of Better Access [20], and the Jorm editorial [28], place considerable weight on implied support from a separate analysis that utilized data from the 2007 National Survey of Mental Health and Wellbeing [42]. Importantly, that survey relied on what the authors themselves describe as ‘unverified, retrospective self-report’ [42, p.106]. Further, the authors conducted very detailed sub-analyses (for demographic, prevalence and type of disorder and patterns of health service use) on only 175 individuals. They concluded ‘the relatively small numbers available for some comparisons…may have limited the power…to detect some differences in sociodemographic profile and treatments received’ [42, p.106]. Of interest, the patients reported receiving psycho-education and non-specific counselling as distinct from the (provider-reported) provision of cognitive behavioural therapy (CBT) emphasized in the report by Pirkis et al. [2].
Finally, Pirkis et al. [2] acknowledged that they did not address the possibility of inequity of service access. However, in terms of the number of Medicare Benefits Schedule (MBS)-subsidised Better Access services received in 2009 [20], there is clear socio-economic inequity. The highest quintile/least disadvantaged part of the treated group received 1 385 364 services compared with 547 063 services in the lowest quintile/most disadvantaged group. This socio-economic inequity simply continues the pattern previously reported for access to antidepressant therapies [43]. More recent analyses of the National Mental Health and Wellbeing Survey, suggest that socio-economic discrepancies may actually have increased between 1997 and 2007 [Meadows G: personal communication].
Evaluation of new service systems and Internet-based models
Helen Christensen, Professor and Director, of the Centre for Mental Health Research, College of Medicine, Biology and Environment, the Australian National University:
Internet applications have a place in the treatment of people with anxiety and depression. They can be tools to promote self-help, or to guide self-help, and they offer effective treatment to people in the community without access to help, with a preference for these forms of treatment and who cannot travel for psychological treatment. Moreover, they release clinical psychologists and others from the behavioural teaching required to implement CBT, to focus more on individuals with complex, severe, and potentially life threatening conditions, who need sustained and challenging interventions.' [Christensen H: personal communication]
One of the major, perhaps unintended, consequences of the focus on enhancing the quality of services for those already in care, has been much less emphasis on promoting early intervention (particularly in those aged 16 to 25 years) or developing alternative delivery models. The early successes of alternative primary care pathways for young people (largely delivered through the headspace, Australia's National Youth Mental Health Foundation network of services [44,45]) and the increasing use of the Internet to deliver structured psychological treatments [46–48] have now created other major competitors to Better Access.
Both these new pathways engage key population groups that do not use traditional primary care and appear to deliver services in a much more cost-effective manner. Specifically, the relative cost advantages of e-health services can hardly be ignored. When comparing face-to-face group CBT with Internet CBT for social phobia, Andrews et al. [39] found both to be equally effective, but reported that Internet therapy required less clinician time and was 13 times more cost-effective. Contrary to clinician beliefs, Andrews et al. [39] also reports that over 95% of people attending the St Vincent's Public Hospital (Sydney) Anxiety and Depression Clinic opt for Internet CBT over face-to-face CBT. He proposes that no travel costs, the ability to redo lessons and the convenience of doing the lessons at any time were the principal reasons that underpinned this strong patient preference.
Other independent studies have addressed these issues. For example, Mihalopoulos and colleagues [49] assessed the incremental cost-effectiveness of panic disorder supplemented by a psychologist or general practitioner compared to usual care, finding savings of AU$$4300 per disability-adjusted life year (DALY). More recently, Warmerdam et al. [50] reported positive results for the relative cost utility and cost effectiveness of Internet CBT for depression. Spek [51] compared Internet (€323 per person) with group treatment (€1830), with a saving of €151.50 for significant change associated with Internet compared to group treatment. The clinical effects were the same for the Internet and group interventions.
MoodGYM, a preventative e-health application developed by Christensen and colleagues [38], delivers a minimum effective dose (two or more sessions) to approximately 11 048 users annually, at a cost of $$5 per person or $$72 for each DALY averted. In the broader set of trials reviewed by her Australian National University group, Internet-based interventions are associated with effect sizes of 1.0–1.2 in clinical samples, and that these effects are similar whether the individual is ‘tracked’ by a counsellor or received automated email messages. In our own work with general practice in Australia, we have demonstrated the feasibility and efficacy of usual general practitioner care supplemented by Internet-based CBT, with no need to refer to another provider [52].
As we have just seen with the 2011 Budget changes to Better Access, the cost characteristics of face-to-face services inevitably mean that limits need to be introduced quickly to any programme that responds to community need. To May 2011, over six million ‘CBT-like’ services had been delivered by registered psychologists at a cost of more than $$500 million (to government), or approximately $$82 per service or $$410 per treatment delivered (average of five sessions, see Table 1). There is an additional $$150 per person on average of direct cost to the patient. The relative value of MoodGYM in full operation (at $$5 per person treated to government and free to the patient) is clear. Additionally, it is not limited by workforce capacity constraints, training requirements, work practices or geographical distribution of providers.
Gavin Andrews, Professor of Psychiatry at the University of New South Wales and St Vincent's Hospital, Sydney Australia:
Only the medical colleges and the other professional associations, and the Federal Department of Health and Ageing, still think that patients want to see the doctor or the psychologist. Actually they just want to get better as quickly and cheaply as possible. [Andrews G: personal communication]
Are more people in need receiving care?
One of the more important propositions arising from work derived from the Summative Evaluation [20] is that access to care for those with a mental disorder has increased from 37.4% to 46.1% (during the period 2006–2010) as a consequence of the introduction of Better Access. The data, however, do indicate that in the 12-month period to 2009–2010 there was just a 1.1% increase despite this being the highest year of utilisation of Better Access [20].
The data analyses also assume that there has been no change in the rate of overlap in use of Commonwealth and state-funded services since the introduction of the initiative. One of these assumptions was no change in the overlap of patient populations between state/ territory and Commonwealth mental health services. However, if one assumes a more realistic increase in overlap between these patient populations (e.g. range: 1% to 3%, average: 2%), the estimate of the increase in service use may be as modest as 37.4% to 44.1%.
Is this the best way to purchase care?
On the most optimistic of interpretations, for a price tag of $$1.5 billion, the Government purchased a maldistributed (by socio-economic, demographic and geographical parameters) 8.7% (range 4.2% to 13.4%) increase in active treatment of primary care-based mental disorders. That is, most people with disorders are still not receiving care. It is also important to note that neither BOiMHC or Better Access were designed to meet the genuine needs of those with more severe, complex or ongoing disorders. While the 2011 Budget has for the first time placed much greater emphasis on developing new care systems for those with severe or persisting illness [30], those who would benefit from prolonged psychological therapy (e.g. borderline personality disorders, eating disorders, chronic depression, complex medical and psychological problems, severe anxiety with substance misuse) are still likely to receive no or very inadequate care [53]. The reality is that no level of government has ever accepted responsibility for provision of effective care packages for these groups.
As we move into the next 10-year plan, the lessons from the last decade of primary care-based reform are clear enough: those who genuinely wish to promote better access to short or longer-term psychological care (particularly that which promotes earlier intervention, more collaborative care, greater equity, minimisation of financial burden, support for more skilled practitioners who can deal with greater complexity, greater flexibility in delivery modes and greater cost-effectiveness), will be in search of better policy options than the current Better Access initiative.
John Mendoza, former Chair of the NACMH (2008–2010):
When chairing the NACMH, there was a consensus (but not unanimous) view in the wider mental health sector that Better Access was largely a provider or supply-driven system. While there was a view that the huge demand and uptake of the services by patients was evidence that Better Access was a successful initiative, it was not the broader view! The majority view was that the initiative in its current design was unsustainable and importantly, not the best buy when compared with collaborative care models. [Mendoza J: personal communication]
