Abstract
Background
While integrated primary healthcare for the management of depression has been well researched, appropriate models of primary care for people with severe and persistent psychotic disorders are poorly understood. In 2010 the NSW (Australia) Health Department commissioned a review of the evidence on "shared care" models of ambulatory mental health services. This focussed on critical factors in the implementation of these models in clinical practice, with a view to providing policy direction. The review excluded evidence about dementia, substance use and personality disorders.
Methods
A rapid review involving a search for systematic reviews on The Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effects (DARE). This was followed by a search for papers published since these systematic reviews on Medline and supplemented by limited iterative searching from reference lists.
Results
Shared care trials report improved mental and physical health outcomes in some clinical settings with improved social function, self management skills, service acceptability and reduced hospitalisation. Other benefits include improved access to specialist care, better engagement with and acceptability of mental health services. Limited economic evaluation shows significant set up costs, reduced patient costs and service savings often realised by other providers. Nevertheless these findings are not evident across all clinical groups. Gains require substantial cross-organisational commitment, carefully designed and consistently delivered interventions, with attention to staff selection, training and supervision. Effective models incorporated linkages across various service levels, clinical monitoring within agreed treatment protocols, improved continuity and comprehensiveness of services.
Conclusions
"Shared Care" models of mental health service delivery require attention to multiple levels (from organisational to individual clinicians), and complex service re-design. Re-evaluation of the roles of specialist mental health staff is a critical requirement. As expected, no one model of "shared" care fits diverse clinical groups. On the basis of the available evidence, we recommended a local trial that examined the process of implementation of core principles of shared care within primary care and specialist mental health clinical services.

In 2008 the New South Wales (Australia) Government's Mental Health Sentinel Events Committee published its fourth report which concluded: "a definitive set of best practice standards to guide the development and implementation of shared care for mental health consumers is lacking" [1]. This Committee found cases of homicide and suicide where patients had been "under some form of shared care arrangement" but with no effective system to ensure oversight and take action where necessary. This report was referred to the New South Wales Government Department of Health and via brokerage with The Sax Institute, Sydney NSW, an expert evidence check or rapid review was commissioned.
The authors were contracted to conduct the review. This included negotiation of the research questions, presentation of preliminary scoping, draft and revised final reports. Questions and clarification were addressed via consultation involving all parties throughout the process. This form of knowledge exchange has been described as "the problem solving, policy driven model" but it might equally operate through a process of enlightenment by which evidence and ideas permeate the policy making system [2]. Rapid reviews are a new and contentious approach to knowledge transfer and exchange between researchers and policy makers. They are typically conducted in months rather than years and the focus is determined by policy-makers rather than researchers. The strength of a rapid review lies in its timeliness and responsiveness to the needs of policy makers and practitioners, but its limitations include the reliability and generalisability of the findings [3]. It has been argued that rapid reviews provide local guidance and are useful resources in the later development of a traditional systematic review [4]. To provide timely and responsive advice the search process is accelerated and the findings of existing systematic reviews emphasised, but some harder to find material in the grey literature may be missed. This may introduce biases and it has been suggested that rapid reviews should carry a warning to the effect that guidance may be revised if and when a relevant systematic review is published [5].
There is increasing recognition that improving the detection, treatment and outcomes for mental health problems requires service models that integrate mental health care within primary health care practice [6]. While much of the research to date has focussed on primary care management of depression [7], the complex needs of people with more severe and persistent mental illness has received less attention. Despite the achievements of a well-established tradition of general hospital based consultation-liaison psychiatry (comprising consultation, specialist support, collaboration and joint care) there is only limited evidence for the translation of these principles to community ambulatory and primary care [7]. Although sometimes referred to as "consultation-liaison services in primary care" [8] these models of "shared care" are often poorly defined, ranging from the simple transfer of care from one provider to another, to the involvement of one or more services in patient care, through to formalised cross-service arrangements [9].
The rapid review was undertaken to investigate the evidence underpinning "shared care" in ambulatory mental health care. The focus related mainly to adults with severe and persistent mental disorders. Evidence regarding treatment models for a broader range of conditions (e.g. dementia, substance use disorders, or personality disorder) was outside the scope of this review.
The review addressed the following questions:
-
1.
Does "Shared Care" improve clinical outcomes for people with mental illness?
-
2.
If so, what are the proposed ingredients of an effective "Shared Care" program?
The latter required hypothesising a proposed set of such ingredients based on a synthesis of the literature.
Methods
The research team comprised a psychiatrist with research, clinical and teaching responsibilities, a nursing academic with research and clinical experience in mental health services, a health systems researcher specialising in mental health and primary health care and an information scientist with mental health nursing experience. The group had recently completed a 12 month narrative review of effective service linkages in primary mental health care [10] were familiar with the literature and had established working arrangements. They also had many years of experience with the NSW health care system and brought a strong understanding of service and political context.
Shared care covers a broad spectrum of collaborative treatment arrangements and there is no standard definition in the literature [11, 12]. For the purposes of this rapid review, we developed the following definition based on the published literature:
A structured system for achieving integration of care across multiple autonomous providers and services[13]with both primary and secondary care practitioners contributing to elements of a patient's overall package of care[9]. Shared care involves some agreement about the shared activities and levels of responsibility for each provider and appropriate communication processes to support this integration. A shared care arrangement may involve any combination of government, non-government or private sector providers.
As a rapid review, the initial step was to identify systematic reviews and examine their relevance. This was followed by a search for papers published subsequent to these systematic reviews as well as iterative searching from reference lists for any outstanding published works. The search for systematic reviews was conducted in the Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effects (DARE) (2004-2010). A comprehensive search strategy was developed and applied to Medline (Additional file 1). One person (SP) assessed each title and abstract against the inclusion and exclusion criteria (Additional file 2) and consulted with a second author where there was any uncertainty. Focussed data extraction was undertaken and extracted material discussed and explored during project meetings.
We found six systematic reviews of shared or collaborative care that included people with a mental disorder [10, 11, 14–17], several covered depression in some depth [10, 15–19]. We then reviewed 271 citations from the black search of which 23 dealt with mental health conditions other than adult depression. We included 12 studies of severe or persistent mental illness (21 citations). Two addressed bi-polar disorder [20, 21], nine severe or chronic mental illness [22–29], and one first episode psychosis [30].
Results
Does shared care work?
The benefits of shared care models are summarised in Table 1. The highest quality evidence (level 4) [31] comes from US and UK studies of the treatment of mental disorders in primary care, such as depression and anxiety (often in the context of coexisting physical conditions such as diabetes, cancer or cardiovascular disease). These trials mainly recruited those aged 60 or over [32, 33].
Depression and other common mental disorders
Smith [11] undertook a detailed meta-analysis examining 20 studies of shared care for chronic disease management, six of which examined shared care for depressive disorders and 3 persistent mental illness, the remainder investigating a range of shared care interventions for chronic physical conditions. The most consistent finding was in prescribing and drug treatment adherence in favour of shared care interventions. The six studies of shared care for depression alone reported evidence of benefits in rates of recovery or remission [33–38]. Nevertheless, Smith drew the sobering conclusion that overall "consistent evidence for the effectiveness of shared care is lacking for most of the outcomes studied". The authors go on to conclude that effectiveness may be greater for clinical subgroups, highlighting findings among patients with depressive disorders particularly.
While most studies to date have focussed on depression either alone or in combination with chronic physical illness, a recent RCT investigated a flexible treatment delivery model for collaborative primary care management of people with multiple anxiety disorders (CALM) [39]. This study demonstrated significant improvements in anxiety and depressive symptoms, functional disability and in measures of quality care.
A meta-analysis of interventions targeting improved communication strategies between primary care providers and specialists (representing a model of "shared care" for the purposes of our review) by Foy [14] found moderate overall effect sizes for a range of chronic conditions, including mental disorders (18/38 studies) with similar effect sizes across conditions. This review also found that effect size increased when analysis was restricted to studies of depression. This supports the results of meta-analyses of depression trials [15, 17] that have reported positive clinical outcomes, increased use and effective treatment with antidepressants and sustainable benefits for up to 5 years.
Two large US trials on collaborative care for depression (IMPACT and PRISM-E) also reported results for subgroups from ethnic minorities [40, 41] with both reporting similar results to the general patient population studied.
Severe and persistent mental disorders
There were fewer published papers about the benefits of "shared care" for severe and persistent mental disorders (e.g. schizophrenia) and very little work about service links outside the health sector with welfare, housing, education, or employment.
Despite a high need for health and social services for people with such persistent psychotic disorders, Fuller [10] found only 16 of 119 reviewed studies examined such services. Of the RCTs, three reported some clinical benefit including improved mental and physical function [42] improved physical function [23] and reduced relapse rate [22].RCTs by Lester and Warner [26, 43] of patient-held records found no clinical or service use benefits, while a cohort study by McDonough [44] reported no clinical or service use benefit from a GP-Community Health Team shared care register. However, an RCT by van Orden [29] found no clinical benefit from an on-site mental health worker in primary care, but reported decreased waiting time to see a mental health professional and decreased mean number of referrals for specialised mental health appointments. Other studies of co-located services have reported improved communication among providers, and increased referral to mental health services [45, 46].
Studies of Assertive Community Treatment (ACT) [20, 47, 48], found no significant clinical outcomes but improved social function, quality of life and satisfaction, decreased hospitalisation and improved engagement with services. A trial by Druss [23] of veterans with severe mental illness also reported service improvements. Those receiving integrated medical and mental health care were compared with those receiving usual care in a general medicine clinic. After one year, veterans assigned to the integrated care clinic reported significantly improved access and quality of care (e.g. fewer problems in access to mental health services, greater attention to consumer preferences, courtesy, and coordination). The largest effect was in continuity of care.
Two studies of supported housing and mental health follow up using ACT principles for people with persistent and severe mental illness reported improved quality of life, better physical health, higher satisfaction and improvements in housing stability and perhaps because of this, improved treatment engagement [24, 27]
We found no evidence of programs reporting adverse clinical outcomes.
What are the necessary components of effective shared care services?
On the basis of the existing studies, a major focus of this review was the inductive process to propose or hypothesise a set of "core ingredients" that comprise effective shared care, providing a base to inform future service development projects.
It was evident that models of shared care varied in complexity reflecting the target population, the structure and organisation of the health services in which they were located, and other local factors [49]. Shared care covered a broad spectrum of collaborative treatment arrangements, where provider involvement fluctuated depending on consumer need and so there was no single model to fit every community or situation [12]. Regrettably, while studies have demonstrated some benefits from these multi-component interventions across patient outcomes, service use and some costs, there is less evidence from such studies regarding the process of service change required to achieve these outcomes.
In general, effective collaborations were found to use multi-component strategies that reflected the following: i) the chronic and complex nature of many mental health problems, ii) the need to improve access to and engagement in treatments (e.g. through co-location of general and mental health services to lessen stigma), iii) the need to improve treatment adherence and continuation through care coordination, facilitation and monitoring [50] and iv) strategies that applied a clear set of core ingredients to promote service collaboration but with capacity for flexibility to local needs and context [51]. Without differentiating between the type of mental illness, Fuller [10] identified that most trials with positive clinical, service use or economic outcomes employed multiple linkage strategies that include some "direct collaborative activity", "guideline initiated care" and "a communication system". For the purpose of this review we have tabulated five of the major international studies on shared care for depression and anxiety (Table 2) and twelve for severe and persistent mental illness (Table 3 and Table 4) in an attempt to examine the common components of such interventions across these studies. Common components across both the depression/anxiety and severe and persistent mental illness studies are case management and care coordination roles (chiefly with mental health expertise), clinical supervision, follow up and use of standard outcome measures. Treatment algorithms were most evident in the depression/anxiety studies but not in the studies of persistent mental illness. The use of specific strategies targeting enhanced communication between providers is particularly evident in the persistent mental illness studies.
Based on a synthesis of these findings, the following discussion proposes specific elements of effective shared care services while acknowledging this complexity and the overlap of these elements.
Clarity of Intervention
Studies demonstrating improved outcomes for depression and anxiety using "shared care" in primary care have usually been well articulated clinical treatment models within an established theoretical framework such as Problem-Solving Therapy [33].The evidence suggests that successful shared care requires a clear clinical focus tailored to the needs of particular conditions or patient subpopulations, specific selection of patients, coherent treatment models and agreed strategies to monitor treatment progress. These include, step-wise escalation and de-escalation of treatment intensity (type, frequency and duration) or urgency of response as needed and with mechanisms to ensure the maintenance of the necessary skills to deliver interventions [50, 52, 53] such as expert clinician supervision. Some studies also utilised patient education and self-management resources within stepped care intervention models. Some studies explicitly included patient treatment preferences [39]. This is an important feature since intervention studies need effective treatment options that are acceptable to consumers for broader implementation [54].
In contrast, studies of persistent and severe mental disorders such as schizophrenia have often entailed service brokerage and linkage interventions with less emphasis on particular therapeutic strategies or clearly articulated service models. Rather, they focus on the process and organisational aspects of care and ensuring engagement and communication across service sectors, such as housing, employment, hospital and community-based care [20]. Studies in these populations also suggest that the benefits of specialist and primary care jointly working together are most evident when there is face to face contact with experienced mental health workers for case discussion than just case register or proactive recall strategies [44, 51].
Staff attributes and skill
Fuller [18] found that the attributes and skills of staff were important and linkages were enhanced when key staff had experience in both mental health and primary care [55–57], and when clinical staff had a flexible work style that helped them to fit into a team [55, 58, 59].The majority of studies targeting patients with persistent and severe mental illness, incorporated roles for identified mental health professionals, working within primary care to implement the shared care intervention with a range of tasks including care coordination, case review and liaison activities with primary care. Referred to in some instances as "link workers" [60], such roles were aimed to build "linkages" between primary care and specialist mental health services. Byng [60] found that the level of experience and flexibility of such specialist mental health link workers was important, particularly to achieve the benefits of their participation in face to face consultation for patients in "crisis". When staff doubted the value of a collaborative strategy, such as a formalised referral method, then this has resulted in low uptake of the strategy [63, 64].
While some studies suggest outcomes are better when care coordination is provided by mental health trained practitioners [17] others find that these skills can be developed by non-specialist health care providers if supported by training, regular case supervision and mentorship. These elements allow for direct patient consultation by specialists if needed [61, 62] or for face to face consultation between primary care and specialist clinicians when needed [21].
While the need to increase the supply of mental health professionals is widely accepted, in some instances evidence suggests that efficient and effective use of specialists can support integrated delivery of care within primary health care sector. Improving the confidence, capacity and engagement of primary care clinicians in mental health care does however require attention to their support, training and supervision and to the attitudinal barriers to mental health service provision [63]. Jointly managed and funded collaborative care arrangements may help to address these barriers. This can be achieved while retaining the capacity to respond to the needs of the most complex patient [6].
Purposively designed care delivery system
Butler [64] noted that most trials of collaborative care built on the Chronic Care Model [65] include self-management support, a purposively designed care delivery system, decision support tools and a clinical information system.It is interesting to note the findings from a "Realistic Evaluation" of the UK-based program established by [51], which reveals the importance of contextual factors in tailoring the intervention to local needs, based on a mixture of fixed and flexible components that enabled a shared care agreement that reflected the local context. It is also interesting to note that electronic data register systems were perceived as less important in achieving the goals of this shared care intervention. Findings from this study suggest that so-called "catalyzing" functions (i.e. the integration of a mental health link worker into the primary care team, and facilitated planning) and "doing" (e.g. face to face discussion of patients and provision of advice when required,) were more effective than interventions based on improving information technology [60].
Clarity of roles
Role clarity is an important component of collaborative development and sustainability [23, 66]. Yaffe [67] found that in 40% of cases primary care and mental health clinicians disagreed about the responsibility for and purpose of a referral (i.e. whether to assess or to treat). In the IMPACT study on depression, team and worker role clarification was used to identify safe practice boundaries [56].
Leadership and governance
Butler noted that overcoming local organisational and cultural barriers requires strong leadership to champion change [5].S hared governance arrangements between primary care and specialist services were found to support faithful application of evidence-based shared care models [60, 68, 69]. Such clinical governance was needed to promote (1) clear, agreed lines of clinical accountability, (2) clinically appropriate interventions linked with clear methods to ensure appropriate clinical supervision of staff [17, 70], and (3) appropriate evaluation of the "shared care" model [17, 39, 50, 52]. Formal service agreements were found to build organisational support for "shared care". In several trials this was an important means to establish a mandate, change leadership and provide resources for integration [55, 57, 71–73].
Funding
The ACCESS trial found that mental health and human services that received direct funding and technical support achieved better integration [74], while Butler [64] described financial and organisational barriers to collaborative service arrangements including: the lack of reimbursement for activities such as care planning with other providers, and the restrictive rules imposed when combining funds from different sources; difficulties employing staff with the skills for new roles crossing mental health and primary care; and the costs of collaboration.
In most studies the research provided additional staffing and organisational infrastructure that was "grafted" onto existing services, with some service re-orientation. However, some small effectiveness trials did provide a more robust "bridge" to routine practice by utilising existing staff and resources [22, 53] such as identification of mental health link workers, with researchers providing facilitation, tools and limited funding to support project implementation [21].
Physical infrastructure
Physical infrastructure was also important. The provision of co-located accommodation was an enabler of collaboration, when mental health care managers were located in the primary care clinic enabling optimum team visibility and interaction [56], but a barrier when clinic accommodation was inadequate [75]. Interestingly low uptake of quality improvement (QI) programs designed to increase collaboration between primary care and other specialist mental health and community mental health services has been attributed to a lack of face to face contact between primary care and mental health specialists [65].
Feedback about outcomes
In the IMPACT study [56, 71]"the most important factor, cited in four of the five sites, was the ability to document positive client outcomes from the research study". Mechanisms to feedback evidence of outcomes to team staff seems to have been a key contributor to developing and sustaining service collaboration in this study, however the value of this process was not reported more widely in the other reviewed studies.
Discussion
"Shared Care" between specialist and generalist services has been a major focus of mental health service reforms. The purpose of this rapid review was to examine published evidence about models of shared care in mental health with specific attention to the core ingredients and processes necessary to support effective shared care models. The available evidence suggests that models of "shared care" between primary health services and specialist mental health service can lead to improved clinical outcomes in some clinical groups, such as depression and anxiety disorders. There is a small amount of evidence that shared care can provide better outcomes for people with psychoses and related disorders, such as reduced relapse rates. The complexity of the systems of care necessary for people with these disorders, may explain the limited evidence for shared care in this setting.
The literature to date has used inconsistent definition of shared care; hence it is not surprising that it is difficult to distil core elements of effective care from existing studies. Furthermore the majority of the evidence is drawn from studies addressing depression and anxiety. There is less evidence regarding shared care in severe and persistent mental disorders and we cannot readily assume that models developed for the former will work with the latter.
On the basis of this rapid review we deduced a number of core ingredients of effective shared care models. These comprise provision of collaborative care in a coherent, evidence-based clinical management framework with:
-
i)
A systematic approach to the engagement of primary and specialist services towards the common goal of improved mental health care
-
ii)
A coherent treatment model relating to the target condition/s or patient population,
-
iii)
An agreed clinical pathway and monitoring of patient outcomes with the provision of case review by specialist personnel when needed
-
iv)
Attention to staffing requirements and the provision of clinical supervision to support skill development and maintenance of treatment model [50, 53].
-
v)
A well-established clinical governance framework.
In studies of shared care for people with persistent and severe mental disorders, a common element was the provision a care coordinator acting as a link between primary care and specialist mental health services.
A broader issue is the challenge of the translation of evidence into clinical practice. The gap between evidence-based care and clinical practice is widely acknowledged. While many studies demonstrate the benefits of multi-component interventions for patient outcomes, service use and cost, there is less evidence about the successful implementation of such models into routine care. Changing clinician behaviour (within both primary care and specialist sectors) and maintaining systems that support and promote such changes is believed to be key to the implementation of new models of care [76]. The "voltage loss" over time of such interventions is a clear risk [50].
There are a number of important limitations to this review. A number of compromises to standard methods for systematic review were made. The shortened timescale did not permit activities to be undertaken sequentially and so activities overlapped and material was analysed as it became available. We were only able to examine a small selection of local grey literature. Particular importance was placed on published systematic reviews and the search focussed on key questions that were not addressed in those reviews, chiefly shared care for those with severe and persistent mental disorders. Despite these limitations we attempted to ensure high standards of replicability and transparency through defined inclusion and exclusion criteria [4] as detailed in Additional file 2.
It was not possible to undertake meta-analytic evaluation of the strength of evidence as studies investigated complex interventions, with varying levels of attention to the methodological and statistical issues [77]. Second, while papers often focused on specific desirable clinical outcomes, a detailed description of the service implementation process was often poorly reported. This is a key requirement for the translation of such findings to practice.
Conclusions
From many angles, it is imperative to improve the links between primary care and specialist mental health services. When joint primary and specialist level collaborative care models have been evaluated using RCT designs, a range of clinical and service benefits are reported, particularly in the primary care management of depression and anxiety disorders.
The available evidence provides only limited support for shared care models for the treatment of persistent psychotic disorders. While a few robust and innovative studies have been undertaken with this population further studies are needed, including research that encompasses diverse geographic and health service contexts.
Some core components of shared care warrant further targeted research (e.g. the specific functions and roles of mental health linkage workers). Demonstration projects with detailed and innovative evaluative designs are needed to understand better these core elements and the processes that underpin effective shared care, particularly their capacity to be translated to routine clinical practice.
The strategies proposed in this review pose substantial implementation challenges for any health service, yet are critical to ensuring that shared care services are better structured to achieve sustained improvements in mental health care.
