An effective intervention delivered at sub-therapeutic dose becomes an ineffective intervention

Individual placement and support: History, current status, and future directions

Over the past three decades, Individual Placement and Support (IPS) has emerged as a robust evidence-based approach to helping people with severe mental illnesses, such as schizophrenia, bipolar disorder, and major depression, to obtain and succeed in competitive employment. This review addresses the history, principles, research, and future directions of IPS. It covers current evidence on employment outcomes, cost-effectiveness, and nonvocational outcomes. It also describes current attempts to extend IPS to new populations. The authors provide an overview of numerous systematic reviews and meta-analyses of randomized controlled trials involving people with serious mental illness. For studies addressing nonvocational outcomes and new populations, the review uses best available evidence. Published reviews agree that IPS enables patients with serious mental illness in high-income countries to succeed in competitive employment at a higher rate than patients who receive other vocational interventions. Within IPS programs, quality of implementation, measured by standardized fidelity scales, correlates with better outcomes. Employment itself leads to enhanced income, psychosocial outcomes, clinical improvements, and decreased mental health service use. As IPS steadily spreads to new populations and new settings, research is active across high-income countries and spreading slowly to middle-income countries. IPS is an evidence-based practice for people with serious mental illness in high-income countries. It shows promise to help other disability groups also, and emerging research aims to clarify adaptations and outcomes.

Modification of the Individual Placement and Support Model of Supported Employment

Individual placement and support (IPS) is a robust evidence-based model of supported employment for people with mental health conditions that has been implemented in high-income countries. The model is now being extended to new populations and settings, often with modifications. Current evidence indicates that minor modifications may increase fit, major alterations of core principles generally reduce effectiveness, and augmentations have mixed success. The authors recommend that those who implement IPS adhere to its core principles whenever possible, use standardized methods to document and assess modifications, and follow basic scientific procedures to develop, measure, and evaluate modifications before recommending policy changes.

A structured mixed method process evaluation of a randomized controlled trial of Individual Placement and Support (IPS)

Background

Individual Placement and Support (IPS) is an evidence-based work rehabilitation program helping people with moderate to severe mental illness to obtain ordinary employment. Although IPS has proven superior to other work rehabilitation programs, in many studies, the majority of the participants remain unemployed. Structured process evaluations of IPS that use mixed methods are scarce, although they could identify implementation aspects that may enhance its effect. The aim of the current study is to assess reach, fidelity, and identify barriers and facilitators to implement IPS.

Methods

The process evaluation was conducted alongside a randomized controlled trial including six IPS centers, comparing IPS with treatment as usual in a population of patients in treatment for moderate to severe mental illness. Mixed methods were used in the process evaluation, including focus group interviews with service providers, individual interviews and survey data from participants, and fidelity reviews using the validated IPS Fidelity Scale.

Results

The intervention reached the intended target group. All centers reached fair to good fidelity according to the IPS Fidelity Scale within the project period (range 97–109, SD 8.1) (see Table 5). Certain fidelity items indicated implementation issues related to employer contact, community-based services, and integration with health services. Survey data showed that less than half of the participants regarded their illness as a barrier for participating in IPS and that freedom of disclosure was important. Participant interviews gave further insight into the role of the IPS specialist, emphasizing their availability and consistent job focus.

Conclusions

Indications of implementation challenges across centers during the first year suggest special attention should be given to these aspects in an early phase to ensure higher fidelity from the start and thus enhance the effectiveness of IPS. The IPS specialist played an important role for participants and was described as positive, pushing in a positive way, and encouraging. More knowledge on the characteristics of successful IPS specialists could further enhance the effectiveness of the intervention.

Trial registration

The study was registered on clinicaltrials.gov prior to the inclusion period (reg.no: NCT01964092, registered 17/07/2013).

Barriers and facilitators to the implementation of individual placement and support (IPS) for patients with offending histories in the community: The United Kingdom experience

Introduction

We aimed to identify the barriers and facilitators to the implementation of a high fidelity individual placement and support service in a community forensic mental health setting.

Method

In-depth interviews were conducted with clinical staff ( n = 11), patients ( n = 3), and employers ( n = 5) to examine barriers and facilitators to implementation of a high fidelity individual placement and support service. Data was analysed using thematic analysis, and themes were mapped onto individual placement and support fidelity criteria.

Results

Barriers cited included competing interests between employment support and psychological therapies, perceptions of patients’ readiness for work, and concerns about the impact of returning to work on welfare benefits. Facilitators of implementation included clear communication of the benefits of individual placement and support, inter-disciplinary collaboration, and positive attitudes towards the support offered by the individual placement and support programme among stakeholders. Offences, rather than mental health history, were seen as a key issue from employers’ perspectives. Employers regarded disclosure of offending or mental health history as important to developing trust and to gauging their own capacity to offer support.

Conclusions

Implementation of individual placement and support in a community mental health forensic setting is complex and requires robust planning. Future studies should address the barriers identified, and adaptations to the individual placement and support model are needed to address difficulties encountered in forensic settings.

Supported employment for persons with serious mental illness: current status and future directions

The individual placement and supported (IPS) model of supported employment is the most empirically validated model of vocational rehabilitation for persons with schizophrenia or another serious mental illness. Over 18 randomized controlled trials have been conducted throughout the world demonstrating the effectiveness of supported employment at improving competitive work compared to other vocational programs: IPS supported employment is defined by the following principles: 1) inclusion of all clients who want to work; 2) integration of vocational and clinical services; 3) focus on competitive employment; 4) rapid job search and no required prevocational skills training; 5) job development by the employment specialist; 6) attention to client preferences about desired work and disclosure of mental illness to prospective employers; 7) benefits counseling; and 8) follow-along supports after a job is obtained. Supported employment has been successfully implemented in a wide range of cultural and clinical populations, although challenges to implementation are also encountered. Common challenges are related to problems such as the failure to access technical assistance, system issues, negative beliefs and attitudes of providers, funding restrictions, and poor leadership. These challenges can be overcome by tapping expertise in IPS supported employment, including standardized and tested models of training and consultation. Efforts are underway to increase the efficiency of training methods for supported employment and the overall program, and to improve its effectiveness for those clients who do not benefit. Progress in IPS supported employment offers people with a serious mental illness realistic hope for achieving their work goals, and taking greater control over their lives.

An update on supported employment for people with severe mental illness

PURPOSE OF REVIEW

Individual Placement and Support (IPS) is an effective intervention for helping people with severe mental illness obtain competitive employment, yet it has not been widely implemented. This review will examine and summarize the latest research on IPS.

RECENT FINDINGS

As the effectiveness of IPS has been well established in the literature, newer research is exploring nonvocational outcomes, such as quality of life and mental health services utilization and expanding the reach of IPS to include different countries and different population groups. There is also a growing literature exploring the cost-effectiveness of IPS compared with traditional vocational services, which has favored IPS. By far, the area of research that has expanded the most is aimed at enhancing IPS outcomes, at both the intervention level and the client level. Researchers are exploring the variance in IPS outcomes as a means of increasing competitive employment rates with IPS.

SUMMARY

Although the field of research continues to expand, it is clear that many barriers remain to broad implementation of IPS. The solution goes beyond further research and involves policies and practices that support a recovery oriented mental healthcare system.

Perspectives on Employment Integration, Mental Illness and Disability, and Workplace Health

This paper reviews the literature on the interplay between employment integration and retention of individuals diagnosed with mental health and related disability (MHRD). Specifically, the paper addresses the importance of an integrative approach, utilizing a social epidemiological approach to assess various factors that are related to the employment integration of individuals diagnosed with severe mental illness. Our approach to the review incorporates a research methodology that is multilayered, mixed, and contextual. The review examines the literature that aims to unpack employers’ understanding of mental illness and their attitudes, beliefs, and practices about employing workers with mental illness. Additionally we offer a conceptual framework entrenched within the social determinants of the mental health (SDOMH) literature as a way to contextualize the review conclusions. This approach contributes to a holistic understanding of workplace mental health conceptually and methodologically particularly as practitioners and policy makers alike are grappling with better ways to integrate employees who are diagnosed with mental health and disabilities into to the workplace.

The cost-effectiveness of supported employment for adults with autism in the United Kingdom

Adults with autism face high rates of unemployment. Supported employment enables individuals with autism to secure and maintain a paid job in a regular work environment. The objective of this study was to assess the cost-effectiveness of supported employment compared with standard care (day services) for adults with autism in the United Kingdom. Thus, a decision-analytic economic model was developed, which used outcome data from the only trial that has evaluated supported employment for adults with autism in the United Kingdom. The main analysis considered intervention costs, while cost-savings associated with changes in accommodation status and National Health Service and personal social service resource use were examined in secondary analyses. Two outcome measures were used: the number of weeks in employment and the quality-adjusted life year. Supported employment resulted in better outcomes compared with standard care, at an extra cost of £18 per additional week in employment or £5600 per quality-adjusted life year. In secondary analyses that incorporated potential cost-savings, supported employment dominated standard care (i.e. it produced better outcomes at a lower total cost). The analysis suggests that supported employment schemes for adults with autism in the United Kingdom are cost-effective compared with standard care. Further research needs to confirm these findings.

Difficulties in implementing supported employment for people with severe mental health problems

People with severe mental health problems have low rates of open employment. Despite good evidence for the effectiveness of Individual Placement and Support (IPS), these schemes are not widely implemented. Their implementation is hampered by clinician and societal attitudes and the effect of organisational context on implementing IPS schemes with sufficient fidelity.

Supported employment: cost-effectiveness across six European sites

A high proportion of people with severe mental health problems are unemployed but would like to work. Individual Placement and Support (IPS) offers a promising approach to establishing people in paid employment. In a randomized controlled trial across six European countries, we investigated the economic case for IPS for people with severe mental health problems compared to standard vocational rehabilitation. Individuals (n=312) were randomized to receive either IPS or standard vocational services and followed for 18 months. Service use and outcome data were collected. Cost-effectiveness analysis was conducted with two primary outcomes: additional days worked in competitive settings and additional percentage of individuals who worked at least 1 day. Analyses distinguished country effects. A partial cost-benefit analysis was also conducted. IPS produced better outcomes than alternative vocational services at lower cost overall to the health and social care systems. This pattern also held in disaggregated analyses for five of the six European sites. The inclusion of imputed values for missing cost data supported these findings. IPS would be viewed as more cost-effective than standard vocational services. Further analysis demonstrated cost-benefit arguments for IPS. Compared to standard vocational rehabilitation services, IPS is, therefore, probably cost-saving and almost certainly more cost-effective as a way to help people with severe mental health problems into competitive employment.

Generalizability of the Individual Placement and Support (IPS) model of supported employment outside the US

While reviews of controlled studies of the Individual Placement and Support (IPS) model of supported employment for clients with severe mental illness have documented its effectiveness in the US, its generalizability to other countries has not been systematically evaluated. This is the first review to compare US to non-US studies. We identified 15 randomized controlled trials of IPS programs, 9 in the US and 6 outside the US. We examined competitive employment outcomes, including employment rate, days to first job, weeks worked during follow-up, and hours worked. We also considered noncompetitive employment, program retention, and nonvocational outcomes. IPS programs had significantly better outcomes across a range of competitive employment indicators and higher retention in services than control groups. The overall competitive employment rate for IPS clients in US studies was significantly higher than in non-US studies (62% vs. 47%). The consistently positive competitive employment outcomes strongly favoring IPS over a range of comparison programs in a group of international studies suggest that IPS is an evidence-based practice that may transport well into new settings as long as programs achieve high fidelity to the IPS model, but further research is needed on international adaptations.

A randomised controlled trial of the efficacy of supported employment

OBJECTIVE

  Although numerous randomised controlled trials indicated the superiority of supported employment (SE), we still have too little evidence that SE is more effective than traditional vocational rehabilitation programmes (TVR) in Western European countries with highly developed social security and welfare systems, sophisticated rehabilitation programmes and high thresholds to the open labour market. The aim of this study is to prove the efficacy of SE in Switzerland.

METHOD

  Following a 2-week intake assessment, 100 unemployed persons with stabilised severe mental illness (SMI) were randomly assigned to either the SE programme (n=46) or to the most viable locally available TVR (n=54). Follow-up lasted 24 months.

RESULTS

  After the first year, the rate of competitive employment reached a mean level of 48.2% in the SE group and of 18.5% in the TVR group. 58.7% of the SE group were ever competitively employed as opposed to 25.9% of the TVR group. In the second year, SE group participants were competitively employed for 24.5 weeks as compared with 10.2 in the TVR group. The groups showed no significant differences in the non-vocational outcome criteria.

CONCLUSION

  The SE programme in Switzerland also proved more effective than TVR and seems to be applicable to the socio-economic context of Western European countries.

Educating healthcare professionals to act on the physical health needs of people with serious mental illness: a systematic search for evidence

Healthcare professionals in primary and secondary care should monitor the physical health of people with serious mental illness, yet in practice this does not appear to be a routine intervention. Our objective is to develop evidence-based training for healthcare professionals to enable them all to offer better physical care to this population. We performed a systematic search with the aim of evaluating the current evidence of the efficacy of education interventions. Search terms covered Severe Mental Illness, Physical Health and Education. The search yielded 147 papers, of which none were eligible for inclusion. A number of studies were excluded from this review as although there was an implicit education package provided to healthcare professionals, no information was reported on the outcomes of this education with regard to healthcare professionals' knowledge, attitudes and behaviours. The only information that these studies provided was patient-specific outcomes. It is vital that researchers start to publish details of healthcare professional education and their outcomes in physical health and serious mental illness research.
