Description of intervention(s) / exposure
A three-armed non-randomized controlled trial comparing the efficacy of the VIP to facilitate return to competitive employment following severe acquired brain injury (ABI) when delivered by local vocational rehabilitation (VR) providers (VIP-VR; Arm 1), compared to the existing direct service model delivered by a specialist VR unit (VIP-DS; Arm 2), and treatment-as-usual controls (TAU; Arm 3).
The VIP-VR Fast Track and New Track pathways are individually tailored to the specific needs of the client and the workplace, but comprise of the service actions of intake, information gathering, assessment, stakeholder engagement, goal setting, intervention, and evaluation/review. Intervention includes education, training, emotional/motivational support, as well as coordination, navigating, advocating, and collaboration among stakeholders.

The VIP is a model of service integration program, tailored according to the needs of the participant, co-ordinated and delivered by a team of providers working across organisations and levels of care. Processes for co-ordination will be arranged between providers at each site and varied as the participant progresses through the program.

The VIP will target individuals who have sustained a severe ABI and will be provided on an individual basis to participants and their employers. It consists of two return to work (RTW) pathways, with participants receiving the VIP (Arms 1 & 2) allocated to one of these intervention pathways depending on their specific employment circumstances:

Fast-Track pathway = targeting those with opportunity and capacity to resume work with their pre-injury employer.

RTW programs will follow a graduated approach, tailored to the needs of each participant and employer and include strategies to manage physical and cognitive effects of injury. Participants may be working suitable duties within their pre-injury position or an alternate position.

The VR provider will receive the referral from the local adult NSW Brain Injury Rehabilitation Program (BIRP) site. They will then contact the participant’s employer to confirm their support to proceed with RTW planning. Once a RTW plan has been established, the participant will commence working. There will then be a phase of monitoring and upgrading the RTW program lasting up to 6 months.

Individualised services provided as part of the Fast-Track pathway include:
• Functional and workplace assessment: Undertaken by the VR provider with the client with the employer as a workplace visit taking up to 3 hours in length
• Employer education: The VR provider will provide employer education by a phone call lasting 30 minutes
• RTW Plan development: The VR provider will meet with the client and employer for up to 1 hour 15 minutes to develop the RTW plan
• Implement graduated RTW program, including monitoring and upgrades: The VR provider will deliver monitoring and upgrades through a series of phone-based meetings with the client and employer up to 3 hours
• On-site reviews and support to client and employer: The VR provider will undertake up to 3 on-site visits to review progress and support the client and employer
• Confirm stability of placement, close file and handover for further monitoring if required: The VR provider will organize a final meeting (on-site or remote) with the client and employer, taking up to 30 minutes.


New Track pathway = a ‘pre-vocational’ intervention targeting individuals with extremely severe injury and without opportunity to resume pre-injury employment or unable secure available positions in mainstream employment., though a ‘place and train’ approach.

Specifically, participation in an unpaid work training placement will allow for practical assessment, development of work fitness and skills, and potentially opportunities to transition to paid employment or other work opportunities.

The VR provider will receive the referral from the local adult NSW Brain Injury Rehabilitation Program (BIRP) site. The participant and VR provider will identify suitable options for the work training placement through a vocational assessment, with input from their BIRP case manager, family, and other stakeholders. The VR provider will then source a host employer and conduct workplace assessments to confirm suitability. Unpaid work training placements of up to 12 weeks will be negotiated with host employers.

Individualised services provided as part of the New Track pathway include:
• Vocational assessment to establish goals: Undertaken by the VR provider with the client in the clinic taking up to 2 hours in length
• Canvassing employers for work training placements: Undertaken by the VR provider by phone up to 7 hours
• Workplace assessment: Undertaken by the VR provider and client in consultation with the employer as part of an on-site visit up to 1 hour
• Negotiate conditions of the placement: Undertaken by the VR provider and client in consultation with the employer as part of an on-site visit up to 1 hour
• On-site training and support (including travel training, etc): Undertaken by the VR provider and client on site for up to 2 hours
• Considering the need for equipment and/or training courses: Undertaken by the VR provider in a phone consultation with the client and the employer lasting up to 30 minutes
• Employer education and support: Undertaken by the VR provider in phone consultation with the employer up to 5 hours
• Monitor and upgrade work training placement (as required): Undertaken by the VR provider in phone consultation with the client and the employer up to 9 hours
• Finalise placement outcome and plan for onward vocational program: The VR provider will organize a final meeting (on-site or remote) with the client and employer, taking up to 30 minutes.

Arm 1 (VIP-VR), the VIP will be delivered across 3 regions (encompassing 8 Local Health Districts) of NSW. The primary service providers will be the local adult NSW Brain Injury Rehabilitation Program (BIRP) team partnered with a private VR provider. Staff involved in delivering the VIP will be appropriately qualified (i.e., tertiary qualification in an Allied Health discipline) and experienced in delivering VR.

In Arm 2 (VIP-DS), the same VIP program as listed above for Fast Track and New Track will be delivered by members of a specialist VR unit contained within a single BIRP service (Head2Work service at Liverpool Hospital) where VIP has already been established through a direct service model. Staff involved with delivering the VIP will be experienced Occupational Therapists at Head2Work and other Liverpool Hospital BIRP staff already familiar with the VIP model.

Comparator / control treatment
Specialist delivery of the VIP (VIP-DS – participants will complete the VIP through the existing direct service model at a specialist VR unit)
Treatment-as-usual control (TAU – participants with TBI from one of five non-participating NSW BIRP sites, matched to TBI cases in Arm 1 (VIP-VR) for age, sex, injury severity, time post-injury, education level, and pre-injury work status). These participants will not complete the VIP, but will have primary and secondary outcome measures collected.
Treatment as usual is not standardised and each of the control study sites have differences in their clinical practice. Typical actions would include referral of some clients with vocational potential to a local VR provider and in some units, in-house VR might be provided for a small number of high functioning clients returning to their previous employment.

The sample size was determined primarily based on funding allocation for the project rather than statistical considerations. Specifically, estimates of available funding for VR services led to a recruitment target of n=75 for the VIP-VR arm. Sample size for the VIP-DS and TAU arms will be contingent on the size and characteristics of the VIP-VR participants, as well as the study duration. Participants in the VIP-DS arm will be consecutive referrals to the Head2Work service undertaking the VIP over the study timeframe that meet the study eligibility criteria. The size of the TAU arm will depend on the number of TBI participants eventually enrolled in the VIP-VR arm (we estimate that around n=55 TBI participants will be enrolled in the VIP-VR arm, each of which will trigger enrolment of a matched TBI participant in TAU).

All analyses will be implemented on an intention-to-treat (ITT) basis. Baseline socio-demographic and injury-related characteristics of the three intervention arms will be compared using one-way analysis of variance (ANOVA) for normally distributed continuous data, Kruskal-Wallis tests for non-normally distributed continuous data, or chi-square tests of independence for categorical data.

The effects of the three intervention arms on the primary and secondary outcomes over time will be assessed using generalized and linear mixed effects modelling. Repeated measurements (i.e., three timepoints) will be nested at level 1 within each participant at level 2, such that variability between participants can be modelled using random effects. Fixed effects for each model will include: time (represented as two piecewise variables representing: (1) baseline to VIP completion, (2) VIP completion to 3 month follow-up), intervention arm (at level 2) and arm*time cross-level interactions. Any baseline characteristics identified as being statistically significant across intervention arms from univariate comparisons will also be considered as fixed effects. Each model will include a random intercept; random slopes corresponding to the piecewise time variables will also be considered. Alternate R-sided covariance structures (e.g., autoregressive(1)) will also be tested.

In each model, two simple effects contrasts will be defined to evaluate baseline differences between the intervention arms: (1) VIP-VR & VIP-DS vs. TAU, (2) VIP-VR vs. VIP-DS. Significant overall tests of arm*time interactions will be followed-up with up to four contrasts evaluating how the 2 between-group comparisons defined for the simple effect contrasts change (1) from baseline to VIP completion; and (2) from VIP completion to 3 month follow-up.

Overall model goodness-of-fit will be assessed using likelihood ratio tests, AIC and BIC statistics as appropriate. Fixed effects will be evaluated with Wald-type tests. Random effects will be evaluated via likelihood ratio tests.

A secondary analysis will evaluate whether the two VIP pathways (i.e., Fast-Track vs. New-Track) have differential effects on the study primary and secondary outcomes. To achieve this, participants in the VIP-VR and VIP-DS arms will be aggregated and re-categorized according to the VIP pathway undertaken. The same generalized and linear mixed effects modelling approach will then be repeated, with the intervention arm factor replaced by a VIP pathway factor.

Summary
Brief summary
People of working age who sustain a severe acquired brain injury (sABI) have low return to work (RTW) rates that range from 16-40%. The Vocational Intervention Program (VIP) was developed specifically to facilitate return to competitive employment after sABI. Unlike most vocational rehabilitation models available to people with sABI, the VIP focuses on building skills working towards gaining new employment in those unable to work, not just targeting a return to pre-injury employment in those who have the capacity to do so. This study will examine whether local vocational rehabilitation (VR) providers, partnered with local Brain Injury Rehabilitation Program sites, can deliver the VIP to people with sABI as effectively as a specialist VR unit. It will also examine whether the VIP leads to earlier and stronger return-to-work outcomes and improves quality of life and self-esteem compared to people with sABI that do not complete the VIP.
