[Articles] Return on investment of enhanced primary youth mental health services in a large Canadian urban centre: a retrospective cohort study
Abstract
Consistent with principles of early intervention in mental health, ACCESS Open Minds implementation resulted in improved or equivalent outcomes but also shifted care towards community-based settings, with substantial net cost savings. These cost savings can be realised if novel services identify and treat not only new cases but also include those who were previously intensive users of standard services. The long-term return on investment of enhanced primary youth mental health models such as ACCESS Open Minds will likely rest on their commitment to including this population.
Clinical relevance
Does an enhanced primary-care youth mental health service model (ACCESS Open Minds) produce a positive return on investment compared to standard community mental health services, and does service utilisation shift from institutional to community-based settings among help-seeking youth aged 15–25? __SNAPSHOT__ {"studyDesign":"Retrospective cohort study with difference-in-differences analysis, propensity score matching, and sensitivity analyses","setting":"Edmonton, Alberta, Canada — largest urban site (metropolitan population ~1.3 million) of the pan-Canadian ACCESS Open Minds network; community mental health services setting","sampleSize":"n=10,632 total (ACCESS Open Minds: n=1,415; standard community mental health services: n=9,217)","population":"Help-seeking youth aged 15–25 years with any mental health problem presenting between April 6, 2016, and September 30, 2019; mean age 20.1 years (ACCESS Open Minds) vs. 19.3 years (comparator); 54.6% female, 45.4% male; no ethnicity data available in the administrative dataset","intervention":"ACCESS Open Minds enhanced primary-care youth mental health service — a service transformation model featuring early case identification, rapid access (initial evaluation within 72 hours), youth-friendly community-based settings, loosened entry criteria, family inclusion, reduced administrative barriers, and evidence-informed interventions within 30 days","comparator":"Non-transformed standard community mental health services in the same urban centre","primaryOutcome":"Service utilisation and corresponding return on investment (net cost savings per person per year after accounting for programme implementation and operating costs), including shifts in the type and setting of mental health care delivery","followUp":"1 year post-exposure to the ACCESS Open Minds service (within the April 2016–September 2019 observation window)","fundingSource":"Canadian Institutes for Health Research (CIHR) Strategy for Patient-Oriented Research, jointly funded with the Graham Boeckh Foundation (government and non-profit)"}
Key findings
The ACCESS Open Minds intervention was associated with improved or equivalent clinical outcomes compared to standard services, while also shifting care from institutional settings (hospitalizations, emergency department, physician, and publicly funded residential visits) toward community-based services. After accounting for programme implementation and operating costs, net savings were reported as CAD $4,355 per person per year, corresponding to approximately $9.70 saved for every dollar invested (return-on-investment ratio of ~9.7:1). Specific p-values, confidence intervals, and absolute utilisation rates for individual service categories are not reported in the available abstract. Notably, the ACCESS Open Minds Edmonton cohort included a higher proportion of youth with substantive symptom burden, functional difficulties, and prior intensive use of hospital, emergency, and residential services relative to the comparator group — i.e., no evidence of 'cream-skimming' was found. The analysis used a difference-in-differences framework with propensity score matching to reduce selection bias, though residual confounding cannot be excluded in this observational design. NNT/NNH are not applicable to this economic evaluation. No specific adverse events were reported.
Practice implications
This study establishes that an enhanced primary-care youth mental health service model, when implemented at scale in a large Canadian urban centre, can simultaneously achieve improved or equivalent clinical outcomes and generate substantial net cost savings by redistributing care from high-cost institutional settings to lower-cost, community-based environments. The finding that cost savings were achieved despite serving a clinically complex population — including prior intensive users of hospital and emergency services — is particularly important: it refutes the concern that favourable economic outcomes in such programmes are driven by preferential intake of lower-acuity youth ('cream-skimming'). What the study does NOT establish: long-term (beyond 1 year) sustainability of cost savings; generalisability to smaller urban, rural, or non-Canadian health systems; subgroup-level efficacy by diagnosis, ethnicity (not collected), or severity stratum; or whether findings would replicate in systems with different funding structures. The study is limited to an abstract (full-text access not available for review), and specific statistical parameters (confidence intervals, p-values) for key effect estimates could not be verified. Practice implications should be interpreted with appropriate caution given the observational design, single-site setting, and the structural differences between Canadian public health financing and other health systems. __LIMITATIONS__ Observational retrospective cohort design — randomisation was not performed; residual confounding cannot be excluded despite propensity score matching and difference-in-differences methodology.,Single large urban site (Edmonton, AB) limits generalisability to rural, remote, Indigenous-community-only, or non-Canadian settings.,No ethnicity data were available in the administrative dataset, precluding equity-stratified analyses.,Follow-up limited to 1 year post-exposure; long-term cost trajectories and clinical outcomes beyond this window are unknown.,Administrative data used for cost estimation may not capture all relevant service utilisation or indirect costs (e.g., productivity losses, caregiver burden, criminal justice contacts).,The comparator group (standard community services) was not randomly assigned; despite propensity score matching, systematic differences in referral patterns, clinical complexity, or help-seeking behaviour may persist.,Only the abstract is currently available for independent review; full statistical outputs (confidence intervals, p-values for individual cost components) could not be verified.,Government and non-profit funding reduces industry bias risk, but the investigators are deeply embedded in the ACCESS Open Minds network, introducing potential allegiance effects.,The return-on-investment figure of ~$9.70 per dollar invested is a system-level estimate contingent on programme implementation costs that may vary substantially across sites and jurisdictions. __BOTTOM_LINE_CATEGORY__ potentially_practice_informing __BOTTOM_LINE__ In a large Canadian urban cohort of 10,632 help-seeking youth, the ACCESS Open Minds enhanced primary-care mental health model shifted care from costly institutional settings to community-based services, yielding improved or equivalent clinical outcomes and a net saving of approximately CAD $4,355 per person per year (~$9.70 saved per dollar invested), even when serving clinically complex youth previously reliant on intensive services. These findings suggest that inclusive enhanced primary youth mental health services — ones that explicitly engage high-acuity users rather than restricting intake to mild-to-moderate presentations — are necessary to realise meaningful economic returns. Confirmation across additional sites, health systems, and longer time horizons is needed before broad policy adoption, but the data provide the strongest economic evidence to date supporting investment in this model.
