What is this research about?
Achieving high-quality implementation is important to provide effective and consistent delivery of evidence-based health interventions. However, it can be difficult to measure fidelity to an evidence-based model due to insufficient resources for routine monitoring and a lack of tools that define the core components of a model of care along with performance criteria.
Early psychosis intervention (EPI) programs follow an evidence-based model of care that includes a team providing pharmacological and psychosocial interventions to support clients through recovery from a first episode of psychosis. In 2011, the Ontario Ministry of Health and Long-Term Care developed EPI Program standards. An EPI program fidelity measure that aligned with the Ontario Standards was published in 2016.
What did the researchers do?
Researchers worked with a volunteer sample of nine EPI programs across Ontario, recruited through an email call out to the Early Psychosis Intervention Ontario Network. They used the First Episode Psychosis Service Fidelity Scale (FEPS-FS) and rated EPI implementation across 31 items using a 5-point scale. A rating of 4 on an item indicated satisfactory performance.
Assessments included a program site visit by trained volunteer, peer assessors. The assessor teams included two EPI program staff and one evaluation specialist. During the two-day site visits, the assessors:
- interviewed staff, clients, and families
- reviewed client charts
- observed a team meeting
- reviewed all program documents, and
- examined administrative data.
Assessors developed preliminary ratings for each of the scale items, held consensus meetings with a fidelity expert to finalize the ratings and reported their findings back to the programs, with recommendations for improvement.
What did the researchers find?
Overall, the nine programs scored an average of 3.1 to 4.4 across the rated items and five programs exceeded a satisfactory performance rating of 4. Highest rated were items that assessed structural components of the model (e.g., “patient–provider ratio” and “assigned a case manager”) and prescribing practices. The lowest ratings were for items assessing provision of psychosocial treatments, including cognitive–behavioural treatment, supported employment, weight gain prevention, and substance use treatment.
Common challenges across programs were lack of manuals and protocols to standardize delivery, and inconsistent documentation. Smaller programs scored lower on weekly meetings and multidisciplinary teams, along with some psychosocial care items.
Limitations and next steps
The results of this study may not reflect the broader EPI sector in Ontario because of the small sample size and self-selected participation. While efforts were made to enhance rating consistency, inter-rater reliability was not assessed. Since Ontario standards include items that are not assessed in this scale (for example peer support), and the international scale includes items that are not included in Ontario EPI standards, further work is needed on the validity of the scale for Ontario practice.
How can you use this research?
This research can be used to help EPI programs routinely assess how well they are following EPI standards. Other sectors can also learn how to conduct fidelity assessments using volunteer peer assessors.
