The PFM accurately represents patient flow through the department and can provide simulated patient flow information on a variety of scenarios. It can effectively simulate changes to the model and its effects on patient flow.

Aim-To refine and psychometrically test the Am I ON TRAC for Adult Care questionnaire. Background. Inadequate transition to adult care for adolescents with special health care needs has been associated with greater risk of treatment non-adherence, lack of medical follow-up, increased morbidity and mortality. Presently there are no well-validated measures assessing adolescents' readiness to transition from paediatric to adult medical care. Design-Descriptive cross-sectional study.Methods-The Am I ON TRAC for Adult Care questionnaire was refined to improve the instrument's methodological soundness. A literature review informed the revisions. A convenience sample of 200 adolescents, 12-19 years, was recruited from four outpatient clinics at a paediatric hospital in Western Canada between April -June 2012. Construct validity was evaluated by Exploratory Factory Analysis; concurrent validity was assessed using the Psychosocial Maturity Index. Internal consistency was evaluated by computing Cronbach's alpha estimates.Results-Factor analysis of the knowledge items identified a 14-item unidimensional scale. Knowledge and behaviour sub-scale scores increased with age, with a stronger relationship between knowledge and age. Psychosocial maturity correlated with both sub-scale scores, but had CIHR Author ManuscriptCIHR Author Manuscript CIHR Author Manuscript a stronger association with behaviour. Psychosocial maturity and age had a weak but significant correlation suggesting age is a loose proxy for maturity. Only 27% of 17-year-olds, but 62% 18-year-olds, scored above the behaviour cut-off for transition readiness. Conclusion-TheAm I ON TRAC for Adult Care questionnaire is a psychometrically sound measure that has potential to be used as a readiness assessment tool in both clinical practice and research.
