Robert B. Penfold,Fang Zhang +1 more
TL;DR: A brief description of ITS is provided, including a fully implemented study of the impact of a program to reduce ADHD medication initiation in children younger than 5 years old and insured by Medicaid in Washington State, and why ITS is a useful tool for quality improvement.

Simulation-based power calculation for designing interrupted time series analyses of health policy interventions
TL;DR: The power to detect effect size 1.0 appeared to be reasonable for many practical applications with a moderate or large number of time points in the study equally divided around the intervention, and investigators should be cautious when the expected effect size is small or the number oftime points is small.

Unmet Need for Mental Health Care in Schizophrenia: An Overview of Literature and New Data From a First-Admission Study
TL;DR: A substantial level of unmet need for care is found among individuals with schizophrenia both at community level and in treatment settings, with more than half of the individuals with this often chronic and disabling condition receiving either no treatment or suboptimal treatment.
