Our analysis presents a case study on the impacts of Health Care Home (HCH) – a large-scale technology-based healthcare innovation in New Zealand’s primary healthcare system. For our analysis, we link the registered population of health practices within the Wellington region to administrative hospital admission data for quarterly periods between 2014 and 2017. By employing variation in the timing of HCH implementation across practices (selected via propensity score matching), we estimate differences-in-differences models to investigate the effects of the intervention on multiple patient outcomes. Additionally, we incorporate a number of empirical specifications to test the robustness of estimates. HCH results in a statistically significant reduction in the likelihood of emergency department (ED) presentations by 6–8 %, with no significant impacts on other health outcomes. The impact on ED presentations aligns with the expectation that the HCH intervention would produce downstream effects of a reduced economic burden on public hospital services.
This study empirically examines the impact of warrantless arrest laws (designed to deter domestic violence) on multiple youth outcomes. Utilizing variation in the timing of implementation of the laws across states, and employing a difference in differences framework, we examine both the direct and indirect impacts on youth in the United States. There appears to be no significant direct link between warrantless arrest laws and domestic violence-related homicides. However, on the indirect front, we do find strong evidence that implementation of the arrest laws results in a drop in the probability of youth experiencing suicidal ideation. This analysis also accounts for important heterogeneities in laws across states, and our findings are robust to multiple sensitivity checks, aimed at addressing key threats to identification.
