Overuse of medical imaging and effects of payer-provider integration: quasi-experimental evidence from Finland.

Finnish Institute for Health and Welfare, PO Box 30, 00271, Helsinki, Finland.
Background: Healthcare expenditures have risen in middle- and high-income countries. One of the potential contributors is the overuse of diagnostics. I explore whether medical imaging is overused when privately owned clinics in Finland treat patients with voluntary private health insurance (VPHI).

The ICH E9 addendum on estimands in clinical trials provides a framework for precisely defining the treatment effect that is to be estimated, but says little about estimation methods. Here, we report analyses of a clinical trial in type 2 diabetes, targeting the effects of randomized treatment, handling rescue treatment and discontinuation of randomized treatment using the so-called hypothetical strategy. We show how this can be estimated using mixed models for repeated measures, multiple imputation, inverse probability of treatment weighting, G-formula, and G-estimation.

Applying the Social Representations Approach, a qualitative study of 10 focus group discussions (n = 39), was conducted in Singapore, Malaysia and the UK to explore how, and why racialised identity construction changed in each socio-political context. The study challenged two underlying assumptions in social psychology: (1) that the meaning of the racialised category holds constant across time and space, and (2) there exists a pan-racial identification among Asian identities, for example, which at times allows for racialised categories to be manipulated as variables.

Acquiring a second language creates intricate modifications in brain connectivity. Although considerable studies have evaluated the impact of second language acquisition on brain networks in adulthood, the results regarding the ultimate form of adaptive plasticity remain inconsistent within the adult population.

Objective: To develop a distributed algorithm to fit multi-center Cox regression models with time-varying coefficients to facilitate privacy-preserving data integration across multiple health systems.
Materials And Methods: The Cox model with time-varying coefficients relaxes the proportional hazards assumption of the usual Cox model and is particularly useful to model time-to-event outcomes. We proposed a One-shot Distributed Algorithm to fit multi-center Cox regression models with Time varying coefficients (ODACT).
