In WP5 “Evaluation of the effectiveness and cost-effectiveness of the intervention”, the statistical analyses of demographic, socioeconomic and clinical data (collected during WP4's clinical study) will be conducted to evaluate the blended collaborative care (BCC) approach.

The Department of Medical Statistics at the University Medical Centre Göttingen is responsible for the statistical aspects of the clinical trial and the statistical analyses of clinical data. The Institute of Health Economics and Clinical Epidemiology at the University of Cologne performs the cost-effectiveness evaluation.

The Health Economics team will examine the economic impact of BCC implementation from a provider perspective, taking into account participating countries. A health economic analysis ensures that the resources available in the healthcare system are used as efficiently as possible. This enables the greatest possible benefit for patients regarding the treatments used in their care, given possible cost constrains. WP5 is now focused on finalizing all materials that are necessary to collect country-specific cost and pricing information.

The Department of Medical Statistics took responsibility for the statistical aspects of the clinical trial design and will perform the statistical analyses necessary to evaluate the clinical effectiveness of the BCC approach. To improve reproducibility, transparency, and validity among clinical trials a Statistical Analysis Plan (SAP) is necessary. Our team of biostatisticians are currently preparing the SAP, which pre-specifies and describes statistical methods for the analysis of the trial data. Lastly, the team has contributed to the publication of the study protocol, already outlining the planned analyses.
