## 1 Introduction
### Introducing DPIA ClickGo  
Despite the challenges involved in the DPIA process, the existence of commonalities among many DPIAs provides an opportunity for optimization. Recognizing that multiple DPIAs often encounter similar risks and comparable risk-mitigating strategies, we identified the potential to streamline the process and enhance efficiency, as described in Article 35(1), sentence 2 of the GDPR. As a result, we dedicated our efforts to develop an innovative and user-friendly solution to facilitate the generation of a DPIA: the open-source \"plug-and-play\" tool, DPIA click&go (in German _DSA click&go_, translated from the German word _Datenschitzfolgenabschutzung--DSAF_).  
The DPIA click&go tool empowers users to navigate the intricacies of conducting a DPIA by offering a systematic approach. In a user-friendly interface, individuals can conveniently select risks from a pre-defined, institute-specific pool of overarching risks and their corresponding sub-risks (Step 1). The pool also contains risks that are project-type-specific, i.e., different use cases can be selected and combined. Subsequently, the tool automatically generates an evaluation matrix to assess the probability of occurrence and the severity of harm because the risk assessment in this regard is initially regarded as comparable in every project (Step 2). This matrix serves as a foundation for further analysis and decision-making.  
To address the identified risks effectively, DPIA click&go also provides users their institute-specific, curated risk-mitigating measures, commonly known as technical and organizational measures (TOMs, Step 3). These suggested TOMs, based on industry best practices and relevant institutional regulations, give users a starting point for designing their own data protection strategies.  
As the individual DPIA progresses, users can expand on the selected risks and associated TOMs, tailoring them to suit the specific characteristics of their project. The tool allows users to conveniently insert these customized elements as text blocks into the tool, which then generates a Word document, thereby significantly reducing the time and effort required to draft the DPIA report.  
A comprehensive literature review on PubMed and Google Scholar, spanning from 2017 to the present, explored GDPR implementation in various institutes and tools for DPIA generation. Our search encompassed terms like GDPR, data protection impact assessment, and DPIA, revealing works addressing GDPR's technical requirements [12], evaluatingprivacy and ethics in health research networks [13], formal descriptions [14], mathematical abstractions [15], application-specific frameworks [16], evaluation frameworks for existing software [17], and case studies for step-by-step DPIA generation [18]. Notably, no existing tool offers a versatile, semi-automated approach applicable across diverse healthcare projects, as proposed here.  
In this work, we will demonstrate using an example project how the here-introduced DPIA click&go tool can be highly effective in the local data protection context of our institute to significantly simplify the creation of a DPIA. Furthermore, the DPIA click&go tool can serve as a guiding example for other national institutes, as well as for other countries facing similar challenges.  
Emphasizing the challenges, rationale, and contributions of our work, this introduction sets the stage for a comprehensive exploration of the DPIA click&go tool and its implications in the realm of data protection and medical research.
