Overview

ESD - Evaluation Software Development Rumpold & Holzner OG is an Austrian software company that develops and operates the Computer-based Health Evaluation System (CHES). According to its official website, CHES is an eHealth platform for patients, doctors and nurses that provides electronic data capture, including electronic questionnaire administration and electronic case report forms, as well as data storage and data analysis. The company positions itself as a research solution provider for multicenter studies and registries, with a tight connection to scientific research and to users in daily clinical routine. The CHES platform is used to collect electronic patient-reported outcomes (ePROs). The official website states that the company has supported 374 scientific papers, collected 1,153,251 ePROs, handled 44,460 tickets and issued 1,024 releases. These figures illustrate a long-running, research-oriented software operation rather than a consumer app. Beyond the core CHES platform, ESD describes applications for telemedicine and online consultations, machine-learning-based processing of large and disparate data sources, and an electronic clinical trial management system (eCTMS) developed together with SynapCon. The eCTMS is presented as designed to meet high standards of good clinical practice and regulatory compliance, combining IT and clinical research experience. ESD's offering is aimed at healthcare providers, clinical researchers, hospitals and study sponsors who need validated electronic data capture and patient-reported outcome measurement. The company also provides scientific consulting and project management support. Its website is ches.pro, and the brand is closely associated with the CHES product name in the clinical research and eHealth community.

The website describes applications for telemedicine and online consultations, noting that telemedicine is increasingly changing how patients access medical care and expertise.

In addition, ESD and SynapCon jointly designed an electronic clinical trial management system (eCTMS) intended to meet high standards of good clinical practice and compliance, drawing on both parties' experience in IT and clinical research. ESD also provides scientific consulting and project management support. The company's brand is closely tied to the CHES product name, and its website is ches.pro.
