Our Work

OpenApp delivers its clients with robust, customized registries for both clinically entered/ patient entered applications. We work with our clients to develop a registry that caters to their specific needs on our refined software that can be used for data collection on any condition or procedure.



A pan European Registry solution spanning 33 countries and 42,000 patients. The European Cystic Fibrosis Society Patient Registry collects demographic and clinical data from consenting people with cystic fibrosis (CF) in Europe, in accordance with agreed inclusion criteria and definitions. The information is used to measure, survey and compare aspects of CF and its treatment in participating countries, to deepen our understanding of CF, to improve standards of care, to provide data for epidemiological research and to facilitate public health planning.



The Irish National Orthopaedic Register (INOR) is a secure web-based, real time (live) system used to collect demographic, clinical and implant component data on patients admitted to hospital for primary and revision hip and knee surgery in hospitals nationally. INOR breaks ground in a number of areas; it is a secure system which provides traceability of components, while protecting the privacy of non-consented patients. Additionaly, an Arthroplasty first, it records real-time barcode scanning in theatre.


CATS Foundation

Tay Sachs and Sandoff disease are complex illnesses which affect a range of people. An individual diagnosed with either disease will suffer a relentless deterioration of mental and physical abilities. CATs Foundation is a registry over two countries, it’s main objective is to gather data and to encourage pharma involvement.

Alpha One

Alpha 1 Foundation

Alpha-1 antitrypsin deficiency (Alpha-1 for short) is a genetic condition where the body does not produce enough Alpha1 antitrypsin protein. People born with Alpha-1 can develop lung, liver, or in rare cases skin problems.Collaborating with the Alpha-1 Foundation, OpenApp created a patient registry for the foundation.



The Cystic Fibrosis Registry of Ireland (CFRI) is a customized extension to the European Cystic Fibrosis Society (ECFS) platform. The information is used to measure, survey and compare aspects of CF in Ireland. Including all of the ECFS functionality, the Irish registry had increased requirements including deeper encounter data collection needs and advanced reporting requirements. The information is used to support new health technology assessments, compile reports for the EMA and support health planning in Ireland and the EU.
