The implementation of the Object Management Group Healthcare Domain Task Force specification is very complex and
time consuming. Most healthcare institutions lack professionals with the necessary time, knowledge or experience to
understand and adapt the specification to the needs of the institution. In this paper we propose a framework that
facilitates the development of Clinical Image Access Service (CIAS) and Clinical Observation Access Service (COAS)
using Java. The framework hides the inherent complexity of ORB initialization, object reference and object persistence,
allowing the implementers to focus on the access to the information that will be made available by the HDTF services.
The framework is based on a delegation scheme for the main components of the CIAS and COAS specification. The
framework handles tasks such as object initialization, registration, activation and deactivation which, otherwise, would
be responsibility of the implementers. The framework has been implemented using JacORB 1.4 although it can support
any ORB. The framework is being used to integrate different systems at the Heart Institute of Sao Paulo. The use of this
framework can ease the implementation and integration of distributed information systems. It will improve the quality of
healthcare services and allow interoperability between healthcare providers by the use of OMG growing standard in
medicine.
