For a few years now, the mental health care organizations and the University Medical Center in the northern part of the Netherlands have joined forces in the ROM evaluation of service users with psychotic disorders. By means of a centralized Web-based ROM system, an evaluation is conducted for each service user at least annually. It consists of a physical examination (measuring weight, girth, height, and glucose levels) and multiple interviews and questionnaires, including the Health of the Nation Outcome Scale, Manchester Short Assessment of Quality of Life, Camberwell Assessment of Need, the Positive and Negative Syndrome Scale (PANSS), and a client satisfaction scale. Test parameters are uploaded by clinicians and research nurses into a central database through a link in the electronic patient file. An intelligent database management program presents the ROM results, summarizing all test outcomes in a letter addressed to both mental health clinicians and general practitioners. This letter, which can be accessed only via the secure environment of the electronic patient file, encourages clinicians to evaluate the treatment process together with their clients and, if necessary, to revise the treatment plan. The connection between the database server and the electronic patient file is secured by means of data encryption.
