This study describes a one year follow-up study of 53 ambulatory patients treated with case management oriented care. These patients, characterized by a chronic evolution for an average of 10 years, presented after a one year period a significant improvement of different symptomatic parameters (positive and negative psychotic symptoms). Psychosocial adaptation was also improved for their dependency, their activity and the amount of their social contacts. These results underline the usefulness of case management, which permits an optimal use of available therapeutic facilities. Moreover, the setting of such a program allows a more specifical treatment of this category of patients.
