The limited number of extramural residential facilities in the rural areas of Greece leads in the diminished effectiveness of the follow-up of the psychotic patients and the relapses of their condition. The goal of our study was to investigate the factors involved in the number and duration of the relapses, as well as the role of the intervention of the Ambulatory Mobile Units in modifying these parameters.

By using different statistical techniques 45 patients, aged between 17-67, were studied. In a 5-year follow-up, parameters like the number of relapses and their duration were correlated with socio-demographic variables and parameters concerning the personal and family background of the patient. A standard team consisting of an experienced psychiatrist-supervisor, other psychiatrists, trainees, psychologists, social workers and nurses were collaborating with the patients.

The number of relapses was correlated with:

1. a) The social abilities of the patients

2. b) The ability to cope up with their disease

3. c) Their age

4. d) The duration of their previous hospitalizations

5. e) The compliance with the suggested therapy

6. f) The presence of positive psychiatric anamnesis in the patient's family

7. g) The employment status

The duration of the relapses was correlated with:

1. a) The social achievements of the patient

2. b) Their employment status

3. c) Their leisure time activities

4. d) The frequency of their follow-ups

5. e) The presence of positive psychiatric family background

The Ambulatory Mobile Unit plays an essential role in the number and duration of the relapses.
