[Pharmaco-therapeutic evaluation of medical treatments of adult autistics and multi-handicapped patients in a public mental health unit].
BACKGROUND
This paper presents a survey conducted on a population of multi-handicapped patients and autistic adults hospitalised long term in the Paul Guiraud mental health Hospital in Villejuif France.


OBJECTIVE
The aim of the survey is to deepen the knowledge of the treatments for this specific population.


METHODS
A preliminary medical investigation was conducted on the population in order to target different groups of patients. Once patients had listed and defined their medical needs, prescriptions were analysed to assess whether clinical characteristics had an impact. Thus, the analysis of treatments was carried out for the 57 patients (14% of the hospital population) and compared to other investigations conducted on the population commonly hospitalised in Psychiatry. The evaluation of the treatments was obtained through a questionnaire which enabled us to target the therapeutical goals and to obtain additional clinical information. The drugs with a high rate of prescription were compared between the autistic group and the multi-handicapped group. The important comorbidity and the multi-symptomatology of autism often involves the polymedication of these patients (8+/-0.8 drugs per patient).


RESULTS
Fifty per cent of the treatments are referred to as somatic treatments. The average length of stay (22.3 years) and the high average age are aggravating factors for polymedication. The average number of psychotropic molecules also appears higher than in the populations studied in the literature. The heterogeneity of clinical forms of autism and polyhandicap encourages prescribers to multidrug therapy. The prescriptions usually remain stable (17.5% of psychiatric treatment is adapted and only 7% of somatic treatment). Epilepsy and constipation are the main treated somatic disorders. In psychiatry, the oral route is the privileged route of administration (81% of treatments) with, more specifically, the use of drinkable solutions for the psychiatric treatment. Neuroleptic drugs are the basic treatment of these patients (82% of prescriptions). The aim of the prescription of neuroleptics is essentially to obtain behavioural or antipsychotic sedation. Cyamemazin is the most prescribed drug (46% of neuroleptic prescriptions), mainly for its anxiolytic effects. Co-prescription is frequent (55.3%) and corresponds to 53% of co-prescriptions of an association of phenothiazine and butyrophenone. Doses are high, which implies the prescription of treatments against the neuroleptics side-effects (86% of patients have such a prescription). The rate of prescriptions of the other psychotropic drugs (hypnotics, anxiolytics, etc.) is approximately equivalent between our population and the "classical" hospitalised psychiatric population, except for antidepressants (7% of prescriptions) because the differential diagnosis is difficult in these patients. Nearly 60% of patients have prescriptions of hypnotic drugs. However, this figure is tempered by prescriptions of drugs "if necessary" in two-thirds of the cases. Finally, only 30% of patients have systematic hypnotic prescriptions.


CONCLUSIONS
Although autistics are clinically different from multi-handicapped patients, no statistically significant difference was demonstrated in their prescriptions, which implies a similar pharmacological management. It is difficult to clearly distinguish these two populations only according to the type of drugs used and the doses prescribed.
