Management and treatment of eating disorders in an Italian region

Eating disorders (ED) are an outstanding health problem in western countries, and bear significant mortality, e.g. anorexia nervosa (AN), and morbidity. The Liguria Region Health Department set up a study with the support of a number of specialists to investigate the number and characteristics of patients referred to institutions, how patients were managed, and the healthcare facilities and personnel involved.

The retrospective study required that all regional institutions, except two, involved in the treatment of ED during the year 2001 filled out a special questionnaire.

Twenty-one institutions (n=19 public, n=2 private) followed 1,220 patients with ED in the mentioned year. The prevalence of such disorders was 6 fold higher in females (1,054 F, 166 M; age range 12-32 years). Bulimia nervosa (BN) proved to be the disorder category most frequently observed (prevalence 59%) followed by AN (26%, p<0.0001) and ED not otherwise specified (EDNOS) (15%, p<0.0001). Most (approximately 90%) of these patients were managed in outpatient settings, and a multidisciplinary team approach was used in fewer than 20% of cases. Hospitalization (complete or partial) was required in 10.5% of patients: 7.1% for mental disturbances and 3.4% for severe malnutrition/electrolyte abnormalities. Fewer than one fourth of patients was admitted to two specialty units (one public and one private) for inpatients in our region with ED. Treatment provided in these centers included a specific nutritional rehabilitation program and psychologic/psychiatric care. Patients more severely underweight underwent nasogastric or parenteral feeding whenever deemed clinically appropriate. The grade of knowledge of ED by general practitioners/pediatricians and their links with trained centers were poor.

Although our data were obtained from a selected population, thus preventing epidemiological conclusions, they show that ED are a significant health concern in our region, with BN representing the most common disorder diagnosed in the different settings (general or specialized medical practices). Overall, the prevalence of such disorders was assessed as six fold higher in females than in males. The emerging issues to be improved are: i) poor level of communication among different specialists and subsequent scanty use of a multidisciplinary team approach in the management of ED ii) insufficient use of guidelines for the management of such disorders iii) paucity of specialty institutions for inpatients with ED iv) inadequate knowledge of the problem by primary care physicians and the community, and poor links with the healthcare institutions that might help.
