Insights
This study details a compulsory re-feeding program for anorexia nervosa (AN) patients, successfully increasing BMI and utilizing percutaneous feeding tubes. The intensive program aims to stabilize patients for further psychotherapy.
Area of Science:
- Clinical Psychology
- Nutritional Psychiatry
- Gastroenterology
Background:
- Anorexia nervosa (AN) is a severe eating disorder with a high mortality rate.
- Extremely underweight patients require intensive interventions for stabilization.
Purpose of the Study:
- To describe a compulsory re-feeding program for severely underweight anorexia nervosa patients.
- To evaluate the short-term efficacy of this intensive treatment approach.
Main Methods:
- Mandatory inpatient status and compulsory re-feeding were implemented.
- Percutaneous gastric feeding tubes were used as needed to reach a target BMI of 17 kg/m².
- Data from 68 patients were analyzed.
Main Results:
- Mean BMI increased from 12.3 to 16.7 kg/m².
- Percutaneous tube feeding proved superior to other methods.
- Patients with the restrictive subtype showed better outcomes in some aspects.
Conclusions:
- An intensive care program for severe anorexia nervosa has been successfully established.
- The program effectively averts physical harm and prepares patients for further psychotherapy.
- This program is notable for its regular use of percutaneous feeding tubes.
Background:
Anorexia nervosa (AN) is associated with a high mortality rate. This study describes a compulsory re-feeding program established in Munich for extremely underweight patients.
Methods:
The contract between the patient and the therapeutic team included mandatory inpatient status, establishment of guardianship and compulsory re-feeding with a percutaneous gastric feeding tube, as indicated. The predefined target was a body mass index (BMI) of 17 kg/m(2). Data on the first 68 patients with AN are presented.
Results:
65 (95.6%) patients were female and mean age at admission was 26.5 ± 8.5 years. BMI increased from 12.3 ± 1.4 kg/m(2) at admission to 16.7 ± 1.7 kg/m(2) at discharge. Thirty-two (47.1%) patients had the restrictive subtype (ANR) and 36 (52.9%) had the binging and purging subtype (ANBP). Duration of illness before admission (p = .004), days of treatment until discharge (p = .001) and weight increase (p = .02) were significantly different between subgroups in favor of patients with ANR. Also, seasonal differences could be found. Comparison of feeding methods showed that percutaneous tube feeding was superior. Almost half of the patients were treated with psychotropic medication. To date, however, the number of patients included in this program is too small to assess rare complications of this acute treatment program and long term outcomes of AN.
Conclusions:
An intensive care program for severely ill AN patients has been successfully established. Besides averting physical harm in the short term, this program was designed to enable these patients to participate in more sophisticated psychotherapeutic programs afterwards. To our knowledge, this is the first such program that regularly uses percutaneous feeding tubes.
