title: Trends in adult home parenteral nutrition in Spain. 1992-2003.
abstract: There are very few data on trends in prevalence in home parenteral nutrition (HPN) in different countries. NADYA is the committee of the Spanish Society for Parenteral and Enteral Nutrition that takes care of the Spanish registry since 1992.
  
  
  METHODS
  A 12-year retrospective study of the activity of the registry was performed. The data were extracted from the NADYA's database as well as from the publications and abstracts reported on a yearly basis since 1992. Data on years 1993 and 1997-9 were not available.
  
  
  RESULTS
  Yearly prevalence has more than doubled to 86 patients since 1992. The number of reporting centres went up to 17 in 2003 (10 centres in 1992) As an average, the number of patients per centre is 5. The prevalence in 2003 was 2.15 patients per million inhabitants. There are trends to increasing age at the time of the first indication (42 years in 1992; 51 in 2003). Ischemic and thrombotic vascular diseases were the most common underlying diagnosis in adults. Tunnelled central venous catheters were chosen in 2/3 of the patients. Only around 17% of the patients received support from home delivery companies (11% in 1992) There were more than 1 complication per patient and year, mostly HPN-related.
  
  
  CONCLUSIONS
  We found a steadily increase in the number of reported patients and reporting centres over time. Prevalence went up to 2.15 patients per million inhabitants in 2003, still far behind the figures from other western countries. The NADYA registry allows a close follow-up of the evolution of HPN in Spain.
