Gastroparesis is an increasingly recognized disorder.
Its prevalence in the United States is unknown.
Dr Yize Wang and colleagues from Pennsylvania, USA examined the trends, characteristics, and outcomes of gastroparesis-related hospitalizations during 1995 to 2004.
|Gastroparesis as the primary diagnosis increased by 158%|
|The American Journal of Gastroenterology|
The publicly available Healthcare Cost and Utilization Project Nationwide Inpatient Sample comprises a nationally representative sample of 5 to 8 million hospitalizations per year.
The team identified gastroparesis-related hospitalizations using the International Classification of Diseases code 536.3 and compared with other hospitalizations.
The team used multivariate regressions to compare for differences in the outcomes including length of stay, total charges, and in-hospital deaths.
The researchers found hospitalizations with gastroparesis as the primary diagnosis increased from 3,977 in 1995 to 10,252 in 2004, an increase of 158%.
Hospitalizations with gastroparesis as the secondary diagnosis increased from 56,726 to 134,146, an increase of 136%.
The team observed that diabetes-related hospitalizations increased by 53%.
Hospitalizations with gastroesophageal reflux disease, gastric ulcer, gastritis, or nonspecific nausea/vomiting as the primary diagnosis increased up to 76%.
Of the 5 upper gastrointestinal conditions studied as the primary diagnosis, gastroparesis had the longest length of stay.
The research team noted that gastroparesis had the highest or second highest total charges in 2004, with similar results in 1995.
Dr Wang's team concluded, "The number of gastroparesis-related hospitalizations has been increasing in the United States, suggesting an increasing prevalence of gastroparesis."
"The economic impact of gastroparesis-related hospitalizations is significant and increasing."
