Abstract
- Background/Aims
We aim to assess the influence of obesity on gastroparesis (GP) hospitalizations in the United States (US).
Methods
The National Inpatient Sample was analyzed from 2007-2017 to identify all adult hospitalizations with a primary discharge diagnosis of GP. They were subdivided based on the presence or absence of obesity (body mass index > 30). Hospitalization characteristics, procedural differences, all-cause inpatient mortality, mean length of stay (LOS), and mean total hospital charge (THC) were identified and compared.
Results
From 2007-2017, there were 140 293 obese GP hospitalizations accounting for 13.75% of all GP hospitalizations in the US. Obese GP hospitalizations were predominantly female (76.11% vs 64.36%, P < 0.001) and slightly older (51.9 years vs 50.8 years, P < 0.001) compared to the non-obese cohort. Racial disparities were noted as Blacks (25.49% vs 22%, P < 0.001) had higher proportions of GP hospitalizations with obesity compared to the non-obese cohort. Furthermore, we noted higher rates of inpatient upper endoscopy utilization (6.05% vs 5.42%, P < 0.001), longer mean LOS (5.71 days vs 5.32 days, P < 0.001), and higher mean THC ($53 373 vs $45 040, P < 0.001) for obese GP hospitalizations compared to the non-obese group. However, obese GP hospitalizations had lower rates of inpatient mortality (0.92% vs 1.33%, P < 0.001), and need for nutritional support with endoscopic jejunostomy (0.25 vs 0.56%, P < 0.001) and total parenteral nutrition (1.46% vs 2.33%, P < 0.001) compared to the non-obese cohort.
Conclusions
In the US, compared to non-obese, a higher proportion of obese GP hospitalizations were female and Blacks. Obese GP hospitalizations also had higher THC, LOS, and rates of upper endoscopy.
