Abstract

Background The aim of this study was to investigate obese gastroparesis (GP) hospitalizations in the United States (US). Methods We analyzed the National Inpatient Sample (NIS) from 2007-2017 to identify all adult obese (body mass index ≥30 kg/m2) GP hospitalizations. These were compared with non-obese GP hospitalizations. The demographic trends, adverse outcomes, and healthcare burden were analyzed. Results From 2007-2017, obese GP hospitalizations accounted for 13.75% of all GP hospitalizations in the US. There was an increasing trend in obese GP hospitalizations, from 2286 in 2007 to 47,265 in 2017 (P=0.0019), and in the proportion of obese GP hospitalizations, from 6.16% in 2007 to 17.96% in 2017 (P<0.001). Males, Blacks, Hispanics, and Asians showed a rising trend in obese GP hospitalizations. Although rates of upper endoscopy declined from 8.28% in 2007 to 5.36% in 2017 (P<0.001), obese GP hospitalizations had higher rates of upper endoscopy utilization (6.05 vs. 5.42%, P<0.001) compared to the non-obese cohort. Inpatient mortality for obese GP hospitalizations increased from 0.64% in 2007 to 1.10% in 2017 (P<0.001). Furthermore, we noted a rising trend in mean length of stay (LOS), from 4.64 in 2007 to 6.05 days in 2017 (P=0.0029), and mean total hospital charge (THC), from $22,306 in 2007 to $62,220 in 2017 (P<0.001) for obese GP hospitalizations. Conclusions The prevalence of obese GP hospitalizations along with inpatient mortality, LOS, and THC rose significantly. However, the overall rate of upper endoscopy utilization has decreased for these patients.
