Abstract
BACKGROUND: Functional and motility disorders (FMDs) are common conditions that cause significant morbidity and economic loss. A comprehensive analysis of these disorders and their impact has not been done in an inpatient setting.
AIMS: We seek to evaluate adult hospitalization trends for FMDs in the USA.
METHODS: The National Inpatient Sample between 2005 and 2014 was analyzed. Poisson regression was used to assess hospitalization trends for FMDs referenced to non-FMD hospitalizations. Linear regression was used to assess cost per hospitalization and length of stay (LOS). All models were adjusted for age, sex, primary insurance, and Charlson comorbidity index.
RESULTS: Hospitalizations with FMDs as the primary diagnosis fell by an adjusted 2.46%/year over the study period (p < 0.001). The entirety of this reduction was explained by falling admissions for gastroesophageal reflux (adjusted reduction of 7.04%/year, p < 0.001). The hospitalization rate for all other FMDs (excluding gastroesophageal reflux) minimally increased by 0.75%/year (p = 0.001). Total cost of care for FMD hospitalizations remained relatively stable ($3.17 billion in 2014), while increasing for all other hospitalizations. Mean LOS for FMD hospitalization increased by an adjusted 0.025 days/year, but decreased by 0.038 days/year for all other hospitalizations (p < 0.001).
CONCLUSIONS: The hospitalization rate for gastroesophageal reflux fell between 2005 and 2014, but remained relatively stable to increase for all other FMDs. These trends may be due to increased proton pump inhibitor use, better patient/provider education, emphasis on outpatient management, and/or coding bias.
