INTRODUCTION: Although gastric cancer (GC) rates have been declining in the United States, it continues to be a major cause of morbidity. This study examined trends in hospital admissions, in-hospital mortality, length of stay (LOS), and inpatient costs related to GC. In addition, various factors associated with in-hospital mortality, LOS, and inpatient costs were examined.

METHODS: National inpatient sample-the largest publicly available all-payer inpatient care database-was interrogated to obtain information about various demographic and hospital-related factors (including those mentioned above) in patients who were primarily admitted for GC between the years 1998 to 2013. These trends were analyzed. Multivariate analysis was also performed to identify risk factors associated with LOS, costs, and mortality.

RESULTS: A total of 679,330 hospital discharges with the principal diagnosis of GC were obtained. Hospital stays increased by approximately 340 stays per year (±110; P=0.00079). However, inpatient mortality rate and LOS declined by 0.36% per year (±0.024%; P<0.0001), and 0.11 days per year (±0.01; P<0.0001), respectively. The inpatient charges have increased at the rate of $3241 per year (±133.3; P<0.0001). Differences in mortality rate, LOS, and inpatient costs were affected by multiple factors.

CONCLUSIONS: Despite the overall decline in GC incidence, the incidence of hospitalizations per 100,000 US population related to GC did not change significantly. Although LOS and mortality declined, inpatient charges increased over the study period.
