Objectives: This study examines 9-year discharge patterns and changes in outcomes in oral cancer hospitalizations in the United States.
Study design: All hospitalizations with primary diagnosis of oral and oropharyngeal cancers were selected from 2000 to 2008 Nationwide Inpatient Sample. Association between outcomes (in-hospital mortality, length of stay [LOS], hospital charges, and discharge status) and independent variables was examined using multivariable regression analyses.
Results: Of 146,928 hospitalizations, 5310 died in hospitals. Mean LOS was 6.7 days. Mean hospitalization charges ranged from $47,331 to $62,885. After adjusting for confounders, in-hospital morality and charges did not vary while LOS decreased. Hospitalizations occurring in 2004-2008 were more likely to be discharged to long-term facilities (odds ratio = 1.24-1.59, P < .05) compared with those in 2000.
Conclusion: Our study demonstrates changes in longitudinal trends in socio-demographic and hospital-related factors. Our results do not provide compelling evidence on whether hospitals are saving cost or shifting cost to another type of facility.
