Obesity-related hospitalization costs to the U.S. Navy, 1993 to 1998.
The objective of this work was to estimate the cost to the U.S. Navy for obesity-related hospital admissions by examining (1) inpatient utilization associated with obesity; (2) the rank order, probability, and total facility costs of obesity-related diagnosis-related groups (DRGs); and (3) expected inpatient expenses. The frequency and probability of inpatient events in the Navy's active duty population were derived from the Department of Defense's Retrospective Case Mix Analysis System. Medicare-based facility costs per DRG were estimated. These measures were combined in a decision-analytic model. Expected facility costs per obesity-related admission for active duty Navy personnel increased by age group from $3,328 for 18 to 24 year olds to $5,746 for 45 to 64 year olds. The annual avoidable inpatient cost for the Navy was estimated to be $5,842,627 for the top 10 obesity-related DRGs. Improvements to the Navy Physical Readiness Program and other interventions that may reduce obesity, obesity-related health care use, and the public economic burden should be pursued.
