Socioeconomic class and universal healthcare: Analysis of stroke cost and outcomes in US military healthcare.

OBJECTIVE

Do socioeconomic disparities exist in the US military healthcare system with ischemic stroke admissions?

METHODS

Civilian healthcare in the United States is paid for by a variety of payers. Significant disparities exist in this system based upon socioeconomic status (SES). In contrast, the military healthcare system (MHS) is a universal healthcare system. Military rank is a SES surrogate. Data was collected from the MHS database for years 2010 through 2015. All admissions to military health care facilities with a primary diagnosis of ischemic stroke were reviewed. Military rank was compared for primary outcomes of: Disposition (In-hospital mortality and discharge destination setting) and IV tPA administration and for secondary outcomes of: Total cost of hospitalization and Length of hospital stay (LoS). All adjusted for relevant demographics and co-morbidities.

RESULTS

Military rank was identified with 1895 (52.3%) of the 3623 admissions. The ranks identified were: Junior Enlisted 100 (2.7%), Senior Enlisted/Warrant Officers 1390 (38.4%), Junior Officers 59 (1.6%) and Senior Officers 346 (9.6%). Statistically significant results included: Lower SES group/ranks were more likely to have poor discharge destination setting while the highest SES group/ranks and had lower rates of in-hospital mortality, shorter lengths of stay and higher hospitalization costs after controlling for relevant variables.

CONCLUSION

Higher military ranks (Higher SES) had shorter hospitalization stays, higher costs and less in-hospital mortality in the military's universal healthcare system. This suggests aggregate characteristics of SES plays a large role in the outcomes among SES groups.
