Our study findings of rural-urban and socioeconomic status disparities for MI hospitalizations in patients with RA provide policymakers with data and information for action.

- Population
- Hospitalized patients with rheumatoid arthritis (RA), 2016–2019 US National Inpatient Sample
- Exposure
- Rural vs urban residence in patients with RA
- Outcome
- MI hospitalization

Main finding
As reported in the abstract
Adjusted odds ratio
1.70
P < 0.001
Observational data: associations, not effects.

| Outcome | aOR | P value |
|---|---|---|
| MI hospitalization by median household income quartile (vs lowest quartile)Second-highest income quartile vs Lowest income quartile | 0.87 | P < 0.001 |
| MI hospitalization by median household income quartile (vs lowest quartile)Highest income quartile vs Lowest income quartile | 0.92 | P = 0.01 |
- Hospital charges and myocardial infarction (MI) hospitalization costs
- P > 0.05
- MI hospitalization by median household income quartile (vs lowest quartile): 2 highest quartiles; abstract lists aORs 0.87 and 0.92 in this order
- MI hospitalization by median household income quartile (vs lowest quartile): 2 highest quartiles; abstract lists aORs 0.87 and 0.92 in this order
Hospital charges and MI hospitalization costs
- Rural residence not significantly associated with higher hospital charges or MI hospitalization costs
Other factors associated with lower odds of MI hospitalization
- Female sex, African American race, elective admission, Medicare payer, government hospital ownership, rural hospital location and small hospital bed size significantly associated with lower odds of MI hospitalization
