Note. CI = confidence interval. We adjusted all models for age, payer, location of residence, and gender. The sample size was n = 162 152. Micronesian: n = 3486, 47.5% women; Native Hawaiian: n = 37 734, 51.2% women; Japanese: n = 49 105, 51.8% women; White: n = 71 827, 45.4% women.

^aThe 3M Health Information Systems severity of illness (SOI) score range was 1–4, with higher scores indicating worse SOI. 3M designed this metric to be used specifically in all patient refined–diagnosis related groups disease categories, and thus overall SOI may not be a meaningful metric. We have included it here because the information on the Micronesian population is limited, and it thus allows a broad comparison of SOI with other hospitalized racial/ethnic groups. However, it should not be considered a definitive measure of SOI overall for any population group considering these caveats.
