Binary logistic regression analysis of clinical predictors for 90-day inpatient mortality.
| Variable | aOR | 95% CI | p |
|---|---|---|---|
| Age (by 1-year increment) * | 0.982 | (0.972–0.993) | 0.001 |
| Sex (male to female) | 0.982 | (0.773–1.246) | 0.88 |
| End-of-life trajectory | |||
| Terminal * | 2.482 | (1.730–3.561) | <0.001 |
| Frailty | 1.156 | (0.874–1.529) | 0.31 |
| Organ Failure | 1.0 | reference | |
| CCI (by 1-point increment) * | 1.12 | (1.063–1.179) | <0.001 |
| APACHE II (by 1-point increment) * | 1.045 | (1.029–1.062) | <0.001 |
| Unexpected hospital visits # | 1.111 | (0.878–1.406) | 0.38 |
CCI = Charlson Comorbidity Index; APACHE = Acute Physiology and Chronic Health Evaluation; aOR = adjusted odds ratio; 95% CI = confidence interval; * p < 0.05 was considered statistically significance in regression model; # visited the emergency department or hospitalized ≥3 times in the previous six months due to unpredicted causes.
