TABLE 1.
The covariates used in this study and their d
| Covariate | Description | Mean (median; IQR) |
|---|---|---|
| AGE | Patient age in years, recorded at admission | 65.0 (67; 54‐78) |
| MALE | Male gender indicator | 47.5% (–) |
| DCO 4 | Code status at discharge (4 categories) | 84.3% (–) |
| HOSP PRIOR7 CT | Count of hospitalizations in the last 7 d prior to the current admission | 0.05 (0; 0‐0) |
| HOSP PRIOR8 30 CT | Count of hospitalizations in the last 8 to 30 d prior to the current admission | 0.11 (0; 0‐0) |
| LOS 30 | Length of stay, in days (with stays above 30 d truncated at 30 d) | 4.6 (3; 2‐5) |
| MEDICARE | Indicator for Medicare Advantage status | 58.8% (–) |
| DISCHDISP | Discharge disposition (home, skilled nursing, home health) | 72.7% (–) |
| LAPS2 | Laboratory‐based acuity of illness score, recorded at admission | 55.7 (49; 16‐84) |
| LAPS2DC | Laboratory‐based acuity of illness score, recorded at discharge | 44.5 (40; 24‐60) |
| COPS2 | Comorbidity and chronic condition score, updated monthly | 44.7 (24; 10‐66) |
| HCUPSGDC | Diagnosis supergroup classification | – |
| W (or Wi) | Treatment: Transitions Program intervention | 5.2% (–) |
| Y (or Yi) | Outcome: Nonelective readmission within 30 d postdischarge | 12.4% (–) |
A more comprehensive listing of characteristics, stratified respective to the implementation of the Transitions Program, as well as definitions of the HCUPSGDC variables, can be found in the Appendix S1. For binary variables, only means are presented; for DCO_4 and DISCHDISP, the quantities presented correspond to the proportion of discharges who were full code, and those disharged to home, respectively.
