Multivariable Analysis: Association of Hospital Survey Characteristics With 25% Shorter Than Expected Total Length of Stay
Characteristics | RRR | P Value |
---|---|---|
| ||
Annual ACU admissions (per 100) | 1.01 [1.00–1.02] | .092 |
Subspecialty presence (2–3 vs 0–1) | 0.82 [0.73–0.93] | .001 |
Subspecialty presence (4–6 vs 0–1) | 0.79 [0.67–0.93] | .006 |
ICU cross-trained nurses (yes vs no) | 1.12 [0.98–1.27] | .094 |
Intensity of therapy (4–6 points vs <4 points) | 1.16 [1.01–1.32] | .031 |
Intensity of therapy (>6 points vs <4 points) | 1.28 [1.09–1.52] | .003 |
Use of postoperative protocols (yes vs no) | 1.03 [0.92–1.16] | .566 |
Written ICU-to-ACU transfer process (yes vs no) | 0.85 [0.77–0.94] | .002 |
Discharge same day as chest tube or pacer wire removal (yes vs no) | 0.88 [0.80–0.97] | .010 |
Definitions for each variable are included in the Supplemental Material. ACU unit size, nurse-to-patient ratio, and multidisciplinary staff all dropped out of the model because of significant collinearity.
ACU, acute care unit; ICU, intensive care unit; RRR, relative risk ratio.
