Readmission to the ICU was not an independent risk factor for hospital mortality (HR for first readmission 0.88; p > 0.05).
Observational (n=10,210)
Yes
Readmission to the ICU is not an independent risk factor for hospital mortality when accounting for patient frailty and other clinical factors.
Effect estimate: HR 0.88
p-value: p=>0.05
OBJECTIVES: To determine factors independently associated with readmission to ICU and the independent association of readmission with subsequent mortality. DESIGN: Prospective multicenter observational study. SETTING: Forty ICUs in Australia and New Zealand. PATIENTS: Consecutive adult patients discharged alive from ICU to hospital wards between September 2009 and February 2010. INTERVENTIONS: Measurement of hospital mortality. MEASUREMENTS AND MAIN RESULTS: We studied 10,210 patients and 674 readmissions. The median age was 63 years (interquartile range, 49-74), and 6,224 (61%) were male. The majority of readmissions were unplanned (84.1%) but only deemed preventable in a minority (8.9%) of cases. Time to first readmission was shorter for unplanned than planned readmission (3.2 vs 6.9 d; p 0.05). In contrast, age (hazard ratio, 1.03), a medical diagnosis (hazard ratio, 1.43), inotrope use (hazard ratio, 3.47), and treatment limitation order (hazard ratio, 17.8) were all independently associated with outcome. CONCLUSIONS: In this large prospective study, readmission to ICU was not an independent risk factor for mortality.
Santamaria et al. (Thu,) conducted a observational in ICU readmission (n=10,210). Readmission to ICU was evaluated on Hospital survival (HR 0.88, p=>0.05). Readmission to the ICU was not an independent risk factor for hospital mortality (HR for first readmission 0.88; p > 0.05).
