Advanced practitioner-driven critical care outreach to reduce intensive care unit readmission mortality

Objectives: Intensive care unit (ICU) readmission is associated with poorer outcomes as compared to primary admissions. Recognizing new or recurrent critical care issues on the wards postICU discharge may improve outcomes, especially in those subsequently requiring readmission. Herein, we describe and evaluate a pilot surgical critical care outreach initiative to reduce mortality in patients ultimately requiring ICU readmission. Methods: Each patient discharged from the ICU was visited within 48 h by a Critical Care Advanced practitioner who examined the patient, reviewed the chart, recent laboratory results, and orders, and then communicated any concerns to the primary service. Patient demographics, outreach issues identified, and severity of issues were recorded prospectively. Retrospectively, patient outcomes were assessed including the need and timing of any ICU readmission and mortality both before and after outreach implementation. Results: Pre and postoutreach readmission rates were 2.41% (37/1534) versus 3.54% (54/1524), respectively ( P = 0.07). Mortality rates before and after outreach were 5.08% ( n = 78) versus 5.64% ( n = 86) overall ( P = 0.052) and 18.9% ( n = 7) versus 9.25% ( n = 5) for readmissions ( P = 0.21), respectively. Conclusions: Critical care outreach postICU discharge did not decrease readmission mortality in this pilot study. Further studies are required to evaluate its effects on not only readmission mortality but also readmission rates and timing along with the incident of subsequent ICU complications.
