Crit Care Med 2015 • Volume 43 • Number 12 (Suppl.) preventable and non-preventable readmissions. We then calculated the incidence of preventable readmissions, summarized the causes of readmissions, and compared clinical characteristics between preventable and non-preventable readmissions Results: Of 136 patients in the final analysis, 16 (11.8%, 95% CI: 6.9% 18.4%) were considered preventable and 120 (88.2%, 95% CI: 81.5% 93.1%) were considered non-preventable. Of non preventable readmissions, 67 were due to a new clinical problem and 53 were due to an existing clinical problem. Among preventable readmissions, 6 were attributable to system errors, 6 were attributable to management errors, 2 were attributable to procedural events, 1 was attributable to a diagnostic error, and 1 was attributable to medication error. Compared to non-preventable readmissions, potentially avoidable readmissions tended to have shorter ICU lengths of stay (2 days vs. 3 days, p = 0.05) and a shorter duration of time on the ward prior to readmission (16.6 hr vs. 23.6 hr, p = 0.05) Conclusions: A large majority of early ICU readmissions are non-preventable, calling into question the value of the efforts to reduce ICU readmissions and raising important concerns about ICU readmission rates as a hospital performance measure.
