Thrombocytopenia and platelet transfusions in ICU patients: an international inception cohort study (PLOT-ICU)
Purpose
Thrombocytopenia (platelet count < 150 × 109/L) is common in intensive care unit (ICU) patients and is likely associated with worse outcomes. In this study we present international contemporary data on thrombocytopenia in ICU patients.
Methods
We conducted a prospective cohort study in adult ICU patients in 52 ICUs across 10 countries. We assessed frequencies of thrombocytopenia, use of platelet transfusions and clinical outcomes including mortality. We evaluated pre-selected potential risk factors for the development of thrombocytopenia during ICU stay and associations between thrombocytopenia at ICU admission and 90-day mortality using pre-specified logistic regression analyses.
Results
We analysed 1166 ICU patients; the median age was 63 years and 39.5% were female. Overall, 43.2% (95% confidence interval (CI) 40.4–46.1) had thrombocytopenia; 23.4% (20–26) had thrombocytopenia at ICU admission, and 19.8% (17.6–22.2) developed thrombocytopenia during their ICU stay. Non-AIDS-, non-cancer-related immune deficiency, liver failure, male sex, septic shock, and bleeding at ICU admission were associated with the development of thrombocytopenia during ICU stay. Among patients with thrombocytopenia, 22.6% received platelet transfusion(s), and 64.3% of in-ICU transfusions were prophylactic. Patients with thrombocytopenia had higher occurrences of bleeding and death, fewer days alive without the use of life-support, and fewer days alive and out of hospital. Thrombocytopenia at ICU admission was associated with 90-day mortality (adjusted odds ratio 1.7; 95% CI 1.19–2.42).
Conclusion
Thrombocytopenia occurred in 43% of critically ill patients and was associated with worse outcomes including increased mortality. Platelet transfusions were given to 23% of patients with thrombocytopenia and most were prophylactic.publishedVersio
THE DIVERSITY DIALOGUES IN HIGHER EDUCATION
It is hard to be an enemy of diversity. Most Americans recognize diversity as one of the nation’s proudest attributes. Beyond that, however, there is confusion over the term’s meaning. No matter how often people say the word, or how strongly they believe in it, they continue to ignore the way diversity has become an all-embracing concept. The term “diversity” has become a code word that fails to define precisely what it allegedly exalts and what exactly is to be accomplished by those who extol its virtues. The elasticity of the term “diversity” has masked many kinds of questionable conduct. Administrators have been invoking “diversity” without openly acknowledging that diversity has become “untethered from integration” to the point of becoming “integration’s rival.” Whatever the Supreme Court decides about the data regarding the effects of diversity on students’ academic performance, it is not likely to satisfy all of our college administrators, faculty, and students
