Background: Thrombocytopenia is common in the intensive care unit. Potential mechanisms and etiologies behind this phenomenon are multiple and often entangled. We assessed the effect of a systematic approach, using routinely available tests, on the proportion of patients in whom the mechanism (primary objective) and etiology (secondary objective) of thrombocytopenia in a mixed intensive care unit (ICU) could be identified. Methods: Before-and-after study of all patients with thrombocytopenia was used. 'Before' group had no intervention. New standard operating procedures for thrombocytopenia management were introduced. In the 'After' group, bone marrow aspiration; determination of fibrinogen dosage, prothrombin time, factor V, D-dimers; assay of fibrin monomers, ferritin, triglycerides, lactic acid dehydrogenase, aspartate transaminase, alanine aminotransferase, vitamin B 12 , folates, reticulocytes, haptoglobin, and bilirubin were performed. Results: In the Before group (n = 20), the mechanism (central, peripheral, or mixed) was identified in 10 % versus 83% in After group (n = 23) (p < 0.001) (48% peripheral, 35% mixed). Before intervention, ≥1 etiology was identified in 15% versus 95.7% in the After group (p < 0.001). Conclusions: Systematic and extensive investigation using routine tests highlights the mechanisms and etiology of thrombocytopenia in most cases.

Background The death rate in intensive care units (ICUs) can reach 20%. More than half occurs after a decision of care withholding/withdrawal. We aimed at describing and evaluating the experience of ICU physicians and nurses involved in the end-of-life (EOL) procedure. Primary objective was the evaluation of the experience of EOL assessed by the CAESAR questionnaire. Secondary objectives were to describe factors associated with a low or high score and to examine the association between Numeric Analogic Scale and quality of EOL. Methods Consecutive adult patients deceased in 52 ICUs were included between April and June 2018. Characteristics of patients and caregivers, therapeutics and care involved after withdrawal were recorded. CAESAR score included 15 items, rated from 1 (traumatic experience) to 5 (comforting experience). The sum was rated from 15 to 75 (the highest, the best experience). Numeric Analogic Scale was rated from 0 (worst EOL) to 10 (optimal EOL). Results Five hundred and ten patients were included, 403 underwent decision of care withholding/withdrawal, and among them 362 underwent effective care withdrawal. Among the 510 patients, mean CAESAR score was 55/75 (± 6) for nurses and 62/75 (± 5) for physicians (P < 0.001). Mean Numeric Analogic Scale was 8 (± 2) for nurses and 8 (± 2) for physicians (P = 0.06). CAESAR score and Numeric Analogic Scale were significantly but weakly correlated. They were significantly higher for both nurses and physicians if the patient died after a decision of withholding/withdrawal. In multivariable analysis, among the 362 patients with effective care withdrawal, disagreement on the intensity of life support between caregivers, non-invasive ventilation and monitoring and blood tests the day of death were associated with lower score for nurses. For physicians, cardiopulmonary resuscitation the day of death was associated with lower score in multivariable analysis. Conclusion Experience of EOL was better in patients with withholding/withdrawal decision as compared to those without. Our results suggest that improvement of nurses’ participation in the end-of-life process, as well as less invasive care, would probably improve the experience of EOL for both nurses and physicians.
