A family information brochure and dedicated website to improve the ICU experience for patients' relatives: an Italian multicenter before-and-after study.

PURPOSE: Good communication between ICU staff and patients' relatives may reduce the occurrence of post-traumatic stress disorder, anxiety or depression, and dissatisfaction with clinicians. An information brochure and website to meet relatives' needs were designed to explain in technical yet simple terms what happens during and after an ICU stay, to legitimize emotions such as fear, apprehension, and suffering, and to improve cooperation with relatives without increasing staff workload. The main outcomes were improved understanding of prognosis and procedures, and decrease of relatives' anxiety, depression, and stress symptoms. METHODS: In this prospective multicenter before-and-after study, a self-administered questionnaire was used to investigate relatives' understanding of prognosis, treatments, and organ dysfunction, families' satisfaction, and symptoms of anxiety, depression, and post-traumatic stress. RESULTS: A total of 551 relatives received questionnaires in nine Italian ICUs; 332 (60%) responded, 144 before and 179 after implementation of the brochure and website. Of the 179 relatives who responded after, 131 (73%) stated they had read the brochure and 34 (19%) reported viewing the website. The intervention was associated with increased correct understanding of the prognosis (from 69 to 84%, p = 0.04) and the therapeutic procedures (from 17 to 28%, p = 0.03). Multivariable analysis, together with non-modifiable factors (relative's gender, education level, relationship to patient, and patient status at ICU discharge), showed the intervention to be significantly associated with a lower incidence of post-traumatic stress symptoms (Poisson coefficient = -0.29, 95% CI -0.52/-0.07). The intervention had no effect on the prevalence of symptoms of anxiety and depression. CONCLUSION: An information brochure and website designed to meet relatives' needs improved family members' comprehension and reduced their prevalence of stress symptoms.

Drainage of pleural effusion in mechanically ventilated patients: time to measure chest wall compliance?

PURPOSE: Pleural effusion (PE) is commonly encountered in mechanically ventilated, critically ill patients and is generally addressed with evacuation or by fluid displacement using increased airway pressure (P(AW)). However, except when massive or infected, clear evidence is lacking to guide its management. The aim of this study was to investigate the effect of recruitment maneuvers and drainage of unilateral PE on respiratory mechanics, gas exchange, and lung volume. MATERIALS AND METHODS: Fifteen critically ill and mechanically ventilated patients with unilateral PE were enrolled. A 3-step protocol (baseline, recruitment, and effusion drainage) was applied to patients with more than 400 mL of PE, as estimated by chest ultrasound. Predefined subgroup analysis compared patients with normal vs reduced chest wall compliance (C(CW)). Esophageal and P(AW)s, respiratory system, lung and C(CW)s, arterial blood gases, and end-expiratory lung volumes were recorded. RESULTS: In the whole case mix, neither recruitment nor drainage improved gas exchange, lung volume, or tidal mechanics. When C(CW) was normal, recruitment improved lung compliance (81.9 [64.8-104.1] vs 103.7 [91.5-111.7] mL/cm H2O, P < .05), whereas drainage had no significant effect on total respiratory system mechanics or gas exchange, although it measurably increased lung volume (1717 vs 2150 mL, P < .05). In the setting of reduced C(CW), however, recruitment had no significant effect on total respiratory system mechanics or gas exchange, whereas pleural drainage improved respiratory system and C(CW)s as well as lung volume (42.7 [38.9-50.0] vs 47.0 [43.8-63.3], P < .05 and 97.4 [89.3-97.9] vs 126.7 [92.3-153.8] mL/cm H2O, P < .05 and 1580 vs 1750 mL, P < .05, respectively). CONCLUSIONS: Drainage of a moderate-sized effusion should not be routinely performed in unselected population of critically ill patients. We suggest that measurement of C(CW) may help in the decision-making process.

Enteral vs. intravenous ICU sedation management: study protocol for a randomized controlled trial.

BACKGROUND: A relevant innovation about sedation of long-term Intensive Care Unit (ICU) patients is the 'conscious target': patients should be awake even during the critical phases of illness. Enteral sedative administration is nowadays unusual, even though the gastrointestinal tract works soon after ICU admission. The enteral approach cannot produce deep sedation; however, it is as adequate as the intravenous one, if the target is to keep patients awake and adapted to the environment, and has fewer side effects and lower costs. METHODS/DESIGN: A randomized, controlled, multicenter, single-blind trial comparing enteral and intravenous sedative treatments has been done in 12 Italian ICUs. The main objective was to achieve and maintain the desired sedation level: observed RASS = target RASS ± 1. Three hundred high-risk patients were planned to be randomly assigned to receive either intravenous propofol/midazolam or enteral melatonin/hydroxyzine/lorazepam. Group assignment occurred through online minimization process, in order to balance variables potentially influencing the outcomes (age, sex, SAPS II, type of admission, kidney failure, chronic obstructive pulmonary disease, sepsis) between groups. Once per shift, the staff recorded neurological monitoring using validated tools. Three flowcharts for pain, sedation, and delirium have been proposed; they have been designed to treat potentially correctable factors first, and, only once excluded, to administer neuroactive drugs. The study lasted from January 24 to December 31, 2012. A total of 348 patients have been randomized, through a centralized website, using a specific software expressly designed for this study. The created network of ICUs included a mix of both university and non-university hospitals, with different experience in managing enteral sedation. A dedicated free-access website was also created, in both Italian and English, for continuous education of ICU staff through CME courses. DISCUSSION: This 'educational research' project aims both to compare two sedative strategies and to highlight the need for a profound cultural change, improving outcomes by keeping critically-ill patients awake.

Tight glycemic control may favor fibrinolysis in patients with sepsis.

OBJECTIVE: To investigate whether tight glycemic control, in patients with sepsis, may restore a normal fibrinolysis by lowering plasminogen activator inhibitor (PAI)-1 levels. DESIGN: Prospective randomized clinical trial. SETTING: Three Italian university hospital intensive care units. PATIENTS: Ninety patients with severe sepsis/septic shock. INTERVENTIONS: Patients were randomized to receive either tight glycemic control (treatment group, target glycemia, 80-110 mg/dL) or conventional glycemic control (control group, target glycemia, 180-200 mg/dL). MEASUREMENTS: Inflammation, coagulation, and fibrinolysis markers were assessed, along with Sepsis-related Organ Failure Assessment scores, >28 days. MAIN RESULTS: In the whole population, at enrolment, inflammation and coagulation were activated in >80 of 90 patients, whereas fibrinolysis, as assessed by PAI-1 activity and concentration, was impaired in only 34 patients. The extent of the inflammatory reaction or of the coagulation activation was unrelated to outcome. In contrast, 90-day mortality rate of the 34 patients in whom fibrinolysis was definitely inhibited at study entry was twice that of the 56 patients in whom fibrinolysis was intact (44% vs. 21%, p = 0.02). After randomization, during the study, daily glycemia averaged 112 +/- 23 mg/dL in the treatment group and 159 +/- 31 mg/dL in controls (p < 0.001), with total daily administered insulin 57 +/- 59 IU and 36 +/- 44 IU, respectively (p < 0.001). A small, but significant, enhancement of fibrinolysis could be observed in the treatment group, as indicated by the time course of PAI-1 activity (p < 0.001), PAI-1 concentration (p = 0.004), and plasmin-antiplasmin complexes (p < 0.001). Morbidity, rated with the Sepsis-related Organ Failure Assessment score, became significantly lower (p = 0.03) in the treatment group. CONCLUSIONS: Fibrinolysis inhibition, in severe sepsis/septic shock, seems to have a relevant pathogenetic role. In this context, tight glycemic control seems to reduce, with time, the fibrinolytic impairment and morbidity.
