Effectiveness of a Multifaced Antibiotic Stewardship Program: A Pre-Post Study in Seven Italian ICUs.

Multidrug resistance has become a serious threat for health, particularly in hospital-acquired infections. To improve patients' safety and outcomes while maintaining the efficacy of antimicrobials, complex interventions are needed involving infection control and appropriate pharmacological treatments in antibiotic stewardship programs. We conducted a multicenter pre-post study to assess the impact of a stewardship program in seven Italian intensive care units (ICUs). Each ICU was visited by a multidisciplinary team involving clinicians, microbiologists, pharmacologists, infectious disease specialists, and data scientists. Interventions were targeted according to the characteristics of each unit. The effect of the program was measured with a panel of indicators computed with data from the MargheritaTre electronic health record. The median duration of empirical therapy decreased from 5.6 to 4.6 days and the use of quinolones dropped from 15.3% to 6%, both p < 0.001. The proportion of multi-drug-resistant bacteria (MDR) in ICU-acquired infections fell from 57.7% to 48.8%. ICU mortality and length of stay remained unchanged, indicating that reducing antibiotic administration did not harm patients' safety. This study shows that our stewardship program successfully improved the management of infections. This suggests that policy makers should tackle multidrug resistance with a multidisciplinary approach based on continuous monitoring and personalised interventions.

Differences in early, intermediate, and long-term mortality among elderly patients admitted to the ICU: results of a retrospective observational study.

BACKGROUND: Few studies have investigated both short- and long-term prognostic factors, and the differences between chronic and acute conditions in the very old critically ill patient. Our study aims to shed light in this field and to provide useful prognostic factors that may support clinical decisions in the management of the elderly. METHODS: Six ICUs collected data concerning 80-year-old (or more) patients admitted in 2015 and 2016 and followed-up until May 2018. Three prognostic models were developed: an in-hospital mortality model, a model for patients discharged from the hospital and entering follow-up, and an intermediate model for those alive after three days from ICU admission. RESULTS: Our centers admitted 1189 patients, 1071 (90.1%) had survived after three days from admission, 889 (74.8%) were discharged from the hospital, 701 (59.0%) survived six months after hospital discharge, 539 (45.3%) survived at the end of follow-up. Among survivors the median follow-up time was 810 days. Acute organ failures were the main causes of death in the hospital mortality multivariable model. These factors are modifiable and potentially a target for intervention to improve outcome. The model focused on mortality six months after hospital in patients that survived a three-day time-limited trial, showed a clear shift toward chronic diseases, unmodifiable factors crucial for prognostic assessment. This trend was even more evident at the end of follow-up. CONCLUSIONS: Among very old ICU patients, prognostic factors shift from acute to chronic conditions in passing from in-hospital to posthospital outcomes.

An Observational Veneto Research on Ventilator-Associated Pneumonia (OVeRVAP): attributable mortality and cumulative incidence of ventilator-associated pneumonia.

BACKGROUND: The relationship between ventilator-associated pneumonia (VAP) and mortality varies from study to study, and its entity is uncertain due a considerable variation in the attributable mortality. The aim of this study was to evaluate the relationship between VAP frequency and mortality in a cohort of mechanically ventilated patients. METHODS: A multicenter prospective observational study was conducted in 21 Intensive Care Units (ICUs). The patients were recruited from 2008 to 2010 within randomly selected periods. 842 patients of 2595 admitted, met the eligibility criteria and were enrolled in the study. The study's primary outcome was death by any cause in one of the ICUs. We modelled VAP occurrence as a time-dependent covariate and fitted a competing risk analysis model. We estimated the attributable mortality of VAP as the population-attributable fraction of ICU mortality. RESULTS: A total of 121 patients developed VAP (14.4%), for an incidence rate of 15.7 cases per 1000 ventilator days; of the 175 patients (20.8%) who died during the study period, 31 (25.6%) had VAP. The ICU mortality rate in the patients who developed VAP was 22.6 per 1000 ventilator days (95% CI: 15.9-32.1). We estimated an attributable mortality of 8.4%. CONCLUSIONS: In 8.4% of cases, VAP was the leading cause of death in our study. This indicates that the patients died more frequently with VAP rather than because of it.

Therapeutic hypothermia in Italian Intensive Care Units after 2010 resuscitation guidelines: still a lot to do.

BACKGROUND: Therapeutic hypothermia (TH) is one of three interventions that have demonstrated to improve patients' neurological outcome after cardiac arrest. The aim of this study was to investigate the effect of the 2010 resuscitation guidelines on TH implementation in various Italian Intensive Care Units (ICU). METHODS: A structured questionnaire was submitted to Italian ICU. The questionnaire was addressed to determine the procedures of TH in each ICU or, on the contrary, the reason for not employing the therapy. RESULTS: We obtained complete information from 770 of 847 Italian ICU (91%). Out of 405 Units included in the analysis only 223 (55.1%) reported to use TH in comatose patients after return of spontaneous circulation. The trend of TH implementation shows a stable increase, particularly after 2006 but there is no evident acceleration after the strong indication of the 2010 guidelines. There was a rise of about 3.4 times in the number of Italian ICU using TH as compared to the 2007 survey (an increase of 68% per year). One hundred and eighty-two (44.9%) units did not use TH mainly because of lack of equipment, economic issues or the conviction of the difficulty of execution. CONCLUSIONS: TH is still under-used in Italy (55.1%) even though the therapy is strongly recommended in the 2010 guidelines. However, the increase in the adoption of hypothermia has been significant in the past 5 years (68%/years) and the awareness of the efficacy is almost consolidated among intensivists, being logistic problems the leading cause for non-adoption.

Use of recombinant activated factor VII in severe post-partum haemorrhage: data from the Italian Registry: a multicentric observational retrospective study.

PURPOSE: To report the Italian real experience in clinical practice about recombinant factor VII activated (rFVIIa) in Post-Partum Haemorrhage (PPH) treatment. METHODS: An Italian retrospective survey of severe primary PPH cases treated with rFVIIa was performed. Anamnestic, clinical and haemostatic data about thirty-five patients with PPH, from 2005 to 2007, were collected. Coagulative parameters and transfusion requirements before and after rFVIIa treatment were compared. RESULTS: After rFVIIa administration INR was significantly decreased, while fibrinogen levels were markedly increased. Median of packed red blood cells units, platelets units, fresh frozen plasma, crystalloids and colloids needed, before and after rFVIIa administration, were respectively 6 and 2 units (p<1.2exp-6), 1.5 and 0 units (p=0.001), 1250 and 0 mL (p<4.4exp-5), 3000 and 1250 mL (p<0,0042). Twenty-nine of 35 patients needed surgical intervention before rFVIIa administration, 9/35 after treatment. Hysterectomies have been performed respectively in 10/35 cases before and in 6/35 cases after rFVIIa infusion. No maternal deaths have been reported. No adverse events or thromboembolic complications were observed. CONCLUSIONS: Our clinical and haemostatic data suggest that recombinant activated factor VII may be a safe and helpful adjunctive therapy in the PPH management.

Acute renal failure from organophospate poisoning: a case of success with haemofiltration.

Severe organophosphate poisoning (OPP) has a high mortality rate. Respiratory and neurological complications are common in OPP. Multiple organ distress syndrome (MODS) and renal impairment are relatively rare but correlated with death. In previous publications, in patients who did not survive OPP, their deaths were due to MODS or acute renal failure. A case of intentional ingestion of an organophosphate with renal and multiple organ complications is described. In addition to the standard atropine/oxime regimen, continuous venous-venous haemofiltration (CVVH) therapy was started; the patient survived this intoxication. The pathogenesis of renal injury by OPP is unclear and more insight is required. In our experience, CVVH can be a valid therapy, considering in particular the toxicokinetics of the organophosphate.
