Frailty in patients over 65 years of age admitted to Intensive Care Units (FRAIL-ICU). / Fragilidad en pacientes mayores de 65 años ingresados en cuidados intensivos (FRAIL-ICU).

OBJECTIVE: To estimate the prevalence of frailty in patients admitted to the Intensive Care Unit (ICU) and its impact upon ICU mortality at 1 and 6 months. DESIGN: A prospective observational cohort study was carried out. SETTING: Spanish ICU. INTERVENTION: None. PATIENTS AND METHODS: Patients≥65 years of age admitted to the ICU for>24hours. Variables were registered upon admission, and functional status was assessed by telephone calls 1 and 6 months after discharge from the ICU. MAIN STUDY VARIABLES: Age, gender, frailty (FRAIL scale), functional status (Barthel, Lawton, Clinical Dementia Rating and NUTRIC score), days of mechanical ventilation (MV), functional score (APACHE II and SOFA), ICU mortality, and mortality 1 and 6 months after ICU discharge. RESULTS: A total of 132 patients were evaluated, of which 46 were frail (34.9%). Age of the frail versus non-frail patients: 78.8±7.2 and 78.6±6.4 years, respectively (P=.43); male gender: 43.8% versus 56.3% (P=.10); SOFA score: 4.7±2.9 versus 4.6±2.9 (P=.75); MV: 33.3% versus 66.7% (P=.75); days of MV: 5.6±15 versus 4.3±8.1 (P=.57); ICU mortality 13% versus 6% (P = .14), mortality at 1 month 24% versus 8% (P = .01), mortality 6 months 32% versus 15% (P = .03). Frailty is associated with mortality at one month (OR = 3.5, P <.05, 95% CI (1.22-10.03) and at 6 months after discharge from the ICU (OR = 2.62, P <.05, 95% CI (1.04-6.56). CONCLUSIONS: Frailty was present in 35% of the patients admitted to the ICU, and was associated with mortality.

Relationship between intra-abdominal hypertension, outcome and the revised Atlanta and determinant-based classifications in acute pancreatitis.

BACKGROUND: The aim of this study was to analyse the relationship between intra-abdominal hypertension (IAH) and severity of acute pancreatitis (AP) measured by the revised Atlanta classification (RAC) and determinant-based classification (DBC). Secondary objectives were to assess IAH as a predictor of morbidity and mortality in the ICU. METHODS: This prospective international observational study included patients admitted to the ICU with AP and at least one organ failure. Information was collected on demographics, severity scores at admission using RAC and DBC, organ failure, mechanical ventilation, continuous renal replacement therapy (CRRT), surgery and mortality. Maximum intra-abdominal pressure (IAP) during ICU stay was used for analysis. RESULTS: Some 374 patients were included. The hospital mortality rate was 28·9 per cent. IAP was measured in 301 patients (80·5 per cent), of whom 274 (91·0 per cent) had IAH and 103 (34·2 per cent) acute compartment syndrome. A higher IAH grade was more likely in patients with severe AP (42 per cent for grade I versus 84 per cent for grade IV) and acute critical pancreatitis (9 versus 25 per cent; P = 0·001). Compared with grade I IAH, patients with grade IV had more infected necrosis (16 versus 28 per cent; P = 0·005), need for surgery (27 versus 50 per cent; P = 0·006), mechanical ventilation (53 versus 84 per cent; P = 0·007) and requirement for CRRT (22 versus 66 per cent; P < 0·001). IAH predicted shock (area under receiver operating characteristic (ROC) curve (AUC) 0·79, 95 per cent c.i. 0·73 to 0·84), respiratory failure (AUC 0·82, 0·77 to 0·87), renal failure (AUC 0·93, 0·89 to 0·96) and mortality (AUC 0·89, 0·86 to 0·93). CONCLUSION: IAH was associated with severity of AP classified according to both RAC and DBC systems. IAP grade can predict outcome of AP during ICU stay.
