RESUMO

OBJECTIVES: To establish the epidemiological characteristics, ventilator management, and outcomes in patients with acute hypoxemic respiratory failure (AHRF), with or without acute respiratory distress syndrome (ARDS), in the era of lung-protective mechanical ventilation (MV). DESIGN: A 6-month prospective, epidemiological, observational study. SETTING: A network of 22 multidisciplinary ICUs in Spain. PATIENTS: Consecutive mechanically ventilated patients with AHRF (defined as Pao2/Fio2 ≤ 300 mm Hg on positive end-expiratory pressure [PEEP] ≥ 5 cm H2O and Fio2 ≥ 0.3) and followed-up until hospital discharge. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Primary outcomes were prevalence of AHRF and ICU mortality. Secondary outcomes included prevalence of ARDS, ventilatory management, and use of adjunctive therapies. During the study period, 9,803 patients were admitted: 4,456 (45.5%) received MV, 1,271 (13%) met AHRF criteria (1,241 were included into the study: 333 [26.8%] met Berlin ARDS criteria and 908 [73.2%] did not). At baseline, tidal volume was 6.9 ± 1.1 mL/kg predicted body weight, PEEP 8.4 ± 3.1 cm H2O, Fio2 0.63 ± 0.22, and plateau pressure 21.5 ± 5.4 cm H2O. ARDS patients received higher Fio2 and PEEP than non-ARDS (0.75 ± 0.22 vs 0.59 ± 0.20 cm H2O and 10.3 ± 3.4 vs 7.7 ± 2.6 cm H2O, respectively [p < 0.0001]). Adjunctive therapies were rarely used in non-ARDS patients. Patients without ARDS had higher ventilator-free days than ARDS (12.2 ± 11.6 vs 9.3 ± 9.7 d; p < 0.001). All-cause ICU mortality was similar in AHRF with or without ARDS (34.8% [95% CI, 29.7-40.2] vs 35.5% [95% CI, 32.3-38.7]; p = 0.837). CONCLUSIONS: AHRF without ARDS is a very common syndrome in the ICU with a high mortality that requires specific studies into its epidemiology and ventilatory management. We found that the prevalence of ARDS was much lower than reported in recent observational studies.

RESUMO

PURPOSE: Frailty is a common condition among critically ill patients. Usually evaluated in a mixed population of medical, cardiac and surgical patients, we aimed to assess the impact of frailty on short- and long-term mortality exclusively in critically ill older medical patients. MATERIALS AND METHODS: We included 285 patients aged≥70 years admitted to ICU (2009-2017). Comorbidities, severity scores, treatment intensity and complications were recorded. Pre-hospital frailty, measured by Clinical Frailty Scale (CFS), was defined as a score ≥ 5 according to this scale. RESULTS: Prevalence of frailty (CFS ≥ 5) of 18.6%. Frail patients were more likely to be female (64.2% vs. 35.6%, p < .001) or suffer from heart failure (17% vs. 6%,p = .021). Apache II score was higher in frail than in non-frail patients (27.4 ±â€¯7.1 vs. 24.8 ±â€¯8.6,p = .041). Age, comorbidities, treatment intensity, complications, and ICU and hospital length of stay were similar between frail and non-frail patients. Life-sustaining treatment limitation was more frequent in frail patients (47.2% vs. 20.7%,p < .001). Except for ICU mortality, frailty was an independent predictor of short- and long-term mortality after adjustment for sociodemographic, comorbidities, severity scores, treatment intensity and complications. CONCLUSIONS: Frailty (CFS ≥ 5) was independently associated with short- and long-term mortality in older patients admitted to ICU exclusively due to a medical reason.

RESUMO

Patients on renal replacement therapy (RRT) infected with the human immunodeficiency virus (HIV) are a special group with growing interest. In order to study the epidemiological data of HIV+ patients on RRT in Spain, we collected individual information from 2004-2011 (period of use of highly active antiretroviral therapy [HAART] in the Autonomous Communities of Andalusia, Aragon, Asturias, Catalonia, Valencia, Castilla la Mancha, Castilla León, Galicia, Madrid, La Rioja and the Basque Country, comprising 85% of the Spanish population. A total of 271 incident and 209 prevalent patients were analysed. They were compared with the remaining patients on RRT during the same period. The annual incidence was 0.8 patients per one million inhabitants, with a significant increase during the follow-up period. The proportion of prevalent HIV+ patients was 5.1 per 1,000 patients on RRT (95% confidence interval [CI] 4.4-5.8. Although glomerular diseases constituted the majority of cases (42%), diabetic nephropathy was the cause in 14% of patients. The nation-wide totals for these percentages were 13 and 25%, respectively. Compared to the total of patients in treatment, the risk of death was significantly higher in the HIV+ group: hazard ratio (HR) adjusted for age, sex and diabetes was 2.26 (95% CI 1.74 - 2.91). Hepatitis C coinfection increased the risk of death in the HIV+ group (HR 1.77; 95% CI 1.10 - 2.85). The probability of kidney transplantation in HIV+ was only 17% after 7 years, comparing with total RTT patients (HR 0.15; 95% CI: 0.10-0.24). Despite the use of HAART, the incidence of HIV+ patients on dialysis has increased; their mortality still exceeds non-HIV patients, and they have a very low rate of transplantation. It is necessary to further our knowledge of this disease in order to improve results.
