Characteristics, Outcomes, and Predictability of Critically Ill Obstetric Patients: A Multicenter Prospective Cohort Study.

OBJECTIVE: To evaluate pregnant/postpartum patients requiring ICUs admission in Argentina, describe characteristics of mothers and outcomes for mothers/babies, evaluate risk factors for maternal-fetal-neonatal mortality; and compare outcomes between patients admitted to public and private health sectors. DESIGN: Multicenter, prospective, national cohort study. SETTING: Twenty ICUs in Argentina (public, 8 and private, 12). PATIENTS: Pregnant/postpartum (< 42 d) patients admitted to ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Three hundred sixty-two patients were recruited, 51% from the public health sector and 49% from the private. Acute Physiology and Chronic Health Evaluation II was 8 (4-12); predicted/observed mortality, 7.6%/3.6%; hospital length of stay, 7 days (5-13 d); and fetal-neonatal losses, 17%. Public versus private health sector patients: years of education, 9 ± 3 versus 15 ± 3; transferred from another hospital, 43% versus 12%; Acute Physiology and Chronic Health Evaluation II, 9 (5-13.75) versus 7 (4-9); hospital length of stay, 10 days (6-17 d) versus 6 days (4-9 d); prenatal care, 75% versus 99.4%; fetal-neonatal losses, 25% versus 9% (p = 0.000 for all); and mortality, 5.4% versus 1.7% (p = 0.09). Complications in ICU were multiple-organ dysfunction syndrome (34%), shock (28%), renal dysfunction (25%), and acute respiratory distress syndrome (20%); all predominated in the public sector. Sequential Organ Failure Assessment (during first 24 hr of admission) score of at least 6.5 presented the best discriminative power for maternal mortality. Independent predictors of maternal-fetal-neonatal mortality were Acute Physiology and Chronic Health Evaluation II, education level, prenatal care, and admission to tertiary hospitals. CONCLUSIONS: Patients spent a median of 7 days in hospital; 3.6% died. Maternal-fetal-neonatal mortality was determined not only by acuteness of illness but to social and healthcare aspects like education, prenatal control, and being cared in specialized hospitals. Sequential Organ Failure Assessment (during first 24 hr of admission), easier to calculate than Acute Physiology and Chronic Health Evaluation II, was a better predictor of maternal outcome. Evident health disparities existed between patients admitted to public versus private hospitals: the former received less prenatal care, were less educated, were more frequently transferred from other hospitals, were sicker at admission, and developed more complications; maternal and fetal-neonatal mortality were higher. These findings point to the need of redesigning healthcare services to account for these inequities.

Ventilatory Parameters in Obstetric Patients With COVID-19 and Impact of Delivery: A Multicenter Prospective Cohort Study.

BACKGROUND: Current evidence on obstetric patients requiring advanced ventilatory support and impact of delivery on ventilatory parameters is retrospective, scarce, and controversial. RESEARCH QUESTION: What are the ventilatory parameters for obstetric patients with COVID-19 and how does delivery impact them? What are the risk factors for invasive mechanical ventilation (IMV) and for maternal, fetal, and neonatal mortality? STUDY DESIGN AND METHODS: Prospective, multicenter, cohort study including pregnant and postpartum patients with COVID-19 requiring advanced ventilatory support in the ICU. RESULTS: Ninety-one patients were admitted to 21 ICUs at 29.2 ± 4.9 weeks; 63 patients (69%) delivered in ICU. Maximal ventilatory support was as follows: IMV, 69 patients (76%); high-flow nasal cannula, 20 patients (22%); and noninvasive mechanical ventilation, 2 patients (2%). Sequential Organ Failure Assessment during the first 24 h (SOFA24) score was the only risk factor for IMV (OR, 1.97; 95% CI, 1.29-2.99; P = .001). Respiratory parameters at IMV onset for pregnant patients were: mean ± SD plateau pressure (PP), 24.3 ± 4.5 cm H2O; mean ± SD driving pressure (DP), 12.5 ± 3.3 cm H2O; median static compliance (SC), 31 mL/cm H2O (interquartile range [IQR], 26-40 mL/cm H2O); and median Pao2 to Fio2 ratio, 142 (IQR, 110-176). Respiratory parameters before (< 2 h) and after (≤ 2 h and 24 h) delivery were, respectively: mean ± SD PP, 25.6 ± 6.6 cm H2O, 24 ± 6.7 cm H2O, and 24.6 ± 5.2 cm H2O (P = .59); mean ± SD DP, 13.6 ± 4.2 cm H2O, 12.9 ± 3.9 cm H2O, and 13 ± 4.4 cm H2O (P = .69); median SC, 28 mL/cm H2O (IQR, 22.5-39 mL/cm H2O), 30 mL/cm H2O (IQR, 24.5-44 mL/cm H2O), and 30 mL/cm H2O (IQR, 24.5-44 mL/cm H2O; P = .058); and Pao2 to Fio2 ratio, 134 (IQR, 100-230), 168 (IQR, 136-185), and 192 (IQR, 132-232.5; P = .022). Reasons for induced delivery were as follows: maternal, 43 of 71 patients (60.5%); maternal and fetal, 21 of 71 patients (29.5%); and fetal, 7 of 71 patients (9.9%). Fourteen patients (22.2%) continued pregnancy after ICU discharge. Risk factors for maternal mortality were BMI (OR, 1.10; 95% CI, 1.006-1.204; P = .037) and comorbidities (OR, 4.15; 95% CI, 1.212-14.20; P = .023). Risk factors for fetal or neonatal mortality were gestational age at delivery (OR, 0.67; 95% CI, 0.52-0.86; P = .002) and SOFA24 score (OR, 1.53; 95% CI, 1.13-2.08; P = .006). INTERPRETATION: Contrary to expectations, pregnant patient lung mechanics were similar to those of the general population with COVID-19 in the ICU. Delivery was induced mainly for maternal reasons, but did not change ventilatory parameters other than Pao2 to Fio2 ratio. SOFA24 score was the only risk factor for IMV. Maternal mortality was associated independently with BMI and comorbidities. Risk factors for fetal and neonatal mortality were SOFA24 score and gestational age at delivery.

Predictability of adverse outcomes in hypertensive disorders of pregnancy: a multicenter prospective cohort study.

OBJECTIVES: To explore variables associated with adverse maternal/fetal/neonatal outcomes among pregnant/postpartum patients admitted to ICU for hypertensive disorders of pregnancy (HDP). METHODS: Multicenter, prospective, national cohort study. RESULTS: Variables independently associated with maternal/fetal/neonatal mortality among 172 patients were as follows: Acute Physiology and Chronic Health Evaluation-II (APACHE-II)(OR1.20[1.06-1.35]), gestational age (OR0.698[0.59-0.82]) and aspartate aminotransferase (AST)(OR1.004[1.001-1.006]). Positive likelihood ratio for headache, epigastric pain, and visual disturbances to predict composite adverse outcomes were 1.23(1.16-1.30), 0.76(0.59-1.02), and 1.1(0.98-1.2), respectively. CONCLUSIONS: Maternal/fetal mortality due to HDP was independently associated with severity of illness on admission, gestational age, and elevated AST. Accuracy of clinical symptoms to predict composite adverse outcomes was low.

Clinical characteristics and outcomes of obstetric patients requiring ICU admission.

OBJECTIVES: To review a series of critically ill obstetric patients admitted to our ICU to assess the spectrum of disease, required interventions, and fetal/maternal mortality, and to identify conditions associated with maternal death. DESIGN: Retrospective cohort. SETTING: Medical-surgical ICU in a university-affiliated hospital. PATIENTS: Pregnant/postpartum admissions between January 1, 1998, and September 30, 2005. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: We studied 161 patients (age, 28 +/- 9 years; mean gestational age, 29 +/- 9 weeks) [mean +/- SD], constituting 10% of 1,571 hospital admissions. APACHE (acute physiology and chronic health evaluation) II score was 14 +/- 8, with 24% predicted mortality; sequential organ failure assessment score was 5 +/- 3; and therapeutic intervention scoring system at 24 h was 25 +/- 9. Forty-one percent of patients required mechanical ventilation (MV). ARDS, shock, and organ dysfunction were present in 19%, 25%, and 48% of patients, respectively. Most patients (63%) were admitted postpartum, and 74% of admissions were of obstetric cause. Hypertensive disease (40%), major hemorrhage (16%), septic abortion (12%), and nonobstetric sepsis (10%) were the principal diagnoses. Maternal mortality was 11%, with multiple organ dysfunction syndrome (44%) and intracranial hemorrhage (39%) as main causes. There were no differences in death rate in patients admitted for obstetric and nonobstetric causes. Fetal mortality was 32%. Only 30% of patients received antenatal care, which was more frequent in survivors (33% vs 6% nonsurvivors, p = 0.014). CONCLUSIONS: Although ARDS, organ failures, shock, and use of MV were extremely frequent in this population, maternal mortality remains within an acceptable range. APACHE II overpredicted mortality in these patients. Septic abortion is still an important modifiable cause of mortality. Efforts should concentrate in increasing antenatal care, which was clearly underprovided in these patients.

Symptom burden and health-related quality of life among intensive care unit survivors in Argentina: A prospective cohort study.

PURPOSE: Our goal was to describe the evolution of selected physical and psychologic symptoms and identify the determinants of health-related quality of life (HRQOL) after intensive care unit (ICU) discharge. METHODS: The study is a prospective cohort of consecutive adult patients admitted to a mixed ICU in a university-affiliated hospital, mechanically ventilated for more than 48 hours. During ICU stay, epidemiological data and events probably associated to worsening outcomes were recorded. After discharge, patients were interviewed at 1, 3, 6, and 12 months. Health-related quality of life was assessed with EuroQoL Questionnaire-5 Dimensions, which includes the EQ-index and EQ-Visual Analogue Scale. RESULTS: One hundred twelve patients were followed up, aged 33 [24-49] years, 68% male, 76% previously healthy, and cranial trauma was the main diagnosis. Physical and psychologic symptoms and moderate/severe problems according to the EQ index progressively decreased after discharge, yet were still highly prevalent after 1 year. EQ index improved from 0.22 [0.01-0.69] to 0.52 [0.08-0.81], 0.66 [0.17-0.79], and 0.68 [0.26-0.86] (P < .001, for all vs month 1). EQ-Visual Analogue Scale remained stable, within acceptable values. Independent determinants of EQ-index were time, duration of mechanical ventilation, shock, weakness, and return to study/work. CONCLUSIONS: Determinants of HRQOL after ICU discharge were both related to late sequelae of critical illness and to some events occurring in the ICU. Notwithstanding the high symptom burden, patients still perceived their HRQOL as good.

Hypertensive disease of pregnancy in the ICU: a multicenter study.

OBJECTIVE: To describe characteristics, outcomes and clinical presentations for hypertensive disease of pregnancy (HDP) in patients admitted to three ICUs in Argentina. METHODS: Case-series multicenter study. RESULTS: There were 184 patients with HDP. Mean age 26 ± 8; 90% did not present comorbidity; APACHEII 9[6-14]; SOFA24 2[1-4]; ICU-LOS 3[2-6] days and hospital-LOS 8[5-12] days. Gestational age 34 ± 5 weeks; 46% (85) nulliparous and 71% received routine prenatal care. Maternal mortality 3.3% (6) - 50% attributed to intracranial hemorrhage (ICH). Neonatal mortality 13.6%. Diagnostic categories: eclampsia (64; 35%), severe preeclampsia (60; 32.6%), HELLP (33; 17.9%), eclampsia-HELLP (18; 9.8%) and other (chronic/gestational-hypertension) (9: 4.7%). Severe hypertension in 46%, multiple organ dysfunction in 23%, acute respiratory distress in 8.7% and acute renal failure in 8%. Variables independently associated with eclampsia: maternal age (OR 1.07 [1.02-1.13], gestational age (OR 1.14 [1.04-1.24]) and nulliparity (OR 2.40 [1.19-4.85]). CONCLUSIONS: Although patients were young and the majority received appropriate prenatal care, they spent considerable time in hospital and presented severe morbidity. Maternal mortality was 3.3% and in half of these cases it was attributed to ICH. Eclampsia and severe preeclampsia represented two thirds of the diagnostic categories. Variables independently associated with eclampsia were maternal and gestational ages and nulliparity.

Health insurance status and outcomes of critically ill obstetric patients: a prospective cohort study in Argentina.

PURPOSE: In Argentina, uninsured patients receive public health care, and the insured receive private health care. Our aim was to compare different outcomes between critically ill obstetric patients from both sectors. METHODS: This is a prospective cohort, including pregnant/postpartum patients requiring admission to 1 intensive care unit in the public sector (uninsured) and 1 in the private (insured) from January 1, 2008, to September 30, 2011. RESULTS: A total of 151 patients were included in the study. In uninsured (n = 63) vs insured (n = 88) patients, Acute Physiology and Chronic Evaluation II (APACHE II) and Sequential Organ Failure Assessment scores were 11 ± 6.5 vs 8 ± 4 and 3 (2-7) vs 1 (0-2), respectively, and 84% vs 100% received prenatal care (P = .001 for all). Multiple organ dysfunction syndrome (MODS) was present in 32 (54%) uninsured vs 9 (10%) insured patients (P = .001), and acute respiratory distress syndrome developed in 18 (30.5%) of 59 vs 2(2%) of 88 (P = .001). Neonatal survival was 80% vs 96% (P = .003). Variables independently associated with the development of MODS were APACHE II (odds ratio, 1.30 [1.13-1.49]), referral from another hospital (odds ratio, 11.43 [1.86-70.20]), lack of health insurance (odds ratio 6.75 [2.17-20.09]), and shock (odds ratio 4.82 [1.54-15.06]). Three patients died, all uninsured. CONCLUSIONS: Uninsured critically ill obstetric patients (public sector) were more severely ill on admission and experienced worse outcomes than insured patients (private sector). Variables independently associated with MODS were APACHE II, shock, referral from another hospital, and lack of insurance.

Critical care providers' opinion on unsafe abortion in Argentina.

OBJECTIVE: To survey the opinion of critical care providers in Argentina about abortion. METHODS: An anonymous questionnaire was distributed to critical care providers attending the 20th National Critical Care Conference in Argentina. RESULTS: 149 of 1800 attendees completed the questionnaire, 69 (46.3%) of whom were members of the Argentine Society of Critical Care (ASCC). 122 (81.9%) supported abortion decriminalization in situations excluded from the current law; 142 (95.3%) in cases of congenital defects; 133 (89.3%) in cases of rape; 115 (77.2%) when women's mental health is at risk; 71 (47.7%) when pregnancy is unintended; and 61 (40.9%) for economic reasons. 126 (84.6%) supported abortion in public and private institutions, and 121 (81.2%) before 12 weeks of pregnancy. Variables independently associated with abortion support among female versus male attendees were abortion to preserve women's mental health (OR 4.47; 95% CI, 1.61-12.42; P=0.004) and abortion before 12 weeks of pregnancy (OR 3.93; 95% CI, 1.29-11.94; P=0.015). Abortion at request was independently associated with ASCC membership (OR 2.63; 95% CI, 1.07-6.45; P=0.034). CONCLUSION: Critical care providers would support abortion in situations excluded from the current abortion law and before 12 weeks of pregnancy, in both public and private hospitals.

Impacto de la internación en terapia intensiva en la calidad de vida después de 1, 3, 6 y 12 meses / The impact of hospitalization in intensive care units on quality of life after 1, 3, 6 and 12 months

INTRODUCCION: A medida que más pacientes sobreviven a una internación en Unidades de Terapia Intensiva (UTI), se hace necesario conocer las secuelas a largo plazo. La calidad de vida relacionada a la salud tras la enfermedad crítica se mantiene por debajo de la media de la población general aún cinco años después del alta.OBJETIVO: Evaluar la calidad de vida de los pacientes a egreso de UTI mediante el cuestionario EuroQol 5D y predictores de mala evolución. Evaluar secuelas psíquicas y físicas una vez transcurridos 1, 3, 6 y 12 meses después del alta de UTI.METODOS: Se realizó un estudio descriptivo en un Hospital Interzonal de la Provincia de Buenos Aires (estudio prospectivo de serie de casos). Fueron incluidos aquellos pacientes sometidos a asistencia respiratoria mecánica invasiva por un período ≥ 48 horas que egresaron de UTI entre el 01/04/2010 y el 01/04/2011.RESULTADOS: Los criterios de inclusión fueron cumplidos por 51 pacientes. Se entrevistó a 36/46 pacientes (tras un mes), 25/34 pacientes (a los 3 meses), 12/15 pacientes (a los 6 meses) y 5/7 pacientes (a los 12 meses). Los datos demográficos reflejaron edad 33 [25-50] años, 71% de los pacientes de sexo masculino, 57% sin comorbilidades y con un puntaje APACHE II de 14,6 ± 6. El principal motivo de ingreso fue el trauma (50%). La dimensión más afectada fue la realización de actividades cotidianas, seguida de dolor/malestar y movilidad. La incidencia de ansiedad/depresión y estrés postraumático fue la reportada en otros estudios. La anemia, la traqueostomía y la alimentación enteral al alta fueron predictores de mala evolución según el índice EuroQol.CONCLUSIONES: La calidad de vida al alta de UTI se encontró muy deteriorada en la mayoría de las dimensiones. Las secuelas psíquicas se presentaron dentro del rango esperado. El índice EuroQol fue bajo en el primer mes, pero evolucionó favorablemente junto a la percepción de la propia calidad de vida medida por Escala Visual Análoga EuroQol.

INTRODUCTION: As more and more patients survive their hospitalization in Intensive Care Units (ICU), it is of utmost importance to find out and understand the long-term outcomes. Health-related quality of life after a critical illness is still below the average, even five years after discharge.OBJECTIVE: To assess patients quality of life after ICU discharge using the EuroQol-5D score and predictors of unfavorable prognosis. To assess psychological after-effects like anxiety, depression and post-traumatic stress disorder (PTSD), along with physical morbodity at 1, 3, 6 and 12 months after ICU discharge.METHODS: A descriptive study was conducted in a public hospital located in the province of Buenos Aires (prospective case study). It included all patients treated with invasive mechanical ventilation for at least 48 hours that survived ICU from April 1, 2010 through April 1, 2011.RESULTS: 51 patients qualified for inclusion in this study. Interviews were made to 36/46 patients after 1 month; 25/34 patients after 3 months; 12/15 patients after 6 months and 5/7 patients after 12 months. The demographic data showed age 33 [25-50], 71% male, 57% with no comorbidities and 14,6 ± 6,4 points in APACHE II score. The main reason for ICU admission was trauma (50%). The most affected dimension, as measured by EQ-5D, was usual activities, followed by pain/discomfort and self-care or morbility. The incidence of PTSD and anxiety/depression was similar was to what was reported in other studies. Anemia, tracheostomy and enteral feeding at discharge were predictors of unfavorable prognosis as indicated by the EuroQol index.CONCLUSIONS: The quality of life after ICU discharge was severely deteriorated in most dimensions. Psychological after-effects were within the expected values. The EuroQol index was low in the first month, but then it improved along with the quality of life as measured by the EuroQol Visual Analogue Scale.
