Chronic Comorbid Illnesses Predict the Clinical Course of 866 Patients Requiring Prolonged Mechanical Ventilation in a Long-Term, Acute-Care Hospital

The Tri-Steps Model of Critical Conditions in Intensive Care: Introducing a New Paradigm for Chronic Critical Illness

Background: The prevailing model for understanding chronic critical illness is a biphasic model, suggesting phases of acute and chronic critical conditions. A major challenge within this model is the difficulty in determining the timing of the process chronicity. It is likely that the triad of symptoms (inflammation, catabolism, and immunosuppression [ICIS]) could be associated with this particular point. We aimed to explore the impact of the symptom triad (inflammation, catabolism, immunosuppression) on the outcomes of patients hospitalized in intensive care units (ICUs). Methods: The eICU-CRD database with 200,859 ICU admissions was analyzed. Adult patients with the ICIS triad, identified by elevated CRP (>20 mg/L), reduced albumin (<30 g/L), and low lymphocyte counts (<0.8 × 109/L), were included. The cumulative risk of developing ICIS was assessed using the Nelson-Aalen estimator. Results: This retrospective cohort study included 894 patients (485 males, 54%), with 60 (6.7%) developing ICIS. The cumulative risk of ICIS by day 21 was 22.5%, with incidence peaks on days 2-3 and 10-12 after ICU admission. Patients with the ICIS triad had a 2.5-fold higher mortality risk (p = 0.009) and double the likelihood of using vasopressors (p = 0.008). The triad onset day did not significantly affect mortality (p = 0.104). Patients with ICIS also experienced extended hospital (p = 0.041) and ICU stays (p < 0.001). Conclusions: The symptom triad (inflammation, catabolism, immunosuppression) during hospitalization increases mortality risk by 2.5 times (p = 0.009) and reflects the chronicity of the critical condition. Identifying two incidence peaks allows the proposal of a new Tri-steps model of chronic critical illness with acute, extended, and chronic phases.

Anticipating need for intensive care in the healthcare trajectory of patients with chronic disease: A qualitative study among specialists

Introduction

We investigated the reflections and perceptions of non-ICU physicians about anticipating the need for ICU admission in case of acute decompensation in patients with chronic disease.

Methods

We performed a qualitative multicentre study using semi-structured interviews among non-ICU specialist physicians. The interview guide, developed in advance, focused on 3 questions: (1) What is your perception of ICU care? (2) How do you think advance directives can be integrated into the patient’s healthcare goals? and (3) How can the possibility of a need for ICU admission be integrated into the patient’s healthcare goals? Interviews were recorded, transcribed and analysed by thematic analysis. Interviews were performed until theoretical saturation was reached.

Results

In total, 16 physicians (8 women, 8 men) were interviewed. The main themes related to intensive care being viewed as a distinct specialty, dispensing very technical care, and with major human and ethical challenges, especially regarding end-of-life issues. The participants also mentioned the difficulty in anticipating an acute decompensation, and the choices that might have to be made in such situations. The timing of discussions about potential decompensation of the patient, the medical culture and the presence of advance directives are issues that arise when attempting to anticipate the question of ICU admission in the patient’s healthcare goals or wishes.

Conclusion

This study describes the perceptions that physicians treating patients with chronic disease have of intensive care, notably that it is a distinct and technical specialty that presents challenging medical and ethical situations. Our study also opens perspectives for actions that could promote a pluridisciplinary approach to anticipating acute decompensation and ICU requirements in patients with chronic disease.

Characteristics and Risk Factors of Children Requiring Prolonged Mechanical Ventilation vs. Non-prolonged Mechanical Ventilation in the PICU: A Prospective Single-Center Study

BACKGROUND

Prolonged mechanical ventilation (PMV) has become an enormous challenge in intensive care units (ICUs) around the world. Patients treated with PMV are generally in poor health. These patients represent a select cohort with significant morbidity, mortality, and resource utilization. The status of children who have undergone PMV in China is unknown. Our goal is to investigate the prevalence and characteristics of pediatric patients with PMV, as well as the risk factors of PMV in the pediatric intensive care unit (PICU).

METHODS

The subjects were divided into two groups. The PMV group(MV ≥ 14 days) and the non-PMV group(2 days < MV <14 days). The baseline characteristics, treatments, mortality and other results between the two groups were compared. The risk factors associated with PMV were evaluated using univariate and multivariable analyses.

RESULTS

Of the 382 children enrolled, 127 (33.2%) received prolonged mechanical ventilation. The most common cause of MV in the PMV group was acute lung disease (48.0%), followed by acute circulatory system disease (26.0%), acute neurological disease (15.0%), postoperative monitoring (10.2%), and others (0.8%). Comorbidities were more prevalent among the PMV group (P = 0.004). The patients with PMV had a higher rate of premature birth (24.4 vs. 14.1%, P = 0.013) and higher PIM3 score at admission [5.6(3.0-9.9) vs. 4.1(1.7-5.5), P < 0.001]. The use of inotropes/vasopressors (63.8 vs. 43.1%, P < 0.001) was more common in patients with PMV compared with those in the non-PMV group. In the PMV group, the rate of extubation failure (39.4 vs. 6.7%, P < 0.001) was higher than the non-PMV group. The median hospital stay [35(23.0-50.0)d vs. 20(14.0-31.0)d, P < 0.001], PICU stay [22(15.0-33.0)d vs. 9(6.0-12.0)d, P < 0.001], hospitalization costs [¥391,925(263,259-614,471) vs. ¥239,497(158,723-350,620), P < 0.001], and mortality after 1-month discharge (22.0 vs. 1.6%, P < 0.001) were higher in the PMV group. Multivariate analysis revealed that age <1 year old, a higher PIM3 score at admission, prematurity, the use of inotropes or vasopressors, extubation failure, and ventilator mode on the first day of MV were associated with PMV.

CONCLUSIONS

The incidence and mortality of PMV in pediatric patients is surprisingly high. Premature infants or patients with severe disease or extubation failure are at higher risk of PMV. Patients with PMV exhibit a greater burden with regard to medical costs than those on non-PMV. It is important to establish specialized weaning units for mechanically ventilated patients with stable conditions.

Prolonged Mechanical Ventilation: Symptomatology, Well-Being, and Attitudes to Life

OBJECTIVE

Although prolonged mechanical ventilation (PMV) is increasingly common, little is known concerning patient symptom burden or attitudes toward PMV. This study aims to describe the mood, well-being, distressing symptoms, and attitudes toward prolonged ventilation among PMV patients treated either at home or long-term acute care (LTAC).

DESIGN

An observational study.

SETTING AND PARTICIPANTS

62 communicative participants treated with PMV, aged ≥18 years, insurees of a single HMO, treated at home hospital or LTAC specializing in ventilation in Jerusalem.

MEASURES

Sociodemographic characteristics; chronic conditions; functional status; symptom burden measured by revised Edmonton Symptomatic Assessment System (r-ESAS); attitudes toward PVM.

RESULTS

Participants were aged 61.7 ± 20.7 years, commonly suffered progressive neuromuscular disease (43.5%) or chronic lung disease (29%), were functionally dependent, treated at home (64.5%) or LTAC (35.5%), and had a mean PMV duration of 36.6 months (interquartile range 10.8-114.1). The 5-item, short Geriatric Depression Scale identified depression among 38% of participants, and was less at home vs LTAC (34% vs 44%, P < .001). Mean revised Edmonton Symptom Assessment System score was 24.5 ± 14.8 (maximum severity = 100), and participants reported severe or distressing symptoms for tiredness (27%/20%), pain (10%/25%), anxiety (16%/14%), depression (9%/21%), drowsiness (12%/17%), shortness of breath (9%/15%), poor appetite (7%/9%), and nausea (0%/10%). Impaired general well-being was reported as severe, moderate, mild, or none among 15%, 40%, 30%, and 15%, respectively. Only 1 patient had advance directives concerning ventilation prior to intubation, and when asked if they had to choose again today, 85% of patients would again opt for ventilation.

CONCLUSIONS AND IMPLICATIONS

Few PMV patients reported distressing symptoms, and 85% would choose ventilation if asked again. These findings might be useful in clinical practice to assist in decision making concerning prolonged ventilation.

Prolonged Mechanical Ventilation: A Comparison of Patients Treated at Home Compared With Hospital Long-Term Care

OBJECTIVE

To compare the characteristics of patients treated with invasive prolonged mechanical ventilation (PMV) at home or in hospital long-term care (HLTC), specifically focusing on medical and functional status, caregiver strain, 6-month outcomes, and health maintenance organization (HMO) costs.

DESIGN

Observational study.

SETTING

A single HLTC and home hospital, serving a defined catchment area in the greater Jerusalem area, Israel.

PARTICIPANTS

A total of 120 PMV patients aged ≥18 years, all insurees of the same HMO. All PMV patients in the local HMO were approached, of whom 46 of 47 home PMV and 74/76 HLTC patients were enrolled.

MEASUREMENTS

Medical and sociodemographic factors, Barthel Index, Short Geriatric Depression Score, modified Caregiver Strain Index; 6-month follow-up for hospitalization, infections, pressure sores, and mortality; HMO costs.

RESULTS

Home PMV was associated with younger age, improved functional status, financial difficulty, less comorbidity, and longer duration of PMV. Primary reasons for home PMV were degenerative neuromuscular disease and chronic lung disease, compared with acute illnesses with or without resuscitation among HLTC patients. Most home patients were alert and able to communicate (n = 40/46) versus HLTC (n = 22/74), and reported less depression. Caregiver strain was similar for home and HLTC. Among HLTC versus home patients, 6-month mortality (27% vs 7%, P = .012) and frequency of pressure sores (45% vs. 29%, P = .042) were higher in HLTC, with no differences for infection rates or hospitalization. In multivariate analyses, being treated at home with PMV was significantly associated with being able to communicate, lower age, financial difficulties, and improved functional status. HMO costs were one-third for home PMV versus HLTC.

CONCLUSIONS AND IMPLICATIONS

Differing profiles were described for home and HLTC PMV patients, with lower rates of depression, pressure sores, mortality, and one-third the cost to HMO at home. Caregiver strain was similar irrespective of site of care. With appropriate targeting for eligible patients, home PMV is a viable and financially beneficial option.

Metabolic and Nutritional Characteristics of Long-Stay Critically Ill Patients

Background: insufficient feeding is frequent in the intensive care unit (ICU), which results in poor outcomes. Little is known about the nutrition pattern of patients requiring prolonged ICU stays. The aims of our study are to describe the demographic, metabolic, and nutritional specificities of chronically critically ill (CCI) patients defined by an ICU stay >2 weeks, and to identify an early risk factor. Methods: analysis of consecutive patients prospectively admitted to the CCI program, with the following variables: demographic characteristics, Nutrition Risk Screening (NRS-2002) score, total daily energy from nutritional and non-nutritional sources, protein and glucose intakes, all arterial blood glucose values, length of ICU and hospital stay, and outcome (ICU and 90-day survival). Two phases were considered for the analysis: the first 10 days, and the next 20 days of the ICU stay. Statistics: parametric and non-parametric tests. Results: 150 patients, aged 60 ± 15 years were prospectively included. Median (Q1, Q3) length of ICU stay was 31 (26, 46) days. The mortality was 18% at ICU discharge and 35.3% at 90 days. Non-survivors were older (p = 0.024), tended to have a higher SAPSII score (p = 0.072), with a significantly higher NRS score (p = 0.033). Enteral nutrition predominated, while combined feeding was minimally used. All patients received energy and protein below the ICU’s protocol recommendation. The proportion of days with fasting was 10.8%, being significantly higher in non-survivors (2 versus 3 days; p = 0.038). Higher protein delivery was associated with an increase in prealbumin over time (r² = 0.19, p = 0.027). Conclusions: High NRS scores may identify patients at highest risk of poor outcome when exposed to underfeeding. Further studies are required to evaluate a nutrition strategy for patients with high NRS, addressing combined parenteral nutrition and protein delivery.
