Nutritional Risk Screening 2002 as a Predictor of Outcome During General Ward-Based Noninvasive Ventilation in Chronic Obstructive Pulmonary Disease with Respiratory Failure

Nutrition practices in hospitalized adults receiving noninvasive forms of respiratory support: A scoping review

The use of noninvasive respiratory support is increasing, with noninvasive ventilation (NIV) and high-flow nasal cannula providing unique barriers to nutrition support. Limited data related to nutrition management for these patients in the intensive care unit (ICU) exist; however, the literature in non-critically ill patients is not well described, and its improvement may help to inform practice within the ICU. Therefore, a scoping review was conducted of MEDLINE, EmCare, and Cumulative Index of Nursing and Allied Health Literature (CINAHL) databases on August 18, 2022, to identify original publications that included adult patients receiving noninvasive respiratory support in a hospital setting with data related to nutrition management. Data were extracted on study design, population, details of respiratory support, and concepts relating to nutrition management (grouped into nutrition screening, assessment, delivery route, intake, and anthropometry). Eleven studies were included, most of which were small (<100 patients), single-center, observational trials in patients receiving NIV only. Five studies reported results related to route of nutrition and nutrition assessment, two on anthropometry, and one each on quantifying intake and nutrition screening; some studies reported multiple parameters. There was a lack of consensus regarding the ideal method for nutrition assessment and route of nutrition. Oral nutrition was the route most frequently reported, yet calorie and protein delivery via this route were inadequate, and barriers to intake included poor appetite, fatigue, and patient cognition. Future research should address barriers pertinent to this population and the impact of nutrition on outcomes.

Global prevalence of malnutrition in patients with chronic obstructive pulmonary disease: Systemic review and meta-analysis

BACKGROUND

Malnutrition is a significant comorbidity among chronic obstructive pulmonary disease (COPD), but it has been often ignored. To date, the prevalence of malnutrition and its association with clinical parameters in the patients with COPD have not been well described. We aimed to investigate the prevalence of malnutrition and the prevalence of at-risk for malnutrition among COPD and the clinical impact of malnutrition on patients with COPD in a systematic review and meta-analysis.

METHODS

PubMed, Embase, Cochrane Library, and Web of Science were searched for articles describing the prevalence of malnutrition and/or at-risk for malnutrition from January 2010 to December 2021. Eligibility screening, data extraction, and quality assessment of the retrieved articles were conducted independently by two reviewers. Meta-analyses were performed to determine the prevalence of malnutrition and at-risk for malnutrition and the clinical impact of malnutrition on patients with COPD. Meta-regression and subgroup analyses were performed to explore the sources of heterogeneity. Comparisons were made between individuals with and without malnutrition according to pulmonary function, degree of dyspnea, exercise capacity, and mortality risk.

RESULTS

Out of the 4156 references identified, 101 were read full-text, of which 36 studies were included. The total number of involved patients included in this meta-analysis was 5289. The prevalence of malnutrition was 30.0% (95% CI 20.3 to 40.6), compared with an at-risk prevalence of 50.0% (95% CI 40.8 to 59.2). Both prevalences were associated with regions and measurement tools. The prevalence of malnutrition was associated with COPD phase (acute exacerbations and stable). COPD with malnutrition showed lower forced expiratory volume 1 s % predicted (mean difference (MD) -7.19, 95% CI -11.86 to -2.52), higher modified Medical Research Council dyspnea scores (MD 0.38, 95% CI 0.12 to 0.64), poorer exercise tolerance (standardized mean difference -0.29, 95% CI -0.54 to -0.05), and higher mortality risk (hazard ratio 2.24, 95% CI 1.23 to 4.06) compared to COPD without malnutrition.

CONCLUSION

Malnutrition and at-risk for malnutrition are common among COPD. Malnutrition negatively impacts important clinical outcomes of COPD.

Nutritional State and COPD: Effects on Dyspnoea and Exercise Tolerance

Chronic Obstructive Pulmonary Disease (COPD) is a disease that is spreading worldwide and is responsible for a huge number of deaths annually. It is characterized by progressive and often irreversible airflow obstruction, with a heterogeneous clinical manifestation based on disease severity. Along with pulmonary impairment, COPD patients display different grades of malnutrition that can be linked to a worsening of respiratory function and to a negative prognosis. Nutritional impairment seems to be related to a reduced exercise tolerance and to dyspnoea becoming a major determinant in patient-perceived quality of life. Many strategies have been proposed to limit the effects of malnutrition on disease progression, but there are still limited data available to determine which of them is the best option to manage COPD patients. The purpose of this review is to highlight the main aspects of COPD-related malnutrition and to underline the importance of poor nutritional state on muscle energetics, exercise tolerance and dyspnoea.

[Nutritional risk and clinical outcomes in patients diagnosed with COVID-19 in a high-complexity hospital network]

INTRODUCTION

the identification of nutritional risk at hospital admission is important to establish timely interventions in the COVID-19 patient care cycle, due to a high risk of it being associated with complications.

OBJECTIVE

to determine the association between the level of nutritional risk upon admission and in-hospital mortality at 28 days in patients diagnosed with COVID-19 treated between March and October 2020 in two hospital institutions in Colombia.

METHODS

a retrospective, observational study. Hospitalized patients with a diagnosis of COVID-19 were included and assessed by the Nutrition Service using the nutritional risk identification in emergencies scale, adapted from the NRS 2002 scale. In-hospital mortality at 28 days was analyzed as the primary endpoint, and hospital stay, admission to Intensive Care Unit (ICU), and requirement for mechanical ventilation as secondary endpoints.

RESULTS

a total of 1230 patients were included, with a mean age of 65.43 ± 15.90 years, mainly men (57.1 %, n = 702). A high nutritional risk (≥ 2 points) was identified in 74.3 % (n = 914). Patients with a high nutritional risk had a greater probability of in-hospital death at 28 days (HRadj: 1.64; 95 % CI: 1.11-2.44), and a greater risk of requiring mechanical ventilation (OR = 1.78; 95 % CI: 1.11-2.86) or ICU admission (OR = 1.478; 95 % CI: 1.05-2.09), as well as hospital stay longer than 7 days (OR = 1.91; 95 % CI: 1.47-2.48).

CONCLUSIONS

patients with a diagnosis of COVID-19 at high nutritional risk had a significantly higher in-hospital mortality at 28 days and a higher probability of requiring mechanical ventilation, ICU admission, and prolonged hospital stay.

Non-Invasive Ventilation in a Non-Standard Setting – Is it Safe to Ventilate Outside the ICU?

Non-invasive ventilation (NIV) is considered a fundamental method in treating patients with various disorders, requiring respiratory support. Often the lack of beds in the intensive care unit (ICU) and the concomitant medical conditions, which refer patients as unsuitable for aggressive treatment in the ICU, highlight the need of NIV application in general non-monitored wards and unusual settings – most commonly emergency departments, high-dependency units, pulmonary wards, and even ambulances. Recent studies suggest faster improvement of all physiological variables, reduced intubation rates, postoperative pulmonary complications and hospital mortality with better outcome and quality of life by early well-monitored ward-based NIV compared to standard medical therapy in patients with exacerbation of a chronic obstructive pulmonary disease, after a surgical procedure or acute hypoxemic respiratory failure in hematologic malignancies. NIV is a ceiling of treatment and a comfort measure in many patients with do-not-intubate orders due to terminal illnesses. NIV is beneficial only by proper administration with appropriate monitoring and screening for early NIV failure. Successful NIV application in a ward requires a well-equipped area and adequately trained multidisciplinary team. It could be initiated not only by attending physicians, respiratory technicians, and nurses but also by medical emergency teams. Ward-based NIV is supposed to be more cost-effective than NIV in the ICU, but further investigation is required to establish the safety and efficacy in hospital wards with a low nurse to patient ratio.

Low Muscle Mass Is a Predictor of Malnutrition and Prolonged Hospital Stay in Patients With Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Longitudinal Study

BACKGROUND

Malnutrition in chronic obstructive pulmonary disease (COPD) patients is more prevalent during times of exacerbation. Fat-free mass index (FFMI), calf circumference (CC), and adductor muscle pollicis thickness (AMPT) can be used to identify reduced muscle mass and have been found to be good predictors of clinical outcomes in other conditions, but they have not been investigated in COPD. Therefore, this study evaluated low muscle mass as predictor of malnutrition, prolonged length of stay (LOS), and in-hospital death in COPD patients.

METHODS

This prospective cohort study was carried out in hospitalized patients with COPD exacerbation. Malnutrition diagnosis was performed by Subjective Global Assessment, and muscle mass was assessed by FFMI, calculated using fat-free mass from bioelectrical impedance, CC, and AMPT. Clinical outcomes (LOS and in-hospital death) were collected from records.

RESULTS

One hundred seventy-six patients were included (68.2 ± 10.4 years old, 56.2% women); 74.2% were classified as Global Initiative of Chronic Obstructive Lung Disease 2 or 3 and 58.2% as malnourished. The median LOS was 11 (7-19) days, and the incidence of death was 9.1%. Low FFMI and CC predicted malnutrition (low CC: odds ratio [OR], 4.6; 95% CI, 2.2-9.7 and low FFMI: OR, 8.8; 95% CI, 3.7-20.8) and were associated with prolonged LOS (low CC: OR, 2.3; 95% CI, 1.1-4.6 and low FFMI: OR, 2.5; 95% CI, 1.3-4.8).

CONCLUSION

Simple, inexpensive, and noninvasive parameters of muscle mass-FFMI and CC-are good predictors of malnutrition and prolonged LOS in COPD patients experiencing exacerbation.

Prediction of prognosis in chronic obstructive pulmonary disease patients with respiratory failure: A comparison of three nutritional assessment methods

OBJECTIVES

Due to their increased energy expenditure, chronic obstructive pulmonary disease (COPD) patients with respiratory failure are susceptible to malnutrition. This study aimed to compare the predictive values of the following three widely used nutritional assessment methods for the clinical prognosis of COPD patients with respiratory failure: body mass index (BMI), Nutritional Risk Screening 2002 (NRS 2002), and serum albumin (ALB) level.

METHODS

COPD patients with respiratory failure treated in our center from June 2013 to June 2016 were retrospectively included. Patient BMI, NRS 2002 and ALB values were measured to assess their nutritional status. A multivariable analysis was conducted, and receiver operating characteristic (ROC) curves were generated to explore the predictive factors for clinical prognoses.

RESULTS

A total of 438 qualified patients were enrolled in our study. Multivariable analysis revealed that the BMI and ALB values independently predicted in-hospital mortality, the BMI and NRS 2002 predicted 1-year mortality, and all three methods (BMI, NRS 2002, and ALB) predicted 30-day readmission after discharge (P < 0.05). Regarding the results of the AUROC analysis, the optimal cutoff values that maximized the ability to predict the prognosis were an ALB level of 30.5 g/L for in-hospital mortality, an NRS 2002 score of 3 points for 1-year mortality, and an ALB level of 30.1 g/L for readmission within 30 days following discharge.

CONCLUSIONS

For COPD patients with respiratory failure, ALB level was superior for predicting in-hospital mortality and 30-day readmission after discharge, and NRS 2002 was superior for long-term prognosis of 1-year mortality.

Incidence and risk factors of incontinence-associated dermatitis among patients in the intensive care unit

OBJECTIVE

To investigate the incidence of incontinence-associated dermatitis (IAD) among patients in the intensive care unit (ICU) and to identify potential risk factors to establish a reference for clinical nursing work.

BACKGROUND

Patients in the ICU are susceptible to IAD. IAD is painful, reduces the patient's quality of life and adds to the workload of clinical medical staff. However, risk factors associated with IAD may differ between countries and healthcare settings.

DESIGN

Prospective cohort study METHODS: From November 2016 to November 2017, a prospective cohort study was conducted among109 patients in three Class 3, Grade A hospitals (comprising 9 ICUs in total) in Beijing. The Incontinence-associated Dermatitis and Its Severity (IADS) instrument in Chinese was applied to assess IAD. Univariate and multivariate logistic regression analyses were performed to identify risk factors for IAD.

RESULTS

The study population had 29 community-acquired and 80 nosocomial infections, and 26 (incidence: 23.9%) of these had IAD. On univariate analysis, a significant difference was observed between patients with and without IAD with respect to the following indices: Barthel index, Braden scale score, Nutritional Risk Screening 2002 (NRS2002) score, serum albumin level, occurrence of infection, faecal incontinence, frequency of faecal incontinence, stool property and double (faecal and urinary) incontinence and perineal assessment tool (PAT) score (p < 0.05). Multivariate logistic regression analysis showed that three factors entered the regression equation-that is, the Braden Scale Score, serum albumin level and double incontinence. Of these, the Braden Scale Score and serum albumin level were protective factors for IAD. Thus, the higher the Braden Scale Score, the lower the risk of IAD (OR = 0.678, 95% confidence interval [CI] = 0.494-0.931); a higher level of serum albumin implies a lower risk of IAD, provided it is within the normal range (OR = 0.884, 95%CI = 0.797-0.981). Double incontinence was an independent risk factor for IAD (OR = 10.512, 95% CI = 2.492-44.342).

CONCLUSION

A higher morbidity of IAD is seen in the ICU. Specific preventive and nursing measures are required to maintain the skin integrity of critically ill patients in daily nursing practice to improve patient quality of life and the quality of nursing care.

RELEVANCE TO CLINICAL PRACTICE

Incontinence-associated dermatitis is characterised by inflammation and tissue damage due to prolonged/repeated exposure to urine and/or stool. Not every patient with urine and/or stool incontinence develops IAD. Medical staff can use research-based evidence to identify ICU patients at risk of IAD to reduce morbidity and improve health outcomes.

Mortality in acute non-invasive ventilation

A prospective study of non-invasive ventilation at The Prince Charles Hospital outside of the intensive care unit from March 2015 to March 2016 was performed. Overall 69 patients were included. Acute hypercapnic respiratory failure was the most common indication (n = 59; 85%). 49 (71%) had multifactorial respiratory failure. 15 (22%) patients died. Premorbid inability to perform self-care (P = 0.001) and the combination of mean pH < 7.25 and mean PaCO₂ ≥ 75 mmHg within 2 h of NIV initiation (P = 0.037) were significantly associated with mortality. There was a non-significant association between older age and mortality.

Update: non-invasive ventilation in chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) remains a common cause of morbidity and mortality worldwide. Patients with COPD and respiratory failure, whether acute or chronic have a poorer prognosis than patients without respiratory failure. Non-invasive ventilation (NIV) has been shown to be a useful tool in both the acute hospital and chronic home care setting. NIV has been well established as the gold standard therapy for acute decompensated respiratory failure complicating an acute exacerbation of COPD with reduced mortality and intubation rates compared to standard therapy. However, NIV has been increasingly used in other clinical situations such as for weaning from invasive ventilation and to palliate symptoms in patients not suitable for invasive ventilation. The equivocal evidence for the use of NIV in chronic hypercapnic respiratory failure complicating COPD has recently been challenged with data now supporting a role for therapy in selected subgroups of patients. Finally the review will discuss the emerging role of high flow humidified therapy to support or replace NIV in certain clinical situation.
